The cystic lesions within the knee joint are rare, contrary to those located around the knee. They usually are eniscal or ganglion cyst, reported in association with the joint capsule of the knee or the menisci and close to the peroneal tendons. The intraarticular ganglion cyst arising from the cruciate ligaments are rare and cause pain, effusion and limitation of the knee joint. We report (he case of a patient with right knee joint pain caused hy an intraarticular ganglion cyst arising from the posterior cruciate ligament with review of reference.

As the productive activities have vastly increased following industrialization and urbanization in the modem society, the resulting high mobility of people and goods have caused a sharp increase in the accidents in the work places as well as traffic accidents. In particular, deaths caused by injuries are generally concentrated in the economically active young peoples, producing incalculable losses to the society and nation as a whole. Advanced nations with superior medical care systems have succeeded in reducing incidents of such deaths by operating trauma centers. Especially noteworthy is the case of the United States where such specialized trauma centers have greatly contributed to reducing deaths from injuries in the non-urban areas with less access to medical facilities. At present Korea has no medical centers specializing in injuries. In large cities, the injuries are being treated tertiary medical facilities while in the provinces they are referred to small and medium-sized hospitals that constitute secondary medical facilities. Currently in Korea the Trauma patients are treated at general hospitals that consist of 726 secondary medical facilities and 40 tertiary medical centers nationwide. The secondary medical facilities which tend to take most responsibility for the treatment of trauma are generally deficient in medical staff and facilities (including operating and intensive care facilities). Despite such deficiency and limitations, no regulations exist regarding treatment or transportation of trauma patients. This article reports the outcome of a comparative analysis of the results of trauma treatments among different types of medical facilities based on objective data in the hope that such study would facilitate a comparison with the treatment systems of advanced countries and thereby contribute to a precise formulation of problems that must be addressed in this area.

We encountered a case of Sweet's syndrome associated with myelodysplastic syndrome in a 60-year-old woman. The clinical presentation strongly suggested Sweet's syndrome. A skin biopsy specimen taken from her skin lesion on the leg showed an infiltration of numerous neutrophils in the subcutis instead of the dermis which is the main area of neutrophilic infiltration in Sweet's syndrome. Among infiltrating cells, many neutrophils(8%) showed nuclear segmentation anomalies, that is, hyposegmentation(pseudo-Pelger-Huet anomaly) or hypersegmentation. Peripheral blood neutrophils had similar anomalies. This subcutaneous variant of Sweet's syndrome, Sweet's panniculitis, is rare and nuclear segmentation anomalies of neutrophils are probably a good clue to underlying myelodysplastic syndrome.

BACKGROUND: Although pulmonary artery catheters are useful to monitor hydration, these devices may be associated with severe morbidity and are not routinely used in kidney transplantation. A central venous pressure (CVP) catheter is preferred rather than a pulmonary artery catheter. Noninvasive continuous blood pressure monitors may substitute for intraarterial catheters, thereby preserving the radial artery in kidney transplantation patients should it be needed later to create an arteriovenous fistula. If there is a relationship between central venous and radial arterial blood for acid-base (pH, BE, HCO3(-)), we can use the blood sample from a CVP catheter instead of arterial blood from aradial artery catheter for testing acid-base and it can help patients. METHODS: A central venous catheter and radial artery catheter was inserted in 67 patients while undergoing kidney transplantation. To assess arteriovenous differences in acid-base status at operation start, before reperfusion of the transplanted kidney, after reperfusion, we measured the pH, BE and HCO3(-) simultaneously from the arterial and central venous circulation. RESULTS: Aacid-base using arterial and central venous samples at operation start, before reperfusion and after reperfusionb was evaluated. We found the relationship as follows: pH between arterial (pHa) and central venous blood (pHcv) in each: linear regression equation; pHcv = 0.668 + (0.906 X pHa), pHcv = 0.225 + (0.965 X pHa), pHcv = 0.646 + (0.908 X pHa), determination coefficient; 0.908, 0.926, 0.888, P values < 0.001 in each period. Base excess (BE) between BEa and BEcv in each period: linear regression equation; BEcv = 0.483 + (0.952 X BEa), BEcv = 0.032 + (0.939 X BEa), BEcv = 0.008 + (0.954 X BEa), determination coefficient; 0.844, 0.954, 0.962 P values < 0.001 in each period. HCO3(-) concentration between HCO3(-)a and HCO3(-)cv in each period: linear regression equation; HCO3(-)cv = 2.434 + (0.937 X HCO3(-)a), HCO3(-)cv = 2.093 + (0.942 X HCO3(-)a), HCO3(-)cv = 1.755 + (0.954 X HCO3 a), determination coefficient; 0.950, 0.925, 0.932 P values < 0.001 in each period. CONCLUSIONS: The acid base status of arterial blood is similar to that of central venous blood. Central venous blood gas values (pH, BE, HCO3(-)) may be an acceptable alternative to arterial blood gas values in kidney transplantation patients.

To investigate the chemomyectomy effect of doxorubicin on extraocular muscle, we injected 0.05ml doxorubicin into right superior rectus muscle for the experimental group and 0.05ml balanced salt solution into left superior rectus muscle for the control group of 12 rabbits. The gross and histologic examinations were done at 1, 2, 4 and 8 weeks after the injection. The results were as follows; 1. On gross examination, thickness of muscle mass at injection site was decreased with the time in the experimental group, and neither conjunctival adhesion and symblepharon nor scleral necrosis was found in both groups. 2. On microscopic examination, the degree of muscle fragmentation and necrosis was increased with the lapse of time in the experimental group. But there was no observable change with the lapse of time in the control group. These results suggested that doxorubicin was such a selective myotoxin to extraocular muscles that it could be used for nonsurgical treatment of chronic paralytic and restricted form of strabismus.

PURPOSE: The purpose of the study was to investigate five cases with chronic Achilles tendon rupture that occurred after steroid injections. MATERIALS AND METHODS: In our hospital, we experienced five cases of chronic Achilles tendon rupture from September 2010 to March 2012. All patients had got steroid injection for Achilles tendinitis at the other hospitals, and their heel pain was aggravated when they visited our outpatient department. After treatment, signs and symptoms of Achilles tendon rupture were developed and the diagnosis was confirmed by ultrasonography or magnetic resonance imaging (MRI). Surgical treatment was done for Achilles tendon rupture. RESULTS: There was difference between intra-operative findings of Achilles tendon rupture and usual chronic Achilles tendon rupture. Unlike usual findings of chronic Achilles tendon rupture whose scar tissue or tissue attenuation are found around the defect area of Achilles tendon, there were partial necrosis of tendon severe adhesion with surrounding tissue, extensive defect and longitudinal rupture on ruptured area. Also, severe inflammation of paratenon, granulation and fibrinoid deposit were found on biopsy findings in four cases. CONCLUSION: Based on review of data about relative risk and benefit of local corticosteroid injection to inflammatory lesion in Achilles tendon, it requires more attention to Achilles tendon rupture following local corticosteroid injection.

Resection of hepatic tumors located near the confluence of hepatic vein or invading retrohepatic vena cava has become technically feasible and relatively safe with the introduction of veno-venous bypass. Hepatic vascular exclusion(HVE) with the aid of veno-venous bypass using centrifugal pump enables safe resection and reconstruction of vena cava without hemodynamic instability, compared to conventional HVE. The authors report a case of a successful en bloc resection of right lobe and caudate process of liver, right adrenal, right kidney, and retrohepatic vena cava, in order to extirpate huge retroperitoneal tumor, with the aid of veno-venous bypass using centrifugal pump. Pathologic diagnosis revealed B cell type non Hodgkin's lymphoma arising from adrenal gland. After resection, caval defect was reconstructed with Dacron graft. Patency of reconstructed cava could be observed at five months postoperatively.

STATEMENT OF PROBLEM: The failure of adhesion between the resilient denture liner and the denture base is a serious problem in clinic. PURPOSE: The PURPOSE of this study was to evaluate the effect of denture base resin surface pretreatments (mechanical and/or chemical) on the tensile bond strength between a resilient liner and processed denture resin. MATERIAL AND METHOD: Acrylic-based resilient liners (Soft liner; GC co., Japan & Coe-Soft; GC America Inc. USA) and silicone-based resilient liners (Mucosoft; Parkell Inc., USA & Dentusil; Bosworth co., USA) were used. Specimens in each soft lining material were divided two groups with or without mechanical pretreatment. Each denture base specimen received 1 of 4 chemical pretreatments including: (1) no treatment, (2) 30-s acetone treatment, (3) 15-s methylene chloride treatment, (4) 180-s methyl methacrylate treatment. All specimens were thermocycled and placed under tension until failure in a universal testing machine. RESULTS: 1. Silicone-based resilient liners exhibited significantly higher tensile bond strengths than acrylicbased resilient liners (P<.05). 2. Grinding the denture base resin improved tensile bond strengths of silicone-based resilient liners, but reduced tensile bond strengths of acrylic-based resilient liners (P<.05). 3. In acrylic-based resilient liners, treating with acetone significantly increased the bond strength of Soft liner and treating with methyl methacrylate significantly increased the bond strength of Coe-Soft (P<.05). However they were not effective compared to silicone-based resilient liner. 4. In silicone-based resilient liners, treating with all chemical etchants significantly increased the bond strength of Mucosoft to denture base, and treating with methylene chloride and methyl methacrylate increased the bond strength of Dentusil to denture base (P<.05). CONCLUSION: Although chemical and mechanical pretreatments were not effective on tensile bond strength of acrylic-based resilent liner to denture base, treating the denture base resin surface with appropriate chemical etchants after mechanical pretreatment significantly increased the tensile bond strength of silicone-based resilient liner to denture base.
