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.

PURPOSE: The purpose of this study was to investigate the perception and satisfaction of cancer patients participating in clinical trials of anticancer drugs and the factors affecting their satisfaction. METHODS: The participants were cancer patients who participated in more than two cycles of clinical trials at a tertiary hospital in Seoul, Korea. Questionnaires were used to assess the perception and satisfaction of clinical trials of anticancer drugs. RESULTS: A total of 106 patients participated. The average perception and satisfaction regarding clinical trials among patients on a 5 point scale was 3.99±0.45 and 4.09±0.55 respectively. There was a significant difference in the correlation among participants' perception and their satisfaction (r =.67, p<.001). Regression analysis revealed that satisfaction was explained by, perception of clinical trials (β =.67, p<.001), participation period 30~59 days (β =.21, p=.009), and participation period over 60 days (β=.20, p=.013). These variables explained 48.7% of the variance of clinical trial satisfaction. CONCLUSION: The results of this study suggest that changes in perceptions of clinical trials are needed to improve satisfaction of anticancer drug clinical trials. This can be used as a basis for improving the quality of clinical trials and education programs for cancer patients participating in clinical trials.

Merkel cell carcinoma (MCC) is an aggressive neuroendocrine carcinoma with a high rate of metastasis. MCC is rarely suspected during clinical examination, thus requiring biopsy to establish a pathologic diagnosis. In addition, MCC sometimes occurs in double primary cancers. Although there have been reviews on double primary cancers, only a few cases involving MCC have been described. Herein, we report a case of a 54-year-old female patient who presented to our clinic with a diagnosis of earlobe MCC following an excisional biopsy performed by another clinic. Further evaluation, including chest imaging, revealed a mass in the lung. The patient underwent a wide excision of the right earlobe, and video-assisted thoracic surgery on the lung. Pathology confirmed MCC in the right earlobe and adenocarcinoma in the lung. The patient underwent postoperative adjuvant chemotherapy followed by radiotherapy. Up to this point, 3 years after the surgery, there has been no evidence of recurrence.

A review of 16 patients diagnosed as having retinal detachment was presented. These cases were patients seen in P.M.C. eye clinic from Sep-73 to Feb-75. 9 of these patients did not have operation for various reasons, but the other 7 were operated by cryopexy, full-thickness scleral buckling with silicone materials, or encircling method with silicone band. The results were as follows; 1) 5 among 7 patients were successful in re-attachment and improvement of visual acuity. 2) No intraocular hemorrhage, the most serious complication due to cryopexy was seen in any of these cases. 3) In one case, the encircling band and implant were removed because small pus pocket and fistula were formed on the bulbar conjunctiva 3 months postoperatively.

PURPOSE: The elbow joint is one of the most stable joints. Dislocation and fracture can occur in elbow joint most commonly next to shoulder joint. Various injuries can occur according to generated mechanism, age of patient and impact. Despite proper treatment, various complications can occur. MATERIALS AND METHODS: We describe etiology and treatment of these complications after elbow trauma such as stiffness, instability and heterotopic ossification. RESULTS AND CONCLUSION: Malunion, nonunion and traumatic arthritis are addressed as a possible complication after fracture around elbow joint.

PURPOSE: This study is to analyze the prevalence of various intra-articular lesions in patients with traumatic recurrent anterior dislocation of shoulder over 40 years and suggest clinical implications for treatment. MATERIALS AND METHODS: We retrospectively studied 16 cases that underwent surgical treatment for recurrent anterior dislocation of shoulder from January 2001 to May 2009. There were 9 males and 7 females, and the mean age was 52.7years. We carried out arthroscopic exam for all patients based on standard protocol, which included labrum, capular lesion, cuff, bony lesions. RESULTS: All 16 cases showed Hill-Sachs lesion, 3 patients (19%) had bony Bankart lesion, 6 patients (38%) had labral tear. Capsular tear were found 15 patients (94%). Twelve (75%) had ruptured supraspinatus and 5 (31%) had subscapularis tear. Only one (6%) had SLAP lesion. CONCLUSION: There was relatively higher incidence of capsular and rotator cuff tears in patients over age 40 years. Preoperative planning to address these lesions is highly recommended.

PURPOSE: Four techniques of intracorporeal lithotripsy are now available: ultrasonic, electrohydraulic, laser and Lithoclast. Among these methods, we studied retrospectively the efficacy and safety of Lithoclast and electrohydraulic lithotripsy(EHL) in the treatment of ureteral stones. MATERIALS AND METHODS: From May 1994 to October 1997, a total of 70 cases with ureteral stones were randomized to either method(39 to Lithoclast and 31 to electrohydraulic lithotripsy). RESULTS: Overall success rates were 84.6%(33 cases among 39cases) for Lithoclast and 83.9%(26 cases among 31 cases) for EHL, so both methods are equivalent in efficacy. The success rates according to location were 85.7% in proximal ureter, 82.4% in middle ureter, 86.7% in distal ureter for Lithoclast and 78.6%, 90.0%, 85.7% for EHL. The success rates according to size were 90.0% in<5mm, 83.3% in 5-9mm, 80.0% in > or =10mm for Lithoclast and 100%, 77.8%, 90.0% for EHL respectively. There were 6 failures with Lithoclast due to upward migration of stone. There were 5 failures with EHL due to upward migration(3 cases), extremely hard consistency(1 case) and poor visual field(1 case). Complications of ureteroscopic stone removal were fever(1 case), ureteral perforation(1 case) with Lithoclast and hematuria(1 case) with EHL, which were treated conservatively. CONCLUSIONS: We have found that efficacy and safety of EHL is as satisfactory as Lithoclast in skilled hands.

Follicular carcinomas are the second most common form of thyroid cancer. There are a few cases regarding initial presentation of a patient with distant metastasis leading to the diagnosis of follicular thyroid carcinoma. Most follicular thyroid carcinomas present as asymptomatic thyroid nodules, but the first sign of the disease is occasionally lymph-node metastases or in rare cases lung or bone metastases. Thirteen percentage of patients had distant metastasis at presentation, and bone metastasis constituted the majority. Vertebrae, pelvis, ribs, and femur were common sites of bone metastasis. Thus, case of metastasis to the femur only from follicular thyroid carcinoma is very rare. We recently experienced a case of follicular thyroid carcinoma with metastasis to the femur who presented with bone pain and pathologic fracture. We present this case with a review of the literature.

A pelvic kidney with a didelphic uterus and a single ectopic ureter into the urethra is an extremely rare finding. We present here a case of a huge ectopic dysplastic kidney with a didelphic uterus and a single urethral ectopic ureter of a 32-year-old women who has been suffering from urinary incontinence. The huge ectopic dysplastic kidney was successfully removed by laparoscopic surgery. The patient became continent after operation.
