The objective of this study is to assess clinical variables that may be associated with risk for opioid misuse in individuals with chronic pancreatitis. ⋯ Depression, quality of life, pain intensity and alcohol use may be good candidate variables for prospective studies to determine clinical risk factors for opioid misuse among patients with pancreatitis.

We present a case of a patient with acute lymphoblastic leukemia (ALL) undergoing an epidural blood patch (EBP) for post-puncture dural headaches despite the risks of spreading cancer cells to the epidural space. ⋯ Post-dural puncture headache due to intrathecal administration of chemotherapy agents becomes increasingly recognized, and there are an increasing number of requests to anesthesiologists for EBP. A major concern in the patient population with hematological malignancies is the possibility of neuroaxial seeding of malignancies. Therein, flow cytometry was implemented to screen for blast cells in the circulating blood. Careful analysis and minimization of this potential risk is required to ensure the safety of the EBP in this specific patient population.

Clinical Trial
CT-guided percutaneous infrazygomatic radiofrequency neurolysis through foramen rotundum to treat V2 trigeminal neuralgia.
Percutaneous radiofrequency thermocoagulation or neurolysis of Gasserian ganglion through foramen ovale (FO) is the classical approach to treat trigeminal neuralgia (TN). However, it has been technically challenging when individual trigeminal sub-branch nerve block is desired through this approach. We have thus developed a novel computed tomograph-guided technique to block the V2 trigeminal nerve through foramen rotundum (FR). With this technique, we have conducted a study of 27 patients with isolated V2 TN. We hypothesize that this new technique will have comparable clinical outcome with the conventional FO approach. ⋯ We have developed a novel technique to selectively block the V2 trigeminal nerve at FR. This novel FR approach may be a good alternative to the classical FO approach when an isolated V2 branch block is desired.

Despite rapidly increasing intervention, functional disability due to chronic low back pain (cLBP) has increased in recent decades. We often cannot identify mechanisms to explain the major negative impact cLBP has on patients' lives. Such cLBP is often termed non-specific, and may be due to multiple biologic and behavioral etiologies. Researchers use varied inclusion criteria, definitions, baseline assessments, and outcome measures, which impede comparisons and consensus. ⋯ A task force was convened by the NIH Pain Consortium with the goal of developing research standards for chronic low back pain. The results included recommendations for definitions, a minimum dataset, reporting outcomes, and future research. Greater consistency in reporting should facilitate comparisons among studies and the development of phenotypes.
