Cerebral venous thrombosis in ulcerative colitis.

Cerebral venous thrombosis is a rare complication of ulcerative colitis. We report a case of 29 year old male who developed superior sagittal, left lateral and sigmoid sinus thrombosis secondary to ulcerative colitis. He was successfully treated with low molecular weight heparin and steroids.

The lateralizing significance of version of head and dystonic limb posturing in epileptic seizures.

Several clinical signs have been described for lateralization and localization of seizure focus in complex partial seizures; however, the specificity of each of these has been widely debated upon. The present study was done to evaluate 'dystonic unilateral limb posturing' and 'versive head movements' for lateralization and localization of epileptic foci in patients with intractable partial complex seizures, being investigated with long term Video-EEG monitoring. Fifteen patients with 46 seizures, studied with long term Video EEG, had either one or both of these signs. The video recordings of the clinical behaviour were noted and later compared with the corresponding EEG. Unilateral dystonic limb posturing and versive head movements had good lateralising value in complex partial seizures, suggestive of temporal lobe origin, contralateral to the seizure focus, with a specificity of 87.5% and 86% respectively. In addition, turning of the whole body to one side was associated with a contralateral seizure focus in 100% cases. Appendicular automatisms were found to be of no lateralising significance, as they occurred on either side with equal frequency. These motor phenomena should, therefore, be enquired about in detail, during history taking for lateralization or localization of seizure focus.

Epilepsy surgery in India: All India Institute of Medical Sciences experience.

OBJECTIVES: Surgical treatment of epilepsy should be considered an important alternative to medical therapy. The identification of a suitable candidate, pre-operative evaluation requires a multidisciplinary team. The specific diagnostic studies required depend on the operative strategy and objective of surgical treatment. METHODS: In twenty patients with medically intractable epilepsy, who had clinical evaluation, electroencephalography (EEG), video-EEG monitoring using scalp electrodes, high resolution magnetic resonance imaging (MRI), neuropsychology, single photon emission computed tomography (SPECT) was done to localise the seizure focus. If the investigations were concordant resective surgery was performed. In case of frequent falls, atonic and tonic seizures, with generalised/multifocal discharges on EEG, a callostomy was done. Surgical outcome was assessed using Engel's 4 point scale. RESULTS: In 18 patients the seizure focus was localised, 13 had temporal lobectomy, five extra-temporal resection, and two had callosotomy. Fifteen patients had a follow-up of more than eight months, mean 20.5 (range 8-35 months), 13 had outcome I (seizure free), two had outcome II (occasional seizures), one-outcome III. Three were lost to follow-up and one patient died. There were no major post-operative complications. CONCLUSIONS: Surgical treatment of epilepsy is a safe, effective mode of therapy. Suitable candidates should be identified early and referred to appropriate centres.
