[Evaluation of the body mass index, maternal weight gain and ideal weight of women with normal pregnancy]. / Evaluación del índice de masa corporal, ganancia de peso materno y porcentaje de peso ideal en mujeres con embarazos normales.

The objective was to evaluate the body-mass index (BMI), maternal weight gain and the percentage of maternal weight in relation to reference table of weight for height in women with good pregnancy outcome. A total of 250 pregnant women were prospect followed up from week 20 to the end of the pregnancy. Maternal height, (BMI), maternal weight gain at 20 weeks' gestation, the last nearest to delivery, and percentage of maternal weight were recorded. A (BMI) between 19 and 27 was seen in 80% of the women, partial body weight with a range of 4 to 6 kg, total body weight from 7 to 18 Kg, and the range of values of percentage of weight that we obtained was between 89 and 125%. References of weight gain and prepregnancy BMI for a specified population would allow a nutritional assessment of the pregnant women.

[Diabetes mellitus. Exercise and pregnancy]. / Diabetes mellitus. Ejercicio y embarazo.

Based on animals and human studies on the safety of exercise in pregnancy as well as on their results on the disminution of the perinatal morbidity and mortality, the Second International Workshop-Conference on Gestational Diabetes Mellitus (1985) endorsed the concept that pregnant diabetic women with an active lifestyle may continue a program of moderate exercise under medical supervision. The purpose of this review is to establish the principal aspects of the physical exercise prescription for to get their better benefits. Before starting an exercise program all patients should have a complete history and physical examination, with particular attention to identifying the physical health, chronological and gestational ages, type of diabetes mellitus, diabetic control and presence of any long term complications of diabetes, because the all of them depend the type, duration, intensity and frequency of the exercise, as well as, to avoid any risk.

[Autoimmune thrombocytopenia and pregnancy]. / Púrpura trombocitopénica autoinmune y embarazo.

Autoimmune thrombocytopenic purpura PTA, occurs more commonly in women during the reproductive years. Consequently, physicians frequently must manage pregnant patients with PTA. The management of the mother is simplified because an important measure of platelet count, is readily available. However the management of the fetus is more difficult because no definitive maternal treatment to prevent fetal thrombocytopenia has been successful. The performance of percutaneous umbilical blood sampling or fetal scalp sampling allow the determination of fetal platelet before delivery. If a fetal thrombocytopenia of less than 50,000 mm3 is detected, cesarean section is indicated to avoid intracranial hemorrhage in the fetus.

[Preeclampsia in pregnancy. Importance of reclassification]. / Preeclampsia en el embarazo. Importancia de la reclasificación.

It is difficult to determine the etiology of hypertension during pregnancy on the basis of clinical criteria alone. The purpose of the present study is to emphasize the impact of the postpartum reclassification of the hypertensive disorders in gestation. One hundred and fifty eight patients with an initial diagnosis of preeclampsia were prospectively studied. The follow-up included a reclassification of their hypertensive disorder at 4, 8 and 12 weeks postpartum. Such reclassification was based on renal function test and values of blood pressure. Among 158 patients, 118 had an initial diagnosis of preeclampsia during pregnancy, and only in 39 cases (33%) such diagnosis was confirmed postpartum. At the time of reclassification the rest of the patients belonged to the following conditions: gestational hypertension without proteinuria 35%, chronic hypertension 16%, nephropathy (7 with renal biopsy) 11%, and 4% with chronic hypertension and superimposed preeclampsia. There was no significative difference in perinatal morbidity between patients with chronic and gestational hypertension. A total of 10% of perinatal mortality rate was found. We concluded that the reclassification postpartum of the hypertensive disorders in pregnancy is essential to avoid errors in diagnosis and to establish adequate maternal and perinatal outcomes in future pregnancies.
