Purpose: The aim of this study was to evaluate the clinical characteristics of classic heat stroke in Korea and to identify factors of prognosis for heat stroke by comparing a survival group with a non-survival group. Methods: We retrospectively analyzed 27 patients with heat stroke who visited the Emergency Department of Kyungpook National University Hospital from March 2001 to February 2005. First, we divided the patients into two groups, the classic heat stroke group and the exertional heat stroke group, and compared them. Second, we compared the survival group with the non-survival group. Age, sex, cause, place where patients were found, underlying diseases, cooling time, performance of endotracheal intubation, initial Glasgow Coma Scale, initial vital sign, and laboratory findings were reviewed. Results: Five of 27 patients in heat stroke died. The classic heat stroke group had 20 patients. They were old and had more patients in the bathroom than the exertional heat stroke group had. The non-survival group showed lower blood pressure, lower initial GCS score, and higher respiratory rate than the survival group. In laboratory findings, the non-survival group also showed lower$HCO_3-$ level, lower albumin level, lower glucose level, more prolonged PT, and higher CK-MB level than the survival group. Delay in recognition of heat stroke and cooling were poor prognostic factors in heat stroke. Conclusion: The classic heat stroke group had patients who were old and found in the bathroom. Early recognition and treatment of heat stroke is important to reduce mortality. Cooling time, initial GCS score, mean arterial pressure, resipratory rate, $HCO_3-$, PT, CK-MB, and albumin seem to be meaningful when forming a prognosis for heat stroke patients.

This study identifies Japanese study content on heat stroke prevention measures using clothes, provides basic data for quantitative wearing assessment studies, presents a developmental direction for those, and helps invigorate further research. Studies were collected concerning clothing-based heat stroke measures in order to analyze the following factors: current status of heat stroke by industry and working environment, heat stroke and body cooling method, clothing microclimate and air circulation in a hot environment, hot environments and wearable sensors, and heat stress reduction and skin exposure. The current WBGT standard does not consider the diversity of wearing clothes according to the working environment. Therefore, it is preferable to add a correction value in consideration of design, materials, and ventilation to prevent heat strokes. For the heat stroke and body cooling method, wearing water-perfused clothing is effective to reduce heat stress and maintain exercise ability. Changing the material and design of clothing or wearing air-conditioned clothing can improve ventilation and the clothing microclimate. However, further evaluation is needed on the effectiveness of air-conditioned clothing as a heat stroke prevention product. The measurement method using a wearable sensor can provide real-time data on the body response due to working in a hot environment. Therefore, it is an effective alarm for heat stroke. Skin exposure area and heat dissipation efficiency should be considered to prevent heat stroke. Reducing the covering area by exposing the head, neck, and limbs, and wearing breathable material can prevent heat stroke from increased body temperature.

Objective: The aim of this study was to evaluate the clinical characteristics of heat stroke in a bath facility and investigate predictive factors of multiple major complications in heat stroke patients. Methods: This was a retrospective study on heat stroke patients who visited an urban emergency center from January 2010 to March 2018. We compared clinical characteristics, complication, and outcomes of heat stroke patients in bath and non-bath facilities. Multivariate logistic regression analysis were performed to identify independent predictors of multiple major complications in heat stroke patients. Results: A total of 67 heat stroke patients with heat stroke were enrolled, of which 42 (62.6%) were in a bath facility and 25 (37.3%) were in a non-bath facility. Patients with heat stroke in the bath facility were characterized by old age, past medical history of hypertension and diabetes mellitus, and high incidence of hypotension compared with those in the non-bath facility but also low incidence of acute renal failure, seizure, and multiple major complications. In the multivariate analysis, predictive factors of multiple major complications in heat stroke patients were non-bath facility (odds ratio [OR], 5.4; 95% confidence interval [CI], 1.2-29.9), Glasgow Coma Scale (GCS)${\leq}8$ (OR, 8.2; 95% CI, 1.3-49.4), and mean arterial pressure (MAP), body temperature above $40.5^{\circ}C$ (OR, 8.1; 95% CI, 1.1-58.8) <60 mmHg (OR, 14.8; 95% CI, 1.8-122.9). Conclusion: Heat stroke in the bath facility resulted in less major complications, and high body temperature, GCS ${\leq}8$, and MAP <60 mmHg were independent predictive factors of multiple major complications in heat stroke patients.

Objectives: Changes in air temperature and its relation to ambulance transports due to heat stroke in all 47 prefectures, in Japan were evaluated. Methods: Data on air temperature were obtained from the Japanese Meteorological Agency. Data on ambulance transports due to heat stroke was directly obtained from the Fire and Disaster Management Agency, Japan. We also used the number of deaths due to heat stroke from the Ministry of Health, Labour and Welfare, Japan, and population data from the Ministry of Internal Affairs and Communications. Chronological changes in parameters of air temperature were analyzed. In addition, the relation between air temperature and ambulance transports due to heat stroke in August 2010 was also evaluated by using an ecological study. Results: Positive and significant changes in the parameters of air temperature that is, the mean air temperature, mean of the highest air temperature, and mean of the lowest air temperature were noted in all 47 prefectures. In addition, changes in air temperature were accelerated when adjusted for observation years. Ambulance transports due to heat stroke was significantly correlated with air temperature in the ecological study. The highest air temperature was significantly linked to ambulance transports due to heat stroke, especially in elderly subjects. Conclusions: Global warming was demonstrated in all 47 prefectures in Japan. In addition, the higher air temperature was closely associated with higher ambulance transports due to heat stroke in Japan.

Objectives : The aim of this study was to examine if there is a significant correlation between the changes of Fire- and Heat- related symptoms and motor function recovery in acute cerebral infarction patients. Methods : We studied inpatients within a month after the onset of cerebral infarction who were admitted at Kyunghee University Medical Center from May 2011 to January 2013. We executed correlation analysis between Fire-heat pattern score and motricity index score at visit 1 and visit 2, and checked if there was a significant correlation between the changes of Fire-heat pattern score and changes of motricity index score. Also, we compared the changes of both scores in patients taking Fire-heat and non Fire-heat pattern prescriptions. Results : There was a significant correlation between the Fire-heat pattern score and Motricity index score at visit 1 and visit 2, and changes of Fire-heat pattern score showed significant correlation with changes of motricity index score. Patients taking Fire-heat pattern prescriptions showed significant change in Fire-heat pattern score after herb-medication treatment while patients taking non-Fire-heat prescriptions showed insignificant change in Fire-heat pattern score. Conclusions : This study provides evidence that taking a Fire-heat pattern prescription could be considered as a first line herb-medication treatment in acute cerebral infarction patients.

The purpose of this study was to evaluate the diagnostic indicators which are used for the identification of fire-heat pattern in stroke patients. For evaluation of diagnostic indicator, we analyzed the indicators which are composed of symptoms and signs collected from stroke patients based on the clinical records using case report form (CRF). Patients had a first-ever stroke within 1 month after the onset of stroke. Pattern identification was performed and decided by two independent physicians. Two patient groups that consist of fire-heat pattern and the other patterns were compared to isolate important indicators affecting the fire-heat pattern identification of stroke patients. The 8 indicators among 16 fire-heat pattern indicators were significantly more frequent compared with non fire-heat pattern group. Logistic regression analysis revealed that 5 indicators among fire-heat indicators were significantly sensitive indicators being capable of identification of fire-heat pattern. But two of them was from the indicators of dampness-phlegm pattern and yin deficiency pattern. Therefore, further studies are required for the development of Korean standard indicators of Fire-heat pattern identification.

Heat stroke can lead multi-organ damage with hemorrhage and necrosis in the lungs, heart, liver, kidneys, brain and Ut. Heat stroke occurs when the elevation of core body temperatures induce a failure of thermoregulatory mechanism. A four-year-old male African Lion(Panthera leo) showed clinical signs such as panting, tachycardia, hyperthermia, unconsciousness and mydriasis under He hish humidity and hot weather. Clinical treatment and pouring cool water was unsuccessful. Grossly, congestion of lungs and pleura was observed. Yellowish discoloration was observed in the renal cortex. Microscopically, the coagulative necrosis in kidney and congestion of lungs and spleen were observed. In our knowledge, this case was closely associated with acute heat stroke.

Fire is known as one of the most common causes of stroke. Chest fever with dysphoria caused by heat in the stomach is one of the fire symptoms, meaning feeling oppressed in the chest. We observed two stroke patients who had chest fever with dysphoria. These patients' clinical symptoms were headache, thirst, heat in the upper part of the body and constipation. They were diagnosed as Chest fever with dysphoria. It is assumed that Exuberance of Yang causes heat. We treated them with Yangkyuksanhoa-tang(凉膈散火湯) based on Dong Ui Su Se Bo Won for about 2 weeks. During this period, we observed that their symptoms of heat in the upper part of the body and constipation had been improved. We suggest that Yangkyuksanhoa-tang makes the balance between water and fire, and improves chest fever with dysphoria of stroke patients.

Objective : Fire and heat related symptoms and signs are considered common in acute stage of diseases. The purpose of this study is to evaluate the occurrences and changes of fire and heat related symptoms and signs in acute cerebral infarction patients. Method & subjects : 40 acute cerebral infarction patients hospitalized in Oriental medicine hospital, Kyung-Hee University, who had examined and diagnosed 2 or 3 times based on oriental medical diagnosis were selected. We chose 23 as fire and heat related symptoms and signs from 94 diagnostic articles, and we added all those scores together of each patient. We analysed the scores of fire and heat related symptoms and signs as the time passed, and depending on oriental medical diagnosis. Result : In acute cerebral infarction patients of this study, 4 of fire and heat related symptoms and signs were took 1st, 2nd, 4th and 8th places in most changeable 10 articles of total 94 articles. The mean score of fire and heat related symptoms and signs of all patients were decreased significantly over the 3 times of measurements. The 8 patients diagnosed as fire and heat diagnosis at visit1 were samely diagnosed as fire and heat diagnosis at visit2, and at visit3 5 patients of them except for 3 patients excluded between visit2 and visit3, were still diagnosed as fire and heat diagnosis. At all of 3 measuring times, the scores of fire and heat related symptoms and signs of fire and heat diagnosis group were higher than non-fire and heat diagnosis group. Conclusion : This study indicated that fire and heat related symptoms and signs were very changeable phenomenon in acute cerebral infarction patients. And they decreased as time goes on.
