Unmet dental needs and untreated dental decay represent a significant disease burden for children and adults.

There are 2 leading types of dental diseases: tooth decay (dental caries or cavities) and gum disease (periodontal disease). Tooth decay is by far the more prevalent of the 2, causing a greater, needless loss in the quality of life.

Prevalence of Tooth Decay

Dental caries is a major public health problem. Even though in the past 50 years there has been a significant decline in dental caries, it is the most common ailment in the U.S., and large segments of the population experience various barriers to care. Among children and adolescents, dental caries is 4 to 5 times more common than asthma.1,2 Data from the National Health and Nutrition Examination Survey, 2011-2012, show that among children aged 2 to 8 years, 37% had dental caries in their primary teeth. Among adolescents aged 12 to 19 years, the prevalence of dental caries in the permanent teeth was 58%. About 90% of adults aged ≥ 20 years had dental caries.3,4

Unmet Dental Needs

The real disease burden of dental caries is the amount of unmet needs or untreated decay. In recent years, there has been a shift in the peak prevalence of untreated tooth decay from children to adults, possibly attributable to socioecologic factors.3,5 The prevalence of untreated decay in children and adolescents was about 15%. However, the prevalence of untreated decay among adults aged 20 to 64 years was higher: 27% of the adults had decayed teeth that were left untreated.3,4

The rates of untreated decay among these adults were higher among Hispanics (36%) and non-Hispanic blacks (42%) than among non-Hispanic whites (22%) and non-Hispanic Asians (17%).3,4 Despite the decline in dental caries, disparities persist among different racial, ethnic, educational, and income groups; it remains a modern curse for large segments of the population.

Basics of Tooth Decay

Tooth decay is caused by Streptococcus mutans (S mutans) bacterial infection. The cariogenic bacteria are transmissible from mother or caregiver to children.6 After tooth eruption, the mouth is quickly colonized by S mutans. Even though the bacteria are ubiquitous, the disease burden is more concentrated in some populations.

What makes some people more susceptible to tooth decay? Contrary to popular belief, it is not caused by childbirth or low dietary intake of calcium.7,8 Tooth decay typically starts on the chewing surfaces or proximal contacts of teeth.

S mutans is introduced into the mouth principally from another person. The bacteria colonize the mouth and with the formation of plaques, adhere to the teeth. Plaque is the soft, sticky film formed on teeth from food degradation. The biofilm is conducive to bacterial proliferation and teeming with bacteria.

The S mutans bacteria break down sugars and produce lactic acids, which cause tooth decay—a process of demineralization, or loss of calcium phosphate, from the tooth structure.2,9 As a result, the tooth “softens” and eventually collapses on itself, forming a cavity. Tooth decay most commonly occurs at the occlusal (chewing) surfaces and the proximal contacts of teeth. The occlusal aspects of teeth have a natural pit-and-fissure morphology that facilitates bacterial adherence and colonization. The proximal contacts of teeth also facilitate adherence of plaque and bacteria.

A tooth is made up of 3 layers. The outermost layer of the tooth crown is the enamel, which is the hardest or most mineralized part of the tooth—it is harder than bone. The next layer is the dentin, which has a higher percentage of organic material (collagen) and water than the enamel has and is softer. In the center of the tooth is the pulp (consisting of nerves and blood vessels), which keeps the tooth alive and provides sensation to the tooth. The outermost layer of the tooth root is cementum (instead of enamel), followed by dentin, which encases the pulp tissues contained within the root canals (Figure).

Process of Tooth Loss

At the early stage of tooth decay, when the decay is confined to the enamel, the tooth is asymptomatic, and the damage is reversible. When the decay extends into the dentin, restorations are a consideration. The further the decay extends toward the pulp, the greater the risk of tooth sensitivity and pain. Decay naturally progresses faster in the (less mineralized) dentin than when the decay is still confined to the enamel. If left unchecked, the decay may progress, and the bacteria eventually invade the pulp. At that point, there is risk of not only pain, but also swelling and tooth loss.

At the earlier stage of decay, a tooth may be treated with restorations, which are typically made of dental amalgam, resin (composite), glass ionomer, porcelain, or gold. When the bacteria have invaded the pulp, a dental restoration will not treat the pain and infection. Root canal therapy is needed to remove the infected tissues in the pulp chamber and root canals. Further, if the tooth is too compromised with extensive destruction from the decay or if there are financial or other barriers to root canal therapy, extraction is likely the only option.

 

 

Key to Oral Health

Personal daily oral hygiene (brushing and flossing) helps remove plaque from accumulating on tooth surfaces—especially the occlusal surfaces and proximal contacts, which are most prone to decay. Brushing teeth is of limited benefit without the use of fluoride toothpaste.8 The most important time for brushing is before bedtime, because less salivation occurs during sleep. Saliva helps clear fermented bacterial products, buffers the drop in pH, prevents demineralization, and enhances remineralizaton.10

Fluoride benefits children and adults of all ages, and comes in the form of fluoridated tap water, toothpaste, mouth rinse, and professionally applied gel and varnish. Fluoride occurs naturally in the environment, too. Its effect is mainly topical—fluoride gets incorporated into the tooth as fluorapatite, replacing the hydroxyapatite. Fluorapatite is harder than the hydroxyapatite; hence, the tooth is better able to resist demineralization by bacterial acid attacks.11 Professionally applied fluoride is generally recommended for high-risk patients, typically patients with high caries burden, ie, many decayed teeth. The best predictor of future caries is the past caries experience.

Sealants are thin, plastic coatings that are painted on to tooth occlusal surfaces, obliterating the pits and fissures normally found on posterior teeth. The smooth sealants effectively inhibit the colonization of S mutans on the occlusal aspects of teeth.12 Sealants are applied in dental offices (by the dentists or dental hygienists) or in school-based programs.

Longer hospitalization, greater care needed for depressed ischemic stroke patients

Article Type

– Patients admitted with acute ischemic stroke (AIS) with preexisting major depressive disorder (MDD) are less likely to die while in the hospital but are often hospitalized longer and are more likely to need specialty care when they are discharged, in comparison to similar patients without depression in the National Inpatient Sample.

Dr. Arpita Hazra
The influence of MDD following a stroke on patient outcome has been well studied. However, the influence of preexisting MDD on immediate and longer-term outcomes of AIS is unclear. To provide clarity, Dr. Hazra and her colleagues used recent data from more than 4.3 million hospital AIS-related admissions identified in the United States between 2002 and 2012 in the National Inpatient Sample. Nearly 372,000 (8.6%) of the patients had MDD, and the proportion of MDD-related cases rose from 6.4% in 2002 to 10.3% in 2012. The researchers acknowledged that this may not actually represent a real increase. It might reflect, at least in part, the increasing use of the diagnostic ICD-9-CM codes in that decade.

Thrombolysis was carried out in fewer depressed patients than in those without depression (3.8% vs. 4.8%; P less than .001). The odds of death during hospitalization were 36% less for patients with MDD. However, patients with MDD tended to be hospitalized longer than nondepressed patients (median 3.6 vs. 3.4 days; P less than .001) and were nearly 40% more likely to require specialty care following discharge.

“There is a need to explore the reasons behind this disparity in outcomes and thrombolysis utilization in order to improve poststroke outcome in this vulnerable population,” Dr. Hazra said.

At face value, the observation of decreased mortality in AIS patients with preexisting MDD was surprising, according to Dr. Hazra. She suggested that this may reflect prior hospital treatment for these patients, because of other comorbidities associated with depression.

Dr. Hazra reported having no financial disclosures.

However, patients with MDD tended to be hospitalized longer than nondepressed patients (median 3.6 vs. 3.4 days; P less than .001) and were nearly 40% more likely to require specialty care following discharge.

“There is a need to explore the reasons behind this disparity in outcomes and thrombolysis utilization in order to improve poststroke outcome in this vulnerable population,” Dr. Hazra said.

At face value, the observation of decreased mortality in AIS patients with preexisting MDD was surprising, according to Dr. Hazra. She suggested that this may reflect prior hospital treatment for these patients, because of other comorbidities associated with depression.

Dr. Hazra reported having no financial disclosures.

 

– Patients admitted with acute ischemic stroke (AIS) with preexisting major depressive disorder (MDD) are less likely to die while in the hospital but are often hospitalized longer and are more likely to need specialty care when they are discharged, in comparison to similar patients without depression in the National Inpatient Sample.

Dr. Arpita Hazra
The influence of MDD following a stroke on patient outcome has been well studied. However, the influence of preexisting MDD on immediate and longer-term outcomes of AIS is unclear. To provide clarity, Dr. Hazra and her colleagues used recent data from more than 4.3 million hospital AIS-related admissions identified in the United States between 2002 and 2012 in the National Inpatient Sample. Nearly 372,000 (8.6%) of the patients had MDD, and the proportion of MDD-related cases rose from 6.4% in 2002 to 10.3% in 2012. The researchers acknowledged that this may not actually represent a real increase. It might reflect, at least in part, the increasing use of the diagnostic ICD-9-CM codes in that decade.

Key clinical point: Major depressive disorder in patients hospitalized with acute ischemic stroke decreases the risk of death but increases risk of morbidity.

Major finding: In-hospital mortality was significantly lower for depressed patients with acute ischemic stroke, compared with nondepressed patients, but depressed patients had a significantly longer length of hospitalization and higher rate of discharge to specialty care.

Data source: Study of 4.3 million hospital AIS-related admissions identified in the United States during 2002-2012 in the National Inpatient Sample.

OAK: Atezolizumab grows OS in advanced NSCLC

Article Type
Changed

 

– The checkpoint inhibitor atezolizumab improved overall survival of advanced non–small-cell lung cancer, compared with docetaxel, primary analysis from the OAK trial shows.

Dr. Fabrice Barlesi
“Atezolizumab was well tolerated with a favorable safety profile compared to docetaxel. No new safety signals were identified, and the rate of immune-mediated adverse events was very low,” he said at the European Society for Medical Oncology Congress.

Atezolizumab was previously shown in the phase II POPLAR trial to significantly increase overall survival compared with docetaxel in second- or third-line therapy in patients with locally advanced or metastatic NSCLC who had disease progression after platinum-based chemotherapy.

The OAK trial investigators enrolled 1,225 patients with locally advanced or metastatic NSCLC following one or two prior lines of therapy that contained at least one platinum-based regimen. The patients could have any degree of PD-L1 expression.

Dr. Barlesi presented results of a prespecified intention-to-treat analysis of the first 850 patients enrolled.

Following stratification for PD-L1, histology, and prior chemotherapy regimens, they were randomly assigned to either atezolizumab 1,200 mg IV every 3 weeks or docetaxel 75 mg/m2 every 3 weeks. In the atezolizumab arm, therapy could be continued until disease progression or clinical benefit. In the docetaxel arm, therapy was continued until progression.

As noted, atezolizumab was associated with significantly better OS, the primary endpoint (13.8 vs. 9.6 months) with a hazard ratio (HR) of 0.73 (P = .0003). OS rates at 12 months were 55% in the atezolizumab arm vs. 41% in the docetaxel arm, and at 18 months the rates were 40% and 27%, respectively.

The investigators found that atezolizumab provided a benefit regardless of PD-L1 expression, with a hazard ratio of 0.74 (P = .0102) for the 55% of patients with PD-L1 expression on at least 1% of their tumor cells, and 0.75 (P = .0205) for patients with PD-L1 on less than 1% of tumor cells.

Median overall survival was greater with both drugs for patients with higher levels of PD-L1 expression, with a median of 15.7 months for those treated with atezolizumab and 10.3 months for those treated with docetaxel. In contrast, the respective median overall survival durations in the patients with less than 1% PD-L1 expression were 12.6 and 8.9 months.

The greatest benefit for atezolizumab was seen in patients with PD-L1 expression of 50% or more of tumor cells or 10% or more of tumor-infiltrating immune cells, with a median OS at a minimum follow-up of 19 months of 20.5 months vs. 8.9 months, translating into a hazard ratio for atezolizumab of 0.41 (P less than .0001).

An analysis of OS by histology showed HRs of 0.73 for atezolizumab for patients with either non-squamous tumors (P = .0015) or squamous tumors (P = .0383). In addition, an analysis of OS in selected subgroups showed a trend favoring atezolizumab in patients who had never smoked, who tend to have a worse prognosis than would current or former smokers.

In an analysis of progression-free survival, there was no significant difference between the groups (median 4.0 vs. 2.8 months).

Adverse events of grade 3 or greater of any cause were lower with atezolizumab, at 37% vs. 54%. There was one treatment-related death from respiratory infection in a patient who received docetaxel.

Invited discussant Naiyer Rizvi, MD, an oncologist at Columbia University Medical Center in New York, said that the OAK trial confirms that atezolizumab is an appropriate second-line therapy for unselected patients with advanced NSCLC, and should be explored for its potential survival benefits in never smokers.

Tryptase gene variant linked to GI, joint, and skin symptoms

Article Type
Changed

 

Researchers have identified a genetic variant associated with inherited elevated basal serum tryptase levels and linked to a distinct group of comorbid multisystem complaints.

These features, including cutaneous flushing, certain chronic pain disorders, autonomic dysfunction, and gastrointestinal dysmotility, have been reported in association with genetic disorders or joint hypermobility syndromes such as Ehlers-Danlos syndrome type III (hypermobility type, EDS III) and often follow a dominant inheritance pattern in affected families, providing a reason to look into a genetic basis for these patient characteristics, according to Jonathan J. Lyons, MD, of the National Institute of Allergy and Infectious Diseases, and his coauthors. The researchers reported their findings Oct. 17 in Nature Genetics.

“Recently, we and others described family cohorts with symp­tom complexes conforming to these functional presentations but found them in association uniquely with elevated basal serum lev­els of tryptase – a mast cell mediator commonly used to assist in the diagnosis of mast cell–associated diseases,” they wrote. “Because elevated basal serum tryptase levels without mastocytosis is a relatively common trait in the general population and in one report has been associated with functional symptoms, we set out to identify the genetic cause for elevated tryptase levels and to characterize associated clinical phenotypes in these families and in unselected individuals.”

The researchers recruited 96 individuals from 35 families with a syndrome of elevated basal serum tryptase levels and multiple comorbid symptoms following an autosomal dominant pattern of inheritance.

These symptoms included gastrointestinal dys­motility such as irritable bowel syndrome or chronic gastroesophageal reflux, connective tissue abnormalities such as joint hypermobility, congenital skeletal abnormalities, retained primary dentition, symptoms suggestive of autonomic dysfunction such as postural orthostatic tachycardia syndrome, and elevated composite autonomic symptom scores. Other symptoms included recurrent cutaneous flushing and pruritus – often associated with urticaria and complaints of sleep disruption – and systemic reaction to stinging insects.

Using exome and genome sequencing followed by linkage analysis, researchers identified duplications and triplications within the TPSAB1 gene encoding alpha-tryptase (Nat Genet. 2016 Oct 17. doi: 10.1038/ng.3696). Further analysis found elevated alpha-tryptase/beta-tryptase ratios among affected family members and suggested that multiple copies of the alpha-tryptase sequence were inherited together.

To confirm the finding, researchers examined genetic data from a cohort of healthy unrelated volunteers in the National Human Genome Research Institute ClinSeq cohort, which identified 125 samples with partially enriched duplication of alpha tryptase–encoding sequence using a common haplotype.

Of these, three individuals had single-allele duplications of the alpha tryptase–encoding sequence and also presented with similar symptoms to the original cohort: cutaneous flushing, itching, or hives, systemic venom reactions, irritable bowel syndrome, retained primary dentition, and elevated autonomic symptom scores.

“We have found that this phenotype is most frequently inher­ited in an autosomal dominant manner and that, when this occurs, it is exclusively associated with increased copy number on a single allele of alpha tryptase–encoding sequence in the TPSAB1 gene, a genetic trait we have termed hereditary alpha-tryptasemia,” the researchers reported. “The families studied in our initial cohort likely represent the most severe phenotypes among individuals affected with hereditary alpha-tryptasemia, owing in part to the lack of detection of triplication of alpha tryptase–encoding sequence in unselected populations, which we have tentatively designated as hereditary alpha-tryptasemia syndrome.”

The authors suggested that part of the clinical presentation of this syndrome included symptoms that may be associated clinically with mast cell mediator release. In the context of elevated basal serum tryptase levels, this might prompt a doctor to investigate for clonal mast cell disease, which would include bone-marrow biopsy.

However, given that such an investigation would be challenging, and given that elevated tryptase levels are not uncommon in the generally population, they suggested tryptase genotyping may be warranted.

The study was supported by the National Institute of Allergy and Infectious Diseases, the ARTrust/the Mastocytosis Society, and the National Human Genome Research Institute. One author declared royalties associated with the tryptase UniCAP assay, and consulting fees from Genentech. Another author declared an advisory position and royalties from private industry.

Quality of outpatient care has not improved consistently since 2002

Limitations in study methodology
Article Type
Changed

 

The clinical quality of outpatient care for adults in the United States did not improve consistently from 2002 to 2013, despite numerous local, regional, and national efforts to make it better, according to a report published online Oct. 17 in JAMA Internal Medicine.

Body

 

The study by Levine et al. had several limitations, so we still cannot say how good the overall quality of health care was in 2013.

The authors used quality measures that changed over time and weren’t valid across the entire decade of their study, which means the measures didn’t necessarily reflect the current best clinical practice. Also, 46 indicators is a relatively small number by which to assess quality of care, and they were chosen because they could be scored using administrative data rather than because of their importance.

Elizabeth A. McGlynn, PhD, is at Kaiser Permanente Research, Pasadena, Calif. She and her associates reported having no relevant financial disclosures. They made these remarks in an invited commentary accompanying Dr. Levine’s report (JAMA Intern Med. 2016 Oct 17. doi: 10.1001/jamainternmed.2016.6233).

Key clinical point: The clinical quality of outpatient care for adults in the United States did not improve consistently from 2002 to 2013.

Major finding: Approximately half of elderly adults underwent inappropriate cancer screening when it was unlikely to prolong life, approximately half of adults who saw a clinician for a viral illness received inappropriate antibiotics, and approximately 15% who consulted a clinician for back pain received an inappropriate lumbar radiograph.

Data source: An analysis of 10-year trends in quality of care based on data from nationally representative annual surveys of 20,679 to 26,509 adult outpatients.

Disclosures: This study was supported in part by the National Institutes of Health and the Ryoichi Sasakawa Fellowship Fund. Dr. Levine and his associates reported having no relevant financial disclosures.

Crusted Plaque in the Umbilicus

The Diagnosis: Sister Mary Joseph Nodule

The umbilical skin biopsy revealed a moderately differentiated adenocarcinoma (Figure) that was positive for cytokeratin 20 and CDX2 and negative for cytokeratin 7 and transcription termination factor 1. The patient subsequently underwent computed tomography of the abdomen and pelvis, which showed multiple soft-tissue nodules on the greater omentum, a soft-tissue density at the umbilicus, and thickening of the gastric mucosa. An upper endoscopy was then performed, which revealed a large fungating ulcerated mass in the stomach. Biopsy of this mass showed an invasive moderately differentiated adenocarcinoma, which was ERBB2 (formerly HER2) negative. Histopathologically, these pleomorphic glands looked similar to the glands seen in the original skin biopsy. With this diagnosis of metastatic gastric adenocarcinoma, our patient chose palliative chemotherapy but declined precipitously and died 2 months after the initial skin biopsy of the umbilical lesion.

When encountering a patient with an umbilical lesion, it is important to consider benign and malignant lesions in the differential diagnosis. A benign lesion may include scar, cyst, pyogenic granuloma, hemangioma, umbilical hernia, endometriosis, polyp, abscess, or the presence of an omphalith.1 Inflammatory dermatoses such as psoriasis or eczema also should be considered. Malignant lesions could be either primary or secondary, with metastatic disease being the most common.2 Sister Mary Joseph nodule (SMJN) is the eponymgiven to an umbilical lesion representing metastatic disease. Sister Mary Joseph was a nurse and surgical assistant to Dr. William Mayo in Rochester, Minnesota, in what is now known as the Mayo Clinic. She is credited to be the first to observe and note the association between an umbilical nodule and intra-abdominal malignancy. Metastasis to the umbilicus is thought to occur by way of contiguous, hematogenous, lymphatic, or direct spread through embryologic remnants from primary cancers of nearby gastrointestinal or pelvic viscera. It is a rare cutaneous sign of internal malignancy, with an estimated prevalence of 1% to 3%.3 The most common primary cancer is gastric adenocarcinoma, though cases of metastasis from pancreatic, endometrial, and less commonly hematopoietic or supradiaphragmatic cancers have been reported.4 It is more common in women, likely due to the addition of gynecologic malignancies.1

 

 

The use of dermoscopy has been advocated as an adjuvant tool in delineating benign and malignant umbilical lesions when an atypical polymorphous vascular pattern indicating neovascularization has been observed with neoplastic growth.5 Once a suspicious umbilical lesion is identified, the first step should be to obtain a skin biopsy or to use fine needle aspiration for cytology.6 Biopsy is especially relevant in the background of cancer history because SMJN may present with cancer recurrence.3 Once one of these is obtained, histological and immunohistochemical analysis will guide further workup and diagnosis of the umbilical lesion.

The importance of reviewing such cases lies in the variable presentation of cutaneous metastases such as SMJN and the grim prognosis that accompanies this finding. It presents as a firm indurated plaque or nodule that may present with systemic symptoms suggestive of malignancy, though in 30% of cases it is the sole initial sign.7 The nodule may be painful if ulcerated or fissured. Bloody, serous, or purulent discharge may be present. After diagnosis of an SMJN, most patients succumb to the disease within 12 months. Thus, it is vital for dermatologists to investigate umbilical lesions with great caution and a high index of suspicion.

Questionnaire Body

A 74-year-old man presented to our outpatient dermatology clinic with an asymptomatic umbilical lesion of unknown duration. The patient believed the lesion was a scar resulting from a prior laparoscopic repair of an umbilical hernia. However, the patient reported epigastric abdominal pain and diarrhea of 1 month's duration that he believed was due to the stomach flu. The patient denied fever, chills, loss of appetite, or weight loss. History was remarkable for hypertension, hyperlipidemia, coronary artery disease, chronic kidney disease, and emphysema. The patient had a surgical history of percutaneous transluminal coronary angioplasty in addition to the laparoscopic umbilical hernia repair. The patient's medications included pantoprazole, ondansetron, diphenoxylate-atropine as needed, amlodipine, lisinopril-hydrochlorothiazide, simvastatin, and aspirin. Physical examination revealed a 1×2-cm pink, nodular, firm plaque with crust at the umbilicus that was tender on palpation. A shave biopsy of the umbilicus was performed and sent for both pathological and immunohistochemical analysis.

Postinflammatory erythema

Article Type
Changed

 

The troubling, frustrating part of acne: the persistent acne scars that are often a prolonged battle for most of our patients. We have many techniques to deal with postinflammatory hyperpigmentation (PIH). However, postinflammatory erythema (PIE), the erythematous scars often seen in acne and other inflammatory skin conditions, is not well understood. And despite its pervasive nature, very little data exist that identify its etiology and effective treatment options.

Inflammatory acne scars are not all the same. PIH, often seen with Fitzpatrick skin types III-VI, is related to brown spots, not red spots. Hyperpigmentation is caused by an excess production of melanin. There are treatments for PIH in our armamentarium – such as microdermabrasion, chemical peels, hydroquinone, and vitamin C – that inhibit melanogenesis and blend the skin discoloration.

Dr. Lily Talakoub


In contrast, PIE is characterized by pink, red, and sometimes purple-appearing vascular neogenesis seen most often with skin types I-III after an inflammatory skin condition resolves, and is often seen in cystic acne.

The term postinflammatory erythema was initially introduced in the dermatology literature in 2013 by Bae-Harboe et al. to describe erythema often seen after the resolution of inflammatory acne or other inflammatory skin conditions.1 It is not to be confused with the erythema and telangiectasias seen in erythematotelangiectatic rosacea, which is a separate entity.

Dr. Naissan O. Wesley
Anecdotal studies have shown that pulsed dye and Nd:YAG lasers, which target hemoglobin through the process of selective photothermolysis, are effective at decreasing the vascular prominence in PIE. In clinical practice, a combination of pulsed dye lasers, KTP laser, intense pulsed-light, and Nd:YAG lasers has been effective in reducing both the superficial and deep vascular prominence seen with PIE.2

In my practice, microneedling has also been effective in reducing PIE. Although this may seem counterintuitive because of the bleeding associated with the microneedling process, microneedling-induced skin tissue injury and neocollagenesis have been clinically shown to improve the abnormal vascular proliferation that occurs in PIE. Similar techniques can be used with fractional resurfacing lasers. However, no studies have specifically evaluated the erythematous component of acne scars treated with fractionated lasers.

Topical preparations containing brimonidine (Mirvaso), azelaic acid, and green tea, as well as oral nicotinamide, can have a temporary effect on reducing skin erythema.

However, very little data or clinical studies are available on treatments for PIE, and there are no well-studied preparations with long-term efficacy data. Studies are needed to provide better clinical guidelines for treatment methods and alternatives to treatments, including topical and systemic medications.

Delayed ICU Transfer Affects Mortality and Length of Stay

Delayed ICU Transfer Affects Mortality and Length of Stay

Clinical Question: Can an objective measurement of critical illness inform intensive care unit (ICU) transfer timeliness?

Background: Early intervention has shown mortality benefit in many critical illness syndromes, yet heterogeneity in timing of ICU transfer exists. Previous studies examining ICU transfer timeliness have mostly focused on subjective criteria.

Study Design: Retrospective observational cohort study.

Setting: Medical-surgical units at five hospitals including the University of Chicago and NorthShore University HealthSystem in Illinois.

Synopsis: All medical-surgical ward patients between November 2008 and January 2013 were scored using eCART, a previously validated objective scoring system, to decide when transfer was appropriate. Of those, 3,789 patients reached the predetermined threshold for critical illness. Transfers more than six hours after crossing the threshold were considered delayed. Patients with delayed transfer had a statistically significant increase in length of stay (LOS) and in-hospital mortality (33.2% versus 24.5%; P < 0.001), and the mortality increase was linear, with a 3% increase in odds for each one hour of further transfer delay (P < 0.001). The rate of change of eCART score did influence time of transfer, and the authors suggest that rapid changes were more likely to be recognized. They postulate that routine implementation of eCART or similar objective scoring may lead to earlier recognition of necessary ICU transfer and thus improve mortality and LOS, and they suggest this as a topic for future trials.

Bottom Line: Delayed ICU transfer negatively affects LOS and in-hospital mortality. Objective criteria may identify more appropriate timing of transfer. Clinical trials to investigate this are warranted.

They postulate that routine implementation of eCART or similar objective scoring may lead to earlier recognition of necessary ICU transfer and thus improve mortality and LOS, and they suggest this as a topic for future trials.

Bottom Line: Delayed ICU transfer negatively affects LOS and in-hospital mortality. Objective criteria may identify more appropriate timing of transfer. Clinical trials to investigate this are warranted.

Short Take

Intranasal Live Attenuated Influenza Vaccine Not Recommended

The Centers for Disease Control and Prevention recommends against use of the nasal spray live attenuated influenza vaccine. This is based on data showing poor effectiveness in prior years.

IV Fluid Can Save Lives in Hemodynamically Stable Patients with Sepsis

Clinical Question: Does increased fluid administration in patients with sepsis with intermediate lactate levels improve outcomes?

Background: The Surviving Sepsis Campaign bundle, which improves ED mortality, targets patients with hypotension or lactate levels >4 mmol/L. No similar optimal treatment strategy exists for less severe sepsis patients even though such patients are more common in hospitalized populations.

Study Design: Retrospective study of a quality improvement bundle.

Setting: 21 community-based hospitals in the Kaiser Permanente Northern California system.

Synopsis: This study evaluated implementation of a treatment bundle for 18,122 hemodynamically stable sepsis patients presenting to the ED with lactate levels between 2 and 4 mmol/L during the 12 months prior to and after bundle implementation. The bundle included antibiotic administration within three hours, repeated lactate levels within four hours, and 30 mL/kg or ≥2 L of intravenous fluids within three hours of initial lactate result. Patients with kidney disease and/or heart failure were separately evaluated because of the perceived risk of fluid administration.

Treatment after bundle implementation was associated with an adjusted hospital mortality odds ratio of 0.81 (95% CI, 0.66–0.99; P = 0.04). Significant reductions in hospital mortality were observed in patients with heart failure and/or kidney disease (P < 0.01) but not without (P > 0.4). This correlated with increased fluid administration in patients with heart failure and/or kidney disease following bundle implementation. This is not a randomized controlled study, which invites biases and confounding.

Bottom Line: Increased fluid administration improved mortality in patients with kidney disease and heart failure presenting with sepsis.

New Framework for Learners’ Clinical Reasoning

A qualitative study involving 37 emergency medicine residents found that clinical reasoning through individual cases progresses from case framing (phase 1) to pattern recognition (phase 2), then self-monitoring (phase 3).
