RESUMO
PURPOSE: We aimed to compare the visual outcomes after pars plana vitrectomy (PPV) versus tap and inject (T&I) in fungal endophthalmitis (FE) reported in the literature and to compare the findings from the literature with data from a reference centre. METHODS: We performed a systematic review and meta-analysis of studies reporting the use of PPV versus T&I in FE. We also performed a retrospective review of the clinical records of patients with endophthalmitis from a reference centre in Colombia. RESULTS: We included 13 studies with 334 eyes; 53.59% received PPV and 46.4% received T&I. The overall relative risk of improving ≥ 2 lines in PPV versus T&I was 0.98 (95% confidence interval [CI] 0.80-1.22; p = 0.88) with a mean difference of final visual acuity of 0.26 (95% CI 0.12-0.63; p = 0.18). There were no significant differences in subgroup analysis. Data from the reference centre included 32 endophthalmitis cases, 15.6% of which had a fungal aetiology (80% received PPV and 20% T&I). There were no significant differences in the subgroup analysis. CONCLUSIONS: Based on the findings from the literature and the reference centre, T&I is noninferior to PPV. This is the first meta-analysis in the literature evaluating these effects in FE. It is necessary to execute new prospective randomised controlled studies in patients with endophthalmitis.

A central retinal vein occlusion (CRVO) case in a patient developed with sudden blurred vision in some hemifield areas of his left eye, maintaining 20/20 vision 15-days after the COVID-19 vaccination. Initial retinal findings were venous dilation and tortuosity with dispersing dot hemorrhages. Fluorescein angiography (FA) and optical coherence tomography (OCT) confirmed a non-ischemic CRVO diagnosis, and a complete blood panel was requested with average results. An intravitreal steroid dose was applied. A decrease in best-corrected visual acuity (BCVA) (20/30) with more intraretinal hemorrhages was documented. An intravitreal dose of bevacizumab and oral apixaban were added with a final BCVA of 20/20 with decreased hemorrhages. There is no specific causal relationship between COVID-19 vaccines and CRVO. Without previous risk factors and positive treatment response, this case may correlate the first COVID-19 vaccine dose and the event.

Introducción: La oclusión combinada de la arteria y la vena central de la retina es un evento vascular poco frecuente, caracterizado por pérdida visual súbita y pronóstico reservado. Los pocos casos reportados se asocian con antecedentes de patología sistémica vasculítica, reumatológica, infecciosa o tumoral. Objetivo: Describir un caso de doble oclusión vascular retiniana secundario a síndrome de anticuerpos antifosfolípidos. Resumen del caso: Se reporta el caso de una paciente de 31 años con oclusión de vena y arteria central de la retina, con historia clínica y paraclínicos compatibles con un síndrome de anticuerpos antifosfolípidos de base, enfermedad de difícil manejo con un pobre pronóstico visual, con secuelas visuales graves, rápidas e irreversibles. Conclusiones: Las oclusiones vasculares combinadas de arteria y vena central de la retina son poco frecuentes. Se caracterizan por pérdida súbita de la visión y hallazgos clínicos propios de ambos tipos de oclusiones: palidez retinal, mancha de color rojo cereza, dilatación venosa, hemorragias en llama, edema de disco, etc. Por lo regular tiende a relacionarse con patologías infecciosas, autoinmunitarias o tumorales, entre otras, como es el caso del síndrome antifosfolípido. Las opciones terapéuticas son limitadas y la respuesta es incierta, con un mal pronóstico visual y secuelas irreversibles
Introduction: Combined vascular occlusion of the central retinal artery and vein is a rare vascular event, characterized by sudden visual loss and uncertain prognosis. The few cases reported in literature are associated with a history of vasculitic, rheumatological, infectious or tumoral pathology. Objective: To describe a mixed retinal vascular occlusion secondary to antiphospholipid antibody syndrome. Case summary: We report a case with mixed retinal vascular occlusion in a patient with history of antiphospholipid antibody syndrome , with poor visual prognosis, difficult treatment and severe irreversible sequelae. Conclusions: Combined retinal vascular occlusions are rare entities characterized by sudden vision loss and clinical findings of both types of occlusions: retinal pallor, cherry red spot, venous dilatation, hemorrhages, disc edema, etc. Usually, these are related to infectious, autoimmune or neoplasic diseases, like antiphospholipid syndrome. The therapeutic options are limited and their effectiveness is vague, leading to poor visual prognosis and irreversible sequelae

INTRODUCTION: Nitazoxanide is a member of a new class of drug, thiazolides, and it was discovered in 1984 with antimicrobial activity effect against anaerobic bacteria, Hepatitis virus, protozoa, and helminths. METHODS: A bibliometric study on four databases (1984-2016) - Medline, Scopus, LILACS, and SciELO - characterizing the global scientific production of nitazoxanide. We determined the quantity, quality (number of citations), and types of studies developed by each country, characterizing them by years, international cooperation, development, place of publication, authors (with its H-index), and groups with higher impact. RESULTS: There were 512 articles in Medline - the higher scientific production is from the USA (19.71%), Switzerland (7.51%), and Mexico (7.27%). There were 1,440 articles in Scopus - from the USA (8.98%), Mexico (2.13%), and India (1.65%). There were 405 articles in LILACS - from Mexico (4.69%), the USA (4.2%), and Peru (2.47%). There were 47 articles in SciELO - from Brazil (34.04%), Venezuela (21.28%), and Colombia (14.89%). The H-index of nitazoxanide is 75 - the USA (26), Egypt (12), and Canada (10) were the countries contributing more with that. CONCLUSIONS: Nitazoxanide research has been highly important. Nevertheless, it is relatively limited when compared with other drugs. Its research has been led by the USA, as revealed in this bibliometric assessment. Although some developing countries, where it is used especially for protozoa and helminths, probably have its influence, and this explains the fact that Mexico and India, among others, are the top countries in the scientific production of this anti-infective agent. This bibliometric study evidenced a relatively low number of publications, however, it has been increased in recent years.
RESUMO
Chikungunya fever, a viral disease epidemic in some parts of the world is newly introduced in the Americas. This is of considerable international concern, with a growing incidence owing to developing urbanization, tourism, and trade. Ocular manifestations of chikungunya fever are not frequent, but of great relevance. Common manifestations include conjunctivitis, optic neuritis, iridocyclitis, episcleritis, retinitis and uveitis. Diagnostic and monitoring investigations would include optical coherence tomography, fundus fluorescein and indocyanine green angiography, visual field analysis, and electrophysiologic tests. There have been no prospective, randomized therapeutic trials, and it is unclear if the disease is self-limiting or if treatment is actually beneficial. Prognosis varies, ranging from full resolution to permanent vision loss despite intervention.

Objetivos Determinar la prevalencia de potenciales interacciones farmacológicas entre azitromicina y diferentes antiarrítmicos del grupo IA y III en una base de datos de prescripción de medicamentos a nivel nacional durante el año 2012-2013. Métodos Estudio retrospectivo a partir de una base de datos poblacional de dispensación de medicamentos. Se extrajeron datos de los pacientes que recibieron azitromicina desde 1 de enero de 2012 a 30 junio de 2013, al igual que pacientes que recibieron este antibiótico en combinación a otros medicamentos con demostrado riesgo de provocar arritmias cardíacas al usarse concomitantemente. Se establecieron frecuencias y proporciones. Resultados Se identificaron 13 859 pacientes que recibieron azitromicina sola o en combinación con otros medicamentos. El tiempo promedio de uso fue 4,5±0,9 días; Un total de 702 pacientes (5,1 %) recibieron azitromicina más otros 19 fármacos de potencial riesgo. Los más frecuentemente asociados fueron: loratadina (77,1 %), difenhidramina (16,5 %) y amitriptilina (8,1 %). Las combinaciones con un solo medicamento fueron las más frecuentes (n=533, 75,9 %), con predominio de azitromicina+loratadina. El máximo número de fármacos combinados fue seis (n=2, 0,3 %). Conclusiones La identificación mediante bases de datos poblacionales la prescripción de medicamentos, es una manera eficaz de encontrar potenciales interacciones entre estos. La frecuencia de potenciales interacciones entre azitromicina y otros fármacos es común en pacientes colombianos. Se debe estimar el riesgo de ocurrencia de eventos cardiacos adversos.(AU)
Objective To determine the prevalence of potential drug interactions between azithromycin and different IA and III antiarrhythmic groups in a national database of drug prescriptions in 2012-2013. Methods Retrospective study based on a population database of medicine dispensation. Data from patients who received azithromycin between January 1, 2012 and June 30, 2013 were extracted along with data from patients who received azithromycin in combination with other medications shown to cause heart arrhythmias when used concomitantly. Frequencies and proportions were established. Results 13 859 patients receiving azithromycin alone or in combination with other drugs were identified. The average time of use was 4.5 ± 0.9 days. A total of 702 patients (5.1 %) received azithromycin plus 19 other potentially risky drugs. The most frequently associated were loratadine (77.1 %), diphenhydramine (16.5 %) and amitriptyline (8.1 %). Combinations with a single drug were the most frequent (n=533, 75.9 %), predominantly azithromycin+loratadine. The maximum number of combined drugs was six (n=2, 0.3 %). Conclusions Identification of drug prescriptions through population databases is an effective way to find potential drug interactions. The frequency of potential interactions between azithromycin and other drugs is common in Colombian patients. Future research should assess the risk of occurrence of adverse cardiac events.(AU)
