SYDNEY, Aug. 2 (Xinhua) -- Australia's general practitioners ( GPs) will not back the idea of routine prostate cancer tests for men as young as 40 despite growing calls for regular screening, the nation's largest professional general practice organization said on Tuesday.Spokesman for the Royal Australian College of General Practitioners (RACGP), Professor Chris Del Mar said there was not enough solid evidence to suggest major benefits from routine screening and that current tests were unable to detect "nasty" and potentially deadly forms of prostate cancer from ones that will not cause any harm."The problem is you end up treating lots of people who don't need to be treated," Del Mar said, adding that treatment could leave men impotent and with incontinence problems."You will treat 20 times as many people than would have ever been bothered by it. We don't yet know that treating prostate cancer is better than not treating it. We are not sure it does any good and could be doing more harm," he said.On the other hand, Australia's urologists and pathologists both want men aged 40 and over who are worried about developing the disease to be offered tests.The Royal College of Pathologists (RCPA) on Tuesday released an official recommendation on routine screening for men aged 40 and over if they were concerned about prostate cancer.The pathologists argue that blood tests for prostate cancer in men under 50 can predict their future risk of developing the disease by measuring their prostate specific antigen levels (PSA).They say that men with high PSA levels for their age should be tested annually, while those PSA levels are below the average could be tested less frequently.Their call for more routine testing contrasts with recommendations for GPs, whose `Red Book' medical guide does not support regular screening.Instead, it suggests GPs should inform men aged 50-70 of the risks and benefits of screening and only test if the patient requests one.RACGP spokesman Del Mar, who co-wrote the RACGP's recommendations, said while the Red Book was being revised "we are not going to liberalize it".Prostate cancer is one of the most common forms of cancer in Australia.About 20,000 cases of prostate cancer are diagnosed each year, with 3,300 men dying.Given the debate around prostate cancer tests, the Royal College of Pathologists wants to work with GPs, urologists and other medical organizations to develop a consensus on how and when to test for the disease, in a similar way to how experts approach breast cancer."It would be a good outcome for prostate cancer if we worked towards developing more of an umbrella document which reflected consensus among different stakeholder organizations. ," RCPA President Paul McKenzie said.

PARIS, June 14 (Xinhua) -- Solar Impulse, a Swiss solar-powered aircraft, finally arrived in Paris on Tuesday after three days' delay, ready for a debut at the biennial International Paris Air Show.The 1.6-ton solar-powered plane was expected to land in Paris on Saturday but technical problems and bad weather forced it to turn back to Brussels.The plane took its first international flight from Switzerland to Brussels on May 13 and then marked its second international flight to Paris. It has 12,000 solar cells mounted on the wings, which provide momentum for its four electric motors.Solar Impulse is the first aeroplane designed to fly day and night without requiring fuel and without producing carbon emission. The 64-meter-wingspan (as wide as an Airbus A340) can fly at extremely slow speed and has a weight equivalent to that of an average family car.Regarded as a "special guest" in the show, Solar Impulse made a historic 26-hour day and night flight without fuel in July 2010.During the Paris air show from 20 to 26 June, visitors can enjoy a close look at the innovative plane on ground every day and if weather condition permits, flying displays will take place.According to Paris Air Show organizers, 59 of the top 100 companies in the air industry worldwide will be present. More than 1,800 small and medium-sized companies will be exhibiting their products during the one-week show. Enditem

GENEVA, Aug. 12 (Xinhua) -- 18 people seeking treatment at hospitals in Somalia had been confirmed cholera positive through laboratory tests, the Geneva based World Health Organization (WHO) said on Friday.The 18 positive cases were detected out of 30 stool samples collected from patients seeking treatment at hospitals for acute watery diarrhea, a symptom that could result from cholera, WHO spokesperson Tarek Jasarevic told reporters.All confirmed cases, including residents of Mogadishu district and those among internally displaced persons (IDPs), were said to be tested positive for the Vibrio cholera serotype "inaba", which had been the predominant serotype in Somalia for the past three years."These results are an alarming reminder of the critical situation in Mogadishu and other parts of Southern, Central Somalia, (which are) still experiencing drought, population displacement and conflict," Jasarevic said.WHO has reported a dramatic increase of acute watery diarrhea cases in Somalia.In June and July alone, 1,633 acute watery diarrhea cases had been registered in Banadir Hospital, Mogadishu, representing 38 percent of all reported cases in 2011, and a sharp rise comparing with the same period last year.The United Nations public health arm said the situation was related to poor sanitation and limited access to safe water in numerous informal IDP settlements and a limited capacity of existing health partners to access those settlements and provide essential health services.In addition, the high number of malnourished children due to the ongoing famine increased the susceptibility to waterborne diseases.
