Prenatal ultrasound detection of fetal amniotic band ingestion in monochorionic diamniotic twin pregnancy: a rare case report.

Background: Amniotic Band Syndrome (ABS) is a rare congenital condition characterized by the formation of fibrous bands within the amniotic sac that can entangle and restrict fetal development, leading to various deformities. In this report, we present an unprecedented case of fetal amniotic band ingestion in a monochorionic diamniotic (MCDA) twin pregnancy. Reporting this case is essential for expanding the understanding of the diverse presentations of amniotic bands, considering this rare entity in the differential diagnosis of prenatal ultrasound findings, and emphasizing the importance of vigilant prenatal monitoring and individualized management strategies.

Diagnostic Accuracy of Multiple MRI Parameters in Dealing with Incidental Thyroid Nodules.

Background: Different MRI parameters have been studied for evaluating thyroid nodules. Diffusion-weighted imaging (DWI) and T2 imaging sequences with considerable efficacy in evaluating soft tissue tumors merit further assessment for thyroid nodule investigation.

Method: We evaluated incidental thyroid nodules (ITNs) reported on head and neck MRI studies.

Evaluation of early complications, outcome, and mortality in Coronavirus Disease 2019 (COVID-19) infection in patients who underwent orthopedic surgery.

Background: A higher mortality and morbidity rate has been reported in COVID-19 patients undergoing surgery. To reduce the morbidity and mortality rate in COVID-19 patients undergoing orthopedic procedures, we aimed to increase the threshold for surgical planning.

Methods: In a prospective cohort study, COVID-19 patients who underwent elective or emergent orthopedic surgery in three orthopedic surgery centers from February 2020 to September 2020 were included.

Prediction of thyroid nodule malignancy using thyroid imaging reporting and data system (TIRADS) and nodule size.

Objectives: Thyroid imaging reporting and data system (TIRADS) is a combination of ultrasonographic features developed to help physicians in predicting the malignancy risk of thyroid nodules based on sonographic characteristics. Thyroid nodule size is another factor in determining whether a nodule is malignant. The aim of this study was detecting the predictive value of TIRADS and nodule size based on Bethesda classification in prognostication of malignancy.

Five-Year Case Fatality Following First-Ever Stroke in the Mashhad Stroke Incidence Study: A Population-Based Study of Stroke in the Middle East.

Background And Purpose: Despite recent declines in stroke mortality in high-income countries, the incidence and mortality of stroke have increased in many low- and middle-income countries. Population-based information on stroke in such countries is a research priority to address this rising trend. This study was designed to evaluate 5-year stroke mortality and its associated factors.

Five-Year Recurrence Rate and the Predictors Following Stroke in the Mashhad Stroke Incidence Study: A Population-Based Cohort Study of Stroke in the Middle East.

Background: Little is known about the risk of recurrent stroke in low- and middle-income countries. This study was designed to identify the long-term risk of stroke recurrence and its associated factors.

Methods: From November 21, 2006 for a period of 1 year, 624 patients with first-ever stroke (FES) were registered from the residents of 3 neighborhoods in Mashhad, Iran.

One-year case fatality rate following stroke in the Mashhad Stroke Incidence Study: a population-based study of stroke in Iran.

Background: In developing countries, there are few comprehensive studies of mortality following stroke.

Aims And/or Hypothesis: We aimed to determine the one-year case fatality rate following stroke and to identify factors associated with death in a population-based stroke incidence study in Iran.

Methods: Six hundred eighty-four patients who had suffered a stroke between November 21, 2006, and November 20, 2007, and were recruited to the Mashhad Stroke Incidence Study were followed up at one-year.

Characterization of a novel nanobiomaterial fabricated from HA, TiO and AlO powders: an in vitro study.

For the purposes of this study, hydroxyapatite (HA)-AlO-TiO nanobiomaterial with significant surface properties and biocompatibility capable of forming surface apatite was fabricated by cold-press and sintering method. Samples were examined for hardness and porosity. The results showed that in terms of hardness and porosity, sample A (50 wt% TiO-30 wt% HA-20 wt% AlO) was superior to sample B (30 wt% TiO-50 wt% HA-20 wt% AlO), and also the density of nanobiomaterial was close to natural bone density.

Clinical features of HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP) in northeast Iran.

This study aimed to introduce clinical manifestations of patients in northeast Iran with HTLV-1-associated myelopathy/tropical spastic paraparesis (HAM/TSP) and describe the epidemiological features, as well as risk factors for HTLV-1 infection. This is a cross-sectional study of HTLV-1 infected cases and HAM/TSP patients referred by outpatient neurology clinics as well as Mashhad Blood Transfusion Center from 2005 to 2010. The study comprises 513 cases, including 358 healthy carriers (HCs) and 145 HAM/TSP patients.

The impact of interferon-alpha treatment on clinical and immunovirological aspects of HTLV-1-associated myelopathy in northeast of Iran.

Human T-lymphotropic virus type 1 (HTLV-1)-associated myelopathy/tropical spastic paraparesis (HAM/TSP) is a chronic inflammatory myelopathy. The pathophysiology of HAM/TSP is not yet fully understood; therefore, effective therapy remains a challenging issue. This study was designed to evaluate the efficacy of interferon-alpha (IFN-α) in HAM/TSP patients in the Northeast of Iran.
