Viral infections affecting the liver have had an important impact on humanity, as they have led to significant morbidity and mortality in patients with acute and chronic infections. Once an unknown etiology, the discovery of the viral agents triggered interest of the scientific community to establish the pathogenesis and diagnostic modalities to identify the affected population. With the rapid scientific and technological advances in the last centuries, controlling and even curing the infections became a possibility, with a large focus on preventive medicine through vaccination. Hence, a comprehensive understanding of hepatitis A, B, C, D and E is required by primary care physicians and gastroenterologists to provide care to these patients. The review article describes the epidemiology, pathogenesis, clinical presentation, diagnostic tools and current medication regimens, with a focus on upcoming treatment options and the role of liver transplantation.
Acute adult supraglottitis can be a serious, life-threatening disease because of its potential for sudden upper airway obstruction. Symptoms and signs of this disease may be nonspecific and may resemble those of upper respiratory tract infection. Unexplained sore throat with tenderness of the anterior neck over the hyoid bone warrant careful examination by flexible laryngoscopy to rule out laryngeal congestion and edema. Laboratory tests are usually not helpful in picking up the diagnosis. Following diagnosis, patients should be hospitalized, started on intravenous antibiotics and their airway closely monitored, as airway obstruction may develop.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
