To study the relationship between the bone mineral density measured by DEXA and QCT methods and to study the factors influencing on the value, bone mineral density in 208 patients with low back pain were measured by the two methods and compared statistically. Ages were varied between 17 to 79(Av. 46.7) years and male and female were 86 and 122. The results of this are as follows; 1. The values of DEXA and QCT showed statistically significant relationship(γ=0.58) as a whole. And bone mineral density in L2, L3 and L4 showed no difference in both groups. 2. Bone loss by aging(per year) in male and female was 0.99% and 1.06% by DEXA, 0,99% and 1.41% by QCT. 3. Body height and weight showed no significant influence of the value in two methods. 4. In body mass index over 27.5, the value measured by QCT was influenced to be diminished while that of DEXA was not influenced. 5. The value by QCT was influenced to be diminished by the increase of age especially over 50 years old in both sex. While the value by DEXA was influenced to be lowered than expected in female over 50 years old. It is concluded that the methods of measurement of bone mineral density have their limitation depend on the age, sex and mass index.

PURPOSE: To report the clinical data and visual outcomes after treatment of patients with dysthyroid optic neuropathy (DON). METHODS: We retrospectively reviewed the medical records and orbital images of 40 patients (65 eyes) with DON and analyzed the visual outcomes after treatment with intravenous steroids pulse therapy, radiotherapy and orbital decompression. RESULTS: The study included 21 men and 19 women, with 10 (25%) being diabetic patients. Visual field test results revealed defects in 88.7% of DON eyes; afferent pupillary defects in 63.2%; reduced color vision in 78.5%; and abnormal visual evoked potentials in 84%. Orbital imaging showed moderate to severe apical crowding in 95% of the orbits and intracranial fat prolapse in 24.2%. Median best corrected visual acuity improved from 0.4 to 1.0 after one year of treatment (p < 0.001). We noted more improvement in vision with the use of decompressive surgery than with non-surgical methods (p < 0.05). Recurrences occurred in 7 patients who had not received orbital radiotherapy. CONCLUSIONS: Visual field defects and apical crowding seen on orbital imaging were the most sensitive indicators for the detection of DON. Treatment with intravenous steroids pulse therapy, radiotherapy and orbital decompression effectively improved visual outcomes in cases of DON.

Osteochondromadevelop most commonly at distal femur, proximal humerus and proximal tibia, but the rib osteochondroma was reported less commonly. In this report, scapular snapping syndrome complicated by adventitious bursa and soft tissue pseudotumor surrounding the osteochondroma of the 6th rib body was treated successfully by surgical excision of them. We report this rare case with reviewing the relevant literature.

Pigmented lesions of palmar and plantar skin may cause diagnostic problems, because some features of benign lesions in these sites may raise the suspicion of melanoma if considered alone. Transepidermal elimlnation is a mechanism by which a substance is eliminated through the epidermis, and it is apt to be confused with a feature of melanoma that tumor cells are located at all layers of the epidermis. We report a case of transepidermal elimination of nevus cells in acral letiginous nevus which needs a differential dignosis of melanoma.

The diagnosis of soft tissue osteochondroma should be considered when a well-defined osseous mass is located in the soft tissues. The differential diagnosis includes myositis ossificans, tumoral calcinosis, synovial chondromatosis, and soft tissue osteosarcoma, true osteochondroma which arises from bone. One case of soft tissue osteochondroma in the knee, a lesion of uncertain pathogenesis is reported.

Spinal epidural hematoma is a rare complication of epidural anesthesia and most commonly associated with intraoperative or postoperative anticoagulant administration. We describe the case of an acute thoracolumbar epidural hematoma at the T12-L4 level complicated by cauda equina syndrome, which occurred after placement of spinal epidural catheter for anesthesia and anticoagulant therapy for acute myocardial infarction developed postoperatively. In our experience, the spinal epidural catheterization and anticoagulant therapy may potentially increase the risk of epidural hematoma formation.

BACKGROUND: Do-Not-Resuscitate(DNR) order has been used without specific legislation commonly in hospitals of Korea. We designed this study to assess the current use of DNR order in the emergency department and to make a database for establishing a policy for DNR order, especially in ER. METHODS: We retrospectively reviewed medical records of 164 patients who expired in the emergency department of Severance hospital from Sep. 1996 to Aug. 1997. We evaluated age, sex, diagnosis, specific department involved, whether written orders were made and medical care after decision of DNR. The patients were divided into 2 groups : DNR vs CPR. To determine factors influencing DNR decision, we searched for presence of malignancy, irreversible shock, unconsciousness and chronic illness. The logistic regression analysis was used for statistical significance. RESULTS: We found that 102(62.2%) out of 164 expired patients had a DNR order. But only in 59% of cases, were written DNR order on the chart. Factors which had the most influence on decision of DNR were malignancy and age. The sex, chronic illness, irreversible shock, and unconsciousness were not significant factors. CONCLUSION: We found malignancy and old age as an important factor when DNR order had been made. But further evaluation of other factors may be necessary to establish definitely a policy for DNR order.

For cervical cancer, the combination chemotherapy could increase the trial of radical hysterectomy due to reduction in tumor volume even in advanced stage and help to decrease corrected dose of radiotherapy. It also reduces postoperative radiotherapy to avoid the side effect and therefore make the quality of life better. Cisplatin chemotherapy alone was known to result in objective response rates of 20%. Todays animal experiment studies stated that Ifosfamide could accelerate the efficacy of Cisplatin. Thus in this study, neoadjuvant chemotherapy was applied to those cervical cancer patients in the use of the combination chemotherapy including Ifosfamide, PI(Cisplatin+ Ifosfamide) and PAIB(Cisplatin+ Ifosfamide+ Adriamycin+ Bleomycin). A total of 43 patients were entered in this trial, 23(53%) achieved at least a 50% reduction in tumor volume, 20(47%) showed no change. After completion of combination chemotherapy, 30(70%) of the 43 were done radical hysterectomy, 13(30%) given to radiotherapy. 9(30%) of the 30 patients were applied postoperative radiation therapy. Nausea and vomiting occurred in 35 of the 43 patients(81%) and alopecia 15(34%) for toxicity. Severe CNS toxicity(Grade 4) was detected in one patient. This study suggest that Ifosfamide combination chemotherapy is effective in tumor reduction and minimal toxity and can performed radical operation in cases of large tumor volume.

PURPOSE: To evaluate the clinical characteristics of intertrochanteric or subtrochanteric fractures associated with ipsilateral femoral shaft fractures and assess the surgical outcomes of a novel, closed intramedullary nailing surgical approach designed to minimize fixation failure. MATERIALS AND METHODS: Between May 2013 and April 2017, 31 patients with intertrochanteric or subtrochanteric fractures associated with ipsilateral femoral shaft fractures treated with closed intramedullary nailing or long proximal femoral nail antirotation (PFNA) were enrolled in this study. Preoperative data included age, sex, injury severity score, body mass index, location of shaft fracture, injury mechanism, accompanying traumatic injury, walking ability before injury, and surgical timing. Perioperative outcomes, including follow-up period, types of intramedullary nails, number of blocking screws used, operation time, and blood loss were assessed. Radiologic outcomes, including union rate, time from surgery to union, and femoral shortening, and clinical outcomes, including hip flexion, walking ability, and Harris hip score were also evaluated. RESULTS: A total of 29 unions (93.5%) were achieved. The time to union was 16.8 months (range, 11–25 months) for hip fractures (15.7 weeks for intertrochanteric fractures and 21.7 weeks for subtrochanteric fractures) and 22.8 months for femoral shaft fractures. There were no significant differences in surgical outcomes between the two groups except for type of intramedullary nail. CONCLUSION: Closed intramedullary nailing in the treatment of intertrochanteric or subtrochanteric fractures associated with ipsilateral femoral shaft fractures may be a good surgical option. However, fixation of femoral shaft fractures might not be sufficient depending on the implant design.
