Evaluation of Sarcopenia by Psoas Muscle Measurements in Bullous Pemphigoid: A Single-Institution Survey in Japan.

Bullous pemphigoid (BP) is a rare autoimmune blistering disease that primarily affects elderly individuals. Based on the Bullous Pemphigoid Disease Area Index (BPDAI) severity assessment, immunosuppressive drugs are recommended for severe cases that fall within the more than moderate classes. Sarcopenia, which is characterized by decreased skeletal muscle mass and function in elderly patients, is a progressive and widespread skeletal muscle disease.

Cancer-associated point mutations within the extracellular domain of PTPRD affect protein stability and HSPG interaction.

PTPRD, a well-established tumor suppressor gene, encodes the protein tyrosine phosphatase-type D. This protein consists of three immunoglobulin-like (Ig) domains, four to eight fibronectin type 3 (FN) domains, a single transmembrane segment, and two cytoplasmic tandem tyrosine phosphatase domains. PTPRD is known to harbor various cancer-associated point mutations.

Concordance in judgment of clinical borders of basal cell carcinomas in Japanese patients: A preliminary study of JCOG2005 (J-BASE-MARGIN).

Basal cell carcinoma is the most common type of skin cancer, and surgical excision with clear margins is the standard of care. Surgical margins are determined based on risk factors (high or low risk) for recurrence according to the National Comprehensive Cancer Network and Japanese basal cell carcinoma guidelines. The clarity of the clinical tumor border (well-defined or poorly defined) is considered a risk factor, and significant discrepancies in the judgment of clinical tumor borders among dermato-oncologists may occur.

Two cases of Hailey-Hailey disease effectively treated with apremilast and a review of reported cases.

Hailey-Hailey disease (HHD) is an autosomal dominant genetic disease caused by a mutation of the ATP2C1 gene. Corticosteroids, antibiotics or cyclosporine have been administered to reduce inflammation and prevent flare-ups, but the efficacy is not always sufficient. We herein report two cases of HHD effectively treated with apremilast and review the previous literature.

Observation policy for sentinel node metastasis of melanoma: Comparative study with completion lymph node dissection in Japanese patients.

Based on the results of international multicenter randomized trials, completion lymph node dissection for patients with sentinel lymph node-positive melanoma is no longer routinely recommended. However, clinicians should take into consideration racial and medical resource differences when applying this evidence to clinical practice in Japan. To evaluate the clinical validity of the observation policy of omitting completion lymph node dissection, we retrospectively surveyed patients with sentinel lymph node-positive melanoma between 2002 and 2020 at Niigata Cancer Center Hospital.

Dermatologist's role in a cancer hospital: An overview of in-hospital consultations.

As cancer treatment advances, the need for dermatologists in the treatment process is increasing. Cancer patients often experience cutaneous manifestations of internal diseases and dermatological adverse events from chemotherapy, radiation, surgery, and stem cell transplants. These diminish patients' health-related quality of life and negatively affect cancer treatment adherence.

Photocatalytic Giese-Type Reaction with Alkylsilicates Bearing C,O-Bidentate Ligands.

Herein, a photocatalytic Giese-type reaction with alkylsilicates bearing C,O-bidentate ligands as stable alkyl radical precursors has been reported. The alkylsilicates were prepared in one step from organometallic reagents. Not only primary, secondary, and tertiary alkyl radicals, but also elusive methyl radicals, could be generated by using the present reaction system.

Trends in the prognosis of metastatic melanoma in the era of targeted therapy and immunotherapy: A single-institution survey in Japan.

Advances in anticancer therapy, including the development of targeted therapy and immunotherapy, have drastically changed treatment options for metastatic melanoma. However, to date, only a few studies have been published that directly compare overall survival (OS) before and after introduction of these new therapeutic options in Japan. We retrospectively surveyed patients with metastatic melanoma treated in our hospital between 1989 and 2019 to investigate the OS benefit of the new therapies.

Suzuki Coupling Reactions Catalyzed by PdO Dispersed on Dealuminated Y Zeolite in Air under Ambient Conditions.

Suzuki coupling reactions are performed using PdO loaded on dealuminated Y (USY) zeolite. The reaction between bromobenzene and phenylboronic acid is complete in 15 min at room temperature in air, with a turnover number of 1300. The reaction can be repeated at least five times by using 1 wt % Pd.
