Status epilepticus after the initial diagnosis of epilepsy in children.

OBJECTIVES: To determine the risk and predictors of status epilepticus in children after they have been diagnosed with epilepsy. METHODS: In a prospective community-based cohort study of 613 children, the occurrence of status epilepticus after the initial diagnosis of epilepsy was ascertained. Parents were called every 3 months, and interval medical records were reviewed every 6 months. Predictors of primary interest included a history of status before the diagnosis of epilepsy, age at onset, underlying etiology, and epilepsy syndrome. Data were analyzed with chi2 tests, Kaplan-Meier analyses, and Cox proportional hazards models. RESULTS: Of 613 children followed a median of 8.0 years, 58 (9.5%) had > or =1 episode of status epilepticus during follow-up evaluation. The first episode occurred a median of 2.5 years after initial diagnosis (range, <1 month to 8.8 years). A history of previous status epilepticus was strongly associated with subsequent status epilepticus (18/56 [32.1%] vs 40/557 [7.2%]; p < 0.0001). Younger age at onset and symptomatic etiology contributed independently to the risk of status epilepticus. Mortality was higher in children with status epilepticus before diagnosis, largely secondary to underlying cause. CONCLUSIONS: Status epilepticus occurs in approximately 10% of children after initial diagnosis of epilepsy. Status epilepticus before initial diagnosis, young age at onset, and symptomatic etiology independently influence the risk of status epilepticus. In those without status epilepticus before diagnosis, the risk is modest and is realized over a prolonged period. For children at highest risk, maintaining abortive therapy in the home may be a reasonable precaution.

Early development of intractable epilepsy in children: a prospective study.

BACKGROUND: Little is known about early prediction of intractable epilepsy (IE) in children. Such information could help guide the early use of new therapies in selected patients. METHODS: Children with newly diagnosed epilepsy (n = 613) were prospectively identified from child neurology practices in Connecticut (1993--1997) and followed-up for the occurrence of IE (failure of > or = 2 drugs, > or = 1 seizure/month, over 18 months) [corrected]. Etiology and epilepsy syndromes were classified per International League Against Epilepsy guidelines. RESULTS: The median follow-up is 4.8 years, and 599 (97.7%) have been followed for more than 18 months. Sixty children (10.0%) have met the criteria for IE, including 34.6% with cryptogenic/symptomatic generalized, 2.7% with idiopathic, 10.7% with other localization-related, and 8.2% with unclassified epilepsy (p < 0.0001). After multivariable adjustment for epilepsy syndrome, initial seizure frequency (p < 0.0001), focal EEG slowing (p = 0.02), and acute symptomatic or neonatal status epilepticus (p = 0.001) were associated with an increased risk of IE, and age at onset between 5 and 9 years was associated with a lowered risk (p = 0.03). The absolute number of seizures and unprovoked or febrile status epilepticus were not associated substantially with IE. CONCLUSIONS: Approximately 10% of children meet criteria for IE early in the course of their epilepsy. Cryptogenic/symptomatic generalized syndromes carry the highest risk and idiopathic syndromes the lowest. Half of IE occurs in children with nonidiopathic localization-related syndromes. Initial seizure frequency is highly predictive of IE. By contrast, absolute number of seizures and unprovoked or febrile status epilepticus are not.

Defining early seizure outcomes in pediatric epilepsy: the good, the bad and the in-between.

PURPOSE: To examine different approaches to classifying seizure outcomes. METHODS: In a prospective cohort study of children (N=613) with newly diagnosed epilepsy, seizure outcomes at 2 years were classified as 'good' (> or =1 year remission), 'bad' or 'intractable' (> or = AED failures, > or =1 seizure/month over > or =18 months), and 'indeterminate' (neither 'good' nor 'bad'). Outcomes at 2 years were compared to outcomes in those followed 4 or more years. The associations of three commonly studied prognostic factors, etiology, age at onset, and syndromic grouping with the three-level outcome were assessed. RESULTS: 595 (97.1%) children were followed > or =2 years. A 'good', indeterminate, and 'bad' outcome was present in 314 (52.8%), 235 (38.3%), and 46 (7.7%) children. Problems with treatment were recorded in 64.7% of the indeterminate group. In 390 children followed > or =4 years, early 'good' and 'bad' outcomes persisted in approximately 80%. About half of those with indeterminate 2-year outcomes later achieved remission, 8% met criteria for intractability, and 37% remained indeterminate. Most of the associations with etiology, age, and syndrome were due to variation in the proportion that met criteria for intractability and not remission. CONCLUSIONS: Many children have indeterminate outcomes, often in association with treatment issues. Clearly 'good' and 'bad' early outcomes can be identified and persist > or =2 years later. In the absence of pharmaco-resistance, lack of early remission (indeterminate outcome) is usually not associated with a bad outcome, at least over the next few years.

Two-year remission and subsequent relapse in children with newly diagnosed epilepsy.

PURPOSE: Although remission is the ultimate measure of seizure control in epilepsy, and epilepsy syndrome should largely determine this outcome, little is known about the relative importance of syndrome versus other factors traditionally examined as predictors of remission or of relapse after remission. The purpose of this study was to examine remission and relapse with respect to the epilepsy syndrome and other factors traditionally considered with respect to seizure outcome. METHODS: A prospectively identified cohort of 613 children with newly diagnosed epilepsy was assembled and is actively being followed to determine seizure outcomes. Epilepsy syndrome and etiology were classified at diagnosis and again 2 years later. Remission was defined as 2 years completely seizure-free, and relapse as the recurrence of seizures after remission. Multivariable analysis was performed with the Cox proportional hazards model. RESULTS: Five hundred ninety-four of the original 613 children were followed > or = 2 years (median follow-up, 5 years). Remission occurred in 442 (74%), of whom 107 (24%) relapsed. On multivariable analysis, idiopathic generalized syndromes and age at onset between 5 and 9 years were associated with a substantially increased remission rate, whereas remote symptomatic etiology, family history of epilepsy, seizure frequency, and slowing on the initial EEG were associated with a decreased likelihood of attaining remission. Young onset age (<1 year) and seizure type were not important after adjustment for these predictors. Relapses occurred more often in association with focal slowing on the initial EEG and with juvenile myoclonic epilepsy. Benign rolandic epilepsy and age at onset <1 year were associated with markedly lower risks of relapse. About one fourth of relapses were apparently spontaneous while the child was taking medication with good compliance, and more than half occurred in children who were tapering or had fully stopped medication. CONCLUSIONS: A large proportion of children with epilepsy remit. Symptomatic etiology, family history, EEG slowing, and initial seizure frequency negatively influence, and age 5-9 years and idiopathic generalized epilepsy positively influence the probability of entering remission. Factors that most influence relapse tend to be different from those that influence remission.

How well can epilepsy syndromes be identified at diagnosis? A reassessment 2 years after initial diagnosis.

PURPOSE: Epilepsy syndromes can be identified very early in the course of a seizure disorder. It is unclear how accurate and resilient such early classifications are. We compared the classification of epilepsy syndromes made previously on the basis of information available at diagnosis with those made 2 years later in a cohort of children with newly diagnosed epilepsy. METHODS: Children (n = 613) were prospectively identified at the time of initial diagnosis by participating physicians in Connecticut between 1993 and 1997. Classification of epilepsy syndrome according to International League Against Epilepsy guidelines was made previously based on all relevant information available at diagnosis. All cases were reclassified again after 2 years of additional evidence had accumulated. The distributions of syndromes at diagnosis and at 2 years are compared and reasons for changes examined. RESULTS: After 2 years, syndromes remained the same in 86.3% of the cohort and changes occurred in 13.7% (n = 84). Evolution of the syndrome occurred in 24 children (3.9%), and rectification to the initial diagnosis occurred in 60 children (9.8%). The most common scenario for evolution of a syndrome was from West syndrome (n = 5), undetermined (n = 4), or symptomatic localization-related epilepsy (n = 3) to the Lennox-Gastaut syndrome. The most common rectification of initial classifications involved incompletely classified syndromes (cryptogenic localization-related and undetermined syndromes; n = 36). In a few instances, a fully specified syndrome was reclassified to another apparently unrelated syndrome. In these cases, initial information at diagnosis had been difficult to interpret. CONCLUSIONS: Epilepsy syndromes can, for the most part, be identified at the time of initial diagnosis. Two years later, rectifications were made in only 9.8% of cases, and most of these involved syndromes that represented incomplete classifications in the first place. Significant changes were rare. The International League Against Epilepsy classification of the epilepsies can be meaningfully applied in epidemiological studies of newly diagnosed pediatric epilepsy.

An open multicenter efficacy and safety evaluation of amlodipine in the treatment of symptomatic myocardial ischemia.

The efficacy and safety of amlodipine (5-10 mg) once daily were studied in an open study in patients with symptomatic myocardial ischemia. The study is ongoing and this report is based on an interim analysis of data from 78 patients. A 2-week baseline period in which patients maintained their current antianginal therapy was followed by a 10-week treatment period with 5-10 mg of amlodipine/day. Both the median number of angina attacks per week and the median number of nitroglycerin (NTG) tablets consumed/week were significantly reduced after amlodipine (mean daily dose of 8.6 mg) when compared with baseline (p < 0.05). A total of 98.4% of patients (63/64) experienced a reduction in the frequency of angina attacks/week and 91% of patients (58/64) had angina attacks reduced to < or = 2/week. In self-assessments, 95% of patients (55/58) reported improved angina control and 91% (53/58) felt their ability to perform usual activities had improved. Twenty-seven patients experienced adverse events reported as drug related. The most common adverse event noted was edema. Amlodipine once daily significantly reduced the incidence of angina attacks and the concomitant need of nitroglycerin for relief of symptoms and thus improved the patients' ability to perform daily activities. Most adverse events reported were mild or moderate and the incidence is as would be expected in this patient population.

Drusen of the optic disc.

Although optic disc drusen have been of interest to ophthalmologists for more than 100 years, their etiology and many aspects of their relationship to other clinical conditions remain obscure. They have been clinically observed in 0.3% of the population, although autopsy studies suggest an incidence of 2%. Drusen are seldom accompanied by visual symptoms; however, decreased vision and visual field changes may occur. The historical and epidemiological aspects of drusen are reviewed; clinical and histological features, as well as special diagnostic techniques (ultrasonography and fluorescein angiography) are discussed in detail.

Lyme carditis: complete AV dissociation with episodic asystole presenting as syncope in the emergency department.

We report a case of Lyme carditis in an otherwise-healthy young male who presented to the Emergency Department (ED) with syncope and a possible seizure. This patient, without documented history of Lyme disease, acutely developed third-degree atrioventricular (AV) block with episodic asystole, which required placement of a transvenous pacemaker in the ED and resolved only after the patient had been placed on ceftriaxone. We discuss the significance of Lyme carditis and its increasing prevalence, and review the current literature. We also recommend appropriate screening modalities for patients with known Lyme disease, or an atypical profile for cardiac abnormalities.
