EEG were recorded in 3,726 children, from 6 to 13 years of age who were neurologically normal and had no history of epileptic seizures. The records were taken during wakefulness, at rest, and during hyperventilation. In 131 cases (3.54%) epileptiform patterns were found. They consisted of 3 count/sec spike and slow waves discharges (4 cases), multiple spike and slow wave complexes (37 cases), midtemporal spikes (50 cases), rolandic or parietal spikes (27 cases), occipital spikes (2 cases), and multifocal spikes (11 cases). Half of the subjects with EEG abnormalities had behavior problems and/or slight psychomotor ability disturbances. Follow-up studies over an 8 to 9 year period were performed. These demonstrated the spontaneous disappearance of the EEG abnormalities, usually within school age or, at the latest, during adolesence. Only seven individuals developed epileptic seizures of the primary generalized type which responded well to anticonvulsant drug treatment. From this study we can deduce that the epileptiform EEG patterns that often are found in children during school age have no clinical relationship to epilepsy in the great majority of cases. The relationship with epilepsy exists probably on a genetic level for the generalized discharges. The spike foci are non-epileptic in nature in all probability, especially if they emerge from a fairly normal background activity and their duration is very similar to that of the constituents of the background activity, as found in the majority of these subjects. On the contrary, it is probable that these alterations express difficulties in affective or motor adaptation during childhood.

An epidemiologic study of epilepsy in school age children has been carried out in Modena, Italy, during the period 1968 to 1973. The prevalence of epileptics aged 5 to 14 years varied between 3.98% and 4.91%. The accession rate varied between 60 and 98 cases /100,000. The primary generalized epilepsies represent 30.8%, the epilepsies with rolandic spike foci 23.9%, the other types of partial epilepsy 42.1%, and the Lennox-Gastaut syndrome 3.2%. Of the 178 epileptics diagnosed during school age, 159 have been followed for at least 4 years, with recovery in 55% of the cases and tendency to improve in 24%.

Conclusions-Earlythrombosis may occur as a complication of umbilical catheterisation in preterm infants; early echocardiographic detection of this disorder allows complete, safe, and rapid lysis with rt-PA.

Epidemiological and genetic variables in clefts were analyzed during the years 1978-1986 in a case-control study of congenital malformations in the Emilia Romagna region of northern Italy. Among 150,168 newborns, 200 cases of cleft were detected, yielding a prevalence of 1.33 per 1,000. These clefts consisted of 112 (0.075%) cases of cleft lip with or without cleft palate (CL +/- P) and 88 cases (0.058%) of cleft palate (CP). Coexisting abnormalities were found in 32% of cases. The heritability coefficient of CL +/- P was 0.84. No cluster in time or space could be demonstrated. Epilepsy was the only maternal risk factor found to be correlated with clefts. A predominance of males was found among CL +/- P cases.

Absence epilepsy with multiple daily seizures and onset at the age of 6 and 1/2 months in a healthy female child with normal development is described. EEG-video recording revealed typical absence seizures (vacant staring and interruption of motor activity) and complex absences (as above, plus raising of the eyeballs, slight beatings of the eyebrows, and forward propulsion of head and shoulders). The absences were accompanied by bilateral symmetrical 3-Hz spike-wave discharges preceded, and at times followed, by bilateral frontoparietal theta activity coinciding with onset and termination of the absence seizures. The seizures regressed with nitrazepam therapy. At age 3-years, the child is seizure-free and shows normal neurologic development.
