Accidents by external causes in adolescents: care in sentinel urgency and emergency services in the Brazilian State Capitals-2009

Adolescents are seeking new references and experiences, which may involve attitudes of risk and exposure to accidents and violence from external causes. These events constitute a serious Public Health problem. The scope of this study was to analyze the occurrence of accidents by external causes in adolescents from 10 to 19 years of age attended at sentinel urgency and emergency services in Brazil. Data from the 2009 Surveillance System for Violence and Accidents (VIVA 2009) was analyzed in 74 emergency units in 23 state capitals and the Federal District. The findings revealed that 6,434 adolescents (89.8%) were victims of accidents and 730 (10.2 %) were victims of violence. The main causes of the accidents were falls and traffic accidents, and assaults were predominant in violence. For both accidents and violence, non-white male adolescents were predominant and the events occurred most frequently on the public highways. A marked increase was detected, with hospitalization of victims of violence between 15 and 19 years of age. Understanding the epidemiological reality of external causes among adolescents represents an important tool for health prevention and promotion policies and the culture of peace seeking to reduce morbidity and mortality.

Are biological species and higher-ranking categories real? Fish folk taxonomy on Brazil`s Atlantic Forest coast and in the Amazon

Analysis of Brazilian fishers` classifications of 24 marine (Atlantic coast) and 24 freshwater (Amazon) fish species reveals that fishers from the Atlantic coast identify fish mainly through generic names (primary lexemes), while riverine Amazonian fishers typically identify them through binomials. The similarity of Amazonian fish species seems to contribute to the detailed folk taxonomy used by riverine fishers. High-ranking groups called ""relatives"" or ""cousins"" are sorted by fishers in terms of similarities of habitat, diet, and morphology and, secondarily, behavior. The general correspondence between the folk and scientific taxonomies reinforces the reality of both the supracategories used by these fishers and the biological groups as discontinuities in nature. Given the urgency of biological inventories and the lack of knowledge of high-biodiversity environments such as the Atlantic Forest and the Amazon, these results suggest that fisher knowledge and experience could contribute to scientific research.

The Effects of Oxybutynin on Urinary Symptoms in Children with Williams-Beuren Syndrome

Purpose: Williams-Beuren syndrome is a genomic disorder caused by a hemizygous contiguous gene deletion on chromosome 7q11.23. Lower urinary tract symptoms are common in children with Williams-Beuren syndrome. However, there are few data on the management of voiding symptoms in this population. We report our experience using oxybutynin to treat urinary symptoms in children with Williams-Beuren syndrome. Materials and Methods: We prospectively analyzed 42 patients with Williams-Beuren syndrome and significant lower urinary tract symptoms due to detrusor overactivity diagnosed on urodynamics in a 12-week, open-label study. Urological assessment included symptomatic evaluation, the impact of lower urinary tract symptoms on quality of life, frequency-volume chart, urodynamics and urinary tract sonography. After 12 weeks of treatment with 0.6 mg/kg oxybutynin per day given in 3 daily doses, patients were assessed for treatment efficacy and side effects. Results: A total of 17 girls and 19 boys completed medical therapy and were assessed at 12 weeks. Mean +/- SD patient age was 9.2 +/- 4.3 years (range 3 to 18). The most common urinary complaint was urgency, which occurred in 31 patients (86.1%), followed by urge incontinence, which was seen in 29 (80.5%). Compared to baseline, urinary symptoms were substantially improved. The negative impact of storage symptoms on quality of life was significantly decreased from a mean +/- SD of 3.3 +/- 1.7 to 0.5 +/- 0.9 (p <0.001). Mean +/- SD maximum urinary flow improved from 14.2 +/- 15.0 to 20.5 +/- 6.4 ml per second (p <0.001). Conclusions: A total of 12 weeks of therapy with 0.6 mg/kg oxybutynin daily resulted in improvement of lower urinary tract symptoms, quality of life and maximum flow rate in most patients with Williams-Beuren syndrome.

Batrachochytrium dendrobatidis in amphibians confiscated from illegal wildlife trade and used in an ex situ breeding program in Brazil

This paper describes an outbreak of chytridiomycosis affecting a group of Dendrobates tinctorius, a Neotropical anuran species, confiscated from the illegal wildlife trade and housed in a private zoo in Brazil as part of an ex situ breeding program. We examined histological sections of the skin of 30 D. tinctorius and 20 Adelphobates galactonotus individuals. Twenty D. tinctorius (66.7%) and none of the A. galactonotus were positive for Batrachochytrium dendrobatidis (Bd). Multiple development stages of Bd infection were observed. The reasons for the interspecific difference in the rate of infection could not be determined, and further studies are advised. Because the examined population consisted of confiscated frogs, detailed epidemiological aspects could not be investigated, and the source of the fungus remains uncertain. The existence of ex situ amphibian populations is important for protecting species at higher risk in the wild, and ex situ amphibian conservation and breeding programs in Brazil may be established using confiscated frogs as founders. However, this paper alerts these programs to the urgency of strict quarantine procedures to prevent the introduction of potential pathogens, particularly Bd, into ex situ conservation programs.

Acidentes e violência na infância: evidências do inquérito sobre atendimentos de emergência por causas externas - Brasil, 2009

Compreender as características e a magnitude das causas externas (acidentes e violência) em crianças de 0 a 9 anos de idade torna-se cada vez mais importante em Saúde Pública. O objetivo do presente artigo foi analisar os atendimentos de emergência por causas externas em crianças. Utilizaram-se dados do Sistema de Vigilância de Violências e Acidentes em Serviços Sentinelas de Urgência e Emergência (Inquérito VIVA), realizado em 74 serviços de urgência do Distrito Federal e 23 capitais no ano 2009. Analisaram-se dados de 7.123 crianças: 6.897 (96,7%) vítimas de acidentes e 226 (3,3%) de violência. Em comparação às vítimas de violência, os atendimentos por acidentes foram mais frequentes entre crianças de 2 a 5 anos, de pele branca e ocorridos no domicílio (p < 0,05). Dentre os acidentes, as quedas e queimaduras predominaram no grupo de 0 a 1 ano, enquanto os acidentes de transporte foram mais frequentes no grupo de 6 a 9 anos (p < 0,001). Quanto às violências, atendimentos por negligência e agressão física predominaram, respectivamente, nos grupos extremos de faixa etária, sendo um familiar identificado como agressor (p < 0,001). Informações sobre ocorrência de causas externas em crianças podem apoiar políticas de promoção da saúde, além de orientar profissionais de saúde, educadores e famílias na prevenção destas causas.

Causas externas em adolescentes: atendimentos em serviços sentinelas de urgência e emergência nas Capitais Brasileiras - 2009

Os adolescentes estão em busca de novas referências e experiências, o que pode implicar atitudes de risco e exposição às causas externas - acidentes e violências. Estes eventos constituem um grave problema em Saúde Pública. O objetivo deste estudo foi analisar as ocorrências de causas externas em adolescentes de 10 a 19 anos atendidos em serviços sentinela de urgência e emergência no Brasil. Foram analisados dados do inquérito da Vigilância de Violências e Acidentes (Inquérito VIVA 2009) em 74 Unidades de Emergência em 23 capitais e no Distrito Federal. Os achados mostraram que 6.434 (89,8%) adolescentes foram vítimas de acidentes e 730 (10,2 %) de violências. As principais causas de acidentes foram as quedas, outros acidentes e o trânsito e entre as violências predominaram as agressões. Tanto para acidentes como para violências os adolescentes do sexo masculino e a raça/cor não branca foram predominantes; as ocorrências foram mais frequentes na via pública. A alta foi a evolução mais frequente, com maior ocorrência de internação hospitalar nas vítimas de violências entre 15 a 19 anos. Conhecer a realidade epidemiológica das causas externas entre os adolescentes representa uma importante ferramenta para as políticas de prevenção, promoção à saúde e da cultura de paz, visando à redução da morbimortalidade.
