PURPOSE: The purpose of this study was to identify the relationship of job stress, state of sleep, and depression and to identify factors influencing depression of emergency medical technicians. METHODS: The research was a cross-sectional, descriptive study. Data collection were done using self-report questionnaires with 162 emergency medical technicians working in hospitals who agreed to participate in the study. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation coefficients and multiple regression with the SPSS/WIN 18.0 Program. RESULTS: Depression had significant negative correlations with state of sleep, (r=-482, p<.001) and positive correlations with job stress (r=.196,p=.013). State of sleep had significant negative correlations with job stress (r=-.168, p=.033). The variance for life satisfaction was 23.7% (F=25.964, p<.001). Variable of state of sleep significantly predicted depression of emergency medical technicians. CONCLUSION: Considering these results, for emergency medical technicians' job stress, state of sleep, and depression, further studies are needed. Furthermore, there is a need to develop and implement new strategies to improve depression among emergency medical technicians.

Patients with atypical or incomplete Kawasaki disease are at same risk for development of coronary artery complications as typical Kawasaki disease. In this communication we report six patients with unusual presentation of Kawasaki disease complicated by coronary artery aneurysms, in whom correct diagnosis were not made in time for proper treatment. One of these patients died from massive myocardial ischemia due to giant aneurysms along the entire coronary artery system. These patients had either less than enough number of diagnostic criteria at initial presentation or diagnostic signs which occurred over an extended period of time, resulting in difficulty in diagnosis during the acute phase. As a result, none of these patients received intravenous gamma globulin treatment. Thus strict adherence to currently accepted criteria for diagnosis of Kawasaki disease may lead to failure to recognize atypical form of this illness with potential sequelae of myocardial ischemia or sudden death. We would like to emphasize from this experience that clinicians must be aware of the wide variations in clinical presentation of Kawasaki disease and take an aggressive approach in making correct diagnosis by obtaining early cardiac evaluation in order to initiate prompt treatment with intravenous gamma globulin.

Higenamine was isolated originally from Aconiti tuber from Aconitum species and recently Higenamine was synthesized. The purpose of this study is to investigate the adrenergic effect of Higenamine on rabbit cardiovascular system. Blood pressure, cardic output, systemic vascular resistance and heart rate were measured after intravenous injection of Higenamine(2-100microg/kg/min). The effects of Higenamine were compared with those of other sympathomimetic drugs. The changes in the cardiovascular systems after pretreatment with Propranolol, Atenolol and Hexamethonium were also studied. The following results were obtained. 1) Higenamine increased the cardic output and the heart rate and decreased the blood pressure and the systemic vascular resistance. Those changes were dose-dependent. The duration of action of Higenamine was 5 to 8 minutes. 2) The effects of Higenamine were similar to those of Isoproterenol. The amount of Higenamine was more than 100 times the required amount of Isoproterenol in order to obtain the same casdiovascular effects. 3) The effects of Higenamine were blocked by Propranolol, The increase of cardic output and heart rate were blocked by Hexamethonium. Higenamine has stimulating action on beta1 and beta2 receptors. But Higenamine is much less potent than Isoproterenol.

Rett syndrome is progressive neurodegenerative disorder in female patients, characterized by autistic behavior, mental retardation, loss of purposeful hand skills, stereotypic hand movement, breathing dysfunction, severely impaired language, ataxia, and seizure. The diagnosis of Rett syndrome is based on its characteristic clinical manifestation and course. The electroencephalographic (EEG) findings of Rett syndrome are nonspecific, but a progressive deterioration in the EEG, characterized by a slowing of background activity and spike sharp wave discharges, may be observed. We experienced one case of Rett syndrome in a 5 year old girl having mental retardation, loss of purposeful hand skills, stereotypic hand movements (clapping, washing, hand-to-mouth), breathing dysfunction (hyperventilation/apnea). Her EEG findings on Video-EEG monitoring are excessive slowing waves during awake state and frequent spike discharges from left or centrotemporal area during sleeping. We report a case of Rett syndrome with brief review of related literatures.

We performed clinical and virological studies on 79 children with hand, foot and mouth disease (HFMD) who had been admitted or visited to the department of Pediatrics, Asan Medical Center from February to August, 1990. The results were as follows; 1) There were total of 79 cases with hand, foot and mouth disease during this period. The aseptic meningitis was combined in 18 cases (22.8%). 2) The male-to-female ratio of HFMD was 2.03 to 1, but that of aseptic meningitis was 8 to 1. 3) Hand, foot and mouth disease occurred more frequently in under the age of 5 years, and the aseptic meningitis in under the age of 1 year. 4) Hand, foot and mouth disease and the aseptic meningitis occurred mostly in May and June. 5) In addition to the skin manifestations characteristic in hand, foot and mouth disease, some of the patients with aseptic meningitis had the following symptoms: change of consiousness, seizure, monoparesis in the upper extremity, paraparesis in the lower extremity. 6) The causative agent of hand, foot and mouth disease associated with the aseptic meningitis in Seoul in 1990 seemed to be enterovirus 71 according to the serologic study.
