Article Synopsis
- Clinical evaluation of axial spine pain is challenging, and the study aimed to see if three specific clinical history features can indicate C1-2 joint edema on MRI.
- The three features, known as the ASL criteria, include being over 65 years old, experiencing superior cervical/suboccipital pain, and worsening pain with lateral cervical spine rotation.
- The ASL criteria showed a high sensitivity (82%) and reasonable specificity (79%) for diagnosing C1-2 joint edema, suggesting they could be useful in clinical practice.
Background: Morning serum cortisol level (mSCL) is a practical screening tool for hypothalamic-pituitary-adrenal (HPA) axis suppression and has been used to assess for duration of cortisol deficiency after epidural and peripheral glucocorticoid injections. More evidence is needed to establish the utility of mSCL in patients undergoing repeat injections with increasing cumulative glucocorticoid equivalent dose (CGED) that could place them at higher risk of HPA axis suppression.
Objectives: To estimate the prevalence of spine injection candidates with significant HPA axis suppression (sigAS), to understand the correlation between 12 months of CGED and the presence of sigAS based on the timing of mSCL collection after the most recent glucocorticoid injection (within 6 weeks or between 6 weeks and 12 months), and to investigate demographic and clinical factors relating to sigAS.
