Intravenous mercury administration is a rare occurrence that is typically associated with accidental injections or suicide attempts. We report the case of a 42-year-old man who attempted suicide by injecting mercury into the left cubital vein. Upon arrival at the emergency department, he was in a state of alcohol intoxication and there were signs of vein puncture and cellulitis in his left arm....

Case Presentation: A 71-year-old man with coronary artery disease, left ventricular (LV) systolic dysfunction (ejection fraction, 30%), and recent admission for heart failure presented with acute dyspnea and hypoxemia. A pro-brain–type natriuretic peptide level was elevated at 2450 pg/mL (normal 350 pg/mL). Chest x-ray demonstrated cardiomegaly and small bilateral pleural effusions. After an ho...

Background: Man-made  radionuclides, which are present in environment, have been created by human activities and added to the inventory of natural radionuclides for example 3H, 131I, 129I, 137Cs, 90Sr and 239Pu, in spite of the amount added is little compared to natural quantities. The aim of this study is to estimate the levels of radiological doses in the soil samples collected from different...

osteoblastoma is a rare benign, but locally aggressive bone tumor with rare malignant transformation. it mostly affects the vertebral column and long bones. radiographically, it is seen as an expansile, oval, sclerotic or lytic mass-like lesion with well-defined borders, although sometimes it may mimic a malignant tumor such as osteogenic sarcoma by its irregular borders. herein, we report a ca...

a 19-year-old man presented with a 5-year history of back pain radiating to the lower extremities and paresthesis of the toes during the last year. plain x-ray revealed a large cauliflower shaped exophytic mass at the level of t8, t9 and t10 vertebrae. computed tomography (ct) and magnetic resonance imaging (mri) showed an abnormal bony mass arising from the posterior arch of t9 with protrusion...

A 67-year-old Japanese man underwent enterotomy because of enterolith ileus. Component analysis by infrared spectroscopy revealed that the enterolith was composed of a high concentration of deoxycholic acid. We further analyzed and compared the ultrastructure of the enterolith and a commercially available powdered form of deoxycholic acid by means of scanning electron microscopy and energy disp...

Chronic eosinophilic pneumonia. The chronic eosinophilic pneumonia is part of Pulmonary Eosinophilic Syndroms. It is presented a 33-years old man, Asmathic, with dry cough, fever, night sweats and fatigue of several weeks. The chest X-ray showed opacity in the right hemithorax. He was treated with antibiotics without response. A chest TC showed multifocal involvement. The patient refused bronch...

In 1906, Werner and Lichtenberg reported that choline injections in rabbits produce sterility or lessened fertility, analogous to the effects of x-ray or thorium X, which was followed by Werner and Asher, reporting blood and skin changes similar to that produced by x-ray (1-4). The above was countered by Seckfort and Weise recently, who reported that choline injections do not produce a falling ...

While the expenses for computational power decrease, iterative reconstruction methods for x-ray computed tomography (CT) that allow the use of improved model assumptions, become more attractive. In applications for non-destructive testing one of the most common degradations of image quality with standard x-ray CT reconstruction methods is beam hardening. Techniques for beam hardening correction...
