Evidenced-based guidelines for management of infants and children with community-acquired pneumonia (CAP) were prepared by an expert panel comprising clinicians and investigators representing community pediatrics, public health, and the pediatric specialties of critical care, emergency medicine, hospital medicine, infectious diseases, pulmonology, and(More)
OBJECTIVES The precise epidemiology of childhood pneumonia remains poorly defined. Accurate and prompt etiologic diagnosis is limited by inadequate clinical, radiologic, and laboratory diagnostic methods. The objective of this study was to determine as precisely as possible the epidemiology and morbidity of community-acquired pneumonia in hospitalized(More)
The UspA1 and UspA2 proteins of Moraxella catarrhalis are structurally related, are exposed on the bacterial cell surface, and migrate as very high-molecular-weight complexes in sodium dodecyl sulfate-polyacrylamide gel electrophoresis. Previous analysis of uspA1 and uspA2 mutants of M. catarrhalis strain 035E indicated that UspA1 was involved in adherence(More)
OBJECTIVES To determine the etiology of community-acquired pneumonia in ambulatory children and to compare responses to treatment with azithromycin, amoxicillin-clavulanate or erythromycin estolate. METHODS Ambulatory patients with pneumonia were identified at the Children's Medical Center of Dallas, TX. Children age 6 months to 16 years with radiographic(More)
Microbiologic causes of meningitis include bacteria, viruses, fungi, and parasites. Before routine use of pneumococcal conjugate vaccine, bacterial meningitis affected almost 6000 people every year in the United States, and about half of all cases occurred in children 18 years old or younger. Prompt and accurate diagnosis and adequate treatment of bacterial(More)
STUDY OBJECTIVE To develop guidelines for the care of infants and children from birth to 36 months of age with fever without source. PARTICIPANTS AND SETTING An expert panel of senior academic faculty with expertise in pediatrics and infectious diseases or emergency medicine. DESIGN AND INTERVENTION A comprehensive literature search was used to identify(More)
The CSF half-lives of lipophilic agents, such as quinolones, are similar to those in serum and peak concentrations in CSF are achieved relatively quickly. In contrast, the pharmacokinetics of hydrophilic agents (beta-lactams and vancomycin) in CSF often differ from those in serum. In particular, the half-lives of these agents in CSF tend to be extended, and(More)
Clinical manifestations, diagnostic studies, and management of pyogenic sacroiliitis were reviewed in 77 pediatric patients. This infection occurs primarily in late childhood, is more common in boys, and has a subacute onset in about two thirds of cases. Recognition of the characteristic signs and symptoms of sacroiliac involvement coupled with radioisotope(More)
Results of CSF examinations from 117 high-risk neonates were reviewed. The mean CSF cell count was 8.4 cells/mm3 and the range was 0 to 32 cells/mm.3 Approximately 60% of the CSF WBC were polymorphonuclear leukocytes. Average CSF protein concentrations were 90 mg/dl (range, 20-170 mg/dl) in term and 115 mg/dl (range, 65-150 mg/dl) in preterm infants. The(More)
The medical records of children who had had CSF shunt procedures were reviewed for the seven-year period from 1975 through 1981. There were 516 procedures performed in 297 patients. Only three were ventriculoatrial shunts; the remainder were ventriculoperitoneal shunts. Fifty-nine infectious episodes (11%) occurred in 50 patients (17%); there were three(More)
