Transvaginal treatment of anterior or central urogenital prolapse using six tension-free straps and light mesh.

Objective: To evaluate the feasibility, efficacy, complications, and outcomes of treatment of anterior or central compartment urogenital prolapse by placement of an anteroposterior 22-g/m(2) mesh with six straps through one anterior vaginal incision.

Methods: In a prospective study, patients treated for urogenital prolapse at a center in France between February 2008 and June 2011 were enrolled. Previous treatments, related interventions, intraoperative and postoperative complications, and anatomic outcomes were recorded during 3years of follow-up.

Reference ranges and distribution of placental volume by 3-dimensional virtual organ computer-aided analysis between 11 weeks and 13 weeks 6 days.

Objectives: The purpose of this study was to determine the feasibility, reproducibility, and distribution of placental volume measurements according to the crown-rump length between 11 weeks and 13 weeks 6 days.

Methods: Images were acquired in 128 pregnancies followed in Burgundy during first-trimester screening sonography using an abdominal 3-dimensional transducer. The placental volume was then calculated by the virtual organ computer-aided analysis method with a rotation angle of 30° by a single operator.

Loading and release of small hydrophobic molecules in multilayer films based on amphiphilic polysaccharides.

We report on the loading and release behaviors of polyelectrolyte multilayers based on hydrophobically modified carboxymethylpullulan (CMP) derivatives and poly(ethyleneimine) (PEI) toward hydrophobic dye. The dye-loaded films are obtained according to two different protocols: (i) the postdiffusion approach, which involves the diffusion of the dye within preassembled self-assemblies, and (ii) the precomplexation method, which requires the formation of a water-soluble amphiphilic CMP derivative-dye complex before the multilayer buildup. In both cases, we provide clear evidence for the entrapment of the dye in hydrophobic nanoreservoirs resulting from the aggregation of decyl pendent groups grafted on CMP chains.
