Secondary bone grafting in the alveolar cleft has proven effective in stabilizing the maxillary segments, providing continuity of the maxillary arch and facilitating the canine eruption into the proper position. The purpose of this study is to longitudinally evaluate the treatment results of secondary iliac bone grafting in 40 alveolar cleft patients with an observation period of more than 12 months. Interdental alveolar cleft height was measured in conventional dental radiographs taken no more than 1 month preoperatively, following the completion of all orthodontic expansion, using ratio of the adjacent tooth root and the narrowest point of cleft height. And then we measured the bone resorption rates in 1, 3, 6, and 12 postoperative months, respectively. There was significant positive correlation between presurgical alveolar cleft height and postoperative bone resorption rate. But there was not significant correlation between presurgical alveolar height and the age at operation. The overall success rate for achieving bony bridge across the cleft was 95%. The maximal bone resorption occured in 1 month after operation. In case that the secondary iliac bone graft was performed at the patient's pre-eruption stage of canine, 89% of the patient's canine erupted in 12 months after operation.

Uterine fibroids are the most common benign tumor of the female genital tract. Traditional therapy for symptomatic fibroids has been either myomectomy or hysterectony, depending on whether futhur fertility is desire. A promised new altermative therapy-embolization of the uterine arteries- is now available. A 29 year-old woman was diagnosed of uterine fibroid by ultrasonogram and other techniques. We have experienced one case of uterine fibroid necrosis after transarterial embolization. Now we report a case of uterine artery embolization for treattement of uterine fibriods with a brief review.

To foster humanistic physician, and to support medical students with the many adjustment problems which they commonly encounter in medical school, more personal and closer relationships between faculty members and students are warranted. This study was carried out to investigate faculties' and student's perceptions of the mentoring program in Gachon medical school. A total of 90 faculty members and 131 students responded to questionnaires. Most of the faculties and students believe this program to hold an important role in medical education. While majority of faculty members thought that the most important purpose of the program is to develop student attitudes by being a positive role model, most students perceived the development of personal relationships with faculties as being the most important. In addition, both faculty members and students listed an interest in education, as well as compassion for students as being important characteristics of a good mentor. With regard to perceived or anticipated problems of this program, many faculty members pointed to a lack of time and experience, while students indicated faculty members' passive attitudes and lack of interest in cultivating relationships with students. Findings from this study suggest several directions for improvement. First, to encourage active participation, students and faculties must understand the purpose of this program. Second, a training program to develop mentoring abilities should be provided for faculty. Third, a network among cooperating services should be introduced to keep this program running more effectively. Further, mentors and students should have regular meetings to promote closer relationships between them. This improved faculty mentoring program can serve as a continuing basis to facilitate personal and professional development of medical students.

PURPOSE: To clinically determine the proportion of people with a fixed dissociating eye in patients with dissociated vertical deviation (DVD). METHODS: Medical records of 86 patients diagnosed with DVD in our department of ophthalmology from 2001 to November 2011 were retrospectively analyzed. RESULTS: Of the 71 patients, 25 (35.21%) showed a higher degree of dissociation in the fixating eye, 26 (36.62%) had higher dissociation in the non-fixating eye; 20 of 25 patients with a higher level of dissociation in the fixating eye and 22 of 26 patients with a higher level of dissociation in the non-fixating eye received surgical correction for DVD, such as superior rectus muscle recession or inferior oblique muscle anterior transposition. CONCLUSIONS: In DVD, the proportion of patients showing a higher level of dissociation in the fixating eye was significant. Patients with DVD require thorough evaluation; measurement of the level of dissociation and determination of the fixating eye is beneficial for management and surgical intervention.

In order to investigate the potential cellular activity of remaind enamel epithelium of impacted tooth follicle, we have examined 75 tooth follicular tissues from impacted teeth by immunohistochemical methods. Particular focus on the proliferation, differentiation and apoptosis-antiapoptosis of remaind enamel epithelium was made. Follicular tissues were removed from impacted teeth, fixed in neutral formalin and prepared for 4micrometer thick 20 serial sections. Hematoxylin & eosin staining was done routinely, and the mucopolycharide materials of myxoid odontogenic mesenchyme was detected by histochemical reactions of toluidin blue, PAS, Van Gieson, Masson's trichrome Various antibodies, i.e., PCNA(proliferating cell nuclear antigen) and Ki-67 for proliferative activity, transglutaminase-C, transglutaminase-K, transglutaminase-E, TGF-beta1, bcl-2, and p53 were used. Apop-tag staining was also done to detect the phenomenon of apoptosis. Both of the reduced enamel epithelium in the luminal side of tooth follicle and the enamel epithelial rests scattered in the wall of tooth follicle showed frequent positive reaction for the PCNA and Ki-67, and these cells were also positive for the transglutaminase-C, K, E. On the other hand the enamel epithelium was not stained by Apop-tag staining but weakly positive for bcl-2 and p53. Relatively high amount of myxoid odontogenic mesenchyme was also diffusely observed in the tooth folliclular tissue, and the distribution of the myxoid odontogenic mesenchyme was closely related with the distribution of enamel epithelial rest infiltration. Taken together, these data may suggest that the remaind enamel epithelial cells are biologically acitive rather than the dormant state after the completion of tooth formation, and that the remaind enamel epithelium may has interaction with odontogenic mesenchyme and will not be degraded easily but may have a potential for the odontogenic tumors.
