A clinical analysis was performed on 97 cases of chest injuries experienced at Department of Thoracic and cardiovascular Surgery, Armed Forces Capital Hospital during 2 years period from 1986 to 1988. Of 97 patients of chest trauma, 39 cases were result from penetrating injuries whereas 58 cases were from non-penetrating injuries, and there were 77 cases of hemothorax and / or pneumothorax, 47 of rib fracture, 8 of foreign body, 6 scapular and clavicle fracture, 5 of diaphragmatic injuries, 4 of paraplegia. The majority of chest injuries were encounted in the age group between 21 and 30 years-old, mean age was 25.9 years-old and all cases were male except one. Gun-shot wound was the most common cause in the penetrating injuries and the majority of non-penetrating chest injury patients were traffic accident and fist or kick accounted for next. The principles of therapy for chest trauma were rapid expansion of the lung by closed thoracostomy[45 cases] and thoracentesis only[3 cases] but thoracotomy done at 27 cases because of massive bleeding or intrapleural hematoma, foreign body, cardiac injury, diaphragmatic injury and bronchial rupture. The over-all mortality was 2.07 percent[2 cases among all], a case was from penetrating injuries and another was from non-penetrating injuries.

We present four cases of aberrant carotid arteries manifesting as pharyngeal masses with throat discomfort. The symptoms of this anomaly are very similar to those of laryngopharyngeal reflux or globus pharyngeus. The identification of this anomalous artery is essential for the head and neck surgeon because the anomaly frequently manifests as a symptomatic pulsatile mass in the pharynx. All patients complained of foreign body sensation in the throat and showed protrusion of the posterolateral pharyngeal wall anteromedially. CT scans demonstrated that there were two cases involving the right common carotid artery (CCA) and two cases involving both CCAs in the retropharyngeal space. As conclusion, the aberrant course of the artery can occur on both sides of CCAs, and it can manifest as a pharyngeal mass. When the patients complain of foreign body sensation in the throat without any other abnormal findings in the pharynx, we should consider the possibility that it may be due to the aberrant course of the CCA and its bifurcations in the retropharyngeal space.

This study compared and analyzed with the United States(USA) to evaluated the level of readability of radiotherapy information (English text) provide to foreign patients with cancer by medical institutions in South Korea (KOR). A total of 20 the KOR and USA medical hospitals in 10 each provide information for radiation therapy technology were selected. The readability was comparatively analyzed a total of three aspects (lexical, syntactic, cohesion and readability) by using a Coh-Metrix on-line web program. In readability respect, the mean of the Flesch Reading Ease (FRE) was lower in the KOR (8.3) than in the USA (23.2), Flesch-Kincaid grade level (FKGL) was higher in the KOR than in the USA (14.2) indicating that KOR was less readable than the US (p<.05). In both KOR and USA, the reading level (literacy) of the English text for the radiation therapy was found to be higher than high school (FRE level 50 or lower). Therefore, text information in English for the radiation therapy to foreign patients with cancer should be lowered to elementary school level and read to improve the quality of medical services.

Purpose: Lawn trimmers are widely used to cut the weeds around graves in South Korea, but they can cause ocular injury. We investigate at the emergency room the incidence and the clinical features of ocular trauma induced by lawn trimmers. Methods:The authors analyzed 106 patients who visited Konyang University Hospital's emergency room from March 1, 2007, to October 31, 2011, because of ocular trauma caused by a lawn trimmer. Patients were sorted into two groups, severe ocular injury and mild ocular injury. Results: Over a 5-year period, 106 patients with ocular trauma caused by a lawn trimmer underwent clinical study. Most of the patient (103 patients) were males, and the average age of the patients was $51.75{\pm}11.66$ years. The incidence of ocular trauma peaked in the sixth decade of life. Most injuries occurred between July and September. Severe ocular injury developed in 46.2% of all patients. As age increased, so did the severity of the ocular injury. The impacting object was a small stone in 43.4% of all patients. Nobody wore protective gear. The most common diagnosis were corneal abrasion, followed by intraocular foreign body, corneal laceration, and sclera laceration. Fifty-four patients were followed up, and thirty-six patients of them had severe injury. The most common complication was a traumatic cataract. Conclusion: Ocular trauma induced by a lawn trimmer is more severe than general ocular trauma. We suggest that everyone using a lawn trimmer should wear protective gear and follow safety guidelines.

Foreign body aspiration (FBA) into the tracheobronchial tree could be life threatening requiringprompt intervention. Any objects placed in the oral cavity put patients at a risk of aspirating or swallowing the objects slipped or broken by physical injuries. Here, we report a case of 30 yr old patient with FBA during gold crown replacement was successfully treated with the use of the flexible bronchoscope. Case: A 30 yr old woman was admitted to Seoul National Dental Hospitalfor an amalgam restoration. She was scheduled to gold crown restoration for replacement of the damaged amalgam at #37 site. After performing crown lengthening procedure, the aspiration of gold crown occurred during the cementation of the crown. After aspiration, the patients complained of the subjective distress of respiration. Chest radiograph revealed that gold crown was enlodged to the left bronchus. Flexible fiberoptics was inserted to the bronchus to remove the aspirated crown. Fiberoptic assisted removal of the aspiratedcrown was successfully performed. After removal, there was no radiopaque material in the left bronchus on follow-up chest radiograph. Discussion: When aspiration of dental materials occurs, flexible fiberoptic can be used in the treatment of FBA. It is also very useful to take preventive management such as rubber dam, application of dental floss in dental procedure where there is high likelihood of FBA.

Purpose: Infection, foreign body reaction and decreased volume of implant are common complications after augmentation rhinoplasty with $Gore-tex^{(R)}$ implant. The author experienced two cases of recurrent foreign body granuloma in the patients who underwent $Gore-tex^{(R)}$ removal because of infection after augmentation rhinoplasty. and treated them with complete removal of$Gore-tex^{(R)}$. Methods: Case 1: A 49 year-old female visited our clinic for recurrent foreign body reaction on nasal dorsum and tip area. The patient underwent augmentation rhinoplasty with $Gore-tex^{(R)}$ 3 years ago and implant was removed due to infection 9 months ago. Excision of the granuloma was performed and a piece of foreign body suspicious to be a $Gore-tex^{(R)}$ implant debris was detected under the subcutaneous pocket. The implant fragments were removed and nasalis muscle rotation flap was performed to cover the lesion. The specimen was proved to be $Gore-tex^{(R)}$ in histological study. Case 2: A 31 year-old-male with recurrent foreign body granuloma on the nasal tip area visited our clinic. 10 years ago, the patient had augmentation rhinoplasty with silicone implant and then, he underwent revisional rhinoplasty five times including nasal implant removal, which was performed 9 months ago. The authors excised the granuloma and found a small sized foreign body suspicious to be a $Gore-tex^{(R)}$ implant debris under the granuloma. The foreign body was excised and identified to be $Gore-tex^{(R)}$ in histological study. Results: In both cases, the lesions were healed without any complications and there were no evidences of recurrence up to 6 months of follow-up. Conclusion: The $Gore-tex^{(R)}$ is known to be weak against mechanical force. These properties of $Gore-tex^{(R)}$ make it difficult to remove the implant completely. In the patient who have infection after augmentation rhinoplasty with $Gore-tex^{(R)}$, the operator should take care to perform the complete removal without remaining fragment of the implant.

Objectives: This study was conducted to evaluate the oral health literacy of foreign students in Korea regarding their utilization of dental clinic services and oral care products. Methods: This study measured the oral health literacy through a self-administered questionnaire that were distributed among 145 foreign students in Seoul and 153 Korean students in Wonju, Gangwon province. The questionnaire is used to assess the oral health literacy with a total of 92 questions including 30 questions on linguistic oral health literacy, and 40 questions on functional oral health literacy (sentence translation ability 27 questions, document decoding ability 13 questions), and 22 questions on the general characteristics. The collected data were analyzed by frequency test, ${\chi}^2$, independent t-test, and ANOVA with p-value of <0.05 was considered statistically significant. Results: The linguistic oral health literacy awareness score was doubly lower in foreign students $20.5{\pm}22.4%$ than Korean students $53.9{\pm}18.4%$ (p<0.05), three words were not statistically significant with less than 10% of all the foreign and Korean students. Correct answer rate of sentence translation ability was statistically significant in all questions by foreign students $26.7{\pm}27.1%$ and Korean students $99.0{\pm}2.3%$ (p<0.05). Correct answer rate of document decoding ability showed a relatively small difference between foreign students and Korean students with $54.7{\pm}33.1%$ and $87.3{\pm}8.7%$, respectively, but it was statistically significant in all questions (p<0.05). Oral health literacy according to residence period and Korean language class level of foreign students were the most correlated among the other variables (p<0.05). Conclusions: Dental terminology was difficult for ordinary people to understand regardless of the Korean language proficiency levels, so it is recommended and needed to express dental clinical terms in simple layman's term or to use illustrations to dental patients. In case of foreign residents in Korea, interpretation services are needed. Additionally, labels and instructions of oral hygiene products retailed in Korea with the consideration for foreigners are required.

Background and Purpose: To evaluate the blood flow velocity using doppler ultrasound of the carotid artery, vertebral artery, and basilar artery in stroke patients Material and Methods: To evaluate the blood flow, I measured the peak systolic velocity and mean velocity of the common carotid artery(CCA), internal carotid artery(ICA), external carotid artery (ECA). vertebral artery(VA), and basilar artery(BA) in 44 stroke patients and 15 healthy adults. To investigate the difference between ischemic stroke patients and normal healthy adults, I selected 44 ischemic stroke patients diagnosed by brain CT and brain MRI, and 15 healthy adults who did not have any symptoms of stroke, hypertension, heart disease, and diabetes melitus. Results: Peak velocity in normal adults was 50.6${\pm}$1.6cm/sec in the CCA, 67.2${\pm}$1.7cm/sec in the ICA, 62.5${\pm}$2.4cm/see in the ECA, 45.5${\pm}$1.9cm/sec VA. and 50.5${\pm}$3.5cm/sec in the BA. Mean velocity in normal adults was 26.9${\pm}$1.1cm/sec in the CCA, 43.7${\pm}$1.4cm/sec in the ICA, 26.7${\pm}$1.3cm/sec in the ECA. 31.6${\pm}$1.9cm/sec in the VA and 33.0${\pm}$2.6cm/sec in the BA. In this study, there was a significant increase in the velocity of ICA, ECA, and VA of ischemic stroke patients in comparison with normal healthy adults. And the blood flow velocity of this study in the CCA and ECA was different from other reported foreign values and the other known values in my country. Conclusion: There was a significant difference in the blood flow velocity between ischemic stroke patients and normal healthy adults. And the blood flow velocity of this study was different from other reported foreign values and the other known values in my country. Therefore, it needs more detailed studies about old aged Korean and ischemic stroke patients than previous studies.

관통성 손상 후 외부 이물질이 신체 조직 내 남아 있는 경우는 응급실을 방문하는 주요 원인 중의 하나이다. 수부에서 발견되는 이물질은 대부분 외상에 의해 발생하며 식물성 조각들이 가장 흔하고, 다음으로 유리조각, 금속조각의 순서로 발생한다. 특히 나무조각이나, 플라스틱 조각 등은 방사선투과성(radiolucency)을 가지고 있어 단순 방사선 사진으로 쉽게 발견하기 어려운 경우가 많아 외부 이물질을 찾는 것이 어려울 뿐만 아니라 일부 제거하더라도 이물질의 잔존 여부를 감별하기가 어렵다. 이에 저자들은 나무가시에 수상 당한 후 1차 의료기간에서 일부 나무가시를 제거 후 잔존 나무가시를 발견하지 못하고 수상 4주 이후 초음파을 이용하여 잔존 이물질을 진단하여 수술적으로 치료 후 동통의 감소를 보인 1례를 경험하였기에 문헌 고찰과 함께 보고하는 바이다.
