Exploring the Role of Hormones and Cytokines in Osteoporosis Development.

The disease of osteoporosis is characterized by impaired bone structure and an increased risk of fractures. There is a significant impact of cytokines and hormones on bone homeostasis and the diagnosis of osteoporosis. As defined by the World Health Organization (WHO), osteoporosis is defined as having a bone mineral density (BMD) that is 2.

Chest computed tomography findings of 1271 patients with COVID-19 pneumonia and classifications with different age groups: a descriptive study from Istanbul, Turkey.

Objective: The objectives of this study were to describe lung computed tomography findings of patients with COVID-19 diagnosed by real-time reverse transcription polymerase chain reaction test, investigate whether the findings differ regarding age and gender, and evaluate the diagnostic performance of chest computed tomography based on the duration of symptoms at the time of presentation to the hospital.

Methods: From March 11 to May 11, 2020, 1271 consecutive patients (733 males and 538 females) were included in this retrospective, cross-sectional study. Based on age, patients were divided into five separate subgroups.

Diagnostic performance of thorax CT in mildly symptomatic COVID-19 patients: The importance of atypical CT findings.

Objective: Computed tomography of the thorax (Thorax CT) is frequently used to diagnose viral pneumonia in moderate to severe COVID-19 patients, but its diagnostic performance in mildly symptomatic COVID-19 patients is still unclear. Assessing the diagnostic performance of thorax CT in mildly symptomatic COVID-19 patients was the purpose of our study.

Methods: Mildly symptomatic and clinically stable, suspected COVID-19 patients scanned with Thorax CTs between March 11, 2020, and April 13, 2020, were included in this study.

Illumination of The Relationship between Ureter and Intervertebral Disc by Computed Tomography.

Aim: To show the relationship of lumbar intervertebral discs with the ureters by using computerized tomography (CT).

Material And Methods: Eighty patients (male/female: 42/38) with a mean age of 45 years were included in this retrospective study. An imaginary line passing through the tangential to the posterior cortex of the vertebral body was drawn at the intervertebral disc level (line a).

Measurement of spinal root angle at spinal canal and foraminal levels in cases of facet arthropathy: T2-weighted turbo spin echo magnetic resonance myelography with SPACE technique.

Background: Magnetic resonance myelography (MRM) with three-dimensional (3D) T2-weighted (T2W) turbo spin echo (TSE) sampling perfection with application-optimized contrasts using different flip angle evolution (SPACE) may be a guide to the etiology of low back pain.

Purpose: To research the efficiency of a 3D T2W TSE SPACE MRM sequence for visualization of anatomic details of spinal nerve root at the spinal canal and lateral recess levels in the patients with low back pain.

Material And Methods: Lumbar spinal MRM 3D T2W TSE SPACE was performed in a total of 70 patients (median age 46 years).

Bone Deformities as a Complication of Giant Thoracic Aortic Aneurysm.

The contained rupture of thoracic aortic aneurysm and related bone deformities is a rare condition. The diagnosis is critical due to potential and fatal complications. Radiologic evaluation is required to show the location, extension, and complications.
