We have reviewed ovarian mature cystic teratomas with features of chronic thyroiditis that were diagnosed at the department of pathology, Seoul National University Hospital during 7 years, 1984-1991. Twenty three case(8%) containing thyroid tissue among 285 ovarian mature teratomas were available for histopathologic examination. Among these, 4 cases(1.4%) showed lymphocytic infiltration with lymphoid follicle formation. These four cases were examined according to the strict histologic criteria of autoimmune thyroiditis and reactive non-autoimmune thyroiditis for the purpose of differentiation of pathogenesis. Two cases were similar to autoimmune in nature and the other two cases simply seemed to reflect reactive features to adjacent stimulating elements. In conclusion, thyroid tissue present in ovarian cystic teratoma may have histologic features of chronic thyroiditis of either autoimmune or non-autoimmune origin.

Spinal arachnoid cysts are a rare disease with an unknown origin. Because of their broad base, a total laminectomy with or without fusion has been the treatment of the choice. We encountered 5 patients with a spinal arachnoid cyst who were treated by recapping laminoplasty after pars osteotomy. This procedure has not been reported in Korea. All patients showed neurological recovery with no recurrence of the cyst. The findings on the stressed plain film confirmed bony union and stability of the posterior element.

OBJECTIVE: To determine the effects of abdominal functional electrical stimulation(FES) on the ability to clear the broncheal secretion in high spinal cord injury(SCI) patients. METHOD: Eleven cervical SCI male patients were assessed for the pulmonary function using a routine pulmonary function test. Maximal expiratory pressure(MEP) and peak expiratory flow rate(PEFR) measurements were recorded during (1) spontaneous cough attempts and (2) cough attempts with FES applied to the abdominal wall. Each measurement was recorded in supine and sitting positions. The portable FES unit was set at 24 Hz, with a pulse width of 150 microsecond( s), an asymmetrical biphasic waveform and a maximal intensity to 90 mA. RESULTS: All subjects had a decreased vital capacity, peak expiratory flow and increased ratio of forced expiratory volume at one second(FEV1) to the forced vital capacity(FVC) in a routine pulmonary function test. These cervical SCI patients were greatly reduced the MEP and the PEFR when they coughed spontaneously. FES-assisted coughing increased the MEP and PEFR in all patients in a supine and sitting positions with statistical significance(p<0.05). CONCLUSION: By increasing the MEP and PEFR, abdominal FES could enhance the coughs in high SCI patients. Abdominal FES can be a useful physical therapy for the prevention and treatment of pulmonary complications in high SCI patients at the bed side as well as at homes.

OBJECTIVE: Large loop excision of transformation zone(LLETZ) is gaining popularity as an alternative to other ablative or cone methods for the treatment of cervical intraepithelial neoplasia(CIN). The optimal management of CIN after LLETZ, however, remains controversial and the reliable predictors of residual disease after LLETZ have not been consistently identified. This study was performed to identify factors to predict residual disease after LLETZ. METHODS: From August 1993 to July 1995, 133 patients who received subsequent hysterectomy after LLETZ in Department of Obstetrics and Gynecology at Seoul National University Hospital were retrospectively reviewed. Residual disease was defined as positive findings of CIN or further advanced findings in hysterectomy specimen. The age of patients, the severity of disease and the status of resection margin(RM) were analyzed for predictive values of residual disease. The Chi-square test, Fisher's exact test and Student t-test were used for statistical analysis. RESULTS: The residual disease after hysterectomy was negative in 85.7%(114/133) and positive in 14.3%(19/133). Among 19 cases with positive residual disease, 3 cases were revealed to be microinvasive cervical cancer. The mean age of patients with no residual disease was 42.5 years(range; 27-71) and that of patients with residual disease was 49.1 years(range; 33-72). Nine out of 94 cases(9.6%) with negative RM and 10 out of 39 cases(25.6%) with positive RM in LLETZ had residual disease. Two out of 14 cases(14.3%) with CIN II and 17 out of 119 cases(14.3%) with CIN III in LLETZ had residual disease. The success of LLETZ which means no residual disease was influenced by the age of patients(p=0.005) and the status of resection margin of LLETZ(p=0.032). CONCLUSION: The negative resection margin in LLETZ does not always guarantee that there is no residual disease. Close preoperative workup and more aggressive treatment plan(wide conization or hysterectomy) should be considered in patients who has higher possibility of positive residual disease such as old age and positive resection margin in LLETZ.

This study was conducted to identify the factors for serum cholesterol level among Korean Air Force pilots. We obtained risk factors for 408 pilots examined during period from January 1996 through March 1997. The associations between total cholesterol, LDL-cholesterol, triglyceride, HDL-cholesterol and age, body mass Index(BMI), smoking, drinking, blood pressure, flight time and fat intake were analyzed. The mean serum total cholesterol, HDL-cholesterol, LDL-cholesterol, and triglyceride levels were 161.8+/-31.0 mg/dl, 475+/-11.0 mg/dl, 93.1+/-30.2 mg/dl, and 106.5+/-61.3 mg/dl respectively. Possible risk factors were total flight time, BMI, smoking, drinking, exercise, flight, and fighter or not. Total flight time and BMI were statistically significant factors In serum cholesterol level while controlling for the effect of the remaining factors. The longer the total flight time, the higher the level of serum total cholesterol. Total flight time, BMI, and drinking amount were statistically significant factors in serum HDL-cholesterol while controlling for the effect of the remaining factors. The higher the BIM, the lower the level of HDL-cholesterol. BMI was a statistically significant factor in seurm LDL-cholesterol while controlling for the effect of remaining factors. Total flight time, BIM, and flight were statistically significant factors in serum triglyceride while controlling for the effect of the remaining factors. Conclusively, BIM was a only significant factor in all four lipid levels, and total flight time took an affect to total cholesterol, HDL-cholesterol, and triglyceride levels.

BACKGROUND: Distal humerus intercondylar fractures are intra-articular and comminuted fractures involving soft tissue injury. As distal humerus is triangle-shaped, parallel plating coupled with articular fixation would be suitable for bicolumn restoration in treatment of distal humerus intercondylar fracture. METHODS: This study included 38 patients (15 males and 23 females) who underwent olecranon osteotomy, open reduction and internal fixation with the triangle-shaped cannulated screw and parallel locking plates (triangular fixation technique). Functional results were assessed with the visual analog scale (VAS) scores, Mayo elbow performance (MEP) scores and Disabilities of the Arm, Shoulder and Hand (DASH) questionnaires. Anteroposterior and lateral elbow radiographs were assessed for reduction, alignment, fracture union, posttraumatic arthrosis, and heterotopic ossification, and computed tomography (CT) scans were used to obtain more accurate measurements of articular discrepancy. RESULTS: All fractures healed primarily with no loss of reduction. The mean VAS, MEP, and DASH scores of the affected elbow were not significantly different from those of the unaffected elbow (p = 0.140, p = 0.090, and p = 0.262, respectively). The mean degree of flexion was significantly lower in the affected elbow than in the unaffected elbow, but was still considered as functional (p = 0.001, > 100degrees in 33 of 38 patients). Two cases of articular step-offs (> 2 mm) were seen on follow-up CT scans, but not significantly higher in the affected elbow than in the unaffected elbow (p = 0.657). Binary logistic regression analysis revealed that only Association for Osteosynthesis (AO) type C3 fractures correlated with good/excellent functional outcome (p = 0.012). Complications occurred in 12 of the 38 patients, and the overall reoperation rate for complications was 10.5% (4 of 38 patients). CONCLUSIONS: Triangular fixation technique for bicolumn restoration was an effective and reliable method in treatment of distal humerus intercondylar fracture. This technique maintained articular congruency and restored both medial and lateral columns, resulting in good elbow function.

OBJECTIVE: The purpose of this study was to determine whether quantitative sensory test can be used as a screening test of peripheral polyneuropathy in patients with diabetes mellitus, and to evaluate the severity of peripheral polyneuropathy in patients with diabetes mellitus using quantitative sensory test. METHOD: We performed nerve conduction study to right upper and left lower extremity of the patients. Quantitative sensory test was performed using TSA-2001 thermal sensory analyser on right thenar and left foot dorsum in both diabetic and control groups. RESULTS: 1) The warm sense and heat pain threshold were higher, the cold sense and cold pain threshold were lower in diabetic group than age-matched control group (p<0.05). 2) The warm sense and heat pain threshold were higher, the cold sense and cold pain threshold were lower in diabetic group than young-aged control group (p<0.05). 3) As nerve conduction study results were severe, the cold sense threshold in right thenar were decreased (p<0.05). CONCLUSION: Quantitative sensory study in patients with diabetes mellitus are sensitive to identify neuropathic change; thus, they would be used as the screening method of diabetic peripheral polyneuropathy.

BACKGROUND: The prevalence of obesity is increasing year after year in Korean; and gastroesophageal reflux disease(GERD) is increasing in this population as well. The aim of this study is to assess the association between age, body mass index(BMI) and GERD in healthy Korean adults. METHODS: Analysis was done on 1,016 subjects who had not had malignancy, uncontrolled metabolic disease, enteric surgery and organic esophageal disease. They completed a questionnaire that included past history and reflux symptoms. Endoscopy was performed by two gastroenterologists who were not given any patient information. Existence of GERD was determined by the esophageal syndrome criteria of the Montreal guidelines. Subjects were categorized by BMI, initially as: underweight, normal(18.5< or =BMI<25), overweight(25< or =BMI<30) and obese by the WHO criteria, and then as: underweight, normal(18.5< or =BMI<23), overweight(23< or =BMI<25) and obese by the Asian-Pacific criteria. RESULTS: The overall[is this correct] prevalence of GERD in our subjects was 15.5%. Age and sex were not correlated factors for GERD. By the WHO and the Asian-Pacific criteria, GERD was present in underweight(10.0%, 12.1%), normal(13.9%, 14.4%), overweight(18.6%, 13.0%) and obese groups(21.0%, 18.8%). No meaningful association was seen between BMI and GERD in either of the classified groups. Erosive GERD was seen in 83 subjects (8.2%) on endoscopy. The obese(BMI> or =25) group(12.1%) showed a meaningful increment in the prevalence of erosive GERD compared to the non-obese(BMI<25) group(6.2%)(p value 0.002). CONCLUSION: The prevalence of GERD in healthy Korean adult subjects was not closely associated with obesity and age[according to BMI]; however, erosive GERD was found to have a strong association with obesity.
