Topical rapamycin as a treatment for fibrofolliculomas in Birt-Hogg-Dubé syndrome: a double-blind placebo-controlled randomized split-face trial.

Background: Birt-Hogg-Dubé syndrome (BHD) is a rare autosomal dominant disorder characterised by the occurrence of benign, mostly facial, skin tumours called fibrofolliculomas, multiple lung cysts, spontaneous pneumothorax and an increased renal cancer risk. Current treatments for fibrofolliculomas have high rates of recurrence and carry a risk of complications. It would be desirable to have a treatment that could prevent fibrofolliculomas from growing.

Penile pyoderma gangrenosum: successful treatment with colchicine.

Pyoderma gangrenosum is an ulcerative skin disease with variable clinical outcomes. The diagnosis is based on clinical features and exclusion of other ulcerative diseases. To date, a specific treatment is not known.

Erythema nodosum as an early sign of Crohn's disease.

Erythema nodosum is the most common form of septal panniculitis and the most frequent skin manifestation associated with inflammatory bowel disease. Since the development of erythema nodosum is closely related with a variety of disorders and conditions, it can serve as an important early sign of systemic disease. We report on a 25-year-old woman with Crohn's disease following a long history of recurrent erythema nodosum.

Secondary erythromelalgia involving the ears probably preceding lupus erythematosus.

Secondary erythromelalgia is a rare disease characterized by burning pain, marked erythema, edema, and hyperthermia of the affected limbs. Secondary erythromelalgia can be associated with various systemic diseases. Here, we describe a patient who developed secondary erythromelalgia involving the ears and concomitant clinical and laboratory, probably, indicating the initial stage of a developing lupus erythematosus.

Gamma-linolenic acid supplementation for prophylaxis of atopic dermatitis--a randomized controlled trial in infants at high familial risk.

Background: Studies suggest that low concentrations of n-6 long-chain polyenes in early life are correlated to atopic disease in later life.

Objective: The purpose of the study was to investigate the possible preventive effect of gamma-linolenic acid (GLA) supplementation on the development of atopic dermatitis in infants at risk.

Design: In a double-blind, randomized, placebo-controlled trial, formula-fed infants (n = 118) with a maternal history of atopic disease received borage oil supplement (containing 100 mg GLA) or sunflower oil supplement as a placebo daily for the first 6 mo of life.
