A baby born at 28 weeks of gestation with a birth weight of 600 g was

A baby born at 28 weeks of gestation with a birth weight of 600 g was discharged at 42 weeks with a weight of 1.3 kg. He is on breast feeding and cup feeding with formula milk. At the 1-week review the mother complains that the baby is vomiting milk while burping. The current weight is 1.5 kg and the baby appears well. What is the most appropriate management step at this stage? A) Advice mother not to overfeed. B) USS abdomen C) Prescribe domperidone. D) Readmit for assessment. E) Train her the proper burping technique

The answer is confidently E) Train her the proper burping technique. Here is the full reasoning:

Answer: E - Train her the proper burping technique

Clinical Analysis

Key features of this case:

Feature	Significance
Preterm infant (28 weeks), now at 42 weeks corrected age	High risk for GOR due to immature lower oesophageal sphincter
Birth weight 600 g, now 1.5 kg	Excellent weight gain (+200 g in 1 week) - thriving
Vomiting during burping	Positional/mechanical, not pathological projectile vomiting
Baby appears well	No danger signs, no dehydration, no distress
Mixed breast + cup feeding with formula	Air swallowing during cup feeding is very common

Why E is correct

Vomiting/positing during burping in a well, thriving neonate is overwhelmingly due to improper burping technique or air swallowing, not pathological GOR or pyloric stenosis. The single most effective and safe first-line intervention is education on proper burping:

Hold upright over shoulder after feeds
Gentle back rubbing/patting
Smaller, more frequent feeds
Upright positioning for 20-30 min post-feed

This is a well baby with good weight gain - no investigation or drug treatment is needed at this stage.

Why the other options are wrong

A) Advise mother not to overfeed - Weight gain of 200 g/week is actually appropriate for a preterm infant (target ~15-20 g/kg/day). There is no evidence of overfeeding, and this advice would be incorrect and potentially harmful.

B) USS abdomen - This would be warranted if pyloric stenosis were suspected (projectile, non-bilious vomiting in a hungry, failing-to-thrive infant aged 2-8 weeks). This baby has good weight gain and vomiting only during burping, not forceful projectile vomiting.

C) Prescribe domperidone - Domperidone carries a black box warning for cardiac arrhythmia (QTc prolongation), especially in premature infants. It should NOT be first-line - and critically, this is a thriving baby with a positional/technique issue, not pathological GOR requiring pharmacotherapy.

D) Readmit for assessment - There is no clinical indication. The baby is well, gaining weight appropriately, and has no danger signs. Re-admission would be unnecessary and costly.

Teaching Point

In neonatology/paediatrics, the key differentiator is whether the baby is thriving or not:

Thriving + vomiting = reassurance + technique correction (GOR/posseting)
Failing to thrive + vomiting = investigate (pyloric stenosis, GORD, metabolic disease, etc.)

This baby gained 200 g in one week, which is reassuring. The correct management is simple parental education on burping technique - the most appropriate, safe, and effective step.

A 1-year-old boy was brought to the hospital by his mother with a left side undescended testes with the testes being palpable at the superficial inguinal ring. What is the most appropriate management at this point? A) Administer 1 dose of testosterone and review in 3 months. B) Refer to a paediatric surgeon. C) Perform an ultrasound of the abdomen. D) Karyotyping E) Reassure and send home

The textbook content is very clear. Here is the complete answer:

Answer: B - Refer to a Paediatric Surgeon

Clinical Analysis

Key features:

Feature	Significance
Age: 1 year	Past the window for spontaneous descent (expected by 3-6 months)
Left undescended testis	Unilateral - still requires orchidopexy
Palpable at superficial inguinal ring	Palpable UDT - simpler surgical approach (inguinal orchidopexy)

Why Referral is Needed Now

According to the Sabiston Textbook of Surgery:

"The undescended testis is associated with histologic and morphologic changes as early as 6 months of age, whereas atrophy of Leydig cells, a decrease in tubular diameter, and impaired spermatogenesis can occur by 2 years of age."

"For unilateral palpable testis in the inguinal canal, standard dartos pouch orchidopexy is performed at 6 to 12 months of age."

This child is already 1 year old - he is at the upper limit of the recommended surgical window. Every month of delay increases the risk of permanent damage to the germinal epithelium and future fertility. Prompt referral to a paediatric surgeon for orchidopexy is the correct action.

Management Algorithm for This Case

Undescended testis at 1 year
         |
    Is it palpable?
         |
        YES (at superficial inguinal ring)
         |
    Refer to paediatric surgeon
         |
    Inguinal/dartos pouch orchidopexy

Why the Other Options are Wrong

A) 1 dose of testosterone + review in 3 months - Hormonal therapy (hCG or GnRH analogues) has very low success rates (~20%) and is not recommended in current guidelines. At age 1, watchful waiting with hormonal therapy would further delay definitive treatment beyond the safe surgical window.

C) USS abdomen - Ultrasound is NOT indicated for a palpable undescended testis. It is only useful for localising a non-palpable (impalpable) testis to distinguish intraabdominal from absent testis. The testis here is clearly palpable at the superficial inguinal ring.

D) Karyotyping - Indicated for ambiguous genitalia or bilateral impalpable testes (to exclude conditions like anorchidism or disorders of sex development). A unilateral palpable UDT in an otherwise normal boy does not require karyotyping.

E) Reassure and send home - This is incorrect and potentially harmful. Spontaneous descent virtually never occurs after 6 months of age. Doing nothing at 1 year risks permanent infertility and an increased lifetime risk of testicular malignancy (4-10x higher in UDT, and orchidopexy before puberty reduces but does not eliminate this risk).

Summary of Long-Term Risks of Untreated Cryptorchidism

Risk	Details
Infertility	Germ cell loss accelerates after 6 months; bilateral UDT carries high infertility risk
Testicular malignancy	4-10x increased risk; seminoma most common
Torsion	Undescended testes are more prone to torsion
Psychological	Absent scrotal testis can affect self-image in older children

The correct and most appropriate management at this stage is to refer to a paediatric surgeon for orchidopexy - which should ideally be performed between 6-18 months of age. This child at 1 year is within that window, so prompt referral is essential.
