We have studied the course of early neonatal period in the newborns with delayed intrauterine development syndrome (DIUDS). Clinical neurological and electroencephalographic (EEG) studies of 208 neonates with DIUDS have been performed. Control group consisted of 234 newborns with normal height-weight values. Newborns with DIUDS exhibited hypoxy-ischemic encephalopathy with prevailing general cerebral symptoms in 64%; respiratory distress syndrome in 33.1%, partial pulmonary atelectasis--12.9%, and intrauterine infection--8.1%. Most frequently hypoxy-ischemic encephalopathy was registered in premature babies with DIUDS--78.2% (18% in control group), in cases with history of mother's extragenital pathology--in 72.4% (9% in control group), in 66% in cases with pre-eclampsia (4% in control group), and in 50% in both cases of perinatal infection and anemia of pregnancy (23% and 10% in control group, respectfully). Clinical-neurological and electro-encephalographic data of the newborns is in correlation with severity of DIUDS. Results of the electro-encephalographic study can be useful in assessment of degree of the central neural system disorder and evaluation of its functional condition.

Posterior reversible encephalopathy syndrome is a rare complication generally associated with headache and acute changes in blood pressure. We present a case of posterior reversible encephalopathy syndrome where diagnosis was delayed because the patient also had preeclampsia and an inadvertent dural puncture, both associated with headache. The clinical challenge and the need for prompt diagnosis and treatment are emphasized.

Just after Caesarean section for twin pregnancy and feto-pelvic dysproportion, a woman presented severe headaches and arterial hypertension, then blurred vision, then generalised seizures. There were no oedematous syndrome, proteinuria was negative, ASAT were 1.5 N and platelet count was 120,000/mm(3). Cerebral CT-scan was normal. Posterior reversible encephalopathy syndrome (PRES) was diagnosed on MRI. A second MRI performed at day 9 showed complete regression of cerebral lesions, while patient was taking anti-hypertensive and antiepileptic drugs. PRES has to be evoked in post-partum central neurological symptoms, even in absence of classical sign of pre-eclampsia, like proteinuria. PRES and eclampsia share probably common physiopathological pathways. There management and prognosis seems identical.

Focal neurologic deficits in the parturient must be rapidly assessed and treated to minimize damage to both mother and child. The following case report features a patient presenting with visual loss, mental status changes, and severe preeclampsia, diagnosed as posterior reversible encephalopathy syndrome. This syndrome manifests radiographically as symmetric hypodensities of the posterior gray and white matter, and is usually reversible with prompt treatment.

Posterior reversible encephalopathy syndrome (PRES) is associated with a specific disorder of cerebrovascular autoregulation of multiple etiologies. This syndrome had been subsequently described in numerous medical conditions, including hypertensive encephalopathy, pre-eclampsia and the use with immunosuppressive drugs. Here, we report a child suffering from Langerhans cell histocytosis developing into PRES following immunosuppressive therapy. Symptoms and neuroimaging abnormalities were complete resolution subsequent to the withdrawal of cyclosporine. Although PRES is rarely seen among children, it should always be considered in the differential diagnosis of acute neurological illness, especially undergoing immunosuppressive therapy.

Posterior reversible encephalopathy syndrome (PRES) is a transient clinical neuroradiological entity characterized by clinical signs and symptoms including hypertension, generalized seizure activity, altered mental status, headache, and vision changes; along with characteristic findings on head computed tomography or magnetic resonance imaging scan. Albeit a rare condition, PRES is most commonly reported in the literature in association with obstetric patients suffering from pre-eclampsia or eclampsia. In the acute setting, it is important to recognize the characteristics of PRES and immediately treat the inciting conditions: the patient's hypertension and seizures. Although this condition is usually transient and completely reversible, ischemic injury and irreversible damage have been reported. In the event of early and effective treatment, cognitive function may be completely restored. The following case report reviews a pregnant patient who presented to the Emergency Department with generalized seizure activity and a clinical picture characteristic of PRES. The case demonstrates how appropriate treatment in the acute setting allows complete restoration of cognitive function in the long term.

Abnormal liver tests occur in 3%-5% of pregnancies, with many potential causes, including coincidental liver disease (most commonly viral hepatitis or gallstones) and underlying chronic liver disease. However, most liver dysfunction in pregnancy is pregnancy-related and caused by 1 of the 5 liver diseases unique to the pregnant state: these fall into 2 main categories depending on their association with or without preeclampsia. The preeclampsia-associated liver diseases are preeclampsia itself, the hemolysis (H), elevated liver tests (EL), and low platelet count (LP) (HELLP) syndrome, and acute fatty liver of pregnancy. Hyperemesis gravidarum and intrahepatic cholestasis of pregnancy have no relationship to preeclampsia. Although still enigmatic, there have been recent interesting advances in understanding of these unique pregnancy-related liver diseases. Hyperemesis gravidarum is intractable, dehydrating vomiting in the first trimester of pregnancy; 50% of patients with this condition have liver dysfunction. Intrahepatic cholestasis of pregnancy is pruritus and elevated bile acids in the second half of pregnancy, accompanied by high levels of aminotransferases and mild jaundice. Maternal management is symptomatic with ursodeoxycholic acid; for the fetus, however, this is a high-risk pregnancy requiring close fetal monitoring and early delivery. Severe preeclampsia itself is the commonest cause of hepatic tenderness and liver dysfunction in pregnancy, and 2%-12% of cases are further complicated by hemolysis (H), elevated liver tests (EL), and low platelet count (LP)-the HELLP syndrome. Immediate delivery is the only definitive therapy, but many maternal complications can occur, including abruptio placentae, renal failure, subcapsular hematomas, and hepatic rupture. Acute fatty liver of pregnancy is a sudden catastrophic illness occurring almost exclusively in the third trimester; microvesicular fatty infiltration of hepatocytes causes acute liver failure with coagulopathy and encephalopathy. Early diagnosis and immediate delivery are essential for maternal and fetal survival.

Posterior reversible encephalopathy syndrome (PRES) is a neurotoxic state coupled with a unique CT or MR imaging appearance. Recognized in the setting of a number of complex conditions (preeclampsia/eclampsia, allogeneic bone marrow transplantation, organ transplantation, autoimmune disease and high dose chemotherapy) the imaging, clinical and laboratory features of this toxic state are becoming better elucidated. This review summarizes the basic and advanced imaging features of PRES, along with pertinent features of the clinical and laboratory presentation and available histopathology. Many common imaging/clinical/laboratory observations are present among these patients, despite the perception of widely different associated clinical conditions.

Posterior reversible encephalopathy syndrome (PRES) is a neurotoxic state accompanied by a unique brain imaging pattern typically associated with a number of complex clinical conditions including: preeclampsia/eclampsia, allogeneic bone marrow transplantation, solid organ transplantation, autoimmune diseases and high dose cancer chemotherapy. The mechanism behind the developing vasogenic edema and CT or MR imaging appearance of PRES is not known. Two theories have historically been proposed: 1) Severe hypertension leads to failed auto-regulation, subsequent hyperperfusion, with endothelial injury/vasogenic edema and; 2) vasoconstriction and hypoperfusion leads to brain ischemia and subsequent vasogenic edema. The strengths/weaknesses of these hypotheses are reviewed in a translational fashion including supporting evidence and current available imaging/clinical data related to the conditions that develop PRES. While the hypertension/hyperperfusion theory has been most popular, the conditions associated with PRES have a similar immune challenge present and develop a similar state of T-cell/endothelial cell activation that may be the basis of leukocyte trafficking and systemic/cerebral vasoconstriction. These systemic features along with current vascular and perfusion imaging features in PRES appear to render strong support for the older theory of vasoconstriction coupled with hypoperfusion as the mechanism.

Our understanding of cerebral palsy (CP) in term infants is hindered by its low incidence and sporadic presentation. Many of these CP cases enter litigation, and a focused review of medicolegal consultations provides an opportunity to better understand the pathogenesis of these cases. In this study complete clinical and pathologic data from 158 cases of CP complicating singleton pregnancies after 36 weeks of gestation were prospectively collected over a 10-year period extending from 1998 to 2008. A hierarchical system was used to separate cases into the following 5 groups: (1) clinical/sentinel events (20%), (2) severe large fetoplacental vascular lesions (34%), (3) placental lesions indicative of chronic placental dysfunction (23%), and (4) placental lesions indicative of subacute/chronic adaptation to hypoxia (15%). The remaining 8% (group 5) of cases were idiopathic. Common to all subgroups was clinical and/or pathologic evidence of umbilical cord obstruction, which was observed in 63% of cases. The following clinical features significantly differed among subgroups. Group 1 had less maternal obesity and more cases involving multicystic encephalopathy. Group 2 had increased oligohydramnios, cerebral edema, nucleated red blood cell counts greater than 10 000/mm(3), hypoglycemia, pulmonary hypertension, and cardiac dysfunction. Group 3 had more preeclampsia and, together with group 2, more infants with a low ponderal index. Group 5 had a higher prevalence of positive family history of neurodevelopmental disorders. In conclusion, infant cases subject to litigation related to CP following term birth can be separated into distinct clinicopathologic subgroups with only a small number lacking either clinical/sentinel events or placental evidence of subacute or chronic in utero stress.
