Efficacy of sodium hypochlorite and coconut soap used as disinfecting agents in the reduction of denture stomatitis, Streptococcus mutans and Candida albicans.

This study evaluated the reduction of denture stomatitis and the antimicrobial activity of 0.05% sodium hypochlorite opposed to Candida albicans and Streptococcus mutans (SGM) when associated with brushing complete dentures with coconut soap. The mucosal characteristics were evaluated according to Newton's classification at baseline, after cleansing the dentures with coconut soap for 15 days in group 1 (nine patients). In the other group (19 patients) the analysis were made before and after cleansing the dentures with coconut soap and with disinfection in a soak solution of 0.05% sodium hypochlorite for 10 min during 15 days. Microbiological tests were used to isolate C. albicans and SGM. Mann-Whitney and Wilcoxon tests were used to compare the mucosal characteristics and Fisher test and McNemar test to compare C. albicans and SGM levels. Statistical analysis at the 95% confidence level (P < 0.05) showed that: (i) the association of coconut soap and 0.05% sodium hypochlorite significantly reduced clinical signs of denture stomatitis, (ii) C. albicans did not reduce in counts, (iii) SGM were reduced but not significantly and (iv) the association of coconut soap and 0.5% sodium hypochlorite was effective in controlling denture biofilm.

[Bluish cutaneo-digestive angiomatosis or Bean's blue rubber-bleb nevus. A rare syndrome]. / L'angiomatose bleutée cutanéo-digestive ou blue rubber bleb nevus de Bean. Un syndrome rare.

Upper digestive tract hemorrhage in cirrhotic patients. Contribution of multidimensional analysis to the study of variables related to the cause of the hemorrhage.

Sixteen clinical and biological variables were recorded in 116 episodes of upper digestive tract hemorrhage of known cause in cirrhotic patients. One-dimensional analysis reveals a significant correlation between six variables and the rupture of esophagogastric varices, whereas multiple linear regression and partial correlation analysis reduces the significant variables to two: a history of digestive hemorrhage and the nonalcoholic etiology of the cirrhosis. A value of the discriminant function exists for which the specificity and, consequently, the positive predictive value are equal to 100%, but with a sensitivity of 39%. These results mean that, in an explanatory approach, partial correlation analysis seems to constitute an indispensable complement to analysis of clinical and biological variables, since it reduces the chances of unwarranted explanatory interpretation. However, in a pragmatic approach, the recording of 16 variables does not permit a clear discrimination between ruptured varices and nonruptured varices; this suggests that either other factor(s) remain to be discovered or else that those related to ruptured varices and to acute ulcerations are the same.
