Checks have revealed that the test sometimes gives a false negative result. Women who have been tested in the past three months have been advised to contact their GP or NHS Direct if they think they might be pregnant, despite the test saying they were not. The manufacturer of the kits is recalling them. Home-testing kits are not affected. The problem with the SAS 1 Step kit was first spotted during routine checks at the University Hospital of North Durham. This story is covered in all of today's papers. Pill that brings hope to millions of men Source: Daily Mail / Date: 18/02/2004 A new pill to help men cope with premature ejaculation could be on the market in the UK by 2007. It has been developed by Enhance Biotech and has been tested on 30 men already. As 29% of men suffer from the condition, compared with one in ten men suffering from impotence, it could outsell Viagra. GPs currently recommend psychotherapy or prescribe SSRIs to combat premature ejaculation. The new treatment, called LI301, combines the effects of an SSRI with an 'opiate-like' dulling of sensation around the sexual organs, reducing the intensity of feelings. It takes effect after two hours. A bellyful of bugs - do probiotics work? Source: Times 2 / Date: 18/02/2004 Some studies show that regular dosage with probiotic supplements can help to prevent colon cancer. A recent Japanese study compared the health benefits of wheat bran biscuits and a daily supplement of Lactobacillus casei, a probiotic, for the prevention of colon cancer. Fewer people taking the latter developed colorectal tumours. Probiotics found in breast milk are vital nutrients for babies and can help prevent allergies and boost immunity to infections. A further study on rats has shown that probiotics can raise levels of key immune cells, especially natural killer cells. Raised levels of NK cells lower the risk of tumours in the colon. Ultrasound could kill cancer cells Source: The Guardian / Date: 16/02/2004 Researchers have developed invisible scalpels of ultrasound that can roast a tumour a bit at a time in a series of two-second bursts. The ultrasound scalpels don't cut any other tissue, and they avoid the side-effects usually associated with cancer surgery. So far, 76 patients have been treated with the technique at the Royal Marsden Hospital, without any need for sedation. Twenty patients have been treated under anaesthetic in Oxford with an instrument imported from China. Around 3,000 patients have been treated at 20 centres in China. The British trials have been concerned with safety, and more systematic trials involving larger numbers of patients are planned. Warning on fish link to autism Source: Daily Mail / Date: 16/02/2004 Researchers in America have warned that pregnant women who eat tuna could be putting their unborn children at risk of autism. They believe that levels of mercury in oily fish such as tuna and swordfish could be behind the rise in autism in children. The Food Standards Agency in the UK advises pregnant and breastfeeding women to limit their consumption of tuna to two medium cans a week. However, Ray Rice of the Fish Foundation said: 'There is lots of evidence to show a very positive link between seafood and pregnancy.' Calcium link to fertility Source: The Guardian / Date: 16/02/2004 Gordon Woods of the University of Idaho has told the conference of the American Association for the Advancement of Science that calcium appears to play a role in fertility, according to his studies on cloned mules. He says the vital ingredient in the process of triggering growth in the embryos could have been extra calcium in the surrounding fluid. Woods believes that calcium also plays a role in cancer risk. Horse red blood cells contained 2.3 times less calcium than human red blood cells. Conversely, levels of calcium in the fluid around the horse blood cell were much higher. Equines in general were far more resistant to cancer than humans, Woods said. Cancer is linked to antibiotics Source: Daily Express / Date: 16/02/2004 A new study has claimed that women who frequently use antibiotics could increase their risk of getting breast cancer by as much as 50%. Health records of 10,000 women, some as young as 19, showed a clear link between the risk of cancer and the amount of antibiotics taken, according to researchers in Seattle. In Britain, one in 12 women is at risk from breast cancer, and this could increase to one in eight among high users of antibiotics such as penicillin. Antibiotics may raise the risk of getting cancer more than the contraceptive pill or HRT. Taking antibiotics for minor conditions such as acne also appeared to increase the risk. Opportunists microbes lurk in your shower Source: Financial Times / Date: 16/02/2004 Norman Pace, a microbiologist at the University of Colorado, has warned of the billions of germs that live in the folds of shower curtains. At the American Association for the Advancement of Science conference he described how 'soap scum is a lush bed of microbes generally embedded in a biofilm matrix'. He added, 'When you switch on the shower, you immediately generate a bio-aerosol.' His microbial analysis of five domestic shower curtains, including his own, showed high levels of bacteria that can cause respiratory and other diseases in those with weakened immune systems. Another study showed high levels of pathogenic bacteria in the air above an indoor heated swimming pool. Oil your stiff joints Source: Times 2 / Date: 16/02/2004 Dr Thomas Stuttaford looks at how fish oil can stave off osteoarthritis and can help people on nitrates. Rheumatologists at the University of California have shown that patients with angina, in particular women, whose condition is treated with nitrates are twice as likely to develop osteoarthritis of the hip as those who have used other drugs to keep their chest pain under control. The journal General Practitioner suggests that patients taking nitrates could attempt to curb any further breakdown of cartilage by taking more omega-3 in their diet. Fish oil is the easiest means of increasing omega-3 in the diet. Fish oil is also thought to have beneficial effects on intellectual ability during middle age and beyond. Cod liver oil - nature's super drug Source: Daily Mail / Date: 13/02/2004 Scientists say cod liver oil is so effective it should be hailed as a natural 'wonder drug'. In a study, scientists recruited 31 patients on a Health Service waiting list who were due to have surgery to replace knee joints. They found that cod liver oil is highly effective in slowing the destruction of joint cartilage in patients with arthritis. They believe that a daily dose of cod liver oil could help to delay the onset of arthritis, and have called upon people as young as 20 to start taking it to protect their joints. Fish oil also cuts the risk of heart attacks and strokes by helping to thin the blood, and contains essential fatty acids which are crucial for maintaining brain health. Scientists propose cure for dyslexia Source: The Times / Date: 13/02/2004 Scientists at the University of Washington in Seattle have developed a technique to teach dyslexic children to recognise the relationships between a word's letters, sounds and meaning. After three weeks of this training, the brains of dyslexic children start to work in a similar fashion to those of children without any reading disability, according to evidence from MRI brain scans. The method appears to work by teaching dyslexic children to use the most appropriate parts of the brain to process different aspects of what they read. The new technique was pioneered by Virginia Berninger and Elizabeth Aylward. Autistic brains read faces as objects Source: The Times / Date: 13/02/2004 Researchers working at the University of Washington in Seattle have found that the brains of people with autism respond abnormally when processing unfamiliar faces. When looking at such faces, the sufferer will employ a part of the brain normally used to process objects. Adults normally use a part of the brain called the fusiform gyrus to process faces. This ability emerges during childhood, and is normally well-developed by the age of 12. Another part of the brain, the temporal gyrus, is used to process visual information about objects, which do not convey the emotional signals often found in facial expressions. Autistic children use the inferior temporal gyrus to process information about faces. Smoking 'kills up to 5,000 foetuses a year' Source: Daily Telegraph Date: 12/02/2004 A study by the British Medical Association has found that smoking causes up to 5,000 miscarriages and 1,200 cervical cancer cases a year, as well as making 120,000 men impotent, reducing fertility and increasing the risks of childhood cancer. The study also found that second-hand smoke increases the risk of cot death, glue ear and asthma in babies. The BMA described the findings as 'frightening', and has called for tough anti-smoking measures, including help for pregnant women to avoid passive smoking at work. The study is the first attempt to bring together all the medical evidence about smoking, fertility, pregnancy and childhood health. Doctors demand action to defuse Britain's huge obesity time bomb Source: The Times / Date: 12/02/2004 Health experts from organisations including The Royal College of Physicians have called on the Government to implement sweeping changes in diet, behaviour and education to prevent one third of adults, a fifth of boys and a third of girls becoming clinically obese by 2020. Scientists from The Royal College of Physicians, the Faculty of Public Health, and the Royal College of Paediatrics and Child Health have warned of the 'terrifying' increase in type 2 diabetes in children as a result of the obesity epidemic. More than half of Britain is either overweight or obese, and Carol Black, president of the Royal College of Physicians, said: 'The size of the problem has been underestimated.' 'A hungry foetus makes a fat adult' Source: Financial Times / Date: 12/02/2004 The UN Food and Agriculture Organisation has warned that women who go hungry during pregnancy could be "programming" foetal tissue to get the most out of available food energy, leading to overnourishment in adulthood when coupled with more food and a more sedentary lifestyle. People in a third of the world's countries already consume more than the recommended cholesterol and fat levels. תוכן ההודעה: תגובות נוספות 19/2/2004  9:10 יהודית, תודה! ואוי ווי גדול לגבי הטונה והאוטיזם... טובה, היכנסי.
