Adult T-cell leukemia/lymphoma (ATL) is a peripheral T-cell malignancy with a poor prognosis. We conducted a retrospective study across six institutions in Miyazaki Prefecture, Japan, to assess the efficacy of tucidinostat in patients with relapsed/refractory ATL who had not undergone transplantation. Between October 2021 and July 2023, 24 patients aged 41 to 88 years (median, 73.

Objective: To evaluate the ability to discriminate giant cell arteritis (GCA) from Takayasu arteritis (TAK) according to the modified 2022 American College of Rheumatology/European Alliance of Associations for Rheumatology (ACR/EULAR) GCA classification criteria.

Methods: Patients enrolled in the Japanese nationwide retrospective registry were evaluated using the criteria with partial modification; wall thickening of descending thoracic-abdominal aorta were mainly diagnosed by contrast-enhanced computed tomography (CT) or magnetic resonance imaging instead of evaluating with positron emission tomography (PET)-CT. The discriminability of the criteria was evaluated using C-statistic (> 0.

Background And Aim: No prospective studies have verified the incidence of cholecystitis in patients using the covered self-expandable metallic stent. In this study, we aimed to investigate the incidence of cholecystitis and its risk factors after low axial force covered self-expandable metallic stent placement for malignant distal biliary obstruction.

Methods: This multicenter prospective study included patients diagnosed with unresectable distal biliary obstruction between November 2019 and October 2022 who underwent low axial force covered self-expandable metallic stent placement.

Objective: The objective of our study was to assess the efficacy of Rezum, a minimally invasive surgical treatment, for patients with lower urinary tract symptoms related to benign prostatic hyperplasia (BPH) in real-world clinical practice at a single institution in Japan.

Materials And Methods: We conducted a prospective study involving 100 patients who underwent the Rezum procedure between October 2022 and February 2024. We analyzed patient backgrounds that are compliant with Japanese regulations and assessed descriptive outcomes such as symptom scores, peak flow in uroflowmetry, post-void residual (PVR) volume, and prostate volume (PVol).
