Branhamella catarrhalis is commonly considered a respiratory commensal but has recently been implicated as a pathogen, particularly in adults. Over a 28 month period, B. catarrhalis was isolated from bronchopulmonary secretions of 14 PICU patients with acute respiratory infections. Twelve patients had pneumonia and two had tracheitis. The mean age was 3.5 years. Seven patients had chronic cardiopulmonary disease including two who were immunosuppressed. Three had an acute underlying condition and four had no complicating medical problem. Polymorphs and Gram-negative diplococci on Gram stain were found in respiratory secretions of all patients. Twelve of 14 isolates produced beta-lactamase, and six patients had a second potentially pathogenic bronchopulmonary isolate. All patients were treated for B. catarrhalis infection and none died. When isolated in pure culture from bronchopulmonary secretions in symptomatic patients, B. catarrhalis should be considered a pathogen. When isolated in mixed culture, its pathogenic role is uncertain. We conclude that B. catarrhalis can be a bronchopulmonary pathogen in critically ill children with otherwise normal cardiopulmonary function as well as in those with chronic cardiopulmonary dysfunction. When administering antibiotics the high frequency of beta-lactamase-producing strains must be taken into consideration.

We performed an observational study of the antibiotic-prescribing behaviour of Sicilian general practitioners (GPs) in managing acute upper respiratory tract infections (URTIs). Seventy-six GPs from 25 towns, representing a patient population of 96,630, participated in the study between September 1995 and May 1996. These physicians issued 2038 antibiotic treatment courses for acute upper respiratory tract infections: 792 for acute pharyngitis, 531 for acute tonsillitis, 304 for acute laryngitis and tracheitis, 268 for suppurative and non-suppurative acute otitis media, 124 for acute sinusitis and 19 for acute rhinitis. Forty-nine different antibiotics were prescribed. The most commonly used therapeutic groups were macrolides (38.6%), cephalosporins (27.1%), a combination of penicillins with beta-lactamase inhibitors (15.7%) and extended spectrum penicillins (13.5%). For each of the above diseases, except rhinitis, more than 30 different antibiotics were used. The choice of the route of administration appeared to be influenced by the age of the patients and, significantly, by a subjective clinical assessment of disease severity rather than by any consideration of epidemiological information or evidence from clinical trials. The rather marked variation in antibiotic-prescribing pattern for URTIs among Sicilian GPs reflects lack of availability or knowledge of any local or national guidelines.
