Randomized Controlled Trial Clinical TrialPhysician attitudes towards evidence-based medicine in eastern Saudi Arabia.
Because of the growing awareness of the limitations of traditional information on clinical decisions, there is a shift in medical practice towards evidence-based medicine (EBM). ⋯ There was an overall positive attitude among physicians towards EBM. There was a proportional relation between the knowledge of EBM and attitude towards it. Dissemination of the EBM concept and practice among physicians is highly recommended.

Non-traumatic cerebrospinal fluid rhinorrhea: diagnosis and management.
Although the majority of cerebrospinal (CSF) fistulas in the anterior skull base are traumatic in nature, the minority is non-traumatic or primary. Non-traumatic CSF leak can be a diagnostic and treatment challenge. ⋯ Non-traumatic CSF rhinorrhea is a relatively rare condition and occurs secondary to different etiologies. Among multiple techniques available for localization, MRI/FLAIR is effective, but requires further evaluation and polishing. In the absence of a large skull base lesion or tumor, endoscopic repair of CSF fistula carries a high success rate with a high margin of safety and low morbidity rate.

The etiology of preeclampsia remains obscure. To study the role of insulin resistance in preeclampsia, we compared fasting insulin and glucose changes during the second and third trimesters in preeclamptic women with a normal control group. ⋯ Women who develop preeclampsia have higher insulin levels before clinical evidence of disease than women who remain normotensive during pregnancy. The increase in insulin levels in the third trimester was greater in preeclamptic than in non-preeclamptic women.
