Colitis, Collagenous: definition
Inflammatory bowel disorder characterized by microscopic inflammation of the large intestine consisting predominantly of lymphocytic infiltration and a thickened subepithelial collagen band (beneath the surface).
Inflammatory bowel disorder characterized by microscopic inflammation of the large intestine consisting predominantly of lymphocytic infiltration and a thickened subepithelial collagen band (beneath the surface).
A psychiatric condition characterized by abnormal social relations and is more characteristic of the classical infantile-onset CD, probably caused by nutritional deficits and toxic effects of severe malabsorption.
What Is Iron?I ron is an essential mineral that is required for normal body function.
Almost two-thirds of iron in the body is found in hemoglobin, the protein in red blood cells that carries oxygen to tissues. Smaller amounts of iron are found in myoglobin, a protein that helps supply oxygen to muscle, and in enzymes that assist biochemical reactions.
Iron is also found in proteins that store iron for future needs and that transport iron in blood.
Q: How are iron stores regulated?
A:Iron stores are regulated by intestinal iron absorption.1That is, whenever iron is needed, more iron is absorbed than when iron is sufficient. This mechanism prevents excess iron in the body which is harmful.
In the brain, iron is necessary to ensure oxygenation and to produce energy in the cerebral parenchyma (via cytochrome oxid. ase), and for the synthesis of neurotransmitters and myelin.
Iron concentrations in the umbilical artery are critical during the development of the fetus, and in relation with the IQ in the child.2
Schizophrenia is a thought disorder characterized by psychotic symptoms and inappropriate and bizarre behavior affecting cognitive function, interpersonal relationships, work or education, and self care.
What Is Epilepsy?E pilepsy is a dysfunctional disorder of the brain characterized by recurring seizures also called convulsions.
Q: What happens in a seizure?
A: During a seizure abnormal electrical discharges occur within the brain. Not all seizures have the same intensity or involvement.
Seizures can be generalized, partial or unclassified.

B ronchiectasis is a pulmonary disorder characterized by chronic dilation of bronchi (main airways) and bronchioles (small airways) with chronic inflammation and swelling, increasing the risk of infection.
In bronchiectasis, mucus produced to trap foreign substances, such as dust and bacteria, builds-up because the ability of airways to move it out is impaired. Normally, hair-like cilia that line airways beat mucus out of the lungs. Loss of this action increases mucus in the airways which increases risk of pneumonia.
The anatomy of airways is likened to a branching tree. The trachea, or windpipe, like the trunk of a tree, branches into two primary bronchi that connect it to the lungs. One bronchus connects to the left lung and the other to the right lung. Each bronchus further divides into smaller bronchi that connect to the lobes. Lobes are large subdivisions of lung tissue: two of the left lung and three of the right lung.
Lobe bronchi divide into smaller bronchial tubes ending in small bronchioles. The ends of bronchioles are surrounded with and attached to tiny alveoli which are air sacs that look like clusters of grapes.
Q: What effect does inflammation have on the lungs?
A: Alveoli are only one cell thick, where oxygen is obtained by the bloodsteam from air breathed into them and carbon dioxide is released from the bloodstream to air that is breathed out of air sacs through the pulmonary tree. Two things happen:
Bronchiectasis can affect one or both lungs or one segment or multiple segments of a lung. Treatment is with antibiotics, chest physiotherapy and good nutrition.

O cular myopathy is an impairment of musculature of the eyeball that is characterized by abnormalities of eye movement that make initiating and maintaining eye movement and eye contact difficult.

K idney stones, also called renal calculi, are abnormal hard formations in the kidneys that are composed mainly of calcium oxalate, also uric acid, and cystine.
Q: How big are kidney stones?
A: Stones can vary in size from microscopic crystals to several centimeters in diameter.
Some stones that are able to enter a ureter can cause excruciating pain while small stones can pass out with urine unnoticeed. A ureter is a tube that connects a kidney to the bladder for the purpose of removing urine. There are two ureters, one for each kidney.
What Is Developmental Delay?D evelopmental delay is failure in infants and young children to meet expected milestones, such as smiling for the first time or taking the first steps, due to an impairment in physical, learning, language, or behavior areas.
These conditions begin during the developmental period, may impact day-to-day functioning, and usually last throughout a person’s lifetime.1
