Uterine fibroid embolization effective in cases where focused ultrasound failed

Uterine fibroid embolization (UFE), a minimally invasive interventional radiology treatment for uterine fibroids, provides significant relief of symptoms for women whose focused ultrasound (FUS) treatment failed, according to a study released during the Society of Interventional Radiology's 33rd Annual Scientific Meeting in Washington, D.C. Primary care physicians and gynecologists can feel confident in informing patients that a failed FUS treatment does not require subsequent gynecological surgery.

Scans spot hidden tumors in Li-Fraumeni syndrome

Researchers at Dana-Farber Cancer Institute report that full-body PET/CT scanning detected unsuspected, treatable tumors in 3 of 15 patients with Li-Fraumeni syndrome (LFS), a rare genetic cancer syndrome for which no screening tests have been recommended.

New technique improves outcome for living donor liver transplants

The University of Alberta Hospital (UAH) is one of only a few centers in Canada that perform living donor liver transplantation, a surgical procedure developed in the late 1980s that expands the organ donor pool. About 80 liver transplants are done a year in Alberta, 10 of those being living-donor.

New interventional radiology treatment shows promise for complications from bone marrow, stem cell tranplants

The standard treatment to treat graft-versus-host disease (GVHD) after bone marrow or cord blood transplant is intravenous (IV) steroids that alter the immune response; however, it is not always effective and failure results in very high mortality.

$Variants of the gene LRP5 associated with increased risk of bone fractures, low bone mineral density$

Variants of the gene LRP5 associated with increased risk of bone fractures, low bone mineral density

Results from a large study indicate that variants of the gene LRP5 are associated with a significant increase in the risk of fractures, by up to 20 percent, and lower levels of bone mineral density in the spine and hip, according to a study in the March 19 issue of JAMA, a theme issue on Genetics and Genomics.

Most women unaware of uterine fibroid embolization

A study presented at the Society of Interventional Radiology's 33rd Annual Scientific Meeting shows of 105 patients in the Atlanta metro area, only 18 percent of the women who saw a private practice gynecologist were told about uterine fibroid embolization (UFE), a minimally invasive treatment for uterine fibroids provided by interventional radiologists.

Long-term follow-up after percutaneous pulmonary radiofrequency ablation

Radiofrequency ablation (RFA) - an interventional treatment that "cooks" and kills lung cancer tumors with heat - greatly improves survival time from primary or metastatic inoperable lung tumors, according to a study released at the Society of Interventional Radiology's 33rd Annual Scientific Meeting.
