106 Major League Baseball Players Granted Exemptions for ADHD Drugs

Almost 8 percent of all major league baseball players used drugs to treat attention deficit hyperactivity disorder (ADHD) during the 2008 season, almost twice the percentage of the general population.

The drugs -- usually stimulants -- to treat ADHD are among those banned for general use in the major leagues, according to the Associated Press. The 106 exemptions -- 7.86 percent of all major league players -- are actually three more than granted during the 2007 season, the wire service reports.

The National Institute of Mental health estimates that 3-to-5 percent of U.S. children have ADHD.

A major league spokesman told the A.P. that making that sort of comparison might not be a fair one. "We are far younger than the general population," Rob Manfred, baseball's executive vice president of labor relations, is quoted as saying, "and we have far better access to medical care than the general population."

But Dr. Gary Wadler, chairman of the committee that creates a list of banned drugs for sports organizations, told the wire service he was concerned about the percentage exemptions for ADHD drugs in major league baseball.

"I've been in private practice for a lot of years," W#adler told the A.P.. "I can count on one hand the number of individuals that have ADD. To say that (7.86 percent) of major league baseball players have attention deficit disorder is crying out for an explanation."


CDC Director Gerberding Submits Resignation

The first woman to head the U.S. Centers for Disease Control and Prevention has submitted her resignation, the Associated Press has learned.

The wire service reports it obtained a copy of Dr. Julie Gerberding's resignation e-mail to employees at the Department of Health and Human Services, the CDC's parent agency. William Gimson, the CDC's chief operating officer, will be interim director after Barack Obama becomes president, the AP reports, but no permanent successor has been announced.

Gerberding became CDC director in July 2002, after joining the agency in 1998 as an infectious disease specialist. There had been some speculation she would remain as the agency's director, the AP reports, but her resignation, effective Jan. 20, was accepted by the Obama transition team.

The CDC investigates disease outbreaks and is the official government record-keeper of U.S. health statistics.

Gerberding has been considered an effective communicator, the wire service reports, but a number of problems occurred during her time in office.

These included a shortage of flu vaccine in 2003 and 2004; the departure of a number of CDC scientists during a reorganization she ordered; the CDC's response time to complaints about formaldehyde levels in trailers being provided to Hurricane Katrina survivors, and what was explained as a "computer glitch" when Gerberding reported that obesity had surpassed smoking as the top cause of death in the United States.


FDA Delays Decision on Gardasil Approval for Older Women

The U.S. Food and Drug Administration has asked drug maker Merck & Co. for more information before it decides whether to expand approval for Gardasil, a human papillomavirus vaccine, Merck said Friday.

Gardasil is currently approved for females ages 9 to 26. Merck has asked the FDA to widen approval for its use in women aged 27 to 45, the Associated Press reported. The drug is designed to guard against HPV, which is responsible for most cases of cervical cancer.

The FDA wants additional data from an ongoing 48-month study of Gardasil, the wire service said. The agency's action does not affect currently approved uses or Merck's application to approve the drug for use in males ages 9 to 26.

The vaccine costs about $360 for the three required doses, and some experts have said it's not cost-effective for older women, Dow Jones news service reported. A Harvard study funded by the U.S. government and published last year, found the vaccine was cost-effective for girls, but not for females in their 20s, the AP said.


Consumers Union Urges Expanded Testing of Infant Formula

Consumers Union urged the U.S. Food and Drug Administration on Friday to expand testing of infant formula for melamine and related compounds, and to recall all contaminated products.

The request came after the FDA published two new reports of contamination on its Web site over the holidays, doubling the number cases previously reported last November. The FDA deemed melamine levels in the new cases extremely minute and safe for babies. Traces of the industrial chemical melamine and a byproduct, cyanuric acid, have now been found in four of 89 containers of infant formula made in the United States, the Associated Press reported.

The two new cases involved containers of Mead Johnson's Enfamil LIPIL with Iron that had traces of cyanuric acid, a weak acid used as a chlorine stabilizer in swimming pools. Previous tests had found traces of melamine in a can of milk-based liquid Nestle Good Start Supreme Infant Formula with Iron. A third major formula maker, Abbott Laboratories, whose brands include Similac, told the AP in November that in-house tests had detected traces of melamine in its formula, but far below levels the FDA found in the other formulas.

Consumers Union called the FDA risk assessment from November 2008 "flawed," saying it ignored important scientific data. The FDA now says that up to one part per million of melamine in formula is safe. Levels in the new cases were well below that standard, but an agency risk assessment issued as recently as October 2008 had said that no amount of melamine in formula could be considered safe.

Melamine-tainted formula has sickened tens of thousands of children in China, killing at least six. The melamine was apparently added to milk powder by manufacturers to make their watered-down formulas appear more nutritious. The FDA has said that domestic supplies are safe, however, because U.S. formula makers do not obtain ingredients for their products from China.

Abbott Laboratories, Nestle and Mead Johnson make more than 90 percent of the infant formula produced in the United States, the AP said.
