This study was conducted to analyze the relations among nutritional knowledge, nutritional attitude eating practice and total nutritional diagnosis and also to find the influencing factors of them. The survey was done during the period from April 1990 to June 1990 and the target population were Ewha Woman's University students (freshmen and senior) of whom 1,354 peoples were surveyed. The summarized results are as follows ; 1. For the learning environment, the percentage of completion on nutritional knowledge course was 28.6% and among them the department of foods and nutrition had the highest score(100.0%) and the next was dept. of medicine(53.4%). 2. To find the relation which the nutritional knowledge, nutritional attitude, eating practice and the total nutritional diagnosis influence on one another, the multiple correlation analysis was done. The attitude the practice were highly correlated with total nutritional diagnosis, but the correlation between nutritional knowledge and total nutritional diagnosis was not significant. The correlation between the practice and nutritional knowledge which were positively and significantly correlated with attitude respectively was positive but not significant. 3. The difference which were analyzed by department, grade and completion on knowledge course on the nutritional knowledge, attitude, eating practice were significant (p<0.01) by ANOVA. 4. The significant variables on nutritional diagnosis are the eating practice points, the grade, the knowledge course, the breakfast and the attitude (r2=10.3%) by multiple regression analysis. This study has the limitation that it did not consider the environmental factors of dietary life such as dietary culture, family environment, cultural habit. Therefore important points of these dietary studies are to extend to the practical nutritional education and dietary improvement for the national health not restricted to the local area or local population.

The purpose of this study was examine the general characteristics of relapsed pulmonary tuberculous patients (i.e. age, sex, weight, occupation, previous forms of treatment, drug sensitivity, and the frequency of relapse) in order to improve future treatments of tuberculosis as well as to perpetuate health education. The data was obtained from the medical records of 186 relapsed pulmonary tuberculosis patients who were registered for treatment at various public health officers in Seoul during the year of 1994. The major findings obtained from the study were as follows; l) The male to female ratio of relapsed pulmonary tuberculous patients was about 7:3, more specifically 23.7% of the men and 30.9% of the women were between 20 and 29 years of age. 2) Comparing initial less aggravated states to relapsed states, patients with minimal x-ray findings later proved moderately advanced X-ray findings. Furthermore, patients with negative sputum AEB findings later proved positive sputum AFB findings. 3) of the l86 patients studied, 91.9% suffered, relapse and 8.1% suffered 2 or more relapses. Of the patients who suffered at least 1 relapse, 54.8% received short-term treatment, 26.9% received long-term treatment, and 18.3% received treatment of an unknown during their initial tuberculosis treatment periods. 4) Fifty five point four percent of the patients had no reaction to the drug treatment(not available), 25.9% of the patients had sensitive reaction to the drug treatment, 18.7% of the patients had resistant reaction to the drug treatment. Drug resistance was higher in patients to exhibited positive X-ray findings as well as in patients that exhibited positive sputum findings furthermore, patients receiving treatment of an unknown nature(35.5%) exhibited higher drug resistance than those receiving short-term treatment(13.6%) and long-term treatment(l7.0%). 5) Of the 160 patients who suffered relapses, 8.8% suffered a relapse within 1 year after treatment and 91.2% suffered a relapse at least 1 year after treatment. Furthermore, our study showed that women, under 30, who received short-term treatment and encounterd complications during their primary treatment suffered relapses faster than any other groups studied. In addition, minimal X-ray findings and sputum AFB findings were not correlated to the time relapse occurred. Therefore, the greater efforts are needed to prevent relapsed pulmonary tuberculosis.

STUDY DESIGN: A retrospective analysis was performed on 40 patients who had had previous lux bar spine surgeries. OBJECTIVE: To determine what factors most influenced surgical outcome and to analyze results in a series of revision lumbar surgeries. SUMMARY OF BACKGROUND DATA: Satisfactory surgical outcome of the revision lumbar surgery range from 28% to 82% and are rarely comparable to primary surgery. Many factors predicting outcome from repeat lumbar surgery haute been listed. METHODS: Forty patients were analyzed who had had previous lumbar surgeries. The patients were classified into 5 groups according to diagnosis: 3 Infection,5 instability,8 nonunion, 14 HNP and 10 spinal stenosis. of 40 patients,33 patients(82.5%) underwent fusion with instrumentation for repeat surgery. Their clinical course was followed for a minimum of 1 year. The number of surgery on each mpatient was 1.3 times on an average. RESULTS: Overall, 80% of patients had a satisfactory result. Obviously extruded or sequestrated HNP in MRI findings, complete block of contrast with severe radiculopathy and/or myelopathy in spinal stenosis, complete decompression, neurolysi s and fusion with instrumentation, and longer than 6 month pain relief after precious surgery were correlated with satisfactory outcome. However, the number of precious operation, age, repair of pseudarthrosis , no abnormality at surgery and combined multiple degenerative joint disease were significantly correlated with poor surgical outcome. The most common complication during repeat surgery was dural tear in 5 cases(12.5%). CONCLUSIONS: Success rate of revision surgery was low as compared to primary operation. Therefore, erroneous diagnosis and faulty surgical technique understandably lead to failure, and precise attention to preoperative and intraoperative detail can minimize these sources of error.

The formation of cysts in the parameatal area has been reported as rare. A parameatal urethral cyst is a congenital anomaly and has been reported even more rarely in adults. In this study, we present two cases of parameatal urethral cyst and aim to investigate their causes and treatment methods. The extent of cyst spread was assessed using a urethroscope prior to cyst excision, and the excision range was determined accordingly. Complete excision of the cyst was performed as the treatment for parameatal urethral cyst. Both patients were adults who presented with urinary symptoms related to the cyst, necessitating the excision of the congenital parameatal urethral cyst.

Subcutaneous panniculitic T-cell lymphoma is one of very rare diseases in children, which is presumably derived from various immunocompetent T-cell system components. It is a distinctive clinicopathologic entity, different from other lymphoma group. We report a case of subcutaneous panniculitic T-cell lymphoma in a 14-year-old boy with the complaints of fever and multiple subcutaneous nodule. A brief review of related literatures was also made.

BACKGROUND: The present study estimated healthcare costs of osteoporotic fractures including spine, hip, distal radius and humerus in Koreans over 50 years of age using national claims data. METHODS: Korea National Health Insurance data between 2008 and 2011 was searched for all claims records of outpatient visits or hospital admissions of patients ≥50-year-of-age. Osteoporosis-related fractures were identified using certain the International Classification of Diseases, Tenth Revision codes and site-specific physician claims for procedures in a patient age cut-off value of 50 years. The healthcare costs included acute phase costs accounting for emergency medical care given immediately after fracture, costs due to further hospitalization and surgical procedures, physiotherapy sessions according to the site of the fracture, and outpatient visits in the year after discharge. RESULTS: The total estimated healthcare costs of osteoporotic fractures in 2011 was $722 million. From 2008 to 2011, the total number and healthcare costs of osteoporotic fractures increased 28.9% (from 127,070 to 163,823) and 31.6% (from $549 million to $722 million), respectively. The portion of national health care expenditure was ranged from 2.3% in 2008 to 2.2% in 2011. The mean healthcare cost of osteoporotic fractures per person increased 2.1% from $4,321 in 2008 to $4,410 in 2011.The mean healthcare costs were highest for hip fractures followed by spine, humerus, and distal radius fractures. CONCLUSIONS: Total Healthcare costs of osteoporotic fractures in South Koreans ≥50-year-of-age increased between 2008 and 2011. This trend will likely continue, which is an important health problem in the elderly population and economically.

Gachon Medical School used an oral examination in the pathology course taught during the 2nd semester of the 2000 school year as a performance assessment of students abilities in three areas: comprehension, logic and problem solving. The evaluation instrument was designed in four stages: assessment objectives were determined, abilities to be measured were selected, the assessment instrument was designed, and the examiners' checklist was drafted. The assessment instrument included two gross and two microscopic cases and the checklist was developed using 5 Likert type scales. The students were divided into three groups of 12 to 13 students and two examiners were allocated to each group. The mean score on the oral examination was 3.56(the highest possible score is 5.00). The correlation between examiners was 0.952 while the correlation of gross and microscopic cases was 0.979. Obviously, these data are statistically significant. The correlation between the written examination pathologic-laboratory examination was the highest, that between the oral examination and pathologic-laboratory examination was in the middle, and that between the oral examination and the written examination was the lowest. Students expressed doubts about the objectivity of individual examiners. The high correlation between the examiners' scores and how students scored on other tasks shows that students fears can be assuaged. It is concluded that the oral examination is a powerful tool in measuring students ability, and can be used in a basic medical science course. As an assessment instrument, it is both valid and reliable.

Background: Long-term glucocorticoid use increases fracture risk by reducing bone mass. This study evaluated the relationship between hip and vertebral fractures and the total amount of systematic glucocorticoid use. Methods: We randomly selected 1,896,159 people aged 20 to 100 years who participated in the National Health Checkup program in 2006. The amount of glucocorticoids prescribed was calculated based on the defined daily dose (DDD). The total DDD was obtained by adding oral and parenteral glucocorticoids for 6 months from the index date. Subjects were categorized into four groups according to total glucocorticoid DDDs: non-users (DDDs=0), low users (0< DDDs ≤45), intermediate users (45< DDDs ≤90), and high users (90< DDDs). We followed them for 2 years. A multivariate Cox proportional hazard model was used to evaluate the effects of the total amount of glucocorticoid use on hip and vertebral fractures. Results: Higher glucocorticoid use was associated with a higher risk of vertebral fracture. Relative to non-users, the vertebral fracture risk was 1.39 times higher in the low-user group, 1.94 times higher in the intermediate-user group, and 2.43 times higher in the highuser group. The risk of hip fracture was 1.72 times higher in intermediate users and 3.28 times higher in high users than in non-users. Conclusion As the amount of glucocorticoid use for 6 months increased, the risk of hip and vertebral fractures became higher. In order to prevent fractures, it is necessary for doctors to evaluate the total amount of glucocorticoid prescribed to the patient and to provide appropriate treatment.

BACKGROUND: Endotoxin is a complex lipopolysaccharide molecule situated within the outer membrane of Gram-negative bacteria. Sepsis and acute respiratory failure (ARDS) can be induced by endotoxin. In order to introduce and develop the experimental model of ARDS in sepsis, we induced sepsis with the endotoxin and investigated the change of respiratory pathophysiology during sepsis using a multiple inert gas elimination technique (MIGET). METHODS: Ten New Zealand white rabbits were anesthetized and ventilated with a Harvard apparatus. In 5 rabbits, 2 mg/kg of lipopolysaccaride from E. coli was infused intravenously for 30 min (Toxin group). At 1, 2, 3, and 4 hours after endotoxin infusion, arterial blood gas, and hemodynamic profiles were checked. To perform the MIGET, six inert gases (SF6, krypton, desflurane, enflurane, diethyl ether, acetone) of widely varying solubility were infused peripherally and the excretion and retention data was determined from measurements of inert gas tensions in pulmonary arterial, systemic arterial blood samples and mixd expiratory gas sampling of pre and post septicemia using gas chromatography. We transformed and analysed the data into a V/Q distribution curve to find out the change of V/Q distribution curve. After the experiments, the animals were dissected and the lungs were extracted for wet/dry weight ratio (WW/DW) and microscopic examination. RESULTS: In the Toxin group, the pulmonary arterial pressures were increased and arterial oxygen tensions were decreased after the endotoxin infusion. The lung WW/DW were increased and inflammatory findings were seen in microscopic examination. In the MIGET, shunt, deadspace and log SDQ were increased in the toxin group, though there were wide V/Q distributions in the control group. CONCLUSIONS: We developed a successful endotoxin induced septic animal model, V/Q distribution curve and data using MIGET. The accomplishment of the experiment will not only allow us to better understand pulmonary pathophysiology of endotoxin induced sepsis using MIGET, but it will also contribute to other pulmonary physiology experiments associated with sepsis.
