Background: To know the clinical aspects of varicose vein and the effectiveness of operative treatment, the patients who had been operated during the five and a half years were reviewed. Material and Method: From September 1993 to February 1999, 227 patients with varicose vein were operated upon. These patients were reviewed with history taking, physical examination, laboratory tests, operation and follow up visits at an out patient department. Result: The ages of the patients were from 20 to 69 years, mean 40.2 years. varicose veins. Occupations of the patients include housewives, store or factory owners, cooks, waiter or waitresses in a restaurant, salary men(women), teachers, hair stylists, professional athletes, in sequence, most of them require standing all day long. The 126 women had experienced child birth, among them 116 patients delivered more than 2 babies. All patients had protruding leg veins as the symptom. Most of them(61%) had pain. Other additional symptoms were heaviness, heatness, tingling, cramp, fatigue, etc. 68.3% of the patients had the symptoms for more than 10 years. Anatomical location of varicose vein was in long saphenous vein in 157 patients, in small saphenous vein in 27, and in other regions(combined or perforating vein) in 43 patients. There was no operative mortality. There were 2 patients who underwent reoperation due to recurrence during this study period. In one patient, it recurred in the distal perforating vein in small saphenous vein. The other patient had recurrence at the saphenofemoral junction in groin. The patients are doing well after the reoperation, but a long term observation is needed. Conclusion: Clinical aspects of varicose vein were reviewed. For the patients with varicose vein who had saphenofemoral regurgitation, operative treatment seemed to bea safe and effective modality of treatment.

Aims: This study was designed to determine the incidence of altered sensation in patients undergoing orthognathic surgery. Method: Seventy two patients who underwent orthognathic surgery between January, 1999 and December, 1999 constituted the study group. Seven patients were excluded because of lack of follow up. Sixty five patients were followed using objective and subjective neurologic testing during the period immediately following operation, 1 month, 2 months, 6 months, and 1 year postoperatively. Age ranged from 17 to 38 years, with a mean of 24.5 years. Male patients were 21, female 44. Twenty eight bilateral sagittal splitting ramus osteotomy(BSSRO) of mandible were performed, 35 BSSRO with genioplasty, 2 genioplasties. Information on the degree of intraoperative nerve encounter was obtained from the surgical reports in 47 patients and was divided into the following three categories: (1) the nerve was not encountered in 23 patients; (2) the nerve was exposed in 11 patients; (3) the nerve was exposed and repositioned from the proximal segment in 13 patients. Results: Four patients reported altered nerve sensation of lower lip and/or chin(6.2%) at final follow up. Two patients underwent BSSRO and the other two patients BSSRO with genioplasty. Three of the patients underwent nerve exposure during the operation. Conclusion: We suggest that the nerve exposure during the operation might be partly responsible for nerve dysfunction after orthognathic surgery.

The present study was designed to compare the nutritional status of hemodialysis (HD) and continuous ambulatory peritoneal dialysis (CAPD) patients. Subjects were 58 HD patients (male/female = 29/29) and 33 CAPD patients (male/female = 23/10) undergoing dialysis treatment in Artificial Kidney Unit of Chonbuk National University Hospital. For nutritional assessment, %IBW (ideal body weight), %TSF (tricep skin fold), %MAC (mid arm circumference), %MAMC (mid arm muscle circumference), serum albumin, serum transferrin, TLC (total lymphocyte count), SGA (subjective global assessment) and estimated energy and protein intakes by 1-month food frequency method were used. Between HD and CAPD group, mean age (50 $\pm$ 12 vs. 52 $\pm$ 12 yr), dialysis durations (37 $\pm$ 36 vs. 30 $\pm$ 26 mon), dietary energy intakes (28.3 $\pm$ 9.0 vs. 28.8 $\pm$ 8.6 kcal/kg/day), dietary protein intakes (1.1 $\pm$ 0.4 vs. 1.2 $\pm$ 0.3 g/kg/day) and incidence of co-morbid conditions (69.0% vs. 69.7%) were not significantly different. Data by using SGA showed a higher incidence of malnutrition in CAPD patients (45.6%) than in HD patients (36.2%). %IBW (p < 0.001), %TSF (p < 0.001) and %MAC (p < 0.001) were higher in CAPD patients than were in HD patients. But serum albumin (p < 0.001) and transferrin (p < 0.001) were significantly lower in CAPD patients than were in HD patients. A higher incidence of malnutrition was shown in CAPD Patients than in HD Patients due to different dialysis type. A significant finding was that CAPD showed protein deficient malnutrition and HD did calorie deficient malnutrition. It suggests that an adequate dietary intake considering dialysis type prevents a prevalence of malnutrition.

Objective: The goal of this study is to provide the clinical data of patients with brainstem cavernous hemangiomas after treatment with microsurgery or radiosurgery after conducting a retrospective analysis of 21 patients at one institution. Methods: Twenty one patients with brainstem cavernous hemangiomas were treated at the authors' institution between 1995 and 2004 and clinical analysis was performed by retrospective review of medical records and neuroimaging examinations. Thirteen patients underwent microsurgical resection and radiosurgery was performed as an initial treatment in 9 patients. Results: Radical excision was achieved in 12 among 13 patients and transitory neurological deterioration or new neurological deficit developed during the immediate postoperative period in 7 (54%). The final outcomes at 5 - 70 months after surgery were improved in 11 patients (85%) and worsened in 2 patients (15%) compared with the preoperative state. Radiosurgery was performed in 9 patients. During the follow up period from 5 to 70 months there was neurological improvement in 3 patients, no significant change in 3 and deterioration in 3 patients. Two patients developed rebleeding at 5 months, 60 months respectively after radiosurgery. Conclusion: Microsurgery for symptomatic cavernous hemangioma of brainstem can be performed with acceptable morbidity. Fatal complication is rare with careful selection of the optimal operative approach in well selected patients. Radiosurgery is an effective alternative for the lesions which are not accessible by surgical approach, however, there is still a possibility of rebleeding over a long period after radiosurgical treatment and microsurgery should be considered as a treatment with priority for the majority of cases.

Objective : This study was designed to evaluation the diagnostic value of procalcitonin (PCT) in patients with spinal infection, compare to the classical biomarkers such as C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), white blood cell (WBC) count. Methods : All patients who were diagnosed as a spinal infection between January, 2013 and July, 2014 were included in this study. Serum PCT, CRP, ESR, and WBC count were checked at initial hospital visit and once a week serially until they were discharged. Patient's medical history, causes and pathogens of spinal infection were reviewed. Results : Total 34 (16 men, 18 women) patients were included in this study. Mean age of the patients was 65.6 year-old. Causes of spinal infection were pain block procedure (14, 41.2%) and post-operation (5, 14.7%). Out of 25 patients who showed elevated initial serum PCT level, 20 patients (80%) had a combined systemic infection. 14 patients (6.7%) had a sepsis, 3 patients (14.2%) had a urinary tract infection and 2 (9.6%) had a pneumonia. 14 patients (41.2%) showed elevation of serum PCT level during treatment. Among them, 9 patients (64.3%) had a combined infection such as sepsis and urinary tract infection. Conclusion : Serum CRP showed more sensitivity compared to serum PCT in patients with spinal infection. Patients with spinal infection who showed elevated serum PCT level should be investigated for combined infection and proper antibiotics should be applied.

Objective : Vagus nerve stimulation (VNS) has been used in epilepsy patients refractory to standard medical treatments and unsuitable candidates for resective or disconnective surgery. In this study, we investigated the efficacy of VNS to patients who had refractory result to epilepsy surgery and patients with post-traumatic epilepsy. Methods : We analyzed the effect of VNS in 11 patients who had undergone previous epilepsy surgery and patients with intractable post-traumatic epilepsy associated with brain injury. All patients underwent VNS implantation between October 2005 and December 2006. Results : We evaluated seizure frequency before and after implantation of VNS and maximum follow up period was 24 months. In the first 6 months, 11 patients showed an average of 74.3% seizure reduction. After 12 months, 10 patients showed 85.2% seizure reduction. Eighteen months after implantation, 9 patients showed 92.4% seizure reduction and 7 patients showed 97.2% seizure reduction after 24 months. Six patients were seizure-free at this time. Conclusion : We conclude that the VNS is a helpful treatment modality in patients with surgically refractory epilepsy and in patients with post-traumatic epilepsy due to severe brain injury.

Objective : The aim of this study was to determine 30-day mortality and 6-month functional recovery rates in spontaneous intracerebral hemorrhage (S-ICH) patients undergoing hemodialysis treatment for end-stage renal disease (ESRD), and to compare the outcomes of these patients and S-ICH patients without ESRD. Methods : The medical records of 1943 S-ICH patients from January 2000 to December 2011 were retrospectively analyzed with focus on demographic, radiological, and laboratory characteristics. Results : A total of 1558 supratentorial S-ICH patients were included in the present study and 102 (6.5%) were ESRD patients. The 30-day mortality of the S-ICH patients with ESRD was 53.9%, and 29.4% achieved good functional recovery at 6 months post-S-ICH. Multivariate analysis showed that age, Glasgow Coma Scale (GCS) score, pupillary abnormality, ventricular extension of hemorrhage, hemorrhagic volume, hematoma enlargement, anemia, and treatment modality were independently associated with 30-day mortality in S-ICH patients with ESRD (p<0.05), and that GCS score, volume of hemorrhage, conservative treatment, and shorter hemodialysis duration was independently associated with good functional recovery at 6 months post-S-ICH in patients with ESRD (p<0.05). Conclusion : This retrospective study showed worse outcome after S-ICH in patients with ESRD than those without ESRD; 30-day mortality was four times higher and the functional recovery rate was significantly lower in S-ICH patients with ESRD than in S-ICH patients without ESRD.

During 42 month period 91 consecutive patient underwent coronary artery bypass surgery. The mean age of these patient was 57 years [range from 28 to 78 years . There were 57 men and 34 women. The preoperative risk factors that include beyond the 50 % of total patients were male sex, obesity, hypo-high-density lipoproteinemia, smoking, hypercholesterolemia, hyper-low-density lipoproteinemia, hypertriglyceridemia and hypertension. Preoperatively 27 patients had stable angina pectoris and 39 patients of unstable angina pectoris. Twenty five patients had previous myocardial infarction history. The patterns of disease were 8 patients of single vessel involvement, 18 patients of double vessel involvement, 54 patients of triple vessel involvement and 11 patients of left main coronary artery disease. Fifty five patients were in Canadian Cardiovascular Society functional class III. Myocardial revascularization was performed under emergency conditions in 5 patients. Nine percent of patients had previous PTCA history. We performed 16 cases of sequential anastomosis, internal mammary artery harvest in 86 percent of total patients and total 284 distal anastomoses[mean 3.1 anastomosis per patient . The mean ACC time was 60.5 minutes and ECC time was mean 110 minutes. The combined surgeries were 16 cases of endarterectomy, 2 cases of LV aneurysmectomy, 1 case of Bentall operation, 1 case of repair of sinus of Valsalva, 1 case of ligation of coronary AV fistula and 1 case of excision of breast mass. The most common complication was wound infection[12 cases, 13 % . There was one hospital death due to postoperative respiratory failure and low output syndrome in patient with postinfarction VSD, LV aneurysm. Postoperative 88 patients were in Functional class I or II. The 99mTc-MIBI myocardial perfusion scan that used as evaluation of postoperative state was well correlated with patient`s symptoms instead of some disadvantages.

The relative importance of various factors influencing the prognosis and survival in the treatment of thymoma is still controversial. Sixty ave patients operated on for thymoma from Jan. 1981 to Dec. 1994 were evaluated, 28 patients (43.1 %) with myasthenia gravis and 37 patients (56.9%) without. Masaoka staging revealed stage I disease in 28 patie ts(4).1%) , stage ll in 1) patients(20.0%), stage 111 In 22 patients(33.8%), stage IVa in 1 patients(1.5%), and stage IVb in 1 patient(1.5%). There was no operative mortality. A complete resection was performed in 48 patients (73.8%) patients, associated in 10 patients (15.4%) with postoperative adjuvant treatment(radiotherapy 5; chemotherapy 1: radio- and chemotherapy 4). Thymomas were found to be predominantly of the epithelial type in 16 patients(24.6%), predominantly Iymphocytic type in 18 patients(27.7%), and mlxed in 22 patients (33.9%). The overall 5- and 10-year survival rates were 87% and 82%, respectively, Factors indicating a poor prognosis included local invasion, incomplete excision, thymic carcinoma, advanced staging and myasthenia gravis. The de- gree of tumor invasion turned out to be the main prognostic factor, and treatment should be planned ac- cordingly. The prognosis is best predicted by the stage of the tumor as determined intraoperatively and is poorer in patie ts with incomplete resection than in those with complete resection of the thynoma. No recurrence developed In patients with stage I disease.

It has been evident since 1972 that computed tomography(CT) can play an important role in treatment and managment of the cancer patients as four steps; diagnosis, satging Treatment and follow-up. In this paper, we intended to investigate the availability of CT scan and treatment planning computer in 700 cancer patients who have undergone radiation therapy at the division of radiation therapy, Kangnam St. Mary's Hospital, Catholic Medical College between Mar. 1983 and Dec. 1985. The result were as follow; 1. Of 700 irradiated cancer patients, 342 patients ($48.9\%$) were performed CT scan prior to radiation therapy. 2. The distribution of lesions in 342 patients having CT scans was like this; CNS (83 of 104 patients, $79.8\%$), abdomen (44 of 76 patients, $57.9\%$), pelvis (100 of 188 patients, $53.2\%$) etc. in order. 3. The treatment planning computer were used in 280 cancer patients ($40\%$). 4. Of the 280 cancer patients using treatment planning computer, 167 patients ($59.6\%$) applied diagnostic CT scan and remaining 113 patients ($40.4\%$) were made body contour to be used for radiation therapy planning by the treatment planning computer. Authors also made some magnification devices used for small multiformat CT images to magnify into life size, consisting of overhead projector (3M) I.V. stand and mirror. These enabled us to make less errors in tracing the small-sized CT images during input of the anatomical data into the treatment planning computer.
