Abstract: The collaboration between researchers and instructors to develop a basic education program that attends to a highly vulnerable population enabled the pinpointing of the role of formally assigned accompaniment to pedagogical advisers within the Mexican education system. We adapted a modality of participative action research to the conditions of the basic education program; we recorded class sessions and analyzed, along with the instructors, specific moments to stimulate reflection about the achievement of an innovation goal. The collaboration was organized in such a way that some typical tensions of this type of action research were effectively resolved, and the results clearly demonstrated that this kind of research can lead to greater benefits for instructor development and the functions of pedagogical advisers. The research identifies the resources and mechanisms that the Mexican education system needs to modify in order to achieve instructor accompaniment and development that deliver long-lasting results through the personnel dedicated to this task.

Resumen: La colaboración entre investigadores y docentes de un programa de educación básica que atiende a una población de alta vulnerabilidad permitió precisar la función del acompañamiento asignado formalmente a los asesores pedagógicos dentro del sistema educativo mexicano. Adaptamos una modalidad de investigación acción participativa a las condiciones del programa de educación básica, registramos en video sesiones de clase y analizamos, junto con los docentes, momentos específicos para incitar a la reflexión sobre el logro de un objetivo de innovación. La colaboración se organizó de tal manera que se pudieron resolver efectivamente algunas tensiones típicas de este tipo de investigación acción y dejó claro que de ella pueden derivarse beneficios más amplios para el desarrollo docente y las funciones de los asesores pedagógicos. La investigación señala los recursos y mecanismos que el sistema educativo mexicano requiere modificar para realizar un acompañamiento y un desarrollo docentes que den resultados perdurables mediante el personal destinado a esa tarea.

Background: Systemic vasculitis are a group of heterogeneous diseases characterized by inflammation and necrosis of blood vessel walls. The etiology is not known, but geographic and environmental factors are implicated. Aim: To describe the clinical features of microscopic polyangiitis (MPA) and Wegener's granulomatosis (WG) in a Chilean cohort of patients. Patients and methods: Retrospective review of the medical records of 123 patients with the diagnosis of systemic vasculitis (65 MPA and 58 WG), seen from 1990 to 2001. The diagnosis were made based on the American College of Rheumatology and Chapel Hill criteria. Results: The mean follow-up for MPA was 15 months (1-120) and for WG, 20 months (1-120). The median age (years) at diagnosis for MPA was 61 (19-82) and WG 50 (20-82). Gender distribution was similar in both groups (male: 68% and 57% respectively).The main clinical features in the MPA group were renal involvement (68%), peripheral nervous system involvement (57%), pulmonary hemorrhage (28%), and skin disease (32%). In the WG group were alveolar hemorrhage (62%), renal involvement (78%), paranasal sinus involvement (57%), and ocular disease (26%). In both, creatinine levels above 2.0 mg/dl were associated with a higher mortality (p< 0.01). ANCA by immunofluorescence was performed in 56 MPA patients (75% had pANCA, 4% had cANCA and 21% were ANCA negative) and in 55 WG patients (17% had pANCA, 79% had cANCA and 4% were ANCA negative). Global mortality was 18% and 17% respectively, and the most common causes of death were infections. Conclusions: The clinical features of our patients are similar to other published data. In our WG and MPA patients the main predictor for death was a serum creatinine above 2 mg/dl. (Rev Méd Chile 2005; 133: 273-8)

The study identified the body weight perception of 827 women selected in a health center in Belo Horizonte, Minas Gerais, Brazil, comparing it with the overweight anthropometric diagnostic. The subjects of the study were asked about their weight and classified as overweight or ideal weight. A high percentage of women of this study overestimated their perceived self-image. Differences of +/- 8 and +/- 4 kg between reported weight and measured weight would be expected in 95% of the lower an higher family income, respectively, compromising the first group's related weight.

El presente estudio evalúa la percepción del peso corporal de 827 mujeres reclutadas en un centro de salud de Belo Horizonte, comparándolas con el diagnóstico antropométrico de sobrepeso. Se les pidió a dichas mujeres que dijesen cuánto pesaban y que clasificasen su peso como ideal o como sobrepeso. Un alto porcentaje sobreestimó su imagen corporal. Se espereban errores entre más o menos 8 y 4 kg entre el peso mencionado y el efectivamente medido en el 95% de la población de bajo y de mayor ingreso familiar, respectivamente, comprometiendo, así, la validez del peso mencionado en el primer grupo.

Foi pedido aos sujeitos do estudo que dissessem seu peso e se classificassem como acima do peso ou com peso ideal. Altas porcentagens das mulheres estudadas superestimaram sua imagem corporal percebida. Erros de +/- 8 e +/- 4 kg de diferença entre o peso referido e o aferido seriam esperados em 95% da população de baixa e de maior renda familiar, respectivamente, comprometendo assim, a validade do peso referido no primeiro grupo.
