[Maternal metabolic diseases related to pre-pregnancy overweight and obesity in mexican women with high risk pregnancy]. / Enfermedades metabólicas maternas asociadas a sobrepeso y obesidad pregestacional en mujeres mexicanas que cursan con embarazo de alto riesgo.

INTRODUCTION: Pre-pregnancy obesity has been proposed as a risk factor related to gestational diabetes and hypertensive disorders during pregnancy. OBJECTIVES: Identify pregnancy related diseases associated with pre-pregnancy obesity as a risk factor ina high risk preganancy patient population. METHODS: 600 patients whose pre-pregnancy obesity had been assessed as a high risk factor were included in the study. The means, standard deviation, median, interquartile intervals, Pearson and Spearman correlation and logistic regression to estimate risk with the odds ratio and 95% confidence intervals were calculated. RESULTS: The mean pre-pregnancy body mass index was 29.59 ± 6.42 kg/m2. The mean for recommended pregnancy weight gain was 2.31 ± 1.03 kg, but the mean of real weight gain was 8.91 ± 6.84 kg. A significant correlation between pre-pregnancy obesity and family history of diabetes mellitus (p=0.000), systemic hypertension (p=0.003), cardiac diseases (p=0.000), dyslipidemia (p=0.000) and obesity (p=0.000) was identified. Pre-pregnancy obesity was identified as a risk factor for the development of gestational diabetes (OR: 1.95; IC95%: 1.39 to 2.76; p=0.000) in this kind of patient. DISCUSSION AND CONCLUSION: 75% of high risk pregnancy women in a high specialty hospital in West Mexico are overweight or obese when they become pregnant. These are risk factors in the development of gestational diabetes.

[Sacrococcygeal teratoma: report of a case and review of the literature]. / Teratoma sacrococcígeo: reporte de un caso y revisión de la bibliografía.

Sacrococcygeal teratoma is the most common tumor in infants. About 80% of these tumors are types 1 and 2, and are unlikely to cause metastases whose incidence is 10% in the neonatal period, against nearly 100% at the age of 3 years. These tumors can acquire huge and contain large proportions depriving blood flows to the developing fetus, the tumor hypervascularity generates a hyperdynamic state in the fetus, and that as the tumor grows, it increases its flow to behave as a short circuit and to be similar to that of the lower limbs of the fetus, increasing venous return and cardiac output, heart failure causing fetal and maternal eclampsia.
