Observational Study
Impact of a Pregabalin Step Therapy Policy Among Medicare Advantage Beneficiaries.
Managed healthcare organizations often utilize formulary management strategies such as prior authorization and step therapy to guide appropriate medication use and to control medication expenditures. The objective of this study was to examine clinical and economic outcomes associated with implementation of a pregabalin step therapy (ST) policy among Medicare Advantage Prescription Drug (MAPD) members. ⋯ After controlling for differences in age and comorbidity burden between the groups, implementation of a pregabalin ST restriction was associated with increased disease-related pharmacy costs and decreased total medical costs; however, there was no net difference in total healthcare cost or total pharmacy cost.

The aim of this study was to investigate the effect of individual pain sensitivity on the results of transforaminal epidural steroid injection (TFESI) for the patients with lumbar spinal stenosis (LSS). Seventy-seven patients with LSS were included in this study. Prospectively planned evaluations were performed twice consecutively before and 2 months after TFESI. ⋯ Before injection, VAS for back pain and leg pain was highly associated with the PSQ scores including total PSQ and PSQ subscores after adjustment for age, BMI, and grade of canal stenosis. However, any subscores of PSQ and total PSQ scores were not correlated with either VAS for back pain/leg pain or ODI 2 months after TFESI with adjustment made to age, BMI, gender, and grade of canal stenosis. This study highlights that individual pain sensitivity does not influence the outcomes of TFESI treatment in patients with LSS, even though pain sensitivity has a significant negative correlation with symptom severity of LSS.

Randomized Controlled Trial
The Effects of Exercise Therapy for the Improvement of Jaw Movement and Psychological Intervention to Reduce Parafunctional Activities on Chronic Pain in the Craniocervical Region.
Apparent organic abnormalities are sometimes not identified among patients suffering from chronic pain in the craniocervical region. In some cases, parafunctional activities (PAs) are recognized. PAs are nonfunctional oromandibular activities that include jaw clenching and bruxism, but are considered as factors that contribute to craniomandibular disorders (CMDs). It is now recognized that PAs and CMDs influence musculoskeletal conditions of the upper quarter. Exercise therapy (ET) to improve jaw movement and psychological intervention (PI) to reduce PAs are useful for PAs and CMDs. We hypothesized that ET and PI would be effective for craniocervical pain without organic abnormalities. ⋯ A combination of jaw exercise and psychological intervention to reduce parafunctional activities is more effective than jaw exercise alone for the improvement of craniocervical pain without apparent organic abnormalities.
