Therapeutic hypothermia is the recommended treatment for neonates with moderate or severe hypoxic ischemic encephalopathy (HIE). There is an increasing trend to use therapeutic hypothermia even in infants with mild hypoxic ischemic encephalopathy, even though there is little evidence to support/refute this. ⋯ A significant proportion of infants who received therapeutic hypothermia had mild hypoxic ischemic encephalopathy. Randomized trials are urgently needed to evaluate the efficacy and safety of therapeutic hypothermia in infants with mild hypoxic ischemic encephalopathy.

Review Case Reports
Reversible Cerebral Vasoconstriction Syndrome in Pediatrics: A Case Series and Review.
Reversible cerebral vasoconstriction syndrome is a transient vasculopathy associated with severe headaches and stroke. In most cases of reversible cerebral vasoconstriction syndrome, there is a precipitating event or trigger, such as pregnancy, serotonin agonist treatment or illicit drug use. The authors present 2 pediatric cases of reversible cerebral vasoconstriction syndrome and review the previous 11 pediatric cases in the literature. ⋯ In the pediatric group, reported potential triggers include trauma (1/13), exercise (2/13), water to the face (3/13), hypertension (3/13), and medication or substance use (4/13). One surprising difference is that 11 out of 13 pediatric patients with reversible cerebral vasoconstriction syndrome are male while most cases in adults are female. Many of the pediatric patients with reversible cerebral vasoconstriction syndrome were treated with a calcium channel blocker and the overall outcome of pediatric reversible cerebral vasoconstriction syndrome was good, with most patients experiencing a full recovery.

Review Case Reports
Internal Carotid Artery Pseudoaneurysm and Ischemic Stroke Secondary to Retropharyngeal and Parapharyngeal Abscess.
Internal carotid artery pseudoaneurysm is an uncommon complication of retropharyngeal and parapharyngeal abscess in children. Treatment of the pseudoaneurysm has evolved in recent years from surgical ligation to endovascular techniques. Neurologic sequelae most commonly consist of Horner's syndrome with cerebral ischemia being uncommon. ⋯ A conventional angiogram confirmed the presence of a large pseudoaneurysm with no anterograde flow distal to the pseudoaneurysm and substantial collateral flow across the circle of Willis, with filling of the left anterior and middle cerebral arteries via the anterior and posterior communicating arteries. Endovascular occlusion resulted in nonfilling of the left internal carotid artery, pseudoaneurysm, and left internal jugular vein at the base of the skull. Following the procedure, the patient developed transient mild right hemiparesis associated with frontal lobe ischemia.

There are indications that preexisting mitochondrial disorders or beta-oxidation defects predispose for propofol infusion syndrome. This review aimed at investigating if propofol infusion syndrome occurs exclusively in patients with mitochondrial disorder and if propofol can unmask a mitochondrial disorder. Propofol infusion syndrome has been reported in genetically confirmed mitochondrial disorder patients. ⋯ Not only does propofol infusion syndrome occur in mitochondrial disorder patients, but mitochondrial disorder patients are likely at higher risk to develop propofol infusion syndrome. Patients who develop propofol infusion syndrome should be screened for mitochondrial disorder. Propofol infusion syndrome is preventable if risk factors are thoroughly assessed, and if long-term propofol is avoided in patients at risk for propofol infusion syndrome.

Review Meta Analysis Comparative Study
A Comparison of Midazolam, Lorazepam, and Diazepam for the Treatment of Status Epilepticus in Children: A Network Meta-analysis.
Midazolam, lorazepam, and diazepam were recommended as emergent initial therapy for status epilepticus. However, there are no current studies to confirm the best agent for pediatric status epilepticus. We compared the efficacy of midazolam, lorazepam, and diazepam in treating pediatric status epilepticus using a network meta-analysis method. ⋯ Nonintravenous midazolam, intravenous lorazepam, and intravenous diazepam were more successful in achieving seizure cessation when compared with nonintravenous diazepam (odds ratio = 2.23, 95% credibility interval: 1.62, 3.10; odds ratio = 2.71, 95% credibility interval: 1.25, 5.89; odds ratio = 2.65, 95% credibility interval: 1.12, 6.29; respectively). Among lorazepam, midazolam, and diazepam, midazolam had the highest probability (surface under the cumulative ranking area [SUCRA] = 0.792) of achieving seizure cessation, and lorazepam had the largest probability (surface under the cumulative ranking area = 0.4346) of being the best treatment in reduction of respiratory depression. In conclusion, nonintravenous midazolam and intravenous lorazepam were superior to intravenous or nonintravenous diazepam, and intravenous lorazepam was at least as effective as nonintravenous midazolam in treating pediatric status epilepticus.
