BACKGROUND: Job holders are groups that have suffered from chronic stressful condition. Nowadays, occupational stress are increasing due to Korean economic crisis. Therefore, this study was designed to evaluate the stress scores of several kinds of jobs, the relationship between the amount of stress and mental health status, factors associated with stress. METHODS: Among workers who had visited a medical college hospital, Taejeon, Korea, for regular health evaluation from April 1 to June 30 1998, we selected 50 clerks, 50 industrial workers, 50 professionals, 50 service or salesmen and 50 public servants in the survey. A total of 159 workers were evaluated as subjects excluding those who had answered in adequately to the questionnaire. Stress scores were measured by Korean-translated BEPSI(Brief Encounter Psychosocial Instrument) and Bae Jong Myun's 30-items SRRQ(Social Readjustment Rating Questionnaire). Mental health status were checked by Korean-translated SCL-90-R(Symptom checklist-90-Revision). RESULTS: The average BEPSI score of workers was 2.07+/-0.72. The mean score of female workers was 2.27+/-.70 and it was obviously higher than male worker's score of 1.85+/-.66. 20-29 year age group and over 40 year age group's amount of stress were obviously higher than 30-39 year age group. The low education level group had higher stress score than those with high education level but the amount of stress showed no significant difference in the monthly income, job tenure, number of family members to support, hobby and religion. According to occupation, clerks, industrial workers, service or salesmen's stress scores were higher than those of professional or public servants. CONCLUSIONS: This investigation has showed that there is a correlation between the amount of job holder's stress and mental health including somatimtian, obsessive-compulsive, interpersonal sensitivity, depression, anxiety, hostility, phobic anxiety, paranoid ideation and psychotism Therefore, we conclude that the best way to stay in good menta

BACKGROUND: The prognosis for children with relapsed acute lymphoblastic leukemia remains dismal. Ifosfamide has previously been shown to be active as a single agent and in combination with doxorubicin, etoposide, and teniposide in pediatric solid tumors, recurrent acute lymphoblastic leukemia and adult acute leukemia. We assessed the efficacy and the toxicity of the drug combination with ifosfamide and etoposide in patients with relapsed refractory acute lymphoblastic leukemia. METHODS: Between April 1995 and May 1996, twenty children aged 1 to 14 years with ALL in Catholic Medical Center, all heavily pretreated and in bone marrow relapse, were enrolled in this study. Drugs were given intravenously each day for 5 days at the following doses ; ifosfamide 1.8 g/m2/day, etoposide 100 mg/m2/day and mesna 1440 mg/ m2/day(as a uroprotectant) ; Cycles were repeated every 28 days for two cycles. RESULTS: 1) Twenty heavily pretreated patients were entered on study. At study entry, seventeen patients were in first relapse, two were in second relapse and one was in third relapse. 2) Six patients(30%) achieved complete remission, and eight patients(40%) achieved partial remission. Overall response rate was 70%. 3) Duration of remission ranged from 30 days to 230 days. 4) The toxicity of the regimen was tolerated. Moderate or severe toxicity evaluated on a per cycle basis included : neutropenia 52.5%, thrombocytopenia 45%, hemorrhagic cystitis 12.5% and mucositis 2.5%. 5) Two patients went on to bone marrow transplantation with histocompatibility matched sibling donors while in remission. CONCLUSION: The combination of ifosfamide and etoposide with mesna uroprotection has significant activity in relapsed refractory childhood lymphoblastic leukemia with tolerable toxicity. We recommended bone marrow transplantation after successful reinduction because of short remission duration of this regimen.

BACKGROUND: This study was carried out to evaluate the efficacy of desferrioxamine as a chelating agent in iron overloaded patients with severe aplastic anemia due to multiple transfusion. METHODS AND MATERIALS: From Oct. 1995 to Aug. 1996, 15 patients with aplastic anemia, diagnosed from May 1995 to Jan. 1996 at St. Mary's Hospital, who had a transfusional hemosiderosis were included in this study. They received 19 courses of high-dose desfer-rioxamine therapy for 6 days(20 to 30 mg/kg daily as a 24-hour intravenous infusion) . Before and after treatment, we measured serum ferritin, iron, TIBC, 24-hour urinary excretion of iron. RESULTS: 1) The range of iron load before treatment was between 4.5 and 20.0 gram. 2) Because of limit of detection(1,800 microgram/L), it was difficult to compare the changes of serum ferritin level after therapy to those of before therapy. 3) There was no significant differences between the levels of serum iron before and after therapy(214.3+/-62.8 vs 220.0+/-53.3). And there was no significant differences between TIBC before and after therapy(235.8+/-64.6 vs 259.4+/-60.1). 4) Iron/TIBC ratios were significantly deceased after desferrioxamine treatment compared to those of before therapy(0.90+/-0.04 vs 0.85+/-0.04, P<0.001) and mean urinary excretions of iron were increased by high-dose desferrioxamine compared to those by test dose(6.5+/-7.6 vs 29.1+/-14.3, P<0.001) CONCLUSION: High-dose desferrioxamine therapy is very effective for chelating and excretion of iron in iron overloaded patients with severe aplastic anemia due to multiple transfusion. A repeat administration of desferrioxamine is necessary for the iron overloaded patient to eliminate the risk of a transfusional hemosidersis.

We report a case of chronic bullous dermatosis of childhood occurring in a 8-year-old girl, who has multiple, pruritic, tense, vesicobullous eruptions on the both extremities and pelvic region without mucous membrane inuolvement. A skin biopsy revealed subepidermal vesicles infiltrated with many neutrophiles and a few eosinophiles. Direct immunofluorescent study of the perilesional skin demonstrated moderate intensity of linear IgA and to a lesser degree of IgG deposition at the dermoepidermal junction. The skin lesions responded dramatically to oral dapsone therapy, initially 4mg/kg, and taporing to 2mg/kg for 27 days.

PURPOSE: The purpose of this study was to describe the clinical characteristics of neonatal urinary tract infection (UTI) caused by Klebsiella pneumoniae and non- Klebsiella pneumoniae UTI. METHODS: We compared clinical characteristics of 84 neonatal patients with UTI caused by Klebsiella pneumoniae who were hospitalized at the Department of Pediatricsat Han Dong University, Sunlin Hospital during the period between May, 1994 and August, 1998. The cases were divided into two groups depending upon causative organisms' Klebsiella pneumoniae UTI vs non-Klebsiella pneumoniae UTI, and the clinical characteristics of these groups were compared. RESULTS: Escherichia coli was the most common bacterial pathogen causing neonatal UTI, followed by Klebsiella pneumoniae. There was no significant difference in the sex distribution of Klebsiella pneumoniae UTI, but non-Klebsiella pneumoniae UTI showed male predominence. There were no significant differences in the incidences of hematologic, urologic, radiologic findings and perinatal complications in between these 2 groups. CONCLUSION: Klebsiella pneumoniae is the second most common pathogen causing neonatal UTI. There were no specific differences in the laboratory, symptomatologic, and radiologic findings in these two groups.

In order to evaluate the confounding factors of neurobehavioral tests and the neurobehavioral effects in the workers exposed to organic solvents, NCTB was carried out on 100 workers. 46 workers had never been exposed to neurotoxic substances, and the others were being exposed to the solvents, mainly toluene. Simple reaction time, digit symbol, Santa Ana dexterity test and persuit aiming were different with age in non exposure group. Simple reaction time was carried out well in males, and digit symbol and persuit aiming were in females. There was no difference at educational level when the subject was educated over 12 years. Santa Ana dexterity and Benton visual test differed according to exposure level to toluene, however simple reaction time didn't. The acute neurotoxic effect was not excluded in this study. But, NCTB could be used to evaluate and prevent neurobehavioral changes in workers exposed to neurotoxic solvents in Korea.

PURPOSE: Fat embolism syndrome is caused by traumatic and nontraumatic conditions, and most commonly associated with fractures of long bones of the lower extremity. Clinical manifestation of the fat embolism syndrome occurs in a minority of patients with fat emboli. The incidence of fat emboilsm has been reported 5-10%. The pulmonary symptoms of fat embolism are clinically important but hard to diagnose, so treatment was often delayed. The purpose of this study is to search for the development of fat embolism after long bone fracture of rabbit, and to demonstrate pulmonary fat embolism by high resolution computerized tomograhy (HRCT) and pathologic findings. MATERIALS AND METHODS: Twelve rabbits (Newzealand, 2.5-3 Kg) were divided into 2, 24, 72 hours and control groups after closed tibiofibular fracture. The presence of involvement was classified by high resolution computerized tomography with ground glass opacity, consolidation and focal hyperlucency. The extent was measured by 10% grading scale. Gross inspection, histologic examination and histochemistry (Oil red 0) were performed in removed lungs. RESULTS: Ground glass opacity was found in 100% of test subjects, consolidation was found in 89%, bronchovascular bundle thickening was found in 78% and focal hyperlucency was found in 33%. Fat embolism was developed in all groups with the 24-hour group showing maximal changes. Microscopically the vessel was occluded with fat globule which was stained with Oil red 0 stain. CONCLUSIONS: The abnormal density lesion on HRCT was correlated with pathologic finding and was induced by fat emboli after long bone fracture of the rabbit

The purpose of this study was to analyse the center of resistance of the maxillary first molar using the 3-dimension finite element method. An extracted maxillary first molar of normal shape and average root length was selected and sectioned every 1.5mm parallel to the cementoenamel junction. Each section was traced and digitized to construct 3-D finite element model of the maxillary first molar. After a certain magnitude of counterbalancing moment(M) was applied to the tooth, a varying single force(F) of distomesial direction was applied to a certain point of the tooth until the tooth was translated. The force producing translation(Ft) was substituted to the equation deltad = M/Ft to calculate the center of resistance of the maxillary first molar. And reducing the alveolar bone level 1.68mm, and 3.36mm below to the cementoenamel junction, the tooth movement was analysed to see the effect of reducing the alveolar bone level to the location of the center of resistance. The results were as follows; 1. The center of resistance of the maxillary first molar was 3.72mm apical, 1.10mm buccal, and 0.71mm mesial to the geometric center of the horizontally sectioned surface at the cementoenamel junction. This point was 0.36mm apical, 1.20mm buccal, and 0.71mm mesial to the trifurcation point, indicating that it was not on the tooth root. 2. As the alveolar bone level was reduced, the center of resistance of the maxillary first molar was moved to the apical direction.
