13	Complete Management Algorithm - Full flowchart: presentation → investigation → viral/bacterial decision → Paradise criteria → surgery → follow-up
14	References - Bailey & Love, Scott-Brown, KJ Lee, Cummings, NPTA, SIGN guidelines

Key Clinical Content Highlights

Investigations:

Blood: CBC (neutrophilia = bacterial; lymphocytosis + 10% atypicals = EBV), ESR, CRP, Monospot (85% sensitive, 100% specific), ASO titre, pre-op coagulation profile, blood crossmatch
Urine: R/E for pre-op screen + post-streptococcal GN detection (haematuria, proteinuria), urine βHCG pre-GA
Special: Throat swab C&S, RADT (rapid antigen detection), CT neck for abscess, biopsy for asymmetric tonsil, polysomnography for OSA

Medical Treatment:

Penicillin G → Penicillin V oral step-down (1st line GABHS)
Macrolide (Clarithromycin) for penicillin allergy
Dexamethasone single dose for severe oropharyngeal oedema
Paracetamol + NSAIDs for analgesia
Never Ampicillin/Amoxicillin in EBV (causes diffuse rash)

Surgery - Tonsillectomy:

Consent → GA + Boyle-Davis gag → Rose position → anterior pillar incision → sub-capsular blunt dissection → lower pedicle division → bipolar haemostasis / ligation → bilateral → lateral (tonsillar) position for extubation
Cold steel + ties = gold standard (lowest secondary bleed at 1.0%)

Post-op Instructions in both English and Marathi covering diet, pain, activity restrictions, danger signs for bleeding, and follow-up.
