Background and purpose: The objective of this study was to assess the neurological manifestations in a series of consecutive severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-positive patients, comparing their frequency with a population hospitalized in the same period for flu/respiratory symptoms, finally not related to SARS-CoV-2. Methods: Patients with flu/respiratory symptoms admitted to Fondazione Policlinico Gemelli hospital from 14 March 2020 to 20 April 2020 were retrospectively enrolled. The frequency of neurological manifestations of patients with SARS-CoV-2 infection was compared with a control group. Results: In all, 213 patients were found to be positive for SARS-CoV-2, after reverse transcriptase polymerase chain reaction on nasal or throat swabs, whilst 218 patients were found to be negative and were used as a control group. Regarding central nervous system manifestations, in SARS-CoV-2-positive patients a higher frequency of headache, hyposmia and encephalopathy always related to systemic conditions (fever or hypoxia) was observed. Furthermore, muscular involvement was more frequent in SARS-CoV-2 infection. Conclusions: Patients with COVID-19 commonly have neurological manifestations but only hyposmia and muscle involvement seem more frequent compared with other flu diseases.

An 18-year-old man presented to our hospital with muscular pain, diffuse petechiae, spontaneous thigh ecchymosis, edema and pain of the right knee, bilateral pretibial subcutaneous nodules, and gingival hypertrophy and hemorrhage. His history was positive for a mixed anxiety-depressive disorder and a restrictive diet caused by self-diagnosed food allergies. Skin lesions appeared like hyperkeratotic papules with coiled hairs and perifollicular hemorrhages. A diagnosis of scurvy was made upon demonstration of low serum levels of ascorbic acid. An allergy evaluation found cross-reactivity between pollens and food, related to the presence of panallergens. Moreover, we found that our patient was also affected by celiac disease. In conclusion, scurvy should be considered in the differential diagnosis of patients with petechiae and ecchymosis, especially when food restriction, malabsorption, or psychiatric disorders are present.

Background and aims:The COVID-19 pandemic represents a source of stress and potential burnout for many physicians. This single-site survey aimed at assessing perceived stress and risk to develop burnout syndrome among physicians operating in COVID wards.Methods: This longitudinal survey evaluated stress and burnout in 51 physicians operating in the COVID team of Gemelli Hospital, Italy.Participants were asked to complete the Maslach Burnout Inventory (MBI) and the Perceived Stress Questionnaire on a short run (PSQs) (referring to the past 7 days) at baseline (T0) and then for four weeks (T1-T4). Perceived Stress Questionnaire on a long run (PSQl) (referring to the past 2 years) was completed only at T0. Results:Compared with physicians board-certified in internal medicine, those boardcertified in other disciplines showed higher scores for the Emotional Exhaustion (EE) score of the MBI scale (P < .001). Depersonalisation (DP) score showed a reduction over time (P = .002). Attending physicians scored lower than the resident physicians on the DP scale (P = .048) and higher than resident physicians on the Personal Accomplishment (PA) scale (P = .04). PSQl predicted higher scores on the EE scale (P = .003), DP scale (P = .003) and lower scores on the PA scale (P < .001). PSQs showed a reduction over time (P = .03). Attending physicians had a lower PSQs score compared with the resident physicians (P = .04).

I would like to thank my collaborators, Prof. Emilian Dudas, Cezar Condeescu and Prof. Ioannis Florakis, for the stimulating discussions that expanded my knowledge and opened new perspectives on the topics I have been working on.A special thank is deserved to my collaborator and friend, Ivano Basile, who taught me a lot of new physics I did not know of and opened my eyes to new worlds to be explored, as well as for his kindness and availability even outside physics. His passion and enthusiasm have been stimulating and inspirational in my research activity.During these years I had the opportunity to be involved in interesting conversations, from which my work undoubtedly benefited, with many brilliant colleagues and senior scientists including Prof.
