Análise higiênico-sanitária da carne do caranguejo-uçá (Ucides cordatus) beneficiada em dois municípios litorâneos do Estado do Pará
(Universidade Federal do Pará, 2002) CÉSAR, Kátia Lamarão Vieira; REZENDE, Manoel Barbosa de
Among the products of animal origin, the crab is held as one of the victuals more susceptible to the deterioration process due to is specific chemical composition, activities of autoliticas enzyme and to the close pH of the neutrality. Beyond of those intrinsic factors related to the crustacean, the process of extraction of its meats is accomplished, in the great majority of the times, in unsatisfactory hygienic-sanitary condition, causing, like this, a high text of contamination of these. With the objective of analyzing the microbiologic, microscopic and parasitical quality of the crabmeat traded in two municipal districts of Pani (Sao Caetano de Odivelas and Braganya), 30 samples were researched, acquired from the meat collectors, in its points of collection. In the microbiologic analysis, presence was observed, in high levels, of fecal coliforms and S. aureus, in both municipal districts, however Salmonella (s. panama: sorogrupo D) was only detected in Braganya/Vila de Caratateua. It is stood out that, great part of collection points presented their samples out of the effective legal patterns in the current Brazilian legislation. The microscopic analysis revealed constant dirt presence (fragments and stick chips, seed, fibber and chips of vegetable origin, for the human, excrement and insect larva). However, the parasitical analysis was negative for the detection of cysts of protozoarius (E. histolytica/E. dispar and G. lamblia). The results reveal the precariousness of the hygienic-sanitary conditions of the researched samples, indicating this way the need of being created, on the part of the competent authorities, a registration of the Ministerio da Agricultura e Secretaria da Agricultura do Estado, so that the manufacturing and the commercialization of this product are made in agreement with Brazilian and state sanitary rules.

Infecção congênita pelo citomegalovírus: estudo realizado na Fundação Santa Casa de Misericórdia do Pará
(Universidade Federal do Pará, 1997-11-14) WEIRICH, Judith; SANTOS, Elisabeth Conceição de Oliveira; http://lattes.cnpq.br/2720400830437723; REZENDE, Manoel Barbosa de
Cytomegalovirus (CMV) is a DNA virus classified in the Hespesviridae family and Betaherpesvirinae subfamily. It has a worlwide distribution and may cause congenital and perinatal infection, as well acquired infection in children and adults. CMV has been associated with high rates of morbidity and mortality among immune deficient or immune suppressed patients. This investigation was carried out from November 1994 to May 1995 in the maternity of a local public hospital - ''Fundação Santa Casa de Misericórdia do Pará"- and the main objective was to assess the incidence of congenital CMV infection among neonates in Belem, Brazil. We enrolled 663 newborns and their mothers to participate in our study. The weights of neonates ranged from 900 to 5450 g (mean of 3046 g) and low birth weights were recorded in 11,4% of them. For diagnostic purposes, clinical specimens (spittle) were inoculated on to culture cell lines prepared from human foreskin fibroblasts, yielding virus isolation in 21 (3,2%) of patients. Cord blood samples have been tested for the presence of CMV -specific IgM by using ELISA, with positive results in 14 (2,1%) patients. Differences of sensitivities between these methods were analysed by using the McNemar' test (Comparing proportions in paired groups) and the X2 test of homogeneity, as appropriate. Virus isolation proved to be more sensitive than serology, with p values of 0,0233 and less than 0,01 for the former and latter statistical tests, respectively. Six (28,5%) among the 21 infected neonates were shown to be congenitally infected, presenting with typical signs and symptoms suchs as: microcephaly (4), prematurity (3), hepatosplenomegaly (2), low birth weight (2) and jaundice (1). Sera from mothers were also tested for the presence of CMV-antibody by ELISA The detection of specific IgG was recorded in 90,2% of them, whereas IgM seropositivity was detected in 4 (19,0%) of those 21 mothers of infected children. Data gathered during routine interviews with mothers revealed low social economical leve1 and indicated that 26,4% of them had no prenatal medical assistance. Their ages ranged fiom 12 to 42 years (mean age of 22,2) and all mothers of CMV-infected children were aged less than 25 years.

Perfil epidemiológico dos pacientes com tuberculose pulmonar atendidos na Unidade Básica de Saúde da Pedreira
(Universidade Federal do Pará, 2003) BARBOSA, Heloisa Helena Moreira de Moraes; REZENDE, Manoel Barbosa de
The Pulmonary Tuberculosis is still one of the biggest public health problems all over the world, including Brazil. The control situation aggravates because it's difficult to implant an efficient program because of the proportion between the necessities and the available resources, and even for the limited covery and utilization of the installed capacity of attention, besides, in the end of the 80's, for the HIV propagation. With the aim, of describing the epidemiological profile of the patients infected with the pulmonary tuberculosis, attended in the Basic Health Unit of Pedreira Neighborhood, in the Belem of Para city. 143 patients, considering all rate of ages and sex, with pulmonary tuberculosis, were part of this study, all this data was collected between January of 2001 and July of 2002. It was analyzed the following aspects: signals and symptoms, baciloscopy, thorax radiology, number of communicants in home, antecedent case of pulmonary tuberculosis in family, time between the beginning of the symptoms and the beginning of the treatment, kinds of discharge of treatment, patient's provenance, school degrees, recidivistic cases, occupation and its qualification, familiar resources, daily meals, living conditions, kind of the house's wall, number of windows, number of rooms x the number of people, canalized water, electric light, kind of home fosse of the water closet, smoking and alcoholics practices. Results: Cough was the most frequent symptom with 89,51%; the positive result of baciloscopic test was 60,01%; the radiological founds with infiltration were 42,86%; 84,62% of the patients have at least one in-home communicant, 57,34% have at least one case of pulmonary tuberculosis in family; 65,04% were late 2 months to start the treatment after the symptoms had started; 94,23% received discharge for cure; 3,85% received discharge for quitting and 1,92% discharge for death; 78% from Belem; 7% are illiterate people and 51,75% have not completed the junior high school; 11,19% of recidivous; considering the people that have an occupation, 68,49% don't have qualification; 86% have income less than 6 minimum salaries; 43,68% of the patients are alcoholics. The conclusions were that the predominant sex and rate of ages were respectively male and from 16 to 45; the social, economic, cultural, living aspects were very poor, and it's very important to understand that this disease demonstrate its social determination. Therefor, the biological processes of health are part of the social life of the collectivity, by this way, the health and the diseases are equidistant points in the same process that is a part of a major ground called life. Sanitary education talk is a educational way to create a healthy habit that will certainly contribute to a better human's potentials development. This study proves the researches that were made before.

Prevalência da infecção pelo vírus da hepatite B em duas comunidades ribeirinhas de afluentes do Tocantins
(Universidade Federal do Pará, 2003) GADELHA, Maria Apolônia da Costa; REZENDE, Manoel Barbosa de
The infection by the hepatitis B virus reaches 5% of the world population, with areas of low, intermediate, and high endemism according to the variation in prevalence rates. The study aims to evaluate the prevalence of infection with hepatitis B virus (HBV) in two tributaries of the river communities of Tocantins, in order to assist with control of viral hepatitis for the Amazon region. We evaluated 58 patients living in the city of Igarapé-Miri (Panacuera and Pindobal Grande). The survey of serological markers for HBV (HBsAg, anti-HBs and anti-HBc), revealed the absence of HBsAg in both communities, while anti-HBc was positive in 3.84% of patients and in 12 Panacuera 5% at Pindobal Grande. The anti-HBs was positive in 3.4% and 6.25% Panacauera in Pindobal Grande. Given these results, we found that the prevalence rates of HBV infection in both communities were low compared to those found in other areas of the Amazon. However, these markers should be considered during the selection of donors within the community because of the risk of post-transfusion hepatitis. Prevention through vaccination should be done because individuals in these communities because they have risk factors, are predisposed to infection and may progress to cirrhosis, and hepatocellular carcinoma.

Prevalência de anticorpos para HTLV em indivíduos atendidos em um centro de diagnóstico para Anti-HIV
(Universidade Federal do Pará, 2000) BRÍGIDO, Helena Andrade Zeferino; REZENDE, Manoel Barbosa de
The researches are about the occurency of HTLV I and II infections increased after Acquired Immunodeficiency Syndrome (AIDS). In case of coinfection the AIDS has higher precocity in its development with modifications of its parameters control and the antiretroviral begining. This study presents the prevalence of HTLV IIII among patients attending the AIDS Reference Unit (URE-DIPE). A group of 588 patients from the URE-DIPE, 292 from Institute Evandro Chagas (IEC) and 295 of blood donors from HEMOPA was tested for the presence of antibodies to HTLV IIII using double ELISA and Western Blot. In the URE-DIPE the heterosexual population was the predominant, in both sexs, with 499 persons (84,9%). Although after the Anti-HIV result analysis, there is no significative difference in the sexual option. Seven patients (1,2%) were positive to HTL V I. The coinfection HTL V/HIV occurred in 3 cases, corresponding for 0,5% from the total. In the IEC, the serum positivity was detected in two cases (0,7%) to Anti-HTLV I and II. Comparing these 2 groups (URE-DIPE and IEC), the results didn't disagree with p=0,2345 and 0,4691, respectivitly. The population thats presents a higher sexual activity is the most and lEC do not permit to determine that in the first, the HTL V infection is the most incidence. Also, there is no significative difference between the heterosexual and homosexual infections. Therefore, the sexual contact is the dominant factor. The most afected ages are favourable the perinatal transmission. The serum positivity absent in the blood donors is compatible with the low prevalence of this group. It is agrees on the literature. Further studies are necessary in order to inform the health professionals and the whole population about prevention and controls.
