Introduction Organophosphate poisoning is a potentially life-threatening condition caused by exposure to organophosphate (OP) compounds. These agents irreversibly inhibit acetylcholinesterase, leading to the accumulation of acetylcholine and overstimulation of cholinergic receptors. Etiology Sources: Agricultural pesticides (e.g., malathion, parathion). Chemical warfare agents (e.g., sarin, VX gas). Ophthalmologic agents for glaucoma (e.g., echothiophate, isoflurophate). Accidental exposure or […]
Introduction: Ventricular septal defect (VSD) is a hole in the wall that separates the right and left ventricles of the heart, resulting in shunt formation. – They are the most prevalent congenital cardiac anomaly in children and the second most common in adults, surpassed only by bicuspid aortic valves. Etiology: can occur with other congenital […]
Introduction: Patent ductus arteriosus (PDA) is a persistence of the in utero communication between the aortic and pulmonary arteries after birth causing a left-to-right shunt. Risk factors: Maternal rubella infection; prematurity; high altitude, genetic problems such as Down syndrome Pathophysiology: In the fetal circulation, superior vena cava blood enters the right atrium and characteristically […]
from www.supertestscores.com Introduction: Familial hypercholesterolemia (FH) is a group of autosomal dominant and recessive disorders of lipoprotein metabolism characterized by strikingly elevated low-density lipoprotein-cholesterol (LDL-C), the presence of xanthomas, and premature atherosclerosis. Epidemiology: Homozygous 1 in 1 million; Heterozygous 1 in 500 Pathogenesis: Pathogenic variations in the following four genes can cause FH: (1) […]
