Q

What investigations would you do for coealiacs?

A

Serology:
* tissue transglutaminase (TTG) antibodies (IgA) are first-choice according to NICE
* endomyseal antibody (IgA)
needed to look for selective IgA deficiency, which would give a false negative coeliac result
* anti-casein antibodies are also found in some patients

Endoscopic intestinal biopsy- duodenum, usually in children you use jejunal biopsy showing subtotal villous atrophy
May see the following:
* Crypt hyperplasia
* Increase in intraepithelial lymphocytes
* Lamina propria infiltration with lymphocytes

* anti-gliadin antibody (IgA or IgG) tests are not recommended by NICE

Q

Management of Coeliacs?

A
  • Gluten- free diet
  • Patients with coeliac disease often have a degree of functional hyposplenism-all patients with coeliac disease are offered the pneumococcal vaccine
  • Coeliac UK recommends that everyone with coeliac disease is vaccinated against pneumococcal infection and has a booster every 5 years
  • Currrent guidelines suggest giving the influenza vaccine on an individual basis.

Q

What contains gluten?

A
  • wheat: bread, pasta, pastry
  • barley: beer
  • whisky is made using malted barley. Proteins such as gluten are however removed during the distillation process making it safe to drink for patients with coeliac disease
  • rye
  • oats- although GF, some react to them, also usually made in factory that is not GF so cannot have

rice
potatoes
corn (maize)
are GLUTEN FREE

Q

Managment of constipation if there is faecal impaction?

A
  • polyethylene glycol 3350 + electrolytes (Movicol Paediatric Plain) using an escalating dose regimen as the first-line treatment
  • add a stimulant laxative if Movicol Paediatric Plain does not lead to disimpaction after 2 weeks
  • substitute a stimulant laxative singly or in combination with an osmotic laxative such as lactulose if Movicol Paediatric Plain is not tolerated
  • inform families that disimpaction treatment can initially increase symptoms of soiling and abdominal pain

26
Management of constipation of infants who are or have been weaned?
* offer extra water, diluted fruit juice and fruits * if not effective consider adding lactulose
27
What shoudl you ask in Hx when child comes in with constipation?

32
Management of GORD in infants? | 2015 NICE
* advise regarding position during feeds - 30 degree head-up * infants should sleep on their backs * ensure infant is not being overfed (as per their weight) and consider a trial of smaller and more frequent feeds * a trial of thickened formula (for example, containing rice starch, cornstarch, locust bean gum or carob bean gum) * a trial of alginate therapy e.g. Gaviscon. Alginates should not be used at the same time as thickening agents * NICE do not recommend a proton pump inhibitor (PPI) to treat overt regurgitation in infants and children occurring as an isolated symptom. A trial of one of these agents should be considered if 1 or more of the following apply: * unexplained feeding difficulties (for example, refusing feeds, gagging or choking) * distressed behaviour * faltering growth If severe complications and medical treatment does not work: consider fundoplication | prokinetic agents e.g. metoclopramide should only be used with specialis
33
Complications of GORD in infants?
* Distress * Failure to thrive * Aspirtion * frequent otitis media * In older children: erosion may occur
34

39
Examination to assess for hydration?
* Cap refill * Skin tugor * Mucus membranes * Fontanelles * Urine output
40
How do you diagnose Gastroenteritis?
Clinical: suspect if sudden change in stool consitency to loose/ watery and/or sudden onset of vomiting Stool microbiology if: * septicaemia is suspected * Blood and/or mucus in stools * Child is immunocompromised * Recent travel abroad * Diarrhoea has not improved after 7 days * Diagnosis of GE uncertain And then treat accordingly * Assess dehydration and shock | DL tut
41
What clinical features would lead to you consider other diagnoses other than GE in a pt with diarrhoea and/or vomitting?
* Fever > 38 if less than 3 mnths; > 39 if older * Dyspnoea/tachypnoea * Altered LOC, bulging fontanelle, non-blanching rash * Bilious vomiting; blood/ mucus in stool * Severe/localised pain, rebound tenderness, abdo distension
42
How to assess for dehydration and shock? | What to ask about, look out for, red flags and hypernatraemia
Consider RF Ask about: * Appear unwell * altered responsiveness (irritable or lethargic) * Decreased urine output * Pale, mottled skin, cold extremities Look for: * Altered responsiveness * Skin colour changes, extremity temperature * Mucous membranes * Sunken eyes * Tissue turgor * Tachypnoea, tachycardia, cap refill, BP Red flags: * Altered level of consciousness * Tachycardia * Tachypnoea * Sunked eyes, reduced tissue turgor Consider hypernatraemia if: * Jittery * Increased muscle tone * Hyperreflexic * Convulsions * Drowsiness * Coma
43
Management of GE?
Fluid management GE without dehydration: * continue breast feeding and other milk feeds * Encourage fluid intake * Discourage fruit juices/ fizzy drinks * Offer ORS as a supplement if at risk of dehydration GE WITH dehyrdation incl hypernatraemia: * Use low osmolality ORS for oral rehydration * GIve 50ml/kg for fluid deficit over 4 hours as well as maintenance fluid * GIve ORS frequently and in small amounts * Consider supplementation with usual feeds if ORS refused (if no red flags) * Monitor response to ORS with regular clinical assessment Use IV fluids if: * Shock suspected or confirmed * Child with red flag symptoms/ signs despite ORS * Persistent vomiting of ORS
44
What are the points to remember if using IV for rehydration in GE?
* Use isotonic solution (0.9% NaCl +/- 5% glucose) for rehydration and maintenance * For those with suspected/ confirmed shock- give 100ml/kg bolus * For those without shock- add 50ml/kg for fluid deficit (or the deficit is weight in kg x % dehydration) * Measure U&Es and glucose regularly * Consider IV potassium supplementation when plasma potassium is known * If hypernatraemic dehyration- give over 48 hours to avoid cerebral odema
45
The child with GEhas now been rehydrated. How would you manage their nutrition?
* Give full strength milk straight away * Reintroduce child's usual solid foods * Avoid fruit juices/carbonated drinks until diarrhoea has settled
46
What advice would you give to a parent of a child who has GE? (hygiene, school return)

64
Investigations in acute liver failure?
Bloods: LFTs: Increased bilirubin (although may be normal in the early stages),increased ALT, AST,ALP, Coag- deranged clotting, increased plasma ammonia and decreased glucose ABG: frquently associated with acid/base imbalance Viral serology: detect hepatitis Imaging: CT/MRI brain: may show cerebral oedema in encephalopathy EEG: may show acute hepatic encephalopathy
65
Managment of acute liver failure?
Treatment of complications: Hypoglycaemia: Dextrose infusion Sepsis: broad spec abx Coagulation defect: FFP and PPI to prevent gastric bleeding. Vit K not usually indicated- if needed then usually indication for liver transplantation Cerebral oedema: fluid restriction and diuresis with mannitol Liver transplant: prothrombin time is the best marker of liver failure
66
Complications of acute liver failure?

* B * C
69
How is Hep A spread?
* Faeco-oral route
70
Epidemiology of Hep B?
* Most common cause of hepatitis globally * High prevalence regions include sub-Saharan Africa, Asia and the Pacific Islands. * Decline of disease in children and adolescents in the UK is due to routine vaccination * Incubation period usually 60-90 days.
71
Features of Hep B Infection?
* Only 5% of children have jaundice and severe symptoms, but the majority cannot clear the infection and develop chronic disease. * 30-50% of adults experience jaundice, fever, malaise, and darkening of urine and lightening of stool. Some develop fulminant liver failure with decompensation (ascites, encephalopathy etc.). Risk of developing chronic disease is low (<5%).
72
Serology of Hep B?
* HBsAg is detected 3-5 weeks after infection. If present for >6 months: Chronic disease (5-10% of infections). * Anti-HBs implies immunity- negative in chronic disease * Anti-HBc: previous or current infection. In current infection IgM raised for about 6 months, after will be IgG * HbeAg- marker of infectivity
73
Management of chronic Hep B?
* Pegylated interferon-alpha * Antivirals: tenofovir, entercavir and telbivudine
74
Features of Hep C?
Only 30% of people will develop features e.g.: * transient rise in serum aminotransfereases/ jaundice * fatigue * arthralgia
75
Investigations for Hep C?
* HCV RNA is the investigation of choice to diagnose acute infection * whilst patients will eventually develop anti-HCV antibodies it should be remembered that patients who spontaneously clear the virus will continue to have anti-HCV antibodies
76
What % of patients will go on to have chronic hep C?
* 55-85%
77
What is chronic Hep C?
* Persistence of HCV RNA in the blood for 6 months
78
Complications of chronic hep C?
* rheumatological problems: arthralgia, arthritis * eye problems: Sjogren's syndrome * cirrhosis (5-20% of those with chronic disease) * hepatocellular cancer * cryoglobulinaemia: typically type II (mixed monoclonal and polyclonal) * porphyria cutanea tarda (PCT): it is increasingly recognised that PCT may develop in patients with hepatitis C, especially if there are other factors such as alcohol abuse * membranoproliferative glomerulonephritis
79
Management of chronic Hep C?
* treatment depends on the viral genotype - this should be tested prior to treatment * the management of hepatitis C has advanced rapidly in recent years resulting in clearance rates of around 95%. * the aim of treatment is sustained virological response (SVR), defined as undetectable serum HCV RNA six months after the end of therapy * currently a combination of protease inhibitors (e.g. daclatasvir + sofosbuvir or sofosbuvir + simeprevir) with or without ribavirin are used
80
Complications of Chronic Hep C treatment?
ribavirin - side-effects: haemolytic anaemia, cough. Women should not become pregnant within 6 months of stopping ribavirin as it is teratogenic interferon alpha- no longer recommned - side-effects: flu-like symptoms, depression, fatigue, leukopenia, thrombocytopenia
81
What is Hep A?
Hepatitis A is typically a benign, self-limiting disease, with a serious outcome being very rare.
82

89
Causes of vomiting in newborns and infants? Mention some distinguishing factors.
* Overfeeding * GORD: may cause apnoea and failure to thrive, positional vomiting * Pyloric stenosis: 4-6 weeks old, projectile vomiting after feed, hungry after vomiting, palpable 'olive' in abdo * Whooping cough: paroxysmal cough * Small bowel obstruction e.g. congenital atresia or malrotation: bile stained vomit, presents soon after birth, may have distension * Constipation * Systemic: Menigitis, UTI/ pyelonephritis
90
Causes of vomiting in older children?
* Gastroenteritis: usually have diarrhoea, dehydration * Migraine * Raisied ICP: effortless vomiting, neuro signs, papilloedema * Bulimia * Toxic ingestion or medications * Pregnancy
91
Examination in child who is vomiting?
* Check for dehydration esp if presenting with GE * Abdo exam: feel for mass in neonates 'olive': pyloric stenosis, check for abdominal distension: intestinal obstruction * Neuro exam incl checking for papilloedema and HTN in cases of suspected raised ICP * Brudzinski and kernigs sign if suspecting meningitis
92
Investigations in vomiting?
Bedside: Urine dip- rule out UTI, ECG- may have electrolyte disturbances that can cause arrythmias, BM- check for DKA, CBG- metabolic disturbances Bloods: FBC- raised WCC for infection, U&Es- assess electrolyte disturbances and dehydration, CRP- for inflammation Imaging: pH monitoring and barium swallow-may show significant GORD, upper GI contrast study- if bilious vomiting in newborn- to exclude malrotation, USS of pylorus- if pyloric stenosis is suspected
