Observational StudyValidation of the English Language Pain Sensitivity Questionnaire.
The Pain Sensitivity Questionnaire (PSQ) is predictive of pain-related responses to experimental stimuli in German-speaking individuals. Here, we explored the validation of the English translation of the PSQ (PSQ-E). ⋯ The study demonstrated that a significant correlation exists between the PSQ-E and clinically relevant pain ratings. This study validates the PSQ-E both in terms of measuring pain sensitivity and as possible means of recognizing patients with high pain sensitivity. Defining this subset of patients may have clinical utility in the future.

Case ReportsAberrant Intrathecal Pump Refill: Ultrasound-guided Aspiration of a Substantial Quantity of Subcutaneous Hydromorphone.
Intrathecal drug delivery systems are an effective and increasingly common pain treatment modality for certain patient populations. Pumps are surgically inserted in a subcutaneous abdominal pocket and refilled with highly concentrated medication at regular intervals. ⋯ We describe the injection of hydromorphone into the pump's surrounding subcutaneous pocket, subsequent opioid overdose, and the novel application of ultrasound to visualize and aspirate the subcutaneous drug. Ultrasonography can be used as an effective modality for rapid diagnosis and treatment of an accidental pocket fill.
