Q

How does rhesus haemolytic disease occur

A

Mum = rhesus negative
Baby = rhesus positive

Sensitising event eg trauma/abruption (baby’s blood exposed to mothers)
Mother develops antibodies against the baby’s blood = haemolytic anaemia
Unconjugated bilirubin is produced

Q

How is rhesus haemolytic disease prevented

A

With anti-D immunoglobulin:
At 28 weeks
After sensitising events
One dose after birth if the mother is known to be rhesus negative

Q

Two main reasons for physiological jaundice

A

Increased bilirubin production as fetal haemoglobin has a lifespan of 70 days (compared to adult 120)

Decreased conjugated bilirubin due to liver immaturity (why premature babies have a higher incidence)

Q

Why can breast milk feeding difficulties or infection cause jaundice in neonates

96

98
Q

Duodenal atresia X ray finding

A

Double bubble sign

99
Q

volvulus sign on X ray

A

Coffee bean sign

100
Q

Why can small bowel obstruction occur in cystic fibrosis

A

Delayed passage of meconium due to it being thicker - some meconium gets stuck in the distal ileum

101
Q

What treatment can help meconium pass in CF

A

Therapeutic contrast enema (gastrografin)

102
Q

Hirschsprung’s disease pathogenesis

A

Congenital absence of ganglia (both myenteric and submucosal plexus) in a segment of the colon

NB: 75% rectosigmoid

103
Q

Clinical features of Hirschsprung’s disease

A

Functional LBO with failure to pass meconium within 24 – 48 hours

abdominal distention + late bilious vomiting

PR would reveal a contracted distal segment
followed by a rush of liquid stool and temporary relief of symptoms

104
Q

Diagnosis Ix Hirschsprung’s disease

A
105
Q

Undescended testes / cryptorchidism treatment

A

Most will spontaneously descend by 6 months - 1 year

Orchidopexy at 1 year if still undescended

106
Q

Indirect vs direct inguinal hernia

A

NB: ring occlusion test can differentiate between a direct and indirect hernia

107
Q

What are neonatal inguinal hernias due to

A

Patent processus vaginalis (failure to become the tunica vaginalis)

108
Q

Inguinal hernias clinical features

A

Indirect – bulge lateral to the pubic tubercle
more prominent on crying

Look for signs of incarceration e.g. tender
lump, irritable, vomiting

109
Q

6/2 rule in the surgical treatment of Inguinal hernias

A

< 6 weeks operate within 2 days
< 6 months operate within 2 weeks
< 6 years operate within 2 months

Any signs of incarceration = emergency surgery

110
Q

Hypospadias definition

A

Presence of the urethral meatus on the ventral aspect of the penile shaft

(Testosterone is needed for the meatus to move distally during development)

111
Q

Zero to finals

A
112
Q

Which deficiency should you investigate in hypospadias and undescended testes

A

Low testosterone

113
Q

Clinical features of hypospadias

A

Meatus on the ventral surface
Hooded foreskin
Spraying on urination

114
Q

Testicular torsion pathogenesis

A

Twisting of the spermatic cord cutting off blood supply to the testicle

115
Q

Aetiology of testicular torsion

A

Peaks at times of high testosterone – larger
testes = more chance of twisting

Peak times are in neonates and pubertal teenagers

Neonates with undescended testes are at
higher risk because there is less secure attachment within the scrotum

Bell clapper deformity

116
Q

Clinical presentation of testicular torsion

A

Testicle displaced higher, more horizontal
Acutely swollen, tender testicle
Vomiting due to pain
Absent cremasteric reflex
Negative Prehn’s sign

117
Q

Negative prehns sign interpretation

A

differentiates between torsion and epididymitis - lift the testicle – if pain is relieved this is suggestive of epididymitis - if pain is not relieved – torsion

118
Q

Surgical emergency chances of survival for testicular torsion

A

< 6 hours – 90% chance of testicular survival

24 hours – 10% chance of testicular survival

119
Q

Intussusception definition

A

Condition where one section of bowel telescopes into the other, usually the ileum into the caecum

Presents 3 months – 2 years

120
Q

Aetiology intussusception

A

Classically preceded by viral infection
Meckel’s diverticulum
CF
Lymphoma

121
Q

Clinical features of intussusception

A

Episodes of colicky abdominal pain,
legs draw up
May be fine but lethargic in between episodes
Signs of SBO
Sausage shaped mass in the abdomen
Late sign – red current jelly stool due
to bowel ischaemia

122
Q

Diagnosis/Ix intussusception

A

USS – target/donut sign
AXR – dilated proximal bowel loops

123
Q

Treatment intussusception

A

Rectal air insufflation
- 75% success rate
- only perform if there are no signs of peritonism

Surgical correction if air insufflation fails or signs of ischaemia

124
Q

Pyloric stenosis definition

A

Hypertrophy of the pylorus muscle leading to gastric outlet obstruction causing projectile vomiting

Incidence peaks at 2-8 weeks

4 x more common in boys

125
Q

Clinical features of pyloric stenosis

A

Projectile vomiting very shortly after feeds
Non bilious
Hungry after vomiting
Dehydration
Weight loss is a late sign

126
Q

129
Q
