Reversible spontaneous EMG activity during myasthenic crisis: Two case reports.

eNeurologicalSci 2019 Mar 20;14:16-18. Epub 2018 Nov 20.

Department of Clinical Neurophysiology, National Hospital for Neurology and Neurosurgery, Queen Square, London, UK.

Background: Myasthenia Gravis (MG) is an antibody-mediated autoimmune neuromuscular disorder, clinically presenting with fatigable variable muscle weakness. Typical electrodiagnostic findings are a decremental response to repetitive nerve stimulation with post-exercise facilitation, and motor unit instability expressed as increased jitter on single fibre-EMG. Presence of spontaneous activity on standard EMG is traditionally considered inconsistent with a diagnosis of MG and would direct the differential diagnosis towards a primary denervating or usually inflammatory myopathic process.

Around the clock: gradient shape and noise impact the evolution of oscillatory segmentation dynamics.

Evodevo 2018 10;9:24. Epub 2018 Dec 10.

2Theoretical Biology, Utrecht University, Padualaan 8, 3584CH Utrecht, Netherlands.

Background: Segmentation, the subdivision of the major body axis into repeated elements, is considered one of the major evolutionary innovations in bilaterian animals. In all three segmented animal clades, the predominant segmentation mechanism is sequential segmentation, where segments are generated one by one in anterior-posterior order from a posterior undifferentiated zone. In vertebrates and arthropods, sequential segmentation is thought to arise from a clock-and-wavefront-type mechanism, where oscillations in the posterior growth zone are transformed into a segmental prepattern in the anterior by a receding wavefront.

Thyroid Disorders Change the Pattern of Response of Angiotensinase Activities in the Hypothalamus-Pituitary-Adrenal Axis of Male Rats.

Front Endocrinol (Lausanne) 2018 30;9:731. Epub 2018 Nov 30.

Department of Health Sciences, University of Jaén, Jaén, Spain.

Thyroid disorders affect the hypothalamic-pituitary-adrenal axis with important consequences on the cardiovascular function in which the renin-angiotensin system plays a major role. Hypo and hyperthyroidism influence the classic main components of the renin-angiotensin system. However, the behavior of other elements of the renin-angiotensin system such as Ang III, Ang 2-10, Ang IV, or AT, regulated by angiotensinase enzymes such as alanyl- (AlaAP), cystinyl- (CysAP), glutamyl- (GluAP), or aspartyl-aminopeptidase (AspAP), has not yet been described.

The University of Texas Medical Branch, Department of Orthopaedic Surgery and Rehabilitation, 301 University Blvd., Rt. 0165, Galveston, TX 77555-0165, United States of America.

Background: Double hamstring autograft for anterior cruciate ligament (ACL) reconstruction is a well-established graft option; however, a major concern with this method arises when the prepared graft is too small. Resorting to allograft can be a solution to this problem, but some surgeons prefer to use autograft in particular situations and some patients may refuse allograft. We investigate the merits of using autogenous quadriceps tendons to augment the insufficient hamstrings and compare the autograft composite graft to a standard hamstrings graft of equal size.

A patient with intractable epilepsy, previous right frontal resection, and active vagus nerve stimulation (VNS) developed new onset quasi-continuous twitching around the left eye. Electroencephalography showed no correlate to the orbicularis oculi twitches apart from myographic potentials at the left supraorbital and anterior frontal electrodes. Magnetoencephalography was performed using spatiotemporal signal space separation to suppress magnetic artifacts associated with the VNS apparatus. Read More

Subconjunctival draining minimally-invasive glaucoma devices for medically uncontrolled glaucoma.

Cochrane Database Syst Rev 2018 Dec 16;12:CD012742. Epub 2018 Dec 16.

Ophthalmology, Nottingham University Hospital, Derby Road, Nottingham, UK, NG7 2UH.

Background: Glaucoma is a leading cause of irreversible blindness. Subconjunctival draining minimally-invasive glaucoma devices such as the Xen gelatin implant and InnFocus stent have been introduced as a treatment to prevent glaucoma progressing.These implants provide a channel to allow aqueous humour from the anterior chamber of the eye to drain into the subconjunctival space on the surface of the eye thus reducing intraocular pressure (IOP) and mimicking the mechanism of the most commonly undertaken glaucoma surgery, trabeculectomy.

Functional connectivity analysis and prediction of cognitive change after carotid artery stenting.

Authors:

J Neurosurg 2018 Dec 14:1-7. Epub 2018 Dec 14.

OBJECTIVEThe neurocognitive course of patients who have undergone cerebral revascularization has been the subject of many studies, and the reported effects of carotid artery stenting (CAS) on cognitive function have varied from study to study. The authors hypothesized that cognitive amelioration after CAS is associated with alteration of the default mode network (DMN) connectivity, and they investigated the correlation between functional connectivity (FC) of the DMN and post-CAS changes in cognitive function in order to find a clinical marker that can be used to predict the effect of cerebral revascularization on patients' cognitive function in this preliminary exploratory study.METHODSThe authors examined post-CAS changes in cognitive function in relation to FC in patients treated for unilateral carotid artery stenosis.
