Angiographic findings of pulmonary arterial involvement in Behcet's Disease: Do they correlate with symptoms and acute phase response?

Introduction: Behcet's disease (BD) is a chronic inflammatory disorder with arterial vasculitis. Although, pulmonary artery aneurysm (PAA) is accepted as the prototypic arterial disorder, an increasing presence of pulmonary artery thrombosis (PAT) with or without aneurysms was also reported in recent studies. In this study, we aimed to describe computed tomography pulmonary angiography (CTPA) findings of pulmonary involvement and its correlation with symptoms and acute phase response in BD.

New grading system for post-COVID-19 pulmonary fibrosis based on computed tomography findings.

Background: There is currently no objective computed tomography (CT)-defined grading system for coronavirus disease (COVID-19)-related pulmonary fibrosis. We propose a CT-based radiological scale that adapts the histological fibrosis scale to pulmonary fibrosis CT findings, to evaluate possible predictive factors for the degree of fibrosis in these patients.

Methods: A new radiological fibrosis grading system was created based on existing histological fibrosis scales.

Accuracy and reliability of magnetic resonance imaging in the diagnosis of idiopathic intracranial hypertension.

Purpose: To determine the diagnostic utility of brain magnetic resonance imaging (MRI) findings in patients with idiopathic intracranial hypertension (IIH) and to investigate the significance of evaluating radiological findings together with neurological and ophthalmological data in the diagnosis of IIH.

Materials And Methods: All consecutive patients diagnosed with IIH in our tertiary neuro-ophthalmology center between January 1, 2018 and March 15, 2020, were included in the study. The clinical, radiological, and ophthalmological findings of IIH patients were compared with the control group with similar demographic characteristics.

Comparison of SARS-COV-2 antibody assays in PCR negative and PCR positive Turkish patients.

Background: To the Editor, Serology may offer valuable information during COVID-19 pandemic; however, published papers mainly reported the results of symptomatic patients having positive RT-PCR on upper respiratory tract specimens [1]. More studies are needed to address whether asymptomatic patients, or patients with chest imaging compatible with COVID-19 but negative RT-PCR, have different antibody response that could influence assays performances. We wanted to share our data from Turkey where 4,323,596 COVID-19 cases were detected out of 44,087,628 PCR tests by April 20, 2021 but there are only a couple of published studies about serodiagnosis of the infection.

Materials And Methods: A total of 692 computed tomography pulmonary angiographies with PE were enrolled, and patients were grouped according to clot localization. Parenchymal findings, morphometric measurements of right heart function, and contrast reflux in IVC were noted.

Successful treatment of an invasive fungal infection caused by Talaromyces sp. with voriconazole.

Invasive fungal infections (IFI) are on the rise due to increasing numbers of immunosuppressed and critically ill patients. A malignant-looking pulmonary nodule in an immunosuppressed patient may indeed be caused by a fungal organism. We report a patient, who was eventually diagnosed with an IFI caused by an agent of hyalohyphomycosis, Talaromyces sp.

Diffusion-weighted MR imaging in postoperative follow-up: reliability for detection of recurrent cholesteatoma.

Introduction: Cholesteatoma is a progressively growing process that destroy the neighboring bony structures and treatment is surgical removal. Follow-up is important in the postoperative period, since further surgery is necessary if recurrence is present, but not if granulation tissue is detected. This study evaluates if diffusion-weighted MR imaging alone can be a reliable alternative to CT, without use of contrast agent for follow-up of postoperative patients in detecting recurrent cholesteatoma.

Transarterial microcatheter glue embolization of the bronchial artery for life-threatening hemoptysis: technical and clinical results.
