Conhecimento contraceptivo no puerpério precoce e seu uso efetivo após seis meses

Objetivo: Avaliar o conhecimento sobre métodos anticoncepcionais em mulheres no puerpério, bem como analisar a escolha e seu uso efetivo decorrido seis meses do parto. Método: Estudo prospectivo, transversal, realizado por entrevistas no puerpério precoce e após seis meses, com 107 mulheres internadas que aceitaram participar do estudo após a leitura do consentimento livre e esclarecido. Avaliaram-se os indicadores socioeconômicos, o conhecimento em anticoncepção, a orientação recebida, a oferta e uso de contraceptivos após seis meses do parto. Resultados: Os métodos anticoncepcionais mais conhecidos de forma espontânea foram a pílula (89%) e o condom masculino (65%). O DIU com hormônio foi o menos lembrado espontaneamente. Perto de 95% das puérperas referiram desejar evitar nova gravidez. Os métodos mais escolhidos foram a pílula (24%) e a ligadura tubária (18%). Ao se perguntar sobre o interesse em outros métodos contraceptivos após o questionário, 48% demonstraram interesse, sendo o mais citado o DIU (26%). Apenas um quarto das mulheres que disseram conhecer o DIU, faria a opção pelo método. Após seis meses, apenas 47 mulheres foram contatadas, e somente 31 delas haviam recebido orientação sobre anticoncepção (em média sobre três métodos diferentes). Houve apenas uma inserção de DIU de cobre, e três mulheres estavam grávidas naquele momento. Conclusões: O conhecimento da anticoncepção pelas mulheres no puerpério foi alto e melhorou após a estimulação. A avaliação dos resultados parece indicar que a simples leitura dos métodos anticoncepcionais disponíveis contribui para a escolha por métodos não relatados espontaneamente

Change in central kinin B2 receptor density after exercise training in rats

Cardiovascular responses elicited by the stimulation of kinin B2 receptors in the IV cerebral ventricle paratrigeminal nucleus or in the thoracic spinal cord are similar to those observed during an exercise bout Considering that the kalikrein-kinin system (KKS) could act on the cardiovascular modulation during behavioral responses as physical exercise or stress this study evaluated the central B2 receptor densities of Wistar (W) and spontani ously hypertensive rats (SHR) after chronic moderate exercise Animals we re exercise-trained for ten weeks on a treadmill Afterwards systolic blood pressure decreased in both trained strains Animals were killed and the medulla and spinal cord extracted for B2 receptor autoradiography Trained animals were compared to their sedentary controls Sedentary groups showed specific binding sites for Hoe-140 (fmol/mg of tissue) in laminas 1 and 2 of the spinal cord nucleus of the solitary tract (NTS) area postrema (AP) spinal trigeminal tract (sp5) and paratrigeminal nucleus (Pa5) In trained W a significant increase (p<0 05) in specific binding was observed in the Pa5 (31 3%) and NTS (28 2%) Trained SHR showed a significant decrease in n ceptor density in lamina 2 (21 9%) of the thoracic spinal cord and an increase in specific binding in Pa5 (36 1%) We suggest that in the medulla chronic exercise could hyper stimulate the KKS enhancing their efficiency through the increase of B2 receptor density involving this receptor in central cardiovascular control during exercise or stress In the lamina 2 B2 receptor might be involved in the exercise-induced hypotension (C) 2010 Elsevier BV All rights reserved

Iron deficiency and frequency of HFE C282Y gene mutation in Brazilian blood donors

Limited data are available about iron deficiency (ID) in Brazilian blood donors. This study evaluated the frequencies of ID and iron-deficiency anaemia (IDA) separately and according to frequency of blood donations. The protective effect of the heterozygous genotype for HFE C282Y mutation against ID and IDA in female blood donors was also determined. Five hundred and eight blood donors were recruited at the Blood Bank of Santa Casa in Sao Paulo, Brazil. Haemoglobin and serum ferritin concentrations were measured. The genotype for HFE C282Y mutation was determined by polymerase chain reaction followed by restriction fragment length polymorphism analysis. The ID was found in 21 center dot 1% of the women and 2 center dot 6% of the men whereas the IDA was found in 6 center dot 8 and 0 center dot 3%, respectively. The ID was found in 11 center dot 9% of the women in group 1 (first-time blood donors) and the frequency increased to 38 center dot 9% in women of the group 3 (blood donors donating once or more times in the last 12 months). No ID was found in men from group 1; however the ID frequency increased to 0 center dot 9% in group 2 (who had donated blood before but not in the last 12 months) and 5 center dot 0% in group 3. In summary, the heterozygous genotype was not associated with reduction of ID or IDA frequencies in both genders, but in male blood donors it was associated with a trend to elevated ferritin levels (P = 0 center dot 060). ID is most frequent in Brazilian women but was also found in men of group 3.

Hepatitis D and B virus genotypes in chronically infected patients from the Eastern Amazon Basin

Hepatitis D virus (HDV) is a defective hepatotropic virus whose infectivity is dependent on hepatitis B virus (HBV). HDV super- or co-infiection leads to an increased risk of fulminant hepatitis or progression to severe chronic liver disease in HBV infected patients. The Brazilian Amazon Basin has been reported to be endemic for HBV and HDV, especially in the Western Amazon Basin. In this region, HDV infection is frequently associated with acute fulminant hepatitis with characteristic histologic features. HDV is classified into seven major clades (HDV-1 to HDV-7) and HBV is subdivided into eight genotypes (A-H). HDV and HBV genotypes have been shown to have a distinct geographic distribution. The aim of this study was to determine the HBV and HDV genotypes harbored by chronically infected patients from the Eastern Amazon Basin, Brazil. We studied 17 serum samples from HBV and HDV chronically infected patients admitted to a large public hospital (Santa Casa de Misericordia) at Belem, state of Para, Brazil, between 1994 and 2002. HDV-3 and HBV genotype A (subtype adw2) have been identified in all cases, in contrast to previous studies from other regions of the Amazon, where HBV genotype F has been found co-infecting patients that harbored HDV-3. The HDV-3/HBV-A co-infection suggests that there is not a specific interaction between HBV and HDV genotypes, and co-infection might merely reflect the most frequent genotypes found in a particular geographic area. The analysis of the carboxy-terminal region of the large hepatitis D antigen (L-HDAg), which interacts with the hepatitis B surface antigen (HBsAg) and is essential for HDV assembly, showed some diversity between the different isolates from the Eastern Amazon. This diversity is not observed among HDV-3 sequences from other South American regions. (C) 2008 Elsevier B.V. All rights reserved.

Comparison between videofluoroscopy and endoscopic evaluation of swallowing for the diagnosis of dysphagia in children

OBJECTIVE: To compare videofluoroscopy swallowing study (VFSS) with the fiberoptic endoscopic evaluation of swallowing (FEES) in children and to determine the accuracy of FEES in the diagnosis of specific swallowing disorders. STUDY DESIGN: Cross-sectional study. SETTING: Hospital da Crianca Santo Antonio, affiliated with Santa Casa de Misericordia Hospital Complex, Porto Alegre, RS, Brazil. SUBJECTS AND METHODS: FEES findings were compared to those of VFSS in 30 children. Kappa coefficients for interobserver agreement were calculated. Thereafter, these coefficients were evaluated in terms of agreement between FEES and VFSS. In addition, the sensitivity, specificity, positive predictive value, and negative predictive value of FEES were calculated for four swallowing parameters (posterior spillover, pharyngeal residues, laryngeal penetration, and laryngotracheal aspiration). RESULTS: Interobserver agreement rates greater than 70 percent were obtained for all FEES parameters analyzed, except for pharyngeal residues with puree consistency (agreement = 66.7%, K = 0.296, P = 0.091). Laryngeal aspiration and penetration yielded the best level of agreement (100%, K = 1) for the laryngeal aspiration of puree residues. CONCLUSION: The diagnostic agreement between FEES (both observers) and VFSS was low. Regarding the analyzed parameters, laryngeal penetration and aspiration yielded the highest interobserver agreement in terms of FEES, and also showed the highest specificity and positive predictive value when compared to VFSS.

Complicações intracranianas das otites médias crônicas supurativas em crianças

Apesar de sua significativa diminuição após o advento dos antibióticos, as complicações intracranianas das otites médias ainda representam uma situação de risco, uma vez que a taxa de mortalidade permanece alta, chegando a 36%. Entre as formas mais comuns estão meningite, abscesso cerebral, abscesso extradural e tromboflebite do seio lateral. Um alto índice de suspeição é fundamental para seu diagnóstico e manejo precoces. É importante a identificação de casos atípicos que podem estar mascarados pelo uso de antimicrobianos. OBJETIVO: Apresentamos seis casos de complicações intracranianas por otite média em crianças e adolescentes ocorridos no período de dois anos no Serviço de Otorrinolaringologia do Complexo Hospitalar Santa Casa (CHSC). FORMA DE ESTUDO: relato de série.

Identificação de cepas de Escherichia coli enteropatogênicas em amostras de fezes, por reação de imunofluorescência direta

Foi realizado diagnóstico etiológico de casos de diarréia aguda em 121 pacientes internados na Clínica Pediátrica do Hospital da Santa Casa de São Paulo, Brasil. Foram utilizados os métodos bacteriológico clássico e de reação de imunofluorescência direta para a identificação de cepas de Escherichia coli enteropatogênicas: para estudo da sensibilidade das cepas de Escherichia coli isoladas, a diferentes antibióticos, foi usado o método de Concentração Inibitória Minima (CIM). Dos 56 casos positivos, 89,3% correspondiam a diferentes sorotipos enteropatogênicos de Escherichia coli, quando utilizada a técnica de imunofluorescência direta. O método bacteriológico clássico revelou ainda, nos 121 casos examinados, 4 cepas de Salmonella e 2 de Shigella. No estudo da CIM verificou-se maior sensibilidade das cepas de Escherichia coli enteropatogênicas estudadas à Gentamicina e Amikacina, do que aos outros antibióticos.

Candidemia in a Brazilian tertiary care hospital: species distribution and antifungal susceptibility patterns

Recent studies have shown differences in the epidemiology of invasive infections caused by Candida species worldwide. In the period comprising August 2002 to August 2003, we performed a study in Santa Casa Complexo Hospitalar, Brazil, to determine Candida species distribution associated with candidemia and their antifungal susceptibility profiles to amphotericin B, fluconazole and itraconazole. Antifungal susceptibility was tested according to the broth microdilution method described in the NCCLS (M27A-2 method). Only one sample from each patient was analyzed (the first isolate). Most of the episodes had been caused by species other than C. albicans (51.6%), including C. parapsilosis (25.8%), C. tropicalis (13.3%), C. glabrata (3.3%), C. krusei (1.7%), and others (7.5%). Dose-dependent susceptibility to itraconazole was observed in 14.2% of strains, and dose-dependent susceptibility to fluconazole was found in 1.6%. Antifungal resistance was not found, probably related to low use of fluconazole. Further epidemiological surveillance is needed.

Candida guilliermondii as the aetiology of candidosis

Candida guilliermondii is one of the components of human microbiota. This yeast has been infrequently associated with human infections, which may be related to its low pathogenicity. The aim of this study was to provide clinical and epidemiological data for patients infected with C. guilliermondii at Santa Casa Complexo Hospitalar, Brazil. From October 1997 to October 2003, C. guilliermondii was isolated from clinical samples from 11 patients. Three patients were excluded because the isolation of the yeast represented colonisation. Specimens from the eight patients included in the study corresponded to blood (n = 5), ascitis fluid (n = 2), and oesophagus biopsy (n = 1). Three patients (37.5%) had major immunosuppressed conditions, including solid organ transplantation, AIDS, and leukaemia. Previous use of antibiotics occurred in 87.5%. Main invasive medical procedures were central venous catheter (50.0%), abdominal surgery (25.0%), and peritoneal dialysis (50.0%). No susceptibility data was obtained. Although risk factors for candidaemia were similar amongst patients infected by with C. guilliermondii or other Candida species, mortality associated with C. guilliermondii was significantly lower.

Candida esophagitis: species distribution and risk factors for infection

Although Candida albicans is the main cause of fungal esophagitis, other species such as C. tropicalis, C. krusei and C. stellatoidea have also been implicated. Several studies have identified risk factors for C. albicans esophagitis. However, data for non-C. albicans species is still sparse. The aim of this study was to determine the etiology of Candida esophagitis in our medical centre over an 18-month period. Additionally, we aimed to investigate predisposing conditions for esophageal candidosis caused by different Candida species. A total of 21,248 upper gastroscopies were performed in Santa Casa Complexo Hospitalar between January 2005 and July 2006. The prevalence of Candida esophagitis was 0.74% (n = 158). C. albicans caused the vast majority of infections (96.2%), followed by C. tropicalis (2.5%), C. lusitaniae (0.6%) and C. glabrata (0.6%). There were 81 women (51.3%) and 77 men (48.7%). No case of mixed infection occurred. Concomitant oral candidosis was documented for 10.8% (n = 17). Most of cases (55.1%) involved outpatients. Around one fifth of patients in our cohort had no identifiable risk factors for esophageal candidosis (20.8%). Since nearly all infections were caused by C. albicans we were not able to determine risk factors for esophagitis caused by other Candida species.

Reavaliação da suscetibilidade de Candida à anfotericina B: estudo comparativo com isolados de três hospitais do estado do Rio Grande do Sul

Comparou-se a suscetibilidade à anfotericina B de Candida spp isoladas de candidemias, sendo: 41 do Hospital Universitário de Santa Maria, 56 do Hospital de Clínicas de Porto Alegre e 47 da Santa Casa, Complexo Hospitalar de Porto Alegre. Os testes foram baseados no documento M27-A2 do Clinical Laboratory Standards Institute. Todavia, foram empregadas 20 concentrações de anfotericina B, variáveis entre 0,1 e 2µg/ml. Os testes foram realizados nos meios RPMI 1640 com glicose, antibiotic medium 3 e yeast nitrogen base dextrosado. O caldo antibiotic medium 3 gerou amplas faixas de concentrações inibitórias mínimas e concentrações fungicidas mínimas quando comparado aos demais. As variações de suscetibilidade entre os hospitais foram melhor detectadas no antibiotic médium 3; os isolados do Hospital Universitário de Santa Maria evidenciaram menor sensibilidade do que os da Santa Casa, Complexo Hospitalar de Porto Alegre (p < 0,05). As causas das variações de suscetibilidade não foram avaliadas mas apontam para a necessidade de vigilância da suscetibilidade a anfotericina B.

Avaliação de hansenianos tratados com esquema alternativo dose única ROM (rifampicina, ofloxacina e minociclina), após sete a nove anos

INTRODUÇÃO: Em 1997, após a realização de estudo multicêntrico, duplo cego e randomizado, em nove centros de tratamento de hanseníase na Índia, o Ministério da Saúde adotou o esquema alternativo dose única ROM para casos de lesão única, paucibacilar, sem nervo periférico afetado, índice baciloscópico negativo, em Centros de Referência da doença no Brasil. O estudo se propôs a avaliar a efetividade do esquema ROM em pacientes tratados no período de 1997 a 1999 no Serviço de Dermatologia da Santa Casa de Vitória. MÉTODOS: Foram selecionados e tratados com o esquema ROM, 54 pacientes das formas indeterminada e tuberculóide. Estes pacientes foram convocados de março a outubro de 2006 para reavaliação clínica. RESULTADOS: Vinte e nove pacientes avaliados (85,2%; IC95%: 70-100,4) estavam curados, cinco (14,7%; IC95%: 7,4-22,0) recidivaram e 20 pacientes não retornaram; porém, não havia outra notificação de reingresso ao tratamento no banco de dados da Secretaria Estadual de Saúde. CONCLUSÕES: O estudo evidenciou taxa de cura de 90,8% e taxa bruta de recidiva de 9,2%, após período de sete a nove anos da dose ROM. O tratamento alternativo ROM demonstrou melhor efetividade para lesão única menor que quatro centímetros e aparecimento há menos de cinco anos.
