Anuria in children may arise from a host of causes and is a frequent concern in the emergency department. This review focuses on differentiating common causes of obstructive and nonobstructive anuria and the role of point-of-care ultrasound in this evaluation. We discuss some indications and basic techniques for bedside ultrasound imaging of the urinary system.
Esophageal motor abnormalities are currently categorized into separate entities based on standard manometry. The clinical significance of these categories is controversial. We evaluated whether ambulatory 24-h esophageal motility monitoring improves the assessment of patients thought to have a primary esophageal motor disorder. Standard and ambulatory 24-h esophageal motility records of 30 heal...
We thank Dr. de Araújo Gonçalves and colleagues for their interest in our study (1), which acknowledges the strong relationship of atherosclerotic plaque characteristics (APCs), as imaged by coronary computed tomography angiography (CTA), to lesionspecific ischemia. They express concerns regarding the limits of spatial resolution by coronary CTA. Current scanners possess approximately 500-mm is...
OBJECTIVES The aim of this study was to evaluate the effects of losartan on left ventricular (LV) hypertrophy and fibrosis in patients with nonobstructive hypertrophic cardiomyopathy (HCM). BACKGROUND Despite evidence that myocardial hypertrophy and fibrosis are mediated by angiotensin II and are important determinants of morbidity and mortality in patients with HCM, no prior studies have eva...
INTRODUCTION According to guidelines, the diagnosis of COPD should be confirmed by post-bronchodilator (post-BD) airway obstruction on spirometry; however, in clinical practice, this is not always performed. The aim of this population-based study was to compare clinical characteristics and prognosis, assessed as mortality, between subjects with airway obstruction divided into pre- but not post-...
