RESUMEN

Resumo Fundamento Os limiares de corte para a "relação do ciclo completo de repouso" (RFR) oscilam em diferentes séries, sugerindo que as características da população podem influenciá-los. Da mesma forma, foram documentados preditores de discordância entre a RFR e a reserva de fluxo fracionado (FFR). O Estudo RECOPA, mostrou que a capacidade diagnóstica está reduzida na "zona cinzenta" da RFR, tornando necessária a realização de FFR para descartar ou confirmar isquemia. Objetivos Determinar os preditores de discordância, integrar as informações que eles fornecem em um índice clínico-fisiológico: a "RFR Ajustada", e comparar sua concordância com o FFR. Métodos Usando dados do Estudo RECOPA, os preditores de discordância em relação à FFR foram determinados na "zona cinzenta" da RFR (0,86 a 0,92) para construir um índice ("RFR Ajustada") que pesaria a RFR juntamente com os preditores de discordância e avaliar sua concordância com a FFR. Resultados Foram avaliadas 156 lesões em 141 pacientes. Os preditores de discordância foram: doença renal crônica, cardiopatia isquêmica prévia, lesões não envolvendo a artéria descendente anterior esquerda e síndrome coronariana aguda. Embora limitada, a "RFR Ajustada" melhorou a capacidade diagnóstica em comparação com a RFR na "zona cinzenta" (AUC-RFR = 0,651 versus AUC-"RFR Ajustada" = 0,749), mostrando também uma melhora em todos os índices diagnósticos quando foram estabelecidos limiares de corte otimizados (sensibilidade: 59% a 68%; especificidade: 62% a 75%; acurácia diagnóstica: 60% a 71%; razão de verossimilhança positiva: 1,51 a 2,34; razão de verossimilhança negativa: 0,64 a 0,37). Conclusões Ajustar a RFR integrando as informações fornecidas pelos preditores de discordância para obter a "RFR Ajustada" melhorou a capacidade diagnóstica em nossa população.

Abstract Background Cutoff thresholds for the "resting full-cycle ratio" (RFR) oscillate in different series, suggesting that population characteristics may influence them. Likewise, predictors of discordance between the RFR and fractional flow reserve (FFR) have been documented. The RECOPA Study showed that diagnostic capacity is reduced in the RFR "grey zone", requiring the performance of FFR to rule out or confirm ischemia. Objectives To determine predictors of discordance, integrate the information they provide in a clinical-physiological index, the "Adjusted RFR", and compare its agreement with the FFR. Methods Using data from the RECOPA Study, predictors of discordance with respect to FFR were determined in the RFR "grey zone" (0.86 to 0.92) to construct an index ("Adjusted RFR") that would weigh RFR together with predictors of discordance and evaluate its agreement with FFR. Results A total of 156 lesions were evaluated in 141 patients. Predictors of discordance were: chronic kidney disease, previous ischemic heart disease, lesions not involving the anterior descending artery, and acute coronary syndrome. Though limited, the "Adjusted RFR" improved the diagnostic capacity compared to the RFR in the "grey zone" (AUC-RFR = 0.651 versus AUC-"Adjusted RFR" = 0.749), also showing an improvement in all diagnostic indices when optimal cutoff thresholds were established (sensitivity: 59% to 68%; specificity: 62% to 75%; diagnostic accuracy: 60% to 71%; positive likelihood ratio: 1.51 to 2.34; negative likelihood ratio: 0.64 to 0.37). Conclusions Adjusting the RFR by integrating the information provided by predictors of discordance to obtain the "Adjusted RFR" improved the diagnostic capacity in our population. Further studies are required to evaluate whether clinical-physiological indices improve the diagnostic capacity of RFR or other coronary indices.

RESUMEN

Los dispositivos intrauterinos no están exentos de complicaciones y al igual que cualquier otro cuerpo extraño implantado en el organismo puede migrar a otra región. Presentación de caso: paciente femenina con antecedentes de implantación de un dispositivo intrauterino (T de cobre) en su área de salud hace seis meses, acude al servicio de cirugía refiriendo dolor intermitente en fosa iliaca izquierda y bajo vientre de varios meses de evolución, además de proctodinia. En el ultrasonido abdominal y ginecológico no se observó la presencia del dispositivo intrautero pero sí hacia la proyección anexial izquierda, en el rayos x de pelvis antero posterior se comprobó la imagen radiopaca del dispositivo intrauterino hacia fosa ilíaca izquierda. Conclusiones: se intervino quirúrgicamente encontrándose dispositivo intrauterino de localización intraovárica y trompa de Falopio de ese lado inflamada y adherida al ovario, realizándosele salpingectomía y ooforectomía izquierda. La paciente evolucionó favorablemente sin complicaciones postoperatorias, se egresó a los cinco días después de terminado el tratamiento antibiótico de la sala de cirugía(AU)

The intrauterine devices are not exempt of complications and as any other foreign body implanted in the organism can migrate to another area. Case presentation: a female patient with a history of an implant of an intrauterine device (copper T) in her health area six months ago comes to the surgery service with an intermittent pain in the left iliac fossa and low abdomen with several months of evolution, besides proctodinia. In the abdominal and gynecological ultrasounds there was no presence of the intrauterine device but towards the left iliac fossa. Conclusions: She had a surgery, finding the intrauterine device of intraovaric and phallopians trump of that swollen and adhered side to the ovary, carrying out left salpingectomy and oophorectomy. The patient evolved favorably without post-operatory complications. She was released five days after finished the antibiotic treatment of the surgery ward(AU)

RESUMEN

Fundamento: El hemangioma rectal es una enfermedad infrecuente que afecta a adultos jóvenes. El signo de presentación más frecuente es el sangrado rectal indoloro. Presentación del caso: Paciente femenina de 43 años con antecedente de rectorragias de causa no precisada desde hace tres años, a pesar de estudios endoscópicos que fueron normales. Se diagnostica el caso como una posible colitis ulcerativa; la paciente continuó con sangrado rectal que le produjo anemia severa y tenesmo intenso, por lo que se decide tratamiento quirúrgico. El estudio anatomopatológico informó la presencia de un hemangioma cavernoso del recto. Este caso es novedoso por lo infrecuente a nivel mundial. Conclusiones: La paciente evolucionó favorablemente y sin complicaciones postoperatorias (AU)

Background: Rectal hemangioma is a rare disease that affects young adults. The most common presenting sign is painless rectal bleeding. Case presentation: 43 year old female patient with a history of rectal bleeding of an undefined cause for three years, despite endoscopic studies were normal. The case is diagnosed as a possible ulcerative colitis. The patient continued with rectal bleeding which caused her severe anemia and intense tenesmus, therefore, a surgical treatment was applied. The pathological study confirmed the presence of a cavernous hemangioma of the rectum. This case is novel as it is rare worldwide. Conclusions: The patient improved and had no postoperative complications

RESUMEN

Se realizó un estudio sobre el manejo quirúrgico de enfermedades proctológicas en consulta externa del hospital Universitario Camilo Cienfuegos con el objetivo de enumerar las intervenciones realizadas, presentar las complicaciones mas frecuentes en cuanto al manejo quirúrgico y conocer el ahorro económico y la repercusión social en 2000 pacientes operados en consulta externa. Resultados: la hemorroidectomia y la fisurectomia fueron las técnicas mas realizadas con un 40 por ciento y 31.3 por ciento respectivamente, solo se presentaron complicaciones en un 3 por ciento de nuestros enfermos. El manejo quirúrgico de estas enfermedades en consulta externa tiene un significativo impacto económico pues en 2000 pacientes operados se ahorró al hospital por concepto de días/pacientes 167 700 pesos y por concepto de día cama 152.760. Conclusiones: el manejo quirúrgico en consulta de estas enfermedades tiene una importante repercusión económica y una apreciable aceptación social pues el 98 por ciento de los enfermos estuvo de acuerdo con esta modalidad(AU)

A study was made on the surgical handling of proctological diseases in external consultation of the Camilo Cienfuegos University Hospital with the objective of enumerating the interventions carried out, to present the most frequent complications as to the surgical handling and to know the economic saving and the social repercussion in 2000 patients operated in external consultation. Results: haemorrhoidectomy and fissurectomy were the techniques most carried out with a 40 percent and a 31.3 percent, respectively. Complications were present in only a 3 percent of our patients persons. The surgical handling of these illnesses in external consultation has a significant economic impact because in 2000 operated patients you saving to the hospital for concept of días/pacientes 167 700 pesos and for concept by day bed 152.760. Conclusions: the surgical handling in consultation of these illnesses has an important economic repercussion and an appreciable social acceptance because 98% of the sick persons agreed with this modality(AU)
