With interest, we read the article from Simopoulos et al (1). We have extensively utilized pulsed radiofrequency applications for radicular pain for greater than 10 years. As published earlier (1), it is our experience that outcome is directly related to the proximity of the radiofrequency electrode to the targeted neural structure. Thus, positive stimulation at 50 Hz at less than 0.2 volts wou...

Dear Editor, Glossopharyngeal neuralgia (GPN) is an uncommon cause of facial pain with a crude incidence rate estimated to be 0.7 per 100,000 yearly.1 GPN incidence is only 0.2% to 1.3% that of the more known facial pain entity trigeminal neuralgia.2 The character and distribution of pain is often diagnostic; shooting from the pharynx, tonsil, and posterior base of tongue upwards to the Eustach...

The coexistence of median and cervical nerve root damage might hide a complex pathophysiology. Here, we describe and discuss the case of a patient suffering from numbness and painful tingling of the hand, whose symptoms were effectively treated with pulsed radiofrequency and epidural administration of bupivacaine and morphine.

Nanosecond pulsed electric fields are emerging as a new modality for tissue and tumor ablation. We previously reported that cells exposed to pulsed electric fields develop hypersensitivity to subsequent pulsed electric field applications. This phenomenon, named electrosensitization, is evoked by splitting the pulsed electric field treatment in fractions (split-dose treatments) and causes in vit...

Facial acne vulgaris with post-inflammatory erythema is one of the most common problems encountered in dermatologic clinics. It can leave hypertrophic scars and cause psychological problems. Thus, effective therapeutic interventions are needed. The aim this study was to evaluate efficacy safety a pulsed-type bipolar radiofrequency (RF) device for treating erythema. Eighteen patients who had bee...

This study compared the efficacy of continuous or pulsed-water medication with enrofloxacin, danofloxacin, and sarafloxacin in eight groups of 90 chicks each by using an infectious bronchitis virus-Escherichia coli model of colisepticemia. The model produced lesions of typical those occurring in birds with severe colisepticemia; for the infected, nonmedicated birds the mortality was 43.5% and t...

The stellate ganglion is a common target to manage neuropathic pain in the upper extremities. However, the effect duration of a single stellate ganglion block is often temporary. To overcome the short-term effects of a single sympathetic block, pulsed radiofrequency (PRF) can be applied. The aim of the present study was to investigate the efficacy of PRF on the cervical sympathetic chain under ...

Hemifacial spasm is defined as unilateral, involuntary, irregular twitching of all or parts of the muscles innervated by facial nerves. Here, we present a case of recurrent hemifacial spasm after microvascular decompression (MVD) treated with pulsed radiofrequency (PRF) treatment with good results. A 35-year-old woman suffered from recurrent hemifacial spasm after MVD that was refractory to med...

OBJECTIVE To evaluate the safety and effectiveness of different bipolar radiofrequency system algorithms in interrupting the renal sympathetic nerves and reducing renal norepinephrine in a healthy porcine model. METHODS A porcine model (N = 46) was used to investigate renal norepinephrine levels and changes to renal artery tissues and nerves following percutaneous renal denervation with radio...
