PURPOSE: Periodic lateralized epileptiform discharges (PLEDs), initially described by Chatrian et al in 1964, are an EEG phenomenon characterized by lateralized or focal spike-and-wave complexes with moderate to high voltage which occur in a periodic or semiperiodic pattern. This study was performed to assess the clinical significance of PLEDs and its relation to an imaging study of the brain. MEHTODS: Twenty children (10 males and 10 females), from 2 days to 14 years of age, who had been hospitalized at Hanyang University Hospital were studied retrospectively. Their medical records, EEG results and brain imaging study were reviewed. RESULTS: Of the 20 patients studied, 15 patients showed unilateral PLEDs and 5 had bilateral PLEDs in EEG. Brain imaging studies were done for 18 of the patients, revealing abnormalities in 15 patients in this order of frequency: intracranial hemorrhage, diffuse cerebral atrophy, leukomalacia, cerebral infarctions, cerebral edema and hydrocephalus. PLED sites were not significantly correlated with the results of the imaging study. Finally, 3 patients died and 17 patients survived, and among the surviving 17 patients, 5 had recurrent seizures, 1 had recurrent seizures with mental regression, 3 had neurologic sequelae without seizures and 8 had no neurologic sequelae. CONCLUSION: We conclude that children who show PLEDs in EEG are more commonly associated with acute cerebral lesions and there is a high incidence of subsequent seizures and/or other neurological sequelae in surviving children with PLEDs.

This study aimed to measure the thickness of the epithelium and lamina propria of the palatal mucosa and to elucidate the location of the greater palatine artery to provide the anatomical basis for subepithelial connective tissue grafting. Thirty-two maxillary specimens, taken from the canine distal area to the first molar distal area, were embedded in paraffin and stained with hematoxylin-eosin. The thickness of the epithelium and lamina propria of the palatal mucosa was measured at three positions on these specimens, starting from 3 mm below the alveolar crest and in 3-mm intervals. The location of the greater palatine artery was evaluated by using image-processing software. The mean epithelial thickness decreased significantly in the posterior teeth; it was 0.41, 0.36, 0.32, and 0.30 mm in the canine, first premolar, second premolar, and first molar distal areas, respectively. The lamina propria was significantly thicker in the canine distal; it was 1.36, 1.08, 1.09, and 1.05 mm, respectively. The mean length from the alveolar crest to the greater palatine artery increased toward the posterior molar; it was 7.76, 9.21, 10.93, and 11.28 mm, respectively. The mean depth from the surface of the palatal mucosa to the greater palatine artery decreased from the canine distal to the first premolar distal but increased again toward the posterior molar; it was 3.97, 3.09, 3.58, and 5.50 mm, respectively. Detailed histological assessments of the lamina propria of the palatal mucosa and the greater palatine artery are expected to provide useful anatomical guidelines for subepithelial connective tissue grafting.
