Study Notes

Endoscopy and Gastro-Oesophageal Reflux Disease (GERD)

Oesophageal biopsies can identify oesophagitis and rule out other vomiting causes.
Contrast studies of the upper gastrointestinal tract are not recommended for diagnosing GERD in young patients.
Uncomplicated GERD has a good prognosis; management includes parental reassurance and dietary adjustments such as smaller, more frequent feeds or using thickening agents (e.g., Carobel).
A 1-2 week trial of alginate therapy can be considered for persistent symptoms.
Medical management of GERD involves proton-pump inhibitors (e.g., omeprazole) or hydrogen receptor antagonists.
Surgery, specifically Nissen fundoplication, is only for children with complications unresponsive to medical treatment.

Case Study: Katie's GERD

11-month-old Katie experienced frequent regurgitation and had previous chest infections requiring hospitalization.
Endoscopy revealed oesophagitis, confirmed by histology.
Symptoms improved with a higher dose of omeprazole and the introduction of feed thickeners.
Functional constipation must be ruled out, as it can cause abdominal pain in children.

Functional Abdominal Pain Disorders (FAPDs)

FAPDs are classified into subcategories: irritable bowel syndrome (most common), abdominal migraine, functional dyspepsia, and unspecified functional abdominal pain.
Symptoms of irritable bowel syndrome include abdominal pain related to defecation and changes in stool frequency.
Distinguishing functional constipation from IBS can be challenging; pain resolves with constipation treatment indicates functional constipation.

Gastroenteritis

Major cause of child mortality in low- and middle-income countries; prevalent in hospital admissions for young children.
In high-income countries, common causes include viruses, primarily rotavirus (less common post-vaccination), now followed by norovirus, sapovirus, and entero-adenovirus.
Bacterial infections typically indicated by blood in stools; important pathogens include Campylobacter, Shigella, and certain Salmonella species.
Clinical assessment is not reliable for pathogen identification; focus on symptoms and hydration status.

Management of Gastroenteritis

Dehydration is the most serious complication; treatment prioritizes fluid replacement using oral rehydration solutions.
Avoid antidiarrheal medications in children, as gastroenteritis usually resolves within days.
Antibiotics are not routinely needed and only indicated for specific conditions or high-risk groups.
Nutritional management post-diarrhea involves continuing breastfeeding, reintroducing solids, and avoiding fruit juices.

Constipation in Children

Very common in children, particularly aged 2-4 years; can be broadly defined by stool frequency, hardness, and passing difficulties.
Symptoms indicative of constipation include fewer than three stools per week, painful defecation, and signs of faecal impaction.
Important to assess for changes in diet, dehydration, and anal fissures as potential causes.
Often resolves with appropriate dietary adjustments and increased fluid intake; monitoring growth and abdominal examination is essential.

Description

This quiz explores the diagnosis and management of Gastro-Oesophageal Reflux Disease (GERD) in pediatric patients, particularly focusing on endoscopy findings and treatment options. Through a case study of an 11-month-old, it illustrates key considerations in managing GERD, including dietary adjustments and medical interventions.
