The developement of squamous cell carcinoma from the draining sinus of chronic osteomyelitis has long been recognized as a rare and late complication. The mode of developement of carcinoma at the site of chronic osteomyelitis is not well understood. This, however, is chiefly a disease of middle aged men, and tibia is the most common site. There are two types in this carcinoma; superficial and deep types. In the superficial type obvious presence of fungaiing growth makes diagnosis simple and easily confirmed by biopsy. In the deep type the diagnosis is difficult clinically, but the features most frequently described are an increase in pain and discharge with swelling and hemorrhage. Amputation at the adequate level is the treatment of choice. Three cases of the disease involving one left femur, and two left tibiae are reported with review of literature.

PURPOSE: Since the introduction of short vein bypass (SVB), many have reported its feasibility when long vein bypass (LVB) cannot be performed due to limited vein conduit. However, the presence of inflow-vessel disease may affect graft patency and thus require endovascular treatment prior to surgery. Our study aims to analyze the results between SVB and LVB. MATERIALS AND METHODS: From 2009 to 2013, 27 bypass procedures were reviewed retrospectively. Outcomes such as patency rate, postoperative ankle brachial index (ABI) and limb salvage rate between SVB and LVB were compared. Wound healing time and primary patency rate were analyzed and the former was also analyzed according to the respective angiosome and revascularization type. RESULTS: There were 11 males and 16 females and the mean age was 66.6+/-12.3 years. Twenty four patients had TransAtlantic Inter-Society Consensus (TASC) D and 3 patients had TASC C lesions below knee. The 1-year cumulative patency rate between SVB and LVB were 63% and 66%, P=0.627. The limb salvage rate (100% vs. 73%; P=0.280) and postoperative ABI (0.592 vs. 0.508; P=0.620) were higher in the SVB group than in the LVB group, although the differences were not significant. There was no difference in wound healing time by angiosomal revascularization type. In situ vein graft showed higher patency rate than reversed greater saphenous vein (75% vs. 61%; P=0.00) CONCLUSION: The results of SVB were similar to those of LVB. SVB is feasible in the setting of limited conduit availability, in combination with endovascular treatment in the presence of proximal lesions.

Isolated rat thoracic aorta which is pharmacologically precontracted by phenylephrine induces photorelaxation when exposed to long wave length UV-light. The aim of the present study was to characterize the mechanism of UV-light induced by photorelaxation in the rat aorta. 1. UV light relaxed both endothelium-intact and -denuded rat aortic rings contracted by phenylephrine. The magnitude of relaxation on UV light was dependent on the exposure time and slightly greatly in endothelium-denuded rings than in endothelium-intact preparations. 2. L-NAME (10 nM-100 uM) but not D-NAME completely inhibited the photorelaxation in a concentration dependent manner. 3. The UV-induced relaxation was inhibited by methylene blue (1 -100 uM), and verapamil (100 nM), and removal of extracellular Ca2+. In contrast, UV-light induced photorelaxation was potentiated by N(w)-nitro-Larginine (L-NOARG) treatment. 4. In immunocytochemical analysis of UV-light induced iNOS and eNOS expression in rat aortas, at which expression levels were increased in a time-dependent manner on UV-irradiation in aortic endothelium and smooth muscle, respectively. These results suggest that UV light-induced photorelaxation may be due to nitric oxide from exogenously administered L-arginine as well as endogenous nitric oxide donors such as amino acid and arginine derivatives. Additional suggestion is that UV light stimulates the expression of nitric oxide synthases, and its activity for nitric oxide generation is dependent on cytosolic Ca2+ originated from extracellular space.

Aggressive angiomyxoma is a rare, locally aggressive tumor and occurs exclusively in the pelvic and perineal regions of women. But this tumor can occur in men, and the ratio of man to woman is about 1:6. We report a case of aggressive angiomyxoma of the scrotum in a 75-year-old man. The resected mass measured 23 21 10 cm and weighed 1,150 g, and was covered with thick but intact scrotal skin. The cut surface of the mass showed pale yellow to grayish white loose and edematous fibrous tissue with focal cystic degeneration. Microscopically, the mass was composed of loosely arranged bland-looking spindle or stellate cells and variable sized blood vessels with thickened and hyalinized wall. The spindle cells were strong positive for vimentin, focal, weak positive for desmin and smooth muscle actin but negative for S-100 protein. The spindle cells were also positive for estrogen and progesterone receptors.
