Aortic root abscess is a common complication of aortic valve endocarditis. However, aortic root abscess and formation of a fistula from the aortic root to the right ventricular outflow tract in the setting of a native aortic valve and previous repair of an aortic dissection with a Dacron graft is an uncommon event. Transesophageal echocardiography is superior to transthoracic echocardiography f...

The integrity of the meniscal root insertions is fundamental to preserve correct knee kinematics and avoid degenerative changes of the knee. Injuries to the meniscal attachments can lead to meniscal extrusion, decreased contact surface, increased cartilage stress, and ultimately articular degeneration. Recent and well designed studies have clarified the anatomy and biomechanics of the medial an...

Aortic root dilatation is rare in children, and is often secondary to Marfan syndrome (MFS). We experienced a case of a three-year-old boy (92 cm, 12 kg) with MFS presenting with progressive dilatation of aortic root. We electively performed a valve-sparing aortic root replacement using a 24-mm Gelweave Valsalva graft. Although the patient required a mitral valve repair due to infective endocar...

This systematic review identified and qualified the current evidence of dental root damage and repair after contact with mini-implants. The electronic databases Cochrane library, Ovid, Scirus, Scopus, and Virtual Health Library were used to search original articles from 1980 to December 2011. The inclusion criteria to select the articles were 1. randomized controlled trials and prospective clin...

background currently, clinical endodontics includes procedures that are based on the ability of stem cells to accomplish repair (eg, direct pulp capping, apexogenesis, apexification, and even pulpal regeneration). an attempt is made to critically assess the current status in pulp regeneration therapy. methods: systematically, 2 distinctly different strategies exist involving stem cells for the ...
