    The present study was undertaken to examine the positions of Spanish health professionals on a variety of bioethical issues and to determine the relationships between these positions and the professionals’ religious beliefs and political views. The study sample consisted of 50 individuals randomly selected from a database of Spanish health professionals who had received solid training in bioethics. A structured questionnaire was designed that contained six closed questions on positions on biomedical advances and science and biotechnology (eugenics, use of nonimplanted embryos for experimental purposes, human cloning, and the idea that science should have limits) and the respondents’ sociopolitical and religious views, and assessment scales were developed for the responses. The distribution of the responses was subjected to statistical analysis using analysis of variance (ANOVA). For the items with responses scored on a Likert scale, the positions taken were moderately adverse, and the vast majority of respondents believed that there should be limits to science. Religious convictions had greater influence on the responses than political orientation. There was evidence that liberal beliefs corresponded with what the authors consider to be more progressive ideas about the bioethics issues addressed in the study. The important questions of bioethics require an interdisciplinary approach and a combination of state and private-sector action to strengthen the links between religion and science, keep general knowledge up to date, and properly train biotechnology professionals.Se realizó el presente estudio para examinar las posiciones de profesionales de la salud española sobre una variedad de temas bioéticos y determinar las relaciones entre estas posiciones y las creencias religiosas y puntos de vista políticos de los profesionales. La muestra del estudio consistió de 50 individuos seleccionados al azar de una base de datos de profesionales de la salud en España que habían recibido formación sólida en bioética. Se diseñó un cuestionario estructurado con seis preguntas cerradas sobre posiciones acerca de avances biomédicos, de ciencia y biotecnología (eugenesia, uso de embriones no implantados para propósitos experimentales, clonación humana y la idea de que la ciencia debería tener límites), y los puntos de vista sociopolíticos y religiosos de los respondientes, y se desarrollaron escalas de evaluación para las respuestas. Se sometió la distribución de las respuestas a análisis estadístico usando análisis de varianza (ANOVA). Para los elementos con respuestas valuadas con una escala Likert, las posiciones tomadas fueron moderadamente adversas y la inmensa mayoría de los respondientes creían que debería haber límites para la ciencia. Las convicciones religiosas tuvieron mayor influencia en las respuestas que la orientación política. Hubo evidencia de que las creencias liberales se correspondieron con las que el autor consideraba ideas más progresistas sobre temas de bioética abordados en el estudio. Las preguntas importantes de bioética requieren una aproximación interdisciplinaria y una combinación de acción estatal y del sector privado para fortalecer los vínculos entre religión y ciencia, mantener el conocimiento general actualizado y formar apropiadamente a los profesionales de la biotecnología.O presente estudo foi realizado para examinar a posição de profissionais de saúde da Espanha sobre uma variedade de temas bioéticos e determinar a correlação entre estas posições e crenças religiosas dos profissionais e pontos de vista políticos. A amostra estudada consistiu de 50 indivíduos selecionados aleatoriamente da base de dados de profissionais de saúde da Espanha que receberam sólido treinamento em bioética. Um questionário estruturado foi definido para conter seis questões fechadas sobre posições a cerca de avanços biomédicos, ciência e biotecnologia (eugenia, utilização de embriões não implantados para projetos experimentais, clonagem humana e a ideia de que a ciência deveria ter limites) e os pontos de vista sociopolítico e religioso dos respondentes, e escalas de avaliação foram desenvolvidas para as respostas. A distribuição das respostas foi objeto de análises estatísticas utilizando a análise de variância (ANOVA). Para os itens com respostas computadas pela escala de Likert, desde de ‘concorda fortemente’ a ‘discorda fortemente’, as posições tomadas foram moderadamente adversas, e a vasta maioria dos respondentes acreditaram que deveria haver limites para a ciência. Convicções religiosas tiveram maior influência nas respostas do que aquelas de orientação política. Houve evidência de que crenças liberais corresponderam com o que os autores consideram ser ideias mais progressistas sobre temas bioéticos direcionados pelo estudo. As importantes questões de bioética requerem uma abordagem interdisciplinar e uma ação combinada dos setores público (estatal) e privado para revigorar os elos entre religião e ciência, manter um conhecimento geral atualizado, e treinar adequadamente profissionais em biotecnologia

    [Abstract] A 6-month-old Caucasian baby is described with a postaxial polydactyly of the letf foot. Radiographic examination revealed the accessory digit was composed of soft tissue, some with a tiny osseous element, originated from around the metatarsophalangeal joint, defined by floating type (FT). The parents had consistent difficulty putting shoes. We encountered an exceedingly rare presentation of FT, to our inspection, had neither been previously related in published studies. To the best of our knowledge, this represents the unusual case of congenital deformity lesion on the left foot to be reported in the medical literature

    El diagnóstico de una hipertrofia de la tróclea o tuberosidad peroneal del calcáneo se asocia a una tenosinovitis estenosante del tendón del músculo Peroneo Largo o Corto. Hay autores que plantearon que la hipertrofia de la tróclea del calcáneo no provocaba dolor por si misma sino que se produce una exacerbación del dolor cuando el paciente utiliza un zapato que comprime el pie afecto, lo cual produce una irritación en la piel por la compresión a la que ésta estaba sometida, acompañada muchas veces por una afectación sensitiva superficial por atrapamiento del nervio Dorso Cutáneo Lateral.The diagnosis of troclear hypertrophy or fibular tuberosity of calcaneus is associated to stenotic tenosinovitis of long or short the peroneal tendon. There are authors states that troclear hypertrophy of calcaneus did not cause pain by itself but the pain increase when the patient uses a tight shoe that compresses the area affected, this compression produces skin irritation under the area affected accompanied often a sensorial affectation at level of the superficial nerve due to entrapment of dorso cutaneous lateral nerve

    Structural interaction between bone and implants due to arthroplasty of the first metatarsophalangeal joint

    Background: Currently, the metatarsophalangeal joint replacement through a restorative arthroplasty, where implants are used, is a viable invasive surgical medical procedure in the treatment of severe cases of osteoarthritis in this joint, better known as hallux rigidus. However, few things are known about the postoperative complications that implants can cause on the joint, like Swanson and Tornier implants.Research in this field can provide a valuable information that would help the specialist surgeon in the decision-making during the selection of the more suitable joint implant in each patient, as well as the redesign of the devices, to make them more efficient, durable and biocompatible with the human body. Methods: The aim of this work is to perform a structural biomechanical analysis of a restorative arthroplasty of the first metatarsophalangeal joint, and to analyze the interaction between bone and medical grade silicone implants. For that, a simulation of a foot with Swanson and Tornier joint implants were performed to evaluate the stress/strain distribution during a critical stage (toe-off). Results and conclusions: Principal stresses obtained for the first metatarsal with both implants suggest that failure is induced in this bone because, values exceed (up to 136.84% for Swanson model) the tensile strength reported for phalange trabecular bone, which may be related to osteolysis. Stress and strain values obtained in this work suggest that arthroplasty surgery with Swanson implant is more likely to cause postoperative complications versus Tornier implant

    Effectiveness of calcaneal osteotomy in surgical treatment of foot conditions: A Prisma statement guidelines compliant systematic review

    Get PDF
    [Abstract] Calcaneal osteotomy is a commonly established method used to correct various foot malalignment surgery problems that produce varus and valgus hindfoot abnormality as well as Haglund's deformity, cavovarus foot reconstruction, flatfoot deformity, plantar fasciitis, posterior tibial tendon insufficiency and planovalgus foot. After decades, several procedures in orthopaedic foot surgery have been suggested for reducing the risk of wound and neurovascular complications. The goal of this Prisma statement guidelines compliant systematic review was to establish the effectiveness and safety of calcaneal osteotomy in foot surgery. We have performed a novel systematic review of the current published literature in order to evaluate the scientific evidence now available on this association, assigning predefined exclusion and inclusion criteria. Eight investigations were selected which had 191 cases. The adult flatfoot, tibialis posterior reconstruction and cavovarus foot deformity were treated with different procedures of calcaneal osteotomy techniques. The adequate level of effectiveness of calcaneal osteotomy is associated with the kind and location of the incision, with or without screw application, in each specific foot condition. There is a limited number of scientific investigations of the effectiveness and safety of the different kinds of calcaneal osteotomy in foot surgery, and there is the need to enhance outcome knowledge on this foot surgery technique

    4 p.Inadequate footwear, painful and hyperkeratotic lesions (HL) are an extremely common problems amongst older people. Such problems increase the risk of falls, hamper mobility, reduction of quality of life, dignity, and ability to remain independent. The etiology of painful and feet conditions is poorly understood. To discover footwear preferences of older people, pain tolerance may favor presence of HL for the use of inadequate footwear in old age. A sample of 100 participants with a mean age of 74.90 ± 7.01 years attended an outpatient clinic where self-reported demographic data, frequency with which they checked their feet were recorded and measurements were taken of foot sensitivity. Additionally, all participants’ shoes were allocated into optimal, adequate, and dangerous categories based on design, structural and safety features, and materials. Only 12% of the sample population checked their feet every day, 37% revealed symptoms of neuropathy, 14% used optimal shoes, and 61% presented HL. In a bivariate analysis, no significant differences were observed. HL are associated with inadequate footwear, loss of sensitivity, and low frequency of foot health checks.S

    Geometry of the Proximal Phalanx of Hallux and First Metatarsal Bone to Predict Hallux Abducto Valgus: A Radiological Study

    [Abstract] Background Hallux abducto valgus (HAV) is one of the most common forefoot deformities in adulthood with a variable prevalence but has been reported as high as 48%. The study proposed that HAV development involves a skeletal parameter of the first metatarsal bone and proximal phalanx hallux (PPH) to determine if the length measurements of the metatarsal and PPH can be used to infer adult HAV. Methods All consecutive patients over 21 years of age with HAV by roentgenographic evaluation were included in a cross-sectional study. The control group included patients without HAV. The study included 160 individuals. We identified and assessed the following radiographic measurements to evaluate HAV: the distances from the medial (LDM), central (LDC), and lateral (LDL) aspects of the base to the corresponding regions of the head of the PPH. The difference between the medial and lateral aspect of PPH was also calculated. Results The reliability of the variables measured in 40 radiographic films show perfect reliability ranging from 0.941 to 1 with a small error ranging from 0.762 to 0. Also, there were no systematic errors between the two measurements for any variable (P > 0.05). The LDM PPH showed the highest reliability and lowest error. Conclusion It is more suitable to measure the LDM PPH instead of the LDC PPH when calculating the hallux valgus angle based on our reliability results. When the differences of the medial and lateral PPH are greater, the risk for developing HAV increases
