AIM To assess the role of breast ultrasonography as a complement to negative mammography in radiologically dense breasts. MATERIAL AND METHODS Out of a total series of 49,044 consecutive mammograms reported as negative in asymptomatic women, 25,665 (52.3%) were coded as dense (BI-RADS D3-4) and ultrasonography was recommended. Due to organizational problems, ultrasonography was performed imme...
BACKGROUND The Asymptomatic Carotid Atherosclerosis Study (ACAS) showed that carotid endarterectomy was beneficial for symptom-free patients with carotid stenosis of 60% or more. This finding raises the question of whether widespread screening to identify cases of asymptomatic carotid stenosis should be implemented. OBJECTIVE To determine whether a screening program to identify cases of asymp...
STUDY OBJECTIVE Symptoms associated with pulmonary embolism can be nonspecific and similar to many competing diagnoses, leading to excessive costly testing and treatment, as well as missed diagnoses. Objective studies are essential for diagnosis. This study evaluates the cost-effectiveness of different diagnostic strategies in an emergency department (ED) for patients presenting with undifferen...

BACKGROUND Counselling for Alcohol Problems (CAP), a brief intervention delivered by lay counsellors, enhanced remission and abstinence over 3 months among male primary care attendees with harmful drinking in a setting in India. We evaluated the sustainability of the effects after treatment termination, the cost-effectiveness of CAP over 12 months, and the effects of the hypothesized mediator '...
One strategy was compression ultrasonography, followed by anticoagulation in case of positive results (high probability ventilation-perfusion (VQ) scans) or by VQ scan or spiral computed tomography (CT) in case of negative results. Low probability VQ scans resulted in no treatment, whereas high probability VQ scans resulted in anticoagulation. Intermediate tests were followed by a second test (...
Collaboration among investigators, centers, countries, and disciplines is essential to advancing the care for traumatic brain injury (TBI). It is thus important that we "speak the same language." Great variability, however, exists in data collection and coding of variables in TBI studies, confounding comparisons between and analysis across different studies. Randomized controlled trials can nev...
BACKGROUND Screening for alcohol use disorders identifies a wide range of needs, varying from hazardous and harmful drinking to alcohol dependence. Stepped care offers a potentially resource-efficient way of meeting these needs, but requires evaluation in a randomised controlled trial. AIMS To evaluate the feasibility, effectiveness and cost-effectiveness of opportunistic screening and a step...
