Q

What is encopresis?

A

Significant prolonged jaundice due to high conjugated bilirubin levels. Suspect if lasts >14 days in term babies/>21 days in premature babies. Steatorrhoea - pale stool or yellow stool. Jaundice can be normal in neonate but biliary atresia is serious so needs to be excluded by measuring conjugated bilirubin level.
43
What is the management of biliary atresia? What happens if you don't treat?
Kasai portoenterostomy = attach section of the small intestine to the opening of the liver where the bile duct normally attaches, not always successful. Often pt need full liver transplant for full recognition. Untreated = cirrhosis w/i 6 months and liver failure w/i 1 year.

50
What is Hirschsprung's disease?
Congenital condition where parasympathetic ganglion cells of the myenteric/Auerbach's plexus are absent in the distal bowel and rectum. Normally responsible for stim peristalsis of large bowel, no stim = food can't pass. Aganglionic section = constricted = bowel obstruction, proximally the bowel is distended and full.

57
What are the ix into intussuscpetion and how is it managed?

Obstruction vs ileus
Obstruction - mechanical cause blocking the bowel Ileus - bowel doesn't work properly but no structural cause
63
What is volvulus? What are the CF?
Volvulus = twisting of a loop of bowel around its mesentary = closed loop bowel obstruction CF - bowel obstruction signs, over a few hours, lots of abdo distension, tympanic percussion, peritonism, sepsis if perforated. Most commonly in the caecum.

66
What is necrotising enterocolitis?
One of the most common neonatal surgical emergencies. Is variable injury to the bowel = mucosal damage to necrosis and perforation, thought to be an innate immune response to the microbiota of a premature infants gut = inflam and injury.

79
What is the management of appendicitis?
Lap appendicectomy
80
What is cryptochidism?
Undescended tests - testes haven't descended from the abdo, can be palpated in inguinal canal. The longer it takes for testes to descend, the less likely they will. Undescended tests = risk of testicular torsion, infertility and cancer
81
What is the management of cryptochidism?
- Watch and wait, most of the time will descend in 3-6 months - Orchidopexy if not descended in 6 months, done between 6 and 12m
82
What are retractile testes?
Before puberty it is normal that the testes move out of the scrotum into the inguinal canal when it is cold or cremasteric reflex is activated = retractile testicles and is normal.
83
What is the presentation of testicular torsion?
- Sudden onset severe pain in one testicle, often following minor trauma - High riding teste in scrotum - Unilat loss of cremasteric reflex - -ve Prehn's sign - Prepubertal or just after birth are the ages where you get it
84
What is the management of testicular torsion?
If not treated immediately = death or damage to tissue of testicle due to ischaemia, need to remove necrotic testicle if this is the case. Otherwise surgical exploration and fixation of the testicles w orchidoplexy - have about 6 hours to save the testis.
85
What is a consequence of neonatal jaundice?
Kernicterus - bilirubin can cross the blood brain barrier causing permanent brain damage
86

87
How do you manage physiological jaundice?
- Establish feeds - Phototherapy - blue spectrum light
88
What is Rigler's sign?
Sign of pneumoperitoneum on AXR, can see the bowel wall on either side.
89
How do you ix an undescended teste?
Examination under anaesthetic and diagnostic laparoscopy. Could do USS groin and abdo but testes in an infant are tiny! Might not be able to see
90
Why do you need to bring the testis down into the scrotum in undescended testes?
- Prevent testicular atrophy - Psychologcial benefit - Reduce risk of trauma - Reduce risk of testicular cancer and can self examine - Optimal temp for sperm production - too hot inside body
91
How do you manage hydroceoele?
Watch and wait - normally resolves by about 2.5 years, if hasn't then you manage
92
What is torted hydatid of morgagni?
Pathognonomic - blue spot sign. Has twisted on its blood supply. Just need analgesia and the bruise will go down on its own. Hydatid of Morgagni - Mullerian remnant, has no function but can cause pain
93
What is bell clapper deformity?
94
How do you manage umbilical hernia?
Only operate if hernia still present by the time child starts school - is likely to close on its own. There is a low risk of strangulation or problems, is a cosmetic problem.
95
Why is volvulus in a neonate so serious?
Most likely to affect the midgut - if it becomes ischaemic this will cause death of the bowel that is involved in absorption of nutrients - baby can't life without it, if necrotic bowel in this section can only palliate the baby.
96
What are the CF of viral hepatitis?
N+V, abdo pain, lethargy, jaundice - up to 50% don't develop Hepatomegaly, tender +/- splenomegaly Raised LFTs but normal coag normlly
97
Hep A vs Hep B vs Hep C
Hep A - faecal oral transmission, can be asymptomatic but most children mild illness and recover w/i 2-4w, no chronic liver disease Hep B - perinatal transmission, infected blood via healthcare procedures, sexually. 90% of infants who get hep b perinatally = chronic carriers, older children = 5-10% carriers, 1-2% fail Hep C - vertical transmission but can be cured
98
Chronic hep b
30-50% of asymptomatic carrier children develop chronic disease, 10% = cirrhosis w risk hepatocellular carcinoma. Treatment not v good
99
What is acute liver failure?
Hepatic necrosis w loss of liver func +/- hepatic encephalopathy, uncommon but high mortality - normally caused by infection or met condition
100

102
What is the management of acute liver failure?
Maintain BM >4mmol/L Broad spectrum abx and antifungals to prevent sepsis Prevent haemorrhage - IV vit K Prevent cerebral oedema by fluid restriction and mannitol if oedema develops Ultimately = liver transplant
103
