There are many possibilities. The most common factor is a family history of vein problems. Other common causes are pregnancy, hormonal changes (pregnancy or menopause), obesity and history of trauma. Interestingly, many very athletic men and women can develop vein disease. Standing for long periods of time can make problems worse probably because of the added stress placed on vein valves.

Remember that a shunt is a "foreign body" within the patient and the tubing is made from synthetic materials; therefore, malfunction could be due to one of the following:

Basically, we know all forms of stress whether physical (like surgery or motor vehicle accidents), emotional (loss of a loved one, divorce or financial change) or psychological stress can directly impact the thyroid. Other common offenders are hormone imbalances such as adrenal insufficiency, estrogen/progesterone changes, new chemicals and pollutants in our environment, and yes, last but not least, genetics (good old family history).

Pituitary tumors are common. In autopsy studies of patients who did not have known pituitary disease, as many as 26% had a small tumor (adenoma) in the gland. Molecular biology studies have shown that a change in the DNA of pituitary cells can cause unregulated growth of a particular cell type resulting in a pituitary tumor, called an adenoma. There are no known environmental causes. Very uncommonly, pituitary tumors may be inherited.

The line over malfunction is usually the result of a canopy's control line (sometimes even a D-Line) passing in front of the nose prior to inflation. This causes the canopy to open in a "Bow-Tie" shape. The result is generally and uncontrolled spin.

A pituitary tumor is a tumor that begins in the pituitary gland. Most pituitary tumors are not cancer. In fact, cancerous pituitary tumors are so rare that state and national cancer agencies keep no record of how many people get them each year. Benign (non-cancerous) pituitary tumors are also rare. About 3,000 people get them each year.

The pituitary gland is a small gland located behind the nasal sinuses and above the roof of the mouth at the base of the skull. It is connected to the hypothalamus, a part of the brain. Together, the two control the production of many of the important hormones in the body. The pituitary gland sits in a tight bony space and has little room to grow or expand when swollen or if there is a tumor.

CDI itself does not interfere with menstruation or fertility. However, it may be associated with these or other problems if the disease or injury that caused the DI also damages adjacent parts of the brain or pituitary where other hormones are normally produced. Head trauma is one of the things that can cause this kind of collateral damage, but it does not always do so. Therefore, each patient with CDI must be evaluated separately to determine if any of the other hormones have been affected.

The tail inversion malfunction occurs when the canopy's trailing edge flips under during deployment. It usually then becomes entangled with a steering line. Tail inversions are the product of a rapid disreefing of the tail. They are very common on slider down/removed deployments and very rare when using a slider. They almost always clear by themselves and usually go unnoticed. The evidence of their ocurance can be found when inspectiong your canopy.

The electronics are 100% solid state and will give years of trouble-free service. Klima-Gro carries a full one year parts and labor guarantee against defects in manufacture, and should anything ever malfunction, the control panel is modular, removable by four screws, so there is no need to send in the entire greenhouse. Just remove these screws, unplug the component connections, send to manufacturer and it should be back within one week.

Pituitary tumors that affect hormones may cause a variety of symptoms, which are related to high hormone levels and production. These symptoms will be different in children than in adults. Growth hormone-secreting adenomas in children may cause: Other more rare kinds of pituitary tumors cause other symptoms. It is important for anyone who is experiencing any unusual symptoms to see their doctor.

In most cases, pituitary tumors are treated by surgery, radiation therapy, or by using drugs that block the tumor's ability to produce hormones. Surgery: The goal of surgery is to remove the entire tumor from the pituitary gland. This is possible with most microadenomas but may be less likely with macroadenomas. Sometimes the entire pituitary gland will have to be removed. Medications can provide the hormones that the pituitary gland used to produce.
