For moderate-to-severe PCP, either clindamycin-primaquine or pentamidine may be administered. However, pentamidine generally does not cause hemolytic anemia. +
Atherosclerotic plaques are rich in extracellular matrix and smooth muscle cells. Foam cells are macrophages that engulf oxidized low-density lipoproteins by endocytosis via scavenger receptors and form the fatty streaks of atheroma in the tunica intima of arteries. +
Although fibrocalcific plaque with thickening of the coronary intima may be associated with nonocclusive thrombus, it does not typically cause symptoms of unstable angina. +
Cholangiocytes are the epithelial cells of the bile duct. They are cuboidal epithelium in the small interlobular bile ducts, but become columnar and mucus secreting in larger bile ducts approaching the porta hepatis and the extrahepatic ducts. +
Anti-U1-RNP antibody does not target hnRNA. The snRNP combines with hnRNA to form spliceosome and undergoes splicing. +
Anti-Sm antibody is specific for SLE. Smith antigen is a group of proteins (B/D/E/F/G) without snRNA; it is metabolized by trypsin but not by RNase. +
IV steroids are used in clinical practice by neurosurgeons and often administered empirically if cauda equina is suspected, however this is not the first step in management. +
Incorrect- This drug should not be avoided as it does not have extrapyramidal side effects. +
Deformation is extrinsic disruption of an organ or tissue; it occurs after the embryonic period. +
Infection with the Rubella virus is associated with the development of a descending rash and post-auricular lymphadenopathy. +
Smooth muscle contraction of the ductus arteriosus results from the activation of the G-coupled prostaglandin receptor EP4 by PGE2 (not PGF2). +
Incorrect- It is not an essential part of physical examination for a newly diagnosed patient with hypertension. +
The Golgi apparatus is a distribution center of proteins and lipids from the endoplasmic reticulum to the plasma membrane, lysosomes, and secretory vesicles. +
Incorrect- Meningococcemia, like many gram-negative blood infections, can cause disseminated intravascular coagulation (DIC), which is the inappropriate clotting of blood within the vessels. DIC can cause ischemic tissue damage when upstream thrombus obstructs blood flow and haemorrhage because clotting factors are exhausted. But normal PT and PTT findings exclude this as a possibility. +
