An 87-year-old man was referred to our hospital for non-healing ulcers on the right third, fourth, and fifth toes. The patient was diagnosed with chronic limb-threatening ischemia. Pre-treatment angiography of the right lower extremity revealed inframalleolar lesions. ⋯ Angiography performed four days after therapy revealed significant improvement in microcirculation. One year after therapy, he managed to avoid major amputation and achieve wound healing. In addition, angiography revealed that the microcirculation was maintained.

An 84-year-old Japanese woman presented with left hemiplegia 8 months after completing chemotherapy for mantle cell lymphoma. Brain magnetic resonance imaging (MRI) revealed a hyperintense lesion extending from the right parietal lobe to the left parietal lobe. ⋯ Immunohistochemistry and John Cunningham virus (JCV) DNA-polymerase chain reaction indicated JCV infection. Therefore, a diagnosis of PML was made. 18F-THK5351 PET, indicative of activated astrocytes, clearly depicted PML lesions composed of reactive and atypical astrocytes. 18F-THK5351 PET may capture fresh progressive PML lesions better than MRI.

One patient with systemic sclerosis with index fingertip necrosis and another with probable systemic sclerosis with index and middle fingertip impending necrosis were successfully treated with ultrasound-guided median nerve block application on the affected side. The nailfold temperatures of the affected fingers measured using thermography were below 25°C. ⋯ Peripheral nerve block can be a basic treatment for fingertip necrosis. The thermographical observation of the extent and region in which the temperature increased is novel.

Objective This study investigated the prevalence of gastric epithelial tumor in Helicobacter pylori-uninfected subjects who underwent esophagogastroduodenoscopy (EGD) as part of an annual checkup. Methods A total of 20,540 EGD examinations of H. pylori-uninfected individuals (12,917 men, 7,623 women; mean age 51.5±9.2 years old) were performed between April 2016 and March 2023. The prevalence of gastric epithelial tumor discovery and the size and location of each lesion type were analyzed. ⋯ Each lesion was located at a specific site in the stomach characteristic of its type. Conclusion In the present H. pylori-uninfected subjects, the prevalence of gastric epithelial tumors found on an EGD examination was 0.28%. Endoscopic examination should be performed in H. pylori-uninfected individuals to detect such tumors in characteristic locations.

A Case of Successfully Treated Roseomonas mucosa-induced Peritonitis Diagnosed by Mass Spectrometry.
Roseomonas mucosa is difficult to identify using routine analytical techniques. We herein report a case of peritoneal dialysis (PD)-related peritonitis caused by R. mucosa identified using matrix-assisted laser desorption/ionization-time-of-flight (MALDI-TOF) mass spectrometry (MS). ⋯ She was successfully treated with ciprofloxacin and meropenem without catheter removal. To our knowledge, this is the first case of R. mucosa peritonitis in which technique failure has been avoided.
