Monopolar radiofrequency (RF) devices are well established treatment modalities for tightening facial skin. A 60-year-old woman presented with a desire to tighten the lax skin and improve the appearance of both upper arms. A combination unipolar and bipolar RF device may provide volume reduction as well as skin tightening in the upper arm.

Twenty-two patients undergoing CT-guided stereotaxic biopsies had intraoperative monopolar and bipolar impedance monitoring along the trajectory of the biopsy. Patterns of tissue impedance were retrospectively correlated with CT scans demonstrating decreased impedance generally corresponding to low density regions and increased impedance to the enhancing lesions.

Background Use of irrigation catheters increases the power supply energy to create transmural injury [Jais P., Shah D.C., Haissaguerre M. et al., 2000]. However, these data are based on the catheter procedures and concomitant monopolar endocardial ablation [Deneke T., Khargi K. et al., 2007]. The benefits of using irrigation during bipolar concomitant ablation has no reflection in the literature.

It has been recurrently observed that, for compound muscle action potentials (M wave) recorded over the innervation zone of the vastus lateralis, the descending portion of the first phase generally shows an "inflection" or "shoulder." We sought to clarify the electrical origin of this shoulder-like feature and examine its implications. M waves evoked by maximal single shocks to the femoral nerv...

Introduction: Tonsillectomy is the most commonly performed surgeries in otolaryngology. Despite evolution surgical and anaesthetic techniques, pain bleeding are still important complications. This study was done to compare following tonsillectomy using monopolar bipolar cautery techniques our population. Methods: It a prospective, longitudinal over period of one year at Gandaki Medical College,...

OBJECTIVE Urinalysis alterations are common after prostatic surgery. However, time to normalization has not been established. Presence of pyuria and microhematuria can lead to unnecessary diagnostic procedures. The objective of this study is to determine the time to normalization for both parameters. MATERIAL AND METHODS We reviewed medical records of patients who underwent prostatic surgery ...

As the population of patients treated with deep brain stimulation (DBS) grows and the patients age, more will require routine or emergent electrophysiologic tests. DBS artifact may render these uninterpretable, whereas stopping DBS may release symptoms that confound evaluation. The authors find that monopolar, but not bipolar, stimulation produces significant artifact during EKG, EEG, and polys...

RATIONALE Despite undergoing transforaminal epidural steroid injection (TFESI), many patients complain of persisting cervical radicular pain. For the management of chronic cervical radicular pain, clinicians are widely applying pulsed radiofrequency (PRF) stimulation to dorsal root ganglions (DRGs). To enhance the effect of PRF stimulation, we conducted bipolar PRF stimulation in 2 patients wit...
