Odontogenic keratocysts (OKCs) are one of the most aggressive cysts in the oral and maxillofacial area because of their high recurrence rate and infiltrative behavior. In growing patients with OKCs, a radical treatment approach might cause numerous complications, including the disturbance of jaw growth and loss of the involved tooth. This case report describes successful comprehensive orthodontic treatment combined with marsupialization of the cyst in a young girl who exhibited an OKC with impacted teeth. The 10-year-old girl presented with an OKC extending from the mandibular symphysis through the left mandibular body, with ectopic impaction of the mandibular left canine and first premolar, as well as congenitally missing bilateral mandibular second premolars. Interestingly, spontaneous improvement of the positions of the ectopic impacted teeth, along with a reduction in the size of the cyst, occurred during marsupialization. The sequential use of removable and fixed appliances enabled orthodontic traction of the impacted teeth. The treatment outcome was stable at 2.5 years after the end of the treatment. We speculate that comprehensive orthodontic treatment combined with marsupialization can be an effective treatment strategy for patients with OKCs, especially when they are encountered in young, growing patients with impacted teeth.

PURPOSE: A nasolabial cyst is a rare non-odontogenic, soft-tissue, developmental cyst arising anywhere on the face inferior to the nasoalar region. It is thought to arise from either epithelial remnants trapped along the lines of fusion during the development of face or the remnants of the developing nasolacrimal duct. This study examines various features of nasolabial cysts with bony involvement to provide a basis for correct diagnosis and treatment. METHODS: Eight cases of nasolabial cyst treated in Soonchunhyang Hospital between March 2002 and July 2010 were examined in terms of their clinical features and radiological and histological findings. Seven patients underwent surgical excision of the cyst via an intraoral, sublabial approach. One underwent incision and drainage. RESULTS: Our eight patients were seven women and one man. The most frequent symptoms and signs were facial deformity and swelling of the nasolabial fold. Computed tomography(CT) showed a well-circumscribed cystic mass lateral to the pyriform aperture. Seven cases had erosive lesions on CT, and the intraoperative findings were consistent with a nasolabial cyst with a bony defect. Typical histopathological findings showed that these cysts were most frequently lined with respiratory epithelium with ciliated columnar cells and cuboid cells. No patient developed complications or recurrences. CONCLUSION: A nasolabial cyst is often unrecognized or confused with other intranasal masses, including fissural and odontogenic cysts, midface infections, or swelling in the nasolabial area. Therefore, a careful clinical and radiological evaluation should be preformed when considering the differential diagnosis. We present eight patients with nasolabial cysts treated via a gingivobuccal approach with excellent functional and cosmetic results.

BACKGROUND: Stress can be induced from minor daily life event, and it is widely accepted that this daily minor stress is better predictive factor for relationship between disease and stress. In a number of laboratory studies, investigator reported that perception of stress can be reduced by physical exercise. So in this study, we observed relationship between exercise and stress from minor daily life event, and tried to clarify the effect of exercise on daily stress. METHODS: Volunteer was recruited from health promotion center of one university hospital. and they were doing regular exercise in more than three days per week. Participants completed measures of daily stress inventory and amount of daily exercise for seven days. To compare the daily stress amount between exercise day and no exercise day, we used repeated measures analysis of variance. We used the Wilcoxon signed rank test to compare difference of stress in different sex and different trait anxiety group. RESULTS: There was significant difference in appraisal of daily stress between exercise days and no exercise days. The amount of daily stress was significantly reduced in continuous low level of anxiety group and male by exercise. CONCLUSION: Exercise is associated with a reduction of daily stress appraisal from minor life event. And there is different effect of exercise on daily minor stress in the different anxiety level group and different sex group.

PURPOSE: Heterotopic calcification is the abnormal deposition of calcium salts in tissues other than bone and enamel, and it occurs in the form of dystrophic calcification or metastatic calcification. This deposition can occur under many conditions, but in some rare cases, it may develop in burns and nonhealed scars. It is difficult to treat the combination of heterotopic calcification and ulceration in scar tissues by using conservative therapy and to determine the margin of excision in such cases. Our study proposes the use of intraoperative C-arm-guided mapping of lesions with heterotopic calcification, and adequate excision of ulcers in chronic scars where heterotopic calcification is also observed. METHODS: This study included 2 patients and was conducted from January 2010 to July 2010. The first patient was a 63-year-old woman who presented with atypical calcium deposits and chronic ulceration in the lower one-third region of the right leg. The second patient was a 38-year-old man who presented with a nonhealing ulcer that had developed on the right leg 3 months earlier he had a history of 40% scalding burns on the entire body. Surgery is the most reliable method for treating heterotopic calcification therefore, both patients were treated using intraoperative C-arm-guided marginal mapping of heterotopic calcification, followed by release of contracture, and eventually split-thickness skin grafting. RESULTS: Plain radiographs of the leg showed spotty radiopaque areas in the hard part of the scar well superficial to the underlying bones. Histopathological analysis revealed multiple foci of calcified deposits, increased fibrosis, and inflammation in the scar tissue. Surgery-related complications were not observed. CONCLUSION: C-arm guided excision of calcified scars and the release of contracture can cure nonhealing ulcers and may therefore prevent recalcification.

Truncus arteriosus is characterized by a single arterial vessel arising from the base of the heart and giving origin to the systemic, pulmonary and coronary circulation. To evaluate the incidence, types, and associated anomalies, 18cases of truncus arteriosus diagnosed by angiocardiography, were reviewed and were compared with other reports. Ten of them were confirmed by operation. The overall incidence of truncus arteriosus was 0.127%. Accordin to Collett and Edwards classification. Type I was encountered in 11cases(61%), type II in 4cases(22%), and type III in 3cases(17%), All the patients had subtruncal ventricular septal defects. Eight patients showed truncal valve regurgitation and valve stenosis was noted in one case. A right aortic arch was present in 9 cases. Associated anomalies were atrial septal defect(8cases), patent ductus arteriosus(3cases), coarctation of the aorta(2cases), isolation of the left subclavian artery(2 cases), and right aortic arch with an aberrant left subclavian artery(1case). Truncus arteriosus is an uncommon congenital cardio vascular malformation. In the group of cases which we encountered, type I was the most common anomaly. Frequently associated anomalies were right aortic arch, incompetent truncal valve and atrial septal defect.

PURPOSE: Novel influenza H1N1 A virus developed pandemic infection, and patients requiring hospitalization have rapidly increased because of severe clinical symptoms and signs. We describe the clinical features of hospitalized pediatric patients with novel influenza virus infection. METHODS: We reviewed the medical charts of 128 pediatric patients under the age of 16 who were hospitalized in Dongguk University Ilsan Hospital between September 2009 and February 2010. We compared the clinical features of the pneumonia and non-pneumonia groups of patients, and analyzed clinical difference according to M. pneumoniae coinfection and severity of pneumonia. RESULTS: The male to female sex ratio of the subjects was 2.2:1, and the average age was 6.2 years. Sixty-five patients (50.8%) had pneumonia and their average age was 6.7 years. Variables including duration of admission, total WBC counts, neutrophil percentage and CRP were significantly different between the 2 groups, however, the other variables were not. The number of patients diagnosed with severe pneumonia was 20 (30.8%). M. pneumoniae coinfection occurred in 24.6% of patients in the pneumonia group, however, it did not influence the severity of pneumonia. Underlying asthma was more significantly associated with severe pneumonia than with mild pneumonia. There was no death case. CONCLUSION: In this study, 2009 novel influenza infection was more prevalent in school-age boys. M. pneumoniae coinfection occurred frequently, however, it did not seem to influence disease severity. Patients with underlying asthma tend to develop severe pneumonia more frequently.

OBJECTIVE: Childhood trauma is recognized as an important risk factor in suicidal ideation, however it is not fully understood how the different types of childhood maltreatment influence suicidal ideation nor what variables mediate the relationship between childhood trauma and suicidal ideation. This study examined the path from childhood trauma to suicidal ideation, including potential mediators. METHODS: A sample of 211 healthy adults completed the Childhood Trauma Questionnaire (CTQ), Beck scale for Suicidal Ideation (BSI), Functional Social Support Questionnaire (FSSQ) and Hospital Anxiety and Depression Scale (HADS). Path analysis was used to investigate the relationship among study variables. RESULTS: Of the several types of childhood maltreatment we considered, only childhood sexual abuse directly predicted suicidal ideation (β=0.215, p=0.001). Childhood physical abuse (β=0.049, 95% confidence interval: 0.011–0.109) and childhood emotional abuse (β=0.042, 95% confidence interval: 0.001–0.107) indirectly predicted suicidal ideation through their association with anxiety. Childhood neglect indirectly predicted suicidal ideation through association with perceived social support (β=0.085, 95% confidence interval: 0.041–0.154). CONCLUSION: Our results confirmed that childhood sexual abuse is a strong predictor of suicidal ideation. Perceived social support mediated the relationship between suicidal ideation and neglect. Anxiety fully mediated the relationship between suicidal ideation and both physical abuse and emotional abuse. Interventions to reduce suicidal ideation among survivors of childhood trauma should focus on anxiety symptoms and attempt to increase their social support.

PURPOSE: To compare the effect of using fibrin glue or 10-0 nylon sutures on the clinical outcome of patients undergoing pterygium excision and conjunctival autografting. METHODS: We retrospectively reviewed the medical records of 52 eyes from 46 patients who underwent pterygium excision and conjunctival autografting and were followed up for more than 3 months. The operation duration, postoperative inflammation, complications, and recurrence rates were compared between groups of 20 patients (22 eyes) for whom fibrin glue was used (fibrin glue group) and 26 patients (30 eyes) for whom suturing was performed with 10-0 nylon (suture group) in pterygium excision and conjunctival autografting. RESULTS: The operation duration was 27.71 (5.22) minutes in the fibrin glue group and 43.30 (8.18) minutes in the suture group (p = 0.000). Seven days after the operation, the fibrin glue group showed milder conjunctival inflammation than the suture group (p = 0.000). Postoperative complications and corneal recurrence rates were not statistically different between the two groups. CONCLUSIONS: The use of fibrin glue in pterygium excision with conjunctival autografting is likely to be a more effective, safer procedure than suturing.

This study was conducted to evaluate the accuracy of the official death registry in rural area. The base data used for the study was 379 deaths registered during the period of 1993 and 1994 in 4 rural townships of Chonnam Province. The interview survey for cause-of-death was performed on the next of kin and/or neighbor. Additional medical informations were collected from hospitals and medical insurance associations for the purpose of verification. The underlying cause-of-death of 278 cases presumed by the survey was compared to the cause on official death registry. There was a prominent disagreement of cause-of-death between the survey data and the registry data(agreement rate: 38.9~44.6%%, according to disease classification method). These results may be caused by extremely low rates of physicians' certification, which were mostly confined to the poisoning and injury. Symptoms, signs, and ill defined conditions on death registry could be classified into circulatory disease(32.3%), neoplasm(21.2%), digestive disease(7.l%), injury and poisoning(7.l%) and so on. These results suggest that careful attention and verification be required on utilization of death registry data in rural area.
