Can pelvic diameter measurement have an effect on surgical outcomes in radical cystectomy?

Objective: To determine the effectiveness of pelvis diameters in determining postoperative outcomes in men who underwent open radical cystectomy + urinary diversion, it is aimed to predict the factors that may affect the operative difficulty and possible surgical outcomes before the operation.

Methods: A total of 79 radical cystectomy patients operated in our institution with preoperative computed tomography (CT) were included the study. Pelvic dimensions; symphysis angle (SA), upper conjugate, lower conjugate, pelvic depth, apical depth (AD), interspinous distance (ISD), bone femoral width and soft tissue width were measured by preoperative CT.

The value of dual-energy computed tomography in the evaluation of myocarditis.

Purpose: The inflammation of the heart muscle is referred to as acute myocarditis. Cardiac magnetic resonance imaging (CMR) has become the primary method for a non-invasive assessment of myocardial inflammation. However, there are several drawbacks of CMR.

Dynamic thiol-disulphide homeostasis as a biomarker for predicting the development of contrast medium-associated acute kidney injury in the endovascular treatment of peripheral arterial disease: should intravenous N-acetylcysteine be given before the procedure?

Aim: To determine the predictive ability of serum thiol-disulphide levels for contrast medium-associated acute kidney injury (CA-AKI) after endovascular treatment (EVT) of peripheral arterial disease (PAD) and evaluate the efficacy of intravenous N-acetylcysteine (NAC) in preventing CA-AKI.

Material And Methods: This double-blind, randomised controlled study included 85 consecutive adult patients who underwent EVT for PAD. Patients were divided into NAC negative (NAC-) and positive (NAC+) groups.

Bilateral Conjugating Carotid Body Tumor and Associated Jugular Vein Aneurysm.

Carotid body tumors (CBTs) originate from the paraganglionic tissue in the bifurcation of the common carotid artery. Magnetic resonance (MR) imaging is a commonly used diagnostic method in the preoperative diagnosis of these tumors. In this study, we demonstrated an isthmus between the right and left carotid body tumors in a patient with bilateral CBT.

Magnetic resonance imaging findings in COVID-19-related anosmia.

Background: The coronavirus disease 2019 (COVID-19) mostly manifests with fever, shortness of breath, and cough, has also been found to cause some neurological symptoms, such as anosmia and ageusia. The aim of the study was to present the magnetic resonance imaging (MRI) findings of patients with anosmia-hyposmia symptoms and to discuss potential mechanisms in light of these findings.

Methods: Of the 2412 patients diagnosed with COVID-19-related pneumonia (RT-PCR at least once + clinically confirmed) between March and December 2020, 15 patients underwent olfactory MRI to investigate the cause of ongoing anosmia/ hyposmia symptoms were included in the study.
