Abstract

To evaluate the knowledge of physicians prescribing CT examinations on the radiation protection of patients.A questionnaire was distributed to all clinicians on medical staff who prescribe CT examinations. Several questions related to their prescription pattern and their knowledge of radiation protection.Forty-four questionnaires were analyzed. While 70% of physicians claimed that they considered the risks from exposure to ionizing radiation when prescribing a CT examination, only 25% informed their patients about those risks. Knowledge of the radiation dose delivered during CT evaluation of the abdomen and pelvis was poorly understood and the risks related to small doses of radiation were grossly underestimated. Finally, only a third of clinicians had received training with regards to radiation protection.While most clinicians claim that they consider the risks from exposure to ionizing radiation when prescribing a CT examination, the risks are either not well known or not known at all. Increased formation of clinicians with regards to the radiation protection of patients, maybe through a dedicated clinical rotation while in medical school, could be a solution to improve the knowledge of hospital clinicians with regards to radiation protection.

2. [Pyomyositis of adductor muscles caused by Escherichia coli in an immunocompetent patient living in a temperate climate]

Abstract

Pyomyositis is a primitive infection of the skeletal muscle usually caused by Staphylococcus aureus in tropical areas, and associated with immunodeficiency. We report a 49-year-old immunocompetent woman, living in a temperate climate presenting with a pyomyositis of adductor muscles caused by Escherichia coli. Diagnosis was obtained with magnetic resonance imaging (MRI). Disease course was uneventful after surgical debridement and antibiotics. This case report highlights the usefulness of MRI in the diagnosis of pyomyositis.
