Acute bronchiolitis in tropical Africa: a hospital-based perspective in Ibadan, Nigeria.

In a 30-month prospective study of severe acute lower respiratory infections in hospitalized pre-school Nigerian children, acute bronchiolitis was diagnosed in 67 cases; 19 (28.4%) and 2 (3.0%) of these had concomitant pneumonia or croup, respectively.

Device-day infection rates - a surveillance component system for intensive care units at Security Forces Hospital, Riyadh, Saudi Arabia.

A surveillance component system for Intensive Care Units (ICUs) designed to account for major extrinsic risk factors for nosocomial infections using device days as the denominator has been advocated. A study of the surveillance component system in ICUs was conducted in Security Forces Hospital (SFH), Riyadh, Saudi Arabia, from February 1993 to January 1994 to verify the validity and compare the device-related infection rates with the infection rates based on patient admission and patient days. The standard recommended method was used in data collection.

Staphylococcal lower respiratory infection in children.

A prospective study of staphylococcal lower respiratory infection in 31 children aged 1-48 months has shown that radiologically, patchy consolidation was the single most common lesion, followed by pleural effusion with or without pneumothorax. Although the mean respiratory rate was 65/minute, it was below 50/minute in 8 cases. Complications include heart failure in 9 cases and severe anaemia necessitating blood transfusion in 9 others, seven (78%) of whom had pleural effusion.

Evaluation of the Rosco system for the identification of Listeria species.

The Rosco system was used to identify previously confirmed isolates of the seven currently recognised species of Listeria. These included reference cultures and recent isolates from clinical material, food products and environmental sources. The system identified all correctly.
