OBJECTIVE:To assess the functional status of the otolithic pathway in vestibular migraine by comparing the results of static and dynamic subjective visual vertical and horizontal [subjective visual vertical (SVV) and subjective visual horizontal (SVH)] testing in patients with vestibular migraine with that of normal individuals. MATERIALS and METHODS:This hospital-based prospective study was conducted in 82 normal adults and 66 adults with vestibular migraine. The SVV and SVH angles were measured under static and dynamic conditions using a software-based test protocol. The arithmetic mean of six readings in each situation was considered. The results were further analyzed by stratifying cases and controls into two age groups 20-40 years and 41-60 years and into gender. RESULTS:The clinical profile of the patients with vestibular migraine was comparable to the available literature. The dynamic SVV and SVH in both age groups and the static SVH in the 41-60 years age group were significantly higher compared to normal individuals (p<0.05). The dynamic SVV and SVH were significantly higher in the cases compared to controls among both males and females (p<0.05). CONCLUSION:There is evidence of otolithic pathway abnormalities in individuals with vestibular migraine. The inclusion of SVV and SVH testing for the evaluation of patients with vestibular migraine may be useful in the interpretation and rehabilitation of symptoms in these patients.

Shwannoma, better known as neurilemmomas, are benign, slow growing, usually solitary and encapsulated tumor, originating from Schwann cells of the nerve sheath. They are exceedingly rare in the base of tongue and, therefore, not immediately thought of as a differential diagnosis of oropharyngeal tumors. However, the key to the diagnosis lies in the histopathologic examination. A number of surgical approaches have been proposed for tongue base Schwannomas with varying degree of postoperative morbidity. We report a case where a 19-year-old woman presented to us with progressive dysphagia, occasional dysarthria, and was found to have a large tongue base lesion. Diagnosis was confirmed by imaging studies and biopsy. Transoral laser assisted excision of the tumor was done. Histologic identification of Antoni A and B areas along with strong and diffuse staining with S-100 stain confirmed the diagnosis of Schwannoma.

We experimentally study the dynamics of two identical air bubbles rising side-by-side in water by varying two parameters, namely, the radius of the bubble and center to center distance between them. The bubbles follow a three-dimensional spiraling motion, and their path and shape oscillations are observed in both the front and top views by using a high speed camera with a back-lit illumination and a mirror arrangement. Bubbles of different sizes are created by using a dumping cup mechanism, and the center to center distance between the two bubbles is varied by using telescopic joints. The dynamics of the two side-by-side bubbles is compared and contrasted with that of a single rising bubble. We found that the bubbles act independent of each other, like a single bubble, when the center to center distance is greater than seven times the radius of the bubbles. For similar separation distances, increasing the size of the bubbles results in a smaller terminal velocity and also lesser deviation from a spiral path due to high inertia.
