Measles surges in UK years after vaccine scare
LONDON (AP) ? More than a decade ago, British parents refused to give measles shots to at least a million children because of a vaccine scare that raised the specter of autism. Now, health officials are scrambling to catch up and stop a growing epidemic of the contagious disease.
This year, the U.K. has had more than 1,200 cases of measles, after a record number of nearly 2,000 cases last year. The country once recorded only several dozen cases every year. It now ranks second in Europe, behind only Romania.
Last month, emergency vaccination clinics were held every weekend in Wales, the epicenter of the outbreak. Immunization drives have also started elsewhere in the country, with officials aiming to reach 1 million children aged 10 to 16.
"This is the legacy of the Wakefield scare," said Dr. David Elliman, spokesman for the Royal College of Paediatrics and Child Health, referring to a paper published in 1998 by Andrew Wakefield and colleagues.
That work suggested a link between autism and the combined childhood vaccine for measles, mumps and rubella, called the MMR. Several large scientific studies failed to find any connection, the theory was rejected by at least a dozen major U.K. medical groups and the paper was eventually retracted by the journal that published it. Britain's top medical board stripped Wakefield of the right to practise medicine in the U.K., ruling that he and two of his colleagues showed a "callous disregard" for the children in the study. Wakefield took blood samples from children at his son's birthday party, paying them about 5 pounds each ($7.60) and later joked about the incident.
Still, MMR immunization rates plummeted across the U.K. as fearful parents abandoned the vaccine ? from rates over 90 percent to 54 percent. Wakefield has won support from parents suspicious of vaccines, including Hollywood celebrities like Jenny McCarthy, who has an autistic son.
Nearly 15 years later, the rumors about MMR are still having an impact. Now there's "this group of older children who have never been immunized who are a large pool of infections," Elliman said.
The majority of those getting sick in the U.K. ? including a significant number of older children and teens ? had never been vaccinated. Almost 20 of the more than 100 seriously ill children have been hospitalized and 15 have suffered complications including pneumonia and meningitis. One adult with measles has died, though it's unclear if it was the disease that killed him.
The first measles vaccines were introduced in the 1960s, which dramatically cut cases of the rash-causing illness. Since 2001, measles deaths have dropped by about 70 percent worldwide; Cambodia recently marked more than a year without a single case.
Globally, though, measles is still one of the leading causes of death in children under 5 and kills more than 150,000 people every year, mostly in developing countries. Measles is highly contagious and is spread by coughing, sneezing and close personal contact with infected people; symptoms include a fever, cough, and a rash on the face.
Across the U.K., about 90 percent of children under 5 are vaccinated against measles and have received the necessary two doses of the vaccine. But among children now aged 10 to 16, the vaccination rate is slightly below 50 percent in some regions.
To stop measles outbreaks, more than 95 percent of children need to be fully immunized. In some parts of the U.K., the rate is still below 80 percent.
Unlike in the United States, where most states require children to be vaccinated against measles before starting school, no such regulations exist in Britain. Parents are advised to have their children immunized, but Britain's Department of Health said it had no plans to consider introducing mandatory vaccination.
Last year, there were 55 reported cases of measles in the United States, where the measles vaccination rate is above 90 percent. So far this year, there have been 22 cases, including three that were traced to Britain. In previous years, the U.K. has sometimes exported more cases of measles to the U.S. than some countries in Africa.
Portia Ncube, a health worker at an East London clinic, said the struggle to convince parents to get the MMR shot is being helped by the measles epidemic in Wales.
"They see what's happening in Wales, so some of them are now sensible enough to come in and get their children vaccinated," she said.
Clinic patient Ellen Christensen, mother of an infant son, acknowledged she had previously had some "irrational qualms" about the MMR vaccine.
"But after reading more about it, I know now that immunization is not only good for your own child, it's good for everyone," she said.

Electric and magnetic characteristics of a material which could be used in spintronics: Promising doped zirconia
May 17, 2013 ? Materials belonging to the family of dilute magnetic oxides (DMOs) -- an oxide-based variant of the dilute magnetic semiconductors -- are good candidates for spintronics applications. This is the object of study for Davide Sangalli of the Microelectronics and Microsystems Institute (IMM) at the National Research Council (CNR), in Agrate Brianza, Italy, and colleagues.
They recently explored the effect of iron (Fe) doping on thin films of a material called zirconia (ZrO2 oxide). For the first time, the authors bridged the gap between the theoretical predictions and the experimental measurements of this material, in a paper about to be published in The European Physical Journal B.
Spintronics exploit an intrinsic property of the electrons found in semi-conductors called spin, akin to the electrons' degree of freedom. This determines the magnetic characteristics, known as magnetic moment, of the material under study. The challenge is to create such material with the highest possible temperature, as this will ensure that its magnetic properties can be used in room-temperature applications.
To study iron-doped zirconia, they examined its magnetic properties and its electronic structure from both a theoretical and experimental perspective. They then compared theory and experiments to find the most stable configuration of the material. Theoretical work included first-principles simulations. In parallel, their experimental work relied on many different well-established analytical techniques, including X-ray diffraction, X-ray photoelectron spectroscopy, transmission electron microscopy, and alternating gradient force magnetometer measurements.
Sangalli and colleagues therefore gained a better understanding of doped zirconia, which features oxygen vacancies, playing a crucial role in providing its unique electronic and magnetic characteristics. They have also predicted theoretically how the deviation from the standard structure influences this material's properties. They are currently investigating, experimentally, how the magnetism evolves with changing concentrations of iron and oxygen vacancies to confirm theoretical predictions.

Movie review: Games with words get tense 'In the House' | The Salt ...
"In the House" ? Fabrice Lucchini plays a writing teacher who's impressed by the work of a student, in Francois Ozon's sexually charged drama.Cohen Media Group
Review ? Thriller plays on tension between fact, fiction.
French director Fran?ois Ozon?s latest, the insidiously creepy domestic thriller "In the House," ties knots in your stomach as it walks its characters through a moral swamp of truth and fantasy.
Mr. Germain (Fabrice Luchini) teaches writing and French literature in a Paris high school, where years of lackluster students and esteem-boosting educational theories have left him jaded. He shares his frustration with his wife, Jeanne (Kristen Scott Thomas), an art gallery manager worried that her gallery?s new twin-sister owners (both played by Yolande Moreau) are too provincial to approve of her sexually frank artists. Ozon?s inclusion of a sexual blow-up doll with Hitler?s face is, presumably, a commentary on artistic overreach, or something.

?In the House?
A writing teacher takes a student under his wing, but the story that emerges spells trouble for them both, in this sharp French thriller.
Where ? Broadway Centre Cinemas.
When ? Opens Friday, May 17.
Rating ? R for sexual content and language.
Running time ? 105 minutes; in French with subtitles.
Emerging from this sea of mediocrity is Claude Garcia (Ernst Umhauer), a student who not only does his assignments but seems to show a creative spark. In his writing, Claude details how he has befriended a classmate, Rapha (Bastien Ughetto), and insinuated himself in Rapha?s home ? where Rapha?s dad (Denis M?nochet) talks about his ego-deflating sales job, and where Rapha?s still-hot mom (Emmanuelle Seigner) pores over decorating magazines and dreams of a home makeover.
Germain warns Claude about writing mockingly about his classmates, but still finds Claude?s story compelling enough to tutor him through more chapters. But the lines ? between student and teacher, between writer and subject, and between documentation and fabrication ? all become blurry.
Ozon, adapting a Juan Mayorga play, generates maximum tension by burrowing into the deepening t?te-?-t?te between Germain and Claude, in which manipulation and rule-breaking threaten to undo them both. Claude?s depiction of the middle-class paradise of Rapha?s house, and the student?s growing attraction to Rapha?s mom, is intercut with wicked asides from Germain, who enters the scene like a ghostly critic.
The only fault of "In the House" is the ending. Germain tells Claude that a good ending is one that the reader (or viewer) doesn?t see coming, but then can?t see how it could have gone any other way. Alas, Ozon fails to achieve that, with a finale that?s muddled and a bit out of left field.
