Q.2 Case Based Scenario/Applied Short Notes (Any 2 out of 3)

Q.2 (1) Genetic Counselling - Preventive Measures to Reduce Risk of Genetic Disorder in Second Child

• Review medical records, death certificates, autopsy reports of first child
• Without a precise diagnosis, risk estimation is impossible
• Arrange chromosome analysis (karyotype) / molecular genetic testing of stored specimens if available

• Autosomal dominant (AD): 50% recurrence risk with each pregnancy
• Autosomal recessive (AR): 25% recurrence risk
• X-linked recessive: 50% of sons affected, 50% of daughters carriers
• Chromosomal (e.g., Down syndrome): depends on translocation vs non-disjunction (1-2% recurrence for trisomy vs up to 100% for Robertsonian translocation carriers)
• Multifactorial (e.g., neural tube defects, congenital heart disease): 2-10% recurrence

• Full physical examination of both parents
• Karyotyping of both parents (especially for chromosomal disorders)
• Carrier testing (e.g., carrier status for cystic fibrosis, sickle cell, thalassaemia, PKU by molecular/biochemical methods)
• Family pedigree construction (3-generation minimum)

• Folic acid supplementation (5 mg/day if prior NTD; 400 mcg otherwise) before conception and through first trimester
• Avoidance of teratogens (alcohol, valproate, thalidomide, radiation)
• Good glycaemic control in diabetic mothers before conception (HbA1c <6.5%)
• Carrier screening in both partners before pregnancy
• Preimplantation Genetic Diagnosis (PGD) - if couple opts for IVF; embryo tested before implantation - avoids transmission of serious monogenic disorders
• Consanguinity counselling - avoid in high-risk families

• 1st trimester: Combined screening (nuchal translucency + PAPP-A + free beta-hCG); Chorionic Villus Sampling (CVS) at 10-13 weeks for karyotype/molecular analysis; Non-Invasive Prenatal Testing (NIPT) from 10 weeks
• 2nd trimester: Amniocentesis at 15-18 weeks (karyotype, enzyme assays, DNA analysis); Anomaly scan at 18-20 weeks; Triple/Quadruple marker screen (AFP, hCG, uE3, inhibin-A)
• Fetal blood sampling (cordocentesis): for haematological disorders

• Non-directive counselling - inform without pressuring decision
• Respect autonomy; discuss all options including continuing pregnancy, termination, adoption
• Connect with support groups
• Encourage partner involvement; address grief from loss of first child

• Offer prenatal diagnosis in all future pregnancies
• Recurrence risk quantification based on translocation vs free trisomy

Q.2 (2) Management of Cleft Lip Discovered During Newborn Examination at PHC

• Cleft lip is one of the most common congenital anomalies (1 in 700-1000 births)
• It is correctable by surgery with excellent cosmetic and functional outcomes
• Emphasize that the child can lead a completely normal life after treatment

• Normal breastfeeding may be difficult; teach mother alternative methods
• Use of soft, squeezable bottle with enlarged or specially shaped nipple (Haberman feeder / cleft palate nipple)
• Position the baby upright at 45-60 degrees during feeding to prevent aspiration
• Feed slowly, allow frequent burping
• For isolated cleft lip without palate involvement, breastfeeding is often possible with proper latching technique
• Monitor weight gain closely

• Pre-surgical orthodontic device worn from early weeks to reduce cleft gap and improve anatomy before surgery

• Refer to a higher centre (tertiary/district hospital) with a cleft team (plastic surgeon, orthodontist, ENT, speech therapist, paediatrician, psychologist)
• Provide written referral letter with details

• Timing: "Rule of 10" - when baby is 10 weeks old, weighs 10 pounds (4.5 kg), and has haemoglobin >10 g/dL
• Technique: Millard rotation-advancement flap (most common) or Tennison-Randall triangular flap
• Cleft palate (if present) repaired later at 9-18 months (Veau-Wardill-Kilner technique)

• Speech therapy - to address articulation problems
• Hearing assessment - high risk of otitis media with effusion; ENT follow-up
• Orthodontic treatment in school years (alveolar bone grafting at 7-9 years for alveolar clefts)
• Rhinoplasty and secondary revisions may be needed in late adolescence
• Psychological support for child and family

• Ensure weight gain is adequate; monitor milestones
• Iron and vitamin D supplementation as per national schedule

• All vaccines as per national immunization schedule to proceed normally

• National Programme for Control of Blindness and Visual Impairment and Rashtriya Bal Swasthya Karyakram (RBSK) - free screening, referral and treatment of congenital conditions including cleft lip/palate
• SMILE TRAIN and SMILE FOUNDATION support free cleft surgeries in India

Q.2 (3) 10-Day-Old Infant with Jaundice, Lethargy, Poor Feeding

• 10-day-old infant, yellow discoloration of eyes x 3 days (persisting beyond day 7)
• Lethargic but arousable; breastfeeding poorly
• Weight: 2.8 kg (birth weight estimation - likely low-birth weight if weight is this at 10 days after post-natal weight loss and then regain)
• Jaundice extended to palms and soles (Kramer zone 5 - SEVERE jaundice)
• Vaccinations: OPV-0 and Hepatitis B birth dose only

1. Most Likely Diagnosis [1 mark]

1. Neonatal sepsis (most likely given lethargy + poor feeding + prolonged jaundice)
2. Haemolytic disease of the newborn (Rh/ABO incompatibility)
3. Breast milk jaundice (but baby feeds poorly - less likely)
4. G6PD deficiency
5. Neonatal hepatitis / congenital infections (TORCH)
6. Hypothyroidism (congenital)

2. Management Plan [4 marks]

• Assess ABC (Airway, Breathing, Circulation)
• Check temperature, blood glucose (hypoglycaemia common in sick neonate)
• Assess severity of jaundice by Kramer's zones (palms + soles = zone 5 = severe)
• Assess for signs of bilirubin encephalopathy: high-pitched cry, arching (opisthotonus), seizures, poor suck

• Serum Total and Direct Bilirubin (TSB) - URGENT
• Complete Blood Count (CBC) with differential, peripheral smear
• Blood culture and sensitivity (suspected sepsis)
• Reticulocyte count
• Blood group of mother and baby (ABO and Rh)
• Direct Coombs test (DAT)
• Serum glucose, electrolytes
• Thyroid function test (T4, TSH) if available
• Urine routine, C/S
• CRP / procalcitonin

• IMMEDIATE initiation of phototherapy if TSB above threshold per AAP/NNF guidelines (at birth weight ~2.8 kg at 10 days - threshold is TSB ~15-18 mg/dL for conventional phototherapy)
• Intensive phototherapy (irradiance >30 µW/cm²/nm, multiple lights or fibreoptic blanket) if TSB near exchange transfusion threshold
• Expose maximum skin surface; protect eyes with patches; turn baby frequently
• Continue breastfeeding/adequate feeding during phototherapy

• Start empirical antibiotics: Inj. Ampicillin + Inj. Gentamicin (IV or IM) after blood culture is drawn
• IV fluids for hydration if oral feeding inadequate

• If TSB rises to exchange transfusion threshold despite intensive phototherapy (typically >20-25 mg/dL depending on gestational age/weight/clinical features) - arrange URGENT transfer to SNCU/NICU
• Also indicated if signs of acute bilirubin encephalopathy

• Continue breast feeding every 2 hours; counsel mother on correct technique
• If baby too lethargic to feed: expressed breast milk via nasogastric (NG) tube
• Do NOT supplement with water or sugar water (increases enterohepatic circulation)
• Adequate hydration reduces bilirubin by enhancing excretion

• This baby needs URGENT referral to SNCU at the district hospital
• Call 102 ambulance; stabilize with IV/IM antibiotics, start phototherapy during transport if portable unit available
• JSSK covers free transport, free treatment

• TSB every 4-6 hours during intensive phototherapy
• Plot on Bhutani nomogram
• Watch for rebound hyperbilirubinemia after stopping phototherapy

3. Advice About Vaccination [1 mark]

• OPV-0 (birth dose) ✓
• Hepatitis B (birth dose) ✓

• The current illness (jaundice + possible sepsis) means vaccination should be temporarily deferred until the baby is clinically well and stable
• Once recovered, all pending vaccines should be administered as per schedule without significant gap penalties - missed vaccines to be given at next available opportunity (catch-up immunization)
• BCG (if not given at birth due to <2.5 kg or illness) should be given when weight reaches 2.5 kg and baby is well
• Register at Anganwadi or PHC for regular immunization tracking (Antenatal and Child Health Register / RCH portal)
• Inform mother about Intensified Mission Indradhanush (IMI) for catch-up immunization if any dose is missed
