BACKGROUND Carotid artery resection has been shown to yield a chance of cure in patients with advanced head and neck carcinoma involving the carotid artery. However, the criteria for the identification of those who are vulnerable to neurologic injury after resection have not been established. Interposition grafting may minimize the risk of neurologic(More)
OBJECTIVE MR imaging was prospectively correlated with pathologic findings to study whether MR imaging can differentiate viable from nonviable tumor tissue in the irradiated carcinoma of the tongue. SUBJECTS AND METHODS MR examinations were performed after radiation therapy in 21 patients with carcinoma of the tongue. All patients underwent either a total(More)
Analysis of gait in patients with acute unilateral peripheral vestibular disorders was performed using foot switches and electromyography, with the aid of a telemetry system. Among the eight parameters set for the analysis, the occurrence rate of abnormality in the coefficient of variation (CV) was the highest (78%) for the time from heel strike to forefoot(More)
Gait analysis was performed in patients with vestibular system disorders, using foot switches and electromyography. They were divided into three groups: 11 cases with vestibular neuronitis (VN), 10 cases with large acoustic neuroma (LAN) who had central lesion evidenced by neurotological examinations, and 10 cases with olivopontocerebellar atrophy (OPCA). A(More)
This study verified the occurrence of oxygen saturation alteration during endotracheal aspiration. Patients were adults aged from 17 to 70, admitted due to either neurologic diseases, neuro or abdominal surgical affections. All were devoid of pulmonary pathology. Suction endotracheal catheters numbers 12, 14, and 16 were used. Variation in oxygen saturation(More)
A comparative study on gait analysis comprising 11 patients with vestibular neuronitis and 10 patients with large acoustic neuroma was undertaken by the use of foot switches and electromyography. Central disorders in the neuroma group were evidenced by neurotological examinations. Fourteen healthy adults served as controls. Variables employed for the(More)
An experiment was carried out in guinea pigs to clarify the effect of unilateral section of cervical afferent nerve (C1-C3) upon optokinetic nystagmus and vestibular nystagmus induced by sinusoidal rotation. To produce optokinetic nystagmus and optokinetic after-nystagmus, a random dot pattern was utilized as visual stimulation at a speed of 30 degrees/s.(More)
