RESUMO
A 31/2-year-old child presented with symptoms of acute gastroenteritis and evidence of central nervous system disease. Evaluation revealed findings consistent with meningoencephalitis and rotavirus detected in the cerebrospinal fluid by polymerase chain reaction. A review of the literature describes 23 cases of central nervous system disease attributed to rotavirus.

OBJECTIVE: Because most internationally adopted children come from areas of high tuberculosis prevalence, an initial tuberculin skin test is recommended after arrival to the United States. We evaluated whether repeat testing of children >or=3 months after arrival to the United States would identify additional children with latent tuberculosis infection. METHODS: Internationally adopted children who were seen at our International Adoption Center and had a tuberculin skin test within 2 months of arrival to the United States were eligible for the study. Children not diagnosed with tuberculosis with initial testing were retested at least 3 months later. The prevalence of tuberculosis on arrival and after repeat testing was determined, and potential risk factors for infection were examined. RESULTS: Of the 527 internationally adopted children with an initial tuberculin skin test completed, 111 (21%) had evidence of latent tuberculosis infection. Repeat tuberculosis testing was complete for 191 internationally adopted children (46.9% of those who had an initially negative tuberculin skin test). Latent tuberculosis infection was found in 20% of those who were retested. No children were found to have active tuberculosis disease. Children with an initially positive tuberculin skin test result had slightly higher weight-for-age z scores at their initial clinic visit, whereas those whose tuberculin skin test result was positive after repeat testing had slightly lower weight-for-age z scores. A strong correlation between BCG immunization and tuberculin skin test result was observed. CONCLUSIONS: Latent tuberculosis infection is common in internationally adopted children. A high proportion of internationally adopted children had an initially false-negative tuberculin skin test. Repeat tuberculosis testing of all internationally adopted children with an initially negative tuberculin skin test should be the standard of care for identifying tuberculosis infection and preventing tuberculosis disease in this high-risk population.

OBJECTIVE: The American Academy of Pediatrics recommended routine use of varicella vaccine in pediatric practice in 1995. We examined the impact of varicella immunization on population-based rates of pediatric varicella-related hospitalizations and emergency department (ED) visits in the years before and after introduction of varicella vaccine. STUDY DESIGN: Discharge data for hospitalizations and ED encounters from 1990 through 2003 were queried for patients <20 years of age with varicella International Classification of Diseases, Ninth Revision, Clinical Modification codes (052.0-052.9) in any diagnostic position. Addresses were geocoded for identification of Hamilton County, Ohio, residents. Rates were calculated according to year, age, and race, with census estimates. RESULTS: During the 14-year study period, there were 3983 incident varicella cases; 335 patients were hospitalized and 3833 were treated only in the ED. The rate of varicella-related hospitalizations decreased from 15.7 cases per 100,000 population to 5.5 cases per 100,000 population between the prevaccine period (1990-1995) and the postvaccine period (1996-2003); varicella-related ED use decreased from 178.2 cases per 100,000 population to 61.2 cases per 100,000 population. In the prevaccine period, hospitalization and ED visit rates were significantly higher for black children than for white children. In the postvaccine period, hospitalization rates did not differ according to race but ED visit rates remained significantly higher for black children, compared with white children. CONCLUSIONS: Varicella-related hospitalization and ED visit rates decreased significantly for both white and black children in Hamilton County, Ohio, after the introduction of varicella vaccine, and the racial disparity found before licensure decreased after licensure.
