[Risk factors for home deaths due to pneumonia among low socioeconomic level Chilean children, Santiago de Chile (1994)].

Background: Pneumonia is the main cause of late infant mortality in Chile. Over 60% of these deaths occur at home. The lack of hospital beds and the inadequate outpatient management are contributing factors.

[Clinical epidemiological findings in infants who were dead on arrival to hospital].

This figure amounts for 24% of infant mortality rate of that area. Males under age 6 month were more frequently affected (61.

[Diagnostic strategy of acoustic neuroma. Evaluation of efficacy of auditory evoked potentials. Apropos of a series of 50 neuroma cases].

The authors carry out a retrospective study of the diagnostic procedures used in a series of 50 acoustic neuromas. AEP were performed for thirty-four neuromas at some stage of their history. The findings were perfectly normal for eight of them, which represents a sensitivity level of 76%.

Reversible hearing loss in a patient with cryptococcosis.

A 16-year-old girl had hearing loss, paroxysmal tremor, gait disorders, and psychiatric disturbances as the initial manifestations of a cryptococcal meningoencephalitis. Imaging demonstrated an obstructive hydrocephalus, and neuro-otological explorations showed a retrocochlear deafness and diffuse brainstem involvement. Emphasis is on the deafness, which rarely occurs as a presenting symptom in this condition, and on its dramatic improvement following antimycotic therapy.
