A rare case of acute motor axonal neuropathy and myelitis related to SARS-CoV-2 infection.

We describe a rare case of post-infective Acute Motor Axonal Neuropathy (AMAN) variant of Guillain-Barrè Syndrome (GBS) associated with myelitis and anti-GD1b positivity after SARS-CoV-2 infection. The patient referred to the hospital reporting a history of ten days lasting moderate fever, myalgia and anosmia, with the onset of progressive quadriparesis and ascending paraesthesias in the four limbs since five days from defervescence. A chest computed tomography demonstrated interstitial pneumonia with "ground glass opacities", suggesting Coronavirus disease (COVID-19).

Single-pulse transcranial magnetic stimulation in amyotrophic lateral sclerosis.

Introduction: Transcranial magnetic stimulation (TMS) is one of the best methods to identify changes in the corticospinal tract. We used single-pulse TMS at the beginning of the disease and in the follow-up in a group of patients with amyotrophic lateral sclerosis (ALS).

Methods: We evaluated the corticospinal tract in the bulbar, upper, and lower regions in 55 patients with ALS, and we monitored them for a period of 24 months.

[Rhabdomyolysis and arterial hypertension caused by apparent excess of mineralocorticoids: a case report].

We report the case of a 61-year-old man who was referred to our Institution because of severe hypokalemia, rhabdomyolysis and high blood pressure. Severe hypokalemia may lead to rhabdomyolysis. The plasma aldosterone concentrations were low and the plasma renin activity was suppressed.
