A qualitative study was performed to investigate the individual experience of seizures and epilepsy in children and adolescents. Forty-one patients aged between 6 and 18 years old and affected with idiopathic epilepsy underwent one or more semi-structured interviews in a hospital day unit. Children aged 7 years or older could describe the experience of partial fits (in one case also of a presumably generalized fit). Seizures which occurred 6-12 months before had often been forgotten. Psychic involvement was reported in 90.3% cases, even when seizures had been classified as partial motor according to the parents' description. Social status and school achievement had no significant influence on the patient's ability to express his or her feelings, but some children had serious difficulty finding appropriate words to describe unfamiliar experiences; other patients used a simile, uncommon expressions or odd names to describe the fit. A poor relationship was found between seizure severity and patient's discomfort, and the image of the disease appeared independent of the experience of the seizures. As regards the epilepsy itself, patients seemed to suffer from generic problems rather than from specific concern about it, but some adolescents inserted their thoughts about the disease into reflections on their existential condition.

Childhood seizures are encountered frequently in the primary care setting. Seizures can cause considerable embarrassment and discomfort--as well as dangerous consequences--if not properly treated. Accurate diagnosis often depends on history and a parent's or teacher's clear and reliable description of the seizure. About two-thirds of properly treated patients achieve seizure remission within 10 years of diagnosis. In this article, the authors review standards of treatment and present the latest findings on the treatment of epilepsy. The goal of pharmacologic treatment is to reduce the frequency of seizures with few adverse effects. Because all antiepileptic drugs affect cognition to same degree, diminishing the potential cognitive and psychosocial effects of epilepsy is also a treatment goal. Commonly used and new antiepileptic drugs are discussed. Patient education is an important part of care and requires discussion of beliefs about epilepsy, lifestyle, self-esteem, and resources.

In the last 30 years there has been great interest in the use of saliva in therapeutic drug monitoring. Numerous investigators have suggested that saliva be used as an alternative body fluid for the therapeutic drug monitoring of anticonvulsant drugs. Not only can saliva be obtained easily on multiple occasions with minimal discomfort to the patient but, more importantly, useful relationships exist between the saliva and blood concentrations of the most commonly used anticonvulsant drugs. The measurement of anticonvulsant drug concentrations in saliva has been applied to pharmacokinetic and pharmacodynamic studies, and for therapeutic drug monitoring in a variety of seizure disorders. However, this simple and non-invasive method is not widely accepted in clinical practice. Several recent developments in sample collection and analytical methods, and the growing interest in free drug concentrations, provide a renewed impetus for saliva sampling for therapeutic drug monitoring of anticonvulsant drugs. Salivary flow rates vary significantly both between individuals and under different conditions. The use of stimulated saliva has several advantages over resting saliva. The salivary flow rate and pH, sampling conditions, contamination and many other pathophysiological factors may influence the concentrations of the medication in saliva. However, under standardised and well-controlled sampling condition, therapeutic drug monitoring of anticonvulsant drugs in saliva can be useful for determining compliance with medication in paediatric patients, for analysing the concentration of free drug and in situations where repeated sampling is necessary. Saliva is an alternative matrix for the therapeutic drug monitoring of carbamazepine, phenytoin, primidone and ethosuximide because the concentrations of these medications in saliva reflect the concentrations of the drug in serum. This is not the case for valproic acid (valproate sodium) and some controversy exists for phenobarbital. Further studies are required to assess the clinical value of monitoring anticonvulsant drugs and their metabolites in saliva, to examine the influence of pathophysiological factors on salivary drug concentrations, to improve the design of special devices to reproducibly and conveniently collect saliva samples, and to develop and use new analytical methods to achieve more sensitive and accurate results.

Vagus nerve stimulation is an empirically based method for treatment of epilepsy by repeated stimulation of the left vagus nerve through implanted electrodes. Despite studies in animals and man, which show changes in brain electrophysiology, metabolism and neurochemistry, the mode of action remains unknown. Clinical testing has presented methodological challenges, as it is difficult to assess under double blind conditions a treatment which requires surgery and produces a sensation every time the stimulator comes on. This has nevertheless been successfully addressed in parallel design, controlled trials comparing high and low stimulation schedules. These have been performed in adults with medically intractable partial seizures, and demonstrated efficacy, safety and good tolerability. Efficacy, both in the controlled trials and in numerous reports arising from the considerable post-marketing experience is modest. Some 30% of patients achieve a 50% seizure reduction after 3 months of treatment, but this proportion progressively increases to about 50% after 18 months. Side-effects comprise: discomfort in the face or neck when the stimulator is activated, coughing, breathlessness on exertion and hoarseness of voice. All are related to intensity of stimulation and rapidly habituate in most subjects. In those patients who respond, a stimulus level can therefore generally be found which is acceptable to the subject. No indication other than refractory partial seizures in adults has been the subject of controlled trials, but post-marketing experience and uncontrolled reports indicate comparable efficacy and safety in a wide range of epilepsies, partial and generalized, idiopathic, cryptogenic, or symptomatic, in patients of all ages.

Sedation is being used increasingly in children to allay anxiety and discomfort. Sedation can also increase the efficiency of performing both diagnostic and therapeutic procedures in children. There are a wide array of available sedation methods that are used by radiologists, gastroenterologists, hematologists/oncologists and emergency room physicians everyday. Indiscriminate use of sedatives has led to seizures, respiratory arrests and death in a variety of practice settings. With improved monitoring capability, more potent drugs and better understanding of the pharmacokinetics in children, it is possible to provide batter care.

Hereditary fructose intolerance (HFI) is an autosomal recessive disease caused by catalytic deficiency of aldolase B (fructose-1, 6-bisphosphate aldolase). Herein we report on a case of hereditary fructose intolerance with initial presentation of episodic unconsciousness, seizure, hypoglycemia, hepatomegaly, and abnormal liver function since the patient was 11 months old. She was diagnosed as Reye's-like syndrome according to a liver biopsy done at 20 months of age. As she grew up, cold sweating, abdominal pain or gastrointestinal discomfort shortly after the intake of fruits was noted and she developed an aversion to fruits, vegetables and sweet-tasting foods. At 9 years of age, a fructose tolerance test signified a positive result that induced hypoglycemia, transient hypophosphatemia, hyperuricaemia, elevation of serum magnesium, and accumulation of lactic acid. Appropriate dietary management and precautions were recommended. The patient has been symptom-free and exhibited normal growth and development when followed up to 12 years of age.

Vagus nerve stimulation (VNS) is a neurophysiological treatment for patients with medically or surgically refractory epilepsy. Since the first human implant in 1989, more than 10 000 patients have been treated with VNS. Two randomized controlled studies have shown a statistically significant decrease in seizure frequency during a 12-week treatment period versus a baseline period when 'high stimulation' mode was compared with 'low stimulation' mode. The efficacy appears to increase over time. In general, one third of the patients show a >50% reduction of seizure frequency; one third show a 30-50% seizure reduction, and one third of patients show no response. Few patients become seizure-free. Side effects during stimulation are mainly voice alteration, coughing, throat paraesthesia and discomfort. When studied on a long-term basis, VNS is an efficacious, safe and cost-effective treatment not only in adults but also in children and the elderly. The precise mechanism of action remains to be elucidated. In recent years much progress has been made through neurophysiological, neuroanatomical, neurochemical and cerebral blood flow studies in animals and patients treated with VNS. Further elucidation of the mechanism of action of VNS may increase its clinical efficacy and our general understanding of some physiopathological aspects of epilepsy. Finally, VNS may become an alternative treatment for other conditions such as depression and pain.

Metallic devices generally represent a contra-indication for MRI scanning. Based on laboratory testing, the neuro cybernetic prosthesis (NCP) is labelled MRI compatible when used with a send and receive head coil. However, there are no published clinical data to support the safety of brain MRI in patients with the NCP. Our objective was to report clinical experience with such a population. We questioned 40 centres that had implanted the NCP system as of 10/1/99. If MRI had been performed on any vagus nerve stimulator patients, we collected information on these patients, the MRI technique used, any events noted during the scan, including both subjective reports (by the patient ), and observable (objective) changes noted by the staff. Twelve centres (30%) responded. Over a time period of 3 years, there were a total of 27 MRI scans performed in 25 patients. All scanners were 1.5 T. A head coil was used in 26 scans, and a body coil in one. The indications for the scans were diverse. Seven were related to the epilepsy, including aetiology or pre-surgical evaluation. Others were unrelated, including brain tumours, cerebral haematoma, vasculitis, headaches, and head trauma. Three scans were performed with the stimulator on, while 24 were performed with the stimulator off. One patient had a mild objective voice change for several minutes. No other objective changes were noted in any of the patients. One 11-year old reported chest pain while experiencing severe claustrophobia. Twenty-five patients denied any discomfort around the lead or the generator. We conclude that this clinical series supports the safety of routine brain MRI using a send and receive head coil in patients implanted with the NCP System.

Drugs for pediatric emergencies are useful for respiratory (croup, asthma), cardiologic (hypertensive crisis, acute congestive heart failure, arrhythmias, hypoxic spells), neurologic (seizures), metabolic (dehydration, hypoglycaemia), infectious (meningococcemia) or allergic (anaphylaxis) distresses. Pain management is always important whether to relieve or to prevent the discomfort which would happen during diagnosis or therapeutic procedures.

Fever is an important symptom of underlying disease condition and in general is considered harmful in pediatric age group as it may lead to febrile seizures, stupor, dehydration increase work of breathing, discomfort and tachycardia. The increase metabolic demands stress the patient with marginal cardiac and cerebral vascular supply. The hypothalamus controls the body temperature. The fever results due to resetting of the hypothalamus that occur from the prostaglandins produced by the pyrogens. Fever is treated variedly by the pediatricians. The physical therapy offers a simple and cost effective way of lowering the body temperature. The drugs as paracetamol, nimesulide and ibuprofen lower the temperature by inhibiting the prostaglandin synthesis. Paracetamol is considered the safest of all the antipyretic drugs. It is recommended that a combination of physical therapy such as tepid sponging and paracetamol is best way of controlling temperature.
