Surgeons, Physiatrists And Neurologists Speaking "Edx And Nerve Surgery": A Paradigm Shift For Nerve Injured Patients, Deng Pan, Aneri U Patel, J Megan Patterson, Anna Rose Johnson, Travis Gordon, Susan E Mackinnon

2020-Current year OA Pubs

Surgeons' ability to interpret electrodiagnostic (EDX) studies has greatly enhanced patient selection and outcome for nerve surgeries as it has informed our understanding of the classification of nerve injury. EDX measures axons present, lost, or demyelinated. It does not measure an area where axons experience chronic ischemia, making a Sunderland Zero nerve injury a clinical diagnosis that should be suspected when patients have normal EDX, decreased recruitment on electromyography (EMG), and no atrophy. Only observation of recovery in the earliest postoperative period would confirm a Sunderland Zero. In this article, we present an expanded classification of nerve injury, highlighting Sunderland …

Petechiae And A Persistent Violaceous Nodule: A Presentation Of Blastic Plasmacytoid Dendritic Cell Neoplasm To Dermatology., Madison Anzelc, Christina Druskovich, Austin Cusick, Matthew Franklin

Ambulatory and Primary Care Articles

Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare, highly aggressive CD4+ CD56+ hematopoietic malignancy. The cutaneous presentation is variable but often includes violaceous nodules. We present a rare case of BPDCN, which featured dermatological findings consisting of erythematous macules, petechiae, purpura, and a violaceous nodule. A skin biopsy and peripheral blood smear supported a diagnosis of BPDCN. With BPDCN favoring cutaneous involvement, we urge dermatologists to be aware of the possibility of a BPDCN diagnosis in patients who present with purpuric nodules and petechial skin findings, especially when it is not easily explainable by another pathology or medication.

Little is known about the mechanisms that generate epileptic spasms following perinatal brain injury. Recent studies have implicated reduced levels of Insulin-like Growth Factor 1 (IGF-1) in these patients' brains. Other studies have reported low levels of the inhibitory neurotransmitter, GABA. In the TTX brain injury model of epileptic spasms, we undertook experiments to evaluate the impact of IGF-1 deficiencies on neocortical interneurons and their role in spasms. Quantitative immunohistochemical analyses revealed that neocortical interneurons that express glutamic acid decarboxylase, parvalbumin, or synaptotagmin 2 co-express IGF-1. In epileptic rats, expression of these three interneuron markers were reduced in the neocortex. …

School of Medicine Faculty Publications

This study focuses on the effect of Environmentally Persistent Free Radicals (EPFRs) on the P450 enzymes of the CYP1 family. EPFRs are a component of particulate pollutants, that are stable in the environment, but can generate free radicals, leading to oxidative stress and subsequent toxicity of the respiratory, cardiovascular, and immune systems once they enter an organism. The results show differences in the ability of EPFRs to inhibit CYP1-dependent substrate metabolism, with CYP1B1 being inhibited to the greatest extent. There also were differences in the ability of EPFRs to disrupt the POR•CYP1 complex, with CYP1B1 being the only form where …
