In a small but promising Phase II clinical trial of breast cancer treatment, cryoablation killed 25 early-stage tumors in 13 women. The tumors ranged in size from .5 cm (very small) to 5.8 cm (very large), with an average size of 1.7cm. Patients were first given a local anesthesia with mild sedation before physicians used ultrasound with or without computed tomography (CT) imaging to guide needle-like probes to deliver very low temperature gas to the tumor site. The ultra-cold gas forms a ball of ice around the probe tip, then expands and destroys surrounding tumor cells. A harmless saline solution was first injected into the chest wall and skin of the breast to protect the tissue surrounding the tumor from the freezing effects. Patients experienced very little pain and most healed completely within six months with no complications and with little or no scarring. The cryotherapy margins of each participant were biopsied immediately after the procedures, and all were negative, with no evidence of cancerous tissue. All 13 patients were without recurrence at an average of 18 months and up to five years following the procedure. These results are promising, but larger studies with lengthier follow-up are needed to determine whether cryotherapy as effective as lumpectomy. A study involving cryoablation of mouse tumors at the University of Michigan Comprehensive Cancer Center found that the freezing procedure also works like a vaccine, boosting the immune system to reduce the likelihood of recurrence. Just how quickly the tumor was frozen made a difference: a 30-second freeze killed tumors and also boosted the immune system, inhibiting metastases to the lungs. A slower freezing lasting several minutes destroyed tumors just as effectively, but actually suppressed the immune system, resulting in greater metastases to the lungs.

Pain in the affected bone is the most common complaint of patients with bone cancer. At first, the pain is not constant. It may be worse at night or when the bone is used (for example, leg pain when walking). As the cancer grows, the pain will be there all the time. The pain increases with activity and the person might limp if a leg is involved.

Cerebral palsy refers to brain damage that occurs before a child is five years old. Therefore, adults cannot develop cerebral palsy. However, cerebral palsy does not get better or worse with age, so when a child has the condition, he or she will continue to have the condition into adulthood.

How Bone Fractures Are Repaired

A broken bone must be carefully stabilized and supported until it is strong enough to handle the body's weight and movement. Until the last century, physicians relied on casts and splints to support and stabilize the bone from outside the body. The advent of sterile surgical procedures reduced the risk of infection, allowing doctors to internally set and stabilize fractured bones. During a surgical procedure to set a fracture, the bone fragments are first repositioned (reduced) into their normal alignment. They are held together with special implants, such as plates, screws, nails and wires. Internal fixation allows shorter hospital stays, enables patients to return to function earlier, and reduces the incidence of nonunion (improper healing) and malunion (healing in improper position) of broken bones. The implants used for internal fixation are made from stainless steel and titanium, which are durable and strong. If a joint is to be replaced, rather than fixed, these implants can also be made of cobalt and chrome. Implants are compatible with the body and rarely cause an allergic reaction.

Pulmonary fibrosis is a condition in which the tissue deep in your lungs becomes scarred over time. This tissue gets thick and stiff. That makes it hard for you to catch your breath, and your blood may not get enough oxygen. Causes of pulmonary fibrosis include environmental pollutants, some medicines, some connective tissue diseases, and interstitial lung disease. Interstitial lung disease is the name for a large group of diseases that inflame or scar the lungs. In most cases, the cause cannot be found. This is called idiopathic pulmonary fibrosis

Transvenous cardiac pacing, also called endocardial pacing, is a potentially life saving intervention used primarily to correct profound bradycardia. It can be used to treat symptomatic bradycardias that do not respond to transcutaneous pacing or to drug therapy.

Like the VenaCure EVLTยฎ procedure, which uses a laser to ablate the varicose vein, VNUS RF treatment is an alternative to more invasive leg stripping surgery. It is used primarily to treat the great saphenous veins (GSV), small saphenous vein (SSV), and other superficial veins in the legs.

Epstein-Barr is the virus that causes mononucleosis. You might know this disease better by its nickname, "mono." It's also called the "kissing disease" because of one way you can spread it to someone else. Even though Epstein-Barr virus (EBV) isn't a household name, you've probably been infected without knowing it. Lots of people carry the virus but don't get sick

The bones, ligaments and tendons that make up your shoulder joint are encased in a capsule of connective tissue. Frozen shoulder occurs when this capsule thickens and tightens around the shoulder joint, restricting its movement. Doctors aren't sure why this happens to some people, although it's more likely to occur in people who have diabetes or those who recently had to immobilize their shoulder for a long period, such as after surgery or an arm fracture.

This Video COPD, or chronic obstructive pulmonary (PULL-mun-ary) disease, is a progressive disease that makes it hard to breathe. "Progressive" means the disease gets worse over time. COPD can cause coughing that produces large amounts of mucus (a slimy substance), wheezing, shortness of breath, chest tightness, and other symptoms. Cigarette smoking is the leading cause of COPD. Most people who have COPD smoke or used to smoke. Long-term exposure to other lung irritantsโ€”such as air pollution, chemical fumes, or dustโ€”also may contribute to COPD.
