Disease-causing genetic mutations in sperm increase with age
September 25th 2003Older men's sperm is more likely to contain disease-causing genetic mutations, suggests an analysis of sperm from men of various ages by scientists from the McKusick-Nathans Institute for Genetic Medicine at Johns Hopkins University, Baltimore.
AMA applauds Texas medical liability victory
September 25th 2003Texas patients and physicians scored a major victory when voters approved Proposition 12, a constitutional amendment that authorizes the legislature to determine limitations on non-economic damages in medical liability cases. The vote ratifies the state's recently enacted medical liability reforms.
Surgical mishaps more common in physician offices than ASCs
September 25th 2003Patients undergoing surgery in ambulatory surgery centers are safer than those who undergo procedures in doctors' offices, although the relative risk of death or injury is low in both types of facilities, a new Florida study indicates.
Prostate cancer deaths on the decline nationwide
September 10th 2003Progress has been shown in the death rates from prostate cancer and the other three leading cancers-lung, breast, and colorectal. Deaths from prostate cancer have fallen 4.0% during the 5-year period from 1996 to 2000. Bladder cancer decreased by 0.4% over the same period.
Combination treatment boosts bladder cancer survival rate
September 10th 2003Patients with locally advanced bladder cancer have more than a fighting chance for survival with neoadjuvant chemotherapy, which has been found to provide a longer life in patients compared with the standard treatment of surgery alone, according to an 11-year study published in the New England Journal of Medicine (2003; 349:859-66).
SNPing Away at Prostate Cancer: Susceptibility and Pharmacogenetics
September 1st 2003Increasing knowledge of the ways in which we differ from each other genetically has the potential to change the way medicine is practiced in the not too distant future.88 One of the most common forms of human genetic diversity is the single nucleotide polymorphism (SNP), a single base-pair position in genomic DNA at which different sequence alternatives (alleles) exist in normal individuals.
Molecular Mechanisms in Prostatic Carcinogenesis
September 1st 2003In the developed world, environmental factors-particularly diet-seem to play a prominent role in the development of prostate cancer.27 Research into the molecular pathogenesis of prostate cancer may help us assess why prostate cells are particularly vulnerable to such environmental effects and to determine what somatic genome mutations are involved in the transformation of normal epithelium into intraepithelial neoplasia (PIN) and ultimately to invasive carcinoma (Figure 5).
Perspectives in Prostate Chemoprevention
September 1st 2003Chemoprevention is the use of natural or synthetic agents to avert the induction of, or to inhibit, delay, or suppress the progression of cancers or other diseases. Carcinogenesis is a process that occurs over a period of months to years and is under the influence of a range of genetic and environmental factors.
How drug therapy is changing the face of urology practice
September 1st 2003Urology has always been a fascinating and somewhat hybrid specialty inthe field of medicine. First and foremost, it has been a surgical specialty,requiring many years of intense surgical training to master. Many of ushave been drawn to urology because of the wide assortment of surgical proceduresand the ability to put to use the highest technological advancements inthe course of our work.
New tax relief legislation allows one property write-off
September 1st 2003The out-of-pocket expenditures needed to buy the equipment used in every practice have always been reduced or helped by our tax laws. Today, thanks to the new Jobs and Growth Tax Relief Reconciliation Act of 2003, the needed equipment may be more affordable than ever.
5-AR inhibitor reduces risk of BPH-associated events
September 1st 2003Chicago-Real-world clinical practice data provide further evidencethat treatment with a 5-alpha-reductase inhibitor significantly reducesthe risks for progression to acute urinary retention (AUR), catheterization,or surgery in men with BPH, according to a retrospective analysis from theUnited Kingdom.
Adjuvant androgen ablation plus RT reduces PCa failure
September 1st 2003Chicago-Adjuvant androgen ablation following radiation therapysignificantly reduces the risk of local and distant failure and significantlyimproves overall survival in patients with unfavorable-prognosis prostatecancer, according to 10-year results from a large cooperative group trial.
Managing prostatitis requires a multi-faceted approach
September 1st 2003Although antibiotics are commonly used to treat symptoms of chronic pelvicpain syndrome, this approach is beneficial in a relatively small subsetof patients, and urologists must consider alternative treatment modalities,including physical therapy. In this exclusive Urology Times interview, JeannettePotts, MD, discusses current research and her own views on the diagnosisand treatment of chronic prostatitis. Dr. Potts is a member of the staffat the Cleveland Clinic Glickman Urological Institute. The interview wasconducted by Philip M. Hanno, MD, of the department of urology, Universityof Pennsylvania, Philadelphia.
Lower PSA threshold may improve test's clinical value
September 1st 2003Seattle-A new study suggests that a lower PSA threshold for consideringa prostate biopsy may improve the clinical value of the widely used test.In addition, lowering the threshold for biopsy may be particularly importantfor men under the age of 60 years, according to researchers from Brighamand Women's Hospital in Boston and Washington University School of Medicinein St. Louis.
