Inflammatory popliteal aneurysm associated with SARS-CoV-2 infection

Background: SARS-CoV-2 infection involves the phase of viral replication and inflammatory response predicting the severity of COVID-19. Vascular involvement in SARS-CoV-2 infection has been well established. Thrombotic complications are common, while only few cases of dilatative diseases have been reported. Case report: We herein report the case of a 65-year-old male patient with an inflammatory 25-mm saccular popliteal artery aneurysm detected six months after symptomatic COVID-19 (pneumonia, and pulmonary embolism). The popliteal aneurysm was surgically managed with aneurysmectomy, and reversed bifurcated vein graft. Histological examination detected the infiltration of monocytes and lymphoid cells into the arterial wall. Conclusions: Popliteal aneurysm could be related to inflammatory response related to SARS-CoV-2 infection. The aneurysmal disease should be considered mycotic and surgically managed without prosthetic grafts

A multi analytical characterization of a small bronze figurine from Gran Carro site (Bolsena Lake, Italy)

This paper presents the results of an archaeometric analysis carried out on an early Iron Age anthropomorphic figurine discovered in the area of the Gran Carro on Bolsena Lake (Latium, Italy) site, currently interpreted as a place of worship. This statuette is considered a unicum, both because of the context in which it was found and because of its stylistic characteristics similar to those of bronzes from the Nuragic civilization (Sardinia, Italy). Its discovery and the data obtained from this work provide further evidence in support of numerous previous studies suggesting the presence of trade and direct exchanges between Sardinia and southern Etruria. The research was performed through some non-destructive investigations such as Energy Dispersive X-Ray Fluorescence (EDXRF) combined with Monte Carlo Simulation (MC) and micro-invasive investigations such as Scanning Electron Microscopy coupled by Energy Dispersive Spectroscopy (SEM–EDS) and by Electron Probe Micro-Analysis (EPMA), metallography and lead isotope analyses (LIA), performed on a selected micro-fragment. The combination of non-destructive techniques (EDXRF-MCS) for the characterization of the artefact allowed us to obtain data similar to those obtained with micro-invasive surveys, further demonstrating the effectiveness of the method. The results indicate that the statuette is made of a bronze alloy and that the copper metal was extracted from Sardinian deposits
