Q

What is GERD?

What is possetting?

A

Gastro-oesophageal reflux (GOR) is the non-forceful regurgitation of milk and other gastric contents into the oesophagus

A small regurgitation of milk after breast feeding (this is quite normal)

Q

What are the symptoms of GERD?

A
  1. Recurrent regurgitation or vomiting.
  2. Witnessed episode of choking or apparent life-threatening event can sometimes occur.
  3. Respiratory problems (eg, cough, apnoea, recurrent wheeze and, less commonly, aspiration pneumonia).
  4. Typically develops before 8 weeks

Q

What are the red flags which don’t suggest GERD?

A
  1. Frequent, forceful (projectile) vomiting - may suggest hypertrophic pyloric stenosis in infants up to 2 months old.
  2. Bile-stained (green or yellow-green) vomit may suggest intestinal obstruction
  3. Haematemesis may suggest a bleed from the oesophagus, stomach or upper gut

Q

What are the investigations for GERD?

A

Not usually performed in mild cases In severe cases

FBC.

24-hour ambulatory oesophageal pH study
Usually will show frequent dips in pH <4.

Barium meal
To exclude underlying anatomical abnormalities in the oesophagus, stomach and duodenum that may cause symptoms similar to GORD

Endoscopy
Where oesophagitis is suspected.

Manometry
To assess oesophageal motility and lower oesophageal sphincter function.

Q

What is the treatment for GERD?

A
  1. Advise regarding position during feeds - 30 degree head-up
  2. Infants should sleep on their backs as per standard guidance to reduce the risk of cot death
  3. Ensure infant is not being overfed (as per their weight) and consider a trial of smaller and more frequent feeds
  4. A trial of thickened formula (for example, containing rice starch, cornstarch, locust bean gum or carob bean gum)
  5. A trial of alginate therapy e.g. Gaviscon. Alginates should not be used at the same time as thickening agents
  6. Trial of a PPI

Q

What is the treatment for poor feeding?

A

Poor feeding that is caused by an infection will normally stop when the infection is treated.

Treatment is the same for other causes of poor feeding.

This can involve changing the feeding schedule to consist of smaller, more frequent meals.

It can also involve switching feeding methods from breast to bottle

How is poor feeding different to poor growth?

Q

What are the different types of hernias?

A

Umbilical hernias form when the opening for the umbilical cord does not closely properly, which allows the abdominal lining and bowel to bulge out to form a lump.

Epigastric hernias form when tissues joining the muscles in the upper part of the abdomen have not formed properly and allow fatty tissue to bulge out to form a lump.

Q

What is the difference between ulcerative colitis and crohn’s?

A

Ulcerative colitis is limited to the colon while Crohn’s disease can occur anywhere between the mouth and the anus

In Crohn’s disease, there are healthy parts of the intestine mixed in between inflamed areas. Ulcerative colitis, on the other hand, is continuous inflammation of the colon

Ulcerative colitis only affects the inner most lining of the colon while Crohn’s disease can occur in all the layers of the bowel walls

Q

How is ulcerative colits diagnosed?

A

Endoscopy

  1. Colonoscopy + biopsy is generally done for diagnosis
    • However in patients with severe colitis colonoscopy should be avoided due to the risk of perforation - a flexible sigmoidoscopy is preferred
  2. Typical findings:
    • Red, raw mucosa, bleeds easily
    • No inflammation beyond submucosa (unless fulminant disease)
    • Widespread ulceration with preservation of adjacent mucosa which has the appearance of polyps (‘pseudopolyps’)
    • Inflammatory cell infiltrate in lamina propria
    • Neutrophils migrate through the walls of glands to form Crypt abscesses
    • Depletion of goblet cells and mucin from gland epithelium
    • Granulomas are infrequent

Barium enema

  1. Loss of haustrations
  2. Superficial ulceration, ‘pseudopolyps’
  3. Long standing disease: colon is narrow and short -‘drainpipe colon’

Q

How is crohn’s diagnosed?

A
  1. Bloods
    • C-reactive protein correlates well with disease activity
  2. Endoscopy
    • Colonoscopy is the investigation of choice
    • Features suggest of Crohn’s include deep ulcers, skip lesions
  3. Histology
    • Inflammation in all layers from mucosa to serosa
    • Goblet cells
    • Granulomas
  4. Small bowel enema
    • High sensitivity and specificity for examination of the terminal ileum
    • Strictures: ‘Kantor’s string sign’
    • Proximal bowel dilation
    • ‘Rose thorn’ ulcers
    • Fistulae
