It is widely blieved that the new bone formation is provoked by fine electrical stress to bone. There have been maay experimental studies that showed much efforts to define these small amounts of electricity, and these fine electricities are being used in the orthopedic field for the treatment of various fractures, nonunions and pseudsrthrosia The auther has checked the electrical potentials changing in the course of fractvre hesling in rabbits femur. Comparing these data with that of the normal control group, the following results were obtained. 1. In the normal rabbit's femur the electrical potentisl was 13.6mV less on the concave side than on the convex side. This finding can be explained by the existence of stress generated potential or piexoelectricity. 2. Electrcal potentials on the fractured femoral sites were lowered significantly from that of the control group. So auther could confirm the existence of bioelectrical generated by increased electrical activity of the living bone. 3. The electrical potential of the fractured femoral site has been decreased 50% and 20% as low as that of the normal site at 8 weeks respectively. It is expected that these lowered electrical potentials may become dose to the normal values when the changed metabolic process due to the fractured bone is no longer functioning and it is believed to take human 2 years to get the normal value.

Morphological changes of the kidney after ESWL in 130 patients are analyzed with CT at Dept. of Urology, Chung-Ang University Hospital from March 1987 to May 1987. Of 130 patients, 9 patients(6.9%) showed renal hematoma. Among 9 patients, 5 patients (3.8%) had subcapsular hematoma and 4 patients(3.1%) had parenchymal hematoma. We analyzed these 9 patients radiologically and clinically. These hematoma were clinically insignificant and self-limited in all cases. So ESWL can be regarded as a safe modality for treatment of the renal and ureteral calculi.

Although many improvements have been made in surgical technique, as well as preoperative and postoperative care, the pancreaticoduodenectomy remains a technically difficult procedure attended by relatively high morbidity and mortality rates. This study concerns a total of 43 patients that underwent a pancreaticojejunostomy using a polyethylene stent by the Dunking method in a pancreaticoduodenectomy at Soon Chun Hyang University Hospital from January 1990 to December 1996. The results obtained are as follows:1) In our study, there were 13 patients with pancreatic head cancer, 11 patients with ampulla of Vater cancer, 5 patients with distal common bile duct cancer, 4 patients with duodenal cancer, 3 patients with chronic pancreatitis, 3 patients with trauma, 3 patients with a choledochal cyst, 1 patient with stomach cancer. 2) There were 23 men (53.5%) and 20 women (46.5%). 3) Postoperative complications developed in 25 patients (58.1%). Of the complications, bleeding was the most commonly observed, after which, in order of frequency, wound infection, leakage at the anastomotic site, intestinal obstruction, and intraabdominal abscess were also observed. 4) The overall operative mortality was 13.9% (excluding emergency cases, mortality was 7.5 %). Four patients died of intraabdominal or gastrointestinal bleeding, one patient died of pancreatic leakage, and one of hepatic failure. 5) Transfusion during the operation (above 5 pints) was significantly correlated with operative morbidity. Preoperative percutaneous transhepatic biliary drainage (PTBD) with serum bilirubin greater than 10 mg/dl significantly decreased the operative morbidity. 6) A prothrombin time more than 13.9 second, serum albumin less than 3.0 g/dl, and an emergency operation were significantly correlated with operative mortality.

Diffuse telangiectatic type of pulmonary arteriovenous malformation (AVM) is an uncommon disease entity in which numerous small arteriovenous connections occur throughout the lungs. It has rarely been confirmed by pulmonary angiography. We report a case of diffuse telangiectatic pulmonary AVM occurring in a patient with dyspnea and confirmed by CT using the slab maximum intensity projection (MIP) technique and conventional direct pulmonary angiography.

The pathogenesis of thrombocytopenia in the gestational thrombocytopenia is not understood.This syndrome may represent either the de novo development of ITP or an accelerationof the physiologic pattern of increased platelet destruction that occurs during gestation. Thisdisorder is not easily distinguishable from classical ITP. However, the recognition and diagnosisof this syndrome is important because infants born to individuals with gestational thrombocytopeniaappear to have a markedly reduced risk of developing thrombocytopenia when comparedto infants born to patients with a history of ITP antedating pregnancy. We represent a caseof delivery in severe gestational thrombocytopenia with brief review of the literature.

Most osteosarcomas arise spontaneously, but rarely they may be secondary to other benign osseous conditions and may occur following irradiation. Postradiation sarcoma of bone is approximately 5.5 percent of all osteogenic sarcoma. Diagnosis is possible when a sarcoma arising after long latent period(more than 3 years) in irradiated bone and the bone is normal or benign osseous lesion at the time of irradiation. The spontaneously arising osteogenic sarcomas are distribute mainly in the knee region, but postradiation sarcoma arise in any bones, such as long bone of the extremity, pelvic bone, vertebra, craniofacial bone and shoulder girdle bone. Recently we experienced a case of postradiation osteosarcoma of the pelvic bone who received radiation therapy for carcinoma of the uterine cervix 20 years ago.

BACKROUND: Polymorphism of glycoprotein IIIa on human platelets is one of the factors in alloimmunization that causes neonatal alloimmune thrombocytopenia (NATP), and the granulocyte antigens NA1 and NA2 are often targets of granulocytes antibodies causing neonatal alloimmune neutropenia (NANP). Currently, serotyping relies on the properties of the typing sera or antibodies and technique used. Genotyping circumvents the problems associated with serotyping. METHODS: The genomic DNA of 200 unrelated pregnant women admitted to Taegu Fatima Hospital was typed for three platelet glycoprotein IIIa-specific antigens (HPA-1, HPA-4, and HPA-6w) and granulocyte antigens (NA1 and NA2). Allele specific amplification test using primer designed to study HPA-1 and HPA-4, restriction fragment length polymorphism to study HPA-6w, and sequence specific primers for NA1 and NA2 were used for genotyping. RESULTS: The genotype frequencies were HPA-1(a+b-) 100%, HPA-4 (a+b-) 97.5%, HPA-4(a+b+) 2.5%, HPA-6w(a+b-) 97%, and HPA-6w(a+b+) 3%. These frequencies are similar to Japanese but different from Caucasian. The gene frequencies of NA1 and NA2 were 0.56 and 0.44 respectively. There are no cases of alloimmune thrombocytopenia and neutropenia in newborns from the 200 studied women. CONCLUSIONS: The differences in genotype frequencies among platelet glycoprotein IIIa-specific antigens and in the gene frequencies of NA in Koreans are shown as compared with other ethnic groups. Therefore it is needed to find the proper screening target antigens and antibodies for Korean NATP and NANP patients.

PURPOSE: The purpose of this study was to evaluate the appropriateness of prehospital emergency care by 119 rescue services in Seoul. METHODS: We enrolled all patients who used 119 rescue services in Seoul between January and Sepember 2006 and analyzed the 119 ambulance patient care record databases. Major emergencies were defined and categorized into four groups: cardiopulmonary complaint (CP), neurologic complaint (NR), cardiorespiratory arrest (CA) and major trauma (MT). Interventions provided by emergency medical technicians were scored as 2:essential, 1:optional and 0:unnecessary in each category of major emergency. We summed scores of provided interventions per patient and graded them into four levels for conducting the appropriateness review. Multivariate logistic regression analysis was performed to determine the relationship of risk factors to the appropriateness of intervention. RESULTS: Total number of cases was 171,112 of which 36,065 were major emergencies. The proportion of "very low" level appropriate was 40.1% for CP (N=11,522). 49.3% for NR (N=15,239), 14.5% for CA (N=1,591), and 32.7% for MT (N=7,713). The proportion of "high" level was less than 3% except for CA(11.3%). Variables affecting the "moderate" or "high" level of appropriateness of prehospital emergency care, as determined by multivariate logistic regression analysis, were age > or =65(OR: 1.425, 95% CI: 1.337-1.520), female gender (OR: 0.880, 95% CI: 0.828-0.935), and type of complaint in the order CP (OR: 0.181, 95% CI: 0.161-0.204), NR (OR: 0.184, 95% CI: 0.164-0.207), and MT (OR: 0.202, 95% CI: 0.178-0.229). CONCLUSION: The prehospital emergency care of 119 rescue services in Seoul was frequently inappropriate and was influenced by patient's age, gender and chief complaints.
