Negative pressure pulmonary edema postextubation following medial nerve repair with sural graft surgery in a young patient: A case report.

Medicine (Baltimore) 2018 Dec;97(52):e13743

The Ohio State University Wexner Medical Center, Department of Anesthesiology.

Rationale: Negative pressure pulmonary edema (NPPE) is a serious well-described pulmonary complication. It occurs after an intense inspiratory effort against an obstructed or closed upper airway and generates a large negative airway pressure, leading to severe pulmonary edema (transvascular fluid filtration and interstitial/alveolar edema) and hypoxemia. We present a case of NPPE following general anesthesia in a patient who underwent median nerve neurorrhaphy with graft from lower left limb (sural nerve) due to sharp injury. Read More

The leptin receptor mutation of the obese Zucker rat causes sciatic nerve demyelination with a centripetal pattern defect.

Ultrastruct Pathol 2018 Sep-Oct;42(5):377-408. Epub 2018 Oct 19.

b Unité de Recherche en Physiologie Moléculaire (URPhyM), Laboratoire de Neurodégénérescence et Régénération, Département de Médecine , Université de Namur , Namur , Belgium.

Young male Zucker rats with a leptin receptor mutation are obese, have a non-insulin-dependent diabetes mellitus (NIDDM), and other endocrinopathies. Tibial branches of the sciatic nerve reveal a progressive demyelination that progresses out of the Schwann cells (SCs) where electron-contrast deposits are accumulated while the minor lines or intermembranous SC contacts display exaggerated spacings. Cajal bands contain diversely contrasted vesicles adjacent to the abaxonal myelin layer with blemishes; they appear dispatched centripetally out of many narrow electron densities, regularly spaced around the myelin annulus.

MRI-based assessment of function and dysfunction in myelinated axons.

Proc Natl Acad Sci U S A 2018 10 8;115(43):E10225-E10234. Epub 2018 Oct 8.

Biomedical MR Laboratory, Mallinckrodt Institute of Radiology, Washington University School of Medicine, St. Louis, MO 63110.

Repetitive electrical activity produces microstructural alteration in myelinated axons, which may afford the opportunity to noninvasively monitor function of myelinated fibers in peripheral nervous system (PNS)/CNS pathways. Microstructural changes were assessed via two different magnetic-resonance-based approaches: diffusion fMRI and dynamic T spectroscopy in the ex vivo perfused bullfrog sciatic nerves. Using this robust, classical model as a platform for testing, we demonstrate that noninvasive diffusion fMRI, based on standard diffusion tensor imaging (DTI), can clearly localize the sites of axonal conduction blockage as might be encountered in neurotrauma or other lesion types.

Nat Commun 2018 09 14;9(1):3751. Epub 2018 Sep 14.

Department of Anesthesiology, Perioperative Care and Pain Medicine, New York University School of Medicine, New York, 10016, NY, USA.

Chronic pain is known to induce an amplified aversive reaction to peripheral nociceptive inputs. This enhanced affective response constitutes a key pathologic feature of chronic pain syndromes such as fibromyalgia. However, the neural mechanisms that underlie this important aspect of pain processing remain poorly understood, hindering the development of treatments. Read More
