Each type of stroke and brain trauma is detected, identified and located using a simple headset and portable laptop-based console. The device's portability and speed of initial diagnosis (under a couple of minutes) make it appropriate for many uses outside of the hospital setting, including by military doctors in theater who need to assess situations quickly and efficiently in order to provide critically injured troops with treatment. http://phys.org/news220606555.html Medicine & Health Tue, 29 Mar 2011 09:30:01 EST news220606555 Pelvic arterial embolization or PAE, a minimally invasive, life-saving therapy, is a safe and effective treatment for postpartum hemorrhage, say researchers at the Society of Interventional Radiology's 36th Annual Scientific Meeting in Chicago, Ill. http://phys.org/news220606388.html Medicine & Health Tue, 29 Mar 2011 08:33:49 EST news220606388 Native Hawaiians and Pacific Islanders may be at higher risk for hemorrhagic stroke at a younger age and more likely to have diabetes compared to other ethnicities, according to a study released today that will be presented at the American Academy of Neurology's 63rd Annual Meeting in Honolulu April 9 to April 16, 2011. http://phys.org/news217009710.html Medicine & Health Tue, 15 Feb 2011 16:28:39 EST news217009710 Patients with strokes, brain tumors and spinal cord injuries are at high risk for life-threatening blood clots, but many do not receive preventive therapy, Loyola University Health System researchers report. http://phys.org/news216646857.html Medicine & Health Fri, 11 Feb 2011 12:00:02 EST news216646857 Sex in pregnancy is generally safe, with few complications, states a new primer for physicians to counsel patients wondering about sex in pregnancy, published in CMAJ (Canadian Medical Association Journal).

Those that involve intracerebral hemorrhage (bleeding in the brain) are especially deadly, and there are no effective treatments to control such bleeding. Moreover, diabetes and hyperglycemia (high blood glucose levels) are associated with increases in bleeding during hemorrhagic stroke and worse clinical outcomes. http://phys.org/news215010779.html Medicine & Health Sun, 23 Jan 2011 13:13:32 EST news215010779 A computer decision model suggests that for patients with a history of bleeding within the brain, the risk of recurrence associated with statin treatment may outweigh the benefit of the drug in preventing cardiovascular disease, according to a report posted online today that will appear in the May print issue of Archives of Neurology. http://phys.org/news213899381.html Medicine & Health Mon, 10 Jan 2011 16:29:55 EST news213899381 A research team from China investigated the minimal invasive techniques to stop the life-threatening hemorrhage from ruptured hepatic artery pseudoaneurysm after pancreaticoduodenectomy.

Sure, it's important--without it we'd all bleed to death--but it is devilishly complex, with a vocabulary only a clinical lab scientist could love. http://phys.org/news203267630.html Other Sciences Thu, 09 Sep 2010 16:50:01 EST news203267630 The data monitoring committee of the AVERROES study, seeing overwhelming evidence of the success of apixaban in the prevention of stroke in patients with atrial fibrillation who are unsuitable for the conventional treatment of warfarin, has recommended early termination of this study. The decision came after repeated review and careful consideration of all efficacy and safety data. http://phys.org/news202394487.html Medicine & Health Tue, 31 Aug 2010 05:30:01 EST news202394487 Compliance with practice guideline-recommended treatment for cirrhosis is associated with a reduction in first esophageal variceal hemorrhage (EVH; bleeding), according to a new study in Clinical Gastroenterology and Hepatology, the official journal of the American Gastroenterological Association (AGA) Institute.

Plaques are fat-laden rough spots in the otherwise smooth walls of arteries. When a plaque ruptures, blood accumulates inside of it, a process known as plaque hemorrhage. The plaque enlarges and artery-blocking clots can form. If the flow of oxygen-rich blood is restricted, a heart attack, stroke, or damage to other organs can occur. http://phys.org/news189110259.html Medicine & Health Mon, 29 Mar 2010 20:40:01 EST news189110259 A Kansas State University study aimed at alleviating intestinal damage in trauma patients digressed to an important finding that could affect medication given to the individuals. http://phys.org/news187957523.html Medicine & Health Tue, 16 Mar 2010 12:10:01 EST news187957523 Even among patients who have taken aspirin in proximity to an image-guided percutaneous biopsy, risk of major bleeding associated with the procedure is low, according to a study in the March issue of the American Journal of Roentgenology. Image-guided percutaneous biopsies are an important means of diagnosing disease in organs and other soft tissues. They involve the removal of cells or tissues for examination. http://phys.org/news185801815.html Medicine & Health Fri, 19 Feb 2010 11:37:31 EST news185801815 Peliosis hepatis (PH) is a rare pathological entity.

Only 5% to 10% of patients with duodenal diverticula suffer from clinical symptoms. Furthermore, less than 1% of patients require treatment for various complications such as perforation, hemorrhage, and biliary/pancreatic/gastrointestinal obstruction. Various treatments and operations are considered for the rare complications of diverticulum, based on the symptoms or operative field findings. http://phys.org/news170420822.html Medicine & Health Tue, 25 Aug 2009 13:40:01 EST news170420822 Patients with cirrhosis are at risk for developing portal hypertension that can lead to the formation, dilation, and rupture of esophageal varices.
