[Survival and associated factors with long-term survival of penile prosthesis]. / Survie et facteurs associes à la durée de vie des prothèses péniennes a long terme.

INTRODUCTION: Implantation of penile prosthesis is constantly growing but little long-term data is available concerning the associated factors of prosthesis survival. Our aim was to describe the long-term survival of penile prostheses and to identify factors influencing long-term prosthesis survival. METHODS: This is a retrospective, monocentric cohort of patients who underwent their first implantation of a penile prosthesis, between May 2000 and March 2017, at the Reims University Hospital. Prosthesis survival was calculated by the Kaplan-Meier method. A univariate and multivariate analysis to estimate the risk of surgical removal/revision of the prosthesis was performed using a Cox model. RESULTS: 150 patients were included, and 61 patients underwent surgical removal of the prosthesis (40.7%). Mean follow-up was 76.12 months (0-176 months). Prosthesis survival was 69.7% at 5 years (95% CI, 62.2-77.3) and 58.5% at 10 years (95% CI, 50.0-66.9). In multivariate analysis, the factors influencing prosthesis survival were: type of prosthesis (other vs. Coloplast TITAN®, HR 1.89, CI 95%, 1.03-3.45) and prosthesis final length (20-29cm vs. 12-17cm, HR 0.27, 95% CI, 0.09-0.77). CONCLUSION: At 10 years, the penile prosthesis survival is close to 60%. Type of implant and final length of the prosthesis may have a significant influence in long-term prosthesis survival. Patients undergoing penile prosthesis implantation must be informed about the risk of surgical removal/revision of the prosthesis. LEVEL OF EVIDENCE: 3.

Effect of dietary fiber and fat on performance and digestive traits of broilers from one to twenty-one days of age.

The influence of fiber source and dietary fat level on digestive traits and productive performance was studied in broilers from 1 to 21 d of age. There were 6 treatments arranged factorially with 3 sources of fiber (none; 3% oat hulls, OH; and 3% sugar beet pulp, SBP) and 2 fat sources (5% soybean oil, SO; and 5% yellow grease, YG). Each treatment was replicated 6 times and the experimental unit was a cage with 18 broilers. Fiber inclusion improved BW gain (P < or = 0.05) and feed:gain ratio (P < or = 0.001) and increased total tract apparent retention (TTAR) of all nutrients measured (P < or = 0.001). The increases observed in TTAR of nitrogen and ether extract and on AME(n) of the diet were more pronounced with OH than with SBP. The increases in nutrient digestibility with OH inclusion were higher at excreta than at ileal level and in fact, SBP inclusion reduced the apparent ileal digestibility of most nutrients. The relative weight (%) of the gizzard was increased (P < or = 0.001) and the pH of its contents was reduced (P < or = 0.001) when additional fiber was included in the diet. The TTAR of nutrients was higher for the SO than for the YG diets (P < or = 0.001). Also, the increases in ether extract digestibility (P < or = 0.05) and AME(n) (P < or = 0.05) of the diet with fiber inclusion were more pronounced with the YG than with the SO. Therefore, the inclusion of moderate amounts of fiber in the diet might improve performance and nutrient digestibility in young chicks, especially when saturated fats are used.

[Fluoride versus the profession]. / Flúor versus profesión.

Topical application of fluoride is the most frequently used procedure by those persons interviewed about the different methods employed in the prevention of dental decay in children. Of all the ways of administering fluoride, professionals consider as the most effective the fluoridization of drinking water and the least effective that of fluoridization of salt. Among the most common advice given by the professional to his patients is to prescribe a fluorinated tooth paste, this behavior being commonest amongst the youngest dental surgeons. Over half of the professionals do not prescribe fluoride supplement with vitamins. If they do this, the most important issue to consider is the child's age. The most appropriately applied criteria regarding the start of a diet containing fluoride supplement--according to the interviewees--correspond to pregnancy.
