Causes of Neonatal Jaundice

---

Unconjugated (Indirect) Hyperbilirubinemia

1. Physiologic / Benign

2. Hemolysis

3. Infection

• Sepsis (bacterial)
• Urinary tract infection
• TORCH infections (Toxoplasmosis, Rubella, CMV, Herpes, Syphilis) - can cause both conjugated and unconjugated

4. Obstruction (increased enterohepatic circulation)

• Hirschsprung disease
• Meconium ileus
• Duodenal atresia
• Pyloric stenosis (presents >1 week)

5. Metabolic / Genetic

---

Conjugated (Direct) Hyperbilirubinemia

Biliary / Structural

• Biliary atresia - progressive jaundice with dark urine and acholic (pale) stools; age-sensitive - Kasai procedure must be done early
• Choledochal cyst
• Alagille syndrome (bile duct paucity)
• Bile duct strictures / inspissated bile syndrome
• Byler disease (progressive familial intrahepatic cholestasis)
• Congenital hepatic fibrosis

Infectious

• Neonatal hepatitis (idiopathic or viral)
• TORCH infections (CMV, rubella, toxoplasmosis, syphilis, HSV)
• Gram-negative sepsis / listeriosis / tuberculosis
• Hepatitis B, HIV, echovirus, coxsackievirus

Metabolic / Genetic (conjugated predominant)

Other

• Parenteral nutrition (TPN) - prolonged use causes cholestasis
• Drugs/toxins

---

Timing as a Diagnostic Clue

---

Key Complications

• Kernicterus: unconjugated bilirubin crosses the blood-brain barrier at levels >20-25 mg/dL, causing bilirubin-induced neurologic dysfunction (BIND). Chronic irreversible damage = kernicterus. Most common causes of severe hyperbilirubinemia are hemolytic disease of the fetus/newborn (HDFN) and sepsis.

5. Galactosemia
6. Total parenteral nutrition (TPN)
7. Choledochal cyst

---

Part B: Pathophysiology of Physiological Jaundice (~3 marks)

1. Increased bilirubin production:
   • Fetal RBCs (HbF) have a shorter lifespan (~70-90 days vs 120 days in adults)
   • Newborns have higher RBC mass (polycythemia) and higher hematocrit
   • Result: more RBC breakdown → more heme → more bilirubin
2. Decreased hepatic conjugation:
   • Liver is immature at birth
   • UDP-glucuronyl transferase activity is low (only 1% of adult levels)
   • Reduced uptake proteins (ligandin/Y protein) in hepatocytes
3. Increased enterohepatic circulation:
   • Gut flora not yet established
   • Intestinal beta-glucuronidase deconjugates bilirubin back to unconjugated form
   • Delayed passage of meconium increases reabsorption

---

Part C: Treatment Modalities of Neonatal Jaundice (~4 marks)

• Mechanism: Blue-green light (wavelength 460-490 nm) converts unconjugated bilirubin in skin to water-soluble photo-isomers (lumirubin) excreted in bile/urine without conjugation
• Types: Conventional (overhead fluorescent), Fiberoptic blanket, LED phototherapy
• Indications: Based on AAP nomogram - age in hours + bilirubin level + risk factors
• Precautions: Eye protection, adequate hydration, monitor temperature, skin care
• Side effects: Loose stools, skin rash ("bronze baby syndrome" in conjugated jaundice), dehydration

• Indication: When phototherapy fails, bilirubin approaching neurotoxic levels (>20-25 mg/dL), signs of BIND/kernicterus, hydrops fetalis
• Double volume exchange (160-180 mL/kg) replaces ~85-90% of sensitized RBCs
• Removes bilirubin, antibodies, and provides fresh albumin

• IVIG: Used in Rh/ABO hemolytic disease - reduces hemolysis by blocking Fc receptors
• Phenobarbitone: Induces glucuronyl transferase (used before delivery in at-risk pregnancies)
• Clofibrate: Induces bilirubin conjugation (limited use)
• Zinc supplements: May reduce enterohepatic circulation

• Antibiotics for sepsis
• Thyroxine for hypothyroidism
• Surgical correction for biliary atresia (Kasai portoenterostomy - must be done before 60 days)

• Adequate feeding (frequent breastfeeding 8-12 times/day)
• Hydration

Q1. Option 1 — Respiratory Distress in Newborn (10 Marks)

Part A: Causes of Respiratory Distress in Newborn (~3 marks)

1. Respiratory Distress Syndrome (RDS/HMD) - most common in preterm
2. Transient Tachypnea of the Newborn (TTN)
3. Meconium Aspiration Syndrome (MAS)
4. Pneumonia (congenital/early-onset)
5. Pneumothorax
6. Pleural effusion / chylothorax

---

Part B: RDS - Etiology, Pathophysiology, Management (~7 marks)

• Prematurity (<37 weeks, especially <32 weeks) - most important
• Maternal diabetes (hyperinsulinism inhibits surfactant production)
• Cesarean section without labor (reduced cortisol surge)
• Male sex, second twin
• Perinatal asphyxia
• Genetic deficiency of surfactant proteins (SP-B, SP-C)

1. Deficiency of surfactant (dipalmitoyl phosphatidylcholine) in type II pneumocytes
2. Without surfactant, alveolar surface tension increases → alveolar collapse at end-expiration (atelectasis)
3. Decreased lung compliance → increased work of breathing
4. Ventilation-perfusion mismatch → hypoxemia
5. Hypoxemia → pulmonary vasoconstriction → right-to-left shunting (ductus arteriosus, foramen ovale) → worsening hypoxemia (vicious cycle)
6. Capillary leak + fibrin exudate forms hyaline membranes lining alveolar ducts (hence: Hyaline Membrane Disease)

Clinical Features (~3 marks):

1. Persistent cough >2 weeks (dry or productive)
2. Fever - low-grade, prolonged (>2 weeks), evening rise
3. Weight loss or failure to thrive (common presenting feature in children)
4. Night sweats
5. Fatigue, lethargy, anorexia
6. Lymphadenopathy (cervical most common - "scrofula") - firm, non-tender, may be matted

• Primary complex = Ghon focus (lung parenchyma) + hilar lymphadenopathy
• Usually asymptomatic or mild
• Complications: lobar collapse (enlarged nodes compressing bronchus), pleural effusion

• Tubercular meningitis (TBM): Fever, headache, vomiting, altered consciousness, meningismus, cranial nerve palsies; most severe form; CSF: lymphocytosis, raised protein, low glucose
• Miliary TB: Disseminated hematogenous spread; classical "millet seed" pattern on CXR; choroid tubercles on fundoscopy
• Abdominal TB (mesenteric nodes, peritonitis)
• TB spine (Pott's disease): kyphosis, gibbus deformity
• TB bones/joints, TB pericarditis

Diagnostic Approach (~3 marks):

• 2 TU (tuberculin units) of PPD injected intradermally; read at 48-72 hours
• Positive: Induration ≥10 mm (≥5 mm in HIV/immunocompromised/contact with TB)
• Indicates infection; does NOT distinguish active from latent TB

• Primary complex, hilar lymphadenopathy, consolidation, miliary pattern, pleural effusion
• Calcification (healed primary complex)

• Gastric aspirate (early morning on 3 consecutive days) - standard method in children who cannot expectorate
• Induced sputum (with nebulized hypertonic saline)
• Bronchoalveolar lavage (BAL)
• AFB smear (Ziehl-Neelsen stain) and culture (Lowenstein-Jensen medium - 4-6 weeks)
• CBNAAT/GeneXpert MTB/RIF - Rapid molecular test; detects MTB and rifampicin resistance within 2 hours; preferred first test (WHO recommendation)

• QuantiFERON-TB Gold, T-SPOT TB
• More specific than Mantoux (not affected by BCG); used in BCG-vaccinated children

• CBC: lymphocytosis, elevated ESR
• CSF analysis (if TBM suspected)
• Biopsy of lymph node (histology: caseating granulomas, Langhans giant cells)
• USG abdomen (mesenteric nodes, ascites)
• HRCT chest

• Revised IAP Scoring System / WHO clinical scoring - uses symptoms, nutrition, X-ray, Mantoux, contact history to classify as probable/possible TB when bacteriological confirmation unavailable

---

• Free delivery (normal and cesarean), including drugs, diagnostics, blood transfusion
• Free transport (home → facility → home)
• Free diet during hospital stay (3 days for normal delivery, 7 days for C-section)
• Exemption from all user charges; no out-of-pocket expenses
• For sick newborns up to 30 days: free treatment, drugs, transport, diagnostics

---

1. Peaked/tall T waves (earliest sign; >6 mEq/L)
2. Prolonged PR interval and widening of QRS complex (>7 mEq/L)
3. Flattening/disappearance of P waves
4. Sine wave pattern (merging of QRS and T waves)
5. Ventricular fibrillation / asystole (>9 mEq/L)

---

• Underweight: <5th percentile
• Normal: 5th-84th percentile
• Overweight: 85th-94th percentile
• Obese: ≥95th percentile BMI is not accurate in children <2 years (use weight-for-length instead), and does not distinguish fat mass from muscle mass.
