BACKGROUND Brainstem auditory evoked potentials (BAEP) are an objective test that provides an early detection of hearing losses and a functional evaluation of the auditory pathway. METHODS All neonates born between November 1989 and December 1994 presenting some factor of audiologic or neurologic failure were tested by ABR, in order to determine the prognostic significance of abnormalities on follow-up. RESULTS Of 40 selected babies 17 did not pass the former test and were classified as follows: eleven in a peripheral hearing loss group of mild-moderate degree and 6 in groups of severe peripheral hearing loss or central disorder of the auditory pathway. CONCLUSIONS On follow-up an ABR test was included disclosing that many of the mild-moderate peripheral abnormalities has a transitory nature. Infants included in the other two groups had a very poor outcome from the point of view of life expectancy and psychomotor development.

D005865	Gestational Age	The age of the conceptus, beginning from the time of FERTILIZATION. In clinical obstetrics, the gestational age is often estimated from the onset of the last MENSTRUATION which is about 2 weeks before OVULATION and fertilization. It is also estimated to begin from fertilization, estrus, coitus, or artificial insemination.

D012189	Retrospective Studies	Studies used to test etiologic hypotheses in which inferences about an exposure to putative causal factors are derived from data relating to characteristics of persons under study or to events or experiences in their past. The essential feature is that some of the persons under study have the disease or outcome of interest and their characteristics are compared with those of unaffected persons.

D012720	Severity of Illness Index	Levels within a diagnostic group which are established by various measurement criteria applied to the seriousness of a patient's disorder.	Illness Index Severities,Illness Index Severity
D015997	Neonatal Screening	The identification of selected parameters in newborn infants by various tests, examinations, or other procedures. Screening may be performed by clinical or laboratory measures. A screening test is designed to sort out healthy neonates (INFANT, NEWBORN) from those not well, but the screening test is not intended as a diagnostic device, rather instead as epidemiologic.
