Clinically-driven need for secondary interventions after endovascular revascularization of tibial arteries in patients with critical limb ischemia

PURPOSE To assess the need for clinically-driven secondary revascularization in critical limb ischemia (CLI) patients subsequent to tibial angioplasty during a 2-year follow-up. METHODS Between 2008 and 2010, a total of 128 consecutive CLI patients (80 men; mean age 76.5±9.8 years) underwent tibial angioplasty in 139 limbs. Rutherford categories, ankle-brachial index measurements, and lower limb oscillometries were prospectively assessed. All patients were followed at 3, 6, 12 months, and annually thereafter. Rates of death, primary and secondary sustained clinical improvement, target lesion (TLR) and target extremity revascularization (TER), as well as major amputation, were analyzed retrospectively. Primary clinical improvement was defined as improvement in Rutherford category to a level of intermittent claudication without unplanned amputation or TLR. RESULTS All-cause mortality was 8.6%, 14.8%, 22.9%, and 29.1% at 3, 6, 12, and 24 months. At the same intervals, rates of primary sustained clinical improvement were 74.5%, 53.0%, 42.7%, and 37.1%; for secondary improvement, the rates were 89.1%, 76.0%, 68.4%, and 65.0%. Clinically-driven TLR rates were 14.6%, 29.1%, 41.6%, 46.2%; the rates for TER were 3.0%, 13.6%, 17.2%, and 27.6% in corresponding intervals, while the rates of major amputation were 1.5%, 5.5%, 10.1%, and 10.1%. CONCLUSION Clinically-driven TLR is frequently required to maintain favorable functional clinical outcomes in CLI patients following tibial angioplasty. Dedicated technologies addressing tibial arterial restenosis warrant further academic scrutiny.

Birth prevalence of isolated congenital limb reduction defects in Texas 1999--2001

Objective. Congenital limb defects are common birth defects occurring in approximately 2-7/10,000 live births. Because congenital limb defects are pervasive throughout all populations, and the conditions profoundly affect quality of life, they represent a significant public health concern. Currently there is a paucity of etiologic information in the literature regarding congenital limb reduction defects which represents a major limitation in developing treatment strategies as well as identifying high risk pregnancies. ^ Additionally, despite the fact that the majority of congenital limb reduction defects are isolated, most previous studies have not separated them from those occurring as part of a known syndrome or with multiple additional congenital anomalies of unknown etiology. It stands to reason that factors responsible for multiple congenital anomalies that happen to include congenital limb reduction defects may be quite different from those factors leading to an isolated congenital limb reduction defect. ^ As a first step toward gaining etiologic understanding, this cross-sectional study was undertaken to determine the birth prevalence and obtain demographic information about non-syndromic (isolated) congenital limb reduction defects that occurred in Texas from 1999-2001. ^ Methods. The study population included all infants/fetuses with isolated congenital limb reduction defects born in Texas during 1999-2001; the comparison population was all infants who were born to mothers who were residents of Texas during the same period of time. The overall birth prevalence of limb reduction defects was determined and adjusted for ethnicity, gender, site of defect (upper limb versus lower limb), county of residence, maternal age and maternal education. ^ Results. In Texas, the overall birth prevalence of isolated CLRDs was 2.1/10,000 live births (1.5 and 0.6/10,000 live births for upper limb and lower limb, respectively). ^ The risk of isolated lower limb CLRDs in Texas was significantly lower in females when gender was examined individually (crude prevalence odds ratio of 0.57, 95% CI of 0.36-0.91) as well as in relation to all other variables used in the analysis (adjusted prevalence odds ratio of 0.58, 95% CI of 0.36-0.93). ^ Harris County (which includes the Houston metropolitan area) had significantly lower risks of all (upper limb and lower limb combined) isolated CLRDs when examined in relation to other counties in Texas, with a crude prevalence odds ratio of 0.4 (95% CI: 0.29-0.72) and an adjusted prevalence odds ratio of 0.50 (95% CI: 0.31-0.80). The risk of isolated upper limb CLRDs was significantly lower in Harris County (crude prevalence odds ratio of 0.45, CI of 0.26-0.76 and adjusted prevalence odds ratio of 0.49, CI of 0.28-0.84). This trend toward decreased risk in Harris County was not observed for isolated lower limb reduction defects (adjusted prevalence odds ratio of 0.50, 95% confidence interval: 0.22-1.12). ^ Conclusions. The birth prevalence of isolated congenital limb reduction defects in Texas is in the lower limits of the range of rates that have been reported by other authors for other states (Alabama, Arkansas, California, Georgia, Hawaii, Iowa, Maryland, Massachusetts, North Carolina, Oklahoma, Utah, Washington) and other countries (Argentina, Australia, Austria, Bolivia, Brazil, Canada, Chile, China, Colombia, Costa Rica, Croatia, Denmark, Ecuador, England, Finland, France, Germany, Hungary, Ireland, Israel, Italy, Lithuania, Mexico, Norway, Paraguay, Peru, Spain, Scotland, Sweden, Switzerland, Uruguay, and Venezuela). In Texas, the birth prevalence of isolated congenital lower limb reduction defects was greater for males than females, while the birth prevalence of isolated congenital upper limb reduction defects was not significantly different between males and females. The reduced rates of limb reduction defects in Harris County warrant further investigation. This study has provided an important first step toward gaining etiologic understanding in the study of isolated congenital limb reduction defects. ^

Deep Venous Thrombosis (DVT) in Lower Extremity Amputation as Cause of Pulmonary Embolism

The authors describe the case of a 43-year-old man with a right-leg knee amputation performed 14 years prior. He presented to hospital with dyspnea. A pulmonary embolism was detected. A Doppler ultrasound test showed deep vein thrombosis (DVT), which affected the stump of the amputated limb. When a pulmonary embolism is detected in a patient with an amputated lower limb, an exploration of the stump should be performed to rule out this uncommon complication.

Biomechanics of the trunk and lower limbs during gait in individuals with and without chronic low back pain

Combining information on kinetics and kinematics of the trunk during gait is important for both clinical and research purposes, since it can help in better understanding the mechanisms behind changes in movement patterns in chronic low back pain patients. Although three-dimensional gait analysis has been used to evaluate chronic low back pain and healthy individuals, the reliability and measurement error of this procedure have not been fully established. The main purpose of this thesis is to gain a better understanding about the differences in the biomechanics of the trunk and lower limbs during gait, in patients and healthy individuals. To achieve these aims, three studies were developed. The first two, adopted a prospective design and focused on the reliability and measurement error of gait analysis. In these test-retest studies, chronic low back pain and healthy individuals were submitted to a gait assessment protocol, with two distinct evaluation moments, separated by one week. Gait data was collected using a 13-camera opto-electronic system and three force platforms. Data analysis included the computation of time-distance parameters, as well as the peak values for lower limb and trunk joint angles/moments. The third study followed a cross sectional design, where gait in chronic low back pain individuals was compared with matched controls. Step-to-step variability of the thoracic, lumbar and hips was calculated, and step-to-step deviations of these segments from their average pattern (residual rotations) were correlated to each other. The reliability studies in this thesis show that three-dimensional gait analysis is a reliable and consistent procedure for both chronic low back pain and healthy individuals. The results suggest varied reliability indices for multi-segment trunk joint angles, joint moments and time-distance parameters during gait, together with an acceptable level of error (particularly regarding sagittal plane). Our findings also show altered stride-to-stride variability of lumbar and thoracic segments and lower trunk joint moments in patients. These kinematic and kinetic results lend support to the notion that chronic low back pain individuals exhibit a protective movement strategy.

El concepto y la práctica de la actividad física y su relación con calidad de vida en los modelos teóricos de la salud

Los estudios acerca del concepto actividad física (AF) son diversos, presentando diferentes concepciones; su relación con calidad de vida suele estar generada dentro del discurso médico, que propende por la ejecución de la Actividad Física desde una mirada netamente biológica. Si bien esta disertación es importante, se debe tener en cuenta que los estudios relacionados con calidad de vida y la AF se basan en la condición de bienestar y percepción frente al estado de salud; dichos estudios no se han realizado desde las condiciones de vida y del contexto social. Si bien es cierto que la mirada médica y lo estudios objetivos son relevantes, ya que arrojan estadísticas que permiten abordar recomendaciones en cuanto a la actividad física, en este documento se elaboró una investigación de tipo cualitativo por medio de la revisión documental del concepto de actividad física, sus prácticas y su relación con calidad de vida, que abordan diferentes autores. Para ello se elige la base de datos PubMed por su énfasis en las publicaciones de salud; se seleccionan artículos publicados del 2004 y 2014, que estudien el concepto de actividad física, sus prácticas y relaciones con calidad de vida, para finalmente hacer un análisis desde los modelos de determinación y determinantes sociales. De esta forma se analiza la posición de los autores con respecto al concepto, sus prácticas y las relaciones que puede llegar a surgir con la calidad de vida. En esta investigación se obtuvo como resultados tendencias biológicas, psicológicas, sociales y culturales, en los cuales los autores dejan clara la posición médica ya que en la mayoría de investigaciones centran sus relaciones en la funcionalidad, y es a través de la visión terapéutica donde buscan el bienestar, la satisfacción de los pacientes que padecen cualquier enfermedad. Además, aparecen categorías emergentes como: cuerpo como medio de publicidad, cibernética que avanza vertiginosamente y el papel del poder en la actividad física que pueden ser contempladas para otros estudios.

Evaluation of deambulation in a protected environment and in the public green in limb amputated subjects treated through a new osteointegration method

The limb amputation is one of the oldest surgical procedures performed and it still represents an event that drastically changes the life of an individual. Despite the technological progress, the difficulties related to the realization and daily use of the socket remain very common. Among the different technologies adopted in the prosthetic field, this project focused on the osseointegration technique. This technique consists in implanting a stem within the medullary canal of the amputated skeletal segment that extends outside the amputation stump with a prosthesis, later connected to the metal extension. The objective of this PhD project is to treat and to evaluate selected patients with osseointegrated prosthetic implants for the treatment of lower limb amputations. Patients are recruited at the Rizzoli Orthopaedic Institute and at the Prosthesis - INAIL center of Vigorso (Budrio) during outpatient visits, while the surgical procedure is performed by the same expert surgeon in the II Orthopaedic and Traumatology Clinic of the Rizzoli Orthopaedic Institute. The project is still ongoing, to date three patients had completed both procedures, but due to various personal problems, just one of them is included in the analysis. This patient increased his percentage of prosthesis use and the level of mobility with an overall improvement of quality of live after the procedure. The osseointegration technique represents a promising alternative method of treatment for amputees who are not satisfied with their socket prosthesis. In the coming years it will continue the collection of clinical, radiographic and kinematic data of subjects undergoing this procedure in order to perform a long-term monitoring of both clinical outcomes and quality of life.

Estudo dos efeitos de temporada de treinamento físico sobre a Performance de uma equipe de handebol feminino sub-21

Handball is a sport that demands endurance associated with fast and powerful actions such as jumps, blocks, sprints and throws. The aim of this study was to evaluate the effects of a 38-week systematic physical training applied to a women's under 21 handball team on upper and lower limb power, 30m sprints speed and endurance. The periodization applied was an adaptation of the Verkhoshansky theory, and aimed at two performance peaks during the season with six data collections. The median and range values for three kg medicine ball throwing was: 2.98m (2.15-3.50); 2.84m (2.43-3.20); 2.90m (2.60-3.38); 3.10 (2.83-3.81); 2.84 (2.55-3.57) and 3.34 (2.93-3.83). Regarding the three-pass running test: 5.60m (4.93-6.58); 5.37m (5.04-6.38); 5.36m (4.93-6.12); 5.65m (4.80-6.78); 5.63m (5.00-6.40) and 5.83m (5.14-6.05). Regarding the 30-m sprint test: 5.8m/s (5.45-6.44); 6,64 m/s (6,24-7,09); 5.65m/s (5.17-5.95); (there was not IV moment for this test); 6.19 m/s (5.57-6.26) and 5.83 (5.14-6.05).Regarding the 30-m sprint endurance test until 10% decrease: 4 sprints (4-6); 5 sprints (4-9); 4,5 sprints (4-16); (there was not IV moment for this test); 6 sprints (4-12) and 5 sprints (4-5). Significant differences (p<0.05) were observed in three kg medicine ball throwing and three-pass running tests at least in one of the performance peak planned, with no significant differences in 30-m sprint speed or endurance tests. The applied physical training was efficient at improving the specific physical fitness in the performance peaks, as well as giving support for better physical training adjustment for the upcoming season.
