Interpatient variability is frequently observed among individuals with chronic low back pain (cLBP). This review aimed at identifying phenotypic domains and characteristics that account for interpatient variability in cLBP. We searched MEDLINE ALL (through Ovid), Embase Classic and EMBASE (through Ovid), Scopus, and CINAHL Complete (through EBSCOhost) databases. ⋯ Despite these findings, our review showed that the evidence on pain phenotyping still requires further investigation. The assessment of the methodological quality revealed several limitations. We recommend adopting a standard methodology to enhance the generalizability of the results and the implementation of a comprehensive and feasible assessment framework to facilitate personalized treatments in clinical settings.

Multicenter Study
[Validation of the German version of the Fear-Avoidance Beliefs Questionnaire (FABQ-D) for shoulder disorders].
With a prevalence of up to 30%, shoulder disorders form the third largest group of musculoskeletal complaints worldwide. Their formation and development are influenced by psychosocial factors such as movement-related fear. One of the internationally most common measurements for quantifying fear of movement is the Fear-Avoidance Beliefs Questionnaire (FABQ). ⋯ The FABQ‑D is a reliable measurement tool. The construct validity should be further investigated in future studies. This study reproduced results from previous studies in other populations. The FABQ‑D appears to be an adequate measurement tool for quantifying fear of movement in patients with shoulder disorders.

Primary systemic amyloidosis is a systemic disease characterised by the deposition of misfolded proteins extracellularly in different organs without any known cause in the background, eventually leading to multiorgan dysfunction and death. The incidence of primary amyloidosis is estimated at 5.1-12.8 cases per million, with a poor prognosis. We report a case of a 69-year male with lower back pain, shortness of breath, and anasarca diagnosed as primary systemic amyloidosis by serum-free light chain assay and kidney needle biopsy. He was started on intravenous bortezomib and dexamethasone. Though he adhered to his medications, with time he developed renal insufficiency marked by azotemia following which hemodialysis was performed. Primary systemic amyloidosis is a rare clinical condition with a very poor prognosis. Further studies are needed to understand the proper pathophysiology and treatment of the disease. ⋯ cardiomyopathies; case reports; primary amyloidosis.

We conducted a bidirectional Mendelian randomization study to examine the causal effects of six personality traits (anxiety, neuroticism, extraversion, openness to experience, agreeableness, and conscientiousness) on back pain associated with health care use and the causal effect of back pain on the same risk factors. Genetic instruments for the personality traits and back pain were obtained from the largest published genome-wide association studies conducted in individuals of European ancestry. We used inverse weighted variance meta-analysis and Causal Analysis Using Summary Effect for primary analyses and sensitivity analyses to examine evidence for causal associations. ⋯ We found evidence for statistically significant bidirectional causal associations between neuroticism and back pain, with odds ratio 1.51 (95% confidence interval 1.37; 1.67) of back pain per neuroticism sum score standard deviation, P-value = 7.80e-16; and beta = .12, se = .04 of neuroticism sum score standard deviation per log odds of back pain, P-value = 2.48e-03. Other relationships did not meet our predefined criteria for causal association. PERSPECTIVE: The significant positive feedback loop between neuroticism and back pain highlights the importance of considering neuroticism in the management of patients with back pain.
