Three Patients With Chorea and Positive Voltage-Gated Potassium Channel Antibody: Is This the Link Between Hyperkinetic von Economo Disease and COVID-19?

Chorea, hemichorea, and other movement disorders have been reported after different pandemics since Constantin von Economo's time. In the current COVID-19 pandemic, numerous delayed neurological manifestations have been reported in the postinfectious or postvaccination periods. However, very few of these are movement disorders in nature; there are even fewer voltage-gated potassium channel (VGKC) antibody-related movement disorder cases in the literature. We encountered three patients with some COVID-19-related issues featuring both chorea and VGKC antibody. Modern medical science and technology may be able to further our understanding of the molecular basis of von Economo disease and reveal a possible link to COVID-19 along with the immunomodulation aspect of its treatment.

A Novel Virtual Wet Lab-Using a Smartphone Camera Adapter and a Video Conference Platform to Provide Real-Time Surgical Instruction.

PURPOSE: Proctored surgical instruction has traditionally been taught through in-person interactions in either the operating room or an improvised wet lab. Because of the COVID-19 pandemic, live in-person instruction was not feasible owing to social distancing protocols, so a virtual wet lab (VWL) was proposed and implemented. The purpose of this article is to describe our experience with a VWL as a Descemet membrane endothelial keratoplasty (DMEK) skills-transfer course. This is the first time that a VWL environment has been described for the instruction of ophthalmic surgery. METHODS: Thirteen participant surgeons took part in VWLs designed for DMEK skills transfer in September and October 2020. A smartphone camera adapter and a video conference software platform were the unique media for the VWL. After a didactic session, participants were divided into breakout rooms where their surgical scope view was broadcast live, allowing instructors to virtually proctor their participants in real time. Participants were surveyed to assess their satisfaction with the course. RESULTS: All (100%) participants successfully injected and unfolded their DMEK grafts. Ten of the 13 participants completed the survey. Respondents rated the experience highly favorably. CONCLUSIONS: With the use of readily available technology, VWLs can be successfully implemented in lieu of in-person skills-transfer courses. Further development catering to the needs of the participant might allow VWLs to serve as a viable option of surgical education, currently limited by geographical and social distancing boundaries.

A survey and panel discussion of the effects of the COVID-19 pandemic on paediatric urological productivity, guideline adherence and provider stress.

INTRODUCTION: The COVID-19 pandemic has led to an unprecedented need to re-organise and re-align priorities for all surgical specialties. Despite the current declining numbers globally, the direct effects of the pandemic on institutional practices and on personal stress and coping mechanisms remains unknown. The aims of this study were to assess the effect of the pandemic on daily scheduling and work balances, its effects on stress, and to determine compliance with guidelines and to assess whether quarantining has led to other areas of increased productivity. METHODS: A trans-Atlantic convenience sample of paediatric urologists was created in which panellists (Zoom) discussed the direct effects of the COVID-19 pandemic on individual units, as well as creating a questionnaire using a mini-Delphi method to provide current semi-quantitative data regarding practice, and adherence levels to recently published risk stratification guidelines. They also filled out a Perceived Stress Scale (PSS) questionnaire to assess contemporary pandemic stress levels. RESULTS: There was an 86% response rate from paediatric urologists. The majority of respondents reported near complete disruption to planned operations (70%), and trainee education (70%). They were also worried about the effects of altered home-lives on productivity (≤90%), as well as a lack of personal protective equipment (57%). The baseline stress rate was measured at a very high level (PSS) during the pandemic. Adherence to recent operative guidelines for urgent cases was 100%. CONCLUSION: This study represents a panel discussion of a number of practical implications for paediatric urologists, and is one of the few papers to assess more pragmatic effects and combines opinions from both sides of the Atlantic. The impact of the pandemic has been very significant for paediatric urologists and includes a decrease in the number of patients seen and operated on, decreased salary, increased self-reported stress levels, substantially increased telemedicine usage, increased free time for various activities, and good compliance with guidelines and hospital management decisions.
