Observational Study
Assessment of neuropathic pain in patients with cancer: the interobserver reliability. An observational study in daily practice.
Neuropathic pain (NeP) is a burdensome problem in all stages of cancer. Although clinical judgment is accepted as a surrogate for an objective gold standard in diagnosing NeP, no publications were found about its reliability. ⋯ A substantial level of agreement was found for the diagnosis of pure NeP and a moderate level of agreement for the diagnosis of the NeP component was found, both with a PA = 70%. There was only a fair agreement between the physicians regarding the grading system. However, there was a substantial level of (interrater) agreement for the diagnosis of an NeP component and the outcome of the grading system. The findings in this study also suggest that a better standardization of the clinical assessment and classification of pain in patients with cancer with respect to the identification of neuropathic pain is necessary.

Pudendal nerve entrapment (PNE) is an uncommon cause of chronic pain. Pudendal nerve entrapment typically occurs when the pudendal nerve is fused to nearby anatomical structures or trapped between the sacrotuberous and sacrospinalis ligaments. Pudendal nerve entrapment can be caused by excessive bicycling, pregnancy, anatomic abnormalities, scarring due to surgery, or as a sequela of radiation therapy. ⋯ He was ultimately diagnosed as having a right sided pudendal entrapment neuropathy. His pain was refractory to all conventional treatment modalities; therefore we decided to pursue neuromodulation via a dorsal column spinal cord stimulator implant. Below, we describe the decision making process for the diagnosis and treatment of his pudendal neuropathy.

Comparative Study
Percutaneous endoscopic lumbar discectomy for L5-S1 disc herniation: transforaminal versus interlaminar approach.
Percutaneous endoscopic lumbar discectomy (PELD) is a minimally invasive spinal technique. The unique anatomic features of the L5-S1 space include a large facet joint, narrow foramen, small disc space, and a wide interlaminar space. PELD can be performed via 2 routes, transforaminal (TF-PELD) or interlaminar (IL-PELD). However, it is questionable that the decision of the endoscopic route for L5-S1 discs only depends on the surgeon's preference and anatomic relation between iliac bone and disc space. Thus far, no study has compared TF-PELD with IL-PELD for L5-S1 disc herniation. ⋯ This study demonstrated that TF-PELD is preferred for shoulder type, centrally located, and recurrent disc herniation, while IL-PELD is preferred for axillary type and migrated discs, especially those of a high grade.

Comparative Study
A comparison of chronic pain prevalence in Japan, Thailand, and myanmar.
Pain has been regarded as important in the improvement of quality of life (QOL). In the advanced countries of Europe and the North America, a number of large-scale epidemiological surveys on pain, particularly chronic pain, have thus been performed in general populations. However, few epidemiological surveys of chronic pain have been reported from developing countries, and no surveys appear to have examined chronic pain in the least developed countries. ⋯ The prevalence of chronic pain was significantly lower in Myanmar than in Japan or Thailand. With regard to the site and treatment of chronic pain, no clear tendencies were observed between countries, suggesting that frequency and the character of chronic pain differ from country to country around the world.

In more and more countries, a specific pain education curriculum is provided to instruct pain physicians. However, there is little literature on pain education and in particularly how to evaluate their knowledge. One of the modules interesting to assess is the use of clinical practice guidelines (CPGs) by pain physicians. ⋯ Case vignette is an interesting instrument for pain education because it is cheap, easy to use, and can be repeated. However, training before using this instrument is needed for pain physicians, in particular during their pain education.
