PURPOSE: The purpose of this study is to find out the differences of distal femur morphology between the anterior cruciate ligament (ACL)-injured and the non-ACL injured on an magnetic resonance imaging (MRI), and the difference of bone structure by gender. MATERIALS AND METHODS: MRI Measurements of notch width (NW), bicondylar width (BCW), medial condyle width (MCW), lateral condyle width (LCW), medial-to-lateral condyle ratio (M:L ratio), and notch entrance width (NE) were taken from 120 subjects with ACL injury and the other 106 subjects without ACL injury, by three independent observers, at two different times. The measured values from MRI figures between the ACL-injured and the non-ACL-injured were compared and analyzed, with consideration of the differences by gender. Both intra and inter-observer reliability were calculated. RESULTS: There were significant differences of NW, BCW, MCW, LCW and NE by gender (p<0.001). While NW and MCW in male group were different (p<0.001), NW, MCW, M:L ratio and NW index (NWI) in female group were significantly different (p<0.001) in the bone morphology between the ACL-injured and non-ACL-injured. The intra- and inter-observer reliability was satisfying. CONCLUSIONS: If necessary to take an MRI, female patients with small NWI and NW injury should be carefully treated because of possibility of ACL injuries.

PURPOSE: The aim of this study is to compare the clinical results and radiologic changes of closing-wedge high tibial osteotomy (CW HTO) and opening-wedge high tibial osteotomy (OW HTO). MATERIALS AND METHODS: Seventy five knees were treated with a CW HTO and 41 with an OW HTO. For each patient the hip-knee-ankle (H-K-A) axis was evaluated and the degree of the medial compartmental arthrosis was measured by Ahlback-type radiological classification. The function of the knee was evaluated by the Tegner activity score, the Lysholm knee scoring scale and the Western Ontario and McMaster University index. Lateral radiographs were taken to assess the patellar height and the posterior tibial inclination. RESULTS: In both groups significant improvement of the visual analogue scale and range of motion was achieved. The frontal plane H-K-A axis was corrected significantly from varus to the range of physiological valgus and the arthrosis of the medial compartment of the knee progressed gradually. The body mass index was significantly influential to the progression of arthrosis. The functions of the knee were improved significantly in all cases. In the closing-wedge group, the patella height was increased at the postoperative period, while it was decreased in the opening-wedge group. There was a tendency of a decrease of the tibial inclination in the CW HTO group and a statistically significant increase of the tibial inclination in the OW HTO group. Recurrence of varus occurred in sixteen cases. CONCLUSION: In both groups, improvement of the function of the knee was achieved, but there was no statistical difference. However, the opposite result was found in the patella height and the tibial inclination.

PURPOSE: This study was performed to determine the prognostic factors influencing relapse pattern, overall and disease-free survival in patients treated with postoperative radiotherapy for endometrial carcinoma. MATERIALS AND METHODS: The records of 54 patients with endometrial adenocarcinoma treated postoperative radiotherapy at Pusan National University Hospital between April 1992 and May 2003 were reviewed retrospectively. Median age of the patients was 55 (range 35~76). The distribution by surgical FIGO stages were 63.0% for 0Stage I, 14.8% for Stage II, 22.2% for Stage III. All patients received postoperative external radiotherapy up to 41.4~54 Gy (median: 50.4 Gy). Additional intravaginal brachytherapy was applied to 20 patients (37.0% of all). Median follow-up time was 35 months (5~115 months). Significant factors of this study: histologic grade, lymphovascular space invasion and myometrial invasion depth were scored (GLM score) and analyzed. Survival analysis was performed using Kaplan-Meier method. The log-rank test was used for univariate analysis and the Cox regression model for multivariate analysis. RESULTS: 5-year overall and disease-free survival rates were 87.7% and 87.1%, respectively. Prognostic factors related with overall and disease-free survival were histologic grade, lymphovascular space invasion and myometrial invasion according to the univariate analysis. According to the multivariate analysis, lymphovascular space invasion was associated with decreased disease-free survival. GLM score was a meaningful factor affecting overall and disease-free survival (p=0.0090, p=0.0073, respectively) and distant recurrence (p=0.0132), which was the sum of points of histologic grade, lymphovascular space invasion and myometrial invasion. Total failure rate was 11% with 6 patients. Relapse sites were 2 para-aortic lymph nodes, 2 lungs, a supraclavicular lymph node and a vagina. CONCLUSION: The prognosis in patients with endometrial carcinoma treated by postoperative radiotherapy was closely related with surgical histopathology. If further explorations confirm the system of prognostic factors in endometrial carcinoma, it will help us to predict the progression pattern and to manage.

An understanding of the knowledges, attitudes and perceptions of different populations is key for public health policy makers. Here, a survey was performed on knowledge, attitudes, and perceptions about malaria diagnosis, prevention, control, and treatment. The 407 survey participants included both uninfected inhabitants and patients from 2 cities (Gimpo- and Paju-si) of Northern Gyeonggi-do, known as high-risk areas for vivax malaria. We used community-based study design and non-probability sampling method using the primary data. Association between variables were tested using χ2-tests. In general, the information on malaria reported by the participants in this study was unsystematic and included inaccurate details. The knowledge of malaria symptoms, identified as headache, chills and fever, was high, but the surveyed community lacks knowledge of the specific medications used for malaria treatment, with a large number of respondents having no knowledge of any form of medication. Survey questions with high correct answer rates included questions about easy treatment of malaria in Korea, the high daytime activity of malaria-borne mosquitoes, and the infection risk posed by outdoor activities. However, a large portion of the respondents was unable to provide simple medical and biological information about the disease. This study aimed to comprehensively evaluate the knowledge, attitude, and practical behavior of the surveyed community with respect to malaria and the implications reported here could be applicable to other malaria endemic areas in Korea.

PURPOSE: The aim of this study was to evaluate the correlation between the 3-dimensional (D) notch volume and the 2D notch width and notch shape as measured on magnetic resonance imaging (MRI), between subjects with anterior cruciate ligament (ACL) injury and those without ACL injury. MATERIALS AND METHODS: Knee MRI images were taken from 72 subjects with ACL injury and 80 subjects without ACL injury (January 2007 to January 2012; Gyeongsang National University Hospital, Jinju, Korea). We measured 3D notch volume and 2D notch width and notch shape. The measured values from MRI figures between ACL-injured subjects and non-ACL-injured subjects were compared and analyzed. These measurements (notch width, notch ratio) were correlated to notch volume. Both intra-observer reliability and inter-observer reliability were calculated. RESULTS: Notch width differed significantly between ACL injured subjects and non-injured subjects (p<0.001), while no significant differences in notch volume and notch shape were observed between the groups (male: p=0.43, female: p=0.22). CONCLUSION: The results of this study might suggest that certain 2D measurements (notch width) of the notch could be better than notch volume for prediction of ACL rupture risk.

Traumatic lumbosacral spinal subdural hematoma due to anatomical and pathological causes is rare, compared to epidural hematoma. If the time of trauma cannot be determined, intracranial and intraspinal signal intensity according to lapse of time are not coincident, resulting in confusion in terms of differentiation. Fat suppression magnetic resonance image (MRI) and computed tomography (CT) are utilized for differentiation. The intention of this study is to report on a case where spinal subdural hematoma of unknown time of occurrence is differentiated from subdural lipoma by taking advantage of fat suppression MRI and CT in order to perform an early surgical decompression with auxiliary review of literature demonstrating good prognosis of the procedure.

AIMTo evaluate the plasma TGF-beta1 level in erectile dysfunction (ED) patients of various causes.

METHODSSixty-two patients with ED and 26 potent men were subjected to the study. Based on multidisciplinary work-ups, including medical history, physical examinations, blood tests with lipid profile and hormones, penile duplex Doppler ultrasonogram and neurophysiological tests, causes for ED were classified as psychogenic (n=15), neurogenic (n=16) and vasculogenic (n=31). The plasma TGF-beta1 level was measured by the ELISA method.

RESULTSThe plasma TGF-beta1 level was significantly increased in the ED group (6.7+/-4.9 ng/mL), compared to the control (4.0 +/-2.1 ng/mL) (P<0.01). In the ED groups, there was a significant increase in the vasculogenic group (9.0 +/-5.5 ng/mL), compared to the psychogenic (3.8 +/-1.8 ng/mL) and neurogenic groups (4.8+/-3.2 ng/mL) (P<0.01). Of the vascular risk factors, both the smoking (7.5 +/-4.7 ng/mL) and dyslipidemia groups (7.4+/-4.4 ng/mL) showed significantly increased plasma TGF-beta1 levels, compared to the non-smokers (5.5+/-2.8 ng/mL), and those without dyslipidemia (4.8+/-2.8 ng/mL) (P<0.05).

CONCLUSIONVascular risk factors are associated with an elevated plasma TGF-beta1 level, which may contribute to cavernous fibrosis and ED.
