Our job is to problem solve:
(And have an open mind)
Research and clinical studies are simply there to give
us added guidance: They are a piece of the
puzzle, not the whole puzzle
![Page 3: Thinking Outside the Box - Constant Contact](https://reader031.fdocuments.us/reader031/viewer/2022012518/6193121a8706485c3a0a0837/html5/thumbnails/3.jpg)
What are we Treating?
Is Colic a Diagnosis? Is Reflux a diagnosis?
GE reflux, esophagitis, gastritis
Gastric dysmotility, gastroparesis
Intestinal dysmotility (dysfunction), dumping syndrome
Bacterial/fungal overgrowth, dysbiosis
Food sensitivities
Pancreatitis
Is the problem in the GI tract?

Oral Motor Problems
Swallow Breathing and “Body Mechanics”
![Page 9: Thinking Outside the Box - Constant Contact](https://reader031.fdocuments.us/reader031/viewer/2022012518/6193121a8706485c3a0a0837/html5/thumbnails/9.jpg)
Mechanical activity • Stomach
Chemical/Enzymatic activity • Oral: amylase, proteases, lipase
• Stomach: HCL, Pepsin, Lipases
• Pancreatic: HCO3, Proteases, Lipases, Amylase
• Biliary: Bile acids, Phospholipids
• Intestinal mucosa: Breakdown of protein and CHO fragments
Bacterial activity • Primarily in Colon: For their benefit and ours
Digestive system is operational in infants (including gastric acidity)
Digestion
![Page 10: Thinking Outside the Box - Constant Contact](https://reader031.fdocuments.us/reader031/viewer/2022012518/6193121a8706485c3a0a0837/html5/thumbnails/10.jpg)
The GI tract accounts for the greatest contact (surface area) with the outside world
60-70% of total bodies Immune system is in the GI tract
Systems:
• Physical barrier:
Physical integrity of mucosal lining
Stomach acidity
Enzymatic activity
• Bacterial flora play a role in gut immunity
• Cellular and humoral immune system
In state of mild chronic controlled inflammation
Must have tolerance to “safe foods, bacteria, etc”
Must React appropriately to pathogenic and harmful organisms
Inflammation has effects on motility and absorption
Immunity: Immune system and
Tolerance

How Do We Diagnosis?
Pattern recognition
Diagnostic Tests as confirmation… Maybe?
Like everything else, diagnostic tests are only a
piece of the puzzle
![Page 16: Thinking Outside the Box - Constant Contact](https://reader031.fdocuments.us/reader031/viewer/2022012518/6193121a8706485c3a0a0837/html5/thumbnails/16.jpg)
Diagnostic Studies
Contrast radiology studies
Anatomic detail
Radioscintigraphy (Tc scan)
Chalasia scan
Gastric emptying scan
Esophageal pH monitoring
Is acid going up the esophagus
Endoscopy
details of anatomy and histology
Esophageal and antroduodenal manometry
Motility - rarely used and rarely needed
![Page 17: Thinking Outside the Box - Constant Contact](https://reader031.fdocuments.us/reader031/viewer/2022012518/6193121a8706485c3a0a0837/html5/thumbnails/17.jpg)
Clinical Presentation and
Empiric Treatment
Empiric Treatment: “Personal Opinion” The quickest, most reliable path to diagnosis
Quicker time to diagnosis and relief
Least invasive
Inexpensive
![Page 18: Thinking Outside the Box - Constant Contact](https://reader031.fdocuments.us/reader031/viewer/2022012518/6193121a8706485c3a0a0837/html5/thumbnails/18.jpg)
Let’s Look at
Gastroesophageal Reflux
![Page 19: Thinking Outside the Box - Constant Contact](https://reader031.fdocuments.us/reader031/viewer/2022012518/6193121a8706485c3a0a0837/html5/thumbnails/19.jpg)

A Way of Thinking
Is There Something Other
Than Reflux Going On?
Gastroesophageal Reflux ( The Root of Reflux)
![Page 28: Thinking Outside the Box - Constant Contact](https://reader031.fdocuments.us/reader031/viewer/2022012518/6193121a8706485c3a0a0837/html5/thumbnails/28.jpg)
There May be One or More
Contributing Factors
Anatomic problems
Dysmotility
Metabolic problems
Food Sensitivity/Allergy
Poor mucosal Integrity (Leaky Gut)
Dysbiosis
![Page 29: Thinking Outside the Box - Constant Contact](https://reader031.fdocuments.us/reader031/viewer/2022012518/6193121a8706485c3a0a0837/html5/thumbnails/29.jpg)
Dysmotility: Formula
Modification
Considerations:
Osmolality: Increased
osmolality delays gastric
emptying
Whey protein: Increased
emptying
MCT oil vs LCT
![Page 30: Thinking Outside the Box - Constant Contact](https://reader031.fdocuments.us/reader031/viewer/2022012518/6193121a8706485c3a0a0837/html5/thumbnails/30.jpg)
Constipation
Definition: A deviation from the norm in stool frequency
(decreased), consistency (harder), or difficulty with
passage of stool resulting in clinical problems.
Symptom presentation may include:
Abdominal distention/pain
Nausea/emesis
Anorexia/decreased appetite
(All symptoms of GE reflux)
![Page 31: Thinking Outside the Box - Constant Contact](https://reader031.fdocuments.us/reader031/viewer/2022012518/6193121a8706485c3a0a0837/html5/thumbnails/31.jpg)
Is Constipation Causing Problems?
“You have to make the package and
deliver it”
Sometimes you can’t tell from the history so: Empiric trial
Older child
Miralax: to make the package
Senna: to deliver
Infant or tolerant child
Glycerin suppositories
Always ask the question: Is there a root to this problem? or what’s causing the constipation?
![Page 32: Thinking Outside the Box - Constant Contact](https://reader031.fdocuments.us/reader031/viewer/2022012518/6193121a8706485c3a0a0837/html5/thumbnails/32.jpg)
Elimination (Stooling)
Preterm infant in the NICU
Unable to come off of IV Nutrition
Stooling at least daily
Administration of rectal suppositories 2 x
daily
Within 2 weeks on full enteral feedings
![Page 33: Thinking Outside the Box - Constant Contact](https://reader031.fdocuments.us/reader031/viewer/2022012518/6193121a8706485c3a0a0837/html5/thumbnails/33.jpg)
Bacterial/Yeast Overgrowth
Risk factors
Poor motility
Acid suppression

Absence of ileocecal valve
Problem - malabsorption
Mucosal inflammation
Deconjugation of bile salts
May compete for nutrients
Typical GI symptoms
Bloating
Cramps
Diarrhea
Nausea
GE Reflux
Extra GI Symptoms
A rise in Microbial counts in the small intestine
![Page 34: Thinking Outside the Box - Constant Contact](https://reader031.fdocuments.us/reader031/viewer/2022012518/6193121a8706485c3a0a0837/html5/thumbnails/34.jpg)
Bacterial/Yeast Overgrowth (and
Dysbiosis)
Antibacterial/antifungal
Drug therapy
Antimicrobial oils
Dilated small bowel
Absence of ileocecal valve
Probiotics
Change diet
Vegetable fibers vs starches and sugars
Further improve local ecology
Calm immune system
Improve function of mucosal barrier
What to do
![Page 35: Thinking Outside the Box - Constant Contact](https://reader031.fdocuments.us/reader031/viewer/2022012518/6193121a8706485c3a0a0837/html5/thumbnails/35.jpg)
Dysmotility and PPI use are
independent risk factors for small
intestinal bacterial and/or fungal
overgrowth

Protein Intolerance/Food
Allergies Predisposition
Immature mucosal defense system (Preterm infant)
Increased permeability Prematurity
Malnutrition
Infectious enteritis
Bowel injury or compromise
Treatment
Hydrolysate or elemental formula, cow’s milk or soy elimination from maternal diet
![Page 37: Thinking Outside the Box - Constant Contact](https://reader031.fdocuments.us/reader031/viewer/2022012518/6193121a8706485c3a0a0837/html5/thumbnails/37.jpg)
For Formula Fed Infant/Child:
Changing the formula
• No relief will occur by switching to formulas using same protein source
Milk allergy is an adverse response to protein:
Four Main Classes of Formula
• Milk (Casein or Whey)-based basic formulas
• Soy-based formulas
• Partially or extensively hydrolyzed protein formulas
• Amino acid-based formulas
• Milk protein is intact in lactose-free milk
• Lactose-free does not resolve the problem as milk protein
remains intact
![Page 38: Thinking Outside the Box - Constant Contact](https://reader031.fdocuments.us/reader031/viewer/2022012518/6193121a8706485c3a0a0837/html5/thumbnails/38.jpg)
Removing the Protein Allergen
All basic formulas (dairy + soy) are made of complete
protein chains that trigger allergic reactions.
Hydrolysate formulas break the protein chain into pieces. This is better tolerated by many, but can still trigger an allergic reaction. Amino Acid-based formulas are made with individual non-allergenic amino acids. They are very well tolerated and classified as hypoallergenic.
Most
Allergenic
Least
Allergenic
Basic Infant formula and breast milk contain whole proteins
Reaction to Hydrolysates is more common than realized
![Page 39: Thinking Outside the Box - Constant Contact](https://reader031.fdocuments.us/reader031/viewer/2022012518/6193121a8706485c3a0a0837/html5/thumbnails/39.jpg)
Improving Treatment
of Dairy and Soy Milk Protein Allergy
A Diagnostic Approach to Treating Milk
Protein Sensitivity
All Infants with suspected milk protein allergy symptoms
14-day trial with amino acid-based formula
If unsure, continue for a week or 2 longer or return to previous
formula
![Page 40: Thinking Outside the Box - Constant Contact](https://reader031.fdocuments.us/reader031/viewer/2022012518/6193121a8706485c3a0a0837/html5/thumbnails/40.jpg)
The Older Child with Food
Allergy/Intolerance
Similar set of symptoms as infant
Testing is difficult
Diagnosis/Treatment is also sometimes difficult
Elimination diet is often needed
Rotation diet works for some
Dietician is vital
Enzymes?
![Page 41: Thinking Outside the Box - Constant Contact](https://reader031.fdocuments.us/reader031/viewer/2022012518/6193121a8706485c3a0a0837/html5/thumbnails/41.jpg)
The Older Child with Food
Allergy/Intolerance: Testing
Skin (Prick skin test)
Positive predictive value is <50%
Negative Predictive value is >95% (les than age 3 yrs. 80-85%)
Need to be off anti-histamines
RAST testing
Quantitative
Less sensitive than skin testing
May be useful for re-evaluating child’s allergy
![Page 42: Thinking Outside the Box - Constant Contact](https://reader031.fdocuments.us/reader031/viewer/2022012518/6193121a8706485c3a0a0837/html5/thumbnails/42.jpg)
The Eosinophilic
Gastroenteropathies
(eosinophilic esophagitis,
gastroenteritis and
proctocolitis)
Severe eosinophilic esophagitis might lead to esophageal
strictures
Diagnosis by endoscopic biopsy
Thought to be primarily allergic in origin
Primary treatment is recognition and elimination of allergens

Sun Si Miao (Chinese physician, 6th century)“before
considering acupuncture and herbs, the physician should first
address the diet and lifestyle”.
