Brachial radiculoplexitis is characterized by acute onset of shoulder and arm pain followed by weakness and sensory loss. Brachial radiculoplexitis by herpes zoster is a rare disease, which can be diagnosed by careful history, electrodiagnosis and MRI. It has remained uncertain about clinical characteristics, treatment, and prognosis. Better understanding of this disease helps earlier diagnosis and prompt treatment to minimize neurologic sequale. We present two cases of subacute brachial radiculoplexitis preceded by herpes zoster infection.

Autoimmune thyroid disease associated with Moyamoya syndrome has mostly been reported as Graves' disease, and not as Hashimoto's thyroiditis. We report a case of a 70-year-old man with right posterior cerebral artery territorial infarction and bilateral distal internal carotid artery occlusion, which suggests Moyamoya syndrome, but who was diagnosed as Hashimoto's thyroiditis.

BACKGROUND: Local steroid injection is used to treat carpal tunnel syndrome (CTS). The aim of this study was to evaluate the clinical and electrophysiological effects of local steroid injection in patients with CTS over a 3-months period. METHODS: Twenty-one patients (35 hands) with clinical and electrophysiological evidence of CTS were treated by injection of triamcinolone 40 mg to the carpal tunnel. Visual analog scale (VAS), Boston Carpal Tunnel Questionnaire (BCTQ), rates of paresthesia, night awakening, and electrophysiological studies were used as outcomes. Clinical and electrophysiological assessments were performed before, 1 and 3 months after treatment. RESULTS: Prior to treatment, 86% of patients complained of night awakening. At 1 and 3 months after injection, only 17% and 29% of the patients, respectively, had night awakening (p<0.001). All patients complained of paresthesia before the treatment. This symptom disappeared in 60% and 31% of the patients after 1 and 3 months, respectively (p<0.001). Compared to baseline, both BCTQ and VAS show significant improvement during the 3 months of the study (p<0.005). Although significant improvements in clinical parameters were shown, electrophysiological parameters were not significantly improved at 1 and 3 months. CONCLUSIONS: Local corticosteroid injection for the treatment of CTS provides significant improvement in symptoms for 3 months. On the other hand, no significant improvement was observed in electrophysiological parameters.

Glufosinate ammonium is the active ingredient in broad-spectrum contact herbicides such as BASTA(R) that inhibits the activity of glutamine synthetase, which is necessary for the production of the amino acid glutamine and for ammonia detoxification. Complications of glufosinate ammonium intoxication include gastrointestinal symptoms, loss of consciousness, convulsions, memory impairment, respiratory failure, and cardiovascular instability. We report herein a case of encephalopathy and reversible signal changes in the splenium of the corpus callosum, the bilateral corticospinal tracts, the hippocampi, and the cerebellar peduncles as seen in diffusion-weighted magnetic resonance imaging and fluid-attenuated inversion recovery images following BASTA(R) intoxication.

BACKGROUND: Cultural characteristics of taking care of patients with dementia in Korea are based on the influence of Confucianism on the lifestyle of Koreans. In addition, as the family size has been getting smaller, the number of old persons who live alone has been increasing. The purpose of this study is to examine the proportion of the elderly with dementia who live alone and demographics of caregivers when such patients live with their family. METHODS: From the multiple hospital-based cohort, 973 elderly patients with very mild dementia (Clinical Dementia Rating [CDR]=0.5), 1,056 patients with mild dementia (CDR=1) and 359 patients with moderate dementia (CDR=2) were recruited. We analyzed the proportion of the patients with dementia who live alone and the demographics of the caregivers if such patients live with and are taken care of by such caregivers depending upon the severity of dementia. RESULTS: The proportion of the patients with dementia who live alone accounts for about 40% of all elderly patients with dementia. Major age groups of caregivers are of 40s and 50s. Sons, daughters, and spouses were ranked in the said order in the proportion of caregivers according to their relationship to patients. CONCLUSIONS: Up to now, family members care for about 60% of elderly patients with dementia, which may suggest that from the objective viewpoint, direct burden borne by caregivers for old patients with dementia would be considerably high. On the other hand, about 40% of dementia patients live alone, implying that the social care system is needed for them.

Most postoperative maxillary cysts develop more than 10 years after a Caldwell-Luc operation. They can manifest with cheek pain, swelling and dental and visual symptoms. Brain imaging should be performed to distinguish trigeminal nerve compression from various other possible causes. It should be treated by surgical intervention to relieve the above-mentioned symptoms. We report a patient who presented with compressive trigeminal neuropathy caused by a postoperative maxillary cyst.
