Innate sensing of microbial products promotes wound-induced skin cancer.

The association between tissue damage, chronic inflammation and cancer is well known. However, the underlying mechanisms are unclear. Here we characterize a mouse model in which constitutive epidermal extracellular-signal-regulated kinase-MAP-kinase signalling results in epidermal inflammation, and skin wounding induces tumours.

Implants failures related to endodontic treatment. An observational retrospective study.

Objective: The aim of the study was to analyze potential etiological risk factors that constitute a complex problem in the clinical management of peri-implantitis.

Materials And Methods: An observational retrospective study was conducted to describe the possible effect of lesions of origin pulpar and/or periapical success or failure of the implant. The sample consisted of review of 800 implants, of which 500 were conducted at the Faculty of Dentistry of the UANL and 300 private clinics of Maxillofacial surgeons experienced in the placement of those who reside in Monterrey, Mexico.

Predictors of peri-implant bone loss during long-term maintenance of patients treated with 10-mm implants and single crown restorations.

Purpose: The aim of this retrospective study was to evaluate the predictors of peri-implant bone loss in a sample of patients treated with 10-mm implants and single crowns who underwent periodontal/peri-implant maintenance (PM) in a Mexican private periodontal practice.

Materials And Methods: Outcomes of a group of systemically healthy, partially edentulous patients attended up to July 2012 were assessed. Patient data were considered for inclusion if they involved treatment of partially edentulous sites with 10-mm-long implants and single crown restorations, as well as at least 3 years of regular PM following implant placement.

Laparoscopic pediatric inguinal hernia repair: no ligation, just resection.

Background: There have been descriptions of several techniques for congenital inguinal hernia (CIH) repair in the pediatric population by doing high ligation of the sac, without a definitive advantage over the open procedure. High recurrence rates have been reported with using these minimally invasive techniques in which the patent processus vaginalis has been ligated and left in place completely or partially.

Methods: With approval of the ethics committee, a proper informed consent was obtained.

Delayed lung maturation of foetus of diabetic mother rats develop with a diminish, but without changes in the proportion of type I and II pneumocytes, and decreased expression of protein D-associated surfactant factor.

Newborn children of diabetic mothers have an increased morbidity and mortality because of respiratory distress syndrome. We study lung histogenesis during intrauterine development of offspring of diabetic Sprague-Dawley rats at 18, 19 and 21 days of gestation (DG). Pregnant rats were grouped into diabetic (streptozotocin-induced), citrate, and control groups; five female and five male offspring were selected randomly from each group at 18, 19 and 21 DG, and a biopsy of the lung was taken and processed in paraffin for histological examination.
