Observation of Oscillatory Radial Electric Field Relaxation in a Helical Plasma.

Measurements of the relaxation of a zonal electrostatic potential perturbation in a nonaxisymmetric magnetically confined plasma are presented. A sudden perturbation of the plasma equilibrium is induced by the injection of a cryogenic hydrogen pellet in the TJ-II stellarator, which is observed to be followed by a damped oscillation in the electrostatic potential. The waveform of the relaxation is consistent with theoretical calculations of zonal potential relaxation in a nonaxisymmetric magnetic geometry. The turbulent transport properties of a magnetic confinement configuration are expected to depend on the features of the collisionless damping of zonal flows, of which the present Letter is the first direct observation.

[Urinary incontinence and prostate cancer: A rehabilitation program design]. / La incontinencia urinaria en el cáncer de próstata: diseño de un programa de rehabilitación.

INTRODUCTION AND OBJECTIVE: This article presents the design and implementation of a rehabilitation program based on the muscular exercises of pelvic floor, incorporating the strength resistance work. MATERIALS AND METHODS: The design in quasi-experimental. The sample is formed by 33 participants in treatment phase. The variable studied are: anthropometrics variables, variables related to IU evolution (intensity, difficulty, frequency and activities limitation), obesity, fatigue and pain, muscular strength and quality of life. Measures pre (0 week) and post test (24 weeks) are taken with the aim of evaluate intra-subject change. Statistic analysis is made with t Student-fisher test, Wilcoxon or U Man Whitney, and X(2) test. Analysis was performed with SPSS program version 15. Signification level chosen was 5%. RESULTS: After 24 weeks of program an improvement was identify in: anthropometric variables waist-to- hip ratio (p

La incontinencia urinaria en el cáncer de próstata: diseño de un programa de rehabilitación / Urinary incontinence and prostate cancer: A rehabilitation program design

Introducción y objetivo: Este trabajo presenta el diseño e implementación de un programa progresivo de rehabilitación basado en los ejercicios musculares del suelo pélvico, incorporando el trabajo muscular de fuerza contrarresistencia. Material y método: El diseño del estudio es casi experimental. La muestra es de 33 participantes en fase de tratamiento. Las variables de estudio son las antropométricas, las relacionadas con la evolución de la incontinencia urinaria (IU) (intensidad, dificultad, frecuencia y limitación de las actividades), la obesidad, fatiga y dolor, la fuerza muscular y la calidad de vida (CdV). Para evaluar el cambio intrasujeto se tomaron medidas pretest (semana 0) y postest (semana 24). En el análisis estadístico se utilizan las pruebas t Student-Fisher, Wilcoxon o U de Mann Whitney y el test del χ2. El análisis se realiza con el programa SPSS versión 15. El nivel de significación escogido es del 5%. Resultados: Al finalizar las 24 semanas del programa se identifica una disminución significativa de las variables antropométricas índice de cintura-cadera (p=0,003), perímetro de cintura (p≤0,001) y porcentaje de masa de grasa (p≤0,001); de las variables de IU: intensidad (p≤0,0001), frecuencia y dificultad y su relación con la limitación de las actividades (p≤0,0001), así como la relación existente entre la mejora de IU y la mejora de la CdV (p=0,039). Conclusiones: Queda científicamente demostrada la eficacia del programa progresivo de fuerza para disminuir la IU. La mejora de la CdV del hombre mayor con cáncer de próstata viene mediada por la mejora de la continencia urinaria (AU)

Analysis was performed with SPSS program version 15. Signification level chosen was 5%. Results: After 24 weeks of program an improvement was identify in: anthropometric variables waist-to- hip ratio (p=,003), waist perimeter (p≤,001), body fat percentage (p≤,001), IU intensity (p≤,0001), frequency and difficulty and they relation with activities limitation (p≤,0001), and also the existing relationship between the improvement of IU and the improvement of QoL (p=,039). Conclusions: The article establishes scientifically the efficacy of the progressive strength to diminish IU. The improvement of QoL of men with prostate cancer is mediated by the improvement of the urinary continence (AU)

Hipersensitivity to fruits in latex allergic patients.

In medical literature, there are many cases reported of anaphylaxis due to fruits, before or after allergic reactions to latex. We present two atopic patients, with allergy to latex (by clinical history, positive skin test and RAST). Both patients showed a positive skin test and RAST to fruits (banana, kiwi, avocado and chestnut), but clinically caused no symptoms.

Mustard allergy. Two anaphylactic reactions to ingestion of mustard sauce.

Two cases of anaphylactic reactions set off by the ingestion of a small amount of mustard sauce are described. Mediation by specific IgE to mustard was determined by skin prick tests and radioimmunoassay, which suggested a type I hypersensitivity mechanism. Despite the antigenic potency of mustard, a spice that is consumed frequently, very few cases of hypersensitivity from ingestion have been described.

Autoimmune neutropenia and thrombocytopenia associated with development of antibodies to human immunodeficiency virus.

We report on two patients with acute human immunodeficiency virus (HIV) infection, who developed an infectious mononucleosis-like clinical episode with thrombocytopenia and granulocytopenia. In both cases we detected the presence of IgG antigranulocyte antibodies and in one case the presence of IgG, IgM and IgA antiplatelet antibodies. The mechanisms of these cytopenias are discussed. The association between such autoimmune cytopenias and acute HIV infection has not been previously reported. We suggest testing for HIV seroconversion in patients with a seronegative infectious mononucleosis-like syndrome belonging to groups with a high risk for HIV infection.
