Syncope

Fainting is a temporary loss of consciousness. If you're about to faint, you'll feel dizzy, lightheaded, or nauseous. Your field of vision may white out or black out. Your skin may be cold and clammy. You lose muscle control at the same time, and may fall down. Fainting usually happens when your blood pressure drops suddenly, causing a decrease in blood flow to your brain. It is more common in older people. Some causes of fainting include. -Heat or dehydration . -Emotional distress . -Standing up too quickly . -Certain medicines . -Drop in blood sugar . -Heart problems . When someone faints, make sure that the airway is clear and check for breathing. The person should stay lying down for 10-15 minutes. Most people recover completely. Fainting is usually nothing to worry about, but it can sometimes be a sign of a serious problem. If you faint, it's important to see your health care provider and find out why it happened. .  [from MedlinePlus]

Multiple endocrine neoplasia

An autosomal dominant inherited neoplastic syndrome characterized by the development of various endocrine neoplasms and abnormalities in various anatomic sites. There are three types recognized: type 1 (MEN 1), caused by inactivation of the tumor suppressor gene MEN-1, type 2A (MEN 2A), caused by mutation of the RET gene, and type 2B (MEN 2B) also caused by mutation of the RET gene. Patients with MEN 1 may develop hyperparathyroidism and parathyroid gland adenomas, pituitary gland adenomas, pancreatic islet cell neoplasms, and carcinoid tumors. Patients with MEN 2A develop medullary thyroid carcinomas, and may also develop pheochromocytomas and parathyroid gland hyperplasia.
