Estudio in vitro de la Microfiltración de un Sellante de Autograbado

PurposeThe purpose of this study was to examine differences in microleakage in extracted human teeth when placing sealants using conventional acid etching or a self-etching fissure sealant.MethodsA total of 40 intact molars and premolars were randomly assigned to one of two light-cured sealant groups: self-etching fissure sealant Enamel Loc™ (Premier)(Group 1, n=20) and Concise™ White Sealant using conventional acid etching (3M™ ESPE™) (Group 2, n=20). Before thermocycling (x100, 15-7 degrees C) all teeth surfaces were made impermeable with the exception of the occlusal surface. Samples were immersed in 50% silver nitrate for 24 hours, then immersed in Rx development solution (Kodak GBX) and after abrassioned longitudinally until central fissure pit. Pictures were obtained by light microscope and the presence of microleakage was evaluated by two calibrated evaluators (kappa= 0,95).ResultsSignificant statistical differences (p<0,0001) were observed between groups.ConclusionsSelf-etching fissure sealant Enamel Loc™ showed higher microleakage scores

Assistance circulatoire extracorporelle percutanée dans les défaillances hémodynamiques aiguës graves : Expérience monocentrique chez 100 patients consécutifs

Extracorporeal life support (ECLS) is a circulatory assistance device that is increasingly used in adults undergoing cardiopulmonary arrest (CPA) or hemodynamic collapse when conventional therapies fail.

and Signs Pain Scale (S-LANSS); and, 3. factors associated with NP symptoms as measured by the mPD-Q. Methods: Eligible participants were members of an established population-based OA cohort with chronic symptomatic knee OA. A standardized questionnaire was mailed to 426 cohort members to assess NP symptoms (mPD-Q, S-LANSS); osteoarthritis status (WOMAC, Von Korff Chronic Pain Grade); psychological factors including depression (Center for Epidemiological Studies Depression Scale), anxiety (Hospital Anxiety and Depression scale) pain catastrophizing (Pain Catastrophizing Scale), and sleepiness (Epworth Daytime Sleepiness scale); co-morbid medical conditions; possible confounding neurological conditions; and medication use. The cut-point score (≥19) identified in other chronic pain populations was used to identify NP symptoms (‘NP range’ scores) in this study. The proportion of knee OA participants with mPD-Q scores in the NP range was calculated using a 95% confidence interval (CI). Spearman’s correlation between continuous mPD-Q and S-LANSS scores was examined. Potential correlates of NP symptoms were first assessed using bivariate analysis, followed by logistic regression modeling. Results: Out of 426 cohort members who were sent a study questionnaire, 259 were deemed eligible to participate. The response rate among eligible cohort members was 66% (171/259). The proportion (95% CI) of participants with mPD-Q scores in the NP range was 0.28 (0.21-0.35). After removal of participants with neurological conditions, 0.19 (0.12-0.29) still had scores in the NP range. Continuous mPD-Q scores were highly correlated with continuous S-LANSS scores. NP range scores were strongly associated with OA severity, depressive and anxious symptoms, pain catastrophizing, and a higher frequency of neurological conditions, and chronic back or hip pain with radiation down either leg (‘pain radiation’). On multivariable analysis, pain intensity, ‘pain radiation’, and neurological conditions were independently related to NP range scores. Conclusions: A substantial proportion of older adults with chronic symptomatic knee OA had symptoms of NP on the mPD-Q suggesting neuropathic mechanisms may be contributing to their pain experience. This subgroup of people may benefit from further evaluation for NP and consideration of NP medications. Validation work is ongoing on the mPD-Q, which may serve as a clinically feasible tool to aid the identification of NP in people with OA.

variables to predict medial compartment loading during walking in patients with knee OA. As we hypothesized, the effect of body mass on the KAM depends on the extent of limb malalignment. Those with greatest malalignment exhibit the greatest association between mass and peak knee adduction moment. Individuals with both increased mass and increased malalignment may benefit most from earlier intervention strategies intended to decrease dynamic knee joint loads.
