Yannas had been studying collagen, a protein found in human skin. Teaming up during the 1970s, the two made a polymer (a chemical compound made of multiple repeating units). Using collagen fibers and a long sugar molecule, they formed a porous (full of small holes) material resembling skin.
Gastric bypass, also called Roux-en-Y gastric bypass surgery, is considered a “metabolic” procedure because it changes how your body absorbs fat, calories and nutrients. This metabolic change occurs because your gastrointestinal tract is altered when your gastric bypass surgeon attaches the smaller section of your stomach directly to your small intestine. As a result, your appetite changes and you feel full faster.
Though most snakes aren't venomous, the ones with a deadly bite are so scary that many researchers think humans evolved to naturally fear the sinuous creatures. With good reason. In the video, two men milk the venom of a Russell's viper and then show what happens when one drop of that venom mixes with a glassful of human blood. It's terrifying.
On Tuesday May 29th at 3:00pm EDT, University Hospitals Case Medical Center Cleveland, Ohio, will host a live webcast to demonstrate the removal of brain tumor and epileptic focus from an awake patient using intra-operative MRI and brain mapping. See this on OR-Live.com
The patient was a middle-aged gentleman with new onset seizures. An MRI showed what appeared to be a low grade glioma near the motor strip on the right. Studies have shown that complete removal can cure the seizures, improve quality of life and survival, but this is difficult to do with conventional technology without harming the surrounding normal brain because its difficult to determine where tumor ends and normal brain begins.
Highlights of a fetal laser surgery for twin-to-twin transfusion syndrome (TTTS) will be shown from Tampa General Hospital
TTTS affects 10 to 15 percent of identical-twin pregnancies and is the result of abnormal blood exchange between identical twins through a common placenta. The larger of the twins, or recipient, is surrounded by too much amniotic fluid and in danger of heart failure as its body tries to pump the overwhelming volume of blood intended for both. The smaller, or donor twin, is encased in a shrinking amniotic sac deprived of blood. Without treatment, both will likely die.
Rubén Quintero, M.D., Medical Director of Maternal Fetal Medicine/Fetal Surgery at Tampa General Hospital and Professor and Director of the Division of Maternal Fetal Medicine, Department of Obstetrics and Gynecology, University of South Florida College of Medicine will narrate the procedure and answer e-mail questions live as taped highlights of the procedure are shown.
An estimated 900,000 knee replacements are performed in the U.S. every year, but experts say about 15% of patients aren’t totally pleased with the outcome. An advancement in technology is focused on improving those outcomes.
Acute kidney injury is common entity in medical practice. The present definition is based on a serum creatinine rise of more 0.3 mg/dl in 48 hours or less, a 50% increase from the baseline over a period of 07 days or a urine output of less than 0.5 ml/kg/hour for more than 06 hours. The main causes of acute kidney injury may be classified into pre renal, intrinsic or post renal causes. Rapid diagnosis and prompt treatment is essential to prevent mortality or morbidity. This presentation discusses in detail the causes of all three mechanisms, pre-renal, post renal and intrinsic.
Rheumatoid arthritis is a chronic inflammatory disorder that can affect more than just your joints. In some people, the condition also can damage a wide variety of body systems, including the skin, eyes, lungs, heart and blood vessels. An autoimmune disorder, rheumatoid arthritis occurs when your immune system mistakenly attacks your own body's tissues. Unlike the wear-and-tear damage of osteoarthritis, rheumatoid arthritis affects the lining of your joints, causing a painful swelling that can eventually result in bone erosion and joint deformity. The inflammation associated with rheumatoid arthritis is what can damage other parts of the body as well. While new types of medications have improved treatment options dramatically, severe rheumatoid arthritis can still cause physical disabilities.
Perineal repair after episiotomy or spontaneous obstetric laceration is one of the most common surgical procedures. Potential sequelae of obstetric perineal lacerations include chronic perineal pain,1 dyspareunia,2 and urinary and fecal incontinence.3–5 Few studies of laceration repair techniques exist to support the development of an evidence-based approach to perineal repair. This article discusses a repair method that emphasizes anatomic detail, with the expectation that an anatomically correct perineal repair may result in a better long-term functional outcome.
