Introduction: Recreational use of nitrous oxide (NO) is increasing in Western countries, including France. During the COVID-19 pandemic, some authors warned that recreational NO use could increase further as the supply of illicit drugs was impacted by various containment measures.
Methods: We retrospectively analyzed NO exposures reported to the Paris Poison Control Center (France) from 2010/01/01 to 2021/04/15. The Poison Severity Score was used to grade severity.
Results: During the study period, 93 cases of NO recreational exposures were reported (male/female ratio: 1.1; median age: 20.9 years range: [14.8-49.0]). The first case was reported in 2012, 84/93 (90%) and 65/93 (70%) were reported since 2019 and March 17 2020 (first lockdown in France) respectively. Most of the patients were symptomatic (88/93; 95%) and developed neurological symptoms (78/93; 84%). Among the fourteen patients who developed moderate to severe symptoms, eleven were reported after March 2020.
Conclusion: Despite a marked increase in recreational NO exposures during the COVID-19 pandemic, the exact impact of COVID-19 on this increase remains to be determined as it was observed from 2019.

New-onset refractory status epilepticus after SARS-CoV-2 infection: a review of literature.
Croat Med J
December 2024
Athanasios, Nafpliou 1 C, Gerakas 15344, Athens, Greece,
Although severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) primarily affects the respiratory system, neurological symptoms were reported both during acute and post-acute COVID-19. Notably, patients with no history of epilepsy or other neurological conditions developed new-onset refractory status epilepticus (NORSE) weeks, months, or even up to a year following the viral infection. While NORSE is uncommon, it carries a high mortality rate and can result in permanent epilepsy.

Subacute thyroiditis - Is it really linked to viral infection? Retrospective hospital patient registry study.
J Clin Endocrinol Metab
January 2025
Institute of Virology, Faculty of Medicine and University Hospital Cologne, University of Cologne, Cologne, Germany.
Objective: Subacute thyroiditis (SAT) is a painful inflammatory disorder of the thyroid gland, which - after a phase of thyrotoxicosis - leads to transient, or less frequently permanent hypothyroidism. Apart from a strong association with specific HLA alleles, the causes are uncertain. Viral disease has been hypothesised as a trigger, with Enteroviruses, namely Echoviruses and Coxsackieviruses, showing a seasonal distribution that coincides with the incidence of SAT.
