Tratamento ortodôntico oportuno, evitando traçäo cirúrgica de caninos superiores ectópicos: caso clínico / Timely orthodontic treatment, avoiding surgical traction of ectopic upper canines: clinical case

Clinicamente temos observado considerável tendência à mesializaçäo dos caninos superiores. O presente trabalho tem como objetivo alertar o profissional para tratamento ortodôntico evitando traçäo cirúrgica de caninos superiores, através da utilizaçäo de diagnóstico precoce de impactaçäo dos mesmos. De um modo geral, o que se observa é que as condutas odontológicas näo previnem a irrupçäo ectópica dos caninos permanentes. Talvez o motivo principal seja o fato desse dente ser um dos últimos a irromperem na cavidade bucal. Devemos, portanto, utilizar o recurso do diagnóstico precoce e respectivas condutas preventivas

[Dengue study in a slum area in Rio de Janeiro: preliminary analysis]. / Estudo do dengue em área urbana favelizada do Rio de Janeiro: considerações iniciais.

This study is part of a program to control and prevent dengue in a slum bordering on the grounds of the Oswaldo Cruz Foundation in Rio de Janeiro, Brazil. The results obtained from a questionnaire and entomological survey called attention to problems pertaining to the information transmitted by public health campaigns and its interpretation, since many practices result from misunderstanding or forgetting preventive messages. Dengue-related data include most frequent vector breeding sites, people's knowledge, and dengue-related habits. The study's conclusions in terms of dengue prevention point to the need for drafting messages not only about ideal preventive practices but also teaching possible solutions: disseminating frequent messages throughout the year and not only seasonally and planning health education to join health professionals and the population in the search for sustainable dengue control alternatives.

[Hemodynamic and prognostic evaluation of total anomalous pulmonary venous return by means of echocardiographic measurement of the heart cavities]. / Valoración hemodinámica y pronóstica de la conexión anómala total de venas pulmonares mediante medición ecocardiográfica de las cavidades cardiacas.

The purpose was to demonstrate the relationship between cardiac cavity size, measured by echocardiography, with the hemodynamic overload and short-term prognosis in children with total anomalous pulmonary venous return (TAPVR). Ten children were studied; the age varied from 2 weeks to 4 months. The clinical and cardiac catheterization findings were compared with echocardiographic measurements. Children with a smaller left atrium showed severe pulmonary resistance and lower systemic cardiac output (P less than 0.01). Right ventricular dilatation was bigger when pulmonary resistance was more elevated (P less than 0.05). Children with end-diastolic diameter of the left ventricle less than 12.8 mm had lower cardiac output (P less than 0.01) and death rate was significantly elevated during the first twenty weeks of life (80%). Doppler-echocardiography is useful in the recognition of TAPVR type, as well as to evaluate the hemodynamic changes and detect the high risk group.
