The Food and Drug Administration on Thursday cautioned consumers against using quinine for leg cramps, warning that the drug could cause severe side effects, including death. Quinine, sold in this country under the brand name Qualaquin, is approved for treatment of uncomplicated malaria, but has a long history of use as a remedy for leg cramps, especially at night. In many countries, it is sold over the counter. Studies have shown that it can reduce the incidence of cramps by one-third to one-half but that as many as one in every 25 users can suffer serious side effects.

Deborah Raffin, a film actress, veteran of television miniseries and entrepreneur whose company, Dove Books-on-Tape, became a major force in the audio book industry, died Wednesday of leukemia at the Ronald Reagan UCLA Medical Center. She was 59. She was diagnosed with the blood cancer about a year ago, said her brother, William. The blond, California-born actress first came to attention in the mid-1970s playing "pretty girl" roles in movies such as "Forty Carats" with Liv Ullman and "Once Is Not Enough," based on the salacious novel by Jacqueline Susann.

BEIJING - Zhu Ruifeng fancies himself a Chinese version of WikiLeaks founder Julian Assange, a citizen journalist who is plying his trade online. In 2006, he started the People's Supervision website, which breaks stories about official corruption in China. He has had a couple of scoops - one about the widespread use of expired vaccines and others about crooked party apparatchiks - but nothing that's gotten the reaction of a sexually explicit 36-second video released last week. The video shows a paunchy Communist Party official in flagrante delicto with an 18-year-old woman in Chongqing.

Mitt Romney drew a warm reception from the National Rifle Assn. on Friday as he attacked President Obama for “employing every imaginable ruse and ploy” to restrict gun rights, which Romney pledged not to do if elected in November. Although gun control groups have complained that Obama has done little to support their cause, Romney took a page from the NRA leadership, which has been saying that the president is waiting for a second term to crack down on firearms. He warned that Obama would “remake” the Supreme Court in a second term, threatening constitutional freedoms.

Los Angeles Mayor Antonio Villaraigosa spoke publicly for the first time Monday about the breakup of his 20-year marriage, saying he was responsible for the split even as he refused to talk about what caused it. In a somber meeting with reporters at City Hall, Villaraigosa declined to answer questions about whether the break with his wife, Corina, was triggered by another romantic relationship.

The Berlin Patient, the only person considered cured of HIV, may soon have some company. Researchers at the International AIDS Conference in Washington, D.C., made presentations Thursday on two HIV-positive men from Boston who developed lymphoma. In both cases, their treatment included a bone marrow transplant, which results in a new immune system. The bone marrow donors did not have HIV. The patients were conditioned for their transplants with a reduced-intensity protocol that allowed them to maintain enough strength to continue taking antiretroviral drugs to keep their HIV in check.

INDIANAPOLIS -- Danica Patrick's return to the Indianapolis Motor Speedway in a stock car ended in a hard crash less than halfway through Saturday's Indiana 250. Patrick, the former IndyCar driver who now races in NASCAR's second-tier Nationwide Series, was running about 20th when the top five race leaders made pit stops. Patrick remained on the track and was running behind Reed Sorenson. As the two entered Turn 1 on lap 39 of the 100-lap race, Patrick's No. 7 Chevrolet tapped the back of Sorenson's No. 98 Ford, sending Sorenson into a spin.

A heart surgeon at Cedars-Sinai Medical Center unwittingly infected five patients during valve replacement surgeries earlier this year, causing four of the patients to need a second operation. The infections occurred after tiny tears in the latex surgical gloves routinely worn by the doctor allowed bacteria from a skin inflammation on his hand to pass into the patients' hearts, according to the hospital. The patients survived the second operation and are still recovering, hospital officials said.

BEIJING -- A man with a knife slashed 22 children and one adult outside an elementary school in Henan province Friday morning, China's worst such incident in more than a year. The attack was reminiscent of a spate of knife attacks on schoolchildren that took place across China in 2010. In most cases, the attackers were unemployed middle-aged men, leading to speculation that the assaults stemmed from economic and social discontent. Friday's attack occurred at about 7:40 a.m. as children were arriving outside the gate of Chenpeng Village's Wanquan Elementary School.

Asthma sufferers have long relied on inhalers for relief from wheezing or coughing attacks. But as of Dec. 31, Primatene Mist -- the only available over-the-counter asthma inhaler -- was taken off shelves because of its adverse effect on the environment. Other inhalers are available, but these require a doctor's prescription. Some people with asthma aren't happy about the change, but lung doctors and asthma specialists agree that Primatene Mist wasn't the best option for patients anyway.
