We are in the middle of a measles epidemic, there’s no denying it. Measles was declared eliminated in 2000, but reported cases in the United States have been on the rise, and are now at the highest number since 2014. Five months into 2019, there have been 839 reported cases as of May 13). Measles outbreaks (defined by the Centers for Disease Control and Prevention as three or more cases) have been reported in California, Georgia, Maryland, Michigan, New Jersey, New York, and Pennsylvania. When vaccination rates fall, it is easy for measles to spread. The virus is highly contagious in nonimmune people, because of its airborne spread and its persistence in the environment for hours.
 

First – is it really measles?

When there is a measles outbreak, there is a heightened concern to “rule out” measles in any febrile child with a rash. It can be difficult to distinguish the maculopapular rash of measles from similar rashes that occur with more benign viral illnesses. Adding to the challenge, the last major measles outbreak in the United States was over 2 decades ago, and many practicing pediatricians have never seen a single case. So, what clinical features can help distinguish measles from other febrile illnesses?

The prodromal phase of measles lasts approximately 2-4 days and children have high fevers (103°-105° F), anorexia, and malaise. Conjunctivitis, coryza, and cough develop during this phase, and precede any rash. Koplik spots appear during the prodromal phase, but are not seen in all cases. These spots are 1- to 3-mm blue-white lesions on an erythematous base on the buccal mucosa, classically opposite the first molar. The spots often slough once the rash appears. The rash appears 2-4 days after the onset of fever, and is initially maculopapular and blanching. The first lesions appear on the face and neck, and the rash spreads cranial to caudal, typically sparing palms and soles. After days 3-4, the rash will no longer blanch. High fevers persist for 2-4 more days with rash, ongoing respiratory symptoms, conjunctivitis, and pharyngitis. Note that the fever will persist even with development of the rash, unlike in roseola.

It is not only important to diagnosis measles from a public health standpoint, but also because measles can have severe complications, especially in infants and children under 5 years. During the 1989-1991 outbreak, the mortality rate was 2.2 deaths per 1,000 cases (J Infect Dis. 2004 May 1. doi: 10.1086/377694).

Six percent of patients develop pneumonia, which in infants and toddlers can lead to respiratory distress or failure requiring hospitalization. Pneumonia is responsible for 60% of measles deaths, according to the CDC “Pink Book,” Epidemiology and Prevention of Vaccine-Preventable Diseases, chapter 13 on measles, 13th Ed., 2015. Ocular complications include keratitis and corneal ulceration. Measles also can cause serious neurologic complications. Encephalitis, seen in 1 per 1,000 cases, usually arises several days after the rash and may present with seizure or encephalopathy. Acute disseminated encephalomyelitis (ADEM), an inflammatory demyelinating disease of the central nervous system, occurs in approximately 1 per 1,000 cases, typically presents during the recovery phase (1-2 weeks after rash), and can have long-term sequelae. Subacute sclerosing panencephalitis (SSPE) is a progressive and fatal neurodegenerative disorder, and presents 7-10 years after measles infection.
 

Should you transfer the patient to a hospital?

Unless there is a medical need for the child to be admitted, sending a patient with potential measles to the hospital is not necessary, and can cause exposure to a large group of medical personnel, and patients who cannot be vaccinated (such as infants, immunocompromised patients, and pregnant women). However, if there is concern for complications such as seizures, encephalitis, or pneumonia, then transfer is indicated. Call the accepting hospital in advance so the staff can prepare for the patient. During transfer, place a standard face mask on the patient and instruct the patient not to remove it.

For hospitals accepting a suspected measles case, meet the patient outside of the facility and ensure that the patient is wearing a standard face mask. All staff interacting with the patient should practice contact and airborne precautions (N95 respirator mask). Take the patient directly to an isolation room with negative airflow. Caution pregnant staff that they should not have contact with the patient.
 

Which diagnostic tests should you use?

Diagnosis can be made based on serum antibody tests (measles IgM and IgG), throat or urine viral cultures, and nasopharyngeal and throat specimen polymerase chain reaction (PCR) testing. The CDC recommends obtaining a serum sample for measles IgM testing and a throat swab for PCR in all suspected cases, but local health departments vary in their specific testing recommendations. Familiarize yourself with the tests recommended by your local department of health, and where they prefer testing on outpatients to be done. Confirmed measles should be reported to your department of health.

What are considerations for community pediatric offices?

Update families in emails to call ahead if they suspect measles. This way the office can prepare a room for the family, and have the family immediately brought back without exposing staff and other families in the waiting area. It may be more prudent to examine these children at the end of the clinic day as the virus can persist for up to 2 hours on fomites and in the air. Therefore, all waiting areas and shared air spaces (including those with shared air ducts) should be cleared for 2 hours after the patient leaves.

When should you provide prophylaxis after exposure?

A patient with suspected measles does not require immediate vaccination. If it is measles, it is already too late to vaccinate. If measles is ruled out, the child should follow the standard measles vaccination guidelines.

Individuals are contagious from 4 days before to 4 days after the rash appears.

If measles is confirmed, all people who are unvaccinated or undervaccinated and were exposed to the confirmed case during the contagious period should be vaccinated within 72 hours of exposure. Infants 6 months or older may safely receive the MMR vaccine. However, infants vaccinated with MMR before their first birthday must be vaccinated again at age 12-15 months (greater than 28 days after prior vaccine) and at 4-6 years. Immunoglobulin prophylaxis should be given intramuscularly in exposed infants ages birth to less than 6 months, and in those ages 6-12 months who present beyond the 72-hour window. Unvaccinated or undervaccinated, exposed individuals at high risk for complications from measles (immunocompromised, pregnant) also should receive immunoglobulin.
 

What should you tell traveling families?

Several countries have large, ongoing measles outbreaks, including Israel, Ukraine, and the Philippines. Before international travel, infants 6-11 months should receive one dose of MMR vaccine, and children 12 months and older need two doses separated by at least 28 days. For unvaccinated or undervaccinated children, consider advising families to hold off travel to high-risk countries, or understand the indications to vaccinate a child upon return.

CHICAGO – Topical gentamicin counters the nonsense mutations that inhibit production of laminin 332 in infants with Herlitz junctional epidermolysis bullosa (H-JEB) to allow lesion healing, according to results of a small clinical study presented at the annual meeting of the Society for Investigative Dermatology.

“All of the children treated so far have responded,” reported Andrew Kwong, who will soon graduate from the Keck School of Medicine at the University of Southern California, Los Angeles.

H-JEB is an inherited blistering skin disease associated with nonsense mutations in the LAMA3, LAMB3, or LAMC2 genes that result in impaired production of functional laminin 332, an essential protein for epidermal-dermal adherence. At this time there are no effective therapies, and the disease is fatal.

The small clinical study was initiated after in vitro studies demonstrated that gentamicin restored functional laminin 332 in cultured keratinocytes from infants with H-JEB. The dose-dependent effect was credited to the ability of gentamicin to induce readthrough of premature stop codons that block production of laminin 332.

Data were presented on the first three infants with H-JEB treated with oral gentamicin. In each child, lesions were treated with topical 0.5% gentamicin twice daily for two weeks. Biopsies were taken prior to the initiation of treatment and at one and three months after treatment. The primary outcome was change in laminin 332, but clinical improvement was also monitored.

Although none of the infants had measurable laminin 332 prior to treatment, all lesions treated with topical gentamicin developed localized laminin 332 at the dermal-epidermal junction of the skin, Mr. Kwong reported. This expression, which was about 40% to 60% of that seen in normal skin, still persisted when evaluated three months after treatment.

The expression was associated with resolution of existing lesions and a reduced risk of developing new lesions, according to Mr. Kwong. In lesions that went untreated, there was no change.

Other molecular changes in the skin, such as increased expression and polarization of beta-4 integrin, were consistent with the ability of gentamicin to address the underlying pathophysiology of H-JEB. There were no adverse events observed.

By restoring functional laminin 332 in the skin, topical gentamicin appears to address the underlying cause of the bullae associated with H-JEB, but Mr. Kwong said that the next step is to determine whether intravenous gentamicin can address the systemic effects. If so, this treatment has the potential to improve survival. He reported that an infant with H-JEB was recently started on intravenous treatment, and initial results were encouraging.

Asked whether he would recommend topical gentamicin on the basis of these findings, Mr. Kwong cautioned that the case series remains very small, but he noted that the uniformity of the positive response is encouraging. He expects that off-label use of this novel and low-cost approach might be warranted in a population that has very limited therapeutic options.

BIRMINGHAM, ENGLAND – Intradermal delivery of a tumor necrosis factor inhibitor (TNFi) could offer patients with discoid lupus erythematosus (DLE) a much-needed additional treatment option, according to results of a phase 2, “proof-of-concept” study.

Sara Freeman/MDedge News

Overall, 14 (56%) of the 25 patients in the study achieved a 20% or greater reduction in disease activity from baseline to week 12 via intradermal injection of etanercept (Enbrel), which was assessed via the modified limited Score of Activity and Damage in DLE (ML-SADDLE). About half (48%) and one-fifth (20%) also achieved greater reductions of 50% and 70%, respectively.

“Discoid lupus is a chronic form of cutaneous lupus. Usually it occurs in visible areas like the face and scalp, causing scarring, so it’s really disabling and affects patients’ quality of life,” observed the lead study investigator Md Yuzaiful Md Yusof, MBChB, PhD, NIHR Academic Clinical Lecturer at the University of Leeds, England.

“It’s also one of the most resistant manifestations of lupus,” he said during a poster presentation at the annual conference of the British Society for Rheumatology. “Usually, when people have discoid lupus, the dermatologist gives antimalarial treatment, but only 50% of people respond to these drugs. So, what happens to the rest of them?” Basically, it is trial and error, Dr. Md Yusof said; some patients may be given disease-modifying antirheumatic drugs and in some patients this may work well, but in others there may be toxicity that contraindicates treatment.

B-cell therapy with rituximab (Rituxan) has not been successful, he said. In a previous study of 35 patients with refractory discoid lupus, none of the patients responded to rituximab and half of them actually flared after taking the drug.

There is a pathologic case for using anti-TNF therapy in DLE, but the use of TNFis is not without concern. Such treatment can increase antinuclear antibody production and make lupus worse. “In order to overcome this, as the lesion is quite small, we don’t need to use a systemic approach,” Dr. Md Yusof explained in an interview. “If you give directly, it should just be confined to the lesion and not absorbed, that’s the whole idea of thinking outside the box.” He noted that if it worked, such treatment would be for inducing remission and not for maintenance.

The study, “Targeted therapy using intradermal injection of etanercept for remission induction in discoid lupus erythematosus” (TARGET-DLE) was designed to test the validity of using intradermal rather than subcutaneous TNFi therapy in patients with discoid lupus.

Dr. Md Yusof noted that only 25 patients needed to be recruited into the single-arm, prospective trial as a “Simon’s two-stage minimized design” was used (Control Clin Trials. 1989;10[1]:1-10). This involved treating the first few patients to see if a response occurred and if it did, carrying on with treating the others, but if no response occurred in at least two patients, the trial would stop completely.

Adult patients were eligible for inclusion if they had one or more active DLE lesions and had not responded to antimalarial treatment. Stable doses of DMARDs and up to 10 mg of oral prednisolone daily was permitted if already being taken prior to entering the study.

Etanercept was injected intradermally around the most symptomatic lesion once a week for up to 12 weeks. The dosage was determined based on the radius of the selected discoid lesion. Over an 18-month period, all 25 patients were recruited, including 18 women. The median age of patients was 47 years, and six had systemic lupus erythematosus. The median number of prior DMARDs was 5 but ranged from 1 to 16, indicating a very resistant patient population.

The primary endpoint was at least 6 of the 25 patients having at least a 20% reduction in ML-SADDLE at week 12; 14 (56%) patients achieved this.

“We didn’t use CLASI [Cutaneous Lupus Area and Severity Index Activity Score] because that only includes erythema and atrophy,” Dr. Md Yusof explained. “In discoid lupus, induration is quite important as well, so that’s why we used ML-SADDLE. We called it ‘modified limited’ because the original SADDLE score is based on the whole organ score, but we only calculated the one lesion that we wanted to treat.”

In addition to meeting the primary endpoint, several secondary endpoints were met, including significant improvements in scores on visual analog scales as determined by pre- and posttreatment scoring by physicians (53.1 mm vs. 23.2 mm; P less than .001) and patients (56.9 mm vs. 29.7 mm; P = .001). Mean Dermatology Life Quality Index (DLQI) score significantly improved between pre- and post treatment, as did blood perfusion under the skin based on laser Doppler imaging and infrared thermography. However, no difference was seen with optical coherence tomography.

“There were only four grade 3/4 toxicities, and importantly, none of the SLE patients got worse, and none with DLE only converted into SLE,” Dr. Md Yusof reported. Of the four grade 3/4 adverse events, two were chest infections, one was heart failure, and one was a worsening of chilblains.

“It was a full-powered phase 2 trial, and because it was positive, now we can go to phase 3 trial,” he added.

Before conducting a phase 3 trial, however, Dr. Md Yusof wants to refine how the TNFi is delivered. Perhaps an intradermal patch with microneedles could be used. This would be left on the skin for a short amount of time to allow drug delivery and then removed. It could help ensure that all patients comply with treatment and perhaps even self-administer, he noted.

“The median compliance rate was 80%, which is not too bad, but I think when we come to run a phase 3 trial, I’m looking to improve the drug delivery,” he said. Changing the delivery method will need to be validated before a phase 3 trial can be started.

The study was not commercially funded. Dr. Md Yusof had no disclosures. Pfizer provided the study drug free of charge.

BIRMINGHAM, ENGLAND – Intradermal delivery of a tumor necrosis factor inhibitor (TNFi) could offer patients with discoid lupus erythematosus (DLE) a much-needed additional treatment option, according to results of a phase 2, “proof-of-concept” study.

Overall, 14 (56%) of the 25 patients in the study achieved a 20% or greater reduction in disease activity from baseline to week 12 via intradermal injection of etanercept (Enbrel), which was assessed via the modified limited Score of Activity and Damage in DLE (ML-SADDLE). About half (48%) and one-fifth (20%) also achieved greater reductions of 50% and 70%, respectively.

“Discoid lupus is a chronic form of cutaneous lupus. Usually it occurs in visible areas like the face and scalp, causing scarring, so it’s really disabling and affects patients’ quality of life,” observed the lead study investigator Md Yuzaiful Md Yusof, MBChB, PhD, NIHR Academic Clinical Lecturer at the University of Leeds, England.

“It’s also one of the most resistant manifestations of lupus,” he said during a poster presentation at the annual conference of the British Society for Rheumatology. “Usually, when people have discoid lupus, the dermatologist gives antimalarial treatment, but only 50% of people respond to these drugs. So, what happens to the rest of them?” Basically, it is trial and error, Dr. Md Yusof said; some patients may be given disease-modifying antirheumatic drugs and in some patients this may work well, but in others there may be toxicity that contraindicates treatment.

B-cell therapy with rituximab (Rituxan) has not been successful, he said. In a previous study of 35 patients with refractory discoid lupus, none of the patients responded to rituximab and half of them actually flared after taking the drug.

A 60-year-old woman presents to dermatology with a longstanding complaint of a tender, irritated mass hanging from her lower abdomen. The patient says it started as a large fold in her lower abdomen but over the years has grown and become more pendulous. It is now large enough to interfere with normal activity, including walking.

Numerous providers, dermatologists included, have rendered diagnoses—most recently, hidradenitis suppurativa. The antibiotics prescribed for that diagnosis have not helped, however. Similarly, cultures performed on samples from draining sores on the mass’s posterior have failed to illuminate the situation, showing only mixed normal flora.

The patient’s primary care provider referred her to surgery for consideration of removal, or at least reduction, of the mass. The surgeon offered a presumptive diagnosis of elephantiasis nostras verrucosa of the pannus and agreed to perform the surgery. But the patient’s primary care provider requested a second opinion from dermatology.

EXAMINATION
The edematous, pendulous mass is the size of a soccer ball and hangs down from its abdominal base. When the patient stands, the mass stretches almost to the level of her knees. The anterior surface is edematous but otherwise normal in appearance. The intertriginous surfaces of the lesion look entirely different, with multiple small, draining puncta and a few open comedones.

The body of the mass is quite indurated but is neither hot nor tender. There are no comedones or cysts in other intertriginous locations, as might be seen in hidradenitis.

What’s the diagnosis?

DISCUSSION
This case involves a rare entity: vast lymphedema of the pannus leading to the formation of a pendulous mass so large that it filled the space between the patient’s legs, causing pain and discomfort. These findings are analogous to those seen in advanced venous insufficiency. Both manifestations share a name: elephantiasis nostras verrucosa. (Neither has anything to do with the more notorious cases of filarial elephantiasis seen in tropical locations.)

Elephantiasis nostras verrucosa of the lower extremities involves striking skin changes: edema, along with extreme thickening, papularity, and roughness of the skin. These typically manifest downward from just below the knee. The condition represents the effects of late-stage chronic venous insufficiency, often worsened by obesity and a sedentary lifestyle. Other causes of dependent lymphedema, such as congestive heart failure, can also contribute to the problem.

This same pathophysiologic process can affect other areas as well—including the pannus, as seen in this case. Since I had only ever encountered this problem in legs, I did a literature search. I found several references, all of which indicated that surgical removal (panniculectomy) was the best treatment. I could not find any information on the success rate of this surgery, but I did refer the patient back to the surgeon, who had made the correct diagnosis.

TAKE-HOME LEARNING POINTS

• Elephantiasis nostras verrucosa (ENV) is a consequence of uncontrolled venous insufficiency that commonly manifests on lower extremities.
• ENV is a distinctly rare (though not unknown) problem when areas other than legs are affected.
• This patient’s condition is, in my opinion, beyond the reach of medical treatment. But in milder cases, approaches such as weight loss and use of diuretics have been tried with mixed success.
• The best treatment appears to be surgical removal, which is not without potential complications: risk for infection, pain, prolonged recovery time, and wound dehiscence; these issues were discussed thoroughly with the case patient.

The differential diagnosis included psoriasis, drug eruption, and a cutaneous T-cell lymphoma.

A drug eruption could have been due to an over-the-counter medication or supplement, so the lack of improvement from stopping the antihypertensive medication did not rule out this diagnosis. Psoriasis does not always show erythema in persons of color, but these plaques were not typical of psoriasis. (There also were some flat patches that were even less typical of psoriasis.)

The FP performed a 4-mm punch biopsy on one of the hyperpigmented plaques on the abdomen. A 4-mm punch biopsy is generally an ideal method for determining the cause of an unknown skin rash, and it is usually better to choose a lesion on the upper body rather than below the waist if the rash is widespread. (See the Watch & Learn video on “Punch biopsy.”)

The FP also prescribed a 1-pound tub of 0.1% triamcinolone ointment for symptomatic relief as this could help any of the possible diagnoses being considered. The pathology report came back as mycosis fungoides, the most common type of cutaneous T-cell lymphoma.

The patient was sent to Hematology/Oncology for further evaluation and treatment. Mycosis fungoides can have both patches and plaques and frequently involves the trunk more than the extremities (which was the situation in this case). It is important to consider uncommon diagnoses like this in the differential when the initial diagnosis does not appear to be responding to treatment or there is something atypical about the presentation of an expected diagnosis.

A 25-year-old woman presented with an exceedingly tender right ear. She’d had the helix of her ear pierced 3 days prior to presentation and 2 days after that, the ear had become tender. The tenderness was progressively worsening and associated with throbbing pain. The patient, who’d had her ears pierced before, was otherwise in good health and denied fever, chills, or travel outside of the country. She had been going to the gym regularly and took frequent showers. Physical examination revealed an erythematous swollen ear that was tender to the touch (FIGURE). The entire auricle was swollen except for the earlobe. The patient also reported purulent material draining from the helical piercing site.

Diagnosis: Auricular perichondritis

Auricular perichondritis is an inflammation of the connective tissue surrounding the cartilage of the ear. Infectious and autoimmune factors may play a role. The underlying cartilage also may become involved. A useful clinical clue to the diagnosis of auricular perichondritis is sparing of the earlobe, which does not contain cartilage. Autoimmune causes typically have bilateral involvement. Infectious causes are usually associated with trauma and purulent drainage at the wound site. Ear piercings are an increasingly common cause, but perichondritis due to minor trauma, as a surgical complication, or in the absence of an obvious inciting trigger can occur. A careful history usually will reveal the cause.

In this case, the patient indicated that an open piercing gun at a shopping mall kiosk had been used to pierce her ear. Piercing with a sterile straight needle would have been preferable and less likely to be associated with secondary infection, as the shearing trauma to the perichondrium experienced with a piercing gun is thought to predispose to infection.¹ Exposure to fresh water from the shower could have been a source for Pseudomonas infection.¹

Differential: Pinpointing the diagnosis early is vital

A red and tender ear can raise a differential diagnosis that includes erysipelas, relapsing polychondritis, and auricular perichondritis. Erysipelas is a bacterial infection that spreads through the lymphatic system and is associated with intense and well-demarcated erythema. Erysipelas typically involves the face or lower legs. Infection after piercing or traumatic injury should raise suspicion of pseudomonal infection.^2-5 Untreated infection can spread quickly and lead to permanent ear deformity. Although the same pattern of inflammation can be seen in relapsing polychondritis, relapsing polychondritis typically involves both ears as well as the eyes and joints.

Prompt treatment is necessary to avoid cosmetic disfigurement

The timing of the reaction in our patient made infection obvious because Pseudomonas aeruginosa seems to have a particular affinity for damaged cartilage.²

Prompt treatment is necessary as infection can spread quickly and lead to cosmetic disfigurement.

Ciprofloxacin 500 mg twice daily is the treatment of choice. Although many skin infections can be empirically treated with oral cephalosporin, penicillin, or erythromycin, it is important to recognize that infected piercing sites and auricular perichondritis due to pseudomonal infection will not respond to these agents. That’s because these agents do not provide as good coverage for Pseudomonas as they do for Staphylococci or other bacteria more often associated with skin infection. Treatment with an agent such as amoxicillin and clavulanic acid or oral cephalexin can mean the loss of valuable time and subsequent cosmetic disfigurement.⁶

Continue to: When fluctuance is present...

When fluctuance is present, incision and drainage, or even debridement, may be necessary. When extensive infection leads to cartilage necrosis and liquefaction, treatment is difficult and may result in lasting disfigurement. Prompt empiric treatment currently is considered the best option.⁶

Our patient was prescribed a course of ciprofloxacin 500 mg every 12 hours for 10 days. She noted improvement within 2 days, and the infection resolved without complication.

THE CASE

A primiparous mother gave birth to a girl at 38 and 4/7 weeks via uncomplicated vaginal delivery. Prenatal labs were normal. Neonatal physical examination was normal and the child’s birth weight was in the 33rd percentile. APGAR scores were 8 and 9. The neonate was afebrile during hospitalization, with a heart rate of 120 to 150 beats/min and a respiratory rate of 30 to 48 breaths/min. Her preductal and postductal oxygen saturations were 100% and 98%, respectively. She was discharged on Day 2 of life, having lost only 3% of her birth weight.

The patient was seen in clinic on Day 6 of life for a well-child exam and was in the 17th percentile for weight. At another visit for a well-child exam on Day 14 of life, she had not fully regained her birth weight. At both visits, the mother reported no issues with breastfeeding and said she was supplementing with formula. The patient was seen again for follow-up on Days 16 and 21 of life and demonstrated no weight gain despite close follow-up with the Special Supplemental Nutrition Program for Women, Infants, and Children (WIC), which determined the newborn had some breastfeeding issues but seemed to be consuming adequate calories. However, WIC assessments revealed that during feeding, the child was expending too many calories and had nasal congestion. The patient was admitted to the hospital on Day 21 of life with a diagnosis of failure to thrive (FTT), at which point she was in the 12th percentile for weight.

THE DIAGNOSIS

Shortly after the infant was admitted, she showed signs of respiratory distress. On physical examination, the on-call resident noted intermittent retractions with inspiratory stridor, and the patient demonstrated intermittent severe oxygen desaturations into the 70s. She also was sucking her pacifier furiously, which appeared to provide some relief from the respiratory distress. The child’s parents noted that she had demonstrated intermittent periods of respiratory distress since shortly after birth that seemed to be increasing in frequency.

Upon careful examination, the on-call resident identified a cystic lesion at the base of the child’s tongue. The otolaryngologist on call was brought in for an urgent consultation but was unable to visualize the lesion on physical examination and did not recommend further intervention at that time. The patient continued to demonstrate respiratory distress with hypoxia and was transferred to the pediatric intensive care unit for close monitoring.

The next morning a second otolaryngology consultation was requested. A computed tomography scan of the neck demonstrated a 1.5-cm cystic-appearing mass at the base of the tongue that was obstructing the patient’s airway. Direct flexible bronchoscopy confirmed the radiographic findings. The patient underwent immediate surgical resection of the lesion using a laser. A clear and milky gray cystic fluid exuded from the cyst when the lesion was pierced. The otolaryngologist visualized a widely patent airway following excision of the lesion (FIGURE).

Pathology results revealed no evidence of malignancy. The final diagnosis was a simple base-of-tongue cyst.

DISCUSSION

Failure to thrive is common in neonates and occurs most often due to inadequate caloric intake; however, it also can be caused by systemic disease associated with inadequate gastrointestinal absorption or increased caloric expenditure, such as congenital heart disease, renal disease (eg, renal tubular acidosis), chronic pulmonary disease (eg, cystic fibrosis), laryngomalacia, malignancy, immunodeficiency, or thyroid disease.¹

Continue to: Respiratory distress

Respiratory distress in neonates also is common but tends to occur shortly after birth.² Conditions associated with respiratory distress in neonates include transient tachypnea of the newborn, respiratory distress syndrome, pneumothorax, persistent pulmonary hypertension of the newborn, pneumonia, and meconium aspiration syndrome.² Interestingly, there are additional reports in the literature of FTT and respiratory distress in neonates caused by obstructive pharyngeal lesions.^3-5

Mechanical obstruction should be considered in neonates with failure to thrive and respiratory distress.

Base-of-tongue cysts are rare in infants. Fewer than 50 cases were reported prior to 2011, with many being described as asymptomatic nonpainful lesions.⁶ Given the anatomic location of base-of-tongue cysts, the differential diagnosis should also include mucoceles, thyroglossal duct cysts, dermoid cysts, epidermoid cysts, vallecular cysts, hemangiomas, cystic hygromas, lymphangiomas, thyroid remnant cysts, teratomas, and hamartomas.^4,7,8 When tongue cysts are initially discovered, inspiratory stridor, FTT, swallowing deficits, oxygen desaturation, respiratory failure, and/or acute life-threatening events have been reported.^6,9,10

One important clinical observation made in our case was the use of an external apparatus to relieve the neonate’s respiratory distress. During physical examination, the on-call resident noted the patient was furiously sucking her pacifier, which seemed to reduce the respiratory difficulty and desaturations. It is known that non-nutritive sucking (NNS) can provide provisions for stress relief, improve oxygenation, and provide proprioceptive positioning of key anatomical structures within the oral cavity.¹¹ Without the use of an external apparatus like a pacifier during restful states, neonates may develop vacuum-glossoptosis syndrome, in which the dorsum of the tongue and the soft palate adhere to the posterior pharyngeal wall and obstruct the airway.¹² Our patient may have used the pacifier as an NNS task to move the tongue forward and break the glossoptosis-pharyngeal seal by sucking hard and fast during periods of respiratory distress, which reduced the potential for a vacuum-glossoptosis phenomenon that was likely created by the cyst during restful states.

Our patient was seen in clinic for follow-up after surgery on Day 35 of life. She was thriving and her weight was in the 24th percentile. She was seen again on Day 67 of life for a well-child exam and was in the 43rd percentile for weight.

THE TAKEAWAY

Non-nutritive sucking with a pacifier may relieve airway obstruction caused by base-of-tongue cysts.

There is a sizeable list of possible diagnoses to consider when a neonate presents with FTT and respiratory distress. It is important to consider mechanical obstruction as a possible diagnosis and one which, if identified early, may be lifesaving. Our case demonstrates a proposed mechanism by which a mechanical obstruction such as a base-of-tongue cyst can cause the vacuum-glossoptosis syndrome; it also highlights NNS as a potential means of overcoming this phenomenon.

Over the past year through early 2019, the US Preventive Services Task Force made 34 recommendations on 19 different topics. Twenty-six were reaffirmations of recommendations made in previous years (TABLE 1¹); the Task Force attempts to reassess topics every 7 years. Two new topics were addressed with 2 new recommendations, and 6 previous recommendations were revised or reversed (TABLE 2^2-9).

This Practice Alert discusses the new and the changed recommendations. (In 2018, the Practice Alert podcast series covered screening for ovarian cancer [April], prostate cancer [June], and cervical cancer [October], and EKG screening for cardiovascular disease [November].) All current Task Force recommendations are available on the USPSTF Web site.¹

New topics

Perinatal depression prevention

The Task Force recommends that clinicians counsel pregnant women and women in the first year postpartum who are at increased risk for perinatal depression, or refer for such services. The recommendation applies to those who are not diagnosed with depression but are at increased risk.

Perinatal depression can negatively affect both mother and child in several ways and occurs at a rate close to 9% during pregnancy and 37% during the first year postpartum.² The interventions studied by the Task Force included cognitive behavioral therapy and interpersonal therapy; most sessions were initiated in the second trimester of pregnancy and varied in number of sessions and intensity. The Task Force includes the following in the list of risks that should prompt a referral: a history of depression, current depressive symptoms that fall short of that needed for a depression diagnosis, low income, adolescent or single parenthood, recent intimate partner violence, elevated anxiety symptoms, physical or sexual abuse, or a history of significant negative life events. (See “Postpartum anxiety: More common than you think,” in the April issue.)

Atrial fibrillation

The Task Force found insufficient evidence to recommend for or against the use of electrocardiography (EKG) to screen for atrial fibrillation (AF).³ Atrial fibrillation is common, affecting 3% of men and 2% of women between the ages of 65 and 69 years, and it increases in prevalence with age.⁴ It is a major risk factor for stroke, although it is commonly first diagnosed after a stroke. Treatment with anticoagulant therapy reduces the incidence of stroke in patients with symptomatic AF, but this treatment is associated with the risk of major bleeding. The problem in screening for AF with EKG is that it is associated with misdiagnosis, over-treatment, and further testing. The Task Force could not find any direct evidence of the totality of benefits and harms of screening asymptomatic adults with EKG, and it raised the possibility that benefit with less harm might be achieved by screening with pulse palpation and heart auscultation, followed by EKG testing of those with an irregular pulse.

Revisions of previous recommendations

Cervical cancer screening

The Task Force continues to recommend screening for cervical cancer in women 21 to 65 years of age.⁵ The major change in the current recommendation is for women ages 30 to 65 years. For this group, the Task Force now recommends screening every 5 years with high-risk human papillomavirus (hrHPV) testing alone as a possible alternative to screening every 3 years with cytology alone. They also halfheartedly endorse co-testing as an option, even though it may result in more tests and procedures compared with either cytology or hrHPV testing alone, with equal effectiveness. For women ages 21 to 29 years, cervical cytology alone every 3 years is still the only recommended regimen.

Skin cancer prevention

The Task Force made 2 revisions to the 2012 recommendation on preventing skin cancer through behavioral counseling to avoid ultraviolet (UV) radiation.⁶ These recommendations continue to focus on those with fair skin. The first revision: The earliest age at which children (through their guardians) can benefit from counseling on UV avoidance has been lowered from age 10 years to 6 months. The second revision: Some adults older than age 24 can also benefit from such counseling if they have fair skin and other skin cancer risks such as using tanning beds, having a history of sunburns or previous skin cancer, having an increased number of nevi (moles) and atypical nevi, having human immunodeficiency virus (HIV) infection, having received an organ transplant, or having a family history of skin cancer.

Those at risk can reduce their chances of skin cancer by using broad-spectrum sunscreens and sun-protective clothing, and by avoiding sun exposure and indoor tanning beds.

Fall prevention

In a reversal of its 2012 recommendation, the Task Force now recommends against the use of vitamin D supplementation to prevent falls in community-dwelling adults 65 years or older.⁷ In a reanalysis of previous studies on this topic, along with new evidence, the Task Force concluded that vitamin D supplementation offers no benefit for preventing falls in adults who are not vitamin D deficient.

Screening for scoliosis in adolescents

In 2004 the USPSTF recommended against screening for idiopathic scoliosis in children and adolescents 10 to 18 years of age. In its most recent review, the Task Force continued to find no direct evidence of the benefit of screening and inadequate evidence on the long-term benefits of reduction in spinal curvature through exercise, surgery, and bracing. However, following a reanalysis of the potential harms of these treatments and the use of a new analytic framework, the Task Force concluded it is not possible at this time to assess the balance of benefits and harms of screening.⁸

Prostate cancer screening

In its most controversial action, the Task Force reversed its 2012 recommendation against routine prostate-specific antigen–based screening for prostate cancer in men ages 55 to 69 years and now lists this as a “C” recommendation.⁹ The potential benefits of screening include preventing 1.3 deaths from prostate cancer per 1000 men screened over 13 years and approximately 3 cases of metastatic prostate cancer. However, no trials have found a reduction in all-cause mortality from screening. Contrast that with the known harms of screening: 15% false positive results over 10 years; 1% hospitalization rate among those undergoing a prostate biopsy; over-diagnosis and resultant treatment of 20% to 50% of men diagnosed with prostate cancer through screening; and incontinence and erectile dysfunction in 20% and 67%, respectively, of men following prostatectomy.⁹

Evidence is insufficient to recommend for or against the use of electrocardiography in screening for atrial fibrillation.

Based on these outcomes, the Task Force “does not recommend screening for prostate cancer unless men express a preference for screening after being informed of and understanding the benefits and risks.”⁹ The Task Force continues to recommend against screening men ages 70 years and older.

Continue to: The change in this recommendation...

The change in this recommendation and its wording present dilemmas for family physicians: whether to discuss potential screening with all men ages 55 to 69; to selectively discuss it with those at high risk (principally African Americans and those with a strong family history of prostate cancer); or to address the issue only if a patient asks about it. In addition, if a man requests screening, how often should it be performed? Most clinical trials have found equal benefit from testing less frequently than every year, with fewer harms. The Task Force provided little or no guidance on these issues.

Final advice: D recommendations

The Task Force reaffirmed that 7 services have either no benefit or cause more harm than benefit (TABLE 1¹). Family physicians should be familiar with these services, as well as all Task Force D recommendations, and avoid recommending them or providing them. High quality preventive care involves both providing services of proven benefit and avoiding those that do not.

Over the past year through early 2019, the US Preventive Services Task Force made 34 recommendations on 19 different topics. Twenty-six were reaffirmations of recommendations made in previous years (TABLE 1¹); the Task Force attempts to reassess topics every 7 years. Two new topics were addressed with 2 new recommendations, and 6 previous recommendations were revised or reversed (TABLE 2^2-9).

This Practice Alert discusses the new and the changed recommendations. (In 2018, the Practice Alert podcast series covered screening for ovarian cancer [April], prostate cancer [June], and cervical cancer [October], and EKG screening for cardiovascular disease [November].) All current Task Force recommendations are available on the USPSTF Web site.¹

New topics

Perinatal depression prevention

The Task Force recommends that clinicians counsel pregnant women and women in the first year postpartum who are at increased risk for perinatal depression, or refer for such services. The recommendation applies to those who are not diagnosed with depression but are at increased risk.

Perinatal depression can negatively affect both mother and child in several ways and occurs at a rate close to 9% during pregnancy and 37% during the first year postpartum.² The interventions studied by the Task Force included cognitive behavioral therapy and interpersonal therapy; most sessions were initiated in the second trimester of pregnancy and varied in number of sessions and intensity. The Task Force includes the following in the list of risks that should prompt a referral: a history of depression, current depressive symptoms that fall short of that needed for a depression diagnosis, low income, adolescent or single parenthood, recent intimate partner violence, elevated anxiety symptoms, physical or sexual abuse, or a history of significant negative life events. (See “Postpartum anxiety: More common than you think,” in the April issue.)

Atrial fibrillation

The Task Force found insufficient evidence to recommend for or against the use of electrocardiography (EKG) to screen for atrial fibrillation (AF).³ Atrial fibrillation is common, affecting 3% of men and 2% of women between the ages of 65 and 69 years, and it increases in prevalence with age.⁴ It is a major risk factor for stroke, although it is commonly first diagnosed after a stroke. Treatment with anticoagulant therapy reduces the incidence of stroke in patients with symptomatic AF, but this treatment is associated with the risk of major bleeding. The problem in screening for AF with EKG is that it is associated with misdiagnosis, over-treatment, and further testing. The Task Force could not find any direct evidence of the totality of benefits and harms of screening asymptomatic adults with EKG, and it raised the possibility that benefit with less harm might be achieved by screening with pulse palpation and heart auscultation, followed by EKG testing of those with an irregular pulse.

Revisions of previous recommendations

Cervical cancer screening

The Task Force continues to recommend screening for cervical cancer in women 21 to 65 years of age.⁵ The major change in the current recommendation is for women ages 30 to 65 years. For this group, the Task Force now recommends screening every 5 years with high-risk human papillomavirus (hrHPV) testing alone as a possible alternative to screening every 3 years with cytology alone. They also halfheartedly endorse co-testing as an option, even though it may result in more tests and procedures compared with either cytology or hrHPV testing alone, with equal effectiveness. For women ages 21 to 29 years, cervical cytology alone every 3 years is still the only recommended regimen.

CASE

A 22-year-old active-duty man presented with left hallux pain, which he had experienced for several years due to an “ingrown toenail.” During the 3 to 4 months prior to presentation, his pain had progressed to the point that he had difficulty with weight-bearing activities. Several weeks prior to evaluation, he tried removing a portion of the nail himself with nail clippers and a pocket knife, but the symptoms persisted.

A skin exam revealed inflamed hypertrophic skin on the medial and lateral border of the toenail without exudate (FIGURE 1A). The patient was given a diagnosis of recurrent onychocryptosis without paronychia. He reported having a similar occurrence 1 to 2 years earlier, which had been treated by his primary care physician via total nail avulsion.

How would you proceed with his care?

Onychocryptosis, also known as an ingrown toenail, is a relatively common condition that can be treated with several nonsurgical and surgical approaches. It occurs when the nail plate punctures the periungual skin, usually on the hallux. Onychocryptosis may be caused by close-trimmed nails with a free edge that are allowed to enter the lateral nail fold. This results in a cascade of inflammatory and infectious processes and may result in paronychia. The inflamed toe skin will often grow over the lateral nail, which further exacerbates the condition. Mild to moderate lesions have limited pain, redness, and swelling with little or no discharge. Moderate to severe lesions have significant pain, redness, swelling, discharge, and/or persistent symptoms despite appropriate conservative therapies.

The condition may manifest at any age, although it is more common in adolescents and young adults. Onychocryptosis is slightly more common in males.¹ It may present as a chief complaint, although many cases will likely be discovered incidentally on a skin exam. Although there is no firm evidence of causative factors, possible risk factors include tight-fitting shoes, repetitive activities/sports, poor foot hygiene, hyperhidrosis, genetic predisposition, obesity, and lower-extremity edema.² Patients often exacerbate the problem with home treatments designed to trim the nail as short as possible. Comparison of symptomatic vs control patients has failed to demonstrate any systematic difference between the nails themselves. This suggests that treatment may not be effective if it is simply directed at controlling nail abnormalities.^3,4

Conservative therapy

Conservative therapy should be considered first-line treatment for mild to moderate cases of onychocryptosis. The following are conservative therapy options.⁵

Proper nail trimming. Advise the patient to allow the nail to grow past the lateral nail fold and to keep it trimmed long so that the overgrowing toe skin cannot encroach on the free edge of the nail. The growth rate of the toenail is approximately 1.62 mm/month—something you may want to mention to the patient so that he or she will have a sense of the estimated duration of therapy.⁶ Also, the patient may need to implement the following other measures, while the nail is allowed to grow.

Continue to: Skin-softening techniques

Skin-softening techniques. Encourage the patient to apply warm compresses or to soak the toe in warm water for 10 to 20 minutes a day.

Barriers may be inserted between the nail and the periungual skin. Daily intermittent barriers may be used to lift the nail away from the lateral nail fold during regular hygiene activities. Tell the patient that a continuous barrier may be created using gauze or any variety of dental floss placed between the nail and the lateral nail fold, then secured in place with tape and changed daily.

Gutter splint. The gutter splint consists of a plastic tube that has been slit longitudinally from bottom to top with iris scissors or a scalpel. One end is then cut diagonally for smooth insertion between the nail edge and the periungual skin. When placed, the gutter splint lies longitudinally along the edge of the nail, providing a barrier to protect the toe during nail growth. The tube may be obtained by trimming a sterilized vinyl intravenous drip infusion, the catheter from an 18-gauge or larger needle (with the needle removed), or a filter straw. This tube can be affixed with adhesive tape, sutures, or cyanoacrylate.⁷

Patient-controlled taping. An adhesive tape such as 1-inch silk tape is placed on the symptomatic edge of the lateral nail fold and traction is applied. The tape is then wrapped around the toe and affixed such that the lateral nail fold is pulled away from the nail.⁸

Medications. Many practitioners use high-potency topical steroids, although evidence for their effectiveness is lacking. Oral antibiotics are unnecessary.

Continue to: One disadvantage of conservative therapy is...

Conservative therapies focus on allowing the nail to grow past the lateral nail fold and keeping it trimmed long so that the overgrowing toe skin can’t encroach on the free edge of the nail.

One disadvantage of conservative therapy is that the patient must wait for nail growth before symptom resolution is achieved. In cases where the patient requires immediate symptom resolution, surgical therapies can be used (such as nail edge excision).

Surgical therapy

Surgery is more effective than nonsurgical therapies in preventing recurrence^2,9 and is indicated for severe cases of onychocryptosis or for patients who do not respond to a trial of at least 3 months of conservative care.

While there are no universally accepted contraindications to surgical toenail procedures, caution should be taken with patients who have poor healing potential of the feet (eg, chronic vasculopathy or neuropathy). That said, when patients with diabetes have undergone surgical toenail procedures, the research indicates that they have not had worse outcomes.^10,11

Approximately 6 weeks after the Vandenbos procedure, the wound should be healed completely with the nail remaining above the skin.

The following options for surgical therapy of onychocryptosis are considered safe; however, each has variable effectiveness. Each procedure should be performed under local anesthesia, typically as a digital nerve block. The toe should be cleansed prior to any surgical intervention, and clean procedure precautions should be employed. Of the procedures listed here, only phenolization and the Vandenbos procedure are considered definitive treatments for onychocryptosis.⁵

Total nail removal without matricectomy. In this procedure, the nail is removed entirely, but the nail matrix is not destroyed. The nail regrows in the same dimensions as it had previously, but during the time it is absent the nail bed tends to contract longitudinally and transversely, increasing the likelihood that new nail growth will cause recurrence of symptoms.⁵ Due to a recurrence rate of > 70%, total nail removal without matricectomy is not recommended as monotherapy for ingrown toenails.⁹

Continue to: Nail edge excision without mactricectomy

Nail edge excision without matricectomy. This procedure involves removing one-quarter to one-third of the nail from the symptomatic edge. This procedure takes little time and is easy to perform. Recurrence rates are > 70% for the same reasons as outlined above.⁹ (Often during preparation for this procedure, a loose shard of nail is observed puncturing the periungual skin. Removal of this single aberrant portion of nail is frequently curative in and of itself.) Patients typically report rapid relief of symptoms, so this procedure may be favored when patients do not have the time or desire to attempt more definitive therapy. However, patients should be advised of the high recurrence rate.

Nail excision with matricectomy using phenol (ie, phenolization). In this procedure, the nail is avulsed, and the matrix is destroyed with phenol (80%-88%).^9,12 Typically, this is performed only on the symptomatic edge of the nail. The phenol should be applied for 1 to 3 minutes using a cotton-tipped applicator saturated in the solution. Recurrence rates are as low as 2% when the phenol is applied for 3 minutes, although the risk for symptomatic drainage of the wound after 2 weeks is > 50%. When applied for only 1 minute, the recurrence rate is approximately 12% but the risk for drainage at 2 weeks is also 12%.¹² (Other studies have reported recurrence rates up to 50%.¹³)

Surgical therapies are indicated for severe cases of onychocryptosis or for those who do not respond to a 3-month trial of conservative care.

While phenolization is relatively quick and simple—and is associated with good cure rates—it causes pain and disability during the healing process and takes several weeks to heal. Phenolization also has a slightly increased risk for infection when compared to nail excision without matricectomy. Giving antibiotics before or following the procedure does not appear to reduce this risk.⁷ If the matrix is incompletely destroyed, a new nail spicule may grow along the lateral nail edge and a repeat procedure may be required.⁷ When properly performed, the nail will be narrower but should otherwise maintain a more-or-less normal appearance. The use of phenolization for the treatment of onychocryptosis in the pediatric population has been found to be successful, as well.¹⁴

The Vandenbos procedure. This procedure involves removing a large amount of skin from the lateral nail fold and allowing it to heal secondarily. When performed correctly, this procedure has a very low recurrence rate, with no cases of recurrence in nearly 1200 patients reported in the literature.¹⁵ The cosmetic results are generally superior to the other surgical methods described here⁵ and patient satisfaction is high.¹⁵ It has been used with similar effectiveness in children.¹⁶

The Vandenbos procedure can definitively treat onychocryptosis with a good cosmetic outcome.

Full recovery takes about 6 weeks. Overall, the Vandenbos procedure can definitively treat the condition with a good cosmetic outcome. (See “How to perform the Vandenbos procedure.”)

In this procedure, the nail is avulsed, and the matrix is destroyed with phenol (80%-88%).^9,12 Typically, this is performed only on the symptomatic edge of the nail. The phenol should be applied for 1 to 3 minutes using a cotton-tipped applicator saturated in the solution. Recurrence rates are as low as 2% when the phenol is applied for 3 minutes, although the risk for symptomatic drainage of the wound after 2 weeks is > 50%. When applied for only 1 minute, the recurrence rate is approximately 12% but the risk for drainage at 2 weeks is also 12%.¹² (Other studies have reported recurrence rates up to 50%.¹³)

Surgical therapies are indicated for severe cases of onychocryptosis or for those who do not respond to a 3-month trial of conservative care.

While phenolization is relatively quick and simple—and is associated with good cure rates—it causes pain and disability during the healing process and takes several weeks to heal. Phenolization also has a slightly increased risk for infection when compared to nail excision without matricectomy. Giving antibiotics before or following the procedure does not appear to reduce this risk.⁷ If the matrix is incompletely destroyed, a new nail spicule may grow along the lateral nail edge and a repeat procedure may be required.⁷ When properly performed, the nail will be narrower but should otherwise maintain a more-or-less normal appearance. The use of phenolization for the treatment of onychocryptosis in the pediatric population has been found to be successful, as well.¹⁴

The Vandenbos procedure. This procedure involves removing a large amount of skin from the lateral nail fold and allowing it to heal secondarily. When performed correctly, this procedure has a very low recurrence rate, with no cases of recurrence in nearly 1200 patients reported in the literature.¹⁵ The cosmetic results are generally superior to the other surgical methods described here⁵ and patient satisfaction is high.¹⁵ It has been used with similar effectiveness in children.¹⁶

The Vandenbos procedure can definitively treat onychocryptosis with a good cosmetic outcome.

Full recovery takes about 6 weeks. Overall, the Vandenbos procedure can definitively treat the condition with a good cosmetic outcome. (See “How to perform the Vandenbos procedure.”)

CASE

A 22-year-old active-duty man presented with left hallux pain, which he had experienced for several years due to an “ingrown toenail.” During the 3 to 4 months prior to presentation, his pain had progressed to the point that he had difficulty with weight-bearing activities. Several weeks prior to evaluation, he tried removing a portion of the nail himself with nail clippers and a pocket knife, but the symptoms persisted.

A skin exam revealed inflamed hypertrophic skin on the medial and lateral border of the toenail without exudate (FIGURE 1A). The patient was given a diagnosis of recurrent onychocryptosis without paronychia. He reported having a similar occurrence 1 to 2 years earlier, which had been treated by his primary care physician via total nail avulsion.

How would you proceed with his care?

Onychocryptosis, also known as an ingrown toenail, is a relatively common condition that can be treated with several nonsurgical and surgical approaches. It occurs when the nail plate punctures the periungual skin, usually on the hallux. Onychocryptosis may be caused by close-trimmed nails with a free edge that are allowed to enter the lateral nail fold. This results in a cascade of inflammatory and infectious processes and may result in paronychia. The inflamed toe skin will often grow over the lateral nail, which further exacerbates the condition. Mild to moderate lesions have limited pain, redness, and swelling with little or no discharge. Moderate to severe lesions have significant pain, redness, swelling, discharge, and/or persistent symptoms despite appropriate conservative therapies.

The condition may manifest at any age, although it is more common in adolescents and young adults. Onychocryptosis is slightly more common in males.¹ It may present as a chief complaint, although many cases will likely be discovered incidentally on a skin exam. Although there is no firm evidence of causative factors, possible risk factors include tight-fitting shoes, repetitive activities/sports, poor foot hygiene, hyperhidrosis, genetic predisposition, obesity, and lower-extremity edema.² Patients often exacerbate the problem with home treatments designed to trim the nail as short as possible. Comparison of symptomatic vs control patients has failed to demonstrate any systematic difference between the nails themselves. This suggests that treatment may not be effective if it is simply directed at controlling nail abnormalities.^3,4

Conservative therapy

Conservative therapy should be considered first-line treatment for mild to moderate cases of onychocryptosis. The following are conservative therapy options.⁵

Proper nail trimming. Advise the patient to allow the nail to grow past the lateral nail fold and to keep it trimmed long so that the overgrowing toe skin cannot encroach on the free edge of the nail. The growth rate of the toenail is approximately 1.62 mm/month—something you may want to mention to the patient so that he or she will have a sense of the estimated duration of therapy.⁶ Also, the patient may need to implement the following other measures, while the nail is allowed to grow.

Continue to: Skin-softening techniques

Skin-softening techniques. Encourage the patient to apply warm compresses or to soak the toe in warm water for 10 to 20 minutes a day.

Barriers may be inserted between the nail and the periungual skin. Daily intermittent barriers may be used to lift the nail away from the lateral nail fold during regular hygiene activities. Tell the patient that a continuous barrier may be created using gauze or any variety of dental floss placed between the nail and the lateral nail fold, then secured in place with tape and changed daily.

Gutter splint. The gutter splint consists of a plastic tube that has been slit longitudinally from bottom to top with iris scissors or a scalpel. One end is then cut diagonally for smooth insertion between the nail edge and the periungual skin. When placed, the gutter splint lies longitudinally along the edge of the nail, providing a barrier to protect the toe during nail growth. The tube may be obtained by trimming a sterilized vinyl intravenous drip infusion, the catheter from an 18-gauge or larger needle (with the needle removed), or a filter straw. This tube can be affixed with adhesive tape, sutures, or cyanoacrylate.⁷

Patient-controlled taping. An adhesive tape such as 1-inch silk tape is placed on the symptomatic edge of the lateral nail fold and traction is applied. The tape is then wrapped around the toe and affixed such that the lateral nail fold is pulled away from the nail.⁸

Medications. Many practitioners use high-potency topical steroids, although evidence for their effectiveness is lacking. Oral antibiotics are unnecessary.

Continue to: One disadvantage of conservative therapy is...

Conservative therapies focus on allowing the nail to grow past the lateral nail fold and keeping it trimmed long so that the overgrowing toe skin can’t encroach on the free edge of the nail.

One disadvantage of conservative therapy is that the patient must wait for nail growth before symptom resolution is achieved. In cases where the patient requires immediate symptom resolution, surgical therapies can be used (such as nail edge excision).

Surgical therapy

Surgery is more effective than nonsurgical therapies in preventing recurrence^2,9 and is indicated for severe cases of onychocryptosis or for patients who do not respond to a trial of at least 3 months of conservative care.

While there are no universally accepted contraindications to surgical toenail procedures, caution should be taken with patients who have poor healing potential of the feet (eg, chronic vasculopathy or neuropathy). That said, when patients with diabetes have undergone surgical toenail procedures, the research indicates that they have not had worse outcomes.^10,11

Approximately 6 weeks after the Vandenbos procedure, the wound should be healed completely with the nail remaining above the skin.

The following options for surgical therapy of onychocryptosis are considered safe; however, each has variable effectiveness. Each procedure should be performed under local anesthesia, typically as a digital nerve block. The toe should be cleansed prior to any surgical intervention, and clean procedure precautions should be employed. Of the procedures listed here, only phenolization and the Vandenbos procedure are considered definitive treatments for onychocryptosis.⁵

Total nail removal without matricectomy. In this procedure, the nail is removed entirely, but the nail matrix is not destroyed. The nail regrows in the same dimensions as it had previously, but during the time it is absent the nail bed tends to contract longitudinally and transversely, increasing the likelihood that new nail growth will cause recurrence of symptoms.⁵ Due to a recurrence rate of > 70%, total nail removal without matricectomy is not recommended as monotherapy for ingrown toenails.⁹

Continue to: Nail edge excision without mactricectomy

Nail edge excision without matricectomy. This procedure involves removing one-quarter to one-third of the nail from the symptomatic edge. This procedure takes little time and is easy to perform. Recurrence rates are > 70% for the same reasons as outlined above.⁹ (Often during preparation for this procedure, a loose shard of nail is observed puncturing the periungual skin. Removal of this single aberrant portion of nail is frequently curative in and of itself.) Patients typically report rapid relief of symptoms, so this procedure may be favored when patients do not have the time or desire to attempt more definitive therapy. However, patients should be advised of the high recurrence rate.

Nail excision with matricectomy using phenol (ie, phenolization). In this procedure, the nail is avulsed, and the matrix is destroyed with phenol (80%-88%).^9,12 Typically, this is performed only on the symptomatic edge of the nail. The phenol should be applied for 1 to 3 minutes using a cotton-tipped applicator saturated in the solution.

Surgical therapies are indicated for severe cases of onychocryptosis or for those who do not respond to a 3-month trial of conservative care.

While phenolization is relatively quick and simple—and is associated with good cure rates—it causes pain and disability during the healing process and takes several weeks to heal. Phenolization also has a slightly increased risk for infection when compared to nail excision without matricectomy. Giving antibiotics before or following the procedure does not appear to reduce this risk.⁷ If the matrix is incompletely destroyed, a new nail spicule may grow along the lateral nail edge and a repeat procedure may be required.⁷ When properly performed, the nail will be narrower but should otherwise maintain a more-or-less normal appearance.

Female patients with acne may benefit from continuing treatment with spironolactone longer than with oral antibiotics, according to a retrospective study of women with acne published in the Journal of the American Academy of Dermatology.

VladimirFLoyd/Thinkstock

Among those treated for at least a year, patients continued spironolactone for about 90 days longer on average, than those on antibiotic therapy, reported John S. Barbieri, MD, of the department of dermatology at the University of Pennsylvania, Philadelphia, and associates. “The extended drug usage survival of spironolactone suggests that, in routine clinical practice, spironolactone may have good long-term effectiveness and tolerability,” they wrote. “Since female patients often have persistent acne into adulthood and given concerns regarding antibiotic overuse among acne patients, it is possible that using spironolactone as a first-line agent before oral antibiotics could improve outcomes for female patients with acne,” they added.

In the study, they pointed out that spironolactone is emerging as a possible alternative to oral antibiotic therapy, but “little is known about long-term outcomes with spironolactone for those who have an initial positive response and how it compares to other alternatives.”

To examine the duration of acne treatment with spironolactone versus oral antibiotics, the researchers analyzed data during 2010-2016 in the Optum Clinformatics Data Mart. They included data on female patients aged 12-40 years, with at least two diagnosis codes for acne, who received spironolactone or oral antibiotics for at least 12 months. They used multivariate Cox proportional hazard models to assess differences in duration of therapy for spironolactone, compared with oral antibiotics.

The mean duration of a treatment course was significantly longer among the 4,321 patients treated with spironolactone than among the 7,517 patients treated with oral tetracycline-class antibiotics (697.8 days vs. 604.4 days; P less than .001). Compared with treatment with oral tetracyclines, the hazard ratio for discontinuing spironolactone treatment was 0.74, after researchers controlled for the age at diagnosis and treatment, history of polycystic ovarian syndrome, and history of combined oral contraceptive or topical retinoid treatment.

Patients who receive spironolactone and patients who receive oral antibiotics may represent different populations, the authors noted. In addition, guidelines advise limiting antibiotic treatment to 3-6 months, and antibiotic discontinuations may have been related to these recommendations. “It is not possible to determine whether medication discontinuation occurred due to lack of efficacy, cost, side effects, resolution of acne, or other factors,” they said, adding that prospective studies are needed “to identify the optimal treatment approaches for female patients with moderate to severe acne.”

The study was funded in part by the National Institute of Arthritis and Musculoskeletal and Skin Diseases.
