Study Notes
Celiac Disease
- Autoimmune disorder triggered by gluten ingestion
- Damage to the small intestine's lining
- Most common in children with type 1 diabetes, Down syndrome, Turner syndrome, autoimmune thyroiditis, and other autoimmune diseases
- Symptoms can be non-specific, including abdominal pain, diarrhea, and weight loss
- Diagnosis relies on a biopsy of the small intestine which shows villous atrophy
- Management involves lifelong adherence to a gluten-free diet
Celiac Disease Management
- Consultation with a dietitian for dietary guidance
- Education about the disease and its management
- Lifelong compliance with a gluten-free diet
- Identifying and treating nutritional deficiencies
- Access to advocacy groups or health behavior support
- Continuous long-term follow-up with a gastroenterologist to monitor growth and nutrition
Celiac Disease Complications
- Growth failure is a primary concern
- Osteoporosis increases the risk of fractures
- Cancer, particularly lymphoma, is a possible long-term risk
- Celiac crisis is a rare but serious complication characterized by severe symptoms, requiring immediate medical attention
Irritable Bowel Disease (IBD)
- Immune-mediated disease marked by alternating periods of inflammation and remission
- The most common forms of IBD are Crohn's disease and ulcerative colitis
Crohn's Disease
- Transmural inflammation (affects all layers of the intestinal wall)
- Skip lesions, meaning inflammation can occur in patches throughout the digestive tract
- Inflammation can occur anywhere from the mouth to the anus
Ulcerative Colitis
- Inflammation is limited to the mucosal layer of the colon
- The most common symptom is bloody diarrhea
Irritable Bowel Disease Symptoms
- Abdominal pain, cramping, and tenderness, particularly in the right lower quadrant
- Tenesmus, the urge to stool due to inflammation of nerves in the rectum
- Fatigue
- Diarrhea, often bloody
- Fever during flares
- Growth restriction and weight loss
- Anemia, leukocytosis, hypoalbuminemia, elevated calprotectin, and elevated inflammatory markers
- Perianal disease including fissures, skin tags, hemorrhoids, and fistulae
- Oral ulcerations such as aphthous stomatitis
- Rashes like erythema nodosum or pyoderma gangrenosum
- Uveitis, inflammation of the eye
- Hepatitis and jaundice
- Arthritis
Irritable Bowel Disease Diagnosis
- Endoscopy is the first-line test for any child with rectal bleeding or perianal disease (includes upper and lower GI series and multiple biopsies)
- Blood tests: CRP, Hgb, calprotectin (intestinal inflammation marker)
- Stool tests: enteric pathogens, fecal calprotectin
- Imaging: Magnetic resonance enterography (MRE), the gold standard detects inflammatory changes, but if the child cannot cooperate with the test, computed tomography enterography (CTE) may be used
Irritable Bowel Disease Differential Diagnosis
- Functional abdominal pain (IBS, constipation, etc.)
- Anal fissures, polyps, hemorrhoids
- Henoch-Schonlein purpura (IgA vasculitis)
- Meckel's diverticulum
- Milk protein-induced proctocolitis (infants)
- Celiac disease
- Enteric pathogens
- Intussusception

Functional Abdominal Pain Physical Examination
- Growth charts
- Hydration status
- Abdomen examination to assess bowel sounds, percussion, palpation, and peritoneal irritation
- Walk, jump, cough, and heel-jar maneuvers
- Rebound tenderness, Rovsing's sign (palpating the left iliac fossa elicits pain in the right iliac fossa)
- Obturator and psoas signs
- Rectal and gynecologic exams as needed
Functional Abdominal Pain Diagnosis
- Thorough history and physical examination
- Complete blood count (CBC) with differential
- Urinalysis (UA) and culture
- Serum chemistry screen (including liver and lipid profiles)
- Erythrocyte sedimentation rate (ESR)
- C-reactive protein (CRP)
- Thyroid function tests
- Stool analysis: O&P (ova and parasites), culture, blood, WBCs, pH, reducing substances
- Fecal fat collection for 72 hours to rule out malabsorption
- Serum IgA, IgG, and TTG (tissue transglutaminase) antibodies to rule out celiac disease
- Other relevant tests based on clinical findings
- Pregnancy test, Pap smear, vaginal cultures, and gonorrhea and chlamydia (G&C) testing if sexually active
- Ultrasound and esophageal pH monitoring if red flags are present

- Crampy or dull pain without radiation
- Pain is typically periumbilical in location
- Pain is not relieved by anything
- Pain interferes with activities
- No night awakenings
- Pain is not food-related
- Normal growth
- Afebrile (no fever)
- Generalized tenderness to the abdomen without guarding
- Overall normal physical examination
Functional Abdominal Pain Management

- Maintaining a pain diary
- Exploring psychological triggers and management strategies
- Regular follow-up appointments

Hirschsprung's Disease
- A rare congenital abnormality resulting in intestinal obstruction and megacolon (dilated colon)
- Also known as congenital aganglionic megacolon
- It is caused by a lack of nerve cells (ganglia) in a segment of the colon, usually in the distal portion
- This leads to inadequate motility of the intestine
- Usually occurs in full-term infants with a history of delayed passage of meconium within 24-48 hours
- More common in males, approximately 4 times more frequent
- Symptoms can be present at birth or appear later in life
Hirschsprung's Disease Symptoms
- Newborn with delayed passage of meconium
- History of chronic constipation since birth with ribbon-like, foul-smelling stools
- Bilious vomiting
- Abdominal distention (sometimes with visible peristalsis)
- Poor feeding or failure to thrive (FTT)
- Poor weight gain
- Episodes of vomiting and diarrhea
- Explosive watery diarrhea
- Fever and exhaustion are signs of enterocolitis
Hirschsprung's Disease Diagnosis
- Rectal biopsy: absence of ganglion cells confirms the diagnosis
- Abdominal radiograph: shows dilated loops of bowel
- Barium enema: shows a transition zone between the normal, dilated proximal colon and the smaller, obstructed distal colon, with delayed evacuation of barium
- Anorectal manometry: not routinely done in infants, measures pressure and how the rectum functions
- Laboratory tests are not usually necessary unless the child is febrile
Hirschsprung's Disease Management
- Surgical procedure to remove the affected tissue (most often in the sigmoid colon area) followed by a pull-through procedure to connect healthy tissue
- Ostomy is rarely required
- As a primary care physician, monitor dietary intake, stool patterns for fecal continence, and watch for enterocolitis, perianal abscess, prolapse, strictures, and fecal soiling
Chronic Diarrhea
- Persistent or prolonged diarrhea that starts as acute diarrhea and affects growth
- Refer to Table 34-11 for common bacterial and viral causes, diagnosis, and management
- Refer to Table 34-12 for common conditions broken down by age group

Chronic Diarrhea Clinical Findings
- Three or more stools daily for more than 2 weeks
- Ten watery or loose stools per day containing undigested food particles, suggestive of "toddlers' diarrhea"
- Red flags: anemia, weight loss, persistent fever, blood in stools
Chronic Diarrhea History and Physical Examination
- Diet, travel history, recent illnesses, medications, exposures (daycare)
- Diarrhea that does not improve with fasting
- Hydration status, weight, growth, vital signs, abdominal and rectal examinations (as indicated)
Chronic Diarrhea Treatment
- Treat the underlying cause
- Chronic nonspecific (toddlers') diarrhea: juice intake, diet normalization
- Post-gastroenteritis malabsorption: trial of predigested formula (Pregestimil or Alimentum) for infants
- Referral to gastroenterology as needed
Malabsorption
- Lactose intolerance: secondary to lactase enzyme deficiency
- Gold standard testing: lactose hydrogen breath test, no antibiotics at the time of the study

- Similar presentations, but CMPI is a non-allergic hypersensitivity to cow's milk protein, while CMPA is a mostly IgE-mediated atopic disease
Cow's Milk Protein Allergy (CMPA)
- Immediate and allergic reaction: respiratory, skin, and GI symptoms
- Late onset: primarily GI symptoms, including bloody stools, nausea, vomiting, diarrhea, rash, and eczema
Cow's Milk Protein Intolerance (CMPI) and Cow's Milk Protein Allergy (CMPA) Diagnosis
