Monocyte chemoattractant protein-1 (MCP-1) levels are increased in scalp lesions of patients with alopecia areata (AA), suggesting a role in the development of AA. Recently, a biallelic A/G polymorphism in the MCP-1 promoter at position -2518 has been found, influencing the level of MCP-1 expression in response to an inflammatory stimulus. We investigated(More)
A 27-year-old woman who had been receiving propylthiouracil for 2 years for Graves' disease presented with painful ulceration on the lower limbs which had first appeared 2 weeks previously. Well-circumscribed hemorrhagic ulcerations with ragged borders were noted on both legs. Skin biopsy demonstrated a florid neutrophilic infiltrate and evidence of(More)
BACKGROUND Photodynamic therapy (PDT) is useful for the treatment of epidermal neoplasia but may also have use in the treatment of inflammatory dermatoses. The purpose of this study was to evaluate the safety and efficacy of PDT in the treatment of acne on the face. METHODS Eight patients with mild-to-moderate acne vulgaris on the face were treated with(More)
We compared the clinical efficacy of a short-term intervention of 308-nm excimer laser with that of narrow-band UVB (NBUVB) phototherapy for vitiligo patients to see the early response. Twenty-three symmetrically patterned patches of vitiligo on 8 patients were selected. Vitiligo patches on one side of the body were treated 2 times per week for a maximum of(More)
The three mammalian isoforms of transforming growth factor-beta(TGF-beta1, beta2, beta3) are potent regulators of cell growth, differentiation, and extracellular matrix deposition. To study their role in skin differentiation, we investigated the expression of TGF-beta isoforms on cell growth and differentiation induction of the human keratinocyte cell line,(More)
Acquired perforating dermatosis (APD) is a skin disorder occurring in the patients with chronic renal failure (CRF), diabetes mellitus (DM) or both. The purpose of this study was to clarify the clinical and histopathological features of APD, and evaluate role of scratching in the pathogenesis of APD. Twelve patients with APD associated with CRF and DM were(More)
