Question 1 · Medium
A 2-year-old girl had her cleft palate repaired at 11 months. Her mother now reports that she does not respond well to sounds, and examination shows dull, retracted tympanic membranes on both sides. Which mechanism best explains this?
1. ADamage to the cochlea during palate surgery
2. BRecurrent nasal regurgitation into the middle ear
3. CPoor tensor veli palatini action on the Eustachian tube
4. DAbsence of the stapedius reflex from facial palsy
Show answerHide answer
Answer: C · Poor tensor veli palatini action on the Eustachian tube
In cleft palate, the tensor veli palatini and levator veli palatini are abnormally inserted, so the tensor cannot open the Eustachian tube properly. The middle ear is poorly ventilated, causing otitis media with effusion and conductive hearing loss in most children with cleft palate, and this can persist after repair. Hearing assessment is part of routine cleft care, and grommets are inserted when hearing loss is significant. Unrecognised hearing loss adds to speech delay.
- A: Palate surgery does not touch the cochlea; this hearing loss is conductive.
- B: Nasal regurgitation affects feeding and speech, not middle ear ventilation directly.
- D: The stapedius reflex has nothing to do with middle ear effusion.
Question 2 · Hard
A newborn in the special newborn care unit has a small, receding lower jaw, a U-shaped cleft of the soft palate, and episodes of noisy breathing, chest retractions and desaturation, worse when lying on his back. What is the most appropriate first step to manage his airway?
1. AImmediate tracheostomy
2. BEarly palate repair in the first week
3. CMandibular distraction osteogenesis
4. DNurse the baby prone or on the side
Show answerHide answer
Answer: D · Nurse the baby prone or on the side
Micrognathia, glossoptosis (the tongue falling back) and a U-shaped cleft palate form the Pierre Robin sequence. The small jaw lets the tongue fall back and block the pharynx, especially when supine. The first step is prone or lateral positioning; if this fails, a nasopharyngeal airway is used, and only persistent obstruction needs mandibular distraction, tongue-lip adhesion or tracheostomy. The jaw often grows enough over the first year for the airway to improve, and the palate is repaired later in the usual way.
- A: Tracheostomy is a last resort after simpler measures fail.
- B: Palate repair does not relieve tongue-based airway obstruction.
- C: Distraction is reserved for obstruction that persists despite simpler measures.
Question 3 · Medium
A mother in rural Odisha brings her plump 7-month-old son to the CHC: since morning he has had intermittent spells of inconsolable crying with knees pulled to the chest, is limp and pale in between, has vomited twice and has just passed a jelly-like red stool. A firm curved mass lies under the right costal margin. Which investigation is preferred to confirm the diagnosis?
1. APlain X-ray of the abdomen
2. BUltrasound of the abdomen
3. CDiagnostic laparoscopy
4. DCT scan of the abdomen
Show answerHide answer
Answer: B · Ultrasound of the abdomen
Episodic colicky pain with pulling up of the legs, lethargy, vomiting, 'red currant jelly' stool and a sausage-shaped mass in an infant of 6 months to 2 years is intussusception, most often ileocolic. Ultrasound is the investigation of choice: it shows a target or doughnut sign in cross-section and a pseudokidney sign in long section, with high accuracy and no radiation. A plain film may be normal early. Confirmed cases without peritonitis go on to image-guided enema reduction.
- A: A plain film is often normal early and cannot confirm the diagnosis.
- C: Laparoscopy is invasive and not a first diagnostic step.
- D: CT adds radiation and is not needed in a typical infant.
Question 4 · Hard
A 50-year-old man had an excision biopsy of a changing mole on his thigh. Histology shows nodular melanoma with a Breslow thickness of 1.8 mm, without ulceration and with clear margins. There are no palpable groin nodes and staging scans are clear. What is the most appropriate next step?
1. AWide local excision with a 5 cm margin alone
2. BObservation, as the biopsy margins are clear
3. CWide local excision (1-2 cm margin) with sentinel node biopsy
4. DElective inguinal block dissection
Show answerHide answer
Answer: C · Wide local excision (1-2 cm margin) with sentinel node biopsy
An excision biopsy is diagnostic; definitive treatment is a wide local excision whose margin depends on Breslow thickness: about 1 cm for tumours up to 1 mm, 1-2 cm for 1-2 mm, and 2 cm for thicker tumours. For a melanoma of 1.8 mm with clinically negative nodes, sentinel lymph node biopsy is recommended at the time of wide excision, because it stages the regional nodes and guides adjuvant therapy. Old 5 cm margins gave no survival benefit. Elective node dissection without nodal disease has been replaced by sentinel biopsy.
- A: 5 cm margins add morbidity without improving survival and miss nodal staging.
- B: A clear excision biopsy margin is not an adequate oncological margin.
- D: Block dissection is for proven nodal disease, not clinically negative nodes.
Question 5 · Medium
A 9-year-old girl, born to parents who are first cousins, has had severe sunburn after brief sun exposure since infancy, with freckling and dry skin on her face. She now has two basal cell carcinomas and a squamous cell carcinoma on her face. Which mechanism underlies her condition?
1. ADefective homologous recombination
2. BDefective nucleotide excision repair
3. CDefective mismatch repair
4. DLoss of the p53 checkpoint at birth
Show answerHide answer
Answer: B · Defective nucleotide excision repair
Extreme sun sensitivity from infancy, freckling and multiple skin cancers in childhood, with parental consanguinity (autosomal recessive), is xeroderma pigmentosum. The defect is in nucleotide excision repair, which removes UV-induced pyrimidine (thymine) dimers; unrepaired dimers cause mutations and skin cancers, including melanoma, at a young age. Strict sun protection, regular skin surveillance and early excision of tumours are the mainstay. Eye and neurological problems can also occur.
- A: Homologous recombination defects (BRCA) cause breast and ovarian cancer.
- C: Mismatch repair defects cause Lynch syndrome (colon and endometrial cancer).
- D: Inherited p53 loss is Li-Fraumeni syndrome, with sarcomas and breast cancers.
