⚠️ Toxic Shock Syndrome (TSS) is a life-threatening emergency 🆘. Patients can deteriorate within hours. Often triggered by 🩸 tampon use, 🤕 minor wounds, or 🏥 surgical packing. 💉 Early aggressive fluids + broad-spectrum antibiotics = survival. Look for 🚨 rash, diarrhoea, hypotension, altered mental status.

📖 About TSS

• 🧬 Superantigen-mediated → massive cytokine storm 🌊 → capillary leak + shock.
• ⏱️ Rapid onset → multi-organ failure if untreated.
• 🔗 Classic tampon link, but also wounds, burns, nasal packs, surgery.
• 📉 Mortality: ~2–5% with treatment; up to 30% if delayed or streptococcal.

🌍 Epidemiology

• Rare: ~1–3 cases / 100,000 per year.
• 🧑‍🦰 Classically menstruating women (tampons), but also 👶 children, 👨 men, 👵 elderly.
• 🟡 Staphylococcal TSS = more common; 🔴 Streptococcal TSS = more severe ⚡ (often with necrotising fasciitis).

🦠 Aetiology & Pathophysiology

⚠️ Risk Groups

• 🩸 Tampon use (esp. high absorbency, prolonged use).
• 🤕 Wounds, burns, skin infections.
• 🏥 Postoperative patients with retained packing.
• 🧒 Children post-varicella (risk of invasive Strep A).
• 🛡️ Immunocompromised or chronic illness.

📋 Case Definition (CDC)

🛠️ Management by Cause

📝 Exam Pearls

• Clindamycin = key (blocks toxin production) 💊.
• Rash + hypotension + multiorgan = think TSS 🚨.
• Remove tampon/packing FIRST before anything else 🔎.
• Strep TSS → always look for necrotising fasciitis 🦵.

🛡️ Prevention

• 🩸 Change tampons every 4–6h; alternate with pads at night.
• 🚫 Avoid very high absorbency tampons unless needed.
• 🧼 Strict wound care; remove packing promptly.
• 📢 Education for patients on early red flag symptoms.

🧑‍⚕️ Case Examples - Toxic Shock Syndrome (TSS)

• Case 1 (Menstrual-related TSS): 🩸 A 23-year-old woman presents with sudden high fever, vomiting, diarrhoea, and diffuse erythematous rash. She is hypotensive (BP 80/50), tachycardic, and confused. She has been using a high-absorbency tampon for >24 hours. Analysis: Classic menstrual-related TSS due to Staphylococcus aureus toxin release. Diagnosis: Clinical - fever, hypotension, rash, multi-organ involvement. Management: Immediate resuscitation with IV fluids, remove tampon, IV clindamycin + flucloxacillin, ICU support if shock persists. IVIG in refractory cases.
• Case 2 (Post-surgical TSS): 🏥 A 45-year-old man develops fever, diffuse rash, hypotension, and acute renal failure 5 days after orthopaedic surgery. Wound looks relatively clean. Analysis: Non-menstrual TSS, typically due to Staphylococcus aureus or Streptococcus pyogenes. Local infection may look mild, but systemic toxin effect is profound. Diagnosis: Sepsis with shock + rash + multiorgan involvement in a post-surgical patient. Management: Broad-spectrum IV antibiotics (including clindamycin to inhibit toxin production), surgical wound review/debridement, aggressive fluid resuscitation, vasopressors if refractory.
• Case 3 (Streptococcal TSS with necrotising fasciitis): ⚠️ A 36-year-old woman presents with severe leg pain, fever, hypotension, and rapidly spreading erythema after a minor cut while gardening. Exam shows swelling, blistering, and crepitus. Analysis: Streptococcal TSS complicating necrotising fasciitis. Toxin-mediated vasodilation and cytokine storm cause shock and multi-organ failure. Diagnosis: Fulminant soft-tissue infection with systemic shock and rash. Management: Emergency surgical debridement, IV clindamycin + carbapenem, IV fluids, vasopressors, ICU care. Consider IVIG.
