BACKGROUND: The endothelium is an important regulator of vascular tone via release of relaxing and constricting substances. The regulatory effect of the endothelium has been shown to be impaired in atherosclerotic arteries in human and animal models of hypertension. But there are some debates on extent and developing time of endothelium dysfunction in patients with hypertension, and the determining factors for endothelium dysfunction also were not defined. The objects of this study are to determine whether endothelial function is impaired in coronary and peripheral arteries, and to investigate the predicting factors for endothelial dysfunction in patients with essential hypertension. METHODS: The study patients comprised 14 patients with essential hypertension(M : 7, Mean age : 50+/-2 year) and 6 normal control (M :2, Mean age : 45+/-4 year). We assessed the vasomotor response to acetylcholine and nitroglycerin by change of arterial diameter during the infusion of acetylcholine, from 10(-9M) to 10(-6M) in coronary artery and 7.5, 15, and 25ug/min in left superficial femoral artery, and on intracoronary injection of 200ug nitroglycerin after acetylcholine infusion. RESULTS: 1) There were no significant differences in sex, age, body mass index and ventricular mass index, except systolic(174+/-5 vs 118+/-7mmHg, p<0.001) and distolic blood pressure(106+/-5 vs 75+/-5mmHg,p<0.001) between patients with hypertension and normal control. 2) There were no significant differences in laboratory date of total cholesterol, HDL-cho-lesterol, lipoprotein(a), microaluminuria and von-Willebrand Factor but Fibrinogen level was raised significantly in patients with hypertension than normal control(299+/-26 vs 192+/-23ng/dl, p=0.04). 3) The vasoconstrictor response to acetylcholine, 10-8 to 10-6 M concentration, at proximal, mid, and distal left anterior descending coronary artery were increased significantly in hypertensive patients than normal control(p<0.05). At rest superficial femoral artery, the vasodilator response to acetylcholine, only 25ug/min, was decreased in patients with hypertension(p<0.05). There was no signficant difference in the vasodilator response to nitroglycerin at coronary artery between two groups but in superficial femoral artery, the vasodilator response to nitroglycerin was decreased significantly in hypertensive patients(p<0.05). CONCLUSIONS: The results of this study suggest that endothelium dependent vascular relaxation is impaired in both coronary and superificial femoral artery and it remained to be investigated the predicting factors for endothelial dysfunction in patients with essential hypertension.

BACKGROUND: Periampullary cancer is a relatively common malignancy, and its incidence is increasing. A pancreaticoduodenectomy is the procedure of choice in patients with periampullary cancer. However, leakage of the pancreaticojejunal anastomosis has been a major complication after a pancreaticoduodenectomy, with a frequently reported incidence of 5 percent to 25 percent. The ideal management of the pancreatic stump has not yet been determined. Thus we tried to find a safe and effective pancreatic stump management technique and to monitor the security of the pancreatic stump anastomosis by using the body fluid amylase level. PATIENTS AND METHODS: Forty six (46) consecutive patients who had undergone a pancreaticoduodenectomy, between January 1990 and January 1998, were evaluated retrospectively. Before June 1997, we did 36 pancreaticojejunostomies without long stent insertion into the pancreatic duct (group 2). After that, we did 10 P-Jstomies with long stent insertion (group 1). A long silicone stent was used for intubation of the anastomosis. Also the amount of pancreatic juice drainage from the long pancreatic duct tube was checked daily. We placed two Penrose drains and one Jackson-Pratt drain near the anastomosis. Patients were monitored for clinical evidence of a pancreatic fistula by evaluation of the amylase concentration in serum and the peritoneal drainage at postoperative day 7. The normal range of body fluid amylase was defined to be within five times of the normal serum amylase level. Cholangiography, which was obtained through a T-tube or a percutaneous transhepatic catheter, was performed on postoperative day 7 and was used to assess to leakage from or the obstruction at any of the three reconstructive anastomoses. RESULTS: In group 1, there was no leakage from the P-Jstomy site. The daily mean pancreatic juice amount and body fluid amylase level were 76.6 ml/day (range, 0.4-137.4 ml/day) and 147.4 U/L (range,44-323 U/L). In group 2, there were 4 cases of leakage at the P-Jstomy site (11.1%). CONCLUSION: An external long pancreatic duct stent insertion is an effective and safe method for management of a pancreatic remnant. We could check the amount of the daily pancreatic juice precisely. Effective decompression of the P-Jstomy was achieved by long stent insertion. We could monitor the security of the pancreatic stump anastomosis by the body fluid amylase level. We suggest that our method, which monitors the body fluid amylase level, is effective in early detection and treatment of P-Jstomy site leakage. The effort to find the best method for management of the pancreatic remnant should be continued.

STUDY DESIGN: A retrospective follow-up study comparing soft disc cervical myelopathy (Group A) and spondylotic bar cervical myelopathy (Group B). OBJECTIVES: To analyze different factors by comparing preoperative radiological and clinical data of Group A with that of Group B. SUMMARY AND LITERATURE REVIEW: The different causes of cervcal myelopathy resulted in different symptoms and prognoses. MATERIALS AND METHOD: A clinical and radiological analysis of the data in 31 patients who underwent an anterior cervical decompression and fusion was performed to assess the different factors between two groups. The patients were classified into two groups; 20 in Group A and 11 in Group B. Comparisons between the two groups were made in regard to the physical findings, radiological and clinical evaluation. RESULTS: The duration of myelopathy was 3 months in Group A and 8.7months in Group B. Of all cases, 5 cases (25.0%) in group A and 4 cases (36.4%) in group B had myelopathy associated with radiculopathy. Of the 20 cases in group A with myelopathy, 7 cases had a median compression and 13 cases had a paramedian compression on MRI. Of the 11 cases in group B with meylopathy, 9 cases had a median compression and 2 cases had a paramedian compression on MRI. The follow-up MRI of the 14 cases (73.7%) in group A and 2 cases (20.0%) in group B showed spontaneous regression of the T2 WI high signal intensity. CONCLUSION: In degenerative disc disease, the different causes of cervcal myelopathy result in different symptoms and prognoses. However, the treatment of choice in both groups is a one level anterior decompression and fusion.

BACKGROUND: Periampullary cancer is a relatively common malignancy, and its incidence is increasing. Prognosis in these patients depends upon resection of the tumor because surgery is the only effective treatment for irradicating the disease. There has, therefore, been a renewed interest in the role of serological markers early diagnostic tools for periampullary cancer. The potential role of serological markers is not limited only to early detection, but may also be of assistance in the difficult clinical dilemma of differentiating periampullary cancer from other diseases. Furthermore, serological markers of periampullary cancer might be used in follow-up patients after treatment, particularly after surgical resection, in order to select those with minimal disease likely to respond better to adjuvant treatment and/or radiotherapy. METHODS: From March 1989 to May 1997, 54 patients were admitted to Sanggye Paik Hospital, InJe University, and had pathologically confirmed periampullary cancer. Of those, 28 patients underwent a biliary bypass or a drainage procedure [Group I], and the others received resection procedures (Whipple's operation or pylorus-preserving pancreatoduodenectomy)[Group II]. Preoperative and postoperative serum levels of bilirubin, carcinoembryonic antigen (CEA), and carbohydrate antigen 19-9(CA19-9) were measured in all patients. We evaluated the relation of the postoperative increase or decrease in those tumor markers to survival, and we discuss the usefulness of those markers as prognostic indicators in periampullary cancer. In this study, we focused on the changes in the CEA and the CA19-9 levels as function of the serum bilirubin concentration change. RESULTS: The bilirubin, CEA, and CA19-9 concentrations decreased significantly in Groups I and II after operation. The correlation between the decreases of the bilirubin and the CEA levels was statistically significant, but that between the bilirubin and CA19-9 had no statistical significance, in spite of the fact that the preoperative and the postoperative tumor marker concentrations had changed markedly. The reason for the statistical insignificance of the CA19-9 result may be the its relatively small sample size and the wide standard variation. The overall median and mean survival time of Group I were 4 months and 11 months, respectively, and those of Group II were 17 months and 21 months. CONCLUSION: We found that the serum the CEA and the CA19-9 levels could be used as a useful prognostic indicator change according to the serum bilirubin concentration even after a biliary drainage procedure and a biliary bypass. We conclude that various biliary bypass and drainage procedures can be effective treatments in periampullary cancer. However, because it is thought that many tumor markers are greatly affected by hyperbilirubinemia, liver dysfunction or cholestasis, further studies of the exact mechanism for the decrease or the increase in the tumor marker level as a function of the serum bilirubin concentration are mandatory. Precise information obtained by using multivariate analysis of large samples is essential for more accurate evaluation.

OBJECTIVE: Rheumatoid arthritis (RA) is a systemic disease that can affect the cervical spine, especially the atlantoaxial region. The present study evaluated the risk factors for atlantoaxial subluxation (AAS) development and progression in patients who have undergone surgical treatment. METHODS: We retrospectively analyzed the data of 62 patients with RA and surgically treated AAS between 2002 and 2015. Additionally, we identified 62 patients as controls using propensity score matching of sex and age among 12667 RA patients from a rheumatology registry between 2007 and 2015. We extracted patient data, including sex, age at diagnosis, age at surgery, disease duration, radiographic hand joint changes, and history of methotrexate use, and laboratory data, including presence of rheumatoid factor and the C-reactive protein (CRP) level. RESULTS: The mean patient age at diagnosis was 38.0 years. The mean time interval between RA diagnosis and AAS surgery was 13.6±7.0 years. The risk factors for surgically treated AAS development were the serum CRP level (p=0.005) and radiographic hand joint erosion (p=0.009). The risk factors for AAS progression were a short time interval between RA diagnosis and radiographic hand joint erosion (p<0.001) and young age at RA diagnosis (p=0.04). CONCLUSION: The CRP level at RA diagnosis and a short time interval between RA diagnosis and radiographic hand joint erosion might be risk factors for surgically treated AAS development in RA patients. Additionally, a short time interval between RA diagnosis and radiographic hand joint erosion and young age at RA diagnosis might be risk factors for AAS progression.

OBJECTIVE: To evaluate the effects of the reactive oxygen species (ROS) generated with a xanthine(X) and xanthine oxidase (XO) system on sperm function, the change of sperm characteristics, lipid peroxidation, and DNA fragmentation in bovine spermatozoa. MATERIALS AND METHODS: ROS were produced using a combination of 100 micrometer X and 50 mU/ml XO. The ROS scavengers: superoxide dismutase (SOD)(200mu/ml) and catalase (500mu/ml) were also tested. Spermatozoa were incubated for 2 hours in BWW medium with a combination of X-XO supplemented with or without ROS scavengers at 37degrees C under 5% CO2 incubator. Sperm movement characteristics by CASA (computer-aided sperm analysis), HOST (hypoosmotic swelling test), Ca-ionophore induced acrosome reaction, malondialdehyde formation for the analysis of lipid peroxidation, the percentage of DNA fragmentation using the method of TdT-mediated nick end labelling (TUNEL) by flow cytometry were determined after 2 hours incubation. RESULTS: The action of ROS on bovine spermatozoa resulted in a decreased in capacity for sperm motility, Ca-ionophore induced acrosome reaction and membrane integrity, an increased in malondialdehyde formation and the percentage of sperm with DNA fragmentation. In the effects of antioxidant, catalase completely alleviated the toxic effects induced by the ROS in terms of sperm function and characteristics, however SOD exhibited no capacity to reduce the toxic effects. CONCLUSION: The ROS can induce significant damages to sperm functions and characteristics. The useful ROS scavengers can minimized the defects of sperm function and various damages of spermatozoa.

PURPOSE: To evaluate the effectiveness of percutaneous catheter drainage in treatment of the lung abscess. MATERIALS AND METHODS: We treated the lung abscesses in 14 patients(12 men, 2 women), who did not respond to medical therapy, by percutaneous catheter drainage under fiuoroscopic or ultrasound guidance. One abscess due to infacted bulla was managed by combination treatment with alcohol sclerosing therapy. Patients were followed by serial chest radiographs every three days and the amount of drained or aspirated pus evaluated. The treatment effect and recurrence were followed by chest PA and lateral chest at one week after removal of drainage catheter. RESULTS: Thirteen patients(93%) recovered clinically and radiologically within 3 days. In 10 patients, drainage catheter could be removed within 2 weeks, and three patients, the catheter was keept longer. Most complications were mild ;vague to moderate chest pain(n=14), mild hemoptysis(n=2), and pneumothorax(n=I). One man who suffered from far advanced pulmonary tuberculosis died of asphyxia caused by massive hemoptysis 16 days after percutaneous drainage. CONCLUSION: Percutaneous catheter drainage is a safe and effective method for treating lung abscess.

OBJECTIVE: The purpose of this study is to evaluate the associations between 30-day mortality and various radiological and clinical factors in patients with traumatic acute subdural hematoma (SDH). During the 11-year study period, young patients who underwent surgery for SDH were followed for 30 days. Patients who died due to other medical comorbidities or other organ problems were not included in the study population. METHODS: From January 1, 2004 to December 31, 2014, 318 consecutive surgically-treated traumatic acute SDH patients were registered for the study. The Kaplan–Meier method was used to analyze 30-day survival rates. We also estimated the hazard ratios of various variables in order to identify the independent predictors of 30-day mortality. RESULTS: We observed a negative correlation between 30-day mortality and Glasgow coma scale score (per 1-point score increase) (hazard ratio [HR], 0.60; 95% confidence interval [CI], 0.52–0.70; p<0.001). In addition, use of antithrombotics (HR, 2.34; 95% CI, 1.27–4.33; p=0.008), history of diabetes mellitus (HR, 2.28; 95% CI, 1.20–4.32; p=0.015), and accompanying traumatic subarachnoid hemorrhage (hazard ratio, 2.13; 95% CI, 1.27–3.58; p=0.005) were positively associated with 30-day mortality. CONCLUSION: We found significant associations between short-term mortality after surgery for traumatic acute SDH and lower Glasgow Coma Scale scores, use of antithrombotics, history of diabetes mellitus, and accompanying traumatic subarachnoid hemorrhage at admission. We expect these findings to be helpful for selecting patients for surgical treatment of traumatic acute SDH, and for making accurate prognoses.
