Based on striking parallels between the cell kinetics in the epidermal lesion of psoriasis and the proliferation of hair matrix keratinocytes during the anagen phase of the hair growth cycle, the hypothesis is proposed that both phenomena may share the same "switch-on" mechanism. Particular emphasis is placed on a comparison between the Koebner phenomenon in psoriasis and wounding-induced anage...

Many traditional and new musical instruments make use of an isomorphic note layout across a uniform planar tessellation. Recently, a number of hexagonal isomorphic keyboards have become available commercially. Each such keyboard or interface uses a single specific layout for notes, with specific justifications as to why this or that layout is better. This paper is an exploration of all possible...

were performed according to the guidelines of the Spanish Contact Dermatitis Research Group (abbreviated in Spanish to GEIDAC) using the standard GEIDAC series and a rubber series (Chemotechnique, Malmö, Sweden). Readings at 48 and 96 hours were positive (++) for the carba mix, the thiuram mix, the black rubber mix, tetramethylthiuram monosulfide, tetramethylthiuram disulfide, N-cyclohexylN-phe...

Linear IgA disease is an autoimmune subepidermal bullous disease in which linear IgA deposits are found at the basement membrane zone. It is classically idiopathic but may be drug induced. We report on a patient with drug induced linear IgA disease who exhibited certain unusual and interesting clinical features including isomorphic Koebner response, annular blister of the nipples and local insu...

OBJECTIVE Vitiligo usually presented as asymptomatic depigmented macules and patches. Little is known regarding itch in vitiligo. This study aimed to evaluate the prevalence and characteristics of itch in vitiligo patients. PATIENTS AND METHODS A cross-sectional study was conducted on vitiligo patients. Itch character and intensity were determined through questionnaires. Evaluation was also m...

Acute febrile neutrophilic dermatosis (Sweet's syndrome) is an uncommon inflammatory cutaneous disorder. It presents with lesions which are tender, erythematous, edematous papules and under histologic examination show dense neutrophilic infiltration of the dermis. These lesions are often accompanied by leukocytosis and fever. This paper reports a unique case of acute febrile neutrophilic dermat...

Surgical management of vitiligo is considered an excellent terapeutic option for recalcitrant cases, provided the disease is stable and there is absence of Koebner phenomenom. Among surgical modalities, Suction Blister Epidermal Graft is a low cost and effective option (65 to 100% repigmentation can be achieved in up to 80% of patients). We describe how it can be optimized by using an alternati...
