Epicardial adipose tissue (EAT) thickness on non-gated chest CT as an alternative to EAT volume on cardiac CT.

Background: Epicardial adipose tissue (EAT) volume is usually measured with ECG-gated computed tomography (CT). Measurement of EAT thickness is a more convenient method; however, it is not clear whether EAT thickness measured with non-gated CT is reliable and at which localization it agrees best with the EAT volume.

Purpose: To examine the agreement between ECG-gated EAT volume and non-gated EAT thickness measured from various localizations and to assess the predictive role of EAT thickness for high EAT volume.

Revisiting Pentacam Parameters in the Diagnosis of Subclinical and Mild Keratoconus Based on Different Grading System Definitions.

Objectives: To retest the performance of Pentacam parameters in the detection of eyes with subclinical keratoconus (KC) and mild KC based on different definitions from the Amsler-Krumeich (AK), Collaborative Longitudinal Evaluation of Keratoconus (CLEK), and ABCD systems.

Materials And Methods: This cross-sectional university-based study comprised 24 eyes with subclinical KC, 144 eyes with mild KC (based on AK in 101 eyes, CLEK in 28 eyes, and ABCD in 15 eyes), and 70 controls. Diagnostic ability of the thinnest point (TP) pachymetry, KISA% index, inferior-superior asymmetry, corneal aberrations, Pentacam indices, front/back elevations, pachymetric progression index, Ambrósio-Relational Thickness (ARTmax), and Belin/Ambrósio Enhanced Ectasia Display scores (Df, Db, Dp, Dt, Da, and D-final) were evaluated.

Increased epithelial backscatter: A novel finding in subclinical and clinical keratoconus.

Background: To assess alterations in backscatter from the corneal epithelium, anterior stroma and lens surface in eyes with subclinical, mild and moderate keratoconus (KC).

Methods: In this single-centre, cross-sectional study involving 24 eyes with subclinical KC, 107 eyes with manifest KC (mild = 40 and moderate = 67 eyes) and 90 controls, line densitometry was performed with Pentacam (Oculus Optikgeräte GmbH, Wetzlar, Germany) to obtain simultaneous backscatter values for the corneal epithelium, anterior stroma and anterior lens surface. Backscatter values and Pentacam parameters were used in subsequent statistical analyses.

Severe Intraocular Inflammation following Hydrophilic Acrylic Phakic Intraocular Lens Implantation in A Case with Concealed History of COVID-19: A Case Report and Literature Review.

: To firstly present management of toxic anterior segment syndrome (TASS) and possible postoperative endophthalmitis (POE) after implantation of a new hydrophilic-acrylic posterior chamber (PC) phakic intraocular lens (pIOL) in a case with undeclared history of COVID-19. A 21-year-old male without known disease represented severe anterior chamber inflammation (hypopyon), poor vision and corneal edema without vitreous involvement (TASS) at 24-hours after PC-pIOL implantation for unilateral high myopia (amblyopic). Preoperative best-corrected visual acuity (BCVA) was 0.

The role of pleural fluid thiol/disulphide homoeostasis in the differentiation between transudative and exudative pleural effusions.

Objective: In the present study, we aimed to differentiate between transudative and exudative pleural effusions using thiol sulphide homoeostasis, an oxidative stress marker.

Design: This was a prospective study.

Setting: Emergency Department of Ankara City Hospital, between 1 January 2020 and 15 May 2020.

How has Covid-19 pandemic affected crowded emergency services?

Objective: We aimed to investigate the demographic shifts in emergency service admissions, possible measures and room for improvement in emergency services during the Covid-19 pandemic.

Methodology: Our study retrospectively analysed the demographic features and clinical admission types of patients admitted to Batman District State Hospital Emergency Service at two different time periods, one between 28 March 2019 and 28 April 2019 (prior to the Covid-19 pandemic) and the other between 28 March 2020 and 28 April 2020 (during the Covid-19 pandemic). The results were compared between the two periods designated as the pandemic period and the pre-pandemic period.

Retrospective analysis of asymptomatic COVID-19 patients presenting to emergency department.

Objective: In this study, we aimed to investigate the clinical and demographic characteristics of asymptomatic COVID-19 cases incidentally diagnosed at the emergency department.

Methodology: This study retrospectively analysed the medical data of patients who presented to the emergency department, between March 1 and May 1, 2020, without COVID-19 symptoms such as fever, cough, myalgia on admission but were incidentally detected to have thoracic computerised tomography (CT) findings suggestive of COVID-19. The patients' sociodemographic and epidemiological characteristics, laboratory test results, clinical and radiological findings, treatment protocols and prognoses were recorded.
