OBJETIVO: Estudar a população de uma casa de custódia quanto a aspectos criminais, diagnóstico clínico e perfil da vítima. MÉTODOS: Foram examinados os prontuários de 269 pacientes durante o ano de 2005. Considerou-se apenas a população do gênero masculino cujos casos já tinham laudo anexado ao prontuário psiquiátrico-criminal. RESULTADOS: Foi encontrado predomínio de transtornos psicóticos (58%). O crime mais freqüente foi contra a vida (52,8%), sendo o grupo dos pacientes psicóticos o que teve maior associação com esse tipo de crime (p < 0,05). Desses crimes, 89,7% resultaram em morte e em 34,5% a vítima era um parente próximo. Os sujeitos com retardo mental cometeram proporcionalmente mais crimes sexuais quando comparados com os pacientes psicóticos e considerando somente crime sexual ou contra a vida (p < 0,05). Em 78,5% dos crimes sexuais as vítimas tinham idade inferior a 14 anos. CONCLUSÃO: A população estudada é semelhante às de outras instituições com o mesmo perfil. Os achados em relação às características das vítimas, tanto nos casos de homicídio pelos psicóticos como nos crimes sexuais dos sujeitos com retardo mental, indicam que aspectos da vítima têm papel importante no crime.

OBJECTIVE The aim of this study was to compare the performance of the current conventional Pap smear with liquid-based cytology (LBC) preparations. STUDY DESIGN Women routinely undergoing their cytopathological and histopathological examinations at Fundação Oncocentro de São Paulo (FOSP) were recruited for LBC. Conventional smears were analyzed from women from other areas of the State of São Paulo with similar sociodemographic characteristics. RESULTS A total of 218,594 cases were analyzed, consisting of 206,999 conventional smears and 11,595 LBC. Among the conventional smears, 3.0% were of unsatisfactory preparation; conversely, unsatisfactory LBC preparations accounted for 0.3%. The ASC-H (atypical squamous cells - cannot exclude high-grade squamous intraepithelial lesion) frequency did not demonstrate any differences between the two methods. In contrast, the incidence of ASC-US (atypical squamous cells of undetermined significance) was almost twice as frequent between LBC and conventional smears, at 2.9 versus 1.6%, respectively. An equal percentage of high-grade squamous intraepithelial lesions were observed for the two methods, but not for low-grade squamous intraepithelial lesions, which were more significantly observed in LBC preparations than in conventional smears (2.2 vs. 0.7%). The index of positivity was importantly enhanced from 3.0% (conventional smears) to 5.7% (LBC). CONCLUSIONS LBC performed better than conventional smears, and we are truly confident that LBC can improve public health strategies aimed at reducing cervical lesions through prevention programs.

OBJETIVO: Avaliar uso de jogos eletrônicos (videogames, jogos de computador e internet) em uma amostra de universitários. MÉTODO: Um questionário a respeito de comportamentos relacionados ao uso de jogos eletrônicos, contendo a escala Problem Videogame Playing (PVP), foi aplicado em 100 alunos da Universidade de São Paulo (USP). RESULTADOS: A maioria (83%) relatou ter jogado no último ano, dentre a qual 81,9% eram homens, 51,8% jogavam de 1 a 2 horas por sessão; 74,4% afirmaram que jogar não interfere em seus relacionamentos sociais e 60,5%, que o uso de jogos violentos não influencia sua agressividade. Os estudantes dividiram-se entre jogadores ocasionais e frequentes, diferenciando-se por duração de cada sessão, jogo preferido, motivação para jogar, e influência do jogo na vida social. Cerca de 5% relataram só parar de jogar quando interrompidos, normalmente jogar mais de 4 horas por sessão e se relacionar mais com amigos virtuais, sugerindo maior envolvimento com a atividade. Na escala PVP, 15,8% da amostra preencheu mais da metade dos itens, indicando consequências adversas associadas ao uso dos jogos eletrônicos. CONCLUSÃO: Observou-se que o uso de jogos eletrônicos é comum entre os estudantes da USP e que uma parcela apresenta problemas relacionados ao excesso de jogo.

OBJETIVO: Verificar como são tratados pacientes com insuficiência cardíaca (IC) em hospital terciário de São Paulo. MÉTODOS: Analisados 100 pacientes com IC, em tratamento ambulatorial, com idade média de 56,8 anos, sendo 76 homens. Todos realizaram estudo ecocardiográfico, que identificou diâmetros ventriculares entre 48 e 89mm (média 65,9) e fração de ejeção (FE) entre 0,22 e 0,59 (média 0,43). A etiologia da disfunção ventricular (DV) foi isquêmica em 42 casos, cardiomiopatia dilatada em 28, secundária à valvopatia em 12, doença de Chagas em 10 e cardiomiopatia hipertensiva em 8. Analisou-se a terapêutica prescrita, se continha inibidores da enzima conversora de angiotensina (IECA) e qual a sua dosagem. Foi analisado, também, se a etiologia ou o grau de DV tinha influência na prescrição. RESULTADOS: Oitenta e sete pacientes receberam IECA, sendo que em 31 a dose foi inferior à preconizada nos grandes estudos. Digoxina foi prescrita em 69 casos, diuréticos em 85 e ácido acetilsalicílico em 33. Dividindo os pacientes em dois grupos, com FE maior e menor que 0,45, observamos que, no último, foi maior a prescrição de IECA (91,5% vs 80,4%) e maior o uso de doses adequadas (61% vs 48,7%). CONCLUSÃO: A maioria dos pacientes foi tratada conforme recomendações atuais, apresentando boa tolerabilidade para IECA, contudo 1/3 deles não usou IECA em dose considerada adequada. Esquemas terapêuticos com betabloqueadores e inibidores da angiotensina II não fizeram parte da prática clínica rotineira.

OBJETIVO: Realizar levantamento de fatores de risco para aterosclerose na população > ou = 20 anos de São José do Rio Preto, e comparar os dados obtidos com os coletados, em levantamento similar, em 1991. MÉDOTOS: Pesquisa quantitativa com amostragem estratificada por sexo e idade. Os entrevistados (646 indivíduos, 303 homens) foram abordados em Postos de Saúde e outros pontos de afluxo da população, distribuídos por zona geográfica e por classe social dos bairros. A margem de erro foi de 4%, e o intervalo de confiança (IC) de 95%. RESULTADOS: A) Níveis médios de HDL-colesterol (apenas em 1997): homens 43,7±15mg/dL, mulheres 49,6±13,5mg/dL (p<0,001, 95% IC 3,7 a 8,1); B) níveis médios de colesterol total em 1991 vs 1997: população global 192,5±48,9mg/dL vs 190,5±42,5mg/dL (p=NS); homens 187,6±53,3 vs 190,5±42,5mg/dL (p=NS); mulheres 196,8±40mg/dL vs 187,6±37,8mg/dL (p=0,008, 95% IC 2,4 a 15,9). C) Em análise de regressão, as variáveis que se correlacionaram significativamente com níveis de colesterol, em ambas as pesquisas, foram: idade (p<0,001), pressão arterial sistólica (p<0,001) e diastólica (p<0,001), dieta (p<0,001). Sexo feminino correlacionou-se apenas em 1991 (p=0,011) e sedentarismo apenas em 1997 (p=0,014). CONCLUSÃO: Os níveis de colesterol na população adulta de São José do Rio Preto são bastante aceitáveis, sendo que no sexo feminino diminuíram, de maneira significativa, na pesquisa atual, em relação à realizada em 1991.

OBJECTIVE: To characterize the risk profile for atherosclerosis (AS) in adolescents and young adults of a private university in São Paulo. METHODS: Clinical, nutritional, and laboratory parameters were evaluated in 209 students of both genders aged 17 to 25 years. In addition to determination of the lipid profile, the association of its abnormal values with other risk factors for AS was also investigated. RESULTS: Increased levels of total cholesterol, LDL-C and triglycerides (TG) were observed in 9.1%, 7.6% and 16.3% of the students, respectively, and decreased levels of HDL-C in 8.6% of them. Prevalence of the remaining risk factors analyzed was elevated: sedentary life style (78.9%); high intake of total fat (77.5%); high cholesterol intake (35.9%); smoking, hypertension (15.8%) and obesity (7.2%). There was an association between elevated LDL-C and TG levels and sedentary life style and body mass index. CONCLUSION: The high prevalence of risk factors for AS in young individuals draws attention to the need for adopting preventive plans.

OBJECTIVE: To analyze in out clinic elderly patients of both sexes for the prevalence of risk factors for atherosclerosis and study their association with the complications of atherosclerosis. METHODS: Five hundred and sixteen outpatients, 152 men and 364 women, 60 years or older, were studied. The prevalences of hypertension, dyslipidemia, diabetes mellitus, cigarette smoking and obesity were determined in both sexes and compared using the chi-square test. The association between these factors and the presence of atherosclerotic complications was analyzed by logistic regression. RESULTS: The comparative analysis of the factors in both sexes showed that hypertension, total cholesterol > or = 240mg/dL, LDL-cholesterol > or = 160mg/dL, and body mass index >27.5 were more frequent among women, but HDL-cholesterol <35mg/dL and cigarette smoking were more frequent among men, and no difference occurred between sexes in relation to the frequency of triglycerides > or = 250mg/dL and diabetes mellitus. After adjustment of the variables in the regression model, we observed that in the total of elderly patients, risk factors for complications of atherosclerosis were: triglycerides > or = 250mg/dL, hypertension, and male sex. Among men, the risk factors were: LDL-cholesterol > or = 160mg/dL, diabetes mellitus, HDL-cholesterol <35mg/dL and hypertension. Among women, the risk factors were: tryglicerides > or = 250mg/dL and hypertension. CONCLUSION: The results showed that, in the elderly, the risk factors for atherosclerosis persist, but with different behaviors between men and women. The study suggests that the relative importance of the risk factors can change with the aging process.

OBJECTIVE: To describe mortality due to cardiovascular diseases in women during the reproductive age (15 to 49 years) in the state of São Paulo, Brazil, from 1991 to 1995. METHODS: A list of all deaths and their underlying causes, coded according to the International Classification of Diseases, 9th revision, multiple causes of death, and estimates of the female population according to age groups were provided by the SEADE Foundation. Specific coefficients for 100 thousand women for each year as well as the medians of these coefficients related to 5 years, and the percentage of death by subgroups were calculated. RESULTS: Cerebrovascular diseases have the highest coefficients (14.24 for 100 thousand females), followed by ischemic heart disease (7.37), other heart diseases (6.39), hypertensive disease (3.03), chronic rheumatic heart disease (1.58), pulmonary vascular diseases (1.29), and active rheumatic fever (0.05). Systemic arterial hypertension, as an associated cause, occurred in 55.3% to 57.8% of all the deaths due to intracerebral hemorrhage and in 30.4% to 30.8% due to subarachnoid hemorrhage. CONCLUSION: The significance of cerebrovascular diseases, coronary artery disease, and systemic arterial hypertension as causes of mortality suggests the need to emphasize preventive actions for young women who have the potential to reproduce to avoid possible complications in future pregnancies, and premature mortality.

OBJECTIVE: To study the prevalence of systemic hypertension and its control in the population of Catanduva, in the state of São Paulo, Brazil. METHODS: We carried out a randomized cross-sectional population-based study of the urban population of Catanduva with individuals above 18 years of age (688 individuals accounting for 0.9% of the referred population). We interviewed study participants to analyze the major qualitative and quantitative variables that could influence the hypertensive scenario and the risk for systemic hypertension. Blood pressure was measured through the indirect method according to the III Consenso Brasileiro de Hipertensão (III Brazilian Consensus on Hypertension), which established blood pressure levels > or = 140/90 mm Hg as hypertensive. RESULTS: The prevalence of systemic hypertension was higher in individuals with: (1) history of hypertension (p<0.0001); (2) diabetes mellitus (p=0.05); (3) body mass index (B. M. I) > or = 25 kg/m² (p<0.001); (4) low educational level (p<0.0001); (5) familial income ranging from 1 to 5 minimum wages (p<0.05); (6) unmarried status (divorced/separated and widow(er)s) (p<0.0001). Of the interviewed individuals, 27.6% (p=0.05) had blood pressure levels under control. CONCLUSION: Our study showed that the prevalence of systemic hypertension was 31.5%, and that 27.6% of the individuals interviewed had blood pressure levels under control at the time of the interview.

[Excerto] 5.1. INTRODUÇÃO As engrenagens de parafuso sem-fim pertencem ao grupo das engrenagens torsas1, em que uma das rodas tem a forma de um parafuso (Branco et al., 2009). As engrenagens de parafuso sem-fim podem também ser consideradas como um caso particular das engrenagens helicoidais cruzadas, sendo que a capacidade de carga é maior no caso do parafuso sem-fim (Flores e Gomes, 2014c). A figura 5.1 ilustra uma engrenagem de parafuso sem-fim com roda helicoidal. Na verdade, esta é uma das formas mais simples e mais frequentemente utilizada na prática corrente e que inclui um parafuso cilíndrico e uma roda cilíndrica de dentes helicoidais, daí a designação de parafuso sem-fim roda helicoidal (Niemann, 1971; Drago, 1988). Na grande maioria das aplicações de parafusos sem-fim o ângulo formado pelos eixos do parafuso e da roda é igual a 90º. As engrenagens de parafuso sem-fim não são, em geral, reversíveis, isto é, funcionam apenas quando o veio motor aciona o parafuso sem-fim, uma vez que quando o sistema é acionado pela roda, a engrenagem tende a bloquear2 (Henriot, 1979; Shigley e Uicker, 1980).

OBJECTIVE: To study the seasonal variation in mortality due to myocardial infarction in the city of São Paulo. METHODS: We analyzed the database of PROAIM (Programa de Aprimoramento de Informações de Mortalidade) containing the registrations of the certificates of deaths due to myocardial infarction (International Classification of Diseases, 10th edition, classification I21) of the residents of the municipality of São Paulo during 12 months (from December 1996 to November 1997). The number of deaths was corrected for a standard period of 90 days and then it was divided by the corresponding population to obtain the event rate per 10 thousand inhabitants. The magnitude of the seasonal variation, which was defined by the difference of the relative risks between the seasons with higher and lower mortality, was estimated. RESULTS: A total of 5,615 deaths due to myocardial infarction were included in the study. Sixty-one per cent occurred in the male sex, and the mean age was 68 years. The mortality rate during winter was always higher and that during summer was lower than that during the other seasons (P<0.01), independent from age and sex. Seasonal variations in deaths due to myocardial infarction was 30% in the general group, being 23% in individuals who died younger than 75 years, and 44% in the older ones. CONCLUSION: A marked seasonal variation in mortality due to myocardial infarction was observed in the city of São Paulo, with a significant increase in its magnitude and age distribution during the winter, similar to those reported in regions of North America and Europe with temperate climates.

OBJECTIVE: To assess whether a difference exists in coronary heart disease clinical manifestations and the prevalence of risk factors between Japanese immigrants and their descendents in the city of São Paulo. METHODS: Retrospective analysis of coronary artery disease clinical manifestations and the prevalence of risk factors, comparing 128 Japanese immigrants (Japanese group) with 304 Japanese descendents (Nisei group). RESULTS: The initial manifestation of the disease was earlier in the Nisei group (mean = 53 years), a difference of 12 years when compared with that in the Japanese group (mean = 65 years) (P<0.001). Myocardial infarction was the first manifestation in both groups (P = 0.83). The following parameters were independently associated with early coronary events: smoking (OR = 2.25; 95% CI = 1.35-3.77; P<0.002); Nisei group (OR = 10.22; 95% CI = 5.64-18.5; P<0.001); and female sex (OR = 5.04; 95% CI = 2.66-9.52; P<0.001). CONCLUSION: The clinical presentation of coronary heart disease in the Japanese and their descendents in the city of São Paulo was similar, but coronary heart disease onset occurred approximately 12 years earlier in the Nisei group than in the Japanese group.

OBJECTIVE: To assess the clinical and demographic characteristics of a population with ischemic heart disease admitted in the final decades of the 20th century. METHODS: This study retrospectively assessed patients hospitalized with ischemic heart disease divided into the following 2 groups: acute group - 11.181 patients with acute myocardial infarction admitted from 1/1/82 to 12/31/94; and chronic group - 4.166 patients undergoing coronary artery bypass graft surgery from 1/1/84 to 12/31/94. RESULTS: In the acute group, an increase in the percentage of females (from 22.7% to 27.7%, P<0.001) and diabetic individuals (from 12.4% to 17.5%, P<0.001) was observed, as was an increase in age (from 57.4±11.5 to 59.9±12.1 years, P<0.05). In-hospital mortality was greater among females (27.8% and 15.7%, P=0.001), among diabetic individuals (24.2% and 17.8%, P=0.001), and among the elderly (60.9±15.2 and 57.7±11.8 years, P=0.0001). In the chronic group, an increase in the percentage of females (from 17.5% to 27.2%, P=0.001) was observed, as was an increase in age (from 56.3±8.6 to 60.5±9.6 years, P=0.0001). In-hospital mortality was greater among females (8.3% and 5.8%, P<0.05) and among the elderly (58.1±9.1 and 62.1±7.9 years, P=0.0001). CONCLUSION: The characteristics of the population studied with ischemic heart disease point towards a worse prognosis, due to the greater percentages of females, older patients, and diabetic patients, groups known to have greater in-hospital mortality.

OBJETIVO: Identificar os fatores de risco, associados com infarto agudo do miocárdio (IAM), com as respectivas forças de associação, na região metropolitana de São Paulo. MÉTODOS: Os casos eram pacientes com diagnóstico de primeiro IAM com elevação do segmento ST e os controles eram indivíduos sem doença cardiovascular conhecida. Foram incluídos 271 casos e 282 controles provenientes de 12 hospitais. Os fatores avaliados: raça, escolaridade, estado civil, renda familiar, história familiar de insuficiência coronariana, antecedentes de hipertensão arterial e de diabetes mellitus, reposição hormonal em mulheres, tabagismo, atividade física, consumo de álcool, colesterol total, LDL-colesterol, HDL-colesterol, triglicérides e glicose, índice de massa corporal e relação cintura-quadril. RESULTADOS: Os seguintes fatores de risco apresentaram associação independente com IAM: tabagismo (razão de chances [OR]=5,86; intervalo de confiança [IC] 95% 3,25-10,57; p<0,00001), relação cintura-quadril [tercil superior vs. inferior] (OR=4,27; IC 95% 2,28-8,00; p<0,00001), antecedentes de hipertensão arterial (OR=3,26; IC 95% 1,95-5,46; p<0,00001), relação cintura-quadril [tercil intermediário vs. inferior] (OR=3,07; IC95% 1,66-5,66; p=0,0003), nível sérico de LDL-colesterol (OR=2,75; IC 95% 1,45-5,19; p=0,0018), antecedentes de diabetes mellitus (OR=2,51; IC 95% 1,45-5,19; p=0,023), história familiar de insuficiência coronariana (OR=2,33; IC 95% 1,44-3,75; p=0,0005) e HDL-colesterol (OR=0,53; IC 95% 0,32-0,87; p=0,011). CONCLUSÃO: Tabagismo, relação cintura-quadril, antecedentes de hipertensão arterial e de diabetes, história familiar de insuficiência coronariana, níveis séricos de LDL-colesterol e de HDL-colesterol encontram-se independentemente associados com IAM na região metropolitana de São Paulo.
