A natural history study of pneumococcal infection in 82 infants followed from birth is reported. Longitudinal carriage patterns were determined by serial throat and nasopharyngeal cultures. Seventy-nine of 82 infants carried one or more types during the study period. The first type was acquired by a mean age of six months, and the duration of carriage(More)
Serotypes of Streptococcus pneumoniae from 525 infected children were examined over a four-year period. Type distribution was similar among 84 cases of bacteremia and 30 cases of meningitis, with types 6, 14, and 18 accounting for half of the illnesses. In contrast, half of 396 episodes of otitis media were caused by three other types, 19, 23, and 3. Four(More)
The relationship between nasopharyngeal carriage of Streptococcus pneumoniae types 3, 19, and 23 and the development of homotypic serum antibody was examined in 17 infants followed prospectively from birth. Serially drawn sera from these children and single serum samples from 18 normal adolescents were assayed for opsonizing antibody using reduction of(More)
OBJECTIVES/HYPOTHESIS The wound healing characteristics of incisions made with the short pulsed CO2 laser tuned to 9.55 microm versus the traditional 10.6 microm were investigated. Previous studies have shown that at 9.55 microm, collagen is targeted more selectively than at 10.6 microm, which results in decreased acute thermal injury patterns. This study(More)
A prospective study of the natural history of pneumococcal infection, which involves serial culture studies in healthy infants from 6 weeks of age onward, is in progress in our laboratory. This report describes results of a comparison of several methods for the isolation and identification of Streptococcus pneumoniae from the nasopharynges and throats of(More)
Active search is a learning paradigm with the goal of actively identifying as many members of a given class as possible. Many real-world problems can be cast as an active search, including drug discovery, fraud detection, and product recommendation. Previous work has derived the Bayesian optimal policy for the problem, which is unfortunately intractable due(More)
