Background: Primary spontaneous pneumothorax is commonly treated with chest tube insertion, which requires hospitalization. In this study, we evaluated the efficacy, costs, and benefits of a portable small-bore chest tube (Thoracic Egg; Sumitomo Bakelite Co. Ltd., Tokyo, Japan) compared with a conventional chest tube. Methods: We retrospectively analyzed all primary spontaneous pneumothorax patients who underwent treatment at Gangnam Severance Hospital between August 2014 and May 2018. Results: A total of 279 patients were divided into 2 groups: the conventional group (n=236) and the Thoracic Egg group (n=43). Of the 236 patients in the conventional group, 100 were excluded because they underwent surgery during the study period. The efficacy and cost were compared between the 2 groups. There was no statistically significant difference between the groups regarding recurrence (conventional group, 36 patients [26.5%]; Thoracic Egg group, 15 patients [29.4%]; p=0.287). However, the Egg group had statistically significantly lower mean medical expenses than the conventional group (433,413 Korean won and 522,146 Korean won, respectively; p<0.001). Conclusion: Although portable small-bore chest tubes may not be significantly more efficacious than conventional chest tubes, their use is significantly less expensive. We believe that the Thoracic Egg catheter could be a less costly alternative to conventional chest tube insertion.

The purpose of this study was to find more effective method through comparison of manual chest compression and chest compression using $AutoPulse^{TM}$ device in pre-hospital simulation cardiac arrest. In order to achieve the purpose of the study, ambulance workers did two different style CPR in pre-hospital simulation cardiac arrest. Data analyzed by T test and ANOVA. Findings of this study are as follows. Firstly, manual chest compression is more effective than chest compression using $AutoPulse^{TM}$ device on scene. Secondly, chest compression using $AutoPulse^{TM}$ device is more effective manual chest compression in ambulance and in elevator. In conclusion, these findings provide strong evidence for the importance of hands off time and stable CPR before hospital arrival in explaining patient's prognosis. Therefore, strategies to conduct precise hands off time and stable CPR are needed to improve patient's prognosis.

Purpose: This study aimed to compare the chest compression quality between compression-only cardiopulmonary resuscitation (CPR) and conventional CPR. Methods: This study involved 123 participants randomly assigned to either the chest compression-only CPR training and conventional CPR training. After training for 120 min, the participants performed CPR for 4 min and the CPR quality was evaluated. The primary outcome was evaluated as the mean compression depth, and the secondary outcome was calculated as the proportion of chest compressions with an appropriate depth among the total chest compressions. Results: The mean compression depth was more deeper in conventional CPR than in compression-only CPR (57mm vs. 53mm, p <.001). The proportion of appropriate chest compression depth was also more higher in conventional CPR (98.8% vs. 68.6%, p <.001). As compared with every minute over time for a total of 4 min, the mean compression depth and the proportion of appropriate chest compression depth were deeper and higher after 1 min in conventional CPR than in compression-only CPR. Conclusion: The results suggested that conventional CPR is a better method than compression-only CPR in terms of chest compression quality.

Purpose : The purpose of this study is to demonstrate the effectiveness of using a digital sensor device during CPR by analyzing the results from that chest compressions with a digital sensor device are applied to cardiac arrest patients. Methods : This study analyzed the results from the experiment that 42 people were selected randomly among Korean 119 rescuers, and they divided into the experimental group using a digital sensor device and the control group only using their hands, then they had been observed to conduct chest-compressions to mannequins for 10 minutes. Results : The results were found that compression depth in both the control and experimental group was gradually decreased over time, but the experimental group not only kept the depth but also maintained the speed of chest-compressions close to 100 times a minute. In addition, due to the use of the digital sensor device, the insufficient recoil ratio of chest-compressions was significantly reduced. Conclusion : The results show that conducting chest-compressions with a digital sensor device keeps the compression-death, maintains the speed of chest-compression properly and makes the insufficient relaxation ratio of chest-compressions reduce significantly.

Objective: This study was designed to analyze the utility of routine chest X-ray on Korean medicine hospital admission. Methods: The chest X-ray reports and medical records of 618 patients who were admitted to Daejeon Korean Medicine Hospital from May 1, 2021 to June 30, 2021 were retrospectively reviewed. Results: Of the 618 patients newly hospitalized from May 1, 2021 to June 30, 2021, 560 patients (excluding readmission) were analyzed. The mean age of 560 patients was 53.26±17.20 years. There were 52 patients with abnormal findings, and their mean age was 69.62±15.59 years. Many of these patients had chest symptoms and a history of chest disease. There was no case that showed a significant diagnostic result by chest X-ray examination. Conclusion: The diagnostic usefulness of routine chest X-rays in Korean medicine hospital admission is low. But this does not mean that there is no need to perform routine chest X-rays upon admission.

Objectives : Purpose of this study is to suggest a diagnostic definition of Chest bind(結胸) in GangpyeongShnghanlun 15 letters provision. Methods : Using The Etymology Dictionary of Chinese Characters, we interpreted the meaning of Chest bind(結胸) and symptoms on 134th provision of Shanghanlun. Results : The meaning of Chest bind is endurance of worries. Symptoms on 134th provision can be interpreted as follows. Worrywart person whose behavior is dilatory, who suffer from an inferiority complex, feel pressure on chest, feel heavy with worries, unstable, talkative, suffer from a feeling of anger, think himself as fallen into a trap, feel always nervous and is stubborn can be in a situation of Chest bind. Conclusions : Chest bind is one of the Names of disease in Shanghanlun. The Name of disease has its own meaning that can be used as diagnostic evidence. Further studies are needed to verify a hypothesis of diagnostic definition of Chest bind.

Background: Blunt chest trauma accounts for 90% of all chest traumas in Europe and the United States and this causes 20% of all trauma-related deaths. The major cause of morbidity and mortality after blunt chest trauma is undetected injuries. For this reason, chest computerized tomography has gained popularity for the evaluation of trauma, but it is expensive and it exposes patients to radiation. This study identified the clinical features associated with the diagnosic information obtained on a CT chest scan, as compared with a standard chest X-ray, for patients who sustained blunt trauma to the chest. This study also evaluated the role of a routine computed tomographic (CT) scan for these patients. The patients who had chest computed tomography done after the initial chest x-ray were analyzed separately for the presence of occult injuries. Material and Method: We studied 100 consecutive patients from November 2006 to July 2007: 74 patients after motor vehicle crashes and 26 patients after a fall from a height >2m. Simultaneous with the initial clinical evaluation, an anteroposterior chest radiograph and a helical chest CT scan were obtained for all the patients. The data extracted from the medical record included the vital signs, the interventions and the type and severity of injury (RTS). Result: Among the 100 cases, 79 patients showed at least more than one pathologic sign on their chest radiograph, and 21 patients had a normal chest radiograph. For 17 of the patients who had a normal chest X ray, the CT scan showed multiple injuries, which were pneumothorax, hemothorax, lung contusion, sternal fracture etc. This represents that a CT scan is statistically superior to a chest radiograph to diagnose the pathologic signs. But on the other hand, as for treatment, only 31 patients were diagnosed by CT scan and they were treated with chest tube insertion ect. 42 patients needed ony conservative management without invasive thoracosurgical treatment such as chest tube insertion or open thoracotomy. 27 patients were treated based on the diagnosis made by the chest radiograph and physical examination. Conclusion: Chest computerized tomography was significantly more effective than routine chest X-ray for detecting lung contusion, pneumothorax and mediastinal hematoma, as well as fractured ribs, scapula and, sternum. Although the occult findings increased, the number of patients who needed treatment was small. Therefore, we suggest making selective use of a CT scan to avoid its overuse in ERs.

Chest pain is classified into two major categories of cardiac chest pain and non-cardiac chest pain. Cardiac chest pain is caused by cardiovascular disease, for example, myocardial infarction, angina pectoris, valvular heart disease, cardiac enlargement or hypertrophy, dissecting aortic aneurysm, pericarditis, myocarditis, etc. When the chest pain is not attributed to heart disease, it is termed non-cardiac chest pain. Non-cardiac chest pain is caused by pulmonary, gastrointestinal, musculoskeletal disease, psychiatric factor, etc. In tills case, we treated a 54-year old female patient who was diagnosed with dilated cardiomyopathy and suspicious sick sinus syndrome. She complained of chest pain, exertional dyspnea, dizziness and headache. For treatment, we made use of Yugultangami(六鬱湯加味) and Daejobwan(大造丸). Before and after treatment, we measured Heart rate variability(HRV). In result, the clinical symptoms were improved and there was a significant increase in assessmeut by Heart rate variability(HRV). Tills result suggests that Yugultaugami aud Daejowhan have a good effect on cardiac chest pain.

The purpose of this study is to classify the types of men's back and chest through the criteria which represent the characteristic of men's back and chest. We have the following conclusions based on our sample size of 291 men's back and chest. The result of factor analysis concerned with men's back indicates that six factors are extracted and they are consist of 80.6% of total variance. We divide the shape of back into three categories: bent, protrusion of the scapula, and breadth. Each category is divided into subcategories. According to the frequency based on our data entries of 291 men's back, we introduce five new types of men's back. 83.8% of examined men's back belong to one of these five types: (i) 15.5% of protrudent and lordotic type; (ii) 6.5% of flat and lordotic type; (iii) 22.7% of protrudent and normal type; (iv) 34.4% of flat and normal type; (v) 4.8% of flat and bent type. The result of factor analysis related to with men's chest shows that six factors are extracted and they are consist of 76.0% of total variance. We divide the shape of chest into three categories: thickness, breadth, and protrusion of the breast. Each category is divided into subcategories. According to the frequency based on our data entries of 291 men's chest, we introduce four new types of men's chest. 65.0% of examined men's chest belong to one of these four types: (i) 7.2% of full and well-developed type; (ii) 24.1% of full and developed type; (iii) 25.8% of flat and developed type; (iv) 7.9% of flat and under-developed type. In order to consider the shape of the upper body as a whole, the back and the chest types should be corresponded.
