OMDR vs Pharma — Key differences for NEET MDS
Pemphigus = INTRAepithelial Tzanck cells fishnet DIF. Pemphigoid = SUBepithelial linear DIF. Erythema multiforme = target lesions iris lesions = drug hypersensitivity. Stevens-Johnson syndrome = severe mucocutaneous EM. Dermatitis herpetiformis = celiac disease associated. Epidermolysis bullosa = genetic blistering = absent collagen VII.

Onset determined by pKa = lower pKa faster onset. Duration determined by protein binding = higher binding longer duration. Articaine = unique hybrid amide with ester group. Prilocaine = least toxic amide. Bupivacaine = most cardiotoxic.
