Autonomous Tumor Localization and Extraction: Palpation, Incision, Debridement and Adhesive Closure with the da Vinci Research Kit. This video demonstrates a successful trial of the entire five-step procedure where human input is required only at four points to change tools. We also show failure modes of the current autonomous system and we are working on experiments to characterize the reliability of each step and on incorporating computer vision and new probing algorithms to improve robustness.
Renal transplantation is the treatment of choice for a minority of patients with end-stage renal disease (ESRD). Most adult patients with ESRD are never referred for evaluation for transplantation, and have a 70% 5-year mortality on dialysis. Marked improvements in early graft survival and long-term graft function have made kidney transplantation a more cost-effective alternative to dialysis. In the United States, over 375,000 kidney transplants have been performed, and in 2012, 191,400 patients were alive and with a functioning transplanted kidney; currently, more than 101,000 patients are waiting for kidney transplants.[1, 2] Before the advent of immunosuppression, renal transplantation was limited to identical twins and was not applicable to the vast majority of patients with ESRD. The introduction of combined azathioprine-steroid therapy in 1963 produced encouraging results and became the mainstay of immunosuppression. Although this therapy improved the results of transplantation, acute rejection and complications associated with steroid therapy persisted. The introduction of cyclosporine in 1983 significantly improved the outcomes of all solid-organ transplants by reducing the risk of rejection. Further innovations, including anti–T cell antibodies (both monoclonal and polyclonal preparations), as well as other maintenance immunosuppressants (eg, tacrolimus, mycophenolate, sirolimus), have made a significant impact on both patient and graft survival. Currently, 1-year patient and graft survival rates exceed 90% in most transplant centers.

Specific treatment for menorrhagia is based on a number of factors, including: Your overall health and medical history The cause and severity of the condition Your tolerance for specific medications, procedures or therapies The likelihood that your periods will become less heavy soon Your future childbearing plans Effects of the condition on your lifestyle Your opinion or personal preference Drug therapy for menorrhagia may include: Iron supplements. If you also have anemia, your doctor may recommend that you take iron supplements regularly. If your iron levels are low but you're not yet anemic, you may be started on iron supplements rather than waiting until you become anemic. Nonsteroidal anti-inflammatory drugs (NSAIDs). NSAIDs, such as ibuprofen (Advil, Motrin IB, others) or naproxen (Aleve), help reduce menstrual blood loss. NSAIDs have the added benefit of relieving painful menstrual cramps (dysmenorrhea). Tranexamic acid. Tranexamic acid (Lysteda) helps reduce menstrual blood loss and only needs to be taken at the time of the bleeding. Oral contraceptives. Aside from providing birth control, oral contraceptives can help regulate menstrual cycles and reduce episodes of excessive or prolonged menstrual bleeding. Oral progesterone. When taken for 10 or more days of each menstrual cycle, the hormone progesterone can help correct hormone imbalance and reduce menorrhagia. The hormonal IUD (Mirena). This intrauterine device releases a type of progestin called levonorgestrel, which makes the uterine lining thin and decreases menstrual blood flow and cramping. If you have menorrhagia from taking hormone medication, you and your doctor may be able to treat the condition by changing or stopping your medication.
Cluster headaches, occur in cyclical patterns or clusters, are one of the most painful types of headache. A cluster headache commonly awakens you in the middle of the night with intense pain in or around one eye on one side of your head. Bouts of frequent attacks, known as cluster periods, can last from weeks to months, usually followed by remission periods when the headaches stop. During remission, no headaches occur for months and sometimes even years. Fortunately, cluster headache is rare and not life-threatening. Treatments can make cluster headache attacks shorter and less severe. In addition, medications can reduce the number of cluster headaches.
You may have a lot of questions about epilepsy. We will help you understand the basics, answer the most common questions, and help you find resources and other information you may need. However, information alone won’t help you manage your epilepsy and find a way to cope with the effects on your daily life. You’ll need to learn how to use the information and make it work for you.
Surfactant. Surfactants are compounds that lower the surface tension (or interfacial tension) between two liquids or between a liquid and a solid. Surfactants may act as detergents, wetting agents, emulsifiers, foaming agents, and dispersants.
Primary aldosteronism, also known as primary hyperaldosteronism or Conn's syndrome, is excess production of the hormone aldosterone by the adrenal glands resulting in low renin levels. Often it produces few symptoms. Most people have high blood pressure which may cause poor vision or headaches.
Smoke inhalation is the leading cause of death due to fires. It produces injury through several mechanisms, including thermal injury to the upper airway, irritation or chemical injury to the airways from soot, asphyxiation, and toxicity from carbon monoxide (CO) and other gases such as cyanide.
