Pyloric Stenosis (Hypertrophic Pyloric Stenosis)

Definition & Epidemiology

• Incidence: ~1 in 250-300 live births
• Sex: Males affected 4-5x more than females (>80% of cases in males)
• Age of onset: Presents between 3-6 weeks of life (range 2-10 weeks); rare after 12 weeks; peak incidence at ~5 weeks
• Risk factors: First-born child, white race, positive family history, premature birth, young maternal age
• Genetic component: High concordance in monozygotic twins; genome-wide studies have linked several GI development genes; siblings of affected patients have ~6% risk (vs. ~0.2% general population)
• Associated conditions: Turner syndrome, trisomy 18 confer increased risk

Pathophysiology

---

Clinical Presentation

---

Metabolic Abnormalities

Hypochloremic, hypokalemic, hyponatremic metabolic alkalosis

• Mechanism: Loss of HCl in vomit → chloride depletion → kidneys retain bicarbonate → alkalosis. Potassium is lost both in vomit and via renal exchange for hydrogen ions as the kidney attempts to maintain acid-base balance (paradoxical aciduria in a setting of alkalosis).
• A bicarbonate >30 mEq/L indicates severe alkalosis and is a contraindication to anesthesia (risk of postoperative apnea/respiratory arrest).

---

Diagnosis

Ultrasound (Gold Standard)

• Pyloric muscle wall thickness ≥ 4 mm
• Pyloric channel length ≥ 16-17 mm
• Failure of fluid to pass through the pylorus during the exam

• "Shoulder sign": Hypertrophic muscle bulging into the gastric antrum
• "Nipple sign": Double-layered hypertrophic mucosa protruding into the stomach
• "Cervix sign": Overall sonographic appearance resembling the uterine cervix
• Abnormal, exaggerated peristaltic waves visible in real time

Upper GI Series (UGI)

---

Management

Step 1 - Resuscitation First (NOT an emergency operation)

1. IV fluid resuscitation: 1-2 boluses of 20 mL/kg normal saline
2. Maintenance fluids: D5/0.45% NaCl with KCl at 1.5x maintenance rate
3. Monitor electrolytes every 6-12 hours

• Wet diapers (adequate urine output)
• Serum chloride: 90-100 mEq/L
• Serum bicarbonate: ≤30 mEq/L

Step 2 - Surgical Repair: Ramstedt Pyloromyotomy

• Laparoscopic pyloromyotomy is now the preferred approach (3 ports: umbilical + two 3-mm stab incisions)
• The pyloric muscle is incised longitudinally and split from stomach to duodenum, leaving mucosa intact
• A leak test (30-60 mL air via OG tube) confirms mucosal integrity
• Post-op: ad lib feeding with 60 mL limit; most infants discharged within 36 hours

Complications of Pyloromyotomy

---

Acquired Pyloric Stenosis (Adults)

• Antral gastritis or peptic ulcers near the pylorus
• Carcinoma of the distal stomach or pancreas (fibrosis or malignant infiltration)

Q.2 (ii) — Pyloric Stenosis: Complete Exam Answer

---

1. DEFINITION

• It is NOT a congenital defect - the pylorus is normal at birth and enlarges postnatally
• It is the most common cause of surgical GI obstruction beyond the first month of life
• Incidence: 1 in 250-300 live births
• Male-to-female ratio: 4:1 (males predominantly affected)
• Ramstedt pyloromyotomy is the definitive surgical cure

---

2. ETIOLOGY & RISK FACTORS

---

3. PATHOPHYSIOLOGY

Normal pylorus at birth
        ↓
Postnatal hypertrophy of pyloric muscularis propria (circular > longitudinal)
        ↓
Pyloric canal becomes progressively narrowed and elongated
        ↓
Gastric outlet obstruction
        ↓
Stomach contents cannot pass → forceful (projectile) vomiting
        ↓
Loss of HCl in vomit → ↓ Cl⁻, ↓ H⁺
        ↓
Kidneys conserve H⁺, excrete K⁺ → ↓ K⁺
        ↓
HYPOCHLOREMIC, HYPOKALEMIC METABOLIC ALKALOSIS
        ↓
Dehydration, malnutrition, failure to thrive

---

4. CLASSICAL FEATURES (Clinical Presentation)

A. History

• Age of onset: 3-6 weeks (range 2-10 weeks); rare after 12 weeks
• Progressive, projectile, non-bilious vomiting - begins as mild regurgitation and escalates to forceful vomiting after every feed
• Vomit contains undigested milk, gastric secretions - never green/bilious (obstruction is above the ampulla of Vater)
• "Hungry vomiter" - infant vomits but immediately wants to feed again (ravenous appetite)
• Weight loss, poor weight gain, failure to thrive

B. Physical Examination Signs

C. Laboratory Findings (Electrolytes)

D. Ribbon-Like / Currant Jelly Stool?

• Note: In Q.1(viii) of your paper, "ribbon-like stool" is associated with anorectal malformation (not pyloric stenosis). Pyloric stenosis causes vomiting, not stool abnormalities.

---

5. DIAGNOSIS

A. Ultrasound (Gold Standard)

• Sensitivity and specificity up to 98% and 100%
• Diagnostic criteria:
  • Pyloric muscle thickness ≥ 4 mm
  • Pyloric channel length ≥ 16-19 mm
  • Pyloric diameter > 14 mm
  • Failure of fluid to pass through pylorus
• Special US signs: Shoulder sign, Nipple sign, Cervix sign

B. Upper GI Series (Barium Study)

• Used when US is equivocal
• Classic finding: "String sign" - thin streak of barium through narrowed pylorus
• Shows delayed gastric emptying and distended stomach
• Plain X-ray: gas-filled, distended stomach with paucity of gas in distal bowel

C. Complete Metabolic Panel

• Confirms hypochloremic, hypokalemic metabolic alkalosis
• Bicarbonate >30 mEq/L = contraindication to anesthesia (risk of post-op apnea)

---

6. SURGICAL MANAGEMENT

STEP 1 - PRE-OPERATIVE RESUSCITATION (MANDATORY - NOT a surgical emergency)

• IV Normal Saline (0.9%) bolus: 20 mL/kg (repeat 1-2 times as needed)
• Maintenance fluids: D5/0.45% NaCl + KCl at 1.5x maintenance rate
• Monitor electrolytes every 6-12 hours
• Potassium supplementation: KCl 0.5-1 mEq/kg IV over 1-2 hours if needed

• Wet diapers (adequate urine output)
• Serum Chloride: 90-100 mEq/L
• Serum Bicarbonate: ≤ 30 mEq/L
• Potassium: within normal range

• Nasogastric tube insertion for gastric suction (reduces aspiration risk at induction)
• Stomach must be suctioned immediately before anesthesia

---

STEP 2 - SURGICAL PROCEDURE: RAMSTEDT PYLOROMYOTOMY

1. Laparoscopic (currently preferred) - 3 incisions: 1 umbilical port + 2 lateral 3-mm stab incisions
2. Open - Right upper quadrant (RUQ) transverse incision or periumbilical incision

1. Infant placed supine under general anesthesia
2. Pylorus is identified and stabilized with a grasper
3. A longitudinal incision is made through the anterior wall of the pyloric canal (through serosa and muscle only - NOT into mucosa)
4. Muscle fibers are split (spread apart) from the stomach end to the duodenal end
5. Bulging mucosa should be visible beneath - confirms complete myotomy
6. Leak test performed: 30-60 mL air injected via orogastric tube; confirms:
   • Air passes freely through pylorus
   • No air escapes through mucosa (no perforation)
7. Wound closure

---

STEP 3 - POST-OPERATIVE CARE

• Feeding protocol: Start with clear liquids/half-strength formula 4-6 hours post-op; advance to full feeds; ad lib feeding with 60 mL limit initially
• Apnea monitoring: Post-op apnea is a known risk (especially if HCO₃ was elevated pre-op); monitor with pulse oximetry and apnea monitor
• Analgesia: Local infiltration of wound + paracetamol (acetaminophen)
• Discharge typically within 36 hours after tolerating at least 2 consecutive feeds

Q.2 ESSAY TYPE QUESTIONS (2 × 15 = 30 Marks)

---

Q.2 (i) — Congenital Heart Diseases: Definition, Classification, Cyanotic Spell Management (15 Marks)

---

A. DEFINITION

• Incidence: 8-10 per 1000 live births
• CHD is the most common congenital malformation worldwide
• About 1 million babies are born with CHD annually worldwide

---

B. ETIOLOGY / RISK FACTORS

---

C. CLASSIFICATION OF CONGENITAL HEART DISEASES

---

GROUP 1: ACYANOTIC (Left-to-Right Shunt / No Shunt)

---

GROUP 2: CYANOTIC (Right-to-Left Shunt)

---

D. MANAGEMENT OF CYANOTIC SPELL (TET SPELL / HYPERCYANOTIC EPISODE)

• Sudden onset of increased cyanosis
• Hyperpnea (rapid, deep breathing)
• Agitation, irritability, then limpness
• Loss of consciousness/seizures in severe cases
• Disappearance of the heart murmur (no blood flowing through RVOT)
• SpO₂ drops sharply

IMMEDIATE MANAGEMENT OF CYANOTIC SPELL:

• Place child in knee-chest position (squat position) or hold infant with knees drawn to chest
• This increases systemic vascular resistance (SVR), reduces right-to-left shunt, and increases pulmonary blood flow
• In infants: hold in knee-to-chest position against nurse's/mother's shoulder

• Administer 100% oxygen via face mask
• Helps increase alveolar oxygen tension and reduces hypoxic pulmonary vasoconstriction

• 0.1-0.2 mg/kg IV/SC
• Suppresses respiratory center, reduces hyperpnea, relaxes RVOT spasm, reduces catecholamines

• IV Normal Saline 10-20 mL/kg bolus
• Increases preload and improves cardiac output

• 1-2 mEq/kg IV for metabolic acidosis
• Corrects acidosis, which worsens the spell

• 0.01-0.1 mg/kg IV slowly
• Relaxes RVOT spasm, decreases heart rate, increases diastolic filling

• 0.02 mg/kg IV
• Increases SVR, reduces right-to-left shunt

Q.3 SHORT NOTES — ANY FIVE (5 × 5 = 25 Marks)

---

(a) Side Effects of Chemotherapy

SIDE EFFECTS BY SYSTEM:

• Neutropenia (↓ WBC) → Increased infection risk, fever, sepsis
• Thrombocytopenia (↓ Platelets) → Bleeding, bruising, petechiae

NURSING MANAGEMENT OF CHEMO SIDE EFFECTS:

---

(b) Refractory Errors (Errors of Refraction)

TYPES:

• Light focuses IN FRONT of retina
• Child can see NEAR objects clearly but FAR objects are blurred
• Eye is too long or cornea too curved
• Correction: Concave (diverging) lenses / spectacles

• Light focuses BEHIND the retina
• Child can see FAR objects but NEAR objects are blurred
• Eye is too short or cornea too flat
• Correction: Convex (converging) lenses / spectacles

• Irregular curvature of the cornea/lens
• Light focuses at multiple points → blurred/distorted vision at ALL distances
• Often coexists with myopia or hypermetropia
• Correction: Cylindrical (toric) lenses

• Age-related loss of near-vision (lens becomes rigid)
• Not relevant in children

SIGNS OF REFRACTORY ERRORS IN CHILDREN:

• Squinting/screwing up eyes to see clearly
• Sitting very close to TV/board
• Headaches, eye strain, rubbing eyes
• Difficulty reading, poor school performance
• Head tilting

MANAGEMENT:

• Corrective lenses (spectacles) - first-line treatment for all refractive errors in children
• Contact lenses (in older children/adolescents)
• Orthoptic exercises for associated squint/amblyopia
• Surgical correction (LASIK) - only after eye is fully developed (post-18 years)
• Amblyopia treatment: patching the good eye to force use of weaker eye

NURSING ROLE:

• School vision screening programs
• Educate parents on importance of proper lighting
• Encourage regular eye checkups from age 3
• Support child with glasses (prevent bullying)
• Ensure glasses are worn regularly; teach care of spectacles

---

2. CONTINUED FEEDING

• Do NOT withhold feeds (fasting is harmful)
• Continue breastfeeding throughout
• Resume age-appropriate diet as soon as tolerated
• BRAT diet (Bananas, Rice, Applesauce, Toast) if needed

3. ZINC SUPPLEMENTATION

• Under 6 months: 10 mg/day for 14 days
• Over 6 months: 20 mg/day for 14 days

6. NURSING MANAGEMENT:

---

(d) Extrophy of Bladder (Bladder Exstrophy)

CLINICAL FEATURES:

• Bladder mucosa is exposed, everted on the lower abdominal wall
• Continuous leakage of urine from the exposed bladder
• Epispadias (urethra opens on dorsal/upper surface of penis in males) - almost always associated
• Wide separation of pubic bones (diastasis pubis)
• Short, broad penis in males; bifid clitoris in females
• Umbilicus displaced downward
• Increased risk of recurrent UTI
• Social and psychological issues

COMPLICATIONS:

• Recurrent UTI
• Renal damage
• Bladder carcinoma (if not repaired)
• Infertility
• Psychosocial issues

MANAGEMENT:

1. Primary closure within 48-72 hours of birth (before pubic bones separate further)
   • Abdominal wall and bladder are closed
2. Bladder neck reconstruction (to achieve urinary continence)
3. Epispadias repair (urethroplasty) at 6-12 months
4. Osteotomy of pelvis (if closure done after 72 hours) to bring pubic bones together

• Monitor urinary output via urethral catheter
• Prevent infection (strict aseptic technique, antibiotics as ordered)
• Skin care around stoma/exposed area to prevent excoriation
• Splint legs to prevent pulling on surgical site
• Pain management
• Parent education and emotional support

---

(e) Temper Tantrums in Children

CAUSES / REASONS:

• Developmental stage: Toddlers want independence but lack language skills to express needs/frustration
• Tiredness, hunger, boredom
• Change in routine
• Overstimulation
• Being told "No" or not getting what they want
• Sensory issues (in some children with ASD/developmental delay)

SIGNS AND BEHAVIOR DURING TANTRUM:

• Crying, screaming, yelling
• Throwing objects
• Kicking, biting, hitting
• Holding breath (breath-holding spell)
• Rolling on floor, arching back
• Refusing to move

MANAGEMENT:

1. Remain calm - do not shout or punish
2. Ensure safety - remove dangerous objects
3. Ignore the tantrum if safe (not giving attention reinforces that tantrums do not work)
4. Do NOT give in to the demand (reinforces behavior)
5. Stay nearby but do not engage until child calms
6. Offer comfort after the tantrum ends (not during)

1. Maintain consistent routine (sleep, meals)
2. Give limited choices ("Do you want red shirt or blue shirt?" - gives sense of control)
3. Praise good behavior (positive reinforcement)
4. Avoid situations known to trigger tantrums (hunger, fatigue)
5. Use simple, clear language
6. Time-out technique: 1 minute per year of age in a safe, boring place

• Reassure parents that tantrums are normal developmental behavior
• Teach consistent, calm responses
• Advise NOT to use physical punishment
• Refer for assessment if tantrums are very severe, prolonged (>15 min), or associated with self-harm
• Evaluate for underlying developmental disorders (ASD, ADHD) if atypical

Q.4 VERY SHORT NOTES — ANY FOUR (4 × 2 = 8 Marks)

---

(a) Wilms Tumor (Nephroblastoma)

• Definition: Most common solid renal tumor of childhood; arises from primitive metanephric cells (embryonic kidney precursors)
• Age: Peak presentation in the 3rd year of life (2-5 years); no sex predilection
• Incidence: ~5% of all childhood cancers; ~650 new cases/year in USA
• Genetics: WT1 gene mutation on chromosome 11p13; associated with WAGR syndrome (Wilms tumor, Aniridia, Genitourinary malformation, mental Retardation), Beckwith-Wiedemann syndrome
• Presentation: Large, asymptomatic smooth abdominal mass (found by parent while bathing); abdominal pain, hematuria, hypertension, fever, nausea
• Important: DO NOT PALPATE the mass aggressively (risk of tumor capsule rupture and spread)
• Diagnosis: Ultrasound, CT abdomen, chest X-ray (for lung metastases)
• Treatment: Surgery (nephrectomy) + Chemotherapy (Actinomycin D + Vincristine) ± Radiotherapy
• Prognosis: Excellent - overall survival 90% with modern treatment

---

(b) Sunset Sign

• Definition: The "Sunset sign" (also called "Setting sun sign") is an ophthalmological sign seen in Hydrocephalus in infants and children
• Appearance: The eyes are deviated downward and inward, with the upper part of the iris and pupil covered by the lower eyelid, while sclera is visible above - resembling the sun setting below the horizon
• Cause: Raised intracranial pressure (ICP) from hydrocephalus compresses the midbrain tectal plate (dorsal midbrain), paralyzing upward gaze (Parinaud's syndrome)
• Associated features of raised ICP:
  • Bulging anterior fontanelle
  • Increasing head circumference (crossing centile lines)
  • Prominent scalp veins
  • "Cracked pot" sound on percussion (Mac Ewen sign)
  • Irritability, high-pitched cry, vomiting
• Significance: A critical sign indicating urgent need for investigation and treatment (ventriculoperitoneal shunt)

---

(c) Mac Ewen's Sign

• Definition: Also called "Cracked pot sign" or "Macewen's sign"
• What it is: A resonant, cracked-pot note heard on percussing the skull of an infant with Hydrocephalus or raised intracranial pressure
• How elicited: Gently percuss the skull with a finger; in hydrocephalus, the thinned skull bones over the distended ventricles produce a hollow, "cracked earthenware pot" sound
• Mechanism: Hydrocephalus causes thinning and separation of cranial sutures; the large air-fluid interface under the thin skull produces this characteristic sound
• Clinical significance: Indicates significantly raised ICP and widely separated cranial sutures; requires immediate neurosurgical evaluation
• Also seen in: Brain abscess (over the abscess cavity), cerebral tumor
• Named after: Sir William Macewen (Scottish neurosurgeon, 1848-1924)

---

(d) Leukemia

• Definition: Leukemia is a malignant (cancerous) proliferation of white blood cells (leukocytes) originating in the bone marrow, leading to uncontrolled production of abnormal, immature WBCs (blasts)

  • Neutropenia → Recurrent infections, fever
  • Bone pain (blasts infiltrate bone marrow)
  • Hepatosplenomegaly (liver and spleen enlargement)
  • Lymphadenopathy (swollen lymph nodes)
  • CNS involvement → Headache, vomiting (raised ICP)
  • Weight loss, anorexia, malaise
• Diagnosis:
  • CBC: Very high WBC (may be >100,000/μL) with blasts, low Hb, low platelets

• Treatment (ALL):
  • Induction (4 weeks): Vincristine + Prednisolone + Asparaginase (aim: complete remission)
  • Consolidation/CNS prophylaxis: Intrathecal methotrexate
  • Maintenance (2-3 years): 6-Mercaptopurine + Methotrexate
  • Bone marrow transplant (high-risk cases)
• Prognosis: ALL in children has 85-90% cure rate with modern chemotherapy

  • Watchful waiting (48-72 hours) for mild cases in children >2 years
  • Antibiotics: Amoxicillin (first line, 10 days); Amoxicillin-clavulanate if resistant
  • Analgesics: Paracetamol/Ibuprofen for pain and fever
  • Myringotomy + Grommet tubes (ventilation tubes): For recurrent AOM (≥3 episodes/6 months) or OME with hearing loss
• Complications: Hearing loss, mastoiditis, meningitis, brain abscess, facial nerve palsy, cholesteatoma
• Nursing Care:
  • Ear drop instillation technique (warm drops; pull ear lobe down and back in children <3 years; up and back in older children)
  • Educate parents on breastfeeding benefits, avoiding bottle propping
  • Teach antibiotic compliance (complete the full course)
  • Audiometry follow-up after treatment

Persistent Nausea and Vomiting in Gallbladder Inflammation (Cholecystitis)

---

1. OVERVIEW

---

2. PATHOPHYSIOLOGY — WHY NAUSEA AND VOMITING OCCUR

Gallstone obstructs cystic duct
            ↓
Increased intraluminal gallbladder pressure
            ↓
Distension of gallbladder wall
            ↓
Mucosal phospholipases hydrolyze lecithin → toxic lysolecithins
Prostaglandins released → mucosal and mural inflammation
Bile salts directly damage mucosal epithelium
            ↓
Chemical inflammation + bacterial infection (in >40% of cases)
            ↓
Visceral afferent nerve stimulation (via celiac plexus / vagus nerve)
            ↓
NAUSEA AND VOMITING CENTRE in brainstem (area postrema) triggered
            ↓
Persistent nausea, vomiting, anorexia

• Biliary stasis and buildup of bile → chemical irritation
• Fever and sepsis → direct stimulation of the emetic centre
• Pain itself triggers nausea via the autonomic nervous system
• In gallstone ileus (a complication): bowel obstruction causes severe nausea and vomiting from intestinal distension

---

3. CLINICAL FEATURES OF ACUTE CHOLECYSTITIS

---

4. WHY VOMITING IS PERSISTENT (Not Self-Limiting)

---

5. INVESTIGATIONS

• CBC: Leukocytosis (WBC >10,000/mm³); WBC >15,000 suggests gangrene/empyema
• LFTs: Mildly elevated bilirubin, ALP (if CBD involved)
• Serum amylase/lipase: Rule out pancreatitis
• Electrolytes, BUN, creatinine: Assess dehydration from vomiting
• Blood cultures: If sepsis suspected

• Ultrasound (RUQ) - First Line:
  • Gallstones (echogenic foci with acoustic shadowing)
  • Gallbladder wall thickening (>4 mm)
  • Pericholecystic fluid
  • Sonographic Murphy's sign (pain directly on transducer pressure over GB)
  • Sensitivity 85%, Specificity 95%
• CT Abdomen (if US equivocal or complications suspected): Pericholecystic fat stranding, wall thickening, complications
• HIDA Scan (Hepatobiliary Scintigraphy): Gold standard for diagnosis; non-filling of gallbladder confirms cystic duct obstruction; sensitivity 97%

---

6. MANAGEMENT

A. IMMEDIATE SUPPORTIVE MANAGEMENT (for Nausea/Vomiting + Dehydration)

• Keep patient NPO to rest the gastrointestinal tract
• Reduces gallbladder stimulation from CCK (cholecystokinin) secreted after eating
• Prepares patient for possible urgent surgery

• IV Normal Saline or Lactated Ringer's: 20 mL/kg bolus, then maintenance
• Corrects dehydration and electrolyte imbalances caused by persistent vomiting
• Prevents renal compromise from volume depletion
• Monitor urine output (target >0.5 mL/kg/hr)

• Insert NGT with low intermittent suction if vomiting is severe or if ileus develops
• Decompresses the stomach, reduces nausea and risk of aspiration

B. ANTIBIOTIC THERAPY (Targets Infectious Component)

• Indicated because bile cultures are positive in >40% of patients
• Reduces bacterial-driven inflammation that perpetuates nausea

C. DEFINITIVE TREATMENT — CHOLECYSTECTOMY

• Percutaneous Cholecystostomy (PC-tube): Ultrasound or CT-guided drain placed into gallbladder; decompresses the gallbladder; used when surgery is too high risk
• Endoscopic Transmural Gallbladder Drainage: Endoluminal stent placed from gallbladder to duodenum; increasingly used in very high-risk non-surgical patients

INVESTIGATION ANALYSIS

REPORT 1 — USG Whole Abdomen (Medilink Diagnostics, Zira)

Findings Summary:

USG IMPRESSION:

1. 🔴 ACALCULOUS CHOLECYSTITIS (cholecystitis WITHOUT gallstones)
2. 🟡 Left-sided simple renal cortical cyst (12.5 × 12.4 mm, upper pole)
3. 🟡 Multiple moving internal echoes in UB lumen (Urine R/M & clinical correlation advised)

---

REPORT 2 — Liver Function Test / LFT (Dhawan Diagnostic Lab, Zira, 22.07.2026)

---

INTERPRETATION — PUTTING IT ALL TOGETHER

🔴 MOST CRITICAL FINDING: MASSIVELY ELEVATED TRANSAMINASES

Note: ALT > AST in this case (1690 vs 2340 - actually AST > ALT here). When AST > ALT significantly, consider: alcoholic hepatitis, ischemic hepatitis. However, in a 17-year-old without alcohol history, acute viral hepatitis remains #1.

The Acalculous Cholecystitis Connection:

• Acute Viral Hepatitis A and E - gallbladder wall thickening (4.8 mm) and pericholecystic fluid are well-recognized complications of acute viral hepatitis - the liver inflammation directly involves the biliary system
• This explains the nausea, vomiting, RUQ pain, fever - they are caused by the HEPATITIS, not primary gallbladder disease

The Bilirubin Pattern:

• Indirect bilirubin (2.5) > Direct bilirubin (0.8) = predominantly UNCONJUGATED hyperbilirubinemia
• This suggests hemolytic component + hepatic dysfunction - consistent with acute viral hepatitis

---

URGENT RECOMMENDED NEXT STEPS

🚨 IMMEDIATE:

1. Hospitalization is strongly recommended - AST 2340 and ALT 1690 in a 17-year-old requires close monitoring
2. Strict bed rest and hepatoprotective diet (no fats, no alcohol, no hepatotoxic drugs)
3. Stop ALL potentially hepatotoxic medications (including paracetamol/Crocin - avoid completely)

🧪 ADDITIONAL BLOOD TESTS NEEDED:

💊 MANAGEMENT GUIDELINES:

---

⚠️ RED FLAG WARNING SIGNS - GO TO ER IMMEDIATELY IF:

• Confusion, drowsiness, altered behavior (hepatic encephalopathy)
• Yellow eyes/skin deepening rapidly (increasing jaundice)
• Bleeding from any site (gums, nose, urine, stool)
• Severe abdominal distension (ascites)
• Inability to eat or drink at all for >24 hours
• High fever with rigors

---

SUMMARY FOR THE FAMILY

Armaan (17 years) has Acute Hepatitis (liver inflammation) - most likely due to a viral infection (Hepatitis A is most probable at this age). The gallbladder findings (acalculous cholecystitis) are a complication of the liver infection - not a separate disease. The nausea and vomiting are caused by the liver condition. This is a serious but usually recoverable illness with proper rest, diet, hydration, and close monitoring. The most urgent test needed NOW is PT/INR (to check if the liver's clotting ability is intact) and Anti-HAV IgM to confirm the diagnosis. Please see a gastroenterologist or physician TODAY.

Rheumatic Fever in Children (Acute Rheumatic Fever - ARF)

---

1. DEFINITION

Key Point: Rheumatic fever follows throat (pharyngeal) infection ONLY - NOT skin infection by GAS. It appears 2-3 weeks after the streptococcal throat infection.

---

2. EPIDEMIOLOGY

---

3. ETIOLOGY AND PATHOGENESIS

Group A β-Hemolytic Streptococcus (GAS) pharyngitis
(Rheumatogenic strains: M protein types 1, 3, 5, 6, 18)
                    ↓
Vigorous humoral + cellular immune response
                    ↓
Streptococcal antibodies CROSS-REACT with:
• Myocardium → CARDITIS
• Synovial tissue → ARTHRITIS
• Basal ganglia (CNS) → CHOREA
• Skin/subcutaneous → Erythema marginatum, nodules
                    ↓
T-cell infiltration in valve endothelium (in carditis)
Activated monoclonal autoantibodies attack cardiac valves
                    ↓
PANCARDITIS (endocarditis + myocarditis + pericarditis)
                    ↓
Chronic valve scarring → RHEUMATIC HEART DISEASE

---

4. CLINICAL FEATURES

---

MAJOR MANIFESTATIONS (JONES Criteria - 2015 Revised)

1. 🦴 JOINT INVOLVEMENT (Arthritis) — Most common (75% of cases)

• Migratory polyarthritis - inflammation moves from one large joint to another
• Joints affected: knees, ankles, elbows, wrists (large joints)
• Each joint affected for 2-3 days then spontaneously improves and another joint flares
• Warm, red, swollen, extremely painful joints
• Pain out of proportion to clinical findings
• Dramatic response to Aspirin (within 24-48 hours) - almost pathognomonic
• Without treatment: self-limiting, resolves in ~4 weeks
• Does NOT cause permanent joint damage (unlike rheumatoid arthritis)

2. ❤️ CARDITIS — Most serious (50-80% of cases)

• Occurs in approximately 80% of patients
• Involves all layers: PANCARDITIS (endo + myo + pericarditis)
• Endocarditis → Valvular inflammation → murmurs
  • Mitral valve most commonly affected (nearly 100%)
  • Aortic valve in 20-30%
  • Mitral regurgitation: most common murmur (blowing, pansystolic, apex)
  • Carey-Coombs murmur: mid-diastolic (due to valvulitis)
• Myocarditis → Heart failure, cardiomegaly, tachycardia (out of proportion to fever)
• Pericarditis → Chest pain, friction rub
• Subclinical carditis: detected only on Doppler echocardiography (without clinical signs)
• Aschoff bodies: pathognomonic granulomatous lesion seen histologically in rheumatic carditis

3. 🧠 SYDENHAM'S CHOREA (St. Vitus Dance) — 10-15% of cases

• Involuntary, purposeless, irregular, jerky movements of limbs, face, trunk
• Milkmaid's grip: inability to sustain handgrip (grip alternately tightens and loosens)
• Jack-in-box tongue: tongue darts in and out involuntarily
• Emotional lability, irritability, behavioral changes (may precede motor symptoms)
• Occurs late in the course (weeks to months after streptococcal infection)
• Usually self-limiting: resolves within weeks to months
• May occur WITHOUT any other manifestations (isolated chorea = still ARF)

4. 🔴 ERYTHEMA MARGINATUM — <5% of cases (but pathognomonic)

• Distinctive, evanescent (comes and goes) rash
• Annular (ring-shaped) or serpiginous (snake-like) erythematous lesions with central clearing
• Appears on trunk, upper arms, legs - spares the face
• Blanches on pressure (non-fixed)
• Fluctuates over weeks; worsens with heat/fever
• Seen only in patients WITH carditis

5. ⬜ SUBCUTANEOUS NODULES — <5% of cases

• Firm, painless, mobile, round nodules 0.5-2 cm
• Located over bony prominences and tendons: elbows, knees, wrists, occiput, spine
• Associated with severe carditis
• Resolve spontaneously in weeks

---

MINOR MANIFESTATIONS

---

5. DIAGNOSIS — 2015 REVISED JONES CRITERIA (AHA)

Evidence of GAS Infection (MANDATORY - at least one):

• Positive throat culture for Group A Streptococcus
• Positive rapid antigen test (Rapid Strep Test)
• Elevated or rising ASO titre (Anti-Streptolysin O) - most commonly used
• Elevated Anti-DNase B antibodies
• Elevated Anti-hyaluronidase antibodies

Note: Absence of elevated ASO/antibody titer is strong evidence AGAINST rheumatic fever.

Diagnostic Rule:

7. TREATMENT

A. HOSPITALIZATION

• Bed rest (especially if carditis present)
• Monitoring and management
• Initiation of prophylaxis

Important: NSAIDs/Aspirin treat arthritis and fever but do NOT prevent cardiac damage or alter the course of carditis.

D. TREATMENT OF CARDITIS

E. TREATMENT OF SYDENHAM'S CHOREA

• Usually self-limiting - resolves in weeks to months without treatment
• Haloperidol or carbamazepine for severe/disabling chorea

---

4. CLINICAL FEATURES (ENLISTED)

A. Symptoms

1. Periorbital puffiness - early morning, first noticed by parents; most common presenting complaint in children
2. Pedal edema - bilateral pitting edema of feet and ankles
3. Abdominal distension - due to ascites
4. Frothy/foamy urine - due to heavy proteinuria (urine froths in toilet)
5. Decreased urine output (oliguria) - due to volume depletion
6. Anorexia, malaise, fatigue

• Age <1 year or >12 years (atypical age for MCD)
• Steroid resistance (no response in 8 weeks)
• Steroid dependence
• Macroscopic hematuria, persistent low complement
• Extrarenal features (rash, arthritis)
• Suspected secondary cause

---

6. COMPLICATIONS (ENLISTED)

A. Infections (Most Common Cause of Death in Children)

1. Spontaneous Bacterial Peritonitis (SBP) - 2-6% of cases; Streptococcus pneumoniae most common (because IgG and complement lost in urine → opsonic defect)
2. Cellulitis - protein-rich edema fluid is a growth medium for bacteria
3. Septicemia, Meningitis
4. Pneumococcal infections - children especially vulnerable
5. Gram-negative sepsis (E. coli, Klebsiella)

B. Thromboembolism (Most Serious Complication)

• Up to 20% of patients experience thrombotic events
• Renal vein thrombosis - flank pain, hematuria, acute deterioration of renal function; most common in membranous nephropathy
• Deep Vein Thrombosis (DVT)
• Pulmonary embolism
• Cerebral venous thrombosis
• Mechanism: Loss of antithrombotic proteins (Protein C, Protein S, Antithrombin III) in urine + elevated clotting factors (I, V, VIII, X) + hyperviscosity + platelet hyperaggregability

C. Metabolic Complications

1. Protein malnutrition - muscle wasting, growth retardation in children
2. Hypocalcemia - vitamin D-binding protein lost in urine → low 25-OH vitamin D → low Ca²⁺
3. Osteoporosis/Rickets - from vitamin D deficiency + steroid therapy
4. Iron deficiency anemia - transferrin lost in urine
5. Zinc deficiency - impaired wound healing, growth failure
6. Hypothyroidism - thyroid-binding globulin lost in urine
7. Drug toxicity - drugs bound to albumin have increased free fraction (increased toxicity)

D. Renal Complications

1. Acute Kidney Injury (AKI) - from volume depletion (underfill), sepsis, renal vein thrombosis, interstitial nephritis (from diuretics)
2. Chronic Kidney Disease (CKD) - especially in FSGS and MPGN
3. Progression to ESRD - particularly steroid-resistant forms

E. Cardiovascular

1. Hypertension - from fluid overload
2. Accelerated atherosclerosis - from chronic hyperlipidemia
3. Pericardial effusion - in anasarca

---

7. TREATMENT (ENLISTED)

A. General / Supportive Measures

1. Rest - during active edema phase
2. Diet:
   • Low sodium (1-2 g/day) - reduces edema
   • Normal to high protein (1.5-2 g/kg/day) - to replace urinary losses
   • Low fat - manage hyperlipidemia
   • Adequate calories for growth (in children)
3. Fluid restriction - only if severe hyponatremia

B. Treatment of Edema

C. Specific Treatment — CORTICOSTEROIDS (Primary NS)

• Remission: Urine protein negative/trace for 3 consecutive days
• Relapse: Urine protein 3+ for 3 consecutive days after remission
• Steroid Sensitive NS (SSNS): Remission within 8 weeks (90% of MCD)
• Steroid Resistant NS (SRNS): No remission after 8 weeks of full-dose steroids
• Frequent Relapsing NS (FRNS): ≥2 relapses in 6 months or ≥4 in 12 months
• Steroid Dependent NS (SDNS): Relapses during steroid taper or within 2 weeks of stopping

D. Steroid-Sparing Agents (for FRNS/SDNS/SRNS)

E. Treatment of Hyperlipidemia

• Statins (Atorvastatin, Rosuvastatin) for persistent hyperlipidemia or high cardiovascular risk
• Dietary fat restriction

F. Prevention / Treatment of Thrombosis

• Low molecular weight heparin (LMWH) - if albumin <2 g/dL and additional risk factors
• Warfarin - for established thrombosis (DVT, pulmonary embolism, renal vein thrombosis)
• Maintain adequate hydration

G. Prevention / Treatment of Infections

• Pneumococcal vaccine - strongly recommended in all children with NS
• Varicella vaccine - before steroid therapy if possible
• Penicillin prophylaxis - during active nephrotic state in some centers
• Prompt antibiotic treatment for infections (cefotaxime for peritonitis)

H. Treatment of Specific Causes

• Membranous (secondary): ACE inhibitor/ARB + immunosuppression
• Lupus nephritis: Hydroxychloroquine + steroids + MMF or cyclophosphamide
• Diabetic nephropathy: Tight glucose control + ACE inhibitor/ARB (renoprotective)
