The impact of the medical speciality in primary health-care problem solving in Belo Horizonte, Brazil: homeopaths versus family doctors: a preliminary quantitative study

Introduction: This research project examined influence of the doctors' speciality on primary health care (PHC) problem solving in Belo Horizonte (BH) Brazil, comparing homeopathic with family health doctors (FH), from the management's and the patients' viewpoint. In BH, both FH and homeopathic doctors work in PHC. The index of resolvability (IR) is used to compare resolution of problems by doctors. Methods: The present research compared IR, using official data from the Secretariat of Health and test requests made by the doctors and 482 structured interviews with patients. A total of 217,963 consultations by 14 homeopaths and 67 FH doctors between 1 July 2006 and 30 June 2007 were analysed. Results: The results show significant differences greater problem resolution by homeopaths compared to FH doctors. Conclusion: In BH, the medical speciality, homeopathy or FH, has an impact on problem solving, both from the managers' and the patients' point of view. Homeopaths request fewer tests and have better IR compared with FH doctors. Specialisation in homeopathy is an independent positive factor in problem solving at PHC level in BH, Brazil.

Women's knowledge of health effects of oral contraceptives in five Brazilian cities

Background: Although acceptability of combined oral contraceptives (COCs) is widespread, patients are often unaware of the noncontraceptive benefits. Study Design: An opinion survey through telephone interview was conducted to evaluate the knowledge of 500 Brazilian women 15-45 years of age who were current users or had recently used COCs. Data were obtained on their knowledge of adverse events, the effects of COCs on health- and menstrual-related symptoms, noncontraceptive benefits and aspects related to sexual response. Results: Most of the women interviewed learned about the pill from doctors or the Internet. Other than the pill, the best-known contraceptive methods were the condom and intrauterine device. The majority of women believe that COCs do not change the risk of gynecological cancers. Most believed that they had no significant effect on sexual response. Conclusions: COCs users in Brazil lack precise information on aspects related to general health, particularly menstrual-related symptoms and noncontraceptive health benefits. (C) 2012 Elsevier Inc.

What do medical students think about their quality of life? A qualitative study

Background: Medical education can affect medical students' physical and mental health as well as their quality of life. The aim of this study was to assess medical students' perceptions of their quality of life and its relationship with medical education. Methods: First-to sixth-year students from six Brazilian medical schools were interviewed using focus groups to explore what medical student's lives are like, factors related to increases and decreases of their quality of life during medical school, and how they deal with the difficulties in their training. Results: Students reported a variety of difficulties and crises during medical school. Factors that were reported to decrease their quality of life included competition, unprepared teachers, excessive activities, and medical school schedules that demanded exclusive dedication. Contact with pain, death and suffering and harsh social realities influence their quality of life, as well as frustrations with the program and insecurity regarding their professional future. The scarcity of time for studying, leisure activities, relationships, and rest was considered the main factor of influence. Among factors that increase quality of life are good teachers, classes with good didactic approaches, active learning methodologies, contact with patients, and efficient time management. Students also reported that meaningful relationships with family members, friends, or teachers increase their quality of life. Conclusion: Quality of teachers, curricula, healthy lifestyles related to eating habits, sleep, and physical activity modify medical students' quality of life. Lack of time due to medical school obligations was a major impact factor. Students affirm their quality of life is influenced by their medical school experiences, but they also reframe their difficulties, herein represented by their poor quality of life, understood as necessary and inherent to the process of becoming doctors.

Bioethical Aspects Across Medicine: The Care of Cardiovascular Diseases in Brazil

Bioethics applied to medicine extrapolates the traditional medical concepts of non-maleficence (primum non nocere) and beneficence (bonum facere) and regards to justice, autonomy, equity, protection, compassion and humanization, not considering people just like patients, but understanding the complex existence of each single person. Worldwide, the morbidity and mortality indices regarding to diseases of heart and blood vessels became progressively grater. For countries in development, like Brazil, these numbers are even more expressive and this increase trend seems to be caused by wider exposition of population to some risk factors. This article broaches an intersection between bioethics and medicine, focusing the reality of cardiovascular diseases in Brazil and the necessity of doctors to base their behavior in bioethical paradigms.

Obstructive acute abdomen due to intestinal intussusception in adolescent

Introduction: Intestinal intussusception is a rare disease out of childhood. It is represented by an invagination of a bowel into the lumen of the adjacent segment. Case Report: This article reports a case of 14 year-old patient presenting intestinal obstruction caused by an intussusception at the level of the terminal ileum. A surgical resection of the invaginated segment was done and the histopathological study disclosed no evidence of malignancy. Discussion: In children, it is usually idiopathic, but among adolescents and adults it is often related to anatomic lesions, some of them neoplastic with high risk of malignancy. Preoperative diagnosis of intestinal intussusception is difficult due to its nonspecific and subacute symptoms. Computed tomography and ultrassonography can confirm the intussusception through characteristic images. Conclusion: Intestinal intussusception in adolescents is a rare and often misdiagnosed disease, deserving special attention from surgeons and general doctors.

Post-trial access to study medication: a Brazilian e-survey with major stakeholders in clinical research

Objectives To analyse the perspective of clinical research stakeholders concerning post-trial access to study medication. Methods Questionnaires and informed consents were sent through e-mail to 599 ethics committee (EC) members, 290 clinical investigators (HIV/AIDS and Diabetes) and 53 sponsors in Brazil. Investigators were also asked to submit the questionnaire to their research patients. Two reminders were sent to participants. Results The response rate was 21%, 20% and 45% in EC, investigators and sponsors' groups, respectively. 54 patients answered the questionnaire through their doctors. The least informative item in the consent form was how to obtain the study medication after trial. If a benefit were demonstrated in the study, 60% of research participants and 35% of EC answered that all patients should continue receiving study medication after trial; 43% of investigators believed the medication should be given to participants, and 40% to subjects who participated and benefited from treatment. For 50% of the sponsors, study medication should be assured to participants who had benefited from treatment. The majority of responders answered that medication should be provided free by sponsors; investigators and sponsors believed the medication should be kept until available in the public health sector; EC members said that the patient should keep the benefit; patients answered that benefits should be assured for life. Conclusions Due to the study limitations, the results cannot be generalised; however, the data can contribute to discussion of this complex topic through analysing the views of stakeholders in clinical research in Brazil.

Dyslipidemia: evidence of efficacy of the pharmacological and non-pharmacological treatment in the elderly

The clinical decision to control risk factors for cardiovascular disease (CVD) in the elderly takes the followings into consideration: (1) the elderly life expectancy; (2) the elderly biological age and functional capacity; (3) the role of cardiovascular disease in the elderly group; (4) the prevalence of risk factors in the elderly; and (5) The effectiveness of treatment of risk factors in the elderly. A large number of studies showed the efficacy of secondary and primary prevention of dyslipidemia in the elderly. However, the only trial that included patients over 80 years was the Heart Protection Study (HPS). Statins are considered the first line therapy for lowering low-density lipoprotein cholesterol (LDL-C). Because lifestyle changes are very difficult to achieve, doctors in general tend to prescribe many drugs to control cardiovascular risk factors. However, healthy food consumption remains a cornerstone in primary and secondary cardiovascular prevention and should be implemented by everyone.

Os "doutores" da federação: formação acadêmica dos senadores brasileiros e variáveis associadas

Fazemos uma descrição detalhada da formação acadêmica dos senadores brasileiros no período de 1987 a 2006, buscando identificar padrões "cross section" e ao longo do tempo. Procuramos também avaliar se as formações estão relacionadas à região de origem, à filiação partidária, à participação nas comissões, à experiência parlamentar e ao comportamento em votações nominais no plenário do Senado. Verificamos que há um predomínio de senadores formados em Direito, mas a sua proporção vem caindo ao longo do tempo. Outros grupos importantes foram os dos engenheiros, dos profissionais da saúde e da área de Humanidades. Destacamos o papel dos senadores formados em Economia, que se concentraram na região Sudeste, nos partidos com vocação presidencial - Partido dos Trabalhadores (PT) e no Partido da Social Democracia Brasileira (PSDB) - e na Comissão de Assuntos Econômicos. Os economistas parecem ter desempenhado um papel importante, em um momento de crises econômicas internas e externas, de inflação galopante e de uma agenda que privilegiava ajustes fiscais, reformas, privatizações e estabilidade macroeconômica.

Brain activity and medical diagnosis: an EEG study

Abstract Background Despite new brain imaging techniques that have improved the study of the underlying processes of human decision-making, to the best of our knowledge, there have been very few studies that have attempted to investigate brain activity during medical diagnostic processing. We investigated brain electroencephalography (EEG) activity associated with diagnostic decision-making in the realm of veterinary medicine using X-rays as a fundamental auxiliary test. EEG signals were analysed using Principal Components (PCA) and Logistic Regression Analysis Results The principal component analysis revealed three patterns that accounted for 85% of the total variance in the EEG activity recorded while veterinary doctors read a clinical history, examined an X-ray image pertinent to a medical case, and selected among alternative diagnostic hypotheses. Two of these patterns are proposed to be associated with visual processing and the executive control of the task. The other two patterns are proposed to be related to the reasoning process that occurs during diagnostic decision-making. Conclusions PCA analysis was successful in disclosing the different patterns of brain activity associated with hypothesis triggering and handling (pattern P1); identification uncertainty and prevalence assessment (pattern P3), and hypothesis plausibility calculation (pattern P2); Logistic regression analysis was successful in disclosing the brain activity associated with clinical reasoning success, and together with regression analysis showed that clinical practice reorganizes the neural circuits supporting clinical reasoning.

O ATO MÉDICO NO CRIME DE TORTURA

A presente pesquisa verificou se a legislação surgida após a Segunda Guerra Mundial foi apta a inibir o comportamento maleficente de médicos no auxílio em especializar, dissimular e acobertar a tortura. Foi demonstrado o envolvimento médico com experimentos em seres humanos durante a Segunda Guerra Mundial e corroborou-se que a maleficência médica ainda é usada nos dias de hoje na sociedade contemporânea, permitindo aos profissionais de saúde, desde o período da Guerra Fria, o envolvimento com a tortura e a consequente violação dos princípios da Bioética, especialmente, na conjuntura atualíssima da guerra norte-americana contra o terrorismo. Ao final foram propostas soluções, tendo em vista as noções de Bioética, as normas de Direito Internacional e os Direitos Humanos
