    Full Text Available La presente investigación fundamenta en la clínica psicoanalítica el estudio de dos casos de tres personas diagnosticadas con IRT que reciben tratamiento de hemodiálisis, en razón a que dadas las características y el aumento de los reportes que se presentan, ya esto se considera un problema de salud pública. El objetivo principal es describir las características dinámicas del proceso de duelo en pacientes con IRT en un centro de terapia renal de la ciudad de Cartagena. El procedimiento metodológico empleó un diseño de tipo cualitativo; la investigación se desarrolló con un diseño clínico mediante el estudio de casos, y fundamentada en la hermenéutica psicoanalítica. Todo esto respaldado en la historia clínica, la entrevista semiestructurada individual y familiar, los test proyectivos, test del dibujo de la figura humana Machover y TAT de Murray, para la debida integración de los análisis. Se concluye que predominan funciones fallidas de los progenitores y que son individuos provenientes de familias psicosomáticas, que utilizan la enfermedad para obtener un beneficio secundario.

    Full Text Available OBJETIVO: Analisó el costo-efectividad en intervenciones para pacientes con insuficiencia renal crónica terminal (IRCT en términos de los costos económicos de cada intervención, los años de vida ganados y la calidad de vida que generan tres alternativas comparables y mutuamente excluyentes: diálisis peritoneal contínua ambulatoria (DPCA, la hemodiálisis (HD y el trasplante renal (TR. MÉTODO: El diseño del estudio fue de tipo longitudinal. Los costos de cada intervención se determinaron mediante la técnica de manejo de caso promedio. Las medidas para evaluar los criterios de efectividad elegidos fueron la probabilidad de sobrevida y el Año de Vida Ajustado por Calidad (QALY, Quality Adjusted Life Year medido por el Indice de Rosser. RSULTADOS: Los costos de manejo anual de caso fueron: diálisis peritoneal $5,643.07, hemodiálisis $9,631.60 y trasplante $3,021.63. En cuanto a la efectividad, la sobrevida del injerto de trasplante renal resultó de 89,9% y 79,6% a uno y tres años respectivamente, mientras que los pacientes sometidos a DPCA tienen una sobrevida de 86,2% y 66,9% a un año y a tres años respectivamente. En cuanto a los QALY's, los resultados para cada intervención fueron: DPCA 0,879; HD 0,864; y para el TR 0,978. CONCLUSIÓN: La intervención más costo-efectiva resultó el trasplante renal con un coeficiente de 3,088.69, seguido de la DPCA y la hemodiálisis, cuyos coeficientes fueron de 6,416.95 y 11,147.68 respectivamente. Por lo tanto se recomienda promover y utilizar el trasplante renal como la intervención más costo-efectiva para pacientes con IRCT.

    La insuficiencia renal crónica (IRC) se define como el deterioro lento y progresivo de las funciones renales debido a la destrucción irreversible de las nefronas. El resultado es un descenso gradual de la velocidad de filtración glomerular, de la función tubular y de la capacidad de reabsorción, que da lugar a la pérdida del control hidroelectrolítico, a trastornos aci­dobásicos y a problemas sistémicos. Suele producirse una progresión gradual hacia la uremia. Evoluciona en periodos de tiempo...

    Full Text Available RESUMEN:La insuficiencia renal aguda es un sindrome que característicamente cursa con niveles plasmáticos elevados de urea y creatinina. Sin embargo, hay situaciones clínicas en las cuales este sindrome puede cursar con un incremento de la creatininemia sin presentar elevación de la uremia.En este reporte presentamos un caso clínico de una insuficiencia renal aguda con uremia normal secundaria a una pielonefritis aguda en un paciente con riñón único. El paciente presentaba una elevada excreción fraccional de urea lo cual podía explicar su uremia normal pese a estar cursando una caída del filtrado gomerular. Dicha excreción de urea elevada fue interpretada como secundaria a una diabetes insipida nefrogénica y una alteración en el recirculado intra-renal de la urea ambos producto de la pielonefritis aguda. Concluimos que la pielonefritis aguda en un paciente mono-reno puede presentarse con un patrón de insuficiencia renal aguda con uremia normal. SUMMARYAcute renal failure is a syndrome that usually runs with an increase in creatinine and urea plasma levels. However, there are clinical situations in which this syndrome may run with an increase in plasma creatinine keeping normal the urea one.In this report we present a case of acute renal failure with normal plasma urea level secondary to an acute pyelonephritis in a single kidney patient. The patient had an increased fractional excretion of urea which could explain the normal plasma urea levels found despite of his reduced glomerular filtration. This increased urea excretion state was interpreted as a consequence of the nephrogenic diabetes insipidus and alteration of the intra-renal urea reciclying process that the acute pyelonephritis induced. In conclusion: Acute pyelonephritis in a single kidney patient can appear as a pattern of acute renal failure with normal plasma urea levels.

    Full Text Available La insuficiencia renal aguda, es una condición común en la Unidad de Cuidados Intensivos de Adultos (UCIA y probablemente una consecuencia de la enfermedad crítica que se asocia a resultados clínicos adversos, altos costos y una mortalidad de más del 50%, sobre todo si se requiere tratamiento de reemplazo renal. El objetivo fue determinar la incidencia de insuficiencia renal aguda en pacientes ingresados a la UCIA. El estudio fue prospectivo, longitudinal, observacional, en 101 pacientes ingresados en la UCIA del Hospital Regional de Cuilapa. Se diagnosticaron 101 pacientes durante el periodo de estudio con insuficiencia renal aguda represento el 27.4% del total de pacientes internados (368 en el servicio en un año. La incidencia de mortalidad en pacientes que requieren terapia de reemplazo renal y se encuentran en ventilación mecánica es del 100%. Del total de pacientes estudiados, según la escala Akin, se encontró que el 49.5% de los pacientes correspondían a grado II, aunque el grado I también fue frecuente (29%, y que el 22 % de los pacientes correspondían a grado III. La patología que mayormente se asoció al desarrollo de insuficiencia renal aguda fue sepsis grave con un 31%, seguido de pacientes sometidos a cirugía mayor e hipovolemia con el 21 y 18% respectivamente. Se halló una incidencia aumentada de insuficiencia renal aguda comparado con estadísticas internacionales, cuya etiología fue mayormente causada por procesos sépticos.

Las siguientes son las principales características de la IRA en el anciano: carácter multifactorial, presentación clínica atípica, fragilidad tubular, patrón de síndrome intermedio y poca fiabilidad del examen físico y de los índices urinarios en la interpretación de su etiología. Las medidas de profilaxis y rehidratación siguen siendo los mejores tratamientos de la IRA en el viejo. La biopsia renal y la diálisis tienen el mismo rol tanto en el grupo senil como en el joven.ABSTRACTACUTE RENAL FAILURE IN THE ELDERLY: PEARLS FOR ITS ASSESSMENT AND TREATMENT.Acute renal failure (ARF is a frequent disorder in the elderly, and this phenomenon is due to the senescence process, reduced metabolization of drugs, increased exposure to polypharmacy and systemic diseases of the aged group. The following are the main characteristics of the ARF in the elderly: mulfactorial, atypical presentation, tubular frailty, intermediate syndrome pattern, low reliable physical examination and urinary indeces. Profilaxis and rehydration are the best treatments for ARF in the old population. Renal biopsy and dialysis have the same role in young and old people.

    Full Text Available Se describe la presentación de un caso de leptospirosis producida por L. pomona en un paciente de 20 años de edad, trabajadora habitual en un molino de arroz y caracterizado por un síndrome de insuficiencia renal y hepática. El cuadro clínico consistió principalmente en malestar general, anorexia, vómito, fiebre, diarrea, ictericia y hemorragias subconjuntivales. Los exámenes de laboratorio mostraron alteraciones, en los niveles de nitrógeno ureico, creatinina, depuración de creatinina, concentración de cloro, fosfatasa alcalina y bilirrubina directa lo cual podría indicar un daño en el funcionamiento hepático y renal. Las alteraciones en la velocidad de sedimentación, hemoglobina, hematocrito y leucocitos (Tabla 1 explican la anemia e infección ocasionada por la L. pomona en la paciente. El diagnóstico de leptospirosis fue confirmado por el aislamiento del microorganismo de la orina a pesar de no haber detectado anticuerpos en el suero de la paciente. Se pone en evidencia la necesidad de realizar siempre el diagnóstico diferencial con leptospirosis en todo síndrome hepatorrenal, especialmente en los casos con antecedentes epidemiológicos o que por la sintomatología clínica se sospeche la infección.

    Full Text Available

    Los mecanismos del da no celular en la insuficiencia renal aguda Incluyen alteraciones en la producción de energía, la permeabilidad celular y el transporte de calcio. Dichas alteraciones producen cambios progresivos en la estructura celular que pueden ser reversibles si desaparece la causa que llevó a la falla renal, excepto cuando se alcanza la fase final de la lesión de la membrana y se llega a necrosis celular. Este mismo fenómeno probablemente ocurre tambIén en situaciones clínicas.

    The mechanisms of cellular damage In acute renal failure Include alterations In energy production, cell membrane permeability and calcium transport. These changes lead to progressive damage of the whole cellular structure which In general can be reversible If the precipitating cause disappears, except when the final stages of cell membrane lesion take place and cellular necrosis has occurred. This phenomenon probably applies for the clinical settling as well.

    Full Text Available El test de furosemida consiste en una prueba de fisiología renal que se utiliza para evaluar la capacidad de los túbulos colectores para secretar potasio. Dicho estímulo está mediado por acción de la hormona aldosterona, cuyos niveles séricos se elevan tras el suministro de furosemida. Si bien el patrón de respuesta de este test ha sido descrito en niños y jóvenes sanos, no se lo ha hecho aun en pacientes portadores de insuficiencia renal crónica. Por este motivo se decidió realizar el siguiente estudio a fin lograr su descripción.Material y Método: Se estudiaron veintiséis voluntarios jóvenes (edad: 20 - 40 años, sometidos a una dieta baja en potasio (40 mmol de potasio/día: veinte de ellos eran jóvenes sanos (no presentaban ninguna enfermedad ni tomaban ninguna medicación, y el resto eran pacientes jóvenes portadores de enfermedad renal crónica estadío II/III (filtrado glomerular (FG entre 83,1 ml/min - 39,2 ml/min secundaria a glomerulopatía (diagnóstico por biopsia renal. Ninguno de los pacientes estudiados era portador de diabetes mellitus, obstrucción urinaria, ni estaban en tratamiento con drogas potencialmente inductoras de diskalemia: diuréticos, inhibidores de la enzima convertidora, y antagonistas del receptor de angiotensina II. Desde el comienzo del test y hasta 180 minutos post recibir una dosis única de furosemida endovenosa (1 mg/kg, se obtuvieron muestras de orina y sangre para medir niveles de creatinina y potasio. A partir de estos datos se calculó la excreción fraccional de potasio (EFK correspondiente a cada muestra. El análisis estadístico fue realizado aplicando el test de Student.Resultados: Si bien no hubo diferencia estadísticamente significativa ni en el valor basal (pre-furosemida, ni promedio (post-furosemida de la EFK, entre los sujetos sanos y los pacientes con insuficiencia renal crónica (IRC: EFK basal 16,4 ± 8,6% ( IRC vs 11,5 ± 4,6% (sanos (p= NS; EFK promedio 40,8 ± 3

The aim of the present study was to evaluate alternative biochemical methods to bone biopsy, to evaluate changes in bone remodeling in renal patients. Intact PTH (iPTH and bone markers were measured in 43 predialysis (PD, 49 hemodialysis patients (HD and 185 controls. bCTXs, bone alkaline phosphatase (bAL, iPTH were higher and creatinine clearance (Ccr was lower in PD and HD compared with controls (p40 ml/min. bCTXs (p<0.05 in PD and bCTXs and bAL in HD patients were higher than controls, even when iPTH was within normal range (<65 pg/ml. Patients with severe secondary hyperparathyroidism showed higher bone markers than patients with normal or moderately increased iPTH (p<0.001. These results suggest that even when there is no increase in iPTH, bone remodeling increases (possibly due to other factors exhibiting higher bone resorption, and bCTXs would seem to be an adequate non-invasive tool to assess early bone changes in CRF and prevent future fractures. Bone marker measurements in ROD would be useful to identify patients who may require bone biopsy. However, further studies comparing both methods must be performed before replacing bone biopsy with serum b-CTX.

    Full Text Available Objetivo: Identificar las creencias y representaciones sobre la insuficiencia renal crónica (IRC en pacientes, población general y expertos. Metodología: Estudio descriptivo transversal que analiza una muestra de 120 participantes seleccionados por muestreo no probabilístico por cuotas. Se crearon cinco grupos de estudio en función de su nivel de interacción con la enfermedad. La herramienta utilizada fue el Cuestionario de Creencias Sobre la Enfermedad. Resultados: Identidad, Controlabilidad, Mutabilidad, Responsabilidad Personal y Azar no presentan diferencias significativas entre los grupos estudiados. El factor Causas muestra diferencias estadísticamente significativas entre el grupo de pacientes con universitarios de ciencias de la salud y expertos (p<0,001 y entre otros universitarios con universitarios ciencias de la salud y expertos (p<0.001. El factor Incapacidad muestra diferencias significativas entre pacientes, universitarios y población general (p<0,001 y entre expertos con otros universitarios y población general (p<0,001. Los pacientes ofrecen un menor número de síntomas asociados tanto a la IRC como a la hemodiálisis (HD. Y en cuanto a las causas, las de origen biológico y conductuales son las más consideradas por todos los grupos. Solo el grupo de pacientes en HD considera el azar factor causal de la enfermedad. Conclusiones: En oposición al modelo científico, pacientes y población general comparten la idea de que la IRC es curable, depende en gran medida del azar y de hábitos de conducta y es menos grave de lo que opinan expertos. La experiencia con la enfermedad aporta más información (no necesariamente conocimiento que es recordada en función de la utilidad para lograr un mayor bienestar o una mejora de los cuidados.

    Full Text Available La insuficiencia renal crónica es una de las patologías de alto costo con mayor impacto financiero para el Sistema General de Seguridad Social en Salud de Colombia. La alta concentración de casos de alto costo en algunas empresas del sector hizo necesaria la redistribución de recursos y pacientes para contrarrestar el desequilibrio financiero. El artículo señala que la inducción a la demanda es la principal falla de este mercado oligopólico. Expone algunas hipótesis sobre los incentivos de las empresas y muestra que la entidad reguladora debe intervenir en el control de los precios y la calidad y, sobre todo, adaptar medidas orientadas a prevenir la enfermedad.

    Conclusiones: la prevalencia de insuficiencia renal determinada por la depuración de creatinina, es alta tanto en hombres como en mujeres evaluados en la clínica de falla cardiaca, lo cual conduce a replantear los esquemas de manejo dependiendo de la función renal ya que algunos de los medicamentos utilizados son nefrotóxicos o incrementan los niveles de potasio. Por lo tanto, la valoración de la función renal mediante la utilización de la depuración de creatinina por medio de la fórmula de Cockcroft, puede ser más conveniente que sólo basarse en la creatinina, por lo cual se recomienda realizarla en todos los pacientes que se estén siguiendo en las clínicas de falla cardiaca al igual que al considerar cambios en el esquema de manejo médico.

    Full Text Available La polineuropatía urémica es la complicación neurológica más frecuente de la insuficiencia renal crónica, y son insuficientemente conocidos su prevalencia, síntomas y patrones neurofisiológicos de expresión en la población pediátrica. Es por ello que se estudiaron 23 pacientes en edades comprendidas entre 7 y 21 años, con insuficiencia renal crónica en sus diferentes grados y 23 niños supuestamente sanos, buscando la presencia de neuropatía periférica clínica o subclínica. Se realizó examen físico general y neurológico, así como la medición de las velocidades de conducción motora y sensitiva. Los síntomas predominantes fueron el dolor a la marcha (55,5 % y las parestesias (44,4 %, y fueron más frecuentes en el grupo de pacientes dialíticodependientes. La función nerviosa periférica estuvo alterada en todos los grupos estudiados, y existió correlación significativa entre la velocidad de conducción sensitiva y los valores medios de urea, creatinina y filtrado glomerular. Se hallaron diferencias significativas entre las medias de la velocidad de conducción sensitiva de los niños de los grupos predialítico, dialíticodependiente y el grupo control, y entre los grupos predialítico y con transplante renal no existieron diferencias significativas.Uremic polyneuropathy is the most frequent neurological complication of the chronic renal failure but its prevalence, symptoms and neurophysiological patterns of expression in the pediatric population are not well known. This is the reason why 23 patients aged 7-21 years with chronic renal failure at different stages and 23 supposedly healthy children were studied to look for clinical or subclinical peripheral neuropathy. General physical and neurological exams were made and sensory and motor conduction velocities were measured. The prevailing symptoms were pain on walking(55,5% and paresthesias (44,4% mainly found in dialysis-dependent patients. All the studied groups

    confirmando esa observación. La importancia del EG en anestesia puede ser resumida un uno de sus aspectos principales, el ayuno preoperatorio. El retardo en el vaciamiento puede causar estasis y aumentar el riesgo de vómito y aspiración pulmonar. La posibilidad de existir retardo del vaciamiento en urémicos nos atrae. Quejas dispépticas son comunes en estos pacientes y podrían ser explicadas por la dificultad de vaciamiento gástrico. A pesar de las evidencias, la literatura es muy controvertida en este aspecto. No existe un consenso en cuanto a los resultados obtenidos. Diferencias en el método de estudio utilizado podrían explicar esos resultados, observados en estudios clínicos y experimentales. El objetivo de este estudio fue ver nuevamente algunos aspectos importantes del síndrome dispéptico en pacientes con insuficiencia renal crónica (IRC terminal, con énfasis en el retardo del EG. CONTENIDO: Se abordarán los aspectos básicos relacionados a la fisiología del EG, los métodos más empleados para el estudio del EG, el síndrome dispéptico y la uremia y el vaciamiento gástrico en la insuficiencia renal crónica. CONCLUSIONES: El EG es un proceso fisiológico complejo de transferencia del alimento del estómago para el duodeno, cuyos mecanismos todavía no se conocen bien. La cintilografía, utilizando comidas con radio fármacos, es el examen más utilizado para el estudio del EG. Un porcentaje expresivo de pacientes con IRC terminal presenta retardo en el EG. Posiblemente otros mecanismos, además de la uremia, involucrando la función motora gástrica, están involucrados en esta disfunción.BACKGROUND AND OBJECTIVES: The first reference to delayed gastric emptying (GE was made by Grodstein in 1979. Other studies have since been published, not always confirming his work. The importance of GE in anesthesia can be resumed by one of its main aspects, preoperative fasting. Delayed gastric emptying can lead to stasis and increase the risk of vomiting and

Fueron variables para estudio, edad, sexo, peso corporal en kilogramos, hemoglobina, tensiones arteriales sistólica y diastólica, frecuencia cardíaca, complicaciones posinducción y las dosis de tiopental sódico en miligramos por kilogramos. Se utilizó análisis de varianza. Fueron significativas las variaciones con p Fifty six medical histories with the anesthesiology protocols of 26 patients with chronic renal failure (CRF and of 30 sound patients were reviewed. Age, sex, body weight in kg, haemoglobine, systolic and diastolic arterial tensions, heart rate, postinduction complications, and thiopental sodium doses in mg x kg were the variables used in this study. The variance analysis was used. Variations with p < 0,05 were significant. The sample was divided into patients without CRF (group I and with CRF (group II. There were no differences between the thiopental sodium anesthetic doses of both groups (4,59 + 3,88 mg/kg, group I and 5,89 + 4,15 mg/kg, group II. Arterial tension descended more in patients from group II as a result of anesthesia induction. This variation did not mean a greater incidence of hypotension between both groups (16,6 % in I and 15,3 % in II. It is concluded that in our enviroment the necessary dose of thiopental sodium to induce anesthesia in patients with and without CRF was not statistically different. However, the fal of arterial tensions was more important in group II. It is recommended to take more precaution in the administration of thiopental sodium to these patients

    Full Text Available Acute renal failure (ARF is one of the main renal disorders, which is characterized by deterioration (in hours or days of the glomerular filtration rate. Serum creatinine is the marker typically used in clinical practice for the diagnosis and monitoring of the IRA. However, it has the disadvantage of being a late marker and influenced by multiple variables. In order to overcome this limitation new biomarkers of AKI were obtained, such as interleukin 18 (Interleukin 18, gelatinase-associated lipocalin neutrophil (neutrophil gelatinase-associated lipocalin, kidney injury molecule (kidney injury molecule and cystatin C (cystatin-C, which have higher sensitivity, specificity and ability to determine the location of the damage and the IRA evolution respect to serum creatinine.

    The numerous musculoskeletal changes associated with chronic renal insufficiency (CRI) are detected with increasing frequency since hemodialysis and kidney transplantation have prolonged the survival of these patients. These signs have been divided into two large groups. The first includes secondary hyperparathyroidism (bone resorption, periostitis and brown tumors), osteoporosis, osteosclerosis, osteomalacia and vascular and soft tissue calcification, all of which are grouped under the term renal osteodystrophy. the second group is composed of miscellaneous disorders including aluminum poisoning, amyloid and crystal deposition, destructive spondyloarthropathy, tendon rupture, infection and avascular necrosis. These changes are less common and occur especially in patients under prolonged hemodialysis or kidney transplant recipients. The detection of musculoskeletal involvement in CRI patients has a considerable impact on their clinical management. The present article reviews the radiological signs of these changes, including representative images that will aid in their recognition. (Author) 33 refs.

    Full Text Available La reciente identificación y clonación del receptor sensor de calcio (RSCa ha permitido tener una mejor comprensión de la regulación normal del metabolismo del calcio y entender un número de trastornos relativamente poco frecuentes del metabolismo mineral. En la glándula paratiroides el RSCa es el mecanismo responsable de modular la liberación de la hormona paratiroidea en función del nivel de calcio extracelular. Este descubrimiento también ha permitido desarrollar drogas que imitan o potencian las acciones del calcio extracelular sobre el RSCa (llamadas calciomiméticos que disminuyen la secreción de paratohormona sin incrementar el calcio sérico. Los calciomiméticos de última generación son pequeñas moléculas orgánicas que actúan como moduladores alostéricos del RSCa y se encuentran en su fase inicial de desarrollo clínico. A pesar de que la experiencia obtenida con estas drogas hasta ahora es limitada, ellas han mostrado ser efectivas para reducir los niveles de paratohormona en pacientes con hiperparatiroidismo secundario a fallo renal terminal sin inducir efectos secundarios de importancia. Es por ello que los compuestos calciomiméticos tienen un considerable potencial como nuevas drogas para el tratamiento del hiperparatiroidismo secundario y de la enfermedad ósea secundaria a la insuficiencia renal.The recent discovery and cloning of the extra cellular calcium sensing receptor (CaSR has allowed a better understanding of the regulation of normal calcium metabolism and of rare disturbances in mineral metabolism. In the parathyroid glands the CaSR is responsable for modulating parathyroid hormone release as a function of the extra cellular calcium level. This discovery has allowed the development of drugs that mimics or potentiates the actions of extra cellular calcium on the CaSR, called calcimimetics that decrease parathyroid hormone secretion without increasing serum calcium.

El objetivo de este estudio fue caracterizar el estado nutricional de niños con esta enfermedad que requirieron terapias de reemplazo renal. MÉTODOS. Se realizó un estudio retrospectivo y transversal que incluyó a los pacientes ingresados por insuficiencia renal aguda en dos hospitales pediátricos de Santiago de Cuba entre diciembre de 2006 y diciembre de 2008. Se analizó edad, sexo, etiología, terapia de reemplazo renal, causa del uso de nutrición parenteral, evaluación nutricional según tablas cubanas de percentiles y parámetros antropométricos (edad, peso, talla y aporte de nutrientes parenterales. RESULTADOS. Eventos prerrenales fueron la causa de la insuficiencia renal aguda en el 44,4 % de los casos, y renales y posrenales, en el 33,4 y 22,2 %, respectivamente. Como método de depuración renal se utilizó la diálisis peritoneal en el 66,6 % de los casos y la hemodiálisis en los restantes pacientes. Las principales causas que motivaron la nutrición parenteral fueron las afecciones quirúrgicas, los estados hipercatabólicos, la hemorragia digestiva y la pancreatitis, en orden decreciente. Cuatro pacientes fueron evaluados como de bajo peso. CONCLUSIONES. El aporte promedio de proteínas y lípidos estuvo por debajo de los aportes nutricionales establecidos, y el aporte de kilocalorías fue superior a lo recomendado.

    Full Text Available Introducción: El desarrollo de disfunción renal en el contexto de una falla cardíaca aguda se conoce como síndrome cardiorrenal (SCR tipo 1. El empeoramiento de la función renal (EFR durante la internación es un predictor de mal pronóstico. La cistatina C ha surgido como un marcador de función renal alternativo a la creatinina. Objetivo: Demostrar la utilidad clínica de la cistatina C como predictor de EFR y factor pronóstico en pacientes con insuficiencia cardíaca aguda y sin disfunción renal evaluada por creatinina al ingreso. Material y métodos: Se llevó a cabo un estudio observacional, prospectivo, de pacientes consecutivos con diagnóstico de insuficiencia cardíaca aguda y sin disfunción renal, definida como un valor de creatinina < 1,3 mg/dl al ingreso. Se realizó un dosaje de cistatina C al ingreso. El punto final primario fue EFR y los secundarios fueron mortalidad hospitalaria, mortalidad total y reinternación por insuficiencia cardíaca. Resultados: Se incluyeron 166 pacientes con una mediana de edad de 85 años (IIC 77,7-89. La incidencia de EFR fue del 29,7%, con una mortalidad hospitalaria del 3,1% y una mortalidad total del 24,4%. La mediana de seguimiento fue de 193 días. El valor de cistatina C fue significativamente mayor en los pacientes que desarrollaron EFR (1,72 ± 0,58 mg/dl vs. 1,51 ± 0,41 mg/dl; p = 0,03 y en los pacientes que murieron en el seguimiento (1,76 ± 0,49 mg/dl vs. 1,51 ± 0,46 mg/dl; p = 0,004. La cistatina C resultó un predictor independiente de mortalidad (OR 3,03, IC 95% 1,22-7,47 y de EFR (OR 2,38, IC 95% 1,02- 5,5 en el análisis multivariado.

    Full Text Available An experimental trial in 40 Wistar rats was done. The renal failure was induced by surgical ablation of 5/6 of the renal mass to 30 rats; 3 groups were formed and followed over a period of 2, 4, and 6 weeks. The remaining group of rats was used as control.Functional remainder state was evaluated by measurement of the Glomerular Filtration Rate (GFR and effective Renal Plasmatic Flow (RPF, Filtration Fraction (FF was also calculated. Lipid and protein oxidative damage were evaluated on the renal tissue. As markers of oxidative stress the levels of Malonildialdehyde (MDA and Advanced oxidation protein products (AOPP were determined. Progressive decreasing of GFR, RPF and FF were noted.

    A 12-year-old Congolese girl presented with acute renal failure, edema, hypertension, hemoptysis, hematuria, and proteinuria after a history of throat infection. Renal ultrasound showed kidneys of normal size, with increased echogenicity of the cortical parenchyma and decreased corticomedullary differentiation. Other additional investigations showed pancytopenia with decreased complement (low C3 and C4). Antinuclear antibodies were strongly positive, including anti-double stranded DNA. Renal biopsy confirmed severe grade IV lupus nephritis. She was treated with high-dose steroids, mycophenolate mofetil and hydroxychloroquine, in addition to hemodialysis. After one week of intensive treatment, diuresis recovered and dialysis could be stopped after six sessions. We describe an uncommon case of severe lupus nephritis, presenting with terminal renal failure. Since the rarity of this disease presentation, other more common diagnoses have to be considered. Once the diagnosis of lupus nephritis is established, a choice has to be made between the different induction treatment protocols. The patient's ethnic background and other supportive therapies, such as the need for dialysis, can help to make this choice.

    . Conclusiones: la prevalencia de insuficiencia renal determinada por la depuración de creatinina, es alta tanto en hombres como en mujeres evaluados en la clínica de falla cardiaca, lo cual conduce a replantear los esquemas de manejo dependiendo de la función renal ya que algunos de los medicamentos utilizados son nefrotóxicos o incrementan los niveles de potasio. Por lo tanto, la valoración de la función renal mediante la utilización de la depuración de creatinina por medio de la fórmula de Cockcroft, puede ser más conveniente que sólo basarse en la creatinina, por lo cual se recomienda realizarla en todos los pacientes que se estén siguiendo en las clínicas de falla cardiaca al igual que al considerar cambios en el esquema de manejo médico.Background: patients with heart failure have an increased morbidity to the extend that they present impaired renal function, taking as a predictor of adverse events the elevation of creatinine clearance. Methods: a descriptive analysis of patients attending the heart failure clinic of the Shaio Clinic from January 1997 until October 2009 was realized, in order to know their renal function through creatinine clearance using the Cockcroft formula. Risk factors taken into account were the presence of hypertension, diabetes mellitus, smoking and dyslipidemia, and some drugs that can affect renal function, such as spironolactone, digitalis, angiotensin-converting enzyme and antagonists of angiotensin II receptors were also assessed, as well as the etiology correlated with creatinine clearance. Results: 1,123 patients were registered in the data base, of whom 557 (49.6% meet the inclusion criteria, and of these 461 (82.8% present impaired renal function. 301 (65% are males and 160 (35% female.

    Full Text Available La enfermedad renal crónica implica un proceso irreversible en la reducción del funcionamiento del tejido renal por lo que la ha llevado a ser un problema de carácter epidémico, donde las complicaciones son devastadoras para la calidad de vida en el paciente, dentro de éstas destacan las calcificaciones metastásicas que se producen por la retención de fósforo, disminución de los niveles de calcio y aumento de la paratohormona. El tratamiento mas adecuado es la paratiroidectomia subtotal con autoimplante, donde la sintomatología y la progresión de las alteraciones del metabolismo mineral se reduce y mejora el estado general del paciente. Se presenta un caso clínico de una paciente en diálisis peritoneal, con diagnóstico de calcificación metastásica abdominal, a la cual se le realiza una paratiroidectomia - subtotal con autoimplante, donde se observó una buena respuesta con disminución de la calcificación en forma progresiva. Al evaluar el caso clínico proponemos como enfermeras especialistas en el cuidado del paciente renal, establecer en los centros de diálisis un control semestral por enfermera, independiente de las sesiones de diálisis, donde podamos pesquisar con mayor privacidad y autonomía, las necesidades particulares de cada uno de estos pacientes contribuyendo precozmente a una mejor adherencia al tratamiento y retardo progresivo de las complicaciones propias de esta enfermedad.

    Full Text Available En la década de los 90 se descubrió un nuevo sistema de comunicación célula-célula, que consiste en la liberación de vesículas cargadas con partículas bioactivas (proteínas, mRNA, miRNA, metabolitos, etc. en el espacio extracelular. Este tipo de comunicación se ha conservado durante la evolución, hecho que justificaría que la mayoría de los tipos celulares puedan generarlas. Estas vesículas extracelulares (VE pueden regular diversos procesos fisiológicos, así como el desarrollo y progresión de enfermedades. En los últimos años se ha extendido el estudio de las VE generadas principalmente por células madre adultas o embrionarias, células sanguíneas, células del sistema inmune y nervioso, así como células tumorales. El análisis de VE en fluidos corporales ha sido utilizado como herramienta de diagnóstico en cáncer y recientemente para distintas enfermedades renales. Sin embargo, en esta revisión pretendemos analizar la importancia, función y posible aplicación clínica de las VE generadas por células madre en enfermedades renales y en trasplantes.

    Renal transplantation is the best therapeutic option for end-stage chronic renal disease. Assuming that it is more advisable if performed early, we aimed to show the clinical, social, and economic advantages in 70% of our patients who were dialyzed only for a short period. For this purpose, we retrospectively collected data over 28 years in 142 kidney transplants performed in patients with renal transplantation with renal failure, especially in developing countries such as Bolivia, where until last year, full public support for renal replacement therapy was unavailable.

    Full Text Available El proceso de voluntades anticipadas permite a los pacientes dar a conocer sus preferencias. Método: estudio cualitativo de subgrupos homogéneos con pacientes con enfermedad renal crónica en programa de diálisis a través de entrevistas semiestructuradas, con el objetico de conocer su deseo de participar en la toma de decisiones sanitarias, en particular las relacionadas con el final de la vida. Resultados: de mayo a diciembre de 2012 se entrevistaron a catorce pacientes, con una mediana de edad de 66 años. Creen que reciben una información adecuada, pero reconocen que no se les habla sobre el final de la vida o la retirada de diálisis. Creen que los médicos no hablan de ello porque están centrados en otras cuestiones y no quieren entristecerles. Quieren participar en la toma de decisiones y expresar sus preferencias. En caso de deterioro neurológico severo preferirían suspender la diálisis y recibir tratamiento para no tener dolor, en su casa si es posible. Sería conveniente integrar los cuidados paliativos en la asistencia de los pacientes en diálisis.

    Full Text Available The objective of this research was to identify coping strategies undertaken by patients with kidney failure on current dialysis. The approach chosen for this research was quantitative, since the empirical analytical paradigm, with a rate of descriptive design. The sample comprised 10 patients aged between 20 and 60 years, on current hemodialysis in Clinica de la Costa Renal Unit, Patients were intentionally selected besides their voluntary participation. Standardized questionnaire was used in Colombia to the stress of coping Sandin & Chorot. According to the results, the coping style they use, is focused on the problem with its three dimensions: focus on the problem, with a score of 80% of the population, also in the positive reappraisal with 80% of the population studied, and seeking support with 60% of the population, indicating that this group of patients take an active role, are still concrete steps, what they do to appropriately respond to changes and demands, and treatment imposed by the disease. It is then the religion as a coping style with a 60% higher in the standings. Religion belongs to the dimension of avoidance and escape, indicates that this sample perceived as a significant interference of their health condition on their physical function and consequently feel less vital, turns to their religious beliefs as a way of relief that the situation will improve.

    Purpose: An increased incidence of renal tumors has been observed in patients with end-stage-renal-disease (ESRD). The very strong association with acquired renal cystic disease (ACRD) and increased incidence of the renal tumors (conventional renal cell carcinoma (CRCC), papillary renal cell carcinoma (PRCC) or papillary renal cell adenoma (PRCA)) was reported. This study discusses the role of computed tomography (CT) in detecting renal tumors in patients with renal impairment: pre-dialysis, those receiving dialysis or with renal allograft transplants. Materials and methods: Ten patients (nine male, one female) with renal cell tumors were enrolled into a retrospective study; two were new dialysis patients, three on long-term dialysis, and five were renal transplant recipients with history of dialysis. All patients underwent helical CT, a total of 11 procedures were performed. Sixteen-row detector system was used five times, and a 64-row detector system for the six examinations. All patients underwent nephrectomy of kidney with suspected tumor, 15 nephrectomies were performed, and 1 kidney was assessed during autopsy. CT findings were compared with macroscopic and microscopic assessments of the kidney specimen in 16 cases. Results: Very advanced renal parenchyma atrophy with small cysts corresponding to ESRD was found in nine patients, chronic pyelonephritis in remained one. A spontaneously ruptured tumor was detected incidentally in one case, patient died 2 years later. In the present study, 6.25% (1/16) were multiple PRCA, 12.5% (2/16) were solitary PRCC, 12.5% tumors (2/16) were solitary conventional renal cell carcinomas (CRCC's), 12.5% tumors (2/16) were multiple conventional renal cell carcinomas (CRCC's), 25% (4/16) were CRCC's combined with multiple papillary renal cell carcinomas with adenomas (PRCC's and PRCA's), and 25% (4/16) of the tumors were multiple PRCC's combined with PRCA's without coexisting CRCC's. Bilateral renal tumors were found in our study

    Full Text Available Este é um estudo descritivo-exploratório, que objetivou conhecer as concepções, atitudes e comportamentos relacionados ao trabalho, de 16 indivíduos portadores de insuficiência renal crônica (IRC e seus familiares. Os dados foram coletados no período de abril a agosto de 2000, por meio de entrevista semi-estruturada. Os resultados revelaram que o trabalho é valorizado por todas as famílias como fonte de saúde e de provimento financeiro, além de ser importante na formação do caráter do indivíduo; e que a maioria dos indivíduos com IRC não desenvolvem atividade remunerada, e, quando o fazem, contam com a ajuda e compreensão do patrão e familiares. Conclui-se que IRC e seu tratamento não constituem impedimento direto e absoluto à realização desse tipo de atividade, mas trazem limitações importantes. Considera-se necessário os profissionais de saúde se aliarem na busca de apoio por parte de familiares e sociedade, para que esses indivíduos possam ser inseridos no mercado de trabalho quando o desejarem e tiverem condições para tal.Estudio descriptivo y exploratorio que se propuso conocer las concepciones, actitudes, creencias y comportamientos de 16 individuos portadores de insuficiencia renal crónica (IRC y sus familiares, en relación con el trabajo.

    Full Text Available Leptospirosis is an important cause of acute renal failure in our environment. Although several mechanisms are implicated, the role of rhabdomyolysis in the pathogenesis of acute renal failure in leptospirosis has not been analysed. Sixteen patients with the diagnosis of leptospiroses consecutively admitted to the hospital were prospectively studied. The disease was characterized by sudden onset in all patients and, at admission, jaundice, conjunctival suffusion and myalgias. Mild to moderate proteinuria with unremarkable urinary sediment was recorded in 37.5% of the patients and abnormal levels of urea creatinine were found in 87.5% and 74.0%, respectively. Increased levels of aminotranspherase were documented in all 12 and CPK in all 10 patients studied. Serum myoglobin levels greater than 120µg/l recorded in 56.2%. A correlation between myoglobin and renal failure or severity of disease, however, could not be established.Leptospirose é uma importante causa de insuficiência renal aguda, em nosso ambiente. Embora vários sejam os mecanismos implicados, o papel da rabdomiólise na patogênese da insuficiência renal aguda na leptospirose ainda não foi analisado. Com esse objetivo, 16 pacientes com o diagnóstico da forma icterohemorrágica da leptospirose consecutivamente admitidos no Hospital Couto Maia, Salvador, Bahia, foram prospectivamente estudados. A doença foi caracterizada por início súbito e, à admissão, ictericia, sufusões hemorrágicas conjuntivais e mialgias. Proteinúria de intensidade média a moderada com sedimento urinário inexpressivo foi observada em 37,5% dos pacientes e níveis séricos elevados de uréia e creatinina em 78,5% e 74,0%, respectivamente. Níveis aumentados de aminotransferase foram documentados em todos os 12 e de CPK em todos os 10 pacientes avaliados para essas enzimas. Níveis séricos maiores que 120µg/l foram observados em 56,2% dos pacientes. Não foram encontradas correlações, entretanto

    Full Text Available La paracoccidioidomicosis se asocia en 10 a 15% de los casos con insuficiencia suprarrenal e, inclusive, puede ser la primera manifestación de la enfermedad. Para determinar la frecuencia de la anterior relación en nuestro medio, se revisó el archivo de historias clínicas del Servicio de Micología de la Corporación para Investigaciones Biológicas y se encontró que de 207 pacientes con diagnóstico de paracoccidioidomicosis, 6 (2,9% presentaban insuficiencia suprarrenal. Los pacientes eran del sexo masculino con una edad promedio de 67,2 años (rango: 48-75 y la mayoría eran agricultores. El tiempo promedio de duración de los síntomas relacionados con la insuficiencia fue de 4,1 meses (rango: 2-6. Todos los pacientes habían perdido peso, tenían adinamia y, además, radiología pulmonar anormal. El tratamiento con itraconazol, prednisolona y fluorocortisona resultó en mejoría clínica y en disminución de los títulos de anticuerpos contra Paracocidioides brasiliensis. Puesto que se ha demostrado que las alteraciones morfológicas y funcionales de las glándulas suprarrenales pueden desaparecer si se inicia prontamente el tratamiento, sería de vital importancia detectar precozmente el hipoadrenalismo en pacientes provenientes de áreas endémicas para esta micosis y, de tal manera, evitar daños mayores y acortar el tratamiento esteroideo en los pacientes afectados.

    Full Text Available Autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED is a rare autosomal recessive disorder caused by mutations in the autoimmune regulator gene (AIRE. Terminal 4q deletion is also a rare cytogenetic abnormality that causes a variable syndrome of dysmorphic features, mental retardation, growth retardation, and heart and limb defects. We report a 12-year-old Saudi boy with mucocutaneous candidiasis, hypoparathyroidism, and adrenocortical failure consistent with APECED. In addition, he has dysmorphic facial features, growth retardation, and severe global developmental delay. Patient had late development of chronic renal failure. The blastogenesis revealed depressed lymphocytes' response to Candida albicans at 38% when compared to control. Chromosome analysis of the patient revealed 46,XY,del(4(q33. FISH using a 4p/4q subtelomere DNA probe assay confirmed the deletion of qter subtelomere on chromosome 4. Parental chromosomes were normal. The deleted array was further defined using array CGH. AIRE full gene sequencing revealed a homozygous mutation namely 845_846insC. Renal biopsy revealed chronic interstitial nephritis with advanced fibrosis. In addition, there was mesangial deposition of C3, C1q, and IgM. This is, to the best of our knowledge, the first paper showing evidence of autoimmune nephropathy by renal immunofluorescence in a patient with APECED and terminal 4q deletion.

    Arterial hypertension is the most common cardiovascular system disease, affecting nearly one billion people worldwide. Despite the widespread use of antihypertensive medications, in some groups of patients an optimal blood pressure (BP) cannot be achieved. To assess BP reduction in patients with resistant hypertension after a catheter-based renal sympathetic denervation procedure and to report vascular and kidney safety in one-year follow-up. Twenty eight patients with diagnosed resistant hypertension (median age 52.02 years, range 42-72) underwent percutaneous catheter-based renal denervation of nerve terminals in renal arteries. Arterial angiography and procedure of ablation was performed by Symplicity catheters and generator provided by Ardian (currently Medtronic Inc., USA). Mean BP value before ablation was [mm Hg]: systolic 176.6, diastolic 100.28 and pulse pressure 73.4. After the procedure, reductions in the value of BP were reported [mm Hg]: systolic 154.8/152.54; diastolic 90.2/89.8, pulse pressure 64.66/62.73, respectively in nine-month and one-year follow-up. All results were statistically significant. No complications during one year observation were observed. Percutaneous renal artery ablation procedure effectively reduces systolic BP, diastolic BP, and pulse pressure. No vascular or renal complications in any of the patients were observed. The results of a Polish research group showed no significant differences compared to the results obtained in the international studies Symplicity I and Symplicity II.

    Full Text Available La insuficiencia cardíaca es uno de los problemas de salud de mayor relevancia por su incidencia creciente y sus repercusiones sociales, económicas y sobre todo humanas. El trasplante cardíaco es un abordaje excelente y un tratamiento consolidado para estos pacientes. Sin embargo, la desproporción entre el número de pacientes con una insuficiencia cardíaca terminal y los donantes potenciales restringe el trasplante a aquellos pacientes sin otras posibilidades de tratamiento y ha generado alternativas terapéuticas para mejorar el pronóstico y los síntomas de estos pacientes con alto riesgo. El interés creciente del estudio de la reversibilidad de varias formas de insuficiencia cardíaca terminal y la aplicación de la biología al tratamiento de estos pacientes ha inducido el desarrollo de estrategias terapéuticas, diseñadas para integrar la biología y las nuevas tecnologías médicas, para así intervenir sobre los modelos biomecánicos, moleculares y neurohormonales de la insuficiencia cardíaca. Estos tratamientos incluyen la cardiomioplastia celular, la ingeniería tisular, la cirugía de restauración del ventrículo izquierdo, la inmunoadsorción y la constricción mecánica pasiva ventricular como puente a la recuperación. La integración de estos abordajes puede ofrecer alternativas válidas al trasplante cardíaco.

    A 16 year old boy with Noonan syndrome diagnosed in the 3rd month of life was treated for renal insufficiency and hepatic tumor. Hemodialisis was started in preparation for surgery. Exacerbation of renal insufficiency occurred after surgical removal of the hepatic tumor together with the right hepatic lobe. Histopathologic examination showed adenoma hepatocellulare. Cysts in the extraperitoneal space appeared in the following months and were identified as cystes dysontogenetici benigni ''hamartia''. Renal function deteriorated during this time to end stage renal disease. The authors emphasize the possibility of good mental development in a patients with Noonan syndrome as well as the presence of urinary tract abnormalities and renal insufficiency of unknown origin - a phenomenon that has not yet been reported in other cases of Noonan syndrome.

Pesquisa abordando centros especializados mundiais detectou, em 1999, 78 casos em lactentes; destes, em 14% o quadro inicial foi de uremia. A gravidade e a raridade da doença sugerem o relato deste caso.Resultados: criança de sexo feminino, com quadro de vômitos e baixo ganho de peso desde os primeiros meses de vida, desenvolveu insuficiência renal terminal aos 6 meses de idade, sendo mantida em tratamento dialítico desde então. Aos 8 meses, foi encaminhada para esclarecimento diagnóstico, apresentando déficit pôndero-estatural grave e os seguintes exames laboratoriais: uréia= 69 mg/dl, creatinina=2,2 mg/dl e clearance de creatinina= 12,5 ml/min/1.73m²SC. O exame de urina foi normal, a ultra-sonografia renal revelou tamanho normal e hiperecogenicidade de ambos os rins. A dosagem de oxalato urinário foi de 9,2mg/kg/dia ou 0,55 mmol/1.73m²SC, e a relação oxalato:creatinina, de 0,42. A biópsia renal diagnosticou presença de grande quantidade de depósitos de cristais de oxalato de cálcio no parênquima renal. A radiografia de ossos longos evidenciou sinais sugestivos de osteopatia oxalótica, e a fundoscopia indireta, sinais de retinopatia por oxalato.

    Full Text Available El papel del endotelio en la insuficiencia cardíaca (IC ha sido el centro de intensa investigación, puesto que tiene importantes implicaciones sistémicas expresadas en su efecto vasomotor, hemostático e inflamatorio. Existen diferencias individuales en el patrón de la disfunción endotelial de acuerdo a la etiología y severidad de la IC. La disfunción endotelial tiene un importante valor pronóstico en la IC y, aunque aún necesitamos conocer más aspectos de relevancia clínica, es evidente que esta condición se relaciona con desenlaces negativos en estos pacientes. Estamos a la espera de nuevos agentes farmacéuticos dirigidos específicamente al endotelio vascular. En esta revisión, nuestro objetivo es ofrecer un análisis crítico y contemporáneo de la evidencia disponible sobre las consecuencias patológicas y pronóstico de las anomalías endoteliales que definen el inicio, la historia natural y, en última instancia, los desenlaces en la IC.

    Full Text Available Male reproductive function is impaired during end-stage renal disease (ESRD. Disturbance of the hypothalamic-pituitary-gonadal axis, and therefore the regulation of sex hormones, is one of the major causes. Our focus was to include antimüllerian hormone (AMH and inhibin B concentrations. Twenty male patients on hemodialysis, median age 40 (26-48 years, were analyzed for follicle-stimulating hormone (FSH, luteinizing hormone (LH, prolactin, sex hormone-binding globulin (SHBG, testosterone, estradiol, AMH and inhibin B levels. We used 144 proven fertile men, median age 32 (19-44 years as a control group and analyzed differences using multiple linear regression. Males with ESRD demonstrated higher mean values for prolactin, 742 versus normal 210 mIE l−1 (95% confidence interval (CI: 60.3, 729, LH, 8.87 versus normal 4.5 IE l−1 (95% CI: 2.75, 6.14, and estradiol 89.7 versus normal 79.0 pmol l−1 (95% CI: −1.31, −0.15. Mean value for AMH was lower, 19.5 versus normal 47.3 pmol l−1 (95% CI: −37.6, −11.6. There were no differences found for FSH, SHBG, inhibin B and testosterone. The most important difference was found for AMH, a marker of Sertoli cell function in the testes, which decreased by close to 60% when compared with controls. Combined with an increase in LH, these findings may indicate a dysfunction of Sertoli cells and an effect on Leydig cells contributing to a potential mechanism of reproductive dysfunction in men with ESRD.

A 58-year-old man was admitted with complaints of lower limb edema and dyspnea. At admission, nitrogen retention, anemia, hyperkalemia and metabolic acidosis were observed, requiring hemodialysis. The patient had a history of lepromatous leprosy. A renal biopsy was performed that was compatible with amyloidosis. The patient had a stable outcome, but without renal function recovery and remained on regular hemodialysis. Leprosy should be investigated in every patient with renal function loss, particularly in those with cutaneous lesions or other manifestations suggestive of leprosy.

    Secondary hyperparathyroidism unresponsive to medical treatment is a common complication in patients with chronic renal failure and prolonged dialysis therapy, which requires surgery of the parathyroid glands, with the risks and costs of surgery. Objective: To evaluate the therapeutic effectiveness and safety of ablation of parathyroid adenomas by percutaneous ethanol injection under ultrasound guidance. Method: After approval by the institutional medical ethics committee, informed written consent was obtained in 15 patients who met the inclusion criteria. Sonographically guided ethanol was injected consecutively into adenomas, with an interval of time less than six months. Results: Size, Doppler vascularity of adenomas, and the levels of parathyroid hormone, calcium and phosphorus were measured before and after ablation as criteria for treatment response in 15 patients. Of all patients, six (40%) had no therapeutic response. Therapeutic response was observed in nine patients (60%). In the latter group, five patients (33.3%) had successful response and symptomatic improvement, in two patients (13.3%), therapeutic response was suboptimal, and in two patients (13.3%), the response was unsatisfactory. The procedure was safe. Local pain, transient dysphonia and cough were considered minor complications and were the most common, with resolution in all cases. There were no major complications. Conclusion: Ablation of parathyroid adenomas with percutaneous ethanol injection and ultrasound guidance, in uremic patients with secondary hyperparathyroidism unresponsive to medical treatment is an effective and safe therapy. Studies involving more patients and longer follow up are needed in order to stablish more conclusive results

    Full Text Available Introducción: La calcifilaxis se caracteriza por calcificación de arteriolas, fibrosis y trombosis que conduce a la aparición de úlceras cutáneas isquémicas y necrosis, y afecta con mayor frecuencia a pacientes con enfermedad renal crónica terminal. El tratamiento de la calcifilaxis es variado, sin existir una modalidad terapéutica eficaz, y presenta mal pronóstico, principalmente por la sepsis secundaria a infección de las lesiones cutáneas. Objetivo: Conocer la producción científica sobre la calcifilaxis relacionada con la enfermedad renal crónica. Metodología: Se ha llevado a cabo una revisión bibliográfica con una búsqueda de bibliografía en las principales bases de datos PubMed/Medline, Scielo, Cuiden, ProQuest/Health and Medical Complete, IME y Google Académico. Resultados: Se seleccionaron 61 artículos para la realización del estudio: 19 artículos de revisión, 13 originales y 29 casos clínicos. Las variables estudiadas han sido las alteraciones en el metabolismo del fósforo, calcio y hormona paratiroidea, varios factores de riesgo, distribución de las lesiones, fallecimiento por sepsis, tratamiento médico y cuidados de enfermería. Los factores más influyentes en la aparición de calcifilaxis son las alteraciones en el metabolismo, obesidad, diabetes, hipertensión, baja albúmina sérica y toma de anticoagulantes. El tratamiento implica múltiples medidas terapéuticas, dirigidas al control de las alteraciones del metabolismo y la cura de las manifestaciones cutáneas. Conclusiones: La calcifilaxis es una entidad poco frecuente y con una elevada mortalidad. La patogénesis es desconocida y desde el punto de vista terapéutico, no existe un tratamiento específico, por lo que es fundamental un enfoque multidisciplinar, para su prevención y detección precoz.

    Full Text Available La insuficiencia cardíaca constituye una prioridad esencial en el ámbito de la salud, tanto en Norteamérica como en Sud-américa, donde incluso se llega a las hospitalizaciones cuando el diagnóstico principal presenta condiciones graves. Hay una relación directamente proporcional entre prevalencia de insuficiencia cardíaca y edad. Sin embargo, la mortalidad por insuficiencia cardíaca está en declinación debido a los avances médicos, administración de medicamentos, e intervenciones no farmacológicas. Una de estas intervenciones es, el entrenamiento físico o el ejercicio, los cuales están siendo ampliamente aceptados por la comunidad médica como una opción viable en el manejo médico de pacientes con insuficiencia cardíaca permanente. Tanto los ejercicios aeróbicos como de fuerza han demostrado ser eficaces en este tipo de pacientes. Actualmente la evidencia no sólo respalda el ejercicio para mejorar o mantener la función física en pacientes con insuficiencia cardíaca, sino también la calidad de vida en general. Muchos estudios han demostrado que el ejercicio en la población mejora el carácter de las personas y el bienestar general reconocido por ellas mismas. Aunque los beneficios al miocardio producidos por el ejercicio pueden ser mínimos en pacientes con insuficiencia cardíaca, los beneficios periféricos que dan como resultado una mejor capacidad física y la conservación de la independencia son muy significativos. Basados en la evidencia científica existente en el ámbito del ejercicio y la insuficiencia cardíaca, los médicos que trabajan con esta población tienen la información necesaria para recomendar prescripciones de ejercicios. Actualmente, diversas declaraciones de puntos de vista médicos confirman el ejercicio como una modalidad segura y efectiva para pacientes con insuficiencia cardíaca.

    A 16 year old boy with Noonan syndrome diagnosed in the 3rd month of life was treated for renal insufficiency and hepatic tumor. Hemodialisis was started in preparation for surgery. Exacerbation of renal insufficiency occurred after surgical removal of the hepatic tumor together with the right hepatic lobe. Histopathologic examination showed adenoma hepatocellulare. Cysts in the extraperitoneal space appeared in the following months and were identified as cystes dysontogenetici benigni ``hamartia``. Renal function deteriorated during this time to end stage renal disease. The authors emphasize the possibility of good mental development in a patients with Noonan syndrome as well as the presence of urinary tract abnormalities and renal insufficiency of unknown origin - a phenomenon that has not yet been reported in other cases of Noonan syndrome.

    Full Text Available Aproximadamente 1 a 2% de la población adulta tiene insuficiencia cardíaca, llegando a valores sobre el 10% en mayores de 70 años de edad. Una adecuada estrategia en la prevención de la Insuficiencia Cardíaca implica tener un manejo precoz en aquellas etiologías que la producen tales como: hipertensión arterial, enfermedad coronaria, valvulopatías y miocardiopatías. La hipertensión arterial es la primera causa de insuficiencia cardíaca en Chile y se expresa principalmente a través de hipertrofia ventricular izquierda y disfunción diastólica. La enfermedad coronaria genera insuficiencia cardíaca por medio de infarto al miocardio y la isquemia miocárdica sostenida (tejido hibernado, para evitar el compromiso ventricular deben controlarse rigurosamente los factores de riesgo de enfermedad coronaria. En caso de presentarse una obstrucción coronaria aguda se debe reestablecer el flujo coronario a la brevedad para disminuir la necrosis de miocitos. Actualmente las valvulopatías están siendo intervenidas cada vez más precozmente con el fin de evitar la remodelación ventricular patológica irreversible. En relación a las miocardiopatías se debe enfatizar en la necesidad de una detección precoz de la toxicidad por drogas antineoplásicas (ej antraciclinas, del mismo modo debemos preocuparnos de factores emergentes que conducen a insuficiencia cardíaca, ejemplo obesidad.

    Full Text Available Este estudio tiene como objetivo describir comportamientos y capacidad de agencia de autocuidado de pacientes con insuficiencia cardiaca de una clínica cardiovascular de Medellín entre noviembre de 2007 y mayo de 2008. Es un estudio descriptivo con abordaje cuantitativo. La muestra fue de 206 adultos con insuficiencia cardiaca diagnosticados por sintomatología clínica, fracción de eyección menor o igual a 40%. Se usaron para la recolección de datos la Escala Capacidad de Agencia de Autocuidado desarrollada por Isemberg y Evers et ál. (1993, traducida por Gallego, que mide el nivel de agencia de autocuidado, y la Escala Comportamientos de Autocuidado validada en Colombia en 2007 por Arredondo, que mide la frecuencia de comportamientos de autocuidado de adultos con insuficiencia cardiaca en la solicitud de ayuda, adaptación a vivir con la enfermedad y el régimen terapéutico, modificación del autoconcepto y aceptación de sí mismo, vivir con efectos de la insuficiencia cardiaca y el tratamiento. Concluye que el mayor número de pacientes eran hombres; que factores básicos condicionantes como el apoyo de la familia, desempeño de un trabajo, afiliación al sistema de salud, nivel socioeconómico y acceso a un nivel educativo fueron importantes para los pacientes. La frecuencia de comportamientos de autocuidado fue media en los adultos en la mayoría de las dimensiones y el nivel de agencia fue alto y muy alto. Igualmente se concluyó que no hay una correlación entre agencia y comportamientos de autocuidado. Lo que plantea que los adultos tienen el conocimiento pero no han tomado la decisión de realizar acciones de autocuidado.

    among patients with heart failure (HF), body mass index (BMI) has been inversely associated with mortality, giving rise to the so-called obesity paradox. The aim of this study was to examine the relationship between BMI and two modes of cardiac death: pump failure death and sudden death. nine hundred seventy-nine patients with mild to moderate chronic symptomatic HF from the MUSIC (MUerte Subita en Insuficiencia Cardiaca) Study, a prospective, multicenter, and longitudinal study designed to assess risk predictors of cardiac mortality, were followed up during a median of 44 months. Independent predictors of death were identified by a multivariable Cox proportional hazards model. higher BMI emerged as an independent predictor of all-cause mortality (hazard ratio [HR] = 0.94, 95% confidence interval [CI] = 0.91-0.97, P = .0003) and pump failure death (HR = 0.93, 95% CI = 0.88-0.98, P = .004). Sudden death accounted for 45% of deaths in obese patients, 53% in overweight patients, and 37% in lean patients. No significant relationship between BMI and sudden death was observed (HR = 0.97, 95% CI = 0.92-1.02, P = .28). The only independent predictors of sudden death were prior history of myocardial infarction (HR = 1.89, 95% CI = 1.23-2.90, P = .004), hypertension (HR = 1.66, 95% CI = 1.05-2.63, P = .03), left ventricular ejection fraction (HR = 0.88, 95% CI = 0.79-0.96, P = .006), and N-terminal pro-B-type natriuretic peptide (HR = 1.01, 95% CI = 1.00-1.02, P = .048). the obesity paradox in HF affects all-cause mortality and pump failure death but not sudden death. The risk of dying suddenly was similar across BMI categories in this cohort of ambulatory patients with HF.

    Full Text Available La insuficiencia arterial periférica, que en un altísimo porcentaje de casos es secundaria a procesos  degenerativos especialmente arteriosclerosis, es tal vez uno de los hallazgos clínicos más frecuentes en la población adulta de edad avanzada. Sus efectos, que van desde la simple molestia de la isquemia leve en los casos benignos, hasta la necrosis y gangrena de los casos severos, resultan en incapacidad y serias alteraciones funcionales. Bien conocida es la relación que existe entre esta condición y la diabetes y el tabaco. Pero en tanto que la insuficiencia arterial con isquemia de las extremidades inferiores es tan común en los grupos de edad avanzada, es un cuadro muy poco frecuente en individuos jóvenes. En este informe se presentan cinco pacientes jóvenes con cuadros de isquemia severa de las extremidades inferiores con características especiales que los hacen interesantes y motivo de esta discusión.

    Full Text Available La drepanocitosis está asociada con un amplio espectro de alteraciones renales que tienen su base en la falciformación de los eritrocitos en los vasos de la médula renal, que conduce a fenómenos de isquemia, microinfartos y anomalías de la función tubular. Se producen también alteraciones glomerulares funcionales reversibles de la autorregulación renal (hiperfiltración, que pueden conducir a cambios anatómicos irreversibles con glomeruloesclerosis segmentaria focal. Estas anomalías se expresan tempranamente como microalbuminuria, proteinuria y de forma mas tardía, como síndrome nefrótico e insuficiencia renal crónica. Medidas terapéuticas como el uso de inhibidores de la enzima convertidora de la angiotensina II, de los bloqueadores del receptor de la angiotensina II, asociados o no con la hidroxiurea, pueden prevenir o retardar el daño glomerular. En el presente trabajo se exponen de forma resumida aspectos relacionados con la fisiopatología del daño renal en la drepanocitosis y su tratamiento.Sickle cell disease is associated with a wide range of renal disorders resulting from the falciformation of erythrocytes in vessels of the renal medulla, leading to ischemia, microinfarctions and tubular function abnormalities. Reversible glomerular functional renal self-regulation disorders (hyperfiltration also occur, which may lead to irreversible anatomical changes with focal segmental glomerular sclerosis. These anomalies are expressed at an early stage as microalbuminuria and proteinuria, and at a later stage as nephrotic syndrome and chronic renal failure. Therapeutic measures such as the use of angiotensin-II converting enzyme inhibitors and angiotensin-II receptor blockers, associated or not with hydroxyurea, may either prevent or delay glomerular damage. The paper succinctly presents the physiopathology of renal damage in drepanocytosis and its treatment.

    del cisatracúrio, especialmente en los enfermos con insuficiencia orgánica, parece ser benéfica, debido a su eliminación órgano independiente de Hofmann y menor tendencia a liberar histamina. Este trabajo tiene como objetivo determinar, en enfermos portadores de insuficiencia renal crónica, la farmacodinámica del cisatracúrio durante el transplante renal. MÉTODO: Fueron estudiados 30enfermos divididos en dos grupos, 15 con función renal normal sometidos a cirugía bucomaxilo-facial y 15 portadores de insuficiencia renal crónica sometidos a transplante renal bajo anestesia general con etomidato, sufentanil y sevoflurano en concentraciones entre 0,5 y 1% de fracción expirada. Recibieron dosis venosa de 0,15 mg.kg-1 de cisatracúrio en la inducción y 0,05 mg.kg-1 todas las veces que T1 recuperaba 25%. La función neuromuscular fue monitorizada de forma continua por aceleromiografia utilizando el patrón de estimulación secuencia de cuatro estímulos, a través de la estimulación supramáxima del nervio ulnar. RESULTADOS: Los resultados referentes a la farmacodinámica del cisatracúrio muestran que el inicio de acción (4,1 y 4,9 min, la duración clínica (68,9 y 75,4 min y el índice de recuperación (20,2 y 28 min fueron semejantes entre los grupos normal e insuficiencia renal, respectivamente. Los tiempos para la relación T4/T1 llegar a 0,7 (34,3 y 51,4 min y 0,9 (49,7 y 68,6 min a partir del último 25% de T1 presentaron diferencia estadísticamente significante entre los grupos, con los mayores valores en el grupo de insuficiencia renal. La razón de acumulación fue igual a 1,08. CONCLUSIONES: El inicio de acción, la duración clínica y el índice de recuperación son semejantes entre los dos grupos, el tiempo para la relación T4/T1 llegar a 0,7 ó 0,9 fue mayor en el grupo de insuficiencia renal de que en el grupo normal y el cisatracúrio no presentó efecto acumulativo en el grupo de insuficiencia renal.BACKGROUND AND OBJECTIVES

    Renin-angiotensin aldosterone system (RAAS) blockade only partly reduces blood pressure, proteinuria and renal and cardiovascular risk in chronic kidney disease (CKD) but often requires sodium targeting [i.e. low sodium diet (LS) and/or diuretics] for optimal efficacy. However, both under- and overtitration of sodium targeting can easily occur. We evaluated whether N-terminal pro-brain natriuretic peptide (NT-proBNP), a biomarker of volume expansion, predicts the benefits of sodium targeting in CKD patients. In a cross-over randomized controlled trial, 33 non-diabetic CKD patients (proteinuria 3.8 ± 0.4 g/24 h, blood pressure 143/86 ± 3/2 mmHg, creatinine clearance 89 ± 5 mL/min) were treated during 6-week periods with placebo, angiotensin receptor blockade (ARB; losartan 100 mg/day) and ARB plus diuretics (losartan 100 mg/day plus hydrochlorothiazide 25 mg/day), combined with LS (93 ± 52 mmol Na(+)/24 h) and regular sodium diet (RS; 193 ± 62 mmol Na(+)/24 h, P diuretics and was normalized by ARB + diuretic + LS [39 (26-59) pg/mL, P = 0.65 versus controls]. NT-proBNP levels above the upper limit of normal (>125 pg/mL) predicted a larger reduction of blood pressure and proteinuria by LS and diuretics but not by ARB, during all steps of the titration regimen. Elevated NT-proBNP levels predict an enhanced anti-hypertensive and anti-proteinuric benefit of sodium targeting, but not RAAS blockade, in proteinuric CKD patients. Importantly, this applies to the untreated condition, as well as to the subsequent treatment steps, consisting of RAAS blockade and even RAAS blockade combined with diuretics. NT-proBNP can be a useful tool to identify CKD patients in whom sodium targeting can improve blood pressure and proteinuria.

    Full Text Available Chronic renal insufficiency is a functional definition which is characterized by irreversible and progressive decreasing in renal functions. This impairment is in collaboration with glomeruler filtration rate and serum creatinine levels. Besides this, different grades of bone metabolism disorders develop in chronic renal insufficiency. Pathologic changes in bone tissue due to loss of renal paranchyme is interrelated with calcium, phosphorus vitamine-D and parathyroid hormone. Clinically we can see high turnover bone disease, low turnover bone disease, osteomalacia, osteosclerosis and osteoporosis in renal osteodystropy. In this article we aimed to review pathology of bone metabolism disorders due to chronic renal insufficiency, clinic aspects and treatment approaches briefly.

    éticas que se producen en el síndrome de la insuficiencia cardiaca (IC. Aliada a los reflejos cardiovasculares simpatoinhibitorios, suprimidos en el síndrome, la insuficiencia cardiaca puede contribuir a la intolerancia al ejercicio físico. La hiperactivación de los señales originados de los receptores ubicados en los músculos esqueléticos (mecanorreceptores - metaborreceptores es una hipótesis propuesta recientemente para explicar el origen de los síntomas de fatiga y disnea y de los efectos benéficos del entrenamiento físico en el síndrome de IC. En la IC, otras alteraciones en los sistemas de control reflejo, que no son mutuamente exclusivos, contribuyen a la disnea. Estimulación inapropiada de los barorreceptores arteriales, con consecuente falta de inhibición de la descarga del metaborreflejo muscular y quimiorreflejo carotídeo, y el aumento de la vasoconstricción renal con liberación de angiotensina II se pueden también tener en cuenta. A pesar de las alteraciones funcionales de los reflejos haber sido utilizadas de manera independiente para ilustrar la excitación simpática observada en la IC, la interacción entre estos reflejos en condiciones normales y patológicas, especialmente su contribución para el estado simpatoexcitatorio encontrado en la IC, no viene siendo ampliamente estudiada. De este modo, resta todavía un cuestionamiento sobre la posible relación entre los receptores musculares (mecano y metaborreceptores en la génesis de la exacerbación del ergorreflejo observado en la IC. Por tanto, esta revisión tiene por objetivo integrar los conocimientos respecto al mecano y metaborreflejo (ergorreflejo en el síndrome de la insuficiencia cardiaca, así como aclarar la influencia de la terapéutica medicamentosa de la IC en el ergorreflejo.A large body of evidence has suggested the existence of a reflex network that becomes hyperactive secondary to musculoskeletal alterations that occur in heart failure (HF syndrome.

    Full Text Available Recently, the efficacy of renal denervation (RDN has been debated. It is discussed whether RDN is able to adequately target the renal nerves.We aimed to investigate how effective RDN was by means of functional hemodynamic measurements and nerve damage on histology.We performed hemodynamic measurements in both renal arteries of healthy pigs using a Doppler flow and pressure wire. Subsequently unilateral denervation was performed, followed by repeated bilateral hemodynamic measurements. Pigs were terminated directly after RDN or were followed for 3 weeks or 3 months after the procedure. After termination, both treated and control arteries were prepared for histology to evaluate vascular damage and nerve damage. Directly after RDN, resting renal blood flow tended to increase by 29±67% (P = 0.01. In contrast, renal resistance reserve increased from 1.74 (1.28 to 1.88 (1.17 (P = 0.02 during follow-up. Vascular histopathology showed that most nerves around the treated arteries were located outside the lesion areas (8±7 out of 55±25 (14% nerves per pig were observed within a lesion area. Subsequently, a correlation was noted between a more impaired adventitia and a reduction in renal resistance reserve (β: -0.33; P = 0.05 at three weeks of follow-up.Only a small minority of renal nerves was targeted after RDN. Furthermore, more severe adventitial damage was related to a reduction in renal resistance in the treated arteries at follow-up. These hemodynamic and histological observations may indicate that RDN did not sufficiently target the renal nerves. Potentially, this may explain the significant spread in the response after RDN.

Pigs were terminated directly after RDN or were followed for 3 weeks or 3 months after the procedure. After termination, both treated and control arteries were prepared for histology to evaluate vascular damage and nerve damage. Directly after RDN, resting renal blood flow tended to increase by 29±67% (P = 0.01). In contrast, renal resistance reserve increased from 1.74 (1.28) to 1.88 (1.17) (P = 0.02) during follow-up. Vascular histopathology showed that most nerves around the treated arteries were located outside the lesion areas (8±7 out of 55±25 (14%) nerves per pig were observed within a lesion area). Subsequently, a correlation was noted between a more impaired adventitia and a reduction in renal resistance reserve (β: -0.33; P = 0.05) at three weeks of follow-up. Conclusion Only a small minority of renal nerves was targeted after RDN. Furthermore, more severe adventitial damage was related to a reduction in renal resistance in the treated arteries at follow-up. These hemodynamic and histological observations may indicate that RDN did not sufficiently target the renal nerves. Potentially, this may explain the significant spread in the response after RDN.

    Full Text Available Renal cryoablation is an alternative minimally-invasive method of treatment for localized renal cell carcinoma. The main advantages of this methodology include visualization of the tumor and the forming of "ice ball" in real time, fewer complications compared with other methods of treatment of renal cell carcinoma, as well as the possibility of conducting cryotherapy in patients with concomitant pathology. Compared with other ablative technologies cryoablation has a low rate of repeat sessions and good intermediate oncological results. The studies of long-term oncological and functional results of renal cryoablation are presently under way.

    Full Text Available The term adrenal insufficiency refers to the hypofunction of this gland. From the etiologic point of view it may be either primary or secondary. This insufficiency manifests as inadequate serum levels of cortisol and adrenal androgens in the secondary form and of these and mineralocorticoids in the primary one. Clinical manifestations are often nonspecific and, consequently, diagnosis may be difficult to establish and treatment may be delayed with increased morbidity and mortality. This article on adrenal insufficiency includes its definition, epidemiology, etiology, physiopathology, classification, clinical presentation, diagnostic criteria and treatment guidelines. Besides, some special situations like critically ill patients and pregnant women are given special consideration. Emphasis is done on a diagnostic algorithm to make it easier for general practitioners the approach to patients with this endocrine disorder. La insuficiencia adrenal (ia se refiere a la hipofunción de dicha glándula debida a causas tanto primarias como secundarias, que resultan en niveles plasmáticos inadecuados de cortisol, andrógenos adrenales y adicionalmente, en la falla primaria de mineralocorticoides. Sus manifestaciones inespecíficas dificultan o retrasan con frecuencia el diagnóstico y tratamiento oportuno, lo cual incrementa la morbilidad y eventualmente la mortalidad de estos pacientes. Se incluyen en este artículo: definición, epidemiología, causas, fisiopatología, clasificación, manifestaciones clínicas, diagnóstico y tratamiento de la IA. Además se consideran algunas situaciones especiales como la IA en el paciente críticamente enfermo y en la mujer gestante. Finalmente se hace especial énfasis en un algoritmo diagnóstico, con la finalidad de facilitarle al médico general un enfoque ágil y oportuno de los pacientes con este problema endocrino.

    Full Text Available SUMMARYAcute renal failure is a syndrome that usually runs with an increase in creatinine and urea plasma levels. However, there are clinical situations in which this syndrome may run with an increase in plasma creatinine keeping normal the urea one.In this report we present a case of acute renal failure with normal plasma urea level secondary to an acute pyelonephritis in a single kidney patient. The patient had an increased fractional excretion of urea which could explain the normal plasma urea levels found despite of his reduced glomerular filtration. This increased urea excretion state was interpreted as a consequence of the nephrogenic diabetes insipidus and alteration of the intra-renal urea reciclying process that the acute pyelonephritis induced. In conclusion: Acute pyelonephritis in a single kidney patient can appear as a pattern of acute renal failure with normal plasma urea levels. RESUMEN:La insuficiencia renal aguda es un sindrome que característicamente cursa con niveles plasmáticos elevados de urea y creatinina. Sin embargo, hay situaciones clínicas en las cuales este sindrome puede cursar con un incremento de la creatininemia sin presentar elevación de la uremia.En este reporte presentamos un caso clínico de una insuficiencia renal aguda con uremia normal secundaria a una pielonefritis aguda en un paciente con riñón único. El paciente presentaba una elevada excreción fraccional de urea lo cual podía explicar su uremia normal pese a estar cursando una caída del filtrado gomerular. Dicha excreción de urea elevada fue interpretada como secundaria a una diabetes insipida nefrogénica y una alteración en el recirculado intra-renal de la urea ambos producto de la pielonefritis aguda. Concluimos que la pielonefritis aguda en un paciente mono-reno puede presentarse con un patrón de insuficiencia renal aguda con uremia normal.

    Full Text Available La enfermedad renal crónica constituye una patología de prevalencia e impacto creciente en la población mundial por sus múltiples complicaciones, incluyendo un riesgo cardiovascular aumentado, que representa la principal causa de morbimortalidad en pacientes nefrópatas crónicos. Sin embargo, la relevancia de las dislipidemias, especialmente, la hipercolesterolemia LDL, en el deterioro de la función renal y desarrollo de ateroesclerosis en sujetos con daño renal crónico no ha sido claramente establecida. Esta situación ha generado controversia sobre el beneficio real del uso de hipolipemiantes en estos pacientes. En base a la evidencia disponible, incluyendo estudios clínicos recientes, la recomendación más apropiada sugiere que el uso de terapia hipolipemiante basada en estatinas (con o sin ezetimiba es beneficioso desde un punto de vista cardiovascular en nefrópatas crónicos con insuficiencia renal leve a moderada antes de la diálisis. Por otro lado, no existe evidencia definitiva para apoyar el uso rutinario de este tipo de hipolipemiantes en el manejo del deterioro de la filtración glomerular y/o la proteinuria. Basándose en la evidencia analizada en esta revisión, las futuras guías clínicas para el manejo del daño renal crónico deberán incorporar el uso de estatinas y/o ezetimiba como un elemento más dentro del armamento terapéutico de este tipo de pacientes.

Además, existen trastornos de funciones cognitivas omnipresentes en pacientes con insuficiencia cardiaca. Se obser - van deficiencias de distinto nivel de severidad en varios dominios cognitivos. Asimismo, en la depresión existen problemas cognitivos que podrían perjudicar el funcionamiento cotidiano, obstaculizar la adaptación a la enfermedad y empeorar los pronósticos. El objetivo de este trabajo fue evaluar la relación entre calidad de vida, intensificación de trastornos depresivos y trastornos de ciertos aspectos de las funciones ejecutivas y me - moria en pacientes con insuficiencia cardiaca grave y estable. Método : Los estudios se realizaron en un grupo de 50 pacientes con insuficiencia cardiaca grave y estable, y otro de 50 pacientes con enfermedad coronaria, pero sin insuficiencia cardiaca. Resultados : Los resultados de las pruebas cognitivas son notablemente peores en el grupo con insufi - ciencia cardiaca en comparación con el grupo control. Se observó una calidad de vida considerablemente peor y unos resultados significativamente más altos en la prueba BDI- II. No se demostró que los trastornos cognitivos influyeran en el empeoramiento de la calidad de vida. Sin embargo, se observó que los síntomas de depresión influían en la calidad de vida. Conclusiones : El factor que afecta significativamente la calidad de vida es la intensificación de los síntomas depresivos.

Los problemas derivados de ella, son una causa importante de gasto económico y absentismo laboral. Las condiciones laborales actuales, como jornadas de larga duración, con largas horas en bipedestación, inadecuada carga de pesos y malas condiciones de humedad y temperatura, contribuyen al desarrollo de esta patología. En este trabajo se ha realizado una revisión sistemática de la bibliografía existente en relación a la insuficiencia venosa crónica y el tiempo en bipedestación de las jornadas laborales. Para determinar el nivel de evidencia de los estudios evaluados, se han seguido los criterios del Scottish Intercollegiate Guidelines Network (SIGN. En particular, se ha concluido que existe una asociación significativamente positiva entre el tiempo prolongado en bipedestación y el riesgo de padecer insuficiencia venosa crónica. Sin embargo, la literatura actual no permite establecer un umbral que determine el número de horas considerado como bipedestación prolongada. Para poder valorar si la insuficiencia venosa crónica debería considerarse una enfermedad profesional, es necesario diseñar y llevar a cabo nuevos estudios de investigación en esta dirección. Estos estudios son necesarios para poder establecer evidencias de cara a concienciar a la sociedad y generar campañas de prevención y promoción de la salud que disminuyan los costes económicos y mejoren la calidad de vida de la población.

    Full Text Available INTRODUCTION: Renal hemangioma is a relatively rare benign tumor, seldom diagnosed as a cause of hematuria. CASE REPORT: A female 40-year old patient presented with continuous gross hematuria, anemia and episodic right lumbar pain, with onset about 3 months previously. The patient underwent multiple blood transfusions during her hospital stay and extensive imaging propedeutics was performed. Semi-rigid ureterorenoscopy evidenced a bleeding focus in the upper calix of the right kidney, with endoscopic treatment being unfeasible. The patient underwent right upper pole nephrectomy and presented a favorable outcome. Histopathological analysis of the surgical specimen showed that it was a renal hemangioma. COMMENTS: Imaging methods usually employed for diagnostic investigation of hematuria do not have good sensitivity for renal hemangioma. However, they are important to exclude the most frequent differential diagnoses. The ureterorenoscopy is the diagnostic method of choice and endoscopic treatment can be feasible when the lesion is accessible and electrocautery or laser are available. We emphasize the open surgical treatment as a therapeutic option upon failure of less invasive methods.

    Angiographies on forty cases of renal tuberculosis performed at the National Medical Center during a period 1960 through 1970 were reviewed. Abdominal angiography was performed via the femoral route. Some were followed by selective nephroangiography. All patients were subjected to urographyior to angiography. The results of X-ray findings in the forty cases with renal tuberculosis were follows. 1. The age varied 18 to 57 years, average 30.5 years. Twenty one patients were male, and nineteen were female. 2. The right kidney was involved in 17 cases and the left in 15 cases. Both kidneys were involved in 8 cases. 3. Urographic examination revealed pathologic changes in all patients. 4. Focal destruction in the collecting system was the most common finding in the urography of 16 patients. 5. A varying degree of hydronephrosis was present in 15 patients, of whom nine had complained of palpable mass due to hydronephrosis. 6. In the 7 patients with extensive destruction there was no observable excretion contrast medium from the diseased kidney. 7. Angiographic examination was normal in 6 of the 40 patients. 8. Decreased vascularity in the subsegmental or smaller arteries of the affected kidney was the most frequent finding, being found in 34 patients. 9. Occlusion or abrupt termination of the subsegmental arteries was present in 4 patients. 10. Eighteen of the patients had signs of an expansive process within the cavity, the vessels being displaced and stretched around the lesions.

    Full Text Available Las manifestaciones cardiovasculares del hipertiroidismo son frecuentes, y en ocasiones dominan el cuadro clínico. Con frecuencia, la enfermedad se manifiesta por un estado circulatorio hiperdinámico, con disminución de la resistencia vascular periférica, aumento de la volemia y del volumen minuto cardíaco. La dilatación de las cavidades cardíacas con insuficiencia tricuspídea grave e insuficiencia cardíaca derecha sin hipertensión pulmonar constituye una forma inusual de presentación. Se presenta el caso de una joven paciente, portadora de enfermedad de Graves Basedow, sin antecedentes cardiovasculares, que evoluciona en el transcurso de un mes con edema de miembros inferiores, palpitaciones, diarrea, pérdida de peso y fiebre. Al examen clínico se evidencian taquicardia con pulso irregular, signos de insuficiencia cardíaca derecha acompañado de un intenso soplo regurgitante que aumentaba con la inspiración. Por radiografía de tórax y ecocardiograma se constata cardiomegalia e insuficiencia tricuspídea grave sin hipertensión pulmonar. El cuadro se resuelve en forma rápida luego del tratamiento con propranolol, corticoides y diuréticos, con reversión de la arritmia y franca mejoría de los signos y síntomas. Se analizan en forma breve los efectos de las hormonas tiroideas en el aparato cardiovascular y se postulan probables mecanismos fisiopatológicos de la insuficiencia cardíaca en el hipertiroidismo.Cardiovascular manifestations of hyperthyroidism are frequent and sometimes are relevant in the clinical picture.

    Full Text Available Tuberculosis is still a significant health problem in the world, mostly in developing countries. The special significance lies in immunocompromised patients, particularly those suffering from the HIV. Urogenital tuberculosis is one of the most common forms of extrapulmonary tuberculosis, while the most commonly involved organ is the kidney. Renal tuberculosis occurs by hematogenous dissemination of mycobacterium tuberculosis from a primary tuberculosis foci in the body. Tuberculosis is characterized by the formation of pathognomonic lesions in the tissues - granulomata. These granulomata may heal spontaneously or remain stable for years. In certain circumstances in the body associated with immunosuppression, the disease may be activated. Central caseous necrosis occurs within tuberculoma, leading to formation of cavities that destroy renal parenchyma. The process may gain access to the collecting system, forming the caverns. In this way, infection can be spread distally to renal pelvis, ureter and bladder. Scaring of tissue by tuberculosis process may lead to development of strictures of the urinary tract. The clinical manifestations are presented by nonspecific symptoms and signs, so tuberculosis can often be overlooked. Sterile pyuria is characteristic for urinary tuberculosis. Dysuric complaints, flank pain or hematuria may be presented in patients. Constitutional symptoms of fever, weight loss and night sweats are presented in some severe cases. Diagnosis is made by isolation of mycobacterium tuberculosis in urine samples, by cultures carried out on standard solid media optimized for mycobacterial growth. Different imaging studies are used in diagnostics - IVU, CT and NMR are the most important. Medical therapy is the main modality of tuberculosis treatment. The first line anti-tuberculosis drugs include isoniazid, rifampicin, pyrazinamide and ethambutol. Surgical treatment is required in some cases, to remove severely damaged kidney, if

    Full Text Available Cystinosis is an autosomal recessive, lysosomal storage disease characterised by the accumulation of the amino acid cystine in different organs and tissues. It is a multisystemic disease that can present with renal and extra-renal manifestations. In this report, we present the first case of transplanted nephropathic cystinosis in a Tunisian child. A 4-year-old Tunisian boy born to nonconsanguineous parents, was treated in our medical services in 1990 for cystinosis. Since the age of five months, he developed symptoms of severe weight loss, vomiting, dehydration, and polyuria. He manifested the Toni Debré Fanconi syndrome. Slit lamp examination of the anterior segment of both eyes revealed fine, shiny crystal-like deposits diffusely distributed in the corneal epithelium and the stroma. Our patient had renal failure. At the age of seven, he reached terminal chronic renal failure and was treated with peritoneal dialysis. Hemodialysis was started at the age of nine years. At the age of 13 years, he received a renal transplantation and was started on cysteamine 1999, five months after the renal transplantation. Currently, the patient is 28-year-old. The graft has survived 15 years after the transplantation. Renal functions were stable with a serum creatinine of 123 μmol/L at last follow-up.

    Stone in the urinary tract has fascinated the medical profession from the earliest times and has played an important part in the development of surgery. The earliest major planned operations were for the removal of vesical calculus; renal and ureteric calculi provided the first stimulus for the radiological investigation of the viscera, and the biochemical investigation of the causes of calculus formation has been the training ground for surgeons interested in metabolic disorders. It is therefore no surprise that stone has been the subject of a number of monographs by eminent urologists, but the rapid development of knowledge has made it possible for each one of these authors to produce something new. There is still a technical challenge to the surgeon in the removal of renal calculi, and on this topic we are always glad to have the advice of a master craftsman; but inevitably much of the interest centres on the elucidation of the causes of stone formation and its prevention. Professor Pyrah has had a long an...

    The effect of prolonged hypotensive anesthesia and surgery on renal function was studied in 8 dogs with decreased renal mass. Renal mass was reduced by unilateral nephrectomy and ligation of 4 of the 6 terminal renal artery branches of the opposite kidney. One week after reduction in renal mass, the dogs were azotemic with a serum urea nitrogen (SUN) value of 65.8 +/- 11.5 mg/dl. Glomerular filtration rate, as estimated by 14C-inulin clearance, was 0.66 +/- 0.19 ml/kg of body weight/hour. A mean arterial pressure of less than 75 mm of Hg was maintained for 4 hours in dogs given 2.3 +/- 0.7% halothane. An exploratory laparotomy lasting 1 hour was performed. The day after the hypotensive episode, 3 dogs began vomiting, became dehydrated, and had SUN values greater than 100 mg/dl. The SUN values returned to base-line values after the dogs were rehydrated. Eight days after the hypotensive episode, 14C-inulin clearance decreased 15.2 +/- 8.2% (P less than 0.005) compared with base-line clearance values. Light microscopic and electron microscopic observations of the kidneys did not demonstrate acute renal failure. Prolonged hypotensive anesthesia can cause a decrease in renal function, and may cause prerenal uremia and/or acute renal failure.

    Pregnancy in women with chronic renal failure is a complex therapeutic problem requiring a multidisciplinary approach. It is associated with a higher risk of many perinatal complications. The most common abnormalities are related to: progression of renal failure, development of preeclampsia development of nephrotic syndrome, anemic syndrome, IUGR and fetal death. The prognosis depends on the values of serum creatinine prior to pregnancy, the degree of deterioration of renal function, development of additional obstetric complications and the specific etiological reasons that have led to the occurrence of renal failure. Determining the optimum time for authorization birth depends on the condition of the mother, the condition of the fetus and the rate of progression of renal failure, and the deadline the pregnancy should be terminated is 35 weeks. We present a case of a patient with chronic renal failure, with favorable perinatal outcome.

    Radionuclide renal imaging and plasma clearance methods can quickly quantitate renal blood flow and function in renal transplants. They can diagnose acute tubular necrosis and rejection, renal scar, surgical complications such as urine leaks, obstruction and renal artery stenosis after renal transplants. At the same time they can assess the therapy effect of renal transplant complications and can also predict renal transplant survival from early post-operative function studies

  5. CONTAINER TERMINALS IN EUROPE

    Directory of Open Access Journals (Sweden)

    Bart W. WIEGMANS

    2001-01-01

    Full Text Available This paper aims to address the linkage between logistics (in particular, the management of marketing channel flows and transport markets, while also the interaction between these two markets and intermodal container terminals is analysed. The marketing channel theory is used to describe all relevant actors and flows that run through marketing channels, starting with customer needs and ending with customer satisfaction. Porter's theory of competitive advantages is used to review competitive forces in both markets. Finally, a competitor analysis is performed for the logistics and transport market. These theories are applied so as to be able to determine the competitive position of intermodal container terminals with a view to the management of marketing channel flows and the physical transport of freight flows. Hence, the central question of this paper is: Which markets are served by intermodal container terminals and with whom are they competing? At present, neither the maritime container terminals nor the continental container terminals appear to have a significant influence in the logistics service market; they concentrate mainly on the physical movement of containers (transshipment. Furthermore, maritime container terminals and continental container terminals are not dominant players in the transport service market. Our conclusion is that continental terminals are predominantly competing with unimodal road transport, with neighbouring continental terminals and with barge transport companies.

    Recently, ultrasound-guided percutaneous renal biopsy has been used in the diagnosis of renal diseases. Development of an arteriovenous fistula (AVF), which is one of the post-biopsy complications, is not frequently encountered. AVFs are usually asymptomatic; however, they may lead to serious outcomes. We report a 21-year-old patient, who had been on dialysis for 5 years. Due to high blood pressure (230/160 mmHg) and a thrill in the lumbar area detected on physical examination, Doppler examination was performed and a renal AVF was detected. Because the patient had a history of renal biopsy 5 years previously, the fistula was thought to be secondary to the biopsy. After embolization of the AVF, renal functions improved enough to terminate dialysis treatment.

    Four cases of traumatic renal artery occlusion were described and illustrated. In two cases, direct blows to the abdomen compressed the renal artery against the vertebral column. Clinically, they were severely injured with macroscopic hematuria. Aortograms showed abrupt truncation of renal arteries. In the other two, rapid deceleration caused sudden displacement of the kidney producing an intimal tear with resultant thrombosis. Although they showed little injury without macrohematuria, aortograms revealed tapered occlusion of renal arteries. One of them developed hypertension. ''Rim sign'' of post-contrast CT and hypertension resulted from traumatic renal artery occlusion were reviewed. (author)

    Kitimat Liquefied Natural Gas (LNG) terminal is a terminal development company owned by Galveston LNG, a privately owned Canadian energy development company. This presentation provided information on Kitimat LNG with particular reference to its terminal located in Bish Cove on the Douglas Channel in British Columbia. This LNG terminal is reported to be the only fully permitted regasification terminal on the west coast of Canada and the United States. The presentation addressed market fundamentals including several graphs, such as world natural gas proved reserves in 2006; LNG supplements to Canadian gas supplies; global LNG demand for 2005-2020; average annual United States LNG imports; and global LNG liquefaction projects. Other market fundamentals were described, including that Kitimat is the only other approved terminal aside from the Costa Azul terminal in Mexico; Kitimat is the only west coast LNG import terminal that connects to midwest and eastern North American markets through existing gas pipelines; LNG producers are looking for destination diversification; and markets and marketers are looking for supply diversification. The authors noted that by 2010, western Canadian gas demand will exceed Californian demand. Other topics that were discussed in the presentation included Canadian natural gas field receipts; unadjusted bitumen production outlook; oil sands gas demand; forward basis fundamentals; and the commercial drivers of the Kitimat LNG terminal. The presentation also discussed the pacific trail pipelines, a partnership between Galveston LNG and Pacific Northern Gas to develop the natural gas transmission line from Kitimat to Summit. The presentation concluded with a discussion of the benefits of Kitimat LNG terminal such as providing access to the largest natural gas markets in the world via major gas transmission lines with spare capacity. figs

    Full Text Available En los últimos años, dados los excelentes resultados obtenidos fundamentalmente con la reparación quirúrgica de la válvula mitral, en la insuficiencia mitral de origen degenerativo (tipo II de Carpentier, existe una tendencia creciente de indicar la cirugía de forma precoz. Algunos autores proponen incluir aquí a los pacientes todavía asintomáticos, sin ningún deterioro anatómico ni hemodinámico generado por esta enfermedad. Es propósito de esta revisión analizar cada uno de los determinantes pronósticos principales ya conocidos, así como alguno todavía no suficientemente considerado, como el monto de la regurgitación mitral grave medido ecocardiográficamente y ponderado como volumen regurgitante y/o como área del orificio de regurgitación efectiva. También se estima el valor de la medición de los péptidos natriuréticos tanto atrial como cerebral, y su correlación con el incremento observado a medida que aumenta el grado de insuficiencia valvular y su repercusión clínica y hemodinámica. Se hace hincapié en el valor aditivo de más de una variable en forma combinada con otra para valorar con mayor precisión el riesgo y pronóstico de la enfermedad.

    pacientes internados por descompensación de la insuficiencia cardiaca y con empleo por más de 15 días de dobutamina, o una o más intentos sin éxito de retirada; dosis optimizada de IECA; y FEVI BACKGROUND: During heart failure (HF decompensation, an intense activation of the renin-angiotensin-aldosterone system occurs; however, the use of angiotensin-converting enzyme inhibitor (ACEI cannot block it completely. Otherwise, the addition of angiotensin II receptor blocker (ARB can be useful when the inotropic dependence occurs. We evaluated the efficacy of the ARB-ACEI association on dobutamine withdrawal in advanced decompensated HF. OBJECTIVE: To assess the efficacy of association angiotensin receptor blocker - angiotensin converting enzyme inhibitor to withdraw the intravenous inotropic support in decompensated severe heart failure. METHODS: In a case-control study (N = 24, we selected patients admitted at the hospital due to HF that had been using dobutamine for more than 15 days, with one or more unsuccessful drug withdrawal attempts; optimized dose of ACEI and ejection fraction (EF < 0.45. Then, the patients additionally received ARB (n=12 or not (control, n=12. The outcome was the successful dobutamine withdrawal, evaluated by logistic regression, with a p < 0.05. RESULTS: The EF was 0.25 and the age was 53 years, with a dobutamine dose of 10.7 μg/kg.min. The successful drug withdrawal was observed in 8 patients from the ARB group (67.7% and in 2 patients from the control group (16.7%. The odds ratio (OR was 10.0 (95%CI: 1.4 to 69.3; p = 0.02. The worsening in renal function was similar (ARB group: 42% vs. control group: 67%; p=0.129. CONCLUSION: In this pilot study, the ARB-ACEI association was associated with successful dobutamine withdrawal in advanced decompensated heart failure. The worsening in renal function was similar in both groups. Further studies are necessary to clarify the issue.

    2003-05-01

    Chronic renal insufficiency, hemodialysis, peritoneal dialysis, renal transplantation and administration of different medications provoke complex biochemical disturbances of the calcium-phosphate metabolism with wide spectrum of bone and soft tissue abnormalities termed renal osteodystrophy. Clinically most important manifestation of renal bone disease includes secondary hyperparathyroidism, osteomalacia/rickets, osteoporosis, adynamic bone disease and soft tissue calcification. As a complication of long-term hemodialysis and renal transplantation amyloid deposition, destructive spondyloarthropathy, osteonecrosis, and musculoskeletal infections may occur. Due to more sophisticated diagnostic methods and more efficient treatment classical radiographic features of secondary hyperparathyroidism and osteomalacia/rickets are now less frequently seen. Radiological investigations play an important role in early diagnosis and follow-up of the renal bone disease. Although numerous new imaging modalities have been introduced in clinical practice (scintigraphy, CT, MRI, quantitative imaging), plain film radiography, especially fine quality hand radiograph, still represents most widely used examination.

    Full Text Available Abstract Background There is still confusion and controversy over the diagnosis and optimal surgical treatment of non traumatic terminal ileal perforation-a cause of obscure peritonitis. Methods This study was a prospective study aimed at evaluating the clinical profile, etiology and optimal surgical management of patients with nontraumatic terminal ileal perforation. Results There were 79 cases of nontraumatic terminal ileal perforation; the causes for perforation were enteric fever(62%, nonspecific inflammation(26%, obstruction(6%, tuberculosis(4% and radiation enteritis (1%. Simple closure of the perforation (49% and end to side ileotransverse anastomosis(42% were the mainstay of the surgical management. Conclusion Terminal ileal perforation should be suspected in all cases of peritonitis especially in developing countries and surgical treatment should be optimized taking various accounts like etiology, delay in surgery and operative findings into consideration to reduce the incidence of deadly complications like fecal fistula.

    Renal artery disease is a potentially correctable cause of hypertension. Previous studies have suggested the utility of duplex sonography in accurately detecting and grading the severity of renal artery stenosis. The purpose of this paper is to evaluate color flow Doppler for this use. Forty-three kidneys were examined by color-flow Doppler and conventional duplex sampling in patients with suspected renovascular hypertension or those undergoing aortography for unrelated reasons. Doppler tracings were obtained from the renal arteries and aorta with calculation of the renal aortic ratio (RAR) and resistive index (RI). Results of Doppler sampling with color flow guidance were compared with aortograms in a blinded fashion

    Full Text Available Primary renal cell carcinomas have rarely been reported in patients with crossed fused renal ectopia. We presented a patient with right to left crossed fused kidney harbouring renal tumor. The most frequent tumor encountered in crossed fused renal ectopia is renal cell carcinoma. In this case, partial nephrectomy was performed which pave way to preservation of the uninvolved both renal units. Due to unpredictable anatomy, careful preoperative planning and meticulous delineation of renal vasculature is essential for preservation of the uninvolved renal units.

    Knowledge of the variations of the renal artery has grown in importance with increasing numbers of renal transplants, vascular reconstructions and various surgical and radio logic techniques being performed in recent years. We report the presence of bilateral triple renal arteries, discovered on routine dissection of a male cadaver. On the right side, one additional renal artery originated from the abdominal aorta (distributed to superior pole of the kidney) and one other originated from the right common iliac artery (distributed to lower pole of the kidney). On the left side, both additional renal arteries originated from the abdominal aorta. Our observation has been compared with variations described in the literature and their clinical importance has been emphasized. (author)

    Renal mechanisms, in particular the renin-angiotensin system and renal salt handling, are of major importance in blood pressure regulation. Co-existence of hypertension and decreased renal function may be due to nephrosclerosis secondary to hypertension, or primary renal disease with secondary...... hypertension.

    Windows Terminal Servers provide application gateways for various parts of the CERN accelerator complex, used by hundreds of CERN users every day. The combination of new tools such as Puppet, HAProxy and Microsoft System Center suite enable automation of provisioning workflows to provide a terminal server infrastructure that can scale up and down in an automated manner. The orchestration does not only reduce the time and effort necessary to deploy new instances, but also facilitates operations such as patching, analysis and recreation of compromised nodes as well as catering for workload peaks.

    Full Text Available IntroducciónLa insuficiencia cardíaca (IC es un problema de salud de creciente importancia, especialmente entre los pacientes añosos. Sobre la base de la función sistólica del ventrículo izquierdo (FSVI, existen dos tipos de insuficiencia cardíaca (IC con FSVI deteriorada e IC con FSVI conservada que se caracterizan por tener diferencias fisiopatológicas y clínicas. Nuestra hipótesis es que esto podría devenir en una diferente utilización de los recursos de la salud.Pese a su importancia, no existen en la Argentina registros que comparen los costos hospitalarios de estas dos formas de IC en pacientes añosos, población en la que predomina la IC con FSVI conservada (fracción de eyección ≥ 50%.ObjetivoAnalizar los costos hospitalarios de estas dos formas de IC en pacientes añosos.Material y métodosSe analizaron datos de 133 pacientes añosos internados por IC. La muestra se dividió según la FSVI; se compararon las características previas y durante la hospitalización y los costos totales desde la perspectiva del financiador.ResultadosLa IC con FSVI conservada fue más frecuente (55,6% y con predominio femenino. No se observaron grandes diferencias entre ambos grupos, excepto para el uso de espironolactona y la cantidad de medicaciones recibidas, que fue más frecuente en el grupo con FSVI deteriorada.Esta última presentó un costo total mayor (27% más respecto de la otra variante, mayor tiempo de internación y un costo de medicamentos más elevado.ConclusionesSi bien el número de pacientes es reducido, el presente trabajo brinda una aproximación acerca de la importancia del análisis de costos de ambas formas de IC en sujetos añosos en la Argentina, lo cual constituye el paso inicial para la proyección de los gastos en salud.

  4. Renal imaging in paediatrics

    The most frequent renal diseases in paediatrics include urinary tract infections, hydronephrosis, kidney anomalies and reflux. The main reason for performing DMSA scintigraphy in paediatrics is the detection of cortical abnormalities related to urinary tract infection. Because the amount of tracer retained in the tubular cells is associated with the distribution of functioning renal parenchyma in the kidney, it is possible, to evaluate the split renal function. In comparison to ultrasound and intravenous urography the sensitivity in the detection of acute as well as chronic inflammatory changes is very high, however less specific. An indication for a renography in neonates and children is beside an estimation of the total renal function and the calculation of the split renal function, the assessment of renal drainage in patients with unclear dilatation of the collecting system in ultrasound. The analysis of the time activity curve provides, especially for follow-up studies, a reproducible method to assess the urinary outflow. The diuretic scintigraphy allows the detection of urinary obstruction. Subsequently it is possible to image the micturition phase to detect vesico-ureteric reflux (indirect MCU) after drainage of tracer from the renal pelvis. An reflux in the ureters or the pelvicalyceal system is visible on the scintigraphic images and can be confirmed by time activity curves. A more invasive technique is the direct isotope cystography with bladder catheterization. The present paper should give an overview about the role of nuclear medicine in paediatric urology. (orig.)

    PURPOSE OF REVIEW: Recent biochemical evidence increasingly implicates inflammatory mechanisms as precipitants of acute renal failure. In this review, we detail some of these pathways together with potential new therapeutic targets. RECENT FINDINGS: Neutrophil gelatinase-associated lipocalin appears to be a sensitive, specific and reliable biomarker of renal injury, which may be predictive of renal outcome in the perioperative setting. For estimation of glomerular filtration rate, cystatin C is superior to creatinine. No drug is definitively effective at preventing postoperative renal failure. Clinical trials of fenoldopam and atrial natriuretic peptide are, at best, equivocal. As with pharmacological preconditioning of the heart, volatile anaesthetic agents appear to offer a protective effect to the subsequently ischaemic kidney. SUMMARY: Although a greatly improved understanding of the pathophysiology of acute renal failure has offered even more therapeutic targets, the maintenance of intravascular euvolaemia and perfusion pressure is most effective at preventing new postoperative acute renal failure. In the future, strategies targeting renal regeneration after injury will use bone marrow-derived stem cells and growth factors such as insulin-like growth factor-1.

  8. Trauma and termination.

    Science.gov (United States)

    Ferraro, F

    1995-02-01

    The author suggests a particular reading of the thesis put forward by Freud in 'Analysis terminable and interminable' that an effective and more definitive conclusion may be expected in analyses of cases with traumatic aetiology. This reading shifts the emphasis from the patient's history to the possibility of its crystallising in focal nuclei emerging within the analytic relationship under the pressure of the termination. The revival of separation anxieties which cannot be worked through, and their crystallisation in precipitating traumatic events, may give rise to decisive psychic work allowing the analysis to be brought to a conclusion. Two case histories are presented to show how the end of the analysis assumes the form of a new trauma, which reactivates in the present, traumatic anxieties from the patient's own infantile history. In the first case a premature birth and in the second a miscarriage, originally experienced as isolated automatic events without time or history, are relived in the terminal phase as vicissitudes of the transference, so that new meaning can be assigned to them and they can be withdrawn from the somatic cycle of repetition. The powerful tendency to act out and the intense countertransference pressure on the analyst are discussed in the light of the specificities of this phase, which is crucial to the success of the analysis. This leads to a re-examination, in the concluding notes, of some theoretical questions inherent in the problem of the termination and, in particular, to a discussion of the ambiguous concept of a natural ending.

  9. Prematurely terminated slug tests

    International Nuclear Information System (INIS)

    Karasaki, K.

    1990-07-01

    A solution of the well response to a prematurely terminated slug test (PTST) is presented. The advantages of a PTST over conventional slug tests are discussed. A systematized procedure of a PTST is proposed, where a slug test is terminated in the midpoint of the flow point, and the subsequent shut-in data is recorded and analyzed. This method requires a downhole shut-in device and a pressure transducer, which is no more than the conventional deep-well slug testing. As opposed to slug tests, which are ineffective when a skin is present, more accurate estimate of formation permeability can be made using a PTST. Premature termination also shortens the test duration considerably. Because in most cases no more information is gained by completing a slug test to the end, the author recommends that conventional slug tests be replaced by the premature termination technique. This study is part of an investigation of the feasibility of geologic isolation of nuclear wastes being carried out by the US Department of Energy and the National Cooperative for the Storage of Radioactive Waste of Switzerland

    2005-01-01

    Background: Rates of renal cancer have increased steadily during the past two decades, and these increases are not explicable solely by advances in imaging modalities. Cadmium, a widespread environmental pollutant, is a carcinogen that accumulates in the kidney cortex and is a cause of end-stage renal disease. Several observations suggest that cadmium may be a cause of renal cancer. Methods: We performed a systematic review of the literature on cadmium and renal cancer using MEDLINE for the years 1966-2003. We reviewed seven epidemiological and eleven clinical studies. Results: Despite different methodologies, three large epidemiologic studies indicate that occupational exposure to cadmium is associated with increased risk renal cancer, with odds ratios varying from 1.2 to 5.0. Six of seven studies that compared the cadmium content of kidneys from patients with kidney cancer to that of patients without kidney cancer found lower concentrations of cadmium in renal cancer tissues. Conclusions: Exposure to cadmium appears to be associated with renal cancer, although this conclusion is tempered by the inability of studies to assess cumulative cadmium exposure from all sources including smoking and diet. The paradoxical findings of lower cadmium content in kidney tissues from patients with renal cancer may be caused by dilution of cadmium in rapidly dividing cells. This and other methodological problems limit the interpretation of studies of cadmium in clinical samples. Whether cadmium is a cause of renal cancer may be answered more definitively by future studies that employ biomarkers of cadmium exposure, such as cadmium levels in blood and urine

    The National Oceanic and Atmospheric Administration (NOAA), Department of Defense (DoD), and National Aeronautics and Space Administration (NASA) are jointly acquiring the next-generation weather and environmental satellite system; the National Polar-orbiting Operational Environmental Satellite System (NPOESS). NPOESS replaces the current Polar-orbiting Operational Environmental Satellites (POES) managed by NOAA and the Defense Meteorological Satellite Program (DMSP) managed by the DoD. The NPOESS satellites carry a suite of sensors that collect meteorological, oceanographic, climatological, and solar-geophysical observations of the earth, atmosphere, and space. The ground data processing segment for NPOESS is the Interface Data Processing Segment (IDPS), developed by Raytheon Intelligence and Information Systems. The IDPS processes NPOESS satellite data to provide environmental data products (aka, Environmental Data Records or EDRs) to NOAA and DoD processing centers operated by the United States government. The IDPS will process EDRs beginning with the NPOESS Preparatory Project (NPP) and continuing through the lifetime of the NPOESS system. IDPS also provides the software and requirements for the Field Terminal Segment (FTS). NPOESS provides support to deployed field terminals by providing mission data in the Low Rate and High Rate downlinks (LRD/HRD), mission support data needed to generate EDRs and decryption keys needed to decrypt mission data during Selective data Encryption (SDE). Mission support data consists of globally relevant data, geographically constrained data, and two line element sets. NPOESS provides these mission support data via the Internet accessible Mission Support Data Server and HRD/LRD downlinks. This presentation will illustrate and describe the NPOESS capabilities in support of Field Terminal users. This discussion will include the mission support data available to Field Terminal users, content of the direct broadcast HRD and LRD

    Atherosclerotic renal artery stenosis (RAS) is the single largest cause of secondary hypertension; it is associated with progressive renal insufficiency and causes cardiovascular complications such as refractory heart failure and flash pulmonary edema. Medical therapy, including risk factor modification, renin-angiotensin-aldosterone system antagonists, lipid-lowering agents, and antiplatelet therapy, is advised in all patients. Patients with uncontrolled renovascular hypertension despite optimal medical therapy, ischemic nephropathy, and cardiac destabilization syndromes who have severe RAS are likely to benefit from renal artery revascularization. Screening for RAS can be done with Doppler ultrasonography, CT angiography, and magnetic resonance angiography. Copyright © 2015 Elsevier Inc. All rights reserved.

    A detailed understanding of renal surgical anatomy is necessary to optimize preoperative planning and operative technique and provide a basis for improved outcomes. To evaluate the literature regarding pertinent surgical anatomy of the kidney and related structures, nephrometry scoring systems, and current surgical strategies for partial nephrectomy (PN). A literature review was conducted. Surgical renal anatomy fundamentally impacts PN surgery. The renal artery divides into anterior and posterior divisions, from which approximately five segmental terminal arteries originate. The renal veins are not terminal. Variations in the vascular and lymphatic channels are common; thus, concurrent lymphadenectomy is not routinely indicated during PN for cT1 renal masses in the setting of clinically negative lymph nodes. Renal-protocol contrast-enhanced computed tomography or magnetic resonance imaging is used for standard imaging. Anatomy-based nephrometry scoring systems allow standardized academic reporting of tumor characteristics and predict PN outcomes (complications, remnant function, possibly histology). Anatomy-based novel surgical approaches may reduce ischemic time during PN; these include early unclamping, segmental clamping, tumor-specific clamping (zero ischemia), and unclamped PN. Cancer cure after PN relies on complete resection, which can be achieved by thin margins. Post-PN renal function is impacted by kidney quality, remnant quantity, and ischemia type and duration. Surgical renal anatomy underpins imaging, nephrometry scoring systems, and vascular control techniques that reduce global renal ischemia and may impact post-PN function. A contemporary ideal PN excises the tumor with a thin negative margin, delicately secures the tumor bed to maximize vascularized remnant parenchyma, and minimizes global ischemia to the renal remnant with minimal complications. In this report we review renal surgical anatomy. Renal mass imaging allows detailed delineation of the

    Acute renal failure (ARF) may be due to obstructive uropathy or renal parenchymal disease. Twenty-five children with acute renal failure secondary to renal parenchymal disease underwent ultrasonographic examination of the kidneys. Changes of renal size and cortical echogenicity were correlated with renal function. All patients presented with bilaterally enlarged kidneys with the exception in renal function resulted in normalization of renal size. With regard to cortical echogenicity two groups were formed. Group A comprised 11 patients whose kidneys had the same echogenicity as the liver, while in group B the kidneys were more echogenic (14 patients). Cortical echogenicity was always increased. Determination of creatinine levels showed a statistically significant difference between group A (3.32 mg% ± 1.40 S.D.) and group B (5.95 mg% ± 1.96 S.D.), p < 0.001. Changes in renal function were paralleled by rapid changes in renal size and cortical echogenicity. (orig.)

    The frequent application of ultrasound and radiological imaging for non-urological indications in recent years has resulted in an increase in the diagnosis of small renal masses. The treatment options for patients with a small renal mass include active surveillance, surgery (both open and minimally invasive) as well as ablative techniques. As there is a risk for metastatic spread even in small renal masses surgical extirpation remains the treatment of choice in most patients. Ablative procedures, such as cryoablation and radiofrequency ablation are appropriate for old and multi-morbid patients who require active treatment of a small renal mass. Active surveillance is an alternative for high-risk patients. Meticulous patient selection by the urologist and patient preference will determine the choice of treatment option in the future.

    Our knowledge of the spectrum of renal abscesses has increased as a result of more sensitive radiologic techniques. The classification of intrarenal abscess now includes acute focal bacterial nephritis and acute multifocal bacterial nephritis, as well as the previously recognized renal cortical abscess, renal corticomedullary abscess, and xanthogranulomatous pyelonephritis. In general, the clinical presentation of these entities does not differentiate them; various radiographic studies can distinguish them, however. The intrarenal abscess is usually treated successfully with antibiotic therapy alone. Antistaphylococcal therapy is indicated for the renal cortical abscess, whereas therapy directed against the common gram-negative uropathogens is indicated for most of the other entities. The perinephric abscess is often an elusive diagnosis, has a more serious prognosis, and is more difficult to treat. Drainage of the abscess and sometimes partial or complete nephrectomy are required for resolution. 73 references

    Full Text Available Terminal lucidity is a term used in the medical literature to determine the improvement of mental functioning shortly before death, even among patients with serious and long-term disorders. In 19th century, cases of mind clarity recovery shortly before death, were often recognized by doctors and interpreted as a sign of an impending death. In 20th century, the interest in this phenomenon decreased and then, virtually disappear. In recent years, on the wave of publications concerning near death experiences and related events such as the end of life experiences, papers about the improvement of mental functioning shortly before death, exponentially grew and got a new name, terminal lucidity. In this paper, an overview of the available literature is presented to outline the historical, phenomenological and clinical picture of this phenomenon and its possible implications for medical care and future studies.

    Research into transition metal complexes bearing multiply bonded main-group ligands has developed into a thriving and fruitful field over the past half century. These complexes, featuring terminal M═E/M≡E (M = transition metal; E = main-group element) multiple bonds, exhibit unique structural properties as well as rich reactivity, which render them attractive targets for inorganic/organometallic chemists as well as indispensable tools for organic/catalytic chemists. This fact has been highlighted by their widespread applications in organic synthesis, for example, as olefin metathesis catalysts. In the ongoing renaissance of transition metal-ligand multiple-bonding chemistry, there have been reports of M═E/M≡E interactions for the majority of the metallic elements of the periodic table, even some actinide metals. In stark contrast, the largest subgroup of the periodic table, rare-earth metals (Ln = Sc, Y, and lanthanides), have been excluded from this upsurge. Indeed, the synthesis of terminal Ln═E/Ln≡E multiple-bonding species lagged behind that of the transition metal and actinide congeners for decades. Although these species had been pursued since the discovery of a rare-earth metal bridging imide in 1991, such a terminal (nonpincer/bridging hapticities) Ln═E/Ln≡E bond species was not obtained until 2010. The scarcity is mainly attributed to the energy mismatch between the frontier orbitals of the metal and the ligand atoms. This renders the putative terminal Ln═E/Ln≡E bonds extremely reactive, thus resulting in the formation of aggregates and/or reaction with the ligand/environment, quenching the multiple-bond character. In 2010, the stalemate was broken by the isolation and structural characterization of the first rare-earth metal terminal imide-a scandium terminal imide-by our group. The double-bond character of the Sc═N bond was unequivocally confirmed by single-crystal X-ray diffraction. Theoretical investigations revealed the presence

    Full Text Available Abstract The renal artery pseudoaneurysm embody a rare vascular complication coming of percutaneous procedures, renal biopsy, nephrectomy, penetrating traumas and more rarely blunt traumas. The clinical can be vary according the patient, the haematuria is the symptom more commom. Is necessary a high level of clinical suspicion for your diagnosis, this can be elucidated by through complementary exams as the eco-color Doppler and the computed tomography scan (CT. This report is a case of a patient submitted a right percutaneous renal biopsy and that, after the procedure started with macroscopic haematuria, urinary tenesmus and hypogastric pain. The diagnosis of pseudoaneurysm was given after one week of evolution when the patient was hospitalized because gross haematuria, tachycardia, hypotension and hypochondrium pain. In the angiotomography revealed a focal dilation of the accessory right renal inferior polar artery, dilation of renal pelvis and all the ureteral course with presence hyperdenso material (clots inside the middle third of the ureter. The treatment for the majority of this cases are conservative, through arterial embolization, indicated for thouse of smaller dimensions in patients who are hemodynamically stable. However, it was decided by clinical treatment with aminocaproic acid 1 g, according to previous studies for therapy of haematuria. The patient received discharge without evidence of macroscopic haematuria and with normal renal ultrasound, following ambulatory care.

    In selected patients with hypertension, renal artery (RA) stenting is used to treat significant atherosclerotic stenoses. However, blood pressure often remains uncontrolled after the procedure. Although catheter-based renal denervation (RDN) can reduce blood pressure in certain patients with resistant hypertension, there are no data on the feasibility and safety of RDN in stented RA. We report marked blood pressure reduction after RDN in a patient with resistant hypertension who underwent previous stenting. Subsequently, radiofrequency ablation was investigated within the stented segment of porcine RA, distal to the stented segment, and in nonstented RA and compared with stent only and untreated controls. There were neither observations of thrombus nor gross or histological changes in the kidneys. After radiofrequency ablation of the nonstented RA, sympathetic nerves innervating the kidney were significantly reduced, as indicated by significant decreases in sympathetic terminal axons and reduction of norepinephrine in renal tissue. Similar denervation efficacy was found when RDN was performed distal to a renal stent. In contrast, when radiofrequency ablation was performed within the stented segment of the RA, significant sympathetic nerve ablation was not seen. Histological observation showed favorable healing in all arteries. Radiofrequency ablation of previously stented RA demonstrated that RDN provides equally safe experimental procedural outcomes in a porcine model whether the radiofrequency treatment is delivered within, adjacent, or without the stent struts being present in the RA. However, efficacious RDN is only achieved when radiofrequency ablation is delivered to the nonstented RA segment distal to the stent. © 2014 American Heart Association, Inc.

    Full text: Renal artery stenosis (RAS) is a common condition that may lead to hypertension, progressive renal dysfunction and cardiovascular morbidity. Catheter-based therapy for symptomatic, haemodynamically significant, RAS has become the preferred method of revascularization. Balloon angioplasty has been the traditional treatment of choice for fibromuscular dysplasia, however stents are increasingly used for the treatment of atheromatous lesions; in many cases-such as in ostial lesions-, direct stenting is strongly indicated. Despite the increased use of endovascular therapy for renal artery stenosis, there is still controversy regarding the optimal management and the net benefit of this treatment. Several randomized trials of balloon angioplasty or stenting for renal artery stenosis compared with medical therapy alone have been conducted, however these could not show definite advantage of endovascular therapy. Problems encountered with those trials include enrollment of small number of patients, frequent crossover from medical to interventional therapy compromising the intention-to-treat results, or selection of patients that are not expected to show clear benefit. The Angioplasty and Stenting for Renal Artery Lesions (ASTRAL) is the most important of these trials; however, it,s study design was faulty and therefore did not provide conclusive evidence to answer the question of whether angioplasty and stenting or medical therapy is the best treatment for haemodynamically significant RAS. All expectations are now focused on the Cardiovascular Outcomes in Renal Atherosclerotic Lesions (CORAL) trial which was designed to answer the same question, and its methodologies took into consideration the weaknesses of the ASTRAL trial. Regarding stent device itself, it seems that the optimal design is probably a stainless steel, laser cut, open-cells stent mounted on a rapid exchange delivery balloon catheter compatible with 0.014-in and 0.018-in guidewire.

    Full Text Available Although sickle cell anemia and sickle cell disease produce a variety of functional renal abnormalities they uncommonly cause end stage renal failure. Renal transplantation has been a successful alternative for the treatment of the rare terminal chronic renal failure with outcomes comparable with non-sickle recipients. This approach, however, has not been often described on patients with renal failure associated with SC hemoglobinopathy. Here we report the outcomes of two patients with chronic renal failure due to SC hemoglobinopathies who underwent renal transplantation. At the time of the transplantation they were both severely anemic and had frequent vasoocclosive pain crises. Both patients evolved with good allograft function, near normal hematological parameters, and very rare pain crisis, thirteen and eight years after transplant. These cases illustrate that terminal renal failure due to SC hemoglobinopathy can be successfully managed by renal transplantation and satisfactory long-term results are achievable not only in terms of renal allograft function but also of their hematological condition.Embora a anemia falciforme e as síndromes falciformes freqüentemente causem várias alterações funcionais renais, não é comum a insuficiência renal terminal. Nestes casos, o transplante renal é uma alternativa que se acompanha de resultados comparáveis aos obtidos em receptores sem hemoglobinopatias. Esta estratégia terapêutica tem sido, no entanto, pouco relatada para portadores de hemoglobinopatia SC. Este relato descreve a evolução de dois pacientes portadores de hemoglobinopatia SC que foram submetidos ao transplante renal. No momento do transplante ambos apresentavam severa anemia e crises dolorosas freqüentes. Os pacientes evoluíram com boa função do enxerto, parâmetros hematológicos quase normais e praticamente assintomáticos do ponto de vista da hemoglobinopatia, treze e oito anos após o transplante.

    A pregnant woman presented at gestational week 28 with loss of consciousness and profound polyuria. Further characterization revealed osmotic diuresis due to massive glycosuria without hyperglycemia. Glycosuria reduced substantially postpartum, from approximately 100 to approximately 30 g/1.73 m2 per day. DNA sequencing analysis of the SLC5A2 gene encoding the renal glucose transporter SGLT2 showed a homozygous frame-shift mutation (occurring after the glutamine at amino acid 168 and leading to premature termination of the protein at amino acid 186) diagnostic of familial renal glycosuria. Pregnant women with familial renal glycosuria can be at risk of profound polyuria during pregnancy due to the associated increase in glycosuria. These findings also have implications for the use of SGLT2 inhibitors in clinical practice. Published by Elsevier Inc.

    Since the mid-1960's, microburst/windshear events have caused at least 30 aircraft accidents and incidents and have killed more than 600 people in the United States alone. This study evaluated alternative means of alerting an airline crew to the presence of microburst/windshear events in the terminal area. Of particular interest was the relative effectiveness of conventional and data link ground-to-air transmissions of ground-based radar and low-level windshear sensing information on microburst/windshear avoidance. The Advanced Concepts Flight Simulator located at Ames Research Center was employed in a line oriented simulation of a scheduled round-trip airline flight from Salt Lake City to Denver Stapleton Airport. Actual weather en route and in the terminal area was simulated using recorded data. The microburst/windshear incident of July 11, 1988 was re-created for the Denver area operations. Six experienced airline crews currently flying scheduled routes were employed as test subjects for each of three groups: (1) A baseline group which received alerts via conventional air traffic control (ATC) tower transmissions; (2) An experimental group which received alerts/events displayed visually and aurally in the cockpit six miles (approx. 2 min.) from the microburst event; and (3) An additional experimental group received displayed alerts/events 23 linear miles (approx. 7 min.) from the microburst event. Analyses of crew communications and decision times showed a marked improvement in both situation awareness and decision-making with visually displayed ground-based radar information. Substantial reductions in the variability of decision times among crews in the visual display groups were also found. These findings suggest that crew performance will be enhanced and individual differences among crews due to differences in training and prior experience are significantly reduced by providing real-time, graphic display of terminal weather hazards.

    Renal colic in pregnant women is a serious condition, mainly when is associated with fever. Our retro-prospective study analyzes 111 cases managed conservatively or with endourological procedures for renal colic--insertion of JJ stents and percutaneous nephrostomy. Clinical evolution determined the insertion of JJ stents in 60 cases and the failure of this procedure imposed percutaneous nephrostomy in 5 cases. In 56 cases urinary tract infection was associated and in 2 cases, despite all efforts, the patients deceased due to sever sepsis. The immediate drainage of the upper urinary tract for renal colic in pregnancy is the recommended treatment, especially when the pain is associated with fever. JJ stens were well tolerated, even when they were replaced after 3 months. Pregnant women with a history of UTI or stone disease should be carefully followed-up.

    A total of 174 patients underwent simple nephrectomy in case of clinically operable kidney cancer without demonstrable metastases. Of these 85 received preoperative irradiation to the kidney and the regional lymph nodes (3000-4000 rad in 3-4 weeks). Prognosis was not influenced by preoperative irradiation. The preoperatively assessable prognostic criteria were sex and sedimentation rate: ESR >= 30 and being male worsened prognosis. The clinical T-categories of the UICC were not related to prognosis. Of the microscopic examination of the nephrectomy specimen, renal vein invasion and to a lesser extent a low degree of differentiation appeared to worsen prognosis. The prognostic influence of the P-categories was caused by a higher incidence of renal vein involvement in case of higher P-category. The most important prognostic factors - ESR, renal vein involvement, and sex - were not interrelated. Elective chemotherapy, radiation therapy, and hormone therapy could be considered in certain high-risk groups. (orig.)

    Scintigraphy is useful for monitoring perfusion and function of renal transplant, as well as for diagnosing miscellaneous surgical. This non-invasive imaging technique, which uses no deleterious products, is an attractive alternative for patients. This is especially true for those patients in early post-transplant course, with immunity depression and often impairment of renal function. Otherwise, multiple indices with a large range of inter-patient values has not favoured a methodological and interpretative consensus. Furthermore, the poor specificity of renogram patterns does not allow for discrimination of all etiologies with only one scintigraphy. Nevertheless, follow-up with iterative scintigraphy may be helpful due to the high intra-patient reproducibility and to the early appreciate change of parameters, according to clinical and histological renal post-transplant outcome.

    2013-06-01

    The heliospheric termination shock is a vast, spheroidal shock wave marking the transition from the supersonic solar wind to the slower flow in the heliosheath, in response to the pressure of the interstellar medium. It is one of the most-important boundaries in the outer heliosphere. It affects energetic particles strongly and for this reason is a significant factor in the effects of the Sun on Galactic cosmic rays. This paper summarizes the general properties and overall large-scale structure and motions of the termination shock. Observations over the past several years, both in situ and remote, have dramatically revised our understanding of the shock. The consensus now is that the shock is quite blunt, is with the front, blunt side canted at an angle to the flow direction of the local interstellar plasma relative to the Sun, and is dynamical and turbulent. Much of this new understanding has come from remote observations of energetic charged particles interacting with the shock, radio waves and radiation backscattered from interstellar neutral atoms. The observations and the implications are discussed.

    Full Text Available Leiomyosarcomas are rare malignant tumors of the kidney. They may arise from the renal capsule, renal vein, renal pelvic musculature or renal parenchyma. Renal pelvis is an uncommon site of occurrence, with around 10 cases reported in the literature so far. Here we present a 60-year-old male who presented with increased urinary frequency, lower limb weakness, anorexia and weight loss. Imaging showed a right renal mass. A renal cell carcinoma was suspected clinically. A right nephrectomy was performed, which showed a large circumscribed mass in the hilar region. Histology revealed a tumor mass arising from the renal pelvis. The tumor was composed of spindle cells arranged in fascicles. Immunohistochemistry showed tumor cells to be positive for smooth muscle actin (SMA and desmin (Des and negative for cytokeratin (CK, HMB 45, CD117 (C-kit, and CD34. That confirmed the diagnosis of leiomyosarcoma.

    Essential hypertension remains one of the biggest challenges in medicine with an enormous impact on both individual and society levels. With the exception of relatively rare monogenetic forms of hypertension, there is now general agreement that the condition is multifactorial in nature and hence requires therapeutic approaches targeting several aspects of the underlying pathophysiology. Accordingly, all major guidelines promote a combination of lifestyle interventions and combination pharmacotherapy to reach target blood pressure (BP) levels in order to reduce overall cardiovascular risk in affected patients. Although this approach works for many, it fails in a considerable number of patients for various reasons including drug-intolerance, noncompliance, physician inertia, and others, leaving them at unacceptably high cardiovascular risk. The quest for additional therapeutic approaches to safely and effectively manage hypertension continues and expands to the reappraisal of older concepts such as renal denervation. Based on the robust preclinical and clinical data surrounding the role of renal sympathetic nerves in various aspects of BP control very recent efforts have led to the development of a novel catheter-based approach using radiofrequency (RF) energy to selectively target and disrupt the renal nerves. The available evidence from the limited number of uncontrolled hypertensive patients in whom renal denervation has been performed are auspicious and indicate that the procedure has a favorable safety profile and is associated with a substantial and presumably sustained BP reduction. Although promising, a myriad of questions are far from being conclusively answered and require our concerted research efforts to explore the full potential and possible risks of this approach. Here we briefly review the science surrounding renal denervation, summarize the current data on safety and efficacy of renal nerve ablation, and discuss some of the open questions that need

    Background: Renal leiomyomas are rare benign tumors of the kidney which can be found at autopsy as small capsular nodules in about 5% of cases. The clinical incidence of such lesions is much smaller, and only case reports or small series have been reported in the imaging literature. Purpose: To describe the imaging characteristics observed in a series of eight patients with pathology-proven asymptomatic leiomyomas of the kidney. Material and Methods: We reviewed the imaging findings observed in eight patients with pathologically proven asymptomatic renal leiomyomas discovered during studies performed for reasons unrelated to the kidney. All patients had undergone computed tomography (CT), two ultrasonography, and one magnetic resonance imaging (MRI). Results: Lesions ranged in size from 1.2 to 13 cm. Six were at the periphery of the kidney, compressed its outer surface, but did not cause disruption of the cortex; two involved the renal cortex. All had regular outer margins. A cleavage plane between the tumor and the kidney was revealed at CT and/or ultrasonography in three of the cases located at the periphery. At ultrasonography, leiomyomas appeared hypoechogenic. At CT, they were slightly hyperdense before contrast medium injection; all were hypodense to the renal cortex after contrast medium. Four were homogeneous, two were slightly heterogeneous, and the remaining two were frankly heterogeneous. The lesion studied by MRI, which was homogeneous at the postcontrast CT study, had a heterogeneous structure on both T1- and T2-weighted images, with internal areas of hypointensity on T1. Conclusion: There are some imaging findings that can help to suggest the diagnosis of renal leiomyomas. First, their density: all tumors examined before contrast were hyperdense to the kidney, with density similar to that of muscles, and all had lower enhancement than the adjacent renal parenchyma. Second, the location and margins of the tumors: most were peripheral, without

    A group of 110 consecutive renal stone formers were screened for distal renal tubular acidosis (RTA) using morning fasting urinary pH (mfUpH) levels followed by a short ammonium chloride loading test in patients with levels above 6.0. In 14 patients (12.7%) a renal acidification defect was noted...... RTA in renal stone formers. Regardless of whether the acidification defect is primary or secondary to stone formation, however, all renal stone formers with distal RTA can expect to benefit from prophylactic alkaline therapy and it is recommended that the screening procedure, which is easy to use...

  1. Resolution and termination

    Full Text Available The resolution, the termination and the reduction of labour conscription are regulated by articles 1549-1554 in the new Civil Code, which represents the common law in this matter. We appreciate that the new regulation does not conclusively clarify the issue related to whether the existence of liability in order to call upon the resolution is necessary or not, because the existence of this condition has been inferred under the previous regulation from the fact that the absence of liability shifts the inexecution issue on the domain of fortuitous impossibility of execution, situation in which the resolution of the contract is not in question, but that of the risk it implies.

    Full Text Available El trasplante es el mejor tratamiento para la insuficiencia renal, de acuerdo con la biomedicina; sin embargo, es una tecnología cara. Este artículo examina las dificultades económicas y sus efectos en personas con trasplante renal, pero sin protección social en salud. Para el estudio se desarrolló una investigación cualitativa en México. Participaron 21 pacientes trasplantados; se aplicaron entrevistas semiestructuradas, y se realizó un análisis de contenido. Los resultados muestran que las personas enfermas enfrentan dificultades económicas, debido a los costes de las terapias renales, particularmente, de las medicinas. Todo ello tiene efectos negativos: las personas con pocos recursos dejan el tratamiento con medicamentos, abandonan el protocolo, no asisten a las consultas médicas y disminuyen los gastos domésticos, incluyendo el de alimentación; además de suponer una merma en los ingresos familiares. En conclusión, el trasplante renal empobrece a las personas enfermas sin protección social en salud; es urgente la implementación de un sistema de protección social para esta población.

    As angioplasty and operative techniques have become more precise and successful, so have evaluation techniques. Preoperative arteriography is indispensible for deciding on the appropriate treatment modality and the specifics of the procedure. Arteriography, therefore, remains the cornerstone in managing renovascular hypertension and renal arterial disease

    In this paper, we study how access pricing affects network competition when subscription demand is elastic and each network uses non-linear prices and can apply termination-based price discrimination. In the case of a fixed per minute termination charge, we find that a reduction of the termination charge below cost has two oppos- ing effects: it softens competition but helps to internalize network externalities. The former reduces mobile penetration while the latter boosts it. We find that fi...

    Full Text Available Imaging technology with its advancement in the field of urology is the boon for the patients who require minimally invasive approaches for various kidney disorders. These approaches require a precise knowledge of the normal and variant anatomy of vascular structures at the hilum of the kidney in terms of their pattern of arrangement and division. The present paper describes a bilateral anomalous arrangement of the structures at the renal hilum as well as their peculiar branching pattern which is of clinical and surgical relevance. Multiple branching of the renal vessels was observed in both kidneys due to which the hila were congested. The right renal artery immediately after its origin divided into 2 branches. The upper branch represented an aberrant artery whereas the lower branch gave 5 divisions. The left renal artery also divided into 2 branches much before the hilum as anterior and posterior divisions. The anterior branch took an arched course and gave 6 branches. The posterior branch gave 3 terminal branches before entering the renal substance. In addition to anomalous hilar structures, normal architecture of both kidneys was altered and the hilum of the left kidney was found on its anterior surface.

    Renal dysfunction is common in liver diseases, either as part of multiorgan involvement in acute illness or secondary to advanced liver disease. The presence of renal impairment in both groups is a poor prognostic indicator. Renal failure is often multifactorial and can present as pre-renal or intrinsic renal dysfunction. Obstructive or post renal dysfunction only rarely complicates liver disease. Hepatorenal syndrome (HRS) is a unique form of renal failure associated with advanced liver dise...

    Three adult patients with unilateral renal agenesis/total dysplasia (= aplasia) and with an early chronic renal failure are presented. One patient had renal agenesis without ureter bud and ureteric ostium on one side, and reflux pyelonephritis on the other; one had small compact total renal dysplasia (= aplasia) on one side, while chronic uric acid nephropathy (chronic renal disease as a cause of gout) was diagnosed on the other; the third patient had a total large multicystic dysplasia on one side, and on the other a segmental large multicystic dysplasia. Radiological steps and radiodiagnostic criteria are discussed and the combination of urogenital and extraurogenital anomalies is referred to. (orig.)

    Full Text Available La sustitución valvular ha modificado la historia natural de la valvulopatía aórtica y constituye la piedra angular del tratamiento quirúrgico. Sin embargo, conlleva de por vida un elevado riesgo acumulado de complicaciones relacionadas con las prótesis (tromboembolismos, endocarditis, deterioro estructural de las prótesis biológicas, reintervenciones y con la necesidad de anticoagulación. Por eso, la reparación valvular emerge con fuerza como alternativa en el manejo de la insuficiencia aórtica, particularmente en los individuos más jóvenes. Se realiza hoy con una mortalidad quirúrgica baja y los grupos quirúrgicos con gran experiencia reportan buenos resultados en términos de durabilidad. Además, el desarrollo y la difusión de las técnicas de cirugía conservadora de la válvula aórtica para el tratamiento del aneurisma de aorta ascendente han mejorado nuestra comprensión del papel destacado de la raíz de aorta en la función valvular y han conducido al desarrollo de soluciones quirúrgicas adaptadas a cada caso de insuficiencia aórtica, con o sin enfermedad de la raíz.

    Full Text Available INTRODUCCIÓN. El objetivo de esta investigación fue determinar los factores de riesgo asociados al fallo renal agudo (FRA en un grupo de niños con sepsis grave atendidos entre enero del 2004 y diciembre del 2008. MÉTODOS. Se realizó un estudio observacional y analítico con una muestra de 171 pacientes. Se constituyeron dos grupos: el de estudio, integrado por 38 pacientes con estado de choque séptico o disfunción múltiple de órganos (DMO y FRA, y un grupo control, conformado por 133 niños en igual estadio de sepsis pero con función renal normal. Se revisaron las historias clínicas y se tuvieron en cuenta variables epidemiológicas, factores de riesgo de FRA y evolución de los casos. RESULTADOS. La incidencia de FRA fue del 22,2 %, y aunque disminuyó considerablemente en los 3 últimos años del estudio, la mortalidad fue del 42,1 %, mayoritariamente en el DMO (89,5 %. Se encontró dependencia entre la insuficiencia renal y la respuesta diurética no adecuada a la fluidoterapia (51,2 %, la inestabilidad hemodinámica por más de 24 h (46,5 %, la disfunción miocárdica (43,3 % y el uso de medicamentos nefrotóxicos (42,8 %. CONCLUSIONES. La respuesta diurética no adecuada a la fluidoterapia, la inestabilidad hemodinámica por más de 24 h, la disfunción miocárdica y el uso de medicamentos nefrotóxicos incrementan el riesgo de FRA en la sepsis grave, la cual duplica la mortalidad en relación con los pacientes que conservan la función renal. No obstante, la prevención de las formas graves de sepsis y un tratamiento adecuado de ésta disminuyen la incidencia de FRA.INTRODUCTION: The aim of present research was to determine the risk factor associated with the acute renal failure (ARF in a group of children with severe sepsis seen between January, 2004 and December, 2008.

Así como la influencia en los ingresos globales del hospital por IC.MATERIAL Y MÉTODOS: Estudio de cohortes retro y prospectivo de 169 pacientes con ICC, incluidos en dos consultas monográficas similares, pertenecientes a dos hospitales de diferente ámbito asistencial (comarcal y provincial. Se evalúan porcentaje de pacientes que recibe fármacos de 1º línea, la adherencia al seguimiento y se compara los ingresos por ICC realizados el año previo y posterior al seguimiento. Para conocer el impacto de estas consultas, en base a los datos de los centros, se analiza la evolución en el nº de ingresos totales y estancias medias por ICC (GRDs 127, 544 durante los años 2001-2009. Coincide el ecuador de este pe-riodo con la puesta en marcha de estas consultas.RESULTADOS: Los pacientes sometidos al seguimiento recibieron fárma-cos de 1º línea en un porcentaje elevado (97.8% para IECAS/ARA-II,y 88% para BB, con una adherencia al seguimiento muy alta (90% y con una reducción de los reingresos de hasta un 69%, con respecto al año previo. Desde los datos facilitados por ambos hospitales, se observa una disminución de la estancia hospitalaria global del servicio de Medicina interna por ICC de 3.5 días, un aumento de pacientes atendidos en Medi-cina interna y una disminución de los ingreso por ICC. CONCLUSIONES: El seguimiento por internistas y enfermería de los pacien-tes con ICC y comorbilidad, basado en una atención continuada e integral, en la información y en la disponibilidad, es un buen método no solo para disminuir reingresos hospitalarios , sino que además puede influir en la me-jora de las cifras globales de la hospitalización por

    Full Text Available La insuficiencia cardiaca congestiva constituye una de las principales causas de hospitalización, morbilidad y mortalidad en los países occidentales. Aunque en Colombia no se conocen con exactitud su incidencia y prevalencia, recientemente se ha planteado que está adquiriendo proporciones epidémicas. Diversos estudios demuestran que los pacientes con esta condición presentan alteraciones cognitivas tales como pérdida de la memoria y déficit de atención, las cuales se relacionan con un peor pronóstico clínico. Los síntomas cognitivos no sólo indican una enfermedad cardiaca más avanzada, sino que también se asocian con pobre adherencia al tratamiento y menor calidad de vida. A pesar de su importancia, los mecanismos fisiopatológicos de esta relación no son claros. Se sugiere que las alteraciones hemodinámicas cerebrales derivadas de la disminución en el gasto cardiaco, así como de la presencia de múltiples microinfartos cerebrales secundarios a microembolismos, podrían relacionarse con alteraciones cognitivas en dichos pacientes. Sin embargo, hasta el momento no existen suficientes datos que permitan confirmar esta hipótesis.Congestive heart failure is a leading cause of hospitalization, morbidity and mortality in the Western countries. Although its incidence and prevalence in Colombia is not fully established, it seems to be acquiring epidemic proportions. Several studies have shown that patients with congestive heart failure present cognitive impairments such as memory loss and attention deficit, which are associated with a worse clinical prognosis. The cognitive symptoms are not only indicative of a more advanced heart disease but are also associated with poor adherence to treatment and lower quality of life. Despite their importance, the pathophysiological mechanisms of this relationship have not been clearly defined. It has been suggested that the cerebral hemodynamic changes resulting from a decrease in cardiac output

El objetivo de este trabajo fue comparar varios métodos para modelizar la variable hospitalizaciones y determinar el efecto de los factores asociados con los ingresos hospitalarios en casos incidentes de IC. Método: Se realizó un estudio de cohortes restrospectivo con información extraída de la historia clínica electrónica de Atención Primaria (AP. Se incluyeron pacientes mayores de 24 años que habían realizado al menos 1 consulta en AP durante el año 2006. Se analizaron las hospitalizaciones registradas de casos incidentes de IC entre 2006 y 2010 o hasta su fallecimiento y se compararon modelos de regresión de Poisson, Binomial Negativa (BN, inflados con ceros y de Hurdle para identificar factores asociados a las hospitalizaciones. Resultados: Se identificó a 3.061 personas con IC en una cohorte de 227.984 pacientes. Respecto a los factores asociados con las hospitalizaciones y según el modelo de regresión BN inflado con ceros, los pacientes con valvulopatías (OR=2,01; IC95%: 1,22-3,30 o en tratamiento con antitrombóticos (OR=3,45; IC95%: 1,61-7,42 o diuréticos (OR=2,28; IC95%:1,13-4,58 tuvieron mayor probabilidad de hospitalización. Los factores asociados a una mayor tasa de ingresos fueron tener valvulopatías (IRR=1,37; IC95%: 1,03-1,81 o diabetes mellitus (IRR=1,38, 1,07-1,78 y estar en tratamiento con calcioantagonistas (IRR=1,35; IC95%: 1,05-1,73 o IECAS (IRR=1,43; IC95%:1,06- 1,92. Haber tenido derivaciones a cardiología tuvo efecto protector (IRR=0,86; IC95%: 0,76-0,97. Conclusión: El modelo de regresión que tiene mejor ajuste es el BN inflado con ceros.

    'Terminal discharges' are carried out in Singapore for patients who wish to die at home. However, if due diligence is not exercised, parallels may be drawn with euthanasia. We present a theoretical discussion beginning with the definition of terminal discharges and the reasons why they are carried out in Singapore. By considering the intention behind terminal discharges and utilising a multidisciplinary team to deliberate on the clinical, social and ethical intricacies with a patient- and context-specific approach, euthanasia is avoided. It is hoped that this will provide a platform for professionals in palliative medicine to negotiate challenging issues when arranging a terminal discharge, so as to avoid the pitfall of committing euthanasia in a country such as Singapore where euthanasia is illegal. It is hoped that a set of guidelines for terminal discharges may someday be realised to assist professionals in Singapore and around the world.

    The purpose of this study is to determine characteristic CT findings in renal abscess. Twenty cases of renal abscess were retrospectively analyzed for CT findings relating to the shape and extent of the abscess, change of nephrogram, peripheral rim enhancement, wedge-shaped enhancement on delayed scans, enlargement of the kidney involved and associated findings. Seven patients had a renal abscess at the right kidney, nine at the lift kidney and two bilaterally. The abscesses were round in 18 cases and finger-like in two. Rim enhancement around renal abscess was seen in four cases (20%). Changes in the nephrogram around the abscess were seen in 12 cases (60%). In all six patients who had undergone delayed postcontrast scans, wedge-shaped enhancement was shown around the abscess (100%). In the observation of the extent of renal abscesses, 14 cases were within the kidney, six cases extended the beyond renal capsule, and two were loculated in the renal fascia itself. Renal enlargement was seen in nine cases (45%). These results suggest that CT findings such as delayed wedge-shaped enhancement, change of nephrogram, peripheral rim enhancement, renal enlargement, and associated findings are valuable for diagnosis, and that CT also gives information concerning the extent, evolution and complication of a renal abscess
