pediatric mandibular fractures have been successfully managed in various ways. the use of a lingual splint is an option. this article presents a 4-year old boy who was treated by an alternative conservative method with a combination of an arch bar plus a lingual splint, circum-mandibular wiring and imf for the reduction, stabilization and fixation of a severely displaced bilateral man dibular b...
background vascular ring is less than 1% of congenital heart disease. double aortic arch (daa) is the most common form of it. its detecting is important because of the effects of pressure on the esophagus and trachea. case report in this study, three children suffering from double aortic arch with symptoms of dysphagia and recurrent aspiration, which in two cases had led to cardiac arrest, wer...
Background Abnormal aortic arch geometry, in particular the ‘gothic arch’, has been associated with reduced exercise performance in patients with repaired aortic coarctation. Following the arterial switch operation (ASO) for transposition of the great arteries (TGA), the morphology of the aorta is also known to be abnormal, presenting with dilated aortic root and ‘gothic’ deformity of the aorti...

Panel H. Posterior views of 3D VR imaging demonstrating that the branches of the aorta arch originate from the superior aortic arch.

Digital arch arteriography is a technique in which the cervicocerebral vasculature is studied by injecting small amounts of contrast material (20 ml or less of diatrizoate meglumine 60%) into the aortic arch. It was used as the initial phase of arteriography in 100 patients with cerebrovascular disease. Five to ten series were obtained in various projections to evaluate the cerebrovascular syst...
Results: The sample was composed of 176 patients: single angle fracture (n=47), angle with 1 non-angle fracture (n=118), angle with 2 non-angle fractures (n=10), and bilateral angle fractures (n=1). For all fractures, arch bar MMF was found to have significantly lower malocclusion rates than both manual reduction (2.8% vs 17.5%, p=0.01) and non-arch bar MMF (2.8% vs 13.3%, p=0.04). For patients...
وجود تغییرات ساختاری در سریهای زمانی مالی از عواملی است که موجب میشود مدلهای خطی برای تحلیل این سریها مناسب نباشند. نادیده گرفتن این تغییرات در سطح میانگین و واریانس سریهای زمانی اثرات نامطلوبی روی تحلیلها خواهد گذاشت. در بسیاری از سریهای زمانی مالی و اقتصادی فرض ثابت بودن واریانس برقرار نیست که در این شرایط مدلهای خانواده اتورگرسیو ناهمواریانس شرطی میتوانن نتایج مطلوبی ارائه دهند. در ای...
