Surgery to replace an aortic valve is done for aortic valve stenosis and aortic valve regurgitation. During this surgery, the damaged valve is removed and replaced with an artificial valve. The valve replacement is typically an open-heart surgery.

The gradual curves of the human spine allow the body to absorb many shocks and stresses in daily life. It’s a delicate balance, though, and if part of the spine curves too much, pain and limited mobility may result.

All forms of heparin (including low-molecular-weight heparin such as enoxaparin) must be stopped immediately in patients with suspected heparin-induced thrombocytopenia (HIT) while awaiting diagnostic confirmation. Patients with HIT remain at high risk of thrombosis even after discontinuation of heparin. Therefore, an alternate, rapidly acting, non-heparin anticoagulant such as direct thrombin inhibitor (eg, argatroban, bivalirudin) must be started immediately.

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.

This syndrome was previously known as reflex sympathetic dystrophy, algodystrophy, causalgia, Sudeck atrophy, transient osteoporosis, and acute atrophy of bone. Usually occurring after an injury, CRPS presents with pain out of proportion to the injury, temperature change, edema, and abnormal skin color. Type I CRPS (90% of CRPS cases) occurs without a definable nerve lesion, while type II occurs with a definable nerve lesion. The pathogenesis is likely due to an injury causing increased sensitivity to sympathetic nerves, an abnormal response to and sensation of pain, and increased neuropeptide release causing burning pain to light touch (allodynia).

The Estech COBRA Fusion™ 150 Surgical Ablation System combines intuitive, real-time TCRF (Temperature Controlled Radiofrequency) energy control with proprietary Versapolar technology. Versapolar™ energy delivery is the first of its kind—an adaptable and effective platform that can deliver both bipolar and monopolar energy so that surgeons can easily and efficiently create reproducible transmural lesions with more flexibility, confidence and control.

Lithium, a mood stabilizer used in bipolar disorder, has a narrow therapeutic index (small difference between therapeutic and toxic levels}. This patient's gradual onset of neurologic symptoms (slurred speech, confusion, tremors, and ataxia) is consistent with chronic lithium toxicity. Therapeutic lithium levels are 0.8- 1.2 mEq/L. Serum lithium levels >1.5 mEq/L confirm toxicity, and levels ;::2 .5 mEq/L require emergency management.

The bilateral sagittal split osteotomy is an indispensable tool in the correction of dentofacial abnormalities. The technique has been in practice since the late 1800s, but did not reach widespread acceptance and use until several modifications were described in the 1960s and 1970s. Those modifications came from a desire to make the procedure safer, more reliable, and more predictable with less relapse. Those goals continue to stimulate innovation in the field today and have helped the procedure evolve to be a very dependable, consistent method of correction of many types of malocclusion. The operative surgeon should be well versed in the history, anatomy, technical aspects, and complications of the bilateral sagittal split osteotomy to fully understand the procedure and to counsel the patient.

Dr. Glenn Barnhart explains the symptoms of mitral valve regurgitation such as becoming short of breath. There are five structures of the mitral valve: annulus, leaflet tissue, chordae tendineae, papillary muscles, and left ventricle. All of these are taken into consideration when the mitral valve is leaking and not working right. There are four degrees of mitral valve regurgitation: mild, moderate, moderately severe,.

TPIAT is a procedure that lets surgeons remove the pancreas, take out islet cells, and put those islet cells into the liver.

Magnetic Resonance Imaging (MRI) "sees" inside the body by mapping the position of water molecules, which exist at different densities in different types of tissue. Watch the video above for a sample of some impressive MRI images of the human body in action.

People with serious comprehension difficulties have what is called Wernicke’s aphasia and: Often say many words that don’t make sense. May fail to realize they are saying the wrong words; for instance, they might call a fork a “gleeble.” May string together a series of meaningless words that sound like a sentence but don’t make sense. Have challenges because our dictionary of words is shelved in a similar region of the left hemisphere, near the area used for understanding words.

Dumping syndrome is a condition that can develop after surgery to remove all or part of your stomach or after surgery to bypass your stomach to help you lose weight. Also called rapid gastric emptying, dumping syndrome occurs when food, especially sugar, moves from your stomach into your small bowel too quickly. Most people with dumping syndrome develop signs and symptoms, such as abdominal cramps and diarrhea, 10 to 30 minutes after eating. Other people have symptoms one to three hours after eating, and still others have both early and late symptoms. Generally, you can help prevent dumping syndrome by changing your diet after surgery. Changes might include eating smaller meals and limiting high-sugar foods. In more-serious cases o

Dialysis and kidney transplantation are treatments for severe kidney failure, also called kidney (or renal) failure, stage 5 chronic kidney disease, and end-stage kidney (or renal) disease. There are two types of dialysis: hemodialysis and peritoneal dialysis. When the kidneys are no longer working effectively, waste products, electrolytes, and fluid build up in the blood. Dialysis takes over a portion of the function of the failing kidneys to remove the fluid and waste products. Kidney transplantation can more completely take over the function of the failing kidneys.

Simple interrupted suturing is the most basic and most important of the suturing techniques.
