Power modulation spectrum - a promising approach for the indispensable quality control of electrocardiogram signals from monitoring units for the detection of autonomic dysfunction.

Objective: Electrocardiogram (ECG) is essential for evaluating the autonomic nervous system. Ensuring the quality of real-world ECG datasets is critical, but manual control of large datasets is impractical. Thus, automated quality control is necessary.

Retrospective analysis of COVID-19 patients with Guillain-Barre, Miller-Fisher, and opsoclonus-myoclonus-ataxia syndromes-a case series.

Background: In accordance with the rising number of SARS-CoV‑2 infections, reports of neurological complications have also increased. They include cerebrovascular diseases but also immunological diseases such as Guillain-Barre syndrome (GBS), Miller-Fisher syndrome (MFS), and opsoclonus-myoclonus-ataxia syndrome (OMAS). While GBS and MFS are typical postinfectious complications, OMAS has only recently been described in the context of COVID-19.

[Myalgic encephalomyelitis/chronic fatigue syndrome: an overview of current evidence].

Over the past 5 years both media and scientific interest has surged regarding the disorder myalgic encephalomyelitis and chronic fatigue syndrome (ME/CFS), not least because of the clinically similar manifestation in long COVID or post-COVID. In this review we discuss the process of clinical diagnosis and randomized controlled therapeutic studies on ME/CFS, and the similarities or differences to long COVID and post-COVID. So far, neither clear pathophysiologically causal nor therapeutic evidence-based results on ME/CFS have been identified in the many years of scientific research.

MOG antibody associated disease (MOGAD) presenting with extensive brain stem encephalitis: A case report.

Background: Myelin oligodendrocyte glycoprotein antibody disease (MOGAD) is a relatively new entity of demyelinating diseases, clinically presenting with optic neuritis, transverse myelitis, or encephalic symptoms. Typical radiological features include demyelinating cerebral and spinal lesions, cortical involvement, leptomeningeal enhancement, or tumefactive lesions. Here we present a rare case of a young patient with extensive brain stem lesion on the MRI while exhibiting nystagmus, singultus and somnolence.
