Chronic iron overload is associated with life-threatening complications, such as cardiomyopathy, liver cirrhosis, diabetes, hypothyroidism, hypoparathyroidism and hypogonadism. We experienced a case of secondary hemosiderosis with hepatic fibrosis in a 8-year-old boy who had been transfused 56 pints of packed red blood cells for a supportive therapy of acute myelogenous leukemia for a 27-month period. Intramuscular injection of Desferroxamine (40mg/kg/ day) was done for 9 months, however, there was no sign of improvement in hepatic size, consistency, and in liver biopsy findings. Except for mild thrmobocytopenia which seems to be the result of hypersplenism, the boy remained in remission for 3 2/3 years. We think, the prompt use of Desferroxamine therapy may be needed to avoid iron overload, if patients recieved multiple transfusions and high serum ferritin level.

The antihypertensive effect of trimazosin was studied in 24 cases of essential hypertension, which include 9 cases with pretreatment diastolic pressure of 114mmHg or more, for a period of 4 weeks. The average pretreatment systolic and diastolic blood pressures were approximately 175mmHg and 114mmHg, respectively. The treatment was started with 100mg of trimazosin daily in 2 divided doses and and the drug was titrated upward at weekly interval by 100mg up to 400mg/day depending on the response of the blood pressures. Routine blood counts, urinalyses, liver and kidney function tests, electrolyte balance, total serum cholesterol and triglyceride were determined before and at the end of treatment. The diastolic blood pressure fell 10mmHg or more in 20 out of 24 cases(83.3%), and in 12 cases out of 20 favorable responders it fell to 90mmHg or below. The pretreatment diastolic blood pressure in 4 nonresponders was all 115mmHg or more. The antihypertensive effect appeared during the first week of therapy and progressively increased until the end of treatment week without causing postural hypotension. Unpleasant symptoms appeared in 12 cases during treatment, which include dizziness, headache, numbness in the extremities and tinnitus in the decreasing order of frequency. However, these symptoms were mild and transient in all cases disappearing spontaneously despite continued medication. No significant biochemical changes in the blood were recorded after treatment. We conclude that trimzosin seems to be a safe and effective antihypertensive drug particularly useful for the treatment of mild to moderate hypertension.

Medical education in North Korea began with 2 medical colleges established during the 1930s and 1940s, and each Province came to have one medical college by the 1970s. It is presumed to exist 14 medical colleges in 1992. Apart from medical colleges, there are several kinds of medical schools. the number of medical practitioners has increased as the number of educational institutes for medicine increased. In 1996, there was 29.7 medical practitioners for 10,000 persons. They have several kinds of academic degrees in North Korea. They include: Wonsa, candidate Wonsa, doctor, vice-doctor, candidate doctor. In the university they have professor, associate professor, associate professor, lecturer, and research assistant. Academic degrees and positions are given not by the university nor research institute, but by the Government Board for Awarding Academic Degree and Position. Concerning research institutes, there is Chosen Institute for Medical Science that once was a medical research center under the Central Science Academy, and became an independent institute in 1963. Besides this institute, universities have their own research institutes, and there are also some other independent institutes.

The purpose of this study was to develop a critical pathway for case management of patients who have received Lumbar Laminectomy because of low back pain, arm and leg numbness, and radiating pain in the leg. For this study, a preliminary critical pathway was developed through a review of the literature including five critical pathways which are currently being used in the USA. In order to identify the overall service contents required by these patients, 30 cases were analyzed. These cases were taken from medical records of those with Lumbar Laminectomy between January, 1998 and December, 1998 in the department of neurosurgery at the Pusan National University Hospital in Pusan. An expert validity test was done for the preliminary critical pathway, a clinical validity test was also done using 12 patients with Lumbar Laminectomy between October 1, 1999 and January 31, 2000. After these processes, the final critical pathway was developed. The results are summarized as follows. 1. The vertical axis of the critical pathway includes the following eight items: assessment, consultation, diet, test, medication, treatment, activity, education/ discharge planning. The horizontal axis includes the time from the start of hospitalization to discharge. Analysis of the 30 medical records was done. analysis of the service contents showed the horizontal axis of the preliminary critical pathway was set from hospitalization to the 12th post operation day and the vertical axis was set to include eight items, the contents which should have occurred, according to the time frames of the horizontal axis. 2. As a result of the expert validity test, it was found that among the 233 items, 203 showed over 88% agreement and 30 of them showed less than 88% agreement, which were then revised or deleted from the critical pathway. At the preliminary meeting for the clinical validity test, the time of hospitalization on the horizontal axis was shortened to the 10th post operation day. A clinical validity test was done with 12 patients with Lumbar Laminectomy. All the cases progressed according to the critical pathway although some variances were noted in assessment, consultation, test, medication, and treatment. 3. Based on these results, a final critical pathway was determined. In conclusion, this critical pathway is partially applicable to the care of patients with Lumbar Laminectomy and needs further investigation.

If there is coronary plaque, do we need statin therapy? Many studies have been conducted to answer this question. According to global guidelines, there is a high-risk patient population who could benefit from statin therapy. According to the guidelines, patients with a history of previous cardiovascular disease are subject to statin therapy. In addition, several other studies have shown that asymptomatic coronary plaque could cause future cardiovascular events. Therefore, statin therapy could be considered in patients with coronary artery plaque. These coronary plaques can be quantified through invasive intra-coronary imaging equipment. Especially, vulnerable arteriosclerosis is the main cause of cardiovascular events. Use of statins in the presence of coronary plaques may help reduce atheroma volume and stabilize vulnerability. In conclusion, coronary artery imaging is very useful for the initiation and evaluation of statin therapy.

PURPOSE: The purpose of this study was to identify the influences of sleep quality and mood state on fatigue in primary brain tumor patients. METHODS: The participants were 118 patients with primary brain tumors between May 2015 and March 2016. Data were collected using questionnaires including individual and disease related characteristics, the Pittsburgh Sleep Quality Index, Linear Analogue Self-Assessment scales, and The Fatigue Scale for Cancer Patients developed by Kim Kyeong-hee (2006). Data were analyzed using descriptive statistics, Pearson correlation, and hierarchical multiple regression. RESULTS: Fatigue had significant correlations with sleep quality (r=.55, p<.001) and mood state (r=.74, p<.001). The influencing factors for fatigue were mood state (β=.46, p<.001) was the best predictor of fatigue, followed by age (β=.17, p=.049), and performance status (β=-.19, p=.011). CONCLUSION: The research findings show that understanding of psychological factors such as anxiety, depression, confusion, energy and anger should be given priority for fatigue management in primary brain tumor patients. This study provides base data for managing fatigue in patients with primary brain tumors, and is expected to contribute to the improvement of the health of patients with primary brain tumor.

OBJECTIVE: The purpose of this study was to evaluate the performance of OSTA (Osteoporosis Self assessment Tool for Asian) in Korean peri- and postmenopausal women. DESIGN AND METHODS: Total 1488 peri- and postmenopausal women over 45 years were included from Menopause Clinic in Chung-Ang University Hospital. Femoral neck BMD was measured by using DEXA (Lunar DPXIQ #7055). Three categories of bone status were defined by BMD based on the WHO definition. OSTA index values were calculated by using only 2 components such as age and weight. Three risk categories (high, medium, low) were classified according to index values. RESULTS: Seven hundred thirty women tested comprising 49.1% of all subject had low BMD (10.6% osteoporosis, 38.5% osteopenia respectively). The combined medium and high risk groups had a high prevalence (447/557=80.3%) of low bone mass. The medium and high risk groups had 85.5% of a high specificity, and 61.2% of a good sensitivity for identifying low bone mass. The medium and high risk groups also had 87.9% of a high sensitivity, and 68.5% of a good specificity for identifying osteoporosis. CONCLUSION: OSTA is a simple tool and easy to use, because it requires only age and weight. The OSTA risk tool performed well for identifying low bone mass, especially osteoporosis in Korean peri- and postmenopausal women.

The E-cadherin, alpha-catenin, and beta-catenin expressions were immunohistochemically investigated in paraffin-embedded materials of 80 cases of colorectal adenocarcinomas. The staining similar to normal colorectal mucosa with preserved strong membranous staining pattern was considered normal or preserved expression. The X2 test was used to analyse the statistical correlation of cadherin/catenin expression with clinicopathologic parameters and the Breslow test for the correlation with survival length. Normal colorectal mucosa showed strong membranous expression of cadherin/catenin complex. The reduced E-cadherin, alpha-catenin, and beta-catenin expression were found in 53/80 (66.3%), 46/80 (57.5%), and 44/80 (55.5%) cases of colorectal cancers examined, respectively. There were significant correlations between E- cadherin and alpha -catenin (p=0.035), and between alpha-catenin and beta-catenin (p=0.013). The reduced E-cadherin expression was associated with histologic dedifferentiation, tumor depth, lymph node metastasis, clinical stage (p<0.05), poor clinical outcome in stage II (p=0.016) and the reduced alpha-catenin expression with lymph node metastasis and clinical stage (p<0.05). Reduced expression of two or more proteins was correlated with lymph node matastasis, histologic dedifferentiation, clinical stage, and survival (p<0.05). The present study demonstrates a significant down-regulation of E-cadherin and alpha-catenin expression in colorectal cancer is associated with tumor invasiveness, histologic dedifferentiation, lymph node metastasis, and clinical stage. These results suggest that E-cadherin and alpha-catenin may be useful markers of invasiveness, lymph node metastatic potential, and clinical stage and of value as prognostic markers in the earlier stage. Further studies are needed to confirm the prognostic value of these cadherin/catenin complex.
