  • It is necessary to have a dummy that describes the anthropometry of a victim with accuracy. This study presents three scaled side impact dummies constructed for the use of MADYMO. They represent five, fifty and ninety-five percentile Korean males ranged from the age of 25 through 39. Thirty-five anthropometric data were used to scale input files required for MADYSCALE. Geometries, inertia, joints and other parameters for dummies were scaled based on the configurations of EuroSID-1. This study proposes the lateral impact response requirements for head, thorax and pelvis of Korean side impact dummies. A lateral drop impact test was conducted for the head at the height of 200 mm. Lateral pendulum impact tests were also carried out for thorax and pelvis at three specific impact velocities. All these test results were obtained from simulation based on MADYMO. All the procedures of the three tests followed the requirement of ISO/TR 9790.

  • An 8-year old castrated domestic long-hair cat was presented with a two week history of abdominal distension. Physical examination revealed a non-painful, fluctuant, palpable mass in the right craniodorsal abdomen, and unilaterally muffled heart sounds on the right thorax. Routine clinico-pathological values were unremarkable apart from mild azotemia with a concurrent urine specific gravity of 1.031, which reflect a degree of renal dysfunction. Radiographic and ultrasound examinations of the thorax revealed the cardiac enlargement to be due to the congenital peritoneo-pericardial diaphragmatic hernia with liver occupying the right half of the pericardial sac. There was also a mild gypertrophy of the heart. Radiography and ultrasonography of the abdomen showed the mass to be composed of a large fluid filled cystic structures surrounding the right and left kidneys, and the kidneys themselves were of increased echogenecity. A diagnosis of perinephric pseudocysts was made. The patient responded well to the surgical procedures. Perinephric pseudocysts and peritoneo-pericardial diaphragmatic hernia in the cat are rare, and a case is described and the literature is reviewed in this report.

  • Lymphoid hamartomas are a rare benign disease which can be easily treated by complete surgical excision. They developed most often in the thorax, and can be discovered usually on routine chest X-ray.p But some of them can also be found because of pressure symptoms or the presence of a palpable mass if outside the thorax. We experienced a case of the hyaline-vascular type of lymphoid hamartoma in the left hilum of a 29 year-old Korean male in March, 1979. He was well except intermittent cough and left chest discomfort of a year duration and was treated by resection of the left upper lobe including nodular tumor masses. The histological characteristics were an aggregation of lymphoid follicles composed of concentrically arranged mature lymphocytes with centrally placed thick walled arterioles showing endothelial proliferation and some of them were hyalinized. Between the follicles, there was extensive capillary proliferation and infiltration of numerous lymphocytes, scanty plasma cells and eosinophils.

  • 유척삭종(parachordoma)은 팔, 다리, 가슴에 주로 발생하며 천천히 자라는 저등급 악성 종양으로 알려져 있다. 대표적인 감별진단으로는 척삭종(chordoma), 뼈외 점액양 연골육종(extraskeletal myxoid chondrosarcoma) 등이 있으며, 조직학적 검사와 함께 면역조직화학적 검사가 감별진단에 도움이 된다. 저자는 우측 흉벽에 발생한 유척삭종을 광범위 절제 및 흉벽 재건술 후 16개월 동안 재발없이 추적 관찰한 1예를 경험하였기에 문헌고찰과 함께 보고하는 바이다.

  • The number of vehicle accidents related to the side impact has increased since 1990 in Korea, thus the side impact test has been performed as one of the major vehicle evaluations of the Korean New Car Assessment Program(KNCAP) in 2003. A total of 77 vehicles of eight different types(compact, small, semi-midsize, midsize, and large sedans and small, midsize, and large sports utility vehicles) were tested in side impact and side pole impact conditions. In this study, the head and thorax injury values(HICs and chest deflections) of the side impact tests performed between 2003 and 2013 were investigated in terms of vehicle type, test year, and test condition. The recent vehicles showed better safety performances(lower injury values) and similar injury patterns were obtained between side impact and pole side impact tests.

  • Domestic insurance claims were statistically investigated to analyze the elderly driver's accident patterns and injury types in side impact crashes. Medical treatment records and accident vehicle damage photos have been surveyed for 5,419 cases. The results of our statistical analysis showed that the thorax injury risk of the elderly drive group is 8.8 and 4.0 times higher than that of the young and middle age group respectively. Diagnosis showed that most thorax injuries were caused by rib fracture. The head injury risk of the elderly female driver group seemed to be higher than that of the younger female driver group, however, statistical test has not been conducted because of the lack of number of samples for elderly female accident.

  • Right-sided diaphragmatic rupture is less common and more difficult to diagnose than left-sided lesion. It is rarely combined with the herniation of the abdominal organs into the thorax. High level of suspicion is the key to early diagnosis, and a delay in diagnosis is implicated with a considerable risk of mortality and morbidity. We experienced a case of right-sided diaphragmatic rupture combined with complete avulsion of the right kidney and herniation of the liver into the thoracic cavity.

  • Surgeons recommend dissecting lymph nodes in the thorax, abdomen, and neck during surgery for esophageal cancer because of the possibility of metastasis to the lymph nodes in those areas through the lymphatic plexus of the esophageal submucosal layer. Extensive lymph node dissection is essential for accurate staging and is thought to improve survival. However, it can result in several complications, including chyle leakage, which refers to continuous lymphatic fluid leakage and can occur in the thorax, abdomen, and neck. Malnutrition, fluid imbalance, and immune compromise may result from chyle leakage, which can be potentially life-threatening if it persists. Therefore, various treatment methods, including conservative treatment, pharmacological treatment such as octreotide infusion, and interventions such as thoracic duct embolization and surgical thoracic duct ligation, have been applied. In this article, the risk factors, diagnosis, and treatment methods of chyle leakage after esophagectomy are reviewed.
