One hundred seven consecutive patients aged 3 years to 34 years with simple ventricular septal defect were prospectively investigated with 2-dimensional Doppler echocardiography to assess the echocardiographic criteriae in defining the anatomic site of the VSD. The anatomy was confirmed in all patients at operation. Two-dimensional Doppler echocardiography correctly categorized the site and extension of VSDs in 104 of 107(97%). All doubly committed subarterial VSDs were correctly diagnosed as an area of discontinuity beneath the pulmonary valve in the parasternal short-axis plane taken at the aortic root level. Forty eight of 49 perimembranous VSDs with infundibular extension showed an area of discontinuity beneath the right aortic cusp in the parasternal long axis plane of the left ventricle. Of 17 perimembranous VSDs with trabecular extension, 16 had an area of discontinuity around the medial papillary muscle in the short axis plane taken at the level of high left ventricular outflow tract(LVOT). All 5 perimembranous VSDs with inlet extension showed an area of discontinuity adjacent to the septal leaflet attachment in the short axis plane taken at the level of high LVOT. One muscular trabecular VSD was categorized correctly by the short axis view and the apical 4-chamber view. Thus, these 2-dimensional Doppler echocardiographic criteriae are a simple and reliable in identifying the anatomic site of VSDs.

This study consisted of 66 peritrochanteric fractures which were treated by the modified Gamma nail (Asian Pacific nail) from August 1993 to October 1995. Sixty-one intertrochanteric fractures and five subtrochanteric fractures were treated in our institution. Average length of follow-up was 15.0 months. Four patients died during follow-up. The results were as follows; Lag screws were ideally introduced in 55 (83%) cases. The mean length in lag screw sliding was 4.3 mm in stable trochanteric fractures and 5.7 mm in unstable ones. Fifty-one out of 62 patients (82%) were returned to their previous ambulatory status. Intraoperative complications were as follows; distal crack (3 cases); rotation of femoral head (2 cases); entry point crack (I case); medialization of proximal fragment (7 cases); and missing of the interlocking screw (1 case). All of these complications did not affect the outcome. All medial cortical gaps were closed after sliding of lag screws. Three distal cracks did not propagate to the shaft. Postoperative complications were a case of superior cut-out, and two second fractures after falls. Callus formed more early in the stable trochanteric fractures (5+/-2.1 weeks) than unstable fractures (7.3+/-2.1 weeks). It was statistically significant. Union time between stable and unstable trochanteric fractures was not statistically significant. In conclusion, the Asian Pacific (AP) nail could appropriately fix the osteoporotic peritrochanteric fractures in elderly patient. It could offer early rehabilitation to these patients and decrease the mortality and morbidity.

The author observed clinical study and response of -interferon treatment of 43 cases of chronic hepatitis who were admitted to Department of Pediatrics Pusan National University College of Medicine during the period of 4 year 6 months from Jenuary, 1988 to Jun, 1992. The results were as follows: 1) Of 43 patients with chronic hepatitis, CPH was 17 cases (39.5%) and CAH was 26 cases (60.5%). 2) Of 43 patients, chronic hepatitis caused by HBV was 37 cases (86.0%) 2 cases were by Wilson's disease, 1 case was by glycogen storage disease and in the 3 cases, the cause was undetermined and CPH by HBV and CAH were 14 cases (82.4%), 23 cases (88.5%) respectively. 3) A peak frequency (46.5%) of chronic hepatitis occurred between 6 to age and male predominated in a propotion of 3.5:1. 4) On the clinical manifestation, jaundice and hepatomegaly was higher frequency on CAH than on CPH. 5) On the laboratory findings, CAH had higher serum ALT and direct bilirubin level than CPH. 6) On effect of -interferon treatment for patients of CAH, serum ALT and AST levels normalized in 81.8% of patients, negative conversion of HBeAg was 38.5%, Anti-HBe serocoversion was 7.7%, negative conversion of HBsAg was 7.7% and the clearnce of HBV-DNA from seum showed 60.0%. 7) The HBeAg seroconversion (28.6%) on children of HBsAg(+) mother showed lower reponse than HBeAg seroconversion (50.0%) of HBsAg(-) mother after -interferon treatment for patients of CAH.

Visualization of falx cerebri on non-enhanced CT of children with severe head injuries (the falx sign) has been regarded as an evidence of subarachnoid hemorrhage. On the contrary, other authors have reported reverse results. To evaluate clinical significance of the falx sign, authors studied frequency of visualization and CT number of falx cerebri and dural sinuses in 65 children with head injury and 65 children without head injury examined by cranial CT at the Dep. of Radiology, St. Paul's Hospital, Catholic Medical College from March to Sept. 1981. All patients with head trauma were studied within 1 week of the traumatic event. Visualization of falx cerebri was observed at slice in the region of lateral ventricle and slice near to vertex respectively. On the slice in the region of lateral ventricle, falx cerebri was identified in 82% of all of the children examined, of which 92%showed partial visualization of falx cerebri and remaining 8% totally. On the slice near to vertex, falx cerebri was identified in 92% of all the children examined, of which 38% showed partial visualization of falx cerebri and remaining 62% totally. In head trauma group, frequency of visualization of falx cerebri was 78% on the slice in the region of lateral ventricle and 89% on the slice near to vertex; in non-traumatic group, frequency of visualization of falx cerebri was 86% and 94% respectively. The highest numerical value of the falx densities averaged 47 Hounflieds (range, 32-63) in non-traumataic group, averaged 49 Housfields (range, 32-69) in head trauma group. All or a portion of the superior sagittal sinus was visualized in 59% of all of the cases studied, 50% in head trauma group, and 69% in nontraumatic group. The straight sinus was identified in 45% of all of the cases studied, 39% in head trauma group, and 51% in non-traumatic group. In conclusion, there was no distinction between head trauma and non-traumatic group in visualization of falx cerebri and dural sinuses, and we could frequently identify the falx density in normal. Also we could find that frequency for visualization of falx cerebri and drual sinuses increased as the age increased.
