The intraosseous infusion has numerous advantages over other techniques that provide vascular access during emergencies. It is a rapid and safe alternate route for fluid and certain drug administration in the infant or child. Few contra-indications or restrictions exist and the success rate for the technique is very high, even when performed by paramedical personnel, and the rate of complications is very low. At this time the technique should be reserved for children in crisis such as cardiac arrest, shock, trauma, life threatening status epilepticus, or any situation in which the potential benefit of rapid venous access outweighs the low incidence of complication. Intraosseous infusion is intended only for emergency resuscitation and stabilization, after which another route of vascular access should be sought. The technique may offer even more promise for those who rarely care for critically ill children, because this skill is easily mastered with even limited opportunity for practice.

In the critically ill child, administration of fluids and medications via the intraosseous route often proves life-saving. The authors describe the case of a child with status epilepticus in whom phenytoin was administered via the intraosseous route, and seizure resolution and therapeutic serum levels were achieved. Intraosseous drug administration should be reserved for the rare critically ill child in whom vascular access proves impossible.

Giving a definition of analgesia in ICU needs to answer several questions: Why sedation? Which drugs can we use? How can we deal with sedation? (monitoring, continuous administration, weaning...)? Two different types of sedation must be considered: treatment-sedation (status epilepticus, tetanus, intracranial hypertension...) and comfort-sedation in anxious and/or restless and/or painful patients and in those necessitating mechanical ventilation. Analgesic consumptions vary widely with diseases and their outcome, background diseases and ICU environment. Several studies have shown that pain and analgesia are frequently neglected in ICU. The authors review the different drugs in use, with their advantages and drawbacks. A particular place is reserved to regional techniques, often underused in ICU. Indications are then fully discussed, according to several specific pathological conditions. Monitoring and weaning of sedation are also discussed at the end of the review.

Although midazolam has been proposed for the treatment of a variety of conditions such as anxiety, dyspnoea, hiccups and status epilepticus, terminal agitation is the only condition where its use is based on a reasonably large number of published clinical studies. A causal approach is generally recommended. Whenever possible, the aetiological condition (pain, fever, constipation, etc.) should be corrected. Such general measures as ensuring a peaceful, familiar environment, and the use of a night light, fluid therapy to counteract dehydration, and antipyretics for fever are beneficial. When symptomatic treatment is needed, drugs with little anticholinergic effect are to be recommended. The use of benzodiazepines as single drug treatment may exacerbate the condition. Haloperidol or risperidone (which has fewer side effects) are recommended. If the agitation is marked, a common strategy is to add lorazepam. Chlormethiazole is an alternative. Subcutaneous midazolam should be reserved for refractory cases. Attention should be paid to dosage, reduced doses being given to the elderly, patients on opioid medication, and patients with impaired liver or renal function. Overdosage may induce deep sedation, and result in carbon dioxide retention and subsequently heart failure and pulmonary oedema which may be fatal.

For pure childhood absence epilepsy (CAE), ethosuximide (ESM) remains the drug of first choice. Although valproic acid (VPA) is of equal efficacy, it is more toxic, and is reserved for those patients with accompanying convulsions. Lamotrigine (LTG) is effective as both add-on and monotherapy for CAE. If any of these three drugs fails, one of the other two can be used as monotherapy. Rarely, when ESM, VPA, or LTG does not effectively control CAE, phenytoin (PHT), primidone (PRM), and phenobarbital (PB) may be partially effective, although carbamazepine (CBZ) may worsen absence seizures. Experience is limited with the newer AEDs. Tiagabine (TGB) may induce absence status epilepticus in PGE. Oxcarbazepine (OXC) and vigabatrin (VGB) may worsen absence seizures. Felbamate (FBM) is probably effective, but is potentially fatal. Lifelong therapy is not anticipated. For juvenile absence epilepsy (JAE), VPA is the drug of first choice. LTG is also of proven efficacy. The risks of VPA-induced teratogenicity (possibly lessened by the concurrent use of folic acid) and weight gain are potentially unacceptable in young women of childbearing age. Not enough data exists on the safety of LTG in pregnancy. A combination of VPA and LTG can be used if either drug alone is unsuccessful. For juvenile myoclonic epilepsy (JME), VPA is the traditional drug of first choice in most patients. As in JAE, side effects may make VPA an unacceptable choice in many patients, especially young women. In clinical practice, TPM is being increasingly used as monotherapy for JME. Many patients appreciate the accompanying weight loss seen with TPM, but it has potentially troubling side effects, has not been well studied as monotherapy for JME, and its safety in pregnancy has yet to be confirmed. PHT and CBZ may worsen myoclonus when used alone, but they may have a role as add-on treatment to VPA, LTG, or TPM, especially when generalized tonic-clonic seizures (GTCSs) are not controlled. PB and PRM may also be useful as add-on treatment, but often have unacceptable side effects. Clonazepam may be useful as adjunctive treatment for resistant myoclonic jerks. OXC and VGB both worsen myoclonic seizures. GBP is not useful in JME and can make seizures worse. The efficacy of FBM and TGB in JME is largely unknown. Lifelong AED therapy is necessary. In epilepsy with generalized tonic-clonic seizure (GTCS) on awakening (EGA), VPA is the drug of choice, especially if other seizure types (absence and myoclonic) are present. If only GTCSs are present, then PB, PHT, and CBZ may be as effective as VPA; however, the use of PHT and CBZ may "unearth" other seizure types (absence and myoclonic) in those patients with EGA, although PB is poorly tolerated. As for JME, LTG, and TPM may both be effective monotherapy for EGA, although the use of other AEDs in EGA has not been well studied. Lifelong AED treatment is necessary.

Sedatives continue to be used on a routine basis in critically ill patients. Although many agents are available and some approach an ideal, none are perfect. Patients require continuous reassessment of their pain and need for sedation. Pathophysiologic abnormalities that cause agitation, confusion, or delirium must be identified and treated before unilateral administration of potent sedative agents that may mask potentially lethal insufficiencies. The routine use of standardized and validated sedation scales and monitors is needed. It is hoped that reliable objective monitors of patients' level of consciousness and comfort will be forthcoming. Each sedative agent discussed in this article seems to have a place in the ICU pharmacologic armamentarium to ensure the safe and comfortable delivery of care. Etomidate is an attractive agent for short-term use to provide the rapid onset and offset of sedation in critically ill patients who are at risk for hemodynamic instability but seem to need sedation or anesthesia to perform a procedure or manipulate the airway. Ketamine administered through intramuscular injection or intravenous infusion provides quick, intense analgesia and anesthesia and allows patients to tolerate limited but painful procedures. The risk/benefit ratio associated with the use of this neuroleptic agent must be weighed carefully. Ketamine is contraindicated in patients who lack normal intracranial compliance or who have significant myocardial ischemia. Barbiturates are reserved mainly to induce coma in patients at risk for severe CNS ischemia, which frequently is associated with refractory intracranial hypertension, or in patients with status epilepticus. When administered in high doses, these drugs have prolonged sedative and depressant effects. Judicious hemodynamic monitoring is required when barbiturate coma is induced. Haloperidol is indicated in the treatment of delirium. Patients should be monitored for extrapyramidal side effects and, when they require higher doses, for potential electrocardiographic prolongation of the QT interval. Dexmedetomidine may evolve into an agent with qualities comparable with midazolam and propofol, and it may even become a drug of choice in select patients. Further study is required, however. Propofol has many of the qualities of an ideal sedative agent. Benzodiazepines and narcotics often are used in concert with propofol to provide reliable amnesia and to relieve pain, respectively. Propofol frequently causes hypotension when administered as a bolus or infusion, particularly in patients with limited cardiac reserve or hypovolemia. More data must be obtained to identify potential deleterious effects of hypertriglyceridemia, and further evaluation of the potential benefits in certain patient populations, such as neurosurgical patients, is needed.

Acute symptomatic seizures and epilepsy are two of the most common neurologic complaints in the elderly. Stroke is the leading underlying etiology for both. Because clinical seizure manifestations in the elderly often differ from those in younger adults, they may be difficult to recognize or may be misdiagnosed. Interpretation of diagnostic tests in elderly patients with seizures is often complicated by comorbidities, and treatment decisions require careful consideration in the context of age-related physiologic changes, comorbidities, and the use of concomitant medications. Treatment of an acute seizure with a clear precipitating cause involves correcting the underlying etiology; antiepileptic drug (AED) therapy is generally reserved for patients with epilepsy (recurrent unprovoked seizures). The prognosis for elderly epilepsy patients treated with AEDs is generally good. Both older and newer AEDs are efficacious but have respective advantages and disadvantages; no ideal AED yet exists. Status epilepticus is a neurologic emergency that is particularly frequent in the elderly and associated with high mortality, although treatment can be effective.

Little to no pediatric or neurosurgical literature has been published about the complications of ventriculoperitoneal shunt procedures for hydrocephalus associated with vein of Galen malformations in childhood. The interventional neuroradiology literature, however, suggests that ventriculoperitoneal shunting as first-line treatment for hydrocephalus in children with vein of Galen malformations is fraught with short- and long-term dangers, including status epilepticus, intraventricular hemorrhage, subdural hematoma and hygroma, venous infarction, malignant dystrophic calcification, and worsening developmental delay. We present a single pediatric case where a ventriculoperitoneal shunt procedure for symptomatic hydrocephalus seemed to be the major contributing factor to the rapid neurological deterioration and eventual death of an infant with a vein of Galen malformation. Based on this experience and our review of the literature, we suggest the use of endovascular embolization of the vein of Galen malformation to reestablish a balance in hydrovenous dynamics as first-line treatment rather than directly addressing hydrocephalus with CSF diversion. The ventriculoperitoneal shunt procedure should be reserved for cases with symptomatic hydrocephalus in which the patient is a poor candidate for embolization, or for cases where endovascular therapy has already been maximized. The role of endoscopy in the treatment of hydrocephalus associated with vein of Galen malformations is not clear.

Continuous spikes and waves during sleep (CSWS) is an epileptic encephalopathy characterized in most patients by (1) difficult to control seizures, (2) interictal epileptiform activity that becomes prominent during sleep leading to an electroencephalogram (EEG) pattern of electrical status epilepticus in sleep (ESES), and (3) neurocognitive regression. In this paper, we will summarize current epidemiological, clinical, and EEG knowledge on CSWS and will provide suggestions for treatment. CSWS typically presents with seizures around 2-4 years of age. Neurocognitive regression occurs around 5-6 years of age, and it is accompanied by subacute worsening of EEG abnormalities and seizures. At approximately 6-9 years of age, there is a gradual resolution of seizures and EEG abnormalities, but the neurocognitive deficits persist in most patients. The cause of CSWS is unknown, but early developmental lesions play a major role in approximately half of the patients, and genetic associations have recently been described. High-dose benzodiazepines and corticosteroids have been successfully used to treat clinical and electroencephalographic features. Corticosteroids are often reserved for refractory disease because of adverse events. Valproate, ethosuximide, levetiracetam, sulthiame, and lamotrigine have been also used with some success. Epilepsy surgery may be considered in a few selected patients.

Dyke-Davidoff-Masson Syndrome (DDMS) is a rare neurological condition characterised by drug-resistance seizures, hemiparesis, mental retardation, facial asymmetry, and intellectual disabilities. On brain imaging, the disease is characterised by cerebral hemiatrophy with ipsilateral calvarial thickening and hyperpneumotisation of paranasal sinuses or mastoid air cells. Although more common in men and on the left side of the brain, the disease can affect both genders and cerebral hemispheres. It mainly presents in childhood. The adult presentation is unusual but has been reported in medical literature. Most of the patients need more than one antiepileptic agent for optimal control of seizures. Hemispherectomy is reserved for patients who have drug-resistant and disabling seizures. The good prognostic factors are disease onset before age of two and better seizure control. We report two cases of DDMS occurring in teenage boys who presented with status epilepticus. The clinical histories, radiological findings, and treatment of both patients are discussed below.
