RESUMEN

BACKGROUND: Musicogenic reflex seizures (MRS) are a rare form of seizures described in patients with temporal lobe epilepsy (TLE), mainly of unknown etiology. Epilepsy with antibodies against glutamic acid decarboxylase (GAD-ab) is a form of autoimmune epilepsy for which no specific semiology has been described. AIM OF THE STUDY: To retrospectively review the incidence of MRS in the general epileptic population and in the series of patients with epilepsy and GAD-ab and to describe its clinical and paraclinical characteristics. METHODS: Patients recorded between January 2010 and January 2016 in the Database of Bellvitge Hospital Epilepsy Unit were reviewed. RESULTS: From a group of 1510 epileptic patients, three reported MRS (0.0019%) (two patients with epilepsy and GAD-ab and one patient with cryptogenic TLE). The incidence of MRS in patients with epilepsy and GAD-ab was 2 of 22 (9%). Both patients had a normal magnetic resonance Imaging (MRI), but FDG-PET showed medial temporal lobe hypometabolism (unilateral or bilateral) in both and also in the insula in one of them. MRS (recorded via video-EEG[electroencephalography] in one patient) arose from the right temporal lobe. CONCLUSIONS: MRS may be a distinctive seizure type in patients with epilepsy and antiGADab. Determination of GAD-ab should be carried out in all cases of MRS, even those with normal structural MRI.

RESUMEN

OBJECTIVE: To explore the long-term effectiveness of rufinamide in managing Lennox-Gastaut Syndrome (LGS), other epileptic encephalopathies, and intractable focal epilepsies in adults and children in routine clinical practice. METHODS: A multicentre, retrospective chart review of patients prescribed adjunctive rufinamide at seven Spanish epilepsy centres, with assessments at six and 12 months. RESULTS: We evaluated data from 58 patients (40 male, age range 7-57 years), 25 of whom were diagnosed with LGS, 12 with other epileptic encephalopathies and 21 of whom were diagnosed with focal epilepsies, mainly frontal lobe. The mean daily rufinamide dose was 32.0 mg/kg (range 12.5-66.7 mg/kg) in children and 24.7 mg/kg (range 5.0-47.0 mg/kg) in adults, and the most commonly used concomitant antiepileptic drugs were levetiracetam and valproate. Rufinamide was discontinued in 25 patients (43.1%) during the 1-year follow-up, and the most common reason was lack of effectiveness (n = 12, 20.7% of total). The frequency of generalized tonic-clonic seizures was significantly reduced from baseline at 6 and 12 months (P = 0.001), both in patients with generalized epilepsies and in patients with focal epilepsies. Significant seizure frequency reduction from baseline was observed at 12 months (P = 0.01) for tonic/atonic seizures and at 6 months (P = 0.001) for focal seizures. Side effects were reported in 21 patients (36.2%): nausea, vomiting and weight loss were most frequent. CONCLUSIONS: Rufinamide was well tolerated and was effective in reducing frequency of generalized tonic-clonic, tonic/atonic and focal seizures in both children and adults with severe refractory epilepsies, primarily LGS.

RESUMEN

BACKGROUND: Palliative techniques such as partial corpus callosotomy (CC) and vagus nerve stimulation (VNS) may be effective for adequate control of seizures in pharmacoresistant patients who are not candidates for resective surgery. OBJECTIVE: The objective of this study was to analyze the efficacy of the combination of these two techniques in patients where the first surgery had not achieved adequate control. MATERIALS AND METHODS: This is a retrospective review of 6 patients with refractory epilepsy in which both types of surgery were performed, CC and VNS. We analyzed variables such as age, sex, age at onset of epilepsy, seizure types, electroencephalogram and magnetic resonance imaging results, and number of pre- and postoperative seizures. RESULTS: Three patients first underwent VNS and then CC, and 3 patients were treated in reverse order. All patients had some improvement after the first surgery, but they continued to experience persistent falls, so a second palliative technique was used. The mean improvement after both surgeries was 89% (90% in patients first receiving CC and 87% in patients who first underwent VNS). CONCLUSIONS: In adequately studied patients who are not optimal candidates for resective surgery, palliative surgery is a choice. The combination of VNS and CC shows good results in our series, although the right order to perform both procedures has not been defined. These results should be confirmed in a larger group of patients.
