To determine whether simple curettage is recommendable for the solitary enchondroma of hand, the results of the simple curettage and the curettage with bonegraft were compared in the respects of operation time, the degree of new bone formation, healing time and complications. Thirty five patients have been evaluated to assess the results of treatments. The bone healing and the degree of new bone formation have been evaluated according to the criteria of Tordai (l990). The bone healing had been achieved at average 7.4 months after operation in the simple curettage group and at average 4.6 months in the curettage with bonegraft group (P<0.05). According to Tordai's criteria, among the simple curettage patients, 9 cases (64%) were group I, 5 cases (36%) were group II, no case was group III. Among the curettage with bonegraft patients, 16 cases (76%) were group I, 4 cases (19%) were group II, 1 case (5%) was group III. No significant difference was observed between the two groups in the degree of new bone formation (P=0.05). Although the healing time was longer in the simple curettage group, no significant difference was found in the degree of new bone formation. The pain of the bone donor site was absent in the simple curettage group, and the simple curettage can reduce the operation time. The curettage alone is a recommendable treatment for solitary enchondroma in hand.

Although tubuloglomerular feedback (TGF) is involved in ureteral obstruction-induced increase in renal blood flow (RBF), its contribution to RBF is not well established due to the concommitant increases in prostaglandin (PG) and renal interstitial fluid pressure (Pisf), both of which affect RBF one way or the other. Since Pisf and TGF are closely affected by renal hemodynamics, RBF will respond differently to increases in ureteral pressure depending on renal hemodynamic conditions. Therefore, the purpose of the present study was to investigate how the changes in renal hemodynamics affect the response of RBF to increases in ureteral pressure. The effect of PG on RBF was assessed by comparing the effects obtained before and after indomethacin, a cyclooxygenase inhibitor. Six anesthetized dogs were prepared with flow probes and inflatable silastic occluder around the renal artery, the ureteral catheter with its free end attached to a water reservoir, and the arterial and venous catheters. RBFs were obtained at ureteral pressures of 0, 15, and 40cmH2O during the maintenance of the renal artery pressure (RAP) at the level of systemic arterial pressure, 10mmHg above and below the lower autoregulatory limit of RBF (65+/-4 mmHg) both before and after indomethacin administration (10mg/kg). In response to the ureteral pressure of 40cmH2O, RBF increased from 172+/-6 to 185+/-10ml/min when RAP's were equal to systemic arterial pressure and decreased from 162+/-10 to 120+/-9 ml/min when RAP's were 55+/-4mmHg. Indomethacin pretreatment, depending on the level of RAP either prevented an increase or augmented a decrease in RBF in response to ureteral pressure elevation. This suggests that RAP-dependent changes in susceptibility of the renal venous system to compression by increased Pisf is the main mechanism by which the changes in renal perfusion pressure modulate the response of RBF to ureteral pressure elevation.

Pigmented villonodular synovitis (PVNS) is a relatively rare condition. The disorder almost always involves a single joint and the knee is most commonly affected. We report on three cases of localized PVNS that involved the patella fat pad and synovium. Diagnostic and therapeutic arthroscopies were performed, and typical findings of localized PVNS were found. Complete resection of the lesions were performed arthroscopically. Arthroscopy can be used as an effective diagnostic and therapeutic tool for identification and resection of intraarticular localized PVNS of the knee.

Ganglion cysts of the cruciate ligament are quite rare. Ganglion cysts on the anterior cruciate ligament(ACL) should be suspected in any patient having pain and clicking sensation during terminal knee extension. A few cases have been reported concerning ganglion cysts present on the surface of the anterior cruciate ligament. We report three cases of a ganglion cysts on the ACL that was treated with arthroscopic excision.

In 1971, for purpose of reduction of peak stress occuring in cement and trabecular bone of the acetabulum, Harris reported a series of metal-backed acetabular components with removable polyethylene liners that could be replaced if excessive wear occured. Modular designs of hip prostheses have become popular recently, but they introduce the risk of disassembly of the components postoperatively. And introduce of loosening and infection of femoral or acetabular components by debris of polyethylene liner. We report a case of mechanical disassembly of polyethylene liner in cementless metal backed cup, and review previously reported articles.

The fabella is the seasmoid bone occurring in about 10–30% of individuals and is located in the head of the lateral tendon of the Gastrocnemius muscle. Fracture of the fabella is a very rare condition. Since first reported by Jacob Sagel in 1932, only 5 cases of fabella fracture had been reported. However, there has been no bilateral case. We report a first case of bilateral fracture of the fabella with review of literature. This case was combined with rupture of anterior cruciate ligament and lateral collateral ligament on the right knee.

OBJECTIVES: The purpose of this study was to assess anger of middle school adolescents in an urban community using State-Trait Anger Expression Inventory (STAXI)-Korean and Korean Child Behavior Checklist (K-CBCL), and to determine whether specific anger expression of adolescents is associated with certain psychopathology including depression. METHODS: Data were collected from 395 middle school students and their parents in Incheon city. The students completed the STAXI, Children's Depression Inventory, Korean version of Mood disorder Questionnaire, and Conners-Wells' Adolescent Self-Report Scale (Short Form), and their parents completed the K-CBCL. RESULTS: No significant correlation was observed between aggression subscale K-CBCL and each scale of the STAXI, except anger out (r=0.704). The scores for STAXI total and respective scales were significantly higher for female students than male students. A stepwise logistic regression model was used to explore the possible predictors for depression in adolescents and lower anger control and higher anger suppression were found to be predictors for depression in adolescence. CONCLUSION: There is a possibility of a large discrepancy between anger that the adolescents actually feel and parents' judgment of their children's anger. It must be considered in assessment of adolescent anger and use of further structured interviews is necessary. In addition, it may be useful to consider the anger expression style in adolescents who report depressive symptoms.
