• No breathlessness, no chest signs

❓ Q1a - DIAGNOSIS

• A) Typhoid fever
• B) Viral URTI (Common cold/Flu)
• C) Bacterial Pneumonia
• D) Dengue fever

❓ Q1b - LAB INVESTIGATION

• A) Blood culture
• B) CBC (Complete Blood Count)
• C) No investigations needed - clinical diagnosis
• D) Throat swab culture

💡 However, do a CBC if:

• Fever persists beyond 5-7 days
• Suspecting bacterial superinfection
• Patient is immunocompromised

• B) Oseltamivir (Tamiflu) immediately
• C) Symptomatic treatment - Paracetamol, antihistamine, steam inhalation + rest + hydration
• D) IV antibiotics and hospitalization

📋 Typical OPD Rx for Viral URTI:

• Paracetamol 500mg TDS (fever & body ache)
• Cetirizine 10mg OD (runny nose, sneezing)
• Steam inhalation BD
• Warm saline gargles (sore throat)
• Rest + adequate hydration
• Avoid antibiotics - no role in viral illness!
• Review if no improvement in 5-7 days

🏆 Case 1 Score: 3/3

🩺 Case 2

• Headache on and off for 2 months
• No chest pain, no vision changes
• BP today: 150/96 mmHg
• BP on last visit (2 weeks ago): 148/94 mmHg
• No known medical illness

❓ Q2a - DIAGNOSIS

• A) White coat hypertension
• B) Essential (Primary) Hypertension
• C) Hypertensive emergency
• D) Secondary hypertension due to renal disease

• Elevated BP on two separate visits
• Obese middle-aged male
• No obvious secondary cause

💡 HTN is diagnosed when BP ≥ 140/90 mmHg on 2 or more separate occasions

❓ Q2b - LAB INVESTIGATION

• A) No tests needed, just start medicines
• B) CBC, RFT, LFT, Urine routine, Fasting blood sugar, Lipid profile, ECG
• C) CT scan of brain
• D) Echocardiography and renal angiography

📋 Why each test?

• RFT - check kidney involvement
• Urine routine - proteinuria (renal damage)
• Fasting sugar - diabetes co-existing?
• Lipid profile - cardiovascular risk
• ECG - Left ventricular hypertrophy (LVH)
• CBC - baseline, rule out secondary causes

❓ Q2c - TREATMENT

• A) Start Amlodipine 5mg immediately + lifestyle changes
• B) Lifestyle modifications alone for 1-3 months, then reassess
• C) Start Furosemide immediately
• D) Refer to cardiologist before doing anything

🫘 Hypertension + Kidney Involvement (High Creatinine / CKD)

🔴 What changes in management:

⚠️ Important OPD pearls:

• If creatinine rises >30% after starting ACEi - suspect bilateral renal artery stenosis, stop the drug
• If K+ > 5.5 - stop ACEi/ARB, risk of hyperkalemia
• Refer to nephrologist if creatinine >2 mg/dL or eGFR <30

❓ Q2c - TREATMENT (original question)

• A) Start Amlodipine 5mg immediately + lifestyle changes
• B) Lifestyle modifications alone for 1-3 months, then reassess
• C) Start Furosemide immediately
• D) Refer to cardiologist before doing anything

📋 Lifestyle Modifications (OPD Counselling points):

• Salt restriction - <5g/day (avoid pickles, papad, processed food)
• Weight loss - even 5kg reduction drops BP by 5-10 mmHg
• Exercise - 30 min brisk walk, 5 days/week
• Stop smoking & alcohol
• DASH diet - fruits, vegetables, low-fat dairy
• Stress management

⚠️ Start medicines IMMEDIATELY (don't wait) if:

• BP ≥ 160/100 mmHg
• Diabetes present
• CKD present
• Already had heart attack or stroke

🏆 Case 2 Score: 3/3 | Total: 6/6 🎉

🩺 Case 3

• Increased thirst and frequent urination for 2 months
• Increased hunger, feeling tired
• Weight loss of 4 kg in 2 months
• Family history - father had diabetes
• BMI: 27 (overweight)

❓ Q3a - DIAGNOSIS

• A) Diabetes Insipidus
• B) Type 1 Diabetes Mellitus
• C) Type 2 Diabetes Mellitus
• D) Hyperthyroidism

💡 Classic symptoms = 3 Polys - Polyuria, Polydipsia, Polyphagia + weight loss + fatigue

❓ Q3b - LAB INVESTIGATION

• A) Random blood sugar only
• B) Urine sugar (glucosuria)
• C) Fasting plasma glucose ≥ 126 mg/dL on two occasions OR HbA1c ≥ 6.5%
• D) Post meal blood sugar once

💡 Hint: Think about which test confirms diagnosis vs. just screening!

📋 Diagnostic Criteria for Diabetes (WHO/ADA Guidelines):

⚠️ Why A is incomplete:

• Random blood sugar alone is not enough
• It needs to be ≥ 200 mg/dL WITH classic symptoms to diagnose
• In asymptomatic patients, you need two abnormal readings on separate days
• Random sugar can be affected by recent meals - not reliable alone

💡 In OPD practice:

• Best confirmatory test = Fasting glucose + HbA1c together
• HbA1c also tells you last 3 months control - very useful!
• Urine sugar (option B) is unreliable - renal threshold varies person to person

❓ Q3c - TREATMENT

• A) Insulin injections
• B) Glibenclamide (Sulphonylurea)
• C) Metformin + Lifestyle modifications
• D) Pioglitazone

📋 Why Metformin is preferred:

• Reduces hepatic glucose production
• No hypoglycemia risk (unlike sulphonylureas)
• Promotes mild weight loss
• Cardioprotective benefits
• Cheap & widely available
• Start at 500mg OD/BD with meals, increase gradually to 1000mg BD

⚠️ When to AVOID Metformin:

• Creatinine > 1.5 mg/dL (eGFR <30) - risk of lactic acidosis
• Heart failure (severe)
• Before contrast dye procedures - stop 48 hrs prior
• Alcoholism

💡 When to start Insulin directly:

• HbA1c > 10-11%
• Symptomatic hyperglycemia (very high sugars)
• Pregnancy
• Type 1 DM always

🏆 Case 3 Score: 2/3 | Total: 8/9

🩺 Case 4

• Burning sensation in chest/upper abdomen after meals
• Sour/bitter taste in mouth, especially on lying down
• Symptoms worse after tea, coffee, spicy food
• No weight loss, no difficulty swallowing
• Symptoms for 3 months, on and off

❓ Q4a - DIAGNOSIS

• A) Acute gastritis
• B) Peptic ulcer disease
• C) GERD (Gastroesophageal Reflux Disease)
• D) Gallstone disease

💡 Classic GERD features:

• Heartburn - burning behind sternum
• Regurgitation - sour/bitter taste in mouth
• Worse on - lying down, bending forward, after heavy meals
• Triggers - tea, coffee, alcohol, spicy food, chocolate, smoking
• Relieved by - antacids, sitting upright

⚠️ Red flag symptoms that need urgent endoscopy:

• Dysphagia (difficulty swallowing)
• Weight loss
• Hematemesis (vomiting blood)
• Age >45 with new onset symptoms

❓ Q4b - LAB INVESTIGATION

• A) Upper GI Endoscopy immediately
• B) Barium swallow X-ray
• C) No investigation needed - clinical diagnosis, give empirical treatment
• D) H. pylori breath test

📋 When to do Endoscopy:

• Age >45 with new symptoms
• Red flag symptoms present
• No response to PPI therapy after 4-8 weeks
• Recurrent/chronic GERD (to rule out Barrett's esophagus)

💡 H. pylori test (Option D) is done when suspecting peptic ulcer disease - not primary GERD

❓ Q4c - TREATMENT

• A) Antacids only (Gelusil/Digene) as needed
• B) PPI (Omeprazole 20mg) before breakfast for 4-8 weeks + lifestyle modifications
• C) H2 blocker (Ranitidine) only
• D) Immediate referral for surgery

📋 OPD Rx for GERD:

• Omeprazole 20mg (or Pantoprazole 40mg) - 30 min before breakfast
• Duration: 4-8 weeks for initial treatment
• Add Domperidone 10mg before meals if bloating/nausea present

💡 Lifestyle counselling (very important!):

• Avoid tea, coffee, alcohol, spicy & fatty food
• Elevate head end of bed by 6-8 inches
• Small frequent meals - avoid large meals
• No lying down for 2-3 hrs after eating
• Lose weight if overweight
• Stop smoking
• Avoid tight clothing around abdomen

⚠️ PPIs vs H2 Blockers:

• PPIs (Omeprazole, Pantoprazole) = more effective, preferred
• H2 blockers (Ranitidine/Famotidine) = mild cases or add-on at night
• Antacids alone = only for immediate symptomatic relief, not treatment

🏆 Case 4 Score: 3/3 | Total: 11/12 🎉

🩺 Case 5

• Itchy rash in the groin area for 2 weeks
• Ring-shaped lesion with central clearing
• Raised, scaly border
• Worsens in hot & humid weather

❓ Q5a - DIAGNOSIS

• A) Psoriasis
• B) Eczema (Atopic dermatitis)
• C) Tinea cruris (Fungal infection)
• D) Scabies

💡 Key differentiating features of Tinea:

Feature	Tinea	Eczema	Psoriasis
Border	Raised, scaly, active	Ill-defined	Well-defined, silvery
Central clearing	Yes	No	No
Itching	Yes	Intense	Mild-moderate
Trigger	Humidity, sweat	Allergens	Stress, trauma
Scraping	KOH positive	Negative	Negative

💡 Tinea at different locations:

• Groin = Tinea cruris
• Feet = Tinea pedis (Athlete's foot)
• Scalp = Tinea capitis
• Body = Tinea corporis
• Nails = Tinea unguium (Onychomycosis)

❓ Q5b - LAB INVESTIGATION

• A) Skin biopsy
• B) KOH (Potassium Hydroxide) mount of skin scraping
• C) Blood culture
• D) No test needed, treat empirically always
