Familial leuconychia, knuckle pads, hearing loss, and palmoplantar hyperkeratosis: an additional family with Bart-Pumphrey syndrome.

All studies on primary neural degeneration in the cochlea have evaluated the end stages of degeneration or the indiscriminate destruction of both sensory cells and cochlear neurons. We have developed a model which selectively simulates the dystrophic changes denoting cochlear neural degeneration while sparing the cochlear hair cells. Such a model can be used to define more precisely the mechanism of presbycusis or the hearing loss in aging man.Twenty-two pigmented guinea pigs (200-250 gm) were perfused by the perilymphatic route as live preparations using fluorocitrate in various concentrations (15-250 ug/cc) and at different incubation times (5-150 minutes). The barium salt of DL fluorocitrate, (C6H4O7F)2Ba3, was reacted with 1.0N sulfuric acid to precipitate the barium as a sulfate. The perfusion medium was prepared, just prior to use, as follows: sodium phosphate buffer 0.2M, pH 7.4 = 9cc; fluorocitrate = 15-200 mg/cc; and sucrose = 0.2M.

Hearing Problems

The teachers of 2231 elementary school children were asked to identify those with known or suspected hearing problems. Following screening, the data were compared. Teachers identified 5% of the children as hearing-impaired, while screening identified only 3%. There was agreement between the two procedures on 1%. Subsequent to the teacher interviews, rescreening and tympanometry were conducted. These procedures indicated that teacher screening and tympanometry were in agreement on 2% of the total sample or 50% of the hearing-loss group. It was concluded that teachers could supplement audiometry, particularly when otoscopy and typanometry are not available.

Hearing Problem

This report reviews 27 cases of children exhibiting functional hearing loss. The study reveals that most students were in the upper elementary grades and were predominantly females. These subjects were functioning below their ability level in school and were usually in conflict with school, home, or peers. Tests used were selected on the basis of their helping to provide early identification. The subjects' oral and behavioral responses are presented, as well as ways of resolving the hearing problem. Some helpful counseling techniques are also presented.
