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.
