OBJECTIVES The elephant trunk technique for aortic dissection is useful for reducing false lumen pressure; however, a folded vascular prosthesis inside the aorta can cause haemolysis. The purpose of this study was to investigate whether an elephant trunk in a small-calibre lumen can cause haemolysis. METHODS Inpatient and outpatient records were retrospectively reviewed. RESULTS Two cases o...

Although oral dental tissue is a vertebrate attribute, trunk dental tissue evolved in several extinct vertebrate lineages but is rare among living species. The question of which processes trigger dental-tissue formation in the trunk remains open, and would shed light on odontogenesis evolution. Extra-oral dental structures (odontodes) in the trunk are associated with underlying dermal bony plat...

BACKGROUND Studies of regional fat distribution in adults with anorexia nervosa (AN) have shown decreased extremity fat at baseline and increased trunk fat with weight recovery, resulting in truncal adiposity. Little is known about fat distribution in adolescents with AN, especially with weight recovery. OBJECTIVE We sought to determine whether regional fat distribution in adolescents with AN...

System-based methods have been applied to assess trunk motor control in people with and without back pain, although the reliability of these methods has yet to be established. Therefore, the goal of this study was to quantify within- and between-day reliability using systems-based methods involving position and force tracking and stabilization tasks. Ten healthy subjects performed six tasks, in...

Can J Surg, Vol. 45, No. 3, June 2002 219 A idiopathic scoliosis (AIS) involves a deformity of the spine that is commonly assessed by physicians. The external trunk deformity is also recognized as a major concern in AIS, especially for the patient. Therefore, many authors advocate that that consideration be given to simultaneous surgical correction of spinal and trunk deformities. During poster...

We investigated the effect of eye-in-head and head-on-trunk direction on heading discrimination. Participants were passively translated in darkness along linear trajectories in the horizontal plane deviating 2° or 5° to the right or left of straight-ahead as defined by the subject's trunk. Participants had to report whether the experienced translation was to the right or left of the trunk strai...

Clinically, wounds on the face tend to heal with less scarring than those on the trunk, but the causes of this difference have not been clarified. Fibroblasts obtained from different parts of the body are known to show different properties. To investigate whether the characteristic properties of facial and trunk wound healing are caused by differences in local fibroblasts, we comparatively anal...

The purpose of this study was to resolve a paradox in the literature on the effects of body orientation on spatial attention. Neuropsychological studies have found that real or simulated trunk rotation relieves contralesional inattention in patients with unilateral neglect, suggesting that trunk orientation affects how attention is allocated to space. However in two previous studies, trunk orie...

BACKGROUND Patients with osteoarthritis of the knee may change their gait in an attempt to reduce loading of the affected knee, thereby reducing pain. Especially changes in lateral trunk motion may be potentially effective, since these will affect the position of the centre of mass relative to the knee, enabling minimization of the load on the knee and thereby knee pain. The aim of the study wa...

BACKGROUND In hemiplegic gait, step length typically differs in magnitude between paretic and nonparetic sides. However, the direction of step-length asymmetry varies across stroke patients. OBJECTIVE The study sought to understand directional variations in step-length asymmetry in terms of asymmetries in forward foot placement relative to the trunk and trunk progression. METHODS A total of...
