Diaphoresis and Meniere's disease.

The effect of diaphoresis on patients with Meniere's disease (labyrinthine hydrops) previously has not been reported. With the use of two distinct activities to produce diaphoresis, we were able to document substantial transient improvements in pure-tone threshold, speech-reception threshold, and speech discrimination concurrent with a decrease in tinnitus and fullness in two patients with unilateral Meniere's disease that had been diagnosed previously by the glycerin test. The two diaphoretic activities were (1) strenuous exercise, including periodic visits to the sauna, and (2) passive activity consisting of repetitive visits to the sauna.

Eye-head coordination: an observation.

Voluntary or passive head movements in normal and awake individuals with or without visual clues other than prior visual fixation, produce an occular movement in the same direction as the head movement rather than the expected counter gaze movement.

The efficacy of "conservative" medical regimens on the rate of hearing losses in Meniere's syndrome: a retrospective computerized statistical analysis.

The records of 47 patients with Ménière's syndrome were analyzed in a retrospective computerized study to determine the effect of different medical regimens on the long term course of hearing loss. Four treatment groups, including histamine (subcutaneous), other vasodilators (oral), vitamins, and untreated controls were examined. Results suggest that there was no statistically significant difference among the four groups in the rates or absolute level of hearing loss or SRT despite different therapeutic regimens.

Pre and post-glycerol special audiometric tests battery results in endolymphatic hydrops.

The glycerol test for endolymphatic hydrops was administered to 17 patients exhibiting classical symptoms of Meniere's disease. A complete battery of audiometric tests including the SISI, TTD (Rosenberg variation). ABLB, Sweep Frequency Bekesy, two tests of speech discrimination (Rush Hughes and Northwestern), and air and bone conduction thresholds were administered pre and post-glycerol ingestion in order to determine the effect of osmotic diuresis.

Caloric and optokinetic nystagmus in cerebellar patients.

In certain cerebellar lesions, optokinetic tracking is deficient, especially on tracking or following to the ipsilateral side. However, in many cases optokinetic nystagmus can occur, and apparently in better degree than would be expected from a study of pendulum tracking. This may be due to the patient leading into the stimulus and picking it up as soon as it is presented in far lateral gaze (in the direction of the fast component) and allowing the drift caused by the tone deficit to assist the tracking.

Ocular motor dysfunction in total and hemicerebellectomized monkeys.

Studies of ocular motor function in monkeys undergoing either total or hemicerebellectomies has revealed the following abnormalities which can be attributed to cerebellar dysfunction: 1. Loss of smooth pursuit movements 2. Gaze-fixation nystagmus 3.

Vestibular involvement in Bell's palsy.

Vestibular involvement in the acute phase of idiopathic facial paralysis (Bell's palsy) was observed in 22 percent and 14 patients. These patients were evaluated by history, physical examination and caloric tests with electronystagmography (ENG) employing the Cawthorne-Hallpike technique. Bell's palsy has been considered a mononeuropathy limited to the facial nerve.

Carcinoma of the esophagus.

Life tables were computed from the Tumor Registry at the Medical University of South Carolina on 486 patients with histologically proven squamous cell carcinoma of the esophagus. The 5-yr follow-up was available in only 394 patients, or 81% of the total sample. For purposes of comparison with published literature, the traditional crude 5-yr survival percentages in the life-table analyses figures are presented.

Modes of vestibular habituation.

An experiment was designed to investigate the effect of different modes of vestibular habituation. Volunteers were divided into two groups differing only in visual fixation. A theoretical explanation of the observed differences in nystagmus speed and frequency of beats between groups is offered.
