ABSTRACT
Objective: The aim of the study was to investigate whether the accuracy of ultrasound estimates of fetal weight (EFW) was dependent on maternal obesity.Study design: A prospective cross-sectional study of 1064 singleton pregnant women classified according to body mass index (BMI) into two categories: normal (BMI < 25 kg/m2, n = 863) and obese (BMI ≥ 35 kg/m2, n = 201) was conducted. EFW were calculated using Hadlock's formula, and the difference between EFW and the actual birthweight (absolute percent error) was analyzed in both groups. Spearman's correlation was used to assess the relationship between ultrasound performance (absolute error), maternal BMI, and actual birth weight.Results: Median absolute error of sonographic EFW was 5.90 and 6.47% for the normal and obese groups, respectively (p .38). A correlation between EFW and birth weight (BW) was found in both groups, r = 0.755 (p < .001) and r = 0.753 (p < .001), respectively. The correlation between absolute error, maternal BMI, and fetal birth weight was poor.Conclusions: Maternal obesity is unrelated to the accuracy of sonographic EFW, and regardless of maternal or fetal size, ultrasound is currently an accurate method of prediction for both obese and normal weight pregnant women.

Objetivo: Revisar las características que tiene el cáncer de mama (CM) en la mujer joven. Material y métodos: Para ello, se hace una exhaustiva revisión bibliográfica, indicando los factores etiológicos, los métodos diagnósticos y las opciones de tratamiento existentes, con mención especial a circunstancias que pueden concurrir en estas pacientes, tales como la menopausia temprana, la pérdida de fertilidad, el embarazo tras CM y el CM durante la gestación. Resultados: Destacan que el CM en la mujer joven es muy infrecuente, aunque se está constatando un aumento en su frecuencia. Es de mayor tamaño y con márgenes positivos, lo que le confiere una mayor agresividad y una mortalidad más alta. Para su diagnóstico, más difícil que en la mujer mayor, tiene gran importancia el triple test (mamografía, ecografía y biopsia) y sus opciones de tratamiento son las mismas que en las mujeres de más edad. Conclusiones: El CM en la mujer joven tiene unas características especiales que lo diferencian, en algunos aspectos, al CM que se diagnostica en la mujer de más edad (AU)
Objective: To review the characteristics of breast cancer in young women. Material and methods: The scientific literature was reviewed, indicating the etiological factors, diagnostic methods and treatment options, with special reference to the factors that can concur in young patients such as premature menopause, loss of fertility, pregnancy after breast cancer and breast cancer during pregnancy. Results: Importantly, breast cancer in young women is very rare but is on the increase. Tumors are larger in young women and have positive margins, making the disease more aggressive and leading to higher mortality. Diagnosis is more difficult than in older women and the triple test (mammography, ultrasound and biopsy) is of great importance. Treatment options are the same as in older women. Conclusions: Breast cancer in young women shows certain characteristics that differentiate it in some respects from breast cancer diagnosed in older women (AU)
