Ectopic eruption of the mandibular permanent lateral incisors involving the loss of the adjacent primary canines is not uncommon, yet the extreme distalization and transposition of such teeth (partial or true) has been reported infrequently. Three cases that illustrate various anomalous eruption-exfoliation patterns are presented. Theories that attempt to explain the etiology of anomalous erupt...
OBJECTIVES We appraised the incidence and clinical outcomes of patients who were treated with the valve-in-valve (ViV) technique for hemodynamically destabilizing paraprosthetic leak (PPL). BACKGROUND Device malpositioning causing severe PPL after transcatheter aortic valve implantation is not an uncommon finding. It occurs after release of the prosthesis, leading to hemodynamic compromise. I...
introduction: stereotactic radiosurgery is a technique for the treatment of intracranial lesions with highly collimated x-ray beam. linac-based radiosurgery is currently performed by two techniques: couch or pedestal mounted. in the first technique, a device is required to affix patient's head to a couch and moreover to translate it accurately. structure of...
total anomalous pulmonary venous connection (tapvc) is an anomaly in which the pulmonary veins are directly connected to one of the systemic veins or drain into the right atrium. management of pulmonary hypertension after the total correction of this congenital cardiac anomaly is very important. unligation of the vertical vein in the supracardiac type of this anomaly can be a draining pathway f...

Dentinal dysplasia type 1 is a rare herediatary disease which is attributed to an automosal dominant trait. It's incidence is about 1: 100.000. Both dentition are affected with, although the involved teeth have a normal size, shape and consistency, and they are occasionally amber. The most common clinical feature, due to their extreme mobility, is malalignement and malpositioning of teeth. Such...
Compartment syndrome is a serious condition characterized by raised intracompartmental pressure, which develops following trauma. Well leg compartment syndrome (WLCS) is a term reserved for compartment syndrome in a nontraumatic setting, usually resulting from prolonged lithotomy position during surgery. In literature, 8 cases have been reported regarding well leg compartment syndrome in a supi...
Symptomatic scapular winging resulting in scapular dyskinesia leads to a wide spectrum of clinical complaints, most notably periscapular pain. The malpositioning of the scapula, termed through use of the acronym SICK (scapular malposition, inferior-medial border prominence, coracoid pain and malposition, and dyskinesia of scapular movement), is due to the irregular activity of one or more of th...
Computer assisted surgery navigation takes full advantage of progress in engineering disciplines. Developed models increase the accuracy of replacement technique, especially in hip surgery to reduce the risk of component malpositioning. This paper presents a 3D model reconstruction from contour extracted through a proposed multi-agent segmentation (MAS) approach. We first describe parallel agen...
