Three different school-based sex education and citizenship programs in public schools in Rio de Janeiro, Belo Horizonte, and Salvador, Brazil, were evaluated in a cross-sectional study comparing knowledge, attitudes, and practices in sexuality, citizenship, and gender issues among adolescents participating in the programs' activities as compared to adolescents enrolled in schools without such programs (controls). Results showed that Salvador's program achieved good results, with significant changes in knowledge on sexuality and reproductive physiology, attitudes regarding citizenship, and current use of modern contraceptives; Rio de Janeiro's program succeeded in improving students' knowledge of reproductive physiology and attitudes towards sexuality; Belo Horizonte's participants showed greater knowledge of reproductive physiology and STI/HIV prevention but had less positive attitudes towards gender issues, while reporting greater sexual activity. The main difference between Salvador's program and the others was the focus on creative and cultural activities; Belo Horizonte's main difference was its lack of interaction with health services and professionals. However, after the evaluation Belo Horizonte reframed its educational strategies and launched a scaling-up process in a joint effort with the health and school systems.

Este artigo descreve o primeiro ano de atividades do Centro de Informação sobre Medicamentos da Universidade Federal do Ceará, em Fortaleza, Brasil. O CIM faz parte do GPUIM (Grupo de Prevenção ao Uso Indevido de Medicamentos, do Departamento de Farmácia), sendo operacionalizado por farmacêuticos especializados. O serviço atende à comunidade em geral e aos profissionais da saúde em particular. De dezembro de 1994 a novembro de 1995, 246 pessoas telefonaram ao CIM-UFC, das quais 39% eram usuários de medicamentos, 32% farmacêuticos, 17% parentes e/ou amigos dos usuários, 4,5% estudantes de Farmácia e/ou de Medicina, 4% médicos, 0,8% enfermeiras e 2,8% outros. Os temas mais abordados foram Reações Adversas (28%) Indicações (28%) e Eficácia (18%), sendo os grupos de fármacos mais freqüentes: Vitaminas, Analgésicos e Agentes Antiinflamatórios. O número de solicitações vem aumentando regularmente, variando com a divulgação do serviço através da mídia local e de publicações específicas. Nesse período, o Centro vem esboçando o perfil de um serviço que pode preencher lacunas importantes não só do Sistema de Saúde, como também da formação e prática de médicos e farmacêuticos. Além disso, o Centro está se firmando como uma fonte segura de informações auxiliares nas decisões das pessoas leigas no que diz respeito à automedicação.

Objective:: To present the result of upgrading a clinical gamma-camera to be used to obtain in vivo tomographic images of small animal organs, and its application to register cardiac, renal and neurological images., Methods:: An updated version of the miniSPECT upgrading device was built, which is composed of mechanical, electronic and software subsystems. The device was attached to a Discovery VH (General Electric Healthcare) gamma-camera, which was retired from the clinical service and installed at the Centro de Imagem Pré-Clínica of the Hospital Israelita Albert Einstein. The combined system was characterized, determining operational parameters, such as spatial resolution, magnification, maximum acceptable target size, number of projections, and acquisition and reconstruction times., Results:: Images were obtained with 0.5mm spatial resolution, with acquisition and reconstruction times between 30 and 45 minutes, using iterative reconstruction with 10 to 20 iterations and 4 projection subsets. The system was validated acquiring in vivo tomographic images of the heart, kidneys and brain of normal animals (mice and adult rats), using the radiopharmaceuticals technetium-labeled hexakis-2-methoxy-isobutyl isonitrile (99mTc-Sestamibi), technetium-labeled dimercaptosuccinic acid (99mTc-DMSA) and technetium-labeled hexamethyl propyleneamine oxime (99mTc-HMPAO)., Conclusion:: This kind of application, which consists in the adaptation for an alternative objective of already existing instrumentation, resulted in a low-cost infrastructure option, allowing to carry out large scale in vivo studies with enhanced quality in several areas, such as neurology, nephrology, cardiology, among others., Objetivo:: Apresentar o resultado da adaptação de uma gama câmara clínica para uso dedicado na obtenção de imagens tomográficas in vivo de órgãos de pequenos animais de experimentação, e de sua aplicação na obtenção de imagens cardíacas, renais e neurológicas., Métodos:: Foi construída uma versão atualizada do dispositivo de adaptação miniSPECT, composto por três subsistemas: mecânico, eletrônico e de software. O dispositivo foi montado em uma câmara Discovery VH da General Electric Healthcare, retirada do serviço clínico e instalada no Centro de Imagem Pré-Clínica do Hospital Israelita Albert Einstein. O sistema combinado foi caracterizado, determinando parâmetros de funcionamento como resolução espacial, magnificação, limites de tamanho dos alvos de estudo, número de projeções, tempo de registro e tempo de reconstrução das imagens tomográficas., Resultados:: Foram obtidas imagens com resolução espacial de até 0,5mm, com tempos de registro e reconstrução de 30 a 45 minutos, utilizando reconstrução iterativa com 10 a 20 iterações e 4 subconjuntos de projeções. O sistema foi validado obtendo imagens tomográficas in vivo do coração, dos rins e do cérebro de animais normais (camundongos e ratos adultos), utilizando os radiofármacos hexaquis-2-metoxi-isobutil-isonitrila marcado com 99mTc (Sestamibi-99mTc), ácido dimercaptosuccínico marcado com 99mTc (DMSA-99mTc) e hexametil-propileno-amina-oxima marcada com 99mTc (HMPAO-99mTc)., Conclusão:: Este tipo de aplicação, que consiste na adaptação para um objetivo alternativo de instrumentação já existente, constituiu-se em uma opção de infraestrutura de baixo custo, que permite realizar estudos in vivo em larga escala, com qualidade aprimorada, em áreas diversas, como neurologia, nefrologia, cardiologia, entre outras., Competing Interests: none.

Objective: To describe the Single Photon Emission Microscope (SPEM), a state-of-the-art instrument for small animal SPECT imaging, and characterize its performance presenting typical images of different animal organs., Methods: SPEM consists of two independent imaging devices based on high resolution scintillators, high sensitivity and resolution Electron-Multiplying CCDs and multi-pinhole collimators. During image acquisition, the mouse is placed in a rotational vertical holder between the imaging devices. Subsequently, an appropriate software tool based on the Maximum Likelihood algorithm iteratively produces the volumetric image. Radiopharmaceuticals for imaging kidneys, heart, thyroid and brain were used. The mice were injected with 74 to 148 MBq/0,3mL and scanned for 40 to 80 minutes, 30 to 60 minutes afterwards. During this procedure, the animals remained under ketamine/xilazine anesthesia., Results: SPEM images of different mouse organs are presented, attesting the imaging capabilities of the instrument., Conclusion: SPEM is an innovative technology for small animal SPECT imaging providing high resolution images with appropriate sensitivity for pre-clinical research. Its use with appropriate radiotracers will allow translational investigation of several animal models of human diseases, their pharmacological treatment and the development of potential new therapeutic agents., Competing Interests: none.

This paper describes the first year experience of a Drug Information Center directed to the community, and managed by pharmacysts and pharmacy students from the Department of Pharmacy-UFC, in Fortaleza, Brazil. This pioneer experience recieves technical assistance from the "Centro Regionali di Informazione sul Farmaco-CRIF (Mario Negri Institute Milan-Italy). Those who consult us are registered on a codified formullary while individual information, questions and prepared answers are introduced on a database. From December 1994 to November 1995, 246 persons telephoned CIM-UFC for drug information of which 39% were medicine users, 32% pharmacysts, 17% patients relatives, 4,5% health students, 4% doctors, 0,8% nurses and 2,8% others. The principal questions were related to Adverse Reactions (28%) Indications (28%) and Efficacy (18%). The ATC 2nd level groups most referred to were vitamins, analgesics and antiinflammatory agents. The most frequent problems justifying drug use were classified as: Endocrine, nutritional and metabolic diseases and immunity disorders; Symptoms, signs and ill defined conditions; Infectious and parasitic diseases. Requests are increasing regularly, responding to the mass media campaigns related to drugs and active information is provided by bulletins.
