Seven cases of SLE with concomitant neurological syndromes are reported. In 2 cases brain stroke with right-sided hemiplegia and aphasia developed, in the remaining cases brain-stem stroke with subarachnoid haemorrhage, progressive hemiparesis and signs of intracranial hypertension, chorea, status epilepticus in terminal uraemia were observed. In one case myasthenia coexisted. Severe neurological syndromes were preceded by signs of involvement of other organs and in most cases by low-grade signs of central nervous system involvement. Treatment with corticosteroids and immunosuppressants resulted in significant improvement without complete remission. A retrospective survey of clinical material showed that modern therapeutic methods have improved the prognosis in systemic lupus erythematosus independently of central nervous system involvement.

In order to study spatial interactions during low magnesium induced epileptiform activity, changes in extracellular potassium concentration ([K+]0) and associated slow field potentials (f.p.'s) were recorded in thin rat temporal cortex slices (400 microns) containing the neocortical temporal area 3 (Te3), the entorhinal cortex (EC) and the hippocampal formation with the dentate gyrus, area CA3 and CA1 and the subiculum (Sub). The epileptiform activity was characterized by short recurrent epileptiform discharges (40 to 80 ms, 20/min) in areas CA3 and CA1 and by interictal discharges and tonic and clonic seizure like events (SLE's) (13-88s) in the EC, Te3 and Sub. While interictal discharges occurred independent of each other in the different subfields, the three areas became synchronized during the course of a SLE. The EC, Te3 and Sub all could represent the "focus" for generation of the SLE's. This initiation site for SLE's sometimes changed from one area to another. The characteristics of the rises in [K+]0 and subsequent undershoots were comparable to previous observations in in vivo preparations. Interestingly, rises in [K+]0 could start before actual onset of seizure like activity in secondarily recruited areas. The epileptiform activity could change its characteristics to either a state of recurrent tonic discharge episodes or to a continuous clonic discharge state reminiscent of various forms of status epilepticus. We did not observe, in any of these states, active participation by area CA3 in the epileptiform activity of the EC in spite of clear projected activity to the dentate gyrus. Even after application of picrotoxin (20 microM), area CA3 did not actively participate in the SLE's generated in the entorhinal cortex. When baclofen (2 microM) was added to the picrotoxin containing medium, SLE's occurred both in the entorhinal cortex and in area CA3, suggesting that inhibition of inhibitory interneurons by baclofen could overcome the "filtering" of projected activity from the entorhinal cortex to the hippocampus.

We report on a 10-year-old girl with systemic lupus erythematosus who presented in status epilepticus as the only manifestation of central nervous system involvement. MRI of the brain showed diffuse gray and white matter lesions which almost completely resolved after treatment with methylprednisolone. MRI findings in this child are similar to those in adults with diffuse clinical manifestations. The study is essential in the initial evaluation of patients suspected of central nervous system lupus.

We describe a 36-year-old man with antiphospholipid antibody syndrome complicated by cerebral hemorrhage. In December 1991 he was brought to another hospital with sudden onset of left hemiparesis and status epilepticus. He had been well previously. A CT scan and MRI showed a cerebral hematoma located in the right frontoparietal region. Twelve days later he was transferred to our hospital. Although a CT scan, MRI, and cerebral angiography were repeated, they did not reveal any abnormality regarding an etiology. Only persistently abnormal finding in laboratory studies was positive for lupus anticoagulant and anticardiolipin antibody, i.e. antiphospholipid antibodies. There was no serological evidence of SLE or other autoimmune diseases. Stereotactic biopsy of the hematoma wall and scalp artery showed no abnormality. Based on above findings we conclude that antiphospholipid antibodies have played an important role for the hemorrhage. Antiphospholipid antibody syndrome should be considered in a case of an unexplained cerebral hemorrhage especially in a young and normotensive patient.

Systemic lupus erythematosus (SLE) frequently involves the central nervous system (CNS) and, in fact, epileptic manifestations may be one of the earliest symptoms of SLE. These early occurrences of epilepsy, however, can easily be misdiagnosed as indication of pure epileptic syndrome when the SLE diagnosis is still largely incomplete. We present a young girl who developed myoclonic photosensitive seizures at the onset of the illness, erroneously diagnosed as manifestation of a "pure" epileptic syndrome. Shortly after the onset of an anticonvulsant therapy (lamotrigine), there was a remarkable impairment of the general clinical condition: at that time a diagnosis of SLE was made and a specific treatment began. However, the seizures persisted and evolved toward status epilepticus which needed pentobarbitone therapy in an intensive care unit (ICU). After recovery, the girl gradually got better and during the 23 months of follow-up she received only corticosteroid therapy and did not experience seizures nor SLE relapses.

Neurologic complications of systemic lupus cerebritis are not as well known in children as in adults. Twenty-five children with neurologic complications were identified after reviewing the hospital medical records of 86 children with systemic lupus erythematosus. Seven children (28%) had neurologic symptoms at the time of initial diagnosis of systemic lupus erythematosus; median time between diagnosis of systemic lupus erythematosus and onset of neurologic complications was 1 month (range 0-5 years). Seizures were the most common neurologic symptoms overall, but headaches were the most frequent neurologic manifestation in children without a previous diagnosis of systemic lupus erythematosus. Sixteen children had seizures, and 12 children had seizures as the initial central nervous system involvement. Almost all children who developed seizures had an established diagnosis of systemic lupus erythematosus; only one child had seizures that led to the diagnosis of systemic lupus erythematosus. No patient had status epilepticus, and, in general, seizures were not difficult to control. In six children, headache was the initial symptom of central nervous system involvement. Five children had lupus cerebritis, three children had stroke, and two had isolated cranial neuropathies. Chorea was seen in only two cases, and three children had pseudotumor cerebri. Treatment with high-dose intravenous methylprednisolone led to a good response in 18 children; cyclophosphamide was required in 6 patients and plasmapheresis in 1 child. Outcome was generally good, although one child developed fulminant cerebritis with intracranial hypertension and died.

The purpose of this case report is to describe the clinical, electroencephalographic and neuroimaging findings from a woman with systemic lupus erythematosus presenting with complex partial status epilepticus (CPSE) of neocortical temporo-parieto-occipital origin. The patient experienced complex visual hallucinations that initially were attributed to treatment with corticosteroids; however, an electroencephalogram (EEG) demonstrated the epileptic aetiology of her symptoms. CPSE should be considered as a possible cause of altered mental status in lupus. An urgent EEG is essential to make an accurate diagnosis.

Non convulsive status epilepticus is a heterogeneous condition consisting of very different electroclinical syndromes. It is difficult to make the diagnosis and identify common factors among patients. We report two cases with an unusual presentation. A 31 years old woman having discoid lupus presented with a prolonged exogenous psychosis that lasted two and half months, associated to echolalia. After the episode the patient remained with a severe frontal syndrome that could be the consequence of a non convulsive status epilepticus. A 60 years old woman with an epilepsy diagnosed at the age of 30, presented with recurrent episodes of aphasia. During one of these crises, the electroencephalogram showed continuous epileptiform activity.

A 52-year-old previously healthy woman was admitted to our hospital for status epilepticus in November 1999. She had not taken oral contraceptives. After treatment with intravenous diazepam and phenytoin, she did not develop seizures anymore. When she became alert, there was a mild left hemiparesis. Lumbar puncture showed an opening pressure of 145 mm H2O, and the cerebrospinal fluid was acellular. Cranial MR imaging demonstrated thrombosis of the superior sagittal sinus and fresh infarction in the right frontal lobe. Plasma fibrinogen, fibrin degradation product, and prothrombin fragment 1 + 2 levels were elevated. Proteins S and C activities and anti-thrombin III levels were within the normal range. Lupus anticoagulant and anti-cardiolipin antibody were negative. She was treated with continuous heparin infusion for ten days and with oral warfarin thereafter. Six months after the first admission, platelet count became more than 400 x 10(3)/microliter. In July 2002, she developed slowly progressive monoplegia of the left arm. Cranial MR imaging demonstrated patent superior sagittal sinus, fresh infarction in the right parietal lobe, and old small infarction in the right corona radiata. The patient was maintained on warfarin and 100 mg of aspirin thereafter. In September 2002, platelet count was 737 x 10(3)/microliter. Bone marrow examination showed increased megakaryopoiesis with normal erythroid and myeloid series and no chromosomal aberrations. Serum C-reactive protein and iron levels were in the normal range. An abdominal ultrasound demonstrated mild splenomegaly. Thus, we made a diagnosis of essential thrombocythemia (ET). ET causes thrombotic events in the course of the disease at a rate of 7% per year. Cerebral infarction is not uncommon, but occurrence of cerebral sinus thrombosis has been rarely reported. Recently, several cases have been reported in which cerebral infarction was the first manifestation of ET even with platelet counts lower than 600 x 10(3)/microliter. To our knowledge, there have been no reported cases of ET presenting with cerebral venous sinus thrombosis. Platelet count should be monitored in the patients with venous sinus thrombosis of undetermined etiology.

We describe a woman with systemic lupus erythematosus who had complex partial status epilepticus as the sole epileptic manifestation. The patient presented with a confusional state, initially considered to be psychotic in nature, due to SLE. However, the EEG demonstrated the epileptic etiology of her symptoms. In patients with lupus presenting with prolonged episodes of confusion and behavioural disturbance, an EEG should be performed, whenever possible during the episode, even in the absence of a previous history of epilepsy.
