3−week history of fatigue and headaches was admitted with suspected myocardi− tis. Echocardiography showed a dilated left ventricle with a shortening fraction of 12%. Electrocardiography revealed ec− topic atrial tachycardia, with a heart rate of 200 beats per minute. Cardioversion was performed to terminate the tachycar− dia, but this was unsuccessful. Intrave− nous amiodarone was started, but...

We examined 170 formalin-fixed paraffin-embedded samples from esophageal squamous cell carcinoma patients. All subjects live in Mazandaran province, a region with high incidence rate of esophageal cancer and have become known as the “Asian Esophageal Cancer Belt”. Samples were tested for HPV-DNA by MY09/11 and Gp5+/6+ general primers using nested PCR. Of the 170 ESCC samples, 86 (50.6%) were ma...

The influence of circularly polarized electric fields (CPEFs) on the stability of multiarmed spiral waves is investigated. It is shown that CPEFs can change the period of the multiarmed spirals. The average period is an important quantity of multiarmed spiral and it must be larger than a threshold for stable multiarmed spiral. After a counter-rotating CPEF with suitable amplitude and period is ...

The pattern of injury seen in pediatric hand burns differs from adults because scald burns are most common. Many of these are difficult to assess at initial presentation. In addition, children develop less stiffness in response to immobilization. For these reasons, we have developed a conservative, expectant approach for treating most pediatric hand burns. Meticulous wound care, positioning, sp...

ingested corrosive substances produce different injuries, ranging from minor gastro esophageal burns to death, depending on the agent type, amount, concentration, and duration of substance exposure. the purpose of this study was to investigate the outcomes and different causes of mortality in patients ingesting caustic substances. in a prospective study, between april 1999 and january 2006, a t...
