Pino,Mónica; Bravo,Luis;
Psykhe (Santiago) , 2005, DOI: 10.4067/S0718-22282005000100004
Abstract: the aim of this article is to present the results of a longitudinal study of a group of public school pupils on their visualperception, visual memory and visual-orthographic recognizing of words and their predictivity on early reading. the sample was comprised of 105 first grade students. the children were assessed using nine tests to measure visual and visual-ortographic perceptual recognition, and a test to measure their reading ability. results show that rey's test, which assesses visual perception ability, has a predictive value on initial reading in spanish speaking chilean children.
La Memoria Visual Como Predictor del Aprendizaje de la Lectura Visual Memory as Predictor of Reading Acquisition

Psykhe (Santiago) , 2005,
Abstract: Se presentan los resultados de un estudio longitudinal realizado en alumnos de escuelas municipales de Santiago de Chile, cuyo objetivo fue investigar la relación entre el reconocimiento visual-ortográfico, la percepción y la memoria visual con la lectura inicial. Especialmente se analizó la relación predictiva entre el reconocimiento perceptivo visual de la Figura Compleja de Rey, la memoria visual y el reconocimiento visual-ortográfico con el aprendizaje inicial de la lectura. La muestra estuvo conformada por 105 alumnos de primero básico. Los ni os se evaluaron mediante nueve pruebas destinadas al reconocimiento perceptivo visual y visual-ortográfico y una prueba utilizada para evaluar el aprendizaje de la lectura. Los resultados mostraron que la prueba de la Figura Compleja de Rey, que evalúa capacidad de percepción visual, predice significativamente el aprendizaje lector en el nivel inicial.

Abstract: to evalúate by ultrasonographic images carotid intima-media thickness (imt) as an early marker of cardiovascular risk (cvr) in patients with clinical and laboratory diagnosis of familial hypercholesterolemia (fhc), type 1 diabetes (dbt-1) and obesity (ob), compared to a healthy control group. materials and methods. a prospective, descriptive, and cross-sectional study. we evaluated the imt of common carotid (ce) arteries and included in a single dichotomic variable other structural modifications of the wall (atheromatous plaques and intima irregularities). us was blinded to the blood tests results (as recommended by the 2007 mannheim consensus) from 121 patients (aged 6 to 18 years): 24 fhc, 40 dbt-1, 43 ob, and 14 controls. patients with other diseases that could alter the arterial wall were excluded. variables were analyzed using the statistix 8 program. results. the three groups had a higher imt than the control group, with these differences being statistically significant. mean imt (mm) were 0.59 (0.31-2.15), p: 0.006, ci 0.06 to 0.36 in fhc; 0.48 (0.3-0.85), p: 0.001, ci 0.06-0.14 in obesity; and 0.46 (0.25-0.65), p: 0.0004, ci 0.03-0.13 in dbt-1. control group: 0.37 (0.30-0.45). the major difference was observed in fhc patients. no association was found between ldl-c valué and imt upon the examination, 62.5% were receiving pharmacotherapy. in dbt-1 no association was found between imt and the levéis of hbalc and lipids. in the ob group there was no association between imt and bmi z-score. atheromatous plaques and intima irregularities were found in 31% of fhc patients, 8% of dbt-1 patients, and 6% of ob patients. conclusión. ultrasonographic imt measurements demonstrated that patients with chronic diseases and increased cvr at adulthood presented early changes in the carotid intima-media at childhood. this allows clinical prevention strategies and therapeutic guidance.

Abstract: background: the guidelines for the treatment of severely burned patients, ineluded in the explicit guarantees in health care (ges), accept having a garces' index over 70, among others, as an inclusion criterion. this criterion allows elderly patients with small total burn surface area (tbsa) to have access to ges. aim: to analyze if a universal access to ges for this group of patients is justified. material and methods: revision of medical records of adult patients admitted to a burn service. causative agent, tbsa, associated illnesses and outcome were compared between 218 subjects aged 65 years or more and 720 subjects aged less than 65 years. results: older subjects had smaller tbsa, a lower prevalence of inhalation injury and more associated diseases. their lethality was three times greater than that of younger subjects and their risk of dying. when adjusting for tbsa, presence of inhalation injury and associated diseases was 11 times greater. conclusions: the inclusion of older people with lower tbsa in the explicit guarantees in health is fully justified, considering the lethality of burns in this age group.

Abstract: Objetivo: analizar retrospectivamente resultados y factores pronósticos de pacientes con cáncer cérvico uterino estadios IIB-IIIB tratados con radioquimioterapia concomitante. Materiales y métodos: desde septiembre 1999 a diciembre del 2002, 164 pacientes ingresaron con el diagnóstico de cáncer de cérvix, seleccionándose 83 en estadios IIB-IIIB, las que fueron tratadas con radioterapia y cisplatino semanal por cinco semanas. Resultados: el 89,15% completó cinco ciclos de quimioterapia. La mediana de sobrevida global fue de 41 meses, con una sobrevida global (SG), sobrevida libre de enfermedad (SLE) y sobreviva libre de recurrencia loco-regional (SLRLR) a tres a os de 68,8%, 66,3% y 83,1%, respectivamente. Factores pronósticos de sobrevida fueron etapa IIIB, diámetro tumoral clínico ≥ 7 cm, no realización de braquiterapia y enfermedad biparametrial. Conclusiones: el tratamiento con radioterapia y quimioterapia concomitante con cisplatino en pacientes con cáncer cervicouterino estadios IIB-IIIB, es posible de realizar en el Hospital Carlos Van Buren perteneciente al sistema de salud público chileno, con buena tolerancia, resultados y factores pronósticos similares a los de la literatura internacional. Objective: a retrospective study analysed results and prognostic factors regarding patients suffering from stage IIB-IIIB cervical carcinoma treated with cisplatin-based chemotherapy concurrently with standard radiotherapy. Material and methods: 164 patients were admitted to the hospital from September 1999 to December 2002 who had been diagnosed with cervical cancer; 83 patients suffering from stage IIB-IIIB were selected. Treatment consisted of radiotherapy plus weekly cisplatin-based chemotherapy lasting five weeks. Results: 89.15% of the patients received 5 cycles of chemotherapy. Median overall survival rate was 41 months, with 68.8% 3-year overall survival, 66.3% disease-free survival and 83.1% loco-regional disease-free survival rates. Prognostic factors for survival were: stage IIIB, ≥ 7 cm clinical tumour diameter, patients who had not undergone brachytherapy and biparametrial disease Conclusions: a radiation treatment and concurrent weekly cisplatin therapy regimen in patients suffering from stage IIB-IIIB cervical carcinoma proved feasible in the Carlos Van Buren Hospital (Chilean public health system) having good tolerance, results and prognostic factors similar to those reported in the international literature.

Abstract: Background: The guidelines for the treatment of severely burned patients, ineluded in the explicit guarantees in health care (GES), accept having a Garces' index over 70, among others, as an inclusion criterion. This criterion allows elderly patients with small total burn surface area (TBSA) to have access to GES. Aim: To analyze if a universal access to GES for this group of patients is justified. Material and Methods: Revision of medical records of adult patients admitted to a burn service. Causative agent, TBSA, associated illnesses and outcome were compared between 218 subjects aged 65 years or more and 720 subjects aged less than 65 years. Results: Older subjects had smaller TBSA, a lower prevalence of inhalation injury and more associated diseases. Their lethality was three times greater than that of younger subjects and their risk of dying. When adjusting for TBSA, presence of inhalation injury and associated diseases was 11 times greater. Conclusions: The inclusion of older people with lower TBSA in the explicit guarantees in health is fully justified, considering the lethality of burns in this age group.
