Adverse Drug Events Leading Children to Hospital Emergency Care

To determine the incidence of adverse drug events (ADE) that resulted in the need for children's emergency care, a total of 23,286 pediatric emergency case notes were analyzed. They were selected on the basis of the ICD code indicating a possible ADE. ADEs were found in 13 case notes (0.06%), predominantly among girls and mainly in the 1 to 5 year age group. About half of the observed events occurred as a result of accidental ingestion, 27.3% were suicide attempts, and 27.3% arose due to the discontinuation of treatment. Antiepileptic drugs were those most often involved. Three (23%) were serious. The results suggest that children have easy access to medications and are involved in the majority of accidental occurrences. Using drugs involves risks, and drawing attention to such risks while prescribing and dispensing them fosters the sharing of responsibility and the empowerment of the users, measures necessary to health promotion.

Effectiveness of the polysaccharide pneumococcal vaccine among HIV-infected persons in Brazil: a case control study

Abstract Background Polysaccharide pneumococcal vaccine is recommended for use in HIV-infected adults in Brazil but there is uncertainty about its effectiveness in this patient population. The main objective of this study was to assess the effectiveness of the 23-valent polysaccharide pneumococcal vaccine against invasive pneumococcal infection among HIV-infected adult patients in São Paulo, Brazil. Methods A case-control study of 79 cases and 242 controls matched on CD4+ cell count and health care setting was conducted. Among HIV-infected adults in São Paulo, Brazil, with and without S. pneumoniae recovered from a normally sterile site; prior receipt of 23 valent polysaccharide pneumococcal vaccine was determined by review of medical records and patient interview. Results After adjustment for confounding factors, the point estimate for the effectiveness of 23 valent polysaccharide vaccine among HIV-infected adults against all invasive pneumococcal infection was 18% (95% CI: <0 to 62%). Conclusion We were unable to demonstrate a statistically significant protective effect of 23 valent polysaccharide against invasive pneumococcal infection vaccine among HIV-infected adults in Brazil. While the vaccine is relatively inexpensive and safe, its effectiveness among HIV-infected adults in Brazil is uncertain.
