BACKGROUND: As indicators of obesity, waist circumference (WC), body mass index (BMI), and adiponectin are well known risk factor for diabetes mellitus. The objectives of this study were to measure the independent association between these obesity indicators and diabetes and to examine the combined effect of these indicators on diabetes in a Korean population. METHODS: The WC, BMI, and serum adiponectin were measured in 6,505 healthy Koreans and were classified into tertile groups for men and women. The independent and combined associations of the obesity indicators with diabetes were measured using logistic regression analyses. Diabetes was defined as fasting serum glucose greater than 126 mg/dL or taking medication. RESULTS: Levels of adiponectin were inversely associated with BMI and WC and directly associated with age and high density lipoprotein cholesterol (HDL) cholesterol (P <0.001). After adjusting for age, WC, and other lifestyle factors, low levels of adiponectin were associated with an increased prevalence of diabetes. Further adjustment for HDL cholesterol and triglyceride attenuated this association in both men and women. The best cut-off value of adiponectin in terms of identifying the presence of diabetes was 5.5 /ml with a sensitivity and specificity of 46.7% and 63.9% for men and 9.5 /ml with a sensitivity and specificity of 68.2% and 55.2 for women. CONCLUSIONS: These results suggest that adiponectin was associated with diabetes. The association was independent of WC and was partly modified by HDL and triglyceride. There were no effect modifications of adiponectin with WC on diabetes.

PURPOSE: This study was performed to examine if CT classification of renal blunt injury could aid in expectation of hemodynamic stability and clinical decision of whether to intervene surgically. MATERIALS AND METHODS: Over a 80-month period between July 1987 and March 1994, 41 patients were admitted to our hospital with the diagnosis of renal blunt injury. The renal blunt injuries were classified on Fedede's three-point scale CT classification methods :grade I, contusion, intrarenal hematoma, segmental infarction, and small subcapsular hematoma;grade II, complete or incomplete laceration, large subcapsular hematoma, and renal fracture;grade Ill, shattered kidney and renal pedicle injury. Hemodynamic stability, treatment method and clinical outcome of the patients with different CT grade were analyzed retrospectively. RESULTS: All 34 patients with grade I or II CT findings were hemodynamically stable and were successfully managed with conservative method. Among 7 patients with grade III CT findings, 6 patients were hemodynamically unstable. Out of the 6, One patient with grade IIIb or renal pedicle injury was expired before surgical intervention due to ischemic shock. Four patients were intervened surgically with one failure to thrive. The remaining one patient refused to be intervened surgically, and was discharged against medical advice. Only one out of 7 patients was hemodynamically stable and was managed conservatively. CONCLUSION: The patients with grade I or II CT findings are prone to be hemodynamically stable and to be managed with conservative method. But the patients with grade III CT findings are more likely to be hemodynamically unstable. Therefore patients with grade III CT findings should be closely monitored and be pre- pared for the possibility of immediate surgical intervention

BACKGROUND: High-frequency jet ventilaion is considered a reliable technique for anesthesia and critical care including respiratory failure but there are adverse reactions such as carbon dioxide retension and dry of respiratory mucosa. The purpose of this study was to confirm the effects of combined high- frequency jet ventilation (HFJV) and converntional mechanical ventilation (CMV) on the cardiovascular system, arterial blood gases tension and mean airway pressure in 9 Korea mongrel dogs with pulmonary edema induced by oleic acid. METHODS: During CMV with 20 breaths/minute, 10 ml/kg of tidal volume and F1O2 1.0, parameers were evaluated (base line value). When pulmonary edema was developed, HFJV was applied initially with 120 breaths/minute, inspiratory time 30% and driving pressure 40 psi F1O2 1.0 for 60 minutes (control value) and thereafter simultaneous use of CMV was applied with the tidal volume of 10 ml/kg and each respiratory rate 8, 4, 2, 1, 0.5 per minute for 30 minutes. RESULTS: Combined application of HFJV and CMV (above repiratory rate 1 per minute) achieved the improvement of oxygenation and carbon dioxide elimination, and Paw was decreased without undesirable effects on cardiovascular system in case of the induced pulmonary edema. CONCUSIONS: From above results we recommanded that HFJV combined with CMV may be a useful method of treatment for respiratory failure.

PURPOSE: To evaluate the patterns of hemodynamic changes caused by various pathologic liver conditions. MATERIALS & METHODS: Combined CT hepatic arteriography(CTHA) and CT arterial portography(CTAP), performed in 185 consecutive patients, including 150 with hepatocellular carcinoma, were retrospectively analysed. Of these patients, 48 showed various patterns of hemodynamic change. such change caused by occlusion, stenosis and/or cavernous transformation of the portal vein, by occlusion or stenosis of the hepatic artery, or by the presence of arterioportal(AP) shunt could be classified as follows : type 1, decreased or absent portal flow ; type 2,decreased or absent hepatic arterial flow ; type 3, AP shunt without portal tumor thrombus(PTT) ; and type 4, PTT with transvasal AP shunt, including the presence of cavernous transformation of the portal vein. RESULTS: Type I (n=20) showed hyperattenuation of both PTT and absent portal flow area on CTHA, and reciprocally consistent hypoattenuation on CTAP. Type II (n=6) showed a hypoattenuating area on CTHA, and isoattenuation or slightly hyperattenuation on CTAP. Type III (n=9) showed an oval or wedge-shaped hyperattenuating area on CTHA, anddefective perfusion at the same area on CTAP. In Type IV (n=13), both CTHA and CTAP showed variable findings, according to the amount of transvasal AP shunt, the location and extent of PTT, and/or cavernous transformation ofthe portal vein. CONCLUSION: Pattern analyses of hemodynamic changes on both CTHA and CTAP are helpful inclarifying the primary causes of hemodynamic changes in the liver.

Metastatic carcinoma of the eyelid is extremely rare; Oltmans reported the first case in 1930. We experienced a case of metastatic adenocarcinoma of the left lower eyelid in a 51-year-old male patient. The lesion was clinically similar to chalazion. Histopathologic findings of biopsy revealed gastric adenocarcinoma.
