Pain, traumatic arthritis, joint stiffness and joint subluxation are common sequelae of fracture dislocations of the proximal interphalangeal joints of the finger. Many kinds of methods were used to treat fracture dislocation of the proximal interphalangeal joint. The prognosis is greatly influenced by the method and the time of treatment. Authors treated 4 cases of fracture dislocations of the proximal interphalangeal joint with 3 different method. For a case with small bony fragment, we used the extension block splint of McElfresh. For a old case, we used the volar plate arthroplasty mothod of Eaton. And for two cases with large bony fragment, we used the force couple splint method of Agee after open reduction and internal fixation. The results were satisfactory.

A case of malignant melanoma occures in the palpebral conjuntiva is presented. A 60 years old female had dark brownish. strowbery-like peduncleated mass in her right upper conjuntiva. The tumor mass was excised radically and confirmed as malignant melanoma histopathologically and she received cobalt 60 irradiation. No recurrence was seen for 4 months since the excision of the mass.

OBJECTIVE: Human embryonic stem (ES) cells have a great potential in regenerative medicine and tissue engineering. The human ES cells could be differentiated into specific cell types by treatments of growth factors and alterations of gene expressions. However, the efficacy of guided differentiation and isolation of specific cells are still low. In this study, we characterized isolated cells from differentiated human ES cells by magnetic activated cell sorting (MACS) system using specific antibodies to cell surface markers. METHODS: The undifferentiated hES cells (Miz-hESC4) were sub-cultured by mechanical isolation of colonies and embryoid bodies were spontaneously differentiated with DMEM containing 10% FBS for 2 weeks. The differentiated cells were isolated to positive and negative cells with MACS system using CD34, human epithelial antigen (HEA) and human fibroblast (HFB) antibodies, respectively. Observation of morphological changes and analysis of marker genes expression were performed during further culture of MACS isolated cells for 4 weeks. RESULTS: Morphology of the CD34 positive cells was firstly round, and then it was changed to small polygonal shape after further culture. The HEA positive cells showed large polygonal, and the HFB positive spindle shape. In RT-PCR analysis of marker genes, the CD34 and HFB positive cells expressed endodermal and mesodermal genes, and HEA positive cells expressed ectodermal genes such as NESTIN and NF68KD. The marker genes expression pattern of CD34 positive cells changed during the extension of culture time. CONCLUSION: Our results showed the possibility of successful isolation of specific cells by MACS system from undirected differentiated human ES cells. Thus, MACS system and marker antibodies for specific cell types might be useful for guided differentiation and isolation of specific cells from human ES cells.

PURPOSE: Primary osteoarthritis on the elbow is the result of the growth of osteophytes and contracture of the capsule. It often causes disability on joint motion and pain while exercising. As arthroscopy has developed, the arthroscopic diagnosis and treatment of the elbow have recently become more generalized as well. Therefore, we like to report on arthroscopy for treating elbow arthritis and its results. MATERIALS AND METHODS: This study includes 23 cases of elbow arthritis that were seen between 2005 June to 2007 June and these patients didn't response to conservative treatment. From this we excluded 18 cases that underwent arthroscopic surgery and among these 18 cases, 6 cases underwent ulnar nerve transfer. The average observation time was 21.3 months and the average age was 48.4 years (range: 22-66 years). The pre and post operative pain was evaluated with using the Visual Analogue Scale (VAS) and functional evaluation was done with using the Mayo elbow Performance Score (MEPS) with the range of joint motion. RESULTS: The VAS score at the last follow up was significantly decreased from 3.4 to 1.9 compare to the preoperative score. The range of joint motion was improved by 25 (0-40) to 8.5 (0-20) in extension and 101.7 (80-140) to 125.2 (85-140) in flexion (p<0.05). The MEPS always showed significant improvement by showing an increase from 65.4 (40-85) to 87.9 (55-100). However, 3 cases showed a decreased range of motion after the operation. One case showed ulnar nerve symptoms after surgery. CONCLUSION: An arthroscopic procedure can treat the pathologic processes associated with arthritis of the elbow and it was safe and effective in this series.

Congenital dislocation of the knee is very rare skeletal deformity and was firstly described by Chatelaine in 1822. Since then there have been a few number of case reports and some series discussing the etiology and treatment. The tibia is displaced anteriorly in relation to the femur. It is generally subdassified as simple hyperextention, subluxation, and dislocation depending on the degree of the joint displacement and the severity of disease. Early gentle manipulation and serial splintage or plaster cast are recommended for treatment and were successful in the majority except the case of quadriceps contrarture or late correction. The authors experienced one case of congenital dislocation of the right knee and brief review of the related literatures was made.

PURPOSE: The effects of gonadotropin-releasing hormone agonist (GnRHa) treatment on the energy metabolism in girls with central precocious puberty (CPP) are controversial. We focused the changes and related factors of serum levels of leptin and adiponectin in girls with CPP before and during GnRHa treatment. METHODS: Thirty girls with idiopathic CPP were enrolled in the study. Their auxological data and fasting blood were collected at the baseline and after six months of GnRHa treatment. RESULTS: After treatment, height (P<0.001), weight (P<0.001), and serum leptin levels (P=0.033) were significantly increased, whereas body mass index (BMI), homeostasis model of assessment-insulin resistance, serum adiponectin levels, and adiponectin/leptin ratio exhibited no significant changes. A Pearson correlation analysis showed that height, weight, BMI, and their standard deviation scores (SDSs), but not basal LH, FSH, and estradiol, were significantly correlated with serum leptin levels before and after GnRHa treatment. After a multiple linear regression analysis, only BMI was associated with serum leptin levels. Moreover, leptin SDSs adjusted for BMI were not significantly different before and after GnRHa. The Δ leptin levels (r2=0.207, P=0.012), but not with Δ leptin SDS (r2=0.019, P=0.556), during GnRHa treatment were positively correlated with Δ BMI. CONCLUSION: These results suggest that GnRHa treatment in girls with CPP does not affect serum levels of leptin and adiponectin and insulin resistance. Serum leptin levels were depend on the changes in BMI during GnRHa treatment.
