PURPOSE: To investigate the clinical features and course of conjunctival malignant melanoma in Korea. METHODS: The medical records of 15 patients, 5 males and 10 females, diagnosed with conjunctival malignant melanoma who had been treated at Severance Hospital from May 1991 to March 2004 were reviewed retrospectively. The clinical parameters of the patients, tumors, and treatment were analyzed for their relation to outcome measures. RESULTS: The mean age at the time of diagnosis was 53.4 years (+/-11.7 years). In all cases, the disease was unilateral and all patients had experienced at least one recurrence. Local lymph node metastasis was found in 3 patients (20%) and the mean time to metastasis was 3.5 years. Systemic metastasis was found in 6 patients (40%) and the mean time to metastasis was 9.3 years. There were 5 cases of tumor-related death (33.3%), 4 of which were attributed to systemic metastasis. The Kaplan-Meier estimates of cumulative survival rate were 90% at 30 months and 56.6% at 70 months. CONCLUSIONS: Although conjunctival malignant melanoma is a rare disease, it is life-threatening and complete tumor excision at an early stage is mandatory, as is additional therapy to prevent local recurrence and systemic metastasis.

PURPOSE: To compare efficacy and safety between early extracorporeal shock wave lithotripsy (eESWL) and deferred ESWL (dESWL) in colic patients with ureteral stones and to investigate whether eESWL can play a critical role in improving treatment outcomes. MATERIALS AND METHODS: A total of 279 patients who underwent ESWL for single radio-opaque ureteral stones of 5 to 20 mm in size were included in this retrospective study. The patients were categorized into two groups according to the time between the onset of colic and ESWL: eESWL (<48 hours, n=153) and dESWL (> or =48 hours, n=126). Success was defined as stone-free status as shown on a plain radiograph within 1 month of the first session. RESULTS: For all patients, the success rate in the eESWL group was significantly higher than that in the dESWL group. The eESWL group required significantly fewer ESWL sessions and less time to achieve stone-free status than did the dESWL group. For 241 patients with stones <10 mm, all treatment outcomes in the former group were superior to those in the latter group, but not for 38 patients with stones sized 10 to 20 mm. The superiority of eESWL over dESWL in the treatment outcomes was more pronounced for proximal ureteral stones than for mid-to-distal ureteral stones. Post-ESWL complication rates were comparable between the two groups. In the multivariate analysis, smaller stone size and a time to ESWL of <48 hours were independent predictors of success. CONCLUSIONS: Our data suggest that eESWL in colic patients with ureteral stones is an effective and safe treatment with accelerated stone clearance.

PURPOSE: The purpose of this study was to assess the effect of quilting suture extent on the latissimus dorsi myocutaneous flap (LDMCF) donor site and the necessity of drainage.METHODS: Clinical data of 136 breast cancer patients, who underwent breast reconstruction using LDMCF between May 2014 and December 2015, were retrospectively reviewed. Patients were divided into three groups. Group A: quilting sutures were performed on half of the LDMCF donor site and a closed suction drain was inserted. Group B: quilting sutures were performed for the entire LDMCF donor site and a closed suction drain was inserted. Group C: quilting sutures were performed for the entire LDMCF donor site and no drain was inserted. The duration of drainage, total drainage, length of hospital stay, number of postoperative aspirations for seroma removal, and total aspirated volume were compared.RESULTS: In the comparison of groups A and B, group B showed better results including the total amount of drained seroma, drain maintenance period, number of aspirations for seroma removal after drainage tube removal, total aspirated seroma, and hospitalization period with statistical significance (P<0.05). In the comparison of groups B and C, group C without drain showed no difference in all other variables except mean total drained seroma volume. Therefore, group C was superior to group A and there was no difference compared to group B with drain, even though the drain was not inserted.CONCLUSION: Total quilting suture at LDMCF donor site can reduce seroma formation and eliminate the need for a drain tube.
