For the purpose of evaluating the effect of noise induced hearing loss on the blood pressure, a cross-sectional study was conducted in 481 manufacturing industrial workers in Pusan area consisted of 275 workers from noisier plant (over 90 dB(A), high exposed group) and 206 workers from less noisy plant (below 85 dB(A), low exposed group) from April to December in 1985. The summarized results were as follows; 1) The degree of hearing loss according to the audible frequency was most notable in 4,000 Hz. 2) The prevalence of hypertension was 14.8% in total examined subjects. And also in 40 dB(A) hearing lost workers, there was no significant difference between high exposed group as 15.5% and low exposed group as 15.8%. 3) In 3 models analyzed by multiple regression technique to obtain the complexed extents of risk factors related to the diasatolic blood pressure, especially model iIII which contain age, body mass index, smoking, alcohol and family history of hypertension, duration of work, noise exposure level and degree of hearing loss in high exposed group was most remarkable compared to the others. 4) The most potential predictor related to the diatolic pressure in high exposed group was the degree of hearing loss. And the next were body mass index, familial history of hypertension and age in order. But in the case of low exposed group, the potential predictors were body mass index, age and familial history of hypertension.

PURPOSE: For evaluation of the growth hormone and cortisol responses to insulin stimuli in children with short stature, the human growth hormone secretion and cortisol level was monitored 30 and 60 minutes after insulin infusion by intravenousely. METHODS: The inclusion criteria of children for this study were that the height was below 3 percentile compare with the same sex and age children, bone age was younger more than one year of chronologic age, and insulin and L-dopa induced growth hormone secretion was below 10ng/mL. There were 10 children compatible with this criteria(group A) and 11 children was selected for control group(group B). Serum concentration of growth hormone was determined just before intravenous infusion of 0.1U/kg insulin and then 30 and 60 minutes after insulin infusion. Serum level of cortisol was determined simultaneously with the growth hormone but skip the level of the 30 minutes after insulin infusion. Serum glucose level was monitored on every time sampling the blood for determined growth hormone and cortisol level. Serum level of growth hormone and cortisol were determined by radioimmunoassay. RESULTS :The serum glucose concentration were decrease to under 50% of baseline level on 30 minutes after insulin infusion in A and B group. The serum growth hormone level before insulin infusion was 2.5+/-1.78ng/mL and changed to 2.2+/-1.69 ng/mL on 60 minutes after insulin infusion in group A. In group B, the serum growth hormone level alteration before and on 60 minutes after insulin infusion was from 5.5+/-6.67ng/mL to 12.6+/-7.91ng/mL. The serum concentration of cortisol was changed from baseline level 10.7+/-7.10, 7.9+/-3.98microg/dL to 16.7+/-11.47, 26.1+/-3.59microg/ dL on 60 minutes after insulin infusion in group A and B respectively, but some cases in group A show a little increase in cortisol level. CONCLUSION: On the basis of this study, it is suggested that the deficiency of growth hormone secretion is related to cortisol concentration in peripheral blood. But for more detailed assessment of this association, follow up studies will be needed in more cases.

BACKGROUND: Whether the changes of risk factors (hypertension, diabetes mellitus, smoking, alcohol) can precipitate stroke remains unknown, and antecedent infection and psychologic stress are described insufficiently as predisposing risk factors for cerebral infarction. Therefore, we attempted to examine the roles of recent infection, psychologic stress, and the changes of risk factors as potential precipitants in each stroke subtypes. We also tested the temporal relationship between preceding exposure to coldness and stroke onset. METHODS: In this case-control study, 113 consecutive patients with acute cerebrovascular disease (38 small vessel disease, 43 large vessel disease, 11 cardiogenic infarction, 4 infarction of undetermined cause, and 17 intracerebral hemorrhage) and 23 control subjects were evaluated. Changes of the risk factors (and their management) were interviewed. A sign/symptom based questionnaire was used to characterize the prevalence of recent prior infection and exposure to coldness. Psychologic stress was measured with the use of Social Readjustment Rating Scale. RESULTS: The negative change of alcohol drinking was significantly higher in the stroke group. However, there was no significant difference between stroke and control groups in the changes of the other risk factors. The prevalence of previous (within 1 month) infection was significantly higher in the stroke group compared with control subjects (p=0.03). However, there were no significant differences among the stroke subtypes in the prevalence of infection(p=0.08). Upper respiratory tract infections constituted the most common type of infection. The exposure to coldness was significantly higher in the stroke group compared with control subjects (p=0.002). The level of stress within the prior 1 month/1 year was significantly higher in the stroke group than control group (p=0.01). CONCLUSION: Our data suggest that preceding infection, exposure to coldness, psychologic stress, and the negative change of alcohol drinking may be com.

Herein we report a 51-year-old male with angioimmunoblastic lymphadenopathy who had developed rnaculopapular eruptions after the administration of crystalline penicillin, acetylsalicylic acid and sulpyrine. Skin biopsy showed mild lyrnphohistiocytic infiltration and extravasated RBCs around the blood vessels in the upper dermis. He had run a progressively downhill course in spite of vigorous chemotherapy and ultimately died.

BACKGROUND: Tsutsugamushi disease, Leptospirosis, and Hemorrhagic fever with renal syndrome(HFRS) are an acute febrile illness of autumn-winter type which are characterized by fever, headache, myalgia in acute stage. We reported the clinical and laboratory characteristics of 49 cases under investigation far febrile illness in rural communities of Korea in order to differentiate the diagnosis among Tsutsugamushi disease, Leptospirosis, and HFRS. METHODS: This study was done retrospectively by investigation of patient's age, occupation, symptom, laboratory findings and chest X-ray findings of Tsutsugamushi disease, Leptospirosis, and HFRS. All patients was seen in our hospital between September and November in 1997 and 1998 consecutive year. RESULTS: The most characteristic symptoms and signs of Tsutsugamushi disease were eschar(90.1%), and skin rash(70%). The epidemiological and laboratory characteristics of Tsutsugamushi disease were age 40 or more, farmer(90.1%), s-GOT(serum glutamic oxaloacetic transaminase) and s-GPT(serum glutamic pyruvic transaminase) elevation. The most characteristic symptoms and signs of Leptospirosis were sputum and cough(75%). The epidemiological and laboratory characteristics of Leptospirosis were all farmers(100%), hyperbilirubinemia(1.67 mg/dl). The most characteristic symptoms and signs of HFRS were gastrointestinal disturbance(100%), flank pain(66.7%). The epidemiological and laboratory characteristics of HFRS were leukocytosis, thrombocytopenia, azotemia, proteinuria (91.6%), and hematuria (83.3%). CONCLUSION: As the clinical feature, presence of eschar and skin rash were suggestive of Tsutsugamushi disease. As the clinical feature, presence of cough and sputum and laboratory finding such as elevation of bilirubin level were suggestive of Leptospirosis. As the clinical feature, presence of gastrointestinal disturbance, flank pain and laboratory finding of thrombocytopenia, and renal dysfunction were suggestive of HFRS.

A modern development of ambulatory ECG monitoring gave great advances in the diagnosis and evaluation of various cardiac conditions. Fifteen cases of ischemic heart disease, 11 cases of nonischemic heart disease, 5 cases of noncardiac disease and 9 cases of normal healthy subjects were studied from January 1980 to July 1981 in national Medical Center, with the following results: 1) The heart rate was decreased during night time, with less decreasing tendency in patients with ischemic heart disease. 2) Among 30 cases, including 12 patients with ischemic heart disease, who didn't show arrhythmia on routine 12 lead ECG, 12 cases, including 6 patients with ischemic heart disease, showed arrhythmia on Holter monitoring. 3) Among 5 cases with ischemic heart disease who showed premature ventricular contraction on day time monitoring, 2 cases didn't show premature ventricular contraction on nigh time monitoring. 4) The S-T segment and T wave were changed during night time in 2 cases with ischemic heart disease and in 2 normal subjects. From these results, we could assert that Holter monioring or ambulatory ECG tracing would be a good method for diagnosis and evaluation of ischemic heart disease, and other cardiac conditions. Several another studies with this equipment have to be performed and would give more distinctive outcomes.
