🧠 Prenatal Detection of a Ganglionic Eminence Cyst at 19 Weeks – Clinical Significance and Management 🧠 In this 19-week fetal neurosonography case, there is a cystic structure localized to the region of the ganglionic eminence(GE), an uncommon and often incidental finding during second-trimester scans. 🧠 The GE plays a key role in neuronal migration and cortical development, raising important questions when a cyst is identified in this region. 🧠 Ganglionic eminence cysts are rare, usually benign lesions thought to represent variants of normal neurodevelopment. They are typically transient, non-progressive, and are often resolved or no longer visible in follow-up imaging during the third trimester or postnatally. 👉 However, when such a finding is observed, it’s crucial to: ● Confirm its location and characteristics via multiplanar imaging. ● Rule out associated anomalies, especially midline or migrational abnormalities (is it isolated?). ● Recommend targeted follow-up scans, typically around 28–32 weeks. ● Consider fetal MRI if there is diagnostic uncertainty or if other brain abnormalities are suspected. 🧠 In isolated cases, the prognosis is generally excellent, and the cysts do not impact neurodevelopmental outcomes. 🧠 I’m sharing this video to highlight the importance of careful evaluation of subtle fetal brain findings and to encourage discussion around the appropriate workup and counseling in such scenarios. 🧠 Have you encountered similar cases in your practice? I’d be happy to hear your thoughts. 👉 Thanks for the case Reyhan Ayaz #FetalUltrasound #Neurosonography #PrenatalDiagnosis #GanglionicEminence #MaternalFetalMedicine #UltrasoundEducation #CaseStudy

Dexamethasone Use in Late Pregnancy Dexamethasone is a synthetic corticosteroid commonly used in late pregnancy to promote fetal lung maturity when preterm delivery is anticipated. Why Dexamethasone is Used • Fetal lungs are immature before 37 weeks, with insufficient surfactant production. • Dexamethasone (or betamethasone) accelerates surfactant synthesis, reducing the risk of: • Respiratory distress syndrome (RDS). • Intraventricular hemorrhage. • Neonatal death. Indications • Threatened preterm labor (between 24–34 weeks, sometimes up to 36 weeks). • Preterm premature rupture of membranes (PPROM). • Elective preterm cesarean section. Dosage (Antenatal Corticosteroid Therapy) • Dexamethasone 6 mg IM every 12 hours for 4 doses (total 24 mg). OR • Betamethasone 12 mg IM every 24 hours for 2 doses. Benefits • Reduces incidence and severity of neonatal RDS. • Decreases neonatal mortality. • Reduces risk of intraventricular hemorrhage and necrotizing enterocolitis. Precautions • Use with caution in maternal infections (can mask symptoms). • In diabetics, it can cause hyperglycemia (may need insulin adjustment). • Not routinely repeated unless >14 days have passed since the first course and delivery risk persists. Other Uses in Pregnancy • Treatment of fetal conditions like congenital adrenal hyperplasia (CAH) (rare indication). • Management of severe maternal conditions requiring steroids (e.g., severe COVID-19 in pregnancy).

EARLY SURGERY IN ASYMPTOMATIC MITRAL REGURGITATION: LESSONS FROM LONG-TERM DATA ⏳ The timing of surgery in severe mitral regurgitation remains one of the most debated questions in valvular heart disease. 📊 Circulation has now reported long-term data on 1,000+ asymptomatic patients with severe degenerative MR: ✔️ Early surgery = safe (0 operative deaths, 97% repair rate). ✔️ Survival benefit at 20 years = significant (cardiac death 5.6% vs 17.4%). Study design • 1,063 patients with severe degenerative MR and preserved LV function (1996–2016). • Early surgery (545) vs conventional management (518). • Median follow-up: 12 years; 358 pairs matched by propensity score. Results • Cardiac mortality reduced by >70% with early surgery (1.5% vs 10.4%). • Overall survival significantly improved (HR 0.66). • 20-year data: cardiac death 5.6% vs 17.4%; overall mortality 28.2% vs 33.9%. • Safety: 0 operative deaths, 97% repair rate. ✅ “No symptoms” does not mean “no risk.” Early referral can change long-term outcomes ❤️ How do you define the right threshold for intervention in asymptomatic severe MR in your practice? 📚 Source: Circulation, 2025.

🧠 Medical Insight: Anesthesia vs Euthanasia 🧠 Understanding the difference between Anesthesia and Euthanasia is not just important for healthcare professionals, but also for every informed individual. 🔹 Anesthesia – A reversible procedure to relieve pain during medical operations. 🔹 Euthanasia – An irreversible decision aimed at ending suffering through medically induced death. This visual simplifies a sensitive yet vital topic that often causes confusion. As a pharmacy student, I believe it’s essential to spread accurate and responsible knowledge. 📌 Let’s promote clarity in medical terminology. #PharmacyStudent #MedicalKnowledge #Anesthesia #Euthanasia #PharmaAwareness #HealthcareEducation #Prince

The post-cam design of the PS prosthesis should consider a lower post-cam contact position while avoiding square designs with small spacing between the post and the intercondylar groove of the femoral component and recommending a round post design. https://lnkd.in/gGbX4jHb
