Mnemonic: ABCD
Mnemonic: PPM
Malnourished (depleted intracellular Phosphate, Potassium, Magnesium) → Refeeding → Increased glucose load → Insulin spikes → Drives PPM into cells → Hypophosphatemia (major abnormality), hypokalemia, hypomagnesemia
If patient hasn’t not eaten for >5 days, aim to refeed at <50% energy and protein levels.
Monitor and aggresively supplement PPM.
Concentric layers of Granuloma There are 4 concentric layers in a granuloma, however the clear distinction is difficult in reality due to overlapping. From inside to out: 1. Necrosis Caseating necrosis: Tuberculosis, Leprosy Coagulative necrosis: Buruli ulcer (M.ulcerans), Gumma containing central blood vessels (Syphilis) Fibrinoid necrosis: Aschoff bodies (Rheumatic granuloma),…
Pes Anserinus is composed of the combination of tendinous insertions of the sartorius, gracilis and semitendinosus muscles (guy ropes muscles) which attaches to the medial side of tibia to generate a “goose’s foot” like appearance. These three muscles are mainly flexors of the knee but also have a role in…
Zero-order First-order Amount of drug eliminated per unit time Constant amount Constant fraction (Mnemonic: first = fraction) Rate of elimination with plasma concentration Independent Directly proportional (greater the drug, greater is elimination) Elimination Capacity-limited, i.e. liver/kidney are saturated/maxed out on how much they can eliminate Flow-limited, i.e. liver/kidney are not…
