Paediatrics: Meningitis B: Free MSRA Podcast

⚕️ FREE MSRA PODCAST – Meningitis B: High-Yield Paediatric Revision🎧 Essential audio revision for MSRA, GP trainees, and anyone working with paediatric emergencies.🧠 Key Learning Points📌 Definition• Meningitis B is a life-threatening bacterial infection caused by Neisseria meningitidis serogroup B. It leads to inflammation of the meninges (protective membranes covering the brain and spinal cord), particularly affecting infants, children, and young people.📌 Causes & Epidemiology• Neisseria meningitidis serogroup B is spread via respiratory droplets and close contact (e.g. household, school, dormitory outbreaks).• Other bacterial causes of meningitis depend on age:– Neonates: Group B strep (GBS), E. coli, Listeria– Children/Teens: N. meningitidis (B, C, W, Y), S. pneumoniae, Hib– Elderly/Immunosuppressed: S. pneumoniae, N. meningitidis, Listeria• Incidence has decreased with the UK MenB vaccine, but bacterial forms remain high risk due to severity.📌 Risk Factors• Close contact with an infected person• Crowded environments (schools, universities, nurseries)• Age (infants and young children are most vulnerable)• Immunocompromised state• Asplenia (no or poor spleen function), chronic illness• Recent upper respiratory tract infection📌 Clinical Features• Classic triad: Fever, neck stiffness, headache• Other: Photophobia, vomiting, altered mental state, seizures• Rash: Non-blanching petechial or purpuric rash (“glass test” – does not fade under pressure)• Red flags: Cold extremities, limb pain, abnormal skin colour, prolonged capillary refill, irritability (especially in infants)• Infants: Poor feeding, irritability, bulging fontanelle, high-pitched cryREMEMBER: Septicemia (meningococcal sepsis) may present without classic meningitis signs. Non-blanching rash and shock are critical warning features.📌 Differential Diagnosis• Viral meningitis (more common, less severe)• Other bacteria (see above), TB meningitis• Encephalitis• Intracranial abscess• Subarachnoid haemorrhage• Non-infective causes (malignancy, autoimmune, drugs)📌 Diagnosis• Immediate clinical diagnosis – don’t delay treatment for tests• Lumbar puncture (if safe): CSF for WCC, Gram stain, culture, glucose/protein, PCR• Blood cultures and PCR• FBC, CRP, coagulation screen• Imaging (CT/MRI) if raised intracranial pressure suspected• Notify public health for confirmed/suspected cases📌 Management• Urgent hospital admission• Immediate IV antibiotics (age-specific):– <3 months: IV amoxicillin (+/- gentamicin) + cefotaxime– ≥3 months: IV ceftriaxone or cefotaxime• Dexamethasone: Consider if ≥3 months (not in younger children)• Supportive care: Fluids, oxygen, treat shock, correct metabolic issues, monitor for raised intracranial pressure• Isolation and public health notification• Antibiotic prophylaxis for close contacts (ciprofloxacin preferred in the UK)📌 Prognosis & Complications• Early recognition & prompt antibiotics = best chance of survival• Mortality is high without treatment• Up to 30–50% of survivors may have long-term sequelae:– Hearing loss (deafness)– Neurological deficits (seizures, paralysis, cranial nerve palsies)– Developmental delay, learning difficulties– Limb loss (in severe sepsis)• Prevention is key: UK MenB vaccination📚 Full Meningitis B MSRA Resources:📝 Revision Notes: https://www.passthemsra.com/topic/meningitis-b-revision-notes/🧠 Flashcards: https://www.passthemsra.com/topic/meningitis-b-flashcards/💬 Accordion Q&A: https://www.passthemsra.com/topic/meningitis-b-accordion-qa-notes/🚀 Rapid Quiz: https://www.passthemsra.com/topic/meningitis-b-rapid-quiz/🎓 Full Course: https://www.passthemsra.com/courses/paediatrics-for-the-msra/#MSRA #MeningitisB #MSRARevision #Paediatrics #GPRevision #MSRAFlashcards #MSRAQuiz #MSRAAccordions #ChildHealth #MeningococcalDisease #Meningitis #NICEGuidelines #VaccinesSaveLives
