Objective Ganglion impar block (GIB) can be performed in patients with chronic coccygodynia who do not respond to conservative treatments. We investigated the effect of coccygeal dynamic patterns on the treatment outcome in patients with chronic coccygodynia treated with GIB. Materials and methods We retrospectively analyzed the data for patients diagnosed with chronic coccygodynia who underwent GIB only once by a transsacrococcygeal method under fluoroscopy guidance in our Pain Medicine Clinic. ⋯ Significant pain relief was achieved in 42.9% and 61.9% of patients in Group I and II at the last examination, respectively. Conclusion GIB administered by transsacrococcygeal method in patients with chronic coccygodynia is a safe and alternative treatment approach with reduced pain scores and low complication rates. In patients with chronic coccygodynia, having a normal or immobile coccyx does not appear to affect treatment outcomes.

Discogenic low back pain (DLBP) is extremely common and costly. Effective treatments are lacking due to DLBP's unknown pathogenesis. Currently, there are no in vivo mouse models of DLBP, which restricts research in this field. ⋯ Disc-puncture also produced an upregulation of neuropeptides in dorsal root ganglia neurons and an activation of glial cells in the spinal cord dorsal horn. These findings indicate that the cellular and structural changes in discs, as well as peripheral and central nervous system plasticity, paralleled persistent, and robust behavioral pain responses. Therefore, this mouse DLBP model could be used to investigate mechanisms underlying discogenic pain, thereby facilitating effective drug screening and development of treatments for DLBP.

Low back pain (LBP) is the symptom of a group of syndromes with heterogeneous underlying mechanisms and molecular pathologies, making treatment selection and patient prognosis very challenging. Moreover, symptoms and prognosis of LBP are influenced by age, gender, occupation, habits, and psychological factors. LBP may be characterized by an underlying inflammatory process. Previous studies indicated a connection between inflammatory response and total plasma N-glycosylation. We wanted to identify potential changes in total plasma N-glycosylation pattern connected with chronic low back pain (CLBP), which could give an insight into the pathogenic mechanisms of the disease. ⋯ To our knowledge, this is a first large clinical study on CLBP patients and plasma N-glycome providing a new glycomics perspective on potential disease pathology.
