Abstract: a means of measurement, the application of which is similar to that of the first stages of the thurstone scale, using the method of apparently equal intervals and based on stephenson's q-technique, was elaborated, by using this tool it was planned to carry out a study on the function perception of the public health educator on the health team. the study comprises two phases: the first dealing with the construction of the instrument it self and the second with the making of a research survey, using the same. it is described every step of the first phase which consists of: gathering of information on the function assigned to the public health educator; list of the functions; turning them into statements transcribed into cards; selection of a sample of 70 cards, by a highly specialized board of judges; tabulation of the data obtained and definition of the definitive instrument. to fulfil the requisites of validity the scaling distribution should present a certain balance among the pertinent, intermediate, and non-pertinent statements. for statistical convenience and to guarantee such a balance each judge is told to place varying numbers of cards on several piles, turning its totality into a continuum approaching a normal or nearly normal distribution. such a balance has been attained and a distribution of the frequency statements sampled by the judges has shown an excellent internal agreement which qualifies this study as satisfactory. the statements have been proved to be definitive components of the measuring tool - percep??o da fun??o do educador na saúde pública (perception of the function of the educator in public health).

Journal of Applied Oral Science , 2010, DOI: 10.1590/S1678-77572010000500006
Abstract: this in vitro study evaluated the cytotoxicity of an experimental restorative composite resin subjected to different light-curing regimens. methods: forty round-shaped specimens were prepared and randomly assigned to four experimental groups (n=10), as follows: in group 1, no light-curing; in groups 2, 3 and 4, the composite resin specimens were light-cured for 20, 40 or 60 s, respectively. in group 5, filter paper discs soaked in 5 μl pbs were used as negative controls. the resin specimens and paper discs were placed in wells of 24-well plates in which the odontoblast-like cells mdpc-23 (30,000 cells/cm2) were plated and incubated in a humidified incubator with 5% co2 and 95% air at 37oc for 72 h. the cytotoxicity was evaluated by the cell metabolism (mtt assay) and cell morphology (sem). the data were analyzed statistically by kruskal-wallis and mann-whitney tests (p<0.05). results: in g1, cell metabolism decreased by 86.2%, indicating a severe cytotoxicity of the non-light-cured composite resin. on the other hand, cell metabolism decreased by only 13.3% and 13.5% in g2 and g3, respectively. no cytotoxic effects were observed in g4 and g5. in g1, only a few round-shaped cells with short processes on their cytoplasmic membrane were observed. in the other experimental groups as well as in control group, a number of spindle-shaped cells with long cytoplasmic processes were found. conclusion: regardless of the photoactivation time used in the present investigation, the experimental composite resin presented mild to no toxic effects to the odontoblast-like mdpc-23 cells. however, intense cytotoxic effects occurred when no light-curing was performed.

Journal of Applied Oral Science , 2010, DOI: 10.1590/S1678-77572010000100010
Abstract: chlorhexidine gluconate (chx) is recommended for a number of clinical procedures and it has been pointed out as a potential cavity cleanser to be applied before adhesive restoration of dental cavities. objective: as chx may diffuse through the dentinal tubules to reach a monolayer of odontoblasts that underlies the dentin substrate, this study evaluated the cytotoxic effects of different concentrations of chx on cultured odontoblast-like cells (mdpc-23). material and methods: cells were cultured and exposed to chx solutions at concentrations of 0.06%, 0.12%, 0.2%, 1% and 2%. pure culture medium (α-mem) and 3% hydrogen peroxide were used as negative and positive control, respectively. after exposing the cultured cells to the controls and chx solutions for 60 s, 2 h or 60 s with a 24-h recovery period, cell metabolism (mtt assay) and total protein concentration were evaluated. cell morphology was assessed under scanning electron microscopy. chx had a dose-dependent toxic effect on the mdpc-23 cells. results: statistically significant difference was observed when the cells were exposed to chx in all periods (p<0.05). significant difference was also determined for all chx concentrations (p<0.05). the 60-s exposure time was the least cytotoxic (p<0.05), while exposure to chx for 60 s with a 24-h recovery period was the most toxic to the cells (p<0.05). conclusion: regardless of the exposure time, all chx concentrations had a high direct cytotoxic effect to cultured mdpc-23 cells.

Abstract: yoga is an ancient philosophic system that originated in india and whose main objective is the development of the union of mind and body through exercise, respiration and meditation. the objective of this study was to assess the effects of regular practice of hatha yoga on the respiratory function of healthy women. a controlled cross-sectional study was conducted on 25 female volunteers divided into two groups: yoga (n=13) and control (n=12). the volunteers of the yoga group had practiced hatha yoga for at least 6 months. the respiratory rate was counted over one minute. maximal inspiratory and expiratory pressures were assessed with a manovacuometer. axillary and xiphoid mobilities were assessed by cyrtometry. chest expansion at the axillary and xiphoid levels was measured by cyrtometry. forced vital capacity and peak expiratory flow were assessed by spirometry. significant differences between groups were only observed for respiratory rate and xiphoid mobility. in conclusion, regular practice of hatha yoga had a positive impact on respiratory rate and xiphoid mobility in the population studied.

Abstract: Anorexia nervosa exhibits one of the highest death rates among psychiatric patients and a relevant fraction of it is derived from undernutrition. Nutritional and medical treatment of extreme undernutrition present two very complex and conflicting tasks: (1) to avoid “refeeding syndrome” caused by a too fast correction of malnutrition; and (2) to avoid “underfeeding” caused by a too cautious refeeding. To obtain optimal treatment results, the caloric intake should be planned starting with indirect calorimetry measurements and electrolyte abnormalities accurately controlled and treated. This article reports the case of an anorexia nervosa young female affected by extreme undernutrition (BMI 9.6 kg/m2) who doubled her admission body weight (from 22.5 kg to 44 kg) in a reasonable time with the use of enteral tube feeding for gradual correction of undernutrition. Refeeding syndrome was avoided through a specialized and flexible program according to clinical, laboratory, and physiological findings.
