Purpose: Early diagnosis and treatment are essential features to save the kidney in patients with an acute renal infarction. To reduce the delay in diagnosis, the clinical features and treatments of an acute renal infarction were evaluated. Materials and Methods: The medical records of 19 patients (14 men and 5 women) diagnosed with an acute renal infarction were retrospectively analyzed. Symptoms, findings of a cardiologic evaluation, laboratory findings, presumptive diagnosis and treatments were evaluated. Results: All patients complained of flank or abdominal pain. Fifty-three percent of the patients had a history of cardiovascular disease and 37% had no history of specific illnesses. The level of serum LDH was markedly elevated in all patients that performed the test. Initially, only 4 patients were diagnosed as acute renal infarction. In the others, the presumptive diagnoses were urinary stone, acute abdomen, aortic dissection and so forth. Seven patients were managed with conservative care due to the delay in diagnosis or poor general condition. Nine patients were managed with systemic anticoagulation and 3 with intra-arterial thrombolytic therapy. Conclusions: An acute renal infarction must be considered as one of the presumptive diagnoses in patients presenting with flank or abdominal pain and a history of cardiovascular diseases. Prompt CT scanning and testing of the serum LDH level will help in the accurate and immediate diagnosis of an acute renal infarction.

BACKGROUND: A lots of fires were happened every years. And then, the many peoples have died because of foe. It is important to plane for initial field emergency management that the major cause of death and injury type is analysed by large scaled fire. METHOD: We have analysed the fire victims by large scaled fire from Jan. 1995 to Dec. 1995 in Korea. We analysed systemic factors, environmental factors, patient factors which was acquired from medical records and interviews with victims, victim's famaly, rescuer. RESULT: The total number of victims are 130 and the mortality rate is 61.5% (80 patients). The major injury and cause of death were inhalation injury and trauma. The injury type of fire victims are 19 cases of inhalation injury, 13 cases of laceration,5 cases of burn,5 cases of contusion,4 cases of blephaloconjunctivitis. In fire deaths, the 78 victims (97.5%) were death associated with the gas inhalation, and the only 2 fire deaths were due to trauma. This result of the cause of death was higher inhalation injury than previously reported literature because most fires of our study was happened at the closed-maze area. CONCLUSION: When the fee was happened at closed-maze area, many victims foiled to escape the space because of smoke, toxic inhalants from combustible interior decoration, and then were death.

BACKGROUND: The Sampung Collapse took place at 17:55 June 29, 1995. The rescue operation encountered 458 dead and 477 multiply traumatized patients and 464 non traumatized peoples. We wanted to present basic data for disaster planning for example of Sampung Collapse. METHODS: We made a survey of accident field immediately after accident and interviewed with victims, victim's famaly, and rescuer. We analysed the medical record and SCL-9 (Hopkins symptom check list 90R) which was checked several list with victims, victim's family and control group. RESULT: The mean RTS was 11.9 and the mean ISS was 4.3.96 long bone fractures occurred in 76 patients. 127 case of vertebral injury occurred in 63 patients. Total number of surgical operations were 237. There are also many crushing injury and acute post-traumatic stress diseases. CONCLUSION: There are many injury types which are crushing injury, vertebral injury, blunt trauma and acute PTSD(post traumatic stress diseases). Thus, The field management, especially field triage, is very important. And, the urgent patients were 72 patients, about 5% of total patients, witch needed intensive care in tirtiary hospital. Therefore, we need to plan out the expeditious proper management. and prevention of disaster propagation.

BACKGROUND: Atopic dermatitis (AD) is primarily influenced by environmental factors including exposure to pollutants and indoor allergens (particularly, house dust mites). Al-though house dust mite antigens are the most prevalent components of indoor allergens in Korea, cockroaches also can be considered to act as an important allergen. OBJECT: This study was done to evaluate the differences in three different atopic patch test (APT) techniques, and the relationship between APT and skin prick test, total IgE, and specific serum IgE level using cockroach allergen. Methods: We performed patch test in 57 patients with AD and 30 normal controls on clinically lesional and normal appearing skin with German cockroach (GC) allergens (extract, as is) in three different techniques (standard, scratch, DMSO). Reactions were evaluated after 48hours, and compared with the results of skin prick test, total and specific IgE levels. Detailed atopy history and severity scoring were taken. RESULTS: In the GC (whole body) prick test positive group, there was 1263.02 IU/ml of total IgE, and this amount was significantly higher than GC (whole body) prick test negative group who had 549.46 IU/ml (P<0.05). The positive reaction rate to whole body of American cock-roach (AC) was significantly higher in the patient group than control group (p<0.05), but the positive rate to whole body of GC was high, but not significantly high in the patient group (p=0.053). There were significant differences in positive patch test reactions to either Ext or As is between patient group and control group (p<0.05). The positive rate to As is was significantly higher than to Ext in either lesional skin or non-lesional skin in patient group (p<0.05). But there were no considerable differences in positive reactions to either Ext or As is between 3 different methods (standard, scratch, DMSO mix) in both lesional and non-lesional areas (p>0.05). There was no significant relationship between the positive reactions to patch test and prick test to Ext and As is antigen. The APT results showed no significant concordances with skin prick test and RAST for cockroach antigens. CONCLUSIONS: APT seems to be a different dimension of atopic skin inflammation and may pro-vide further diagnostic information in addition to a patient's history, skin prick test, and RAST results.

PURPOSE:To identify the main toxic gas released from salted radish in rice bran(Dan-Mu-Ji) and to introduce the radiological findings of the patient who was exposed to the gas. MATERIALS AND METHODS: Chest radiographs and CT scans of one survivor among three men who were exposed to the gas from Dan-Mu-Ji were reviewed. Gas obtained from the closed bottle containing Dan-Mu-Ji was analized by using the gas chromatography. RESULTS: The radiographic examinations of the survivor were suggestive of pulmonary edema with it's rapidly improving consolidations in both lung. The headspace gas within the bottle containing Dan-Mu-Ji was mainly composed with carbon dioxide, ethyl alcohol and hydrogen sulfide, of which hydrogen sulfide was considered the main toxic gas released. CONCLUSION: Under the anaerobic condition, Dan-Mu-Ji released toxic hydrogen sulfide. Inhalation of hydrogen sulfide might produce non-cardiogenic pulmonary edema.

Measurement of blood lead (PbB) and blood zinc protoporphyrin (ZPP) are most common biological indices to identify the individual at risk for excess or the health sequences by lead exposure. Because PbB is known most important and reliable index of lead exposure, PbB is often regarded as a gold standard to detect lead exposure. But in Korea PbB is a secondary test item of detailed health check-up with positive finding of screening test in most occasion. Our lead standard requires all lead workers to take annual heath-check twice a year for investigation of their health effect due to lead exposure. Blood ZPP is one of most important index to detect high lead absorption in lead workers as a screening test. Measurement of blood ZPP is known well to correlate with PbB in steady state of exposure in most lead workers and is often used as a primary screening test to detect high lead absorption of lead workers with the advantage of simplicity, easiness, portability and low cost. The current cut-off criteria of blood ZPP for further detailed health check-up is 100 ng/dl which is supposed to match the level of 40 ng/dl of PbB according to our standard. Authors tried to investigate the validity of current criteria of cut-off level(100 ng/dl) of blood ZPP and possible another better cut-off level of it to detect the lead workers whose PbB level over 40 ng/dl. The subjects in our study were 212 male workers in three small scale storage battery industries. Blood ZPP, PbB and hemoglobin(Hb) were selected as the indices of lead exposure. The results were as follows. 1. The mean of blood ZPP, PbB and Hb in lead workers were 79.5+/-46.7 ng/dl, 38.7+/-15.1 ng/dl, and 14.8+/-1.2 g/dl, respectively. There were significant differences in blood ZPP, PbB and Hb by industry(P<0.01). 2. The percents of lead workers whose blood ZPP were above 100 ng/dl in the group of work duration below 1, 1-4, 5-9 and above 10 years were 8.6%, 17.2%, 47.6%, and 50.0%, respectively. The percents of lead workers whose PbB were above 40 ng/dl in those were 31.4%, 40.4%, 71.4%, and 86.4%, respectively. 3. The percents of lead workers whose PbB were below 40 ng/dl, 40-59 ng/dl and above 60 ng/dl were 54.7%, 34.9% and 10.4%, respectively. Those of lead workers whose blood ZPP were below 100 ng/dl, 100-149 ng/dl and above 150 ng/dl were 79.2%, 13.7% and 7.1%, respectively. 4. Simple linear regression of PbB on blood ZPP was statistically significant(P<0.05) and as PbB was 40 ng/dl, blood ZPP was 82.1 ng/dl. 5. While the highest sensitivity and specificity of blood ZPP test to detect lead workers with PbB over 40 ng/dl were observed in the cut-off level of 50 ng/dl and 100 ng/dl of blood ZPP, respectively, the highest validity(sensitivity+specificity) of blood ZPP to detect lead workers with PbB over 40 ng/dl was observed in the cut-off level of around 70 ng/dl of blood ZPP. But even with optimal cut-off level of around 70 ng/dl of blood ZPP, still 25.0% of false negative and 20.7% false positive lead workers were found. As the result of this study, it was suggested that reconsideration of current blood ZPP cut-off of our lead standard from 100 ng/dl to somewhat lower level such as around 70 ng/dl and the inclusion of PbB measurement as a primary screening test for lead workers was highly recommended for the effective prevention of lead workers.

OBJECTIVES: This study was carried out to assess psychosocial distress of lead workers and to examine the relationship between lead exposure indices and psychosocial distress. METHODS: The study design was cross-sectional and research subjects were 234 lead workers in primary smelting industry. General characteristics, job characteristics and social support were obtained by self-administered questionnaire and history taking. Psychosocial distress was measured using PWI(Psychosocial Well-being Index), a 45-item self-administered instrument. Blood lead(PbB), zinc protoporphyrin(ZPP), -aminolevulinic acid in urine(ALAU) were selected as indicators of lead exposure. RESULTS: There was significant difference in PWI according to lead exposure level and job characteristics. The results of correlation analysis showed that PWI was significantly correlated with PbB(r=0.203, P=0.002). CONCLUSIONS: Our results supported the association between lead exposure and psychosocial distress. The inclusion of psychosocial distress measurement as a special health examination for lead workers was highly recommended for the effective health management.
