ABSTRACT
Resumen OBJETIVO: Determinar el porcentaje de concordancia del estudio transoperatorio con el diagnóstico definitivo de tumores limítrofes de ovario. MATERIALES Y MÉTODOS: Estudio observacional, transversal, retrospectivo y descriptivo efectuado en el Hospital de Ginecoobstetricia 4 Luis Castelazo Ayala, Ciudad de México, en pacientes operadas entre el 1 de enero de 2018 y el 31 diciembre de 2020 de un tumor abdominopélvico, con examen transoperatorio de tumor limítrofe de ovario. El estudio transoperatorio se evaluó como prueba diagnóstica y el diagnóstico definitivo como patrón de referencia para establecer la concordancia del primero con el diagnóstico definitivo de tumores limítrofes de ovario. RESULTADOS: Se analizaron 68 tumores limítrofes de ovario, entre los diagnosticados en el estudio transoperatorio y el definitivo. Se encontraron 59 casos con diagnóstico definitivo de tumor limítrofe de ovario. La concordancia con el estudio transoperatorio fue de 63.2%. Se sobrediagnosticaron 2 de 68 pacientes (2.9%) y se subdiagnosticaron 23 de 68 (33.8%). CONCLUSIONES: La concordancia obtenida es semejante a lo reportado en la bibliografía internacional. Los tumores mucinosos mayores de 10 cm son subdiagnosticados con mayor frecuencia debido a su extensión.
Abstract OBJECTIVE: To determine the percentage of concordance of the transoperative study with the definitive diagnosis of borderline ovarian tumors. MATERIALS AND METHODS: Observational, cross-sectional, retrospective and des-criptive study performed at the Hospital de Gineco Obstetricia 4 Luis Castelazo Ayala, Mexico City, in patients operated between January 1, 2018 and December 31, 2020 for an abdominopelvic tumor, with transoperative examination of borderline ovarian tumor. The transoperative study was evaluated as a diagnostic test and the definitive diagnosis as a reference standard to establish the concordance of the former with the definitive diagnosis of borderline ovarian tumors. RESULTS: Sixty-eight borderline ovarian tumors were analyzed, between those diagnosed in the transoperative study and the definitive one. We found 59 cases with definitive diagnosis of borderline ovarian tumor. The concordance with the transoperative study was 63.2%. Two of 68 patients (2.9%) were overdiagnosed and 23 of 68 (33.8%) were underdiagnosed. CONCLUSIONS: The concordance obtained is like that reported in the international literature. Mucinous tumors larger than 10 cm are most frequently underdiagnosed due to their extension.
ABSTRACT
BACKGROUND: Brachial artery doppler fluxometry permits to evaluate the endothelial function in a non-invasive way. OBJECTIVE: To know the effect of vasomotor symptoms in brachial artery flux ultrasonographic parameters in Mexican postmenopausal women. MATERIAL AND METHODS: A prospective study was done including postmenopausal women divided into two groups: I) without hot-flushes and II) with hot-flushes. To all them Doppler fluxometry was done. The pulsatility index resistance index and arterial diameter were determined previous and after the hyperemic stimulus. The intensity of vasomotor symptoms (hot-flushes, throbs and sweatings) was determined using an analog visual scale; and the number of each one of them was determined. For statistical analysis Student t test for independent and paired samples was used. Correlation analysis was done between age, time since menopause, hot flushes, throbs and sweating with pulsatility index, resistance index and arterial diameter previous and after hyperemic stimulus. RESULTS: Thirty patients were divided into two groups of 15 women each. No differences were found between the groups neither in age, anthropometric variables, pulsatility index, resistance index nor arterial diameter neither before nor after hyperemic stimulus; only there was a statistically significant increase in arterial diameter after hyperemic stimulus in group I (p < 0.001). In group I a positive correlation was found between age and baseline resistance index and in group II between baseline resistance index and the number of throbs per week. CONCLUSION: Women with hot-flushes have a healthier endothelium.
