These cells produce specific chemicals like serotonin, substance P, neuropeptide K, and neurokinin A. Enterochromaffin cells can be found in the intestines, appendix, rectum, lungs, stomach, pancreas, and thyroid. The carcinoid syndrome causes facial flushing, diarrhea and heart valve abnormalities. How Carcinoid Syndrome Causes Facial Flushing The facial flushing caused by carcinoid syndrome varies with the location of the tumor. The most common flush occurs in the head and neck area in response to excitement, exercise, drinking alcohol, and eating. It usually lasts only minutes. The flushing is caused by the sudden release of the chemicals produced by the enterochromaffin cells. Carcinoid syndrome is diagnosed by a specialized urine test that measures a chemical called 5-HIAA. Treatment of Facial Flushing With Carcinoid Syndrome The facial flushing of carcinoid syndrome is treated by removal of the tumor and administering a medication called

In 1942, Dr. Harry Klinefelter and his coworkers at the Massachusetts General Hospital in Boston published a report about nine men who had enlarged breasts, sparse facial and body hair, small testes, and an inability to produce sperm. By the late 1950s, researchers discovered that men with Klinefelter syndrome, as this group of symptoms came to be called, had an extra sex chromosome, XXY instead of the usual male arrangement, XY. In the early 1970s, researchers around the world sought to identify males having the extra chromosome by screening large numbers of newborn babies. One of the largest of these studies, sponsored by the National Institute of Child Health and Human Development (NICHD), checked the chromosomes of more than 40,000 infants. Based on these studies, the XXY chromosome arrangement appears to be one of the most common genetic abnormalities known, occurring as frequently as 1 in 500 to 1 in 1,000 male births. Although the syndrome's cause, an extra sex chromosome, is widespread, the syndrome itself-the set of symptoms and characteristics that may result from having the extra chromosome-is uncommon. Many men live out their lives without ever even suspecting that they have an additional chromosome.

Cockayne syndrome is an inherited disorder in which the genetic material (DNA) in body cells is damaged by ultraviolet radiation. Normally, the body can repair DNA damaged by sunlight, but people with Cockayne syndrome lack the ability to do that. What are the symptoms? There are two forms of Cockayne syndrome. The classic type, Type I, becomes apparent after the child is about a year old. Type II, or severe Cockayne syndrome, is apparent at birth. Because Cockayne syndrome affects many types of body cells, it affects many body systems. Some of its symptoms are: pinched, narrow face and beaked nose

Symptoms There are three main features of Kearns Sayre syndrome: It starts before age 20 Paralysis of certain eye muscles (external ophthalmoplegia) that gets worse over time Degeneration of the retina, the part of the eye responsible for sight Because mitochondria are found in cells throughout the body, Kearns Sayre syndrome may affect many different organs and body systems.

Some conditions associated with Klinefelter are hypothyroidism, infertility, testicular cancer, and an increased risk for male breast cancer. What are some symptoms?: testosterone deficiency enlarged breasts (gynecomastia) sparse facial and body hair small hard testes inability to produce sperm (infertility) Chromosomes and Klinefelter syndrome, 47XXY: People typically have two sex chromosomes in each cell. Females have two X chromosomes, and males have one X and one Y. Males with Klinefelter syndrome most often have a single extra copy of the X chromosome, for a total of 47 chromosomes per cell; this is referred to as (47,XXY.) Some men with Klinefelter syndrome have the extra X chromosome in only some of their cells; this is called "mosaic 46,XY/47,XXY." Extra copies of the X chromosome interfere with male sexual development and testicular functioning, thus explaining some of the conditions outlined above.

What causes hyper-IgM syndrome? A flawed gene (or genes) in T cells is responsible for hyper-IgM syndrome. The faulty T cells do not give B cells a signal they need to switch from making IgM to making IgA and IgG. Most cases of hyper-IgM syndrome are linked to the X chromosome. Because boys carry only one X chromosome, unlike girls whose second X chromosome helps to protect against the disease, more boys than girls have IgM syndrome.
