RESUMO
FIV e FeLV são retrovírus associados principalmente com neoplasias. Dois testes rápidos são disponibilizados no Brasil para o diagnóstico dessas infecções: um kit de imunocromatografia de fluxo bidirecional (SNAP® Combo IDEXX) e um kit de imunocromatografia de fluxo lateral unidirecional (ALERE/BIONOTE Anigen Rapid). O objetivo deste estudo foi comparar o teste SNAP® com o teste ALERE. Amostras de sangue de 178 gatos foram testadas utilizando-se ambos os kits. A reação em cadeia de polimerase em tempo real (qPCR) foi empregada como método confirmatório para todos os resultados. O teste SNAP® apresentou sensibilidade e especificidade de 100% para FIV; a sensibilidade e a especificidade do teste ALERE foram de 96,15% e 98,68%, respectivamente. A sensibilidade e a especificidade para o FeLV foram de 93,02% e 96,30% para o teste SNAP® e de 90,70% e 97,78% para o teste ALERE. Ainda em relação ao FeLV, três amostras com resultado positivo na qPCR obtiveram resultado falso-negativo em ambos os testes. Não houve diferença estatisticamente significante entre os métodos. Considerando a qPCR como padrão-ouro, o teste SNAP® apresentou maior sensibilidade e especificidade para o FIV, e o teste ALERE apresentou maior especificidade para o FeLV. Os resultados mostraram uma boa correlação entre os testes.(AU)
FIV and FeLV are Retrovirus associated mainly with feline neoplasms. Two point-of-care tests are commercially available in Brazil for diagnosis of these infections: a bidirectional flow immunochromatography kit (IDEXX SNAP ® Combo) and a lateral unidirectional flow immunochromatography kit (ALERE/BIONOTE Anigen Rapid). The aim of this study was to compare SNAP ® and ALERE tests. Blood samples obtained from 178 cats were evaluated using both tests. Quantitative real-time polymerase chain reaction (qPCR) was used as confirmatory test for all samples. The sensitivity and specificity of SNAP ® test was 100% for FIV, and for ALERE test was 96.15% and 98.68%, respectively. The sensitivity and specificity for FeLV was 93.02% and 96.30% for SNAP ® test and 90.70% and 97.78% for ALERE test. Three samples with a qPCR positive result for FeLV obtained a false negative result in both SNAP ® and ALERE tests. There was no statistically significant difference between the two methods. Considering qPCR as gold standard method, the SNAP® test showed higher sensitivity and specificity for FIV, and the ALERE test presented higher specificity for FeLV. The results showed good agreement among the tests.(AU)

OBJECTIVES: The main purpose of this study was to evaluate the radiographic aspect of the healing of extraction sockets filled with a xenogenic graft material (Gent-tech). METHODS: Thirty-nine patients ranging in age from 15 years to 25 years with bilateral impacted mandibular molars were chosen based on bilateral mandibular similarities. After tooth extraction, the socket was filled with the graft. The opposite site was left to heal naturally and served as a control. The experimental and control sites were chosen randomly. Bone density and crest healing were evaluated on digital radiographs taken immediately, 2 months and 6 months after surgery. The respective pixels values obtained with the Digora software were compared statistically. RESULTS: The results showed a significant decrease in the distance from the cemento-enamel junction to the alveolar bone crest, but no difference was found between the control and experimental groups. Bone density increased significantly, and there was difference between experimental and control groups. CONCLUSION: The analysed parameters observed by the authors were similar to those of the control group, suggesting xenogenic graft being an acceptable material and a graft option.

OBJECTIVES: To identify the contour and pixel grey levels of simple bone cyst (SBC) and odontogenic keratocyst (OKC) images that might contribute to differentiating between the two lesions. METHODS: Panoramic radiographs of 32 SBC and 20 OKC were digitized and analysed by six examiners. The contours of the images were classified as indistinct, distinct without a sclerotic border, and distinct with a sclerotic border. The presence or absence of scalloping and the pixel grey levels of the radiolucent part of the images were also determined. RESULTS: The sclerotic border was more frequent in the OKC, especially in the posterior segment (P = 0.0301). The presence of scalloping was more frequent in the superior segment of the SBC (P = 0.0295). The pixel values were higher in the OKC than in the SBC images (P = 0.00134). CONCLUSIONS: Details about the contour and pixel grey levels of OKC and SBC assist in the diagnosis of these lesions.

Prison populations are at increased risk of both human immunodeficiency virus (HIV) and Mycobacterium tuberculosis infections, but among female inmates information on such risks remains scarce, especially in developing countries. Between October 1992 and November 1993, 350 women incarcerated at a prison in São Paulo, Brazil, were prospectively evaluated for HIV and M. tuberculosis infection and disease. Among them, 87 (25%) were HIV seropositive, and 20 (5.7%) had tuberculosis (TB). During the incarceration period, the purified protein derivative test conversion rate was 29% for HIV-positive and 32% for HIV-negative women. However, the incidence of TB was 9.9 per 100 person-years for HIV-positive and 0.7 per 100 person-years of incarceration for HIV-negative women (p < 0.0001). A multivariate analysis indicated that HIV infection (p < 0.0001) and incarceration time < 12 months (p < 0.05) were each associated with TB. These findings indicate that new transmissions of M. tuberculosis infection are common among female inmates and that HIV-infected women are more likely to acquire active disease during the first 12 months of incarceration. Because of their role in childbearing and care female inmates are an important potential source of transmission of M. tuberculosis, and new strategies to control the spread of TB in prisons need to be developed.

Generation of epidemiological data on perinatally-transmitted infections is a fundamental tool for the formulation of health policies. In Brazil, this information is scarce, particularly in Northeast, the poorest region of the country. In order to gain some insights of the problem we studied the seroprevalence of some perinatally-transmitted infections in 1,024 low income pregnant women in Salvador, Bahia. The prevalences were as follow: HIV-1 (0.10%), HTLV-I/II (0.88%), T.cruzi (2.34%). T.pallidum (3.91%), rubella virus (77.44%). T.gondii IgM (2.87%) and IgG (69.34%), HBs Ag (0.6%) and anti-HBs (7.62%). Rubella virus and T.gondii IgG antibodies were present in more than two thirds of pregnant women but antibodies against other pathogens were present at much lower rates. We found that the prevalence of HTLV-I/II was nine times higher than that found for HIV-1. In some cases such as T.cruzi and hepatitis B infection there was a decrease in the prevalence over the years. On the other hand, there was an increase in the seroprevalence of T.gondii infection. Our data strongly recommend mandatory screening tests for HTLV-I/II, T.gondii (IgM), T.pallidum and rubella virus in prenatal routine for pregnant women in Salvador. Screening test for T.cruzi, hepatitis and HIV-1 is recommended whenever risk factors associated with these infections are suspected. However in areas with high prevalence for these infections, the mandatory screening test in prenatal care should be considered.

BACKGROUND: Little is known about the prevalence of and risk factors for human T-lymphotropic virus type I and type II (HTLV-I, HTLV-II) infections in Brazil. STUDY DESIGN AND METHODS: Sera from 17,063 healthy Brazilian donors were screened by enzyme-linked immunosorbent assay for antibody to HTLV-I/II between August 1991 and July 1993. Repeatedly reactive samples were confirmed by Western blot, and discrimination between HTLV-I and HTLV-II was made by polymerase chain reaction or synthetic peptide enzyme-linked immunosorbent assay. A univariate analysis was performed on demographic and serologic data. RESULTS: HTLV-I infection was demonstrated in 83 percent of the 30 donors with reactive serologic tests (0.15% of the total tested [17,063]; 95% CI, 0.09-0.20) and HTLV-II infection in 17 percent (0.03% of the total tested [17,063]; 95% CI, 0.01-0.05). HTLV-I-positive donors were more likely than reference groups to be of Asian ethnicity (odds ratio [OR] 15.1; reference group: whites), more than 50 years old (OR 4.2; reference group: 20-29 years old), and positive for antibody to hepatitis C virus (anti-HCV) (OR 21.8) or to hepatitis B core (antigen) (anti-HBc) (OR 5.7). HTLV-II showed a significant association with anti-HCV (OR 75.2) and anti-HBc (OR 21.8). Eleven of the 25 HTLV-I-positive donors were counseled. Family origin in endemic areas of Japan (n = 4), prior blood transfusion (n = 3), or sexual contact with prostitutes (n = 1) were the risk factors reported by 8 donors. In 3 white men, no risk factors could be identified. CONCLUSION: Both HTLV-I and HTLV-II occur among Brazilian blood donors. HTLV-I is associated with Asian ethnicity, greater age, and the presence of anti-HCV and anti-HBc. Three HTLV-I-positive donors had a history of blood transfusion, which emphasizes the need for HTLV-I/II screening in Brazil.

In order to investigate the sexual transmission of the Hepatitis C Virus (HCV), the prevalence of specific antibodies in populations at high and low risk for sexually transmitted diseases (STDs) was evaluated. The population at low risk for STDs was composed of persons who voluntarity donated blood at the Hospital Universitário Clementino Fraga Filho (HUCFF) between July and November, 1990 (n = 2494). The population at high risk for STDs was drawn from an ongoing study on the natural history of Human Immunodeficiency Virus (HIV) infection (n = 210, 187 with sexual risk factors for HIV infection). All samples were screened using a first generation ELISA. Repeat reactive samples were then tested in a second generation RIBA. For all ELISA positive samples, two sex and age-matched ELISA negative controls were selected. Data pertaining to the presence of antibodies to the Hepatitis B core antigen (anti-HBC antibodies) and to Treponema pallidum were abstracted from the medical records. The prevalence of RIBA 2 confirmed HCV infection among the blood donors was 2.08%, which is well above the reported prevalence in similar populations from developed western countries. Among the HIV infected homosexuals, the encountered prevalence was 7.96% (p < 0.0005). For the whole group with sexually acquired HIV infection, the prevalence was 8.02% (p < 0.000005). Anti-HBc antibodies were more frequently present in anti-HCV RIBA-2 confirmed positive blood donors than in controls (p < 0.001). 33.3% of the HCV-positive blood donors and 11.04% controls were found to be anti-HBc positive (p < 0.0005). As for the FTA-ABs, 17.6% HCV-positive donors and 4,9% controls were positive (p < 0.01). 5.9% samples from blood donors were both anti-HBc and FTA-ABS positive, whereas none of the controls reacted in both tests (p < 0.05). The association between HCV, Hepatitis B infection and syphilis in individuals at low risk for parenterally transmitted diseases suggests that sexual transmission contributes to the maintenance of the endemicity of HCV in the local population

PIP: Hepatitis C virus (HCV) has an etiological role in post-transfusional Non-A Non-B Hepatitis, cirrhosis, and hepatoma. Studies have revealed an high prevalence of anti-HCV antibodies in hemophiliacs, IV drug users, and other groups at risk for parenterally transmitted infections. The authors report findings from their investigation into the sexual transmission of HCV. The prevalences of antibodies to HCV, the hepatitis B core (HBc) antigen, and to Treponema pallidum were assessed among groups of individuals at high and low risk for sexually transmitted diseases (STD). The population at low risk for STDs was comprised of 2494 volunteer blood donors at the Hospital Universitario Clementino Fraga Filho (HUCFF) over the period July-November 1990. The population at high risk for STDs was comprised of 187 adults consecutively enrolled between September 1990 and January 1991 in a cohort study of the natural history of HIV infection. Sera were screened with a first generation HCV ELISA test, with repeat reactive samples further analyzed using a second generation recombinant immunoblot confirmatory test (RIBA-2). Data on the presence of antibodies to HBc, VRDL, and HIV were abstracted from the Blood Bank records. Antibody testing against Treponema pallidum was conducted among HCV-ELISA positive blood donors and their controls using FTA-ABs. 2.08% of blood donors were infected with HCV, 7.96% of the HIV-infected homosexuals, and 8.02% of the whole group with sexually acquired HIV infection. Anti-HBc antibodies were more frequently present in anti-HCV RIBA-2 confirmed positive blood donors than in controls. 33.3% of the HCV-positive blood donors and 11.04% of controls were found to be anti-HBc positive. 17.6% of HCV-positive donors and 4.9% of controls yielded positive FTA-ABs results. 5.9% of samples from blood donors were both anti-HBc and FTA-ABs positive, while none of the controls reacted in both tests. The association between HCV, hepatitis B infection, and syphilis in individuals at low risk for parenterally transmitted diseases suggests that sexual transmission contributes to the maintenance of the endemicity of HCV in the local population.

From an index case of tropical spastic paraparesis (TSP), four generations of a Brazilian family of African descent were investigated for human T-lymphotropic virus type I (HTLV-I) infection and its association with neurologic manifestations, as well as the possible routes of transmission. Thirty-two individuals were studied. Polymerase chain reaction (PCR) was used for confirmation of infection. HTLV-I infection was demonstrated in eight subjects (the index case, 6 of 24 blood relatives, and 1 of 7 spouses). The index case and two blood relatives had TSP, whereas subclinical neurologic disturbances were present in three other blood relatives and one spouse. Another member of the family, who had died before this study, had had diagnoses of spastic paraparesis of unknown etiology and small-cell lymphoma. Only 1 of 8 infected individuals was neurologically intact. Of 5 vertically infected individuals, 4 had been breast-fed for long periods (1-2 years). These are the first reported cases of PCR-proved HTLV-I-associated spastic paraparesis in Brazil.

Analisou-se o conteudo celular dialitica drenada da cavidade peritoneal, durante dialise peritoneal, em cinco pacientes com insuficiencia renal cronica. As celulas obtidas mostraram sempre viabilidade maior que 90%, e foram analisadas pelo metodo de Giemsa e metodos citoquimicos para esterase acida e mieloperoxidase. No inicio do procedimento dialitico, observou-se um pico celular composto basicamente por fagocitos mononucleares, linfocitos e eosinofilos. Em tres dos cincos pacientes, apos grande reducao do numero de celulas drenadas da cavidade peritoneal, observou-se um segundo pico celular composto principalmente por neutrofilos, com desaparecimento de outros tipos celulares. Este segundo pico celular nao foi observado em outros dois pacientes, o que sugere a existencia de diferentes padroes de migracao leucocitaria para cavidade peritoneal
