Overall-mouth disinfection by photodynamic therapy using curcumin.

Abstract: Background data: Photodynamic therapy is a technique that involves the activation of photosensitizers by light in the presence of tissue oxygen, resulting in the production of reactive radicals capable of inducing cell death. Objective: The present study assessed the overall susceptibility of pathogens of salivary flora to photodynamic therapy after sensitization with curcumin and exposure to blue light at 450 nm. Methods: A randomized trial was executed with 13 adult volunteers. Three different groups were analyzed: L-D- (no light, no drug; control group), L-D+ (treated only with the drug; curcumin group) and L+D+ (treated with drug and light; photodynamic therapy group). Non-stimulated saliva samples were collected for bacterial counts at baseline and after the experimental phase, and adverse events experienced were recorded. Serial dilutions were performed, and the resulting samples were cultured on blood agar plates in microaerophilic conditions. The number of colony-forming units was then de...

Randomised controlled trial of tetanus treatment with antitetanus immunoglobulin by the intrathecal or intramuscular route

Abstract: Objective To evaluate the effect of intrathecal therapy with human antitetanus immunoglobulin on clinical progression of and mortality from tetanus. Design Randomised controlled trial. Setting Intensive care unit of a university hospital, Pernambuco, Brazil. Participants 120 patients with tetanus allocated to antitetanus immunoglobulin by either the intrathecal and intramuscular route (n = 58) or the intramuscular route (n = 62; control group). Main outcome measures Clinical progression of disease, duration of hospital stay, duration of occurrence of spasms, complications, respiratory infection, respiratory failure or mechanical ventilation, duration of respiratory assistance, and mortality. Results Patients in the treatment group showed a better clinical progression than those in the control group (χ2 for trend 7.752, P = 0.005; difference in proportion of patients with improvement 20%, 95% confidence interval 4% to 35%). The duration of occurrence of spasms, hospital stay, and respiratory assistance were all shorter in patients the treatment group: respectively, 14.96, 0.0001 (difference in proportion of patients with spasms lasting ≤ 10 days 36%, 18% to 55%); 4.56, 0.03; and 6.56, 0.01 (proportion of patients who needed assistance for ≤ 10 days 69.2% in the treatment group and 30.8% in the control group (difference 38%, 12% to 65%)). Conclusion Patients treated with antitetanus immunoglobulin by the intrathecal route show better clinical progression than those treated by the intramuscular route.

Comparative study of health behavior among college students at the start and end of their courses

Abstract: OBJETIVO: Analisar as diferencas nas condutas de saude de estudantes da area de saude de universidades publicas no inicio e no final do curso. METODOS: Estudo realizado com amostra estratificada por curso e por universidade, de 735 estudantes de ciencias da saude de universidades publicas do estado de Pernambuco, em 2006. Os dados foram coletados com a aplicacao do questionario National College Health Risk Behavior Survey, validado previamente para utilizacao com estudantes universitarios. Para analise de associacao foi utilizado o teste qui-quadrado ou exato de Fisher. Os resultados foram considerados significantes para p<0,05. RESULTADOS: A maioria dos estudantes era do genero feminino (69,5%). Um menor percentual de estudantes ao final da graduacao informou morar com os pais ou responsaveis. As condutas de violencia, relacionadas ao peso e a atividade fisica nao apresentaram diferencas significativas, assim como a maioria das condutas de seguranca no trânsito e de alimentacao. O consumo de alcool (68,8% vs 83,3%), tabaco (40,7% vs 52,5%) e inalantes (10,2% vs 21,9%) e a pratica de relacao sexual (62,5% vs 85,0%) foram mais frequentes entre estudantes do final do curso, com diferencas estatisticamente significativas. CONCLUSOES: Em geral, as condutas de saude nao diferiram significativamente entre os estudantes do inicio e os do final do curso de graduacao na area de saude.

Prevalence of dental trauma in deciduous teeth of Brazilian children

Abstract: The aim of this study was to assess the prevalence of dental trauma as compared to the prevalence of dental caries in children aged 3-59 months. A cross-sectional study was carried out during the National Immunization Day for Polio in Recife, northeast Brazil. The sample comprised 3489 children under the age of 5. The clinical examination was performed by 123 previously trained dental students. The inter-examiner agreement for crown fracture was 90.32% and for tooth discoloration it was 83.87%. The prevalence of dental caries was assessed using the dmf-t index. The statistical methods included descriptive analysis and the chi-square test with a margin of error of 5%. A total of 56 142 teeth were examined and the prevalence of dental trauma was 14.9%. Dental fracture was the most prevalent injury observed in 516 teeth (0.9%), followed by discoloration in 191 (0.9%), intrusion in 12 (0.02%) and extrusion in five (0.008%). The most affected teeth were the upper central incisors. The prevalence of dental trauma increased significantly with age and family income (P Language: en
