Aortic valve replacement is a procedure in which a patient's failing aortic valve is replaced with an artificial heart valve. The aortic valve can be affected by a range of diseases; the valve can either become leaky (aortic insufficiency / regurgitation) or partially blocked (aortic stenosis).
Minimally invasive surgery has been shown to be feasible and safe in pediatric patients since 1975 when laparoscopic surgery was first used to treat a small bowel obstruction. Laparoscopy is an option for surgical repair of inguinal hernias in addition to the traditional open approach.
This video demonstrates how bronchoscopy and vocal cord mass injections can be performed under endoscopic guidance in a patient without any sedation. Only topical and local anesthesia is used for patient comfort.
Your body needs bile, but if it has too much cholesterol in it, that makes gallstones more likely. It can also happen if your gallbladder can't empty properly. Pigment stones are more common in people with certain medical conditions, such as cirrhosis (a liver disease) or blood diseases such as sickle cell anemia.
Polycythemia vera (pol-e-sigh-THEE-me-uh VEER-uh) is a slow-growing type of blood cancer in which your bone marrow makes too many red blood cells. Polycythemia vera may also result in production of too many of the other types of blood cells — white blood cells and platelets. These excess cells thicken your blood and cause complications, such as such as a risk of blood clots or bleeding. Polycythemia vera isn't common. It usually develops slowly, and you may have it for years without noticing signs or symptoms. Often, polycythemia vera is found during a blood test done for some other reason. Without treatment, polycythemia vera can be life-threatening. However, with proper medical care, many people experience few problems related to this disease. Over time, there's a risk of progressing to more-serious blood cancers, such as myelofibrosis or acute leukemia.
Angina results from a reduction in the oxygen supply/demand ratio. Therefore, in order to alleviate the pain, it is necessary to improve this ratio. This can be done either by increasing blood flow (which increases oxygen delivery or supply), or by decreasing oxygen demand (i.e., by decreasing myocardial oxygen consumption).
Cerebral palsy is a disorder of movement, muscle tone or posture that is caused by damage that occurs to the immature, developing brain, most often before birth. Signs and symptoms appear during infancy or preschool years. In general, cerebral palsy causes impaired movement associated with abnormal reflexes, floppiness or rigidity of the limbs and trunk, abnormal posture, involuntary movements, unsteady walking, or some combination of these. People with cerebral palsy may have problems swallowing and commonly have eye muscle imbalance, in which the eyes don't focus on the same object. People with cerebral palsy also may suffer reduced range of motion at various joints of their bodies due to muscle stiffness. Cerebral palsy's effect on functional abilities varies greatly. Some affected people can walk while others can't. Some people show normal or near-normal intellectual capacity, but others may have intellectual disabilities. Epilepsy, blindness or deafness also may be present.
Fillings are a way for dentists to restore a partially decayed tooth. While many people fear the dentist, this procedure is typically quick, effective, and inexpensive. Without fillings, cavities can rapidly worsen. Seeing a dentist regularly can help you to monitor the condition of your teeth and plan for corrective procedures. According to the National Institute of Dental and Craniofacial Research, nearly 93 percent of adults between the ages of 20 and 64 have cavities, and at least 29 percent have decay that is untreated. Dentists can quickly identify tooth decay and then come up with a plan of action that involves filling teeth and restoring adverse conditions. You can do your part by sticking to a solid at-home oral hygiene routine. By simply brushing twice a day with a fluoride-treated toothpaste and flossing regularly, you can prevent the build up of bacteria-rich plaque and eliminate cavity-causing conditions.
Most scoliosis surgeons agree that children who have very severe curves (45-50° and higher) will need surgery to lessen the curve and prevent it from getting worse. The operation for scoliosis is a spinal fusion. The basic idea is to realign and fuse together the curved vertebrae so that they heal into a single, solid bone. With the tools and technology available today, scoliosis surgeons are able to improve curves significantly.
