The objectives are to determine the frequency that skin color is reported in randomized controlled trials (RCTs) involving squamous cell carcinoma (SCC) detection and treatment in leading dermatology journals. A systematic review of RCTs involving SCC was conducted among the top ten most impactful dermatology journals from inception to July 10th, 2023. Studies were included if they reviewed the treatment, prevention, or detection of SCC, involved patients directly and were classified as traditional RCTs. Studies were considered positive for reporting SOC if there was any demographic data in the methods or results of the following terms: Fitzpatrick scale, race, ethnicity, sunburn tendency, or skin of color...

BACKGROUND: Millions of people worldwide are affected by psoriasis, one of the most prevalent skin conditions. Currently, there is a lack of high-quality epidemiological reports on psoriasis. OBJECTIVE: This study aimed to reveal trends in psoriasis epidemiology in 1990-2019. METHODS: Using data from the GBD study 2019, we examined psoriasis epidemiology globally and across regions defined by the social-demographic index (SDI). Trends in incidence, prevalence, and disability-adjusted life year (DALY) rates were assessed using estimated annual percentage changes (EAPC)s...

The Investigator Global Assessment of Chronic Hand Eczema (IGA-CHE) is a novel Clinician-Reported Outcome measure that allows investigators to assess cross-sectional CHE global disease severity using clinical characteristics of erythema, scaling, lichenification/hyperkeratosis, vesiculation, oedema, and fissures as guidelines for overall severity assessment. This study aimed to evaluate the psychometric properties of the IGA-CHE for use as an outcome measure in CHE clinical trials and clinical practice. Psychometric analyses were performed using data from a sample of 280 patients with moderate to severe CHE from a phase 3 trial of delgocitinib cream, pooled across treatment groups...

Cutaneous field cancerization in dermatology describes the anatomic region of photodamaged skin with actinic keratoses (AKs) or cutaneous squamous cell carcinoma (cSCC) that is surrounded by cellular atypia, forming a dysplastic field. The concept of field cancerization is especially relevant in dermatology, as actinic keratoses and the surrounding dysplastic region can progress to carcinomas, necessitating the treatment of the field. Recent research has focused on field-directed therapy using topical agents...

The relationship between acne vulgaris and oxidative stress biomarkers lacks a clear consensus. This study aimed to explore the potential correlation between acne vulgaris and circulating oxidative stress biomarkers (superoxide dismutase [SOD], malondialdehyde [MDA], and total antioxidant capacity [TAC]). We searched the PubMed, Embase, and Cochrane Library databases for articles published before June 26, 2023. The literature search combined free words and the medical subject headings terms related to acne vulgaris, SOD, MDA, and TAC...

No randomized trials exist to inform the peripheral surgical margins or depth of wide excision for eyelid melanoma. We performed a meta-analysis examining surgical margins and Breslow depth for eyelid melanomas. A systematic review was performed in August 2022 using PubMed, Cochrane, and Medline databases (1/1/1990 to 8/1/2022). Inclusion criteria included studies reporting surgical treatment of primary cutaneous melanomas of the eyelid with reported surgical margins. Ten articles were included. The studies were examined by surgical margin size (group 1: ≤ 0...

Herpes (varicella) zoster (HZ) infection occurs in 4 people per 1000 in the general US population (irrespective of prior varicella infection and vaccination status) each year and has been the subject of scientific inquiry for decades. The consequences of infection are myriad and may depend on the dermatome of involvement as well as host factors such as age, comorbidities, prior treatment or immunization, and immunologic status. Pregnancy is associated with an altered immune and hormonal status in the mother...

Topical corticosteroids, topical steroid-sparing agents, and emollients are all used to treat atopic dermatitis. However, there are no formal guidelines dictating the order and timing in which these topical modalities should be applied. Additionally, the order of application may change drug absorption, efficacy, and distribution. This is especially important for patients with atopic dermatitis. These patients have a dysfunctional skin barrier, which can lead to greater systemic absorption of drugs. Moreover, children already have an increased rate of systemic absorption due to a higher ratio of body surface area to body weight...

While time spent practicing inpatient dermatology has decreased since the 1990s, less is known about the current state of inpatient dermatology. We describe the distribution and frequency of inpatient dermatology encounters servicing the United States Medicare population between 2013 and 2019. Cross-sectional analysis of publicly available inpatient Medicare Part B claims data from 2013 to 2019 was conducted. Main outcomes and measures were characteristics and trends of dermatologists performing inpatient encounters...

Atopic dermatitis (AD) stands as a prevalent chronic inflammatory skin disorder with a global reach. Beyond its cutaneous manifestations, AD is accompanied by comorbidities and psychological issues, significantly compromising the overall quality of life for individuals who suffer from AD. Previous research has evidenced a heightened prevalence of addictive disorders among dermatological patients when compared to the general population. Considering these findings, this study endeavors to examine the prevalence of addictive disorders among AD patients and, furthermore, to discern potential risk factors associated with this comorbidity...

Seborrheic dermatitis (SD) is an inflammatory skin disorder and eczema subtype increasingly recognized to be associated with significant physical, psychosocial, and financial burden. The full spectrum of SD, including dandruff localized to the scalp, is estimated to affect half of the world's population. Despite such high prevalence, the exact etiopathogenesis of SD remains unclear. Historically, many researchers have theorized a central, causative role of Malassezia spp. based on prior studies including the proliferation of Malassezia yeast on lesional skin of some SD patients and empiric clinical response to antifungal therapy...

This paper presents the most current and innovative solutions applying modern digital image processing methods for the purpose of skin cancer diagnostics. Skin cancer is one of the most common types of cancers. It is said that in the USA only, one in five people will develop skin cancer and this trend is constantly increasing. Implementation of new, non-invasive methods plays a crucial role in both identification and prevention of skin cancer occurrence. Early diagnosis and treatment are needed in order to decrease the number of deaths due to this disease...

Peristomal pyoderma gangrenosum is an uncommon subtype of pyoderma gangrenosum mainly affecting stoma sites of patients with inflammatory bowel disease. While surgical treatments are often used to assist healing, little is known about the relationship between surgical interventions and the rate of recurrence of peristomal pyoderma gangrenosum. The aim of this study was to identify patient and clinical factors associated with peristomal pyoderma gangrenosum recurrence following surgical intervention. A multi-institutional retrospective case series and literature review was conducted to evaluate patient characteristics and perioperative treatment...

Programmed cell death protein-1 (PD-1) is an immune checkpoint protein, PD-1 interaction with PD ligand-1 (PD-L1) is essential for maintaining immunological tolerance. The study aimed to study and compare the levels of PD-1 and PD-L1 in lesional and nonlesional skin of lichen planus (LP) patients and compare these levels to normal healthy controls to assess their role in the pathogenesis of LP. This case-control study involved 30 patients with LP and 30 healthy age-and sex-matched controls. After clinical assessment of the severity by LP severity index score (LPSI), skin biopsies were taken from lesional and nonlesional skin of LP patients and from normal skin in healthy controls for assessment of the tissue levels of PD-1 and PD-L1 by ELISA...

Given the higher susceptibility to infectious disease in patients receiving immunosuppressive therapies for inflammatory dermatologic conditions, immunization is important in this population. While live vaccines protect against life-threatening diseases, they can be harmful in immunosuppressed patients given the risk of replication of the attenuated pathogen and adverse reactions. The utilization of live vaccines in immunosuppressed patients depends on multiple factors such as the vaccine and therapy regimen...
