Here, we report a case of artificial prosthesis of the knee joint combining with homogenous bone transplantation for the treatment of giant cell tumor of the right distal femur. At one year follow up, the patient complains almost no pain nor tenderness at operative site and ambulates with partial weight bearing with crutches. The X-ray finding shows satisfactory bony union with progressive bony remodelling.

PURPOSE: The purpose of this study was to investigate the relationship among family functioning, empathy and aggression by high school students. METHODS: This was a descriptive study. The survey participants were 467 high school students from M city. Data were collected from November 29 to December 7, 2012 and self-report questionnaires including a Family Adaptability Cohesion Evaluation Scale, Interpersonal Reactivity Indexes, and an Aggression Questionnaire. The collected data were analyzed by descriptive statistics, independent-samples t-test, ANOVA, stepwise multiple regression. RESULTS: The majority of the subjects were 2nd graders (42.0%) and female (57.2%). 59.7% of the subjects had religion, 84.8% were living together with parents. The mean ages of their fathers and mothers were 49.90+/-0.20 and 46.85+/-0.19 respectively. Aggression was found to have a statistically negative correlation with family functioning and empathy. Stepwise multiple regression analysis revealed that the most powerful predictor of aggression was empathic concern. Empathic concern, family cohesiveness, perspective taking, personal distress and gender accounted for 16.7% of the variances. CONCLUSION: It is necessary to provide aggressiveness reduction programs for high school students that consider their family functioning and empathy.

The purpose of this study was to compare the dento-skeletal characteristics between functional and skeletal anterior cross-bite patients. Twenty-eight functional anterior cross-bite patients and thirty-one skeletal anterior cross-bite patients were selected as a test and a control group. Mean ages of the test and the control group were 9.6+/-1.8 and 9.8+/-1.9, respectively. Lateral cephalograms were taken. Forty-nine cephalometric variables were measured and statistical analysis was performed to find the morphological differences between the groups. Statistically significant differences were found in the cephalometric variables of cranial deflection, maxillary depth, ANB, convexity, NPo-AB, APDI, Mx 1-SN, Mx 1-NA angle, Mx 1-NA, Md 1-NB angle and Md 1-NB. The test group showed more Class III growth potential, more protruded maxilla, lesser maxillo-mandibular difference, more uprighted and retruded maxillary central incisor, more labially tipped and protruded mandibular central incisor.

Heat disorders are not uncommon in the military society due to supposedly hard training to overcome the environmental conditions. Twenty-two soldiers with heat disorders were admitted to Chin Hae Naval Hospital June 1969 through July 1970. Hoping that our clinical studies on them contribute to a renewed understanding, the results are reported in summary as follows: 1) Heat disorders occurred with an overall incidence of 3.1 per cent during running in early summer. 2) Of the twenty-two patients, eight (37 per cent) had heat cramps, six (27 per cent) heat exhaustion, five(23 per cent) heat stroke, and three(13 per cent) had undetermined disorder. 3) Ten patients(45 per cent) were comatous, and this occurred most frequently(80 per cent) among those with heat stroke. 4) All patients were grouped into four according to their physical status on admission. Those with heat exhaustion mostly belonged to group I (good) or group II (fair). Those with heat stroke and heat cramps eomprised most of group III (poor) and group IV (grave). 5) Group I and II patients recovered within 12 hours; group III, within 12~24 hours; and group IV, required more than 24 hours of care. 6) One patient with heat stroke, graded V, expired with sudden hypothermia 15 hours following admission. Overall mortality of heat disorders was 4.5 per cent, and that of heat stroke 20 per cent. 7) The rest recovered uneventfully within 19 hours of average.

Purpose: This study examined the characteristics of meniscal injury occurring in various sports activities. Materials and Methods: One thousand and ninety cases who underwent arthroscopic surgery for meniscus tear from June 2011 to February 2022 were included. Patients aged 65 years and older and those with previous surgical history, combined ligament injuries, and combined cartilage lesions were excluded. A retrospective analysis was conducted using the magnetic resonance imaging findings, arthroscopic findings, and medical records to analyze the tear pattern, sex, age, body mass index (BMI), and timing of the damage. Results: Among the cases, sports-related injuries accounted for 273 cases, constituting 32.6% of the total. Of these, 196 cases (71.8%) were male, with an average age of 34.1±15.1 years. The average age was significantly lower, and more males were in the sports injury group than the non-sports injury group (p<0.05). Moreover, acute injuries were observed in 161 cases (59.0%), and injuries with clear traumatic history were present in 176 cases (64.5%), which were significantly higher than in the non-sports injury group (p<0.05). On the other hand, no significant difference in the BMI was observed between the two groups (p=0.810). In the sports injury group, medial meniscus tears exhibited a longitudinal tear in 13 cases (11.0%), which was higher than the non-sports injury group with nine cases (2.9%). Root tears were observed in 11 cases (9.3%) and 58 cases (18.9%) in the sports injury and non-sports injury group, respectively, showing a lower incidence (p=0.004). For lateral meniscus tears, complex tears were significantly higher in the sports injury group at 50 cases (28.6%) compared to 61 cases (19.3%) in the non-sports injury group (p=0.017). Conclusion The sports injury group showed a significant prevalence of acute injuries and cases with a clear history of trauma among young males. Regarding tear patterns, longitudinal tears were more common in the medial meniscus, while complex tears were more prevalent in the lateral meniscus. Understanding these injury characteristics will become even more important as the sports population grows.

PURPOSE: To evaluate the cysticidal effect of 5 kinds of commercially available contact lens disinfectants against 2 clinical isolates of Acanthamoeba. METHODS: Five kinds of commercially available contact lens disinfectants were soaked with cysts of Acanthamoeba ludgdunesis and castellanii at the concentration of 10(3), 10(4), and 10(5) cells/ml for 1 and 4 or 6 hours. Cysts which were not excysted in 7 days after treatment were recognized to be killed. Morphologic changes were evaluated by electron microscopic observation. RESULTS: Contact lens disinfectants which contain myristamidopropyl dimethylamine (MAPD) showed the best cysticidal effect. These disinfectants demonstrated a cysticidal effect on both Acanthamoeba species of all concentrations in 6-hour treatment. Contact lens disinfectants which contain polyhexamethylene biguanide (PHMB) did not demonstrate cysticidal effect, except for Acanthamoeba castellanii at the concentration of 10(3) cells/ml, in either 4- or 6-hour treatment. Separation of plasma membrane from endocyst and damage of organelles were prominent in cases showing a cysticidal effect. CONCLUSIONS: Contact lens disinfectant which contains MAPD may be helpful in preventing the Acanthamoeba keratitis. A higher concentration of PHMB is required to be effective in preventing Acanthamoeba keratitis.

Angiokeratoma of the vulva is a relatively rare, benign condition that usually presents as single or a few isolated papules mainly on the labia majora. It is histologically identical to angiokeratoma of the scrotum. A 50-year-old woman presented with a one year history of nonpruritic lesions on the vulva. Her skin lesions used to bleed vith subtle trauma. Several dark purplish papules, ranging in diameter from 3 to 5mm, were noticed on both labia majora. A biopsy confirmed the diagnosis of angiokeratoma. A simple electrodesiccation of all lesions was performed under local anesthesia. The patient has remained asymptomatic nd without recurrence for the follow-up period of 10 months without any recurrence.
