Lithium: acute overdose is usually benign if adequate hydration is maintained and renal function is normal; chronic toxicity can be difficult to manage and result in devastating neurotoxicity
CLASS MECHANISM OF ACTION (1) low concentrations: methylene blue -> NADPH-dependent reduction to leucomethylene blue (due to action of methaemoglobin reductase) -> reduces methaemoglobin -> Hb(2) high concentrations: methylene blue -> converts ferrous iron of reduced Hb to ferric ion…
Hilar lymphadenopathy, seen on chest x-ray or chest CT, can be classified as unilateral or bilateral, and if bilateral as symmetrical or asymmetrical.
OVERVIEW In general terms, validity is “the quality of being true or correct”, it refers to the strength of results and how accurately they reflect the real world. Thus ‘validity’ can have quite different meanings depending on the context! Reliability…
