Legg-Calve-Perthes disease (LCP) has been reported to be associated with hypofibrinolysis and a deficiency in coagulation. The goal of this prospective study was to confirm or refute these findings and to establish a guide for a screening test. The coagulation systems of twenty-three patients with Legg-Calve-Perthes disease were evaluated by means of the tests which included prothrombin time, activated partial thromboplastin time, antithrombin-III (AT-III), protein C, protein S, lipoprotein(a), and anticardiolipin antibody (ACA). Study subjects were 21 males and 2 females. Mean age was 8.7 years. No abnormal results were found for Antithrombin-III and Protein S, but 2 patients had low Protein C level. Two of 23 patients had Lipoprotein(a) values greater than 30 mg/dl. Another two patients had positive finding for Anticardiolipin antibody. There were no statistical differences in all parameters between Catterall group stage in the patients with Legg-Calve-Perthes disease. We were unable to establish an association between thrombotic tendency and Legg-Calve-Perthes disease based on this prospective study. So, routine screening of patients with Legg-Calve-Perthes disease for abnormalities of antithrombotic factors would be not warranted.

Omental pregnancy is an extremely rare form of abdominal pregnancy that may cause life threatening massive hemorrhage in case of rupture. It may occur by primary implantation of the fertilized ovum in the omentum. The diagnosis is very difficult, but prompt surgical intervention is required when it is suspected, because perinatal mortality and maternal mortality in abdominal pregnancy were 85~95% and 0.5~6%. We experienced a case of omental pregnancy in the first times and reported it with brief review of literature.

PURPOSE: In most patients of Kawasaki disease(KD), fever subsides within 48 hours after infusion of intravenous immunoglobulin(IVIG), but in some cases, retreatment of IVIG is needed because of prolonged fever. This study was performed to findout the factors associated with the retreatment of IVIG in KD. METHODS: Patients with KD, treated with IVIG were classified into two groups : single IVIG treatment group(defeverescence within 48 hours after starting IVIG : group B) and IVIG retreatment group(retreatment with IVIG for fever over 48 hours despite the 1st infusion of IVIG; group A). We compared the clinical symptoms, laboratory findings, clinical signs and echocardiogram findings between group A and B. RESULTS: The mean CRP level of group A was higher than that of group B(P= 0.001), and the mean cholesterol level of group A was lower than that of group B(P=0.002). In CRP level is above 10 mg/dL, odds ratio for retreatment of IVIG is higher than that of level below 10 mg/dL. As cholesterol level decreased, the odds ratio for retreatment with IVIG increased. CONCLUSION: When readministration of IVIG in KD patients for prolonged fever over 48 hours, the consideration of the initial levels of relatively low serum cholesterol and high CRP is recommended.

PURPOSE: To evaluate the merits of this technique and to provide a standard for comparison with futuretreatment alternatives. MATERIALS AND METHODS: We retrospectively reviewed the records of 52 patients withdirect CCF treated at the Yonsei Medical Center between 1983 and 1997 by transarterial or transvenous embolizationusing detachable balloon(s) and/or coils. RESULTS: Among the 52 cases, 51 were traumatic in origin, while onlyone was the result of a ruptured aneurysm. The three most common presentations were chemosis, bruit, andpulsatile proptosis. Forty-five patients were successfully treated with detachable balloon(s) and/or coils andinternal carotid blood flow was preserved in 35. When coils were used (1993-7), the ICA preservation rate washigher than when they were not used (1983-92). To confirm statistical significance, however, more studies areneeded. Four patients who initially presented with incomplete occlusion showed spontaneous occlusion on follow upangiography. In two patients, surgical ligation was performed because embolization failed and there was incompleteocclusion of the fistula. We experienced complications such as transient 3rd and 6th cranial nerve palsy,migration of deflated balloons and coils to the lung, and loss of vision. CONCLUSION: Transarterial andtransvenous embolization with detachable balloon(s) and/or coils provides a high rate of fistula obliteration withlow morbidity. In particular, the use of coils led to an increased rate of ICA preservation, thus and isconsidered as a good treatment modality for CCF obliteration.

BACKGROUND: Systemic hypertension produces varying degree of LVH which is associated with increased cardiovascular morbidiity. Previous studies have documented regression of LVH with various antihypertensives including calcium channel blockers, except diuretics and vasodilators. Recently echocadiographic assessment of the change of left ventricular mass(LVM) after antihyertensive therapy have been reported to offer prognostic cardiovascular information. The aim of this echocardiographic study is determining the influence of nicardipine, a calcium channel blocker, on the change of LVM in patients with essential hypertenison. METHODS: Left ventricular mass(LVM) and left ventricular mass index(LVMI) were measured by M-mode echocardiography in 15 patients with essential hypertension. Nicardipine, a calcium channel blocker, was administered for 6 months and two echocardiographies were done before and after administering, respectively. RESULTS: In the 15 patients treated for 6 months, systolic and diastolic pressure remained very significantly decreased compared with pressure before before therapy(135+/-15mmHg vs 168+/-26mmHg, and 86+/-7mmHg vs 105+/-16mmHg, both p<0.01). Concomitantly both LVM and LVMI decreased significantly(209+/-49g vs 235+/-71g, and 116+/-6g/m2 vs 131+/-38g/m2,both p<0.05). And no change was noted in left ventricular cavity size, demonstration that LVM reduction was due to regression of hypertrophy. CONCLUSION: This study showed that nicardipine produced a significant decrease in blood pressure, LVM, and LVMI over the 6 months period. And large and longterm controlled studies are needed for the clarification of the association between nicardipine and regression of LVH in hypertensive patients.

PURPOSE: Surgeons are confronted frequently with the diagnostic and therapeutic challenges in the cases of acute appendicitis in the elderly. Despite the improvements in management, the morbidity and mortality remain high. In order to verify contributing factors of high morbidity and mortality and establish more proper diagnostic and therapeutic strategies, we compared the clinical characteristics and outcomes of acute appendicitis in the elderly with those of younger people. METHODS: We retrospectively reviewed medical records of 30 elderly and 248 younger people who were pathologically diagnosed as appendicitis after an appendectomy. RESULTS: There was no difference in the rates of occurrence of right lower abdominal pain and tenderness between the two people. The rate of appendiceal perforation was significantly higher in the elderly. Prehospital delay was significantly longer in the elderly. Concomitant diseases were more prevalent in the elderly. The hospital stay was significantly longer and the rate of complication was relatively higher in the elderly also. CONCLUSIONS: When a vague and unexplained abdominal discomfort occurs in the elderly, we should suspect and rule out acute appendicitis as the cause of the discomfort. Early aggressive diagnostic and therapeutic interventions are essential components in managing acute appendicitis in the elderly. In addition, perioperative evaluation and prophylactic measures for concomitant diseases are needed to decrease morbidity and mortality in the elderly.

PURPOSE: Multiple rib fracture (MRF) and a hemopneumothorax accompany with most blunt chest traumas. We aimed to analyze the factors increasing the probability of a hemopneumothorax. In addition, other injuries accompanying MRF were analyzed. METHODS: We retrospectively reviewed the medical records of 154 mutiple rib fracture patients who visited our hospital between January 2005 and December 2007. The medical records were reviewed for sex, age, mechanism of injury, location, number of fractures, distance of dislocated rib fragments, and presence of complications. We measured the distance of bony dislocations by using the PACS (Picture Archiving and Communication System). RESULTS: The average number of rib fractures was 3.7+/-2.1, and the number of rib fractures significantly influenced the incidence of a hemothorax (p<0.001). The risk of a phemothorax was increased in a bilateral MRF compared to a unilateral MRF (p=0.027). The distance of dislocated rib fragments influenced the probability of a hemothorax significantly (p=0.018), and subcutaneous emphysema and lung contusion were significantly associated with a pneumothorax (p=0.021, p=0.036). CONCLUSION: The number of MRFs did not influence the risk for a pneumothorax, but did influence the risk for a hemothorax. The laterality, distance of dislocation, also had an influence on the risk for a hemothorax. Also, subcutaneous emphysema and lung contusion were increased in cases with a pneumothorax. We must consider the possibility of a hemothorax even when the initial chest X-ray shows no evidence of a hemothorax. If a lung contusion is present, then an occult pneumothorax must be considered.

Hypoxia is a serious aviation problem and can always be a source of dangerous aerospace accidents. Hypoxic chamber flight training used to evaluate hypoxia tolerance via TUC (time of useful consciousness) and to become aware of hypoxic symptoms. Because TUC depends on subjective symptoms and lacks strict objectivity, pulse oximetry monitoring has become useful in the aviation environment. In this study, we monitored arterial oxygen saturation (SaO2) by pulse oximetry in the ROKAF subjects (n=33) experiencing hypoxia at the simulated altitude of 25,000 ft. The duration from mask-off to mask-on (TUC), the duration from mask-off to the time of SaO2 of 90% (T90), the duration from 90% to 70% of SaO2(T70), and the SaO2 value at mask-on (bottom SaO2) were examined. The mean bottom SaO2 and TUC were 64.5% and 180 sec, respectively. The subjective hypoxic symptoms were facial flushing, thinking impairment, dyspnea, sweating, anxiety, and so on, in descending order. The majority of the subjects put on their mask before 70% of SaO2 was reached or before they felt any severe symptoms. In comparison with the data of JASDF (Yoneda, 2000), TUC, T90, and T70 were longer in JASDF, but bottom SaO2 and pulse increasing rate during hypoxia (PR/TUC) were higher in ROKAF. Also, TUC in the subjects of this study was much shorter than those of 10 years ago. These may be due to different training protocols, but not enough data exists to explain such difference. The need for the reconsideration of the hypoxic training from the various viewpoints is raised.

Gastric carcinoid tumors were previously believed to be rare lesions, representing less than 2% of all carcinoid tumors and less than 1% of all stomach neoplasms. More recent studies have demonstrated that they may constitute as much as l0-30% of carcinoid tumors. We recently experienced a 35-years old businessman with gastric carcinoid tumor who camplained of postprandial epigastric discomfort. Gastrofiberscope showed protruding mass with central depression and erasion which was located on greater curvature of lower body and its size was 1 x 1 cm. Gastroendoscopic biopsy was per formed. It was identified to carcinoid tumor(Argyrophilic tumor). EUS(endoscopic ultrasonography) revealed that the lesion was limited to submucosa without evidence of any metastasis to adjacent lymph node. The carcinoid tumor was successfully removed by endoscopic polypectomy. Gastrofiberscope and EUS 9months after polypectomy showed that the lesion was nearly normal mucosa without submucosal thickening.
