A bulky dressing is applied following nail biopsy, and patients are instructed to keep it dry for 48 hours; however, this can be challenging, as the dressing can restrict bathing, washing dishes, and other daily tasks. We propose a solution using a removable waterproof arm cast protector that allows patients to continue their regular activities while keeping the dressing dry and intact to allow for optimal wound healing.

Acne keloidalis nuchae (AKN) is a chronic inflammatory condition of the hair follicles that manifests as papules, pustules, and keloid-like plaques on the occipital scalp. In this retrospective study, we evaluated the most commonly used treatments and their efficacy in a large population of patients with AKN. We performed a cross-sectional analysis of patient medical records from the Los Angeles County hospital system in California over a period of 6 years. A total of 101 patients were included based on diagnosis of AKN by a dermatologist and documented treatment outcomes. Clindamycin and clobetasol were the most commonly prescribed topical treatments, while doxycycline was the most commonly prescribed systemic medication; intralesional (IL) triamcinolone also was commonly used. Most patients responded positively to these treatment regimens, but very few had full resolution with these treatments, reflecting a need for further study and new therapeutic modalities for AKN.

Patch testing (PT) is the gold standard diagnostic test for allergic contact dermatitis (ACD) and is essential for guiding allergen avoidance. Comprehensive PT refers to the completion of PT for all potentially relevant and testable allergens for a given patient. It is necessary for most patients with contact allergy and can illustrate allergen trends and identify allergens that otherwise would be missed using a limited screening panel. Early identification of relevant allergens leads to clinical improvement, improved quality-of-life, and reduced health care utilization. This article illustrates the clinical and public health value of comprehensive PT and the vital role of allergen access in the comprehensive patch test process.

Rosacea is a chronic inflammatory skin condition characterized by facial erythema, flushing, telangiectasias, papules, and pustules. Its pathophysiology involves a multifactorial interplay of genetic, immune, microbial, and neurovascular factors contributing to inflammation and vascular dysregulation. Environmental and lifestyle triggers are important contributors to disease exacerbation. In this review, we highlight 4 major modifiable triggers-UV radiation exposure, temperature fluctuation, skin care practices, and diet-and their roles in rosacea pathogenesis and management. Lifestyle modifications targeting these triggers combined with topical, oral, and/or laser therapies can improve disease control. A holistic, patient-specific approach to treatment that involves education on environmental influences and tailored management strategies is essential.
