BACKGROUND Radiofrequency (RF) treatment is a minimally invasive procedure that has been used for more than 3 decades in treating various chronic pain syndromes. Conventional (continuous) RF treatment occasionally results in worsening or even initiating a new type of pain. The use of pulsed radiofrequency (PRF), which has a non- or minimally neurodestructive neuromodulatory effect, serves as an...

Background: Malignant biliary and/or pancreatic obstruction has often encountered in the advanced stages of periampullary and cholangicarcinomas. HabibTM Radiofrequency (RF) ablation has been successfully used in the management of various cancers of liver and pancreas. Percutaneous HPB probe (EMcision Ltd, London, UK) is a new addition to this class of tools. It is an endoluminal Radiofrequency...

We present the case of a 52 year-old male with a history of C-hepatitis and two liver neoplastic lesions treated by radiofrequency (RF) ablation. The patient wears an abdominally-implanted unipolar VVI pacemaker that did not show any signs of interference during RF pulses. We describe the procedure performed and discuss the present knowledge regarding the possibilities of RF interference with t...

avnrt, (atrioventricular nodal reentry tachycardia), atrial tachycardia and atrial flutter are 3 kinds of supraventricular tachycardia, which their mechanism are explained based on reentry. a 60-years-old man is presented with all of the above-mentioned arrhythmias, responsive to intravenous injection of adenosine. radiofrequency ablation of the slow pathway territories cured all of them. there...

Objective: The purpose of this study was to determine the incidence of new-onset pelvic pain within 2 years after either radiofrequency (RF) or thermal balloon (TB) endometrial ablation for menorrhagia. Study design: This study was a retrospective cohort study of consecutive patients treated by radiofrequency or thermal balloon global endometrial ablation (GEA) between 2003 and 2008. Setting: T...

[Purpose] This study aimed to compare the efficacy of radiofrequency diathermy with that of microwave diathermy in combination with intra-articular injection of hyaluronic acid into the knee of patients with osteoarthritis (OA). [Subjects] A total of 17 patients with knee OA were enrolled. The participants were randomly divided into two groups: a radiofrequency diathermy group (RF group, 9 subj...

We describe measurements of plasma properties of pulsed, low pressure, capacitively coupled discharges operated in argon. The research aims to determine the effect of modulating the radiofrequency power during the discharge part of the pulse cycle. Measurements of local electron density and optical emission were made in capacitively-coupled rf discharges generated in a Gaseous Electronics Confe...

The rapid development of and the increase in the number and variety of devices that emit microwave/radiofrequency (MW/RF) energies has resulted in a growing interest regarding the potential effects on health of these energies. The frequency ranges considered in this review are: 300 kHz to 300 MHz (radiofrequency) and 300 MHz to 300 GHz (microwaves). Investigations have shown that exposure to ce...

In this study, the mutagenic effects of low power radiofrequency radiation on Zea mays root tip were studied. Cells in different division phases and chromosomal aberration assay were used to determine the mitotic index and chromosomal aberration frequency of Zea mays root tip cells induced by 900MHz radiofrequency radiation. Zea mays seeds, having a uniform genophond, have been exposed to RF fi...

INTRODUCTION Cryoablation is used increasingly for the treatment of atrioventricular nodal reentrant tachycardia (AVNRT). We sought to compare the long-term outcomes of cryoablation (Cryo) vs. radiofrequency (RF) ablation for the treatment of AVNRT in children. METHODS Two groups of consecutive patients were analyzed retrospectively: the RF group, 20 patients (60% males, mean age 13.25 +/- 2....
