38
Q

A
  • Symmetrical inflammatory arthritis
  • if systemic: salmon pink rash
39
Q

What is haemorrhage disease of the newborn?

A

Also known as “Vit K deficiency bleeding
- babies have relatively low vitamin K in first few days after birth
- they do not have enough Vitamin K stores and also gut sterility
- Vit K is produced by gut bacteria
- typically occurs in breast fed babies (as formula is fortified with Vitamin K) in the first few days of life
- Can present as bleeding from mucous membranes, from the umbilical stump or cause intracerebral haemorrhage
- NICE guidelines recommend all newborn babies have a prophylactic dose of Vitamin K

40
Q

What is the function of Vitamin K?

A

Vitamin K is a fat soluble vitamin synthesised by gut bacteria - it is required for the production of clotting factor II, VII, IX and X in the liver

41
Q

What is Reye’s syndrome?

A

A rare complication that can develop if children take aspirin during a viral illness - mitochondrial dysfunction
- acute non-inflammatory encephalopathy with fatty liver failure

42
Q

What is necrotising enterocolitis?

A
  • life threatening illness.
  • Intestinal inflammation –> bacterial invasion of the bowel wall –>bowel necrosis and perforation
  • Occurs in premature formula fed infants in the 2nd or 3rd week of life
43
Q

What are the key features of pyloric stenosis?

A
  • Presents around the fourth week of life
  • projectile, postprandial, NON-BILLOUS vomiting associated with a voracious appetite.
  • A right upper quadrant abdominal mass (palpable olive) may also be felt
  • Hypochloraemic hypokalaemia metabolic acidosis
44
Q

What are the important symptoms of duodenal atresia?

A
  • bilious vomiting in the first days of life, presents much earlier than pyloric stenosis.
  • AXR - double-bubble sign, two air-filled spaces representing the stomach and duodenum

Jaundice in the first 24 hours is ALWAYS pathological

47
Q

What are the causes of physiological jaundice in the neonate?

A
  1. Fetal Hb has a shorter life-span that adult Hb - so is broken down at a much quicker rate than the immature liver can cope with - this leads to bilirubin accumulation
  2. Breast milk jaundice - presents typically within first week of life.
