PURPOSE We report initial ex vivo and in vivo studies using bipolar radiofrequency (RF) ablation of porcine kidneys. An internal ground electrode is positioned in the kidney opposite the RF electrode, resulting in ablation of all the intervening renal tissue. MATERIALS AND METHODS Ex vivo preparations of 10 porcine kidneys were perfused continuously with Ringer's solution and treated with eit...

Introduction T1 hyperintense renal lesions may represent hemorrhagic/proteinaceous cysts or neoplasms. The visual assessment of enhancement of these lesions can be difficult, and signal intensity measurements before/after contrast injection and qualitative analysis of enhancement with image subtraction can be used in that purpose. We wanted to determine the accuracy of apparent diffusion coeffi...

UNLABELLED Cowpox viruses (CPXV) cause hemorrhagic lesions ("red pocks") on infected chorioallantoic membranes (CAM) of embryonated chicken eggs, while most other members of the genus Orthopoxvirus produce nonhemorrhagic lesions ("white pocks"). Cytokine response modifier A (CrmA) of CPXV strain Brighton Red (BR) is necessary but not sufficient for the induction of red pocks. To identify additi...

Enoxaparin is a low-molecular-weight heparin used in the prevention and treatment of pulmonary thromboembolism and other thrombotic disorders. The most common adverse reactions to enoxaparin are ecchymosis, skin necrosis, urticaria, angioedema, and eczema. The first 2 cases of bullous hemorrhagic dermatosis in areas distant from heparin injection sites were described in 2006. We present the cas...

Thirteen turkeys naturally affected with hemorrhagic enteritis were studied pathologically. The main gross lesions were splenomegaly and hemorrhagic contents in the gut. The main histological lesions were intranuclear inclusion bodies in largemononuclear cells in many visceral organs and in reticular cells around the sheathed arteries of the spleens and varying degrees of lymphocytic hyperplasi...

Six adult dairy cows clinically diagnosed as hemorrhagic bowel syndrome (HBS) were the subjects of this study. The involved intestinal lesions were fixed in formalin and examined macroscopically and histopathologically. Pathological examinations revealed large intramural hematomas with necrotic foci, resulting in luminal obstruction. The mucosal layer in the lesions was detached from the intest...

southeast of iran is an endemic area for malaria and crimean-congo hemorrhagic fever ( cchf). in 1999, we faced with an outbreak of cchf in sistan and baluchistan province, in the border of paki­stan and afghanistan. the most cases of malaria in iran are also reported from this area. this arti­cle presents a 17-year- old woman who admitted to our hospital because of acute fever, head­ache, epis...

PURPOSE To report a case of peripheral exudative hemorrhagic chorioretinopathy (PEHCR) in an elderly patient. CASE REPORT A 74-year-old Caucasian woman, with a 20-year history of a stable choroidal nevus in her right eye, was referred for evaluation of two small hemorrhagic pigment epithelial detachments (PEDs) affecting the temporal peripheral fundus of the same eye. Nine months later, the l...
