Objetivo: Comparar la tasa de mortalidad, el estado funcional, mental y las complicaciones en pacientes, mayores de 60 años, con fractura de cadera tratados mediante cirugía o de modo conservador. Material y método: Se compararon dos grupos de pacientes, uno con tratamiento conservador (N=111) y otro con pacientes operados (N=90). Los registros se tomaron al mes, tres, seis y 12 meses de la fractura y la mortalidad se estudió mensualmente. Resultados: En el estado funcional observamos un deterioro funcional grave durante el primer mes en ambos grupos, con mejor recuperación en los pacientes intervenidos. El estado mental siguió curvas paralelas, con mejores resultados en el grupo de los operados. Las complicaciones fueron constantes en ambos grupos desde la fractura, siendo mayor en los pacientes que no se operaron. La mortalidad en el grupo con tratamiento conservador fue máxima en los tres primeros meses. Conclusión: Las complicaciones y tasas de mortalidad son superiores en aquellos pacientes que no se operan (AU)


Objective: To compare mortality in patients older than 60 years after hip fracture depending on if they are operated or treated without surgery. To study differences in functional and general state and to analyse complications. Material and method: We made two group, one group was formed with 111 no operated patients (study group) and the other one with 90 patients operated (control group). Dates were collected at 1, 3, 6 and 12 month after fracture. We analyzed each month the mortality of our patients. Results: There was a great functional decrement in both groups, but with a better recover in operated patients. We found a similar evolution in both groups for mental state, but with better results in operated. Number of complications was constant in both groups since fracture time, but there were more complications in study group. Mortality was maxim in study group at 3 months, while in control group it was constant during the study period. Conclusion: Complications and mortality after hip fracture is greater in no operated patients (AU)

Objetivo: Identificar los factores de riesgo asociados al aumento de mortalidad en pacientes de edad avanzada que no son intervenidos tras padecer una fractura de cadera. Material y método: Estudio prospectivo durante un año, de 111 pacientes que sufrieron una fractura de cadera y no fueron intervenidos. Los criterios de inclusión fueron tener más de 60 años, no padecer una fractura patológica y no fallecer durante su ingreso. Todos fueron seguidos durante un año o hasta su defunción. Los factores de riesgo analizados en el estudio fueron: edad, sexo, estado general de salud, deterioro mental, estado funcional previo a la fractura y tipo de fractura. Resultados: El principal factor de riesgo fue el estado general deteriorado antes de la fractura. La edad mayor de 83 años y el deterioro mental fueron factores de riesgo en el límite de significación estadística (p<0,05). Solo 42 pacientes (37,8%) vivían al año de la fractura. Conclusiones: El tratamiento conservador de las fracturas de cadera conlleva una elevada mortalidad al año de la fractura, siendo el principal factor de riesgo el estado general previo (AU)


Objective: To identify risk factors associated with increased mortality in elderly patients not operated after suffering hip fracture. Materials and methods: A one-year prospective study in 111 patients suffering hip fracture and not operated. The inclusion criteria were age over 60 years, not suffering a pathological fracture and not dying during hospital stay. All were followed for one year or until death. The risk factors analysed in the study were: age, sex, general health condition, mental impairment, performance status prior to the fracture and type of fracture. Results: The main risk factor was the general condition impaired before the fracture. The age over 83 years and mental impairment were borderline statistically significant risk factors (p<0.05). Only 42 patients (37.8%) lived at one year of the fracture. Conclusions: : Conservative management of hip fractures involves a high mortality at one year of the fracture, the previous general condition being the primary risk factor (AU)

Objetivo: Identificar los factores que pudieran conllevar un aumento de mortalidad en los pacientes de más de 60 años intervenidos de fractura de cadera. Material y método: Realizamos un estudio prospectivo de 90 pacientes para identificar en nuestro entorno los factores de riesgo relacionados con el aumento de la mortalidad de los pacientes de edad avanzada que, tras una fractura de cadera, fueron tratados mediante cirugía. Los criterios de inclusión fueron: tener más de 60 años, no tener una fractura patológica y no haber fallecido durante el ingreso. Todos ellos fueron seguidos durante 1 año o hasta su defunción. Los factores de riesgo analizados en el estudio fueron: edad, sexo, estado general de salud, deterioro mental y estado funcional previo a la fractura y el tipo de fractura. Conclusiones: El sexo y el estado general previo fueron variables de riesgo que mostraron diferencias estadísticamente significativas para la mortalidad al año, mientras que la edad y el estado mental antes de la fractura quedaron en el límite de significación (p<0,05). El estado funcional previo y el tipo de fractura no se mostraron como factores de riesgo (AU)


Purpose: To identify factors that could be associated to increased mortality in patients over 60 years of age with a hip fracture that undergo surgery. Material and method: This is a prospective study of 90 patients carried out with the aim of identifying what are in our environment the risk factors associated to increased mortality in elderly patients subjected to surgery further to sustaining a hip fracture. Inclusion criteria were as follows: being older than 60 years of age, not having a pathological fracture and staying alive during hospitalization. All patients were followed up for one year or until their passing away. Risk factors analyzed in the study were: age, gender, general health status, mental impairment and functional status prior to fracture, as well as fracture type. Conclusions: Gender and prior health status were the risk variables for which statistically significant differences were observed in terms of mortality at one year. In contrast, age and pre-fracture mental status stayed just below the statistical significant threshold for p<0.05. Prior functional status and fracture type were not identified as risk factors (AU)

INTRODUCTION: The most frecuently tests used to study the vestibular system, with videonystagmographic register, are the caloric and rotatory ones. MATERIAL AND METHODS: We have carried out a comparative study of the kinetic tests through a sample of 41 patients without vestibular pathology, stratified by age and gender. The performed rotational tests have been: Constant/cycles, postrrotatory test, increasing, decreasing and constant test. RESULTS: We have not observed age or gender influence on the results. We give the numeric results of these tests. CONCLUSION: The obtained data allow to conclude that the information given by the increasing and decreasing pendulous test is similar, phenomenon that doesn't happen in the rest of the practiced tests. We also study the habituation phenomenon to a know stimuli. We point out the importance of each laboratory to have their tests done previously in a normal control group in order to compare the results when performing them in pathological patients.

Introducción: Los test con registro videonistagmográfico más utilizados para el estudio del sistema vestibular son las pruebas calóricas y las cinéticas o rotatorias. Material y Métodos: Hemos efectuado un estudio comparativo de las pruebas cinéticas a través de una muestra de 41 pacientes sin patología vestibular, estratificados por edad y sexo. Las pruebas rotatorias practicadas han sido: constante/ciclos, postrrotatoria, creciente, decreciente y constante. Resultados: No hemos observado influencia de edad o sexo sobre los resultados. Se aportan los resultados numéricos de estas pruebas. Conclusiones: Los datos obtenidos permiten concluir que la información aportada por la prueba pendular creciente y decreciente son similares, fenómeno que no ocurre en el resto de las pruebas. Estudiamos también el fenómeno de habituación a un estímulo mantenido. Resaltamos la importancia de que cada laboratorio efectúe sus test a un grupo control normal para utilizarlo como referencia para estudiar a pacientes patológicos

Objetivos. La diferenciación de las células T en los patrones Th1 o Th2 según su patrón de producción de citocinas se ha demostrado muy importante en la regulación de las respuestas inmunes. Hemos estudiado si existe una diferencia entre sujetos controles y pacientes con melanoma en la expresión de estas citocinas, tanto en sangre periférica (mediante citometría de flujo) como en biopsias de los tumores (mediante RTPCR cuantitativa a tiempo real).Métodos. En la primera parte del estudio se incluyeron 25 pacientes: 6 eran controles y 19 habían sido diagnosticados de melanoma. Para la citometría de flujo se obtuvieron muestras de sangre de los 25 pacientes y se realizó una activación durante 4 horas con PMA + ionomicina en presencia o ausencia de un inhibidor de la secreción de proteínas (GolgiStop). Tras realizar un marcaje de superficie (CD3-Cy5+CD8-FITC) y una fijación y permeabilización (CytoFix-CytoPerm) las células fueron teñidas con anticuerpos marcados con ficoeritrina frente a las citocinas caracteríticas del patrón Th1 (IL-2, IFN, TNF-) y frente a las del patrón Th2 (IL-4, IL-10). En la segunda parte del estudio se incluyeron ocho biopsias cutáneas: dos controles, tres melanomas cutáneos localizados y tres metástasis cutáneas de melanoma. Tras extraer el ARN total, se estudiaron mediante una técnica de RT-PCR cuantitativa a tiempo real los tránscritos (mARN) de las siguientes citocinas: IL-2, IFN- , TNF-, IL-4, IL-5, IL-10.Resultados. Los datos más relevantes de la primera parte del estudio se relacionan con la producción de IFN y de IL-10. El porcentaje de células productoras de IFN era significativamente menor en los pacientes con melanoma, independientemente de su estadio, en relación con los controles. La producción de IL-10 se encontraba significativamente elevada en los pacientes con melanoma en comparación con los donantes sanos. Se observó una tendencia a un aumento en la producción de IL-10 en los estadios más avanzados de la enfermedad. La segunda parte del estudio mostró la existencia de un patrón Th2 o Th0 en las biopsias tanto de melanomas localizados como en las metástasis cutáneas. Conclusiones. Nuestros datos sugieren que los linfocitos activados de los pacientes donantes sanos tienden a exhibir un fenotipo Th1, mientras que en los pacientes con melanoma se observa un aumento en la proporción de linfocitos productores de una citocina característica del patrón Th2 como es la IL-10, con reconocidas propiedades inmunosupresoras. El análisis del propio tumor apoya estos resultados, ya que el patrón hallado con mayor frecuencia es el Th2 (AU)

Post-transplant cure tubular necrosis (ATN) represents the most frequent cause of delayed graft function in the immediate post-transplant period. Several causes have been associated with the development of post-transplant ATN such as donor and recipient ages, cold-warm ischemia times, HLA mismatches, and postoperative hypotension. In the present study, we retrospectively evaluated the role of secondary hyperparathyroidism and high parathyroid hormone (PTHi) blood levels in the development of post-transplant ATN. One hundred patients submitted to cadaveric renal transplant between January 1992 and March 1993 in our unit were included. Twenty-seven patients (27%) developed post-transplant ATN and seventy-three (73%) did not. Post-transplant ATN was significantly associated with gender (p < 0.01), recipient age (p < 0.01), number of transplantations (p < 0.01), time on hemodialysis (p < 0.001), cold ischemic time (p < 0.05) and PTHi levels (p < 0.001). The bivariate and multivariate statistical analyses demonstrated that the development of post-transplant ATN was significantly more frequent in females; retransplanted patients, patients with a time on dialysis of more than 5 years, recipients over 60 years old, patients with a PTHi blood level higher than 240 pg/ml (4 times normal level) and a cold ischemia time of more than 18 h. Based on these results, we conclude that high PTHi blood levels in the renal transplant recipients represent a relevant factor in the development of post-transplant ATN. The administration of intravenous pulsed of 1,25(OH)2D3 and/or a calcium channel blocker in the perioperative period could be useful to decrease the incidence and severity of post-transplant ATN in these patients.

Disturbances of sleep are frequent and varied in patients with Parkinson's disease. In an attempt to find out about these disturbances, we carried out interviews using the Vanna and Mazzuia questionnaire, modified for forty-five sufferers of Parkinson's disease, and forty healthy adults. We researched sleep habits and disturbances, as well as the consumption of hypnotics. We found that both groups had similar habits, although those with PD altered according to the stage of development of the disease, thus difficulty in staying sleep and parasomnia were more frequent in PD sufferers and worsened in the most advanced cases. On the other hand the quality of night sleep and the consumption of hypnotics interfered in the daytime efficiency of those suffering from Parkinson's Disease.

We studied by Echocardiographic-Doppler 114 consecutive intravenous drugs addicts (IVDA); 91 were positive human immunodeficiency virus (HIV+) and 23 negatives. We classified them in five groups; beginning the negative HIV as group 0, and groups I to IV stratified according the Central Disease Control (CDC) classification. We compared the cardiac abnormalities founded between themselves and a control group presumed healthy persons of similar age. The cardiac cavities dimensions showed a statistic significant increased left ventricular end-systolic and diastolic diameters, right ventricular diameter, posterior wall and interventricular septum thickness and aortic root diameter compared with the control group; but all were in the normal range for age. The left ventricular fractional shortening was statistically different from control group related the other groups, and the group IV related other. The existence and severity of pericardial effusions were directly related to the illness stage. We founded moderate pericardial effusions in 25% patients in the 0 to III groups, increasing until 50% in the group IV. The presence of valvular vegetations, nearly 30% in our series, ought to the IVDA. We did not found relationship between the severity of valvular incompetence and the illness stage. We recorded a excellent correlation between the ratio T4/T8 lymphocytes with the progress of illness and the existence and severity of cardiac abnormalities.
