The aim of this study was to a) evaluate the time between onset of occipital neuralgia symptoms and nerve decompression surgery, b) perform a cost comparison analysis between surgical and non-surgical treatment of occipital neuralgia and c) report postoperative results of nerve decompression for occipital neuralgia. ⋯ Weill Cornell Medicine: 23-04025985, Prospective Cohort Study Investigating Long- Term Outcomes After Headache Surgery.The Massachusetts General Hospital: 2012P001527, Correlation of pre-operative pain self-efficacy and post-operative migraine-specific symptoms and disability.

A potentially useful biomarker for Complex Regional Pain Syndrome (CRPS) is the serum soluble interleukin-2 receptor (sIL-2R) level, which is a marker for T-cell activation. Elevated serum sIL-2R levels have been described in CRPS patients compared to healthy controls. In T-cell mediated inflammatory diseases such as sarcoidosis and rheumatoid arthritis, the serum sIL-2R levels correlate with disease severity. In this study, we investigate whether an association exists between serum sIL-2R levels in CRPS patients and CRPS severity. ⋯ Our findings suggest that serum sIL-2R levels cannot be used as a biomarker for syndrome severity in persistent CRPS (syndrome duration >1 year). Serial measurements of serum sIL-2R from early CRPS to persistent CRPS are needed to investigate whether serum sIL-2R levels can be used to monitor T-cell mediated inflammatory syndrome activity.

The Mediating Effect of Social Functioning on the Relationship between Catastrophizing and Pain among Patients with Chronic Low Back Pain.
Pain catastrophizing can be characterized as an interpersonal form of coping used to elicit support or empathy from others. Despite intentions of increasing support, catastrophizing can impair social functioning. While considerable work has addressed the relationship between catastrophizing and pain, limited empirical work has examined this relationship within a social context. First, we examined the role of catastrophizing as a potential contributor to group differences (chronic low back pain [cLBP] vs pain-free controls) in social functioning. Then we conducted a follow-up, exploratory analysis to examine the relationships between catastrophizing, social functioning, and pain within the subgroup of participants with cLBP. ⋯ We showed that impaired social functioning was driving the relationship between higher pain catastrophizing and worse pain among participants with cLBP. Interventions, such as cognitive behavioral therapy, should address catastrophizing in individuals with cLBP, while simultaneously improving social functioning.

Presurgical sleep and pain behaviors predict insomnia symptoms and pain after total knee arthroplasty: A 12-Month Longitudinal, Observational Study.
Up to 40% of individuals who undergo total knee arthroplasty (TKA) experience some degree of pain following surgery. Presurgical insomnia has been identified as a predictor of postsurgical pain; however, modifiable presurgical behaviors related to insomnia have received minimal attention. The objective of the present study was to develop a 2-item sleep and pain behavior scale (SP2) to investigate a maladaptive sleep and pain behavior and is a secondary analysis of a larger, parent study. ⋯ This provides preliminary evidence that patients who cope with pain by retiring to their bed and bedroom have higher rates of post-surgical insomnia and pain and supports efforts to target this maladaptive sleep and pain behavior to reduce postsurgical pain.
