Fetal Endoscopic Third Ventriculostomy Is Technically Feasible in Prenatally Induced Hydrocephalus Ovine Model.

Background: Congenital obstructive hydrocephalus generates progressive irreversible fetal brain damage by ventricular enlargement and incremental brain tissue compression that leads to maldevelopment and poor clinical outcomes. Intrauterine treatments such as ventriculo-amniotic shunting have been unsuccessfully tried in the eighties.

Objective: To assess if prenatal endoscopic third ventriculostomy (ETV) is feasible in a large animal model and optimize this technique for ventricular decompression and potential arrest of fetal brain damage in fetal lambs.

In Vitro and In Vivo Response of Zinc-Containing Mesoporous Bioactive Glasses in a Sheep Animal Model.

Zinc-enriched mesoporous bioactive glasses (MBGs) are bioceramics with potential antibacterial and osteogenic properties. However, few assays have been performed to study these properties in animal models. In this study, MBGs enriched with up to 5% ZnO were synthesized, physicochemically characterized, and evaluated for their osteogenic activity both in vitro and in vivo.

Effects of peri-implant infection on serum biochemical analysis.

Background: Peri-implant disease (PID) has not been directly linked to pathological organ changes. The present study assessed the dynamics of serum biochemical parameters in a model of experimental peri-implantitis in dogs, followed by open flap debridement.

Methods: Seven male beagle dogs comprised the study group.

Peri-implant disease affects systemic complete blood count values-an experimental in vivo study.

Objectives: To assess complete blood count (CBC) dynamics following ligature removal and open flap debridement in experimental peri-implantitis in dogs.

Materials And Methods: Seven male beagle dogs were included in the study. Four rough-surface implants were placed pair-wise in both sides of the mandible 14 weeks after tooth extraction.

[Evaluation of competencies in urology. Esscolap® basic, as aproximation to urologists skills improvement.].

Unlabelled: Urology needs models of competencies assessment, although there is a wide range of tools not yet integrated into the official training programs.

Context: At present, there is no universal framework for measuring surgeons' level of competence. Urology training programs should provide and consider knowledge, pyschomotor/cognitive skills, and simulator, cadaver or animal models-based training.

Development and initial assessment of a training program for laparoscopic radical prostatectomy. First module: the urethrovesical anastomosis.

Purpose: We present our experience in the design and development of a training program in laparoscopic radical prostatectomy (LRP), and the validation of the first steps of the program by objective measurement of the attendants' skills improvement and subjective evaluation of its contents.

Materials And Methods: Our training model on LRP has a total duration of 42 hours, divided in two modules of 21 hours each, performed 1 month apart. Data included in the present study were obtained from the first module of our course.
