Ataxia and deafness in children due to bacterial meningitis.

Eight children with postmeningitis ataxia had detailed neurologic, audiologic, and neurovestibular evaluations. Prolonged fever, prolonged hyponatremia, or septic arthritis occurred in six during hospitalization. Severe to profound sensorineural hearing losses were present in seven of the children. Electronystagmography was abnormal in three of seven children. In seven children, the ataxia has persisted, but steady improvement has been observed during the course of repeated examinations. Hearing should be evaluated routinely in any child who develops meningitis.

Acute and chronic effects of ammonia burns on the respiratory tract.

Exposure to anhydrous ammonia can result in substantial injury to the respiratory system, eyes, and integument. In this retrospective study, we present the acute and chronic respiratory manifestations in 12 patients exposed to anhydrous ammonia as a result of the same accident. Survivors suffering significant ill effects are separated into two groups according to history and clinical course. One group of patients sustained exposure to high concentrations of ammonia over a short period of time. They manifested upper airway obstruction and required early intubation or tracheostomy. These patients recovered with few pulmonary sequelae and are presently in good pulmonary health. The second group of patients were exposed to lower concentrations of gas over a prolonged period of time and did not manifest upper airway obstruction. In this group of patients, however, significant long-term pulmonary sequelae are manifested.

The immotile cilia syndrome--one cause of persistent upper respiratory tract infection.

Four patients with persistent recurrent upper respiratory tract infections are presented. Electron microscopic studies of respiratory mucosal biopsies from these patients reveal ultrastructural abnormalities of cilia consisting of partial to complete loss of dynein arms, radial spoke disruption, and compound cilia. The concept of immotile cilia as an important cause of recurrent infections is receiving more attention. This study stresses the need for simple, rapid screening tests for cilial activity followed by electron microscopic evaluation in selected cases.

The longitudinal course of congenital rubella encephalitis in nonretarded children.

The neurologic course of congenital rubella syndrome was traced in 29 nonretarded children to 9 to 12 years. During the first two years, manifestations involved abnormal tone and reflexes (69%), motor delays (66%), feeding difficulties (48%), and abnormal clinical behavior (45%). Hearing loss was documented in 76%. From three to seven years, poor balance, motor incoordination (69%), and behavioral disturbances (66%) predominated. Hearing losses increased to 86%. Currently, at 9 to 12 years, 25 have residua which include learning deficits (52%), behavioral disturbances (48%), poor balance (61%), muscle weakness (54%), and deficits in tactile perception (41%). Two additional children now have hearing loss. The encephalitic manifestations of congenital rubella syndrome are diverse. Overriding problems differ at each phase of childhood. Current deficits influence progress in educational and home environments. For these children, adequate intelligence alone does not guarantee academic success.

Laryngotracheal stenosis: a 5-year review.

Twenty-seven children with varying degrees of laryngotracheal stenosis were treated at Texas Children's Hospital (TCH) from January 1984 to January 1989. Nineteen children had a residual airway demonstrable preoperatively, and following laryngotracheoplasty, 18 (95%) were successfully decannulated; all but 1 had a normal voice. Eight children had complete stenosis. Of these children, 6 could be decannulated, but 3 required a second laryngotracheoplasty. Four children now have voice abnormalities.

Acquired subglottic stenosis in children.

Subglottic stenosis is a disorder characterized by narrowing of the airway below the glottis or apposing edges of the true vocal cords. In a broad definition, the term may be used to describe airway compromise in the regions of the larynx or the trachea or both. In children, the stenosis is usually due to scar formation secondary to prolonged airway intubation, rather than to external trauma. The location and extent of the stenosis are highly variable; consequently, corrective measures need to be selected to suit the individual problem. In the present series of children, conservative treatment was adequate for lesser degrees of stenosis; those with more severe scarring required external laryngeal surgery. The preoperative evaluation and treatment plans are reviewed.

The otolaryngologist and the hearing aid delivery system: current federal regulations.

New proposed rules and regulations concerning trade practices for the hearing aid industry have been developed in response to political pressures from Congress and consumer groups. Revisions to the trade regulations proposed by the Federal Trade Commission (FTC) include (1) more stringent limitations in advertising, (2) written permission to sell a hearing aid at home or in the buyer's place of business, and (3) the right of a buyer to cancel a hearing aid sale, rental, or lease within 30 days. Testimony on hearings regarding this rule are being reviewed by the FTC presiding officer. Food and Drug Administration national standards for the labeling and sale of hearing aids became effective Aug 15, 1977. A medical evaluation by a licensed physician is required before a hearing aid may be sold. Fully informed adults may request a waiver of this requirement for religious or personal beliefs, but a medical evaluation is mandatory for persons under 18 years of age. A User Instructional Brochure, which lists several conditions for which medical advice is advised, must be reviewed with the prospective buyer. In the recognition that some physicians may be dispensers of hearing aids, the Judicial Council of the American Medical Association has recommended that a physician may dispense hearing aids if it is in the best interest of the patient, but that a physician should not be encouraged to retail hearing aids in his office if other adequate community facilities exist.
