Study Notes
Pediatric Gastrointestinal Disorders Overview
- Acute diarrhea is a leading cause of illness in children under 5 years of age
- Chronic diarrhea is defined as increased stool frequency and water content for more than 14 days
- Most diarrhea-causing pathogens spread through contaminated food, water, or person-to-person contact
- Oral rehydration therapy (ORT) is a major worldwide health advance, reducing vomiting, diarrhea, and illness duration
- Constipation can be idiopathic or secondary to other disorders
- Hirschsprung disease is characterized by mechanical intestinal obstruction and presents with various symptoms
- Gastroesophageal reflux (GER) can lead to respiratory symptoms and complications
- Intestinal parasitic diseases are caused by various organisms and present with specific symptoms
- Acute appendicitis presents with periumbilical pain, nausea, right lower quadrant pain, vomiting, and fever
- Meckel's diverticulum is the most common congenital malformation of the GI tract and can lead to complications
- Inflammatory bowel disease (IBD) includes ulcerative colitis and Crohn's disease and requires medical, nutritional, and surgical treatment
- Peptic ulcer disease (PUD) can manifest as gastric or duodenal ulcers and may be primary or secondary
Pediatric Gastrointestinal Disorders Overview
- Diagnostic methods for gastrointestinal disorders include laboratory tests, endoscopy, and radiographic studies.
- Therapeutic management for gastrointestinal disorders involves relieving pain, preventing complications, and recurrence through medications and procedures such as antacids, histamine receptor antagonists, and PPIs.
- Hepatitis can be acute or chronic and is caused by various factors including viruses, metabolic issues, and neoplastic conditions.
- Hepatitis A, B, and C require different therapeutic management, with HAV being acute and resolving with symptom management, HBV requiring medications to reduce viral load, and HCV being curable with antivirals.
- Cirrhosis is late-stage liver damage of chronic liver diseases and can be managed through monitoring liver function and managing complications, with liver transplant improving prognosis.
- Biliary atresia is a progressive inflammatory process that leads to ductal obstruction and can be diagnosed through laboratory tests, ultrasound, and HIDA scan.
- Cleft lip and cleft palate are facial malformations that occur during embryonic development and can be managed through surgical correction.
- Esophageal atresia and tracheoesophageal fistula are conditions where the esophagus or trachea fail to develop properly and may require surgical intervention.
- Hernias, such as diaphragmatic, hiatal, and umbilical, are protrusions of organs through abnormal openings and carry the danger of incarceration or strangulation.
- Omphalocele and gastroschisis are congenital defects in the abdominal wall, with omphalocele involving the protrusion of intra-abdominal viscera into the base of the umbilical cord and gastroschisis involving protrusion through a defect in the abdominal wall.
- Obstructive disorders impede the passage of nutrients and secretions, leading to symptoms such as colicky abdominal pain, abdominal distension, vomiting, constipation, and dehydration.
- Pediatric malabsorption syndromes are characterized by chronic diarrhea and malabsorption of nutrients, with celiac disease being an example and presenting with steatorrhea, malnutrition, abdominal distention, and secondary vitamin deficiencies.
