The purpose of this study was to determine the intermediate clinical and radiographic outcomes of Bryan Cervical Disc (Medtronic Sofamor Danek, Inc, Memphis, Tennessee) replacement for the treatment of cervical degenerative disk disease and its effect on adjacent levels. Between November 2004 and December 2007, thirty-four patients (38 disks) underwent Bryan Cervical Disc replacement in the authors' hospital. The authors retrospectively analyzed the records of 32 patients who completed follow-up. ⋯ Prosthesis-related complications were rare, and no reoperations were performed. Bryan Cervical Disc replacement achieves satisfactory mid-term clinical and radiographic outcomes. The authors observed the progression of adjacent segment degeneration postoperatively, although no degradation of clinical outcomes occurred.

Translation, adaptation and validation of the Moroccan version of the Quebec Back Pain Disability Scale.
This study aims to translate and cross-culturally adapt the Moroccan version of the Quebec Back Pain Disability Scale (QDS) and to investigate its reliability and validity in Moroccan patients with low back pain (LBP). The translation and cross-cultural adaptation of the QDS were developed in agreement with published guidelines. The QDS was translated by use of the forward and backward translation procedure. ⋯ The correlation between QDS and RMDQ was very good (r = 0.664; p ≤ 0.001). There was no correlation between QDS and the other variables. Accordingly, the Moroccan version of QDS has good reproducibility, internal consistency and validity for the assessment of disability in Moroccan-speaking patients with LBP.

Epidural steroid injection has been frequently performed to treat chronic pain due to lumbosacral disc herniation (L-HIVD). However, a considerable number of patients do not achieve pain relief using this method because perineural or epidural adhesions prevent the spread of injectate into the epidural space. Percutaneous adhesiolysis (PA) is thought to be a useful method because it can eliminate the deleterious effects of adhesion. ⋯ PA with NaviCath® showed clinical effectiveness in the treatment of chronic pain due to L-HIVD that was not responsive to transforaminal epidural injection. Previous surgery and the presence of spinal stenosis or spondylolisthesis were poor prognostic predictors. This procedure may enable the physician to place the catheter tip and deliver medicine more precisely.

Considerable evidence demonstrates substantial ethnic disparities in the prevalence, treatment, progression and outcomes of pain-related conditions. Elucidating the mechanisms underlying these group differences is of crucial importance in reducing and eliminating disparities in the pain experience. ⋯ These diverse factors, and others may all play a role in facilitating elevated levels of pain-related suffering among individuals from ethnic minority backgrounds. Here, we present a brief, nonexhaustive review of the recent literature and potential physiological and sociocultural mechanisms underlying these ethnic group disparities in pain outcomes.
