Small bowel intussusception is a bowel derangement that is characterized by the slipping of one section of intestine into another, leading to bowel obstruction.
Acute bowel intussusception is a rare manifestation in adults, which mainly involves the small intestine.1

What Is Food Allergy?
Food allergy is an abnormal immune response to food proteins that may damage the small intestinal lining and produce malabsorption of food. The reaction is usually delayed which makes it difficult to identify the offending food that is causing symptoms.
Q: How does food allergy develop?
A: The gastrointestinal tract serves not only to digest and absorb foodstuffs but also to protect the body from unwanted substances. When allergic food substances are eaten, the immune response that is triggered in the gut produces inflammation with symptoms such as pain, vomiting and loose bowels.
Inflammation causes swelling of the gut lining that can interfere with the passage of nutrients through it to the body which results in malabsorption. Malabsorption deprives the body of nutrients needed for normal function.
Symptoms other than digestive may involve skin rashes, hives, and respiratory difficulties that can be distressing and life-threatening.

Riboflavin, also called vitamin B2, is fundamentally required for the breakdown of carbohydrates, amino acids, and fats in metabolism, enables oxygen to be used by cells, and acts as a component of more than a dozen enzymes involved in energy production and use.
Some enzymes needing riboflavin also require magnesium to properly function.
In other activities, riboflavin is required for healthy cardiovascular and nervous systems, eye health, and supports antioxidant protection. Functions are more fully described below.
Urinary excretion of riboflavin cannot be detected when vitamin intake is below the required levels. On the other hand, when intake exceeds saturation in the body, the vitamin and/or its metabolites are actively excreted into urine to prevent excessive toxicity of the vitamins.1
There is no specific name for riboflavin deficiency disease.

L ow cholesterol found in blood indicates an abnormal blood level of this essential lipid (fat) that is characterized by decreased production of steroid hormones and bile.
Cholesterol is a soft, fat-like substance found in the bloodstream and is an essential structural component in all body cells. It is required for membrane fluidity and permeability of cells. Within the cell membrane, cholesterol also functions in intracellular transport, cell signaling and nerve conduction.
Cholesterol is required for these essential body processes:
Cholesterol is converted to bile by the liver and stored in the gallbladder until needed for digestion of fats in the small intestine.
Cholesterol is used by the adrenal glands to produce the steroid hormones cortisol and aldosterone.
Cholesterol is used by the sex glands to make progesterone, estrogen, and testosterone and their derivatives.
Cholesterol is needed for the production of vitamin D.
Q: What makes cholesterol bad for you?
A: There are different forms of cholesterol that can be bad or good depending on the level. In blood vessels, low-density lipoprotein (LDL or ‘bad’) cholesterol can abnormally join with fats and other substances to build up in the inner walls of arteries. The arteries can become clogged and narrow, and blood flow is reduced. This is atherosclerosis which can lead to stroke, heart attack and thrombosis.
High-density lipoprotein (HDL or ‘good’) carries harmful cholesterol away from the arteries and helps protect from heart attack and stroke.1

Chronic ulcerative jejunitis is a disease of the small intestine that is characterized by inflammation and ulceration of the mucosal lining of the jejunum.
Q: How do inflammation and ulceration affect digestion in the jejunum?
A: Inflammation swells the lining and this impairs absorption of nutrients. Together with ulceration the inflamed and swollen jejunum hampers peristalsis, or the rhythmic movement of food by intestinal muscles.
Impaired peristalsis promotes constipation and/or diarrhea. Bacterial overgrowth may develop. Ulcerations may bleed which could cause the development of iron deficiency anemia.

Geographic tongue is a painful alteration in tongue tissue that is characteristic of riboflavin (vitamin B2) deficiency.1
Q: How does the tongue surface appear?
A: Areas of inflamed tissue with flattened papillae develop among areas of normal tissue, giving a map-like appearance to the tongue surface. There are often swollen papillae that hurt or sting, such as is seen in the photo to the left.
A diet that does not provide adequate amounts of riboflavin and any condition that 1) interferes with riboflavin absorption from the gut, 2) depletes the vitamin from the body, 3) overuses the vitamin in the body, or 4) adversely affects its use in the body will result in riboflavin deficiency causing geographic tongue.
Riboflavin is essential for converting foodstuffs into energy, maintaining the normal lifespan of red blood cells and maintaining healthy skin, eyes, hair, and nervous system. Riboflavin is converted into its active forms, flavin adenine dinucleotide (FAD) and flavin mononucleotide (FMN). These enzymes are primarily involved as co-factors in oxidation reduction reactions that are essential for cellular energy production and respiration.
Riboflavin is required for the conversion of pyridoxine (vitamin B6) to its functional form and the production of niacin (vitamin B3) from the amino acid tryptophan. Riboflavin has a role in antioxidant status by activating glutathione reductase, which regenerates used glutathione, a powerful antioxidant.
Respiratory infection, exercise, certain diseases, drugs and hormones can adversely influence riboflavin status.2 Stress is a major depleter of riboflavin.

What Is Primary Sclerosing Cholangitis?
Primary sclerosing cholangitis (PSC) is an uncommon, slowly progressive bile duct disease that results in stagnation or build-up of bile in the liver, called cholestasis.
Primary sclerosing cholangitis is characterized by sclerosis, or scarring inflammation in bile ducts both within the liver (intra-hepatic ducts), and outside the liver (extra-hepatic ducts), causing progressive narrowing and, eventually, obliteration of the bile ducts.
Primary sclerosing cholangitis comes under the umbrella term autoimune liver disease in which the end result is immune-mediated hepatocellular (liver cell) or hepatobiliary (bile duct) injury.1
Q:What happens when scarred bile ducts can no longer transport bile out of the liver?
A:Bile that cannot be removed from the liver by the biliary duct system backs up and damages the liver, causing cirrhosis.
Bile is continually made by the liver from phospholipids salt, cholesterol, and aging blood cells that it removes from circulation to be carried out of the liver. Bile also carries away waste products produced by normal metabolism and toxic substances that are removed by the liver for eventual elimination in stool. As such, bile must continually flow out of the liver to prevent build-up in the liver.
Bile is a greenish brown liquid made by the liver. Bile ducts carry it out of the liver to the gall bladder for storage until needed to aid in the digestion and absorption of fat from the small intestine. Bile emulsifies fat eaten in the diet so that the pancreatic enzyme called lypase can break it down into its fatty acid and glycerol components.
The liver is the largest organ within the body. It lies mostly in the upper part of the abdomen on the right side just under the diaphragm. About 70% of liver tissue is made up of cube shaped cells called hepatocytes that do the main work of the liver. Other cells (epithelial) form structure and are arranged in single layers around blood vessels, sinusoids, and bile ducts.
Build-up of bile in the liver is the end result of the inflammatory process in primary sclerosing cholangitis, that by swelling and scarring of bile ducts impedes and eventually prevents bile flow out of the liver, leading to liver failure. There is no curative treatment available for primary sclerosing cholangitis, besides liver transplantation.2
The appearance of the intrahepatic and extrahepatic biliary ducts can be assessed by use of cholangiography, and magnetic resonance (MR) imaging is the best way to identify patients. See image above.3
MR cholangiography offers a noninvasive method of obtaining images of the biliary system without the use of a contrast agent. There is no radiation exposure. Pulse sequences can be chosen to obtain bright bile or black bile cholangiograms. Image processing algorithms can be selected to obtain a three-dimensional representation of biliary anatomy and pathology, and those images can be rotated in any plane so that ductal anatomy and pathology can be seen to best advantage.4
There is no cure for primary sclerosing cholangitis but there are symptom treatments one of which is supplementation for low levels of vitamins A,D,E, and K. Liver transplant is the only effective option.

What Is Small Intestinal Edema?
Small intestinal edema is characterized by fluid accumulation within the intestinal mucosa so that the intestinal wall appears thick and swollen.
Intestinal edema hampers peristalsis that can result in pain and gas build-up. Peristalsis is the normal rhythmic muscular wave-like action that moves residue along the gastrointestinal tract.
Q: What part of the small intestinal lining is swollen?
A: Any part of the small intestine may be affected. Some causes of edema include allergic reactions, enteropathies such as celiac disease, cow milk enteropthy, yeast infection, parasite infection, inflammatory bowel disease such as Crohn’s disease, and certain medications.
For example, the anti-hypertensive drugs known as Angiotension Converting Enzyme (ACE) inhibitors can cause intestinal angioedema and therefore the patient may present with gastrointestinal complaints.1
