1/140. phenytoin-associated thrombocytopenia in a toddler.Hematologic side effects are rare side effects of treatment with phenytoin. We report a 2-year-old girl who developed reversible thrombocytopenia following treatment with phenytoin. thrombocytopenia as a side effect of phenytoin treatment has usually been reported in adults and generally occurs 2 to 4 weeks after initiation of therapy. In our case, the thrombocytopenia developed on the 11th day of therapy and resolved 5 days after discontinuation of the phenytoin.- - - - - - - - - - ranking = 1keywords = initiation (Clic here for more details about this article) |
2/140. Lamotrigine associated with insomnia.PURPOSE: To review the incidence of lamotrigine (LTG)-associated insomnia in an adult tertiary care epilepsy outpatient clinic. methods: The records of all patients who had received LTG were reviewed to identify patients who had experienced insomnia after introduction of this drug. patients were included if they had experienced a sleep disturbance of sufficient severity to require a discontinuation of LTG or a dose reduction. RESULTS: Among 109 patients exposed to LTG, seven (6.4%) had a sleep disturbance of a severity to required a change in therapy. The descriptions of the sleep disturbance were similar among the patients, and the LTG-induced insomnia appeared to be dose dependent. Unlike the few previous descriptions of LTG-induced insomnia in the literature, no factors predisposing to this adverse effect were identified. CONCLUSIONS: The results of this retrospective review suggest an association between LTG and intolerable insomnia in a small proportion of patients. physicians should inquire about sleep disturbances in patients treated with LTG.- - - - - - - - - - ranking = 297.98192061733keywords = sleep, insomnia (Clic here for more details about this article) |
3/140. Possibilities of non-pharmacological conservative treatment of epilepsy.This study set out to assess the effect of non-pharmacological conservative (NPC) interventions as alternatives to antiepileptic pharmacotherapy. A prospective follow-up cohort study was conducted in an outpatient seizure clinic of a referral center for epilepsy. Twenty-five patients (nine males, 16 females) aged 16-45, with at least two well-described epileptic seizures, were included who had rejected antiepileptic pharmacotherapy. Twelve had idiopathic generalized epilepsy, 11 had symptomatic or cryptogenic localization-related epilepsy, and two had epilepsy with generalized and focal signs. Twenty-three of the patients were followed for more than 2 years. The patients were treated with arrest after focal seizure onset (2 cases), sensory protection against reflex seizures (3 cases), avoidance of non-specific seizure-precipitating factors ('life hygiene', 16 cases), and/or miscellaneous interventions (8 cases). The main outcome measures were complete seizure control (more than 2 years) or sufficient improvement to continue with NPC treatment alone. Eight of the 23 patients were completely seizure free for more than 4 years, and three were sufficiently improved to continue NPC treatment without drugs. Trends were observed for patients with idiopathic generalized epilepsies with less than seven convulsive seizures, and with only one seizure type to respond better to NPC treatment. The duration of epilepsy, and the finding of generalized epileptiform discharge in the EEG had no influence on the outcome. Rational NPC treatments which are aimed at specific factors in the precipitation and development of epileptic seizures can be useful therapeutic alternatives for patients with milder forms of epilepsy. Apart from photosensitive patients, those most likely to profit are patients with idiopathic generalized epilepsy, a maximum of six generalized tonic-clonic seizures which were precipitated by lack of sleep or excessive alcohol intake, and with no or rare concomitant absences. In such cases, NPC treatment may be as effective as pharmacotherapy and gives the patient a positive experience of regained self-control.- - - - - - - - - - ranking = 62.195178935195keywords = sleep (Clic here for more details about this article) |
4/140. Rectal diazepam: pitfalls of excessive use in refractory epilepsy.INTRODUCTION: The rectal administration of diazepam (DZP) has provided a safer existence to many epilepsy patients and their carers, when prolonged or serial seizures are present. However, in patients with frequent seizures, chronic, intermittent over-administration may occur, particularly in the presence of multihandicaps. methods: Six patients who experienced untoward effects from excessive rectal DZP are reported. In two patients, serial plasma levels of DZP and its active metabolites were monitored. RESULTS: Three patients exhibited a pattern of cyclic reappearance of seizures, interrupted by rectal DZP, followed by sedation and gradual awakening. The intervals were approximately 4 days. The three other patients had variable and complex symptoms with serial seizures and alternating states of tension, apathy, and sleepiness. The plasma levels of DZP and desmethyl-DZP showed rapid fluctuations. CONCLUSION: When rectal DZP is prescribed, chronic and excessive administration should be avoided. Fluctuating plasma-levels may probably support a cyclic reappearance of seizures in some patients. The combination of high bolus doses and a rapid drug clearance due to enzyme inducing co-medication may probably increase the risk for rebound reactions. Toxic, withdrawal, and epileptic symptoms may be intermingled and difficult to manage. A replacement strategy in the form of a prophylactic, oral, low dose benzodiaepine regimen may facilitate the discontinuation of this prescription pattern. Adequate counselling and medically appropriate, written directions for the use of rectal DZP is mandatory.- - - - - - - - - - ranking = 62.195178935195keywords = sleep (Clic here for more details about this article) |
5/140. The implementation and maintenance of the ketogenic diet in children.The ketogenic diet is an effective treatment for epilepsy in children. At Johns Hopkins Hospital more than 400 children have been placed on the ketogenic diet. The implementation and maintenance of this treatment require significant collaboration between the family and epilepsy Team. During initiation of the diet, in the hospital, parents attend classes on the history and mechanism of the diet, preparation of meals, psychological issues, complications and the management of childhood illnesses on the ketogenic diet. Many factors are considered in calculating a ketogenic formula. Age, weight, height and activity level are the obvious factors. However, secondary medical diagnoses, medications, neurological deficits, feeding issues and psychological issues are additional factors that affect the formulation of an optimal ketogenic prescription. Once this prescription has been formulated and implemented, many patients require fine-tuning of their ketogenic diets to get the best antiepileptic results while promoting growth. We believe that our success in sustaining this treatment is related to our fine-tuning and management practices.- - - - - - - - - - ranking = 2.9887232182549keywords = initiation, maintenance (Clic here for more details about this article) |
6/140. Potential hepatotoxicity of lamotrigine.Lamotrigine is a new antiepileptic drug that is effective for a broad range of seizures in adults and children. Three children with seizures of different causes who were treated with lamotrigine and developed reversible hepatotoxicity are reported. In one child, this therapy led to relatively severe hepatic failure that required and responded to aggressive therapy. Unlike most of the previously reported six patients with similar severe hepatic involvement, this patient's liver function and blood hepatic enzymes became normal. All three patients were on multiple drugs, and two were in epilepsia partialis continua secondary to encephalitis. Two of the patients had relatively rapid medication titration schedules. The close time relationship between the initiation of the lamotrigine therapy and the reversal of the liver abnormalities with lamotrigine discontinuation argues against a cause other than the lamotrigine; however, because of the complexity of the reported cases, the causality remains an assumption. review of the literature revealed six other previously reported patients (five adults and one child) who had hepatotoxicity during lamotrigine therapy, with or without associated multisystem failure, and similar patient profiles. Lamotrigine is generally a safe and effective medication; however, it should be used with caution in patients on polytherapy and in those with complicated acute systemic and central nervous system conditions, such as fever, status epilepticus, epilepsia partialis, and encephalitis.- - - - - - - - - - ranking = 1keywords = initiation (Clic here for more details about this article) |
7/140. Comparison of auras and triggering factors in epilepsy.case reports of five patients are presented, each with a specific aura at the onset of the seizures. All of these patients' had seizures during the waking state. Their auras were carefully replicated and presented to the patients under various conditions. The presentation of the auras evoked neither clinical nor EEG evidence of seizures. A sixth patient had seizures only when asleep which were preceded by vivid nightmares. Since the seizures occurred only when the patient was asleep, we considered that the seizures could be reflex in nature and evoked by a dream. Replication of the dream, however, did not evoke clinical or EEG evidence of epilepsy. The dreams, therefore, were auras or a part of the seizure complex.- - - - - - - - - - ranking = 124.39035787039keywords = sleep (Clic here for more details about this article) |
8/140. Valproate, hyperandrogenism, and polycystic ovaries: a report of 3 cases.BACKGROUND: Reproductive endocrine disorders characterized by menstrual disorders, polycystic ovaries, and hyperandrogenism seem to be common among women treated with sodium valproate for epilepsy. OBJECTIVE: To describe the development of valproate-related reproductive endocrine disorders in women with epilepsy. DESIGN: Case report. patients: Three patients developed a reproductive endocrine disorder during treatment with valproate. It was characterized by hyperandrogenism and polycystic ovaries in all cases, and it was associated with weight gain and menstrual disorders in 2 of the 3 women. RESULTS: Replacing valproate with lamotrigine resulted in a decrease in serum testosterone concentrations in all 3 women. The polycystic changes disappeared from the ovaries in 2 of the women after valproate therapy was discontinued, and the 2 women who had gained weight and developed amenorrhea while being treated with valproate lost weight and resumed menstruating after the change in medication. CONCLUSIONS: The 3 cases presented here illustrate the development of reproductive endocrine disorders after the initiation of valproate therapy in women with epilepsy. The disorders were characterized by hyperandrogenism and polycystic ovaries in all cases, and were associated with weight gain and menstrual disorders in 2 of the 3 women. An evaluation of ovarian structure and function should be considered in women of reproductive age being treated with valproate for epilepsy, especially if they develop menstrual cycle disturbances during treatment.- - - - - - - - - - ranking = 1keywords = initiation (Clic here for more details about this article) |
9/140. Lamotrigine-induced tic disorder: report of five pediatric cases.PURPOSE: To describe the clinical spectrum of lamotrigine (LTG)-induced tics (an uncommon side effect) in children. methods: Retrospective analysis of patients from our hospital-based practice who developed tics while on LTG. Data obtained from medical records, interviews with parents, video-EEGs, and homemade videotapes. RESULTS: Three males and two females (range, 2.5-12 years; mean, 6.9 years) developed a movement disorder within the first 10 months of therapy (maintenance doses, 4-17 mg/kg/day). Four patients exhibited simple motor tics; one patient experienced mostly vocal (i.e., gasping sounds) tics. Laryngoscopic evaluation of one 2.5-year-old with repetitive gasping sounds was normal. In three cases, tics resolved completely within 1 month of drug cessation; tics recurred in two of these patients after reintroduction of LTG. A fourth patient experienced gradual improvement after stopping LTG over 4 months; the fifth patient's simple motor tics improved spontaneously with a reduction in medication. None of the patients had clinical features of a neurodegenerative disorder, and none met diagnostic criteria for tourette syndrome. Two patients, however, had a diagnosis of acquired epileptic aphasia syndrome, and one patient had nonprogressive expressive and receptive language dysfunction. A fourth patient had global static encephalopathy, and the fifth patient had only attentional problems. In all patients, tics were not associated with ictal EEG changes. CONCLUSIONS: LTG may infrequently induce simple motor tics, vocal tics, or both. patients with severe language dysfunction may be particularly susceptible to this uncommon side effect. Further studies are necessary to clarify the population at risk.- - - - - - - - - - ranking = 0.39774464365098keywords = maintenance (Clic here for more details about this article) |
10/140. Tonsillar pain mimicking glossopharyngeal neuralgia as a complication of vagus nerve stimulation: case report.An adolescent girl presented with severe, lancinating tonsillar pain exacerbated by swallowing 6 weeks after initiation of left vagus nerve stimulation for intractable epilepsy. Her symptoms mimicked those seen in glossopharyngeal neuralgia and were relieved by temporary cessation of stimulation. Gradual reinstitution of therapy with alteration in stimulus parameters resulted in improved seizure control as well as cessation of pain symptoms. Direct stimulation of the vagus nerve may result in vagoglossopharyngeal neuralgia, which, in this case, was amenable to stimulus modification.- - - - - - - - - - ranking = 1keywords = initiation (Clic here for more details about this article) |
