We have experienced 11 cases of large bony defect that were treated using microsurgery since 1981. Free vascularized bone transplantation was performed in 8 of them, vascularized bone transposition in 2 cases, and free vascularized joint transplantation in the remaining 1 case. The causes of the large bony defect were primary bone tumor (4 cases), congenital pseudoarthrosis (3 cases), open comminuted fracture (2 cases), sequela of osteomyelitis (1 case), and post-traumatic ankylosis of PIP joint of second finger (1 case). As a donor, fibula was used in 8 cases, iliac crest in 1 case, rib in 1 case and in the remaining 1 case, the second M-P joint of foot was transplanted. In 9 of 11 cases, successful result was obtained and 2 cases were failed because of vascular damage following tibial lengthening in one case and infection on the grafted area in the other one. From the above data and review of articles, following conclusions were obtained. 1. Fibula is thought to be the most appropriate donor for the large bony defect in the extremity, especially in lower extremity, but the donor site must be determined according to the anatomical and physilogical condition of the patient. 2. After mechanical lengthening of the extremity, it is recommened to perform the microvascular surgery after sufficient time for the recovery of vascular damage. But further studies are required for the identification of the change in the vascular tissue following stretching and its recovery time. 3. Progression of the ossification in the epiphysis of transplanted iliac crest was observed and this finding proposed us the idea that the epiphyseal plate injury or leg length discrepancy will be able to be treated with free vascularized epiphyseal plate transplantation and the reconstruction of the destroyed joint of growing children will be possible using free vascularized joint transplantation. 4. As the technique become more popular, the free vascularized bone transplantation is being used for the reconstruction of the extremity more frequently, but it seems to be wise to restrict its indication to cases which are impossible to be treated with more simple methods such as vascularized bone transposition or pedicled bone graft.

Choledochal cyst of the common bile duct is usually considered to be large cystic dilatation that extends from the wall of the common bile duct. Choledochal cyst is a very rare cond.ition in adult, These cysts are commonly distinctive in childran under the age of ten. Even in this age group they are considered rare. The classicajl triad of a choledochal cyst inclule pain, jaundice and a palpable right upper quadrant mass. This triad was found in only 21~63% and the most common finding is jaundice. Diagnoais of choledochal cyst usually is made during laparotomy, In nonjaundiced patients, oral cholangiogram and/or intravenous cholangiogram may yield the diagnosis. In jaundiced patiente where the diagnosis may be more difficult to make, one may consider doing ERCP and/or percutaneous transhepatic cholangiogram. The percutaneous transhepatic cholangiogram seems to be very helpful in diagnosing jaundiced patients. It is being used more and more in recent years but this method is not without complication. With advent of ERCP, visualization of the biliary tree has become a simple procedure when performed by expert endoscopists. To our knowlege, no previous case of choledochal cyst diagnosed by ERCP has been reported. yet in our country This paper reports 4 cases of choledochal cyst diagnosed by ERCP.

OBJECTIVES: To predict of the survival of patients with epithelial ovarian cancer, multivariable analysis was done to identify variables with independent prognostic factors. Based on materials from 191 clinical trials performed by Department of Obstetrics and Gynecology, Hanyang University Hospital, we constructed a prognostic index (Pp with considerable predictive power for long-term survival of patients with epithelial ovatian cancer treated with cis-platin based combination chemotherapy, METHODS: On identifying variables with independent prognostic value, statistical analysis were performed with clinicopathologic variables including age, FIGO stage, histologic subtype, histologic grade, residual tumor, presence of ascites, pretreatment levels of hemoglobin, platelet, and tumor markers(CA 125, CA 19-9). We also analyzed biological variables using immunohistochemical staining for GST-pie (glutathione-s-transferase-pie), p-glycoprotein, and MT (metallothinein) as a drug resistance and uPA (urokinase type plasminogen activator), PAI-1 (plasminogen activator inhibitor-l), nm23 (nonmetastatic gene 23) as a tumor invasion and metastasis. In addition, univariable analysis was performed followed by multivariable analysis using Coxs proportional hazards model to identify variables predictive of poor prognosis. Prognostic index (PI) was calculated based on sum of individual beta-coefficient of the most important independent prognostic value. RESULTS: With univariable analysis, age, FIGO stage, histologic grade, histologic subtype, presence of ascites, residual tumor, initial value of CA 125, MT, uPA, and PAI-1 were found to predict of patients survival. In the multivariable analysis and proportional hazard model, the pretreatment characteristics needed for the calculation of the PI are the age, the site of metastases expressed as stage, the histologic subtype, the size of residual tumor, the histological grade, and the presence of ascites. In the subgroup comprising the 10% of the patients with the best prognosis, 5-year survival rate was 78.9%, whereas in the subgmup comprising the 10% with the poorest prognosis, 5-year survival rate was 7.1%, which illustrates the large variability of the prognosis among patients. CONCLUSIONS: The PI was found to retain its value after response was achieved. The information provided by the PI can be expected to be useful in treatment planning and the proper stratification of patients in clinical trials.

Twenty six cases of borderline ovarian tumor(BOT) were treated between Jan. 1985 and Dec. 1997 at the Department of Obstetrics and Gynecology, Hanyang University. The clinical records were reviewed for all patients including histopathology, clinical features, and follow-up. The frequency of BOT was 12%(26/214) of epithelial ovarian malignancies, and patients with these tumors tend to present at a younger age(36 yrs) than those with invasive carcinomas. In terms of histologic type, mucinous type(21/26: 81%) were more prevalent than serous tumor(5/21: 19%) in this study. The positive rate of CA 125 was 20% in serous, and the positive rate of CA 19-9 was 24% in mucinous tumor. The size of mucinous was larger than that of serous tumors(17.1 cm vs 9,3 cm). Almost all of these tumor categorized as early stage(stage I: 96%), however, only one patient with serous tumor had advanced stage of disease(stage III: 4%), Therefore BOT tend to be diagnosed as earlier than invasive carcinoma. About 2/3 of patients were treated as conservative surgery(unilateral salpingooophorectomy or enuclation). Postoperative adjuvant chemotherapy was not given about half of cases(13/26). Median follow-up was 43 months and recurrent case was found only one in serous tumor, All patients in this study are still alive and free of disease except one, 5-year survival rate was 100%. But large number of study and long-term follow-up are needed to make a decision to treat and manage of BOT.

Military personnel often use ammunitions that contain lead. The present study aimed to identify the risks for lead exposure and lead poisoning among workers at indoor firing ranges. A special health examination, including blood lead level (BLL) testing, was performed for all 120 workers at the indoor firing ranges of the Republic of Korea's Air Force, Navy, and Armed Forces Athletic Corps. The overall mean BLL was 11.3 ± 9.4 µg/dL (range: 2.0-64.0 µg/dL). The arithmetic mean of the BLL for professional shooters belong to Armed Forces Athletic Corps was 14.0 ± 8.3 µg/dL, while those of shooting range managers and shooting range supervisors were 13.8 ± 11.1 µg/dL and 6.4 ± 3.1 µg/dL, respectively. One individual had a BLL of 64 µg/dL, and ultimately completed chelation treatment (with CaNa2-ethylenediaminetetraacetic acid) without any adverse effects. These findings indicate that indoor firing range workers are exposed to elevated levels of lead. Therefore, when constructing an indoor firing range, a specialist should be engaged to design and assess the ventilation system; and safety guidelines regarding ammunition and waste handling must be mandatory. Moreover, workplace environmental monitoring should be implemented for indoor firing ranges, and the workers should undergo regularly scheduled special health examinations.

PURPOSE: The 2010 guidelines for cardiopulmonary resuscitation recommend a ventilation rate of 8 to 10/min for patients with an advanced airway; however, hyperventilation occurs in most cases. This study was conducted as an attempt to determine the effects of feedback under audio tone guidance on performance of positive-pressure ventilation using a bag-valve device and to apply this technique in clinical practice in order to reduce hyperventilation. METHODS: A total of 36 seniors at our medical school participated in the study. After receiving instruction in performance of positive-pressure ventilation using a bag-valve device, they performed ventilation using a cardiac arrest model with an advanced airway (Test 1). After they took Test 1 without any feedback, they were randomly assigned to the feedback group (Group A) and the control group (Group B) and took Test 2. In Group A, a high-pitched sound was delivered every 7 s for guidance of ventilation. RESULTS: In Group A, ventilation rate approximated feedback rate, whereas, in Group B, it showed a significant decrease, from 8.3+/-2.0 to 7.7+/-2.0/min (p<0.01). The mean ventilation volume did not differ between pre- and post-feedback. The mean inspiration time showed a decrease in both groups. However, no significant difference in mean inspiration time was observed between the two groups. CONCLUSION: Audio tone guidance can control the ventilation rate accurately without any significant change in ventilation volume and inspiration time.

For many years ERCP has been contraindicated in acute pancreatitis. The injection of contrast medium. which may cause hyperamylasemia and occasionally an attack of acute pancreatitis even in normal indivisuals, was allowed only two to three weeks after subsidence of symptoms. Gallstone disease is one of the most common etilogical factors in pancreatitis and migration or impaction of gallstone in the ampulla of Vater causes pancreatitis. (continue...)

The pancreas is formed from dorsal and ventral parts which normally fuse in the second month of intrauterine life. Pancreas divisum occurs when the ventral and dorsal elements fail to fuse; as a result, the main bulk of the pancreas drains through the accessory papilla. It is a congenital variait of pancreatic ductal fusion and drainage anomalies. Since the accessoy papilla and Santorinis duct are too all to accept total pancreatic secretion, obstructive pain and pancreatitis may result. Between March 1983 and February 1988, 631 patients underwent endoscopic retrograde cholangiopancreatography(ERCP) in our hospital. We experiericed one case of pancreas divisum. And then, we report it with brief review of literatures.
