Combined Model of Quantitative Evaluation of Chest Computed Tomography and Laboratory Values for Assessing the Prognosis of Coronavirus Disease 2019.

Purpose: To assess the prognostic power of quantitative analysis of chest CT, laboratory values, and their combination in COVID-19 pneumonia.

Materials And Methods: Retrospective analysis of patients with PCR-confirmed COVID-19 pneumonia and chest CT performed between March 07 and November 13, 2020. Volume and percentage (PO) of lung opacifications and mean HU of the whole lung were quantified using prototype software.

Conspicuity of malignant pleural mesothelioma in contrast enhanced MDCT - arterial phase or late phase?

Background: To determine if late phase is superior to arterial phase intraindividually regarding conspicuity of MPM in contrast enhanced chest MDCT.

Methods: 28 patients with MPM were included in this retrospective study. For all patients, chest CT in standard arterial phase (scan delay ca.

Computed tomography characterization and outcome evaluation of COVID-19 pneumonia complicated by venous thromboembolism.

Background: COVID-19 is frequently complicated by venous thromboembolism (VTE). Computed tomography (CT) of the chest-primarily usually conducted as low-dose, non-contrast enhanced CT-plays an important role in the diagnosis and follow-up of COVID-19 pneumonia. Performed as contrast-enhanced CT pulmonary angiography, it can reliably detect or rule-out pulmonary embolism (PE).

Sharp margin and geographic shape: systematic evaluation of two novel CT features in COVID-19 pneumonia.

Objective: CT is important in the care of patients with COVID-19 pneumonia. However, specificity might be poor in the absence of a clinical and epidemiological context. The goal of this work was to systematically evaluate two novel CT features (sharp margin and geographic shape) of COVID-19 pneumonia.

Yellow nail syndrome: dystrophic nails, peripheral lymphedema and chronic cough.

A case involving a 41-year-old man with yellow nail syndrome (YNS) is reported. YNS is a rare disorder characterized by yellow, dystrophic nails, peripheral lymphedema and bronchiectasis with recurrent lower respiratory tract infections. YNS is often misdiagnosed because the syndrome is not well known.

Admission visfatin levels predict pancreatic and peripancreatic necrosis in acute pancreatitis and correlate with clinical severity.

Objectives: Adipocytes of peripancreatic and intrapancreatic adipose tissue secret adipocytokines such as leptin, adiponectin, and resistin. For resistin, a role as an early predictor of peripancreatic necrosis and clinical severity in acute pancreatitis has been reported. It was the aim of this study to investigate whether the adipocytokine visfatin is able to serve as an early marker predicting peripancreatic necrosis and clinical severity.

Delayed visceral arterial hemorrhage following Whipple's procedure: minimally invasive treatment with covered stents.

Background: Delayed visceral arterial hemorrhage caused by inflammatory vessel erosion represents a rare but life-threatening complication after pancreatic head resection. Therapeutic options include reoperation or endovascular minimally invasive techniques such as embolization or stent graft placement. The present article describes our experiences with implantation of newly developed low-profile stent grafts.
