We report a case of placenta percreta diagnosed by ultrasound and color doppler image at the fourteenth week of gestation. Initial approach was a trial of IM methotrexate followed by total hysterectomy, during which was observed a rupture of the uterus with the adherence of the placenta to the posterior region of the bladder. We also present a literature review on the incidence of placenta percreta, etiology, diagnosis, treatment, and complications.

The benefits of surgical treatment for patients with congenital heart disease in relation to pregnancy are still controversial. We studied 48 pregnant women (mean age = 25 years) with surgically-corrected congenital heart diseases (Group 1). This included 15 cyanotic diseases: Fallot's tetralogy (11 cases); Ebstein's anomaly (2 cases); transposition of the great arteries (1 case); and double outlet of the right ventricle (1 case). ⋯ Spontaneous abortion (4 vs. 10 percent), Caesarean deliveries (48 vs. 66 percent) or growth retardation (13 vs. 28 percent) did not present any significant differences between these groups. Surgical treatment in patients with heart diseases is associated with a better maternal and fetal prognosis. Therefore, surgery must be considered when counseling patients with congenital heart diseases.

The red cell distribution width (RDW), and another red cell discriminant function incorporating RDW (MCV2 x RDW/Hgb x 100) were determined in a group of 30 patients with iron deficiency anemia, 30 patients with beta thalassemia trait, and 30 normal subjects. Both RDW and (MCV2 x RDW/Hgb x 100) mean values were significantly higher in iron deficiency anemia than in beta thalassemia trait (p < 0.001). Taking RDW equal or above 21.0 percent among microcytic anemia patients, we identified correctly 90.0 percent of patients with iron deficiency anemia. ⋯ Taking values of (MCV2 x RDW/Hgb x 100) above and below 80.0 percent as indicative of iron deficiency and beta thalassemia trait, respectively, we identified correctly 97.0 percent of those patients in each group. Both sensitivity and specificity were 97.0 percent (IC 95 percent: 0.84-0.99). These results indicated that the red cell discriminant function incorporating volume dispersion (MCV2 x RDW/Hgb x 100) is a highly sensitive and specific method in the initial screening of patients with microcytic anemia and is better than RDW in differentiating iron deficiency anemia from beta thalassemia trait.
