Does screening for adverse effects improve health outcomes in epilepsy? A randomized trial.

Objective: To determine whether systematic screening for adverse effects of antiepileptic drugs (AEDs) reduces toxicity burden and improves health-related quality of life in patients with epilepsy.

Methods: Consecutive patients with uncontrolled seizures aged ≥16 years and a high Adverse Event Profile (AEP) score were randomized to 2 groups and followed up for 18 months at 11 referral centers. AEP scores were made available to treating physicians at all visits in the intervention group, but not in the control group.

Validated outcome of treatment changes according to International League Against Epilepsy criteria in adults with drug-resistant focal epilepsy.

Objective: Although many studies have attempted to describe treatment outcomes in patients with drug-resistant epilepsy, results are often limited by the adoption of nonhomogeneous criteria and different definitions of seizure freedom. We sought to evaluate treatment outcomes with a newly administered antiepileptic drug (AED) in a large population of adults with drug-resistant focal epilepsy according to the International League Against Epilepsy (ILAE) outcome criteria.

Methods: This is a multicenter, observational, prospective study of 1053 patients with focal epilepsy diagnosed as drug-resistant by the investigators.

How the cognitive reserve interacts with β-amyloid deposition in mitigating FDG metabolism: An observational study.

This observational study had the aim to assess the interaction between cognitive reserve (CR) and cerebrospinal fluid β-amyloid1-42 (Aβ1-42) in modulating brain [18F]fluorodeoxyglucose positron emission tomography (FDG-PET) metabolism in patients with moderate Alzheimer disease (AD).Twenty-seven patients with probable AD and 25 neurological normal subjects (NNS) entered the study. All participants had an FDG-PET scan, and AD patients also received a lumbar puncture to measure Aβ1-42, 181p-tau, and Tau concentrations.

Early recurrence of Tako-Tsubo cardiomyopathy in an elderly woman with amyotrophic lateral sclerosis: different triggers inducing different apical ballooning patterns.

: We report the case of early recurrence of Tako-Tsubo cardiomyopathy in an elderly woman with amyotrophic lateral sclerosis triggered by different stressors. A first episode with typical apical ballooning was anticipated by an emotional stress; a second, characterized by systolic anterior motion of the mitral valve associated with mitral regurgitation and severe intra-ventricular gradient, was precipitated by surgical stress and hypovolemia. We therefore hypothesize both a possible link between amyotrophic lateral sclerosis and Tako-Tsubo cardiomyopathy, and between different stressors and different Tako-Tsubo patterns.

Weight loss and decubitus duodenal ulcer in Parkinson's disease treated with levodopa-carbidopa intestinal gel infusion.

Apparently, unexplained weight loss is a common symptom experienced by patients affected by Parkinson's disease, especially in those treated by levodopa-carbidopa infusion gel (LCIG) with a poor control of dyskinesias. Weight loss is considered part of gastrointestinal dysfunction seen in patients affected by Parkinson's disease, along with gastroparesis and reduced bowel peristalsis. In patients treated with LCIG, weight loss needs to be accurately evaluated, because of possible underlying life-threatening adverse events, like duodenum decubitus ulcer.

Bilateral putaminal necrosis and bronopol toxicity.

Among alcohols, methanol intoxication is the most frequently associated with cerebral toxicity, causing retinal damage and putaminal necrosis. This consequence is believed to be due to the transformation of methanol into formic acid. We describe the case of a patient who presented with acute impairment of consciousness and tetraparesis after she had been drinking several bottles of a topical antiseptic solution (Lysoform Medical) containing 2-bromo-2-nitro-1,3-propandiol (bronopol) among excipients, in order to lose weight during previous months.

Italian consensus conference on epilepsy and pregnancy, labor and puerperium.

To facilitate an integrated and rational approach to the care of women with epilepsy of childbearing potential, a group of experts appointed by Italian scientific societies in the fields of epileptology, neonatology, pediatrics, neuropediatrics, child neuropsychiatry, obstetrics, and gynecology held a joint meeting in Santa Trada di Cannitello, Reggio Calabria, Italy, on October 15-16, 2004, with the aim of reaching consensus on the optimal management of these women. An ad hoc system for the classification of available published evidence and the opinions of experts was developed and used to grade recommendations on different aspects related to counseling, diagnostic, and treatment issues. The present document summarizes available evidence on the reciprocal interactions between epilepsy, antiepileptic drugs, fertility, contraception, pregnancy, delivery, breastfeeding, and the offspring.

Changes in lamotrigine pharmacokinetics during pregnancy and the puerperium.

To assess changes in the pharmacokinetics of the anti-epileptic drug lamotrigine (LTG) during pregnancy, plasma LTG concentrations at steady-state were determined at different intervals during 11 pregnancies in 10 women with epilepsy stabilized on long-term LTG therapy. In the five pregnancies that could be assessed both during gestation and after delivery, plasma LTG concentrations increased on average by 164% (range +75 to +351%) between the last observation during pregnancy and the puerperium (P < 0.05).

Effects of topiramate and levetiracetam vs placebo on habituation of contingent negative variation in migraine patients.

Migraine is characterized by reduced habituation of multimodal evoked potentials, which in turn reflects an abnormal pattern of cortical excitability. We assessed the effects of a 2-month treatment with topiramate or levetiracetam vs placebo on contingent negative variation (CNV) habituation and amplitude in a cohort of migraine without aura (MO) patients. Forty-five MO patients were selected from a university-based outpatient clinic and randomly assigned to 100mg topiramate or 1000mg levetiracetam or placebo in a double-blind design.
