Preventing Spinal Cord Injury in Single-Staged Juxtarenal and Thoracoabdominal Endovascular Aortic Aneurysm Repair: An Evaluation of Cerebrospinal Fluid Catheter Drainage.

Objective: This study offers a retrospective assessment of a single-center experience using cerebrospinal fluid catheters to reduce the risk of perioperative spinal cord injury in patients undergoing single-staged complex endovascular juxtarenal or thoracoabdominal aortic aneurysm repair.

Results: A total of 97 patients were included. On average, 70.

Treatment of neuropathic pain with the capsaicin 8% patch: Quantitative sensory testing (QST) in a prospective observational study identifies potential predictors of response to capsaicin 8% patch treatment.

Background and aims Peripheral neuropathic pain (PNeP) is a chronic and disabling condition for which no predictors of response to treatment have yet been identified. Clinical studies show that while many patients with PNeP respond positively to treatment with the capsaicin 8% patch, others do not. This study used quantitative sensory testing (QST) to determine whether any patient characteristics can predict response to treatment with the capsaicin 8% patch.

Central origin of pinprick hyperalgesia adjacent to an UV-B induced inflammatory skin pain model in healthy volunteers.

Background and purpose The UV-B model is an established pain model of different types of hyperalgesia in animal and human pain research. Beside the skin region of the sunburn in human volunteers pinprick hyperalgesia has been described in a large zone of non-inflamed skin adjacent to the sunburn. However, there are opposing results on the existence of pinprick hyperalgesia and most notably a controversial discussion is still on-going whether this mechanical hyperalgesia in the undamaged tissue adjacent to and at some distance from the site of inflammation is of peripheral or central origin.
