Key indicator for successful treatment of infertile couples

“As a woman approaches menopause, her level of follicle stimulating hormone (FSH) rises,” explained Goldman. “A higher FSH level is a key indicator that the woman may not be as fertile as necessary to conceive using certain common methods of infertility treatment.” The study determined if FSH and estrogen at the upper limits of normal, as measured on day three of the menstrual cycle, could predict treatment success as measured in live birth rates…

Bone cancer surgical team sees success in new application of surgical aid

The Spider Limb Positioner is a pneumatic arm with three fully articulating joints that can be infinitely adjusted in relation to the operating table where it is mounted. The positioner mobilizes patients’ limbs so surgeons don’t have to, thereby freeing up both their hands to operate. …

Colonoscopy withdrawal times linked to polyp detection rates

"There has been controversy over whether longer withdrawal times could lead to detection of increased numbers of polyps of various types," said Lynn F. Butterly, MD, director of Colorectal Cancer Screening at Dartmouth-Hitchcock Medical Center and NCCC, and associate professor of Medicine at the Geisel School of Medicine at Dartmouth. "Since the rate of discovery of polyps is a critical quality measure for colonoscopy, examining whether or not there is an association between withdrawal time and finding more polyps may contribute evidence leading to improved quality in screening through colonoscopy." During a colonoscopy, a lighted tube (colonoscope) is passed through the colon to find and remove polyps…

Lung cancer screening: CT scans more effective than X-rays

Screening for lung cancer using low-dose computed tomography (CT scans) rather than chest X-rays may be a more effective way of detecting the disease, Medscape Today reported. Researchers hope that these results, collected as part of the National Lung Screening Trial, will provide more detailed information about the benefits of various types of lung cancer screening available to patients and physicians. During the study, 26,309 participants received low-dose CT scans, and 26,035 participants underwent chest radiography to detect for signs of lung cancer. Among those who received CT scans, a total of 7,191 participants (27.3 percent) had a positive screening result, compared to 2,387 (9.2 percent) in the chest X-ray group. Overall, lung cancer was diagnosed in 292 participants (1.1 percent) in the CT group compared with 190 (0.7 percent) in the radiography group. Previously, experts had been concerned that the high level of false-positive screenings that occur during CT scans would lead to undue stress, unnecessary testing and high medical bills for patients, Medscape Today reported. However, the new report reveals that the majority of patients who had a positive result after their CT scan only underwent one additional diagnostic test. “In many of the previous analyses people have assumed that there would be three or four or five additional diagnostic tests for every positive screen, and this has ramifications for the cost effectiveness of screening,” study author Dr. William C. Black, professor of radiology at the Dartmouth-Hitchcock Medical Center in Lebanon, N.H., told Medscape Today. Black is hopeful that these results will provide a good frame of reference for other lung cancer screening programs. “If patients and their clinicians are trying to decide whether or not to get screened, they can always refer to these results. They will let patients know what they can expect, what are the likely outcomes, not just in terms of dying of lung cancer, which is only going to happen to a small percentage of people who get screened, but also in terms of the false positives and what happens afterwards,” Dr. Black told Medscape Today. People eligible for lung cancer screening include men and women, ages 55 to 74, who have a 30-pack-per year history of smoking, those who have quit smoking in the last 15 years and those who are medically fit for surgery.
