The amino acids L-glutamate and L-aspartate have been shown to be excitatory neurotransmitters in mammalian central nervous systems. Antagonists acting selectively at excitatory amino acid receptors have shown antiepileptic properties in several animal models. We report the results of the first therapeutic trial of the competitive NMDA antagonist, D-CPP-ene (SDZ EAA-494), in eight patients with intractable complex partial seizures. All patients withdrew prematurely because of side-effects, including poor concentration (8), sedation (7), ataxia (6), depression (3), dysarthria (2), amnesia (2) and unilateral choreo-athetosis in a patient with contralateral Sturge-Weber syndrome. Seizures were unchanged in four patients and worse in three. A further patient with apparent improvement in seizures in the first week developed complex partial status epilepticus on withdrawal of DCPP-ene. EEG on treatment (5) or in the immediate post-treatment period (2) showed slowing of background activity and, in five cases, an increase in epileptiform activity. Serum concentrations of DCPP-ene were found to be unpredictable and higher than expected from pharmacokinetic data on normal subjects. There was no clear relationship between serum concentrations and the severity of side-effects. Preliminary experience with DCPP-ene in patients with refractory partial seizures is not promising. Evaluation of related compounds is warranted.

Twenty patients affected by bilateral occipital cortical-subcortical calcification (BOC) are described, 19 (95%) had epilepsy. In 8 of 16 cases studied, intestinal biopsy revealed coeliac disease. Fourteen patients had occipital partial epilepsy with a relatively benign outcome, while 4 patients were affected by a severe form of epilepsy, with very frequent, drug-resistant, generalised and partial seizures with mental deterioration. One patient had a single episode of convulsive status epilepticus at four months of age. The neurological examination was normal in all patients. CT showed flocculo-nodular, cortico-subcortical BOC, without enhancement and without lobar or hemispheric atrophy. MRI was normal. The clinical and neuroimaging features of these patients are different therefore from those with the Sturge-Weber Syndrome. The study confirms a high prevalence of coliac disease in patients with BOC, but the relationship between these two pathologies still needs to be clarified.

Sturge-Weber syndrome (SWS) is a neurocutaneous disorder that is typically associated with progressive neurological deterioration. We describe a 12-year-old girl with SWS who suffered a permanent cerebral insult as the result of a period of protracted status epilepticus. The case illustrates the unique susceptibility of patients with SWS to uncontrolled venous hypertension and emphasises the need for optimal seizure control and preservation of venous outflow. We discuss the relevance of our observations to haemodynamic concepts of neurological decline in SWS.

The term hypomelanosis of Ito (HI) is applied to individuals with skin hypopigmentation following the lines of Blaschko (type 1a of patterns indicative of somatic mosaicism as defined by Happle). Even though originally described as a purely cutaneous disease, subsequent reports of HI have included a 30-94% association with multiple extracutaneous manifestations. The frequency of extracutaneous associations has led many authors to consider HI to be neurocutaneous disorder. We report a male infant with cutaneous hypomelanosis along the lines of Blaschko distributed on the left half of the body who developed status epilepticus. Neuroimaging studies disclosed an angiomatous enlargement of the right choroid plexus and a gyral pattern of cortical and subcortical calcification in the right occipital region. Thus a diagnosis could be made of HI and associated Sturge-Weber syndrome-like leptomeningeal angiomatosis. This previously unreported association lends further support to the consideration of hypomelanosis of Ito as a marker of somatic mosaicism with frequently associated neurologic abnormalities. A relationship between HI and Sturge-Weber syndrome, two neuroectodermal disorders with a genetic mosaicism basis, might be possible due to nonallelic twin-spotting which in the embryologic period would define an abnormal development of neural, vascular, and cutaneous structures.

A three-year-old boy presented with status epilepticus with right hemiconvulsion and complex partial status epilepticus (CPSE) that were preceded by disturbance of consciousness and right hemiplegia just after a traumatic head injury. He was diagnosed as Sturge-Weber syndrome (SWS) because of the presence of a small cutaneous port-wine nevus and the nature of his MRI findings. The nevus was located in the middle of the forehead and was light in color. Intravenous drip infusion of lidocaine was effective for the treatment of CPSE, but the patient has experienced refractory complex partial seizures since then. It has not yet been reported that patients with SWS developed CPSE following head trauma, although it is known that patients with SWS can manifest convulsive status epilepticus. CPSE should be recognized as one of the seizure types of SWS.

High-dose phenobarbital therapy is an effective treatment for refractory status epilepticus in children. The advantages of this therapy include milder adverse effects without limits for maximal phenobarbital levels or doses during the initial phase of treatment. However, little is known about the safety of continuing the treatment. We describe an infant with intractable epilepsy associated with bilateral Sturge-Weber syndrome who became comatose after 1(2/3) months of high-dose phenobarbital treatment. The patient regained consciousness as serum phenobarbital concentration decreased to below 40 microg/mL. The progression and recovery were also documented by electroencephalogram and brainstem auditory evoked potentials. The present case suggests that prolonged high-dose phenobarbital therapy may cause cerebral and brainstem dysfunction in patients with severe cerebrovascular diseases. The underlying baseline metabolic and perfusion deficit related to the disease can precipitate the neurological complication during long-term high-dose phenobarbital therapy.

Hemiplegic migraine (HM) in the setting of Sturge-Weber syndrome (SWS) has been previously described. Here, we report clinical and multimodal imaging data on a 21-year-old man with SWS and HM, who presented during an acute HM attack with a dense left-hemispheric syndrome (expressive aphasia and right sensorimotor hemiplegia), lasting for more than 10 days. Repeated EEGs were without evidence of status epilepticus. Consistent with previous findings in prolonged migraine aura, perfusion computed tomography demonstrated left-hemispheric hyperperfusion on day 7. 18F-FDG positron emission tomography (day 7) revealed left-hemispheric hypermetabolism. After 14 days, the patient was symptom-free and discharged home. Follow-up after 30 days showed normal neurological status. Our observation confirms and reinforces the comorbidity of SWS and HM and shows that prolonged HM attacks are associated with complex changes of both cerebral perfusion and glucose metabolism. A pathophysiological model explaining both the association between SWS/HM and the observed imaging changes is presented.

Sturge Weber Syndrome also called as encephalotrigeminal angiomatosis is a sporadically occurring neurocutaneous syndrome, characterized by vascular malformation with capillary venous angiomas that involve face, choroid of eye and leptomeninges with resulting neurological and orbital manifestations. We hereby report a young unmarried girl who diagnosed as a case of SWS on the basis of Port wine stain since birth, past history of seizures since the age of four years and at this time presented with status epilepticus, mental retardation (I.Q.--30 to 35), EEG abnormality and characteristic imaging findings. This may be a common condition for paediatrician and neurologist but as a physician we usually do not see it that often.

Sturge-Weber syndrome is a rare, sporadic, congenital neurocutaneous syndrome characterized by facial cutaneous vascular malformation, leptomeningeal angioma and eye abnormalities. Seizures develop during the first year of life, may become refractory to multiple anticonvulsants and status epilepticus may develop. A rare subtype of Sturge-Weber syndrome with bilateral facial vascular malformation, unilateral cerebral involvement and neonatal status epilepticus is reported here. Neonatal status epilepticus was successfully controlled with intravenous levetiracetam infusion.

Sturge-Weber syndrome (SWS) is a rare sporadic neurocutaneous syndrome defined by the association of a facial capillary malformation in the ophthalmic distribution of the trigeminal nerve, with ipsilateral vascular glaucoma and vascular malformation of the eye, and a leptomeningeal angioma. SWS is suspected at birth in the presence of facial angioma in the trigeminal nerve area. MRI with gadolinium enhancement and pondered T1, T2, FLAIR and diffusion sequences is today the technique of choice to visualize the leptomeningeal angioma or to suspect it by indirect signs, even before the development of neurological signs, from the first months of life. The prognosis of SWS with leptomeningeal angioma is related to the severity of neurological signs that are absent at birth and develop later in life (epilepsy, hemiparesis, and mental delay). Seizures are usually the presenting neurological symptom. Status epilepticus might inaugurate the epilepsy and remains frequent in infancy. Repetitive seizures are thought to increase the atrophy of brain tissue in regard to the leptomeningeal angioma. Preventive presymptomatic treatment with antiepileptic drugs is often recommended, and parents are trained to use rescue benzodiazepines in case of seizures. After epilepsy onset, in patients intractable to antiepileptic drugs, surgery should be considered.
