Lennox-Gastaut syndrome is an epileptic encephalopathy characterized by multiple seizure types, mental retardation, and a slow spike-and-wave pattern on electroencephalography. Medical intractability is common. We identified a case series of six patients diagnosed with Lennox-Gastaut syndrome in which levetiracetam was initiated as add-on therapy for the management of seizures. At follow-up, four patients experienced 100% reduction of their myoclonic seizures; two patients had greater than 50% reduction of their atonic seizures, and four patients experienced 100% reduction in their generalized tonic-clonic seizures. Tonic seizures were not responsive to treatment. The most common side effect was irritability; the most positive change involved alertness. In this small sample, levetiracetam appeared effective in reducing seizures in Lennox-Gastaut syndrome. This preliminary study is limited by its retrospective design and small number of patients, but positive findings warrant a larger scale, multicenter study.

The Wada test has historically been the conventional procedure for determining language lateralization before neurosurgery. However, functional magnetic resonance imaging (fMRI) offers a less invasive alternative to the Wada procedure. Research indicates that the two techniques used together may provide comparable, and sometimes complementary, information that results in improved prediction of postsurgical language ability. We present a case in which use of fMRI in conjunction with Wada testing provided complementary information about language lateralization before neurosurgical resection of a mesial temporal subependymoma for seizure control in a patient with schizencephaly.

Objective: To compare subjective parental perceptions of short-term diabetes control with objective glycated hemoglobin (HbA1c) measurements in a pediatric population., Methods: Parents of 159 children and adolescents with type 1 diabetes anonymously completed a questionnaire concerning demographics, parental perception of the child's recent glycemic control, concern about nocturnal blood glucose levels, and factors related to severity of the child's diabetes. Nonparametric correlations were performed among all variables and the child's current HbA1c measurement. Good short-term glycemic control was defined as an HbA1c value of < or = 8.5%., Results: Five factors were found to correlate significantly with good glycemic control, and these variables were subjected to a logistic regression analysis. With use of a cutoff value of 0.58, results explained 26% of the variance and had an overall 71% correct classification rate. Children with good glycemic control were younger, had a shorter duration of diabetes, lived in families with higher socioeconomic status, were less likely to experience hospitalizations due to their diabetes, and had parents who "always worried" about nocturnal blood glucose variations. Parental perception and HbA1c values were not significantly related (P>0.19); 60% of the parents correctly perceived the status of diabetes in their children, and 40% misperceived the level of glycemic control. Further analysis suggested that accuracy of parental perception was highly dependent on the child's level of glycemic control. Parents whose children had lower HbA1c values (< or = 7.5%) correctly perceived the status of blood glucose control in their children, whereas parents whose children had poorer glycemic control (HbA1c > or = 9.5%) had inaccurate perceptions., Conclusion: Subjective parental perceptions of diabetes control in their children may not correspond to objective assessments. Our findings suggest a need for more educational feedback concerning HbA1c levels and recommended goals for glycemic control.
