Oral Health Promotion Through an Online Training Program for Medical Students

The objective of this study was to compare the impact on knowledge and counseling skills of face-to-face and Internet-based oral health training programs on medical students. Participants consisted of 148 (82 percent) of the 180 invited students attending their fifth academic year at the Faculty of Medicine, University of Sao Paulo, Brasil, in 2007. The interventions took place during a three-month training period in the clinical Center for Health Promotion, which comprised part of a clerkship in Internal Medicine. The students were divided into four groups: 1) Control Group (Control), with basic intervention; 2) Brochure Group (Br), with basic intervention plus complete brochure with oral health themes; 3) Cybertutor Group (Cy), with basic intervention plus access to an Internet-based training program about oral health themes; and 4) Cybertutor + Contact Group (Cy+C), the same as Cy plus brief proactive contact with a tutor. The impact of these interventions on student knowledge was measured with pre- and post assessments, and student skills in asking and counseling about oral health were assessed with an objective structured clinical examination (OSCE). Multivariate logistic regression models were applied to identify the odds ratios of scoring above Control's medians on the final assessment and the OSCE. In the results, Cy+C performed significantly better than Control on both the final assessment (OR 9.4; 95% CI 2.7-32.8) and the OSCE (OR 5.6; 95% CI 1.9-16.3) and outperformed all the other groups. The Cy+C group showed the most significant increase in knowledge and the best skills in asking and counseling about oral health.

Toxoplasmosis in Indo-Pacific humpbacked dolphins (Sousa chinensis), from Queensland

Objective To describe the clinical signs, gross pathology, serology, bacteriology, histopathology, electron microscopy and immunohistochemistry findings associated with toxoplasmosis in four Indo-Pacific humpbacked dolphins (Sousa chinensis) that stranded in Queensland in 2000 and 2001. Design Clinical assessment, gross necropsy, and laboratory examinations. Procedure Necropsies were performed on four S chinensis to determine cause of death. Laboratory tests including serology, bacteriology, histopathology and transmission electron microscopy were done on the four dolphins. Immunohistochemistry was done on the brain, heart, liver, lung, spleen and adrenal gland from various dolphins to detect Toxoplasma gondii antigens. Results Necropsies showed all of four S chinensis that stranded in Queensland in 2000 and 2001 had evidence of predatory shark attack and three were extremely emaciated. Histopathological examinations showed all four dolphins had toxoplasmosis with tissue cysts resembling T gondii in the brain. Tachyzoite stages of T gondii were detected in the lungs, heart, liver, spleen and adrenal gland, variously of all four dolphins. Electron microscopy studies and immunohistochemistry confirmed the tissues cysts were those of T gondii. All four dolphins also had intercurrent disease including pneumonia, three had peritonitis and one had pancreatitis. Conclusion Four S chinensis necropsied in Queensland in 2000 and 2001 were found to be infected with toxoplasmosis. It is uncertain how these dolphins became infected and further studies are needed to determine how S chinensis acquire toxoplasmosis. All four dolphins stranded after periods of heavy rainfall, and coastal freshwater runoff may be a risk factor for T gondii infection in S chinensis. This disease should be of concern to wildlife managers since S chinensis is a rare species and its numbers appear to be declining.

Riddles of disarmament: Saddam and the Washington sniper

The mythic relationship that both "terrorists" share with American society is powerful. Saddam was armed as an anti-fundamentalist deterrent with Washington cash reserves, with his technologies for mass destruction a predictable by-product. The main Washington sniper comes from a landscape mushroomed with militia and dilettante gun specialists.

Relações públicas e comunicação para a saúde: um projecto para o ACES: estratégia de relações públicas para o agrupamento de centros de saúde do Vale do Sousa Sul

Discute-se no presente trabalho final de Mestrado a ligação entre duas áreas diferentes, quer nos seus princípios, quer nas suas práticas, mas que se complementam: Relações Públicas e Comunicação para a Saúde (não se tratando de comunicação em contextos de saúde). Assim, defende-se, ao longo deste trabalho, a posição de que as Relações Públicas podem ser consideradas uma das principais armas no que diz respeito à prevenção, promoção e educação para a saúde, que se reflecte na melhoria da qualidade de vida dos cidadãos, famílias e comunidades. Pretende-se, assim, desenvolver um projecto de uma estratégia de comunicação onde se demonstra a posição aqui defendida e, por outro lado, um projecto com capacidade para ser implementado no Agrupamento de Centro de Saúde do Vale do Sousa Sul.
