Purpose: Anatomical repair of massive rotator cuff tear has been technically challenging because of medial retraction, muscle atrophy and fatty degeneration. Among several treatment options for massive rotator cuff tear, we reviewed rotator cuff repairs and investigated modalities for improvement of clinical outcomes, decreasing the re-tear rate, and increasing healing. Materials and Methods: Patient-related factors and rotator cuff-related factors were the two major groups of factors we considered when choosing a treatment plan. Results: Mobilization of a massive rotator cuff tear was increased by soft tissue release and by the interval slide technique. After meticulous soft tissue release, anatomical repair could be achieved. If the injury was not amenable to anatomical repair, alternative treatment options such as partial repair, the margin convergence technique and augmentation with a tenotomized biceps tendon were considered. Many reports of massive rotator cuff repair demonstrated satisfactory clinical outcomes, decreased pain, recovery of shoulder functions, and increases in muscle strength. However, the re-tear rate had been reported to be relatively high in long-term follow-up. Conclusion: Despite a high re-tear rate after massive rotator cuff repair, a better understanding of the pathogenesis, progression and clinical symptoms of massive rotator cuff tear and improved surgical materials and techniques will lead to satisfactory clinical outcomes.

Purpose: Surgical treatment of massive rotator cuff tear is challenging and there are various surgical options. The purpose of this article is to describe arthroplasty for the treatment of massive rotator cuff tear. Materials and Methods: We reviewed all publications that focused on and/or mentioned arthroplasty as a treatment option for massive rotator cuff tear. Results: Arthroplasty can be used as primary treatment and represents a salvage option for irreparable rotator cuff tear. Hemi-arthroplasty can provide satisfactory results by Neer's limited goals criteria in patients with intact coracoacromial arch. In addition, reverse total shoulder arthroplasty can be a salvage option for pain relief and restoration of active flexion in elderly patients with pseudoparalysis. Conclusion: In patients with massive rotator cuff tear, proper selection of arthroplasty can provide pain relief and restoration of functional range of motion in shoulder joints.

Synovial sarcomas of the hand are rare. It should be treated with wide resection. In the cases of soft tissue sarcomas of the hand, functional reconstruction must be considered. We report 46-year-old male patient with synovial sarcoma of the right thenar muscle which was treated with unplanned intralesional resection at outside hospital, that has been treated with wide resection including trapezium and first metacarapl bone then, reconstructed with nonvascularized fibular graft and anterolateral thigh free flap.

The purpose of this study was typing the plasmid mediated extended spectrum ${\beta}-lactamases$ produced by enteric bacteria isolated from rivers in Pusan. Six strains of Eschericha coli and fifteen strains of Klebsiella pneumoniae transferred their plasmid mediated extended spectrum ${\beta}-lactamase$ genes to the recipient strain Eschericha coli J53 $Azid^{R}$. The plasmid mediated extended spectrum ${\beta}-lactamase$ genes were sequenced directly after PCR and the types were determined by the BCM Search Launcher and GenBank nucleotid database. Determined types of the plasmid mediated extended spectrum ${\beta}-lactamases$ were TEM-52 and SHV-12. TEM-52 was isolated from both Escherichia coli and Klebsiella pneumoniae. However SHV-12 was isolated from Klebsiella pneumoniae only. The results indicated that the plasmid mediated extended spectrum ${\beta}-lactamase$ producing bacteria spreded over the area of clinical to the nature in Korea.

Purpose: The purpose of this study was to determine the correlation between the radiographic and clinical findings of massive rotator cuff tears. Materials and Methods: Forty-five diagnosed cases (35 patients) of massive rotator cuff tears were investigated in this study. Grade of arthritis in the massive rotator cuff tears was classified based on plain radiographs using the method of Hamada et al.. And we clinically evaluated cases using the UCLA scoring system. Results: No statistically significant correlation ($r_s$=0.220, p=0.151) was found between arthritis grades in massive rotator cuff tears and clinical features. Dominant arm involvement appeared to be related to a higher rate of surgical treatment and a lower UCLA score. Conclusion: In massive rotator cuff tear patients, radiographic findings of arthritis may not always correspond to clinical features relevant in daily life. Therefore, we suggest that treatment strategies should be carefully considered when considering treatment modalities.

우리나라는 고생대의 조선계층에 석회암이 분포하는데 이 석회암지대는 탄산가스를 포함하는 우수에 용식되어 카르스트 지형이 널리 분포하고 있다. 석회암은 자연상태에서는 광범위하게 분포하는 퇴적암이므로 카르스트 지형도 광범위하게 분포할 것 같지만, 실제는 매우 제한적인 분포를 보인다. 세계적으로 유명한 석회암 카르스트 지형 분포지는 프랑스의 코스지방을 비롯하여, 스페인의 안다루시아지방, 자메이카, 쿠바 서부, 중국의 화남지방, 버어마 일부, 일본의 아키요시다이 등이다. (중략)
