To examine the impact of the plasma homocysteine level on the anti-atherosclerotic effects of pitavastatin treatment, we retrospectively examined 59 patients who had a history of stroke and had been prescribed pitavastatin for the treatment of dyslipidemia at the Neurology department of Toho University Ohashi Medical Center Hospital. The patients were classified into two groups according to their homocysteine levels. Carotid artery plaque progression was determined before and after pitavastatin treatment.

We report a 71-year-old man with legionellosis, who presented with abducens nerve palsy, singultus, confusion, memory impairment, ataxia, and hyporeflexia. Legionella pneumonia was diagnosed on the basis of detection of Legionella pneumophila antigen in the urine. The cerebrospinal fluid was negative for the antigen and antibody, but an oligoclonal band was detected, and the IgG index was elevated.

Limb-girdle muscular dystrophy 2B and Miyoshi myopathy are characterized by muscle fiber necrosis caused by a defect in dysferlin and inflammatory changes. SJL/J mice are deficient in dysferlin and display severe inflammatory changes, most notably the presence of cytokines, which may be related to destruction of the sarcolemma. We tested the hypothesis that tumor necrosis factor (TNF) contributes to myofibril necrosis.

We report on the case of a 32-year-old woman with tuberculous meningitis (TBM) with electroencephalogram (EEG) output displaying triphasic waves (TWs). The EEG on day 8 revealed generalized slowing, frontal bilateral TWs, a background of 2Hz delta waves, and no epileptiform activity. The patient's condition improved slowly with antituberculosis chemotherapy treatment.

We describe a rare case of autoimmune polyglandular syndrome type 2 initially presenting as Addison disease and autoimmune thyroid disease, with subsequent development of autoimmune hepatitis and myasthenia gravis (MG) crisis in a Japanese woman. MG improved with oral prednisolone followed by plasmapheresis for immunoadsorption; thymectomy was not performed. Conventional treatment for MG was effective and safe in this case, in which there was positivity for human leukocyte antigen A23, B52, B62, DR11, and DR15.

The clinical features of familial Creutzfeldt-Jakob disease with a codon 200 point mutation [fCJD (E200K)] are similar to those of sporadic CJD (sCJD). MRI diffusion-weighted imaging (MRI-DWI) has been reported to be useful for the early diagnosis of CJD. We describe a Japanese fCJD (E200K) case in which thalamic symptoms were the initial manifestations.
