[Detection of ionizing radiation in operating room and hospital areas].

Background: The implementation of new medical techniques and technologies has increased occupational exposure to ionizing radiation and consequently the development of neoplasia and adverse effects on health personnel.

Objective: Have real information on the absorbed dose by healthcare personnel exposed to ionizing radiation in an operating room.

Material And Methods: TLD 100 dosimeters were used to measure absorbed doses by brightness curves.

Evaluation of micronuclei in oral mucosa of individuals exposed to ionizing radiation: a pilot study from Celaya, México.

Introduction: Occupational exposure to ionizing radiation can potentially lead to adverse health effects, including cancer and genetic defects. Genetic damage caused by radiation can be detected if micronuclei are observed. The objective of this pilot study was to detect the presence of micronuclei in cells of the oral mucosa in inidividuals occupationally exposed to ionizing radiation.

Validity and reliability of electroacoustic probe for diagnosis of developmental dysplasia of the hip.

Background: Sound transmission is used in the diagnosis of hip dysplasia since the end of the 80's. Aim of this study is to quantify the validity and reliability of electroacoustic probe for the diagnosis of hip dysplasia in neonates.

Methods: Diagnostic study included neonates aged 4-28 days, whose parents signed an informed consent.
