To present three identified novel COL2A1 mutations causing spondyloepiphyseal dysplasia congenita (SEDC) in three unrelated Chinese families, and perform analysis regarding the clinical and genetic features of SEDC in the Chinese population through assessment of the literature. ⋯ Our study contributed to the further expansion of the COL2A1 mutation spectrum and provided more information concerning SEDC in the Chinese population through literature review.

To investigate the factors related to the 1-month period prevalence of low back pain (LBP), neck pain (NP) and thoracic spine pain (TSP) in young adolescents, thereby considering potential correlates from the physical, sociodemographic, lifestyle, psychosocial and comorbid pain domains. ⋯ Psychosomatic symptoms and pain comorbidities had the strongest association with 1-month period prevalence of spinal pain in young adolescents, followed by factors from the physical and psychosocial domains. The role that "physical factors" play in non-adult spinal pain may have been underestimated by previous studies.

To clarify the significance of Modic changes, bony endplate lesions, and disc degeneration as predictors of chronic low back pain (LBP) during 1-year follow-up. ⋯ In patients with chronic non-specific LBP, persisting M1, decreasing disc height, and increasing bony endplate lesions associated with persisting pain while decrease of SI of the disc with decrease of pain. Such changing MRI findings in the same disc space have earlier been shown to progress abnormally fast. They may be signs or biomarkers of a prolonged pain causing, deforming degenerative process, and should lead to considering early intervention or specific treatments to affect that process.

Grading inter-vertebral disc degeneration (IDD) is important in the evaluation of many degenerative conditions, including patients with low back pain. Magnetic resonance imaging (MRI) is considered the best imaging instrument to evaluate IDD. The Pfirrmann classification is commonly used to grade IDD; the authors describing this classification showed an adequate agreement using it; however, there has been a paucity of independent agreement studies using this grading system. The aim of this study was to perform an independent inter- and intra-observer agreement study using the Pfirrmann classification. ⋯ In this independent study, the Pfirrmann classification demonstrated an adequate agreement among different observers and by the same observer on separate occasions. Furthermore, it allows communication between radiologists and spine surgeons.
