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.
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.”
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).

Tongue-tie (ankyloglossia) is a condition present at birth that restricts the tongue's range of motion. With tongue-tie, an unusually short, thick or tight band of tissue (lingual frenulum) tethers the bottom of the tongue's tip to the floor of the mouth
Broca's Aphasia (expressive) When a stroke injures the frontal regions of the left hemisphere, different kinds of language problems can occur. This part of the brain is important for putting words together to form complete sentences. Injury to the left frontal area can lead to what is called Broca's aphasia.
Multiple studies demonstrate the safety of propofol in pediatric EDPS. Each has identified a drop in blood pressure and transient hypoxemia as the most frequent complications. In all of the studies in which hypotension was identified there was no evidence of poor perfusion. The hypoxemia in all of these studies quickly responded to minimal intervention with no apparent lasting complications. Although these were pediatric studies, the results were very similar to ours in complication rates and sedation times. Our study did not demonstrate the frequency of decreased blood pressure seen in these pediatric studies but had similar hypoxemia rates.
If your knee is severely damaged by arthritis or injury, it may be hard for you to perform simple activities, such as walking or climbing stairs. You may even begin to feel pain while you are sitting or lying down. If nonsurgical treatments like medications and using walking supports are no longer helpful, you may want to consider total knee replacement surgery. Joint replacement surgery is a safe and effective procedure to relieve pain, correct leg deformity, and help you resume normal activities. Knee replacement surgery was first performed in 1968. Since then, improvements in surgical materials and techniques have greatly increased its effectiveness. Total knee replacements are one of the most successful procedures in all of medicine. According to the Agency for Healthcare Research and Quality, more than 600,000 knee replacements are performed each year in the United States. Whether you have just begun exploring treatment options or have already decided to have total knee replacement surgery, this article will help you understand more about this valuable procedure.
Some common signs of spinal tumors may include the following: Pain (back and/or neck pain, arm and/or leg pain) Muscle weakness or numbness in the arms or legs. Difficulty walking. General loss of sensation. Difficulty with urination (incontinence) Change in bowel habits (retention) Paralysis to varying degrees.
This minimally invasive surgical procedure repairs the valve without removing the old, damaged valve. Instead, it wedges a replacement valve into the aortic valve’s place. The surgery may be called a transcatheter aortic valve replacement (TAVR) or transcatheter aortic valve implantation (TAVI). Valve-within-valve — How does it work? Somewhat similar to a stent placed in an artery, the TAVR approach delivers a fully collapsible replacement valve to the valve site through a catheter. Once the new valve is expanded, it pushes the old valve leaflets out of the way and the tissue in the replacement valve takes over the job of regulating blood flow.
