Avaliação de um programa de intervenção de habilidades sociais educativas parentais: um estudo-piloto

Estudos têm apontado relações entre déficits de habilidades sociais educativas de pais e problemas de comportamento de seus filhos. Nesse sentido, esta pesquisa visa a descrever os efeitos de um procedimento de intervenção com pais, o qual pretendeu promover suas habilidades sociais educativas. Participaram dois pais e sete mães, que elegeram o filho com o qual descreveram ter maiores dificuldades de relacionamento. Para a avaliação: 1) das dificuldades dos pais, foi utilizada uma entrevista estruturada, e 2) dos procedimentos de intervenção, foram utilizados: a) questionário de habilidades sociais educativas parentais (QHSE-P) e b) inventário de habilidades sociais (IHS-Del Prette). Os resultados das comparações pré e pós-intervenção do IHS-Del Prette mostraram aumento no escore dos grupos; as comparações do QHSE-P apontaram aquisições de diversas habilidades sociais educativas: expressar sentimentos positivos, agradecer elogios, dizer não e negociar limites. Discute-se a necessidade de procedimentos de promoção de habilidades sociais educativas para ampliar o repertório social parental.

Atividades preventivas realizadas pelos cirurgiões-dentistas do PSF de Natal-RN

Family Health Program (FHP) presents itself as a restructured model on basic cares besides having prevention practices and promotion in health as essential parts. According to that, the purpose of this study is to perceive which prevention practices in oral health are accomplished by the dentists from the FHP of Natal-RN as well as the way they have been developed, the knowledge basis to execute the procedure and the use of evaluation instruments by the dentists and by the Oral Health Co-Ordinator. A list of dentists participating on the FHP of Natal in March, 2006 (n= 91) was obtained so it was possible to formulate a structured interview. After excluding those with less than six months attending to the program, and considering the loss, eighty dentists got to be interviewed. It had questions about individual and group preventive procedures, sources of basement to develop the activities and to verify the impact and evaluation instruments. Besides that, an interview was made with the Oral Health Co-Ordinator about the evaluating process and the existence of a protocol as well as about document analysis in the Ambulatory Informations System Unique Health System (AIS-UHS), Information of Basic Care System and Pact of Recorder. The main individual activities consist on Oral Hygiene Orientation (87,5%) and Fluoridization (95%). Group activities remain at scholar groups acts(91,25%) being fluoridization done by 91,25% and educative activities by 86,25% mainly through speeches (61,25%).Orientations about oral cancer were detached on the aged group (39,96%)and hypertensive and diabetic group (19,51%), as well as integration with the health team was respectively 21,93% and 39,02%. Speeches and talk rounds are the main activities for aged, hypertensive and diabetics, and are also expressive to pregnant women. For pregnant women and babies group predominate hygiene and diet orientation. About the evaluation instruments 73,75% of the dentists do not consider their existence, despite 73,75% consider that actions have impact specially due to a increase of hygiene and decrease of caries index on the children. The main sources of basement are clinical experience (42,5%) and preparative courses (33,75%), only 7,5% mentioned population need and local reality. The Oral Health Co-Ordinator related the Attention Pact Recorder and records from the AIS - UHS as evaluation source but also detached the lack of epidemiologic surveying. She mentioned the increase of supervised brushing as a positive result and detached the hardness of the professional to act inside the family and as a team. The AIS-UHS records showed that fluoridization is more used individually and the supervised brushing is predominant as a group action, besides that educative activities at the Health Establishment predominate due to actions at the community. Facing the results, it was verified the act in different groups, special attention given to scholars, as well as focus the activities on caries giving less emphasis to other oral problems. Despite that, there was no epidemiologic instruments or data of the local reality to guide the actions and to be part of the planning and evaluation process

Estudo da imunoexpressão de RANKL e OPG, do índice angiogênico (CD34) e da presença de miofibroblastos (α-SMA) em ceratocistos odontogênicos isolados e associados à síndrome de Gorlin

The odontogenic keratocysts are distinguished from other odontogenic cystic lesions by their potentially aggressive clinical behavior and association, in some cases, with Gorlin syndrome. Studies have suggested that syndrome keratocysts, in comparison with sporadic lesions, have higher growth and infiltration capacity and higher recurrence tendency. The aim of this study was to analyze, by means of immunohistochemistry, the expressions of receptor activator of nuclear factor κB ligand (RANKL) and osteoprotegerin (OPG), the angiogenic index (CD34) and the presence of myofibroblasts (α-SMA) in primary and recurrent sporadic keratocysts and in keratocysts associated with Gorlin syndrome. The sample was composed by 30 sporadic keratocysts (22 primary and 8 recurrent) and 22 syndrome keratocysts. In the epithelium and in the fibrous capsule of the lesions, the immunoexpression of RANKL and OPG was evaluated by determination of the percentage of positive cells, according to the following scores: 0 (less than 10% of positive cells), 1 (11% - 50% of positive cells), 2 (51% - 75% of positive cells) and 3 (more than 76% of positive cells). In addition, cases were classified according to the RANKL score/ OPG score ratio, as follows: RANKL > OPG, RANKL < OPG, and RANKL = OPG. The angiogenic index was analyzed by counting the microvessels immunoreactive to anti-CD34 antibody in 5 fields (200). The analysis of myofibroblasts was performed by counting the cells immunoreactive to anti-α-SMA antibody in 10 fields (400). The analysis of the expressions of RANKL and OPG in the epithelial lining and in the fibrous capsule did not reveal significant differences between groups (p > 0.05). Regarding the RANKL/ OPG ratio in the epithelial lining, most sporadic primary (54.5%) and syndrome lesions (59.1%) showed RANKL < OPG ratio and RANKL = OPG ratio, respectively (p > 0.05). With respect to the RANKL/ OPG ratio in the fibrous capsule, the majority of sporadic primary (81.8%) and sporadic recurrent lesions (75.0%) and most syndrome lesions (45.5%) showed RANKL = OPG ratio (p > 0.05). The mean number of microvessels was 69.2 in sporadic primary lesions, 67.6 in recurrent lesions, and 71.6 in syndrome lesions, with no significant differences between groups (p > 0.05). The mean number of myofibroblasts was 34.4 in sporadic primary lesions, 29.3 in recurrent lesions, and 33.7 in syndrome lesions, with no significant differences between groups (p > 0.05). In conclusion, the results of the present study suggest that the differences in the biological behavior between sporadic keratocysts and keratocysts associated with Gorlin syndrome may not be related to the expressions of RANKL and OPG, the RANKL/ OPG ratio, the angiogenic index or the number of myofibroblasts in these lesions

Expressão imuno-histoquímica da e-caderina e da ß-catenina em carcinoma epidermóide oral com e sem metástase nodal

The adhesion molecules E-cadherin and β-catenin have been studied as possible markers to distinguish carcinomas with and without metastatic potential. The objective of this research was to study the imunohistochemistry expression of the E-cadherin and β-catenin in oral squamous cell carcinoma (OSCC), aiming to contribute for the better understanding of the biological behavior of this lesion. The sample consisted of 30 cases of OSCC, being 15 of tongue and 15 of lower lip. The profile and intensity of labeling and semi quantitative analysis of the percentage of immunopositive tumoral cells in membrane for E-cadherin and β-catenin had been related with the anatomical localization of the lesion, the presence or not of nodal metastasis and the histological grade of malignancy in the invasive front area of the tumor. It was registered the presence or not of cytoplasmic and nuclear labeling of the β-catenin. The results had been submitted to the statistical analysis, being used the Mann-Whitney Test, the Fisher Test and the Spearman Correlation Coefficient (α=0, 05). The results showed that the expression in membrane for E-cadherin and β-catenin was, predominantly, the heterogeneous profile in the lower lip and tongue carcinomas, as well as in the cases with and without nodal metastasis. It was not observed significant statistical difference between expression profile and amount of immunopositive cells for E-cadherin, β-catenin and the anatomical localization of the lesion and for the presence or not of nodal metastasis. However, there was significant difference of the reduced expression of these proteins with the high score of malignancy. It was verified that the expression of the β-catenin in cytoplasm was present in 22 (73.33%) of the 30 analyzed cases, and 6 cases (20%) showed nuclear expression. The statistical analysis detected significant association between the expression of the β-catenin in the cytoplasm with the histological grade of malignancy, being this molecule more frequently present in the cytoplasm in the cases of high score of malignancy. It was concluded that the reduced immunoexpression of these proteins in membrane can be related with the lowest cellular differentiation, as well as with the pattern of invasion in nests and isolated cells, demonstrated in the cases of OSCC with high histological grade of malignancy

Perfil eletroforético das proteínas séricas de serpentes Crotalus durissus terrificus (cascavel) criadas em cativeiro

As serpentes peçonhentas dos gêneros Bothrops e Crotalus têm sido mantidas em cativeiro visando à extração de venenos para a produção de imunobiológicos. O conhecimento da fisiologia desses animais e as alterações na concentração de proteínas e suas frações séricas são importantes para a identificação precoce de importantes enfermidades que cursam com estados de hipoproteinemia e hiperproteinemia. O objetivo do trabalho foi determinar a concentração de proteína total e o perfil eletroforético das proteínas séricas de serpentes Crotalus durissus terrificus (cascavel) criadas em cativeiro. Foram colhidas amostras de sangue da veia coccígea ventral de 21 serpentes adultas e sadias, divididas em dois grupos: Grupo 1 de 12 machos com peso médio de 588,89±193,55g, e Grupo 2 de nove fêmeas com peso médio de 708,33±194,04g. A proteína total sérica foi determinada pelo método de refratometria e a eletroforese em gel de agarose. Obtiveram-se valores da proteína total sérica (g/dL) de 4,51±0,50 para machos e de 4,82±0,72 para fêmeas, e para machos e fêmeas de 4,64±0,61. Foram identificadas pela eletroforese quatro frações protéicas (g/dL): albumina, a, b, g-globulinas e calculada a relação albumina:globulina. As serpentes fêmeas apresentaram maiores valores para as variáveis, albumina e para a relação albumina/globulina (AG) diferindo significativamente (P<0,05) do grupo de machos, porém sem significado clínico.

Hibridização reversa e sequenciamento na genotipagem do vírus da hepatite C

INTRODUÇÃO: Os métodos de genotipagem do vírus da hepatite C têm sido muito discutidos. O objetivo deste trabalho foi comparar as metodologias de hibridização reversa e sequenciamento direto para a genotipagem do vírus da hepatite C. MÉTODOS: Noventa e uma amostras de plasma de pacientes assistidos na Faculdade de Medicina de Botucatu da Universidade Estadual Paulista foram utilizadas. A genotipagem por hibridização reversa foi realizada utilizando o kit comercial INNO-LiPA® v.1.0. O sequenciamento direto foi efetuado em sequenciador automático utilizando protocolos in house. RESULTADOS: A genotipagem por sequenciamento direto mostrou-se eficiente na resolução dos resultados inconclusivos pelo kit comercial. O kit mostrou resultados errôneos em relação à subtipagem viral. Além disso, a genotipagem por sequenciamento direto revelou um erro do kit com relação à determinação genotípica questionando a eficiência do método também para a identificação do genótipo viral. CONCLUSÕES: A genotipagem realizada por meio de sequenciamento direto permite uma maior acurácia na classificação viral quando comparada à hibridização reversa.

Actinic cheilitis and squamous cell carcinoma of the lip: clinical, histopathological and immunogenetic aspects

Queilite actínica é a principal lesão pré-neoplásica do lábio. O carcinoma espinocelular do lábio é incluído nas estatísticas brasileiras junto com os cânceres de boca e, em conjunto, somam 40% dos cânceres de cabeça e pescoço. Há certo desconhecimento médico e odontológico em geral quanto aos fatores relacionados à carcinogênese e à progressão de tumores de boca. Genes de supressão tumoral e proteínas regulatórias de proliferação celular exercem papel na evolução da queilite actínica para carcinoma espinocelular e no comportamento biológico deste. O conhecimento de marcadores de diagnóstico e prognóstico e sua investigação têm utilidade no acompanhamento de tais pacientes.

Educação permanente em saúde: uma estratégia para a formação dos agentes comunitários de saúde

Este artigo teve por objetivo descrever e analisar o processo de educação dos Agentes Comunitários da Saúde (ACS) utilizado pelos enfermeiros na Estratégia Saúde da Família. Trata-se de uma pesquisa qualitativa, e contou com 17 sujeitos. Para a coleta de dados, utilizou-se entrevista semiestruturada, e a análise dos dados foi realizada por meio da técnica de análise de conteúdo. Identificou-se a categoria: organização do processo de educação nas unidades de saúde da família, cujas temáticas elencadas foram: enfermeiros como líderes da equipe de referência, educação permanente, metodologias tradicionais e educação centrada nas necessidades dos ACS. Através deste estudo, pudemos compreender que os enfermeiros têm pouco contato com a ferramenta da Educação Permanente, realizando as atividades de capacitação fundamentadas na metodologia tradicional de ensino, sendo necessário um investimento dos gestores no sentido de capacitá-los, no que se refere à educação permanente, possibilitando-lhes a atuação com os ACS.

Detecção de áreas degradadas na sub-bacia hidrográfica do rio taperoá/pb, utilizando parâmetros físicos dos sensores modis/terra e tm/landsat

This study includes the results of the analysis of areas susceptible to degradation by remote sensing in semi-arid region, which is a matter of concern and affects the whole population and the catalyst of this process occurs by the deforestation of the savanna and improper practices by the use of soil. The objective of this research is to use biophysical parameters of the MODIS / Terra and images TM/Landsat-5 to determine areas susceptible to degradation in semi-arid Paraiba. The study area is located in the central interior of Paraíba, in the sub-basin of the River Taperoá, with average annual rainfall below 400 mm and average annual temperature of 28 ° C. To draw up the map of vegetation were used TM/Landsat-5 images, specifically, the composition 5R4G3B colored, commonly used for mapping land use. This map was produced by unsupervised classification by maximum likelihood. The legend corresponds to the following targets: savanna vegetation sparse and dense, riparian vegetation and exposed soil. The biophysical parameters used in the MODIS were emissivity, albedo and vegetation index for NDVI (NDVI). The GIS computer programs used were Modis Reprojections Tools and System Information Processing Georeferenced (SPRING), which was set up and worked the bank of information from sensors MODIS and TM and ArcGIS software for making maps more customizable. Initially, we evaluated the behavior of the vegetation emissivity by adapting equation Bastiaanssen on NDVI for spatialize emissivity and observe changes during the year 2006. The albedo was used to view your percentage of increase in the periods December 2003 and 2004. The image sensor of Landsat TM were used for the month of December 2005, according to the availability of images and in periods of low emissivity. For these applications were made in language programs for GIS Algebraic Space (LEGAL), which is a routine programming SPRING, which allows you to perform various types of algebras of spatial data and maps. For the detection of areas susceptible to environmental degradation took into account the behavior of the emissivity of the savanna that showed seasonal coinciding with the rainy season, reaching a maximum emissivity in the months April to July and in the remaining months of a low emissivity . With the images of the albedo of December 2003 and 2004, it was verified the percentage increase, which allowed the generation of two distinct classes: areas with increased variation percentage of 1 to 11.6% and the percentage change in areas with less than 1 % albedo. It was then possible to generate the map of susceptibility to environmental degradation, with the intersection of the class of exposed soil with varying percentage of the albedo, resulting in classes susceptibility to environmental degradation
