Researchers from the United Kingdom analyzed adverse incidents encountered in pediatric  CEUS , and sought to determine if there were financial benefits to reducing the number of CT and MRI examinations among children. The researchers analyzed all CEUS examinations performed on children aged 18 and younger between January 2008 and December 2015. The children received a median dose of 2.4 mL of a  sulfur hexafluoride microbubble  contrast agent, with ranges from 0.1 mL to 4.8 mL. All immediate reactions deemed due to contrast examinations were documented in radiology reports. Electronic patient records were examined for adverse reactions within 24 hours not due to an underlying pathologic condition. Costs were also compared: CEUS utilization cost at $94, CT at $168, and MRI at $274. The results showed that of 187 boys and 118 girls (305 children total), 147 studies (48.2%) were ordered to characterize liver lesions and 113 studies (37.1%) for trauma. The remaining 45...

Arteriosclerosis, Thrombosis, and Vascular Biology  conclude that the chemicals used to create these flavors could be damaging blood vessels and the cells that line the inside of the heart. Electronic cigarettes  (e-cigarettes) were first introduced to the United States in 2006 and were marketed as a safer alternative to cigarettes. These battery-powered devices heat a liquid solution that is then inhaled by the user. However, e-cigarettes can still contain nicotine and some of the chemicals used in regular cigarettes. Since their introduction, they have gained popularity and are widely used as an alternative to smoking traditional tobacco products. They are often used to help people quit smoking with the belief being that they offer fewer health risks. They have also gained popularity among young people. According to the Centers for Disease Control and Prevention ( CDC ), there was an increase in middle and high school students using e-cigarettes...

Adults with varicose veins - gnarled, enlarged veins, most commonly appearing in the legs and feet - may be at increased risk of suffering from blood clot that could lead to vascular diseases, a study has found. The study found people with varicose veins were at a five times increased risk of developing a deep venous thrombosis (DVT) -- a clot in the legs which can lead to amputation or even death, the Daily Mail reported. They were twice as likely to develop a pulmonary embolism -- a clot which travels into the lungs and can be deadly.They also had double the risk of peripheral arterial disease, which reduces blood flow to the arms and legs. The study led by researchers including Pei-Chun Chen, adoctoral student from China Medical University in Taiwan, examined 212,984 patients aged 20 years and older with varicose veins, and a control group of equal patients without varicose veins. The results, published in the journal JAMA, showed that among adults diagnosed with varicose ...
