Lymphangiomas in the mediastinum are rare benign tumors, characterized proliferating lymphatic vessels. They are usually found in children and young adults, but rarely in order adults. Most are located in the neck, with less than 1 percent found in the mediastinum, with mediastinal lymphangiomas comprising 0.7-4.5 percent of all tumors in this location. They are often classified pathologically according to the size of the cystic spaces within them, as simple or capillary, cavernous and cystic, or just cystic, hygromas, Of the 3 types above, the cavernous type of mediastinal lymphangioma is very rare. We report a case of a mediastinal lymphangioma of the cavernous type that was confirmed from pathological findings, a CT and MRI scan.

Purpose: Trauma systems have been shown to decrease injury-related mortality. The present study aimed to compare the mortality rates of patients with major trauma (injury severity score >15) treated before and after the establishment of a level I trauma center. Methods: During this 20-month study, participants were divided into pre-trauma center and trauma center groups, and trauma and injury severity score (TRISS) method was used to compare mortality rates during 10-month periods before and after the establishment of the trauma center (October 2013 to July 2014 vs. October 2014 to July 2015). Results: Of the 541 total participants, 278 (51.5%) visited after the establishment of the trauma center. The Z and W statistics indicated better outcomes in the trauma center group than in the pre-trauma center group (Z statistic, 2.635 vs. -0.700; W statistic, 4.640). The trauma center group also exhibited meaningful reductions in the time interval from the emergency department (ED) visit to emergency surgery (118.0 minutes vs. 142.5 minutes, p=0.020) and the interval from the ED visit to intensive care unit admission (202.0 minutes vs. 259.0 minutes, p=0.035) relative to the pre-trauma center group. Conclusions: The TRISS and multivariate analysis revealed significant improvements in survival rates in the trauma center group, compared to the pre-trauma center group.

Delayed traumatic intracerebral hemorrhage (DT-ICH) is a rare event in head trauma patients. However, it develops unexpectedly and results in very severe brain damage. Thus, close monitoring of the neurologic status is needed for every trauma patient. Sometimes, however, neurologic monitoring cannot be done because of sedation, especially in cases of abdominal surgery. In this case report, we describe the case of a 37-yr-old, male patients who had hemoperitoneum because of spleen and renal injury. At the initial operation, massive bleeding was found, so gauze-packing surgery was done first. After the first operation, we sedated the patient for about two days, after which the packed gauze was removed, and the abdominal wound was closed. Immediately after the second operation, we found pupil dilation. Emergent CT was performed. The CT revealed DT-ICH with severe brain edema and midline shifting. However, the patient condition deteriorated progressively despite emergency operation, he expired 2 days after hematoma evacuation.

Blunt abdominal trauma may often cause multiple vascular injuries. However, common iliac artery injuries without associated bony injury are very rarely seen in trauma patients. In the present case, a 77-year-old male patient who had no medical history was admitted via the emergency room with blunt abdominal trauma caused by a forklift. At admission, the patient was in shock and had abdominal distension. On abdomino-pelvic computed tomography (CT), the patient was seen to have hemoperitoneum, right common iliac artery thrombosis and left common iliac artery rupture. During surgery, an additional injury to inferior vena cava was confirmed, and a primary repair of the inferior vena cava was successfully performed. However, the bleeding from the left common iliac artery could not be controlled, even with multiple sutures, so the left common iliac artery was ligated. Through an inguinal skin incision, the right common iliac artery thrombosis was removed with a Forgaty catheter and a femoral-to-femoral bypass graft was successfully performed. After the post-operative 13th day, on a follow-up CT angiography, the femoral-to-femoral bypass graft was seen to have good patency, but a right common iliac artery dissection was diagnosed. Thus, a right common iliac artery stent was inserted. Finally, the patient was discharged without complications.

Background: The purpose of this study was to compare the clinical outcome in patients aged less than 55 years who underwent arthroscopic tenodesis and arthroscopic repair for type 2 superior labrum anterior and posterior (SLAP) lesions. Methods: Between April 2008 and December 2014, surgery was performed on a total of 45 patients with isolated type 2 SLAP lesions. Arthroscopic repair was performed in 22 patients and arthroscopic tenodesis was performed in 23 patients. In both groups, the clinical outcomes at follow-ups were evaluated using the University of California at Los Angeles (UCLA) score, American Shoulder and Elbow Surgeons (ASES) score, and visual analogue scale (VAS) score. Results: In both groups, the VAS scores for pain had improved significantly throughout the postoperative follow-up period. The VAS score showed a statistically significant difference at postoperative 3 and 6 months (p<0.05); however, there was no statistically significant difference between preoperative and postoperative results at 12 months (p>0.05). In both groups, the functional outcome was statistically improved postoperatively. In a comparison of the UCLA and ASES scores between the two groups, there was a statistically significant difference at postoperative 3 and 6 months (p<0.05), but there was no statistically significant difference between preoperative and postoperative results at 12 months (p>0.05). Conclusions: Based on the results of this and other studies, patients with isolated type 2 SLAP lesions showed better short-term clinical outcome with tenodesis than with repair. However, there was no difference between the two groups at the final follow-up.

Objective : Alcoholic neuropathy is characterized by allodynia (a discomfort evoked by normally innocuous stimuli), hyperalgesia (an exaggerated pain in response to painful stimuli) and spontaneous burning pain. The aim of the present study is to investigate the effect of rolipram, a phosphodiesterase 4 inhibitor, against alcohol-induced neuropathy in rats. Methods : Allodynia was induced by administering 35% v/v ethanol (10 g/kg; oral gavage) to Spraue-Dawley rats for 8 weeks. Rolipram and saline (vehicle) were administered intraperitoneally. Mechanical allodynia was measured by using von Frey filaments. Somatosensory evoked potential (SEP) was proposed as complementary measure to assess the integrity of nerve pathway. Results : The ethanol-induced mechanical allodynia began to manifest from 3 week, and then peaked within 1 week. Beginning from 3 week, latency significantly started to increased in control group. In rolipram treated rats, the shorter latency was sustained until 8 weeks (p<0.05). The mechanical allodynia, which began to manifest on the 3 weeks, intraperitoneal injections of rolipram sustained statistical difference until 8 weeks, the final week of the study (p<0.05). Conclusion : This study suggests that rolipram might alleviate mechanical allodynia induced by alcohol in rats, which clearly has clinical implication.

The purpose of this study is that level of community members about dental hygienist's job of cognition and perception. The subjects of this survey were 500 of community members located in Gumi, Seoul, Incheon, Wonju.(response rate 92%) The results of study could be summarized as follows: 1. Women, 30 age group, officer and house keeper who had were experienced scaling higher level cognition of dental hygienist than another groups. 2. The group that had experienced oral examination, oral health consult, and the young group who had not experienced prosthodontic treatment had higher perception that dental hygienist main role is oral health care education. 3. The student who had experienced scaling had higher perception that dental hygienist's main role is oral disease prevention. 4. Over 30 age, women group who had experienced dental treatment between 6 month and 2 years had higher perception that dental hygienist main role is dental assistance At the conclusion of this investigation, We investigated that person's perception and cognition is promoted through scaling. Therefore we have to increase opportunity of oral health prevention and education role. In addition, we should notify dental hygienist with uniform, name tag and information about dental hygienist.

This study started with two questions. The first question is 'Why does organic agriculture want to be linked with cooperative?' The second is 'What is the characteristics of the mutual relationship between organic agriculture and cooperative?', especially in Wonju. Up to now, there have been various kinds of discussion about cooperation between organic agricultural campaign and cooperative in Wonju. But there are few concrete data showing what role cooperative plays in the cyclical process of production-distribution-consumption of organic agriculture. Thus, we conducted a survey applying the Delphi technique to the 35 organic agricultural specialists active in Wonju. First, small-scale family farm producers established a social economic cooperative network in around 2003 to perform 'the activities of innovators' through forming an organization. Producers moved from the stage in which they were supported one-sidedly by consumers to the stage where they could 'lead' cooperation. Each farm organization built a vertical integration, and horizontal cooperative systems with other farm organizations. But, practical cooperative activities have remained in the doldrums. They tend to show trends deviating from the principles of organic agriculture and cooperative. Second, the relationship between producers and consumers in Wonju can be described as 'producer-consumer cooperative type'. In Wonju, the producers' organization is not a sub-contractor which simply deliver organic agricultural products to producers' cooperative, but is an equal subject which creates its own value chain. The cooperative (cooperative organization) leads distribution and consumption of organic agricultural products and mutual communication. But, the closeness between producers and consumers has got loosened. And, it is problematic that the proportion of local food consumption in Wonju is very low. There is a very strong tendency to ride the central distribution system of producers' cooperative coalition. Consequently, it is necessary for producers' cooperatives in Wonju to run a local food distribution system based on the 'cooperative system among cooperatives'.

This study was designed to evaluate basic data about dental treatment under general anesthesia in pediatric dentistry of Wonju Severance Christian Hospital. Sex, Age, location, preoperative physical status, intubation methods, inhalation agents, duration of anesthesia and treatment, performed treatment and postoperative follow-up period and frequency were collected based on electronic medical records of 239 patients who visited pediatric dentistry at Wonju Severance Christian Hospital from March 2011 to February 2017. There were the most patients between the ages of 5 - 9, and there was no significant difference between male and female. The largest number of patients visited the hospital from Wonju, where the hospital was located. Most of preoperative status was ASA Class I. Orotracheal intubation was used in 169 of patients (70.7%). As an anesthesia maintenance agent, drug containing sevoflurane was used in 153 of patients (64.0%). In performed treatment, dental restoration, sealant and stainless steel crowns were performed 3.8, 1.8 and 1.1 times per person. 129 patients (54.0%) attended follow-up appointments under 6 months and those of the number of appointments were 1 - 4 times in average. General anesthesia as a behavior guidance in pediatric dentistry is increasing. Clinical guidelines for pediatric patients under general anesthesia are required through follow-up studies.
