IgG recognizing 21-24 kDa and 30-33 kDa tachyzoite antigens show maximum avidity maturation during natural and accidental human toxoplasmosis

We describe the avidity maturation of IgGs in human toxoplasmosis using sequential serum samples from accidental and natural infections. In accidental cases, avidity increased continuously throughout infection while naturally infected patients showed a different profile. Twenty-five percent of sera from chronic patients having specific IgM positive results could be appropriately classified using exclusively the avidity test data. To take advantage of the potentiality of this technique, antigens recognized by IgG showing steeper avidity maturation were identified using immunoblot with KSCN elution. Two clusters of antigens, in the ranges of 21-24 kDa and 30-33 kDa, were identified as the ones that fulfill the aforementioned avidity characteristics.

Gamma 60Co DL50/30 of Biomphalaria glabrata (Say, 1818)

The variation of resistance to 60Co gamma-rays of Biomphalaria glabrata was studied. A population of 480 mollusks was observed during 30 days - distributed in 8 groups of snails isolated and 8 groups of snails in colonies - after exposure (30 snails per group per dose) to increasing doses of gamma radiation. Doses of 10, 20, 40, 60, 80, 160, 320 and 640 Gy from a Gamma-cell 60Co irradiator, were applied to the test groups and two groups control (non-irradiated) of snails - isolated and colony - were kept apart. After have been exposed, the snails were drew back to the aquaria where they were maintained before. The survival was estimated on a daily score of the alive animals in each group-dose, starting after the irradiation exposure day. As a result, the survival self-fertilization forms (DL50/30 = 218.2 Gy) was found greater than in cross-fecundation forms. These data point to a low radio-resistance on the cross-fertilization forms - the sexual reproductive form - which is most found in nature. The lower radio-resistance of the cross-fertilization forms suggests the presence of some sex-linked hormonal factor related to this phenomenon.

Study of 30 cases of histoplasmosis observed in the Mato Grosso do Sul State, Brazil

Thirty cases of histoplasmosis observed at the University Hospital of the Federal University of Mato Grosso do Sul (HU-UFMS) from January 1998 to December 2005 are reported. Most (83.3%) of the patients were men, average 33.4 years old, 63.3% of them were born and living in Mato Grosso do Sul and 83.3% presented AIDS as an underlying disease. In almost all cases (96.7%) the disease occurred in its disseminated form and the most frequent clinical manifestations were: fever (83.3%), weight loss (70.0%), cough (63.3%), hepatomegaly and splenomegaly (40.0%), and lymph node enlargement (36.7%). The laboratory diagnosis was obtained in 29 patients by isolation of Histoplasma capsulatum from various clinical specimens cultivated in Sabouraud dextrose and brain heart infusion agar and in 16 patients the fungus was observed by direct microscopy of Giemsa-stained smears. The observed mortality was 40%. This is the first report in the literature of the occurrence of histoplasmosis in Mato Grosso do Sul State.

Avaliação da tolerância e nefrotoxicidade do antimonial pentavalente administrado na dose de 40mg Sb v/kg/dia, de 12/12h, por 30 dias na forma cutaneo-mucosa de leishmaniose

Foi avaliada a função renal de 11 pacientes com leishmaniose cutâneo-mucosa tratados com antimonial pentavalente na dose de 40mg SbV/kg/dia aplicada de 12/12 horas, em esquema contínuo, durante trinta dias. No estudo, um paciente apresentou insuficiência renal reversível e dois desenvolveram alterações enzimáticas hepáticas e eletrocardiográficas sendo o esquema terapêutico interrompido. Nos demais pacientes observou-se efeitos nefrotóxicos tais como diminuição da taxa de filtração glomerular, diminuição da capacidade de concentração urinária, avaliada por um jejum hídrico de 16 horas e aumento na fração de excreção de sódio. No exame do sedimento urinário observou-se um aumento no número de leucócitos e cilindros. Os resultados encontrados neste estudo sugerem que o tratamento com antimonial pentavalente na dose de 40mg SbV/kg/dia foi menos tolerado em virtude de seus efeitos tóxicos, não parecendo apresentar índice de cura superior ao esquema atualmente preconizado de 20mg SbV/kg/dia.

Dura mater mitral and tricuspid bioprostheses: 30 years of follow-up

PURPOSE: The dura mater bioprosthesis was developed in the Department of Cardiopneumology of the Hospital das Clínicas of the University of São Paulo Medical School in 1971. Here, we present the clinical results of the dura mater bioprosthesis over 30 years of follow-up. METHODS: We studied 70 consecutive patients who underwent mitral or tricuspid valve replacement with a dura mater bioprosthesis between January 1971 and August 1972. RESULTS: The early mortality was 10% (7 patients). The follow-up was 87% complete (9 patients were lost to follow-up). Two patients were alive and asymptomatic 30 years after valve replacement; 33 patients underwent reoperations due to valve dysfunction, and 19 died during the follow-up period. At 30 years, the actuarial survival was 49.2 ± 8.6%; freedom from rupture, 27.0 ± 10.2%; freedom from calcification, 78.8 ± 8.6%; and freedom from reoperation, 18.8 ± 7.5%. CONCLUSIONS: The dura mater bioprosthesis played an important role in the treatment of patients with mitral and tricuspid valve disease. The low rate of thromboembolism and the long period of follow-up without evidence of valve dysfunction, which occurred for several of our patients, are important characteristics of these bioprosthesis.

Modelo de previsão para identificar fatores de risco dos reinternamentos hospitalares em 30 dias : um estudo ao GDH 127 - insuficiência cardíaca ou choque

A representatividade do número de reinternamento hospitalares, no quadro dos custos hospitalares, deverá ser encarada como um indicador de qualidade nos serviços prestados e um objeto de estudo no que diz respeito à forma como estão a ser geridos esses serviços. Caracterizar os utentes com maior propensão a um reinternamento e identificar os fatores de risco que lhe estão associados torna-se, pois, pertinente, pois só assim, se poderá, no futuro, desenvolver uma atuação proativa com o objetivo primeiro de uma redução de custos sem colocar, no entanto, em causa a qualidade dos serviços que as entidades hospitalares prestam aos seus utentes. O objetivo deste estudo consiste em criar um modelo preditivo, com base em árvores de decisão, que auxilie a identificar os fatores de risco dos reinternamentos em 30 dias relativos ao Grupos de Diagnóstico Homogéneo (GDH) 127 - Insuficiência cardíaca e/ou choque, de forma a auxiliar as entidades prestadoras de cuidados de saúde a tomar decisões e atuar atempadamente sobre situações críticas. O estudo é suportado pela base de dados dos Grupos de Diagnóstico Homogéneos, a qual, possui informação sobre o utente e sobre o seu processo de internamento, nomeadamente, o diagnóstico principal, os diagnósticos secundários, os procedimentos realizados, a idade e sexo do utente e o destino após a alta. Pode concluir-se após estudo, que as taxas de reinternamentos têm vindo a aumentar nos últimos anos, que a população idosa insere-se no universo sujeito ao maior risco de reinternamento e que além do diagnóstico principal, a existência de comorbidades representa um papel importante no incremento do risco, nomeadamente, quando são diagnosticadas em simultâneo doenças renais, diabetes mellitus ou doenças isquémicas crónicas do coração (NCOP).

Validation of the Portuguese Version of EHP-30 (The Endometriosis Health Profile-30)

Introduction: Endometriosis Health Profile Questionnaire-30 is currently the most used questionnaire for quality of life measurement in women with endometriosis. The aim of this study is to evaluate the psychometric properties and to validate the Portuguese Endometriosis Health Profile Questionnaire-30 version. MATERIAL AND METHODS A sequential sample of 152 patients with endometriosis, followed in a Portugal reference center, were asked to complete a questionnaire on social and demographic features, the Portuguese version of the Endometriosis Health Profile Questionnaire-30 and of the Short Form Health Survey 36 Item â version 2. Appropriate statistical analysis was performed using descriptive statistics, factor analysis, internal consistency, item-total correlation and convergent validity. RESULTS Factorial analysis confirmed the validity of the five-dimension structure of the Endometriosis Health Profile Questionnaire-30 core questionnaire, which explained 83.2% of the total variance. All item-total correlations presented acceptable results and high internal consistency, with Cronbach's alpha ranging between 0.876 and 0.981 for the core questionnaire and between 0.863 and 0.951 for the modular questionnaire. Significant negative associations between similar scales of Endometriosis Health Profile Questionnaire-30 and Short Form Health Survey 36 Item â version 2 were demonstrated. Data completeness achieved was high for all dimensions. The emotional well-being scale in the core questionnaire and the infertility scale in the modular section had the highest median scores, and therefore the most negative impact on the quality of life of participating women. DISCUSSION The test-retest reliability and responsiveness of the questionnaire should be evaluated in future studies. CONCLUSION The present study demonstrates that the Portuguese version of the Endometriosis Health Profile Questionnaire-30 is a valid, reliable and acceptable tool for evaluating the health-related quality of life of Portuguese women with endometriosis.

Right ventricular structure and function as possible determinants of surgical outcome 30 years after repair of tetralogy of Fallot

OBJECTIVE: To identify the variables that may be involved in the persistence of symptoms (functional class II, III, or IV vs. I) in patients being followed up for 30 years after surgical repair of tetralogy of Fallot. METHODS: Fifty-three patients (27 women), who underwent corrective surgery for tetralogy of Fallot between 1960 and 1970, were studied. Their ages ranged from 7 months to 26 years. At the end of follow-up, 13 patients were asymptomatic and the remaining were in functional class II (N=24), III (N=15), and IV (N=1). To differentiate asymptomatic from symptomatic patients, the following variables were analyzed: age at surgery, need for widening the pulmonary ring and trunk, need for a second (2nd OP) or 3rd operation, residual defect of the interventricular septum, residual regurgitation of the pulmonary valve, systolic gradient through the right ventricular outflow tract, right ventricular dilation or hypertrophy (RVH), cardiothoracic index (CTI), right and left ventricular ejection fraction (RVEF/LVEF), and arrhythmias. RESULTS: The univariate analysis showed an association between the presence of symptoms and the 2nd OP (P=0.03), an increase in the CTI (P=0.0001), moderate to severe RVH (P=0.002), and dilation (P=0.0003). In the logistic regression model, the combination of the 2nd OP (P=0.008), the RVH (P=0.002), and the reduction in RVEF (P=0.01) determined the presence of symptoms. CONCLUSION: Despite the surgical treatment, right ventricular remodeling and performance were the major determinants in the late follow-up of tetralogy of Fallot.

Síndrome metabólica em pacientes submetidos à cirurgia de revascularização miocárdica: prevalência e marcador de morbi-mortalidade no período intra-hospitalar e após 30 dias

OBJETIVOS: Comparar a morbi-mortalidade de pacientes com e sem síndrome metabólica (SM) (de acordo com a I Diretriz Brasileira de Diagnóstico e Tratamento da SM) submetidos à cirurgia de revascularização miocárdica (RM), na fase hospitalar e após 30 dias. MÉTODOS: Foram avaliados 107 pacientes submetidos à RM sem procedimentos associados, no período de agosto a outubro de 2005, sendo 74 (69,2%) portadores de SM. Os critérios de evolução intra-hospitalar foram: fibrilação atrial aguda (FA), ventilação mecânica prolongada (VM), necessidade de transfusão de hemoderivados, número de horas na UTI, período de internação (em dias), infecção respiratória e de ferida operatória, e óbito. Em 30 dias avaliou-se a combinação de eventos como a necessidade de re-internação, infecção de ferida operatória e óbito. RESULTADOS: A média de idade foi 60,6±9,7 e o grupo com SM apresentou maior índice de massa e superfície corpórea e maior prevalência de diabete. Não houve diferença estatisticamente significante na ocorrência dos eventos intra-hospitalares como FA (15,2% x 16,2%), VM (3,0% x 2,7%), quantidade de unidades de hemoderivados utilizados (3,2±2,7 x 2,6±2,9), tempo de permanência na UTI (53,7±27,3 x 58,9±56,5), tempo de permanência hospitalar (9,2±8,7 x 8,5±8,5), infecção respiratória (6,1% x 2,7%), infecção de ferida operatória (3,0% x 5,4%) e taxa de mortalidade (3,0% x 0,0%). A ocorrência de eventos combinados em 30 dias foi semelhante nos dois grupos (12,2% x 20,3%, p = NS). CONCLUSÃO: Portadores de SM não apresentaram aumento da morbimortalidade quando submetidos à cirurgia de RM, porém apresentam tendência à maior ocorrência de infecção em ferida operatória.
