Wound, Pressure Ulcer, and Burn Guidelines-5: Guidelines for the management of lower leg ulcers and varicose veins, second edition.

"Wound, Pressure Ulcer, and Burn Guidelines-5: Guidelines for the management of lower leg ulcers and varicose veins, second edition" is revised from the first edition, which was published in the Japanese Journal of Dermatology in 2011. The guidelines were drafted by the Wound, Pressure Ulcer, and Burn Guidelines Drafting Committee delegated by the Japanese Dermatological Association and intend to facilitate physicians' clinical decisions in preventing, diagnosing and management of lower leg ulcers and varicose veins. We updated all sections by collecting documents published since the publication of the first edition.

Health-related quality of life in patients with neurofibromatosis 1 in Japan: A questionnaire survey using EQ-5D-5L.

Neurofibromatosis 1 (NF1) is a genetic disorder characterized by various symptoms including dermatological, neurological, and osseous manifestations. These complications often cause cosmetic or functional disturbances, resulting in a significant impact on quality of life (QOL). However, there are limited data on QOL of individuals with NF1 in Japan.

Wound, pressure ulcer and burn guidelines - 1: Guidelines for wounds in general, second edition.

The Japanese Dermatological Association prepared the clinical guidelines for the "Wound, pressure ulcer and burn guidelines", second edition, focusing on treatments. Among them, "Guidelines for wounds in general" is intended to provide the knowledge necessary to heal wounds, without focusing on particular disorders. It informs the basic principles of wound treatment, before explanations are provided in individual chapters of the guidelines.

Distribution of diffuse plexiform neurofibroma on the body surface in patients with neurofibromatosis 1.

Neurofibromatosis 1 (NF1) is a genetic disease characterized by cutaneous, neurological and osseous abnormalities. Approximately 20% of patients develop plexiform neurofibroma (PN), resulting in impaired quality of life. To evaluate distribution of diffuse PN on the body surface, a retrospective study was conducted for 354 patients with NF1 from 2007 to 2018 in Japan.

Epidemiological Analysis of Major Complications Requiring Medical Intervention in Patients with Neurofibromatosis 1.

Neurofibromatosis 1 has various complications. To elucidate the frequency of neurofibromatosis 1-related major complications requiring medical intervention, a nationwide retrospective study was conducted of 3,530 patients with neurofibromatosis 1 registered from 2001 to 2014 in Japan. The ratio of certified patients requiring medical intervention (>stage 3) was 82%.

C-MYC and Its Main Ubiquitin Ligase, FBXW7, Influence Cell Proliferation and Prognosis in Adult T-cell Leukemia/Lymphoma.

Smoldering-type and chronic-type adult T-cell leukemia/lymphomas (ATLL) patients have relatively indolent clinical courses, but often progress into aggressive lymphoma-type and acute-type disease. We examined the roles of transcription factor C-MYC and its ubiquitin ligase FBXW7 in tumor tissues from 137 patients with ATLL. Immunohistochemical tests showed ≥50% of lymphoma cells in 78.

Nutritional, muscular and metabolic characteristics in patients with neurofibromatosis type 1.

Neurofibromatosis type 1 (NF1) has many reported clinical characteristics. We previously found that NF1 patients (especially men) had lower body mass index (BMI) than controls, but the reason has not been elucidated. To address this issue, a retrospectively case-control study was conducted.

Proactive treatment with calcipotriol reduces recurrence of plaque psoriasis.

Topical calcipotriol is a widely used treatment for plaque-type psoriasis worldwide, and has been shown to improve psoriatic plaques as well as very potent corticosteroids. However, there remains the practical question of whether calcipotriol application should continue on healed pigmentation/depigmentation associated with psoriatic plaques. Therefore, we conducted a pilot clinical study to answer this question.

Spontaneous regression of an epidermolysis bullosa nevus on the sole.

Epidermolysis bullosa (EB) is a group of inherited rare diseases characterized by fragility and blistering of the skin and mucous membranes. An EB nevus (EBN) is a very rare acquired nevus that occurs only in patients with EB. An EBN usually arises in an area of previous blistering, and frequently has an atypical appearance that mimics malignant melanoma.

Anthropometric characteristics and comorbidities in Japanese patients with neurofibromatosis type 1: a single institutional case-control study.

Neurofibromatosis type 1 (NF1) is a well-known genetic disorder characterized by café-au-lait spots and neurofibromas, but many other clinical characteristics and associated comorbidities also have been reported. This study aimed to characterize NF1 further by investigating its association with anthropometric characteristics and other diseases. We performed a case-control study of 227 NF1 patients (101 male, 126 female) and a randomly selected age- and sex-matched control group of 681 non-NF1 patients (303 male, 378 female) who visited our institution in Japan.
