Geomapping of pediatric dermatologists: A tool to promote diversity and equity in dermatology.

There is a lack of racial and ethnic diversity across the field of dermatology, including the subspecialty of pediatric dermatology. Residency programs are improving recruitment and mentorship of medical students who identify with racial or ethnic minority communities (underrepresented in medicine [URiM]) to dermatology overall, a goal similarly held by our subspecialty. The objectives of this study were to create an online mapping tool to visually centralize the list of 142 dermatology residency programs, 105 with practicing pediatric dermatologists on faculty and 51 that offer financial scholarships for URiM visiting medical students completing away rotations.

Risk Factors Predicting Cellulitis Diagnosis in a Prospective Cohort Undergoing Dermatology Consultation in the Emergency Department.

Cellulitis is an infection of the skin and skin-associated structures with many clinical mimickers known collectively as pseudocellulitis. Dermatology or infectious disease consultation is considered the gold standard for diagnosis. We evaluated a prospective cohort of adult patients presenting to the emergency department (ED) with concern for lower extremity cellulitis who received dermatology consultation with conferral of a final diagnosis.

Improved erythema and decreased blister formation in dominant dystrophic epidermolysis bullosa following treatment with pulsed dye laser.

Dominant dystrophic epidermolysis bullosa (DDEB), an inherited disorder due to type VII collagen mutations, is characterized by blisters and erosions that heal with scarring, atrophy, and milia. There is no established role for laser in the management of patients with DDEB. Pulsed dye laser (PDL) is most often used to target vascular skin lesions.

Diffuse Reflectance Spectroscopy with Infrared Thermography for Accurate Prediction of Cellulitis.

Cellulitis is frequently misdiagnosed owing to its clinical mimickers, collectively known as pseudocellulitis. This study investigated diffuse reflectance spectroscopy (DRS) alone and in combination with infrared thermography (IRT) for the differentiation of cellulitis from pseudocellulitis. A prospective cohort study at an urban academic hospital was conducted from March 2017 to March 2018.

Clinical mimickers of calciphylaxis: A retrospective study.

Background: Calciphylaxis is an ischemic vasculopathy with high morbidity and mortality. Early and accurate diagnosis is critical to management of calciphylaxis. Clinical mimickers may contribute to delayed or misdiagnosis.

Classification of lower extremity venous malformations and risk of knee involvement: A retrospective cohort study.

Background: Venous malformation (VM) is the most common vascular anomaly in the lower extremity. VMs can be classified as focal, multifocal, or diffuse types. Intraarticular VM (IA-VM) of the knee portends morbidity.

Pediatric allergic contact dermatitis. Part 2: Patch testing series, procedure, and unique scenarios.

Patch testing is the criterion standard for diagnosing allergic contact dermatitis. Causative allergens differ between children and adults, necessitating the development of pediatric-specific patch test series. The Pediatric Baseline Series was developed in 2018 through expert consensus and includes relevant pediatric allergens that dermatologists can use in practice.

Pediatric allergic contact dermatitis. Part I: Clinical features and common contact allergens in children.

Allergic contact dermatitis (ACD), a delayed hypersensitivity skin reaction to environmental allergens, has a prevalence that is similar in children and adults. However, diagnostic testing for ACD in pediatric populations accounts for less than one tenth of all patch tests. The relative infrequency of pediatric patch testing may be attributed to the difficulty in testing in this population, which includes a smaller surface area for patch test placement and maintaining cooperation during patch testing, especially in younger children.

Assessment of outcomes of calciphylaxis.

Background: Calciphylaxis is a rare thrombotic vasculopathy characterized by high morbidity and mortality. There is a paucity of studies examining longitudinal outcomes.

Objective: To assess mortality, days spent in the hospital, and amputations in patients with calciphylaxis.

Penile calciphylaxis: A retrospective case-control study.

Background: Calciphylaxis is a rare disorder characterized by skin necrosis caused by calcium deposition within vessels, thrombosis, and subsequent tissue ischemia. Penile involvement may rarely occur.

Objective: To identify risk factors, diagnosis, management, and mortality of patients with penile calciphylaxis.

The Successful Use of Apixaban in Dialysis Patients with Calciphylaxis Who Require Anticoagulation: A Retrospective Analysis.

Calciphylaxis is a disease of dermal arteriolar calcification that results in necrosis. It commonly occurs in individuals with end-stage renal disease (ESRD) on hemodialysis and is associated with a high morbidity and mortality. Warfarin use is an identified risk factor.

Clinical Usefulness of Imaging and Blood Cultures in Cellulitis Evaluation.

This cohort study examines the clinical usefulness and cost of blood cultures and imaging in patients with presumed cellulitis.

Identification of interactions among host and bacterial proteins and evaluation of their role early during Shigella flexneri infection.

Shigella species cause diarrhoea by invading and spreading through the epithelial layer of the human colon. The infection triggers innate immune responses in the host that the bacterium combats by translocating into the host cell cytosol via a type 3 secretion system bacterial effector proteins that interfere with host processes. We previously demonstrated that interaction of the Shigella type 3 secreted effector protein IcsB with the host protein Toca-1 inhibits the innate immune response microtubule-associated protein light-chain 3 (LC3)-associated phagocytosis, and that IcsB interaction with Toca-1 is required for inhibition of this host response.

Effect of Dermatology Consultation on Outcomes for Patients With Presumed Cellulitis: A Randomized Clinical Trial.

Importance: Each year, cellulitis leads to 650 000 hospital admissions and is estimated to cost $3.7 billion in the United States. Previous literature has demonstrated a high misdiagnosis rate for cellulitis, which results in unnecessary antibiotic use and health care cost.
