Feasibility of FRAX for Prediction of Osteoporotic Vertebral Fractures in Korea

STUDY DESIGN: Retrospective study. PURPOSE: To assess the feasibility and limitations of fracture risk assessment tool (FRAX) for osteoporotic vertebral fractures in the Korean population. OVERVIEW OF LITERATURE: The FRAX algorithm is country specific and uses clinical risk factor data to calculate an individual patient's 10-year probability of hip fracture and 10-year probability of major osteoporotic fracture. However, it has not been adequately investigated for Korean. METHODS: One hundred ninety four patients who had all risk factor data for the calculation of FRAX were divided into two groups depending on the existence of vertebral fractures: the fracture group was comprised of 88 patients and the non-facture group comprised of 105 patients. We analyzed prediction of the fracture by applying respectively the Korean, Japanese, USA and UK model, and compared their FRAX results by calculating lumbar bone mineral density (BMD) instead of femoral neck BMD. RESULTS: The prediction of vertebral fracture using FRAX was 10.9 +/- 6.2% in the fracture group, 9.5 +/- 5.5% of the non-fracture group in the Korean model (p = 0.108); 17.9 +/- 10.2% in the fracture group, 14.6 +/- 9.0% in the non-fracture group in the Japanese model (p = 0.017). Only the Japanese model exhibited significant difference in vertebral fracture risk. The prediction of vertebral fracture using lumbar BMD instead of femoral neck BMD was 19.5 +/- 12.1% in the fracture group, 16.0 +/- 10.3% in the non-fracture group in the Korean model (p = 0.029). All models had statistically significant differences for the prediction of osteoporotic vertebral fracture. CONCLUSIONS: The 10-year probability of osteoporotic vertebral fracture had underestimation of the risk considering treatment eligibility based on the National Osteoporosis Foundation guidelines. BMD that accurately reflects the contribution of each result to fracture risk should be preferred for the prediction of fracture using FRAX, when lumbar spine and hip BMD measurements are both performed for clinical purposes in Korean.

Cementless Bipolar Hemiarthroplasty for Unstable Intertrochanteic Fractures in the Elderly / 대한정형외과학회잡지

PURPOSE: To evaluate the positive effects and problems through clinical and radiological results of cementless bipolar hemiarthroplasty for intertrochanteric fractures above type A2 in the elderly. MATERIALS AND METHODS: From December 2006 to June 2009, 54 bipolar hemiarthroplasties were performed in 54 patients in our hospital. The mean age was 78.8 (67-93) years. Of these cases, 13 were male and 41 were female. The fractures were of type A2.1 in 17 cases, type A2.2 in 23 cases and type A2.3 in 14 cases. There was no walking limitation in 45 patients, but 4 of the remaining 9 patients had walking limitations and used walking aids at their residence. A posterolateral approach as well as cementless femoral stems was used in all the patients. Clinical results were evaluated according to operation time, amount of bleeding, time to resume walking, duration of hospital stay, recovery of walking ability, and complications. Prostheses loss was evaluated on the follow-up radiographs. RESULTS: Twenty-two of 39 patients who had medical co-morbidity had more than two medical co-morbidities. Operations were performed at a mean time of 5.5 days after the fracture. The mean operation time was 95 minutes. The average total amount of bleeding was of 715 cc. Patients began walking at an average of 5.9 days after operation and the average duration of hospital stay was 19.2 days. Sixteen patients (29.6%) died at an average period of 1.6 years after their operation. At the time of discharge, 32 patients (59%) had recovered walking ability, but at the last follow-up compared to the pre-injury status, the recovery rate of walking had decreased to 46% (25 patients). Complications included a deep infection in one case, dislocation in 2 cases and hematoma in 2 cases. The cause of revision was deep infection. There were no revisions due to prosthesis loosening. CONCLUSION: Cementless bipolar hemiarthroplasty for intertrochanteric fractures in the elderly had some problems due to the prolonged operation time and increased amount of bleeding, but it also had advantages including the early return to walking after the operation and decreased hospital stay. It is one of the treatment options for the elderly with unstable intertrochanteric fractures.

Total Hip Arthroplasty Using Two-Incision Technique

BACKGROUND: To evaluate the effectiveness of minimally invasive surgery total hip arthroplasty (THA) using the two-incision technique as described by Mears. METHODS: From January 2003 to December 2006, sixty-four patients underwent total hip arthroplasty using the one-incision (group I) and two-incision (group II) technique by one surgeon. There were 34 hips in group I and 30 hips in group II. There was no difference in age, gender, and causes of THA between the two groups. We evaluated the operation time, bleeding amount, incision length, ambulation, hospital stay, and complications between the two groups. RESULTS: There was no difference in the bleeding amount between the two groups. Operation time was longer in the two-incision group than in the one-incision group. Operation time of the two-incision technique could be reduced after 15 cases. Patients started ambulation after surgery earlier in group II than group I, and the hospital stay was shorter in group II than in group I. There was no difference in clinical results between the two groups. There was no difference in component position of the acetabular cup and femoral stem between the two groups. Intraoperative periprosthetic fracture occurred in four cases (13.3%) in group II. CONCLUSIONS: Two-incision THA has the advantage of rapid recovery and shorter hospital stay. However, longer operation time and a high complication rate compared to one-incision are problems that need to be solved in the two-incision technique.

Comparative analysis on the effectiveness of transvaginal radiofrequency myolysis for conservative management of leiomyoma and adenomyosis / 대한산부인과학회지

OBJECTIVE: To compare the clinical effectiveness of transvaginal radiofrequency myolysis of the patients with leiomyomas and the patients with adenomyosis which have similar clinical symptoms. METHODS: From May 2005 to May 2006 at Eulji university hospital, 108 women who were diagnosed of leiomyoma and adenomyosis had undergone transvaginal radiofrequency myolysis. Before and after the procedure size, number of uterine myomas, location and the volume of the leiomyomas and adenomyosis were measured by ultrasound. And on every visit after the procedure improvement of the symptom was checked by questionnaire of the symptom and life quality. Using Wilcoxon signed ranked test, the statistical significance was proved and the P value lower than 0.05 was judged to be significant. RESULTS: 76 women with leiomyoma who had undergone transvaginal radiofrequency myolysis, were followed up 1 month, 3 months, 6 months and 9 months after the procedure. The average maximal diameter of the myoma was decreased by 14.6%, 23.3%, 30.6%, 33.6% respectively, and the average volume was decreased by 35.7%, 53.3%, 67.3%, 72.2% respectively. 32 women with adenomyosis who had undergone transvaginal radiofrequency myolysis were followed up, at the same period after the procedure. The average maximal diameter of the adenomyosis was decreased by 8.9%, 13.6%, 14.6%, 11.9% respectively, and the average volume was decreased by 22.6%, 30.0%, 32.3%, 28.4% respectively. Before and after the procedure the symptom score was 62.3, 52.2, 40.6, 32.6, 28.6 respectively, and the quality of life score was 68.9, 78.1, 82.9, 85.7, 87.3 respectively in the leiomyoma group. In the adenomyosis group, before and after the procedure the symptom score was 77.7, 37.6, 30.6, 54.4, 67.5 respectively, and the quality of life score was 48.1, 76.5, 85.5, 66.5, 55.1 respectively. CONCLUSION: Transvaginal radiofrequent myolysis had benefits in conserving the uterus, and was less invasive, and had great effect on the reducing the size of the leiomyoma and improving the symptoms, and also returning to normal life pattern was earlier. But in women with adenomyosis the symptoms were worsened after approximately 6 to 9 months after the procedure. Therefore additional research and follow-up is required and a strict criterion is needed.

A Case of Placenta Increta in the Uterine Sacculation which was Treated with Conservative Methods / 대한주산의학회잡지

Uterine sacculation is a very rare complication associated with pregnancy in which a part of the uterine wall balloons, and it is difficult to diagnose because it is usually asymptomatic. It frequently contains the placenta and sometimes may be involved with the trapped placenta after delivery due to its structural characteristic. It is impossible to remove the retained placenta in the sac by using usual methods such as manual delivery or curettage so most of patients with it end up with having a laparotomy. Especially, if the placenta in it is accompanied by abnormal adherence of the placenta or serious hemorrhage, hysterectomy should be considered. Currently several conservative methods for the retained placenta including selective uterine artery embolization and administration of methotrexate have been introduced and these may be tried to treat the retained placenta in the uterine sacculation for avoiding operation and preserving future reproductive potential in selective cases. We experienced a case of placenta increta in the uterine sacculation that was diagnosed first during cesarian section and was treated with selective uterine artery embolization followed by methotrexate administration. This case is reported with a brief review of the literatures.

The comparison of laparoscopic assisted vaginal hysterectomy, total vaginal hysterectomy and total abdominal hysterectomy / 대한산부인과학회지

OBJECTIVE: To compare the clinical results for women undergoing total abdominal hysterectomy (TAH), laparoscopic assisted vaginal hysterectomy (LAVH) and total vaginal hysterectomy (TVH). METHODS: We reviewed the medical records of patients who underwent TAH (n=97), LAVH (n=112) and TVH (n=95) from June 2002 to June 2005. We compared and evaluated patient's characteristics, previous abdominal operation histories, indication of hysterectomy, uterine weight, operative time, perioperative hemoglobin and hematocrit change, the degree of postoperative pain, hospital stay and complications. RESULTS: The patient's characteristic (age, weight, height, parity, perioperative hemoglobin and hematocrit change, complication rate) had no statistical difference in all three groups. In the TVH group, the rate of previous abdominal operations (25%) was significantly lower than TAH (56%), and LAVH (40%) (p=0.023). The mean uterine weight was the heaviest in TAH group (443.6+/-407.3 g), compared to LAVH group (301.9+/-133.9 g) and TVH group (225.3+/-91.8 g) (p<0.001). Operative time was the longest for LAVH group (p=0.001), and there was no significant difference between TAH group and TVH group (p=0.087). The TAH group had the highest postoperative pain scale and the length of hospital stay. The LAVH group and TVH group had almost the same postoperative pain scale and the length of hospital stay. CONCLUSION: Both LAVH and TVH had the following advantages compared with total abdominal hysterectomy: less pain, shorter hospital stay, cosmetic advantages. But limited operation field in TVH and expensive operative cost in LAVH were disadvantages. Specific guidelines for determining the route of hysterectomy result in decreased morbidity and lower costs, and thus the gynecologist can ensure that the patient receives the best possible surgical care.

A Case of Peripartum Cardiomyopathy associated with Preeclampsia superimposed on Idiopathic Thrombocytopenic Purpura / 대한산부인과학회지

Peripartum cardiomyopathy is a dilated cardiomyopathy of unexplained cause that occurs during the last trimester of pregnancy or within 5 months after delivery. And, It is a rare disease that has a frequency of 1 in 1,300-15,000 deliveries. It has not yet been reported that peripartum cardiomyopathy has occurred in an preeclampsia woman superimposed on idiopathic thrombocytopenic purpura. Moreover, the association between idiopathic thrombocytopenic purpura and peripartum cardiomyopathy has not been studied. Recently, we experienced a case of a woman who has undergone emergency Cesarean section due to complicated severe preeclampsia superimposed on idiopathic thrombocytopenic purpura. On the postoperative day, this patient developed respiratory distress and pumonary edema. Peripartum cardiomyopathy was diagnosed by echocardiography and we present with a brief review of literatures.
