Effects of Obesity on Axillary Lymph Node Structure: Association of Hilar Fat Deposition and Alterations in Cortex Width.

This study aims to evaluate the effects of obesity on the structure of axillary lymph nodes in women with no evidence of breast or axilla pathology. In this prospective study, we documented the body mass index of 204 women who were referred for screening mammography. Two radiologists have independently viewed the mammograms to find the largest axillary lymph node and reported its dimensions.

Diagnostic value of shear wave sonoelastography in differentiation of benign from malignant thyroid nodules.

Purpose: To study the efficacy of shear wave elastography (SWE), using both qualitative and quantitative methods, alone and in conjunction with other B-mode features.

Method: 117 patients with 123 nodules were studied both by conventional ultrasonography and SWE. Size, echogenicity, margins, internal calcification (micro- or macro-calcification), composition, shape and color Doppler were assessed for each nodule.

Proximal Tibiofibular Joint Inclination Angle and Associated Meniscal Tear in Patients with Discoid Lateral Meniscus.

Discoid lateral meniscus (DLM) is the most common congenital variant of a meniscus with a high prevalence meniscal tear due to abnormal shape and behavior. The proximal tibiofibular joint (PTFJ) has an important role during knee extension and ankle dorsiflexion. The aim of this research is to study the association between PTFJ morphology in MRI and DLM and its pathologies as compared with the normal lateral meniscus in Iranian population.

Does the normal four steps weight-bearing rule predict the need for radiography in cases of blunt ankle trauma?

Ankle injuries are one of the most common complaints of patients presenting to emergency departments (ED). The Ottawa ankle rules (OAR) was introduced to help physicians to decide who may require x-ray for blunt injuries. The present study aimed at validating the four steps weight-bearing rule of OAR as a sole criterion.

Evidence-based prevention and treatment of osteoporosis after spinal cord injury: a systematic review.

Purpose: Spinal cord injury (SCI) results in accelerated bone mineral density (BMD) loss and disorganization of trabecular bone architecture. The mechanisms underlying post-SCI osteoporosis are complex and different from other types of osteoporosis. Findings of studies investigating efficacy of pharmacological or rehabilitative interventions in SCI-related osteoporosis are controversial.

Developing SNOMED-CT for decision making and data gathering: a software prototype for low back pain.

The issue of medical errors is currently a global concern which places a heavy financial and emotional burden on communities. A clinical decision support system (CDSS) is an electronic system designed to support clinical decision making. Considering the increasing importance and use of Systematized Nomenclature of Medicine-Clinical Terms (SNOMED-CT), we developed SNOMED-CT to implement it more efficiently in making smart history taking, decisions to perform lab tests and imaging, diagnosis and recommendations.

Preventing motor vehicle crashes related spine injuries in children.

Background: Spinal cord injury (SCI) is a devastating event that results in permanent disability for injured children. Among all etiologies of SCI, motor vehicle crashes (MVCs) are the leading cause and account for 29% of all traumatic SCIs in children. We tried to evaluate types and mechanisms of MVC-related spinal column and spinal cord injuries, risk factors, safety issues and legislation.
