[Lamotrigine in refractory epilepsy].

INTRODUCTION: Lamotrigine (LTG) is a new antiepileptic drug indicated in all kinds of partial and generalised clonic-tonic seizures, both in monotherapy and polytherapy. Between 20 and 30% of epileptic patients have poor control over their seizures despite adequate treatment. AIMS: We report on our experience regarding the long-term efficacy and tolerability of LTG in refractory seizures. PATIENTS AND METHODS: We conducted a consecutive 10-year study of patients who began LTG therapy following poor control of their seizures, in spite of being treated with two or more antiepileptic drugs in monotherapy or in combination. Both their epidemiological and clinical data were collected for study. We studied the efficacy of the treatment, differentiating between remission (absence of seizures), improvement (reduction>50% of the seizures), inefficacy (reduction<50%), exacerbation (increase in seizures) and its tolerability (side effects and dropout). RESULTS: In all, data was collected from 39 patients, 18 males (46.2%), mean age 30.9 +/- 13.7 years; mean follow up time: 27.6 +/- 23.4 months. 43.7% presented cryptogenic epilepsy, in 28.5% it was symptomatic and in the remaining 28.5% it was idiopathic. EEG readings and neuroimaging scans were pathological in 53.8% and 43.6%, respectively. After beginning therapy with LTG, 33% remained free of seizures, 43.6% improved, in 18.3% it was seen to be ineffective and 5.1% got worse. Dropout rate was 56.4%:23.1% due to insufficient control over the seizures, 17.9% owing to side effects and 15.4% because of non-compliance. CONCLUSION: Treatment with LTG offers a high degree of efficacy in the control of seizures in patients with refractory epilepsy, although it is limited by a high dropout rate.

[Neurosonological findings in the carotid artery in a sample of patients with lacunar infarction].

INTRODUCTION: Carotid stenosis has been reported as being associated to lacunar infarcts (LI) with variable frequency, but the aetiopathogenic relation between them is still subject to some controversy. AIMS: Our aim was to describe the prevalence of carotid disorders in a neurosonological study of a sample of patients with LI. PATIENTS AND METHODS: We analysed the results of the neurosonological study conducted on patients with clinical-radiological criteria of LI who were admitted to our Stroke Unit during the period of study. RESULTS: We studied 140 patients, and results were normal in only 42% of the cases. Stenosis > 50% was found in 10% of the cases and plaque without stenosis in 40.3% of the patients. In patients without plaque there was an increase in the tunica intima-media thickness in 7.2% of the cases. CONCLUSION: In most of the patients with LI there were anomalies in the study of the carotid performed using ultrasound scanning.

[Binocular diplopy as the presentation of a haematoma in the rectus inferior].

INTRODUCTION: The presence of quick onset binocular diplopy makes it essential to carry out a comprehensive differential diagnosis. The most frequent causes in adults include vascular, post-traumatic, tumorous and myopathic pathologies. Yet, to perform a differential diagnosis we also have to take into account less common aetiologies such as demyelinating disease, carotid-cavernous fistulas and Tolosa Hunt syndrome, among others. We report the case of a patient who was admitted to our hospital because she presented an acute onset diplopy secondary to a spontaneous haematoma of the left rectus inferior. CASE REPORT: We describe the case of a 54-year-old female with a history of hypercholesterolemia, who was a smoker and allergic to iodine contrasts and who visited because of an acute onset diplopy accompanied by instability and pain in the left eye. The neurological examination revealed paresis of the extraocular muscles dependent on the left oculomotor nerve with left palpebral ptosis, paresis of the rectus inferior, with no involvement of the pupils. Other results of the exploration were within normal limits. A computerised axial tomography scan of the head showed a haemorrhage in the rectus inferior. Magnetic resonance images of the head revealed an increase in the volume of the left-side rectus inferior with signs of bleeding, and the rest of the complementary explorations were normal. The patient progressed favourably and the diplopy gradually disappeared. CONCLUSIONS: Spontaneous bleeding of the extraocular muscles, although infrequent, must be taken into account in the differential diagnosis of painful ophthalmoplegia with diplopy in patients with no underlying pathology, especially in the absence of other neurological disorders.

[Neurosonological studies in patients over 80 years old].

INTRODUCTION: The link between cardiovascular risk factors and carotid atheromatosis has been shown to be more important in middle aged subjects than in the elderly. AIMS: Our aim was to study the frequency of carotid and intracranial atheromatosis in a population over the age of 80 and to compare the presence of neurosonological anomalies depending on whether the patients have suffered a stroke or not. We also wished to compare the findings according to the sex of the patient. PATIENTS AND METHODS: Patients over the age of 80 were studied at our Neurosonology laboratory using carotid and transcranial Doppler ultrasonography. The patients were analysed according to whether they had suffered an ischemic stroke or not. With regard to the carotid, a distinction was made between normal, non-significant atheromatosis and significant atheromatosis (stenosis > 50%). Intracranially, both the middle cerebral artery (normal, stenosis, microangiopathy and post-stenosis) and the basilar artery (normal, stenosis, microangiopathy and hyperdynamics) were studied. RESULTS: We recorded data concerning 832 patients: 342 males (44.1%), mean age 83.63 +/- 3.25 years, and 527 (63.3%) with stroke. The carotid study was pathological, with a higher frequency in stroke patients (32.1% compared with 41.9%; p = 0.002). The presence of atheromatosis was significantly linked to a higher risk of suffering a stroke and more intensely to its being more severe. Carotid studies were pathological with a higher frequency among males (28.7% compared with 40%; p < 0.001). No significant differences were found intracranially in any of the parameters analysed. CONCLUSIONS: There is a high frequency of carotid atheromatosis in patients over 80 years of age. Regardless of the age, carotid atheromatosis appears even more frequently in patients who have suffered a stroke and in males, and is significantly associated to the risk of suffering a stroke. Intracranially, no differences were found.
