Coronary and total thoracic calcium scores predict mortality and provides pathophysiologic insights in COVID-19 patients.

Background: Coronavirus disease 2019 (COVID-19) has spread worldwide determining dramatic impacts on healthcare systems. Early identification of high-risk parameters is required in order to provide the best therapeutic approach. Coronary, thoracic aorta and aortic valve calcium can be measured from a non-gated chest computer tomography (CT) and are validated predictors of cardiovascular events and all-cause mortality.

Treatment of hemorrhoids in day surgery: stapled hemorrhoidopexy vs Milligan-Morgan hemorrhoidectomy.

Background: Recently, it has been demonstrated that surgical treatment of hemorrhoids in a day-care basis is possible and safe. The aim of this study was to compare the Longo stapled hemorrhoidopexy (SH) and the Milligan-Morgan hemorrhoidectomy (MMH).

Methods: One hundred seventy one patients (95 cases in SH group and 76 cases in MMH group) entered the study: 83 cases were III degree hemorrhoids, 88 IV degree.

Massive intestinal infarction following retroperitoneoscopic right lumbar sympathectomy.

The adverse physiological effects of pneumo and retro-peritoneum are relatively well known. However, the clinical implications of compromised mesenteric circulation through several mechanical and physiological mechanisms are not as well recognized. We describe a fatal case of intestinal infarction following an elective retroperitoneoscopic right sympathectomy.
