OBJECTIVE: To evaluate the correlations between prostate volumes estimated by transabdominal, transrectal, and three-dimensional US and the factors affecting the differences. MATERIALS AND METHODS: The prostate volumes of 94 consecutive patients were measured by both transabdominal and transrectal US. Next, the prostate volumes of 58 other patients was measured by both transrectal and three-dimensional US. We evaluated the degree of correlation and mean difference in each comparison. We also analyzed possible factors affecting the differences, such as the experiences of examiners in transrectal US, bladder volume, and prostate volume. RESULTS: In the comparison of transabdominal and transrectal US methods, the mean difference was 8.4 +/- 10.5 mL and correlation coefficient (r) was 0.775 (p < 0.01). The experienced examiner for the transrectal US method had the highest correlation (r = 0.967) and the significantly smallest difference (5.4 +/- 3.9 mL) compared to the other examiners (the beginner and the trained; p < 0.05). Prostate volume measured by transrectal US showed a weak correlation with the difference (r = 0.360, p < 0.05). Bladder volume did not show significant correlation with the difference (r = -0.043, p > 0.05). The comparison between the transrectal and three-dimensional US methods revealed a mean difference of 3.7 +/- 3.4 mL and the correlation coefficient was 0.924 for the experienced examiner. Furthermore, no significant difference existed between examiners (p > 0.05). Prostate volume measured by transrectal US showed a positive correlation with the difference for the beginner only (r = 0.405, p < 0.05). CONCLUSION: In the prostate volume estimation by US, experience in transrectal US is important in the correlation with transabdominal US, but not with three-dimensional US. Also, less experienced examiners' assessment of the prostate volume can be affected by prostate volume itself.

Background: No gold standard exists for bone mineral density (BMD) measurement of the ankle. This study aimed to determine the correlation between bone density using Hounsfield units (HU) based on computed tomography (CT) and BMD using dual energy X-ray absorptiometry (DXA) as well as to evaluate the correlation between HU and clinical outcome of ankle fracture. Methods: Fifty-one patients aged ≥65 years who underwent surgical treatment for trimalleolus or bimalleolus ankle fractures were included. The HU were measured at the distal tibia metaphyseal region approximately 1 cm proximal to the plafond on the axial images of preoperative CT. BMD was measured using DXA within one year before the injury. The clinical outcome was evaluated according to the Foot and Ankle Outcome Score (FAOS). Results: Although the HU of an osteoporosis group was lower than that of a non-osteoporosis group, we observed no significant difference between the two groups. The mean HU significantly correlated with the lumbar and total lumbar spine BMD using DXA. Increased HU significantly correlated with improved clinical outcomes in three of five FAOS subscales: symptoms, pain, activity of daily living (ADL), and quality of life (QOL). In a linear regression analysis adjusted for age and body mass index, increased HU significantly correlated with improved clinical outcomes in three of five FAOS subscales: symptoms, pain, ADL, and QOL. Conclusions The correlations between bone density using HU and BMD and those between HU and the clinical outcome were confirmed in ankle fractures. The HU of preoperative CT might provide valuable information for predicting postoperative clinical outcomes.

OBJECTIVE: We wanted to assess the MR imaging findings of ovarian cystadenofibroma and cystadenocarcinofibroma, and we wanted to find clues for making the differential diagnosis between them. MATERIALS AND METHODS: The MR images of 12 pathologically proven cystadenofibromas and two cystadenocarcinofibromas were reviewed, with a focus on the internal architecture, signal intensity and enhancement. RESULTS: All the tumors appeared as multilocular cysts, except for a single unilocular cystic mass and a single solid mass. The previously reported characteristic MR findings of cystadenofibroma (a multilocular cystic mass with a T2-dark-signal-intensity solid component containing small cystic locules) were found in only 43% of the tumors (6/14). Diffuse or partial thickening of the cyst wall with T2-dark signal intensity without a definite solid component was as common as the previous reported findings (6/14). Two cystadenocarcinofibromas showed more prominent solid portions with higher T2-signal intensities and stronger enhancement than did the cystadenofibromas. CONCLUSION: Diffuse or partial thickening of the cyst wall with dark-signal-intensity in multilocular cystic masses may suggest ovarian cystadenofibroma, and this type of appearance may be as common as the previously reported characteristic appearance. A prominent solid component with a higher T2-signal intensity and strong enhancement are the typical findings of cystadenocarcinofibroma.

The hand is frequently affected area in high voltage electrical burn injury as an input or output sites. Therefore, proper treatment method should be applied in order to achive aesthetic and funtioning hand. To reconstruction of soft tissue defect in hand, a variety of treatment have been, but most are associated with drawbacks, such as limited range, limited application, long time surgery, 2nd stage surgery, large donor defect. The reverse dorsal digital and metacarpal island flaps use the dorsal skin of the digital or metacarpal areas, and they are based on the arterial branches anastomosing the volar and dorsal arterial networks. The series of 15 cases of reconstruction for soft tissue defect due to electrical burn in hand were reviewed. Most cases survived completely and we could gain satisfactory results. Advantages of these flaps are minimal defect in donor site, good reliability, short time and easy technique, versatile variation, usefulness in secondary reconstruction. In conclusion, our result suggested that the reverse dorsal digital and metacarpal artery island flap are very useful methods for reconstruction of soft tissue defect due to electrical burn in hand, functionally and aetheticallly.

Split-thickness skin graft is a frequent, necessary method of treatment in burn patients. After harvesting a split thickness skin graft, there is a variety of options in the post-operative management of the donor site created. Dressing materials provide an occlusive and wet environment and aids in superior wound healing. Of the commercially available dressing materials, Medifoam(R), Allevin(R) and Polymem(R) are the most commonly used materials during the early phases of epithelization. Medifoam-B(R) is a more absorbant dressing material compared to other dressing materials. Its swelling ratio is 1200% and it contains a layer of wound promoters and antibiotics. The purpose of this study is to compare medifoam-B(R), Allevyn(R) and Polymem(R) in the healing time, infection rate, absorption ratio and pain degree. This study is based on 30 patient who underwent split-thickness skin graft in Hanil General Hospital from March 2002 to July 2002. All skin grafts were harvested with an electric dermatome, with a thickness depth of 0.012 to 0.016 inches. Three divisions of each donor site was managed separately with each different materials through postoperative days 0 to 1. Absorption property, infection rate, pain degree, time to complete epithelization were assessed. Medifoam-B(R) performed superior to Allevyn(R), Polymem(R). In conclusion, We suggest Medifoam-B(R) as a useful alternative in the management of the split-thickness donor site wound in the early phases.

STUDY DESIGN: Retrospective study. OBJECTIVES: To evaluate how the timing of pedicle screw fixation (early or late) in pyogenic spondylitis relates to the period of hospitalization, duration of intravenous antibiotic use, and recurrence of infection and to confirm the efficacy of early pedicle screw fixation for pyogenic spondylitis. SUMMARY OF LITERATURE REVIEW: Intravenous antibiotics and surgery including debridement and fixation are used as a treatment option for pyogenic spondylitis. MATERIALS AND METHODS: We retrospectively reviewed 31 patients who underwent posterior decompression and pedicle screw fixation with intravenous antibiotic treatment for pyogenic spondylitis from November 2005 to February 2015. We divided the study group into an early fixation group, whose instrumentation was inserted no later than 15 days after antibiotic therapy, and a late fixation group for cases who underwent the procedure 15 days or more after antibiotic therapy. We compared the period of hospitalization and intravenous antibiotic treatment, the rate and period of the prescription of oral antibiotics, and the rate of recurrence or reoperation. RESULTS: The period of hospitalization and intravenous antibiotic treatment of the early fixation group (55 and 43.4 days) were significantly shorter than those of the late fixation group (85 and 67.1 days). The rate and period of the prescription of oral antibiotics were not significantly different between the two groups. There was no case of recurrence or reoperation in either group. CONCLUSIONS: Early fixation using pedicle screws for pyogenic spondylitis reduces the period of hospitalization and intravenous antibiotic treatment compared to late fixation.
