Chronic pain is an important public health problem, and there is a need to understand the mechanisms that lead to pain chronification. From a neurobiological perspective, the mechanisms contributing to the transition from acute to subacute and chronic pain are heterogeneous and are thought to take place at various levels of the peripheral and central nervous system. ⋯ This review summarizes important and recent findings in pain research using magnetic resonance tomography. Especially new developments in functional, structural and neurochemical imaging such as resting-state connectivity and γ-aminobutyric acid (GABA) spectroscopy, which have advanced our understanding of chronic pain and which can potentially be integrated in clinical practice, will be discussed.

Review"Real-life" treatment of chronic pain: Targets and goals.
Treating chronic pain is a complex challenge. While textbooks and medical education classically categorize pain as originating from peripheral (nociceptive), neuropathic, or centralized origins, in real life each and every patient may present a combination of various pain sources, types, and mechanisms. ⋯ Failing to recognize the coexistence of different types of pain in an individual patient and escalating medications only on the basis of total pain intensity are liable to lead to both ineffective control of pain and increased untoward effects. In the current review, we outline strategies for deconstructing complex pain and therapeutic suggestions.

ReviewUpdate on the genetics of the fibromyalgia syndrome.
Fibromyalgia syndrome (FMS), a condition characterized by chronic widespread pain and tenderness, is a complex condition considered to represent a paradigm of centralized pain. FMS has demonstrated a clear familial aggregation, and hence it is considered to have a genetic background. ⋯ In addition, genome-wide sequencing scanning (genome-wide association study (GWAS)) is increasingly being harnessed for the study of chronic pain, including FMS. Micro RNAs are another novel field of research related to posttranscriptional inhibition of gene expression, which are currently regarding the pathogenesis of FMS.

ReviewBurden of disability due to musculoskeletal (MSK) disorders.
This chapter summarises the global and regional prevalence, disability (Years Lived with Disability (YLDs)) and overall burden (Disability Adjusted Life Years (DALYs)) and costs for the common musculoskeletal disorders including low back and neck pain, hip and knee osteoarthritis, rheumatoid arthritis, gout, and a remaining combined group of other MSK conditions. The contribution of the role of pain in disability burden is introduced. Trends over time and predictions of increasing MSK disability with demographic changes are addressed and the particular challenges facing the developing world are highlighted.

ReviewOverview of neurodevelopment and pain research, possible treatment targets.
Pain is a common presenting and often persistent symptom for children with rheumatological disease. Pain is not clearly related to disease severity in children with inflammatory juvenile idiopathic arthritis, and presentations of non-inflammatory musculoskeletal pain are common but there is limited evidence to guide management. ⋯ Genotyping, sensory evaluation and neuroimaging may better characterize chronic musculoskeletal pain, identify high-risk groups and/or provide additional outcome measures to monitor disease and treatment progress. An integrated approach to management is required to effectively select and target interventions, reduce pain and disability and improve long-term outcome.
