There is no scientific evidence that complementary therapies or kits sold through websites can identify allergies, the UK NHS watchdog NICE says. It says sites for services such as hair analysis use plausible stories but are not backed up by scientific evidence. It is publishing new guidance to help doctors in England and Wales identify when a child may have allergy problems. NICE says some parents end up turning to alternative therapies after a perceived lack of help from their GPs.
It is estimated that one in 20 young children has a food allergy. Dr Adam Fox, an allergy specialist based at the Evelina Children's Hospital in London, says not all children suffer immediate and obvious symptoms. “Food allergies can actually be extremely subtle. Lots of children have eczema, colic or spit up more food than usual. For some of those children the underlying problem is an allergy to something within their diet.”
The guidelines include detailed advice about how to recognise symptoms and when to refer to specialists. Dr Fox, who helped write the guidelines for National Institute for Health and Clinical Excellence (NICE), says he often sees parents in his specialist clinic who have wasted money on complementary or alternative tests.
The review by NICE looked for any scientific research of the usefulness of approaches including hair analysis and Vega testing, which uses mild electric currents, or kinesiology, in diagnosing allergies in children. “The websites are very well put together, the stories behind them are plausible, but we were unable to find any evidence to support them,” says Dr Fox. He says there are two types of testing used in NHS clinics – skin prick and blood sample – which are backed by scientific research. NICE is warning that parents sometimes turn to alternative tests when they have failed to convince their family doctor to listen to their concerns.
It took Alison Berthelson more than two years to get an allergy diagnosis for her first son Harris. She had been to the local surgery several times when he suffered rashes and stomach upsets without any particular cause being identified. After Harris ate a small piece of chocolate containing nuts he suffered a more extreme reaction, becoming agitated, with an extreme rash covering his entire body. The out-of-hours GP gave her son a medicine to reduce swelling, but did not send him on to hospital as an emergency. “It was really very terrifying, terrifying at the time because we didn't know what was happening, and terrifying later when we did know what had happened and how lucky we were.” A new GP correctly diagnosed possible food allergies, and sent Harris for testing at a specialist NHS clinic. He now has to avoid nuts, sesame and some other ingredients used in prepared foods.
Allergies on rise The number of children suffering from food allergies appears to be increasing, although experts are at a loss to understand exactly why. Family doctors are now more likely to see very young children suffering allergic reactions. Dr Joanne Walsh, a GP involved in drafting the advice, says she now sees several children a week with suspected allergic reactions. Some are babies just a couple of weeks old. By gradually eliminating, and reintroducing different foods, she can help parents manage the allergy without the need for hospital visits. “There's nothing more rewarding than a parent coming back and saying it's like having a different child.”
About one in seven Britons feels under extreme stress, a survey suggests.We can reasonably conclude that these numbers will be similar right here in Australia. Experts say stress raises blood pressure, putting people at greater risk of stroke. A poor diet and lack of exercise also contribute to the chances of suffering a stroke. Stroke is the third leading cause of death in the United States. Over 143,579 people die each year from stroke in the United States. Stroke is the leading cause of serious, long-term disability in the United States. Each year, about 795,000 people suffer a stroke. About 600,000 of these are first attacks, and 185,000 are recurrent attacks. Almost one in five women and one in 10 men feel their stress levels are out of control, according to the poll of 2,000 people in Britain.
The survey, by the Stroke Association and the engineering company Siemens, found almost a fifth of people said they took no exercise. A similar number said they exercised for 30 minutes once a week. More than a quarter of people aged 45 to 54 said they never exercised, despite suffering the highest stress levels. Almost half said they were under more than “moderate stress”. Overall, 40 per cent of those surveyed said they were unaware of the link between exercise and lowering the risk of stroke.
James Beeby, of the Stroke Association, said: “The research is incredibly worrying and emphasises the need for people to be aware of the dangers of stroke. “It’s imperative that people take regular exercise and modify their diet to reduce the risk of suffering a stroke.” Siemens sponsors the British rowing team and provides some funding for the Stroke Association’s Stroke for Stroke campaign. Andreas Goss, the chief executive of Siemens in the UK, said: “Contrary to popular belief, stroke can affect people of any age.”

To this end, the following emotional variables have been specified: those relative to emotional experience —the frequency of positive and negative emotions, anxiety, low self-esteem and the influence of diet, weight and the body shape on the emotional state—; negative perception of emotions, negative attitude to emotional expression, alexithymia —the inability to identify own emotions and to express them verbally— and the manner of controlling negative emotions.
Moreover, another variable has also been taken into account: the need for control. This variable is not strictly emotional, but has a clear emotional component, given that people with a high need for control, experience anxiety and unwellness when perceiving lack of control.
Study of women
In order to undertake the study, 433 women took part; 143 of these suffered from some kind of eating disorder and 145 in risk of contracting one. The results of the study show that, in general, the majority of the variables put forward can be used as predictive of suffering an eating disorder. The variables which, above all, alert to greater risk of developing an eating disorder are when the emotional state of the person is excessively influenced by diet, weight and body shape, when self-esteem is low, and when, in anxiety situations, emotions are not expressed and the person tends to act in an impulsive manner.
These results have important implications, above all when drawing up prevention programmes for eating disorders. With the data obtained, it can be said that many of the emotional variables dealt with in Ms Pascual's work should be taken into account when drawing up these prevention programmes.
Eating disorders are very serious illnesses that have dire consequences for the sufferer, both physically as well as psychologically and socially, and there are disorders that are evermore widespread. Much research has been undertaken in order to find out the factors involved in their development, but the role played by the various emotional variables at the onset of these disorders has hardly been investigated. This thesis presented at the UPV/EHU focused on this matter more deeply.
