Freeze breast cancer.
Freeze breast cancer. samer kareem 1,649 Views • 3 years ago

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.

ERCP Procedure
ERCP Procedure samer kareem 2,005 Views • 3 years ago

ERCP is a procedure that enables your physician to examine the pancreatic and bile ducts. A bendable, lighted tube (endoscope) about the thickness of your index finger is placed through your mouth and into your stomach and first part of the small intestine (duodenum). In the duodenum a small opening is identified (ampulla) and a small plastic tube (cannula) is passed through the endoscope and into this opening. Dye (contrast material) is injected and X-rays are taken to study the ducts of the pancreas and liver.

Pregnancy Symptoms & Signs
Pregnancy Symptoms & Signs samer kareem 2,401 Views • 3 years ago

Every woman is different. So are her experiences of pregnancy. Not every woman has the same symptoms or even the same symptoms from one pregnancy to the next. Also, because the early symptoms of pregnancy often mimic the symptoms you might experience right before and during menstruation, you may not realize you're pregnant. What follows is a description of some of the most common early symptoms of pregnancy. You should know that these symptoms may be caused by other things besides being pregnant. So the fact that you notice some of these symptoms does not necessarily mean you are pregnant. The only way to tell for sure is with a pregnancy test.

Rhinoplasty

A nose job (technically called a rhinoplasty) is surgery on the nose to change its shape or improve its function. It can be done for medical reasons -- such as to correct breathing problems related to the nose or correct disfigurement resulting from trauma or birth defects. It can also be done for cosmetic reasons, which will change the nose's shape and appearance.

Total Heart Transplant
Total Heart Transplant samer kareem 6,788 Views • 3 years ago

Every 10 minutes, someone is added to the national transplant waiting list, and every day, 22 people on average die waiting for a match, according to the United Network for Organ Sharing. But, thanks to innovations in bioengineering, all of that could change. Conceived nearly 60 years ago, the total artificial heart (TAH) has helped sustain the sickest biventricular failure patients waiting for a transplant. While the design of the primary TAH used today has mostly remained stagnant since the ’80s, when it was first implanted in a patient, new models and clinical trials may lead to a better device and, one day, a permanent solution. “We are still many years away from that,” Dr. Nader Moazami, director of the Cardiac Transplantation and Ventricular Assist Device Therapy Program at the Cleveland Clinic, told FoxNews.com of a permanent artificial heart. “Although tremendous strides have been made, biocompatibility will always remain a challenge.”

Appendicitis is an inflammation of the appendix, a 3 1/2-inch-long tube of tissue that extends from the large intestine. No one is absolutely certain what the function of the appendix is. One thing we do know: We can live without it, without apparent consequences.

Cushing's Disease
Cushing's Disease samer kareem 5,974 Views • 3 years ago

Cushing's disease is a serious condition of an excess of the steroid hormone cortisol in the blood level caused by a pituitary tumor secreting adrenocorticotropic hormone (ACTH). ACTH is a hormone produced by the normal pituitary gland. ACTH stimulates the adrenal glands (located on top of the kidneys) to produce cortisol, commonly referred to as the stress hormone.

Cardiovascular disease (CVD) is a general term that describes a disease of the heart or blood vessels. Blood flow to the heart, brain or body can be reduced as the result of a blood clot (thrombosis), or by a build-up of fatty deposits inside an artery that cause the artery to harden and narrow (atherosclerosis).

Why Can't We Reverse Nerve Damage? samer kareem 3,407 Views • 3 years ago

Our nervous system is involved in everything our body does, from maintaining our breath to controlling our muscles. Our nerves are vital to all we do; therefore, nerve pain and damage can heavily influence our quality of life. In Discovery News' latest video, "Why Can't We Reverse Nerve Damage?" host Lissette Padilla explains the central nervous system (CNS) has certain proteins that inhibit cell regeneration, because each cell in the nervous system has a unique function on the pathway, like a circuit, and can't be replaced.

Lewy body dementia, also known as dementia with Lewy bodies, is the second most common type of progressive dementia after Alzheimer's disease dementia. Protein deposits, called Lewy bodies, develop in nerve cells in the brain regions involved in thinking, memory and movement (motor control). Lewy body dementia causes a progressive decline in mental abilities. People with Lewy body dementia may experience visual hallucinations, and changes in alertness and attention. Other effects include Parkinson's disease-like symptoms such as rigid muscles, slow movement and tremors.
