[Genotyping and antibacterial resistance of Campylobacter spp strains isolated in children and in free range poultry].

Poultry is a main reservoir and source of human infection in campylobacteriosis. Three hundred and forty one stool samples (291 human, 50 avian) were analyzed. In the human group, 220 samples were collected from children with acute diarrheal disease (183 inpatients, 37 outpatients) and 71 from healthy children.

[Vitamin D receptor gene polymorphisms and risk of hip fracture in Chilean elderly women].

Background: Osteoporotic hip fractures are devastating events in older women. There is a genetic modulation of bone phenotypic parameters including bone density (BMD) and bone fragility fractures. Vitamin D receptor (VDR) gene polymorphisms explain a small part of the genetic influence on BMD, whereas their effect on fractures remains uncertain.
