The purpose of this study was to investigate the causes of food impaction and to explore solutions as well. For this study, 39 patients with food impaction wee selected. 77 contact areas in these patients were investigated mobility, tightness of contact area, gingival index, plaque index, attachment loss, alveolar bone loss, proximal caries, marginal ridge distance and occlusal relationships. The results were as follows ; 1. Teeth without distal support were found to be the most frequent site of food impaction (41.6%). Food impaction was found to be more frequent in the upper teeth (66.2%) than the lower teeth (33.8%). 2. Food impaction was found in tight contact cases (71.4%). Alveolar bone loss was not found in the early stage of food impaction (83.1%) 3. The distance between the marginal ridges of food impaction sites (mean=0.48mm) was shorter than that of the control group. (mean=0.77mm) (p<0.001) 4. In 18.2% of t he cases, proximal carries were found at the food impaction site. 5. Food impaction affected patient's occlusion with the following frequencies ; cusp to marginal ridge relationship (72.7%), cusp to fossa relationship (3.9%) and stepped relationship (23.4%).

A retrospective study was made of the previous medical records of 32 infants with congenital syphilis borne from mothers with untreated syphilis at Severence Hospital, Yonsei University College of Medicine during the years 1,972 through 19g3, These infants had a VDRL titer higher than 1: 8 with reactive FTA-ABS test and were also subjected to radiologic examinations. Radiologic changes and clinical features were analyzed, The following results were obtained: Of the total of 32 infants with congenital syphilis under 5 months of age, those under 1 month of age, were the most common group numbering a total of twelve. Of 32 infants with congenital syphilis, twenty-nine(91%) showed skeletal changes upon radiologic examination, Among them the different sites of bone involvernent revealed that the femur(92%) was the most commonly affected bone, followed by the humerus(88%), tibia(81%,), fibula(80%), ulna(72%), radius (68%). Among the same 29 infants a study of the presence of various abnormal bone changes showed that periostitis was the most common, being involved in 83%, the others being metaphysitis and periostitis(72%), metaphysitis(66%). 3. Among the clinicaI features presented in the 32 infants with congenital syphilis, hepatomegaly was the most common(63%,), followed by erythema with desquamation(47%), pneumonia(38%), maulopapules(34%).

The folling results were obtained through the clinical review and Virology Laboratory of 100 cases of meningitis seen at ward of the pediatric department of Has Sung Hospital during the period from May to June, 1993. 1) Early childhood period was the most frequent age group and male was predominant in aseptic meningitis. 2) The common chief complaints were fever, vomiting, headache in order. 3) On physical examination meningeal irritation signs were not prominent. 4) On admission, leukocytosis (WBC count>10.000/mm(3)) on peripheral blood was showed in 36%. 5) The findings of cerebrospinal fluid showed that cells (Mean WBC count 671.8/mm(3)) were increased in all cases, and protein and sugar were mostly within normal limit. 6) Echovirus 9 was thought to be main causative agent according to the cerebrospinal fluid culture and antibody test. 7) On follow up study 2 months after discharge, 14 cases showed minimal abnormalities of EEG but no abnormal finding in BERA.

Cardiac Arrest victims are increasing but EMS is not ready for them, in Korea. At this time, we need to know the exact status about the chain of survival of CPR and the outcome after out-of-hospital arrest. More than 90% of out-of-hospital arrest was witnessed, and about a half at home, but bystander CPR was done in only about 10%. EMS is activated by the unified phone number (119), but in only 1%, EMS was dispatched for CPR, nationwide. EMS responders were not educated and organized specific for CPR situation. BLS and equipped AED were not always utilized to whom needed. Pre-hospital ACLS were exceptionally done by first responder. Initial ECG findings, most of which were recorded at Hospital ED(more than 20 minutes after collapse), were VF/Pulseless VT(11-12%), Asystole(63-64%), and PEA(24-26%). Initial ROSC rate was 44-45%, and final Discharge Alive rate was 5-10%. The outcome of out-of-hospital arrest was dependent on bystander CPR and initial ECG finding. Most of lay-person are aware to CPR, but not adequately educated to do CPR when needed. We should organize the efforts to improve the quality of EMS and build up the education system of CPR nationwide, at now.
