Severity of lung involvement on chest X-rays in SARS-coronavirus-2 infected patients as a possible tool to predict clinical progression: an observational retrospective analysis of the relationship between radiological, clinical, and laboratory data.

Objective: To investigate the diagnostic accuracy of a chest X-ray (CXR) score and of clinical and laboratory data in predicting the clinical course of patients with SARS coronavirus 2 (SARS-CoV-2) infection.

Methods: This is a pilot multicenter retrospective study including patients with SARS-CoV-2 infection admitted to the ERs in three hospitals in Italy between February and March of 2020. Two radiologists independently evaluated the baseline CXR of the patients using a semi-quantitative score to determine the severity of lung involvement: a score of 0 represented no lung involvement, whereas scores of 1 to 4 represented the first (less severe) to the fourth (more severe) quartiles regarding the severity of lung involvement.

[Our experience on the treatment of epigastric hernia].

The epigastric hernia represents a rare surgical affection, sometimes insidious, whose pathogenesis has been discussed for a long time, revealing, in the course of the years, multiple predisposing and responsible factors of its appearance. From our experience and the data reported in the literature, it is clear that a standard surgery does not exist for this pathology, and it is often necessary to perform preliminary uncommon diagnostic exams. Our retrospective study consists in the analysis of the surgical treatments executed, from 2003 to 2006, on 37 patients suffered from epigastric hernia, for everyone of which, on the basis of the clinical features, of the preoperative diagnostic results and of the characteristics of the hernia defect, it has been encouraged a personalized surgical procedure,obtaining therefore, for the same pathology, different treatment protocols (open or laparoscopic procedures, ordinary hospital stay or day-surgery, prosthetic or not surgical repair).

[The use of dermic substitutes in the repair of cutaneous defect due to a phlebostatic wound].

The use of dermic substitutes is a valid and effective choice in the treatment of the cutaneous defects with loss of substance. In our experience, the aesthetic and functional results of dermic substitutes is really positive and encouraging, with better tolerance by patients than the autologue grafts.

Peritoneal malignant mesothelioma: case report.

Our study reports peritoneal diffuse malignant mesothelioma (DMM) in a 43 years old male patient, with no exposure to asbestos in his medical history; the partner of the patient was also not exposed to asbestos. The exposure to X-rays was also excluded. Different pathogenic mechanisms for the pathogenesis of a peritoneal diffuse malignant mesothelioma in this patient can be hypothesized, for example, SV40 infection and genetic susceptibility; a minimal domestic exposure to asbestos can be not excluded.

Pathological evaluation in colorectal polyps endoscopic treatment.

This retrospective study shows that endoscopic polypectomy is the technique of choice to remove the majority of polyps; follow-up and pathologic examinations shed light on the carcinogenesis of colorectal lesions. From January 1990 to December 2001, 1302 adenomatous polyps were removed, 1175 endoscopically, 127 with surgical procedures. The anatomical and morphologic conditions of the colon and some characteristics of the polyps represent limits to the feasibility and to the efficacy of polypectomy, and the most important variables for the correct management of the patients affected by colorectal adenomatous polyps.
