Adolescent cervical disc degeneration in MRI does not predict adult headache or neck pain: A 5-year follow-up of adolescents with and without headache

A scoping review of chronic pain in emerging adults

Much of the adult chronic pain literature addresses pain in typical pain cohorts of middle-aged to older individuals. To date, little research has focused on chronic pain in younger adults, who likely have a completely different pain experience. This scoping review aimed to address this gap by describing the emerging adult (18-29 years) chronic pain experience regarding prevalence, associated factors, outcomes, and pain management. Searches of primary electronic databases including PubMed, Embase, PsycINFO, and CINAHL were performed on February 26, 2020, restricting the publication date from database inception to December 31, 2019. The search strategy, conducted in English, covered search term combinations of "chronic pain" and "young adults." A total of 6,612 records were considered-3,141 after removing duplicates. These records were screened by title and abstract; 871 through full-text screening. Of these, 78 articles covered the topic of emerging adults with chronic pain. Collectively, results indicated that between 5% and 30% of emerging adults experience chronic pain, depending on the sample and exact chronic pain definition. The most consistent associated factors were female sex, familial chronic pain, and previous experiences of chronic pain in childhood. Anxiety, depression, and sleep issues appeared associated both before and after the onset of chronic pain. Outcomes of pain included interruptions to study and work, poorer physical functioning, and pain-related interference to socializing. We observed that few pain treatments have been tested specifically in this cohort. A greater ongoing focus on chronic pain in emerging adults is required to improve long-lasting outcomes.

Do findings identified on magnetic resonance imaging predict future neck pain? A systematic review

BACKGROUND CONTEXT

Magnetic resonance imaging (MRI) has the potential to identify pathology contributing to neck pain. However, the importance of findings on MRI remains unclear.

PURPOSE

We aimed to investigate whether findings on cervical spine MRI predict future neck pain.

STUDY DESIGN

A systematic review was carried out.

PATIENT SAMPLE

People with or without neck pain comprised the study sample.

OUTCOME MEASURES

Clinically important neck pain outcomes such as pain and disability.

METHODS

The review protocol was registered on PROSPERO [CRD42016049228]. MEDLINE, CINAHL, and EMBASE databases were searched. Prospective cohort studies investigating the association between baseline MRI findings and clinical outcome were included. Cohorts with serious underlying diseases as the cause of their neck pain were excluded. Associations between MRI findings and neck pain outcomes were extracted from the included studies.

RESULTS

A total of 12 studies met all inclusion criteria. Eight studies presented data on participants with current neck pain, two studies included a mixed sample, and two studies included a sample of participants with no current neck pain. Because of the heterogeneity between the studies in terms of MRI findings, populations, and clinical outcomes investigated, it was not possible to pool the results. No consistent associations between MRI findings and future outcomes were identified. Single studies of populations with neck pain reported significant associations for neck muscle fatty infiltrate (risk ratio [RR]: 21.00, 95% confidence interval [CI]: 2.97-148.31) with persistent neck disability; disc protrusion (mean difference ranged from -1.83 to -2.88 on a 10-point pain scale), and disc degeneration (RR: 0.59; 95% CI: 0.36-0.98) with neck pain. In a population without pain, the development of foraminal stenosis over a 10-year period was associated with development of neck pain (RR: 2.99; 95% CI: 1.23-7.23).

CONCLUSION

The limited number, heterogeneity, and small sample size of the included studies do not permit definitive conclusions on the association between MRI findings of the cervical spine with future neck pain.

Prognostic Factor Analysis for Management of Chronic Neck Pain: Can We Predict the Severity of Neck Pain with Lateral Cervical Curvature?

Objective

Although little is known about its origins, neck pain may be related to several associated anatomical pathologies. We aimed to characterize the incidence and features of chronic neck pain and analyze the relationship between neck pain severity and its affecting factors.

Methods

Between March 2012 and July 2013, we studied 216 patients with chronic neck pain. Initially, combined tramadol (37.5 mg) plus acetaminophen (325 mg) was administered orally twice daily (b.i.d.) to all patients over a 2-week period. After two weeks, patients were evaluated for neck pain during an outpatient clinic visit. If the numeric rating scale of the patient had not decreased to 5 or lower, a cervical medial branch block (MBB) was recommended after double-dosed previous medication trial. We classified all patients into two groups (mild vs. severe neck pain group), based on medication efficacy. Logistic regression tests were used to evaluate the factors associated with neck pain severity.

Results

A total of 198 patients were included in the analyses, due to follow-up loss in 18 patients. While medication was successful in reducing pain in 68.2% patients with chronic neck pain, the remaining patients required cervical MBB. Lateral cervical curvature, such as a straight or sigmoid type curve, was found to be significantly associated with the severity of neck pain.

Conclusion

We managed chronic neck pain with a simple pharmacological management protocol followed by MBB. We should keep in mind that it may be difficult to manage the patient with straight or sigmoid lateral curvature only with oral medication.
