Clinical categorization of 312 children with chronic headache.

Three hundred and twelve children referred to an outpatient pediatric neurology clinic, with headache that lasted more than 3 months, were retrospectively reviewed. On average, the age of pain onset was 8.4 years. Migraine was diagnosed in 54% of these children and tension-type headache was found in 22% of those with chronic headache. Most children (85%) had common migraine, while classic and complicated migraine was found in only 8.8% and 5.3%, respectively. Brief headaches, lasting from seconds to a few minutes, were found in 5.1% of the children evaluated. In this subgroup, a high rate of epileptic EEG activity was found. Out of 110 children who had undergone computerized tomography, only one was pathological (posterior arachnoid cyst). Our results indicate that chronic and recurrent headache without accompanying neurological symptoms are usually benign and therefore in most cases neuroimaging is not indicated.

The value of EEG in children with chronic headaches.

To establish the usefulness of electroencephalography (EEG) as a diagnostic tool in the evaluation of headaches in children, we retrospectively reviewed the records of all children referred to our outpatient neuropediatric clinic because of recurrent headaches. Of 312 children, 257 (82%) underwent EEG tracings: 143 of the children who had had EEG recordings were diagnosed as migraineurs. In 31 (12%) of the children, the EEG revealed epileptic activity. The highest incidence of epileptic EEG activity was found amongst the children with very brief headaches. In 22 (8.6%) of the children, diffuse or focal slowing was detected. The group with migraine headache had a significantly higher incidence of slowing than the group with other types of headaches. There was no correlation between focal EEG abnormalities and brain radioimaging studies or clinical course. We conclude that despite the high incidence of epileptic abnormalities, the contribution of EEG to diagnosis and treatment in children with chronic headache is minimal, and should not be routinely prescribed in these children.

Jittery babies: a short-term follow-up.

Thirty-nine full-term babies, appropriate for gestational age, and otherwise healthy, were followed-up in our neurology clinic because of jitteriness, until complete resolution of symptoms and neurological findings. The babies were examined at 3 month intervals, and were classified according to the severity of their associated neurological findings, hypertonicity and increased tendon reflexes, into two groups: 'mild' (n = 24), and 'moderate-to-severe' (n = 15). The mean follow-up period was 13.5 months. In 81% of the study population, jitteriness and neurological findings disappeared before the age of 9 months. In only 11% did they persist beyond the age of 1 year. The mean time until disappearance of associated neurological findings was significantly shorter (5.5 months) in the mild group, compared to the moderate-to-severe group (9.5 months). Only one infant displayed motor delay and required physiotherapy.

Clinical significance of markedly elevated serum creatine kinase levels in patients with acne on isotretinoin.

Muscle-related complaints and high creatine kinase (CK) blood levels have been reported in 16-51% of patients with acne treated with isotretinoin. It has been suggested that this retinoid and exercise have a synergistic effect on muscle. The presence of marked hyperCKemia during the treatment raises concern about rhabdomyolysis. The objective of this report was to evaluate the incidence, course and clinical significance of severe hyperCKemia in isotretinoin therapy for acne. Out of 442 patients on isotretinoin, we reviewed 7 patients (1.58%) with CK values above 5,000 IU/l. Only two of them had myalgia. Physical activity or intramuscular injection prior to blood testing was reported in 6 patients. CK values returned to normal within 2 weeks and all subjects except 2, completed treatment. In conclusion, marked hyperCKemia with or without muscle-related complaints in isotretinoin-treated patients with acne is a benign phenomenon.
