Delayed chronic intracranial subdural hematoma complicating resection of a tanycytic thoracic ependymoma
2015
Background To demonstrate that the diagnosis of an intracranial subdural hematoma should be considered for patients presenting with acute or delayed symptoms of intracranial pathology following resection of a spinal tumor. Case description We present a case of a 57-year-old woman found to have a chronic subdural hematoma 1 month following resection of a thoracic extramedullary ependymoma. Evacuation of the hematoma through a burr hole relieved the presenting symptoms and signs. Resolution of the hematoma was confirmed with a computed tomography (CT) scan. Conclusion Headache and other symptoms not referable to spinal pathology should be regarded as a warning sign of an intracranial subdural…
Pie zambo sindrómico más allá de la artrogriposis y el mielomeningocele: tratamiento ortopédico con el método de Ponseti
2021
Resumen: Introducción: El pie zambo supone una de las malformaciones congénitas del pie más frecuentes. Generalmente la etiología es idiopática. Sin embargo, pueden presentar una causa sindrómica y asociarse con afecciones musculoesqueléticas, neurológicas o del tejido conjuntivo, recibiendo en estos casos, la denominación de pie zambo sindrómico.El tratamiento de elección del pie zambo idiopático es el método Ponseti, basado en la manipulación y yesos seriados. También se ha demostrado su utilidad en pie zambo asociado con artrogriposis y mielomeningocele, pero existen pocas publicaciones sobre la eficacia en el pie zambo sindrómico. Material y métodos: Estudio retrospectivo en seis pacien…
Virtual simulation of an osseointegrated trans-humeral prosthesis: A falling scenario
2018
Abstract Introduction Traditional prosthetic solutions expose the amputee to numerous problems that limit his ability to safely perform the normal activities of daily life. In order to eliminate the problems related to the use of the traditional prosthesis with socket, a new technique was developed for fixing the prosthesis to the amputees based on the principle of osseointegration. The aim of this paper is to study and analyze the stress distribution on the interface between a trans-humeral osseointegrated prosthetic implant and the residual bone, identifying the most stressed areas and thus foreseeing possible failure phenomena of the entire prosthetic system and, after, to compare the st…
Participation and performance trends in 'Ultraman Hawaii' from 1983 to 2012
2013
Abstract Background Participation and performance trends have been investigated in a single stage Ironman triathlon such as the ‘Ironman Hawaii,’ but not for a multi-stage ultra-triathlon such as the ‘Ultraman Hawaii’ covering a total distance of 515 km. The aims of this study were to analyze (1) changes in participation and performance, (2) sex-related differences in overall and split time performances, and (3) the age of peak performance in Ultraman Hawaii. Methods Age and race times including split times for 98 women and 570 men who successfully finished Ultraman Hawaii (day 1 with 10-km swimming and 145-km cycling, day 2 with 276-km cycling, and day 3 with 84-km running) between 1983 an…
Sex difference in Double Iron ultra-triathlon performance
2013
Abstract Background The present study examined the sex difference in swimming (7.8 km), cycling (360 km), running (84 km), and overall race times for Double Iron ultra-triathletes. Methods Sex differences in split times and overall race times of 1,591 men and 155 women finishing a Double Iron ultra-triathlon between 1985 and 2012 were analyzed. Results The annual number of finishes increased linearly for women and exponentially for men. Men achieved race times of 1,716 ± 243 min compared to 1,834 ± 261 min for women and were 118 ± 18 min (6.9%) faster (p < 0.01). Men finished swimming within 156 ± 63 min compared to women with 163 ± 31 min and were 8 ± 32 min (5.1 ± 5.0%) faster (p < …
Sex difference in race performance and age of peak performance in the Ironman Triathlon World Championship from 1983 to 2012
2012
Abstract Background The fastest Ironman race times in ‘Ironman Hawaii’ were achieved in very recent years. This study investigated the change in sex difference in both race performance and the age of peak performance across years in the top ten athletes for split disciplines and overall race time in the ‘Ironman Hawaii’ between 1983 and 2012. Methods Changes in split times, overall race times, and age of athletes across years for the top ten overall and the fastest swimmers, cyclists, and runners were investigated using regression analyses and analyses of variance. Results Between 1983 and 2012, the overall top ten men and women finishers improved their swimming (only men), cycling, running…
Performance and Age of the Fastest Female and Male 100-km Ultramarathoners Worldwide From 1960 to 2012
2015
International audience; The purpose of this cross-sectional study was to investigate the change in 100-km running performance and in the age of peak performance for 100-km ultramarathoners. Age and running speed of the annual fastest women and men in all 100-km ultramarathons held worldwide between 1960 and 2012 were analyzed in 148,017 finishes with 18,998 women and 129,019 men using single, multivariate, and nonlinear regressions. Running speed of the annual fastest men increased from 8.67 to 15.65 km.h(-1) and from 8.06 to 13.22 km.h(-1) for the annual fastest women. For the annual 10 fastest men, running speed increased from 10.23 ± 1.22 to 15.05 ± 0.29 km.h(-1) (p < 0.0001) and for the…
A study of reproducibility of kinesiology tape applications: review, reliability and validity
2017
Abstract Background Literature addressing the mechanical properties of kinesiology tape is quite scarce. There are no studies which focus on the mechanical characteristics of kinesiology tape, its mechanical properties, nor its adherence following the ISO international standard test methods for tape elongation. Methods This study quantified the mechanical characteristics of 380 samples of kinesiology tape from 19 different brands and in 4 different colors using a dynamometer. Mechanical testing was controlled by UNE EN ISO 13934-1. Results Significant differences were found between tape brands in terms of grammage, maximum force tenacity, work, pre-elongation and percentage elongation (P < …
The Thin bilateral and bipedicled DIEAP flap for axillary reconstruction in hidradenitis suppurativa
2019
Reconstruction after resection of advanced stage hidradenitis suppurativa is currently performed with pedicled perforator flaps, that allow functional reconstruction and preservation of shoulder function. Skin availability is limited by the possibility of closing the donor site primarily. Bilateral cases need to be treated in two stages, since the operation is carried out in the lateral decubitus. In this manuscript the application of bilateral and bipedicled DIEAP flaps to bilateral and extensive cases is presented.Between October 2008 and October 2018, 39 patients were treated for axillary hidradenitis suppurativa. Of these, 11 patients had bilateral reconstruction with bilateral DIEAP fl…
Assessment of Gait after Treatment of Tibial Nonunion with the Ilizarov Method
2021
Background: Tibial nonunion is a common bone union disorder leading to abnormal gait, and thus reducing quality of life in the social dimension. Research question: The aim of our work was to comprehensively assess gait parameters of patients who had undergone Ilizarov treatment for tibial nonunion compared to a control group of healthy individuals. Methods: This study evaluated patients treated for aseptic tibial nonunion with the Ilizarov method. 24 patients with a mean age of 55.0 years were included in the study. The control group consisted of 32 healthy volunteers with no significant medical history who were selected to match the gender and age of patients in the study group so that the…
