Small-vessel vasculitis associated with cholesterol embolism: a case report.

Background: Cholesterol embolism causes various organ dysfunctions, including skin, kidney, and gastrointestinal tract dysfunction, as well as immunological abnormalities, such as hypocomplementemia and eosinophilia. However, only a few cases of vasculitis accompanied by cholesterol embolism have been reported.

Case Presentation: We present the case of an 82-year-old man with cholesterol embolism who also developed small-vessel vasculitis of the skin and muscles.

Empyema caused by subsp. subsequently to bacteraemia.

subsp. (SDSE) commonly causes a variety of infections in older individuals. However, respiratory infections are uncommon.

Negative myoclonus as a manifestation of cefepime neurotoxicity.

Negative myoclonus may present in the early stages of cefepime neurotoxicity. Cefepime neurotoxicity typically presents as reduced consciousness, myoclonus, and seizures; however, negative myoclonus is uncommon. This video shows an older woman with cefepime neurotoxicity that presented as a negative myoclonus of the upper limbs.

Infective endocarditis and septic arthritis caused by Corynebacteriumstriatum.

Corynebacterium striatum occasionally causes nosocomial infections, such as catheter-related bloodstream infection and pneumonia; however, C. striatum-related infective endocarditis or septic arthritis is uncommon. We present the case of an 85-year-old woman with infective endocarditis at the native valve and septic arthritis at the native shoulder joint caused by C.

Immune-mediated Necrotizing Myopathy in a Patient with Microscopic Polyangiitis.

We herein report a case of immune-mediated necrotizing myopathy (IMNM) in a patient with microscopic polyangiitis (MPA). A 77-year-old Japanese woman presented with a 2-day history of proximal muscle weakness and myalgia, with elevated serum creatinine kinase (CK) levels. Findings of a muscle biopsy were compatible with IMNM; however, anti-signal recognition particle (SRP) and anti-3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMGCR) antibodies were negative.

A Flare of Hepatitis C Virus-Associated Cryoglobulinemic Vasculitis After COVID-19.

While undergoing treatment for hepatitis C virus (HCV)-associated cryoglobulinemic vasculitis (CV), a 53-year-old male contracted coronavirus disease 2019 (COVID-19), resulting in a disease flare. Although HCV became negative due to the use of glecaprevir/pibrentasvir, CV remained uncontrolled, and the patient was treated with prednisolone, azathioprine, colchicine, and rituximab. He had not been vaccinated against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

[Tetanus: the clinical features of 11 cases].

Tetanus is an infectious disease induced by wound invasion of Clostridium tetani, which is ubiquitous among soil. Many more cases are reported in Japan than in other developed countries. In this study, we report 11 cases of tetanus experienced at our hospital and discuss the preceding trauma and treatment course.
