Intraprostatic ethanol injection as an alternative therapy in patients with benign prostatic hyperplasia. / Inyección intraprostática de etanol como terapia alternativa en pacientes con hiperplasia prostática benigna.

INTRODUCTION: Benign prostatic hyperplasia is a high prevalence worldwide pathology. Amongst its therapeutic options, there are minimally invasive techniques that use locally injected substances (such as ethanol), which produce a chemoablation of this organ. OBJECTIVE: The present work aims to evaluate the efficacy of intraprostatic ethanol injection in the treatment of benign prostatic hyperplasia. MATERIAL AND METHODS: A prospective study was carried out, consisting of patients with symptomatic benign prostatic hyperplasia, who were injected with 95% ethanol transrectally, in a 25% prostate volume dose, divided into 3punctures per each lobe. Follow-up time was 12 months. RESULTS: The procedure was well tolerated. The mean urethrovesical catheter stay time was 10.68 days (CI 8.61-13.75, Range 3-30). The score on the international scale of prostatic symptoms improved by 47.58% (p<0.05) and quality of life by 43.94% (p>0.05); prostatic volume was reduced by 35.03% (p<0.05) as well as the post-voiding residual by 58.61% (p>0.05) The maximum urinary flow was increased by 84.83% (p<0.05). The most frequent side effects were hematuria, irritative symptoms and infection. CONCLUSIONS: Intraprostatic ethanol injection can be an effective, non-surgical alternative in the treatment of patients with benign prostatic hyperplasia.

Kinesiología respiratoria en pacientes asmáticos en edad escolar / Respiratory physiotherapy in asthmatic school-age patients

The role of respiratory physiotherapy in the asthmatic school-age patient is based on three pillars: evaluative, therapeutic and educational, which have gradually been incorporated and developed. Respiratory physiotherapy has advanced significantly, incorporating cardiorespiratory function tests into its diagnostic and follow-up services, allowing the execution of these tests at the primary level of healthcare. Manual and instrumental respiratory physiotherapy techniques increase the level of control of asthmatic patients. The evidence found in literature invites us to innovate the methodology we use at educational interventions in children and adolescents, with the inclusion of new technologies to motivate and generate meaningful learning in patients as well as in their parents/caregivers, thus improving adherence to treatment and achieving the desired control of the disease

El rol de la kinesiología respiratoria en el paciente asmático en etapa escolar, se basa en tres pilares: evaluativo, terapéutico y educativo, los cuales se han ido paulatinamente incorporando y desarrollando con el paso del tiempo. La kinesiología respiratoria ha avanzado significativamente, incorporando pruebas de función cardiorrespiratoria a su arsenal de prestaciones diagnósticas y de seguimiento, permitiendo la ejecución de éstas en el nivel primario de atención. Mediante la utilización de técnicas manuales e instrumentales, permite potenciar el nivel de control de los pacientes asmáticos. La literatura nos invita a innovar en la metodología a utilizar para realizar una intervención educativa efectiva en niños y adolescentes, incluyendo las nuevas tecnologías disponibles para motivar y generar un aprendizaje significativo en el paciente como en los padres/cuidadores, mejorando así la adherencia al tratamiento y por ende logrando el anhelado control de la enfermedad

High energy electron beams characterization using CaSO4:Dy+PTFE phosphors for clinical therapy applications.

In the present work high energy electron beam dosimetry from linear accelerator (LINACs) for clinical applications using dysprosium doped calcium sulfate embedded in polytetrafluorethylene (CaSO4:Dy+PTFE) was studied. The irradiations were carried out using high electron beams (6 to 18 MeV) from a linear accelerator (LINAC) Varian, CLINAC 2300C/D, for clinical practice purpose. The electron irradiations were obtained using the water solid in order to guarantee electronic equilibrium conditions (EEC). Field shaping for electron beams was obtained with electron cones. Glow curve and other thermoluminescent characteristics of CaSO4:Dy+PTFE were conducted under high electrons beams irradiations. The TL response of the pellets showed an intensity peak centered at around 215 °C. TL response of CaSO4:Dy+PTFE as a function of high electron absorbed dose showed a linearity in a wide range. To obtain reproducibility characteristic, a set of pellets were exposed repeatedly for the same electron absorbed dose. The results obtained in this study can suggest the applicability of CaSO4:Dy+PTFE pellets for high electron beam dosimetry, provided fading is correctly accounted for.

Antibióticos profilácticos en cirugía urológica / Prophylactics antibiotics in urologic surgery

La infección es la complicación más temida de las cirugías, si bien éstas pueden presentarse en sitios alejados al operado, como el caso de las neumonías, lo más frecuente es que se relacione con la zona intervenida y en particular con la herida operatoria. Se prefiere hablar de Infección del Sitio Operatorio (ISO) en forma técnica para referirnos a esta afección. Se define como ISO: Infecciones que ocurren dentro de los 30 días después de la cirugía si no hay un implante o dentro de un año si hay un implante in situ. Además la infección parece, clínicamente, estar relacionada con la cirugía.
