Neuropathic pain is a serious chronic condition strongly affecting quality of life, which can be relieved but cannot be cured. Apart from symptomatic management, treatment should focus on the underlying disorder. The estimated prevalence is at least 1% to 5% of the general population. ⋯ Ancillary investigations may include EMG and computerized tomography/magnetic resonance imaging scans, depending on the localization of the suspected lesion. A limited number of agents, primarily directed at symptom control, are currently approved for use in neuropathic pain. A mechanism-based approach to pharmacological intervention supports the use of polypharmacy in neuropathic pain.

Comparative Study Observational Study
The Comparison of Two Analgesic Regimes after Ambulatory Surgery: An Observational Study.
Over the past 15 years, the number of ambulatory surgical procedures worldwide has increased continuously. Studies show that 30% to 40% of the patients experience moderate-to-severe pain in the first 48 hours. The objective of this observational study is to compare the percentage of moderate-to-severe pain, side effects, and the use of escape medication of two different analgesic regimes after ambulatory surgery. ⋯ A total of 375 patients participated in the study, of which 99 in the tramadol group and 138 in the combination tablet tramadol/paracetamol group. The percentage of patients with moderate-to-severe postoperative pain was 25% to 40%. In both the groups, an equal percentage of patients experienced moderate-to-severe postoperative pain. Both analgesic regimes have a comparable analgesic effectiveness with each with its own specific advantages and disadvantages. On the first day after surgery, patients with the tramadol/paracetamol regime experienced more side effects (drowsiness and nausea) were less therapy compliant, but needed a smaller amount of escape medication than the patients from the tramadol group.

Clinical Trial
Percutaneous Nerve Stimulation in Chronic Neuropathic Pain Patients due to Spinal Cord Injury: A Pilot Study.
The long-term prognosis for neuropathic pain resolution following spinal cord injury (SCI) is often poor. In many SCI patients, neuropathic pain continues or even worsens over time. Thus, new treatment approaches are needed. We conducted a pilot study to evaluate the feasibility and effect of percutaneous (electrical) nerve stimulation (P(E)NS) in SCI patients with chronic neuropathic pain. ⋯ P(E)NS is feasible as an intervention in SCI patients and might have a positive effect on pain reduction in a part of this patient group.

The cold pressor task (CPT) was originally developed as a clinically indicative cardiovascular test, and quantifies vascular response and pulse excitability when a subject's hand is immersed into ice water. Since the test procedure results in a gradually increasing cold pain, the CPT has been widely used as a nociceptive stimulus in experimental studies on adults and children. ⋯ Consistent with previous findings, regression analysis reveals that age is significantly associated with pain tolerance. The CPT procedure shows excellent 2 week test-retest stability to assess pain threshold and pain tolerance within a student population.

Patient satisfaction is tied to outcome, but there is scant literature on the relationship of patient perceived outcome and attributes of the pain clinic visit, including the patient interaction with the pain management specialist. The primary purpose of this study is to identify attributes of the patient-provider interaction most strongly associated with patient perceived outcome of their clinic visit. The secondary aim is to correlate patient perceived outcome with patient self-rated overall health. ⋯ Our results suggest that pain physicians may positively impact patient perceived outcomes of clinic visits by explaining the patient's condition and treatment, providing instructions, and taking the time to understand the patient and their values.
