Este artículo da cuenta de la marcha  que se realiza del 8 al 21 de marzo de 2012, a través de diez provincias de Ecuador,  organizada por actores indígenas, pobladores urbanos y gobiernos regionales que luchaban por el agua y contra la minería, en el marco del gobierno de la Revolución Ciudadana. Se indaga sobre si la marcha logra posicionar en el escenario político la crítica a la producción minera y si constituye un momento de inflexión del ciclo de reflujo que vivieron los movimientos sociales desde principios de siglo. La respuesta es negativa a la primera pregunta y respecto a la segunda plantea que no se da tanto una inflexión como una transformación en la naturaleza de los movimientos sociales. El artículo  resume un  estudio que examina fuentes documentales y material audiovisual, está  sustentado en entrevistas a medio centenar de informantes calificados y en el análisis del  discurso del presidente Correa;  asume el enfoque del análisis de demandas y repertorios, inspirad...

To determine the efficacy of infliximab treatment in refractory posterior uveitis in Behçet's disease after withdrawal of infusions. Four patients with posterior uveitis secondary to Behçet's disease were treated with infliximab until complete remission and were followed after withdrawal of infusions. Intra-ocular inflammation was assessed using the binocular indirect ophthalmoscopy score, best-corrected visual acuity (BCVA) and foveal thickness measured by optic coherence tomography (OCT). All the patients included in the study were treated with infliximab for a minimum of 12 months and were in complete remission. None of the patients were taking steroids or immunosuppressants. Main follow-up after withdrawal of infusions was 7.5 months. Two out of four patients (50%) maintained complete remission of posterior uveitis. BCVA was stable in seven eyes. OCT showed worsening in macular edema in the two eyes of the patients with reactivation. Infliximab is an efficient long-term treatment for refractory posterior uveitis. Repeated infusions are required to maintain long-term remission which may be sustained on discontinuation of the drug.

To report a case of juxtafoveal choroidal neovascularization in a patient with presumed ocular histoplasmosis syndrome (POHS) who was treated with intravitreal injection of bevacizumab (Avastin) as initial treatment. A 23-year-old woman with POHS presented with sudden dimness of vision and metamorphopsia in the right eye. The patient was examined with ophthalmoscopy, fluorescein angiography, and optical coherence tomography (OCT). Fundus examination, fluorescein angiography, and OCT of the right eye revealed a juxtafoveal choroidal neovascularization. Intravitreal injection of bevacizumab was performed with a postoperative improvement of visual acuity and resolution of the distortion. This case report describes a case of juxtafoveal choroidal neovascularization associated with POHS that responded remarkably well to intravitreal injection of bevacizumab.
