Nailfold microscopy in adult-onset dermatomyositis in association with myositis antibodies.

Dermatomyositis (DM) is an immune mediated inflammatory disease classically associated with muscular and cutaneous involvement. Existing studies have suggested characteristic nailfold findings may be observed in DM, indicating a potential role for nailfold microscopic examination in the diagnosis of DM. To that end, we performed a systematic review of literature pertaining to nailfold microscopic, capillaroscopic, and dermoscopic findings observed in patients with DM, with a secondary review of the association of nailfold microscopic findings with myositis-specific antibody (MSA) and myositis-associated antibody (MAA) status.

Treatment of mild to severe acne with 1726 nm laser: A safe alternative to traditional acne therapies.

Introduction: Acne is the most common reason for dermatology consultation in adolescents and young adults. Consultation is often delayed despite unsuccessful self-treatment. Postponing effective treatment places acne sufferers at higher risk for permanent acne scars and post-inflammatory pigment changes.

Pseudocarcinomatous hyperplasia in anaplastic large cell lymphoma, a mimicker of poorly differentiated squamous cell carcinoma: report of a case and review of the literature.

Pseudocarcinomatous hyperplasia can occasionally be observed in biopsies of CD30-positive lymphoproliferative disorders. It is important to be cognizant of this association, because epithelial hyperproliferation can overshadow large atypical lymphoid cells, leading to an erroneous diagnosis of squamous cell carcinoma (SCC) or keratoacanthoma. Herein, we present a case of anaplastic large cell lymphoma (ALCL) with pseudocarcinomatous hyperplasia simulating a poorly differentiated carcinoma and review the literature on this subject.

Insect repellents: historical perspectives and new developments.

Arthropod bites remain a major cause of patient morbidity. These bites can cause local or systemic effects that may be infectious or inflammatory in nature. Arthropods, notably insects and arachnids, are vectors of potentially serious ailments including malaria, West Nile virus, dengue, and Lyme disease.
