Association entre la dégénérescence maculaire liée à l’âge et les parodontites

Purpose: To evaluate the association between age-related macular degeneration (AMD) and periodontal disease, two frequent conditions in the elderly, with some risk factors in common. Methods: Single center, pilot, case-control study performed in a center specialized in the diagnosis and management of AMD. Periodontal status was evaluated in 43 AMD patients and 19 controls. Fundus examination and a complete periodontal examination were performed in all subjects. Results: AMD patients have a greater percentage of 3–4 mm clinical attachment loss compared to controls (47% vs. 38%, [P = 0.039]). However, no significant difference was found between the groups with regard to the prevalence of severe periodontitis. Conclusions: These results suggest an association between AMD and attachment loss characteristic of periodontal disease and support the need for larger prospective studies to elucidate the relationships between these 2 highly prevalent and potentially severe diseases

Comparative Study With Propensity Score Matching Analysis of Two Different Methods of Transection During Hemi-Right Hepatectomy: Ultracision Harmonic Scalpel Versus Cavitron Ultrasonic Surgical Aspirator

BACKGROUND: Several devices are available for liver parenchyma transection (LPT). The aim of this study was to compare the Ultracision Harmonic scalpel (UHS) with the Cavitron Ultrasonic Surgical Aspirator (CUSA) among patients who underwent hemi-right hepatectomies (RH) to homogenize transection areas. METHODS: From September 2012 to June 2015, 24 patients who underwent the UHS surgery approach were matched with 24 patients who underwent the CUSA transection procedure for RH using propensity score matching. RESULTS: Total operative time (TOT) was shorter in the UHS group, 240 minutes (range 172.5-298.8) versus 330 minutes (range 270-400) in the CUSA group ( P = .0002). The occurrence of hepatopathy (odds ratio = 17; 95% confidence interval = 1.02-230) and the use of the CUSA device (odds ratio = 8; 95% confidence interval = 0.98-77) were associated with a TOT exceeding 300 minutes in multivariate analysis ( P = .05). CONCLUSIONS: The UHS is a safe and effective method of LPT as compared to the use of the CUSA system. TOT is statistically decreased
