Detailed Information on Multiple Endocrine Neoplasia
Juliet Cohen asked:
Multiple endocrine neoplasia (MEN) syndromes influence the thyroid and other endocrine glands that produce hormones in the body. Hormones are chemical messengers that travel through the bloodstream and regulate the role of cells and tissues throughout the body. Multiple endocrine neoplasia involves tumors in at least two endocrine glands; tumors can also develop in other organs and tissues. These growths can be noncancerous (benign) or cancerous (malignant). There are three forms of MEN: MEN1 (Wermer’s syndrome), MEN2A (Sipple syndrome), and MEN2B (previously known as MEN3).
Multiple endocrine neoplasia syndromes can appear in infants or in people as old as age 70. Type 1 and type 2 are distinguished by the genes involved, the types of hormones made, and the characteristic signs and symptoms. Many different types of tumors are related with multiple endocrine neoplasias. Type 1 frequently involves tumors of the parathyroid gland, pituitary gland, and pancreas. Tumors in these glands lead to the overproduction of hormones. MEN I is caused by a defect in a gene called RET. Risk factors for MEN I include a family history of this disorder, a previous pituitary tumor, and a history of Zollinger-Ellison syndrome.
The most common symptom of multiple endocrine neoplasia type 1 is overactivity of the parathyroid gland (hyperparathyroidism). Hyperparathyroidism dislocates the normal balance of calcium in the blood, which can lead to kidney stones, thinning of bones, nausea and vomiting, high blood pressure (hypertension), weakness, and fatigue. The most common sign of multiple endocrine neoplasia type 2 is a form of thyroid cancer called medullary thyroid carcinoma. Some people with this disorder also develop a pheochromocytoma, which is a tumor of the adrenal glands that can cause dangerously high blood pressure.
Multiple endocrine neoplasia type 2 is separated into three subtypes: type 2A, type 2B, and familial medullary thyroid carcinoma (FMTC). These subtypes discord in their characteristic signs and symptoms and risk of exact tumors; for example, hyperparathyroidism occurs only in type 2A. No comprehensive treatment is available for genetic conditions such as MEN. MEN 2A is treated with surgery. Diazoxide can be used to inhibit release of insulin. Hormone replacement therapy is given when glands are removed or do not produce enough hormones. High dose proton pump inhibitors are required for gastrin secreting tumours.

What Does Your Endocrine System Do?
Marshall Swerman asked:
The endocrine system consists of glands that, through the secretion of hormones, regulate just about every aspect of your body in very specific ways. Almost every cell and organ of the body is regulated by the endocrine system.
The word endocrine is derived from the Greek terms “endo” meaning within and “krine” meaning to secrete or separate. The glands in the endocrine system secrete hormones within the body.
A hormone is a chemical substance produced in the body that controls and regulates the activity of certain cells or organs. These hormones are the messengers of the endocrine system, influencing such things as metabolic activity, reproduction, mood, growth and body development. It’s interesting that the word hormone is derived from the Greek “hormao” meaning “I set in motion” or “I stir up”. This is exactly what hormones do.
So, a gland secretes a hormone into the blood and that hormone circulates throughout the body. When it meets up with the organ of the body it is supposed to have an effect upon that hormone goes into the cells of that organ and produces the required effect.
The way the system is built a hormone only affects the organ it is supposed to effect. This is due to the fact that each hormone molecule has a different shape. The cells that are supposed to be controlled by that hormone “recognize” that particular shape. The part of the body which is affected by a particular hormone is called the “target organ”.
Some of the major glands of the endocrine system are:
- Pituitary gland
- Hypothalamus
- Pineal Gland
- Thyroid
- Parathyroids
- Adrenal Glands
- Reproductive Glands (including ovaries and testes)
The Pituitary Gland, although no bigger than a pea, is considered the most important part of the endocrine system. It’s often called the “master gland” because it makes hormones that control other endocrine glands. One of the essential hormones released by the pituitary is the Human Growth Hormone which stimulates the growth of bone and other body tissues and plays a role in the body’s handling of nutrients and minerals.
They Hypothalamus is the main link between the endocrine and nervous systems. One of its functions is to control the pituitary gland.
The cone-shaped Pineal Gland secretes a hormone called melatonin which is thought to regulate sleep patterns.
Thyroid hormones control the rate at which the body burns fuel.
Among other functions, the Adrenal Glands produce a hormone called epinephrine or adrenaline which control the body’s “fight or flight” mechanism by controlling blood pressure and heart rate.
The Parathyroids are attached to the thyroid. They are responsible for regulating the amount of calcium in the blood.
Reproductive Glands are the main source of sex hormones and control many of the reproductive functions of the human body.
Endocrine system or hormone problems can come about when any one of these glands produces too much or too little of its hormone. The type and extent of any hormone disorder determines the treatment.
