In the meantime, different names and provisional case definitions are being used around the world. The initial case definitions released by the World Health Organization (WHO), the Royal College of Paediatrics and Child Health (RCPCH) and Centers for Disease Control and Prevention (CDC) all include involvement of more than one organ system, along with fever and elevated inflammatory markers. Criteria that vary among these three definitions include the ways in which involvement of different organs is defined, the duration of fever, and how exposure to COVID-19 is assessed. The preliminary WHO case definition is for "multisystem inflammatory syndrome (MIS) in children and adolescents temporally related to COVID-19" (box). The WHO has established a platform for standardized, anonymized clinical data, along with a dedicated case report form, and underlines the "urgent need for collection of standardized data describing clinical presentations, severity, outcomes, and epidemiology." Diagnostic guidance by the RCPCH proposes a broader case definition (for PIMS-TS), which was also endorsed by an expert panel convened by the American College of Cardiology. Key clinical criteria set out in the RCPHC case definition are: persistent fever, inflammation (indicated by neutrophilia, high CRP levels and low lymphocyte count), and evidence of organ dysfunction (shock; cardiac, respiratory, renal, gastrointestinal, or neurological disorder), coupled with additional clinical features, including laboratory, imaging and ECG findings. Coronary artery abnormalities, such as dilatation, may be apparent at echocardiography and ECG (or contrast CT of the chest). Biomarkers supporting the diagnosis include abnormal fibrinogen levels, high D-dimers (possible coagulopathy), high troponin, low albumin, and high ferritin.
Lucid dreaming
Though not approved by the FDA, there is interest in the recreational use of galantamine for its purported ability to induce lucid dreaming. One study has provided some limited evidence for this practice, although it is notable that its authors have financial ties to the Lucidity Institute. See also
