Dissertação Acesso aberto (Open Access) Doadores de sangue positivos em triagem sorológica para doença de Chagas no Acre: necessidade de adequação e orientação diagnóstica(Universidade Federal do Pará, 2011-01-24) SILVA, Pablo Rodrigo de Andrade e; PÓVOA, Marinete Marins; http://lattes.cnpq.br/2256328599939923This study, which involved 77,893 blood donors who attended for the first time the Blood Center of Acre, from January 1997 to December 2008, aimed to: 1) to identify individuals with positive serology for Chagas disease, 2) characterize clinically, individuals with positive serology for Chagas' disease and 3) properly orient individuals serologically positive for therapy advocated. The sample consisted of 91.6% of male patients, with an average age around 47, all residents of the state of Acre. Serological screening was performed with the application of the ELISA positive results with 102 of these, 12 were included and subjected to confirmatory testing, of whom 11 had confirmed the positive result. According to the evaluation of complementary exams (ECG, echocardiography and endoscopy), a donor had installed the cardiac and the other an indeterminate form of the disease. You must provide the confirmatory test for Chagas disease in the routine of blood banks in order to ensure timely referral to a qualified medical assistance to that blood donor who became Chagas’ patients.Tese Acesso aberto (Open Access) Hidatidose policística no Estado do Acre: contribuição para o diagnóstico, tratamento e prognóstico dos pacientes(Universidade Federal do Pará, 2010-06) SIQUEIRA, Nilton Ghiotti de; PÓVOA, Marinete Marins; http://lattes.cnpq.br/2256328599939923The echinococcosis is a zoonosis whose etiological agents are nematodes of the genus Echinococcus. There are five species of Echinococcus, two of them, E. oligarthrus (Diesing, 1863) and E. vogeli (Rausch & Bernstein, 1972) only occur in neotropical areas. The echinococcosis by E. vogeli causes multiple hydatid cysts, mainly in the liver of intermediate hosts, of which one is the human being. The lack of knowledge about the disease makes the diagnosis is delayed or even misleading. The lack of systematic information on treatment is also difficult to assess the results and prognosis of patients with peritoneal and hepatic lesions caused by E. vogeli. Here we describe the clinical features of patients, we propose a radiological classification protocol used in the classification of alveolar echinococcosis (E. multilocularis "PNM" Classification, Kern et al., 2006), which was also suitable for polycystic echinococcosis (E. vogeli) and describe a therapeutic option for the treatment of hydatid disease which previously had only been used for cases of cystic echinococcosis (E. granulosus, PAIR-Puncture, Aspiration, Injection, Reaspiration, Brunnetti et al., 2001). A prospective cohort study was initiated in 1999 and by 2009 included 60 patients. We describe the main symptoms and signs: pain in upper abdomen (65%) and hepatomegaly (60%) and patients were classified according to the "PNM" classification and submitted to three therapeutic modalities: (i) chemotherapy with albendazole at a dose of 10mg/kg/day, (ii) surgical removal of cysts or (iii) percutaneous puncture of the cysts- PAIR. After exclusion of two cases, due to inadequacy of the research protocol, the groups were distributed as follows: treatment with albendazole: n = 28 (48.3%, 28/58), surgical therapy: n = 25 (52.1%; 25/58) and PAIR: n = 5 (8.1%, 5 / 58). The results were stratified according to outcome of therapy: "Cure", represented by the disappearance of lesions after clinical or surgical treatment, "clinical improvement", defined as asymptomatic patients without weight loss and physiological functions preserved, "No Improvement" included patients who remained symptomatic, "Death" and "No Information", the monitoring did not allow a conclusion about the outcome. The three treatment groups together demonstrade lethality rate of 15.5% (9 / 58), "no improvement" 1.7% (1 / 58), "clinical improvement" in 40.0% (23/58) and "cure "in 32.8% (19/58). Regarding the outcome "death", there was no difference between therapies with albendazole or surgical treatment with 4 (14.2%) and 3 (12%) deaths respectively, but in the first group, albendazole, the outcome "cure" was 4.3% (1 / 23) and "clinical improvement" 74.0% (17/23), whereas in the "surgery" to "cure" represented 71.0% (17/24) and "clinical improvement" 16.7 (4 / 24). Therapy "PAIR" was associated with a lethality rate of 40% (2 / 5), cure in 20% (fifth) and clinical improvement in 40% (2 / 5). The "PNM" classification was useful to indicate such therapy in cases of polycystic hydatid disease. In conclusion, in the series studied surgical therapy has better results in the clinical therapy on the outcomes "cure" and "clinical improvement". The treatment for PAIR needs further studies.Dissertação Acesso aberto (Open Access) ICB/PPGBAIP Estudo da ocorrência e perfil de suscetibilidade aos antimicrobianos de Staphylococcus aureus isolados de pacientes e profissionais de saúde na Unidade de Terapia Intensiva de hospital público de Rio Branco-AC(Universidade Federal do Pará, 2011-02-07) LAVIOLA GARCÊZ, Poliana Torres; LOUREIRO, Edvaldo Carlos Brito; http://lattes.cnpq.br/2685418720563351The nosocomial infection is a serious public health problem worldwide, mainly in patients admitted to the Intensive Care Unit, which are subject to greater risk due to the severity of clinical symptoms, constant use of broad spectrum antibiotics and frequency of use of invasive procedures. Staphylococcus aureus is a major pathogen that colonizes healthy individuals and is also responsible for infections in hospitalized patients. This study aimed to identify the resistance profile, main sites affected by infection and possible risk factors associated with infection or colonization by S. aureus isolated from patients and healthcare professionals from the Intensive Care Unit of Hospital Emergency and Emergency, Rio Branco (HUERB) – Acre. We developed a cross-sectional study, conducted between January to August 2009. To search for carriers, biological samples were collected from microbiota of patients and professionals and professionals hand washing. For a survey of cases of patients with nosocomial infection were collected biological samples from sites suspected of being affected, 72 hours from the date of admission until discharge, transfer or death. Of the 62 patients enrolled in the study, 19.3% were carriers and 6.4% developed nosocomial infections by S. aureus, and 35 professionals, 28.6% were carriers of S. aureus. It was the second most bacterial species isolated from patients, and was the fifth most isolated from cases of nosocomial infection. There was no statistical evidence for the variable state of coma, use of invasive procedures and state of carrier patient are considered risk factors for acquiring nosocomial S. aureus in this study. The anatomical sites affected by IH by S. aureus were the respiratory tract ( n=2), followed by blood (n=1). The sample catheter tip was responsible for one insulated. One (1.6%) patient developed IH by MRSA, and 5 (8,1%) patients and 2 ( 5.7%) professionals were MRSA carriers, low occurrence as it relates to the results of the rest of Brazil and world. We also emphasize the incidence of MRSA over MSSA and low antomicrobial resistance of MRSA demonstrating that the UTI-HUERB, the IH S. aureus does not constitute a public health problem. There were no isolates of S. aureus resistant to vancomicina, wich can be considered a therapeutic option for cases of IH by MRSA. It is worth emphasizing the importance of this study in Acre State, for being the first of its kind in the UTI, involving S. aureus and MRSA.Tese Acesso aberto (Open Access) Inquérito com paracoccidiodina em cinco cidades do Estado do Acre(Universidade Federal do Pará, 2011-09-30) FIGUEIREDO, Mediã Barbosa; ISHAK, Ricardo; http://lattes.cnpq.br/5621101706909450Paracoccidioidomycosis constitutes an important public health problem in Latin America. In Brazil, this disease is less frequent in North and Northeast regions, predominating the endemic areas in the Southeast. Despite the physiographic conditions of the North region favoring the development of Paracoccidioides brasiliensis, even so, the case reports are scarce. Perhaps this is due to the little consideration of deep mycoses about the differential diagnosis of chronic medical conditions, justified by the fact that the region is not considered endemic. With the objective of describing the prevalence of paracoccidioidomycosis in five cities of Acre, a cross-sectional population-based study was conducted, through a survey with the paracoccidioidin intradermal. The reading of the intradermal test was performed within 24 and 48 hours, being considered reactors the people with hardened areas of 5mm or more in diameter. Four hundred thirty-nine (439) people were studied and paracoccidiodomycosis-infection in the 48-hour reading was 41.2%. The findings of this study indicate that P. brasiliensis infection causes a considerable number of people in the study area to get infected, and therefore future clinical-epidemiological and mycological studies should better clarify the natural history of mycosis in this region.
