BACKGROUND The presence of calcified atherosclerosis in different vascular beds has been associated with a higher risk of mortality. Thoracic aorta calcium (TAC) can be assessed from computed tomography (CT) scans, originally aimed at coronary artery calcium (CAC) assessment. CAC screening improves cardiovascular risk prediction, beyond standard risk assessment, whereas TAC performance remains ...

A biomechanical in vitro study was performed on 16 fresh frozen cadaver forearms to investigate the role of the transverse carpal ligament (TCL) in carpal stability. The distance between the scaphoid and hamate was measured, as a reference for the length of the TCL. Distances were recorded in both loaded and unloaded conditions after gradual sectioning of the transverse carpal ligament, the pal...

PURPOSE The purpose of this study was to consider the available evidence regarding premature loss of primary molars and the implications for treatment planning. METHODS Electronic database searches were conducted--including published information available until July 2007--for available evidence. A methodological quality assessment was also applied. RESULTS Although a significant number of p...

The condition to be described was discovered during routine dissecting-room work in a man aged 88, who had no history of any illness during life, and whose death was due to bronchopneumonia. The left subclavian and internal jugular veins united in the neck to form a left superior vena cava which passed directly down over the arch of the aorta and the pulmonary trunk to lie between the left auri...

The purpose of this study was to demonstrate 1)the joint couple of foot-shank complex in the kendo motion and 2)the relationship between the kinematic values and the foot arch height. Seventeen experienced kendo athletes volunteered to participate in the study. We instructed the participants to perform three sets of kendo strike-thrust motion with the distance of 2.2m to the target. We obtained...

We report on a 37-year-old woman with essential systemic hypertension. An MRI was performed because of weak femoral pulses, depicting a severe almost atretic coarctation of the aorta (Fig. 1). Angiography of the proximal distal thoracic aorta was simultaneously performed (Fig. 2a). The transverse arch was narrow (16 mm), as was the diameter of the terminal aortic arch distal to the left subclav...

Nineteen infants with suspected coarctation of the aorta were studied with electrocardiographically gated magnetic resonance imaging on a 1.5 T whole body imaging system. In all cases imaging was successful and produced diagnostic images of high resolution. Coarctation was shown in 12 cases. The position and shape of the coarctation were well displayed by the magnetic resonance images. In addit...

A retrospective study using models was performed to evaluate the incremental expansion that occurred during mandibular lip bumper therapy in 44 adolescent patients. The purpose was to determine whether expansion occurs evenly between appointments or whether it attenuates with treatment time. Dental cast measurements were made for arch width and arch length. Treatment duration was broken into ne...

Unilateral posterior arch fractures of the atlas are discussed with two clinical examples and an experimental study of their mechanism. Laboratory fracturing of posterior arches of atlas specimens with a specially adapted universal testing machine produced nonsimultaneous fractures of the two sides in four of six specimens. In three of these specimens, a complete fracture on one side was tempor...

This multi-centre study evaluated the performance of the Osseotite implant in the mandibular arch. Osseotite implants (n = 688) were placed in 172 patients; 43.5% were placed in the anterior mandible and 66.5% in the posterior mandible. Fifteen per cent of the implants were placed in soft bone, 56.9% in normal bone and 28.1% in dense bone. During placement, 49.9% of the implants were identified...
