Kawasaki disease is a rare but serious condition in children that involves inflammation of the blood vessels, specifically the heart vessels that supply the heart tissue or coronary arteries. It is the most common cause of pediatric acquired heart disease in the developed world.
Children with Kawasaki disease or illness caused by adenoviruses often first present with a high and persistent fever. Early diagnosis for Kawasaki disease before the tenth day of fever is essential to prevent sequelae in the heart.
“Kawasaki disease and acute adenoviral infection can present with many of the same clinical characteristics,” says Preeti Jaggi, MD, member of the Section of Infectious Diseases at Nationwide Children’s and lead study author.
“Given the similarities, human adenovirus infection is one of the most frequent conditions included on the differential diagnosis when considering Kawasaki disease.” However, few data are available regarding the differences in frequency, viral load and types of detectable human adenovirus in Kawasaki disease patients and in children who have adenovirus disease that mimicks Kawasaki disease.
The study aimed to determine whether there are differences in the amount of human adenovirus in the upper airway in children with human adenovirus infection versus those diagnosed with Kawasaki disease. Dr. Jaggi and her team compared Kawasaki disease patients who were positive for human adenovirus infection with other patients diagnosed with human adenovirus infection during a two year period at Nationwide Children’s. Among 77 Kawasaki disease patients, nearly 13 percent had human adenovirus detected.
“Evidence suggests that human adenovirus strains can persist in pediatric adenoids and tonsils and are capable of low level shedding. PCR analysis can detect non-replicating virus,” says Dr. Jaggi, also assistant professor of Clinical Pediatrics at The Ohio State University College of Medicine. “This may explain why PCR, but not viral culture, could detect human adenovirus in these Kawasaki disease patients.”
The findings indicate that detection of human adenovirus in a patient with suspected Kawasaki disease should be interpreted with caution. “Detection of human adenovirus in these patients is fairly common and does not exclude the diagnosis of Kawasaki disease,” says Dr. Jaggi.
According to Dr. Jaggi, quantitative PCR, culture and human adenovirus typing methods may help distinguish human adenovirus disease mimicking Kawasaki disease from Kawasaki disease with accompanying human adenovirus detection.

University of Würzburg physicists have succeeded in creating a new type of laser.
Its operation principle is completely different from conventional devices, which opens up the possibility of a significantly reduced energy input requirement. The researchers report their work in the current issue of Nature.

Researchers have shown that, by using global positioning systems (GPS) to measure ground deformation caused by a large underwater earthquake, they can provide accurate warning of the resulting tsunami in just a few minutes after the earthquake onset.
For the devastating Japan 2011 event, the team reveals that the analysis of the GPS data and issue of a detailed tsunami alert would have taken no more than three minutes. The results are published on 17 May in Natural Hazards and Earth System Sciences, an open access journal of ...
A new study of glaciers worldwide using observations from two NASA satellites has helped resolve differences in estimates of how fast glaciers are disappearing and contributing to sea level rise.
The new research found glaciers outside of the Greenland and Antarctic ice sheets, repositories of 1 percent of all land ice, lost an average of 571 trillion pounds (259 trillion kilograms) of mass every year during the six-year study period, making the oceans rise 0.03 inches (0.7 mm) per year. ...
About 99% of the world’s land ice is stored in the huge ice sheets of Antarctica and Greenland, while only 1% is contained in glaciers.
However, the meltwater of glaciers contributed almost as much to the rise in sea level in the period 2003 to 2009 as the two ice sheets: about one third. This is one of the results of an international study with the involvement of geographers from the University of Zurich.
