Anticonvulsants do not suppress long-term potentiation (LTP) in the rat hippocampus
1991
Long-term potentiation (LTP) of population spikes in the CA1 area of rat hippocampus was induced by tetanic stimulation of stratum radiatum in slices kept submerged in a perfusion chamber. Addition of the two antiepileptic drugs phenytoin or the diazepine midazolam to the medium did not significantly alter this phenomenon within 22 min after the tetanus. The early enhancement (post-tetanic potentiation, PTP) was reduced only by phenytoin. Therefore an interaction of these drugs with N-methyl-D-aspartate (NMDA) receptors and LTP induction is unlikely.
Synthesis, resolution, stereochemistry, and molecular modeling of (R)- and (S)-2-acetyl-1-(4’-chlorophenyl)-6,7-dimethoxy-1,2,3,4-tetrahydroisoquinol…
2007
Abstract Recently we identified ( R , S )-2-acetyl-1-(4′-chlorophenyl)-6,7-dimethoxy-1,2,3,4-tetrahydroisoquinoline ( 6 ) as a potent non-competitive AMPA receptor antagonist able to prevent epileptic seizures. We report here the optimized synthesis of compound 6 , its resolution by chiral preparative HPLC, and the absolute configuration of ( R )-enantiomer established by X-ray diffractometry. The biological tests of the single enantiomers revealed that higher anticonvulsant and antagonistic effects reside in ( R )-enantiomer as also suggested by molecular modeling studies.
Low-level laser therapy and anesthetic infiltration for orofacial pain in patients with fibromyalgia : a randomized clinical trial
2018
Background To compare the analgesic effect of anesthetic infiltration of lidocaine 2% and low-level laser therapy (LLLT) by GaAlAs into tender points of patients with orofacial pain and fibromyalgia (FM). Material and Methods A randomized clinical trial was performed with adults (N=66) that were allocated into two groups (1:1): Group A received LLLT irradiation by Diode Laser GaAlAs (780nm) with expositions twice a week during six weeks and Group B was treated with anesthetic infiltration of lidocaine 2% without vasoconstrictor once a week for four weeks. The pain assessment included the Visual Analogic Scale (VAS) and tenderness to palpation. Results No dropout and adverse effect was obser…
Modulatory effects of nitric oxide-active drugs on the anticonvulsant activity of lamotrigine in an experimental model of partial complex epilepsy in…
2007
Abstract Background The effects induced by administering the anticonvulsant lamotrigine, the preferential inhibitor of neuronal nitric oxide synthase 7-nitroindazole and the precursor of NO synthesis L-arginine, alone or in combination, on an experimental model of partial complex seizures (maximal dentate gyrus activation) were studied in urethane anaesthetized rats. The epileptic activity of the dentate gyrus was obtained through the repetitive stimulation of the angular bundle and maximal dentate gyrus activation latency, duration and post-stimulus afterdischarge duration were evaluated. Results Either Lamotrigine (10 mg kg-1) or 7-nitroindazole (75 mg kg-1) i.p. administration had an ant…
Rufinamide in children and adults with Lennox-Gastaut syndrome: first Italian multicenter experience
2010
This is the first multicenter Italian experience with rufinamide as an adjunctive drug in children, adolescents and adults with Lennox-Gastaut syndrome. The patients were enrolled in a prospective, add-on, open-label treatment study from 11 Italian centers for children and adolescent epilepsy care. Forty-three patients (26 males, 17 females), aged between 4 and 34 years (mean 15.9 ± 7.3, median 15.0), were treated with rufinamide for a mean period of 12.3 months (range 3-21 months). Twenty patients were diagnosed as cryptogenic and 23 as symptomatic. Rufinamide was added to the baseline therapy at the starting dose of 10mg/kg body weight, evenly divided in two daily doses and then increased…
Survey on treatments for primary headaches in 13 specialized juvenile Headache Centers: The first multicenter Italian study
2017
Abstract Aim The purpose of this retrospective multicenter study was to evaluate the use and the self-perceived efficacy and tolerability of pharmacological and non-pharmacological treatments in children and adolescents with primary headaches. Methods Study of a cohort of children and adolescents diagnosed with primary headache, consecutively referred to 13 juvenile Italian Headache Centers. An ad hoc questionnaire was used for clinical data collection. Results Among 706 patients with primary headaches included in the study, 637 cases with a single type of headache (migraine 76% – with and without aura in 10% and 67% respectively; tension-type headache 24%) were selected (mean age at clinic…
Effects on executive functions of antiepileptic monotherapy in pediatric age.
2020
Abstract Objectives Cognitive abilities and executive functions in children and adolescents are important indicators of quality of life as well as academic and social achievements. Cognitive and executive functioning are often impaired in patients with epilepsy and can be exacerbated by seizures and antiseizure drugs. The aim of our observational retrospective study was to assess executive functioning in patients with pediatric epilepsy, currently taking a single antiseizure medication. Materials and methods Records of 172 children and adolescents aged between 6 and 18 years (mean age = 12 ± 3.4 years) with newly diagnosed epilepsy who had not yet commenced an antiepileptic treatment were i…
The safety and efficacy of add-on levetiracetam in elderly patients with focal epilepsy: A one-year observational study
2011
Abstract Purpose The long-term safety and efficacy of levetiracetam (LEV) was evaluated as add-on therapy in focal epilepsy patients ( n =491) aged at least 65 years who failed at least one monotherapy. Methods Patients ( n =491) with focal epilepsy treated with at least one antiepileptic drug in monotherapy with insufficient seizure control were included in this prospective open-label study. The recommended LEV dose range was 1000–3000mgperday. Follow-up visits were done approximately after 3, 6 and 12 months. Safety and efficacy was analysed based on all patients who received LEV (safety population, n =491) and all patients who were seen at all visits and completed the trial (per protocol…
Short-Term Neurodevelopmental Outcome in Term Neonates Treated with Phenobarbital versus Levetiracetam: A Single-Center Experience
2019
Background. Phenobarbital (PB) has been traditionally used as the first-line treatment for neonatal seizures. More recently, levetiracetam (LEV) has been increasingly used as a promising newer antiepileptic medication for treatment of seizures in neonates. Objectives. The aim of our study was to compare the effect of PB vs. LEV on short-term neurodevelopmental outcome in infants treated for neonatal seizures. Method. This randomized, one-blind prospective study was conducted on term neonates admitted to the Neonatal Intensive Care Unit of S. Bambino Hospital, University Hospital “Policlinico-Vittorio Emanuele,” Catania, Italy, from February 2016 to February 2018. Thirty term neonates with s…
Cognitive-behavioral screening in elderly patients with new-onset epilepsy before treatment
2014
Objectives Cognitive comorbidity at epilepsy onset reflects disease severity and provides a baseline estimate of reserve capacities with regard to the effects of epilepsy and its treatment. Given the high incidence of epilepsy at an older age, this study analyzed objective and subjective cognition as well as quality of life in elderly patients with new-onset focal epilepsy before initiation of anti-epileptic treatment. Materials and methods A total of 257 untreated patients (60–95 years of age) with new-onset epilepsy underwent objective assessment of executive function (EpiTrack) and performed subjective ratings of cognition (Portland Neurotoxicity Scale) and quality of life (QoL; QOLIE-31…
