RESUMO

OBJETIVO: Analizar las características clínicas, el manejo y los resultados de los pacientes con endoftalmitis estéril asociada con el factor de crecimiento endotelial antivascular intravítreo. MÉTODOS: Serie de casos de observación retrospectiva de pacientes con endoftalmitis estéril después de inyecciones intravítreas anti-VEGF. Se han revisado los datos clínicos de pacientes tratados con anti-VEGF intravítreos durante un año. Se analizan los que han presentado un episodio de endoftalmitis estéril y se estudia su causalidad y manejo. RESULTADOS: Siete pacientes tuvieron un inicio de endoftalmitis estéril en los 4días posteriores a la inyección intravítrea (aflibercept n = 5 y ranibizumab n = 2). Estos pacientes tienen alguna condición neovascular activa: degeneración macular relacionada con la edad (n = 4), neovascularización coroidea miope (n = 1) o edema macular: edema macular diabético (n = 1), oclusión de la vena retiniana ramificada (n = 1). Los signos y síntomas compartidos incluyeron pérdida de visión indolora, células en cámara anterior o vítrea y falta de hipopión. En todos los pacientes, la agudeza visual volvió a estar dentro de una línea de agudeza basal. CONCLUSIÓN: Diferenciar casos de endoftalmitis estéril de infecciosa puede ser un desafío. Es crucial diferenciar ambas entidades, ya que un buen diagnóstico determina el pronóstico visual. Debemos ser conscientes de una inflamación mínima después de repetidas inyecciones intravítreas para establecer el tratamiento adecuado


PURPOSE: Analyze clinical features, management and outcomes of patients with sterile endophthalmitis associated with intravitreal antivascular endothelial growth factor. METHODS: Observational retrospective case series of patients with sterile endophthalmitis following anti-VEGF intravitreal injections. Clinical data of patients treated with intravitreal anti-VEGFs during one year have been revised. Those who have presented an episode of sterile endophthalmitis are analyzed and their causality and management are studied. RESULTS: Seven patients have had a sterile endophthalmitis onset within 4days after intravitreal injection (aflibercept n = 5 and ranibizumab n = 2). These patients have some active neovascular condition: age related macular degeneration (n = 4), myopic choroidal neovascularization (n = 1) or macular edema: diabetic macular edema (n = 1), branch retinal vein occlusion (n = 1). Shared signs and symptoms included painless vision loss, anterior chamber and vitreous cell and lack of hypopyon. In all patients, visual acuity returned to within one line of baseline acuity. CONCLUSIÓN: Differentiating cases of sterile from infectious endophthalmitis may be challenging. It is crucial to differentiate both entities as a good diagnosis determines the visual prognosis. We should be aware of minimal inflammation after repeated intravitreal injections in order to establish the adequate treatment

RESUMO

La disección submucosa endoscópica submucosa (DSE) y la resección mucosa endoscópica mucosa (RME) o mucosectomía son las principales técnicas empleadas en la extirpación endoscópica de pólipos del tubo digestivo. En ambas técnicas se inyecta una solución submucosa para crear un habón debajo de la lesión que separe la mucosa de la capa muscular propia. Esto permite una mejor delimitación de la lesión y facilita su resección. En la práctica clínica, se han probado diferentes soluciones para este uso, utilizándose en la mayoría de los casos fuera de indicación en ficha técnica y sin control galénico, fisicoquímico ni microbiológico, a pesar de ser soluciones de administración parenteral. El objetivo de este trabajo es llevar a cabo una revisión de las principales soluciones utilizadas, así como de sus limitaciones y de los principales avances realizados en este ámbito


Endoscopic submucosal dissection (ESD) and endoscopic mucosal resection (EMR) are the main techniques used in the removal of intestinal polyps. In both techniques a submucosal solution is injected to create a hub under the lesion that separates the mucosa from the muscular layer itself. This allows a better delimitation of the lesion and facilitates its resection. In clinical practice, many solutions have been tested for this use, being used in most cases out off-label and without galenic, physicochemical or microbiological control, despite being parenteral administration solutions. The objective of this study is to carry out a review of the main solutions used, as well as their limitations and the main advances made in this area

RESUMO

PURPOSE: The objective of the study is to provide toxicological information through the HET-CAM test of Fluconazole and Voriconazole eye drops prepared commonly in Pharmacy Services for the treatment of fungal keratitis. METHOD: Experimental Study. The ocular toxicity of topical voriconazole 10 mg/ml and fluconazole 2 mg/ml were evaluated by the hen's egg test (HET) on the chorioallantoic membrane (CAM). The effects on blood vessels were based on its behavior during 300 seconds and processes that may occur at each time, then we calculated the irritation index (is, irritation score). RESULTS AND CONCLUSIONS: Both eye drops, voriconazol and fluconazole have been proven to be safe, since the IS that we obtained was zero for both samples and did not present significant signs of irritation. Therefore, these eyedrops are considered suitable for ocular use from a toxicological point of view.


OBJETIVO: El objetivo del estudio es aportar información toxicológica mediante el ensayo HET-CAM, de los colirios de Fluconazol y Voriconazol elaborados de manera habitual en los Servicios de Farmacia para el tratamiento de las queratitis fúngicas. MÉTODOS: Estudio experimental en el que se ensaya la potencial toxicidad ocular del colirio de voriconazol 10 mg/ml y fluconazol 2 mg/ml mediante el método Hen s Egg Test-Chorioallantoic Membrane (HET-CAM). Los resultados se fundamentan en la observación de los posibles procesos dañinos que pudiesen ocurrir en los vasos sanguíneos de la membrana corioalantoidea del embrión de pollo durante un tiempo de contacto de 300 segundos, calculándose posteriormente el índice de irritación (IS, Irritation Score). RESULTADOS Y CONCLUSIONES: Se obtienen IS nulos para ambas muestras, no mostrando por tanto indicios de irritación aguda apreciables, considerándose por tanto aptos para su utilización desde el punto de vista toxicológico.
