Intraosseous lipomas are rare benign tumors of the bone, especially for the mandible. The etiology remains unclear, although several hypotheses have been proposed, such as trauma, blood vessel infarction, aging and inflammation. Clinically, the symptoms mainly depend on the location and size of the tumors. Radiographically, the lesions are usually radiolucent occasionally accompanied by radiopacity. The diagnosis is challenging, and histopathologic examination is necessary for definite diagnosis....

I have read with great interest the recent article by Franco et al, recently reported in this journal[1]. The authors have uniquely examined the association between alexithymia personality with increased burnout and less professional satisfaction[1]. They also linked empathic concern with increased stress, without leading to burnout, but resulting in higher professional fulfilment[1].

The novel human Coronavirus (SARS-CoV-2), which outbroke in Wuhan (China) in late 2019, is now responsible for the pandemic diffusion of COVID-19 [1–3]. Researchers are working on the validation of effective protocols, including antiviral therapies and vaccines [4]. Case-fatality rate seems correlated with virally-driven hyperinflammation [4,5]. In this sense, recent data suggest a crucial role for cytokines release syndrome (CRS) and human interleukin-6 (IL-6) levels as fatality predictors [4,5].
