Ductal carcinoma in situ (DCIS) is a tumor with long term survival and low local recurrence rate. Although the progression of these lesions is rare, the current guidelines recommend breast conservating surgery (BCS) with adjuvant radio and/or endocrine therapy, often resulting in an overtreatment for patients. The aim of this single-center study was to evaluate the long-term outcome of the breast conservating surgery of DCIS followed by adjuvant radio and/or endocrine therapy and to identify prognostic factors associated with the risk of recurrence.Patients treated for DCIS with BCS and radiation therapy between March 2006 and January 2019 were retrospectively reviewed using a prospectively maintained database. Analysis of the potential risk factors was performed to evaluate the risk of subsequent ipsilateral and contralateral recurrence.Out of 2894 patients, two hundred eighty-eight (10%) patients were treated for DCIS. After a median follow-up of 85 months (IQR 27-124), the incidence of recurrence was 6% (18 patients). Nine of them (3%) had an ipsilateral local recurrence (LR) with a median disease-free survival of 19 months (IQR 12-35). The remaining nine patients had contralateral metachronous breast cancer (CBC) with a median DFS of 29 months (IQR 14-36). Margin status, multifocality, hormone receptor status and Her-2/Basal-like subtype were identified as risk factors for the local recurrence with a OR of 5.58 (1.44-21.54), 7.46(1.89-24.48) 0.25 (0.06-0.96) and 4.86 (1.26-18.71) respectively.DCIS had been confirmed to have long term survival. Margin status, multifocality, hormone receptor status and Her-2/Basal-like subtype could be identified as reliable risk factors for the progression of the disease.

Recurrent outbreaks of oral infection and isolated cases characterize the new epidemiological scenario of Chagas disease (CD) in the Brazilian Amazon. Acute Chagas disease (ACD) is common in Pará and Amazonas, Northeastern and Northwestern Brazilian Amazonia. In the present study, we describe the first molecularly characterized autochthonous case of ACD in Rondônia, Southwestern Amazonia. The patient, a 39-year-old male resident in the small city of Cujubim, presented typical ACD symptoms: fever, asthenia, myalgia, progressive dyspnea, swelling of the legs, and tiredness at minimal efforts, all compatible with ACD and indicative of cardiac involvement. A thick blood drop test revealed trypomastigote forms of

Os triatomíneos, popularmente conhecido como barbeiro, sendo tal o agente transmissor da doença de Chagas no Brasil e nas Américas. Em Porto Velho, município de Rondônia, ainda não se tem estudos de notificações que venha divulgar números de casos da doença de Chagas notificado. O objetivo do estudo foi realizar um levantamento da ocorrência do vetor da doença de Chagas em uma área periurbana da cidade Porto Velho, no bairro Ronaldo Aragão, na linha Progresso. Esta localidade foi selecionada por constante ocorrência do inseto vetor, os quais após coletados por moradores do domicilio foram enviados ao laboratório de entomologia do Centro de Controle de Zoonoses e posteriormente ao LACEN-RO. As coletas entomológicas tiveram duas etapas, em campo e em laboratório, a análise do material coletado foi no laboratório de entomologia médica no LACEN-RO. Os resultados obtidos das 16 coletas, através de busca ativa, com nenhum registro do vetor da Chagas. Mas das buscas passivas, obteve-se um total de 14 exemplares de triatomíneos, das quais houve prevalência da espécie Rhodnius robustus e apenas 01 exemplar de Rhodnius pictipes, e dentre estes, um triatomíneo estava positivo com Trypanosoma cruzi. Sugerimos novas coletas entomológicas, objetivando um maior numero de exemplares de triatomíneos, tanto na área deste estudo, como em outras localidades neste município e outros ecótopos, e ainda realizar o isolamento das amostras de Trypanosoma cruzi para fins da possibilidade da realização de testes moleculares.ABSTRAT The triatomíneos, popularly are known as barber, being such the transmitter agent of the Chagas disease in Brazil and in the Americas. In Porto Velho, city of Rondonia, there are not studies of notifications that come to divulge numbers of cases of chagas notified. The objective of the study was to do a survey of the occurrence for Chagas’ disease vector in the suburbs of the city of Porto Velho, in the Ronaldo Aragao, neighborhood ,in the line Progress. This locality was selected by constant occurrence of the insect vector, which after collected for inhabitants of the home are sent to the laboratory of entomology of the Control Center of Zoonoses and later to the LACEN-RO. The entomologicals collections had two stages, in field and in laboratory, the analysis of the collected material was in the laboratory of medical entomology in the LACEN-RO. The obtained results of the 16 collections, through passive searches, it was obtained a total of 14 types of of triatomíneos , of which had prevalence of the Rhodnius robustus species and only 01 type of Rhodnius pictipes, and among these, a triatomíneo was positive with Trypanosoma cruzi. We suggested new entomologicals collections, objectifying a larger number of triatomíneos types, so much in the area of this study, as in other localities in this city and other environments, and still to do through the isolation of the samples of Trypanosoma cruzi for ends of the possibility of accomplishment of molecular tests.
