A farmer with pinpoint pupils, salivation, fasciculations — organophosphorus poisoning; atropine + pralidoxime. OP poisoning (SLUDGE — salivation, lacrimation, urination, defecation, GI, emesis + miosis, fasciculations, bronchorrhea): atropine (dries secretions — titrated) + pralidoxime (reactivates cholinesterase) + decontamination. Snakebite — neurotoxic (krait/cobra — ptosis, respiratory paralysis — ASV + ventilation) vs hemotoxic (viper — bleeding, coagulopathy — ASV + blood products); pressure immobilization, no tourniquet/incision. Paracetamol (NAC <8h — nomogram). Geriatrics — atypical (MI as confusion, UTI as falls): comprehensive assessment, deprescribe (Beers), falls/delirium prevention. The pinpoint pupil is cholinergic — atropine dilates the treatment.
