How do you feel about expectantly managing a well-dated pregnancy past 41 weeks’ gestation?

Is it reasonable to choose the age of 40 for proposing an anticipation of labor induction?

In physiologic ongoing pregnancies (whether they are spontaneous or autologous in vitro fertilization [IVF] or heterologous IVF), the evidence for anticipating labor induction based upon the only factor of age (after 40 years) is missing. Nonetheless, the number of women becoming pregnant at an older age is expected to increase, and from my perspective, to induce all physiologic pregnancies at term by 41 weeks and 5 days’ gestation does not appear to be best practice. I favor the idea of all women aged 40 and older to start labor induction earlier (for instance, to offer labor induction, with proper informed consent, by 41+ 0 and not 41+ 5 through 42+ 0 weeks of pregnancy).

At Brigham and Women’s Hospital in Boston, Massachusetts, our approach is to offer women ≥40 years of age induction of labor (IOL) at 39 weeks’ gestation, unless there is an obstetric contraindication to IOL. We believe that IOL at 39 weeks’ gestation is associated with a reduced risk of both cesarean delivery and a new diagnosis of hypertension.¹

OCs and spironolactone study

I often recommend oral contraceptives (OCs) containing drospirenone for patients with polycyctic ovary syndrome (PCOS)-associated mild acne and hirsutism—since OCs are already approved by the US Food and Drug Administration for acne, with similar effects as spironolactone. My patients seem to do well on an OC, and require only one medication. Of course, I would add spironolactone to the treatment regimen and switch OCs if she was not responding well.

Dr. Barbieri responds

The Endocrine Society agrees with Dr. Cane’s approach, recommending the initiation of monotherapy with an estrogen-progestin followed by the addition of spironolactone if 6 months of monotherapy produces insufficient improvement in dermatologic symptoms of PCOS, including hirsutism and acne. Most contraceptives contain 3 mg or 4 mg of drospirenone, which is thought to have antiandrogenic effects similar to spironolactone 25 mg. I believe that spironolactone 100 mg provides more complete and rapid resolution of the dermatologic symptoms caused by PCOS. Hence, I initiate both an estrogen-progestin contraceptive with spironolactone.

CASE Woman with bleeding in early pregnancy

A 31-year-old woman (G1P0) presents to the local emergency department (ED) due to bleeding in pregnancy. She reports a prior open appendectomy for ruptured appendix; she denies a history of sexually transmitted infections, smoking, and contraception use. She reports having regular menstrual cycles and trying to conceive with her husband for 18 months without success until now.

The patient reports that the previous week she took a home pregnancy test that was positive; she endorses having dark brown spotting for the past 2 days but denies pain. Based on the date of her last menstrual period, gestational age is estimated to be 5 weeks and 1 day. Her human chorionic gonadotropin (hCG) level is 1,670 mIU/mL. Transvaginal ultrasonography demonstrates a normal uterus with an endometrial thickness of 10 mm, no evidence of an intrauterine pregnancy (IUP), normal adnexa bilaterally, and scant free fluid in the pelvis.

Identifying and evaluating pregnancy of unknown location

A pregnancy of unknown location (PUL) is defined by a positive serum hCG level in the absence of a visualized IUP or ectopic pregnancy (EP) by pelvic ultrasonography.

Because of variations in screening tools and clinical practices between institutions and care settings (for example, EDs versus specialized outpatient offices), the incidence of PUL is difficult to capture. In specialized early pregnancy clinics, the rate is 8% to 10%, whereas in the ED setting, the PUL rate has been reported to be as high as 42%.^1-6 While approximately 98% to 99% of all pregnancies are intrauterine, only 30% of PULs will continue to develop as viable ongoing intrauterine gestations.^7-9 The remainder are revealed as failing IUPs or EPs. To counsel patients, set expectations, and triage to appropriate management, it is critical to diagnose pregnancy location as efficiently as possible.

Ectopic pregnancy

Ectopic pregnancies represent only 1% to 2% of conceptions (both spontaneous and through assisted reproduction) and occur most commonly in the fallopian tube, although EPs also can implant in the cornua of the uterus, the cervix, cesarean scar, and more rarely on the ovary or abdominal viscera.^10,11 Least common, heterotopic pregnancies—in which an IUP coexists with an EP—occur in 1 in 4,000 to 30,000 pregnancies, more commonly in women who used assisted reproduction.¹¹

Major risk factors for EP include a history of tubal surgery, sexually transmitted infections (particularly Chlamydia trachomatis), pelvic inflammatory disease, conception with an intrauterine device in situ, and a history of prior EP or tubal surgery, particularly prior tubal ligation; minor risk factors include a history of infertility (excluding known tubal factor infertility) or smoking (in a dose-dependent manner).^11,12 The concern for an EP is heightened in patients with these risk factors.

Because of the possibility of rupture and life-threatening hemorrhage, EP carries a risk of significant morbidity and mortality.¹³ Ruptured EPs account for approximately 2.7% of all maternal deaths each year.¹⁴ When diagnosed sufficiently early in a stable patient, most EPs can be managed medically with methotrexate, a folic acid antagonist.¹⁵ Ectopic pregnancies also may be managed surgically, and emergency surgery is indicated in women with evidence of EP rupture and intraperitoneal bleeding.

Continue to: Intrauterine pregnancy...

Intrauterine pregnancy

While excluding EP is critical, it is equally important to diagnose an IUP as expeditiously as possible to avoid inadvertent, destructive intervention. Diagnosis and management of a PUL can involve endometrial aspiration, which would interrupt an IUP and should be avoided until the possibility of a viable IUP has been eliminated in desired pregnancies. The inadvertent administration of methotrexate, a known teratogen, to a patient with an undiagnosed viable IUP can result in miscarriage, elective termination, or a live-born infant with significant malformations, all of which expose the administering physician to malpractice litigation.^16,17

In desired pregnancies, it is essential to differentiate between a viable IUP, a nonviable IUP, and an EP to guide appropriate management and ensure patient safety, whereas exclusion of EP is the priority in undesired pregnancies.

Tools for diagnosing pregnancy location

For diagnosing pregnancy location, serial hCG measurement, transvaginal pelvic ultrasonography, and outpatient endometrial aspiration are all relevant clinical tools. Pregnancy location can be diagnosed with either direct visualization of an IUP or EP by ultrasonography or with confirmed pathology (chorionic villi or trophoblast cells) from endometrial aspiration (FIGURE). A decline in hCG to an undetectable level following endometrial aspiration also is considered sufficient to diagnose a failed IUP, even in the absence of a confirmatory ultrasonography.

Trending hCG values

In stable patients with PUL, serum hCG levels are commonly measured at 2-day intervals, ideally for a minimum of 3 values. Conventional wisdom dictates that in viable IUPs, the hCG level should roughly double every 2 days. However, more recent data suggest that the threshold for minimum expected hCG rise for an ongoing IUP should be far lower when the pregnancy is desired.¹⁸ A less conservative cutoff can be considered when a pregnancy is not desired.

In a multisite cohort study of 1,005 women with PUL, a minimum hCG rise of 35% in 2 days captured the majority of IUPs, with a negative predictive value of 97.2% for IUP.¹⁹ Of note, although the cutoff of 35% was selected to reduce the risk of misdiagnosing an IUP as an EP, 7.7% of IUPs (and 16.8% of EPs) were still misclassified, showing that hCG trends must be interpreted in the context of other clinical data, including ultrasonography findings and patient symptoms and history.

A follow-up study demonstrated that hCG rises are lower (but still within this normal range) when the initial hCG value is higher, particularly greater than 3,000 mIU/mL.²⁰

Studies show that the rate of spontaneous hCG decline in failing IUPs ranges from 12% to 47% in 2 days, falling more rapidly from higher starting hCG values.^19,21 In a retrospective review of 443 women with spontaneously resolving PUL (presumed to be failing IUPs), the minimum 2-day decline in hCG was 35%.²² Any spontaneous hCG decline less than 35% in 2 days in a PUL should raise physician concern for EP.

Conversely, EPs do not demonstrate predictable hCG trends and can mimic the hCG trends of viable or failing IUPs. Although typically half of EPs present with an increasing hCG value and half present with a decreasing hCG value, the majority (71%) demonstrate a slower rate of change than either a viable IUP or a miscarriage.¹¹ This slower change (plateau) should heighten the clinician’s suspicion for an EP.

Continue to: Progesterone levels...

Progesterone levels

A progesterone level often is used to attempt to determine pregnancy viability in women who are not receiving progesterone supplementation, although it ultimately has limited utility. While far less sensitive than an hCG value trend, a serum progesterone level of less than 5 to 10 ng/mL is a rough marker of nonviable pregnancy.²³

In a large meta-analysis of women with pain and bleeding, 96.8% of pregnancies with a single progesterone level of less than 10 ng/mL were nonviable.²³ When an inconclusive ultrasonography was documented in addition to symptoms of pain and bleeding, 99.2% of pregnancies with a progesterone level of less than 3.2 to 6 ng/mL were nonviable.

Progesterone’s usefulness in assessing for a PUL is limited: While progesterone levels may indicate nonviability, they provide no indication of pregnancy location (intrauterine or ectopic).

Alternative serologic markers

Various other reproductive and pregnancy-related hormones have been investigated for use in the diagnosis of pregnancy location in PULs, including activin A, inhibin A, pregnancy-associated plasma protein A (PAPP-A), placental-like growth factor, vascular endothelial growth factor, follistatin, and various microRNAs.^24,25 While research into these biomarkers is ongoing, none have been studied in prospective trials, and they are not for use in current clinical care.

Pelvic ultrasonography

Pelvic ultrasonography is a crucial part of PUL assessment. Transvaginal ultrasonography should be interpreted in the context of the estimated gestational age of the pregnancy and serial hCG values, if available; the patient’s symptoms; and the sensitivity of the ultrasonography equipment, which also may be affected by variables that can reduce visualization, such as uterine fibroids and obesity.

The “discriminatory zone” refers to the hCG value above which an IUP should be visualized by ultrasonography. Generally, with an hCG value of 1,500 to 2,000 mIU/mL or greater, an IUP is expected to be seen with transvaginal sonography.^3,26 Many exceptions to the discriminatory zone have been reported, however, including multiple pregnancies, which will have a higher hCG value at an earlier gestational age. Even in singleton pregnancies, viable IUPs have been documented as developing from PULs with an elevated initial hCG value as high as 4,300 mIU/mL.²⁷ The discriminatory zone may vary among clinical hCG assays, and it also is affected by the quality and modernity of the ultrasonography equipment as well as by the ultrasonography operator’s experience and skill.^28,29

The estimated gestational age, based on either the last menstrual period or assisted reproduction procedure, provides a helpful data point to guide expectations for ultrasonography findings.³⁰ Using transvaginal ultrasonography in a normally progressing IUP, a gestational sac—typically measuring 2 to 3 mm—should be visualized at 5 weeks.^15,30 At approximately 5.5 weeks, a yolk sac measuring 3 to 5 mm should appear. At 6 weeks, an embryo with cardiac activity should be visualized.

In a pregnancy reliably dated beyond 5 weeks, the lack of an intrauterine gestational sac is suspicious for, but not diagnostic of, an EP. Conversely, the visualization of a gestational sac alone (without a yolk sac) is insufficient to definitively exclude an EP, since a small fluid collection in the endometrium (a “pseudosac”) can convincingly mimic the appearance of a gestational sac, and a follow-up ultrasonography should be performed in such cases.

Among patients without ultrasonographic evidence of an IUP, endometrial thickness has been posited as a way to differentiate between IUP and EP.^31,32 Evidence suggests that an endometrial stripe of at least 8 to 10 mm may be somewhat predictive of an IUP, while endometrial thickness below 8 mm is more concerning for EP. This clinical variable, however, has been shown repeatedly to lack sufficient sensitivity and specificity for IUP and should be considered only within the entire clinical context.

Continue to: Endometrial aspiration...

Endometrial aspiration

A persistently abnormal hCG trend and an ultrasonography without evidence of an IUP—particularly with an hCG value above the discriminatory zone and/or with reliable pregnancy dating beyond 5 to 6 weeks—is highly concerning for either a failing IUP or an EP. Once a viable desired IUP is excluded beyond reasonable doubt through these measures, endometrial aspiration to determine pregnancy location is a reasonable next step in PUL management.

Endometrial aspiration can identify a failing IUP by detection of trophoblasts or chorionic villi on pathology and/or by a decline of at least 15% in hCG, measured on the day of endometrial aspiration and again the following day. Endometrial aspiration is effective even in clinical care settings that do not have rapid pathologic analysis available, as hCG measurement before and within 24 hours after the procedure still can be performed.

Vacuum aspiration (electric or manual) in an operating room or office setting is an effective tool for diagnosing pregnancy location.^33,34 The use of an endometrial Pipelle for endometrial sampling (typically used for an office endometrial biopsy to diagnose hyperplasia or malignancy) is insufficient for determining pregnancy location.³⁵ For all patients managed with this protocol, the hCG value ideally should be followed until it is undetectable, regardless of whether an EP or failing IUP was diagnosed. In rare cases, an EP may be diagnosed by a late plateau in hCG values, following an initial decline consistent with a failing IUP.

Utility for diagnosis. Retrospective studies in patients with PUL following in vitro fertilization have established the utility of outpatient endometrial aspiration with a Karman cannula, followed by a repeat hCG measurement on the day after the procedure.^34,36 These data demonstrate that between 42% and 69% of women were ultimately diagnosed with a failed IUP following endometrial aspiration, thereby sparing them unnecessary exposure to methotrexate.

A decline in hCG levels of at least 15% within 24 hours after the procedure indicates that a failed IUP is the most likely diagnosis and further intervention is not indicated (although falling hCG values should be monitored for confirmation); confirmatory pathology with chorionic villi or trophoblasts was present in less than half of these women and is not necessary to diagnose a failed IUP.³⁶ Women diagnosed with a failed IUP after endometrial aspiration also benefitted from a shorter time to resolution of the nonviable pregnancy by approximately 2 weeks.³⁶

Despite the efficacy of endometrial aspiration for the diagnosis of pregnancy location, recent data show that physicians have highly variable approaches to PUL with an hCG plateaued above the discriminatory zone: One-third would first perform endometrial aspiration, while one-third would give methotrexate without further diagnostics.³⁷ Academic physicians were 4 times more likely to recommend endometrial aspiration.³⁷

Presumed EP. Following endometrial aspiration, if pathology does not confirm an intrauterine gestation and the hCG fails to decline by at least 15%, the diagnosis of a presumed EP is made.

For stable patients with neither evidence of intra-abdominal bleeding nor contraindications to methotrexate (such as blood dyscrasias, hepatic or renal insufficiency, active pulmonary or peptic ulcer disease, breastfeeding, or a known intolerance to the medication), methotrexate is recommended for medical management.²⁶ Following screening blood work that includes a complete blood count and liver function and renal function tests, the typical methotrexate dose is 50 mg/m² of body surface area. The single-dose regimen entails checking hCG on the day of methotrexate administration and again on days 4 and 7 thereafter. A minimum decline in hCG of 15% between days 4 and 7 indicates successful treatment; if the hCG decline is below 15%, the patient should receive an additional dose of methotrexate.

There are several published alternative regimens for methotrexate administration, including 2-dose and multidose regimens; the 2-dose protocol (2 doses within 7 days) may be more effective in women with higher hCG (> 3,000 mIU/mL) or known adnexal mass.^26,38

Continue to: Contraindications to methotrexate...

Contraindications to methotrexate. In addition to strict medical contraindications to methotrexate, relative contraindications that indicate a higher risk of methotrexate failure include the presence of fetal cardiac activity, EP mass greater than 4 cm, and serum hCG above 5,000 mIU/mL.²⁶ Because of the potential risk of tubal rupture during medical management, relative contraindications also include patient inability to follow up as an outpatient and patient refusal of blood transfusion.²⁶ Patients with contraindications to methotrexate, hemodynamic instability, ultrasonographic or clinical evidence of EP rupture, or those electing for surgical management may be managed with laparoscopy.¹¹ Discussion of surgical management of EP is beyond the scope of this article.

Follow the hCG level. In patients with a failing IUP or an EP treated with methotrexate or salpingostomy, the hCG level should always be followed until it is negative, usually by weekly measurements once the diagnosis is made. In some cases, the hCG level may plateau after an initial decline, alerting the clinician to failed treatment for a known EP or the need for recategorization of a failed IUP as an EP.

CASE Concluded

The patient’s second and third hCG measurements at 2-day intervals were 1,903 mIU/mL (14% rise) and 2,264 mIU/mL (16% rise). At that point, a repeat transvaginal ultrasonography showed no IUP, adnexal mass, or free fluid. The patient was counseled for outpatient endometrial aspiration, which was performed using manual vacuum aspiration. The serum hCG level on the morning of the procedure was 2,420 mIU/mL. On postprocedure day 1, the serum hCG level fell to 1,615 mIU/mL, a 33% decline. The patient was counseled that this decline in hCG indicated a failing IUP. The final pathologic analysis was returned 3 days later, showing no evidence of trophoblasts and chorionic villi. Regardless, the diagnosis of failing IUP remained given the rapid hCG decline; the tissue from the disrupted failing IUP was likely very scant or simply not drawn into the cannula. Serum hCG levels repeated at weekly intervals revealed ongoing decline, and after 4 weeks, the serum hCG was negative.

In summary

For women diagnosed with PUL, the primary goal is to distinguish an IUP from an EP to reduce the risk of EP rupture through expeditious diagnosis and treatment. In women for whom the pregnancy is desired, distinguishing a viable IUP from a nonviable IUP or an EP is the more specific goal to avoid intervention on a viable IUP (with methotrexate or endometrial aspiration). In women with abnormal hCG trends and indeterminate ultrasonography results (particularly with a serum hCG above the discriminatory zone), outpatient endometrial aspiration is a highly effective way to determine pregnancy location, which dictates further treatment. ●

Generally, with an hCG value of 1,500 to 2,000 mIU/mL or greater, an IUP is expected to be seen with transvaginal sonography.^3,26 Many exceptions to the discriminatory zone have been reported, however, including multiple pregnancies, which will have a higher hCG value at an earlier gestational age. Even in singleton pregnancies, viable IUPs have been documented as developing from PULs with an elevated initial hCG value as high as 4,300 mIU/mL.²⁷ The discriminatory zone may vary among clinical hCG assays, and it also is affected by the quality and modernity of the ultrasonography equipment as well as by the ultrasonography operator’s experience and skill.^28,29

The estimated gestational age, based on either the last menstrual period or assisted reproduction procedure, provides a helpful data point to guide expectations for ultrasonography findings.³⁰ Using transvaginal ultrasonography in a normally progressing IUP, a gestational sac—typically measuring 2 to 3 mm—should be visualized at 5 weeks.^15,30 At approximately 5.5 weeks, a yolk sac measuring 3 to 5 mm should appear. At 6 weeks, an embryo with cardiac activity should be visualized.

In a pregnancy reliably dated beyond 5 weeks, the lack of an intrauterine gestational sac is suspicious for, but not diagnostic of, an EP. Conversely, the visualization of a gestational sac alone (without a yolk sac) is insufficient to definitively exclude an EP, since a small fluid collection in the endometrium (a “pseudosac”) can convincingly mimic the appearance of a gestational sac, and a follow-up ultrasonography should be performed in such cases.

Among patients without ultrasonographic evidence of an IUP, endometrial thickness has been posited as a way to differentiate between IUP and EP.^31,32 Evidence suggests that an endometrial stripe of at least 8 to 10 mm may be somewhat predictive of an IUP, while endometrial thickness below 8 mm is more concerning for EP. This clinical variable, however, has been shown repeatedly to lack sufficient sensitivity and specificity for IUP and should be considered only within the entire clinical context.

Endometrial aspiration

A persistently abnormal hCG trend and an ultrasonography without evidence of an IUP—particularly with an hCG value above the discriminatory zone and/or with reliable pregnancy dating beyond 5 to 6 weeks—is highly concerning for either a failing IUP or an EP. Once a viable desired IUP is excluded beyond reasonable doubt through these measures, endometrial aspiration to determine pregnancy location is a reasonable next step in PUL management.

Endometrial aspiration can identify a failing IUP by detection of trophoblasts or chorionic villi on pathology and/or by a decline of at least 15% in hCG, measured on the day of endometrial aspiration and again the following day. Endometrial aspiration is effective even in clinical care settings that do not have rapid pathologic analysis available, as hCG measurement before and within 24 hours after the procedure still can be performed.

Vacuum aspiration (electric or manual) in an operating room or office setting is an effective tool for diagnosing pregnancy location.^33,34 The use of an endometrial Pipelle for endometrial sampling (typically used for an office endometrial biopsy to diagnose hyperplasia or malignancy) is insufficient for determining pregnancy location.³⁵ For all patients managed with this protocol, the hCG value ideally should be followed until it is undetectable, regardless of whether an EP or failing IUP was diagnosed. In rare cases, an EP may be diagnosed by a late plateau in hCG values, following an initial decline consistent with a failing IUP.

Utility for diagnosis. Retrospective studies in patients with PUL following in vitro fertilization have established the utility of outpatient endometrial aspiration with a Karman cannula, followed by a repeat hCG measurement on the day after the procedure.^34,36 These data demonstrate that between 42% and 69% of women were ultimately diagnosed with a failed IUP following endometrial aspiration, thereby sparing them unnecessary exposure to methotrexate.

A decline in hCG levels of at least 15% within 24 hours after the procedure indicates that a failed IUP is the most likely diagnosis and further intervention is not indicated (although falling hCG values should be monitored for confirmation); confirmatory pathology with chorionic villi or trophoblasts was present in less than half of these women and is not necessary to diagnose a failed IUP.³⁶ Women diagnosed with a failed IUP after endometrial aspiration also benefitted from a shorter time to resolution of the nonviable pregnancy by approximately 2 weeks.³⁶

Despite the efficacy of endometrial aspiration for the diagnosis of pregnancy location, recent data show that physicians have highly variable approaches to PUL with an hCG plateaued above the discriminatory zone: One-third would first perform endometrial aspiration, while one-third would give methotrexate without further diagnostics.³⁷ Academic physicians were 4 times more likely to recommend endometrial aspiration.³⁷

Presumed EP. Following endometrial aspiration, if pathology does not confirm an intrauterine gestation and the hCG fails to decline by at least 15%, the diagnosis of a presumed EP is made.

For stable patients with neither evidence of intra-abdominal bleeding nor contraindications to methotrexate (such as blood dyscrasias, hepatic or renal insufficiency, active pulmonary or peptic ulcer disease, breastfeeding, or a known intolerance to the medication), methotrexate is recommended for medical management.²⁶ Following screening blood work that includes a complete blood count and liver function and renal function tests, the typical methotrexate dose is 50 mg/m² of body surface area. The single-dose regimen entails checking hCG on the day of methotrexate administration and again on days 4 and 7 thereafter. A minimum decline in hCG of 15% between days 4 and 7 indicates successful treatment; if the hCG decline is below 15%, the patient should receive an additional dose of methotrexate.

There are several published alternative regimens for methotrexate administration, including 2-dose and multidose regimens; the 2-dose protocol (2 doses within 7 days) may be more effective in women with higher hCG (> 3,000 mIU/mL) or known adnexal mass.^26,38

Continue to: Contraindications to methotrexate...

Contraindications to methotrexate. In addition to strict medical contraindications to methotrexate, relative contraindications that indicate a higher risk of methotrexate failure include the presence of fetal cardiac activity, EP mass greater than 4 cm, and serum hCG above 5,000 mIU/mL.²⁶ Because of the potential risk of tubal rupture during medical management, relative contraindications also include patient inability to follow up as an outpatient and patient refusal of blood transfusion.²⁶ Patients with contraindications to methotrexate, hemodynamic instability, ultrasonographic or clinical evidence of EP rupture, or those electing for surgical management may be managed with laparoscopy.¹¹ Discussion of surgical management of EP is beyond the scope of this article.

Follow the hCG level. In patients with a failing IUP or an EP treated with methotrexate or salpingostomy, the hCG level should always be followed until it is negative, usually by weekly measurements once the diagnosis is made. In some cases, the hCG level may plateau after an initial decline, alerting the clinician to failed treatment for a known EP or the need for recategorization of a failed IUP as an EP.

CASE Concluded

The patient’s second and third hCG measurements at 2-day intervals were 1,903 mIU/mL (14% rise) and 2,264 mIU/mL (16% rise). At that point, a repeat transvaginal ultrasonography showed no IUP, adnexal mass, or free fluid. The patient was counseled for outpatient endometrial aspiration, which was performed using manual vacuum aspiration. The serum hCG level on the morning of the procedure was 2,420 mIU/mL. On postprocedure day 1, the serum hCG level fell to 1,615 mIU/mL, a 33% decline. The patient was counseled that this decline in hCG indicated a failing IUP. The final pathologic analysis was returned 3 days later, showing no evidence of trophoblasts and chorionic villi. Regardless, the diagnosis of failing IUP remained given the rapid hCG decline; the tissue from the disrupted failing IUP was likely very scant or simply not drawn into the cannula. Serum hCG levels repeated at weekly intervals revealed ongoing decline, and after 4 weeks, the serum hCG was negative.

In summary

For women diagnosed with PUL, the primary goal is to distinguish an IUP from an EP to reduce the risk of EP rupture through expeditious diagnosis and treatment. In women for whom the pregnancy is desired, distinguishing a viable IUP from a nonviable IUP or an EP is the more specific goal to avoid intervention on a viable IUP (with methotrexate or endometrial aspiration). In women with abnormal hCG trends and indeterminate ultrasonography results (particularly with a serum hCG above the discriminatory zone), outpatient endometrial aspiration is a highly effective way to determine pregnancy location, which dictates further treatment. ●

CASE Woman with bleeding in early pregnancy

A 31-year-old woman (G1P0) presents to the local emergency department (ED) due to bleeding in pregnancy. She reports a prior open appendectomy for ruptured appendix; she denies a history of sexually transmitted infections, smoking, and contraception use. She reports having regular menstrual cycles and trying to conceive with her husband for 18 months without success until now.

The patient reports that the previous week she took a home pregnancy test that was positive; she endorses having dark brown spotting for the past 2 days but denies pain. Based on the date of her last menstrual period, gestational age is estimated to be 5 weeks and 1 day. Her human chorionic gonadotropin (hCG) level is 1,670 mIU/mL. Transvaginal ultrasonography demonstrates a normal uterus with an endometrial thickness of 10 mm, no evidence of an intrauterine pregnancy (IUP), normal adnexa bilaterally, and scant free fluid in the pelvis.

Identifying and evaluating pregnancy of unknown location

A pregnancy of unknown location (PUL) is defined by a positive serum hCG level in the absence of a visualized IUP or ectopic pregnancy (EP) by pelvic ultrasonography.

Because of variations in screening tools and clinical practices between institutions and care settings (for example, EDs versus specialized outpatient offices), the incidence of PUL is difficult to capture. In specialized early pregnancy clinics, the rate is 8% to 10%, whereas in the ED setting, the PUL rate has been reported to be as high as 42%.^1-6 While approximately 98% to 99% of all pregnancies are intrauterine, only 30% of PULs will continue to develop as viable ongoing intrauterine gestations.^7-9 The remainder are revealed as failing IUPs or EPs. To counsel patients, set expectations, and triage to appropriate management, it is critical to diagnose pregnancy location as efficiently as possible.

Ectopic pregnancy

Ectopic pregnancies represent only 1% to 2% of conceptions (both spontaneous and through assisted reproduction) and occur most commonly in the fallopian tube, although EPs also can implant in the cornua of the uterus, the cervix, cesarean scar, and more rarely on the ovary or abdominal viscera.^10,11 Least common, heterotopic pregnancies—in which an IUP coexists with an EP—occur in 1 in 4,000 to 30,000 pregnancies, more commonly in women who used assisted reproduction.¹¹

Major risk factors for EP include a history of tubal surgery, sexually transmitted infections (particularly Chlamydia trachomatis), pelvic inflammatory disease, conception with an intrauterine device in situ, and a history of prior EP or tubal surgery, particularly prior tubal ligation; minor risk factors include a history of infertility (excluding known tubal factor infertility) or smoking (in a dose-dependent manner).^11,12 The concern for an EP is heightened in patients with these risk factors.

Because of the possibility of rupture and life-threatening hemorrhage, EP carries a risk of significant morbidity and mortality.¹³ Ruptured EPs account for approximately 2.7% of all maternal deaths each year.¹⁴ When diagnosed sufficiently early in a stable patient, most EPs can be managed medically with methotrexate, a folic acid antagonist.¹⁵ Ectopic pregnancies also may be managed surgically, and emergency surgery is indicated in women with evidence of EP rupture and intraperitoneal bleeding.

Continue to: Intrauterine pregnancy...

Intrauterine pregnancy

While excluding EP is critical, it is equally important to diagnose an IUP as expeditiously as possible to avoid inadvertent, destructive intervention. Diagnosis and management of a PUL can involve endometrial aspiration, which would interrupt an IUP and should be avoided until the possibility of a viable IUP has been eliminated in desired pregnancies. The inadvertent administration of methotrexate, a known teratogen, to a patient with an undiagnosed viable IUP can result in miscarriage, elective termination, or a live-born infant with significant malformations, all of which expose the administering physician to malpractice litigation.^16,17

In desired pregnancies, it is essential to differentiate between a viable IUP, a nonviable IUP, and an EP to guide appropriate management and ensure patient safety, whereas exclusion of EP is the priority in undesired pregnancies.

Tools for diagnosing pregnancy location

For diagnosing pregnancy location, serial hCG measurement, transvaginal pelvic ultrasonography, and outpatient endometrial aspiration are all relevant clinical tools. Pregnancy location can be diagnosed with either direct visualization of an IUP or EP by ultrasonography or with confirmed pathology (chorionic villi or trophoblast cells) from endometrial aspiration (FIGURE). A decline in hCG to an undetectable level following endometrial aspiration also is considered sufficient to diagnose a failed IUP, even in the absence of a confirmatory ultrasonography.

Trending hCG values

In stable patients with PUL, serum hCG levels are commonly measured at 2-day intervals, ideally for a minimum of 3 values. Conventional wisdom dictates that in viable IUPs, the hCG level should roughly double every 2 days. However, more recent data suggest that the threshold for minimum expected hCG rise for an ongoing IUP should be far lower when the pregnancy is desired.¹⁸ A less conservative cutoff can be considered when a pregnancy is not desired.

In a multisite cohort study of 1,005 women with PUL, a minimum hCG rise of 35% in 2 days captured the majority of IUPs, with a negative predictive value of 97.2% for IUP.¹⁹ Of note, although the cutoff of 35% was selected to reduce the risk of misdiagnosing an IUP as an EP, 7.7% of IUPs (and 16.8% of EPs) were still misclassified, showing that hCG trends must be interpreted in the context of other clinical data, including ultrasonography findings and patient symptoms and history.

A follow-up study demonstrated that hCG rises are lower (but still within this normal range) when the initial hCG value is higher, particularly greater than 3,000 mIU/mL.²⁰

Studies show that the rate of spontaneous hCG decline in failing IUPs ranges from 12% to 47% in 2 days, falling more rapidly from higher starting hCG values.^19,21 In a retrospective review of 443 women with spontaneously resolving PUL (presumed to be failing IUPs), the minimum 2-day decline in hCG was 35%.²² Any spontaneous hCG decline less than 35% in 2 days in a PUL should raise physician concern for EP.

Conversely, EPs do not demonstrate predictable hCG trends and can mimic the hCG trends of viable or failing IUPs. Although typically half of EPs present with an increasing hCG value and half present with a decreasing hCG value, the majority (71%) demonstrate a slower rate of change than either a viable IUP or a miscarriage.¹¹ This slower change (plateau) should heighten the clinician’s suspicion for an EP.

Continue to: Progesterone levels...

Progesterone levels

A progesterone level often is used to attempt to determine pregnancy viability in women who are not receiving progesterone supplementation, although it ultimately has limited utility. While far less sensitive than an hCG value trend, a serum progesterone level of less than 5 to 10 ng/mL is a rough marker of nonviable pregnancy.²³

In a large meta-analysis of women with pain and bleeding, 96.8% of pregnancies with a single progesterone level of less than 10 ng/mL were nonviable.²³ When an inconclusive ultrasonography was documented in addition to symptoms of pain and bleeding, 99.2% of pregnancies with a progesterone level of less than 3.2 to 6 ng/mL were nonviable.

Progesterone’s usefulness in assessing for a PUL is limited: While progesterone levels may indicate nonviability, they provide no indication of pregnancy location (intrauterine or ectopic).

Alternative serologic markers

Various other reproductive and pregnancy-related hormones have been investigated for use in the diagnosis of pregnancy location in PULs, including activin A, inhibin A, pregnancy-associated plasma protein A (PAPP-A), placental-like growth factor, vascular endothelial growth factor, follistatin, and various microRNAs.^24,25 While research into these biomarkers is ongoing, none have been studied in prospective trials, and they are not for use in current clinical care.

Pelvic ultrasonography

Pelvic ultrasonography is a crucial part of PUL assessment. Transvaginal ultrasonography should be interpreted in the context of the estimated gestational age of the pregnancy and serial hCG values, if available; the patient’s symptoms; and the sensitivity of the ultrasonography equipment, which also may be affected by variables that can reduce visualization, such as uterine fibroids and obesity.

The “discriminatory zone” refers to the hCG value above which an IUP should be visualized by ultrasonography. Generally, with an hCG value of 1,500 to 2,000 mIU/mL or greater, an IUP is expected to be seen with transvaginal sonography.^3,26 Many exceptions to the discriminatory zone have been reported, however, including multiple pregnancies, which will have a higher hCG value at an earlier gestational age. Even in singleton pregnancies, viable IUPs have been documented as developing from PULs with an elevated initial hCG value as high as 4,300 mIU/mL.²⁷ The discriminatory zone may vary among clinical hCG assays, and it also is affected by the quality and modernity of the ultrasonography equipment as well as by the ultrasonography operator’s experience and skill.^28,29

The estimated gestational age, based on either the last menstrual period or assisted reproduction procedure, provides a helpful data point to guide expectations for ultrasonography findings.³⁰ Using transvaginal ultrasonography in a normally progressing IUP, a gestational sac—typically measuring 2 to 3 mm—should be visualized at 5 weeks.^15,30 At approximately 5.5 weeks, a yolk sac measuring 3 to 5 mm should appear. At 6 weeks, an embryo with cardiac activity should be visualized.

In a pregnancy reliably dated beyond 5 weeks, the lack of an intrauterine gestational sac is suspicious for, but not diagnostic of, an EP.

During the pandemic, physicians have raced to set up or expand telemedicine, uncovering both advantages and shortcomings. Now experts have developed a checklist of more than a dozen ideas to facilitate effective virtual visits with older adults.

Although many of the suggestions, published online in Annals of Internal Medicine, are useful for all patients, Carrie Nieman, MD, MPH, and Esther S. Oh, MD, PhD, developed the list with older patients in mind.

“I have a number of patients into their 90s and with hearing loss, and we have had very successful video-based telemedicine visits,” Dr. Nieman, with the Cochlear Center for Hearing and Public Health at Johns Hopkins Bloomberg School of Public Health in Baltimore said in an interview. “Age should not be considered synonymous with inability or unwillingness to use technology.”

Their recommendations included the following:

• Assume some degree of hearing loss, which affects about two-thirds of adults aged 70 years and older.
• Ask patients to wear headphones or a headset or confirm that they are wearing their hearing aids and are in a quiet location.
• Use a headset.
• When possible, use video and have the camera focused on your face.
• Use captioning when available and provide a written summary of key points and instructions.
• Pay attention to cues, such as nodding along or looking to a loved one, that suggest a patient may not be following the conversation.

“If cognitive impairment is suspected, several screening tools can be used over the telephone to identify individuals who may need more comprehensive, in-person assessment,” wrote Dr. Nieman and Dr. Oh, who is with the division of geriatric medicine and gerontology at Johns Hopkins University School of Medicine. For example, data suggest that a modified version of the Mini–Mental State Examination and the Delirium Symptom Interview could be useful tools. “A formal diagnosis of dementia is not recommended solely based on a telephone-based cognitive screening,” however, Dr. Nieman and Dr. Oh said.

For patients with hearing loss, video visits avoid a current limitation of in-person visits: face masks that hinder patients’ ability to read lips and other visual cues. “For many of us, we rely on these types of cues more than we think,” Dr. Nieman said in an interview.

“When you have doubts about whether you and your patient are on the same page, check in with the patient,” Dr. Nieman said. “When appropriate, having a loved one or a care partner join an encounter, or at least a portion of the encounter, can be helpful to both the patient and the provider.”

Many older patients unprepared

Millions of older patients may not have been ready for the rapid shift to telemedicine brought on by COVID-19, a recent study in JAMA Internal Medicine suggests. Between 32% and 38% of older adults in the United States may not have been ready for video visits, largely because of inexperience with technology. Approximately 20% could have difficulty with telephone visits because of problems hearing or communicating or because of dementia.

Kenneth Lam, MD, of the division of geriatrics at the University of California, San Francisco (UCSF), and colleagues arrived at these estimates after analyzing data from more than 4,500 participants in the National Health and Aging Trends Study that was conducted in 2018. The study is nationally representative of Medicare beneficiaries 65 years or older.

The aim of the study “was to call attention to what clinicians were already experiencing on the front lines,” Dr. Lam said. In an interview, he imagined two scenarios based on his colleagues’ accounts of telemedicine visits.

In one case, a 72-year-old woman logs into Zoom Health on her iPad without any trouble. “She explains she just pushed on the URL and everything loaded up and you have a great visit,” Dr. Lam said. “This is likely to be the case for over 50% of the older people you see; I share this picture to combat ageism, which is, truthfully, just inaccurate stereotyping of older people and gets in the way of actionable, data-driven policies.

“However, for around one in three older adults (and closer to three out of every four of those over the age of 85), you will book an appointment and they will say they don’t have an email address or a computer or know how to go online,” Dr. Lam said. “Or suppose they decide to try it out. ... Come appointment time, you log on and they pick up, but now their sound doesn’t work. They keep saying they can see you but they can’t hear you. ... They accidentally hang up. You place another call, and they ask if you can switch to a phone conversation instead.”

By phone, the physician can address concerns about the patient’s blood pressure, which the patient has been measuring daily. “But when it comes to looking at the swelling in their legs, you’re out of luck, and you’ve been on this call for 45 minutes,” Dr. Lam said.

Have a backup plan

Making sure patients are prepared and having a backup plan can help, said Kaitlin Willham, MD, of UCSF and the San Francisco VA Medical Center.

She says older patients fall into a wide range of categories in terms of skills and access to equipment. Knowing which category a patient falls into and having relevant support available to troubleshoot are important.

During the pandemic, Dr. Willham has conducted many more telemedicine visits with patients who are at their place of residence, whether a private home or a residential care facility. “Even outside of the current crisis, there are benefits to home video visits,” Dr. Willham said. “A home video visit can provide a more holistic view of the patient than an office visit, allowing the clinician to see how the person lives, what they might be challenged by. It allows the clinician to identify areas of intervention and, if there is a care partner, involving that person in the plan. If the visit starts without major technical or communication barriers, they are generally very well received.”

For patients with problems hearing for whom headphones or amplification devices are not available, “using a landline for the audio portion of the visit can help, as can having someone with the patient reiterate what was said,” Dr. Willham suggested. “Many video platforms also enable the clinician to type messages or share a screen with a live document. These options can work well when there is very severe or complete lack of hearing.”

Sometimes an in-person visit is the right way to go, even when technical hurdles can be overcome.

“Although many older adults are willing and able to learn to use telemedicine, an equitable health system should recognize that for some, such as those with dementia and social isolation, in-person visits are already difficult and telemedicine may be impossible,” Dr. Lam and coauthors wrote. “For these patients, clinics and geriatric models of care such as home visits are essential.”

Dr. Nieman, Dr. Oh, and one of Dr. Lam’s coauthors have received funding from the National Institutes of Health. Dr. Oh also has received funding from the Roberts Family Fund. Dr. Nieman serves as a board member of the nonprofit organization Access HEARS and is on the board of trustees of the Hearing Loss Association of America.

For example, data suggest that a modified version of the Mini–Mental State Examination and the Delirium Symptom Interview could be useful tools. “A formal diagnosis of dementia is not recommended solely based on a telephone-based cognitive screening,” however, Dr. Nieman and Dr. Oh said.

For patients with hearing loss, video visits avoid a current limitation of in-person visits: face masks that hinder patients’ ability to read lips and other visual cues. “For many of us, we rely on these types of cues more than we think,” Dr. Nieman said in an interview.

“When you have doubts about whether you and your patient are on the same page, check in with the patient,” Dr. Nieman said. “When appropriate, having a loved one or a care partner join an encounter, or at least a portion of the encounter, can be helpful to both the patient and the provider.”

Many older patients unprepared

Millions of older patients may not have been ready for the rapid shift to telemedicine brought on by COVID-19, a recent study in JAMA Internal Medicine suggests. Between 32% and 38% of older adults in the United States may not have been ready for video visits, largely because of inexperience with technology. Approximately 20% could have difficulty with telephone visits because of problems hearing or communicating or because of dementia.

Kenneth Lam, MD, of the division of geriatrics at the University of California, San Francisco (UCSF), and colleagues arrived at these estimates after analyzing data from more than 4,500 participants in the National Health and Aging Trends Study that was conducted in 2018. The study is nationally representative of Medicare beneficiaries 65 years or older.

The aim of the study “was to call attention to what clinicians were already experiencing on the front lines,” Dr. Lam said. In an interview, he imagined two scenarios based on his colleagues’ accounts of telemedicine visits.

In one case, a 72-year-old woman logs into Zoom Health on her iPad without any trouble. “She explains she just pushed on the URL and everything loaded up and you have a great visit,” Dr. Lam said. “This is likely to be the case for over 50% of the older people you see; I share this picture to combat ageism, which is, truthfully, just inaccurate stereotyping of older people and gets in the way of actionable, data-driven policies.

“However, for around one in three older adults (and closer to three out of every four of those over the age of 85), you will book an appointment and they will say they don’t have an email address or a computer or know how to go online,” Dr. Lam said. “Or suppose they decide to try it out. ... Come appointment time, you log on and they pick up, but now their sound doesn’t work. They keep saying they can see you but they can’t hear you. ... They accidentally hang up. You place another call, and they ask if you can switch to a phone conversation instead.”

By phone, the physician can address concerns about the patient’s blood pressure, which the patient has been measuring daily. “But when it comes to looking at the swelling in their legs, you’re out of luck, and you’ve been on this call for 45 minutes,” Dr. Lam said.

Have a backup plan

Making sure patients are prepared and having a backup plan can help, said Kaitlin Willham, MD, of UCSF and the San Francisco VA Medical Center.

She says older patients fall into a wide range of categories in terms of skills and access to equipment. Knowing which category a patient falls into and having relevant support available to troubleshoot are important.

During the pandemic, Dr. Willham has conducted many more telemedicine visits with patients who are at their place of residence, whether a private home or a residential care facility. “Even outside of the current crisis, there are benefits to home video visits,” Dr. Willham said. “A home video visit can provide a more holistic view of the patient than an office visit, allowing the clinician to see how the person lives, what they might be challenged by. It allows the clinician to identify areas of intervention and, if there is a care partner, involving that person in the plan. If the visit starts without major technical or communication barriers, they are generally very well received.”

For patients with problems hearing for whom headphones or amplification devices are not available, “using a landline for the audio portion of the visit can help, as can having someone with the patient reiterate what was said,” Dr. Willham suggested. “Many video platforms also enable the clinician to type messages or share a screen with a live document. These options can work well when there is very severe or complete lack of hearing.”

Sometimes an in-person visit is the right way to go, even when technical hurdles can be overcome.

“Although many older adults are willing and able to learn to use telemedicine, an equitable health system should recognize that for some, such as those with dementia and social isolation, in-person visits are already difficult and telemedicine may be impossible,” Dr. Lam and coauthors wrote. “For these patients, clinics and geriatric models of care such as home visits are essential.”

Dr. Nieman, Dr. Oh, and one of Dr. Lam’s coauthors have received funding from the National Institutes of Health. Dr. Oh also has received funding from the Roberts Family Fund. Dr. Nieman serves as a board member of the nonprofit organization Access HEARS and is on the board of trustees of the Hearing Loss Association of America.

During the pandemic, physicians have raced to set up or expand telemedicine, uncovering both advantages and shortcomings. Now experts have developed a checklist of more than a dozen ideas to facilitate effective virtual visits with older adults.

Although many of the suggestions, published online in Annals of Internal Medicine, are useful for all patients, Carrie Nieman, MD, MPH, and Esther S. Oh, MD, PhD, developed the list with older patients in mind.

“I have a number of patients into their 90s and with hearing loss, and we have had very successful video-based telemedicine visits,” Dr. Nieman, with the Cochlear Center for Hearing and Public Health at Johns Hopkins Bloomberg School of Public Health in Baltimore said in an interview. “Age should not be considered synonymous with inability or unwillingness to use technology.”

Their recommendations included the following:

• Assume some degree of hearing loss, which affects about two-thirds of adults aged 70 years and older.
• Ask patients to wear headphones or a headset or confirm that they are wearing their hearing aids and are in a quiet location.
• Use a headset.
• When possible, use video and have the camera focused on your face.
• Use captioning when available and provide a written summary of key points and instructions.
• Pay attention to cues, such as nodding along or looking to a loved one, that suggest a patient may not be following the conversation.

“If cognitive impairment is suspected, several screening tools can be used over the telephone to identify individuals who may need more comprehensive, in-person assessment,” wrote Dr. Nieman and Dr. Oh, who is with the division of geriatric medicine and gerontology at Johns Hopkins University School of Medicine.

Shortages of personal protective equipment and medical supplies could persist for years without strategic government intervention, officials from health care and manufacturing industries have predicted.

Liliboas/iStock/Getty Images Plus

Officials said logistical challenges continue 7 months after the coronavirus reached the United States, as the flu season approaches and as some state emergency management agencies prepare for a fall surge in COVID-19 cases.

Although the disarray is not as widespread as it was this spring, hospitals said rolling shortages of supplies range from specialized beds to disposable isolation gowns to thermometers.

“A few weeks ago, we were having a very difficult time getting the sanitary wipes. You just couldn’t get them,” said Bernard Klein, MD, chief executive of Providence Holy Cross Medical Center in Mission Hills, Calif., near Los Angeles. “We actually had to manufacture our own.”

This same dynamic has played out across a number of critical supplies in his hospital. First masks, then isolation gowns and now a specialized bed that allows nurses to turn COVID-19 patients onto their bellies – equipment that helps workers with what can otherwise be a six-person job.

“We’ve seen whole families come to our hospital with COVID, and several members hospitalized at the same time,” said Dr. Klein. “It’s very, very sad.”

Testing supplies ran short as the predominantly Latino community served by Providence Holy Cross was hit hard by COVID, and even as nearby hospitals could process 15-minute tests.

“If we had a more coordinated response with a partnership between the medical field, the government and the private industry, it would help improve the supply chain to the areas that need it most,” Dr. Klein said.

Dr. Klein said he expected to deal with equipment and supply shortages throughout 2021, especially as flu season approaches.

“Most people focus on those N95 respirators,” said Carmela Coyle, CEO of the California Hospital Association, an industry group that represents more than 400 hospitals across one of America’s hardest-hit states.

She said she believed COVID-19-related supply challenges will persist through 2022.

“We have been challenged with shortages of isolation gowns, face shields, which you’re now starting to see in public places. Any one piece that’s in shortage or not available creates risk for patients and for health care workers,” said Ms. Coyle.

At the same time, trade associations representing manufacturers said persuading customers to shift to American suppliers had been difficult.

“I also have industry that’s working only at 10-20% capacity, who can make PPE in our own backyard, but have no orders,” said Kim Glas, CEO of the National Council of Textile Organizations, whose members make reusable cloth gowns.

Manufacturers in her organization have made “hundreds of millions of products,” but, without long-term government contracts, many are apprehensive to invest in the equipment needed to scale up the business and eventually lower prices.

“If there continues to be an upward trajectory of COVID-19 cases, not just in the U.S. but globally, you can see those supply chains breaking down again,” Ms. Glas said. “It is a health care security issue.”

For the past 2 decades, personal protective equipment was supplied to health care institutions in lean supply chains in the same way toilet paper was to grocery stores. Chains between major manufacturers and end users were so efficient, there was no need to stockpile goods.

But in March, the supply chain broke when major Asian PPE exporters embargoed materials or shut down just as demand increased exponentially. Thus, health care institutions were in much the same position as regular grocery shoppers, who were trying to buy great quantities of a product they never needed to stockpile before.

“I am very concerned about long-term PPE shortages for the foreseeable future,” said Susan Bailey, MD, president of the American Medical Association.

“There’s no question the situation is better than it was a couple of months ago,” said Bailey. However, many health care organizations, including her own, have struggled to obtain PPE. Bailey practices at a 10-doctor allergy clinic and was met with a 10,000-mask minimum when they tried to order N95 respirators.

“We have not seen evidence of a long-term strategic plan for the manufacture, acquisition and distribution of PPE” from the government, said Dr. Bailey. “The supply chain needs to be strengthened dramatically, and we need less dependence on foreign goods to manufacture our own PPE in the U.S.”

Some products have now come back to be made in the United States – although factories are not expected to be able to reach demand until mid-2021.

“A lot has been done in the last 6 months. We are largely out of the hole, and we have planted the seeds to render the United States self-sufficient,” said Dave Rousse, president of the Association of the Nonwoven Fabrics Industry.

In 2019, 850 tons of the material used in disposable masks was made in the United States. Around 10,000 tons is expected to be made in 2021, satisfying perhaps 80% of demand. But PPE is a suite of items – including gloves, gowns and face shields – not all of which have seen the same success.

“Thermometers are becoming a real issue,” said Cindy Juhas, chief strategy officer of CME, an American health care product distributor. “They’re expecting even a problem with needles and syringes for the amount of vaccines they have to make.”

Federal government efforts to address the supply chain have foundered. The Federal Emergency Management Agency, in charge of the COVID-19 response, told congressional interviewers in June it had “no involvement” in distributing PPE to hot spots.

Project Airbridge, an initiative headed by Jared Kushner, President Donald Trump’s son-in-law, flew PPE from international suppliers to the U.S. at taxpayer expense but was phased out. And the government has not responded to the AMA’s calls for more distribution data.

Arguably, Dr. Klein is among the best placed to weather such disruptions. He is part of a 51-hospital chain with purchasing power, and among the institutions that distributors prioritize when selling supplies. But tribulations continue even in hospitals, as shortages have pushed buyers to look directly for manufacturers, often through a swamp of companies that have sprung up overnight.

Now distributors are being called upon not just by their traditional customers – hospitals and long-term care homes – but by nearly every segment of society. First responders, schools, clinics and even food businesses are all buying medical equipment now.

“There’s going to be lots of other shortages we haven’t even thought about,” said Ms. Juhas.

Research on COVID-19 as it relates to rheumatic and musculoskeletal diseases (RMDs) is accumulating “at an enormously rapid pace,” but a recent review of the literature suggests that quantity should not be confused with quality.

“We are faced by the worldwide spread of a disease that was nonexistent less than a year ago,” Féline P.B. Kroon, MD, and associates said in Annals of the Rheumatic Diseases. “To date, no robust evidence is available to allow strong conclusions on the effects of COVID-19 in patients with RMDs or whether RMDs or [their] treatment impact incidence of infection or outcomes.”

When it comes to quantity of evidence, “the exponential increase in publications over time is evident,” they said. From Jan. 1, 2019 to June 24, 2020, there were 1,725 hits on PubMed for published reports combining COVID-19 with RMDs and drugs used in RMDs. At the beginning of the year, there were only 135 such publications.

The early start of the search, well before identification of the novel coronavirus in China, was meant to ensure that nothing was missed, so “citations that came up in the first months of 2019 mostly encompass papers about other coronaviruses, such as SARS and MERS,” said Dr. Kroon of Zuyderland Medical Center, Heerlen, the Netherlands, when asked for clarification.

The quality of that evidence, however, is another matter. A majority of publications (60%) are “viewpoints or (narrative) literature reviews, and only a small proportion actually presents original data in the form of case reports or case series (15%), observational cohort studies (10%), or clinical trials (<1%),” the investigators explained.

Very few of the published studies, about 10%, specifically involve COVID-19 and RMDs. Even well-regarded sources such as systematic literature reviews or meta-analyses, “which will undoubtedly appear more frequently in the next few months in response to requests by users who feel overwhelmed by a multitude of data, will not eliminate the internal bias present in individual studies,” Dr. Kroon and associates wrote.

The lack of evidence also brings into question one particular form of guidance: recommendations “issued by groups of the so-called experts and (inter)national societies, such as, among others, American College of Rheumatology and European League Against Rheumatism,” the investigators said.

“The rapid increase in research on COVID-19 is encouraging,” but at the same time it “also poses risks of ‘information overload’ or ‘fake news,’ ” they said. “As researchers and clinicians, it is our responsibility to carefully interpret study results that emerge, even more so in this ‘digital era,’ in which published data can quickly have a large societal impact.”

Research on COVID-19 as it relates to rheumatic and musculoskeletal diseases (RMDs) is accumulating “at an enormously rapid pace,” but a recent review of the literature suggests that quantity should not be confused with quality.

“We are faced by the worldwide spread of a disease that was nonexistent less than a year ago,” Féline P.B. Kroon, MD, and associates said in Annals of the Rheumatic Diseases. “To date, no robust evidence is available to allow strong conclusions on the effects of COVID-19 in patients with RMDs or whether RMDs or [their] treatment impact incidence of infection or outcomes.”

When it comes to quantity of evidence, “the exponential increase in publications over time is evident,” they said. From Jan. 1, 2019 to June 24, 2020, there were 1,725 hits on PubMed for published reports combining COVID-19 with RMDs and drugs used in RMDs. At the beginning of the year, there were only 135 such publications.

The early start of the search, well before identification of the novel coronavirus in China, was meant to ensure that nothing was missed, so “citations that came up in the first months of 2019 mostly encompass papers about other coronaviruses, such as SARS and MERS,” said Dr. Kroon of Zuyderland Medical Center, Heerlen, the Netherlands, when asked for clarification.

The quality of that evidence, however, is another matter. A majority of publications (60%) are “viewpoints or (narrative) literature reviews, and only a small proportion actually presents original data in the form of case reports or case series (15%), observational cohort studies (10%), or clinical trials (<1%),” the investigators explained.

ANSWER

The correct answer is all the above (choice “e”).

DISCUSSION

The differential for round or annular, scaly lesions is lengthy. In addition to all 4 conditions listed above, it includes eczema, basal cell carcinoma, and irritant or contact dermatitis.

With this patient’s history, the diagnosis of fungal infection was not unreasonable. However, the total lack of response to antifungal treatment—along with a negative KOH prep—made that diagnosis questionable at best. Then there was the lack of lymphadenopathy, which would almost certainly have been present with such longstanding infection. Given her country of origin, cutaneous New World leishmaniasis (caused by a protozoan delivered to the patient by an insect vector) was a possibility.

For this patient, skin biopsy with a 4-mm punch was the only way to establish the correct diagnosis. The defect from the biopsy was closed with 5-0 nylon sutures to minimize scarring.

The pathological findings included interface dermatitis, apoptotic keratinocytes, and a brisk periadnexal lymphocytic infiltrate, which—given the morphological and historical context—were entirely consistent with discoid lupus erythematosus (DLE; otherwise known as subacute cutaneous lupus erythematosus). Subsequent bloodwork failed to show any connection with systemic lupus erythematosus (SLE), which is not surprising because only about 18% of DLE cases evolve into SLE.

DLE is more common in women, especially in those with skin of color. The associated lesions are seldom as impressive as this patient’s, manifesting as papulosquamous patches typically found on the ears, neck, face, arms, and other sun-exposed areas. Indeed, it appears that sun exposure is a major trigger for the disease—a clue that can assist with the diagnosis.

TREATMENT

In addition to proscribing excessive sun exposure, providers should encourage the use of sunscreen. DLE is often treated with topical steroids. More advanced cases, such as this patient’s, may require oral hydroxychloroquine (200 mg bid). Though these treatments are effective in most cases, DLE can leave serious scarring and/or discoloration, especially in those with darker skin.

New data will add fuel to the ongoing debate over the age at which mammography screening for breast cancer should begin. Many guidelines recommend starting at age 50.

But yearly mammography between the ages of 40 and 49 years was associated with a “substantial and significant” 25% reduction in breast cancer mortality during the first 10 years of follow-up, according to new data from the UK Age Trial.

The researchers calculated that 1,150 women needed to undergo screening in the age group of 40-49 years to prevent 1 breast cancer death, or about 1 breast cancer death prevented per 1,000 screened.

However, they also noted that, in the years since the trial first began, there have been improvements in the treatment of breast cancer, so “there might be less scope for screening to reduce mortality in our current era.”

The study was published online August 12 in Lancet Oncology.

“Our results do indicate that screening before age 50 does indeed prevent deaths from breast cancer, with a minimal additional burden of overdiagnosis,” said lead author Stephen W. Duffy, MSc, director of the policy research unit in cancer awareness, screening and early diagnosis, at Queen Mary University, London.

That said, Dr. Duffy explained they do not expect policy makers to extend the age range on the basis of these results alone. “For one thing, they will want to consider costs, both human and financial.” “For another, at this time, the services are concentrating on recovering from the hiatus caused by the COVID-19 crisis, and, at this time, it would be impractical to try to expand the eligibility for screening.”

“I would say our results indicate that lowering the age range, although not necessarily to 40 but to some age below 50, will be at least worth considering when the current crisis is over,” he added.
 

Guideline recommendations differ

Breast cancer screening guidelines have generated debate, much of which has focused on the age at which to begin screening.

The U.S. Preventive Services Task Force and American College of Physicians recommend screening every other year, on average, for women between the ages of 50 and 74 years.

However, other organizations disagree. The American College of Radiology and Society of Breast Imaging both recommend annual mammograms starting at age 40, and continuing “as long as they are in good health.”

In the UK, where the study was conducted, a national breast cancer screening program offers mammography to women aged 50-70 years every 3 years.

Given the uncertainty that continues to exist over the optimal age for average-risk women to begin screening, the UK Age Trial set out to assess if screening should begin at a younger age and if that might lead to overdiagnosis of breast cancer.

Results from the study’s 17-year follow-up, published in 2015, showed a reduction in breast cancer mortality with annual screening, beginning at age 40 years, which was significant in the first 10 years after participants were randomized (Lancet Oncol. 2015;16:1123-32).

In the current study, Dr. Duffy and colleagues report on breast cancer incidence and mortality results in the UK Age trial after 23 years of follow-up.

The cohort included 160,921 women enrolled between Oct. 14, 1990, and Sept. 24, 1997, who were randomized to screening (n = 53,883) or the control group (n = 106,953).

Of those screened during the study period, 7,893 (18.1%) had at least one false-positive result. There were 10,439 deaths, of which 683 (7%) were attributed to breast cancer diagnosed during the study period.

At 10 years of follow-up, death from breast cancer was significantly lower among women in the screening versus control group (83 vs 219 deaths; relative risk, 0.75; P = .029).

However, no significant reduction was observed thereafter, with 126 versus 255 deaths occurring after more than 10 years of follow-up (RR, 0.98; 95% confidence interval, 0.79-1.22; P = .86), the authors note.

“This follow-up indicates that the gain in survival was concentrated in the first 10 years after the women began to be screened,” commented Kevin McConway, PhD, emeritus professor of applied statistics at the Open University, Milton Keynes, England.

“In those first 10 years, out of every 10,000 women invited for screening, on average, about 16 died of breast cancer, while in every 10,000 women in the control group who did not get the screening, on average, 21 died. These numbers indicate that lives were saved,” he said.

“But they also indicate that death from breast cancer was pretty rare in women of that age,” he pointed out.

“Because breast cancer deaths in younger women are not common, the estimates of breast cancer death rates are not very precise, despite the fact that the trial involved 160,000 women,” he said.

“Over the whole follow-up period so far, the difference in numbers of deaths between those who were screened in their 40s and those who were not is 6 deaths for every 10,000 women, but because of the statistical uncertainty, this figure could plausibly be larger, at 13 per 10,000. Or, in fact, the data are also consistent with a very slightly higher death rate [1 death per 10,000 women] in those who had the screening,” Dr. McConway explained.

“But none of those numbers is very large, out of 10,000 women. Allowing for the fact that not every woman invited for screening will actually attend the screening, the researchers estimate that 1,150 women would have to be screened in their 40s to prevent one breast cancer death,” he noted.
 

U.S. experts support starting screening at 40

“The American Society of Breast Surgeons has continued to recommend screening women at the age of 40,” said Stephanie Bernik, MD, FACS, chief of breast surgery, Mount Sinai West, and associate professor of surgery at the Icahn School of Medicine at Mount Sinai, New York. “There is no question that screening earlier saves more lives, and this study adds to the body of evidence already available.”

She pointed out that the argument against early screening was that there were many false positives, which, in turn, increased cost and anxiety. “Because women in their 40s are in the prime of their lives, often with young children, it seems as though screening would be paramount. Furthermore, it is well known that the sooner you find a cancer, the better, as the treatment needed to cure the cancer is less toxic and less dramatic.”

Catherine Tuite, MD, section chief, breast radiology, Fox Chase Cancer Center, Philadelphia, echoed a similar viewpoint. “There is no real debate on this issue. The USPSTF recommends beginning screening mammography at age 50, and it is no secret that this is a recommendation based on cost, not on saving women’s lives.”

She emphasized that these recommendations were made without the input of expert physicians. “The data, reaffirmed by this publication, have always been clear that the most years of life saved from deaths due to breast cancer are achieved in women who begin screening mammography at age 40. We know that one-sixth of all breast cancers are diagnosed before age 50, and many of these cancers are the most aggressive types of breast cancer.

“The guidelines from every organization representing health care professionals who actually diagnose and care for women with breast cancer recommend that all women of average risk begin annual screening mammography at age 40 and continue as long as the woman is in good health, with life expectancy of 10 years,” she continued.

As for screening intervals, annual mammogram is also recommended for all age groups in the United States. At her institutions, she explained that they are currently enrolling women into the TMIST screening mammogram trial, which is, among other endpoints, evaluating a biannual screening interval for postmenopausal women of lower than average risk, but again, outside of a trial setting, yearly screening for all women is recommended.

Dr. Duffy commented that, in the United Kingdom, the current screening protocol for mammograms is every 3 years, which he said “works well in women over the age of 50 years.” But for younger women, more frequent screening would be need – in this study, screening was done annually.

“The results not only from our study but from others around the world suggest that this [3-year screening interval] would not be very effective in women under 50, due partly to the denser breast tissue of younger women and partly to the faster progression on average of cancers diagnosed in younger women,” he said. “Some counties in Sweden, for example, offer screening to women under 50 at 18-month intervals, which seems more realistic.”

The study was funded by the Health Technology Assessment program of the National Institute for Health Research. Dr. Duffy reported also receiving grants from the NIHR outside this trial. Dr. Bernik, Dr. Tuite, and Dr. Hodgson reported no relevant financial relationships.

Of those screened during the study period, 7,893 (18.1%) had at least one false-positive result. There were 10,439 deaths, of which 683 (7%) were attributed to breast cancer diagnosed during the study period.

At 10 years of follow-up, death from breast cancer was significantly lower among women in the screening versus control group (83 vs 219 deaths; relative risk, 0.75; P = .029).

However, no significant reduction was observed thereafter, with 126 versus 255 deaths occurring after more than 10 years of follow-up (RR, 0.98; 95% confidence interval, 0.79-1.22; P = .86), the authors note.

“This follow-up indicates that the gain in survival was concentrated in the first 10 years after the women began to be screened,” commented Kevin McConway, PhD, emeritus professor of applied statistics at the Open University, Milton Keynes, England.

“In those first 10 years, out of every 10,000 women invited for screening, on average, about 16 died of breast cancer, while in every 10,000 women in the control group who did not get the screening, on average, 21 died. These numbers indicate that lives were saved,” he said.

“But they also indicate that death from breast cancer was pretty rare in women of that age,” he pointed out.

“Because breast cancer deaths in younger women are not common, the estimates of breast cancer death rates are not very precise, despite the fact that the trial involved 160,000 women,” he said.

“Over the whole follow-up period so far, the difference in numbers of deaths between those who were screened in their 40s and those who were not is 6 deaths for every 10,000 women, but because of the statistical uncertainty, this figure could plausibly be larger, at 13 per 10,000. Or, in fact, the data are also consistent with a very slightly higher death rate [1 death per 10,000 women] in those who had the screening,” Dr. McConway explained.

“But none of those numbers is very large, out of 10,000 women. Allowing for the fact that not every woman invited for screening will actually attend the screening, the researchers estimate that 1,150 women would have to be screened in their 40s to prevent one breast cancer death,” he noted.
 

U.S. experts support starting screening at 40

“The American Society of Breast Surgeons has continued to recommend screening women at the age of 40,” said Stephanie Bernik, MD, FACS, chief of breast surgery, Mount Sinai West, and associate professor of surgery at the Icahn School of Medicine at Mount Sinai, New York. “There is no question that screening earlier saves more lives, and this study adds to the body of evidence already available.”

She pointed out that the argument against early screening was that there were many false positives, which, in turn, increased cost and anxiety. “Because women in their 40s are in the prime of their lives, often with young children, it seems as though screening would be paramount. Furthermore, it is well known that the sooner you find a cancer, the better, as the treatment needed to cure the cancer is less toxic and less dramatic.”

Catherine Tuite, MD, section chief, breast radiology, Fox Chase Cancer Center, Philadelphia, echoed a similar viewpoint. “There is no real debate on this issue. The USPSTF recommends beginning screening mammography at age 50, and it is no secret that this is a recommendation based on cost, not on saving women’s lives.”

She emphasized that these recommendations were made without the input of expert physicians. “The data, reaffirmed by this publication, have always been clear that the most years of life saved from deaths due to breast cancer are achieved in women who begin screening mammography at age 40. We know that one-sixth of all breast cancers are diagnosed before age 50, and many of these cancers are the most aggressive types of breast cancer.

“The guidelines from every organization representing health care professionals who actually diagnose and care for women with breast cancer recommend that all women of average risk begin annual screening mammography at age 40 and continue as long as the woman is in good health, with life expectancy of 10 years,” she continued.

As for screening intervals, annual mammogram is also recommended for all age groups in the United States. At her institutions, she explained that they are currently enrolling women into the TMIST screening mammogram trial, which is, among other endpoints, evaluating a biannual screening interval for postmenopausal women of lower than average risk, but again, outside of a trial setting, yearly screening for all women is recommended.

Dr. Duffy commented that, in the United Kingdom, the current screening protocol for mammograms is every 3 years, which he said “works well in women over the age of 50 years.” But for younger women, more frequent screening would be need – in this study, screening was done annually.

“The results not only from our study but from others around the world suggest that this [3-year screening interval] would not be very effective in women under 50, due partly to the denser breast tissue of younger women and partly to the faster progression on average of cancers diagnosed in younger women,” he said. “Some counties in Sweden, for example, offer screening to women under 50 at 18-month intervals, which seems more realistic.”

The study was funded by the Health Technology Assessment program of the National Institute for Health Research. Dr. Duffy reported also receiving grants from the NIHR outside this trial. Dr. Bernik, Dr. Tuite, and Dr. Hodgson reported no relevant financial relationships.

As most of you know, Medicare publishes its proposed rule, which determines the physician fee schedule, around July 1 each year, accepts comments for 60 days, and then publishes a final rule on or around Nov. 1, which becomes final on Jan. 1 of the following year. The proposed rule is watched closely and has great impact, because not only are Medicare fees based on the rule, but most private insurances are based on Medicare.

This year’s proposed rule, announced in early August, is extraordinary by any past standard. It can be found here.

It cuts the conversion factor (which is what the work, practice expense, and malpractice values are multiplied by to get a payment) by 10.6%, from $36.09 to $32.26. This is necessary to maintain “budget neutrality” since there is a fixed pool of money, and payments for cognitive services are increasing. The overall effect on dermatology is a 2% cut, which is mild, compared with other specialties, such as nurse anesthetists and radiologists, both with an 11% decrease; chiropractors, with a 10% decrease; and interventional radiology, pathology, physical and occupational therapy, and cardiac surgery, all with a 9% decrease. General surgery will see a 7% decrease. Those with major increases are endocrinology, with a 17% increase; rheumatology, with a 16% increase; and hematology/oncology, with a 14% increase.

The overall push by CMS (and the relative value update committee) is to improve the pay for cognitive services, that is evaluation and management (E/M) services. Since dermatology also provides such services, the effect of the proposed rule will vary dramatically depending on your case mix. I must also point out that, since existing overhead is relatively fixed, say at 50%, a 10% decrease in revenue may translate into a 20% loss in physician income.


 

The good

Simplified coding and billing requirements for E/M visits will go into effect Jan. 1, 2021. For dermatology, any visit where a decision to do a minor procedure or prescribe a medication takes place will become a level 4 visit. Most of the useless documentation requirements and need to examine multiple organ systems will be eliminated. The most common E/M code currently used by dermatologists is a level 3, and this will on average move up to a level 4. Thus, general dermatology will benefit from the new rule. For example, if a dermatologist sees a patient and does a tangential biopsy of the skin, the payment will be $214.52, compared with $178.65 in 2020.

The bad

As mentioned above, the impact will vary by case mix. Those doing a lot of surgery will see a much larger cut. Mohs surgeons, for example will see about a 6.5% decrease.¹

Aggravating the cuts to surgery is the fact that, while CMS has bolstered the pay for E/M stand-alone codes, they did not increase the reimbursement level of the built-in follow-up visits inside the 10- and 90-day global periods.

The ugly

Procedure codes with a lot of practice expense built into them, such as Mohs and reconstruction, are not hit as hard by the conversion factor cut because the practice expense is generally spared. There is much less practice expense in a pathology code so dermatopathology faces the most severe cuts. Pathology and other specialties that do not generally bill office/outpatient E/M codes are estimated to see the greatest decrease in payment in 2021.

Code 88305, the most common dermatopathology code, will decrease overall from $71.46 to $66.78 (–6.5%). Digging a little deeper, we find that the technical charge (the payment to process and make the slide) actually increases from $32.12 to $32.26, but the professional component (the interpretation of the slide and report generation) decreases from $39.34 to $34.52 (–12.3%).

I must also point out that this proposed rule allows for nurse practitioners (NPs), clinical nurse specialists (CNSs), physician assistants (PAs), and certified nurse-midwives (CNMs) to supervise the performance of diagnostic tests in addition to physicians. I wonder if we will see an increase in billing of dermatopathology by the untrained.

Adding more confusion – and an additional hit to hospital-based practices – is the federal appeals court decision affirming the ability of the Centers for Medicare & Medicaid Services to mandate site-neutral payments for E/M codes. This means that hospital-affiliated practices, which used to enjoy payment of up to 114% more than offices, will be paid the same as offices. This will save CMS $300 million, but these savings will not be flowing back into the physician fee schedule.

Fixing this will require congressional action since CMS is bound by law to maintain budget neutrality. The specialty societies saw this coming and have already been lobbying furiously to waive budget neutrality requirements, especially in this time of a pandemic that has had an adverse impact on physicians. This is noted in detail on the AADA website, accessible to AAD members.

Since this will take a legislative fix, you should contact your congressional representative or senator and ask them to enact legislation to waive Medicare’s budget neutrality requirements to apply the increased E/M adjustment to all 10- and 90-day global code values. You might also inquire where the $300 million saved by site neutral payment reform will go, and suggest applying it towards restoring the conversion factor to a more normal number.

The Diagnosis: Erythropoietic Protoporphyria 

Erythropoietic protoporphyria (EPP) is an autosomal-recessive photodermatosis that results from loss of activity of ferrochelatase, the last enzyme in the heme biosynthetic pathway.¹ Erythropoietic protoporphyria normally involves sun-exposed areas of the body. Skin that is exposed to sunlight develops intense burning and stinging pain followed by erythema, edema, crusting, and petechiae that develops into waxy scarring over time. In contrast to other porphyrias, blistering generally is not seen.² Accurate diagnosis often can be delayed by a decade or more following symptom onset due to the prominence of subjective pain as the presenting sign.  

The histologic appearance of EPP differs depending on the chronicity of lesions. Biopsies of acute lesions show vacuolization of epidermal cells with intercellular edema, vacuolization and cytolysis of endothelial cells in superficial blood vessels, and focal red blood cell extravasation.^3,4 A largely neutrophilic inflammatory infiltrate can be present.⁵ Hyaline cuffing develops over time in and around vessels in the papillary and superficial reticular dermis with notable sparing of adnexal structures. The perivascular deposits are strongly periodic acid-Schiff (PAS) positive and diastase resistant (Figure 1). Direct immunofluorescence shows mainly IgG and some IgM, fibrinogen, and C3 outlining characteristic donut-shaped blood vessels in the papillary dermis.⁶ The prominent thickness of the perivascular hyaline material depositions and the absence of subepidermal blistering can help differentiate EPP from porphyria cutanea tarda (PCT) and pseudoporphyria.^6,7 When the deposition is extensive and involves the surrounding dermis, EPP can mimic colloid milium. Additional histologic differential diagnoses of EPP include other dermal depositional diseases such as lipoid proteinosis and amyloidosis.  

Lipoid proteinosis is an autosomal-recessive multisystem genodermatosis caused by mutations in extracellular matrix gene 1, ECM1. The first clinical sign can be a hoarse cry in infancy due to infiltration of vocal cords.³ Development of papulonodular lesions along the eyelids can result in a string-of-beads appearance called moniliform blepharosis, which is pathognomonic for lipoid proteinosis.⁶ With chronicity, the involved skin can become yellow, waxy, and thickened, particularly in the flexures or areas of trauma. Histologically, the dermis in lipoid proteinosis becomes diffusely thickened due to deposition of PAS-positive eosinophilic hyaline material that stains weakly with Congo red and thioflavin T.⁶ Early lesions demonstrate pale pink, hyalinelike thickening of the papillary dermal capillaries. Chronic lesions reveal an acanthotic epidermis, occasional papillomatosis with overlying hyperkeratosis, and a thickened dermis where diffuse thick bundles of pink hyaline deposits are oriented perpendicularly to the dermoepidermal junction.^1,6 Lipoid proteinosis can be differentiated from EPP by the involvement of adnexal structures such as hair follicles, sebaceous glands, and arrector pili muscles (Figure 2), as opposed to EPP where adnexal structures are spared.¹ Additionally, depositions in lipoid proteinosis are centered around both superficial and deep vessels with an onion skin-like pattern, while EPP involves mainly superficial vessels with more mild and focal hyalinization.

Juvenile colloid milium (JCM) is a rare condition that presents before puberty with discrete, yellow-brown, translucent papules predominantly located on the cheeks and nose and around the mouth. A gelatinous material can be expressed after puncturing a lesion.⁶ Gingival deposits and ligneous conjunctivitis also can be present. On histopathology, JCM shows degeneration of epidermal keratinocytes that form colloid bodies within the superficial dermis following apoptosis.⁶ Hematoxylin and eosin staining shows amorphous, fissured, pale pink deposits completely filling and expanding the superficial to mid dermis with clefting and no inflammation (Figure 3). Spindle-shaped fibroblasts may be seen within the lines of colloid fissuring and dispersed throughout the deposits.¹ Histologically, JCM can be differentiated from EPP because deposits in EPP are distributed around and within superficial blood vessel walls, causing prominent vascular thickening not seen in JCM.⁶ The adult variant of colloid milium also can be distinguished from EPP by the presence of solar elastosis, which is absent in EPP due to a history of sun avoidance.^3,7  

Lichen amyloidosis presents with highly pruritic, red-brown, hyperkeratotic papules that commonly are found on the anterior lower legs and extensor forearms.¹ The calves, ankles, dorsal aspects of the feet, thighs, and trunk also may be affected. Excoriations, lichenification, and nodular prurigo-like lesions due to chronic scratching can be present.⁶ Lichen amyloidosis is characterized by large, pink, amorphous deposits in the papillary dermis with epidermal acanthosis, hypergranulosis, and hyperkeratosis (Figure 4).⁶ Perivascular deposits are not a feature of primary cutaneous localized amyloid lesions.⁶ The diagnosis can be confirmed with Congo red staining under polarized light, which classically demonstrates apple green birefringence.¹ For cases of amyloid that are not detected by Congo red or are not clear-cut, direct immunofluorescence and immunohistochemistry can be used as adjuncts for diagnosis. Amyloid deposits fluoresce positively for immunoglobulins or complements, particularly IgM and C3,⁸ and immunohistochemistry confirms the presence of keratin epitopes in deposits.⁹  

Porphyria cutanea tarda can appear histologically similar to EPP. Caterpillar bodies, or linearly arranged eosinophilic PAS-positive globules in the epidermis overlying subepidermal bullae, are a diagnostic histopathologic finding in both PCT and EPP but are seen in less than half of both cases.^7,10 Compared to EPP, the perivascular deposits in PCT typically are less pronounced and limited to the vessel wall with smaller hyaline cuffs (Figure 5).⁷ Additionally, solar elastosis can be seen in PCT lesions but not in EPP, as patients with PCT tend to be older and have increased cumulative sun damage.

Excoriations, lichenification, and nodular prurigo-like lesions due to chronic scratching can be present.⁶ Lichen amyloidosis is characterized by large, pink, amorphous deposits in the papillary dermis with epidermal acanthosis, hypergranulosis, and hyperkeratosis (Figure 4).⁶ Perivascular deposits are not a feature of primary cutaneous localized amyloid lesions.⁶ The diagnosis can be confirmed with Congo red staining under polarized light, which classically demonstrates apple green birefringence.¹ For cases of amyloid that are not detected by Congo red or are not clear-cut, direct immunofluorescence and immunohistochemistry can be used as adjuncts for diagnosis. Amyloid deposits fluoresce positively for immunoglobulins or complements, particularly IgM and C3,⁸ and immunohistochemistry confirms the presence of keratin epitopes in deposits.⁹  

Porphyria cutanea tarda can appear histologically similar to EPP. Caterpillar bodies, or linearly arranged eosinophilic PAS-positive globules in the epidermis overlying subepidermal bullae, are a diagnostic histopathologic finding in both PCT and EPP but are seen in less than half of both cases.^7,10 Compared to EPP, the perivascular deposits in PCT typically are less pronounced and limited to the vessel wall with smaller hyaline cuffs (Figure 5).⁷ Additionally, solar elastosis can be seen in PCT lesions but not in EPP, as patients with PCT tend to be older and have increased cumulative sun damage.  

The Diagnosis: Erythropoietic Protoporphyria 

Erythropoietic protoporphyria (EPP) is an autosomal-recessive photodermatosis that results from loss of activity of ferrochelatase, the last enzyme in the heme biosynthetic pathway.¹ Erythropoietic protoporphyria normally involves sun-exposed areas of the body. Skin that is exposed to sunlight develops intense burning and stinging pain followed by erythema, edema, crusting, and petechiae that develops into waxy scarring over time. In contrast to other porphyrias, blistering generally is not seen.² Accurate diagnosis often can be delayed by a decade or more following symptom onset due to the prominence of subjective pain as the presenting sign.  

The histologic appearance of EPP differs depending on the chronicity of lesions. Biopsies of acute lesions show vacuolization of epidermal cells with intercellular edema, vacuolization and cytolysis of endothelial cells in superficial blood vessels, and focal red blood cell extravasation.^3,4 A largely neutrophilic inflammatory infiltrate can be present.⁵ Hyaline cuffing develops over time in and around vessels in the papillary and superficial reticular dermis with notable sparing of adnexal structures. The perivascular deposits are strongly periodic acid-Schiff (PAS) positive and diastase resistant (Figure 1). Direct immunofluorescence shows mainly IgG and some IgM, fibrinogen, and C3 outlining characteristic donut-shaped blood vessels in the papillary dermis.⁶ The prominent thickness of the perivascular hyaline material depositions and the absence of subepidermal blistering can help differentiate EPP from porphyria cutanea tarda (PCT) and pseudoporphyria.^6,7 When the deposition is extensive and involves the surrounding dermis, EPP can mimic colloid milium. Additional histologic differential diagnoses of EPP include other dermal depositional diseases such as lipoid proteinosis and amyloidosis.  

Lipoid proteinosis is an autosomal-recessive multisystem genodermatosis caused by mutations in extracellular matrix gene 1, ECM1. The first clinical sign can be a hoarse cry in infancy due to infiltration of vocal cords.³ Development of papulonodular lesions along the eyelids can result in a string-of-beads appearance called moniliform blepharosis, which is pathognomonic for lipoid proteinosis.⁶ With chronicity, the involved skin can become yellow, waxy, and thickened, particularly in the flexures or areas of trauma. Histologically, the dermis in lipoid proteinosis becomes diffusely thickened due to deposition of PAS-positive eosinophilic hyaline material that stains weakly with Congo red and thioflavin T.⁶ Early lesions demonstrate pale pink, hyalinelike thickening of the papillary dermal capillaries. Chronic lesions reveal an acanthotic epidermis, occasional papillomatosis with overlying hyperkeratosis, and a thickened dermis where diffuse thick bundles of pink hyaline deposits are oriented perpendicularly to the dermoepidermal junction.^1,6 Lipoid proteinosis can be differentiated from EPP by the involvement of adnexal structures such as hair follicles, sebaceous glands, and arrector pili muscles (Figure 2), as opposed to EPP where adnexal structures are spared.¹ Additionally, depositions in lipoid proteinosis are centered around both superficial and deep vessels with an onion skin-like pattern, while EPP involves mainly superficial vessels with more mild and focal hyalinization.

Juvenile colloid milium (JCM) is a rare condition that presents before puberty with discrete, yellow-brown, translucent papules predominantly located on the cheeks and nose and around the mouth. A gelatinous material can be expressed after puncturing a lesion.⁶ Gingival deposits and ligneous conjunctivitis also can be present. On histopathology, JCM shows degeneration of epidermal keratinocytes that form colloid bodies within the superficial dermis following apoptosis.⁶ Hematoxylin and eosin staining shows amorphous, fissured, pale pink deposits completely filling and expanding the superficial to mid dermis with clefting and no inflammation (Figure 3). Spindle-shaped fibroblasts may be seen within the lines of colloid fissuring and dispersed throughout the deposits.¹ Histologically, JCM can be differentiated from EPP because deposits in EPP are distributed around and within superficial blood vessel walls, causing prominent vascular thickening not seen in JCM.⁶ The adult variant of colloid milium also can be distinguished from EPP by the presence of solar elastosis, which is absent in EPP due to a history of sun avoidance.^3,7
