SARS Found in Tears

22.06.2004


SARS, the highly infectious respiratory virus, has been found in tears, reveals a small study in the British Journal of Ophthalmology.

The finding suggests that tear analysis could not only be an effective means of diagnosing the infection, but also an unrecognised source of its spread, if appropriate preventive measures are not taken, say the authors.

Tear samples were swabbed from the tear ducts of 36 patients in Singapore with suspected SARS over 12 days in April 2003. Most of those thought to have the infection were healthcare workers, including nurses.



Eight of these patients subsequently turned out to have probable SARS.

Chemical analysis confirmed the presence of the infection in three of these patients; in one, the virus was found only in the tears. These patients had only recently become infected - they were tested within 9 days of the start of symptoms.

The other five patients had no discernible evidence of the virus in their tear samples. But their symptoms had started over 11 days earlier, suggesting that the tear duct sampling may be a sensitive test for early stage infection, say the authors.

If the infection is caught early, this could make treatment (and isolation) more effective, they say. But the presence of the virus in tears poses a hazard for healthcare professionals caring for these patients.

It is not unusual for viral particles to be present in the eye, say the researchers. Herpes viruses, chicken pox, Epstein Barr virus, hepatitis C and B, and measles have all been detected in tears. But these are the first reported cases of SARS in tear duct fluid, they say.

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Im Focus: Three Magnetic States for Each Hole

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
