The infection caused by Toxoplasma gondii, Trypanosoma cruzi, Rubella virus, Cytomegalovirus (CMV) and Treponema pallidum, can reach the fetus via the placenta or transamniótica may cause different damage. The severity of the infection or even abortion, depend on the virulence of the strain of microorganism, the immune response of the mother and the period. The aim of this study was to analyze the results of serological, pathological and parasitological material for abortive infections with risk of vertical transmission, with emphasis on toxoplasmosis. They were invited to participate in the study, women who miscarried and complete or incomplete, attended at two public hospitals in Goiânia, Goiás, between the period June 2008 to June 2009. Were interviewed through a questionnaire and collected blood samples and abortive material. There were immunologic tests for toxoplasmosis, Chagas disease, rubella, cytomegalovirus and syphilis and pathology in cytogenetic. 55% of women were aged 20 to 30 years of age. The majority (68%) had gestational ages ranging from 7-14th weeks. 54.3% of women had completed high school or incomplete. Regarding the number of abortions, most women (69%) had only one abortion and minority (2.9%) were already in the fourth or fifth abortion. For the analysis of serology, infection with the risk of vertical transmission was more frequent with the CMV 97.1% positivity and then the rubella 95.2%. Toxoplasmosis has a percentage of 54.3%, Chagas disease by 1.9% and syphilis by 0.95%. The analysis of the biopsy showed that 63.1% showed inflammation and 34% absence of inflammation. Analysis of serological, pathological and parasitological of 105 women, 57 were seropositive for T. gondii. It was observed that 77.1% showed inflammation, detected in pathological examination. None has tested positive for Polymerase Chain Reaction (PCR) and inoculation in mice. This study demonstrated the high frequency of seropositive for CMV and rubella then toxoplasmosis, Chagas disease and syphilis in our country. The elucidation of the cause of miscarriage is still not routine in our country. These data showed that the prevalence of disease with risk of congenital transmission in patients with spontaneous abortion is important, more research is needed to elucidate the etiology of abortion. Women's health should receive more attention from our managers because primary care is the best and most efficient path to be followed in order to quality of life for mothers and their future children.

The gastroenteric viruses are important etiological agents of gastroenteritis in individuals of all ages. It is believed that individuals with deficits in the immune system (humoral and/or cellular), among them pregnant women and human immune deficiency virus (HIV)-seropositive women, are more susceptible to these viral infections. The rotaviruses, adenoviruses, astroviruses, and caliciviruses constitute are among the main causes of acute gastroenteritis in the world, and are accounted for high morbi-mortality rates, especially among children under five years of age. It is believed that, by the age of three, approximately 90% of all children in developing countries have antibodies to one or more of these agents. Neonatal infection does not exclude the possibility of re-infection, with different viral serotypes, however it protects the individual against severe disease. This study aimed at the detection of rotavirus, adenovirus, astrovirus e calicivirus in women seeing at the Hospital das Clínicas da Universidade Federal de Goiás (HC-UFG) and at the investigation of as association between the positivity to this viruses and the low immune status, characteristic in pregnant women and/or HIV-seropositive women. This was a prospective follow-up study of women seeing at the Gynecology and obstetrics (OB-GYN) sector of the HC-UFG aiming at the detection of gastroenteric viruses (rotavirus, adenovirus, astrovirus e calicivirus). For this, fecal samples were collected from 84 women, in the period from July-2006 to June-2007. For rotavirus detection, fecal samples were screened by polyacrilamide gel electrophoresis (PAGE) and by an immunoenzimatic assay (IEA). The calicivirus and astrovirus were detected by polymerase chain reaction post-reverse transcription (RT-PCR), and adenovirus detection was performed by an EIE. The astrovirus genotyping was conducted by Nested-PCR. Three-hundred and fourteen fecal samples were collected from a total of 84 women. From those 84 women, 29 were HIV-seropositive, 55 HIVseronegative, 45 were pregnant at the time, and 39 were not pregnant. The patients were aged between 16 and 67 years-old, and 47% of them had up to 30 years of age. From the total 84 patients, 19 (22.6%) were positive for calicivirus and/or astrovirus in at least one of the collected samples, as follows: calicivirus (14/19) and astrovírus (6/19), with the highest positivity rates being detected in the months of July and August (astrovirus) and September and October (calicivirus). None of the collected samples were positive for rotavirus or adenovirus. The association index between gastroenteric virus positivity and pregnancy, in the presence or not of HIV-seropositivity, was of 68.4% (13/19); however, there was no significant difference between the group of women that were not pregnant and the ones that were HIV-seronegative. The gastroenteric viruses were detected in a significant parcel (22.6%) of this population of adult women, and were represented by the caliciviruses (16.7%) and astroviruses (7.1%). Under the conditions of the present study, no association was found between pregnancy and/or positivity for HIV, as reducing factors for the immunological capacity of the women, and the detection of gastroenteric viruses; in conclusion, the pregnancy and/or HIV-seropositivity did not increase the chances of these women to be infected by these gastroenteric viruses.

(Universidade Federal de Goiás, 2012-03-23) MOTA, Eliane Duarte; SADDI, Vera Aparecida; http://lattes.cnpq.br/7496804650895441; KIPNIS, Ana Paula Junqueira; http://lattes.cnpq.br/1252262903952987
BACKGROUND: Colorectal adenocarcinoma (CRA) is a worldwide distributed pathology, and lymph node metastasis is associated with a poor prognostic outcome. Angiogenesis and lymphangiogenesis are correlated with metastasis. Vascular endothelial growth factor C (VEGF-C) and Cyclooxygenase 2 (COX-2) are molecules directly involved in those processes. We investigated the possible association of the expression of VEGF-C and COX-2 with clinical/pathology features and five year survival rate. MATERIALS AND METHODS: One hundred and thirty four cases of CRA from a Cancer Reference Hospital were randomly selected. The expression of VEGF-C and COX-2 was detected by immunohistochemistry and a univariate analysis was applied to evaluate the association between their expression and clinical stages, metastasis, and/or survival. RESULTS: COX-2 expression was observed in 98.67% of the adenocarcinoma cases while VEGF-C was found in 54.48% of the cases. COX-2 was highly expressed by all clinical stages of CRA, but its expression was not associated with LN metastasis, tumor infiltration or five years survival. A correlation was observed between LN metastasis and VEGF-C positivity (p=0.02) and clinical stages of the disease. The range of VEGF-C expressions was from 34.6% to 88.9% in stages 1 through 4, respectively. CONCLUSION: The majority of the CRA cases were positive for COX-2. It was observed association between the expression of VEGF-C and LN metastasis as well as with clinical stages of the disease, although no association was found to the overall five year survival rate.

Several infectious and parasitic diseases have been described as possible causes of cognitive loss, especially the neuroinfections that the location in the CNS, may evolve into frank dementia table (although subject to reversal). The vast possibilities as a result has large etiological heterogeneity of neuropsychiatric symptoms, which may hinder the clinical evaluation, but if using neuropsychological testing, it increases the chances of detection of cognitive and behavioral symptoms and therefore the diagnostic accuracy. The objective of the study is to estimate the prevalence of dementia and cognitive changes in neuroinfections, and characterize the co-morbid psychiatric symptoms. The sample comprised 60 patients with infection of the CNS in order to identify possible changes in performance in Mini-Mental State Examination (MMSE) and a questionnaire on activities of daily living for Pfeffer, and conduct behavioral assessment by questionnaire BEHAV - AD. By applying the MMSE and the Pfeffer questionnaire found that 20 patients (33.3% of the sample) had cognitive disorders without dementia and 23 patients were diagnosed as dementia, which is the framework neuropsychological most prevalent (38.3% of patients). If we include patients with cognitive disorders without dementia and those with dementia in one group, we obtain a total of 71.7% of the sample studied. In the psychiatric aspect, are part of apathy in 30% of cases and irritability in 43.4% of patients. Through this study, high prevalence of cognitive disorders (including dementia) between the tables of neuroinfecções, and psychiatric symptoms associated with rich, demonstrating the need for investigation of cognitive and behavioral aspects in patients with infections of the CNS.
