Long-term efficacy of psoriasis vulgaris treatments: analysis of treatment with topical corticosteroid and/or vitamin D3 analog, oral cyclosporin, etretinate and phototherapy over a 35-year period, 1975-2010.

Various therapies have been tried for psoriasis. In Japan, biologics began to be used for psoriasis treatment in January 2010. Their clinical efficacy is well known, but biologics cannot be used in all psoriasis patients for reasons such as side-effects and cost.

Psoriasis affects patient's quality of life more seriously in female than in male in Japan.

Objective: The aim of this study was to assess the quality of life (QOL) of patients with psoriasis in Japan using Dermatology Life Quality Index (DLQI). Furthermore, we had evaluated the correlation between DLQI and clinical severity of psoriasis.

Methods: The Japanese version of DLQI was used to assess the QOL of patients.

Random skin biopsy of intravascular large B-cell lymphoma: a case report.

A 72-year-old woman visited our clinic with fever of unknown origin above 38°C and arthralgia from 7 months before. Her symptoms recurred as oral steroid was reduced. Random skin biopsy was carried out from five points.

A case of chromomycosis treated by surgical therapy combined with preceded oral administration of terbinafine to reduce the size of the lesion.

Chromomycosis is a chronic fungal disease of the skin and subcutaneous tissues caused by a group of dematiaceous black fungi. Small lesions can be removed with excision, but other cases are difficult to treat. We report a case of chromomycosis caused by Fonsecaea pedrosoi (F.

A novel splicing variant of CADM2 as a protective transcript of psoriasis.

CADM2, a candidate gene for psoriasis, was identified by a genome-wide association study using microsatellites in the Japanese population (561 cases and 561 controls). Moreover, haplotype analysis included an additional 68 SNPs and indicated that a 110-kb haplotype block was detected for the protective risk haplotype of psoriasis. We also identified an initial exon of novel splicing variants in this haplotype block.

Multiple Bowen's disease in a patient with a history of possible arsenic exposure: a case report.

A 81-year-old man with a patch of scaly erythema on his scrotum visited Hiratsuka Kyosai Hospital in June 2006. Reddish, scaly plaques, which were untreated, were present on his back and lower legs since 1999. Pathological examination of the lesions on the scrotum revealed Bowen's disease; therefore he was referred to our clinic for further treatment.

A novel case of nocardiosis with skin lesion due to Nocardia araoensis.

Nocardiosis is caused by gram-positive aerobic actinomycetes that live in soil and are known to be responsible for opportunistic infections. The condition mostly affects the lung, brain or skin. Here, we present a 24-year-old Japanese woman who had had systemic lupus erythematosus since the age of 20 years, and lupus nephritis since the age of 23 years.

Protein oxidative damage and heme oxygenase in sunlight-exposed human skin: roles of MAPK responses to oxidative stress.

Oxidative stress derived from ultraviolet (UV) light in sunlight induces different hazardous effects in the skin, including sunburn, photo-aging and DNA mutagenesis. In this study, the protein-bound lipid peroxidation products 4-hydroxy-2-nonenal (HNE) and the oxidative DNA damage marker 8-hydroxy-2'-deoxyguanosine (8OHdG) were investigated in chronically sun-exposed and sun-protected human skins using immunohistochemistry. The levels of antioxidative enzymes, such as heme oxygenase 1 and 2, Cu/Zn-SOD, Mn-SOD and catalase, were also examined.

Seborrheic keratosis that follows Blaschko's lines.

A 66-year-old Japanese man had skin lesions on the left side of his trunk and the left upper extremity for approximately 10 years. The skin lesions were asymptomatic but increased gradually, which brought the patient to our hospital. On the initial examination, we noticed 5 mm x 5 mm to 15 mm x 5 mm, round or oval, light to dark brown keratotic papules on the left side of chest and abdomen and the left upper extremity.

The incidence of internal malignancies in autoimmune bullous diseases.

Autoimmune bullous diseases are classified into pemphigus and pemphigoid. Pemphigus is designated as incurable disease by the Ministry of Health, Labor and Welfare, and it is said that pemphigus is difficult to care and can be fatal. The clinical course of bullous pemphigoid (BP) is better than that of pemphigus.

A case of implantation dermatosis that formed a tumor.

A 51-year-old man visited our hospital complaining of a tumor located above his lip. He had been hit on his upper left lip by a chopstick holder 2 months previously. The lesion turned into a tumor and gradually enlarged.
