🔴Phenytoin- It is a widely used antiepileptic drug & is the most frequent cause of drug-induced gingival hypertrophy or overgrowth. • Approximately 50% of patients on phenytoin develop gum enlargement, especially in the anterior gingiva. ∆ Pathogenesis- Stimulation of gingival fibroblasts leading to excessive collagen accumulation. • Severity is influenced by dose, duration, oral hygiene & genetic predisposition. ∆ C/F- Gingival hypertrophy is painless but may cause cosmetic issues, difficulty chewing & increase risk of periodontal disease. ✓T/t- Meticulous oral hygiene, possible drug substitution & surgical excision in severe cases. ∆ Other drugs causing gingival hypertrophy- Cyclosporine (immunosuppressant) & calcium channel blockers (e.g., nifedipine) but less commonly.

Patient with epilepsy has gingival hyperplasia👇 👉 What is the most likely culprit?

💠Thyroglossal cyst- It is a congenital neck cyst arising from persistent thyroglossal duct remnants. It is the M/C congenital neck cyst in children & adults. ∆ C/F- An usually painless, midline neck swelling that moves with swallowing or tongue protrusion, may become infected, leading to swelling, tenderness, redness & sometimes fistula formation, can cause speech/swallowing difficulty if large. ✓ Dx- Clinical, USG/CT scan to confirm location & relation to hyoid bone, fine needle aspiration/biopsy may be performed if diagnosis is uncertain. ∆ T/t- Sistrunk procedure= Removal of the cyst along with the middle part of the hyoid bone & tract to prevent recurrence.

🩺❓Painless, smooth, cystic midline neck mass that moves upward with tongue protrusion or swallowing… Diagnosis?

Cushing's syndrome. ∆ Pathophysiology- Excess glucocorticoids (endogenous/exogenous) cause fat redistribution (truncal > peripheral), collagen breakdown (striae), protein catabolism (muscle wasting), and insulin resistance (hyperglycemia). • Central obesity, moon face, and buffalo hump are characteristic for Cushing's syndrome.

What is the Diagnosis? What is the cause of lower back pain?

B. ≥90 mm Hg. Sublingual nitroglycerin is a potent arteriolar and venodilator; it rapidly lowers preload and afterload, which can cause hypotension and reduced coronary perfusion in already low‑BP patients. Because of this, it is contraindicated in severe hypotension, and most guidelines state it should not be given when SBP is <90 mm Hg or when there is signs of shock (e.g., severe bradycardia, severe anemia, inferior MI with RV involvement).

Sublingual nitroglycerin should be used only if systolic blood pressure is: A. ≥80 mm Hg B. ≥90 mm Hg C. ≥100 mm Hg D. ≥110 mm Hg

✳️ Necrobiosis Lipoidica. • Etiology- F > M, usually 3rd–4th decade. ∆ Complications- M/C→Ulceration, Rare → Squamous cell carcinoma in chronic ulcers. ∆ Management- Control of diabetes, Topical/intralesional corticosteroids (first-line for active lesions), Tacrolimus, PUVA therapy, antiplatelet drugs (aspirin, pentoxifylline) may help, Surgical grafting for refractory ulcerated lesions.

Uncontrolled diabetic patient with this painless lesions. What is it?

@SameerYogi14 You are absolutely spot on. Thanks a ton for your input.

@MedLearnHub C ). Chlamydia trachomatis

Which is the Most common organism causing pelvic inflammatory disease ? A) Neisseria gonorrhoeae. B) Staphylococcus aureus. C) Chlamydia trachomatis. D) E. coli.

C) Azithromycin+antihistamine. Azithromycin and certain antihistamines are well-known to cause prolonged QT interval by blocking cardiac potassium channels, potentially leading to life-threatening Torsades de Pointes. This is because both drug classes independently delay ventricular repolarization, creating a dangerous synergistic effect on the heart's electrical rhythm.

Prolonged QT interval. Cause ❓ A) Ondansetron + Tramadol B) Sildenafil + Nitrates C) Azithromycin + Antihistamine D) Furosemide + Gentamicin #MedX ?

@USMLE_Step2_Pro Yes. That's right. Thanks a lot for your answer.

@MedLearnHub C. Chlamydia trachomatis ✅

@Doctors_GUILD D. Myoglobin. Myoglobin is the earliest to rise and Troponin is the most specific one.

A 55-year-old man presents with chest pain for 4 hours. ECG is inconclusive. Which of the following cardiac biomarkers rises earliest after myocardial infarction? A. CK-MB B. Troponin I C. LDH D. Myoglobin

A. Epiglottitis- It is an acute, rapidly progressive, life-threatening inflammation of the epiglottis & surrounding supraglottic structures causing airway obstruction. • Causative organism- M/C= Haemophilus influenzae type b (Hib) • Age group- It is Common in 2–6 years (unvaccinated). ∆ C/F- High fever, Extremely Severe sore throat, Dysphagia, odynophagia, drooling, Muffled "hot-potato" voice, Stridor, respiratory distress. • Classic posture- Tripod or sniffing position. ✓ Dx- Clinical, Radiological sign: "Thumb sign" on lateral neck X-ray. 🚫Do NOT examine throat with tongue depressor- It can cause complete obstruction. ∆ T/t- TOC = Secure airway & IV ceftriaxone. • Prevention- Hib vaccine. • D/d- Croup (laryngotracheobronchitis)– It has barking cough & steeple sign, whereas epiglottitis has drooling & thumb sign.

A Child with sore throat develops neck swelling and dyspnea. Lateral neck X-ray shows “thumb sign”. Diagnosis? A) Epiglottitis B) Croup C) Retropharyngeal abscess D) Diphtheria

@DrMedica_13 Thank you so much for your valuable inputs.

@MedLearnHub Both A and C

B. Chloramphenicol. ✴️Gray baby syndrome- It is a life-threatening reaction to the antibiotic chloramphenicol in newborns, especially premature infants. • Reason- It occurs because infants have immature liver enzymes that can't metabolize chloramphenicol leading to drug accumulation & toxicity. ∆ C/F- Main features are gray or ashen skin color, vomiting, abdominal distention, low blood pressure, cyanosis & respiratory distress. ∆ T/t- Early recognition & stopping the drug are essential; supportive care is needed to prevent fatal outcome.

WHICH DRUG IS ASSOCIATED WITH GRAY BABY SYNDROME?

@MoarSahitoPTI Thank you so much Doctor.

@MedLearnHub Perfect absolutely right.

A patient presents with high fever, severe headache, and neck stiffness, suggesting acute bacterial meningitis. 💉 Empirical drug of choice.? 🤔 A) Ceftriaxone B) Metronidazole C) Ciprofloxacin D) Azithromycin

B) H. Pylori. Helicobacter pylori is the primary etiological agent of peptic ulcer disease, accounting for approximately 70% of gastric and over 90% of duodenal ulcers globally. Long-term NSAID use remains the second most common cause, while factors like stress and alcohol act as significant exacerbators rather than primary initiators.

Most common cause of peptic ulcer disease? A) NSAIDs B) H. pylori C) Stress D) Alcohol

D. Hypoglossal nerve. • Cranial dura mater receives somatic sensory innervation mainly from-: Trigeminal nerve (CN V)– especially its meningeal branches (V1, V2, V3) to supratentorial dura and middle cranial fossa. • Upper cervical nerves (C1–C3)– via meningeal branches covering the posterior cranial fossa and dura around the foramen magnum. • Vagus nerve (CN X) – via its meningeal branch supplying some infratentorial dura (posterior cranial fossa). •Hypoglossal nerve (CN XII) is a pure motor nerve for intrinsic and extrinsic tongue muscles and does not supply the dura.

Sensory supply of dura is all except? A. Trigeminal nerve B. Cervical nerve C. Vague nerve D. Hypoglossal nerve

E. Continuous. A Patent Ductus Arteriosus (PDA) produces a continuous, "machinery-like" murmur because the pressure in the aorta remains higher than the pulmonary artery throughout both systole and diastole. This persistent pressure gradient causes a constant left-to-right shunt, creating a sound that peaks in late systole and continues through the second heart sound into diastole.

What type of murmur is heard throughout systole and diastole and caused by a patent ductus arteriosus 💔 ❓ A. Mid-diastolic B. Pansystolic C. Early diastolic D. Ejection systolic E. Continuous
