How the heat from a laptop can 'toast' the skin on your thighs

Warning: A 12-year-old boy shows off the 'toasted skin' on his leg after using a laptop for several hours a day



  • 'Toasted' boy used laptop for a few hours a day




  • Damage can lead to skin cancers in some cases




  • Temperature underneath computer can hit 52C 



  •  In one recent case, a 12-year-old boy developed a sponge-patterned skin discolouration on his left thigh after playing computer games for a few hours every day for several months.
    'He recognised that the laptop got hot on the left side, however, regardless of that, he did not change its position,' Swiss researchers wrote in the medical-journal Pediatrics.

    Another case involved an American law student with a mottled discolouration on her leg.
    Her doctors were stumped until they learned she spent about six hours a day working with her computer propped on her lap.
    The temperature underneath the device reached 52c and, placed under the microscope, the affected skin resembled skin damaged by long-term sun exposure.
    The case, from 2007, is one of ten laptop-related incidents reported in medical journals in the past six years, but many more are likely to have gone unrecorded.
    Danger: Balancing a laptop on bare legs can can cause permanent skin darkening
    Although the condition is usually harmless, it can cause permanent skin darkening.
    In very rare cases, it can cause damage leading to skin cancers, said the Swiss researchers, Andreas Arnold and Peter Itin, of the University Hospital Basel.
    'Toasted skin syndrome' can also affect bakers, silversmiths and others whose jobs involve being exposed to heat.
    Major computer manufacturers including Apple, Hewlett Packard and Dell warn in user manuals against placing laptops on laps or exposed skin for extended periods because of the risk of burns.
    The researchers warned that children's skin is particularly susceptible to heat.
    But Dr Bav Shergill, a consultant dermatologist and spokesman for the British Association of Dermatologists, urged people not to worry.
    He said: 'It usually resolves itself without any permanent skin discolouration.'

    Genes discovered that decide whether we will be tall or short




    Lofty ambitions: Scientists hope to track down all the genetic mutations that determine if we will be tall like John Cleese or short like Ronnie Corbett
    Scientists have pinpointed why some people shoot up to become superstar basketball players while others struggle to reach 5ft.
    The genetic finding is a giant stride towards explaining why comedian John Cleese towers over his friend Ronnie Corbett.
    While obesity is caused by a mix of genetic and environmental factors, about 80 per cent of variation in human height is determined by our genes.

    Now researchers have identified hundreds of mutations that account for about 10 per cent of the inherited difference in height among people.
    Study leader Professor Joel Hirschhorn of Harvard Medical School, said: 'Height clearly has a lot to do with genetics - shorter parents tend to have shorter children, and taller parents tend to have taller children.
    'This paper is the biggest step forward to date in understanding which of the genetic variants that differ between people account for our differences in height.'
    The GIANT (Genetic Investigation of ANthropometric Traits) Consortium pooled millions of pieces of genetic data from more than 180,000 individuals in the US, Canada, Europe and Australia.

    Teenage girl is star musician who plays five instruments... despite being completely DEAF

    Doctors are mystified as to why Aimee-Louise Paddock went deaf this May. Despite her condition she continues to excel playing five different musical instruments

    A talented teenage girl who plays five instruments has won top marks in her latest music exam - despite being unable to hear a single note.
    Aimee-Louise Paddock, who is totally deaf, was inspired to take up the saxophone after watching the cartoon character Lisa Simpson play it on TV's 'The Simpsons.'
    The 18-year-old from King's Lynn in Norfolk also plays the flute, keyboard, piano and the guitar to a high standard. She has applied to study a four-year music degree course at the Royal Welsh College of Music in Cardiff.

    Aimee-Louise lost her hearing in the left ear aged just 16 and became fully deaf in May. Doctors are mystified as to what has caused the sudden hearing loss after an MRI scan showed no sign of tumours or blockages.
    The A-level student can only understand speech by lip reading but despite this she is a member of several orchestras including the West Norfolk Junior Youth Orchestra.

    School for stammers: How specialist lessons helped this young boy beat his stutter - and the classroom bullies

    Confident: Ann Basic and her son Steven after the therapy. The 12-year-old youngster suffers from a severe stammer

    Autumn term is always a mix of trepidation and excitement as children head back to school after the long summer holidays, but Steven Babic used to dread that first day more than most.
    The 12-year-old youngster suffers from a severe stammer that became worse as each new academic year approached - and Steven knew he would be the butt of endless jokes in the playground and the classroom.
    'They'd treat me as if I was contagious or as if I was thick, and it used to make me so angry and upset,' he admits.
    His parents, Ann and Milan, felt useless, having no idea how to help their son other than offer soothing words of comfort as he broke down in tears.
    But this month, Steven, who lives in Wapping, East London, walked through the gates of the London Nautical School, Waterloo, with his head held high.
    For the first time since he was ten, he sounded confident and fluent with no hint of the speech problem that has dogged his life.
    'I've wanted to be a pilot for Virgin for as long as I can remember but thought I'd have no chance  -  who wants a stammering pilot? But now I actually believe I can achieve my dream,' he says.
    Steven and his parents are among 200 people referred annually to the Michael Palin Centre for Stammering Children in Finsbury, North London, which provides specialist therapy to deal with both the speech difficulties and the confidence issues facing youngsters who stammer.

    DR ELLIE CANNON: Viagra fails to work for half of all men...here's why

    Viagra will work only if testosterone levels have been normalised

    Doctors say Viagra helps only half of the men who are prescribed it. DR ELLIE CANNON explains why.
    Q. Why does Viagra sometimes not work?
    A. Low testosterone levels are a common cause of erectile dysfunction (ED). Testosterone is the male sex hormone and levels decline with age. Viagra will work only if testosterone levels have been normalised first. Low testosterone levels can be improved with pills, patches and gels.
    Q. If I tell my doctor I have ED, what tests should they do?
    A. Blood tests need to be done to rule out a testosterone problem, as well as diabetes and thyroid disease. Other blood tests for hormone, liver and kidney problems should be carried out and your BMI will be measured, as obesity is a cause of ED. Your relationship can also be a factor, as well as your mood. Depression is a significant cause of erectile problems.
    Q. The problem began when I started my blood-pressure medication. Is that possible?
    A. Yes  -  ED can be a side effect of many drugs including anti-depressants, diuretics and beta-blockers as well as those prescribed for high blood pressure.
    Q. What are the alternatives?
    A. Drugs called Levitra and Cialis act in a similar way. Injections and urethral creams can also be effective.

    Some OCD sufferers keep washing their hands...I feared I’d murder my daughters


    Diana was convinced her thoughts would see her locked up in a mental institution should she ever reveal them to anyone
    Diana Wilson was convinced her thoughts would see her locked up in a mental institution should she ever reveal them to anyone

    In this shocking account, one mother describes how she overcame an obsessive fear of harming those she loved most
    She bears all the hallmarks of a yummy mummy – a slight frame, carefree blonde hair, a country manor home, a wealthy lawyer husband and four gorgeous daughters.
    Yet Diana Wilson has a very dark secret. Her story is so disturbing that many will find it hard to comprehend.
    She suffered for nearly 30 years from violent, murderous fears of harming others – some so graphic that they cannot be printed.She was convinced that these thoughts would see her locked up in a mental institution should she ever reveal them to anyone. What Diana did not realise was she was suffering from a rarely discussed form of Obsessive Compulsive Disorder (OCD) where symptoms include an obsessive fear of harming others.
    Thanks to insightful doctors, Diana was to discover that OCD can be cured with Cognitive Behavioural Therapy (CBT) and she has now tackled her inner demons to the extent that she lectures on mental-health issues.
    Diana is holding a silver-framed photo of her four beautiful daughters today aged ten to 16. ‘Ten years ago I was preparing to hand over these little girls I loved to strangers for their own safety, then be driven off to Broadmoor in a Black Maria,’ she says.
    She reveals how she simultaneously imagined strangling, drowning, slashing with a razor blade or pushing off an escalator her own family.

    How a walnut 'could stop you cracking under the strain'


    Walnuts
    Cracking: Walnuts may help alleviate stressful situations
     They have already been credited with helping reduce cholesterol.
    But it appears walnuts may help the body deal with stress and reduce blood pressure too.
    According to research, those with high levels of bad cholesterol had lower blood pressure in stressful situations when they had been on a diet rich in walnuts for three weeks.
    For the study, participants were asked to give a three-minute speech or immerse one foot in cold water – both of which are triggers for stress.
    Those with walnut in their diets had lower blood pressure, said Professor Sheila West, from Penn State university.
    ‘This is the first study to show that walnuts reduce blood pressure during stress.
    People who show an exaggerated biological response to stress are at higher risk of heart disease.’

    Gym-goers 'are wasting money on sports drinks'


    A person in a gym

    Fitness enthusiasts who buy energy sports drinks are probably wasting their money, according to an expert.
    While the drinks may be suitable for people training for events such as marathons, many exercisers just end up consuming lots of extra calories.
    Nick Hudson, national fitness manager for Virgin Active, said those doing workouts of less than two hours do not really benefit from the drinks.

    Thousands of gym-goers who buy energy sports drinks are wasting their money an expert has said
    ‘Many people drink energy drinks in the belief they will give them more energy to exercise harder,’ he said.
    ‘But many are simply “calorie drinks” and drinking them means you’ll have to train longer or harder to shift the calories that you take in from the drink itself.
    ‘They’re useful for people who compete in events where they’ll be exercising in excess of two hours. But those doing shorter, more intense workouts don’t really benefit physiologically.’

    Personality disorders raise risk of ulcers

                                               Red alert: Helicobacter pylori
    Personality may be a key to who develops stomach ulcers, writes Roger Dobson.
    According to research, those with a personality disorder are up to five times more likely to develop a peptic ulcer.
    ‘Manifestations of peptic ulcer disease are influenced by mind-body interactions,’ says Dr Jean-Pierre Schuster, who led the study at Descartes University, Paris, and the Centre for Addiction and Mental Health, Toronto.
    Although stress has long been associated with the risk of ulcers, the discovery of links with Helicobacter pylori infection led to less attention being paid to psychological factors.
    The bacterium causes peptic ulcers by damaging the mucous coating protecting the stomach and duodenum.
    Just how personality factors could have such an effect is far from clear but there are a number of theories.
    One idea is that certain personality types, such as dependant personality, may be more likely to be involved in health-risk behaviour, such as smoking, sleeplessness and irregular meals.
    Another theory is that some personality factors trigger a stress response from hormones that have a detrimental effect on the immune system.

    I kept my leukaemia a secret. I am Big Ed and I didn't want to be seen as sick or vulnerable

    Literary agent Ed Victor was diagnosed with a cancer of the blood called CLL - chronic lymphocytic leukaemia (above with client Nigella Lawson)
    Literary agent Ed Victor went for a routine medical on September 9, 1999, which, he says wryly, was 'to celebrate my 60th birthday'.
    The burly American was told that his white blood cell count was elevated, indicating either a healthy response to a mild infection or white blood cells being overwhelmed by millions of inactive ones  -  a sign of leukaemia.
    It turned out to be the latter. However, Ed  -  arguably the world's leading literary agent with a client list that includes Nigella Lawson, Frederick Forsyth, Sophie Dahl and the rock band U2  -  says that he had no idea what a raised blood count might mean and was not alarmed.

    Why are women being used as guinea pigs for facial fillers?

    More than 1.25 million people in the UK will have a non-surgical procedure this year in a market worth £1.7billion
    Anna Macintyre used to be a confident woman. These days the 43-year-old marketing manager from Essex holds her hand over her mouth when she talks. Two years ago she decided to plump up her lips with a dermal filler.
    Her lips were overfilled, which stretched the skin and led to red veins above her top lip.
    'I can't believe that I destroyed my looks trying to look better,' she says. Unfortunately, she has no idea what she was injected with.
    This is no isolated case  -  for although there are 147 injectable fillers available in the UK, only seven of these have the approval of the Food and Drug Administration (FDA). According to the latest figures from Mintel, more than 1.25 million people in the UK will have a non-surgical procedure this year in a market worth £1.7billion.

    Can pomegranate juice put a halt to middle-aged spread?

    It can help prevent cancer, is good for your heart and can even boost your sex life.
    If that wasn’t enough to tempt you to drink some, it is now claimed that pomegranate juice can also help shift middle-age spread.
    Scientists believe that the superfood has the power to reduce the fat stored round the stomach – the ‘spare tyre’ in men, or ‘muffin top’ in women.
    After just one month, volunteers who consumed a bottle of pomegranate
    juice every day were found to be less likely to develop fatty cells around their abdomen.
    They also had much lower blood pressure, therefore reducing their risk of heart attacks, strokes and kidney disease.
    The researchers from the University of Edinburgh believe pomegrate juice may lower the amount of fatty acid in the blood, known as nonesterified fatty acid or NEFA.
    Previous studies in humans and animals have shown that high NEFA levels are linked to a greater storage of fat around the abdomen, as well as an increased risk of heart disease and type II diabetes.
    In the experiment, 24 men and women were given a 500ml bottle of pomegranate juice to drink every day for four weeks.
    The researchers found that nearly half of all volunteers had much lower NEFA levels by the end of the trial. They believe that this will make them less likely to store fat around their stomach.
    In addition, more than 90 per cent of the men and women had lower blood pressure by the end of the month.

    Poor sleep for mothers-to-be raises risk of birth problems


    Woman sleeping in bed

    Newly pregnant women who get less than five hours sleep a night are more likely to suffer from problems in birth, research shows.
    They are ten times more at risk from pre-eclampsia, a condition which causes high blood pressure, leading to organ damage and even the death of the unborn baby.
    It can also be fatal for the mother who, once diagnosed, is given a Caesarian or drugs to induce the birth prematurely.
    Having a lie in: Pregnant women are advised to sleep for longer than eight hours
    Mothers-to-be who get five hours sleep or less a night within the first 14 weeks are ten times more at risk, the American researchers found.

    During sleep, a person's average blood pressure falls by between 10 and 20 per cent.

    This means that those who sleep for fewer hours a night will have a higher-than-average blood pressure over a 24-hour period.

    Flu vaccination may lower heart attack risk: study

    British researchers have found in their new study that preventing the flu can lower the chances of heart attacks in some people, suggesting there may be a link between respiratory infections and heart attacks.

    According to Monday's online issue of the Canadian Medical Association Journal, the researchers, led by Dr. Niroshan Siriwardena of the University of Lincoln, with co-authors Stella Gwini and Carol Coupland, looked at 78,706 patients aged 40 years or older from 379 family practices in England and Wales.

    Of the total, 16,012 had had a heart attack and 8,472 of the patients had been vaccinated.

    The researchers found that early vaccination for flu - between September and mid-November - was associated with a 21 percent reduction in the rate of heart attacks compared with late vaccination after mid-November, which was associated with a 12 percent reduction.

    "Our findings reinforce current recommendations for annual influenza vaccination of target groups, with a potential added benefit for prevention of acute myocardial infarction in those without established cardiovascular disease," the study said.

    However, pneumococcal vaccination was not linked to a reduction in the rate of heart attacks, the researchers found.

    If the findings are borne out by future studies, then it could lead to changes in the recommended timing and indications for flu shots, the researchers concluded.

    The findings are not proof of a link, but they offer another piece of evidence on the benefits of flu shots for people with chronic illness and others who may not be aware of their heart health.

    Other ways of avoiding flu, such as hand washing or staying away from crowds, could also play a role in preventing heart attacks.

    The study was funded by the U.K.'s National Institute for Health Research.
