Human papillomavirus (HPV) type-16 DNA sequences were found in 26/53 (49%) and HPV type-18 in 5/53 (9%) of penile cancers. In only one specimen was HPV18 found on its own. HPV16 sequences were integrated into the host cell chromosomes although some monomeric and oligomeric free forms of DNA were detected in a few tissues. HPV18 was, as far as detectable, free and unintegrated in all tissues tested. HPV16 DNA was also detected in 40% of cases of carcinoma of the cervix in 19 women from the same social groups as the males. The viral DNA in the female cases was a mixture of integrated and free forms. The DNA binding protein (ICSP 11/12) of herpes simplex type 2 (HSV2) was not detected in 10 penile cancers tested with a monoclonal antibody.
Human papillomavirus (HPV) is responsible for the rise in the incidence of cancer in the oropharynx, tonsils, and base of the tongue (i.e., HPV-related subsites). HPV triggered the changes in the epidemiology of oropharyngeal and oral cavity cancer (OPC/OCC) in Asia, Europe, North America, and Oceania. Hence, the incidence of cancer in HPV-related subsites is augmenting, while that in other HPV-unrelated subsites is decreasing. In South America, although the incidence of HPV-positive tumors has gradually increased, there is an atypically low prevalence of HPV in people with OPC/OCC. To clarify whether this dramatic shift in incidence trends also occurred in this population, we estimated the burden of HPV on the incidence trends of OPCs/OCCs in São Paulo city in Brazil. In this populationbased study, we categorized OPCs/OCCs by HPV-related and HPV-unrelated subsites. We used Poisson regression to assess the age-standardized incidence rates (ASRs) stratified by sex and age groups, as well as to examine the age-period-cohort effects. There were 15,391 cases of OPCs/OCCs diagnosed in HPV-related (n = 5,898; 38.3%) and HPV-unrelated (n = 9,493; 61.7%) subsites. Overall, the ASRs decreased for most subsites, for both sexes and for all age groups, except for HPV-related OPC/OCC in young males and females, which increased by 3.8% and 8.6% per year, respectively. In the birth-cohort-effect analysis, we identified an increasing risk for HPV-related OPC/OCC in both sexes in recent birth cohorts; however, this risk was sharply decreased in HPV-unrelated subsites. Our data demonstrate an emerging risk for HPV-related OPC/OCC in young people, which supports prophylactic HPV vaccination in this group.
RESUMODesde o advento do Código de Defesa do Consumidor, evidenciou-se no mundo jurídico o aumento da proteção legal conferida ao contratante de prestação de serviços, tendo em vista a sua condição de hipossuficiência em relação ao profissional prestador de serviço estabelecida pela Lei nº. 8.078/90 nas relações de consumo. Tornando-se perceptível a partir de então um crescimento no número de ações movidas por pacientes/clientes contra os cirurgiões-dentistas.Nesse contexto, torna-se imprescindível que esses profissionais disponham de uma completa documentação dos pacientes, idônea a comprovar a qualidade e eficiência da prestação do respectivo serviço. Além disso, a documentação é importante na resolução de impasses de natureza penal. Uma alternativa factível para o equacionamento dos transtornos gerados pela utilização de prontuários comuns, como a necessidade de espaços físicos para armazenagem, bem como a dificuldade para acessar os dados disponíveis nos prontuários, surge na possibilidade da inclusão do prontuário digital. Entretanto, os arquivos digitais, estão sujeitos a manipulação através de recursos tecnológicos de informática, o que lhes diminui a capacidade probante perante a Justiça, e retira-lhes a aptidão para único meio de prova nos processos judiciais. O presente trabalho pretende discutir aspectos relativos à utilização do prontuário
The present study was conducted to evaluate the socioeconomic inequality related to lung cancer mortality rates and trends between 2000 and 2015 according to gender in Brazil. We retrieved the death records for cases of lung cancer (ICD-10 C33 C34) from 2000 to 2015 in adults age 30 years and older in Brazilian Regions from official databases (DATASUS) and corrected for ill-defined causes. The Prais-Winsten regression method and Pearson correlation were applied. The results were considered statistically significant when p < 0.05. The correlation between the lung cancer mortality rates and the HDI decreased when the rates for the first and last years of the historical series were compared in men (r = 0.77; r = 0.58) and women (r = 0.64; r = 0.41). However, the correlation between the trends in the lung cancer mortality rates and the HDI was negative in men (r = − 0.76) and women (r = − 0.58), indicating larger reductions (or smaller additions) among the Federative Units with the highest HDI, in contrast to trends reflecting a greater increase in those with the lowest HDI. Our results suggest a relevant inequality in the trends of mortality from lung cancer in Brazil.
Although São Paulo is the most populous city in Brazil - one of the world’s most violent countries - a significant reduction in its homicide mortality rate (HMR) has been detected. This study aims to estimate the effects of age, period, and birth cohort on the trend of homicide mortality according to sex in the city of São Paulo, from 1996 to 2015. An ecological study was undertaken with data on deaths by homicide for both sexes, in all age brackets, in the city of São Paulo. Poisson models were adjusted for each sex to estimate the age-period-cohort effects. In total, 61,833 deaths by homicide were recorded among males and 5,109 among females. Regardless of the period, the highest HMR occurred in the 20-24 age bracket. Higher HMRs were found in those born in the 1970s and 1980s. The complete model, with age-period-cohort effects, were the best fit to the data. The risk of death by homicide declined over the periods, with lower intensity in the final five years (2011-2015), for both males (RR = 0.48; 95%CI: 0.46; 0.49) and females (RR = 0.52; 95%CI: 0.47; 0.57). A reduction was found in the risk of homicide, regardless of the sex or age bracket, and also in recent cohorts. However, the intensity of such reductions has been decreasing over time, which suggests that the public policies adopted have limited potential to maintain these achievements.
informática se tornou essencial na área da saúde. Políticas de informatizaçãovem sendo implantadas pelo governo brasileiro para capacitar profissionais e acadêmicos, estabelecendo novas relações com a tecnologia e permitindo idealizar novas aplicações de recursos computacionais. O objetivo desse trabalho é relatar e avaliar uma experiência de ensino baseada na Aprendizagem Baseada em Projetos em uma disciplina de Informática Aplicada à Saúde para graduação. Na disciplina, foi proposto o desenvolvimento de aplicativos móveis para a saúde. A turma contou com a participação de 21 alunos que foram avaliados qualitativamente por dois surveys. Todos os alunos completaram a disciplina e relataram um impacto positivo na sua formação. Cinco aplicativos foram construídos e uma nova percepção de tecnologia foi adquirida, 15 estudantes afirmaram estar motivados para aprender novas tecnologias e 16 se consideraram aptos para desenvolver novos aplicativos.
This study assessed the accuracy of fractal analysis (FA) to estimate chronological age and sex in Brazilian adults for forensic investigations. The gender-balanced sample comprised lateral cephalometric radiographs of 120 individuals, stratified according to age (20-29, 30-39, 40-49, 50-59 years) and sex (female and male). A trained calibrated examiner measured the fractal dimension (FD) of the mandibular ramus and mandibular angle. Linear regression and multiple logistic discriminant analysis were carried out to explore the accuracy of FA. For all analyses, p-values < .05 indicated statistical significance. Overall, mean FD values were 1.49±0.10 for the mandibular ramus and 1.48±0.09 for mandibular angle. Results were more accurate in males than females for discriminating age and sex. The multiple discriminant analysis indicated that FA distinguished sex in 61.7% males and 58.3% females. In addition, the mean difference between actual and predicted value was 9.5 years and 10.1 years for men and women, respectively. Fractal analysis accurately identified sex- and age-related differences in the trabecular pattern of the mandible of Brazilian adults, confirming its utility for forensic investigations. Further studies investigating other populations are needed to assess the accuracy of FA for Forensic Dentistry.
