Randomized Controlled Trial
Arginine Vasopressin and Arginine Vasopressin Receptor 1b Involved in Electroacupuncture-Attenuated Hypothalamic-Pituitary-Adrenal Axis Hyperactivity in Hepatectomy Rats.
The study aims to know the effect of electroacupuncture (EA) in maintenance of the homeostasis of the neuroendocrine system in hepatectomy rats and the involvement of arginine vasopressin (AVP) signaling in hypothalamus after EA was observed. ⋯ EA application at ST36 and SP6 can ameliorate the hyperactivity of the HPA axis via AVP signaling during the perioperative period.

Deep brain stimulation (DBS) is widely used for various movement disorders. DBS lead revisions are becoming more common as the indications and number of cases increases. ⋯ Surgical technique, as well as variable options are important in lead revision and can be dictated based on reason for revision. Over time patients who have had adequate relief with DBS placement may experience loss of efficacy and development of adverse effects requiring revision of the DBS lead to maintain its effects.

The speed of intrathecal drug administration (slow continuous infusion vs. rapid bolus application) might influence the efficacy of therapy despite the equal daily dose in both administration patterns. We tested this hypothesis in a small prospective single-centre pilot study in a population of chronic pain patients with intrathecal opioid therapy. ⋯ Intermittent bolus administration may be helpful for increasing the efficacy of intrathecal opioid therapy of chronic pain.

Spinal cord stimulation (SCS) is used for treating intractable neuropathic pain. It has been suggested that burst SCS (five pulses at 500 Hz, delivered 40 times per second) suppresses neuropathic pain at least as well as conventional tonic SCS, but without evoking paraesthesia. The efficacy of paraesthesia-free high and low amplitude burst SCS for the treatment of neuropathic pain in patients who are already familiar with tonic SCS was evaluated. ⋯ Burst stimulation is in general more effective than tonic stimulation. Individual patients can highly benefit from burst stimulation; however, the therapeutic range of burst stimulation amplitudes requires individual assessment.

The study aims to assess utilization of spinal cord stimulator (SCS) devices while driving a vehicle and potential association with motor vehicle accidents (MVAs). ⋯ Because of the perceived benefits of pain reduction, there is high utilization of active SCS while driving a motor vehicle and that does not seem predispose toward MVAs.
