One hundred and twenty seven patients with uterine cervical carcinoma underwent computed tomography(CT) and magnetic resonance(MR) imaging, followed by surgical exploration. MR imaging was superior to CT in visualization of the tumor, for parametrial evaluation, and for tumor staging. MR imaging had an accuracy of 74% in the assessment of thickness of cervical stromal invasion. The accuracy rates for parametrial evaluation were 78% for CT and 88% for MR imaging. The overall accuracy rates for tumor staging were 68% for CT and 80% for MR imaging. The accuracy rates for pelvic lymph node evaluation were 82% for CT and 85% for MR imaging. Our findings suggest that MR imaging is supperior to CT in preoperative staging of uterine cervical carcinoma.

Background: The purpose of this study was to investigate the characteristics of osteoporotic vertebral compression fractures (OVCFs) in Korean postmenopausal women and the association between OVCFs and clinical factors such as age, bone mineral density (BMD), and quality of life. Methods: According to the population distribution in four regions in Korea, 1,281 postmenopausal female patients were recruited from nationwide orthopedic outpatient clinics. Radiologic, asymptomatic, and within 3 months of OVCF groups were analyzed based on age, fracture location, and prevalence according to BMD. In addition, BMD, T-score, body mass index, and European Quality of Life-5 Dimensions (EQ-5D) were investigated in the three groups, and the differences between groups were compared and analyzed. Results: The prevalence of radiologic OVCFs at the T11–L1 was 3.7 times higher in the 70s group (44.0%) than in the 50s group (11.9%). Femur and total hip BMD were significantly lower in patients with thoracolumbar junction fractures than in patients with L2–5 fractures, whereas no difference was observed in lumbar spine BMD. Of the three OVCF groups, the within 3 months of OVCF group had the lowest lumbar spine T-score of –2.445. The asymptomatic OVCF group also showed significantly lower lumbar spine T-score than did the group without radiologic OVCFs (p < 0.001). The EQ-5D showed a significant decrease in the radiologic OVCF group (p < 0.001) and within 3 months of OVCF group (p < 0.001). Conclusions The prevalence of OVCFs in the thoracolumbar junction rapidly increases with old age and low BMD in Korean postmenopausal women. Femur and total hip BMD are more predictive of thoracolumbar junction fractures than lumbar spine BMD.Patients with radiologic OVCFs had a significantly lower quality of life than no OVCF group. Therefore, this study shows it is important to treat and prevent osteoporosis before an OVCF occurs.

BACKGROUND: To determine the benefit of an extensively porous coated femoral stem in patients receiving revision total hip arthroplasty. METHODS: This study reviewed the results of 35 patients who received a revision total hip arthroplasty with extensively porous coated femoral stem between August, 1996, and December, 2002. The mean follow-up period was 77.5 months. The clinical and radiological results were evaluated by the Harris hip score and serial roentgenographic findings. RESULTS: The preoperative and postoperative Harris hip score was 68.3 and 92.5, respectively. Radiographically, none of the acetabular components showed any evidence of migration, tilt, rotation, or shedding of metal particles. In addition, none of the femoral components showed evidence of subsidence, pedestal, or shedding of metal particles. Twenty-two hips had a mild stress shield and 2 hips had a moderate stress shield. The perioperative complications encountered were deep vein thrombosis (1 case), mild heterotopic ossification (4 cases), intraoperative periprosthetic fractures (1 case), and nonunion of the trochanteric osteotomy site (2 cases). CONCLUSIONS: Extensively porous coated femoral stems and acetabular components produce excellent clinical and radiological results in revision total hip arthroplasty.

Uterine cervical carcinoma is one of the most common malignant tumors occur-ring in females. After primary treatment, patients are usually followed up with CT or MRI and the findings of these modalities may be the first sign of recurrent disease. Because earlier additional treatment by chemotherapy or radiation therapy may improve the prognosis, the early detection of recurrent cervical carcinoma is clinically important. In this article, we review the CT and MR imaging findings of recurrent uterine cervical carcinoma, and assign them to one of four groups: a)recurrence at the primary site, involving the intrapelvic organs, b) extension to the pelvic side-wall, c) metastases to pelvic and extrapelvic lymph nodes, or d)metastases to distant organs. A further contribution of CT and MR imaging is the detection of hydronephrosis due to ureteral obstruction. The cases in each group are illustrated and discussed, and since an awareness of the spectrum of imaging findings of recurrent cervical carcinoma is likely to lead to its early detection, radi-ologists should be familiar with the information presented.

Low dose finasteride(1mg/d, Propecia(R)) has been widely used as an effective treatment for male androgenetic alopecia. Finasteride is an inhibitor of 5-alpha-reductase, the enzyme responsible for testosterone metabolism to dihydrotestosteron(DHT). We report a case of painful, unilateral idiopathic gynecomastia aggravated by low dose finasteride for male androgenetic alpopecia. A 23-year-old man started treatment with Propecia(R), 1 mg per day. Two months later he presented with a painful enlargement of his right breast. Treatment was stopped and two months later the clinical manifestration had disappeared.
