Epilepsy may be the earliest and the sole clinical manifestation of a brain tumor. The existence and the character of the brain tumor cannot be predicted based solely on the severity and pattern of seizure. Epilepsy is common in patients with brain tumors, however, it is less common to find brain tumors in patients with epilepsy. Due to the slow progression of brain tumors and limitations in the use of brain computed tomography (CT), it often takes a long time to diagnose brain tumors in an epileptic child. Relief of epilepsy by surgical removal of the etiologic brain tumor appears to be promising. We report two cases of brain tumors presenting as intractable epilepsy with a discordant neuroimage. Therefore for those children taking long-term anticonvulsants with frequent recurrence, it appears reasonable to perform magnetic resonance imaging (MRI) to enable discovering of any organic lesions.

The risk of neurodevelopmental disability from birth asphyxia secondary to intrapartum complications and obstetric mismanagement is generally overestimated. Between 8-17% of all cerebral palsy is associated with adverse perinatal events suggestive of asphyxia. Less than 10% is probably due directly to birth asphyxia itself. Studies have shown that different methods of intrapartum assessment of fetal well-being (fetal heart rate monitoring, fetal scalp pH, presence of meconium) do not correlate well with each other or with neonatal parameters (acid-base status at birth, Apgar scores, seizures, neurological behaviour) and outcome measures (death, cerebral palsy, mental retardation). The prevalence rate of cerebral palsy in most communities of 2.0-2.5 per 1000 children is not falling in spite of increasing use of obstetric and neonatal interventions aimed at preventing or treating birth asphyxia. Prediction of neurodevelopmental outcome of birth asphyxia is difficult because of a limited ability to measure birth asphyxia quantitatively in the antenatal and neonatal period. The terminology used to describe the condition is often confusing. It has been recommended that substantial cerebral hypoxia can only be presumed when four criteria are met: the infant has an Apgar score < or = 3 at 10 minutes, metabolic acidosis at birth, hypotonia for several hours and seizures. For the paediatrician, a number of clinical observations and laboratory investigations have been suggested as helpful in the prediction of death or disability among term infants with birth asphyxia.

Classification and electroencephalographic studies were based on 215 children with chronic headache ranged in age from 3 to 16 years (9.53 +/- 2.86 years old) who were referred to the Pediatric Neurology Clinics of National Taiwan University Hospital due to chronic or severe headache from December 1989 to December 1992. The most common type of headache was seizure headache which constituted 27.0% of all these cases. Migraine headache accounted for 22.3%. The abnormal and borderline electroencephalogram (EEG) rate in seizure headache patients were 75.9% and 24.1% respectively. Comparing the results of migraine patients were 8.3% and 8.3% respectively. Seven cases have been diagnosed as orthostatic dysregulation clinically. All of them presented normal EEG. The response of seizure headache to anticonvulsants was good in the patients with abnormal (87.9%) and borderline EEG (55.6%). We conclude that seizure headache is not uncommon in children and it responses good to anticonvulsants.

From 1982 to 1991, there were 57 patients diagnosed with various intracranial disorders manifested initially with acute hemiplegia at the Department of Pediatrics, National Taiwan University Hospital. There were 33 boys and 24 girls, aged 12 days to 18 years old. In etiological consideration, cerebrovascular disease (66.7%), intracranial tumors (12.3%) and head trauma (10.5%) accounted for most of the cases. Besides acute hemiplegia, cranial nerve palsy (47.4%), disturbed consciousness (42.1%), headache (42.1%), vomiting (31.6%), focal seizure (21.1%) and fever (21.1%) were also common manifestations. Neuroimage studies of CT/MRI scan and angiography were the most useful diagnostic tools. Treatment modalities included medical treatment in 25 patients and surgical intervention in 16 patients and supportive treatment in the others. There were 12 fatal cases, half of whom died directly of intracranial pathology. The survivors exhibited various neurological deficits, in which motor deficits, mental retardation, and subsequent seizures were the three most common sequelae.

From October 1982 to June 1992, 94 neurologically normal Chinese Children (50 males & 44 females) with benign partial epilepsy of childhood with centrotemporal spikes were studied among 1847 epileptic infants and children. Their ages at onset were between 3.6 and 12 years (a mean of 7.3 years). All of them had normal birth and developmental histories. Seven patients (7.5%) had past history of febrile convulsion and 12 cases (12.8%) had family history of epilepsy. The depicted seizure patterns were protean, but most attacks (83%) occurred during sleep (nocturnal & diurnal). The duration of active period and seizure frequency had no significant difference in terms of sex and treatment, but early-onset patients (< 7.3 years) had statistically significant longer duration of active period than that of late-onset group (p < 0.01). We recommend that antiepileptic drug treatment is not essential for this disease. Even if antiepileptic drug is used, the low-dosed carbamazepine is suggested.

Tuberous sclerosis (TS) is a multiple-system disease involving the brain, skin, kidneys, heart and other visceral organs. There were 18 children with TS at our clinic, and complete studies of these patients and their families were performed. Male to female ratio was 11:7. Age at diagnosis was from 1 month to 18 years. Seizures (infantile spasm, generalized and partial epilepsy), skin lesions and intracranial calcifications were the most common clinical manifestations. Mental retardation was closely correlated with seizure attacks. Neoplasms of the brain, retina, heart, lung and kidneys were all encountered. Hypopigmented macules, intracardiac tumors and infantile spasms were usually the first signs in younger ages and can give hints of early diagnosis of TS. In total, six patients had positive family histories and one of them had non-penetrating parents. Detailed family studies are mandatory prior to genetic counseling.

Fourteen patients (10 boys, 4 girls) aged from 4 months to 14 years old were diagnosed with mitochondrial disease based on the clinical manifestations together with abnormal muscle mitochondrial morphologies. Their clinical diagnoses included Leigh syndrome, three; Menkes' syndrome, three; Kearns-Sayre syndrome, two; myoclonic epilepsy with ragged fibres, one; and infant-onset progressive myoclonic epilepsy, one; fatal infantile mitochondrial myopathy, one; fatty acid oxidation defect, two; and myopathy with cardiopathy, one. Organs involved other than muscles included central nervous system, ten; heart, six; eye, two; liver, two; and kidney, two. Clinical manifestations varied to include hypotonia, seizures, myoclonus, mental retardation, nystagmus, ataxia, ptosis, ophthalmoplegia, retinal degeneration, muscle atrophy, spasticity etc. Nine had an abnormal rise in lactate after glucose loading. Ragged-red fibres were found in four patients. Abnormal mitochondrial morphology included abnormal accumulation, abnormal cristae pattern of tubular, concentric, or parallel form, some contained osmiophilic inclusion bodies. One patient of Leigh syndrome had had brain necropsy which showed intramyelin splitting of myelinated axons.

A 5-month-old male infant, diagnosed as Leigh syndrome, presented with developmental delay, episodic apnea, metabolic acidosis, and myoclonic seizures. The magnetic resonance image of brain showed multiple symmetric low signals over the putamen in the T1-weighted axial view and linear high signal over the brainstem in the T2-weighted sagittal view. On electron microscopy, subsarcolemmal aggregation of abnormal mitochondria in muscle cells were found via biopsy. Small samples of myocardium, liver and brainstem, obtained via necropsy, were subjected to pathological examinations. On light microscopy, vacuoles were found in the myocardium and hepatocytes, while spongiform lesions in the neuropils, round cell infiltration, and vascular proliferation were observed in the brainstem. On electron microscopy, intramyelin splittings were observed in the spongiform lesions. We believe that intramyelin splitting must play an important role in the pathogenesis of spongiform lesions in Leigh syndrome.

Even without electrolyte imbalance, dehydration and fever, seizures are found occasionally in the cases of mild diarrhea. Such patients have shown favorable outcome during long-term follow-up. Twenty cases (10 boys and 10 girls) of benign seizure with mild diarrhea have been diagnosed at the Pediatric Department of Cathay General Hospital from January 1987 to March 1991. Ages-of-onset ranged from 3 months to 43 months (mean 19 months). Most cases were found between December and March (16 cases, 80%). Most seizure episodes were from 2 to 5 times (10 cases, 50%); the durations of seizures were mostly within a 5-minute period (16 cases, 80%). All seizures were generalized and symmetric, including tonic-clonic (13 cases, 65%), tonic (5 cases, 25%), and clonic (2 cases, 10%). Six out of 11 cases (54.5%) showed Rotazyme (Latex agglutination) positive. After six month to four year follow up, no patient had suffered any type of epilepsy, and psychomotor development was normal in all. Further discussion of clinical features is provided.

Three cases with distinct clinical manifestations associated with rhabdomyolysis syndrome were encountered in this hospital's pediatric intensive care unit. Elevation of serum creatine phosphokinase, uric acid, potassium, inorganic phosphate and hypocalcemia with seizure were noted. The three patients all had signs of acute renal failure. One died of respiratory failure, and autopsy revealed multiple intrathoracic anomalies. The remaining two recovered completely from rhabdomyolysis. It is of importance to early recognize any acutely ill patient as having rhabdomyolysis syndrome when there is elevation of muscle enzymes, hypocalcemic seizure, positive orthotolidine reaction of urine strip while negative finding of red blood cell. The syndrome may damage the kidneys. Appropriate management to induce diuresis usually can salvage this potentially life-threatening condition.
