OBJECTIVES: Over the last 30 years, despite the increasing sophistication in medical care, the mortality of acute renal failure(ARF) has remained virtually unchanged at 40-50%, but the reasons remain unknown. This study intend to identify prognostic risk factors influencing survival and predict the mortality in ARF patients. METHODS: We retrospectively analyzed 152 patients with ARF who required renal replacement therapy, or whose serum creatinine level above 5 mg/dl, from Jan. 1988 to May. 1995. Multiple factors which may influence mortality were evaluated by univariate and multivariate analysis. RESULTS: 1) Of the 152 patients, 97 were male and 55 were female. The mean age was 47 years and the overall mortality was 36.8%. 2) Based on the univariate analysis, age>60 years, cause of ARF, APACHE II score, number of failing organs, peak serum creatinine level, PaO2, coma, hypotension, ARDS, GI bleeding, ventilatory support, need for antiarrhythmics, DIC, cardiovascular failure, pulmonary failure, neurological failure, and gastrointestinal failure were all significant factors discriminating between survivors and nonsurvivors(p<0.05) 3) By multivariate analysis, hypotension, coma, ventilatory support, and age over 60 years were significant independent predictors influencing survival in ARF patients and logistic equation and logit score were as follows : z=-2.04+1.32(age over 60)+2.18(hypotension)+2.88 (ventilatory support) + 3.28(coma) P=ez/(1+ ez) 4) In ROC(receiver-operating characteristic)curve, when the cutoff point was 0.2, maximum sensitivity was 75% and maximum specificity was 82%. CONCLUSION: In ARF, prognostic risk factors for mortality were age over 60 years, hypotension, assisted ventilation and coma. The logit score by multiple analysis is a reliable predictor of mortality in ARF patients, however the further studies are required to confirm these results.

This study was conducted to investigate the status of pregnancy and delivery and relationship among knowledge, attitude and practice about pregnancy and delivery in poor country, Nepal. A questionnaire survey by interviewer was conducted to examine the general characteristics, knowledge about pregnancy and delivery, attitude about pregnancy and delivery, the rate of prenatal care and delivery condition of women who had an experience of delivery during last year(1994. 4. 13~1995. 4. 12) at a rural area, nepal(Dolakha Bazar Area). The major findings are as follows; Among respondents, 87.5 percentage never had health education and the degree of knowledge about pregnancy and delivery was low. Among respondents, 56.6 percentage had the attitude that they didn't want antenatal care, 42.8% of respondents answered that they wouldn't visit hospital or health center when vaginal bleeding occurred and 82.9% thought that the delivery itself was dirty. The proportion of women who experienced antenatal care was 28.3%, the proportion of health facilities delivery was 5.3%, which was very low and 82.6% of home delivery case didn't sanitate the tool to cut the umbilical cord. The women who had positive attitude about antenatal care and health facility utilization experienced more antenatal care and health facilities delivery. On consideration of above findings, health education for pregnancy and delivery is required to improve mother-child health status in poor country. To make efficient health education, the target population group, such as the uneducated, inhabitants far from health center or medical facility, must be chosen. To help the poor countries in medical field, the study on health status and its related factors on these countries like this article would be required.

6.The cephalometric study on the depth of the mandibular antegonial notch as on indicator of mandibular growth pattern.
Korean Journal of Orthodontics 1989;19(1):77-93
The purpose of the present study were to disclose whether the depth of the mandibular antegonial notch can be used as an indicator of mandibular growth potential. The patients composed of 76 samples and were classified following 3 groups, based on the depth of mandibular antegonial notch: Deep notch group (more than 3mm), Neutral notch group (1-3mm), Shallow notch group (less than 1mm). For each case, the first lateral cephalograms were taken prior to the start of treatment and the second films 3-4 years after. The results were as follows; 1. Deep notch group had a shorter corpus, less ramus height and greater gonial angle than did Shallow notch group. 2. Deep notch group had a more retrusive mandibular position than Shallow notch group. 3. Deep notch group had longer total anterior facial height and longer anterior lower facial height group. 4. Deep notch group grow vertical clockwise growth pattern, while Shallow notch group grow horizontal counterclockwise growth pattern. 5. Deep notch group had less mandibular growth than Shallow notch group during observation period.

Lipoma arborescens is a rare intra-articular lesion consisting of a villous lipomatous proliferation of the synovial lining. We experienced one case of lipoma arborescens of knee which was associated with avascular necrosis of femoral head. This case report draws the attention to history, physical findings, MR images, pathologic findings and arthroscopic appearance of this rare lesion. Arthro;copically, the lesion appears as a synovial lesion with numerous fatty-appearing globules and villous projections. Although the etiology is unknown, lipoma arborescens has been described in association with osteoarthritis, rheumatoid arthritis and diabetes mellitus. MR imaging is diagnostic choice to differentiate the lesion from rheumatoid arthritis, pigmented villonodular synovitis and synovial chondromatosis in those patients who present with chronic, swollen and painfui joint. Arthroscopic removal was effective in this case and we think that treatment choice of this lesion is arthroscopic removal.

The mineral content and width of bone can be determined noninvasively by “bone densitometer”, which measures the absorption by bone of a monoenergetic photon beam that originates in a radioactive source(Iodine-125 at 27.3 Kev). The intensity of the beam transmitted by the bone is measured by a scintillation detector. The bone mineral density is obtained from dividing the bone mineral content by bone width. Since Cameron and Sorenson, in 1963, first described the photon absorptiometry, many investigators have studied this method and applied it clinically. In order to determine the bone density of normal koreans, and compare it with that of fracture risk group, we measured the bone density of the distal one third of the nondominant radius in 152 normal persons(55 male, 97 female), and 54 patients(23 male, 31 female) having the risk of spontaneous fracture from the third to seventh decades. This data were also compared with those of normal Caucasians. The results were as follows. 1. The average bone densities(gm/cm2) of normal men from the third to the seventh decades were 0.773 ±0.055, 0.749 ±0.070, 0.770 ±0.060, 0.797 ±0.053, 0.664 ±0.126, respectively and those of normal women were 0.680 ±0.058, 0.680 ±0.036, 0.674 ±0.052, 0.608 ±0.084, 0.523 ±0.093, respectively. 2. The average bone densitied(gm/cm2) of fracture risk men from the third to seventh decades were 0.647 ±0.072, 0.719 ±0.050, 0.729 ±0.085, 0.699 ±0.064, 0.562 ±0.049, respectively and those of fracture risk women were 0.603 ±0.049, 0.061 ±0.021, 0.326 ±0.034, 0.494 ±0.045, 0.430 ±0.035, respectively. 3. There were statistically significantly differences in the bone densities between the normal population group and the fracture risk group. 4. The average bone densities(gm/cm2) of normal koreans were lower than those of normal Caucasians by 0.115 ±0.023 in male, and 0.091 ±0.005 in female. 5. We belive that bone densitometer is an effective tool in early detection and treatment in metabolic bone deseass including osteoporosis.

PURPOSE: It is known that single umbilical artery is frequently associated with gastrointestinal or urogenital anomaly, however, routine renal sonography has been debated in healthy neonate with isolated single umbilical artery. This study is designed to determine the usefulness of routine renal sonography in apparently healthy infants with an isolated single umbilical artery. METHODS: Thirty healthy neonates with a single umbilical artery without a major anomaly from January 1995 to July 2002 were enrolled. The authors investigated the clinical background of babies and their mothers after renal sonography after 72 hours of age. When the abnormalities were found at the first renal sonography, the severity of hydronephrosis and degree of obstruction and renal function were analyzed by follow up renal sonography, voiding cystourethrography(VCUG) and technetium-99m-dimercaptosuccinic acid(DMSA) scan or technetium-99m-mercaptoacetyl-triglycerine (MAG3) scan. RESULTS: Among the 30 healthy patients with isolated single umbilical artery, five patients(16.7%) showed abnormalities on first renal sonography with one major(3.3%) and four(13.4%) minor renal anomaly(minimal or mild hydroneohrosis). One major renal anomaly(severe hydronephrosis) showed severe decreased renal function on MAG3 scan without reflux, and the other four minor regressed spontaneously on follow up study. CONCLUSION: The value of routine early renal sonograpy for detecting renal anomaly in healthy infants with an isolated single umbilical artery remained unclear because most of the anomalies would regress spontaneously in the follow up study.
