BACKGROUND: Across cancers, the decision to pursue genetic testing is influenced more by subjective than objective factors. However, skin cancer, which is more prevalent, visual, and multifactorial than many other malignancies, may offer different motivations for pursuing such testing. OBJECTIVES: The primary objective was to determine factors influencing the decision to receive genetic testing for skin cancer risk. A secondary objective was to assess the impact of priming with health questions on the decision to receive testing...

BACKGROUND: Biologics seem to offer a promising nonsurgical approach in hidradenitis suppurativa (HS), especially in disease with highly pronounced inflammation. Recent studies revealed increased expression of a broad range of cytokines in lesional HS skin, including interleukin (IL)-17. OBJECTIVE: This study was undertaken to determine IL-17 serum levels in this group of patients. METHODS: Our study was conducted on a group of 86 patients between 16 and 72 years of age with HS...

REVIEW
Powell Perng, John G Zampella, Ginette A Okoye
Hidradenitis suppurativa is a debilitating inflammatory skin disease with a chronic course and often disappointing response to treatment. Though a minority of persons (20%) reports symptom remission during pregnancy, the vast majority experiences no relief (72%), and few experience clinical deterioration (8%). Disease flares are also observed post-partum. The pathophysiological basis for pregnancy-associated fluctuations in clinical status is currently unknown. Because most women with HS require ongoing management throughout pregnancy, it is important to evaluate the suitability and safety of current treatment options for pregnant women...

REVIEW
Isabella Jascholt, Olivia Lai, Detlef Zillikens, Michael Kasperkiewicz
Periodontitis and autoimmune bullous diseases, including pemphigus vulgaris and mucous membrane pemphigoid, are immunoinflammatory disorders leading to microbial plaque- and autoantibody-elicited tissue injury of the oral cavity, respectively. Evidence indicates that these autoimmune conditions may represent a risk factor for periodontitis, but no systematic evaluation exists to corroborate this assumption. A systematic literature review of periodontal status in pemphigus and pemphigoid was conducted. Electronic searches using PubMed from inception to July 2016 identified 10 studies meeting predetermined inclusion and exclusion criteria...

BACKGROUND: Drug survival is defined as the time period of treatment with a certain drug until its cessation. The role of previous exposure to traditional systemic treatments in biologic survival is still unknown. OBJECTIVE: To investigate the drug survival rates of biologic treatments in patients with psoriasis and to identify predictor factors. METHODS: Survival analysis was performed on patients with severe psoriasis who received adalimumab, infliximab, etanercept, and ustekinumab for treatment of psoriasis, drawn from the Clalit Health Services database...

BACKGROUND: Serologic diagnosis of autoimmune blistering disease (AIBD) usually follows a sophisticated multistep algorithm. OBJECTIVE: We sought validation of a multivariant enzyme-linked immunosorbent assay (ELISA) in the routine diagnosis of AIBD. METHODS: The multivariant ELISA comprising 6 recombinant immunodominant forms of major AIBD target antigens, ie, desmoglein 1, desmoglein 3, envoplakin, BP180, BP230, and type VII collagen was applied in: (1) a cohort of well-characterized AIBD (n = 173) and control sera (n = 130), (2) a prospective multicenter study with 204 sera from patients with newly diagnosed AIBD with positive direct immunofluorescence microscopy, and (3) a prospective monocenter study with 292 consecutive sera from patients with clinical suspicion of AIBD in comparison with the conventional multistep diagnostic algorithm...

BACKGROUND: The Pigmented Lesion Subcommittee of the Melanoma Prevention Working Group recently published a consensus statement that incompletely excised moderately dysplastic nevi (MDN) without clinical residual pigmentation can be observed and not re-excised. However, data regarding recurrence of MDN with positive histologic margins are quite scant. OBJECTIVE: We sought to extend the reported findings with a study to determine the recurrence rate of MDN with positive histologic margins...

BACKGROUND: Inflammatory bowel disease (IBD) occurs more frequently in patients with psoriasis. The 2 diseases have significant genetic overlap, but the pathogenesis underlying their co-occurrence is unknown. OBJECTIVE: We sought to report adjudicated IBD cases (Crohn's disease [CD] and ulcerative colitis [UC]) in patients exposed to ixekizumab, a high-affinity monoclonal antibody that selectively targets interleukin-17A. METHODS: Adverse events (AEs) integrated from 7 randomized controlled and uncontrolled trials were analyzed for the controlled induction period, controlled maintenance period, and all ixekizumab-treated patients...

Electromagnetic radiation in the ultraviolet, visible, and infrared ranges all produce biologic effects. Ultraviolet filters are the most well-studied photoprotective measure for the adverse effects of ultraviolet radiation. Because of the reported endocrinologic effects of oxybenzone in animal studies, its effects on coral reefs, and its photocontact allergy potential, its use has been minimized in many countries worldwide. New developments in topical antioxidants and oral and subcutaneous agents (eg, Polypodium leucotomos extract, afamelanotide, nicotinamide) with photoprotective and antiphotocarcinogenic properties could potentially provide addition modalities for protection against the effects of visible light and infrared radiation...

The efficacy of sunscreens can be measured by different methods, involving in vitro, ex vivo, or in vivo techniques. There is a need for a worldwide standardization of these methods to avoid misunderstanding and confusion among sunscreen users. The clinical benefits of sunscreens have been demonstrated in randomized controlled trials that established the role of sunscreens in the prevention of actinic keratoses, squamous cell carcinomas, nevi, and melanomas. Sunscreens also prevent photoimmunosuppression and signs of photoaging...
