In fatal cases of 2009 H1N1 influenza, the virus can damage cells throughout the respiratory airway, much like the viruses that caused the 1918 and 1957 influenza pandemics, report researchers from the National Institutes of Health (NIH) and the New York City Office of Chief Medical Examiner. The scientists reviewed autopsy reports, hospital records and other clinical data from 34 people who died of 2009 H1N1 influenza infection between May 15 and July 9, 2009. All but two of the deaths occurred in New York City. A microscopic examination of tissues throughout the airways revealed that the virus caused damage primarily to the upper airway -the trachea and bronchial tubes -but tissue damage in the lower airway, including deep in the lungs, was present as well. Evidence of secondary bacterial infection was seen in more than half of the victims. http://www.physorg.com/news179426586.html Medicine & Health Mon, 07 Dec 2009 16:43:54 EST news179426586 Eighteen single-point genetic variations indicate risk of recurrence for early-stage head and neck cancer patients and their likelihood of developing a second type of cancer, researchers at The University of Texas M.

Doctors - and patients who get shingles late in life - have also known for many years that some viruses, particularly the herpes virus, can lie dormant in a person's cells for long periods of time and then reactivate, causing disease. These viruses also cause significant disease in immunosuppressed people and those living with HIV/AIDS. http://www.physorg.com/news165515047.html Medicine & Health Mon, 29 Jun 2009 18:10:02 EST news165515047 Greater influence over everyday life, emotional support, and cultural and recreational activities help to enable teenage girls to withstand stress.
