Como resultado, foram selecionados e expostos três casos da ocorrência do fenômeno em cirurgias. Foi também realizado um esforço interpretativo dos condicionantes, da dinâmica e dos efeitos da prática de sabote cirúrgico com objetivo de estimular a demanda por serviços médicos e equipamentos médico-hospitalares. Como contribuição, este estudo realiza o delineamento dos elementos que caracterizam a ocorrência deste fenômeno em serviços médicos. Além disso, inaugura uma agenda de futuros estudos que abordam tanto o Estado sendo vitimado pela prática, quanto a ocorrência do fenômeno no setor de serviços.

Abstract Planned obsolescence is a set of actions undertaken by the producer to establish the gradual decay of some attribute of a commodity, artificially stimulating the demand for consumption. The literature on the phenomenon has identified only individuals as victims and objects as forms of expression. This study reports the occurrence of planned obsolescence in public health services. To this end, it consists of an exploratory-interpretative study with a qualitative approach, using the case study of the so-called Prosthetic Mafia. Data were collected by means of bibliographic and documentary research, resulting in three cases that expose the phenomenon occurrence in surgeries. The results were analyzed through an attempt to interpret the conditions, dynamics, and effects of the practice of surgical sabotage to stimulate the demand for medical services and medical-hospital equipment. This study outlines the elements that characterize planned obsolescence occurrence in medical services, inaugurating an agenda of future studies that address both the State being victimized by the practice and the phenomenon in the service sector.

Osteoartrosis de ATM: recuperar la función / TMJ Osteoarthrosis: recover function

Objetivo: evaluar la rehabilitación funcional de la ATM en pacientes con osteoartrosis, con abordaje neuromuscular. La osteoartrosis se caracteriza por la degeneración del cartílago articular y la cortical ósea, que conduce a dolor e inmovilidad. Se incluyó a 8 mujeres entre 20 y 42 años de edad con dolor en la región orofacial, signos de oclusión disfuncional e imágenes compatibles con trastornos degenerativos en ATM. Clínicamente se evaluó el dolor y la oclusión y, mediante tecnología electrónica, se obtuvieron datos objetivos de los movimientos de apertura-cierre y lateralidades, la velocidad de apertura-cierre mandibulares y de los ruidos articulares. Las mediciones fueron realizadas al inicio y al finalizar el tratamiento de estabilización mandibular con una ortosis neuromuscular. Para determinar la significación estadística se utilizaron el Student`s test de comparaciones múltiples y el análisis de varianza, ANOVA, de un factor. Las diferencias entre medias se consideraron significativas con p <0.05. Los resultados demostraron ausencia de dolor en el 100% de los casos al primer mes de tratamiento. Se incrementaron la apertura bucal (6,73 mm promedio), ambas lateralidades (P=0.0023), velocidad en apertura y en cierre (no estadísticamente significativo). Después de estabilizar la mandíbula se redujo la frecuencia de los ruidos. En conclusión, la oclusión dental disfuncional es el principal factor etiológico de la artrosis de la ATM. El establecimiento de una oclusión fisiológica produce la descompresión de la ATM, aumenta el rango de los movimientos mandibulares y disminuye significativamente el dolor (AU)

Objective: to evaluate the functional rehabilitation of the TMJ in patients with osteoarthritis, with a neuromuscular approach. Osteoarthrosis is characterized by degeneration of articular cartilage and bone cortex, which leads to pain and immobility. Eight women between 20 and 42 years of age with pain in the orofacial region, signs of dysfunctional occlusion, and images consistent with degenerative TMJ disorders were included. Clinically, pain and occlusion were evaluated and, using electronic technology, objective data were obtained on the opening-closing movements and lateralities, the opening-closing speed of the jaws and joint noises. Measurements were made before and at the end of the mandibular stabilization treatment with a neuromuscular orthosis. To determine the statistical significance, the Student`s multiple comparisons test and the analysis of variance, ANOVA, of one factor were used. The differences between means were considered significant with p <0.05. The results showed absence of pain pain in 100% of cases in the first month of treatment. Mouth opening (6.73 mm average), both lateralities (P = 0.0023), opening and closing speed (not statistically significant) were increased. After stabilizing the jaw the noise frequency value was reduced. In conclusion, dysfunctional dental occlusion is the main etiologic factor of TMJ osteoarthritis. Establishing a physiological occlusion causes TMJ decompression, increases the range of mandibular movements, and significantly decreases pain (AU)

Orthotic management with a customized humeral brace for Gorham-Stout disease of the humerus: A case report

@#Gorham-Stout disease is characterized by massive osteolysis or "vanishing bone" on radiograph. Due to its rarity, no standard Physical Medicine and Rehabilitation (PM&R) management has been published. With this comes the dilemma of managing another case of vanishing right humerus in a 13 year-old male, right handed student, with normal growth and development. To date, this could be the third documented case in the Philippines, but the first with humeral involvement, and the first to manage using a customized humeral brace. The absence of the right humerus affects the bimanual overhead and tabletop activities of the patient, for which a custom-made humeral orthosis was provided to manage the limited activities. There were improvements in activities such as writing, card turning, stacking, and lifting objects of variable weights, as well as with hand dexterity as evidenced by the standardized hand function tests done prior and post brace fitting. Being a rare bone disease with no standard management and unpredictable course, cases are managed symptomatically. For this case of an absent humerus significantly affecting upper extremity function, orthotic management is one aspect that could be recommended to achieve positive functional outcomes.
