Hormone replacement therapy combined with progestogens induces changes in effect of estrogen on serum lipid levels and it has been known that the changes depend on a type and dosage of progestogen. It is also known that progestational agent induces positive ch-ange in bone mineral density. To study the effects of progestogen on lipoprotein and bone metabolism, we administ- ered conjugated equine estrogen 0.625 mg alone to 50 postmenopausal women, in combinat- ion with medroxy- progesterone acetate 5 mg to 40 postmenopausal women. The data demonstrated a beneficial effect in lipoprotein profiles in both groups. Total cholesterol in two groups decreased from the baseline values, LDL-cholesterol decreased significantly by 4.8 % in group I and 16.2 % in group II(p < 0.05), HDL-cholesterol increa- sed significantly by 11.3 % in group I and 14.7 % in group II(p < 0.05), triglyceride incre- ased slightly in both groups. Bone mineral density of femur was maintained and BMD of vertebrae increased by 1.1 % in group I and 2.0 % in group II, but it is not statistically significant. The differences of changes between two groups were not statistically significa- nt. Our results suggest that medroxyprogesterone acetate have no adverse effect on HDL -cholesterol and have no additive effect on bone mineral density in hormone replacement therapy.

Renal arterial embolization has been utilized in the treatment of renal tumor since Lalli and associates introduced angioinfarction of kidney in 1996. To determine whether preoperative infarction facilitated an operation in the patients with renal cell carcinoma we compared 5 patients that were managed by standard radical nephrectomy to 7 patients in that preoperative infarction and radical nephrectomy had been used. And we performed infarction in 2 patients of inoperable renal cancer for conservative primary management. After we had performed infarction of kidney in 3 dogs experimentally, a total of 9 patients with renal cell carcinoma underwent angioinfarction of kidney at our department of urology. Radical nephrectomy was performed in 7 of total 9 patients. Complete cessation of renal arterial flow could be demonstrated in all cases and subsequent surgical dissection was facilitated after angioinfarction. We concluded that renal angioinfarction reduce the volume and vascularity of the tumor and because the resulting edema sharpens the tissue planes, it makes surgical resection easy and it is also useful therapeutic method in the patients with renal cell carcinoma who were not surgical candidates.

PURPOSE: The purpose of this study was to investigate factors associated with suspicious developmental delay in infants and early childhood. METHODS: Participants were 133 infants, aged from birth to 6 years old and their mothers, who were being seen at 16 Public health centers in B city. Korean Denver II was used to test infant development. chi2-test, Fisher's exact test and multiple logistic regression were used with SPSS 19.0 to analyze data. RESULTS: Of participant infants, 7.5% were below the 3rd percentile for the weight percentile, 8.4% is a weight curve that crosses more than 2 percentile lines on the growth charts after previous achievement, and 9.8% had suspicious developmental delay according to Korean Denver II. Further the predictive factors related to suspicious development delay in the children were decrease of weight percentile (Odds Ratio [OR]=6.69, Confidence Interval [CI])=1.22-36.45), low economic state (OR=6.26, CI=1.50-26.00), and developmental delay perceived by their mothers (OR=4.99, CI=1.24-20.06). CONCLUSION: It is necessary to build a government level system to follow management of development of infants and children from the time of birth. Especially, it is necessary to develop a program for children in low income families.

PURPOSE: The purpose of this study was to identify the risk factors for a nosocomial urinary tract infection in intensive care units with a foley catheterization which showed a positive urine culture. METHOD: Three-hundred eighty-seven patients were included in the study. A retrospective review of the electrical medical record system's databases and medical record sheets in hospitalized patients from January 2003 to December 2003 was used. The collected data was analyzed by descriptive statistics, t-test, chi-square test and logistic regression analysis. RESULT: The frequency of the participants' nosocomial urinary tract infection was 72.9%. Significant risk factors for a nosocomial urinary tract infection were 'age', 'place of catheter insertion', 'frequency of catheter change', and 'duration of catheterization'. These variables explained 18.4% of variance in the experience of nosocomial urinary tract infection in intensive care units with foley catheterization. CONCLUSION: Medical personnel can decrease the incidence of a nosocomial urinary tract infection by recognizing and paying attention to the duration of catheterization, frequency of catheter change, and place of catheter insertion. As a result, specific and scrupulous strategies should be developed to reflect these factors for decreasing nosocomial urinary tract infections.

PURPOSE: The purpose of this study was to identify nursing service costs associated with all health care costs incurred by the institution. METHODS: This study was an empirical case study research in which the nursing cost was separated from total medical cost. The nursing cost index was calculated through a cost allocation method after summarizing costs for personnel, raw materials and administration of each department in one public hospital. The 2014 budget plan, published in ‘Public Hospitals Alert’, was used as data and the data were analyzed using the Microsoft Office EXCEL 2013 program. RESULTS: When comparing total medical costs and nursing costs, the nursing cost were 27.14% of the total medical cost. The nursing cost per nurse per hour was calculated as ₩29,128 The nursing cost per inpatient per day was calculated as ₩157,970, and the administration cost per patient was calculated as ₩133,710. CONCLUSION: The results of the research present the process of cost allocation of specific cost elements in the hospital and evidence for administrative costs which in the past have been only vaguely formulated. These are the significant implications of this study.

OBJECTIVES: This study was designed to assess the change of heart rate variability (HRV) at resting, upright, and psychological stress in anxiety disorder patients. METHODS: HRV was measured at resting, upright, and psychological stress states in 60 anxiety disorder patients. We used visual analogue scale (VAS) score to assess tension and stress severity. Beck depression inventory (BDI) and state trait anxiety inventories I and II (STAI-I and II) were used to assess depression and anxiety severity. Differences between HRV indices were evaluated using paired t-tests. Gender difference analysis was accomplished with ANCOVA. RESULTS: SDNN (Standard deviation of normal RR intervals) and low frequency/high frequency (LF/HF) were significantly increased, while NN50, pNN50, and normalized HF (nHF) were significantly decreased in the upright position compared to resting state (p < 0.01). SDNN, root mean square of the differences of successive normal to normal intervals, and LF/HF were significantly increased, while nHF was significantly decreased in the psychological stress state compared to resting state (p < 0.01). SDNN, NN50, pNN50 were significantly lower in upright position compared to psychological stress and nVLF, nLF, nHF, and LF/HF showed no significant differences between them. CONCLUSION: The LF/HF ratio was significantly increased after both physical and psychological stress in anxiety disorder, but did not show a significant difference between these two stresses. Significant differences of SDNN, NN50, and pNN50 without any differences of nVLF, nLF, nHF, and LF/HF between two stresses might suggest that frequency domain analysis is more specific than time domain analysis.
