If lung cancer and heart disease aren’t bad enough, cigarette smokers are also at higher risk for developing, among other things, pancreatic cancer. Now, researchers at the Kimmel Cancer Center at Jefferson in Philadelphia have preliminary evidence indicating one possible reason why. Data being presented April 13, 2008 during the Annual Meeting of the American Association for Cancer Research shows that they have found that nicotine in cigarettes increases the production of a protein that is known to promote cancer cell survival, invasion and spread.

The treatment of uterine fibroids with 3T MR-guided focused ultrasound (MRgFUS) is safe, non-invasive and effective, according to a recent study conducted by researchers at Weill Cornell Medical College in New York, NY.
“Approximately 25% of women in the United States have clinically symptomatic fibroids, and treatment has most commonly been surgical with hysterectomy or myomectomy. However, in the past decade, new options have been developed in radiology, includingnon-invasive MR-guided focused ultrasound (MRgFUS) and minimally invasive uterine artery embolization (UAE) to treat these patients,” said Elizabeth K. Arleo, MD, lead author of the study along with Robert J. Min, MD, MBA, chairman of radiology at Weill Cornell Medical College.

Heart surgeons at Washington University School of Medicine in St. Louis report that by adding a simple 10-20 second step to an operative procedure they achieved a significant improvement in the outcome for the surgical treatment of atrial fibrillation (AF).
Reporting in the April issue of the Journal of Thoracic and Cardiovascular Surgery, the surgeons describe an enhancement to the Cox-Maze procedure, a surgical procedure that redirects wayward electrical impulses causing AF by creating precisely placed scars, or ablations, in the heart muscle. The Cox-Maze procedure is highly effective, offering the best long-term cure rate for persistent atrial fibrillation.

Triple-negative breast cancers are a heterogeneous group and may not always be associated with lymph node spread, a new study shows.

The study of 145 triple negative breast cancers (i.e, cancer which is estrogen receptor-negative, progesterone receptor-negative and HER2-negative) in 128 women found that about 23% were moderate or low-grade lesions, said Cecilia Mercado, MD, of New York University School of Medicine, and an author of the study.

Sonoenteroclysis, a new sonographic method in evaluating and diagnosing small bowel disorders is an effective alternative to the usual method of barium enteroclysis, according to a recent study conducted by researchers at the Postgraduate Institute of Medical Education and Research in Chandigarh, India. Sonoenteroclysis is a new way of doing transabdominal ultrasound. Patients are given fluid through the nasojejunal tube in order to alleviate gas in the bowel.

A breast cancer patient’s age alone should not determine whether or not she receives standard breast-conservation treatments, including a lumpectomy and radiation therapy; however, if additional health problems (comorbidities) are present, treatments should be individualized based on age and the type of comorbidities, according to a study in the April 1 edition of the International Journal for Radiation Oncology Biology Physics, the official journal of the American Society for Therapeutic Radiology and Oncology.

Carotid artery stenting is an effective option for high risk patients who are not eligible for surgery, according to a long-term study published in this week’s New England Journal of Medicine. Carotid artery disease, which involves clogging of the arteries in the neck that provide blood to the brain, is a significant risk factor for stroke, making these study results important for the estimated 200,000 Americans each year who would otherwise not be candidates for the treatment.

If you’re constantly reaching for antacids to control your heartburn, you may have a more serious problem called reflux disease. Some 25 million Americans have it* and now they have a new option to treat it. Using a newly-approved device for the first time in the U.S., doctors have performed surgery to fix reflux problems without making a single incision.

Doctors in India successfully operate on a two-year-old girl born with four arms, four legs and extra internal organs. A team of around 30 medics removed what amounted to Lakshmi Tatma’s headless identical twin sister who was joined at the pelvis and who did not develop and separate properly in the womb.
