Randomized Controlled Trial Comparative Study
Comparative efficacy of levobupivacaine and ropivacaine for epidural block in outpatients with degenerative spinal disease.
Levobupivacaine has less toxic potential on both the cardiovascular and central nervous system and has been widely used for postoperative epidural analgesia in surgical patients. However, there are few reports on the efficacy of epidural levobupivacaine in outpatients with lumbosacral radiculopathy. This study was carried out to evaluate the comparative efficacy of levobupivacaine and ropivacaine for epidural block in outpatients with degenerative spinal disease and sciatica. ⋯ The results showed that 0.125% levobupivacaine and 0.2% ropivacaine for epidural block by a caudal approach provide similar lumbosacral pain relief, hemodynamic effects, and the degree and the recovery of motor blockade in outpatients with degenerative spinal disease and sciatica.

The clinical application of pulsed radiofrequency (PRF) by interventional pain physicians for a variety of chronic pain syndromes, including occipital neuralgia, is growing. As a minimally invasive percutaneous technique with none to minimal neurodestruction and a favorable side effect profile, use of PRF as an interventional neuromodulatory chronic pain treatment is appealing. Occipital neuralgia, also known as Arnold's neuralgia, is defined by the International Headache Society as a paroxysmal, shooting or stabbing pain in the greater, lesser, and/or third occipital nerve distributions. Pain intensity is often severe and debilitating, with an associated negative impact upon quality of life and function. Most cases of occipital neuralgia are idiopathic, with no clearly identifiable structural etiology. Treatment of occipital neuralgia poses inherent challenges as no criterion standard exists. Initially, conservative treatment options such as physical therapy and pharmacotherapy are routinely trialed. When occipital neuralgia is refractory to conservative measures, a number of interventional treatment options exist, including: local occipital nerve anesthetic and corticosteroid infiltration, botulinum toxin A injection, occipital nerve subcutaneous neurostimulation, and occipital nerve PRF. Of these, PRF has garnered significant interest as a potentially superior, safe, non-invasive treatment with long-term efficacy. ⋯ Clinical studies to date examining the efficacy of PRF as a treatment for occipital neuralgia have yielded promising results, demonstrating sustained improvement in pain, quality of life, and adjuvant pain medication usage. Despite these encouraging clinical studies, conclusive evidence in support of PRF as an interventional treatment option for occipital neuralgia awaits to be seen.

Ice hockey is a competitive sport and ice hockey injuries can be influenced by many physical and psychological factors. Young ice hockey players are especially vulnerable to injury due to their relative lack of experience and rapid physical growth during their juvenile years. Up to now there has been no survey of the physical, psychological, and environmental etiological factors based on the Korean high school ice hockey players population. ⋯ The multiple aspects of this etiological factor analysis showed modest results. However, based on our results, in order to reduce the long-term implications of youth ice hockey injuries and associated public health costs, comprehensive efforts, including psychological and environmental factor modification, should be put in place.

We report a new technique for pulsed radiofrequency (PRF) of the entire nerve supply of the knee as an option in treating osteoarthritis (OA) of knee. We targeted both sensory and motor nerves supplying all the structures around the knee: joint, muscles, and skin to address the entire nociception and stiffness leading to peripheral and central sensitization in osteoarthritis. Ten patients with pain, stiffness, and loss of function in both knees were treated with ultrasonography (USG) guided PRF of saphenous, tibial, and common peroneal nerves along with subsartorial, peripatellar, and popliteal plexuses. ⋯ The sustained pain relief and muscle relaxation enabled the patients to optimize physiotherapy thereby improving endurance training to include the daily activities of life. We conclude that OA knee pain is a product of neuromyopathy and that PRF of the sensory and motor nerves appeared to be a safe, effective, and minimally invasive technique. The reduction of pain and stiffness improved the knee function and probably reduced the peripheral and central sensitization.
