Prevalence and Predisposing Factors for Bundle Branch Block in Patients Starting Dialysis  

British Library Electronic Table of Contents (United Kingdom)

Introduccion y objetivos Aunque los bloqueos de rama (BR) se consideran hallazgos frecuentes, la informacion sobre su prevalencia real en la poblacion general es escasa, y es inexistente en los pacientes en dialisis. El objetivo es establecer la prevalencia del BR completo en la poblacion que inicia dialisis y los factores relacionados con su aparicion. Como analisis adicional, se explora su asociacion con la mortalidad y con la aparicion de un evento cardiovascular. Metodos Se incluyo a los pacientes que iniciaron dialisis en nuestro centro entre el 1 de noviembre de 2003 y el 31 de diciembre de 2006. Todos fueron sometidos a valoracion cardiologica al inicio de dialisis. Determinamos el BR y su relacion con factores clinicos y parametros ecocardiograficos y bioquimicos. Los pacientes fue...

Importance of Recognizing Occult Renal Disease in Hypertensive Patients  

British Library Electronic Table of Contents (United Kingdom)

Introduccion y objetivos La enfermedad renal oculta (ERO) es una entidad que define los estadios mas iniciales de insuficiencia renal y no se detecta con los metodos usados habitualmente. El objetivo es determinar la prevalencia de ERO en los pacientes hipertensos en consultas de cardiologia y su relacion con los distintos factores de riesgo y tratamientos cardiovasculares. Metodos. Estudio observacional, transversal, retrospectivo y multicentrico que se llevo a cabo en 1.214 hipertensos de consultas de cardiologia. Resultados . Se analizo a 1.190 pacientes (98%). El filtrado glomerular (FG) fue calculado (MDRD) por el cardiologo responsable en el 11% de los pacientes. Tras su determinacion a posteriori, el 9,5% presentaba ERO, mas probablemente mujeres, con mas edad, mas antecedents de di...

Use of sodium aluminate in waste water treatment plants: wishes of saving money and innovating; Uso del aluminato sodico en las EDAR: una propuesta para innovar y economizar costes de explotacion  

Energy Technology Data Exchange (ETDEWEB)

Most waste water treatment plants have processes to remove nutrients in order to avoid eutrophication in water receiving bodies. Regarding phosphorus removal. the most common option is chemical precipitation with ferric or aluminical precipitation with ferric or aluminium salts. We show here the successful experience carried out by the WWTP of Blanes and the company Safloc. A method ato remove phosphorus from waste water was developed by adding sodium aluminate. The use of this compound has turned out to be a sustainable way for this purpose in terms of costs, reliability and minimization of sludge production. (Author)

Treatment and Course of Community-Acquired Pneumonia Caused by Atypical Pathogens  

British Library Electronic Table of Contents (United Kingdom)

Objetivo Estudiar la evolucion de un grupo de neumonias extrahospitalarias causadas por germenes atipicos (Mycoplasma pneumoniae, Legionella spp., Coxiella burnetii y Chlamydophila pneumoniae) en funcion del tratamiento empirico recibido. Pacientes y metodos Entre enero de 1996 y febrero de 2001 ingresaron en nuestra unidad 390 casos de neumonia, de los que 89 estaban causados por germenes atipicos. Los pacientes se dividieron retrospectivamente en 2 grupos segun el tratamiento empirico pautado: grupo A, al que se habia proporcionado cobertura frente a germenes atipicos (quinolonas o macrolidos), y grupo B, al que no se habia proporcionado dicha cobertura. Se estudio la evolucion segun las diferencias entre ambos grupos en la estancia hospitalaria, la resolucion radiologica, el reingreso e...

Update on erectile dysfunction treatment for aging men  

British Library Electronic Table of Contents (United Kingdom)

Resumen Estudios epidemiologicos recientes, muestran claramnete la incidencia de la disfuncion erectil con la edad. Por lo tanto, los profesionales sanitarios que se ocupan de las personas de edad avanzada, deberian preparar cuidadosamente el diagnostico y el abordaje de la disfuncion erectil. Es innegable que la introduccion de los inhibidores de la fosfodisterasa tipo 5 (PDE5Is) ha revolucionado el tratamiento de la disfuncion erectil. Los clinicos deberian conocer el potencial de los efectos adversos asociados con el uso de PDE5Is cuando se aconseja a los pacientes. Otras terapias suplementarias y de segunda/tercera linea para la disfuncion erectil, que incluyen las inyecciones intracavernosas, la aplicacion transuretral de medicacion, la testosterona, los sistemas de vacion peneano, la...

The use of "1"3"1I-radioiodine in diagnostic and treatment: estimated risk in Guanabara  

International Nuclear Information System (INIS)

The "1"3"1-radioiodine use in Guanabara area, during 1972-1973, is analysed. References are made to the radiation levels delivered to thyroid, bone marrow and gonads in a population of 27000 people examined by tracer techniques, 190 submitted to hyperthyroidism treatment and 50 treated for thyroid cancer. The pertinent literature gives some data concerning radiation induced cancer (leukaemia and thyroid cancer). By this, it was possible to estimate the probability of tumour occurrence in that population, assuming a linear relationship between dose and effect. The conclusions are the followings: 1 - there are many duties in this field at the present; 2 - the leukaemia incidence related to the 131-radioiodine use is negligible, either in diagnostic or therapeutic modalities; 3 - the possibility of thyroid tumors induced by radiation is real, specially in hyperthyroidism treatment; 4 - the use of tracer techniques that cause lower irradiation to the pacient is ...

Reliability of diagnostic imaging techniques in suspected acute appendicitis: proposed diagnostic protocol; Indicacion de las tecnicas de diagnostico por la imagen en la sospecha de apendicitis aguda: propuesta de protocolo diagnostico  

Energy Technology Data Exchange (ETDEWEB)

To study the utility of ultrasound and computed tomography (CT) in case of suspected appendicitis. To determine the diagnostic yield in terms of different clinical contexts and patient characteristics. to assess the costs and benefits of introducing these techniques and propose a protocol for their use. Negative appendectomies, complications and length of hospital stay in a group of 152 patients with suspected appendicitis who underwent ultrasound and CT were compared with those of 180 patients who underwent appendectomy during the same time period, but had not been selected for the first group: these patients costs for each group were calculated. In the first group, the diagnostic value of the clinical signs was also evaluated. The reliability of the clinical signs was limited, while the results with ultrasound and CT were excellent. The incidence of negative appendectomy was 9.6% in the study group and 12.2% in the control group. Moreover, there were fewer complications and a shorter ...

Proposal to neutralize acid fluids from wells in the Los Humeros, Pue., geothermal field; Propuesta para la neutralizacion de fluidos acidos provenientes de pozos del campo geotermico de Los Humeros, Pue.  

Energy Technology Data Exchange (ETDEWEB)

Neutralizing an acidic fluid consists of adding a sodium hydroxide solution to neutralize the H group of acids, therefore increasing the pH. The injection of sodium hydroxide has to be continuous and at a proper depth inside the well to protect against the corrosion of casing and surface equipment. Neutralization is a common practice used in geothermal fields, such as at The Geysers in the US and Miravalles in Costa Rica-places where aggressive fluids cause problems for extracting and using geothermal fluids commercially. A zone surrounding wells H-4, H-16 and H-29 in the northern section of the Los Humeros, Pue., geothermal field, known as the Colapso Central, has shown evidence of aggressively acidic fluids. Several wells drilled in the area had to be repaired, thus plugging and isolating the deepest production zones. Well H-43 was drilled two years ago in the northern zone of the field, and even though it is not located in the aggressive-fluid zone, the well presents mineralogical ...
