Avaliação da qualidade de vida dos funcionários do cartório do 1º Ofício da cidade de Diamantino-MT através do questionário SF-36

O objetivo desta pesquisa foi analisar a qualidade de vida dos funcionários do Cartório de 1º Ofício da cidade de Diamantino, em Mato Grosso. Foi utilizada a versão brasileira do Short Form-36 (SF-36) em dez funcionários do Cartório de 1º Ofício, que colaboraram voluntariamente para a coleta da análise dos dados do questionário. O estudo obteve a análise dos oito domínios do escore do SF-36, onde pôde ser observado que o primeiro domínio, relativo à capacidade funcional, foi aquele que apresentou o maior escore, enquanto os demais domínios (D2, D3, D4, D5, D6, D7 e D8), respectivamente relacionados à saúde mental, também estão acima da metade do valor máximo esperado no escore do SF-36. O questionário SF-36 foi um instrumento adequado, de aplicação relativamente rápida e de fácil uso para a avaliação da qualidade de vida dos funcionários do Cartório de 1º Ofício, pois, na amostra estudada, os oito domínios apresentaram resultado médio entre 51,9 (menor escore = domínio 4) e 71,8 (maior escore = domínio 1).

Manifestações mucocutâneas de histoplasmose na AIDS : avaliação de 36 pacientes

Introdução: A histoplasmose é uma infecção geralmente subclínica e autolimitada em pacientes imunocompetentes. A maioria dos pacientes com HIV apresenta a forma disseminada da doença, considerada definidora de aids. As manifestações cutâneo-mucosas da histoplasmose são variadas, dificultando o diagnóstico. Métodos: Estudo retrospectivo de 24 pacientes com diagnóstico de histoplasmose, avaliados no serviço de Dermatologia do Hospital de Clínicas de Porto Alegre, de 2000 a 2003 e, prospectivamente, mais 12 pacientes, atendidos em 2004 e 2005. A análise considerou dados epidemiológicos e demográficos, bem como os parâmetros clínicos, distribuição e morfologia das lesões, contagem de células CD4+, terapia da micose e antirretroviral e se a doença foi a definidora de aids. Resultados: Vinte e seis (72%) doentes eram homens. A idade média foi 34 anos (17-58) e 16 pacientes (49%) tiveram seus diagnósticos realizados de dezembro a março, no verão. A histoplasmose foi confirmada por biópsia cutânea em 33 casos e por cultura em 23 deles. Onze pacientes recebiam antirretrovirais no momento do diagnóstico e a sua contagem de células CD4+ variou de 2 a 103 (média 29 células/mm³). Não houve diferenças significativas em relação a sexo, idade, método diagnóstico e uso de antirretrovirais entre a amostra retrospectiva e prospectiva. O número médio de lesões foi 2,7, variando de 1 a 7 tipos diferentes em um mesmo paciente. Pápulas com crosta e erosão/úlcera de mucosa foram as mais frequentes, em 64% e 58% dos pacientes, respectivamente. Uma distribuição difusa foi a mais comum, em mais de 58% dos casos. Houve uma associação significativa entre a contagem de células CD4+ e a variabilidade morfológica de lesões por paciente, sendo que um menor polimorfismo de lesões está associado a contagens mais baixas de células CD4+. Conclusão: A familiaridade com as manifestações dermatológicas da histoplasmose é importante para uma maior suspeição tanto da doença, quanto do próprio HIV. Pápulas com crostas difusas e erosão/úlcera de mucosa, no verão, em pacientes com aids e contagem de células CD4+ menor do que 50 células/ mm³ são achados muito sugestivos de histoplasmose. Porém, é de suma importância a realização de exames complementares para a exclusão dos outros diagnósticos diferenciais. A maior variabilidade morfológica das lesões nos pacientes com menor comprometimento imunológico (CD4 maior) poderia ser devido à necessidade de um certo grau de imunidade na gênese das lesões cutâneas.

Osteocondrite dissecante da cabeça do úmero em cães: Estudo retrospectivo de 36 casos (1991-1996)

A osteocondrite dissecante da cabeça do úmero (OCD) é uma condição patológica da cartilagem articular, decorrente de distúrbio da ossificação endocondral. Foram analisados 36 casos de OCD em cães com idades compreendidas entre 5 e 24 meses, observando-se maior representação entre machos comparados com fêmeas (3,5:1). A maioria destes animais (80,6%) tinha recebido suplementação alimentar. Oito cães foram tratados conservativamente através de repouso e restrição alimentar, enquanto os demais foram submetidos a intervenção cirúrgica por meio de artrotomia e remoção do retalho de superfície articular da cabeça do úmero. Concluiu-se que a predisposição de algumas raças, associada ao desequilíbrio nutricional durante os primeiros meses de vida, são as causas determinantes da OCD, e que a cirurgia é a melhor terapia a ser empregada.

Dexamethasone-induced insulin resistance is associated with increased connexin 36 mRNA and protein expression in pancreatic rat islets

Augmented glucose-stimulated insulin secretion (GSIS) is an adaptive mechanism exhibited by pancreatic islets from insulin-resistant animal models. Gap junction proteins have been proposed to contribute to islet function. As such, we investigated the expression of connexin 36 (Cx36), connexin 43 (Cx43), and the glucose transporter Glut2 at mRNA and protein levels in pancreatic islets of dexamethasone (DEX)-induced insulin-resistant rats. Study rats received daily injections of DEX (1 mg/kg body mass, i.p.) for 5 days, whereas control rats (CTL) received saline solution. DEX rats exhibited peripheral insulin resistance, as indicated by the significant postabsorptive insulin levels and by the constant rate for glucose disappearance (K-ITT). GSIS was significantly higher in DEX islets (1.8-fold in 16.7 mmol/L glucose vs. CTL, p < 0.05). A significant increase of 2.25-fold in islet area was observed in DEX vs. CTL islets (p < 0.05). Cx36 mRNA expression was significantly augmented, Cx43 diminished, and Glut2 mRNA was unaltered in islets of DEX vs. CTL (p < 0.05). Cx36 protein expression was 1.6-fold higher than that of CTL islets (p < 0.05). Glut2 protein expression was unaltered and Cx43 was not detected at the protein level. We conclude that DEX-induced insulin resistance is accompanied by increased GSIS and this may be associated with increase of Cx36 protein expression.

Argon ion implantation inducing modifications in the properties of benzene plasma polymers

Benzene plasma polymer films were bombarded with Ar ions by plasma immersion ion implantation. The treatments were performed using argon pressure of 3 Pa and 70 W of applied power. The substrate holder was polarized with high voltage negative pulses (25 kV, 3 Hz). Exposure time to the immersion plasma, t, was varied from 0 to 9000 s. Optical gap and chemical composition of the samples were determined by ultraviolet-visible and Rutherford backscattering spectroscopies, respectively. Film wettability was investigated by the contact angle between a water drop and the film surface. Nanoindentation technique was employed in the hardness measurements. It was observed growth in carbon and oxygen concentrations while there was decrease in the concentration of H atoms with increasing t. Furthermore, film hardness and wettability increased and the optical gap decreased with t. Interpretation of these results is proposed in terms of the chain crosslinking and unsaturation.

Dental caries prevalence in children up to 36 months of age attending daycare centers in municipalities with different water fluoride content

This study determined the prevalence of cavitated caries lesions (CCL) and early childhood caries (ECC), and the contribution of some variables in children up to 36 months of age attending daycare centers in municipalities with different fluoride levels in the water supply: AFC (adequate fluoride content) and LFC (low fluoride content). After approval of the Ethics Committee, the parents were interviewed. The children were clinically examined using the same codes and criteria established by the WHO (World Health Organization) and the ADA (American Dental Association). Fisher's exact test (p<0.05) was applied for statistical analysis of data. The dmft indices calculated in the LFC and AFC municipalities were 0.57 and 0.68, respectively. Considering all children examined, 17.6% presented CCL and 33.8% ECC. The economic classification, mother's education level and duration of breastfeeding were considered statistically significant with regards to CCL prevalence. The age group, duration of the habit of drinking milk before bedtime and age at which oral hygiene started were considered statistically significant with regards to ECC prevalence.

Argon-based atmospheric pressure plasma enhances early bone response to rough titanium surfaces

This study investigated the effect of an Argon-based atmospheric pressure plasma (APP) surface treatment operated chairside at atmospheric pressure conditions applied immediately prior to dental implant placement in a canine model. Surfaces investigated comprised: rough titanium surface (Ti) and rough titanium surface + Argon-based APP (Ti-Plasma). Surface energy was characterized by the Owens-Wendt-Rabel-Kaelble method and chemistry by X-ray photoelectron spectroscopy (XPS). Six adult beagles dogs received two plateau-root form implants (n = 1 each surface) in each radii, providing implants that remained 1 and 3 weeks in vivo. Histometric parameters assessed were bone-to-implant contact (BIC) and bone area fraction occupancy (BAFO). Statistical analysis was performed by Kruskall-Wallis (95% level of significance) and Dunn's post-hoc test. The XPS analysis showed peaks of Ti, C, and O for the Ti and Ti- Plasma surfaces. Both surfaces presented carbon primarily as hydrocarbon (C?C, C?H) with lower levels of oxidized carbon forms. The Ti-Plasma presented large increase in the Ti (+11%) and O (+16%) elements for the Ti- Plasma group along with a decrease of 23% in surface-adsorbed C content. At 1 week no difference was found in histometric parameters between groups. At 3 weeks significantly higher BIC (>300%) and mean BAFO (>30%) were observed for Ti-Plasma treated surfaces. From a morphologic standpoint, improved interaction between connective tissue was observed at 1 week, likely leading to more uniform and higher bone formation at 3 weeks for the Ti-Plasma treated implants was observed.

Effect of orthognathic surgery for class III correction on quality of life as measured by SF-36

The purpose of this work was to evaluate the quality of life of patients with Angle's class III malocclusion submitted to orthognathic surgery. Twenty-nine patients of both sexes, ranging in age from 17 to 46 years, with Angle's class III malocclusion and indication for surgical treatment, were evaluated about 30 days before surgery and 6 months postoperatively. Surgery consisted of maxillary advancement or mandibular retrusion, or both. The generic SF-36 questionnaire was used to evaluate the following eight domains: functional capacity, physical aspects, pain, general health status, mental health, emotional aspects, social aspects and vitality. Descriptive and inferential statistical analyses were used to determine possible interactions between timing of evaluation, gender and type of surgery. With respect to physical and social aspects, a significant difference in outcomes was observed, with mean scores being higher after surgery regardless of gender or type of surgery. Regarding emotional aspects, an interaction effect was observed for timing and gender, with higher mean scores only being obtained for females after Surgery. Orthognathic Surgery had a positive impact on the quality of life of both male and female patients, improving physical and social aspects, and on that of female patients, improving emotional aspects.

Some possible evolutionary scenarios suggested by Cl-36 measurements in Guarani aquifer groundwaters

The Guarani aquifer underlies 1.2 M km(2) in the Parana sedimentary basin of South America and is an important source of water for industry, agriculture, and domestic supplies. To determine the sustainability of this aquifer we need to understand the dynamics of the groundwater system. This paper describes the first Cl-36 measurements on aquifer groundwaters and some measurements on South American rainwaters, thought to be indicative of the recharge water. The results are compared to previous work in the region, including other radioisotope analyses. A simple model is developed, incorporating radioactive decay, allowing scenarios to be developed for mixing different waters at different mixing rates. Thus, mixing scenarios consistent with other hydrogeological and hydrogeochemical data could be assessed. A model that mixes fresh recharging waters with formational waters, that contain elevated chloride levels, but low (in situ) Cl-36 levels, can explain most of the results presented here. The expectation that rainwater samples would provide a good end-member for modelling recharge proved problematic, however. As a consequence, it is suggested that either: the recharge waters are not sourced from the same locations as the rains; that the current rainfall and fallout conditions were significantly different in the past; or that the low levels of chloride in rainfall may have allowed some contamination of the samples by old (Cl-36-free) chloride during the recharge process.
