Aims/introduction: The study aim was to investigate sulfonylurea prescription patterns in elderly patients (age ≥65 years) with type 2 diabetes mellitus in Japan. Sulfonylurea use among older adults has been insufficiently examined, despite the associated risks of hypoglycemia.

Materials And Methods: This retrospective cross-sectional survey entailed analysis of Japanese pharmacy data, extracted from the Musubi database, for patients (age 20-100 years) prescribed sulfonylureas between November 2022 and October 2023.

Objective: To clarify of the features of sessile serrated adenoma/polyp (SSA/P) observed with image-enhanced endoscopy using immunohistochemical staining.

Materials And Methods: Twenty-five hyperplastic polyps (HP) and 46 SSA/P were studied with autofluorescence imaging (AFI) and magnifying endoscopy with narrow-band imaging (ME-NBI). AFI color change, capillary dilatation, existence of a mucous layer on the tumor surface, and pit dilatation under ME-NBI were examined retrospectively.

We report the case of a 26-year-old male who presented with acute pancreatitis during the course of treatment for pancolitic ulcerative colitis (UC) with a time-dependent mesalazine formulation, prednisolone and azathioprine (AZA). Despite a review of his clinical history and various tests, the cause of pancreatitis could not be determined. Since drug-induced pancreatitis was considered possible, administration of the time-dependent mesalazine preparation and AZA was discontinued, and conservative treatment for acute pancreatitis was performed.

Sensory rhodopsin II is a seven transmembrane helical retinal protein and functions as a photoreceptor protein in negative phototaxis of halophilic archaea. Sensory rhodopsin II from Natronomonas pharaonis (NpSRII) is stable under various conditions and can be expressed functionally in Escherichia coli cell membranes. Rhodopsins from microorganisms, known as microbial rhodopsins, exhibit a photocycle, and light irradiation of these molecules leads to a high-energy intermediate, which relaxes thermally to the original pigment after passing through several intermediates.

A 75-year-old Japanese woman with polycythemia vera was admitted to our hospital in January 2003 with suspected pulmonary thromboembolism. After administration of heparin, platelet count decreased from 1,694 x 10(9)/l on admission to 60 x 10(9)/l on hospital day 14. The patient developed acute limb embolism and transient cerebral ischemic attack on days 17 and 25, respectively.
