EKG abnormalities in children and adolescents with symptomatic temporal lobe epilepsy.

BACKGROUND: Changes in cardiac rate and rhythm are often found in adult patients with temporal lobe epilepsy (TLE) and could be involved in the pathogenesis of sudden unexplained death (SUDEP). However, little is known about heart rate (HR) variability in pediatric patients with TLE. OBJECTIVES: To investigate ictal and peri-ictal HR abnormalities in children and adolescents with medically refractory symptomatic TLE and to determine the influence of focus localization and laterality. METHODS: Patients younger than 18 years, with drug-resistant unilateral symptomatic TLE and presenting with at least one habitual complex partial seizure (CPS) during presurgical noninvasive video-EEG monitoring, were enrolled. Synchronous single-channel EKG recordings were analyzed during the preictal, ictal, and postictal stages. RESULTS: Twenty patients fulfilled the inclusion criteria. Seventy-two temporal lobe seizures (TLSs) were analyzed. Ictal tachycardia was found in 71 TLSs (98%), whereas ictal bradycardia was not observed. During preictal stages, tachycardia occurred in 20 seizures and mild bradycardia in 3. In 44 seizures (62%), tachycardia was still present >60 seconds after EEG seizure termination. Cluster analysis revealed significant differences in HR evolution depending on location and side of seizure onset: Early and high HR increase was primarily associated with right mesial TLSs. CONCLUSIONS: Cardiovascular dysregulation is common during temporal lobe CPSs in children. These results confirm a right hemispheric lateralization of sympathetic cardiac control.

Glatiramer acetate treatment in patients with childhood and juvenile onset multiple sclerosis.

BACKGROUND: Recent data indicate that in multiple sclerosis disease onset before the age of 16 is more common than previously assumed. However, current therapeutic options are limited to the treatment of acute attacks in these patients. Glatiramer acetate has been successfully applied in adults with relapsing-remitting multiple sclerosis, but there are no data available about the use of glatiramer acetate in childhood and juvenile onset multiple sclerosis. METHODS: Seven patients with relapsing-remitting multiple sclerosis and disease onset between 9 and 16 years of age were treated with daily subcutaneous injection of 20 mg glatiramer acetate (Copaxone). Patients were followed for 24 months. Treatment was initiated in all patients before the age of 18. RESULTS: The use of glatiramer acetate in our cohort of early onset multiple sclerosis patients was safe and well tolerated. Two out of seven patients remained relapse-free during the two year period. Clinical disability as measured by the EDSS remained stable in three out of seven patients. CONCLUSION: Due to the small number of patients the efficacy of the treatment has to be interpreted with caution. However, there might be a more pronounced treatment benefit in patients with low disability at treatment initiation and early treatment onset.

IHS criteria and gender: a study on migraine and tension-type headache in children and adolescents.

The aim of this study was to investigate whether the IHS criteria for migraine and tension-type headache depend on gender. Among 409 children and adolescents with recurrent idiopathic headache seen at a university outpatient clinic, girls had significantly more often migraine with aura. Also, there was a trend towards a higher frequency of tension-type headache in girls. In migraine, aggravation of headache by physical activity and occurrence of aura symptoms were more common in females, whereas vomiting and phonophobia occurred more often in males. In tension-type headache, females more often reported mild intensity of headache. All other criteria were similar in both sexes. Age influenced the expression of some of the accompanying symptoms in the various types of migraine, but had only minimal influence on other diagnostic criteria of migraine and tension-type headache in females as well as in males. Our study suggests that the frequency of migraine (except that of migraine with aura) is similar among girls and boys, that tension-type headache may occur more often in girls, and that gender has some influence on the IHS criteria for migraine, but almost no influence on those of tension-type headache.

IHS criteria for migraine and tension-type headache in children and adolescents.

We investigated the influence of age on the IHS criteria for migraine and tension-type headache in 437 consecutive children and adolescents and found the following age-associated statistically significant differences: migraine duration, occurrence of migraine aura, and bilateral location of tension-type headache were more often fulfilled by adolescents, whereas aggravation of headache by physical activity (in migrainous disorder) and photophobia (in migraine with aura) were more often fulfilled by children. Accordingly, there are only a few differences concerning the fulfillment of the IHS criteria for migraine and tension-type headache in children and adolescents. Independent of age, the intensity of headache and the presence or absence of nausea are most important for differentiating the two major types of idiopathic headache. The sensitivity of the IHS criteria for migraine could be increased by reducing the minimum duration of migraine and by allowing the diagnosis of migraine when severe headache is associated with nausea, even though the criteria of location, quality, and aggravation by physical activity are not fulfilled.

Diagnosis of headache in childhood and adolescence: a study in 437 patients.

We investigated whether the criteria for idiopathic headache published by the International Headache Society (IHS) are useful in childhood and adolescence and compared the diagnoses according to this classification with those of Vahlquist. We used a semi-structured questionnaire to examine a total of 437 children and adolescents referred consecutively to a headache outpatient clinic. Twenty-eight of 437 patients were excluded because of symptomatic or unclassifiable headache. Of 409 patients with idiopathic headache, 70.4% had definite migraine or tension-type headache (IHS 1.1, 1.2, 2.1, 2.2), 20.5% had a migrainous disorder (IHS 1.7) and 9.1% had headache of the tension-type not fulfilling the criteria (IHS 2.3). In the differential diagnosis of migraine and tension-type headache the intensity of pain, aggravation of headache by physical activity, nausea and vomiting were the most important features. The quality of pain, photo- and phonophobia were less helpful and location least important. The duration of migraine attacks was less than 2 h in 19.0% of the migraine patients. In general, the diagnostic criteria of migraine were highly specific but less sensitive, and those of tension-type headache highly sensitive but less specific. The agreement between IHS criteria and those of Vahlquist was marked (kappa = 0.57). We conclude that the IHS criteria are useful for classifying headache in children and adolescents referred to a headache outpatient clinic. A forthcoming modification of the IHS criteria should consider a reduction of the minimum duration of migraine attacks from 2 h to 1 h and should try to increase the sensitivity of the criteria for migraine and the specificity of the criteria for tension-type headache.
