background: coronary arteriovenous fistulas (cavfs) are direct connections from one or more coronary arteries to cardiac chambers or a large vessel. they are mostly of congenital origin. the aim of this study was to describe clinical presentation and also delineate the course and management of cavf. methods: clinical data, chest x-rays, echocardiographic and angiographic evaluation of 40 patien...
Background: Vaginal epithelium is the most important site for initial contact of the parasite infection in humans. Objective: To investigate the effect of Lactobacillus acidophilus (LA) and pH on attachment of T. vaginalis isolated from symptomatic and asymptomatic patients to vaginal epithelial cells (VECs). Methods: Following 1-4 hrs contact of parasite with VECs, wet mounts were prepared and...
PURPOSE This study quantified the overall effects of aortic valve disease (AVD) and mitral valve disease (MVD) by disease severity on direct health-care costs to insurers and patients. MATERIALS AND METHODS Based on 1996-2011 data from the Medical Expenditure Panel Survey (MEPS), a large, nationally representative US database, multivariate analyses were performed to assess the relationship be...
BACKGROUND AND PURPOSE The introduction of CAS has led to increased treatment of both symptomatic and asymptomatic patients with internal carotid stenosis. This study was performed to compare the effect of stent placement on cerebral perfusion in symptomatic and asymptomatic patients using CT perfusion. MATERIALS AND METHODS We included 45 patients with carotid artery stenosis of ≥70% who und...
The circulating anti-parasite antibody response against Giardia lamblia in symptomatic and asymptomatic Egyptian children with confirmed giardiasis was examined. Symptomatic patients were identified using the following criteria: presence of only G. lamblia cysts in the feces, and one or more of the following symptoms, diarrhea, abdominal pain, loss of weight, vomiting and/or nausea, and abdomin...
INTRODUCTION This study aimed to examine the incidence, epidemiology, and clinical characteristics of symptomatic and asymptomatic candidiasis in a pediatric intensive care unit (PICU), and to determine the risk factors associated with symptomatic candidiasis. METHODS This retrospective study included 67 patients from a 7-bed PICU in a tertiary care hospital that had Candida-positive cultures...
Introduction: In spite of the fact that acute otitis media is a systemic and symptomatic disease with sever otalgia, otitis media with effusion (OME) is an asymptomatic and silent disease.

Results: Among 1001 children under study, 57 subjects (5.7%) were dia...
BACKGROUND AND PURPOSE von Willebrand factor propeptide (VWF:Ag II) is potentially a more sensitive marker of acute endothelial activation than von Willebrand factor antigen (VWF:Ag). These biomarkers have not been simultaneously assessed in asymptomatic versus symptomatic carotid stenosis patients. The relationship between endothelial activation and cerebral microembolic signals (MESs) detecte...
Human rhinovirus (HRV) infections are common but poorly characterized in university students. Thus, we characterized asymptomatic and symptomatic HRV infections by incidence, species diversity, and viral load of 502 university students during September and October of 2010 and 2011 from nasal swabs and electronically submitted symptom questionnaires. We tested all symptomatic students and random...
