Childhood focal compressive mononeuropathies during the COVID-19 pandemic in Buenos Aires, Argentina

Introduction/Aims

Focal peripheral neuropathies are infrequently seen in pediatric patients. The COVID‐19 pandemic has disrupted normal life for many people, including complete lockdowns and school closing for long periods of time in many countries, which prompted children to stay at home. Our aim is to assess whether there has been an increased incidence of focal compressive peripheral neuropathies in the pediatric population during COVID‐19–associated lockdown.

Methods

Clinical, electrophysiological, and imaging characteristics were reviewed for patients referred to the electrodiagnostic (EDx) laboratory with suspicion of a focal neuropathy. The incidence of focal compressive peripheral neuropathies seen during the period of March to September 2020 was compared with the same time period in 2019.

Results

An increased incidence of focal neuropathies was seen in 2020 (31%) compared with 2019 (6.8%). During 2020, 7 fibular (peroneal) mononeuropathies and 2 ulnar neuropathies were diagnosed. Most patients with focal neuropathies were underweight and acknowledged prolonged screen time periods. Electrophysiological findings consisted of mostly demyelinating lesions with an overall good clinical outcome.

Discussion

In this study we raise awareness about a possible increased incidence of focal compressive peripheral neuropathies in children during COVID‐19–associated lockdown, which may be prevented with changing positions during sedentary activities.
