A 53-year-old man presented with abdominal symptoms and a fever for 6 months and ascites and lower body edema for 2 months before visiting our clinic. Heart failure, renal failure, inferior vena cava or portal vein obstruction, cirrhosis, and malignancy were suspected, but none were present. ⋯ Since the patient's ascites were not satisfactorily controlled medically, a Denver peritoneovenous shunt was placed. As a result, the ascites volume was successfully controlled over an extended period.

A 49-year-old Japanese woman was admitted to our hospital with weight loss of 15 kg, nephrotic-range proteinuria (4.5 g/g. Cre), and hematuria over a 6-month period. ⋯ Thiamazole (30 mg) was started for the hyperthyroidism. Three months later, the thyroid function normalized, and two months later, the proteinuria and hematuria disappeared, suggesting that COVID-19 vaccination and these events were related.

We herein report a 12-year-old boy who presented with a fever, erythematous rash on the cheeks, back pain, and dysphagia. Blood tests revealed increased creatine kinase levels, and muscle ultrasonography (MUS) revealed characteristic fascial thickening in the lumbar paraspinal muscles, where myalgia was prominent. ⋯ Prednisolone and intravenous immunoglobulin therapy improved the clinical and laboratory parameters as well as fascial thickening. MUS is useful for evaluating fasciitis associated with anti-NXP2 autoantibodies and monitoring therapeutic efficacy.

Objective To survey the epidemiology of respiratory pathogens during the coronavirus disease 2019 (COVID-19) pandemic using multiplex polymerase chain reaction (PCR). Methods Specimens were assayed using multiplex nested PCR. Materials Specimens were obtained from outpatients who presented with symptoms of upper respiratory tract infection and asymptomatic outpatients who had contact with patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection at Tohoku Medical and Pharmaceutical University Hospital in Sendai, Japan, from November 1, 2020, to May 31, 2023. ⋯ We identified a larger number of SARS-CoV-2-positive specimens in patients ≥10 years old. In contrast, in patients 0-9 years old, we identified a larger number of specimens positive for rhinovirus/enterovirus than for other viruses. Conclusion In this study, we examined the epidemiology of circulating respiratory pathogens during the COVID-19 pandemic era.

Vanishing bile duct syndrome (VBDS) is characterized by bile duct degeneration and necrosis, which result in bile duct loss and bile stasis. A 70-year-old man had malaise after receiving celecoxib. Laboratory tests revealed elevated hepatobiliary enzymes. ⋯ However, his condition continued to deteriorate, and he died. An autopsy showed that liver regeneration was poor, and bile duct loss was exacerbated. The pathological autopsy findings were consistent with VBDS.
