Magnetic resonance (MR) scans are routine clinical procedures for monitoring people with multiple sclerosis (PwMS). Patient discomfort, timely scheduling, and financial burden motivate the need to accelerate MR scan time. We examined the clinical application of a deep learning (DL) model in restoring the image quality of accelerated routine clinical brain MR scans for PwMS.

Article Synopsis
  • Immune checkpoint inhibitors (ICIs) are a promising cancer treatment that can have serious side effects, especially in patients with preexisting autoimmune disorders like multiple sclerosis (MS).
  • A case study reported significant improvement in a man with both metastatic non-small cell lung cancer (NSCLC) and MS after treatment with atezolizumab, but he also experienced a severe MS flare that stopped further treatment.
  • Diagnosing complications in patients with both MS and brain tumors is complicated because symptoms could indicate tumor growth, an MS flare-up, or radiation necrosis, making management difficult.

Intraoperative electrocorticography (ECoG) is a useful technique to guide resections in epilepsy surgery and is mostly performed under general anesthesia. In this systematic literature review, we seek to investigate the effect of anesthetic agents on the quality and reliability of ECoG for localization of the epileptic focus. We conducted a systematic search using PubMed and EMBASE until January 2019, aiming to review the effects of anesthesia on ECoG yield.

Objective: To recount the evolution of Electrical Cortical Stimulation (ECS) in localizing brain functions with an emphasis on epilepsy, and a discussion of related instruments and personnel.

Design/methods: Literature review through historical archives implementing chain-referral sampling.

Results: There were important milestones leading to the incorporation of ECS into practice: 1.

Epigenetic annotation studies of genetic risk variants for multiple sclerosis (MS) implicate dysfunctional lymphocytes in MS susceptibility; however, the role of central nervous system (CNS) cells remains unclear. We investigated the effect of the risk variant, rs7665090, located near NFKB1, on astrocytes. We demonstrated that chromatin is accessible at the risk locus, a prerequisite for its impact on astroglial function.

Cefepime is a fourth generation cephalosporin which is bactericidal for broad spectrum of organisms. This is a case-series of three patients who presented to our hospital with confusion secondary to cefepime use to treat urinary tract infection (UTI) and health care associated pneumonia (HCAP), after excluding other common etiologies of altered mental status (AMS). Of these three patients, one had progressive expressive aphasia and the other two demonstrated asynchronous myoclonic activity of the limbs.

From 377 consecutive MEG studies for patients with intractable epilepsy performed at the Cleveland Clinic between 2008 and 2011, 19 patients were referred for a repeat MEG. Source localization was done using a single equivalent current dipole (ECD) model on identified interictal spike activity. Clinical, neuroimaging, and concurrent EEG and MEG findings were reviewed.
