Comparison of Herbarium Label Data and Published Medicinal Use: Herbaria as an Underutilized Source of Ethnobotanical Information.

The use of herbarium specimens as vouchers to support ethnobotanical surveys is well established. However, herbaria may be underutilized resources for ethnobotanical research that depends on the analysis of large datasets compiled across multiple sites. Here, we compare two medicinal use datasets, one sourced from published papers and the other from online herbaria to determine whether herbarium and published data are comparable and to what extent herbarium specimens add new data and fill gaps in our knowledge of geographical extent of plant use. Using Brazilian legumes as a case study, we compiled 1400 use reports from 105 publications and 15 Brazilian herbaria. Of the 319 species in 107 genera with cited medicinal uses, 165 (51%) were recorded only in the literature and 55 (17%) only on herbarium labels. Mode of application, plant part used, or therapeutic use was less often documented by herbarium specimen labels (17% with information) than publications (70%). However, medicinal use of 21 of the 128 species known from only one report in the literature was substantiated from independently collected herbarium specimens, and 58 new therapeutic applications, 25 new plant parts, and 16 new modes of application were added for species known from the literature. Thus, when literature reports are few or information-poor, herbarium data can both validate and augment these reports. Herbarium data can also provide insights into the history and geographical extent of use that are not captured in publications.

Quality of hand hygiene in a pediatric hospital in Rio de Janeiro, Brazil.

We assessed the quality of hand hygiene among healthcare workers at a pediatrics hospital in Rio de Janeiro, Brazil. Hand hygiene was performed in 491 (34%) of 1,455 opportunities. Of these hand hygiene events, correct performance was observed in only 173 (35%). Multivariate analysis revealed that correct performance of hand hygiene was associated with the use of an alcohol-based product and a lack of jewelry (for all events) and employment in an infirmary with a comparatively higher ratio of nurses to patients (for events involving nurses).

Comparison of palpebral fissure obliquity in three different racial groups.

PURPOSE: To compare the obliquity of the palpebral fissures of three different racial populations. METHODS: Prospective observational study. Frontal views of the palpebral fissures of three different groups of subjects (Brazilian whites, Brazilian Japanese, and Brazilian Indians from the Upper Rio Negro Basin of the Amazonas State) were acquired with a photographic camera and transferred to a Macintosh computer. Using the National Institutes of Health Image software (NIH Image), the angle formed by the inner and the outer canthi was measured for all images. RESULTS: The mean fissure angle of the Japanese (9.39 degrees) was not statistically different from the mean angle of the Indians (9.64 degrees). On the other hand, both were significantly greater than the mean angle of the whites (4.60 degrees). CONCLUSIONS: Marked fissure obliquity is found more frequently among Asians than among whites.

[The first São Paulo meeting on mental health services for college students]. / O I encontro paulista dos serviços de assistência psicológica ao estudante universitário.

The authors initially describe the main psychological problems observed among medical students. After that, they write briefly about the history of the psychological support to the college student in Brazil. Next, they present a summary of the First São Paulo Meeting on Mental Health Services for College Students. Finally, they point out the main topics presented in the meeting, like the identity of the Service, its specificity, its institutional role, the ideal working setting and its ethical questions. Current working conditions for medical professionals and some characteristics of Contemporary Medicine were also discussed.
