H1N1 NEWS SCAN: Radiographic, autopsy findings

H1N1 2009 Pandemic Influenza

Jun 17, 2010

Chest x-ray may underestimate infections
To gauge the relationship between symptoms and signs of disease on radiographic tests, researchers reviewed records of 157 hospitalized patients who had confirmed pandemic H1N1 infections. Researchers report in the British Journal of Radiology that chest x-ray abnormalities were found in only 33% of cases and were linked to breathing difficulties. The test was less sensitive than computed tomography among immunocompromised patients.

Autopsy study finds unique traits of H1N1 flu
An autopsy study of H1N1 patients found peripheral pulmonary vascular thrombosis occurred in 5 of the 8 fatal cases, compared with 3 of 8 controls, according to an American Journal of Clinical Pathology report. Researchers also found cytophagocytosis in all of the flu-related cases. They found that the two features distinguished H1N1 cases from other flu types and that hemophagocytic syndrome should be suspected in severe H1N1 patients.
