Osteoporosis is a disease characterized by excessive bone loss or osteopenia particulary in the axial skeleton at the site of fracture, such as the spine and proximal femur. Since the strength of both spine and femur is directly proportional to the bone mass, this osteoporosis always increases the risk of fracture. In this study, to evaluate whether a simple measurement of femoral geometry and BMD value are related with hip fracture, we obtained DEXA Scan (Lunar Expert-XL) of hip by retrospective study. DEXA scan was measured on 70 control people and 17 hip fracture patients aged 50 or older. The result is I. The mean Ward BMD value of hip fracture group is significantly lower than control group (Hip fracture group: 0.52g/cm2, Control group: 0.67g/cm2 P=0.0001) 2. The mean L-spine BMD value of hip fracture group is significantly lower than control group (Hip fracture group: 0.81g/cm, Control group: 0.97g/cm2 P=0.0002) 3. The mean femur axis length of hip fracture group is longer than control group (Hip fracture group: 6.77g/cm2, Control group: 6.57g/cm2 P=0.006) As a conclusion, the measurement of BMD and hip axis length in DEXA scan is an effective method for screening the hip fracture risk patient and BMD value of femur, hip axis length and L- spine BMD value are strongly associated with hip fracture.

Leiomyomas are the most common benign tumors of the uterus, and although they can occur at any site in the genitourinary tract, they very rarely originate from the urinary bladder. We report a case in which a leiomyoma occurred at that site, deseribing the US, CT, and MRI findings.

Giant cell tumor is a predominantly benign condition but often the tumor is locally aggressive and tends to have high rate of recurrence and it can evolve into a malignant tumor. Thus the lesions have a practically difficult therapeutic problem for the orthopaedic surgeon and any method of treatment has not been satisfied. Between March 1984 and March 1993, clinical observation was carried out on 22 cases of giant cell tumor of bone to analyse the recurrence rate and functional evaluation of the joint according to the treatment methods, pathological grade and cortical destruction. The mean follow-up time was 75. 2 months. The recurrence rate of the intralesional excision group was 54.5% and that of the wide excision group was 9%, There was no relationship between the pathologic grade and recurrence rate. There was no recurrent case in the grade I cortical destruction but almost all of recurrence was occurred in the grade I or II cortical destruction. The functional result of the giant cell tumor occurred around the knee joint was that the mean ratings in the intralesional excision group were 79% and in the wide excision group were 51%. In conclusion, to achieve better joint function and less recurrence rate, intralesional or marginal excision with heat using bone cement or with chemical cauterization using phenol and alcohol can be used for cases of radiological grade I or II, and wide excision for grade III.

BACKGROUND: Totally implantable access port (TIAP) provides reliable, long term vascular access with minimal risk of infection and allows patients normal physical activity. With wide use of ports, new complications have been encountered. We analyzed TIAP related complications and evaluated the outcomes of two different percutaneous routes of access to superior vena cava. METHODS: All 172 patients who underwent port insertion with internal jugular approach (Group 1, n = 92) and subclavian approach (Group 2, n = 79) between August 2011 and May 2013 in a single center were analyzed, retrospectively. Medical records were analyzed to compare the outcomes and the occurrence of port related complications between two different percutaneous routes of access to superior vena cava. RESULTS: Median follow-up for TIAP was 278 days (range, 1-1868). Twenty four complications were occurred (14.0%), including pneumothorax (n = 1, 0.6%), migration/malposition (n = 4, 2.3%), pinch-off syndrome (n = 4, 2.3%), malfunction (n = 2, 1.1%), infection (n = 8, 4.7%), and venous thrombosis (n = 5, 2.9%). The overall incidence was 8.7% and 20.3% in each group (p = 0.030). Mechanical complications except infectious and thrombotic complications were more often occurred in group 2 (p = 0.033). The mechanical complication free probability is significantly higher in group 1 (p = 0.040). CONCLUSIONS: We suggest that the jugular access should be chosen in patients who need long term catheterization because of high incidence of mechanical complication, such as pinch-off syndrome.

An association study with Korean alcoholic patients(n=50) and normal controls(n=53) was performed to find the relationship between catechol-O-methyltransferase(COMT) gene polymorphism and alcoholism using polymerase chain reaction-restriction fragment length polymorphism. When we compared the allele and genotype frequencies of Nla III COMT gene polymorphism in alcoholism and normal controls, there was no significant difference between two groups. Our results do not support an association between the Nla III polymorphism of COMT gene and alcoholism.
