Audiologic and electroacoustic immittance measurements were obtained from each ear of 23 patients with rheumatoid arthritis and 13 normal control subjects. Audiologic findings revealed 14 patients with rheumatoid arthritis with hearing loss of either conductive (three patients) or sensorineural (11 patients) type, while only two control subjects(More)
To determine the frequency of eye and auditory complications and their relationship to drug dosage and iron stores in patients receiving deferoxamine, we studied 52 regularly transfused patients who received deferoxamine by subcutaneous or intravenous infusion in doses from 26 to 136 mg/kg/day, and whose serum ferritin levels of 185 to 17,775 micrograms/L(More)
The pre-, peri-, and postnatal histories for two infants who suffered respiratory distress syndrome (RDS) are presented. Each infant was diagnosed with RDS within 24 hours after birth, placed on high-frequency jet ventilation, and passed auditory brainstem response (ABR) screening prior to hospital discharge. Both infants were enrolled in a neonatal(More)
The hospital records for 100 cases of meningitis in which acute audiometric data has been obtained were reviewed. The incidence of sensorineural hearing loss was found to be 6%. The severity of hearing impairment varied from mild to profound and was frequently bilateral and irreversible. Two-cases showed asymmetrical involvement, and in one case, there was(More)
The Northwestern University Auditory Test Number 6 (NU-6) measure of speech discrimination was time compressed and presented to four age groups ranging from 54 to 84 years of age. Experimental stimuli were presented at sensation levels of 24, 32, and 40 dB to an equal number of right and left ears and male and female subjects. Results indicated that(More)
Tympanometry was performed before (preoperative) and after (intraoperative) the administration of inhalation anesthesia including nitrous oxide and halothane on 109 children undergoing myringotomy with pressure equalization tube insertion. A total of 213 preoperative tympanograms were compared with their intraoperative counterparts and the presence or(More)
A high-frequency admittance meter was developed and used to study the maturation of physiological function in the middle ear of neonatal golden hamsters (Mesocricetus auratus). The middle-ear input admittance in the frequency range of 0.8-1.8 kHz was measured in animals ranging in age from 6 to 69 days postpartum. Admittance magnitude was found to increase(More)
A review of patients with cholesteatoma at the Children's Hospital of Philadelphia from 1981 to 1986 yielded 161 children. Analysis of data from both outpatient and hospital charts revealed a higher incidence of males to females, and the peak incidence of cholesteatoma appeared to be in the 6-10 year age group. Otorrhea was the most common symptom; and on(More)
OBJECTIVE To quantify the intensity, spectral content, and duration of exposure for suction noise created during aspiration of middle ear fluid following myringotomy. DESIGN Case series. SETTING Tertiary care center. PATIENTS OR OTHER PARTICIPANTS Convenience sample of 245 myringotomies performed on 124 patients ranging in age from 6 months to 14(More)
Hearing sensitivity for an experimental group of 278 industrial workers who engaged in recreational shooting was compared with that of an age-matched control group of 278 nonshooting industrial workers to examine the effect of gunfire exposure on auditory thresholds. The influence of age and the number of unprotected gunshot exposures per year also was(More)
