An Updated Overview of the Magnetic Resonance Imaging of Brain Iron in Movement Disorders.

Brain iron load is one of the most important neuropathological hallmarks in movement disorders. Specifically, the iron provides most of the paramagnetic metal signals in the brain and its accumulation seems to play a key role, although not completely explained, in the degeneration of the basal ganglia, as well as other brain structures. Moreover, iron distribution patterns have been implicated in depicting different movement disorders.

Pulmonary thromboembolism in critical ill COVID-19 patients.

• COVID-19 in critically ill patients causes death not only from pneumonia but also from multiple organ injuries. • In critically ill COVID-19 patients with pneumonia, pulmonary thromboembolism may be considered. • In critically ill COVID-19 patients, contrast-enhanced computed tomography of the chest is mandatory to assess parenchymal patterns and to diagnose pulmonary thromboembolism.
