Clinical predictors of significant intracranial computed tomography scan findings in adults experiencing headache disorder.

Introduction: Radiological assessments for adult headache disorder show significant intracranial findings in 2.5% to 10% of performed computed tomography scans (CT-scans), leading to an overuse consideration for CT-scan requests by physicians in headache-experiencing patients. Therefore, we undertook this study in order to determine predictors of significant intracranial CT-scan findings in adults experiencing headache disorder; in order to help physicians better select patients who need imaging, which would subsequently decrease the costs of headache disorder management and the useless irradiation rates.

Sero-epidemiology of human immunodeficiency virus, hepatitis B and C viruses, and syphilis infections among first-time blood donors in Edéa, Cameroon.

Background: Blood safety remains an issue of major concern in transfusion medicine in sub-Saharan Africa. Blood-borne agents such as the human immunodeficiency virus (HIV), hepatitis B virus (HBV), hepatitis C virus (HCV), and Treponema pallidum are among the greatest threats to blood safety for the recipient. This study aimed to determine the seroprevalence and risk factors of HIV, HCV, HBV, and syphilis infections among first-time blood donors at the new hospital-based blood bank in Edéa, Cameroon.
