Frequency of typical and atypical computed tomography findings of COVID-19 and their effect on hospitalization.

Objective: This study aimed to determine the frequency of typical and atypical computed tomography (CT) findings of COVID-19 and their effect on hospitalization.

Methods: We retrospectively assessed 414 patients who were diagnosed with COVID-19 by real-time reverse transcription-polymerase chain reaction and who had lung involvement in their admission chest CT. We evaluated the frequency of typical and atypical chest CT findings and analyzed the relationship between typical and atypical findings of COVID-19 in patients treated in ambulatory versus inpatient settings.

Use of multiparametric magnetic resonance imaging as a screening tool for the determination of acute ischemic stroke duration.

Objective: This study aimed to assess the usability of magnetic resonance imaging (MRI) parameters in the treatment of stroke patients whose symptom onset time is unknown.

Patients And Methods: We evaluated MRI of the patients whose stroke symptoms began within 12-hours. For quantitative analysis, fluid-attenuated-inversion-recovery (FLAIR) and diffusion-weighted-imaging (DWI) signal-intensity-ratios (SIR) of the lesions were computed.

Predictive and prognostic role of mean platelet volume in patients with first-ever acute ischemic stroke.

Objective: To investigate any possible effects of mean platelet volume (MPV) on short-term stroke prognosis and functional outcome in patients with first-ever acute ischemic stroke (FEAIS).

Methods: This retrospective cross-sectional study included 798 FEAIS patients admitted to the emergency department of a tertiary care hospital in Adiyaman, Turkey between January 2013 and June 2015. The data were evaluated according to whether alive or dead, MPV levels, modified Rankin scale (MRS) scores, National Institutes of Health Stroke Scale (NIHSS) scores.

Unilateral right pulmonary agenesis in adulthood.

Congenital malformations of the lung, which may vary in degrees of severity, are very rare diseases. Pulmonary artery agenesis is a rare anomaly that may occur during the early involution of the proximal portions of the sixth aortic arch, during embryological development of the heart. This agenesis may be accompained by a complete or partial absence of the lung and its bronchus on the same side, which is diagnosed as pulmonary agenesis.

The limbic degradation of aging brain: a quantitative analysis with diffusion tensor imaging.

Introduction: The limbic system primarily responsible for our emotional life and memories is known to undergo degradation with aging and diffusion tensor imaging (DTI) is capable of revealing the white matter integrity. The aim of this study is to investigate age-related changes of quantitative diffusivity parameters and fiber characteristics on limbic system in healthy volunteers.

Methods: 31 healthy subjects aged 25-70 years were examined at 1,5 TMR.

Hydatid cyst of paravertebral muscle mimicking disc herniation.

Study Design: Case report.

Objective: To present a case of primary hydatid cyst in the lumbar subcutaneous tissue affecting posterior paravertebral muscle and mimicking disc herniation.

Summary Of Background Data: Cystic hydatid disease is a rare but significant parasitic disease in endemic areas.

Superior ophthalmic vein thrombosis developed after orbital cellulitis.

A 65-year-old female patient presented with eye pain, swelling and blurred vision in the left eye. Routine biochemistry and microbiological analyzes were conducted. Orbital tomography (CT), magnetic resonance imaging (MRI) findings, and cerebral angiography were performed.

The effects of G-CSF and naproxen sodium on the serum TGF-beta1 level and fracture healing in rat tibias.

Local and systemic release of transforming growth factor beta 1 (TGF-beta1) is known to increase during the process of fracture healing and this cytokine stimulates bone healing. The majority of the non steroidal anti inflammatory drugs (NSAIDs) inhibit fracture healing. Granulocyte colony stimulating factor (G-CSF) is a hematopoietic growth factor that stimulates bone marrow.

[Radiologic and morphologic evaluation of the lateral sacral mass].

Objectives: Morphologic measurements of the lateral sacral mass (LSM) and adjacent bone structures were made on dried sacrum specimens, together with radiologic evaluations on computed tomography (CT) scans in order to assess the appropriateness of this area in iliosacral screw applications.

Methods: On thirty dried human sacral bone specimens, morphologic measurements of the LSM were made by a compass sensitive to millimeters. Computed tomographic views of S1 and S2 pedicle-bodies and intervertebral foramina were obtained to make radiologic measurements by a millimeter-sensitive ruler to examine the relationship between LSM and the neural canal and intervertebral foramina.

Malignant melanoma of the soft parts showing calciphylaxis.

Calciphylaxis is a poorly understood and highly morbid syndrome of vascular calcification and skin necrosis. Hypercalcemia, hyperphosphatemia, and secondary hyperparathyroidism are the factors implicated in the pathogenesis of calciphylaxis, which is generally identified in patients with hyperparathyroidism secondary to end-stage renal disease. It has also been observed in primary hyperparathyroidism, end-stage liver disease, and rheumatoid arthritis, in the absence of renal disease.
