Brachytherapy using gold-198 foils in treatment of mouth tumors: case report

The authors presents a clinical case treated with brachytherapy performed with special mold of gold-198 disc, with the purpose of evaluating the distribution of radiation dose, the viability of manufacturing the radioactivity prosthesis and its operational cost. In despite of being only one case, we can conclude that the prosthesis with gold-198 foils can be manufactured in acrylic with thickness thinner than those ones with cylinder of cesium-137, resulting lower operational costs, besides permitting better distribution of radiation dose on the lesion.

Efficacy of mouth rinses and toothpaste on tooth whitening.

People increasingly desire tooth whitening. Considering the wide range of whitening products on the market, this study evaluated the efficacy of whitening toothpastes and mouth rinses compared with the 10% carbamide peroxide (CP) whitening gel. We obtained 120 cylindrical specimens from bovine teeth, which were darkened for 24 hours in a coffee solution. The color measurement was performed by a spectrophotometer using the CIE L*a*b* system, and specimens were divided into six groups according to the use of the following agents: group 1, conventional fluoridated toothpaste; group 2, Close Up White Now; group 3, Listerine Whitening; group 4, Colgate Plax Whitening; group 5, experimental mouth rinse with Plasdone; and group 6, 10% CP Whiteness Perfect. After the simulation of 12 weeks of treatment for groups 1 to 5 and 14 days of treatment for group 6, the specimens were subjected to a new color reading. Data were subjected to one-way analysis of variance (α=0.05), which showed significant differences among groups after 12 weeks for ΔE (p=0.001). Results of the Tukey test revealed that groups 3, 4, and 6 presented significantly higher color alteration than groups 1, 2, and 5. The whitening toothpaste Close Up White Now and the experimental mouth rinse with Plasdone showed similar color alteration as conventional toothpaste after a 12-week treatment simulation. These groups presented significantly lower color alteration compared with whitening mouth rinses Listerine and Colgate Plax Whitening, which showed similar results to those observed after 14 days of bleaching with 10% CP treatment.

In vitro evaluation of the effect of mouth rinse with trimetaphosphate on enamel demineralization

Objective: The aim of this study was to investigate the effectiveness of sodium trimetaphosphate (TMP) addition to mouth rinses to inhibit enamel demineralization. Design: Bovine enamel blocks (n = 88) were selected by surface hardness and divided into eight treatment groups (n = 11 per group): placebo, 100 or 225 μg F/ml; the rinses with 100 μg F/ml had differing TMP concentrations (range 0-0.6%). The blocks were subjected to pH cycling for 5 days and treated twice a day with mouth rinses. After that, surface and cross-sectional hardness as well as fluoride in enamel were measured. Results: The groups containing both 100 μg F/ml and 0.4% TMP inhibited demineralization most effectively (p < 0.001). This formulation yielded lower values of lesion areas than the formulations containing 100 or 225 μg F/ml but no TMP. The addition of 0.4% TMP increased the fluoride in enamel. Conclusion: It is possible to improve the effectiveness of a mouth rinse with 100 μg F/ml by addition of TMP, this being superior in inhibiting enamel demineralization compared with mouth rinses containing 225 μg F/ml. © 2013 S.

The education of the body for an "integral soldier", "physically strong, intelligent and soul superior"

This study examines the paramilitary training carried out by the Integralist Militia (Militia Integralista), unit of the Brazilian Integralist Action (Acao Integralista Brasileira, AIB) of the extreme right wing political party in Brazil in the 1930s. The training was aimed to create the "integral soldier", a "physically strong, intelligent and soul superior" one. The study analyzes issues of the newspaper "Monitor Integralista", a prescriptive and dogmatic journal of the movement, found in the Public and History Archives of the city of Rio Claro, State of Sao Paulo, and in the "A Offensiva" newspaper, microfilmed an archived at the National Library of Rio de Janeiro. It concludes that Plinio Salgado's goal, the National Head of the AIB, was to train, by using verbal persuasion, speeches, word of mouth and by vote, by force and physical combat, the integralists to defend the causes of the movement.

Antecedents of the Intent to Recommend: a problem with fast food restaurants

The fast and strong social and economic transformations in the economies of many countries has raised the competition for consumers. One of the elements required to adapt to such scenario is knowing customers and their perceptions about products or services, mainly regarding word of mouth recommendations. This study adapts, to the fast food business, a model originally designed to analyze the antecedents of the intent to recommend by clients of formal restaurants. Three constructs were considered: service quality, satisfaction, and social well-being, the latter comprised of positive and negative affections. Six hypotheses were considered, three of which relating to social well-being (that it influences satisfaction, service quality, and the intent to recommend), two relating to service quality (that in influences the intent to recommend and satisfaction), and one relating to the influence of satisfaction on the intent to recommend. None was rejected, indicating adherence and adjustment of the simplication and adaptation of the consolidated model. Through a successful empirical application, the main contribution made by this research is the simplification of a model through its application in a similar context, but with a different scope.

Aortic neck dilatation after endovascular abdominal aortic aneurysm repair: a word of caution

Continuing aortic neck dilatation, most probably an expression of ongoing aneurysmal wall degeneration of the infrarenal aortic segment, has been shown to seriously impair clinical results after endovascular abdominal aortic aneurysm repair. However, conflicting data on the extent and clinical relevance on this observation have recently been published. This article reviews the recent literature, summarizing our current understanding of the role of aortic neck dilatation after open surgical and endovascular abdominal aortic aneurysm repair. In addition, differences in methodology of studies on aortic neck dilatation are highlighted.
