Transitory otoacoustic emissions (TOAE) were analyzed in 48 ears of male hunters (age range: 30-45 years: mean age: 37 years) and in a population with normal hearing. All the ears had TOAE. The incidence of TOAE for the 1, 2, 3, 4, 5 and 6 KHz frequential bands was significantly lower in hunters than in the normal subjects (p < 0.001). The mean amplitude of(More)
CONCLUSION A reduction in the percentage of correct responses in the olfactory test indirectly indicated increased albuminuria and worse glomerular filtration rate (GFR) in diabetic patients. The olfactory function test is an indirect indicator of early microvascular complications in diabetic patients. OBJECTIVES Diabetes mellitus is a highly prevalent(More)
A light microscopic study of the spiral ganglion was done in human embryos and fetuses measuring 45, 50, 60, 74, 90, 134, 270 mm crown-rump length (crl), and in a one-day-old neonate. Morphometric evaluations of i) cell and nuclear area, ii) nuclear area/cell area ratio, iii) ganglion area, iv) cell concentration/surface unit, and v) distance between the(More)
OBJECTIVE To examine electrophysiological data from auditory brainstem responses (ABRs) and distortion product otoacoustic emissions (DPOAEs) in chickens following acoustic overstimulation. MATERIAL AND METHODS A total of 15 white 15-day-old Leghorn chickens were used. The animals were anesthetized with Equithensin, and placed with their heads in a(More)
CONCLUSION In Scarpa neurons the cell and nuclear area increases and nuclear/cytoplasm ratio decreases with fetal age (p < 0.0001). There are statistically significant differences in cell area between all fetal groups, except for the interval 45-74 mm crown-rump-length (CRL). Displacement of a neuron within the internal auditory meatus (IAM) occurs from 9(More)
Prospective and retrospective morphometric CT (axial and coronal) research was performed with 100 healthy persons and 163 patients (145 males, 118 females, mean age 50 years, range 1-88 years). The patients were classified into the following groups: chronic sinusitis (n = 85), polyposis (n = 25), mucoceles (n = 13), benign tumors (n = 20) and malignant(More)
Distortion products (DP) were recorded and a morphological cochlear study was made of a sample of 60 ears from chickens (Gallus domesticus. Leghorn breed) and the ages of 15, 23, 29 and 60 days, after intoxication by intramuscular gentamicin injection (40 mg per kg weight and day for 8 days). Spontaneous or transitory otoacoustic emissions were not obtained(More)
A microanalytical study of human auditory ossicles was performed in 11 normal adults, 13 infants, 13 foetuses, 7 middle ear cholesteatoma, 7 chronic otitis and 1 facial nerve schwannoma. Malleus and incus ossification is initiated in the foetal period, the Ca/P ratio reaching a value of 1.8-1.9 in the 29-gestation-week foetus and continues in the infant(More)
In this study we have analyzed the incidence, range, frequency spectrum and threshold of distortion products in a sample of 232 normal hearing person. 116 younger adults, 58 female ranging in age from 18 to 30 years (mean age 23.1) and 58 males ranging in age from 18 to 32 (mean age 23.7) were included in the study. In all the ears studied, the presence of(More)
The incidence, amplitude and frequency spectrum of transitory otoacoustic emissions (TOAE) were analyzed in a sample of 232 normal hearing ears, after click stimulation to determine normal parameters. 116 subjects, 58 female ranging in age from 18 to 30 years, mean age 23.1 years, and 58 male were from 18 to 32 years, mean 23.7 years, were included in this(More)
