A preliminary study of the relationship between central auditory processing disorder and attention deficit disorder.

Fifteen boys aged six to ten who met the criteria for attention deficit disorder (ADD) were compared with ten boys who did not have ADD in a double-blind, placebo-controlled, single-crossover study of methylphenidate. To assess the degree of overlap between ADD and central auditory processing disorder (CAPD), all subjects were assessed on parent and teacher behavior rating scales, as well as a battery of CAPD tests at baseline and after three and six weeks of treatment. Twelve of the 15 subjects with ADD and none of the subjects without ADD met the criteria for CAPD.

Pneumonia and pleural effusion. Association with influenza A virus and Staphylococcus aureus.

An 8-month-old infant with severe pneumonia and massive pleural effusions was found to have concurrent infections due to Staphylococcus aureus and influenza A virus. This was proved by the isolation of both agents from the pleural fluid. We believe this is the first case of isolation of an influenza virus from pleural effusions.
