ABSTRACT
BACKGROUND AND PURPOSE: The Patient Reported Outcomes Measurement Information System is a newly developed outcomes measure promulgated by the National Institutes of Health. This study compares changes in pain and physical function-related measures of this system with changes on the Numeric Rating Pain Scale, Roland Morris Disability Index, and the European Quality of Life scale 5D questionnaire in patients undergoing transformational epidural steroid injections for radicular pain. MATERIALS AND METHODS: One hundred ninety-nine patients undergoing transforaminal epidural steroid injections for radicular pain were enrolled in the study. Before the procedure, they rated the intensity of their pain by using the 0-10 Numeric Rating Pain Scale, Roland Morris Disability Index, and European Quality of Life scale 5D questionnaire. Patients completed the Patient Reported Outcomes Measurement Information System Physical Function, Pain Behavior, and Pain Interference short forms before transforaminal epidural steroid injections and at 3 and 6 months. Seventy and 43 subjects replied at 3- and 6-month follow-up. Spearman rank correlations were used to assess the correlation between the instruments. The minimally important differences were calculated for each measurement tool as an indicator of meaningful change. RESULTS: All instruments were responsive in detecting changes at 3- and 6-month follow-up (P < .0001). There was significant correlation between changes in Patient Reported Outcomes Measurement Information System scores and legacy questionnaires from baseline to 3 months (P < .05). There were, however, no significant correlations in changes from 3 to 6 months with any of the instruments. CONCLUSIONS: The studied Patient Reported Outcomes Measurement Information System domains offered responsive and correlative psychometric properties compared with legacy instruments in a population of patients undergoing transforaminal epidural steroid injections for radicular pain.

BACKGROUND AND PURPOSE: The recently developed National Institutes of Health PROMIS initiative provides reliable and valid measures across many health domains. We correlated changes in pain-related PROMIS measures and changes in both an NRS and the RMDI in patients undergoing spine augmentation. MATERIALS AND METHODS: Fifty patients, composed of 26 women (40-91 years of age; mean, 72.6 years) and 24 men (42-78 years of age, mean, 67.5 years) were enrolled in the study. They were asked at initial presentation and at 30 days to rate the intensity of their pain in the past 24 hours by using a 0-10 pain NRS as well at the 23-item RMDI. Study subjects also completed 3 different PROMIS short forms, including physical function, pain behavior, and pain interference. The Spearman correlation was used to assess the correlation between the scales. The RCI × 1.96 was calculated for each measurement tool as an indicator of change. RESULTS: All instruments were responsive to detection of change during 1 month (all, P < .0001). Correlations between changes in physical function, pain interference, and pain behavior PROMIS scores and changes in RMDI scores were 0.37, 0.44, and 0.42, respectively. Direction of changes (declines versus improvements) in RMDI and other scales were the same in approximately 60% of patients. CONCLUSIONS: All measures evaluated had adequate and comparable psychometric properties. The choice of which measure to use depends on the clinical intent of the intervention.

BACKGROUND: Androgenic alopecia is known to be androgen-dependent. Insulin is found in hair follicles and may play a role in the regulation of androgen metabolism and the hair-growth cycle. OBJECTIVES: To compare the insulin resistance between people with androgenic alopecia and a control group. METHODS: A case-control study was conducted with 97 cases in the patient and 87 in the control group. Serum fasting insulin level, fasting blood glucose, serum total cholesterol, triglyceride and high-density lipoprotein (HDL) were all measured in both groups. RESULTS: There was no difference in serum fasting insulin level, fasting blood glucose, serum total cholesterol, triglyceride, HDL and insulin resistance between the two groups (P > 0.05). CONCLUSION: Despite previous reports suggesting a link, our study found no significant relationship between insulin resistance and androgenic alopecia. Further studies are warranted.
