The Dutch clinical practice guideline on the diagnosis and management of pain in patients with cancer was published in 2008 and intensively promoted to healthcare professionals who see patients with cancer. One of the most important recommendations is the systematic registering of the pain and its intensity. To evaluate in which degree this part of the practice guideline is implemented, we analyzed the medical records of patients attending the outpatient oncological clinic in an academic hospital, a large teaching hospital, and 4 smaller peripheral hospitals. ⋯ There may be several reasons for the difference in reporting rate of pain in patients with cancer. Our findings indicate that the clinical practice guideline with regard to pain registration is poorly implemented in oncology outpatient clinics. More efforts should be made to generate the awareness for the need of pain registration.

The important pathophysiologic factor of neurogenic intermittent claudication (NIC) in lumbar spinal canal stenosis (LSCS) has been reported to be the reduction in intraneural blood flow and a state of relative ischemia in nerve tissues. Prostaglandin E1 (PGE1) presumably improves symptoms in patients with LSCS by improving the blood flow in the cauda equina and nerve roots through its vasodilation and antiplatelet aggregation effects. The purpose of the study was to summarize the results of previous studies regarding PGE1 treatment for LSCS and to describe the details of PGE1 treatment to all physicians who take care of patients with LSCS. ⋯ Based on the results of previous studies, PGE1 treatment may be an option as a conservative treatment for LSCS. However, future studies with high-quality and long-term follow-up are necessary. Future studies also should include refinement of indications, administration period, as well as comparisons between PGE1 treatment and other conservative treatments such as epidural injection.

The patient health questionnaire (PHQ) is designed for screening psychopathology in primary care settings. However, little is known about its clinical utility in other chronic pain populations, which usually have high psychiatric comorbidities. ⋯ The strong specificity of the PHQ appears to be its primary strength for this cohort. Due to its high specificity, the PHQ could be employed as an additional screening tool to help rule out potential psychiatric comorbidity in patients with CDOMD. The low sensitivity of the PHQ in this population, however, remains a weakness of the PHQ.

The aim of the this study was to investigate the combined effects of heterosegmental non-noxious and noxious stimulation on electrically induced tooth pain. The late component of somatosensory-evoked potentials (SEP), induced by electrical tooth stimulation and pain intensity, were examined under electrical stimulation to forearms. Noxious, non-noxious, and combined non-noxious and noxious electrical stimulation were applied to median nerves on the forearms. ⋯ The amplitudes of the SEP and VAS scores in the combined stimulation session decreased significantly compared with those in the control session and the reduction rates were 51.1% (13.4 μV) and 41.0% (23.5 mm), respectively. These results show that the combined stimulation has a more potent analgesic effect than that of either the non-noxious or the noxious stimulation. It is suggested that a potent analgesia was produced by an activated central mechanism, including endogenous opioid and descending pain inhibitory systems due to combined non-noxious and noxious stimulation.

Coblation of Femoral and Sciatic Nerve for Stump Pain and Phantom Limb Pain: A Case Report.
There is currently no reliable treatment for stump pain and phantom limb pain. Peripheral factors play a significant role in the pathophysiology of stump pain and phantom limb pain. Coblation technology is a relatively new technology that has shown promise in treating neuropathic pain. ⋯ Our report suggests that coblation technology may be useful treatment for stump pain and phantom limb pain. Treatments focusing on peripheral nerves may be more effective than those focusing on the neuroma. This finding needs additional study for confirmation.
