A 44-year-old woman was admitted to our hospital with a fever, dizziness, and gait disturbance after undergoing allogeneic hematopoietic stem cell transplantation for acute myeloid leukemia followed by graft-versus-host disease. She presented with cerebellar ataxia, nystagmus, and numbness of the lower extremities. Brain magnetic resonance imaging and perfusion scintigraphy showed progressive cerebellar involvement. ⋯ Anti-ganglioside antibodies were detected, but their levels did not follow the patient's clinical course. The patient did not respond sufficiently to steroids or other immunotherapies. We herein report the clinical characteristics of this case and a literature review.

A 42-year-old Japanese woman was admitted for the evaluation of proteinuria. She had a history of four habitual abortions and valvular heart disease, including severe mitral regurgitation and moderate tricuspid regurgitation. ⋯ Although the standard test for antiphospholipid (aPL) antibodies was negative, the patient was diagnosed with antiphospholipid syndrome (APS)-related disease by testing for phosphatidylserine dependent anti-prothrombin anticardiolipin antibody, a non-criterial aPL antibody. A kidney biopsy may lead to a diagnosis of APS in patients with negative laboratory test findings for APS.

Anti-mitochondrial antibody (AMA)-associated myopathies represent a homogeneous disease entity with severe arrhythmia and slowly progressive proximal muscle weakness with lordotic posture, irrespective of the presence of primary biliary cholangitis (PBC). We herein report a case of myositis associated with PBC without AMAs. ⋯ PBC, ascertained by a liver biopsy performed based on mildly elevated liver enzymes, and the efficacy of steroid therapy on muscle weakness confirmed the diagnosis of immune-mediated myositis. When AMAs are negative, a liver biopsy is indispensable for diagnosing treatable PBC-associated myositis.

Objective The present study evaluated the strategic role of percutaneous transhepatic gallbladder aspiration (PTGBA) for acute cholecystitis (AC) induced by a metallic stent (MS) placed in a malignant biliary stricture in comparison with percutaneous transhepatic gallbladder drainage (PTGBD). Methods The treatment outcomes for 31 patients who underwent PTGBA as the initial intervention for MS-induced AC were evaluated and compared with those for 12 who underwent PTGBD. Results The technical success rate was 100% for both groups. ⋯ In the PTGBA group, the clinical success rate was significantly higher for patients without cancer invasion to a feeding artery of the gallbladder than in those with invasion (75% without invasion vs. 29% with invasion; p=0.036). According to the multivariate analysis, this factor was an independent factor for clinical success of PTGBA (odds ratio, 9.27; p=0.040). Conclusion Although the clinical success rate of PTGBA for MS-induced AC was lower than that of PTGBD, PTGBA remains a viable option because of its safety and procedural simplicity, especially for cases without tumor invasion to a feeding artery.

Multiple myeloma (MM) is a cancer characterized by the expansion of plasma cells in the bone marrow. Survival times of patients with MM have increased due to the development of novel therapeutic agents. ⋯ The outcome for patients with MM showing high levels of serum ammonia continues to be poor, even with the use of novel therapies. For such patients showing a consciousness disorder, hyperammonemia should be considered as a possible cause.
