ABSTRACT The wide eco-bio-social intervention generated by the SaoFrancisco River Integration Project (PISF) may contribute to the dispersion or introduction of schistosomiasis intermediate hosts in areas without prior recording. The objective was to characterize the limnic malacofauna and its distribution along watersheds involved in the PISF. A cross-sectional study based on the collection of mollusks from 33 water bodies, from Aurora, Brejo Santo, Jaguaretama, Jaguaribara, Jati e Mauriti municipalities in the Ceara (CE) State was developed. The conchological characteristics were used to identify snails at the genus level. The snails of the genus Biomphalaria were analyzed for the presence of Schistosoma mansoni cercariae and the molecular identification (only mollusks from Brejo Santo-CE) for differentiation between species. The following species were found: Biomphalaria sp.; Drepanotrema sp.; Melanoides sp.; Physa sp.; and Pomacea sp. Pomacea sp. (75.8%) and Biomphalaria sp. (72.7%) were the most prevalent species. All municipalities showed Biomphalaria sp. Biomphalaria straminea (Porcos Stream) and Biomphalaria kuhniana was identified in the Boi 1 and Cipo reservoirs (Brejo Santo). The evaluated municipalities under the influence of the PISF present areas with potential for schistosomiasis transmission. It is necessary to intensify control actions and health surveillance in these areas.

Abstract INTRODUCTION: The development of the São Francisco River Integration Project [Projeto de Integração do Rio São Francisco (PISF)] in the State of Ceará, Brazil, has resulted in environmental and socioeconomic changes with potential risks to public health. We aimed to determine the presence of Schistosoma mansoni infections in schoolchildren (aged 7-14 years) and workers from the construction site in an area under the direct influence of the PISF in the municipality of Brejo Santo-CE, to aid in the prevention and control of schistosomiasis. METHODS: We conducted a cross-sectional study using two S. mansoni-detection methods: detection of S. mansoni eggs by the Kato-Katz parasitological method in stool samples (assessed in triplicate for each sample) and S. mansoni circulating cathodic antigen by the point-of-care immunochromatographic rapid test (POC-CCA) in urine. RESULTS In general, the positivity rates for S. mansoni detection were 1.9% (2/106) among schoolchildren and 2.9% (4/138) among workers. No child had evidence of S. mansoni eggs in their stools; 1.9% tested positive by the POC-CCA method. Among workers, two (1.4%) tested positive by the Kato-Katz test and three (2.2%) by the POC-CCA test. If the POC-CCA test results that were scored as traces were considered negative, then the positivity rates dropped to 0.9% and 0.7% for schoolchildren and workers, respectively. CONCLUSIONS: The active transmission of schistosomiasis in a region covered by the PISF was recognized, reinforcing the necessity to consolidate surveillance and control actions, as well as structural sanitation measures to reverse the social determinants of the disease.

Introduction  Fibrovascular polyps (FVPs) are rare benign tumors originating in the cervical esophagus, and, rarely, in the hypopharynx. A case of FVP from the larynx has not yet been described in the literature. Objectives  To discuss a unique case of FVP originating in the larynx. Resumed Report  A 58-year-old woman presented with a 6-month history of progressive dysphagia. Endoscopic exams identified an elongated polypoid lesion originating from the mucosa of the epiglottis and the right pharyngoepiglottic fold. Excision of this mass under direct laryngoscopy revealed an 11.5 × 0.8-cm polypoid lesion, histologically diagnosed as an FVP. Conclusion  The location of this FVP is important because, despite being a benign tumor, it carries a potentially lethal risk of upper airway obstruction.

Os tumores neuroendócrinos primários de mama (TNPMs) são incomuns e não há consenso quanto a tratamento e prognóstico. No presente trabalho, foram revisados os diagnósticos de 1.184 pacientes com câncer de mama atendidos no Hospital das Clínicas da Faculdade de Medicina de Ribeirão Preto da Universidade de São Paulo (HCFMRP/USP), identificando três casos que preenchiam os critérios de TNPM, segundo classificação estabelecida pela Organização Mundial da Saúde (OMS) em 2003. Foram avaliados os achados clinicopatológicos e imuno-histoquímicos e as terapias realizadas, buscando caracterizar os padrões histopatológicos e de comportamento distintos dos carcinomas convencionais de mama.

Primary neuroendocrine breast carcinomas (NECs) are uncommon. Moreover, there is no consensus as to its treatment and prognosis. In this study, the diagnoses of 1,184 cases of breast cancer treated at Hospital das Clínicas da Faculdade de Medicina de Ribeirão Preto/Universidade de São Paulo (HCFMRP/USP) were reviewed. Three among them fulfilled the criteria for primary NEC according to the classification established by the World Health Organization (WHO) in 2003. Clinicopathological, immunohistochemical features and treatments were assessed in order to characterize histopathological and distinct patterns of conventional breast carcinomas.

Este é o primeiro estudo a avaliar prevalência de cefaléias entre índios tuiniquins do Brasil. A prevalência de cefaléia encontrada nesta população foi alta, sendo que a migrânea foi a mais frequente. Encontrou-se maior prevalência de cefaléias entre as mulheres do que entre os homens. O impacto da cefaléia foi considerável, sendo maior entre os portadores de migrânea do que nas cefaléias não migranosas. Cinquenta por cento dos indivíduos com cefaléia recebiam atendimento médico devido a este problema, através do Programa de Saúde da Família (PSF). O tratamento empregado consistia apenas em analgésicos comuns para alívio das crises. Nenhum indivíduo estava em uso de tratamento profilático.

This is the first study to evaluate the prevalence of headache and migraine among Tupiniquim Brazilian natives. A high prevalence of headache was found and the most prevalent headache was migraine. Women were more commonly affected than men. A high impact of headache was found, especially among migraineurs. Half of the headache sufferers were under medical assistance for headache given by the government Family Health Program (PSF). Most of them declared to use common analgesics. None of them was taking prophylactic therapy for this medical problem.
