Evaluación crítica de la literatura sobre la toma de decisiones de las metástasis vertebrales / Critical evaluation of the literature on decision-making in spinal metastases

La toma de decisiones en pacientes con metástasis vertebral es de gran complejidad. En ella intervienen distintos factores del paciente, de su enfermedad oncológica y de las opciones de tratamiento. Los esquemas y estrategias de tratamiento se han ido modificando con la propia evolución del conocimiento y tratamiento de la enfermedad oncológica diseminada. En este trabajo se analiza la bibliografía que se ha empleado para la toma de decisiones en las tres últimas décadas, así como la evolución a los esquemas que podríamos considerar contemporáneos.(AU)

[Epidemiology, clinical results and success rate in hip preservation surgery in avascular osteonecrosis of the femoral head]. / Epidemiología, resultados clínicos y tasa de éxito en cirugía preservadora de cadera en la necrosis avascular de cabeza femoral.

INTRODUCTION: Avascular osteonecrosis of the femoral head (ONFH) is a frequent pathology with an insidious and asymptomatic presentation in early stages, so the diagnosis is often made in advanced stages, where the only effective solution is total hip arthroplasty (THA). Diagnosis in early stages will allow the use of therapeutic options that avoid or delay ATC. Our objective is to evaluate the demographic, clinical results and the success rate in our center of patients diagnosed with ONFH and who have been subsidiary of hip preservation surgery. MATERIAL AND METHODS: Unicentric, prospective, uncontrolled clinical study of patients diagnosed with ONFH between January 2012 and September 2017 with a Steinberg IIIA stage. The surgical technique used is decompressive forage, associated with bone allograft and bone marrow aspiration. RESULTS: 26 hips were operated on with our surgical technique. The success rate obtained is 61.54%, since 10 cases have required THA during the study (38.46%). CONCLUSIONS: The therapeutic success in ONFH is directly related to the degree of the disease, which is why early diagnosis is important. The decompressive forage with bone allograft that associates bone marrow aspiration is an option to be taken into account, since in early stages it shows a high success rate.

INTRODUCCIÓN: La necrosis avascular de cabeza femoral (NACF) es una patología frecuente que en sus inicios es asintomática y se manifiesta de forma insidiosa, por lo que a menudo el diagnóstico se realiza en estadios avanzados, donde la única solución eficaz es la artroplastía total de cadera (ATC). El diagnóstico en fases precoces permitirá utilizar opciones terapéuticas que eviten o retrasen la ATC. Nuestro objetivo es valorar los resultados demográficos, clínicos y la tasa de éxito en nuestro centro de pacientes con diagnóstico de NACF y que han sido subsidiarios de cirugía de preservación de cadera. MATERIAL Y MÉTODOS: Estudio clínico unicéntrico, prospectivo, no controlado de pacientes con diagnóstico de NACF entre Enero de 2012 y Septiembre de 2017 con un estadio Steinberg IIIA. La técnica quirúrgica utilizada es el forage descompresivo, asociado a relleno con aloinjerto y aspirado de médula ósea. RESULTADOS: Se intervinieron 26 caderas con nuestra técnica quirúrgica. La tasa de éxito obtenida es de 61.54%, ya que 10 casos han precisado ATC durante el estudio (38.46%). CONCLUSIÓN: El éxito terapéutico en la NACF está directamente relacionado con el grado de la enfermedad, por lo que es importante el diagnóstico precoz. El forage descompresivo con relleno de aloinjerto que asocia aspirado de médula ósea es una opción a tener en cuenta, ya que en estadios iniciales muestra una elevada tasa de éxito.

[Unusual evolution of reactive arthritis after endovesical immunotherapy with BCG].

Intravesical instillation of BCG (Bacille Calmette-Guerin) is a therapy prepared with weakened strains of Mycobacterium bovis and is an effective complementary treatment for high-risk (non-musculoinfiltrating or non-invasive) bladder cancer. Although its safety for clinical use is high, endovesical immunotherapy is not without complications. Arthralgia and arthritis are infrequent, but potentially severe, complications, the early diagnosis of which can allow adequate medical treatment and avoid chronification of the pathology. This case shows the therapeutic management of hip osteoarthritis in a 59-year-old woman, a rare and serious complication, secondary to a rare pathology such as reactive arthritis due to BCG instillation.

Resultados medidos con captura de movimiento en las fracturas de húmero proximal tratadas mediante osteosíntesis con placa bloqueada / Results measured by means of a motion capture system in proximal humerus fractures treated by osteosynthesis with locking plate

Objetivo: Evaluar los resultados de las fracturas de húmero proximal tratadas mediante osteosíntesis con placa empleando captura de movimiento y escalas funcionales. Material y método: Estudio retrospectivo de 47 pacientes mayores de 65 años, tratados mediante osteosíntesis con placa bloqueada en el mismo centro, desde enero de 2010 a diciembre de 2014. Tras un seguimiento mínimo de 2 años, se realizó una evaluación de los resultados obtenidos mediante 2 escalas funcionales (Constant-Murley y Quick DASH) y una escala de calidad de vida (EQ-5D). Para analizar el balance articular de forma objetiva se empleó un sistema de análisis cinemático con cámaras y sin marcadores. Resultados: La edad media fue 74,85 años. Los resultados funcionales expresados mediante la puntuación media fueron: Constant-Murley, 70,06 puntos; Quick DASH, 35,74 puntos; y EQ-5D, 6,79 puntos. Los arcos de movilidad medios fueron: flexión, 111,49°; extensión: 24,13°; abducción: 109,40°; aducción: 15,13°; rotación externa: 38,96° y rotación interna: 49,28°. Se encontró correlación estadística entre las 2 escalas funcionales y de ambas con la EQ-5D. También se advirtió correlación estadística entre los movimientos estudiados con las escalas funcionales (excepto rotación externa) y con la escala de calidad de vida (excepto flexión y rotación externa). Conclusión: La osteosíntesis con placa bloqueada en las fracturas de húmero proximal del anciano obtiene unos buenos resultados funcionales y de calidad de vida. El uso de sistemas de captura de movimiento permite una medición más objetiva de estos resultados y puede ser una herramienta útil en la valoración funcional de esta patología

Objective: To evaluate the results after locking plate internal fixation of proximal humerus fractures by means of a motion capture system, and functional scales. Material and method: Retrospective study of a cohort of 47 elderly patients undergoing surgery from January 2010 to December 2014. After a minimum follow-up of two years, two functional scales (Constant-Murley and Quick DASH), and a quality of life scale (EQ-5D) were used for clinical evaluation. For objective evaluation of the range of motion a kinematic marker-free analysis with cameras was performed. Results: The average age was 74.85 years. Average functional scores were: Constant-Murley 70.06 points, Quick DASH 35.74 points and EQ-5D 6.79 points. The average range of motion was: flexion, 111.49°; extension: 24.13°; abduction: 109.40°; adduction: 15.13°; external rotation: 38.96°, and internal rotation: 49.28°. Correlation was found between the two functional scales, between them and the EQ-5D, and between range of motion and functional scales (except for external rotation) as well as between range of motion and EQ-5D (except for flexion and external rotation). Conclusion: Locking plate osteosynthesis in proximal humerus fragility fractures achieved good functional and quality of life scores. Motion capture systems can be a useful tool for the functional assessment of shoulder pathology allowing an objective evaluation of range of motion

Application of International Caries Detection and Assessment System (ICDAS) and Caries Management by Risk Assessment (CAMBRA) systems in child cancer patients: a clinical case report.

BACKGROUND: Leukaemia represents 30-40% of all paediatric malignant tumours and is the main cause of death in patients aged <15 years. One of the main complications in these patients is infection, which may often occur in the oral cavity. Chemotherapy-related oral health problems may be reduced by oral healthcare strategies based on the International Caries Detection and Assessment System (ICDAS) and Caries Management by Risk Assessment (CABRA). CASE REPORT: A case is reported of a 14-year-old girl treated for leukaemia who presented with established dental caries lesions which were classified and treated according to ICDAS and CABRA protocols. After three, no new caries was observed. FOLLOW-UP AND CONCLUSION: ICDAS and CAMBRA provide useful and effective guidance for the avoidance of dental and systemic problems. Their introduction into standard practice could reduce the legal difficulties derived from dental treatment in these patients.

Treatment of congenital pseudarthrosis of the tibia with vascularized fibular periosteal transplant.

The vascularized fibular periosteal flap has been recently described and showed solid angio and osteogenic features. We report the use of a free vascularized fibular periosteal transplant in the treatment of a El-Rosasy-Paley Type III congenital pseudarthrosis of the tibia in a 7-year-old boy, with a prior unsuccessful surgery at the age of three. The contralateral fibular periosteum was used to replace two-thirds of the hamartomatous tibial periosteum. We did not proceed to debriding the focus of the pseudarthrosis nor addressed the tibial recurvatum or revised the previous tibial rod. Consolidation was achieved radiologically at 3 months, allowing for the tibial rod to be removed. One year postoperatively, the patient ambulated without the use of a protective orthesis and resumed his sports practice. This novel pathogenesis-based technique showed promising results and a prompt healing of such a difficult orthopedic condition.

Detección de disfonías en la escuela: la función del maestro de audición y lenguaje en educación / Detection the disphonics in the school: the teacher's of audition and language function in education

Nuestro interés por las disfonías ha sido una constante en nuestro día a día como maestros de audición y lenguaje. Esta cuestión se torna difícil cuando trabajamos con niños de edad inferior a 7 años, ya que el diagnóstico se complica notablemente, pero esto lo dejamos para los médicos especialistas. Nuestro ámbito de trabajo nos recomienda una detección precoz, que con estos alumnos se hace muy difícil debido a su temprana edad. Este estudio aborda la problemática de la detección de disfonías en edades de 4 a 7 años principalmente, con la ayuda del procesamiento de la voz y el análisis de los formantes de determinados sonidos. Se trataría de una tecnología imprecisa, pero suficiente y poco costosa para realizar barridos de clases completas de alumnos de educación infantil y primeros ciclos de primaria, permitiéndonos realizar derivaciones a los servicios de otorrinolaringología (ORL) con cierta garantía

Our interest for the dysphonia has been day by day a constant in our as audition teachers and language. This question is more difficult when we work with children of inferior age to 7 years, since the diagnosis gets complicated notably, but this leaves it for the specialist doctors. Our work environment recommends us a precocious detection that becomes very difficult with these students due to its early age. This study approaches the problem of the dysphonia detection in ages from 4 to 7 years mainly, with the help of the prosecution of the voice and the analysis of the formants of certain sounds. It would be an imprecise, but enough and not very expensive technology to carry out sweepings of students of infantile education complete classes and first cycles of primary, allowing us to carry out derivations to the services of ORL with certain guarantee

[Propranolol protects the myocardium and prevents arterial hypotension in an experimental organ donation model]. / El propranolol protege el miocardio y previene la hipotensión arterial en un modelo experimental de donante de órganos.

OBJECTIVE: To analyze the role that sympathetic nervous system hyperactivity immediately following brain death plays in the cardiovascular dysfunction of an organ donor. MATERIAL AND METHOD: Fifteen New Zealand white rabbits were placed in three groups: a control group, a brain-death group without propranolol and a brain-death group with propranolol. Brain death was caused by severe intracranial hypertension; in the third group propranolol was first perfused intravenously. We recorded hemodynamic (heart rate, number of extrasystoles, central venous pressure, systemic and pulmonary arterial pressure), biochemical (adrenaline, noradrenaline, dopamine and troponin T) and histologic data. RESULTS: Catecholamine levels rose significantly in both experimental groups after brain death, which coincided with clinical signs of sympathetic hyperactivity in the group not receiving propranolol but not in the group receiving the beta-blocker. The myocardium of animals not receiving the beta-blocker showed myocytolysis, edema, subendocardial bleeding and leukocyte infiltration. Such changes were practically absent in the animals that received beta-blockers. In the beta-blocker group, serum troponin, and index of myocytolysis, rose significantly less than in the non-premedicated group. Blood pressure in all the brain-dead animals was significantly lower than in the control group, but was more severe in animals that had not received propranolol. CONCLUSIONS: Sympathetic nervous system hyperactivity after brain death affects the histology and functioning of the myocardium in this experimental organ donor model. Pretreatment with propranolol prevents damage.

[Diagnosis of brain death using trancranial Doppler ultrasonography in an experimental model of organ donation for transplantation]. / Diagnóstico de la muerte encefálica mediante ultrasonografía Doppler transcraneal en un modelo experimental de donante de órganos para trasplante.

OBJECTIVE: To create an experimental organ donor model and validate it by ultrasound evaluation of intracranial blood flow velocity. MATERIAL AND METHOD: Ten white New Zealand rabbits were assigned to either a control group or an experimental group. Brain death was induced in the experimental group by way of severe cranial hypertension. A diagnosis of brain death was based on physical examination and velocity of intracranial blood flow determined by transcranial doppler ultrasonography. Physical and ultrasound examinations were performed on all animals at baseline and at the time of the experiment. RESULTS: Physical examination and intracranial blood flow velocity were normal in the control group animals at baseline and during the study. The findings were also normal for the experimental group animals at baseline. After provocation of intracranial hypertension, we observed signs of brain death (absence of response to pain stimulus in one cranial par absence of brainstem reflexes, and apnea) in the experimental animals, and the velocity of flow in arteries at the base of the skull acquired the waveform known as sharp systolic peaks, which are characteristic of cerebral circulation failure. CONCLUSIONS: The results of physical examination and ultrasonography in this study provide adequate validation of this experimental model of brain death and demonstrate that transcranial doppler ultrasonography is useful for diagnosing brain death in the rabbit.

Diagnóstico de la muerte encefálica mediante ultrasonografía Doppler transcraneal en un modelo experimental de donante de órganos para trasplante / Diagnosis of brain death by transcranial doppler ultrasonography in an experimental organ donor model

OBJETIVO: Crear un modelo experimental de donante de órganos para trasplante y validarlo mediante el estudio ultrasonográfico de la velocidad del flujo sanguíneo intracraneal. MATERIAL Y MÉTODO: Se emplearon 10 conejos blancos de Nueva Zelanda divididos en un grupo control y un grupo experimental. En el segundo se provocó la muerte encefálica (ME) por un mecanismo de hipertensión intracraneal (HTIC) severa. El diagnóstico de la ME se basó en la exploración clínica y en el estudio de la velocidad del flujo sanguíneo intracraneal mediante ultrasonografía Doppler transcraneal. Ambas exploraciones fueron realizadas en todos los animales en situación basal y experimental. RESULTADOS: La exploración clínica y la velocidad del flujo sanguíneo intracraneal fueron normales en los animales del grupo control tanto en situación basal como experimental. En el grupo experimental también se obtuvieron resultados normales en ambos casos en situación basal, pero tras provocar HTIC aparecieron los signos clínicos diagnósticos de la ME (ausencia de respuesta a estímulos dolorosos en el territorio de un par craneal, ausencia de reflejos troncoencefálicos y apnea) y la velocidad del flujo sanguíneo en las arterias de la base del cráneo adoptó un patrón denominado "espigas sistólicas", que es característico de la parada circulatoria cerebral. CONCLUSIONES: Los resultados obtenidos en la exploración clínica y ultrasonográfica en nuestro estudio suponen la validación adecuada de este modelo experimental de ME y demuestran que la ultrasonografía Doppler transcraneal es útil en el diagnóstico de la ME en el conejo.

El propranolol protege el miocardio y previene la hipotensión arterial en un modelo experimental de donante de órganos / Propranolol protects the myocardium and prevents arterial hypotension in an experimental organ donor model

OBJETIVO: Analizar el papel que desempeña la hiperactividad del sistema nervioso simpático (SNS) que tiene lugar inmediatamente después de producirse la muerte encefálica (ME) en la disfunción cardiovascular del donante de órganos. MATERIAL Y MÉTODO: Quince conejos blancos de Nueva Zelanda han sido divididos en tres grupos: grupo control, grupo de ME sin propranol y grupo de ME con propranolol. La ME se provocó por hipertensión intracraneal severa; en el tercer grupo, antes de hacerlo se administró propranolol IV. Se recogieron datos hemodinámicos (frecuencia cardiaca, número de extrasístoles, presión venosa central, presión arterial sistémica y pulmonar), bioquímicos (adrenalina, noradrenalina, dopamina y troponina T) e histológicos. RESULTADOS: En ambos grupos experimentales se elevaron significativamente las catecolaminas tras la ME. Este hecho coincidió con signos clínicos de hiperactividad simpática en el grupo sin propranolol, pero no en el betabloqueado. El miocardio de los animales no betabloqueados mostró miocitolisis, edema, hemorragia subendocárdica e infiltrado leucocitario, alteraciones que estuvieron prácticamente ausentes en los animales betabloqueados. En el grupo betabloqueado la troponina sérica, índice de miocitolisis, se elevó significativamente menos que en el no premedicado. En todos los animales en ME la presión arterial descendió significativamente respecto al grupo control, pero la hipotensión fue más severa en los animales que no recibieron propranolol. CONCLUSIONES: La hiperactividad de SNS posterior a la ME afecta histológica y funcionalmente al miocardio de este modelo experimental de donante de órganos. El pretratamiento con propranolol previene dicho daño. (AU)
