Uric Acid in Pregnancy: New Concepts.

The relationship between hyperuricemia and hypertensive disorders is well established; however, until today, the role of uric acid in the clinical course of severe preeclampsia has not been elucidated. Some recent studies suggest that at the time of presentation, subjects with severe preeclampsia frequently have significantly elevated serum uric acid levels, and that the degree of elevation correlates with the severity of the maternal syndrome and fetal morbimortality. In this chapter, we present our workgroup experience.

[Toxic epidermic necrolysis].

Background: Toxic epidermal necrolysis is a dermatological disease that evolves with an elevated mortality. Our objective was to show the utility of a nonconventional treatment for toxic epidermal necrolysis in place of conventional treatment where the mortality is <50 %. With this suggested treatment, mortality is 0 %.

[Thrombotic microangiopathy and intravascular hemolysis in pregnancy-induced hypertension. The lie of HELLP syndrome].

We reviewed the literature regarding pregnancy-induced hypertension and its relation with thrombotic microangiopathy and intravascular hemolysis (TMIH). In the present work we described the background, frequency, mortality, clinical picture, classification, diagnosis, complications and treatment. In addition, we analyzed Weinstein's report of 1982, and we concluded that the reported data of the HELLP syndrome is not conclusive because the presence of TMIH is not demonstrable in his group of patients.
