Obgyn: Syphilis: Free MSRA Podcast

⚕️FREE MSRA PODCAST –Syphilis (STI)🎧 A complete, structured deep dive into theUK-focused diagnosis, stages, management, and public health implications ofsyphilis — made memorable and exam-ready for the MSRA.🧠Key Learning Points📌Definition• Syphilis is a sexually transmitted infection caused by Treponema pallidum• It progressesthrough four stages: primary, secondary,latent, and tertiary, each with distinct features• Also transmissiblemother-to-baby → congenital syphilis📌Causes & RiskFactors• Direct contactduring vaginal, anal, or oral sex• Verticaltransmission in pregnancy• Key risk factors:– Unprotected sex– Multiple sexualpartners– History of otherSTIs– MSM (Men who havesex with men)📌Pathophysiology• Bacteria entersvia mucosal surfaces or skin breaks• Spreads via blood and lymphatics, rapidly becoming systemic• Drives multi-stageprogression and organ involvement📌Symptoms by Stage🦠Primary• Painless genital chancre with clean base• May also appear onlips, fingers, anus🦠Secondary• Occurs ~6 weekslater• Generalised rash (often palms/soles), lymphadenopathy, fever• Condylomata lata – raised, wart-like infectiouslesions• Possible patchyalopecia, uveitis, meningitis, hepatitis🦠Latent• No symptoms, butinfection remains• Early latent = <2 years, late latent = >2 years🦠Tertiary• Neurosyphilis: tabes dorsalis, dementia,meningovascular complications• Cardiovascular: aortic regurgitation, aneurysms• Gummatous syphilis: rubbery granulomas in skin,liver, bone• Congenital syphilis risk if mother untreated📌Epidemiology (UKFocus)• Tripled incidence in England over past decade• Highest in MSM, urban areas,and Black communities• Notifiable disease: must report to publichealth authorities📌Investigations🧪Treponemal tests:• Detect exposure(EIA, TPHA, TPPA) – often stay positive for life🧪Non-treponemal tests:• Reflect activity(RPR, VDRL) – used for treatment monitoring🧪Direct detection:• Dark fieldmicroscopy, PCR, DFA from lesions🧪Lumbar puncture: for suspected neurosyphilis💡Mnemonic:• Treponemal = Touchedbacteria (exposure)• Non-treponemal = Nowactive (disease)📌Management• Refer to GUM clinics (sexual health)• First-line: IM benzathinepenicillin (single dose for early syphilis)• Alternative: Doxycyclineif allergic• Late latent: 3 weekly penicillin injections• Neurosyphilis: High-dose procaine penicillin + probenecid (CNSpenetration)• Pregnancy: Penicillin preferred —desensitisation if allergic🧠Jarisch–Herxheimerreaction• Febrile reactionwithin 24h of treatment• Not allergy –manage with paracetamol/NSAIDs💡Mnemonic: P = Penicillin as primarytreatment, D = Doxycycline for those with penicillin allergy📌Public Health• Partner notification and contact tracing crucial• Treat contactspre-emptively to break transmission• Routine antenatal screening prevents congenitalcases📌Complications• Neurosyphilis – sensory loss, dementia• Cardiovascular syphilis – valvular damage,aortic aneurysm• Gummatous lesions – destructive organ nodules• Congenital syphilis – severe neonatal disease📌Prognosis &Prevention• Excellent with early diagnosis and treatment• Untreated → irreversible damage• Prevent with condom use, regular screening, and early partnertreatment📎More MSRA Resourcesfor Syphilis📝 Revision Notes: https://www.passthemsra.com/topic/syphilis-revision-notes/🧠 Flashcards: https://www.passthemsra.com/topic/syphilis-flashcards/💬 Accordion Q&A Notes: https://www.passthemsra.com/topic/syphilis-accordion-qa-notes/🚀 Rapid Quiz: https://www.passthemsra.com/topic/syphilis-rapid-quiz/🎓 Full Course: https://www.passthemsra.com/courses/obstetrics-and-gynaecology-for-the-msra/#MSRA#MSRARevisionNotes #MSRATextbook #MSRAQuiz #MSRAQuestionBank #MSRAFlashcards#MSRAQANotes #MSRAAccordions #MultiSpecialityRecruitmentAssessment#MSRAOnlineRevision #MSRARevisionWebsite #Syphilis #STI #TreponemaPallidum
