Electroencephalographic Abnormalities are Common in COVID-19 and are Associated with Outcomes.

Objective: The aim was to determine the prevalence and risk factors for electrographic seizures and other electroencephalographic (EEG) patterns in patients with Coronavirus disease 2019 (COVID-19) undergoing clinically indicated continuous electroencephalogram (cEEG) monitoring and to assess whether EEG findings are associated with outcomes.

Methods: We identified 197 patients with COVID-19 referred for cEEG at 9 participating centers. Medical records and EEG reports were reviewed retrospectively to determine the incidence of and clinical risk factors for seizures and other epileptiform patterns.

MRI may be used as a prognostic indicator in patients with extra-abdominal desmoid tumours.

Objective: To determine the association of MRI features of extra-abdominal desmoid tumours (DTs) with prognosis.

Methods: MRIs for 90 patients with DT were retrospectively reviewed for imaging features associated with biological behaviour. The primary end point was progression (for lesions managed with chemotherapy, radiation therapy and observation) or recurrence (following surgery).

Comparison of the utility of covered metal stents versus uncovered metal stents in the management of malignant biliary strictures in 749 patients.

Background: Self-expandable metal stents (SEMSs) are used to relieve malignant biliary obstruction.

Objective: To compare outcomes between covered self-expandable metal stents (CSEMSs) and uncovered self-expandable metal stents (USEMSs) in malignant biliary obstruction.

Design: Retrospective cohort study.
