ABSTRACT
A mucocele is a cystic dilatation of the vermiform appendix that contains mucous material. The symptoms associated with it are not specific and the diagnosis is seldom made prior to surgery. The reported prevalence in appendectomy specimens procured during surgery is 0.2-0.3%. Recently, we experienced a case of patient with appendiceal mucocele detected by colonoscopic examination. This case did not show typical colonoscopic features of a mucocele, demonstrating protrusion of mucin, in the absence of a smooth mound with normal overlying mucosa surrounding the appendiceal orifice. The case involved a 64-year-old woman who underwent a colonoscopy. An abdominopelvic computed tomography scan suggested a normal appendix. Subsequently, we performed an appendectomy. The pathologic finding was a low-grade appendiceal mucinous neoplasm.

ABSTRACT
A parastomal hernia is the most common surgical complication following stoma formation. As the field of laparoscopic surgery advances, different laparoscopic approaches to repair of parastomal hernias have been developed. Recently, the Sugarbaker technique has been reported to have lower recurrence rates compared to keyhole techniques. As far as we know, the Sugarbaker technique has not yet been performed in Korea. We herein present a case report of perhaps the first laparoscopic parastomal hernia repair with a modified Sugarbaker technique to be successfully carried out in Korea. A 79-year-old woman, who underwent an abdominoperineal resection for an adenocarcinoma of the rectum 9 years ago, presented with a large parastomal and incisional hernias, and was treated with a laparoscopic repair with a modified Sugarbaker technique. Six months after surgery, follow-up with the patient has shown no evidence of recurrence.

PURPOSE: Transforming growth factor (TGF)-beta1 and Hypoxia inducible factor (HIF)-1alpha are renal fibrogenetic cytokines involved with the fibrosis of renal allograft. The aim of this study was to investigate TGF-beta1 and HIF-1alpha in renal allograft patients. METHODS: Between January, 1995 and February, 2005, we performed 72 renal allograft biopsies from 61 recipients. Immunohistochemical studies were performed with a immunoperoxidase technique using the primary antibody, rabbit anti-human TGF-beta1 polyclonal antibody (C-teminus, 1:1,000, Santa-Cruz Biotechnology, Santa Cruz, CA, USA) and mouse anti-human HIF-1alpha monoclonal antibody (clone H1alpha 67-sup, 1:1,000, Novus Biological Inc., Littleton, CO, USA). RESULTS: Tubular and interstitial TGF-beta1 expressions in CAN were higher than other groups, showing significant differences (P<0.05). HIF-1alpha expression in CAN was much higher than other groups (P<0.05). The glomerular TGF-beta1 expression of the heavy proteinuria (2.5 gm/day <) group was significantly higher than the low proteinuria group (<1.0 gm/day) (P<0.05). The tubular TGF-beta1 expression of the graft functioning group was significantly lower than the graft loss group (P<0.05). CONCLUSION: In conclusion, HIF-1alpha expression in renal allograft strongly suggests the development of CAN as well as tubular or interstitial TGF-beta1 expression. TGF-beta1 expression in the glomerulus shows significant correlation with the amount of 24 hours urine protein. The tubular TGF-beta1 expression has strong correlation with graft survival.
