Discharge from the emergency department and early hospital revaluation in patients with COVID-19 pneumonia: a prospective study.

Objective: The national health systems are currently facing the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic. We assessed the efficacy of outpatient management for patients with SARS-CoV-2 related pneumonia at risk of progression after discharge from the emergency department.

Methods: This was a single-center prospective study.

Heart rate variability in cluster headache.

Eight patients with cluster headache were studied by evaluating the heart rate variability on the basis of 24-hour ECG monitoring performed during attacks (critic periods) to demonstrate if any imbalance of the autonomic nervous system was present and to determine its temporal correlation, if any, with the attack. The same monitoring allowed us to compare the patients' data during headache-free periods (intercritic periods) with those of normal controls. Our investigation demonstrated a severe sympathovagal imbalance during spontaneous attacks: the parasympathetic drive is at once increased at the onset with a mild reduction of the sympathetic drive, and all these modifications slowly disappear at the end of each attack.

Salmonella enteritidis pericarditis: case report and review of the literature.

A 65-year-old male patient with primary idiopathic dermatomyositis and on regular immunosuppressive therapy was admitted to our Department for fever and dyspnea. A diagnosis of hemorrhagic Salmonella enteritidis pericarditis was made. Treatment necessitated aggressive medical/surgical supervision.

Favorable response to high-dose interferon-alpha in idiopathic hypereosinophilic syndrome with restrictive cardiomyopathy--case report and literature review.

The idiopathic hypereosinophilic syndrome is characterized by a prolonged overproduction of eosinophils of unknown cause in addition to specific organ damage due to eosinophil-derivated protein toxicity. Its prognosis is correlated with heart involvement that results in a restrictive cardiomyopathy. This is frequently biventricular.
