Management of a Cancer Patient with an Intrathecal Drug Delivery System and an Acute Brain Abscess.

Surgical-site infection, spinal cord abscess, and catheter tip granuloma are known but rare complications of intrathecal drug delivery systems (IDDS). To date, there are no published cases of brain abscess in a patient with an IDDS. In this study, we report a case of a cancer patient with an IDDS for management of cancer pain who developed a brain abscess with profound mental status changes and clinical management challenges.

A Prospective Randomized Trial of Prognostic Genicular Nerve Blocks to Determine the Predictive Value for the Outcome of Cooled Radiofrequency Ablation for Chronic Knee Pain Due to Osteoarthritis.

Background And Objectives: Genicular nerve radiofrequency ablation is an effective treatment for patients with chronic pain due to knee osteoarthritis; however, little is known about factors that predict procedure success. The current study evaluated the utility of genicular nerve blocks to predict the outcome of genicular nerve cooled radiofrequency ablation (cRFA) in patients with osteoarthritis.

Methods: This randomized comparative trial included patients with chronic knee pain due to osteoarthritis.

Cooled Radiofrequency Ablation of the Genicular Nerves for Chronic Pain due to Knee Osteoarthritis: Six-Month Outcomes.

Objective: Determine outcomes of cooled radiofrequency ablation (C-RFA) of the genicular nerves for treatment of chronic knee pain due to osteoarthritis (OA).

Design: Cross-sectional survey.

Setting: Academic pain medicine center.
