Sciatic neuropathy with preserved sensory nerve action potentials, a case series

Background: Sciatic neuropathy is differentiated from lumbosacral radiculopathy based on the finding of abnormal sensory nerve action potentials (SNAPs). Cases of sciatic neuropathy with intact SNAPS have not been well described. Methods: A retrospective analysis of 12 patients with sciatic neuropathy in a single institution. Results: We describe 12 patients in whom a sciatic neuropathy was diagnosed based on a combination of history, physical exam, radiological and electrodiagnostic (EDX) findings. Lower extremity SNAPs were found to be within normal range in all patients, although SNAP amplitude asymmetry between both sides was observed in 3. Included patients were young (mean age of 40.3 years) and mostly female (9 patients). Conclusions: Sciatic neuropathy may occur with a relative sparing of sensory fibers. Recognition of this group of patients should help to avoid making a misdiagnosis of lumbosacral radiculopathy

Methotrexate Use in Generalized Autoimmune Myasthenia Gravis: A Case series

Methotrexate (MTX) is an inexpensive and well-tolerated immunosuppressive medication that is used anecdotally in autoimmune myasthenia gravis (MG). However, the efficacy in MG is unclear at this time. This retrospective analysis describes six patients with acetylcholine receptor antibody positive MG who were treated with MTX and corticosteroids. The efficacy of MTX was measured by steroid-sparing effect and the Myasthenia Gravis Foundation of America (MGFA) classification. MTX initiation was associated with a reduction in prednisone dosage in all patients. Minimal manifestation status was reached at an average duration of 10 months in 5 patients.  No patients were hospitalized for myasthenia gravis exacerbations. There were no major side effects experienced with MTX use.  This retrospective analysis suggests that MTX is safe and probably efficacious as a corticosteroid-sparing agent in the management of MG

Neuromuscular Complications in COVID-19: A Review of the Literature

Coronavirus disease of 2019 (COVID-19) belongs to the betacoronavirus family which is known to cross species barriers and lead to high pathogenicity. There is rapidly growing evidence that COVID-19 infection can be associated with neuromuscular complications. A comprehensive literature review was conducted evaluating articles published related to neuromuscular complications in COVID-19.  In this review we focus our discussion on two ways that COVID-19 critically impacts neuromuscular medicine: (1) serious complications and outcomes associated with the viral infection and; (2) management considerations for neuromuscular patients on immunotherapies during the COVID-19 pandemic. &nbsp

Identification of potential biomarkers to differentially diagnose solid pseudopapillary tumors and pancreatic malignancies via a gene regulatory network

Additional file 1: In-degree distribution for GRN. X-axis represents the in-degree for a certain node. A node of in-degree x means that this node is regulated by a total number of x other nodes. Y-axis represents the total number of network nodes which has an in-degree of x. The red curve was the fitting to the power law distribution. (A): The in-degree distribution for sub-GRN in which only miRNAs are included as regulators and the in-degree for each node (miRNAs and protein coding genes) was calculated in this sub-GRN. The in-degree ranges from 0 to 27. (B): In-degree distribution for sub-GRN in which only TFs are included as regulators

Light-driven C-H bond activation mediated by 2D transition metal dichalcogenides

C-H bond activation enables the facile synthesis of new chemicals. While C-H activation in short-chain alkanes has been widely investigated, it remains largely unexplored for long-chain organic molecules. Here, we report light-driven C-H activation in complex organic materials mediated by 2D transition metal dichalcogenides (TMDCs) and the resultant solid-state synthesis of luminescent carbon dots in a spatially-resolved fashion. We unravel the efficient H adsorption and a lowered energy barrier of C-C coupling mediated by 2D TMDCs to promote C-H activation. Our results shed light on 2D materials for C-H activation in organic compounds for applications in organic chemistry, environmental remediation, and photonic materials
