Rethinking the Utility of the Audio-Only Encounter: A Case of Herpes Zoster Co-Infection in Asymptomatic SARS-CoV-2.

Background: Telemedicine with video communication has become commonly applied during and after the COVID-19 pandemic. While audio-only encounters are not allowed in Japan after August 2023. The Centers for Medicaid and Medicare Services (CMS) in the United States revised the telehealth policy to make the video visit standard.

Asymptomatic gastric anisakiasis detected in gastric cancer screening: A case report.

Anisakiasis is a parasitic disease caused by and has become an emerging zoonosis as preferences for eating raw or undercooked seafood have become more common. Few case reports of asymptomatic anisakiasis have been published to date. A 79-year-old asymptomatic man underwent esophagogastroduodenoscopy (EGD) for gastric cancer screening.

Detection of dengue virus nonstructural protein 1 (NS1) by using ELISA as a useful laboratory diagnostic method for dengue virus infection of international travelers.

Background: Dengue virus ( DENV) nonstructural protein 1 ( NS1) has been used as a novel diagnostic marker during the early phase of DENV infection.

Methods: Presence of NS1 antigen was examined using 336 serum samples obtained from 276 travelers returning to Japan from Asia, Central and South America, Pacific Islands, and Africa with dengue. Assay specificity was evaluated using 148 non-dengue samples.

Evaluation of disinfective potential of reactivated free chlorine in pooled tap water by electrolysis.

Tap water is one of the causative factors of hospital infections. We examined the disinfective potential of electrolysis and mechanism of disinfection, and clarified the disinfective effect of electrolysis on tap water contaminated with bacteria, and discussed its clinical applications. Tap waters artificially contaminated with Pseudomonas aeruginosa, Escherichia coli, Legionella pneumophila, and Staphylococcus aureus could be sterilized by electrolysis at 20-30 mA for 5 min.

Medium pH-dependent redistribution of the urease of Helicobacter pylori.

Helicobacter pylori is an aetiological agent of gastric disease. Although the role of urease in gastric colonization of H. pylori has been shown, it remains unclear as to where urease is located in this bacterial cell.
