The purpose of this study is to investigate factors related to the intent of using home nursing of chronic disease patients who got out of a university hospital. For the purpose. the study selected 153 patients who were hospitalized and left K university hospital with diagnoses of cancer. hypertension. diabetes and cerebral vascular accident and ordered to be discharged and performed interviews with them and surveys on their medical records to obtain the following results. For this study a direct-interview survey and medical record review was conducted from June 28 to Aug. 30. 1998. The frequency and mean values were computed to find the characteristics of the study subjects. and chi-test. t-test. factor analysis and multiple logistic regession analysis were applied for the analysis of the data. The following results were obtained. 1) When characteristics of the subjects were examined. men and women occupied for 58.8 % and 41.2 %. respectively. The subjects were 41.3 years old in average and had the monthly average earning of 0.99 million won or below. which was the most out of the total subjects at 34.6 %. Among the total. 87.6% resided in cities and 12.4 in counties. The most left the hospital with diagnosis of cancer at 51.6 %. followed by hypertension at 24.2%. diabetes at 13.7% and cerebral vascular accident at 7.2%. 2) 93.5% of the selected patients had the intent of using home nursing and 6.5%. didn't. Among those patients having the intent. 85.6% had the intent of paying for home nursing and 14.4%. didn't. The subjects expected that the nursing would be paid 9.143 won in average and 47.7 % of them preferred national authorities as the mam servers. 86.3% of the subjects thought that home nursing business had the main advantage of making it possible to learn nursing methods at home and thereby contributing to improving the ability of patients and their facilities to solve health problems. 3) Relations between the intent of use and characteristics of the subjects such as demography-related social. home environment. disease and physical function characteristics did not show statistically significant differences among one another. Compared to those who had no intent of using home nursing. the group having the intent had more cases of male patients. the age of 39 or below. residence in cities. 5 family members or more, no existence of home nursing servers, leaving the hospital from a non-hospitalized building, disease development for five months or below, hospitalization for ten days or more, non-hospitalization within the recent one month, two times or over of hospitalization, leaving the hospital with no demand of special treatment, operation underwent, poor results of treatment, leaving the hospital with demand of rehabilitation services, physical disablement and high evaluation point of daily life. 4) Among those patients having the intent of using home nursing, 47.6% demanded technical nursing and 55.9%, supportive nursing. As technical nursing, 'inject into a blood vessel' and 'treat pustule and teach basic prevention methods occupied for 57.4%, respectively, topping the list. Among demands of supportive nursing, 'observe patients' status and refer them to hospitals or community resources as available, if necessary' was the most with percentage point of 59.5. Regarding the intent of paying for home nursing, 39.2% of those patients wishing to use the nursing responded paying for technical services and 20.2, supportive services. In detail. 70.0% wanted to pay for a service stated as 'inject into a blood vessel' , highest among the former services and 30.7%, a service referred to as 'teaching exercises needed to make the body of patients move', highest among the latter. When this was analyzed in terms of a relation between the need(the need for home nursing) and the demand(the intent of paying for home nursing), The rate of the need to the demand was found two or three times higher in technical nursing(0.82) than in supportive nursing(0.35). In aspects of technical nursing, muscle injection(0.26, the 1st rank) was highest in the rate while among aspects of supportive nursing. a service referred to as 'teach exercises needed for making patients move their bodies normally' (0.58, the 1st rank). 5) factors I(satisfaction with hospital services), II(recognition of disease state), III(economy) and IV(period of disease) occupied for 34.4, 13.8, 11.9 and 9.2 percents, respectively among factors related to the intent by the subjects of using home nursing, totaled 59.3%. In conclusion, most of chronic disease patients have the intent of using hospital-based home nursing and satisfaction with hospital services is a factor affecting the intent most. Thus a post-management system is needed to continue providing health management to those patients after they leave the hospital. Further, supportive services should be provided in order that those who are satisfied with hospital services return to their community and live their independent lives. Based on these results, the researcher would make the following recommendation. 1) Because home nursing becomes more and more needed due to a sharp increase in chronic disease patients and elderly people, related rules and regulations should be made and implemented. 2) Hospital nurses specializing in home nursing should be cultivated.

Histiocytosis-X is a term used to define three diseases with similar morphologic characteristics : Letterer-Siwe diseae, Hand-Schuller-Christian disease and Eosinophilic granuloma. In general, they differ in terms of their age of onset, severity of clinical course and site of involvement. Eosinophilic granuloma typically is seen in young adults. Eosinophilic granuloma is diagnosed in the presense of diffuse pulmonary infiltrate, bony involvement. However, the Pulmonary radiologic findings of eosinophilic granuloma are variable accordinary to stage of disease. therefore pathologic diagnosis of involving site is essential for confirmative diagnosis of eosinophilic grananuloma. Pathologically. the three disease are characterized by granulomatous infiltration of alveolar septa and bronchial walls and often involvement of bone. The hallmark of this disease is proliferation of the Langerhans' cell. The identifying feature is the X-body or Birbeck granule that is present in Langerhans' cells and histiocytic cells found in the lung of EG patient. We report a case of bilateral, recurrent and spontaneous pneumothoraces in a 21 year old man with pulmonary histiocytosis-X which is confined by eosinophilc granuloma in bone marrow biopsy and ultrastructural examination in cells obtained from BAL.

PURPOSE: Most of childhood MCNS has a long disease course with frequent relapses. This study was designed to analyze the long-term clinical course of childhood MCNS, focusing at relapsing pattern, treatment response and complications. Mothods : The medical records of 137 children with biopsy-proven MCNS observed during 1976 ti 1996 were analyzed retrospectively. They were classified as initial responders (111 patients, 81%) and nonresponders (26 patients, 19%) according to the response to initial oral prednisolone (60mg/m2/d) for 4 weeks. The detailed clinical courses were obtained in 126 patients. RESULTS: The incidences of hematuria, hypertension and azotemia were more frequent in initial responders than nonresponders. During follow-up, the proportion of patients with sustained remission increased gradually with decreasing rate of relapse. At the last follow-up, 77 patients (61%) revealed sustained remission, 36 (29%) repeated relapses, 9 (7%) persistent proteinuria, 3 (2%) renal failure, and 1 (1%) death. The responses to secondary drugs such as first and second course of cyclophosphamide, cyclosporin, levamisole and methylprednisolone pulse were 80%, 85.7%, 70%, 75%, and 40%, respectively. Major complications were infections including peritonitis (29 patients) and acute renal failure (10) patients.CONCLUSION: Long-term prognosis of childhood MCNS is determined by clinical courses rather than renal pathology. Although majority of childhood MCNS reveal good long-term prognosis, patients did well, few patients do not so. Early detection and more aggressive therapy of such patients are very helpful.

OBJECTIVES: Differential diagnosis based on descriptive psychopathology between bipolar and unipolar depression in the clinical setting is a still huge challenge. Projective psychological tests might provide additional clues. This study aimed to find distinct Rorschach test characteristics of bipolar depression in comparison with unipolar depression. METHODS: Medical records and raw data of the Rorschach Inkblot test applied using standardized procedure for the Exner Comprehensive System were retrospectively reviewed for patients with bipolar disorder or unipolar depression. Individual variables of the Rorchach test were compared among three groups, i.e., (hypo) mania (n=59), bipolar depression (n=56) and unipolar depression (n=25). RESULTS: Bipolar depression group, in accordance with (hypo) manic group, showed more color reponses (WSumC), more extroverted and intuitive decision-making (EBright), and higher emotional expression (CF+C) and instability (ebright), compared to unipolar deperssion group. On the contrary, the (hypo) mania group displayed more cognitive errors (Sum6, WSum6) compared to both depression groups. CONCLUSION: This study suggests that Rorchach test might provide valuable markers for differential diagnosis between bipolar and unipolar depression, and that some of those markers could be regarded as trait markers of bipolar disorder.

Background: Post-cardiac arrest syndrome (PCAS) is one of the critical conditions which can result in a more serious brain injury. Early and accurate prognostication is crucial for deciding the patient’s therapeutic plan and setting the treatment goal. This study aimed to establish the prognostication values of quantitative electroencephalography (QEEG) in PCAS patients. Methods: We recruited 183 PCAS patients treated with therapeutic hypothermia. Electroencephalography (EEG) data within 72 hours after cardiac arrest (CA) and clinical data were collected. QEEG analysis including power spectral density (PSD) and connectivity analysis of default mode network (DMN) with imaginary coherence were performed. Results: There were significantly different patterns of PSD between neurologic good and poor outcome groups; absolute and relative power of the alpha 2 and beta 1 frequency (10-15 Hz) bands were increased in all brain regions of good outcome group. However, the relative power of the delta band and higher frequency bands over fast alpha (beta 3 and gamma bands over 20 Hz) were poor outcome markers. We found out that connectivity of DMN were significantly decreased in the poor outcome group compared with the good outcome group. Conclusions These findings suggest that QEEG analysis could quantify and automate the interpretation of EEG. Furthermore, they can improve the prognostic values for neurologic outcomes relatively accurately and objectively in PCAS patients treated with hypothermia compared with traditional visual grading.

Cold agglutinin disease (CAD) is a most common autoimmune hemolytic anemia (AIHA) induced by cold antibody. CAD represents approximately 16-32% of AIHA cases and causative cold autoantibodies commonly show specificity against the I antigen. We report a case of cold agglutinin disease with anti-Pr cold autohemolysin. A 20 year old woman with a history of bone marrow transplantation was admitted with nausea, vomiting, and pallor. Direct antiglobulin tests were positive with IgG and C3d specific AHG reagents. Cold agglutinin titer was as high as 1:1024 at 4degrees C, 1:16 at room temperature, negative at 37degrees C. The agglutinin titer was diminished after treatment with protease, ficin and immunohematologic results of cold agglutinin was compatible with anti-Pr specificity. In unexpected antibody identification test, anti-M which showed reactivity at anti-human globulin phase was identified. Washed and prewarmed 16 units of A+, M antigen negative red blood cells were transfused. After two weeks, patient was improved with steroid therapy and experienced relief of fever and hemolysis, and she was discharged.

Objectives: The objective of this study was to develop models for predicting obstructive sleep apnea (OSA) based on easily obtainable clinical information of patients using various machine learning techniques. Methods: We used a data set that included the records of 1,368 patients, in which 1,074 patients were male (78.5 %), and 294 patients were female (21.5 %). We randomly divided the data into a training set (1,000) and test set (368). Five machine learning methods, i.e., support vector machine model, lasso logit model, naïve bayes, discriminant analysis, and K-nearest neighbor (KNN), with a 10-cross fold technique were used with the proposed model to predict OSA. We evaluated the accuracy, sensitivity, specificity, and precision of each model for three thresholds [Apnea-Hypopnea Index (AHI)≥5, AHI≥15, and AHI≥30]. Results: Among the machine learning techniques, KNN showed the best results compared to the other techniques. The accuracy, sensitivity, specificity, and precision of OSA prediction were 87.0%, 91.0%, 74.4%, and 91.9%, respectively, based on AHI≥5. When the threshold of OSA was AHI≥15 or AHI≥30, KNN provided lower accuracy (79.6% each) and precision (79.0% and 68.7%), which were still higher than those of the other techniques. Conclusions The model derived from the KNN technique exhibited the best performance based on its highest level of accuracy. We demonstrate that this model is a useful tool for predicting OSA.
