Source notes: where the sources differ or are ambiguous
- Heat illness columns. Source: slide groups exertional heat-stroke features (CNS dysfunction, rhabdomyolysis, renal failure, coagulopathy) with a core temperature < 40 °C under “heat exhaustion”. Taught here: Heat exhaustion is < 40 °C without major CNS dysfunction; heat stroke is > 40 °C with CNS dysfunction, classic (elderly, anhidrosis) or exertional (young, may still sweat). L6 p.20
- B12 methylmalonate arrow. Source: the B12 diagram draws methylmalonic acid → methylmalonyl-CoA. Taught here: Physiologically propionyl-CoA → methylmalonyl-CoA → succinyl-CoA (mutase needs B12); methylmalonic acid accumulates from methylmalonyl-CoA when the mutase lacks B12. L6 p.45
- Radiation syndrome thresholds. Source: dose bands overlap and place the cerebral syndrome at 10 Gy. Taught here: Thresholds are approximate and sources differ; the neurovascular (cerebral) syndrome generally needs tens of Gy. Higher doses add the lower-dose effects. L6 p.26
- Obesity genetics. Source: “genetic factors account for 5–10% of obesity; metabolic syndrome is one example.” Taught here: Monogenic obesity is rare, but heritability of body weight is substantial; metabolic syndrome is a cluster of risk factors, not a genetic cause. L6 p.35
- Vitamin K toxicity in newborns. Source: lists neonatal hemolysis and kernicterus as vitamin K toxicity. Taught here: This applies to synthetic menadione (K₃); natural phylloquinone (K₁), given as prophylaxis, is safe. L6 p.41
- Simulation Q31 bicarbonate. Source: stem gives serum HCO₃⁻ 8 mEq/L; the correct answer option shows HCO₃⁻ 14. Taught here: Option D (pH 7.29, PaCO₂ 30, HCO₃⁻ 14) is still the only primary metabolic acidosis with appropriate respiratory compensation (Winter's formula predicts PaCO₂ ≈ 29 for HCO₃⁻ 14). The reused option table causes the mismatch. Midterm sim. p.12–13
Brief in the sources, expanded here as supporting context
- Puncture/stab wounds and the labels of the three gunshot photos (contact, intermediate-range stippling, exit) are not written on the slides; added from standard forensic terminology.
- Acetaminophen mechanism (NAPQI, glutathione, zone 3, NAC) is one line on L6 p.10; detail comes from L1 p.22 and Robbins.
- Disulfiram, xeroderma pigmentosum, refeeding syndrome, leptin resistance, Menkes disease, Hartnup disease, carcinoid and isoniazid as niacin causes, HAPE/HACE, hepatic adenoma are added from standard references; the lecture names them only briefly or in a diagram.
- Pantothenic acid (B5) appears only on the vitamin overview slide; its coenzyme-A role is supporting context.
- Mineral and electrolyte excess/deficiency beyond trace metals (syllabus) is taught in Chapter 4 and linked, not repeated.
- Simulation Q31 is primarily a Chapter 4 acid–base item; it is mapped here for the ethylene glycol content and links back to Chapter 4.
