RESUMEN
Introduction: Chronic wounds represent a frequent cause of consultation for plastic and reconstructive surgeons. The use of epidermal culture stands out because they provide complete epithelialization, adequate aesthetic-functional results, and no morbidity for the patient. Epifast® is a pre-manufactured cultured epidermal allograft derived from the amplification in vitro of human keratinocytes. Materials and Methods: A prospective longitudinal multicenter study was carried out in four chronic wound reference centers, which were in charge of plastic and reconstructive surgery services. For a standardized wound bed preparation, the protocol synthesized by the acronym "TIME" was used. At the end of the "TIME" protocol, the pre-fabricated allograft was applied and removed 7 days after its application. Results: A total of 133 patients with diagnosis of chronic wound were included in the study. The median age was 69.3 ± 13.6 years. The most common comorbidity found was diabetes mellitus type 2 in 71.4% of the patients (n = 95) and systemic arterial hypertension in 60.2% of the patients (n = 80). The most frequent location of chronic wounds was seen in the lower extremity with 45.1% (n = 60). The mean duration for it to close was 46 ± 14 days, in which they closed within the first 3 months in 93% (n = 125) of the cases. About 91.7% (n = 122) of the wounds achieved total closure. Conclusion: Cultured epidermal allograft, combined with a meticulous technique and an adequate selection of patients, represents a safe and effective tool for chronic wounds.
RESUMEN
OBJETIVO: Evaluar la exactitud diagnóstica del Índice de Riesgo de Malignidad II (IRM II) en 100 pacientes con diagnóstico de masa anexial. MÉTODO: En una muestra de 100 pacientes con diagnóstico de masa anexial se cuantificaron variables demográficas y se aplicó el IRM II. Mediante una tabla 2 × 2 se obtuvieron la sensibilidad, la especificidad, el valor predictivo positivo, el valor predictivo negativo y la exactitud diagnóstica, y se compararon con el resultado histopatológico. RESULTADOS: El IRM II con resultado positivo se presentó en el 73.1% (52 pacientes) de los casos con resultado histopatológico maligno y en el 26.9% de aquellos con resultado histopatológico benigno. Presenta una sensibilidad en la prueba del 73.1%, una especificidad del 70.8%, un valor predictivo positivo del 73.2% y un valor predictivo negativo del 70.8%. La exactitud diagnóstica es del 72%. CONCLUSIONES: El IRM II es una herramienta de cribaje con aceptable desempeño diagnóstico para normar la conducta, como referir a un centro especializado o solicitar estudios más específicos en pacientes con diagnóstico de masa anexial por sospecha de malignidad. OBJECTIVE: Evaluate the usefulness of the Malignancy Risk Index II (MRI II) using diagnostic accuracy variables in 100 patients diagnosed with adnexal mass. METHOD: In a sample of 100 patients with a diagnosis of adnexal mass, demographic variables were quantified and MRI II was applied. The sensitivity, specificity, positive predictive value, negative predictive value, and diagnostic accuracy were obtained using a 2 × 2 table and compared with the histopathological result. RESULTS: MRI II with positive result was presented in 73.1% (52 patients) with malignant histopathological result and in 26.9% of patients with benign histopathological result. It presents a sensitivity in the test of 73.1%, a specificity of 70.8%, positive and negative predictive value of 73.2 and 70.8%, respectively. Diagnostic accuracy of 72%. CONCLUSIONS: MRI II is a screening tool with acceptable diagnostic performance to regulate behavior, such as referring to a specialized center or requesting more specific studies in patients diagnosed with adnexal mass due to suspected malignancy.
