OBJECTIVES Surgical radiofrequency ablation is increasingly used during open heart surgery for the treatment of chronic atrial fibrillation. The purpose of this study was to determine the effects of application of radiofrequency on coronary endothelial function and structure and establish the relationship between coronary lesions and distance of radiofrequency application. METHODS Six Landrac...

AIM To compare 5-year survival of patients with a single hepatocellular carcinoma≤3 cm randomly assigned to receive percutaneous ethanol injection or radiofrequency ablation. PATIENTS AND METHODS A total of 285 patients (192 males, mean age 70 years), with a single hepatocellular carcinoma (mean diameter 2.2 cm) were randomly assigned to receive percutaneous ethanol injection (n=143) or radio...

background: the health effect of rapidly increasing everyday exposure of humans to radiofrequency radiation is a major global concern. mobile phone jammers prevent the mobile phones from receiving signals from base stations by interfering with authorized mobile carriers’ services. in spite of the fact that mobile jammer use is illegal, they are occasionally used in offices, shrines, conference ...

an air filter is a significant element of any mechanical ventilation system. however, the importance and performance evaluation of air filters have not been well publicized and related scientific reports are scarce. in this study, a transportable, off-line, air filter-testing unit (the unit) was designed and utilized to simulate the filter housing of a mechanical ventilation system. the unit wa...

conclusions both tens and prf lumbar sympathectomy are promising pain relief treatments for painful dnp. however, prf lumbar sympathectomy seems to have a superior efficacy. further studies with a larger sample size and a longer follow-up period are needed. background painful diabetic peripheral neuropathy (dpn) is a long-term complication of type 1 and type 2 diabetes that majorly impacts qual...

conclusions radiofrequency ablation may be used successfully in the treatment of parathyroid adenoma when a patient cannot tolerate surgery. case presentation a 47-year-old patient was referred to our hospital (namazi hospital, shiraz, iran) in april, 2015 with intracranial hemorrhage, as well as high serum calcium and pth (parathyroid hormone) levels (12.1 mg/dl and 1062 pg/ml, respectively), ...

physical agents such as ultraviolet or ionizing radiation and repetitive trauma have been related to the causation of cancer in humans. much less clear is the association between exposure to radiofrequency, such as radar and microwave radiation to the development of cancer. sporadic case reports and small series suggest that this type of radiation might lead to cancer or contribute to its evolu...

introduction: one of the minimally invasive methods of treatmenting liver malignancies is radiofrequency ablation (rfa) which can be applied to primary or secondary tumors. nevertheless, the disease recurrence is probable after rfa application partially due to the inadequate capability of temperature monitoring of the target tissue and visualizing the thermal damage. the goal of this work was t...

patients and methods this was a retrospective study including 207 consecutive patients who were enrolled using computerized hepatocellular carcinoma database consisting of 105 patients who underwent combined tace with rfa, and 102 patients who underwent tace alone with long-term follow-up. results the complete remission rate was meaningfully higher in the combination group (97.1%, 102/105) than...

AIMS Although arrhythmia surgery and radiofrequency catheter ablation to cure atrioventricular nodal reentrant tachycardia differ in technical concept, the late results of both methods, in terms of elimination of the arrhythmogenic substrate and procedure-related new and different arrhythmias, have never been compared. This constituted the purpose of this prospective follow-up study. METHODS ...
