Modular reorganization of gait in chronic but not in artificial knee joint constraint

2021

It is currently unknown if modular reorganization does occur if not the central nervous system, but the musculoskeletal system is affected. The aims of this study were to investigate 1) the effects of an artificial knee joint constraint on the modular organization of gait in healthy subjects; and 2) the differences in modular organization between healthy subjects with an artificial knee joint constraint and people with a similar but chronic knee joint constraint. Eleven healthy subjects and eight people with a chronic knee joint constraint walked overground at 1 m/s. The healthy subjects also walked with a constraint limiting knee joint movement to 20_. The total variance accounted (tVAF) f…

Oval fiber posts do not improve adaptation to oval-shaped canal walls.

2011

Abstract Introduction Oval fiber posts attempt to provide better adaptation to root canals. The hypothesis of this study was that there are no differences in adaptation of oval and circular fiber posts to canal walls. Methods Posts were inserted in 20 canals; 10 were oval, and 10 were circular. The posts were cemented with composite cement. Coronal, middle, and apical sections were observed through a microscope. The space occupied by the post and the maximum distance between it and the canal wall were calculated. The 2 groups were compared with analysis of variance. In all the analyses the level of significance was set at P Results The proportion of space occupied by the post showed no sign…

Funkcionālo un radioloģisko rezultātu salīdzinājums pacientiem pēc pleca locītavas endoprotezēšanas ar Global Icon™ Stemless un Global Unite® anatomi…

Darba aktualitāte: Pleca locītavas endoprotezēšana ir viena no ķirurģiskās ārstēšanas metodēm osteoartrīta slimībai. Mūsdienu tehnoloģiskās iespējas nodrošina endoprotēžu attīstību un daudzveidību. Aizstājot pacienta dabīgo locītavu ar mākslīgo implantu, svarīgi ir izvēlēties viņa stāvoklim, ikdienas aktivitātēm un prasībām atbilstošāko protēzes veidu, lai sasniegtu labāko pēcoperācijas rezultātu. Darba mērķis: Salīdzināt Global Icon anatomiskās bezkājiņas implanta efektivitāti ar Global Unite implanta ar kājiņu efektivitāti, izvērtējot klīniskos un radioloģiskos rezultātus gadu pēc operācijas. Darba uzdevumi: Veikt CMS rezultātu analīzi pirms operācijas un gadu pēc endoprotezēšanas operāci…

Anesthetic management of a patient diagnosed with CADASIL (cerebral arteriopathy, autosomal dominant, with subcortical infarcts and leukoencephalopat…

2011

CADASIL (cerebral arteriopathy, autosomal dominant, with subcortical infarcts and leu-koencephalopathy) is an infrequent inherited disease that could have anesthetic implica-tions. However these have rarely been reported. We present a male patient previously diagnosed with CADASIL, who had suffered an ischemic vascular cerebral accident with a MRI compatible with leukoencephalopathy, and who was dependent for daily activities, and sustained dementia, mood alterations, apathy, and urine incontinence. He had famil-ial antecedents of psychiatric symptoms and ischemic stroke events in several relatives including his father, two brothers and one sister. He was scheduled for arthrodesis of the le…

Accommodative intraocular lenses: current status

2005

Purpose of review The possibility of using a monofocal IOL with accommodative ability allows refractive cataract surgery with a clearly decreased potential of photic phenomena. Three IOLs of different designs and materials have demonstrated accommodative ability, but the degree of accommodative amplitude has been reported to different extents and variabilities. The plate-haptic CrystaLens has a hinged design that might permit forward movement of the optic as a result of pressure changes in the vitreous cavity. The 1CU has modified haptics that bend in the bag as the lens capsule contracts, which are supposed to cause anterior displacement of the lens optic. With the dual-optic one-piece Syn…

CardioPulse: developments in the treatment of aortic aneurysms in 2014

2015

Since the introduction of EndoVascular Aortic Repair (EVAR) for the treatment of abdominal aortic aneurysms (AAA) more than 20 years ago, the technique has evolved rapidly, from tubular grafts for fairly simple abdominal aortic anatomy, to bifurcated, fenestrated, branched, or parallel grafts for complex aortic aneurysms, no longer confined to the infrarenal abdominal aorta.

Early results of a low-profile stent-graft for thoracic endovascular aortic repair

2020

Purpose To assess outcomes of a low-profile thoracic stent-graft in the treatment of thoracic aortic pathologies. Methods A retrospective analysis of all consecutive patients with aortic thoracic pathologies treated with the RelayPro device in two university hospitals between October 2018 and July 2019. Results 23 patients (65% men; mean age 63.4 ± 15 years) were treated. Pathologies included aortic dissections (n = 10), 5 residual type A (22%) and 5 type B (22%), 6 degenerative aortic aneurysms (26%), 4 penetrating aortic ulcers (17%), and aortic erosion, intramural hematoma and aortic rupture (n = 1 and 4% in each case). Two cases (9%) were emergent and two urgent. Proximal landing was a…

Thoracic Endovascular Aortic Repair (TEVAR) for the treatment of aortic diseases: a position statement from the European Association for Cardio-Thora…

2012

Thoracic endovascular aortic repair (TEVAR) is an emerging treatment modality, which has been rapidly embraced by clinicians treating thoracic aortic disease.1–4 Fundamentally, it is a far less invasive approach than open surgery and its availability and relative ease of application has changed and extended management options in thoracic aortic disease, including in those patients deemed unfit or unsuitable for open surgery. In the operating room, this requires considerable perceptual, cognitive and psychomotor demands on the operators. The dramatic expansion of TEVAR activity has necessarily prompted a requirement to systematically consider the indications, appropriateness, limitations and…
