Impact of Pneumocystis carinii and cytomegalovirus on the course and outcome of atypical pneumonia in advanced human immunodeficiency virus disease.

Patients undergoing bronchoscopy for possible pneumocystis pneumonia were studied retrospectively to characterize the impact of common viral pathogens on the course of advanced human immunodeficiency virus (HIV) disease and atypical pneumonia. In 327 episodes, Pneumocystis carinii was found in 220 (67%), cytomegalovirus (CMV) in 145 (44%), and herpes simplex virus in 16 (5%). Early deterioration in oxygenation and use of intensive care was less common in CMV-positive patients.

The impact of concomitant viral pathogens on the course of Pneumocystis carinii pneumonia.

A large retrospective study was conducted to evaluate the impact of culturing cytomegalovirus from the respiratory secretions of AIDS patients with Pneumocystis carinii pneumonia. Pneumocystis carinii was found in 220 (67%) of 327 episodes and cytomegalovirus was found in 106 (48%) of the P. carinii-positive patients.

Health care needs for children of the recently homeless.

Thirty families were surveyed at a shelter for the homeless in San Diego, California concerning the health care status and needs of their children. 56.7% of the families had no regular source of health care and 46.

Estimation of the daily intake of nitrates and nitrites which children one to six years old, who attend State Nurseries in the City of Havanna, may consume.

The knowledge of the amounts of nitrates and nitrites consumed by the child population is of great importance due to three fundamental aspects: Reduction of nitrates to nitrites. Relation of these to methemoglobinemia. Carcinogenicity of the N-nitroso compounds, of which nitrites are the precursors.
