Study Notes
Tropical Sprue/Enteropathy
- Etiology is unknown but often involves bacterial overgrowth in the large intestine.
- Damage to the mucous membrane occurs due to fermentation, leading to atrophy and malabsorption.
- Results in deficiencies of folate and vitamin B12.
- At-risk individuals include those traveling to equatorial countries and adults more so than children.
- Clinical manifestations include bloody diarrhea, abdominal distention, and steatorrhea (fat in stool).
- Treatment options are antimicrobials, antidiarrheals, and vitamin/electrolyte supplements.
Dumping Syndrome
- Occurs post-gastrectomy and gastric surgeries; due to loss of pyloric sphincter regulation.
- Rapid entry of partially digested food into the intestine can trigger osmotic diarrhea.
- Clinical manifestations include diarrhea, abdominal pain, and a rapid decline in blood glucose levels.
- Treatment includes eating smaller, more frequent meals throughout the day.
Short Bowel Syndrome
- Results from the surgical removal of a significant portion of the intestines, leading to malabsorption.
- Severe diarrhea is a common symptom, particularly if the ileocecal valve is removed.
- Clinical management is largely supportive, focusing on nutrient intake.
Inflammatory Bowel Disease (IBD)
- Crohn's disease affects the proximal part of the colon or terminal ileum with chronic inflammation across all layers of the intestinal wall.
- Caused by obstruction and inflammation of lymph vessels, leading to ulcers, strictures, and fistulas.
- Clinical signs include fever, diarrhea, right lower quadrant pain, and tenderness.
Disorders of the Mouth
- Stomatitis refers to ulcerative inflammation of the oral mucosa, caused by various factors including infections and irritants.
- The most common type is herpetic gingivostomatitis, frequently affecting children, caused by the herpes simplex virus (HSV).
- Symptoms include tingling and painful ulcers; HSV can remain dormant and reactivate later.
- Treatment involves antivirals/antibiotics for infections and corticosteroids for autoimmune causes.
Hiatal Hernia
- Occurs when the stomach protrudes into the chest cavity through the diaphragm.
- Risk increases with age; women are more affected than men.
- Two types:
- Sliding hernia involves movement of the stomach with the gastroesophageal junction.
- Paraesophageal hernia, where the stomach's greater curvature pushes through.
- Risk factors include increased intra-abdominal pressure due to pregnancy, obesity, and chronic cough.
Other Conditions
- Intussusception occurs when one segment of the bowel telescopes into another, leading to obstruction; more common in infants and males.
- Symptoms in children may include profuse diarrhea, hypovolemic shock, and intestinal perforation.
- Hirschsprung disease is a congenital condition with reduced or absent autonomic ganglia, causing difficulty in stool passage in newborns.
