A case of fatal disseminated infection with masticator space abscess caused by ESBL-producing K57-ST412 hypervirulent Klebsiella pneumoniae.

A 70-year-old Japanese man with well-controlled diabetes mellitus and chronic kidney disease was hospitalized for an examination of acute renal failure and elevated inflammatory reactions. He had a history of Klebsiella pneumoniae bacteremia without extended-spectrum β-lactamase (ESBL) production five months earlier. The patient was found to have bacteremia due to hypermucoviscous ESBL-producing Klebsiella pneumoniae, and developed septic shock, multiple cerebral infarctions, and an abscess in the left masticatory muscle space.

Chronic and Acute Drug-Induced Hypersensitivity Syndrome in a Rural Patient With Cytomegalovirus Infection: A Case Report.

A 50-year-old man presented with fever and a generalized rash, with chronic fatigue and lymphadenopathy for a year and a half.

Impact of the difference in diagnostic criteria for adolescent polycystic ovary syndrome excluding polycystic ovarian morphology.

Aim: Exclusion of polycystic ovarian morphology (PCOM) from the diagnostic criteria for adolescent polycystic ovary syndrome (PCOS) has been proposed. We analyzed the profiles of adolescent women with suspected PCOS based on the Japan Society of Obstetrics and Gynecology (JSOG) diagnostic and Rotterdam criteria, excluding those with PCOM.

Methods: Thirteen- to twenty-one-year-old women with suspected or confirmed diagnosis of PCOS according to the JSOG and Rotterdam criteria were included in this study.
