[Q]: Low doses of the drug FTY720, also called fingolimod, given  to mice once a day for three days eliminated an infection by a  virus that can cause meningitis, an inflammation of the  membranes surrounding the brain and spinal cord. The findings suggest the drug, which boosted anti-viral  immune responses in the mice, may be useful against viruses  that cause high-level, long-lasting infections in people such  as hepatitis C and HIV, the researchers said. Microbiologist and immunologist John Altman of Emory  University in Atlanta, who led the study, said the researchers  plan to assess the effects of the drug on other viruses  including the monkey version of the AIDS virus. Altman, whose findings were published in the journal  Nature, expressed cautious optimism that the drug might work  against certain chronic viral infections in people. “We think it’s crucial that we do experiments to check it  out,” Altman said in a telephone interview. The drug is generally considered to be an immunosuppressant  that works to restrain the body’s natural defenses. That could be helpful in multiple sclerosis, an autoimmune  disease in which the immune system attacks body parts as if  they were foreign invaders. But one effect of the drug seems to facilitate the immune  response, the researchers said. FTY720 among other things traps  white blood cells — key soldiers in the immune system’s fight  against infections — in the lymph nodes, Altman said. With viral infections, the lymph nodes are where the immune  response can get primed and started, Altman said. Some viruses  replicate themselves at high levels in lymph nodes, including  the human immunodeficiency virus that causes AIDS. They tested the drug against a mouse virus called  lymphocytic choriomeningitis, which causes chronic infections  by escaping immune responses. “In the absence of treatment (with FTY720) we have an  exhausted immune response. In the presence of treatment, we  regain a robust cellular immune response,” Altman said. Swiss drug maker Novartis said in June two multiple  sclerosis patients taking FTY720 in clinical trials had  problems with infections and one died, but the role of the drug  in the cases was unclear. Novartis plans at the end of 2009 to seek approval by the  European Union for FTY720 to treat MS, spokeswoman Valerie Tate  said by e-mail. The drug is currently in late-stage trials. Altman said his study was backed by the U.S. government’s  National Institutes of Health and was not funded by Novartis.

[Q]: Firefighters were battling to control more than 40 wild fires that remained ablaze across NSW, the state’s Rural Fire Service (RFS) said. There were no reports of injuries caused by the fires by mid-afternoon local time, though 45 homes were destroyed. The strong winds have blown the dangerous smoke across large parts of NSW. The RFS said the smoke was unlikely to clear for at least 24 hours, while hot, dry conditions are expected to linger for several days more - exacerbating the threat of more fires as authorities try to access the damage of blazes now extinguished. “Dust may aggravate existing heart and lung conditions and cause symptoms like eye irritation and cough,” said Richard Broome, director of environmental health, NSW Health. “Symptoms can occur for several days after dust is inhaled, so people with the chronic conditions need to be vigilant with their treatment programs.”  One of the biggest fires in recent days was recorded in Lake Cathie, 379 kilometers (235.5 miles) north of Sydney - which has destroyed more than 2,000 hectares (4,942 acres) of a national park. The fire is now contained, though the area is a prime breeding ground for koalas, stoking fears that hundreds will have been killed by the fires. “Based on our calculations, with a minimum 60% mortality rate about 350 koalas will be lost,” Sue Ashton, president of the Port Macquarie Koala Hospital told Reuters. “It’s terrible, it’s absolutely devastating. It’s a national tragedy.”  Ashton said seven rescuers on Thursday attempted to enter the worst affected areas but were advised to leave as strong winds stoked fears of the fires spreading.

[Q]: They found several creams caused skin cancer in the specially bred mice, which had been pre-treated with ultraviolet radiation. The cancers are not melanoma, the deadliest kind of skin cancer, they stressed in their report in the Journal of Investigative Dermatology, but another type called squamous cell carcinoma. Such tumours are slow growing, highly treatable and only fatal if patients fail to have them removed. Allan Conney and colleagues at Rutgers University in New Jersey said they discovered the risk while testing a theory that caffeine could prevent skin cancer. “We sort of got into this by accident,” Conney said in a telephone interview. “We wanted a safe cream that we could put the caffeine into.”   They were testing specially bred albino mice, which are prone to develop skin cancer. The mice are pre-treated with ultraviolet radiation to simulate the effects of a human who has had heavy sun exposure in the past but then stopped — something that may be happening in the population as people realize the risks of getting a tan. Conney’s team decided to test the creams first and found that all four they tested caused tumours to grow on the mice. He said he does not know why, but suspects two ingredients — mineral oil and sodium laurel sulphate. “We’d like to understand the mechanism. What is most important is to see whether these moisturizing creams are tumorigenic in people,” Conney said. He said his lab is not equipped to do this but someone should. But he added, “I don’t think that people should be scared because this is a mouse study and we don’t know whether or not it applies to humans.”   Other experts were sceptical about the study. “This is a pretty artificial situation with the mouse skin primed by a lot of UV light to develop cancer,” Karol Sikora, Medical Director of Cancer Partners U.K. in Britain, said in a statement. Dr. Jonathan Rees, an expert in dermatology at the University of Edinburgh in Scotland, said squamous cell carcinoma was not a big health worry. “Non-melanoma skin cancer in man is very, very common and is almost 100 percent curable with an operation usually simpler than a tooth filling,” Rees said in a statement. Conney said the mouse was a commonly used model in skin cancer but said he agreed that it does not perfectly replicate human skin and human behaviour. He said his team approached Johnson & Johnson to create a cream without the suspect products and they developed one using other readily available ingredients. “They are things that are commonly used in many moisturizing creams,” he said. This cream did not cause the tumours in the mice, they said. He said Rutgers and Johnson & Johnson had patented the new cream jointly but did not know whether it would be commercially developed. A spokesman at the company was not immediately available for comment.
