Observational Study
The extent of pain is associated with signs of central sensitization in patients with hip osteoarthritis.
Central sensitization may be present in some patients with hip osteoarthritis (OA), often reflected as widespread pain. We examine the association between pain extent with signs of central sensitization and other clinical and psychological features in patients with hip OA. ⋯ Greater pain extent was associated with several measures of signs and symptoms of central sensitization in patients with hip OA. These results support the utility of the pain drawing for identifying signs of central sensitization in patients with hip OA.

Migraine is a heterogeneous condition with multiple clinical manifestations. Machine learning algorithms permit the identification of population groups, providing analytical advantages over other modeling techniques. ⋯ A subgroup of women with migraine who had common migraine intensity was identified with machine learning algorithms.

We sought to refine a screening measure for discriminating a sensitized or normal sensation pain phenotype among African American adults with sickle cell disease (SCD). ⋯ The PR-Lasso offers a way to discriminate a SCD pain phenotype.

Rib fractures occur frequently following blunt chest trauma and induce morbidity and mortality. Analgesia is a cornerstone for their management, and regional analgesia is one of the tools available to reach this objective. Epidural and paravertebral blocks are the classical techniques used, but the serratus plane block (SPB) has recently been described as an effective technique for thoracic analgesia. ⋯ The SPB technique (with or without catheter insertion) in 10 patients who had blunt chest trauma with rib fractures is effective for cough pain control, with a significant decrease in morphine consumption.
