Q

Ix for gastro-oesophageal reflux

A

clinical diagnosis

  • 24-hour oesophageal pH monitoring to quantify the degree of acid reflux - pH should be ABOVE 4
  • 24-hour impedance monitoring which is available in some centres. Weakly acidic or nonacid reflux, which may cause disease, is also measured
  • endoscopy with oesophageal biopsies to identify oesophagitis and exclude other causes of vomiting.

Q

Mx of gastro oesophageal reflux

A

uncomplicated - parental reassurance, adding inert thickening agents to feeds (e.g. Carobel), and smaller, more frequent feeds.

trial of alginate therapy ie Gaviscon not the same time as thickening agents

  • unexplained feeding difficulties (for example, refusing feeds, gagging or choking)
  • distressed behaviour
  • faltering growth - acid suppression with proton-pump inhibitors (e.g. omeprazole)

reduce the volume of gastric contents and treat acid-related oesophagitis

domeperidone - enhance gastric emptying - SEs arryhtmias

ABOVE FAILS
- cows milk protein allergy ???

surgical Mx only for children with complications unresponsive to intensive medical treatment or oesophageal stricture - Nissen fundoplication - fundus of the stomach is wrapped around the intra-abdominal oesophagus, is performed either as an abdominal or as a laparoscopic procedure.

  • High caecum at the midline
  • Feature in exomphalos, congenital diaphragmatic hernia, intrinsic duodenal atresia
  • May be complicated by the development of volvulus, an infant with volvulus may have bile stained vomiting
  • Diagnosis is made by upper GI contrast study and USS
  • Treatment is by laparotomy, if volvulus is present (or at high risk of occurring then a Ladd’s procedure is performed
    Obstruction with bilious vomiting is the usual presentation in the first few days of life but can be seen at a later age

any child with dark green vomiting needs an urgent upper GI contrast study to assess intestinal rotation unless signs of vascular compromise are present, when an urgent laparotomy is needed.

A
  1. rotavirus infection under 2 esp during winter
  2. others
    bacterial suggested by the presence of blood in the stools
    campylobacter jejuni

Shigella and some salmonellae produce a dysenteric type of infection, with blood and pus in the stool, pain and tenesmus

Cholera and enterotoxigenic Escherichia coli infection are associated with profuse, rapidly dehydrating diarrhoea.

  1. protozoan - Giardia and Cryptosporidium .
severe abdo pain

30
Q

which children will be at an increased risk of rehydration

A
  • infants, particularly those under 6 months of age or those born with low birthweight
  • if they have passed six or more diarrhoeal stools in the previous 24 hours
  • if they have vomited three or more times in the previous 24 hours
  • if they have been unable to tolerate (or not been offered) extra fluids
  • if they have malnutrition.
31
Q

assessment of gastroenteritis

A

most accurate measure of dehydration is the degree of weight loss during the diarrhoeal illness

  • no clinically detectable dehydration (usually <5% loss of body weight)
  • clinical dehydration (usually 5% to 10% loss of body weight)
  • shock (usually >10% loss of body weight; Fig. 14.9 and Table 14.1 ). Shock must be identified without delay.
32
Q

red flag signs of shock

A

general appearance -> appears unwell or deteriorating

Altered responsiveness, e.g. irritable, lethargic

sunken eyes
tachycardia
tachypnoea
reduced skin turgor

33
Q

what is isonatraemic and hyponatraemic dehydration

A

plasma sodium remains within normal range

loss of sodium more than water -> hyponatraemic

shift of water from extracellular to intracellular components

increase in brain volume -> seizures

extracellular depletion -> shock

34
Q

what is hypernatraemic dehydration

A

plasma concetration increases

causes high fever or hot, dry environment) or from profuse, low-sodium diarrhoea.

ECF becomes hypertonic therefore water comes out of the

Signs

  • jittery movements
  • increased muscle tone
  • hyperreflexia
  • convulsions
  • drowsiness or coma.
35
Q

when is stool culture required for gastroenteritis

A
  • septic
  • if there is blood or mucus in the stools,
  • immunocompromised
  • recent foreign travel
  • if the diarrhoea has not improved by day 7]- if the diagnosis is uncertain
36
Q

Mx if clinical dehydration in gastroenteritis
ORS mechanism

shock

safety net

A
  • oral rehydration solution
  • 50ml/kg over 4 hours as well as maintenance fluid
    adjunct to normal fluids or breastfeeding
  • deterioration or persisitent vomitting
  • continue breastfeeding

ORS contains sodium and glucose which allows cotransport of SGLT 1 to work. increases salt and water uptake in the small intestinal lumen Na moving into lumen also pulls water too.

no skl for 48 hours

Shock

  • Bolus therapy 20ml/kg
  • fluid deficit -> 100ml/kg/24hr

maintenacne fluids

  • first 10kg -> 100ml/kg
  • second 10kg -> 50ml/kg
  • subsequent kg ->20ml/kg

safety net
 Wash your hands (and your child’s) with soap and water after going to the toilet, changing nappies and before eating
 Regularly clean the toilet at home with disinfectant/bleach
 Do not share towels, flannels etc with your child
 Wash soiled clothes separately- soiled clothing and bedding should be washed at high
temperatures (60°)
 Keep children off school, playgroup etc until at least 48 hours after their last symptom
 Your child should not use swimming pools for another two weeks after they are well.

37
Q

Mx of hypernatraemic dehydration

A

you cant reduce sodium too quickly as it will lead to a shift of water into cerebral cells -> seizures and cerebral oedema

aim to reduce at less than 0.5 mmol/l per hour.

38
Q

DD for diarrhoea

A
Infection (gastroenteritis)
Inflammatory bowel disease
Lactose intolerance
Coeliac disease
Cystic fibrosis
Toddler’s diarrhoea
Irritable bowel syndrome
Medications (e.g. antibiotics)
39
Q

postgastroenteritis syndrome

A

Infrequently, following an episode of gastroenteritis, the introduction of a normal diet results in a return of watery diarrhoea. In such cases, oral rehydration therapy should be restarted.

40
Q

post gastroenteritis complications

A

Lactose intolerance
Irritable bowel syndrome
Reactive arthritis
Guillain–Barré syndrome

41
Q

what is coeliac disease

A

exposure to gluten causes an immune reaction that creates inflammation in the small intestine. It usually develops in early childhood but can start at any age.

In coeliac disease autoantibodies are created in response to exposure to gluten. These autoantibodies target the epithelial cells of the intestine and lead to inflammation. There are two antibodies to remember: anti-tissue transglutaminase (anti-TTG) and anti-endomysial (anti-EMA). These antibodies correlate with disease activity and will rise with more active disease and may disappear with effective treatment.

Inflammation affects the small bowel, particularly the jejunum. It causes atrophy of the intestinal villi. The intestinal cells have villi on them that help with absorbing nutrients from the food passing through the intestine. The inflammation causes malabsorption of nutrients and disease related symptoms.

42
Q

presentation of coeliac disease

A

faltering growth, abdominal distension and buttock wasting, abnormal stools, and general irritability
Diarrhoea
Fatigue
Weight loss
Mouth ulcers
Anaemia secondary to iron, B12 or folate deficiency
Dermatitis herpetiformis is an itchy blistering skin rash that typically appears on the abdomen

peripjeral neuropathy
cerebellar ataxia
epilepsy

HLA-DQ2

43
Q

diagnosis of coeliac

A

increased intraepithelial lymphocytes

  • villous atrophy
  • crypt hypertrophy

endoscopically followed by the resolution of symptoms and catch-up growth upon gluten withdrawal.

Check total immunoglobulin A levels to exclude IgA deficiency before checking for coeliac disease specific antibodies:

Raised anti-TTG antibodies (first choice)
Raised anti-endomysial antibodies

ass w
type 1 diabetes mellitus, autoimmune thyroid disease, Down syndrome, primary scleorising cholangitis, primary biliary cirrhosis
turner

44
Q

causes of chronic diarrhoea

A
  • In an infant with faltering growth, consider coeliac disease and cow’s milk protein allergy.
  • Following bowel resection, cholestatic liver disease or exocrine pancreatic dysfunction, consider malabsorption.
  • In an otherwise well toddler with undigested vegetables in the stool, consider chronic non-specific diarrhoea.

46
Q

diagnosis of crohn’s

A

endoscopic and histological findings on biopsy. Upper gastrointestinal endo­scopy, ileocolonoscopy and small bowel imaging are required. The histological hallmark is the presence of non-caseating epithelioid cell granulomata

Small bowel imaging may reveal narrowing, fissuring, mucosal irregularities and bowel wall thickening.
