Clinical analysis were performed on 247 cases of thoracic trauma, those were admitted & treated at the department of thoracic & cardiovascular surgery,Hanyang University Hospital during the period from Jan,1989 to June,1992. Age distribution of those was from 2 to 80 years old & mean age was 38 years old. The ratio of male to female patient was 186:61 [3:1].This ratio revealed high incidence in male patient. The most common cause of trauma was traffic accident in this series.The modes of injury were as follows: traffic accident 124 cases[50.2%],fall down 52 cases[21.05%], stab wound 47 cases[19.03%] and gun-shut wound 1 case.Ellapse time from accident to admission were 141 cases [57.09%] under 6 hr.Rib fracture were observed in 159 cases[64.37%], hemo or pneumothorax were observed 134 cases[54.25%] of total cases and location distributed Right:Left:Both[74:112:37], in left predominant. Conservative,non-operative treatment were performed in 128 cases and operation[open thoracotomy] 32 cases.Mortality was 1.6%[4 cases] & most common cause of death were due to irreversible shock with brain edema. Conclusively, more evaluation & co-operation of other department were expected treatment & better prognosis.

Gastric cancer is common cancer generating about 20% incidence in Korea. But Oriental medical doctor (OMD) often can't measure therapy on gastric cancer positively because that the prognosis on it is not good. It is impossible the results on all of diseases not only gastric cancer always to have to be good. It is required to find out the causes of diseases and therapy method to conquest the diseases for the medical therapy. But because the results on medical therapy are not always good, it is necessary for the doctor who want to treat the diseases like gastric cancer having the prognosis to be death to protect himself, like as the legal system, a medical policy. And consequently, this protecting legal system lead the medical therapy principle or method on some special diseases to therapy completion on it. As a results of policy, medical therapy have to be developed. It is studied the literature referencing gastric cancer, experimental articles to insist the effects of Oriental medicine planet to gastric cancer and the clinical cases on gastric cancer to be treated as Oriental medicine therapy to have effects. Recently, there have been many other development in oriental medical therapy. This development can be grouped as two type. One type is clinical part and the other is experimental research part. Specially the experimental research and clinical research on gastric cancer in oriental medical therapy have been developed. So the present day is the time to make medical policy on liver cancer for OMD to measure oriental medical therapy and develop oriental medical theory. As a above results, we propose that the name of gastric cancer have to use in Korean medicine security clinical name (한방의료보험상병명) to make oriental medical policy.

Objective : This study is performed to compare older with younger groups about clinical characteristics and overall outcome of treatments for the intracranial aneurysms. Methods : We retrospectively investigated 633 patients with cerebral aneurysms who were admitted to our institute from January 2000 to May 2004. The authors divided the patients of cerebral aneurysm into two groups, one the third, fourth decades and the other eighth, ninth decades, analyzed clinical characteristics and overall outcome of treatments. Results : There were 57 patients [9.0%] under 39years old and 58 patients [9.2%] over 70. The female to male sex ratio was 0.5 : 1 in the younger group[YG] and 7.3 : 1 in the older group[OG], showing a female predominance with increasing age. In the YG, aneurysms were found in anterior communicating artery[A-com] [44.8%], middle cerebral artery [31.0%]. In the OG, aneurysm of posterior communicating artery [30.1%] was most common followed by that of A-com [26.9%]. More smokers and alcoholics were found in the YG. Older age was related to poor Hunt-Hess grade, Fisher's grade on admission, high incidence of unruptured aneurysms, and endovascular surgery. There was a higher prevalence of hypertension, intraventricular hematoma, hydrocephalus, and rebleeding in the preoperative state in the OG and postoperative complications including hydrocephalus, subdural fluid collection, and systemic complications. Overall outcome was poorer with advancing age [p=0.01]. Conclusion : The patients with aneurysms in the YG have distinct characteristics compared to those in the OG. Because of a good clinical grade on admission, a thin subarachnoid clot, and Low incidence of perioperative complications, the overall outcomes of the young patients were better than those of the old patients.

Objective : To investigate the incidence of corpus callosum injury (CCI) in patients with mild traumatic brain injury (TBI) using brain MRI. We also performed a review of the clinical characteristics associated with this injury. Methods : A total of 356 patients in the study were diagnosed with TBI, with 94 patients classified as having mild TBI. We included patients with mild TBI for further evaluation if they had normal findings via brain computed tomography (CT) scans and also underwent brain MRI in the acute phase following trauma. As assessed by brain MRI, CCI was defined as a high-signal lesion in T2 sagittal images and a corresponding low-signal lesion as determined by axial gradient echo (GRE) imaging. Based on these criteria, we divided patients into two groups for further analysis : Group I (TBI patients with CCI) and Group II (TBI patients without CCI). Results : A total of 56 patients were enrolled in this study (including 16 patients in Group I and 40 patients in Group II). Analysis of clinical symptoms revealed a significant difference in headache severity between groups. Over 50% of patients in Group I experienced prolonged neurological symptoms including dizziness and gait disturbance and were more common in Group I than Group II (dizziness : 37 and 12% in Groups I and II, respectively; gait disturbance : 12 and 0% in Groups I and II, respectively). Conclusion : The incidence of CCI in patients with mild TBI was approximately 29%. We suggest that brain MRI is a useful method to reveal the cause of persistent symptoms and predict clinical prognosis.

The incidence of degenerative valve disease also increasing with the increasing life expectancy of the elderly population. Rheumatic valve disease is decreasing gradually and the incidence of calcified degenerative aortic stenosis (AS) is growing. Echocardiography is a very important tool for evaluating the prognosis and treatment method as well as the time of operation and diagnosis of heart valve disease. When evaluating valvular heart disease, 2-dimensional echocardiography, which observes all heart valves in detail, should take precedence. Understanding the clinical findings of degenerative valve disease and performing precise echocardiography are extremely important. In addition, an assessment of the severity of aortic stenosis is necessary to determine the surgical indications. An assessment of the severity by echocardiography was explained with three cases of degenerative aortic stenosis. To perform echocardiography accurately, it is necessary to understand degenerative valve disease and its clinical findings accurately.

Since the successful introduction of all-trans-retinoic acid (ATRA) and its combination with anthracycline-containing chemotherapy, the prognosis for acute promyelocytic leukemia (APL) has markedly improved. With ATRA and anthracycline-based-chemotherapy, the complete remission rate is greater than 90%, and the long-term survival rate is 70-89%. Moreover, arsenic trioxide (ATO), which was introduced for APL treatment in 1994, resulted in excellent remission rates in relapsed patients with APL, and more recently, several clinical studies have been designed to explore its role in initial therapy either alone or in combination with ATRA. APL is a rare disease in children and is frequently associated with hyperleukocytosis, which is a marker for higher risk of relapse and an increased incidence of microgranular morphology. The frequency of occurrence of the promyelocytic leu-kemia/retinoic acid receptor-alpha (PML/$RAR{\alpha}$) isoforms bcr 2 and bcr 3 is higher in children than in adults. Although recent clinical studies have reported comparable long-term survival rates in patients with APL, therapy for APL in children is challenging because of the risk of early death and the potential long-term cardiac toxicity resulting from the need to use high doses of anthracyclines. Additional prospective, randomized, large clinical trials are needed to address several issues in pediatric APL and to possibly minimize or eliminate the need for chemotherapy by combining ATRA and ATO. In this review article, we discuss the molecular pathogenesis, diagnostic progress, and most recent therapeutic advances in the treatment of children with APL.

Carcinoid tumor is called as neuroendocrine tumor and is classified into neuroendocrine tumor Grade 1, neuroendocrine tumor Grade 2, and neuroendocrine carcinoma based on the differentiation of tumors. Recently, the incidence of rectal carcinoid tumor has been increasing probably due to the increased interest on screening colonoscopy and the advancement of endoscopic imaging technology. As the rectal carcinoid shows a wide range of clinical characteristics such as metastasis and long-term prognosis depending on the size and histologic features, it is a challenge to give a consistent diagnostic code in patients with the rectal carcinoid. If the rectal carcinoid tumor is less than 1 cm in size, it can be given as the code of definite malignancy or the code of uncertain malignant potential according to International Classification of Diseases for Oncology (ICD-O) by World Health Organization (WHO). Because patients get different amount of benefit from the insurance company based on different diagnostic codes, this inconsistent coding system has caused a significant confusion in the clinical practice. In 2019, WHO updated ICD-O and Statistics Korea subsequently changed Korean Standard Classification of Diseases (KCD) including the code of rectal carcinoid tumors. This review will summarize what has been changed in recent ICD-O and KCD system regarding the rectal carcinoid tumor and surmise its clinical implication.

Colorectal cancer is the third leading cancer worldwide. Although incidence and mortality of colorectal cancer are gradually decreasing in the US, patients with metastatic colorectal cancer have poor prognosis with an estimated 5-year survival rate of less than 10%. Over the past decade, advances in combination chemotherapy regimens for colorectal cancer have led to significant improvement in progression-free and overall survival. However, patients with metastatic disease gain little clinical benefit from conventional therapy, which is associated with grade 3~4 toxicity with negative effects on quality of life. In previous clinical studies, cell-based immunotherapy using dendritic cell vaccines and sentinel lymph node T cell therapy showed promising therapeutic results for metastatic colorectal cancer. In our preclinical and previous clinical studies, cytokine-induced killer (CIK) cells treatment for colorectal cancer showed favorable responses without toxicities. Here, we review current treatment options for colorectal cancer and summarize available clinical studies utilizing cell-based immunotherapy. Based on these studies, we recommend the use CIK cell therapy as a promising therapeutic strategy for patients with metastatic colorectal cancer.

Clinical studies were made on 79 cases with thalamic hemorrhage diagnosed by computed tomographic scan and only localized on the thalamic area, were admitted to the Kyung San University Taegu Oriental Medical Hospital from August 1990 to March 1994. The age and sex distribution, sites of hematoma, recurrence rate, incidence of hypertension, inducing factor, prodromal syndroms, symptoms and neurologic signs on admission, relationship between the hospital course and many factors affecting the prognosis such as age, side of hematoma, level of consciousness, volume of the hematoma. ventricular hemorrhage were analysed. The results were summarized as follows; 1. The most prevalent age group was above 60 years of age with 50-59 years, 70-79 years, 40-49 years and 80-89 years of age in the order of frequency. Male to female ratio was 1:1.55. 2. The ratio of left hematoma to the right was 1.32:1. The recurrence rate of cerebrovascular accident was 17.7% 3. The incidence of hypertension was 69.6% and inducing factors of thalamic hemorrhage in the order of frequency were physical work(29.1%), drinking or eating(13.9%), walking(12.7%) and rest(12.7%), The prodromal syndroms were numbness of extremities(5.1%), headache(2.5%), fatigue(2.5%), dizziness(1.3%), insomnia(1.3%), but prodromal syndrom was not found in 89.9% of thalamic hemorrhage. 4. The symptoms and neurologic signs on admission in the order of frequency were motor disturbance(98.7%), dysarthria(82.3%), positive Babinski sign(78.5%), headache(69.6%), dizziness(62.0%). hemisensory deficit(48.1%). nausea or vomiting(39.2%), absent or sluggish light reflex(35.4%), changes of consciousness (35.4%), dysphagia (20.3%), voiding difficulty.(13.9%), facial palsy(6.3%), aphasia(3.8%), seizure(38%), 6th N. palsy(3.8%) and small pupil(1.3%). 5. The rate of improvement was found almost equally in the 4th, 5th and 6th decades, but it was shown with dramatic decrease in the over 7th decades. The hospital course had no relationship with the side of hematoma but the level of consciousness had influence upon the prognosis. 6, The small hematoma had better outcome than large in the volume of hematoma under 15cc, but volume of the hematoma had no influence upon the prognosis because the rate of improvement was 75.0% in the volume of hematoma over 15cc. The hospital course had no relationship with ventricular hemorrhage.

Background: Stomach cancer is the fourth most common cancer and the second leading cause of death from cancer in the world. In Iran, this type of cancer has high rates of incidence and mortality. This study aimed to assess the survival rate of patients with stomach cancer and its determinants in Kurdistan, a province with one of the highest incidence rates of stomach cancer in the country. Materials and Methods: We studied a total of 202 patients with stomach cancer who were admitted to Tohid Hospital in Sanandaj from 2009 to 2013. Using Kaplan-Meier nonparametric methods the survival rate of patients was calculated in terms of different levels of age at diagnosis, gender, education, residential area, occupation, underweight, and clinical variables including tumor histology, site of tumor, disease stage, and type of treatment. In addition, we compared the survival rates using the log-rank test. Finally, Cox proportional hazards regression was applied using Stata 12 and R 3.1.0 software. The significance level was set at 0.05. Results: The mean age at diagnosis was $64.7{\pm}12.0$ years. The survival rate of patients with stomach cancer was 43.9% and 7% at the first and the fifth year after diagnosis, respectively. The results of log-rank test showed significant relationships between survival and age at diagnosis, education, disease stage, type of treatment, and degree of being underweight (P<0.05). Moreover, according to the results of Cox proportional hazards regression model, the variables of education, disease stage, and type of treatment were associated with patient survival (P<0.05). Conclusions: The survival rate of patients with stomach cancer is low and the prognosis is very poor. Given the poor prognosis of the patients, it is critical to find ways for early diagnosis and facilitating timely access to effective treatment methods.
