The percutaneous pinning is a simple, effective method for the treatment of displaced supracondylar fractures of the humerus in children. But there is some controversy in the number of pins used and the method of pin insertion. The cross pinning method provides more stability at the fracture site but the risk of ulnar nerve damage is higher than in lateral pinning method, The senenty-one displaced extension type supracondylar fractures were treated by closed reduction and percutaneous cross pinning from January 1991 to October 1994. Among them, the medial pin was inserted in elbow extension in twenty-eight cases and in forty- three cases the medial pin was inserted in elbow flexion. Ulnar nerve injury occured postoperatively in six cases, in which the pin was inserted with the elbow in flexion position. These results may suggest that when percutaneous cross pinning method is selected to fix the supracondylar fracture of the humerus, it would be safer to insert one or two lateral pins with the elbow in full flexion position followed by one medial pin in extension position in order to reduce the risk of loss of reduction and ulnar nerve damage.

OBJECTIVES: This study was designed to investigate the association between Ser311/Cys311 polymorphism in the dopamine D2 receptor gene and bipolar disorder in korean population. METHOD: Ser311/Cys311 polymorphism in the dopamine D2 receptor gene was typed with PCR in 86 bipolar disorders and 100 normal controls. RESULTS: Genotype of Ser/Ser, Ser/Cys, Cys/Cys were 82 (95.3%), 4 (4.7%), 0 (0.0%) respectively in the bipolar disorders, 96 (96.0%), 4 (4.0%), 0 (0.0%) respectively in the controls. Allele frequencies of Ser and Cys were 168 (97.7%), 4 (2.3%) in the bipolar disorders, 196 (98.0%), 4 (2.0%) in the controls. There were no differencies in genotype distribution and allele frequencies of dopamine D2 receptor gene polymorphism Ser311/Cys311 between in the bipolar disorders and in the controls. CONCLUSION: These result suggests dopamine D2 receptor gene polymorphism Ser311/Cys311 is not causally related to the development of bipolar disorder in korean population.

Villous tumor of the duodenum are rare, only 89 cases having been reported and reviewed in several recent publication. Malignancy is discovered in approximately 30-45% leading to the recommandation that all such tumors be excised regardless of the endoscopic findings. Two cases of villous tumor of the duodenum were reported and locally excised. The pathologic specimens showed carcinoma in situ, no evidence of hematogenous and lymphatic metastasis.

PURPOSE: A significant number of patients who have experienced previous surgical treatment for an osteoporotic hip fracture experience a subsequent hip fracture (SHF) on the opposite side. This study aims to analyze the risk factors and the correlation between osteoporosis and SHF on the opposite side in order to assess the usefulness of bisphosphonate treatment for the prevention of SHFs. MATERIALS AND METHODS: We included 517 patients treated from March 1997 to April 2009 in this study. The inclusion criteria included previous unilateral hip fracture, without osteoporotic treatment, and a T-score less than -3.0 at the time of the fracture. We studied these patients in terms of death, SHF, alcoholism, living alone, dementia, dizziness, health status, osteoporotic treatment after fracture and bone mineral density (BMD). In total, 34 patients experienced a SHF. We selected another 34 patients without a SHF who had similar age, sex, body mass index, BMD, diagnosis, treatment and a follow up period for a matched pair study. We compared these two groups. The average follow up was 8.3 years and 8.1 years, respectively. RESULTS: The mortality rate of the 517 patients was 138 (27%). The BMD at the time of fracture demonstrated no statistical difference between the two groups (p>0.05). Nine patients (26%) within the SHF group were prescribed Risedronate and 18 patients (53%) received the same treatment in the non-SHF group. There was a statistical relationship with the treatment of osteoporosis (p=0.026). The average BMD of patients with SHF was -5.13 and -5.02 in patients without SHF was (p>0.05). CONCLUSION: Although primary surgical treatments are important for an excellent outcome in osteoporotic hip fractures, treatment of osteoporosis itself is just as important for preventing SHFs.

Journal of the Korean Fracture Society 2015;28(3):169-177
PURPOSE: The purpose of this study was to evaluate the use of hinged external fixation in management of complex elbow injury. MATERIALS AND METHODS: We retrospectively reviewed clinical outcomes in 10 patients with elbow dislocation and associated fractures of both the radial head and the coronoid process from January 2007 to December 2013. All ten patients were treated by hinged external fixation after open reduction and internal fixation. The indication for use of a hinged external fixator was persistent instability after fixation of the fractures. Early mobilization was started at 1 week (6.5 days) after surgery. The external fixator was removed at 6 weeks after surgery. Cassebaum classification and Mayo elbow performance score were used for clinical and functional evaluation. The follow-up period was at least 1 year. RESULTS: At the last follow-up, the average further flexion was 127degrees, and the average flexion contracture was 16degrees. The average pronation was 83degrees and the average supination was 78degrees. By the Cassebaum classification after 1 year follow-up, patients were classified as 4 excellent, 4 good, and 2 poor. According to the Mayo elbow performance score, the average score was 87 points (65-100 points) with 3 excellent, 6 good, and 1 fair. Stability was restored in all patients at the last follow-up. There was no case of nonunion and the average union period was 11.5 weeks. CONCLUSION: This study advocated the additional use of a hinged external fixator in the treatment of complex elbow instability, especially when fixation of fractures and repair of soft tissues were not sufficient. Providing adequate stability and allowing early motion, additional external fixation could improve the functional outcome.

PURPOSE: We evaluated clinical outcomes after treating patients with proximal interphalangeal (PIP) joint fracture-dislocation with dynamic external fixator with which early joint motion can be undertaken to prevent joint stiffness effectively and fixate joints firmly. METHODS: Dynamic external fixators were applied for 20 fracture-dislocation of the PIP joints in 19 patients. The joints involved were 2nd PIP joint in two patients, 3rd PIP joint in three patients, 4th PIP joint in five patients, 5th PIP joint in eight patients. One patient had both 3rd and 4th PIP joint fracture-dislocation. Surgery was performed at least within four weeks. The mean age of the patients was 30.5 years (range, 15-54 years) and the mean follow-up duration was 1.85 years (range, 1-2.3 years) years. All patients were clinically and radiologically assessed on an outpatient basis after being discharged. RESULTS: At the final follow-up, the mean range of motion of PIP joints in flexion was 100.1° (flexion range, 88°-110°), the mean extension lag was 3.0° (extension range, 0°-10°), and the mean visual analogue scale score was 0.8. On anterior-posterior and lateral radiographs, congruity of the joint was satisfactory and 1 mm step off was present in three cases. CONCLUSION: We attained satisfactory clinical outcomes on the recovery of joint movement and joint congruity after treating PIP joint fracture-dislocation injury with dynamic external fixator.

Journal of the Korean Society for Surgery of the Hand 2017;22(2):96-104
PURPOSE: A minimally invasive surgical technique has been introduced to treat carpal tunnel syndrome that causes less pain, minimal scaring, and a rapid recovery. This study was designed to evaluate the safety and effectiveness of the double minimal incision release compared with the open surgery technique. METHODS: A study was performed on 175 cases in 111 patients who were operated on for carpal tunnel syndrome from January 2010 to December 2014. The patients were classified into 2 groups according to the type of surgical technique: 82 cases underwent standard open surgery in group A and 93 cases underwent double minimal incision release in group B. Grip strength and postoperative pain were evaluated 4 and 8 weeks and 6 and 12 months after surgery, and the period of numbness and time needed to resume normal activities were investigated. RESULTS: Group B patients showed better outcomes during the 2 first months after surgery than those of group A patients in numbness, pain, stiffness (p<0.05), less scar pain and tenderness (p<0.001), and shorter time needed to resume normal activities. However, no differences in these parameters were observed between the 2 groups after 6 months (p>0.05). CONCLUSION: Double minimal incision release offered better clinical outcomes until 2 months after surgery compared to the standard open surgery technique and reduced incipient postoperative pain and allowed for earlier resumption of normal activities.

Glyoxalase (GLO) II, which is a component of GLO system and catalyze the conversion of S-lactoyl-glutathione to D-lactate, was purified 1488 fold from rat liver by two steps of Affigel blue and carbobenzoxyglutathione-Sepharose 4B affinity chromatography. The molecular weight of the enzyme was estimated to be 29 kDa which is similar to those from other species. The sequence of N-terminal 9 amino acid residues was determined to be MGIRLLPAT. This was then used to synthesize degenerative primers. cDNA clone was isolated by first synthesizing cDNA from RNA and then PCR amplification. The sequence of cDNA clone was determined by serial sequencing analysis.
