Utilization of dental services by rural riverside populations covered by a Fluvial Family Health Team in Brazil.

INTRODUCTION: Rural riverside populations of Brazil face several difficulties to access health services. The Brazilian National Primary Care Policy implemented the Fluvial Family Health Teams (FFHT), which is a specific primary care team arrangement for these territories. The aim of the study was to assess the use of dental services by adults living in rural riverside areas covered by a FFHT. METHODS: A household-based cross-sectional survey was carried out with a rural riverside population of 38 localities on the left bank of the Rio Negro, Manaus, Amazonas, representative of the area covered by the FFHT. Stratified random sampling was calculated based on the number of adults and households in each riverside locality. An electronic questionnaire was used to obtain information on sociodemographic and oral health conditions, and the utilization of dental services. After descriptive analysis, logistic regression analyses were performed to estimate the odds ratios for the outcome 'use of dental health services over the past 12 months'. RESULTS: A total of 492 individuals, aged 18 years or more, from 38 rural riverside areas were assessed. The mean age of participants was 43.5 years (standard deviation 17.0), ranging from 18.0 to 90.7 years. Of these participants, 3.1% had never been to a dentist and 21.9% had been to a dentist more than 3 years ago. Among those who attended the dental service, 77.4% of appointments occurred in public health services. Dental pain over the previous 6 months (odds ratio (OR)=2.44; 95% confidence interval (CI) 1.51-3.96), higher education (OR=2.62; 95%CI 1.23-5.56), most recent appointment in public health services (OR=1.86; 95%CI 1.19-2.93), edentulism (OR=0.38; 95%CI 0.17-0.85) and dissatisfaction with oral health (OR=0.59; 95%CI 0.38-0.93) were associated with the dental services utilization. CONCLUSION: The study results revealed that approximately a quarter of the individuals did not use dental services over the previous 3 years or have never used them. Despite the increase in access provided by the FFHT, edentulous individuals, individuals dissatisfied with their oral health, and those with lower levels of education were less likely to use dental services, while individuals who experienced dental pain sought dental services more frequently. These findings suggest that the healthcare model offered to this population must be rearranged.

Extended pelvic resections for the treatment of locally advanced and recurrent anal canal and colorectal cancer: technical aspects and morbimortality predictors aftet 24 consecutive cases.

OBJECTIVE: to evaluate the profile of morbidity and mortality and its predictors related to extensive pelvic resections, including pelvic exenteration, to optimize the selection of patients and achieve better surgical results. METHODS: we performed 24 major resections for anorectal pelvic malignancy from 2008 to 2015 in the Instituto do Câncer do Ceará. The factors analyzed included age, weight loss, resected organs, total versus posterior exenteration, angiolymphatic and perineural invasion, lymph node metastasis and overall and disease-free survival. RESULTS: the median age was 57 years and the mean follow-up was ten months. Overall morbidity was 45.8%, with five (20.8%) serious complications. There were no deaths in the first 30 postoperative days. The median overall survival was 39.5 months, and disease-free survival, 30.7 months. Concomitant resection of the bladder was an isolated prognostic factor for higher risk of complications (87.5% vs. 26.7%, p = 0.009). Angiolymphatic invasion and lymph node metastasis did not reach significance with respect to disease-free survival. CONCLUSION: treatment of advanced anorectal tumors is challenging, often requiring combined resections, such as cystectomy and sacrectomy, and complex reconstructions. The magnitude of the operation still carries a high morbidity rate, but is a procedure considered safe and feasible, with a low mortality and adequate locoregional tumor control when performed in referral centers. OBJETIVOS: avaliar o perfil de morbimortalidade e seus fatores preditivos relacionados às ressecções pélvicas extensas, incluindo a exenteração pélvica, com o intuito de otimizar a seleção dos pacientes e obtenção de melhores resultados cirúrgicos. MÉTODOS: foram realizadas 24 grandes ressecções pélvicas por neoplasia maligna anorretal de 2008 a 2015 no Instituto do Câncer do Ceará. Os fatores analisados incluíram idade, perda de peso, órgão ressecados, exenteração total versus posterior, invasão angiolinfática e perineural, metástase linfonodal e sobrevida global e livre de doença. RESULTADOS: a mediana de idade foi 57 anos e o tempo médio de seguimento foi dez meses. A morbidade global foi 45,8%, com cinco (20,8%) complicações graves. Não houve óbito nos primeiros 30 dias de pós-operatório. A sobrevida global média foi 39,5 meses e a sobrevida livre de doença foi 30,7 meses. A ressecção concomitante da bexiga foi fator prognóstico isolado com maior risco para complicações (87,5% vs. 26,7%, p=0.009). Invasão angiolinfática e metástase linfonodal não alcançaram significância com relação à sobrevida livre de doença. CONCLUSÃO: o tratamento dos tumores anorretais avançados é desafiador, necessitando frequentemente de ressecções combinadas, como a cistectomia e sacrectomia, além de reconstruções complexas. A magnitude da cirurgia ainda carrega uma elevada taxa de morbidade, porém é um procedimento considerado seguro e factível, com uma baixa mortalidade e adequado controle locorregional tumoral quando realizado em centros de referência.

Solitary schwannoma of the cecum: case report and review of the literature.

A 78-year-old woman presented with an abdominal mass diagnosed by ultrasound and computed tomography. The patient underwent a laparotomy, during which a retroperitoneal tumor adherent to the cecum wall was identified. Microscopically, it showed spindle-cell proliferation in whorls, with low mitotic count (2 per 50 high-power fields) and was strongly positive for S-100 protein and vimentin. The final diagnosis was benign schwannoma of the cecum and no further treatment was required. Large intestine schwannomas are extremely rare tumors and only a few cases of schwannoma of the cecum have been reported to date.
