Repair of an anteroinferior glenoid defect by the latarjet procedure: quantitative assessment of the repair by computed tomography.

Purpose: The purpose of this study was to determine quantitatively whether the Latarjet procedure (coracoid transfer to the glenoid) is sufficient to restore a significant defect area of the glenoid.

Methods: Fourteen cadaveric shoulders were used (mean age, 76 years; range, 72 to 87 years). An anteroinferior glenoid defect was created and then the coracoid osteotomized to its angle and transferred to the defect.

Thrombosis and recanalization of straight sinus.

We describe a case of a 14-year-old boy who presented to the emergency department with nausea, vomiting, headache, and mental status changes. Noncontrast computed tomography scan of the brain in the emergency department revealed bilateral thalamic and striatocapsular infarcts. The patient was diagnosed with possible thrombosis of the thalamostriate veins, which was confirmed with urgent magnetic resonance venography (MRV).

Liver, bone marrow, pancreas and pituitary gland iron overload in young and adult thalassemic patients: a T2 relaxometry study.

Thirty-seven patients with beta-thalassemia major, including 14 adolescents (15.2 +/- 3.0 years) and 23 adults (26.

Acute pulmonary embolism: correlation of CT pulmonary artery obstruction index with blood gas values.

Objective: The purpose of our study was to investigate the relation between the pulmonary artery obstruction index assessed with helical CT and impairment in blood gases in patients with acute pulmonary embolism.

Subjects And Methods: Helical CT pulmonary angiography was performed in 78 patients who were suspected of having acute pulmonary embolism and selected as being free of underlying cardiopulmonary disease. Findings consistent with acute pulmonary embolism were observed in 34 patients.

Spontaneous intracranial hypotension: morphological findings and CSF flow dynamics studied by MRI.

We report on a case of spontaneous intracranial hypotension (SIH) presenting with classic MR findings, such as diffuse smooth thickening and intense contrast enhancement of the dura matter, increased size of the pituitary gland and downward displacement of the brain. In this case an engorgement of the cavernous sinuses is reported as an additional imaging finding of SIH. Moreover, phase-contrast MR study of the CSF flow dynamics revealed at the level of the aqueduct a decrease of the systolic and diastolic flow volume of CSF.

The clinical significance of aortic compliance and its assessment with magnetic resonance imaging.

The biophysical properties of the aortic wall seems to play a significant role in the pathogenesis of cardiovascular disease such as atherosclerosis, hypertension, aneurysm formation, Marfan's syndrome, and in normal aging. The presence and the proportion of smooth muscle, collagen, and elastin proteins contribute to the compliance of the vessel wall with the latter being the most extensible component. However, elastin fibers fracture at low stresses contributing to a decrease of the aortic compliance and consequently to an elevation of the pulse pressure, which is a risk factor of cardiovascular disease.
