This study compared the growth of homeless children with National Center for Health Statistics (NCHS) standards and with growth of age-matched domiciled children of similar income level. Homeless children (n = 167) had lower height percentiles when compared with domiciled children (n = 167; P less than .001) and when compared with NCHS standards (P less than .001). The weight-height percentiles of homeless children did not differ from NCHS standards; however, domiciled children had higher weight-heights when compared with the homeless (P less than .001) and with NCHS standards (P less than .001). After controlling via regression analysis for the effects of potentially confounding factors that affect growth, it was found that homeless children from larger families and with single mothers accounted for the lower height percentiles observed. After controlling for confounding factors, domiciled children still had increased weight-height percentiles when compared with the homeless group. Duration of homelessness was not associated with decreased height or weight-height among homeless children. Homeless children in this study exhibited a pattern of stunting without wasting which is characteristic of poor children experiencing moderate, chronic nutritional stress. They exhibited a greater degree of nutritional stress than domiciled children at a similar income level and than that reported in other groups of poor children in the United States. Preexisting social factors in the families of homeless children were important in explaining the observed growth abnormalities. Further exploration of the associations between social characteristics of homeless children and their families and the growth of these children is warranted

A rapid latex agglutination (LA) method was evaluated in 2401 consecutive pediatric patients presenting to an emergency service with suspected group A beta-hemolytic streptococcal pharyngitis. LA tests were performed by the treating physicians, who were not blinded to the clinical condition of the children and who made therapeutic decisions based on the results of the tests. When compared with anaerobic culture, the LA method had a sensitivity of 91%, a specificity of 82%, and a positive predictive value of 43%. There was a marked seasonal variation in the positive predictive value: 62% in winter and 16% in summer. However, even in peak streptococcal pharyngitis season (January to March), basing therapy on a positive LA test leads to the unnecessary treatment of a large number of patients. Therefore, we cannot recommend the routine performance of this test by all practitioners in all clinical settings

Varicella-associated arthritis represents an uncommon complication of varicella in children. In 20 previously reported cases, three were documented to be bacterial in origin. Viral isolation from synovial fluid was attempted in seven others, and varicella was isolated in just two. In all previous case reports, the arthritis occurred after or coincident with the onset of varicella. The current case is one in which joint involvement preceded the clinical onset of varicella. Clinicians should be alert to the possibility that varicella may manifest as an acute arthritis, even in the absence of the typical exanthem
