Seizure control and treatment in pregnancy - Observations from the EURAP Epilepsy Pregnancy Registry
No full textObjective: To analyze seizure control and treatment in pregnant women with epilepsy. Methods: Seizure control and treatment were recorded prospectively in 1,956 pregnancies of 1,882 women with epilepsy participating in EURAP, an international antiepileptic drugs (AEDs) and pregnancy registry. Results: Of all cases, 58.3% were seizure-free throughout pregnancy. Occurrence of any seizures was associated with localization-related epilepsy (OR: 2.5; 1.7 to 3.9) and polytherapy (OR: 9.0; 5.6 to 14.8) and for tonic-clonic seizures, with oxcarbazepine monotherapy (OR: 5.4; 1.6 to 17.1). Using first trimester as reference, seizure control remained unchanged throughout pregnancy in 63.6%, 92.7% of whom were seizure-free during the entire pregnancy. For those with a change in seizure frequency, 17.3% had an increase and 15.9% a decrease. Seizures occurred during delivery in 60 pregnancies (3.5%), more commonly in women with seizures during pregnancy (OR: 4.8; 2.3 to 10.0). There were 36 cases of status epilepticus ( 12 convulsive), which resulted in stillbirth in one case but no cases of miscarriage or maternal mortality. AED treatment remained unchanged in 62.7% of the pregnancies. The number or dosage of AEDs were more often increased in pregnancies with seizures (OR: 3.6; 2.8 to 4.7) and with monotherapy with lamotrigine (OR: 3.8; 2.1 to 6.9) or oxcarbazepine (OR: 3.7; 1.1 to 12.9). Conclusions: The majority of patients with epilepsy maintain seizure control during pregnancy. The apparently higher risk of seizures among women treated with oxcarbazepine and the more frequent increases in drug load in the oxcarbazepine and lamotrigine cohorts prompts further studies on relationships with pharmacokinetic changes. Risks associated with status epilepticus appear to be lower than previously reported
Transient "sicca syndrome" during phenobarbital treatment.
No full textEven after the introduction of new antiepileptic drugs, phenobarbital continues to be largely used in the treatment of epilepsy. We report the case of a 59-year-old woman with focal seizures with secondary generalization, treated with phenobarbital with normal serum levels. After thirty days she showed Sjogren-like symptoms, which resolved after the replaced of phenobarbital with oxcarbazepine. Although many antiepileptic drugs are known to induce autoimmune disorders, a "Sicca Syndrome" has never been reported as an adverse effect of phenobarbital. We think this case report leads to take into consideration the possibility of a drug-induced disorder whenever patients treated with barbiturates develop symptoms suggestive of Sjogren's Syndrome
Supratentorial neurenteric cyst associated with a intraparenchymal subependymoma
No full textNeurenteric cyst is a rare developmental lesion that very infrequently is localised supratentorially. Intraparenchymal subependymoma is an even more rare benign tumour. The authors report the case of a 45-year-old gentleman with a background of drug resistant epilepsy. An MRI was performed which showed a left frontal cystic lesion with a solid component. Histopathology confirmed a type C neurenteric cyst associated with an intraparenchymal subependymoma. Following enlargement of the lesion and worsening of symptoms he was referred to our institution for further management. A frontotemporal craniotomy was performed for excision of the lesion but recurrence occurred within 1 year. The lesion was further excised and 19 months post re-excision the patient is seizure free with no evidence of recurrence on MRI
Quantitative analysis of Lamotrigine in plasma and tablets by planar chromatography and comparison with liquid
No full textA method using planar chromatography (PC) was developed for determining lamotrigine (LTG; 3,5-diamino-6-[2,3-dichlorophenyl]-1,2,4-triazine) in human plasma and tablets. LTG was extracted with acetonitrile in the presence of sodium carbonate. 3,5-Diamino-6-(2-methoxyphenyl)-1,2,4-triazine was used as internal standard, The detection limit was 0.27 mu g/mL plasma and the recovery from human plasma fortified with various concentrations of LTG was 91.3 +/- 3.4%. Interference from other common antiepileptic agents was checked. Results obtained with the PC method were compared with those obtained by a method using liquid chromatography (LC) for analysis of plasma and with methods using LC and UV for assay of tablets
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Transient periodic lateralised epileptiform discharges (PLEDs) following internal carotid artery stenting
No full textBackground. Periodic lateralised epileptiform discharges (PLEDs) are EEG patterns consisting of periodic or pseudoperiodic unilateral, focal or hemispheric epileptiform discharges at a rate of 1-2 Hz. PLEDs may be triggered by acute brain injuries or systemic metabolic changes such as fever, hyperglycaemia or electrolyte imbalance and may result in disturbance of consciousness and/or neurological deficits. Case report. A 58-year-old female with a history of focal epilepsy and deep brain haematoma presented with acute change in awareness, associated with EEG evidence of PLEDs, three days after a left internal carotid artery stenting procedure. Clinical examination, laboratory testing and MRI were unchanged with respect to pre-stenting investigations. Conclusion. In this patient, PLEDs may have been triggered by local haemodynamic changes due to reperfusion after stenting in a previously damaged brain area
