Abstract |
This study was undertaken to evaluate the electronencephalographic and clinical findings in 132
cases of encephalitis and encephalopathy in the Department of Pediatrics, Kyung Hee University
Hospital for 9 years from Jan. 1979 to Dec. 1987.
The results were summerized as follows;
1) The incidence of ecephalitis was 0.46%{86 cases) and the incidence of encephalopathy was 0.25
% (46 cases) among total in-patient (18,671).
2) Male to female ratio was 1.6:1 in encephalitis and 1.3:1 encephalopathy and the peak age was 2
to 6 years in both.
3) Autumn was the most prevalent season (45.3% in encephalitis and 37.0% in encephalopathy) and
late summer was the 2nd most common (2.3% in encephalitis and 19.6% in encephalopathy).
4) In etiologies, unknown cases were 58.1 % in ecephalitis and 73.9% in encephalopathy and
Japanese B encepahlitis was the most common cause (23.2%) among the known etiologies of encepha.
litis.
5) In clinical symptoms and signs,
Encephalitis; changes of consciousness (91.9%), seizure (67.4%), fever (58.1%)'"
Encephalopathy; changes of consciousness (95.7%), seizure (76.1%), fever (58.7%)'"
이 CSF pleocytosis was found in 96.2% of encephalitis but not in all of encephalopathy and CSF
protein values were elevated in 50.6% of ecephalitis and only in 18.6% of encephalopathy and CSF
glucose value was decreased in 30.4% of encephalitis and 23.2% of encephalopathy.
7) In brain CT findings,
Encephalitis; unremarkable findings (30.5%), brain swelling (30.5%), low density (16.7%)' "
Encephalopathy; unremarkable findings (43.5%), brain swelling (30.4%), low density (13.0%) .. '
8) In the EEG findings, abnormal EEG findings was observed in 81.8 of encephalitis and 81.0% of
encephalopathy.
9) In the relationship between EEG findings and prognosis, mortality rate was 11.4% in patients
with abnormal EEG findings on admission and the highest mortality rate was observed in patients
with EEG findings of suppression pattern among the abnormal EEG findings on admission{50.0%). |
