BACKGROUND We hypothesized that the integrity of white matter might be related to the severity of freezing of gait in age-related white matter changes. METHODS Twenty subjects exhibiting excessive hyperintensities in the periventricular and deep white matter were recruited. The subjects underwent the Freezing of Gait Questionnaire, computerized gait(More)
BACKGROUND AND PURPOSE Patients with extensive leukoaraiosis are at high risk for vascular dementia. However, these patients exhibit variable severity of global cognitive impairment correlating with callosal atrophy. We hypothesized that callosal atrophy may reflect the severity of HDWM tract damage, which may explain global cognitive impairment. The(More)
BACKGROUND AND PURPOSE The aim of this study is to investigate whether angiographic demarcation of an occlusive lesion may predict successful or failed result of intra-arterial thrombolysis in acute middle cerebral artery (MCA) occlusion. METHODS We reviewed retrospectively the angiography and clinical data of acute MCA occlusion patients who underwent(More)

Surgical site infection (SSI) is an emerging problem in all fields of surgery, as well as in neurosurgery, with numerous strategies against SSI initiated in many countries. In this report, we describe a case of SSI caused by Neisseria subflava a month after ventriculostomy placement for acute hydrocephalus. A 53-year old man was referred to our hospital,(More)
We describe the impairment of eye movements during REM sleep in a patient with internuclear ophthalmoplegia. A 75-year-old woman, complaining of acute unsteady gait and diplopia, was diagnosed to have right medial longitudinal fasciculus (MLF) syndrome with limited adduction of the right eye. Overnight polysomnography revealed the same impairment of right(More)
We report two unusual cases of rectus sheath hematoma. This condition usually presents with acute onset and is generally treated through the general surgery or emergency service department. However, if the hematoma grows slowly it may be diagnosed as an abdominal tumor and the patient may then be referred to the plastic surgery department.
We report a 30-year-old man with temporal lobe epilepsy associated with hypocalcemia due to primary hypoparathyroidism. He had frequent jamais vu since age 14 years, and later developed generalized convulsive seizures. It was initially controlled by phenytoin. The patient also had hypocalcemia due to primary hypoparathyroidism. The presence of jamais vu(More)
