[COVID-19: Neurological manifestations and complications during the acute phase of the disease].

The neurological manifestations and complications of the acute phase of COVID-19 are numerous. They mainly concern the central nervous system in the frequent forms of encephalopathy, encephalitis and neurovascular pathologies. Peripheral neurological manifestations mainly include acute polyneuropathies such as Guillain-Barré syndrome and intensive care neuromyopathies.

Marked increase in severe neurological disorders after nitrous oxide abuse: a retrospective study in the Greater Paris area.

Background: Recreational nitrous oxide (NO) use has become more widespread worldwide, leading to an increase in myelopathies and peripheral neuropathies. The aim of this study was to describe clinical and socioeconomical characteristics of severe NO-induced (NI) neurological disorders (NI-NDs), to determine its incidence in the Greater Paris area and to compare it with that of similar inflammatory neurological disorders.

Methods: We performed a retrospective multicentric cohort study of all adult patients with severe NI-NDs in the neurology and general internal medicine departments of the Greater Paris area from 2018 to 2021.

First-ever acute ischemic strokes in HIV-infected persons: A case-control study from stroke units.

Objective: The stroke risk for persons living with human immunodeficiency virus (PLHIVs) doubled compared to uninfected individuals. Stroke-unit (SU)-access, acute reperfusion therapy-use and outcome data on PLHIVs admitted for acute ischemic stroke (AIS) are scarce.

Methods: AIS patients admitted (01 January 2017 to 31 January 2021) to 10 representative Paris-area SUs were screened retrospectively from the National Hospitalization Database.

Incidence, risk factors and treatment of central nervous system immune reconstitution inflammatory syndrome in non-HIV patients with tuberculous meningitis: a multicentre observational study.

Background: Immune reconstitution inflammatory syndrome (IRIS) affecting the central nervous system (CNS) is associated with poor outcomes.

Aims: To report on risk factors for CNS-IRIS following tuberculous meningitis (TBM) in HIV-negative patients.

Methods: In this retrospective multicentre study, all HIV-negative adult patients admitted between 2003 and 2021 with microbiologically proven TBM were included.
