Recent evidence suggests that steroid abuse among adolescents is on the rise. The 1999 Monitoring the Future study, a NIDA-funded survey of drug abuse among adolescents in middle and high schools across the United States, estimated that 2.7 percent of 8th- and 10th-graders and 2.9 percent of 12th-graders had taken anabolic steroids at least once in their lives. Vidyya is pleased to present a compilation of scientific information on anabolic steroids that will help professionals and the public recognize the risks of steroid abuse.
On 05 October 2000 Vidyya reported that one of the largest studies on the long-term health effects of silicone breast implants, found no association between breast implants and the subsequent risk of breast cancer.

For some time, Vidyya had been following reports of Rift Valley Fever in Yemen and Saudi Arabia. According to WHO, there have been at least 291 cases and 64 deaths from the disease confirmed in the vicinity of Yemen and Saudi Arabia.

support international efforts to control and prevent Rift Valley Fever (RVF) in Yemen.
