We found that the packing of a rolled tensor fascia lata flap after the excision of avascular lunate was reasonably effective in relieving symptoms in 4 patients with advanced Kienbock's disease, even though there was still some residual postoperative loss of wrist motion and grip strength, and the slightly progressive tendencies of earpal collapse and translation as well as rotational deformities of scaphoid. Pre-operatively all patients had pain and limited motion of the wrist as well as weakness of grip. Roentgenographically all had sclerosis, fragmentation and collapse of the lunate. They were analysed each two cases in advanced stage II and III according to the classification by Lichtman. Most had symptoms for longer than two and half years. After removal of the avascular lunate through a dorsal incision, a rolled tensor fascia lata flap was packed to fit the defect. Patients were followed for an average of sixteen months. All were improved clinically but there were somewhat postoperative progress in carpal collapse, translation and rotational deformities of scaphoid roentgenographically.

A multiple regression analysis using ordinary least square (OLS) is frequently used for the projection of healt expenditure as well as for the identification of factors affecting health care costs. Data for the analysis often have mixed characteristics of time series and cross section. Parameters as a result of OLS estimation, in this case, are no longer the best linear unbiased estimators (BLUE) because the data do not satisfy basic assumptions of regression analysis. The study theoretically examined statistical problems induced when OLS estimation was applied with the time series cross section data. Then both the OLS regression and time series cross section regression (TSCS regression) were applied to the same empirical data. Finally, the difference in parameters between the two estimations were explained through residual analysis.

PURPOSE: Osteoporosis is generally regarded as disease of women and there are extensive data about post-menopausal osteopotosis, but there is relatively little information concerning the osteoporosis in aging male. We aimed to determine the relationships between age ,androgen and bone mineral density (BMD) in elderly korean men. MATERIALS AND METHODS: We evaluated the sex hormones and BMD of 82 elderly men between May 1999 and April 2000. Serum free testosterone (FT), total testosterone (TT), DHT, LH, FSH and Prolactin were measured by RIA. BMD at anteroposterior L2-4, femoral neck, ward's triangle, femoral trochanter and femoral shaft were determined by dual-energy X-ray absorptiometry. We defined group I as free testosterone <10ng/dl and group II as 10ng/dl. RESULTS: Serum LH and FSH increased with age. There was a significant decrease in serum FT with age, but T concentrations remained unchanged. There were significant declines with age in BMD at femoral neck, Ward's triangle, femoral trochanter, femoral shaft. Serum FT were significantly correlated to BMD at anteroposterior L2-4, femoral neck, Ward's triangle, femoral trochanter, femoral shaft. After controlling for age, serum FT were significantly correlated to BMD at femoral trochanter, femoral shaft. Mean BMD was significantly lower in group I than group II at anteroposterior L2-4, femoral shaft. CONCLUSIONS: We suggest that FT is a male osteoporotic marker in man older than 50 years and bone mineral density should be considered for diagnosis of male osteoporosis associated with PADAM, especially when FT is lower than 10ng/dl.

9.Latissimus Dorsi Flap for Breast Reconstruction.

Breast reconstruction following mastectomy has, become increasingly popular in recent years. Reconstruction surgeons have responded to patients' needs for effective and versatile procedures that will restore the normal shape and symmetry of breasts. Among the various techniques for these purpose, transverse rectus abdominis myocutaneous(TRAM) flap is now cosidered as the most acceptable technique. However, there are some limitations to use the TRAM flap, such as heavy smoker, obesity, and previous abdominal surgery. Also TRAM flaps are not good candidates for the patients with absent anterior axillary fold. In these respects, latissimus dorsi flap can be used as an alternative method for successful breast reconstuction. Latissiomus dorsi flaps have several advantages as compared to TRAM flaps, such as reliable blood supply, versatility of skin paddle orientation, and low donor site morbidity. It is also available for patients without anterior axillary fold, such as radical mastectomy defect or Poland syndrome. Latissimus dorsi flaps, however, and implants to obtain projection and symmetry of the reconstructed breast. Main disadvantages of latissimus dorsi flap method are difference in color and texture between skins of flap and chest, and capsular contracture resulted in high riding implant or distortion of breast contour. In this study, we performed latissimus dorsi flap for reconstruction fo breast and anterior axillary fold in 10 cases. To minimize the above problems more fullness and natural shape, implants were completely covered with muscle and overexpanded for more than 3-months and then deflated to the desired volume. These maneuvers produced aesthetically acceptable results during the latissimus dorsi breast reconstruction.

With increasing tendency of incidence and interest for the late onset schzophrenia, concerns about whether this disorder is etiologically or phenomenogically distinctive entity or not have increased also. To clarify the disease entity of the late onset schzophrenia and the role of structural brain changes in its etiology, authors tried to prove following hypothesis : Are there any evidences of structural brain changes in the late-onset schizophrenia? ; If present, are they not different from those of the early-onset schizophrenia or progressive schizophrenia? ; And are they not different from those of senile dementia? Subjects were 6 patients with the late-onset schizophrenia, 6 patients with the early-onset schizophrenia, 6 patients with progressive schizophrenia, 6 patients with Alzheimer's dementia, and 6 controls. We measured regions of interest of the magnetic resonance images by computer assisted planimetry using the AutoCad and digitizer. Our study results may suggest that the third ventricular enlargement and a reversal of normal difference between left and right temporal lobe and left-right difference in posterior lateral ventricle are common brain pathology for all type of schizophrenia including the late onset schzophrenia. And also suggest that brain structural changes of the late onset schizophrenia are related with neurodevelopmental abnormality rather than degenerative change.
