Myofascial pain syndrome (MPS) is a musculoskeletal condition characterized by regional pain and muscle tenderness associated with the presence of myofascial trigger points (MTrPs). The last decade has seen an exponential increase in the use of botulinum toxin (BTX) to treat MPS. To understand the medical evidence substantiating the role of therapeutic BTX injections and to provide useful information for the medical practitioner, we applied the principles of evidence-based medicine to the treatment for cervico-thoracic MPS. ⋯ This was due to appropriate identification of diagnostic criteria, excellent study design and objective endpoints. The 6 other identified studies had significant failings due to deficiencies in 1 or more major criteria. We conclude that higher quality, rigorously standardized studies are needed to more appropriately investigate this promising treatment modality.

Low back pain is usually self-limited. The transition from acute to chronic LBP is influenced by physical and psychological factors. Identification of all contributing factors, in a mass emergency setting, differentiating primary and secondary life-threatening forms of LBP, is the best approach for success. Aims of the present report were to estimate the prevalence of LBP in population afferent to four advanced medical presidiums (AMPs) during postseismic emergency period and to evaluate frequency of use, types of pain killers administered to patients and short-term efficacy of them. ⋯ The emotional stress induced by natural disaster tends to heighten norepinephrine and sympathetic nervous system activity, which may further amplify nociception through peripheral or central mechanisms that result in consistent prevalence of primary NSLBP and become potential risk factor for pain chronicization.

Review Meta Analysis
Systematic Review and Meta-Analysis of Pharmacological Therapies for Painful Diabetic Peripheral Neuropathy.
Painful diabetic peripheral neuropathy (pDPN) is prevalent among persons with diabetes and increases over time. Published guidelines recommend a number of medications to treat this condition providing clinicians with a variety of treatment options. This study provides a comprehensive systematic review and meta-analysis of published pharmacologic therapies for pDPN. ⋯ Selecting an appropriate pDPN therapy is key given the large number of available treatments. Comparative results revealed relative equivalence among many of the studied interventions having the largest overall sample sizes and highlight the importance of standardization of methods to effectively assess pain.

Case Reports
Neuropathic Pain with Features of Complex Regional Syndrome in the Upper Extremity after Herpes Zoster.
We report a case of a 73-year-old female who developed unbearable neuropathic pain after a herpes zoster episode. The pain persisted and could not be controlled despite multimodal analgesia. In addition to postherpetic neuralgia, myelitis and complex regional pain syndrome were diagnosed during the evolution of neuropathic pain. This complex neuropathic pain was resolved after sympathetic ganglion block.

Healthcare resource utilization (HCRU) and associated costs specific to pain are a growing concern, as increasing dollar amounts are spent on pain-related conditions. Understanding which pain conditions drive the highest utilization and cost burden to the healthcare system would enable providers and payers to better target conditions to manage pain adequately and efficiently. The current study focused on 36 noncancer chronic and 14 noncancer acute pain conditions and measured the HCRU and costs per member over 365 days. ⋯ The conditions ranked highest for both per-member and total healthcare costs were hip fractures, childbirth, and non-hip, non-spine fractures. Among these, hip fractures in the Medicare member population had the highest mean cost per member (adjusted per-member cost was $21,058). Further examination specific to how pain is managed in these high-cost conditions will enable providers and payers to develop strategies to improve patient outcomes through appropriate pain management.
