Evaluation of the relationship between retinal nerve layer thickness and corpus callosum atrophy in MRI with memory impairment in patients with multiple sclerosis.

Introduction: Multiple sclerosis (MS) is a chronic neurological disease in which demyelination and loss of axons lead to disruption of communication between neurons in the central nervous system. Cognitive impairment occurs in a significant proportion of patients with MS. Therefore, the aim of this study was to investigate the relationship between retinal nerve fiber layer (RNFL) thickness and corpus callosum atrophy in magnetic resonance imaging with memory disorders in patients with MS.

Epidemiological and clinical risk factors related to severe COVID-19 in Iran: a multi-center study.

Background: Iran was one of the first countries to be affected by COVID-19. Identifying factors associated with the severity of COVID-19 is effective in disease management. This study investigated the epidemiological and clinical features and factors related to the severity of COVID-19 in one of the less privileged areas in Iran.

Diagnostic Accuracy of 18F-FDG-PET/CT and MRI in Predicting the Tumor Response in Locally Advanced Cervical Carcinoma Treated by Chemoradiotherapy: A Meta-Analysis.

Objective: The aim of this meta-analysis was to compare the diagnostic accuracy of 18F-FDG-PET/CT and MRI in predicting the tumor response in locally advanced cervical carcinoma (LACC) treated by chemoradiotherapy (CRT).

Method: This meta-analysis has been performed according to PRISMA guidelines. Systematic searches were conducted using PubMed and Embase databases for articles published from January 1, 2010, to January 1, 2020.

Comparison of renal arterial resistive index in type 2 diabetic nephropathy stage 0-4.

Chronic kidney disease (CKD) is one of world health problems and its prevalence and incidence is increasing. Chronic Kidney Failure involves a range of pathophysiologic processes that are associated with impaired renal function, leading to cardiovascular morbidity and mortality. Renal artery resistive index (RI) is indicator of atherosclerotic change in small vessels.

The Possible Associations of Nasal Septal Deviation with Mastoid Pneumatization and Chronic Otitis.

Background: The nasal septum deviation is the most common deformity of the nasal, and that can be congenital or acquired. Despite many studies exist about the impact of nasal septum deviation on chronic sinusitis and also association between chronic otitis and mastoid pneumatization; few studies exist about the impact of nasal septum deviation on chronic otitis and mastoid pneumatization.

Aim: The aim of this study was to evaluate the associations of nasal septum deviation and mastoid pneumatization and chronic otitis.

Seasonal variations of 25-OH vitamin D serum levels in Multiple Sclerosis patients with relapse using MRI.

An increasing body of evidence suggests that low vitamin D (25-[OH]-D) concentrations is linked to increased activity in multiple sclerosis (MS) patients and MS relapse. Therefore, the current study was aimed to evaluate vitamin D serum concentrations and its possible seasonal variations among MS patients with relapse. This prospective, descriptive study was conducted on patients with MS relapse who referred to the neurology center of Ali ibn Abi Talib Hospital in Zahedan during one year.

Comparison of intima-media thickness of common and internal carotid arteries of patients with ischemic stroke and intracerebral hemorrhage.

Background: Role of atherosclerosis in the pathogenesis of ischemic and hemorrhagic infarctions is still matter of debate. Intima-media thickness (IMT) of the common carotid artery (CCA) and internal carotid artery (ICA) are markers of atherosclerosis. The aim of this study was to compare CCA IMT and ICA IMT of patients with ischemic and hemorrhagic infarction.
