This open study reports the use of lamotrigine in 93 adults and children with drug resistant epilepsy. Lamotrigine was used predominantly as add-on therapy and outcome was assessed by the patient, parents and carers and the physician in terms of reduction of seizure frequency, drug side effects, and importantly with this drug, improvement in quality of life. Twenty five of the 93 patients (26.9%) studied were rendered seizure free with the addition of lamotrigine to their therapy. ⋯ Quality of life improvements were especially striking in patients with seizures secondary to brain damage and in the Lennox Gastaut Syndrome. Twenty eight patients ceased lamotrigine, 13 due to lack of effect and the remainder due to side effects. Lamotrigine is a potentially very useful anti-epileptic medication in persons with complex partial seizures, but also in primary generalised epilepsy, the Lennox Gastaut syndrome and especially in those individuals who have seizures subsequent to brain damage.

Course of attention and memory after common whiplash: a two-years prospective study with age, education and gender pair-matched patients.
Attentional functioning and memory of common whiplash patients were evaluated during the first two years after experiencing injury. The study was based on a non-selected sample of 117 whiplash patients referred from primary care and recruited according to a strict injury definition. All patients had a similar socioeconomic background, all being injured in automobile accidents and fully covered by insurance plans. ⋯ In attentional functioning, different levels of improvement were found for symptomatic patients and matched counterparts, with the former showing difficulty at follow-up with tasks of divided attention. Utilized medication and pain intensity could not explain this difference in recovery of attentional functioning between the groups. These findings suggest problems in selective aspects of attentional functioning after common whiplash, which under real life circumstances may explain these patients' cognitive complaints and cause adaptational problems in daily life.

Thalamic stroke: correlation of clinical symptoms, somatosensory evoked potentials, and CT findings.
We studied 18 patients with a single ischemic thalamic lesion, who had somatosensory disturbances and/or central pain in the opposite hemibody, by correlating their clinical symptoms, somatosensory evoked potentials (SEPs), and computed tomography (CT) findings. Patients were divided into three groups: (1) those with somatosensory deficits, central pain, and abnormal SEPs, which comprised two thirds of the patients (classic thalamic pain syndrome), (2) those with somatosensory deficits, no central pain, and abnormal SEPs (analgetic thalamic syndrome), and (3) those with almost normal sense perception, central pain, and normal SEPs (pure algetic thalamic syndrome). CT evidence of a paramedian or anterolateral thalamic lesion might be an indicator for the development of central pain, because these types of infarctions occurred only in patients with the classic thalamic syndrome or the pure algetic thalamic syndrome. The differentiation of the thalamic syndrome into three subtypes is of prognostic value, because patients with a loss of cortical SEPs and a posterolateral ischemic thalamic lesion on the CT scan probably will not exhibit central pain.

Association of Japanese encephalitis virus infection with Guillain-Barré syndrome in endemic areas of south India.
This study is a report of 34 cases of Guillain-Barré syndrome (GBS) observed in Bangalore (South India), an endemic area for Japanese encephalitis virus (JEV) infection. Virological and immunological findings suggested an antecedent and recent JEV infection in 21/34 patients. Nineteen patients among them showed high levels of JEV-specific IgM antibodies in serum and/or CSF, while the viral antigen could be demonstrated in one case and virus isolation from the CSF was successful in one patient. ⋯ Comparison of clinical findings, duration of illness and outcome in GBS patients with evidence of JEV infection and those without did not reveal any differences. Pathological findings in one patient corroborated the association of JEV with GBS. We conclude that, JEV infection may predispose to Guillain-Barré syndrome in endemic areas.

To elucidate whether any relationship exists between genetic polymorphic acetylation and the risk for multiple sclerosis (MS), we determined this polymorphism, using sulphamethazine, in 71 patients with definite MS and in 268 age-matched controls. Thirty-seven patients (52.1%) and 151 controls (56.3%) were classified as slow acetylators (not significant difference). No relation was found between acetylator polymorphism and age at onset of disease in MS patient's group. Our results do not support the existence of any relationship between acetylator polymorphism and the risk for MS.
