Purpose: The committee on trauma of the american college of surgeons, in its manual resources for optimal care of the injured patients involved in falls from less than 20 feet need not be taken to trauma centers. Because triage criteria dictate less urgency for low-level falls, this classification scheme has demerits for early detection and treatment of serious problems in the emergency room. Methods: A prospective analysis was conducted of 182 patients treated for fall-related trauma from June 2003 to March 2004. Falls were classified as group A (<3 m), group B (${\geq}3m$, <6 m), and group C (${\geq}6m$). Collected data included the patient's age, gender, site and height of fall, surface fallen upon, body area of first impact, body regions of injuries, Glasgow Coma Scale (GCS), Revised Trauma Score (RTS), and Injury Severity Score (ISS). Results: The 182 patients were classified as group A (105) 57.7%, group B (61) 33.5%, and group C (16) 8.8%. There was a weak positive correlation between the height of fall and the patients' ISS in the three groups (p<0.001). There were significant differences in GCS (p=0.017), RTS (p=0.034), and ISS (p=0.007) between group A and B. In cases that the head was the initial impact area of the body, the GCS (p<0.001) and the RTS (p=0.002) were lower, but the ISS (p<0.001) was higher than it was for other type of injuries. Hard surfaces as an impact surface type, had an influence on the GCS (p<0.001) and the ISS (p=0.025). Conclusion: To simply categorize patients who fall over 6 meters as severely injured patients doesn't have much meaning, and though patients may have fallen less than 6 meters, they should be categorized by using the dynamics (impact surface type, initial body - impact area) of their fall.

One hundred sixty one patients with the carcinoma of uterine cervix received curative radiotherapy at the Department of Therapeutic Radiology, Seoul National University Hospital between December, 1979 and December, 1982. According to FIGO classification; stage $I_a 1(0.6\%)\;1_b\;8(5.0\%),\;II_a\;31(19.3\%),\;II_b\;66(41.0\%),\;III_a\;3(1.8\;%),\;III_b\;46(28.6\%)\;and\;IV_a\;6(3.7\;%)$. The proportion of early stage cancer is too small because most of them treated by surgery. External beam whole pelvic irradiation was done first with 10MV x-ray or Co-60 gamma ray upto 4,000 or 5,000 rad for early and advanced cases, followed by one or two courses of intracavitary radiation using Fletcher-Suit Applicator loading c Cs-137. Supplementary external radiation to pelvic side wall to bring dose to 6,000 or 6,500 rads, if there is parametrial involvement or positive pelvic lymph node. Of the 161 Patients, 49 Patients were lost to follow-up but only 22 patients were lost in disease free state. And so, 86.3 percent of the patients were followed to time of recurrence or to date. The results are as follows ; 1. Locoregional control rates according to stage is: stage I $100\%,\;II_a\;90.3\;%,\;II_b\;75.8\%,\;III_a\;66.7\%,\;III_b\;58.7\%\;and\;IV_a\;16.7\%$, respectively. 2. Persistent or recurrent disease were localized in pelvic cavity in 32 of 50 patients and 6 had distant metastasis only. 3. Rectal bleeding was the most common complication and appeared mostly between 6 and 24 months after radiotherapy. Most of them had transient minor bleeding and only 2 patients needed transfusion and 1 patient needed colostomy due to rectovaginal fistula. 4. The 3 year disease free survival rate is: stage I $100\%,\;II_a\;78.0\%,\;II_b\;60.6\%,\;III_a\;66.7\;III_b\;46.3\%\;and\;IN_a\;16.7\%$, respectively.

Background: Pilomatrixoma is a benign tumor that originates from the hair follicle matrix. It usually presents as a hard, slow growing, solitary mass that can be easily misdiagnosed as other skin masses. The aim of this study was to clinically analyze a case series of pilomatrixoma in pediatric patients from Korea. Methods: A total of 165 pediatric patients from 2011 to 2018 with a histological diagnosis of pilomatrixoma were included. A retrospective review was performed using the electronic medical records, including patient demographics, number and location of the mass, clinical and imaging presentation, and postoperative outcomes. Results: There were 61 male and 104 female patients with 152 solitary and 13 multiple pilomatrixomas. Among solitary pilomatrixomas, the lesion commonly occurred in the head and neck (84.2%), followed by upper limbs (11.2%), lower limbs (3.3%), and trunk (1.3%). The pilomatrixoma lesion presented as the following types based on our clinical classification: mass (56.02%), pigmentation (25.31%), mixed (12.65%), ulceration (4.82%), and keloid-like (1.2%). Ultrasonography showed a high positive predictive value (95.56%). There were no specific complications observed except for two cases of recurrence. Conclusion: Pilomatrixoma has various clinical feature presentations and commonly occurs in the head and neck. Ultrasonography is a helpful diagnostic tool. Surgical removal of the lesion is the main treatment method with a low recurrence rate.

Purpose: We investigated complications after laparoscopic sentinel basin dissection (SBD) for patients with gastric cancer who were enrolled in a quality control study, prior to the phase III trial of sentinel lymph node navigation surgery (SNNS). Materials and Methods: We analyzed prospective data from a Korean multicenter prerequisite quality control trial of laparoscopic SBD for gastric cancer and assessed procedure-related and surgical complications. All complications were classified according to the Clavien-Dindo Classification (CDC) system and were compared with the results of the previously published SNNS trial. Results: Among the 108 eligible patients who were enrolled in the quality control trial, 8 (7.4%) experienced complications during the early postoperative period. One patient with gastric resection-related duodenal stump leakage recovered after percutaneous drainage (grade IIIa in CDC). The other postoperative complications were mild and patients recovered with supportive care. No complications were directly related to the laparoscopic SBD procedure or tracer usage, and there were no mortalities. The laparoscopic SBD complication rates and patterns that were observed in this study were comparable to those of a previously reported trial. Conclusions: The results of our prospective, multicenter quality control trial demonstrate that laparoscopic SBD is a safe procedure during SNNS for gastric cancer.

Objectives : The aim of this study is to give a statistical basis for the characteristics of patients who received cooperative medical care after being referred from Western medical departments to the Department of Acupuncture and Moxibustion in a Korean medical hospital. Methods : The request records were searched for cooperative medical treatment at the Department of Acupuncture and Moxibustion in a Korean medical hospital between September 1st, 2011 and August 31, 2016, based on the Order Communication system(OCS). The records were reviewed and retrospectively analyzed according to the patient's general characteristics, the chief diagnosis code based on the 7th Korean standard classification of diseases(KCD-7) before and after the cooperative medical care in the Department of Acupuncture and Moxibustion, and the actual treatment measures which patients received as a result of the cooperative medical care. Results : Among the 2702 records, 1549 patients were included in the analysis. The male to female ratio was 1 : 1.17. Sexagenarians formed the highest age group and the number of patients whose age was over 50 was 1176(75.92 %). The surgery department requested the cooperative care from the department of Acupuncture and Moxibustion for the highest number of patients, 1194(77.08 %). When analysing specific medical departments, Neurosurgery, General Surgery, Neurology, Otorhinolaryngology, and Physical medicine and rehabilitation followed. The frequency of chief diagnosis code used before the cooperative medical care was in the order of I, C, G, S, and M code, from highest to lowest. The order of the codes after the cooperative medical care was the same. Acupuncture treatment was the most frequently-used measure after the cooperative medical care. Following were infrared, moxibustion, transfer, herbal acupuncture, cupping, electroacupuncture, and so on. Conclusion : This study provides a statistical basis for the demands placed on the Department of Acupunture and Moxibustion for cooperative medical care with the Western medical department. Based on the present condition of cooperative medical care, more preparation and effort is required for its activation.

Purpose: This study was designed for identification of the main clinicopathological features of cysts in the oral and maxillofacial regions. Methods: A retrospective observational study was conducted on 164 patients who had been diagnosed with cyst of the jaw, from the database of 168 histopathological diagnoses at the Department of Oral and Maxillofacial Surgery of Busan Paik Hospital at Inje University, from January 2009 to December 2011. The subjects were treated and the following variables were recorded: gender, age, clinical signs and symptoms, histopathological distribution, treatment methods, and complications. A descriptive analysis of the study variables was performed using a chi-square test. Results: Among the 164 patients, there were more male than female patients (male-female ratio: 1.7:1). The most predominant ages were the 20s and 40s. Among the classes of pathological cysts, radicular cysts and dentigerous cysts were the most common, with incidences of 56.0% and 35.1%. Thirty-six percent of the patients had no symptoms; and of those who had symptoms, the main signs and symptoms were swelling (24.4%) and pain (17.1%). The most frequent management method was the combination operation, such as enucleation with or without extraction and apicoectomy of the causative teeth. Of the 164 patients, 13 had complications; and one patient who had been treated with enucleation with apicoectomy had a recurrent cyst. Conclusion: Using a chi-square test, no significant differences in prevalence were observed in relation to gender according to age. Comparative analysis of radicular and dentigerous cysts showed a significant difference in their prevalence according to their anatomical location, however, no significant differences in were observed in their incidence rates according to age.

Purpose: This epidemiologic research was carried out to investigate the degree and aspects of symptoms of patients suffered from TMD using RDC/TMD. Subjects and Methods: Subjects were the patients who had visited to SNUBH dental clinic from Jan. 2005 to Dec. 2005, and total 117 patients were included (M: 22, F:95). The signs and symptoms of physical, psychological and behavioral factors were retrospectively evaluated by questionnaires in the RDC/TMD. The patients were examined through clinical and radiological method, and diagnosed by same investigator. They were divided into 3 groups such as osteoarthritis group (group 1), internal deragnement (group 2), myofascial pain dysfunction syndrome group (MPDS, group 3). In addition, in patient with complex diagnosis they were divided into subgroups in detail (ex. group 1+group 2). In the questionnaire, several items were selected to calculate the graded pain score (grade $0{\sim}IV$), depression and vegetative symptoms, nonspecific physical symptoms(pain items included) and nonspecific physical symptoms(pain items excluded) in each group. Results: As a result of classification by diagnostic criteria of this study, the patients were distributed to 45% of group 1, 47% of group 2, 8% of group 3 in this study. In younger patients (under 25-year old, n=40), group 2 was occupied 57% (n=23) and group 1 was 35%, group 3 was 8%, while group 1 was occupied 75% in elderly-patients (over 40-year old, n=28) in present study (group 2: 21%, group 3: 4%). In the analysis of depression and vegetative symptoms, majority of patients in Group 2 were included in 'normal', and in Group 3 it appeared to have larger proportion of 'moderate' & 'severe' than others. According to nonspecific physical symptoms, there have been tendencies of higher ratio of 'severe' in patients with MPDS. In graded pain score, more than half (58%) of subjects were included in grade 0 and low disability (Grade I and II), and 27% were revealed high disability (grade III, IV).

Purpose: This study was aimed at elucidating the pathogenesis of talar osteochondral lesion by analyzing the histopathological findings. Materials and Methods: Twenty specimens from 20 patients who underwent surgical treatment for talus osteochondral lesions were studied. Preoperative MRI images including T1, T2, and stir images were taken and cases were classified according to modification of the Anderson's classification. There were 5 cases of MRI group 1, 6 cases of group 2, 7 cases of group 3 and 2 cases of group 4. A full thickness osteochondral plug including the osteochondral lesion of the talus was harvested from each patient and reviewed histopathologic changes of osteochondral fragment using H-E staining. Mean diameter of specimens was 8.5 mm and mean depth was 10.3 mm. Pathologic changes of articular cartilage and subchondral bone were observed. Subchondral bone was divided into superficial, middle and deep zones according to depth. Cartilage formation, trabecular thickening and marrow fibrosis were observed in each zone. Results: There were detachment of the joint cartilage at the tidemark in 16 cases of 20 cases and the separated cartilages were almost necrotic on the histopathologic findings. Cartilage formation within subchondral bone was discovered beneath the tidemark in 12 cases. Trabeculae were increased and thickened in 17 cases. These pathologic changes were similar to fracture healing process and these findings were more conspicuous near the tidemark and showed transition to normal bone marrow tissue with depth. No correlation between the pathological progression and MRI stages was found. A large cyst shown on MRI's was microscopically turned out to be multiple micro-cysts accompanied by fibrovascular structure and newly formed cartilage tissue. Conclusion: The histopathologic findings of osteochondral lesions are detachment of overlying cartilage at the tidemark and subsequent changes of subchondral bone. Subchondral bone changes are summarized as cartilage formation, marrow fibrosis and trabecular thickening that mean healing process following repeated micro fractures of trabecular. These osteochondral lesions should have differed from osteochondral fractures.

Purpose: The authors evaluated the differences between K-wires and Cannulated screw, plate for fixing the proximal metatarsal chevron osteotomy of moderate and severe hallux valgus. Materials and Methods: There were 62 patients (79 feetz) who were moderate and severe degree hallux valgus according to the classification of Mann. They all got the proximal chevron osteotomy when correcting the deformity. We divided the patients into 4 groups, Two K-wire fixed group as A, one cannulated screw fixed group as B. Two cannulated screw fixed group as C, Plate fixed group as D, Group A were patients (26 feet) and Group B were patients z(9 feet), Group C were patients (31 feet) and Group D were patients (13 feet). Preoperative, postoperative and follow-up hallux valgus angle (HVA) and intermetatarsal angle (IMA) were measured for each patient. ANOVA test and Student t-test were done for statistical analysis. Results: Mean follow up period was 43.8 months (range: 12~82 months). Preoperative mean IMA was $16.4{\pm}3.5$, $17.7{\pm}11.3$, $17.3{\pm}5.9$ and $16.6{\pm}2.3$ degrees in respectively group A, B, C, D. Immediate postoperative mean IMA was $5.6{\pm}3.4$, $7.3{\pm}4.4$, $7.6{\pm}4.4$ and $6.7{\pm}2.8$ degrees in respectively group A, B, C, D. The final mean IMA was $8.9{\pm}4.5$, $15.2{\pm}7.5$, $10.3{\pm}4.4$ and D $7.7{\pm}3.5$ degrees in respectively group A, B, C, D. There were significant statistical increase in final mean IMA of group B and C (p<0.05). Conclusion: The IMA was significantly increased in the group which used one or two cannulated screw for fixation on follow up, therefore more caution should be needed when using one or two cannulated screw fixation technique after proximal chevron osteotomy.
