Hereditary rimmed vacuole myopathy showing interstitial amyloid deposition in muscle tissue.

We describe a consanguineous family that had progressive myopathy with rimmed vacuole (RV) formation and amyloid deposition. Patient 1 is a 71-year-old woman with muscle atrophy in the lumbar girdle and lower extremities. Patient 2 is a 40-year-old man (the son of Patient 1) with fatty changes in the biceps femoris muscles.

Acute encephalitis caused by intrafamilial transmission of enterovirus 71 in adult.

Enterovirus 71 (EV71) is a common cause of hand, foot, and mouth disease and sometimes causes severe neurologic complications, mainly in children. We report a case of adult-onset encephalitis caused by intrafamilial transmission of a subgenogroup C4 strain of EV71. This case elucidates the risk for EV71 encephalitis even in adults.

Carotid duplex ultrasonography during head-up tilt in patients with orthostatic hypotension.

Orthostatic hypotension (OH) is defined by evaluating postural blood pressure (BP) change, but the correlation between postural BP decreases and OH-associated symptoms is poor. We examined carotid duplex ultrasonography during HUT in 27 patients with various neurological disorders. Nine patients were diagnosed to have OH, and 4 of them had symptoms associated with OH.

Acute urinary retention as an unusual manifestation of aseptic meningitis.

A formerly healthy 32-year-old woman was hospitalized for a closer examination of undiagnosed fever with mild headache. Despite lack of distinct findings on physical and laboratory examinations at admission, she suddenly developed anuresis due to acontractile neurogenic bladder. On the basis of her symptoms and the faint nuchal rigidity revealed later, as well as the results of cerebrospinal fluid analyses, a diagnosis of aseptic meningitis was eventually reached.
