ENT: Allergic Rhinitis: Free MSRA Podcast

✅ MSRA Deep Dive: Allergic Rhinitis – More Than Just SneezingIn this high-yield episode, we unpack the essential MSRA revision notes on allergic rhinitis, a highly prevalent yet often underestimated condition. From its pathophysiology to red flags and NICE-guideline-based management, we turn dense content into a memorable, focused review — ideal for exam prep or quick clinical refresh.🧠 Key Learning Points📌 Definition & Classification• Allergic rhinitis is nasal mucosa inflammation triggered by airborne allergens (pollen, dust mites, animal dander)• Symptoms include: sneezing, nasal congestion, runny nose, itchy nose/eyes/throat• Classified as:Seasonal (e.g. pollen/hay fever)Perennial (e.g. dust mites)Occupational (e.g. chemical exposure at work)📌 Causes & Risk Factors• Caused by type 1 hypersensitivity reaction (IgE-mediated mast cell degranulation)• Two phases: Immediate (histamine-driven) & late-phase (6–12h after exposure)• Risk factors:Family history of atopyPersonal history of asthma or eczemaUrban living (pollution)Environmental triggers (dust, pets, mold)📌 Associated Conditions• Often occurs with conjunctivitis, eczema, asthma, rhinosinusitis, nasal polyps• Asthma link: Poorly controlled rhinitis may worsen asthma control📌 Differential Diagnosis• Non-allergic rhinitis, infective rhinitis, sinusitis, nasal polyps, deviated septum• Red flags:Unilateral watery rhinorrhoea → consider CSF leakUnilateral obstruction, pain, bleeding → consider nasal neoplasm📌 Diagnosis & Investigations• Clinical history is key — especially symptom timing, triggers• Skin prick test: first-line• Specific IgE blood tests: second-line (RAST/ELISA)• Imaging (CT) only for resistant cases or red flags• Nasal airflow tests (e.g. peak nasal inspiratory flow) used in select cases📌 Management Overview🔹 1. Allergen Avoidance• Tailored to trigger: e.g. dust mites (year-round), pollen (seasonal)🔹 2. Medications• Mild: Oral or intranasal antihistamines• Moderate/severe: Intranasal corticosteroids (e.g. fluticasone)• Add-ons:Montelukast (esp. with asthma)Ipratropium nasal spray (for runny nose)Nasal saline irrigation• Short-course oral steroids for severe flares• Topical decongestants: max 5–7 days to avoid rebound congestion🔹 3. Immunotherapy (desensitisation)• SCIT (injections) or SLIT (sublingual)• Indicated for severe allergic rhinitis unresponsive to medication• Commitment: typically 3 years, suitable from age 5+🔹 4. Surgery• Reserved for structural issues (e.g. septal deviation, nasal polyps)• May include turbinate reduction or functional endoscopic sinus surgery📌 Prognosis & Complications• Most cases respond well to treatment• Some resolve over time – up to 20% may outgrow seasonal rhinitis• If untreated, can lead to:Poor sleep, fatigue, school/work disruptionWorsening asthmaChronic sinusitis, nasal polyps, otitis media in children🔗 Allergic Rhinitis MSRA Resources📄 Notes: https://www.passthemsra.com/topic/allergic-rhinitis-revision-notes/💬 Flashcards: https://www.passthemsra.com/topic/allergic-rhinitis-flashcards/🧠 Q&A Notes: https://www.passthemsra.com/topic/allergic-rhinitis-accordion-qa-notes/📝 Quiz: https://www.passthemsra.com/topic/allergic-rhinitis-rapid-quiz/🎓 Full Course: https://www.passthemsra.com/courses/ent-for-the-msra/🏷️ Hashtags#MSRA #MSRAQuiz #MSRAFlashcards #MSRAQandA #MSRARevisionNotes #ENT #AllergicRhinitis #MSRAENT #PassTheMSRA #FreeMSRA #NICEguidelines #Atopy #AsthmaLink #HayFever
