RESUMO
ABSTRACT Purposes: To describe the clinical characteristics and factors associated with keratitis in patients with corneal foreign bodies in Colombia. Methods: This cross-sectional study was based on a clinical records review of patients who had corneal foreign bodies and were admitted to the emergency department between June 2018 and June 2019 in Cali, Colombia. The primary outcome was the presence of keratitis diagnosed based on clinical criteria. Univariate and multivariate logistic regression models were used to identify associated factors. Results: A total of 381 corneal foreign bodies in 372 patients were analyzed (median age, 40.0; interquartile range, 29.0-53.0 years; male, 94.7% (n=352). Ninety-five patients developed keratitis (24.9%, 95% confidence interval [CI] 20.8%-29.5%). In the multivariate analysis, age 30 years (odds ratio [OR] 2.15, 95% CI 1.06-4.36), finding of aqueous flare (OR 2.81, 95% CI 1.39-5.66]), and a foreign body in the peripheral cornea (OR 2.05, 95% CI 1.19-3.50] were associated with an increased risk for keratitis. Sex, time between injury and admission, and corneal edema were not related to keratitis (p>0.05). Conclusion: In Cali, Colombia, a high proportion of keratitis was reported in patients with corneal foreign body. Age, an aqueous flare, and a foreign body in the peripheral cornea were the factors associated with keratitis.
RESUMO Objetivo: Descrever as características clínicas e os fatores associados à presença de ceratite em pacientes com corpos estranhos na córnea em uma população colombiana. Métodos: Trata-se de um estudo transversal baseado na revisão dos registros clínicos de pacientes com corpos estranhos na córnea admitidos em um departamento de emergência em Cali, Colômbia, entre junho de 2018 e junho de 2019. O desfecho primário foi a presença de ceratite diagnosticada através de critérios clínicos. Foram utilizados modelos de regressão logística univariada e multivariada para identificar os fatores associados. Resultado: Neste estudo, foi analisado um total de 381 corpos estranhos na córnea em 372 pacientes (idade média: 40,0 anos, intervalo interquartil: 29,0-53,0; sexo masculino: 94,7% [352 casos]). Noventa e cinco casos desenvolveram ceratite (24,9%, intervalo de confiança de 95% — IC 95%: 20,8%-29,5%). Na análise multivariada, para idade ≤30 anos (razão de chances — RC: 2,15, IC 95%: 1,06-4,36), o achado de flare aquoso (RC: 2,81, IC 95%: 1,39-5,66]) e a presença de corpo estranho na periferia da córnea (RC: 2,05, IC 95%: 1,19-3,50) foram associados a um risco aumentado de ceratite. Sexo, tempo entre a lesão e a internação, e edema da córnea não foram relacionados à ceratite (p>0,05). Conclusão: Há uma proporção elevada de ceratite em casos de corpos estranhos na córnea em Cali, Colômbia. Os três fatores associados à ceratite foram a idade, o achado de flare aquoso e a presença de corpo estranho na periferia da córnea.
RESUMO
Resumen La escritura científica tiene su estructura bien establecida y aceptada por la comunidad académica. El seguimiento adecuado de estas normas implícitas facilita la publicación e interpretación de los resultados de las investigaciones; la estructura adecuada de un artículo científico comprende desde la acertada elección del título, hasta la correcta selección de las referencias. La apropiada redacción del resumen permite capturar la atención del lector, por lo que debe ser cuidadosamente escrito. La introducción debe poner en contexto el cuerpo del conocimiento sobre la investigación que se está reportando y argumentar la necesidad de esta. Los métodos deben describir todos los procesos de investigación que se realizan, para permitir que en cualquier escenario se replique lo que se ha realizado. Los resultados deben ser presentados de forma objetiva, limitándose a resaltar los hallazgos importantes. La discusión permite un contraste de los nuevos hallazgos con lo previamente conocido y cómo esos resultados pueden ser incorporados en el acervo del conocimiento. Todos estos aspectos son discutidos de manera esquemática, siguiendo el estilo IMRD (Introducción, Métodos, Resultados y Discusión) y le permitirán al lector familiarizarse con el método de la escritura de un artículo científico.
Abstract Scientific writing has its well-established structure and it is accepted by the academic community. Proper compliance with these implicit rules makes it easier to publish and interpret the research results. The adequate structure of a scientific paper ranges from the proper choice of title to the correct selection of references. The proper writing of the abstract allows to capture the attention of the reader, so it must be carefully written. The introduction should put into context the body of knowledge about the research being reported and argue the need for it. Methods should describe all research processes to allow replication of what has been done in any setting. Results should be presented objectively, limiting to highlight im- portant findings. Discussion allows contrast of the new findings with what was previously known and how these results can be incorporated into the body of knowledge. All these aspects are discussed following the IMRD format (Introduction, Methods, Results and Discussion) and will allow the reader to become familiar with the method of writing a scientific article.
RESUMO
Objetivo: Describir las características clínicas y el resultado visual de un grupo de pacientes con complicaciones de procedimientos estéticos faciales que acudieron a consulta a la clínica de oftalmología de Cali. Diseño y Métodos: Estudio observacional descriptivo serie de casos. Resultados: Nueve casos, seis mujeres y tres hombres con edad media de 45 años (R: 25-65 años). Seis pacientes con complicaciones vasculares de rellenos faciales. Una obstrucción de la arteria oftálmica, dos de arteria central de la retina y tres de rama arterial. Tres casos de trauma penetrante con aguja durante anestesia para tatuaje palpebral con agudeza visual de PL, CD y NPL y diagnóstico de endoftalmitis, hemorragia vítrea y atrofia óptica, respectivamente, los dos primeros fueron tratados con cirugía. Todos los procedimientos fueron realizados por cosmetólogas. A excepción de un caso, todos tuvieron agudeza visual peor de 20/400 al final del seguimiento. Tres casos fueron NPL. Conclusiones: La pérdida de la visión severa e irreversible es una complicación rara pero devastadora de procedimientos estéticos faciales. Visiones finales peores de 20/400 ocurrieron en 88 % del total de los casos y 33.3% quedan NPL. Debido a que no existe tratamiento efectivo para el embolismo por sustancias diferentes al ácido hialurónico, la principal medida es la prevención.
Objective: To describe the clinical characteristics and visual outcome of a group of patients with complications of facial aesthetic procedures who came to the Cali ophthalmology clinic. Design and Methods: Observational study descriptive series of cases. Results: Nine cases, six women and three men with mean age of 45 years (range: 25-65 years). Six patients with vascular complications of facial fi llings. One of them presented occlusion of the ophthalmic artery, two have occlusion of central artery of the retina and three have occlusion of arterial branch. Three cases of penetrating trauma with a needle during anesthesia for palpebral tattoo with visual acuity of LP, CF and NLP and diagnosis of endophthalmitis, vitreous hemorrhage and optic atrophy respectively, the first two were treated with surgery. Cosmetologists performed all procedures. With the exception of one case, all of the patients had visual acuity worse than 20/400 at the end of follow-up. Three cases were NLP. Conclusions: Severe and irreversible loss of vision is a rare but devastating complication of facial aesthetic procedures. Final worst visions of 20/400 occur in 88% of the total cases and 33.3% are NLPs. Because there is no effective treatment for embolism by substances other than hyaluronic acid, the main measure is prevention.
