Acute myocarditis following Comirnaty vaccination in a healthy man with previous SARS-CoV-2 infection.

Myopericarditis following mRNA Covid-19 vaccination has recently been reported to health authorities in a lot of countries. They can occur in very rare cases after either the Moderna (mRNA-1273 - Spikevax) or Pfizer-BioNTech (BNT162b2 - Comirnaty) vaccination. Cases predominately occur in younger adult men within 14 days following the second dose.

[Under-reporting of adverse drug reactions, a problem that also involves medicines subject to additional monitoring. Preliminary data from a single-center experience on novel oral anticoagulants].

Background: Spontaneous reporting system is the most widely used method by pharmacovigilance centers. Its "voluntary nature" represents the main cause of adverse drug reaction (ADR) under-reporting phenomena. The aim of this study was to point out the issue of ADR under-reporting from doctors, particularly serious ADRs and adverse reactions caused by medicinal products subject to additional monitoring, such as novel oral anticoagulants (NOACs).

Pulmonary tumor thrombotic microangiopathy: the challenge of the antemortem diagnosis.

Pulmonary tumor thrombotic microangiopathy (PTTM) is known as a rare and severe cancer-related pulmonary complication. Nowadays, fewer than 80 cases have been reported in the literature and very few cases have been diagnosed antemortem. We describe an autopsy case of PTTM associated with cancer of unknown origin.

[Dronedarone: a real innovation or a mere second-best choice? How to find the way among guidelines, regulatory agencies and daily clinical practice].

Dronedarone is the antiarrhythmic drug with the most complete and wide literature preceding its marketing. Most of these studies showed a good efficacy along with an excellent risk profile, especially in low- and medium-risk patients. Recently, updates of European, American and even Italian guidelines gave dronedarone its own spot into the antiarrhythmic armamentarium, recommending its use both for rhythm control and rate control in non-permanent atrial fibrillation.
