Skin Tone Representation in Dermatologist Social Media Accounts.

Objective: Skin conditions manifest differently on darker skin tones, yet lighter skin tones are usually overrepresented in dermatology educational resources. Our aim was to explore the representation of skin tones within dermatology social media posts in 2019.

Methods: This is a retrospective review of posts made on Instagram, YouTube, and Twitter by the top 2019 dermatology social media influencers.

The evaluation and management of macronutrient deficiency dermatoses.

In industrialized countries, nutritional dermatoses are likely underdiagnosed and result in increased disease morbidity and utilization of hospital resources. These findings underscore the need for physicians to be able to correctly identify these deficiencies. Nutritional dermatoses may be split into micronutrient deficiencies and macronutrient deficiencies.

The epidemiology, impact, and diagnosis of micronutrient nutritional dermatoses. Part 2: B-complex vitamins.

Nutritional dermatoses are traditionally taught in the context of developing countries, famine, population displacement, and limited access to health care. In the United States, nutritional dermatoses may be underdiagnosed, leading to increased morbidity and utilization of hospital resources. These findings underscore the need for providers in developed nations to be able to identify these deficiencies.

Evaluation of a Case Series of Patients With Palmoplantar Pustulosis in the United States.

Importance: Palmoplantar pustulosis (PPP) is a is a chronic, orphan disease with limited epidemiological data.

Objective: To describe the clinical characteristics, treatments, longitudinal disease course, and health care utilization in adults with PPP across the US.

Design, Setting, And Participants: This retrospective, longitudinal case series from 20 academic dermatology practices in the US included a consecutive sample of 197 adults who met the European Rare and Severe Psoriasis Expert Network consensus definition for PPP between January 1, 2007, and December 31, 2018.

Evaluation of a Case Series of Patients With Generalized Pustular Psoriasis in the United States.

Importance: Generalized pustular psoriasis (GPP) is a chronic, orphan disease with limited epidemiological data.

Objective: To describe the clinical characteristics, treatments, longitudinal disease course, and disease-specific health care utilization among patients with GPP across the United States.

Design, Setting, And Participants: A retrospective longitudinal case series involving 95 adults who met the European Rare and Severe Psoriasis Expert Network consensus definition for GPP and were treated at 20 US academic dermatology practices between January 1, 2007, and December 31, 2018.

The epidemiology, impact, and diagnosis of micronutrient nutritional dermatoses part 1: Zinc, selenium, copper, vitamin A, and vitamin C.

Dermatologists play a critical role in diagnosing and managing nutritional deficiencies as they often present with cutaneous findings. Traditionally, nutritional dermatoses are taught in the context of developing countries, famine, population displacement, and poor health care access; however, in the United States, common risk factors include chronic liver disease, alcoholism, psychiatric disease, bariatric surgery, inflammatory bowel disease, and hemodialysis. Additionally, nutritional dermatoses may be underdiagnosed in the United States and result in increased morbidity and utilization of hospital resources.

In vitro diagnostics for the medical dermatologist. Part II: Hypercoagulability tests.

The skin often provides initial clues of hypercoagulability with features such as livedo reticularis, livedo racemosa, retiform purpura, necrosis, and ulcerations. Because these cutaneous manifestations are nonspecific, laboratory testing is often needed to evaluate for underlying causes of hypercoagulability. Importantly, these disorders are reported to be the most common mimicker, resulting in an erroneous diagnosis of pyoderma gangrenosum.

Erosive pustular dermatosis of the scalp.

Erosive pustular dermatosis of the scalp (EPDS) is a rare inflammatory condition commonly associated with antecedent iatrogenic insult. EPDS may be diagnostically challenging owing to a lack of pathognomonic histologic findings and cutaneous manifestations that overlap with alternative dermatologic conditions. Therefore, EPDS may be more common than previously recognized.

A Retrospective Review of New-onset Dermatitis in Patients Aged 60 Years or Older.

New-onset dermatitis in the elderly can be attributed to a variety of disease processes. We defined new-onset dermatitis in which the etiology is attributed solely to age-related processes as "dermatitis of immune senescence"-a diagnosis of exclusion based on clinical presentation and further diagnostic testing. Retrospective cohort of elderly patients with new-onset dermatitis to examine the differences in demographics, work-up, and treatments between patients with dermatitis of immune senescence and those patients ultimately given more specific diagnoses.

Erythema multiforme as a reaction to imiquimod 5% cream.

We describe a patient with erythema multiformefollowing a local site reaction after the use of topicalimiquimod 5% cream and review the literature forprevious reports of this cutaneous adverse effect.

A Retrospective Analysis Comparing the New Standardized Letter of Recommendation in Dermatology with the Classic Narrative Letter of Recommendation.

In an effort to avoid numerous problems associated with narrative letters of recommendation, a dermatology standardized letter of recommendation was utilized in the 2014-2015 resident application cycle. A comparison of the standardized letter of recommendation and narrative letters of recommendation from a single institution and application cycle to determine if the standardized letter of recommendation met its original goals of efficiency, applicant stratification, and validity. Eight dermatologists assessed all standardized letters of recommendation/narrative letters of recommendation pairs received during the 2014-2015 application cycle.

Magnetic resonance elastography and transient elastography as non-invasive analyses for liver fibrosis: can they obviate the need for liver biopsy in psoriasis patients treated with methotrexate?

The liver biopsy has been regarded as the reference standard method of monitoring hepatic fibrosis in psoriasis patients treated with methotrexate. It has also been subject to concerns over sampling error, internal and external variability, and potential for morbidity and mortality. During the past two decades, two imaging techniques, magnetic resonance elastography and transient elastography, have been developed and approved by the US Food and Drug Administration (FDA) for the assessment of hepatic fibrosis.
