The sorption and desorption properties of four adsorbents were evaluated for the trace enrichment of clobazam from biological samples. Graphitized carbon black(GCB) gaved the highest dynamic adsorption coefficient. Among the six organic solvents examined, acetone gave the highest desorption coefficient for the clobazam adsorbed on GCB. Using the GCB column, the optimum elution volume of the eluting solvent was evaluated from the on-line monitored breakthrough curve for clobazam. When GCB as the solid adsorbent and acetone as the eluting solvent were used for the solidphase extraction of clobazam from serum, the recoveries were higher than 83% with good reproducibility in the concentration range of 20-50 $\mu\textrm{g}$/ml.

Hyperekplexia or startle disease is a hereditary neurological disorder characterized by an abnormally exaggerated startle response to tactile, auditory and visual stimuli, together with a global muscular hypertonia and hyperactive tendon reflexes. This disease is a rare, genetically determined disorder, with an autosomal dominant inheritance with variable expression, first described by Suhren, et al. We report two cases of familial hyperekplexia, who developed hypertonia and pathologic startle response to tactile stimulation in the immediate neonatal period. The infant showed a marked improvement of the startle response and muscular hypertonia with low-dose clobazam.

Angelman syndrome is a rare disorder caused by deletion or inactivation of genes on the maternally inherited chromosome 15. This neurodevelopmental disorder is characterized by developmental and intellectual delay, speech impairment, sleep disturbance, seizures, motor dysfunction, and frequent laughing or smiling. Orofacial characteristics include a prominent mandible, large mouth, prominent cheeks, a tendency to rest the tongue between the dental arches, excessive drooling, and excessive chewing behavior. Patients with this syndrome usually require general anesthesia even in a simple operation, because of risk of perioperative seizure during dental procedure. This is a case report about dental treatment of a 3-year-old female patient with Angelman syndrome under general anesthesia. This case suggests that the dental treatment under general anesthesia can be considered a safe component for the uncooperative, delayed developmental patients with underlying disease. Also, periodic dental exam appointment should be made to provide the patients with preventive treatments and to make them remain familiar with the dental environment.
