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.

The common neurological manifestations of pre-eclampsia include headache, confusion, and visual disturbance; while isolated abducens nerve palsy in pre-eclampsia is very rare. We report one case of a severe pre-eclampsia with abducens nerve palsy at 39 weeks' gestation. There was no specific pathology, except hypertension, and the palsy resolved spontaneously.

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.

1. Information regarding the use of continuous i.v. administration of nitroglycerine as an antihypertensive agent in the management of pre-eclampsia is scarce. In the present study, i.v. nitroglycerine or sublingual nifedipine were administered to 32 women with severe pre-eclampsia who were being managed with controlled plasma volume expansion and MgSO(4) loading and maintenance doses. Maternal blood pressure and heart rate responses, fetal heart rate responses and perinatal fetal-maternal adverse effects were evaluated using classical parametric and non-parametric data analysis and data modelling by mixed models. 2. An important hypotensive response was observed in both groups, although this reponse was greater, faster and exhibited less variability (more precision) in the nitroglycerine-treated group. Heart rate also increased in both the nitroglycerine- and nifedipine-treated groups (4.6 +/- 4.4 vs 8.6 +/- 5.3 b.p.m., respectively), although the increase in the nifedipine-treated group was almost twofold that in the nitroglycerine-treated group. There were no significant changes in fetal heart rate in response to vasodilator therapy. The frequency of perinatal fetal-maternal adverse effects was similar in both groups at 40% and the adverse effects observed included flushing, headache, palpitations and nausea. 3. In conclusion, i.v. infusion of nitroglycerine is an effective, safe and alternative therapy for severe pre-eclampsia.

A 35-year-old woman, gravida 5 para 3, presented to the emergency department 9 days after a cesarean delivery with a new-onset headache, hypertension, and hyperreflexia. Formal urinalysis did not demonstrate proteinuria. Computed tomography of the brain demonstrated bilateral parietal subarachnoid hemorrhages. The patient was subsequently transferred to a tertiary care hospital where she underwent magnetic resonance imaging and computed tomographic angiography that were not suggestive of intracerebral aneurysm, arteriovenous malformation, sinus thrombosis, or angiopathy. The patient was treated with nimodipine and was successfully discharged without any neurologic sequelae or continued hypertension. This case illustrates the potential for presumed postpartum preeclampsia to mask other serious entities, such as intracranial hemorrhage.

We conducted a retrospective study of the management and outcome for eclampsia patients in the intensive care unit (ICU) of National hospital, Abuja between November 2001 and April 2005 (42 months). The patients' case files and ICU records were used to extract the necessary data. During the study period, there were a total of 4857 deliveries, with 5051 total births (including multiple births) and 4854 live births. Forty eclamptics were admitted to the ICU, giving an ICU admission rate of 8.2/1000 live births. The records of two patients were incomplete. The average age of the patients was 28.4 years (range 17-4 years). Six patients (15.8%) were booked and 32 (84.2%) were not. The average duration of stay in ICU was 5 days. Twenty patients (52.6%) had antepartum eclampsia, 12 (31.6%) had postpartum eclampsia and six (15.8%) presented with intrapartum eclampsia. Twenty-nine (76.3%) gave birth via caesarean section and nine (23.7%) delivered per vagina augmented by oxytocin infusion. Seventeen (45%) received mechanical ventilation; 20 (53%) received oxygen via nasal prongs, nasal catheters or variable performance facemask. One patient (2%) did not receive oxygen therapy. All the patients were admitted postpartum. There were 11 maternal deaths, giving a case fatality rate of 29%. There were five (45.4%) deaths due to haemolysis, elevated liver enzymes and low platelet count syndrome and two (18.2%) due to disseminated intravascular coagulation. The remaining deaths were due to cerebrovascular accident (9.1%), lobar pneumonia (9.1%), acute renal failure (9.1%) and multiple organ failure (9.1%). All patients were admitted postpartum. This fatality rate is higher than that detailed in the reports reviewed in this study. Early referral of eclamptics or at risk patients to a tertiary care institution may help reduce morbidity and mortality. In addition, early referral to a facility providing basic essential obstetric care or comprehensive essential obstetric care is also important. Another important factor is the correct diagnosis of pre-eclampsia during antenatal and postpartum care by screening, noting blood pressure levels, performing urinalysis for protein and asking about warning signs such as headache, blurred vision, epigastric pain, etc.

Preeclampsia, a serious hypertensive complication of pregnancy characterized by new-onset hypertension and proteinuria after midpregnancy, is a multisystem disorder that often involves the central nervous system. Neurologic signs and symptoms include hyperreflexia, headaches, visual disturbance, seizures, and cerebral hemorrhage. Eclampsia-new-onset seizures in the setting of preeclampsia-usually occurs before or within 48 hours of delivery, but can present as late as 1 month postpartum (late postpartum eclampsia). Magnesium sulfate is the drug of choice to prevent and treat eclampsia, a recommendation validated through large, randomized, and placebo-controlled trials. This review describes the pathogenesis, clinical features, and treatment of eclampsia, focusing on recent observations regarding roles of circulating antiangiogenic factors in the pathogenesis of the neurologic complications of eclampsia.

Eclampsia is a complication of preeclampsia and is characterized by the appearance of grand mal seizures and/or coma, in the absence of any other neurological abnormalities. Neither focal neurological deficit nor prolonged coma tends to develop following a crisis. Eclampsia should therefore lead us to consider other clinical entities that may require special treatment. We report the case of a pregnant woman who presented total bilateral loss of vision following a grand mal seizure. The patient was subsequently diagnosed with reversible posterior leukoencephalopathy syndrome, which has clinical and radiologic manifestations linked to several causes, such as hypertensive encephalopathy, eclampsia, kidney failure, and immunosuppressant therapy. The syndrome involves headache, altered states of consciousness, changes in vision (including blindness), and seizures; these symptoms generally coincide with a rapid increase in blood pressure. Diagnosis requires neuroimaging, and the typical finding is edema in the posterior zones of the brain hemispheres. The most widely accepted hypothesis concerning the pathophysiologic mechanism underlying this syndrome is failure of cerebral autoregulation with development of vasogenic edema. The prognosis is good and the alterations usually resolve completely with appropriate treatment, which is the same as for the management of eclampsia, with strict monitoring of blood pressure.

We report the clinical-radiological case of a 25 year-old female patient who developed reversible posterior leukoencephalopathy syndrome (RPLS) in the postpartum period, without evidence of preeclampsia-eclampsia or chronic arterial hypertension. RPLS is associated with diverse clinical entities including eclampsia. Ten days after giving birth, the patient presented with clinical symptoms of headache, elevated blood pressure and seizures. Reversible vasogenic oedema affecting the white matter in the posterior regions was the characteristic finding in magnetic resonance imaging (MRI) of the brain. Although the prognosis is favourable, treatment needs to be early and aggressive, with rapid control of the convulsions and arterial hypertension, with the aim of preventing ischemia and cerebral infarct from developing. There is a need to be highly alert and to consider the diagnosis of RPLS in women presenting with convulsions and other neurological symptoms in postpartum.

A retrospective study of 68 eclamptic women who received Magnesium sulphate at Koshi Zonal Hospital were analyzed during a one year period (2006-2007 AD). Maternal conditions at admission, associated complications in mothers and babies, delivery outcomes and cause of death were also studied in each case. There were 5240 deliveries during the period of analysis. Of which 4976 were live births, pregnancy induced hypertension was 0.89% (47), 0.74% (39) presented with pre-eclampsia, 0.30 (16) cases with severe pre-eclampsia and 0.43 (23) cases with mild pre-eclampsia. During this period 1.3% (68) of eclampsia presented to the hospital. Of which 67.7% presented with ante-partum eclampsia, 22.1% with intrapartum eclampsia and 10.3% with post partum eclampsia. Majority of women (63.2%) were between 20-25 years of age, while teenage pregnancy contributed 30.88% of eclamptic cases. The diastolic blood pressure was >110 mm of Hg in 45.6% of cases, 90-110 mmHg in 50% of cases and in 4.4% the it was <90 mmHg. 94.1% presented to the hospital in an unconscious state, 79.4% of eclamptic women received the full dose of magnesium sulphate (initial loading plus maintenance dose), while rest failed to receive the full dose. Nine women with severe pre-eclampsia received magnesium sulphate as a prophylactic measure. 17.7% women had home delivery, one patient left against medical advice and one was referred to a tertiary care center. Caesarian Section (Lower Segment) was performed in 35.2% of cases, 30.8% had normal vaginal deliveries and 5.8% had pre term delivery. About 69.6% babies were born alive, 8.7% were still births, 11.6% were neonatal deaths and 4.4% of babies had to be admitted to the neonatal intensive care. Eclamptic women stayed less than one week in the hospital in majority of cases (64.7%), between 1-2 weeks in 32.4% and more than two weeks in 2.9%. Maternal complications included decreased urinary output, pulmonary edema in three cases; chest and wound infection two cases each; post partum psychosis, vulval haematoma, severe headache one case each. There were seven maternal deaths during this period and eclampsia contributed to one of the deaths. Eclampsia is a major cause of maternal and perinatal morbidity and mortality in our setup. Magnesium sulphate is an excellent drug of choice in management of eclampsia and pre-eclampsia. Wider coverage of pre-natal care, timely referral and optimal management of cases of eclampsia with magnesium sulphate in hospitals are key issues to prevent mortality/morbidity associated with it.
