Tuberculose em trabalhadores de enfermagem: uma abordagem epidemiológica de base populacional
Lorenzi, Ricardo Luiz;Oliveira, Ivone Martini de;
Revista Brasileira de Saúde Ocupacional , 2008, DOI: 10.1590/S0303-76572008000100002
Abstract: introduction: the risk of tuberculosis in health-care workers has brought growing concerns to society and researchers from developed countries. in brazil there is still a gap between epidemiological knowledge and know-how in this field. this problem requires a more detailed investigation to give support and to provide better application to occupational safety and health regulations, such as the regulatory act called "nr-32". methods: using sao paulo tuberculosis program database "epi-tb" and calculating the standardized incidence ratio, the authors estimated nursing personnel risks. the reference for the study was the population in the city of sao paulo in the year 2004. employers' profiles are described according to health-care facility status, based upon the state of sao paulo nursing council - coren's database. results: approximately 90% of cases registered by the epi-tb notification instrument had their occupation validated by coren's database. the 20-29 age interval showed an increased risk among nurses when compared to the reference population. among 15 to19 year-old nurses'aides there was also an increase of risk. conclusions: nursing personnel may be considered as a nosocomial tuberculosis index category, and monitoring nosocomial tb seems to be feasible since changes are provided in the notification instrument of this disease. the study has tackled possible implications of articulated actions between different institutional actors on prevention and control of tuberculosis, and it discusses ways to overcome current anachronisms in health surveillance practices.

Abstract: background: alcoholic or biliary acute pancreatitis may need different therapeutic approaches. aim: assessing the validity of lipase/amylase ratio in differentiating biliary from alcoholic acute pancreatitis/acutized chronic pancreatitis. methods: nine male patients (mean age and standard deviation: 39.8 ± 7.0 years) with alcoholic acute pancreatitis/acutized chronic pancreatitis (group i) and 29 patients, 8 male and 21 female (mean age: 43.6 ± 19.9 years), with biliary acute pancreatitis (group ii) were evaluated. serum lipase and amylase levels were measured in patients with symptoms for no more than 48 hours. the lipase/amylase ratio was calculated based on serum lipase and amylase levels and expressed as multiples of their respective superior reference values. results: mean levels of serum lipase (4,814 ± 3,670 u/l) and amylase (1,282 ± 777 u/l) in patients of group i were comparable to group ii (2,697 ± 2,391 and 1,878 ± 1,319 u/l, respectively), but the mean lipase/amylase ratio was significantly higher in group i (4.4 ± 3.6) than in group ii (2.2 ± 2.2). lipase/amylase ratio >3 occurred at significantly higher proportions in patients of group i (66.7%) than of group ii (24.1%), differentiating the two groups with sensitivity of 67% and specificity of 76%. conclusions: 1) amylase and lipase serum levels did not differ in the two groups evaluated; 2) the lipase/amylase ratio >3 was more often seen in alcoholic acute pancreatitis/acutized chronic pancreatitis than biliary acute pancreatitis, and it may be useful in differentiating these two causes of pancreatitis.

Santos, Eduardo Luiz Nigri dos;Oliveira, Ricardo Araujo;
Revista Brasileira de Cirurgia Plástica , 2012, DOI: 10.1590/S1983-51752012000300026
Abstract: the suture of extensive wounds remains a major challenge for plastic surgeons. the objective of this article is to promote use of elastic sutures as an effective procedure for the closure of extensive wounds. fourteen patients presenting with extensive wounds caused by trauma in the lower limbs were included in the study. the entire wound was sutured in each patient with a two-step procedure. in the first step, the opposite edges of the wound were approximated using rubber circular elastic bands. in the second step, carried out a few days later, the elastic bands were removed, followed by a simple suture with monofilament nylon thread. placement of elastic sutures proved to be a safe, functionally effective, easy-to-perform, and low-cost procedure for the closure of extensive wounds without using donor areas as skin grafts.

Abstract: This work has brought about the understanding of background that explains the intention of the bank clients accepting mobile banking - the self-service banking that is done by using a mobile channel - as a new way of interaction with the banks. In achieving this objective, it has developed a conceptual mark in respect of the advances in the information technology's field in the banking sector. Furthermore, it has been showed some patterns that explain the behaviour of the consumers in the using of innovation. Beyond the showed patterns, it has been chosen to be tested the Decomposed Theory of Planned Behaviour (TAYLOR and TODD,1995). The procedure of this conclusive and descriptive study happened in two stages. In the exploratory stage there have been interviews and group sessions with a particular focal point. In the descriptive stage, the quantitative analysis, it explored the validation of a sample of 515 banking clients. Multivariate techniques, like Modelling of Structural Equation have been used in the statistic analysis of the data. The results validate the pattern, however with some alterations. The factors Subjective Rules and Perception Control did not have a significant impact in the behaviourist intention, wich contradicts the original pattern test. Another difference of this study was the inclusion of a new variable in the original pattern - security, inserted in the analysis from the exploratory stage of the data collection. This factor showed the influence of the interaction and adoption of new technologies. The relationships between the factors found support in the analysis of the data. It has been proved that the variation in the attitude and security, explain 74% of the variation of the intention in using mobile banking by the participants. Furthermore, through this work it has been found that the interation is an antecedent of the real behaviour, corroborating with what is said in the bibliography. Perception control and intention achieved R2 of 0,28 in the explanation of the real behaviour.

Abstract: O fechamento de grandes feridas continua sendo um importante desafio para o cirurgi o plástico. O objetivo deste artigo é a divulga o da sutura elástica como uma técnica eficaz para o fechamento de grandes feridas. Foram incluídos no estudo 14 pacientes portadores de grandes les es decorrentes de traumas diversos em membros inferiores. O fechamento completo das feridas foi obtido por procedimento dividido em duas etapas, sendo a primeira representada por aproxima o das bordas opostas da ferida por meio de tiras circulares elásticas de borracha e a segunda, realizada alguns dias após, com a retirada das tiras elásticas, seguida de sutura simples com fio mononáilon. A sutura elástica demonstrou ser uma técnica segura, funcionalmente eficaz, de fácil execu o e de baixo custo para fechamento de grandes feridas, evitando áreas doadoras, como nos enxertos de pele.

Abstract: Background: Diabetes mellitus is a worldwide epidemic. In 2002 there were 173 million diabetic adults worldwide, and these numbers are expected to reach up to 300 million people by 2030. Meanwhile, vitamin D deficiency has its worldwide prevalence directly influenced by factors as solar radiation, skin color, latitude and seasons, cultural habits of populations such as clothing and food, and these factors are important to explain the different prevalences of vitamin D deficiency in the world. Methods: A prospective cross-sectional cohort study was conducted with patients in the outpatient clinic of the Health Unit of the city of Mangueirinha, Paraná, Southern Brazil. Fifty-four type 2 diabetic patients were evaluated (38 women and 16 men), aged 55.8 ± 12.6 years. The following variables were evaluated: age, ethnicity, presence of type 2 diabetes (DM2), hypertension, dyslipidemia, weight, BMI, WC, blood pressure, blood glucose, glycated hemoglobin, ionized calcium, PTH, 25-OH Vit, total cholesterol, HDL, LDL, urea, creatinine, uric acid and red cell/hematocrit. Results: mean BMI was 30.2 ± 4.4 kg/m2, indicating class 1 obesity in this population. Fasting glucose levels were approximately 169.8 ± 74.5 mg/dL. The 25-OH vitamin D values for this population were 23.4 ± 8.3 ng/mL, and 13% of them showed 25-OH vitamin D levels above 30 mg/dL. Fifty percent of those patients had vitamin D levels lower than 30 mg/dL, and 37% had less than 20 mg/dL. Conclusions: this study suggests that vitamin D is associated with low levels of vitamin D in type 2 diabetic patients. Supplementation of vitamin D should be considered in diabetic patients, when levels under 30 mg/mL are found.

Abstract: leaf vapor diffusive conductance (gl) and transpiration (t) measurements in an irrigated orchard of the acid lime "tahiti" were carried out in a subtropical climatic condition in the state of s?o paulo, brazil. measurements were made using steady-state null-balance porometers and were taken throughout the day, on several occasions from february to november, 1998. during september and october, measurements were performed on exposed and shaded young and fully expanded leaves, as well as on old leaves inside the tree canopy. the old leaves showed lower values of gl and t when compared to the other groups. in the other months, measurements were taken only with exposed and shaded fully expanded leaves. the highest values of gl and t were obtained from february to april. for exposed leaves gl was higher from early morning to midday, decreasing thereafter with some oscillation in the afternoon. shaded leaves produced a pattern of increasing gl and t from 8:00-9:00 a.m. to midday, followed by a decrease when values matched those of the exposed leaves in the afternoon. in april, the first measurement in midmorning showed low gl and t values, increasing sharply in the exposed leaves until midday and then decreasing until the end of the afternoon. between may and november, gl and t decreased sharply compared to the previous months. boundary line and regression analysis were used to find the mathematical relationships between mean values of gl for the tree and photosynthetic photons flux density, temperature, and vapor pressure deficit of the air measured in the orchard. based on this analysis, the reasons for the gl and t diurnal and annual variation patterns are discussed, with emphasis on the effects of atmospheric variables upon stomatal regulation.

Abstract: Leaf vapor diffusive conductance (gl) and transpiration (T) measurements in an irrigated orchard of the acid lime "Tahiti" were carried out in a subtropical climatic condition in the State of S o Paulo, Brazil. Measurements were made using steady-state null-balance porometers and were taken throughout the day, on several occasions from February to November, 1998. During September and October, measurements were performed on exposed and shaded young and fully expanded leaves, as well as on old leaves inside the tree canopy. The old leaves showed lower values of gl and T when compared to the other groups. In the other months, measurements were taken only with exposed and shaded fully expanded leaves. The highest values of gl and T were obtained from February to April. For exposed leaves gl was higher from early morning to midday, decreasing thereafter with some oscillation in the afternoon. Shaded leaves produced a pattern of increasing gl and T from 8:00-9:00 a.m. to midday, followed by a decrease when values matched those of the exposed leaves in the afternoon. In April, the first measurement in midmorning showed low gl and T values, increasing sharply in the exposed leaves until midday and then decreasing until the end of the afternoon. Between May and November, gl and T decreased sharply compared to the previous months. Boundary line and regression analysis were used to find the mathematical relationships between mean values of gl for the tree and photosynthetic photons flux density, temperature, and vapor pressure deficit of the air measured in the orchard. Based on this analysis, the reasons for the gl and T diurnal and annual variation patterns are discussed, with emphasis on the effects of atmospheric variables upon stomatal regulation.
