Case Report: A Peculiar Case of Inflammatory Colitis After SARS-CoV-2 Infection.

We report a case of inflammatory colitis after SARS-CoV-2 infection in a patient with no additional co-morbidity who died within three weeks of hospitalization. As it is becoming increasingly clear that SARS-CoV-2 infection can cause immunological alterations, we investigated the expression of the inhibitory checkpoint PD-1 and its ligand PD-L1 to explore the potential role of this axis in the break of self-tolerance. The presence of the SARS-CoV-2 virus in colon tissue was demonstrated by qRT-PCR and immunohistochemical localization of the nucleocapsid protein.

ERANET JTC 2011: Submission and Activation of an International Academic Translational Project in Advanced Breast Cancer. Experience From the ET-FES Study.

Academic research is important to face unmet medical needs. The Oncological community encounters many hurdles in setting up multicenter investigator-driven trials mainly due to administrative complexity. The purpose of a network organization at a multinational level is to facilitate clinical trials through standardization, coordination, and education for drug development and regulatory approval.

Percutaneous trans-hepatic rescue and neo-creation of a post-surgical complete hepaticojejunostomy dehiscence.

Biliary leakage complicating hepaticojejunostomy is a therapeutic dilemma for surgeons, gastroenterologist, and interventional radiologist. It is a major cause of postoperative morbidity. Percutaneous biliary intervention techniques have been developed for treating benign post-surgical biliary disease in patients not having severely compromised clinical conditions.

Rare anti-VEGFR therapy-induced toxicity and long-term response to immunotherapy in a rare non-clear cell renal cell carcinoma patient.

Advanced non-clear cell renal cell carcinoma (nccRCC) has a poor prognosis and clinical data on the therapeutic options currently available, including immunotherapy, are generally limited highlighting an unmet clinical need. Moreover, the onset of rare adverse events raises the need of a better therapeutic management of limited treatment options. We report the clinical case of a 63-year-old man with the diagnosis of metastatic mucinous tubular and spindle cell carcinoma, a rare nccRCC, with sarcomatoid differentiation who developed two episodes of posterior reversible encephalopathy syndrome (PRES) to first-line sunitinib.

Hypersensitivity reactions to iodinate contrast media in Italy: a retrospective study. Characteristics of patients and risk factors.

The purpose of the study was to describe the characteristics of patients experiencing hypersensitivity reactions (HRs) to iodinated contrast media (ICM) in a large Italian population and to investigate potential risks factors in order to obtain a risk stratification, helpful in the management of these patients. Data of 407 patients investigated in 9 Italian Allergy Centers for suspected HRs to ICM were analyzed and compared with a control group of 152 subjects that tolerated one or more ICM-enhanced examinations. The univariate and multivariate logistic regression model was used to evaluate associated factors.

Heterogeneity of bone metastases as an important prognostic factor in patients affected by oestrogen receptor-positive breast cancer. The role of combined [18F]Fluoroestradiol PET/CT and [18F]Fluorodeoxyglucose PET/CT.

Purpose: To assess the prognostic role of different inter and intralesional expression (heterogeneity) of oestrogen receptor (ER) in bone metastases, as identified by the combined use of [18F]FES PET/CT and [18F]FDG PET/CT in patients with oestrogen receptor-positive (ER+) metastatic breast cancer (BC).

Methods: We analysed patients with a new diagnosis of bone metastases who were candidates for first-line systemic endocrine therapy. Before starting therapy, patients underwent baseline [18F]FES PET/CT and [18]FDG PET/CT.

Efficacy of early anti-inflammatory treatment with high doses of intravenous anakinra with or without glucocorticoids in patients with severe COVID-19 pneumonia.

Background: IL-1 plays a pivotal role in the inflammatory response during cytokine storm syndromes.

Objective: Our aim was to analyze the efficacy and safety of early anti-inflammatory treatment (AIT) with intravenous anakinra with or without glucocorticoids in coronavirus disease 2019 (COVID-19) pneumonia.

Methods: We performed a retrospective single-center cohort study of patients admitted for COVID-19 pneumonia from February 26 to April 29, 2020, to assess the efficacy of early AIT with intravenous anakinra (100 mg every 8 hours for 3 days, with tapering) alone or in combination with a glucocorticoid (intravenous methylprednisolone, 1-2 mg/kg daily, with tapering).

Contamination inside CT gantry in the SARS-CoV-2 era.

We investigated whether the internal gantry components of our computed tomography (CT) scanner contain severe acute respiratory syndrome 2 (SARS-CoV-2) ribonucleic acid (RNA), bacterial or fungal agents. From 1 to 27 March 2020, we performed 180 examinations of patients with confirmed SARS-CoV-2 infection using a dedicated CT scanner. On 27 March 2020, this CT gantry was opened and sampled in each of the following components: (a) gantry case; (b) inward airflow filter; (c) gantry motor; (d) x-ray tube; (e) outflow fan; (f) fan grid; (g) detectors; and (h) x-ray tube filter.

Evaluation of novel coronavirus disease (COVID-19) using quantitative lung CT and clinical data: prediction of short-term outcome.

Background: Computed tomography (CT) enables quantification of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, helping in outcome prediction.

Methods: From 1 to 22 March 2020, patients with pneumonia symptoms, positive lung CT scan, and confirmed SARS-CoV-2 on reverse transcription-polymerase chain reaction (RT-PCR) were consecutively enrolled. Clinical data was collected.

Diagnostic value of retrospectively fused CuCl PET/MRI in biochemical relapse of prostate cancer: comparison with fused F-Choline PET/MRI, CuCl2 PET/CT, F-Choline PET/CT, and mpMRI.

Purpose: To assess the diagnostic value of retrospectively fused PET/MRI by comparing the detection rates (DRs) of fused CuCl PET/MRI vs. fused F-Choline PET/MRI in patients with suspected prostatic cancer (PCa) recurrence. The secondary objective was to compare the DRs of fused PET/MRI vs.

Solitary Fibrous Tumor of the Prostate.

Even though most tumors located in the prostate derive from prostatic glands, there is a long list of malignant and nonmalignant causes for prostatic growths that clinicians should be aware of. Tumors of the prostate can be grouped in epithelial, neuroendocrine, stromal, mesenchymal, hematolymphoid, and miscellaneous. Solitary fibrous tumor of the prostate (SFT), is an extremely rare mesenchymal tumor (only about 20 cases reported in the literature).

Noninvasive liver fibrosis assessment in chronic viral hepatitis C: agreement among 1D transient elastography, 2D shear wave elastography, and magnetic resonance elastography.

Purpose: To assess the agreement of one-dimensional transient elastography (1D-TE), two-dimensional shear wave elastography (2D-SWE), and magnetic resonance elastography (MRE) in a consecutive cohort of patients affected by hepatitis C virus (HCV) and to understand which patient-related factors are associated with disagreement.

Methods: Ninety-one consecutive patients with current or previous chronic HCV infection were enrolled between March 2017 and September 2018. We assessed the correlation between stiffness measurements expressed in kilopascals (kPa).

Horseshoe adrenal gland associated with spinal and vascular anomalies.

Horseshoe (or butterfly) adrenal gland (HAG) is an exceedingly rare congenital abnormality compared to horseshoe kidney. Here we present computed tomography findings of HAG in a 70-year-old man, associated with some spinal and vascular abnormalities; in addition, a brief review of HAG in adult people is presented. In our case, spinal anomalies included a severe scoliosis, a "butterfly" deformation of Th9 vertebra and the presence of a "split lumbosacral thecal sac" at L5 level.

Thoracic Renal Artery.

We report a case of right renal artery originating from the thoracic aorta with normal position of the right kidney. Although this anomaly is rare, vascular, thoracic, and urological surgeons should be aware about this vascular variant before planning their surgical intervention.

Spontaneous hepatic haemangioma rupture and hemoperitoneum: a double problem with a single stage interventional radiology solution.

Hepatic haemangioma is a congenital vascular malformation, considered the most common benign mesenchymal hepatic tumour. Spontaneous or traumatic rupture is the most severe complication. In case of rupture, surgical resection and enucleation, as a single therapy or after trans-arterial embolization are considered the treatments of choice.

Imaging findings of ovarian leiomyosarcoma with histopathologic correlations.

Leiomyosarcoma (LMS) is a malignant mesenchymal tumor deriving from smooth muscle. Ovarian LMS is exceedingly rare and only few reports have been reported in literature. The article illustrates a case of ovarian leiomyosarcoma in a 61-year-old woman, describing CT and MRI features correlated to histopathologic findings.

Right Iliac Artery-Inferior Vena Cava Arteriovenous Fistula.

This report describes a case of elderly patient with right iliac artery fissured pseudoaneurysm, leading to inferior vena cava arteriovenous fistula that was treated by covered stent device deployed at the level of the right iliac pathologic segment.

Materials and techniques for percutaneous retrieval of intravascular foreign bodies.

The presence of an intravascular foreign body represents a well-known risk of serious complications. While in the past surgical removal of intravascular foreign body was the most common intervention, nowadays a percutaneous approach in the retrieval of an intravascular foreign body is widely accepted as the first-line technique. In the literature, many case reports describe different techniques and materials.
