COVID-19 associated phrenic nerve mononeuritis: a case series.

This study characterised the hemidiaphragm elevation on 3-month interval chest X-rays (CXRs) of patients post COVID-19 pneumonia. 467 CXRs were screened; 19 (4.1%) had an elevated hemidiaphragm.

Inhibition of complement in Guillain-Barré syndrome: the ICA-GBS study.

The outcome of Guillain-Barré syndrome (GBS) remains unchanged since plasma exchange and intravenous immunoglobulin (IVIg) were introduced over 20 years ago. Pathogenesis studies on GBS have identified the terminal component of complement cascade as a key disease mediator and therapeutic target. We report the first use of terminal complement pathway inhibition with eculizumab in humans with GBS.

Concentric and single fiber needle electrodes yield comparable jitter results in myasthenia gravis.

The single fiber needle electrode (SFNE), which is designed to isolate single muscle fiber action potentials, has played an important role in the diagnosis of myasthenia gravis (MG). However, the concentric needle electrode (CNE) has been recently adopted by some workers to study neuromuscular instability in MG, and reference data have also been obtained in healthy subjects. In this study we wanted to establish whether data acquired using the SFNE is comparable to that obtained using the CNE when studying patients with MG.

Electro-clinical phenotypes of chromosome disorders associated with epilepsy in the absence of dysmorphism.

Chromosome imbalances are associated with epilepsy but electro-clinical phenotypes are lacking for all but the best-known syndromes. Scanty information is contained in older case reports published in genetics journals that describe children with severe patterns of malformation and dysmorphism. From a larger series of children with chromosome abnormalities and epilepsy, we identified 10 patients with associated dysmorphism without malformation.
