Pulmonary hypertension during pregnancy: management of two cases.

Purpose: The aim of this article is to describe two cases of pulmonary hypertension during pregnancy to highlight the major issues associated with the obstetric and anesthesiological management of such patients who, despite the medical advice, decided to continue their pregnancy and gave birth to healthy babies.

Methods And Results: In our first case, there has been the need for a general anesthesia because of the detachment of the placenta, whereas in the second case elective surgery under spinal anesthesia was performed, thus avoiding the anesthesiological and surgical problems associated with an emergency.

Conclusions: Pregnancy is contraindicated in case of pulmonary hypertension, a highly morbid disease affecting young women of childbearing age.

Endogenous interferon-alpha level is increased in hepatitis C virus (HCV)-positive pregnant women.

Background: Mother-to-child transmission of hepatitis C virus (HCV) has been reported in around 5% of cases, and is much more likely to occur in case of coinfection with HIV. However, other cofactors influencing the vertical transmission are still debated.

Aim: To assess the serum concentration of endogenous interferon (IFN) during pregnancy, and its eventual role on the vertical transmission of HCV.

Investigation of endothelin-1 type A receptor gene polymorphism (-231 G > A) in preeclampsia susceptibility.

Objective: Preeclampsia is considered as a multifactorial disorder with a genetic predisposition. Alterations in the endothelin-1 (ET-1) system are considered to take part in triggering the vasoconstriction seen in preeclampsia.

Methods: In order to investigate the possible association of the -231 G > A polymorphism in the endothelin-1 type A receptor gene (EDNRA), previously shown to be associated with other conditions characterized by vasospasm, we examined 77 Caucasian preeclamptic women and 67 matched controls including normotensive subjects without history of thromboembolic event, abnormalities in blood pressure, proteinuria, edema and preeclampsia.

Hypoplastic left heart syndrome with intact atrial septum: case report.

Objectives: Hypoplastic left heart syndrome (HLHS) with an intact atrial septum (IAS) is a rare finding, reported in only 1% of pathologic specimens with hypoplasia of the aortic tract complex. In newborns with left heart obstruction, the existence of an interatrial communication is very important for oxygenated blood to be distributed to the body and to prevent pulmonary congestion. The ability to predict prenatally restriction of the atrial defect may allow earlier surgery to be planned.

Cervical phIGFBP-1 in the evaluation of the risk of preterm delivery.

Background: To evaluate the accuracy of the decidual phosphorylated isoform of insulin-like growth factor binding protein-1 in endocervical secretions to predict premature delivery in symptomatic and asymptomatic pregnant women.

Methods: The study included 332 pregnant women: 109 symptomatic patients (study group) and 223 asymptomatic women (control group). For all women, qualitative and quantitative assessment of the decidual phosphorylated isoform of insulin-like growth factor binding protein-1 in endocervical secretions was carried out, but the quantitative assay was finally performed in 282 of 332.

C-reactive protein in hypertensive disorders in pregnancy.

Hypertension is the most frequent medical complication of pregnancy. A recent report demonstrates the flogistic pathogenesis of pregnancy-induced hypertension. Because C-reactive protein (CRP) is a marker of inflammation, it can be used in the differential diagnosis of hypertensive disorders of pregnancy.

Ballantyne syndrome: a case report.

Ballantyne syndrome (also called mirror syndrome or triple edema) describes the unusual association of fetal and placental hydrops with maternal preeclampsia. This is a case report illustrating a 37-year-old patient who was referred to our clinics at 28 weeks of gestation (wg) because of fetal hydrothorax. On examination, the woman did not show signs of preeclampsia.

Recent progress in the therapeutic management of pre-eclampsia.

Pre-eclampsia is a pregnancy-specific syndrome of unknown aetiology, observed in 3 - 5% of all pregnancies, associated with pathological vascular lesions in multiple organs, activation of the coagulation system, and maternal multisystemic and fetal complications. Clinically, pre-eclampsia is characterised by the onset of hypertension, proteinuria and oedema, usually beginning in the third trimester. Conventionally, antihypertensive agents are the main pharmacological treatment.

Efficacy of AT in pre-eclampsia: a case-control prospective trial.

Pre-eclampsia is an extremely severe condition. It is associated with vasospasm, activation of the coagulation system and abnormal haemostasis. In pre-eclamptic patients increased plasmatic concentrations of fibronectin, laminin, von Willebrand factor (VWF) and endothelin are observed.

Acute hepatic failure in pregnancy.

Severe liver dysfunction in late pregnancy is an unusual but dramatic event because it can progress very rapidly to fulminating disease and also because two lives, that of the mother and foetus, are involved. We report a descriptive study of a pregnant woman presenting with severe liver dysfunction.

Prenatal diagnosis of vein of Galen aneurysmal malformations.

Vein of Galen aneurysmal malformations are rarely seen intracranial malformations. They represent less than 1% of the cerebral arteriovenous malformations. Prenatal diagnosis of an arteriovenous fistula malformation may be achieved by real-time and Doppler sonography with color flow imaging, by identifying dilated veins and arteriovenous shunts with turbulent flow.

Anhydramnios and maternal thrombocytopenia after prolonged use of nimesulide.

Prostaglandin synthesis inhibition have been proposed as an effective alternative to prevent preterm labour. This case report shows a pregnancy with anhydramnios and maternal thrombocytopenia, as side effects of the nimesulide therapy.

Intra-hepatic cholestasis of pregnancy in hepatitis C virus infection.

Background: Aims of this study were to investigate whether hepatitis C virus infection influences the incidence and natural history of intrahepatic cholestasis of pregnancy (ICP) and whether ICP has different characteristics in hepatitis C virus (HCV) positive women from ICP in HCV negative women.

Methods: A prospective study for the prevalence of the HCV infection and for the incidence of ICP was carried out in the 5840 patients admitted to the Prenatal Department of Padua University, Italy, between January 1996 and January 1999. Testing was done for HCV by the enzyme linked immunosorbent assay (ELISA 3), recombinant immuno blot assay (RIBA 3) and polymerase chain reaction (PCR).
