Israeli Researcher: Chewing Gum Cause of Migraines in Teens

Thursday, December 19th, 2013

Teenagers who love chewing, smacking and bubble-popping gum may be giving themselves a headache, according to research by Dr. Nathan Watemberg of Tel Aviv University-affiliated Meir Medical Center. His findings, published in Pediatric Neurology, could help treat countless cases of migraine and tension headaches in adolescents without the need for additional testing or medication.

Dr. Watemberg noticed at Meir’s Child Neurology Unit and clinics that many patients who reported headaches were daily gum chewers. Teenage girl patients were particularly avid chewers — a finding supported by previous dental studies.

He asked 30 patients between six and 19 years old who had chronic migraine or tension headaches and chewed gum daily to quit chewing gum for one month. After a month without gum, 19 of the 30 patients reported that their headaches went away entirely and seven reported a decrease in the frequency and intensity of headaches. To test the results, 26 of them agreed to resume gum chewing for two weeks. All of them reported a return of their symptoms within days.

“Out of our 30 patients, 26 reported significant improvement, and 19 had complete headache resolution,” said Dr. Watemberg. “Twenty of the improved patients later agreed to go back to chewing gum, and all of them reported an immediate relapse of symptoms.”

Aspartame, a common ingredient found in sugarless gum, has long been suspected of causing neurological damage. Prior to the European Food Safety Authority recently declaring the artificial sweetener as safe, studies have suggested it may provoke headaches in susceptible individuals. However, the Israeli researchers believe that the amount of aspartame released in gum is likely to be low because the flavor of gum is typically lost after the first few minutes of chewing. Rather, they believe the likely reason for the link between gum-chewing and headaches is the stress on the TMJ.

“Every doctor knows that overuse of the TMJ will cause headaches,” Dr. Watemberg said in a statement. “I believe this is what’s happening when children and teenagers chew gum excessively.”

A possible explanation for the association that exists between chewing gum and headaches is the stress placed on the temporomandibular joint (TMJ), where the skull and jaw meet. Chewing gum causes unnecessary wear and tear of the cartilage that acts as a shock absorbent in the jaw joints, which can lead to pain and discomfort, Dr. Ben Kim, who is not not involved in the study. told the website Medical Daily.

Gum chewers use eight different facial expression when they chew. If used excessively, this can create chronic tightness in two of these muscles that are located near an individual’s temples. Therefore, the nerves that are on this area of the head feel extreme pressure, which can lead to chronic, reoccurring headaches.

Israeli Developer of Swallowable Camera Bought for $860 Million

Monday, December 9th, 2013

An Irish company will purchase Given Imaging Ltd., an Israeli firm that developed a swallowable camera to diagnose problems in the digestive tract.

Covidien Plc agreed to acquire Given Imaging from shareholders of IDB Holding Corp. Ltd. for about $860 million, it was reported Sunday. Given Imaging is the inventor of the PillCam, a swallowed optical endoscopy technology.

Covidien acquired three other Israeli medical device companies, all in 2012.

IDB subsidiaries Discount Investment Corp., Elron Electronic Industries and Rafael Development Corp. hold stakes in Given Imaging. The three companies were set to approve the deal on Sunday, which also must be approved by shareholders of Given Imaging.

Israeli Invents New Super Glue for Internal Surgery Incisions

Wednesday, December 4th, 2013

Israeli Prof. Havazelet Bianco-Peled of Haifa’s Technion University has invented a new super glue that mechanically seals areas of potential leakage after surgery, without the need for sutures.

Bianco-Peled set up the Sealantis start-up at Technion in 2007, and the company now is expecting FDA approval for the “Seal-V” glue, developed from the cell walls of brown algae.

Seal-V retains its sealant capacity even on wet surfaces,” said Bianco-Peled. The glue also is biorestorbable, meaning that the body automatically absorbs it after the wound heals.

Israeli Doctor Can Help Make You into a Real Man

Monday, October 14th, 2013

Tel Aviv University researchers didn’t have an immediate diagnosis for the under-masculinized young man, a former soldier, who walked into their clinic one day.

But they and the soldier didn’t know that they were beginning a years-long medical journey that would lead the researchers to discover a new genetic mutation, bolster the case for a counterintuitive medical treatment, and push the limits of male fertility.

Dr. Karen Tordjman, a senior lecturer at Tel Aviv University’s Sackler Faculty of Medicine didn’t have an immediate diagnosis for the under-masculinized young man who walked into her office.

A 25-year-old university student who had served in an elite commando unit in the Israeli navy, he was handsome in a fashion-model kind of way – rail thin, with a smooth face and delicate, feminine features. Closer inspection revealed no body hair other than sparse patches in his armpits and groin. His genitals were small and heavily scarred.

The young man had reluctantly agreed to visit the medical clinic at the insistence of his girlfriend, who wanted an explanation for his condition. He couldn’t have known he was initiating a years-long medical journey that would lead Dr. Tordjman and a team of physicians to discover a new genetic mutation, bolster the case for a counterintuitive medical treatment, and push the limits of male fertility.

“We offered treatment not for his future reproductive capabilities but for his appearance,” says Dr. Tordjman. “We didn’t guarantee him anything, but we said we’d try.”

Her research, published in the journal Andrologia, will allow future genetic screening for the mutation.

Dr. Tordjman and her colleague Dr. Amnon Botchan, also a Sackler lecturer, began by obtaining the patient’s medical records. The records showed that two of his uncles had been diagnosed with androgen receptor insensitivity — a rare condition that results in the body under-responding to the androgen hormones that drive male sexual development. Usually caused by a mutation in the androgen receptor gene, the condition impairs the development of male genitalia in the womb and of secondary male sexual characteristics during puberty.

In cases of complete androgen insensitivity, no male sexual development takes place. The result is men who look like women on the outside but have testes rather than female genitalia inside their bodies. Such cases are often diagnosed only during puberty, when the individuals develop breasts and other female sexual characteristics but do not start menstruating.

Dr. Tordjman’s patient, who reported a consistent heterosexual orientation, had not had sex reassignment surgery or been given androgen treatments to try to enhance his sexual development at birth. But he had been diagnosed with the same condition as his uncles and undergone operations to correct genital malformations at age three and to remove breast tissue during puberty. Genetic testing, performed with the help of French researchers Dr. Serge Lumbroso and Prof. Charles Sultan, confirmed that he had a mutation of his androgen receptor gene — one that had not previously been reported.

Hoping to masculinize the patient per his wishes, Dr. Tordjman started him on high-dose testosterone therapy. Theoretically, this type of therapy makes little sense for patients with androgen receptor insensitivity, because their bodies create plenty of testosterone — it’s just that they are unable to put it to use. But Tordjman had read about a case in which the therapy had worked and decided to give it a try.

After several months of weekly injections, the patient appeared dramatically more masculine. He gained 18 pounds — mostly of muscle — and grew hair on his face and body, leading him to shave for the first time in his life. His voice, which had always been high-pitched, did not change. The voice, says Tordjman, is stubbornly resistant to hormone therapy.

The treatments continued for four years, during which the patient and his girlfriend got married and eventually began talking about having a baby.

Infertility in men with androgen receptor insensitivity is nearly universal, even in mild cases; and no one with a case as severe as the patient’s was known to have successfully fathered a child. But having seen a significant improvement in his sperm count, Tordjman took another long shot and referred the couple for fertility treatment. When Tordjman next saw the patient several years later, he was pushing a baby girl into her office in a stroller.

Israelis Star in Nobel Prizes, so Why Doesn’t BDS Boycott Them?

Wednesday, October 9th, 2013

Three more Jews, two of them with Israeli citizenship, won the Nobel Prize in chemistry Wednesday, bringing to two the number of professors associated with Israeli universities who have been awarded Nobel prizes so far this year. Most of the winners have been Jews.

The-three man all Jewish team of Professors Aryeh Warshel, Michael Levitt and Martin Karplus, won the prize in chemistry for the development of multi-scale models for complex chemical systems.

Warshel is an Israel who was born in Kibbutz Sde Nachum, studied at Haifa’s Technion Institute and earned his doctorate at the Weizmann Institute of Science in Rehovot, south of Tel Aviv. Levitt, who also holds Israeli citizenship, was born in South Africa and is a professor at Stanford University. Karplus was born in Austria in 1930 and in 1938 escaped to the United States, where he earned his doctorate at the California Institute of Technology

Intentionally or not, TIME magazine’s report did not note that two of the winners were Israeli citizens.

It is doubtful that TIME was suddenly being so pro-Israel that it wanted to bury the facts from the Boycott Israel movement, which includes academics in Britain and other countries in Europe as well some in Australia who want to punish for the supposed “occupation” Israel by breaking off ties with its universities.

That would mean the Israelis would not be able share research with them, but in this childish game, it is the anti-Zionists who would lose out. Perhaps they deserve their own punishment. If the BDS folks were intellectually honest, they would protest against the Nobel Prize judges for awarding professors from Israleli universities.

There also is plenty of leeway for the anti-Semitic crowd to claim that Jews, including a Holocaust survivor, are running the world since they have won no less than six of the Nobel prizes awarded this week. A couple of non-Jews also have been recognized, and their numbers will likely rise as prizes are announced in the fields of literature and peace.

Francois Englert, a Belgian Jewish professor at Tel Aviv University and a Holocaust survivor, shared the Nobel Prize in physics Tuesday for their discovery of the Higgs particle, known as the “God particle,” which is said to have caused the Big Bang.

On Monday,  Jewish Americans James Rothman of Yale University and Randy Schekman of the University of California, Berkeley, joined German-born researcher Thomas Suedhof, a non-Jew from Stanford University, in winning  the Nobel Prize in medicine.

Israeli leaders were as excited as the Nobel Prize winners in chemistry, if not more so.

President Shimon Peres called and congratulated Prof. Warshel and joked, “How does it feel for a man from the kibbutz to win a Nobel Prize?”

President Peres continued and said, “I want to congratulate you on behalf of the State of Israel and the Jewish people and every person who hopes to overcome sickness and suffering because of your work. I am sure that your breakthrough will lead to advances in medicine and further scientific breakthroughs.”

He asked Prof. Warshel to convey his congratulations to the other prize winners, professors Levitt Karplus.

Israelis have won no less than six Nobel prizes in the past 11 years.

The BDS movement has not commented.

Two Jews Win Nobel Prize in Medicine

Monday, October 7th, 2013

Two more Jews, both from the United States, and a German non-Jew won the Nobel Prize in medicine in Monday, while two Israel contenders lost out.

The newest Jewish Nobel Prize winners are James Rothman of Yale University and Randy Schekman of the University of California. The Israeli hopefuls  were Hebrew University professors Howard Cedar and Aharon Razin.

More than 20 percent of the 800 Nobel Prize winners so far have been Jewish although Jews represent only 0.2 of the world’s population.

The third winner Monday was Dr. Thomas Sudhof of Stanford University. All three scientists shared the $1.2 million for their research on how tiny bubbles are carriers inside cells, making sure that the right elements arrive at the right place and at the right time.

This year’s Nobel Prizes in other fields are to be announced  within the next two weeks.

UPDATE: And yet another Jew has won a Nobel Prize in Physics.

Israel Raises Funds to Treat Ethiopian Boy Mauled by Hyena

Wednesday, July 3rd, 2013

Israeli officials have joined international efforts to save an 8-year-old boy who was mauled by a wild hyena in Ethiopia.

Bedouin-Israeli diplomat Ismail Khaldi and Israel’s ambassador to Ethiopia, Belaynesh Zevadia, are spearheading a campaign for contributions for bringing Abdul Razek to the Western Galilee Hospital in Nahariya.

Five months ago, the hyena attacked Abdul’s village, killing five and injuring 15. Abdul suffered severe head, scalp and eye injuries, and lost one of his ears. The estimated cost of the operation is $40,000.

With most of the money raised, it is expected the boy could come to Israel by the end of the week.

Dr. Rick Hodes of the American Jewish Joint Distribution Committee is on a mission in Ethiopia and interceded with the hospital on behalf of the child.
