CT scans show patients with severe cases of H1N1 are at risk for developing acute pulmonary emboliOctober 14, 2009Researchers utilizing computed tomography (CT) scans have found that patients with severe cases of the H1N1 virus are at risk for developing severe complications, including pulmonary emboli (PE), according to a study to be published online Oct. 14, 2009, in the American Journal of Roentgenology. The study will be published in the December issue of the AJR. A pulmonary embolism occurs when one or more arteries in the lungs become blocked. The condition can be life-threatening. However, if treated aggressively, anti-coagulants (blood thinners) can reduce the risk of death. The study, performed at the University of Michigan Health Service, included 66 patients diagnosed with the H1N1 flu. Two study groups were formed. Group one consisted of 14 patients who were severely ill and required Intensive Care Unit (ICU) admission. Group two consisted of 52 patients who were not severely ill and did not require ICU admission. All 66 patients underwent chest X-rays for the detection of H1N1 abnormalities. Ten patients from the ICU group and five patients from the largely outpatient group, underwent CT scans. "Pulmonary Emboli were seen on CT in five of 14 ICU patients," said Prachi P. Agarwal, M.D., lead author of the study. "Our study suggests that patients who are severely ill with H1N1 are also at risk for developing PE, which should be carefully sought for on contrast-enhanced CT scans," she said. "With the upcoming annual influenza season in the United States, knowledge of the radiologic features of H1N1 is important, as well as the virus's potential complications. The majority of patients undergoing chest X-rays with H1N1 have normal radiographs. CT scans proved valuable in identifying those patients at risk of developing more serious complications as a possible result of the H1N1 virus, and for identifying a greater extent of disease than is appreciated on chest radiographs," said Dr. Agarwal.

Image-guided treatment for deep venous thrombosis could improve patients' long-term outcomes Deep Venous Thrombosis (DVT) is a serious condition that involves the formation of a blood clot inside of a deep vein usually in the legs. A patient with DVT is typically treated with anticoagulants (blood thinners) however researchers have found that image-guided interventional radiology procedures may play a more central role in the long-term treatment of DVT. Researchers Find a Way to Reduce Patient Radiation Dose During Pulmonary CT Angiography While screening for possible pulmonary emboli using pulmonary CT angiography, a new study shows that radiologists can effectively lower the patient radiation dose by approximately 44% and improve vascular enhancement without deterioration of image quality. Emergency Physicians Don't Follow Established Clinical Guidelines for Diagnosing Patients with Possible Pulmonary Emboli The number of MDCT examinations for suspected pulmonary emboli (PE) is rapidly increasing amongst ER patients, with a decrease in the number of positive studies. Educating Physicians About Ventilation-Perfusion Scanning Leads to Reduced Patient Radiation Exposure Educating physicians about ventilation-perfusion scanning (VQ) as an alternative to CT for the diagnosis of pulmonary embolisms led to a 23% decrease in patient exposure. Radiation Dose Can Be Reduced For "Triple Rule-Out" Coronary CT Angiography Physicians can dramatically reduce the radiation dose delivered to patients undergoing coronary CT angiography in a "triple rule-out" protocol by simply using tube current modulation, according to a study performed at Thomas Jefferson University Hospital in Philadelphia, PA. Radiologists encouraged to look beyond cancer for clinically unseen diseases Radiologists can diagnose venous thromboembolic disease (VTED) in cancer patients earlier by looking more carefully at CT scans of the thorax, abdomen, and pelvis which are regularly done to determine the extent or stage of the cancer. Study Compares Clinical Diagnoses and Autopsy Diagnoses in ICU Deaths Comparing clinical diagnoses with autopsy findings for patients who died in intensive care units (ICUs) provides information about underlying missed diagnoses, according to an article in the February 23 issue of The Archives of Internal Medicine, one of the JAMA/Archives journals. According to the article, autopsy rates have decreased worldwide. The reasons for the decline in autopsy rates are attributed to fear of potential legal repercussions should misdiagnoses be discovered, reluctance of families to give permission for the procedure, and doubt regarding the usefulness of autopsies given today's modern diagnostic techniques. Recent studies suggest that major discrepancies between clinica A new pathway for halting neuronal death in Huntington's disease The body is an extremely complex puzzle in which every piece plays a critical role. Should pieces disappear harmony is compromised. Such is the case with certain neurodegenerative diseases; when neurons suddenly die, the body's ability to function properly is jeopardized. CNRS (1) and INSERM biologists from the Curie Institute are working to understand how neurons die in one specific neurodegenerative disease: Huntington's disease. They have just announced the discovery of two new factors capable of blocking cell death induced in Huntington's disease. They may eventually provide targets for the therapeutic treatment of this type of disease.
