RESUMEN

Introducción: Las infecciones oculares son patologías frecuentes asociadas a secuelas graves como la ceguera y se convierten en un potencial problema en salud pública. Su perfil epidemiológico, en cuanto a su etiología, es conocido a nivel mundial, pero los perfiles locales son desconocidos, limitando los esfuerzos terapéuticos dirigidos para compartir dicho problema. Objetivo: Caracterizar los principales gérmenes encontrados en los cultivos tomados de la córnea y la secreción conjuntival de pacientes de un centro de referencia oftalmológica de Medellín. Método: Estudio descriptivo, observacional y retrospectivo a partir de los resultados de cultivos, realizando un análisis en función de variables categóricas emitiendo porcentajes y frecuencias. Resultados: Se obtuvieron 176 cultivos en total: el 61.4% fue de córnea y el 34.1% de conjuntiva; los gérmenes más frecuentemente aislados fueron Pseudomonas en un 25%, Staphylococcus aureus con un 20% y Fusarium con un 15%. Conclusión: Los gérmenes más frecuentes que encontramos en este estudio coinciden con los que habitualmente se reportan en la literatura

Background: Eye infections are frequent pathologies associated with serious sequelae such as blindness and they become a potential public health problem. Its epidemiological profile, in terms of its etiology, is known worldwide, but the local profiles are unknown, limiting targeted therapeutic efforts to share this problem. Objective: To characterize the main germs found in cultures taken from the cornea and conjunctival secretion of patients at an ophthalmological reference center in Medellín. Method: Descriptive, observational, and retrospective study based on the results of cultures, carrying out an analysis based on categorical variables, issuing percentages and frequencies. Results: A total of 176 cultures were obtained: 61.4% were from the cornea and 34.1% from the conjunctiva; the most frequently isolated germs were Pseudomonas in 25%, Staphylococcus aureus with 20% and Fusarium with 15%. Conclusion: The most frequent germs that we found in this study coincide with those that are usually reported in the literature

RESUMEN

OBJECTIVES: We aimed to explore the impact of the time interval between symptoms and diagnosis on post-operative infective endocarditis (IE) survival. METHODS: From 2014 to 2019, data from 93 consecutive patients undergoing cardiac surgery due to left-sided±right-sided IE were prospectively recorded in our specific electronic database. Patients were classified into 2 groups according to time interval between first clinical symptoms and definitive endocarditis diagnosis: patients with early diagnosis (≤8 days) and patients with late diagnosis (>8 days). Follow-up was 100% complete, and follow-up mean time was 471 days. RESULTS: Among the 93 patients undergoing cardiac surgery due to definite left-sided IE, 48 (51.6%) had early-diagnosed IE whereas 45 (48.4%) presented with a late-diagnosed IE. Unadjusted and propensity score adjusted mid-term survival Kaplan-Meier analysis showed significantly worse survival of patients belonging to the early-diagnosis group (p .019 and .049 respectively). Multivariable Cox regression analysis identified only one predictor of mid-term mortality: EuroSCORE II (Hazard ratio 1.03, 95% CI 1.01-1.05, p .0008). CONCLUSION: The association in the Kaplan-Meier analysis between "early-diagnosis group" and mortality suggests that this group of patients presents clinical characteristics of severity that, on the one hand, speed up the diagnostic process and on the other, converge in the determination of a higher euroSCORE II value, which is the only independent predictor of mid-term mortality according to our analysis

OBJETIVOS: Nuestro objetivo fue explorar el impacto del intervalo de tiempo entre los síntomas y el diagnóstico en la supervivencia postoperatoria de la endocarditis infecciosa (EI). MÉTODOS: De 2014 a 2019, los datos de 93 pacientes consecutivos intervenidos de cirugía cardíaca por EI definitiva izquierda±derecha se registraron prospectivamente en nuestra base de datos electrónica. Los pacientes se clasificaron en 2 grupos según el intervalo de tiempo entre los primeros síntomas clínicos y el diagnóstico definitivo de endocarditis: pacientes con diagnóstico temprano (≤propensity score: 8 días) y pacientes con diagnóstico tardío (>propensity score: 8 días). El seguimiento fue del 100% completo, y el tiempo medio de seguimiento fue de 471 días. RESULTADOS: Entre los 93 pacientes que se sometieron a cirugía por EI definitiva del lado izquierdo, 48 (51,6%) tenían un diagnóstico temprano de EI, mientras que 45 (48,4%) presentaban un diagnóstico tardío de EI. El análisis de Kaplan-Meier no ajustado y el ajustado con propensity score mostró una supervivencia significativamente peor de los pacientes que pertenecen al grupo de diagnóstico temprano (p 0,019 y 0,049, respectivamente). El análisis de regresión de Cox multivariable identificó solo un predictor de mortalidad a medio plazo: EuroSCORE II (razón de riesgo: 1,03; IC 95%: 1,01-1,05; p 0,0008). CONCLUSIÓN: La asociación en el análisis de Kaplan-Meier entre «diagnóstico temprano de EI» y mortalidad sugiere que este grupo de pacientes presenta características clínicas de gravedad que, por un lado aceleran el proceso diagnóstico, y por el otro confluyen en la determinación de un EuroSCORE II más alto, que sí es un predictor independiente de mortalidad

RESUMEN

AIMS: To analyse the ultrasound anatomy of bifurcation lesions {1,1,0},{0,1,0} and {1,0,0} of the Medina classification in order to identify predictors of angiographic side branch (SB) damage after main branch (MB) stenting. METHODS AND RESULTS: One hundred and ten patients with Medina classification bifurcation lesions of {1,1,0},{0,1,0} and {1,0,0} were recruited. An intravascular ultrasound study (IVUS) was performed on the MB before treatment, after stent implantation and after SB intervention. A quantitative analysis was conducted in combination with a qualitative study of the carina morphology and plaque distribution. Ostial SB damage (an increase of the percentage of ostial stenosis by QCA ≥30%) was observed in 51 lesions (48%) after MB stenting. The baseline IVUS identified a carina with a spiky morphology ("eyebrow" sign) in 51 bifurcations. In 41 out of 51 bifurcations with this sign, ostial SB damage was induced after stenting the MB due to carina shift (p<0.01). Narrower angiographic angles were associated with the presence of the "eyebrow" sign (62º±23º vs. 76º±24º, p<0.05). Plaque located at the carina was associated with a lower rate of ostial SB damage (29%) when compared with those lesions with no plaque exhibiting at the carina (51%), p<0.05. CONCLUSIONS: The "eyebrow" sign is a powerful predictor of ostial SB damage after stent implantation in the MB in bifurcation coronary lesions without plaque involving the SB.
