Soldiers serving in the Middle East who develop breathing difficulties — but whose chest x-rays show nothing ordinary — have zaciskajacego acute bronchiolitis, a type of lung is practically unknown in the young adult survey.
Reporting on July 21, the New England Journal of medicine, physician Robert Miller, Vanderbilt University in Nashville and his colleagues documented condition in 38 49 soldiers studied, served in Iraq and Afghanistan and offered up with lung problems. Zaciskajacego acute bronchiolitis in which narrowed airways become narrow, carried soldiers unfit for active duty.
"Most of them say they did not seem to be catching their breath when exerting themselves," says study coauthor Matthew King, pulmonologist at Meharry Medical College, also in Nashville. And although anti-inflammatory medicine and steroids inhalation can help symptoms, says soldiers with acute bronchiolitis does not improve. "We have seen no reversibility."
Researchers discovered the condition, removing and analyzing small bits of lung tissue from soldiers who turned up badly from 2004 to 2009. All 49 of these biopsies showed abnormal tissue despite normal x-rays and inflammation in 38 soldiers indicated zaciskajacego acute bronchiolitis. Scarring and thickening of the tissues was common in this group, and all but one soldier harbored grayish black deposits of the lungs.
The origin and composition of deposits pneumonia remains unclear, King says. But the blackened nature of deposits of coal, suggesting fires signals.
Accumulating evidence of bad air in Iraq and Afghanistan. 2009 Survey of medical records to find more respiratory problems, personnel deployed there than in those stationed in other places. In March, scientists reported high levels of aluminum and lead in dust storms in Iraq (SN: 4/23/09, p. 15).
Anthony Shema, a doctor and an engineer at the University of Stony Brook, New York, has examined a soldier and that the small complexes of titanium and iron lung man, where the metals can cause scarring, inflammation and damage. Mined separately, two metals could become total only by means of the production process, presented at the meeting of the Shema, the American Thoracic Society in Denver, where he presented case study. While the metals of origin is not clear, he suspects that exploding devices or incineration pits sent them atmospheric.
In the new study, researchers "took a very aggressive in learn why" the lungs of these soldiers, "says Andrew Shorr, pulmonologist at Georgetown University in Washington," Miller's diligence in pushing this as a problem, is a very legitimate concerns, "says Shorr, formerly in the Walter Reed Army Medical Center.
While the cases represent only a few dozen test hundreds of thousands of persons serving in the Middle East, there is additional to the overlooked how many may be acute bronchiolitis.
Shorr recommends that men care in the area until more is known. "If you're burning rubbish," says, "you wear a mask."
