Osteochondroma is the most common of the benign bone tumors. They are probably developmental malformations rather than true neoplasms. But rarely they develope in a joint, especially in the ankle joint. We reported a case of intraarticular osteochondromatosis of ankle joint.

BACKGROUND: Diabetic ketoacidosis(DKA) is serious acute metabolic complication and the most important cause of high morbidity and mortality of diabetes. The object of this study is to examine the clinical characteristics of patients with DKA who had a prior history of diabetes or not. METHOD: Authors reviewed retrospectively the medical records of 49 cases adimitted to Kyungpook National University Hospital from January 1991 to June 1997 with a diagnosis of DKA and classified cases as type I, type II and newly diagnosed diabetics according to prior history of diabetes. RESULTS: 1. Of 49 cases of DKA, 24(49%) were classified as type I, 17(35%) as type II from data available in the medical records, and 8(16%) had DKA as the initial manifestation of the disease. 2. The male to female ratio was 0.5 : 1 in type I, 1.1 : 1 in type II and 1.7 : 1 in newly diagnosed diabetics, and the mean age was 24.4 in type I, 57.9 in type II and 23.9 years old in newly diagnosed diabetics. 3. The mean duration between initial diagnosis of diabetes and the occurrence of DKA was 2.6 in type I and 6.9 years in type II diabetes. The occurrence of DKA within 2 years of initial diagnosis of diabetes was 54% in type I and 18% in type II diabetes, but the occurrence of DKA after 5 years of initial diagnosis of diabetes was 17% in type I and 47% in type II diabetes. 4. The precipitating factors of DKA were identified in 88% in type I, 76% in type II and 38% in newly diagnosed diabetics, and the most common precipitating factor was omission of treatment in both type I and type II(type I: 56%, type II: 35%). 5. The altered mental status was correlated with increased osmolality (p<0.05), but not with other laboratory values such as pH, bicabonate, glucose, anion gap and dehydration status(p>0.05). CONCLUSION: It is necessary to conduct early aggressive evaluation for early diagnosis and proper treatment of DKA, because DKA occurs in patients with prior history of type II diabetes and without prior diabetic history as well as patients with prior history of type I diabetes.

BACKGROUND: In patients of sepsis, especially combined with multiple organ failure syndrome, the whole body oxygen consumption is delivery dependent even above the critical oxgen delivery. This phenomenon is named as 'pathologic oxygen delivery dependency'. Multiple organ failure syndrome is characterized by maldistribution of oxygen delivery, tissue oxygen diffusion disturbance and inability of oxidative phosphorylation of anaerobic metabolites owing to hepatic failure. In liver transplantation, the anhepatic phase is characterized by uneven microperfusion due to surgical manipulation and 'total hepatic failure'. We hypothesized that there might be oxygen delivery dependency in anhepatic phase of liver transplantation. METHODS: In 14 canine orthotopic liver transplantations, whole body oxygen delivery (DO2) and oxygen consumption (VO2) were calculated as the product of cardiac output and, arterial oxygen content and arterial-venous oxygen content difference, respectively, according to the operative phases. Then the relationship between DO2 and VO2 was analyzed by correlation analysis in each operative phases. RESULTS: In control and four reperfusion phases no significant correlation was found. But in two anhepatic phases (10 minutes after inferior vena cava cross clamping, 5 minutes before reperfusion), significant correlation was found (R=0.79, 0.72, p<0.005, 0.01 repectively). In postinduction phase (50 minutes after induction), significant correlation was found (R=0.62, p<0.05), but strength of correlation was lower. CONCLUSIONS: This study showed the oxygen delivery dependency in anhepatic phase of liver transplantation. Therefore supranormal oxygen supply advocated in multiple organ failure syndrome and sepsis might be applicable to management of anhepatic phase of selected recipients.

OBJECTIVES: This study was intended to investigate the differences of job stressors between managers and low level employees among white-collar workers. Another objective of this study was to examine whether the effects of job stressors on mental health differ between the two groups. METHODS: Data was obtained from 204 managers and 251 low level employees who were employed in white-collar jobs. Fourteen job stressors and seven job stress variables were measured. RESULTS: Among the 14 job stressors, role overload, job insecurity, and work-family conflict were higher job stressors for the manager group whereas role conflict, work-aptitude incongruity, participation in decision making, and promotion problems were higher job stressors for the low level of employees. There were no differences in job stress scores between the two groups. However, differences in the effects of job stressors on job stress were found between the two groups. For the manager group, job insecurity, work-aptitude incongruity, and work-family conflict significantly affected in explanation of job stress whereas for the low level employees, role underload, peer satisfaction, and environmental problems significantly explaining the job stress variables. CONCLUSIONS: There were significant differences in job stressors between managers and low level employees among white-collar workers. Additionally there were differences in the effects of job stressors on job stress between the two groups.
