As this issue goes to press, thousands of rescue personnel from the United States and other countries throughout the world are engaged in relief efforts in earthquake-ravaged Haiti, where the death toll exceeded 100,000.

As the U.S. waiting list for kidney transplants grows, and with it the potential for longer waiting times, so might the temptation among end-stage renal disease patients to travel abroad for a transplant.

In recent years, a number of studies purport to show that active surveillance with the potential for delayed treatment (AS-DT) is a feasible option for selected prostate cancer patients, namely those with low-risk tumors.

Research developments that have implications for nephrology and urology certainly are not limited to the meetings and journals targeting these specialties. That is why our news coverage extends to meetings that nephrologists and urologists usually do not attend and journals they usually do not read.

Through millions of years of evolution, nature has created a fantastic array of plant and animal species, each with specific adaptations to survive. These adaptations have resulted in an incalculable number of organic compounds unique to each living thing.

Medicare reductions in payments for commonly performed procedures have forced physicians to change their practices so that they can pay for ever-increasing office expenses and still make a decent living.

The mechanisms underlying the placebo effect are not fully understood, but it is clear that if subjects believe they are taking something that could help them, they can experience improvement in signs and symptoms, even by objective measures.

For centuries, human beings have spread diseases long distances through their travels.
