MTD 🩺

A patient develops sudden loss of central vision. Fundoscopy is shown. What's the diagnosis? A. Retinal detachment B. Central retinal artery occlusion C. Central retinal vein occlusion D. Acute glaucoma

A child has a port-wine stain over the face and recurrent seizures. What is the diagnosis? A. Tuberous sclerosis B. Sturge-Weber syndrome C. Neurofibromatosis type 1 D. Von Hippel-Lindau disease

What's this TRIAD? 🚨

What's this TRIAD? 🚨

🩺 "Wet, Wobbly, Wacky" is the classic mnemonic for Normal pressure hydrocephalus: • Wet → Urinary incontinence • Wobbly → Gait disturbance (magnetic gait) • Wacky → Cognitive impairment/dementia The classic triad is: Gait disturbance (usually the earliest symptom) Urinary incontinence Dementia Brain imaging typically shows ventriculomegaly with normal CSF pressure. Symptoms may improve after CSF drainage or ventriculoperitoneal shunting.

What's this TRIAD? 🚨

✅ Answer: C. Exogenous glucocorticoid useCushing syndrome is most commonly caused overall by prolonged use of glucocorticoid medications.Key distinction: • Most common overall cause of Cushing syndrome: Exogenous glucocorticoid use • Most common endogenous cause: Pituitary ACTH-secreting adenoma (Cushing disease)❌ Pituitary adenoma — most common endogenous cause, not overall. ❌ Adrenal adenoma — less common. ❌ Ectopic ACTH production — classically from Small-cell lung cancer, but less common.✅ Exogenous glucocorticoid use.

The most common cause of Cushing syndrome is:

✅ Answer: B. Clostridioides difficile infection Clostridioides difficile infection is the most common cause of pseudomembranous colitis, typically occurring after antibiotic use due to overgrowth of C. difficile and production of toxins A and B. ❌ Salmonella — causes inflammatory diarrhea but not pseudomembranous colitis. ❌ Escherichia coli — may cause watery or bloody diarrhea depending on the strain. ❌ Shigella — causes dysentery with bloody diarrhea. ✅ Clostridioides difficile infection.

The most common cause of pseudomembranous colitis is:

✅ Answer: B. Phenylketonuria Phenylketonuria is caused by deficiency of phenylalanine hydroxylase (or tetrahydrobiopterin deficiency), leading to accumulation of phenylalanine. Classic features: • Fair skin and light-colored eyes • Musty/mousy body odor • Intellectual disability if untreated • Eczema ❌ Alkaptonuria — dark urine and ochronosis. ❌ Maple syrup urine disease — sweet "maple syrup" urine odor. ❌ Homocystinuria — marfanoid habitus, lens subluxation (downward), thrombosis. ✅ Phenylketonuria (PKU).

A child has fair skin, blue eyes, and a musty body odor. What is the most likely diagnosis?

✅ Answer: D. Diffuse esophageal spasm A corkscrew esophagus on barium swallow is the classic radiographic finding of Diffuse esophageal spasm, caused by uncoordinated, simultaneous esophageal contractions. ❌ Esophageal carcinoma — typically causes an irregular narrowing or obstructing mass. ❌ Achalasia — shows a bird-beak appearance at the lower esophageal sphincter. ❌ Esophageal web — appears as a thin membranous narrowing, usually in the upper esophagus. ✅ Diffuse esophageal spasm — classic corkscrew appearance.

A patient complains of progressive difficulty swallowing. Barium swallow is shown. What is the diagnosis? A. Esophageal carcinoma B. Achalasia C. Esophageal web D. Diffuse esophageal spasm

✅ Answer: A. Aortic dissection The patient most likely has Marfan syndrome. The most feared cardiovascular complication is aortic root dilation with subsequent aortic dissection, which is the major cause of death. ❌ Coarctation of the aorta — more commonly associated with Turner syndrome. ❌ Mitral stenosis — classically linked to Rheumatic fever. ❌ Restrictive cardiomyopathy — not a typical complication of Marfan syndrome.

A 25-year-old man develops sudden chest pain. He is tall with long fingers and hypermobile joints. What is the most feared cardiovascular complication?

@MTDMED ☢️ MI

The cardiac marker that remains elevated for the longest duration after MI is:

@Kababhadu 👏🌟

@MTDMED Myoglobin 1–4 hours 6–12 hours 24 hours (shortest) CK-MB 4–6 hours 12–24 hours 48–72 hours (2–3 days) Troponin I/T 4–8 hours 12–48 hours 7–14 days (up to 21 days in some cases) LDH (total) 6–12 hours 3–4 days 8–14 days (less specific)

@AskRezzy 👏👏

Answer: Troponin T 🧪⭐ ★ It rises within hours after myocardial infarction ⏰ ★ It remains elevated for about 10-14 days 📅 ★ It persists longer than CK-MB 📈 ★ Helpful when the patient presents late 🚑 ★ Troponin I also rises but clears sooner ↘️ ★ Always interpret with ECG and symptoms 📋 #USMLE #Cardiology #MedEd Find more such high-yield points: oncourse.onelink.me/xW0t/install

@MTDMED 👉C.Troponin T

@PharmWise Perfect!

@MTDMED C. Troponins, they are the most sensitive and the longest-lasting markers after MI.
