PURPOSE: This study was undertaken to identify the frequencies and the risk factors of microvascular complications in subjects with type 1 diabetes mellitus METHODS: The frequencies and their relation to risk factors of microvascular complications were analyzed in 29 type 1 diabetes mellitus subjects with duration of disease more than 5 years. Microvascular disease was defined as the presence of either retinopathy, microalbuminuria or neuropathy. RESULTS: The overall prevalence rate of microvascular disease was 8/29(27.6%). Retinopathy has developed in 3 patients(10.3%), microalbuminuria in 7 patients(24.0 %) and neuropathy in 5 patients(17.2%). The mean HbA1C was significantly higher in the patients with microvascular complications(11.6+/-.2% in microvascular complication group vs 9.3+/-.6% in control group). CONCLUSION: In childhood onset type 1 diabetes mellitus, poor glycemic control is an important risk factor for microvascular complications.

BACKGROUND: Obesity is a risk factor of hyperlipidemia, DM, hypertension and cardiovascular diseases. In clinical practice the evaluation of obesity has been done indirectly by anthropomet ric indices such as BMI, waist to hip ratio, waist and hip circumference. This study was attempted to show whether waist circumference is better simple anthropometric index of abdominal obesity and has better correlation of metabolic profile than waist to hip ratio which has been commonly used. METHODS: We gathered 286 cases who have undergone medical examination from May 1997 to July 1997 at Dankook University Hospital and measured BMI, relative ideal body weight by Modified Broca method, waist circumference, waist to hip ratio, metabolic profiles, fasting blood sugar, systolic and diastolic blood pressure. RESULTS: Waist to hip ratio and waist circumference showed high correlation with BMI and Modified Broca index. In men, correlation coefficient of waist circumference and waist to hip ratio with BMI was r=0.761, r=0.467, and correlation coefficient of waist circumference and waist to hip ratio with Modified Broca index was r=0.726, r=0.458. In women, correlation coefficient of waist circumference and waist to hip ratio with BMI was r=0.791, r=0.628, and correlation coeffience of waist circumference and waist to hip ratio with Modified Broca index was r=0.769 r=0.660. This finding showed waist to hip ratio and waist circumference is more closely related to BMI and Modified Broca index in women than men and showed higher correlation with waist circumference than waist to hip ratio. There were significant differences of correlation coefficient of obesity indices between waist circumference and waist to hip ratio (p<0.00001). Waist circumference showed relatively significant correlation with metabolic profiles, but we could not observe high correlation coefficient. But there was significant difference of distribution between normal group and obese group defined as BMI>25 and modified Broca index>120%. CONCLUSION: Waist circumference, index of abdominal obesity has better correlation with obesity indices than waist to hip ratio and is a simpler method.

PURPOSE: Communication in hospitals is one of the major factors in patient safety. So, the purpose of this study was to identify the relationship between intra-organizational communication satisfaction and the safety attitude of nurses in hospitals. METHOD: A descriptive survey design with convenience sampling was used. Data collection was done using a self-report questionnaire answered by 278 nurses from one university hospital located in Kyeoung-gi Province, Korea. RESULT: Intra-organizational communication satisfaction positively correlated with safety attitude (r=.747, p<.01). Among the 6 sub dimensions of safety attitude, perceptions of management (r=.675, p<.01), job satisfaction (r=.640, p<.01) and teamwork climate (r=.600. p<.01) were strongly related to intra-organizational communication satisfaction. Multiple regression analysis was done to identify explanation power of intra-organizational communication satisfaction against safety attitude. The model was significant (F=48.540, p<.01). Intra-organizational communication satisfaction accounted for 60.9% of variance in safety attitude (Adj R2=.609). CONCLUSIONS: The results of this study indicate that higher levels of intra-organizational communication satisfaction promote positive safety attitude in hospital nurses and that communication media quality is an important factor in patient safety attitude. Therefore, developing interventions to revitalize intra-organizational communication level based on communication media quality will help in the construction of positive safety attitude in nurses.

Dysembryoplastic neuroepithelial tumor(DNET) is a recently described rare tumor that occurs most frequently in the temporal lobe of the brain and is characterized by long-standing, intractable complex partial seizures in children. The authors experienced one case of DNET occurring in a 13-year old boy, who had refractory complex partial seizure for 7 years. CT scan revealed nonenhancing low density mass in the left temporal lobe. MR images demonstrated a well-marginated cortical mass with very low signal intensity on TIWI and multinodular appearance of high signal intensity on T2WI. A few small enhancing foci within the mass were noted on contrast enhanced MR images. DNET, a rare tumor, should be considered in the differential diagnosis of neoplasm which causes seizure and is distinguished from other tumors because of its benign course. Differentiation between DN ETand other tumors by CT and MR findings is very difficult. But, our case showed the multinodular pattern on T2W image, which may be helpful feature in the differential diagnosis.

OBJECTIVES: To determine the level of mRNA expression of various members of the matrix metalloproteinase and tissue inhibitors in uterine leiomyoma compared with unaffected myometrium. Materials & Method: 30 cases of portions of leiomyoma and myometrium were collected immediately followimg hysterectomy. Thirteen cases were from proliferative phase and seventeen were from secretory phase of menstrual cycle. The mean age was 43.7years old. The level of expression of mRNAs of interstitial collagenase, gelatinase, stromelysin, TIMP-1,-2,-3 was determined by reverse transcriptase-polymerase chain reaction(RT-PCR) and normalized to GAPDH(glyceraldehyde-3-phosphate dehydrogenase) mRNA. RESULTS: Myometrium and leiomyoma expressed all the members of above mentioned matrix metalloproteinase family and tissue inhibitors. Leiomyoma expressed a significantly higher level of stromelysin-3 during secretory phase, an extremely lower level of 92kDa gelatinase and a significantly lower level of TIMP-3. The immunohistochemical localization of TIMP-3 was smooth muscle cell and arteriole wall of myometrium and leiomyoma. CONCLUSIONS: The increased expression of stromelysin-3 in uterine leiomyoma compared with myometrium suggests that this MMP may be involved in the formation of a more fibrous extracellular matrix in leiomyoma. The extremely lower expression of 92kDa gelatinase of leiomyoma means that leiomyoma do not invade myometrium and forms a separated mass. Decreased expression of TIMP-3 of leiomyoma suggests that TIMP-3 is required for differentiation and homeostasis of extracellular matrix of normal myometrium and function as a suppressive role of tumor development

PURPOSE: The purpose of this descriptive study was to identify the impact of workplace bullying and LMX (Leader-Member Exchange) on turnover intention among nurses. METHODS: The participants were 364 nurses from the Seoul metropolitan area who were attending a continuing education program. A structured questionnaire was used for data collection and data were analyzed using the SPSS/Window program. Hierarchical multiple regression analysis was performed to verify the effect of variables on turnover intention. RESULTS: Higher workplace bullying was associated with higher turnover intention. Workplace bullying was negatively correlated with leader-member exchange. The most influential factors for turnover intention were LMX (beta=-7.22, p<.001), work load (beta=2.96, p=.003), and workplace bullying (beta=2.64, p=.009). These factors accounted for 28% of the variance in turnover intention. CONCLUSION: The study results indicate that there is need to develop strategies to prevent workplace bullying and cultivate a good relationship between nursing managers and nurses to lower nurses' turnover intention.

Removal of blunt esophageal foreign bodies using Foley catheter under a fluoroscopic guidance is a well-recognized procedure. However, since this procedure is rather cumbersome and uncomfortable to the patient, the authors tried to find an easier and more convenient modified technique. For 10 patients with esophageal foreign body, we tried the method to the patients who is lying in the right lateral decubitus position and 3 assistants hold head. arms, trunk and legs of the patients without tilting the table and without using immobilizer. Foley catheter is inserted through nostril, nasal cavity and pharynx to esophagus. In order to identify the Foley catheter in esophagus, 0.025 inch short wire was inserted in the Foley catheter. The balloon of a Foley catheter was inflated by 10cc of air, and the syringe was kept attached to the Foley catheter during the procedure. After passage of the foreign body through the upper esophageal sphincter, the balloon was deflated immediately and the foreign body was removed through the mouth. We successfully removed in removing all the blunt esophageal foreign body with ease. This modified method is also fast, safe and efficient.
