BACKGROUND: It is well known that renal TGFbeta expression is related to the development of diabetic nephropathy. Alpha-lipoic acid (ALA), a potent antioxidant and cofactor of mitochondrial respiratory enzymes, can improve the insulin resistance and the vascular endothelial dysfunction, and suppresses the development of diabetic vascular complications. This study was undertaken to investigate whether ALA could reduce urinary protein excretion and renal TGFbeta protein expression in obese type 2 diabetes mellitus animal model, Otsuka Long-Evans Tokushima Fatty (OLETF) rat. METHODS: Obese 30 male OLETF rats were randomly divided to 3 groups at the age of 30 weeks. The rats in the Control group fed normal rat chow while the rats in the ALA group were fed with rat chow containing ALA (0.5% of food weight). Ten rats in the Pair-fed group were fed with normal rat chow, but were given the same amount of food as consumed by the ALA group. During 5 weeks of ALA feeding, food intake and body weight were checked in metabolic chamber. Blood glucose levels, HbA1c and urinary protein excretion were measured at 30 weeks and 35 weeks of age, and renal TGFbeta protein expression at 35 weeks of age was measured by Western blot and represented by relative unit (RU). Immunohistochemical staining for TGFbeta protein in renal tissue was also examined at 35 weeks of age. RESULTS: Food intake, body weight, blood glucose levels, HbA1c and urinary protein excretion among the Control, ALA and Pair-fed groups at 30 weeks of age were not different. At 35 weeks of age, food intake was significantly decreased in the ALA group than the Control group (Control group vs. ALA group, 27.7 +/- 1.1 g/day vs. 22.4 +/- 1.4 g/day, P < 0.001), and body weight was significantly decreased in the ALA group than the Control and Pair-fed groups (Control group: 694.4 +/- 10.3 g, ALA group: 600.4 +/- 7.4 g, Pair-fed group: 685.4 +/- 11.6 g, P < 0.001). Blood glucose levels were significantly decreased in the ALA group than the Control and Pair-fed groups (Control group: 157.7 +/- 4.6 mg/dL, ALA group: 130.7 +/- 4.8 mg/dL, Pair-fed group: 153.7 +/- 3.3 mg/dL, P < 0.001) although blood glucose levels from 30 weeks to 34 weeks of age and HbA1c at 35 weeks of age were not different among the groups. Urinary protein excretion and renal TGFbeta protein expression were significantly decreased in the ALA group than the Control and Pair-fed groups (urinary protein excretion, Control group: 5.033 +/- 0.254 mg/mgCr, ALA group: 3.633 +/- 0.303 mg/mgCr, Pair-fed group: 4.977 +/- 0.339 mg/mgCr, P < 0.001; renal TGFbeta protein expression, Control group: 7.09 +/- 0.17 RU, ALA group: 4.14 +/- 0.26 RU, Pair-fed group: 7.00 +/- 0.29 RU, P < 0.001). In the ALA group at 35 weeks of age, urinary protein excretion and renal TGFbeta protein expression were positively related in the Control, ALA and Pair-fed groups (Control group, r = 0.847, P = 0.002; ALA group, r = 0.954, P < 0.001; Pair-fed group, r = 0.858, P = 0.002). TGFbeta staining in glomeruli was observed in all groups but was decreased in the ALA group at 35 weeks of age. CONCLUSION: These results suggest that ALA may prevent the increase of food intake, body weight, blood glucose, urinary protein excretion and renal TGFbeta protein expression in obese type 2 diabetic rat model. The effect of ALA on diabetic nephropathy presented as proteinuria and renal TGFbeta expression in diabetic patients needs to be further clarified.

PURPOSE: To correlate SOhographic and pathologic findings of gallbladder adenoma, and to evaluate the clinical significance of sonographic findings. MATERIALS AND METHODS: Ultrasound findings of twenty gallbladder adenomas were retrospectively reviewed to evaluate the size, shape and echogenicity of the adenoma, and was correlated with the pathological finding. RESULTS: Among 14 patients, 11 patients had single lesion and 3 patients had multiple lesions. Three patients showed 2, 3 and 4 adenomas, respectively. Nine of 20 lesions showed focal dysplasia pathologically. Among the nine adenomas with dysplasia, two adenomas showed focal cancerous change. The nine adenomas showing focal dysplasia measured 25.6mm (14-35mm) in mean diameter, while the mean diameter of adenomas without dysplasia was 8.7 mm (3-13mm). The echogenicity of adenoma with focal dysplasia were hyperechoic in 8, isoechoic in 1. The echogenicity of adenomas without dysplasia were hyperechoic in 7, isoechoic in 4. Sessile(7/9) and papillary shape(6/9) were predominant in adenoma with dysplasia, but smooth shape(8/11) and stalked type(9/11) were predominant in adenoma without dysplasia. Two adenomas with focal cancerous change showed histological transition from cancer to dysplasia and to adenomatous tissue. In adenoma with dysplasia, the diameter more than 14 mm on sonography was statistically significant (p<0. 005). Also age of patient was significantly different between the two groups (p<0.01), while echogenicity and associated stone were not statistically significant. CONCLUSION: As gallbladder adenoma more than 14ram in diameter on US is suggestive of dysplasia on pathology, so, close follow up US or surgery is recommended.

BACKGROUND: Epidermal cysts are commonly occurring masses usually less than 5 cm in diameter, but in predisposed patients, epidermal cysts can grow relatively large due to chronic infection. METHODS: From June 2002 to July 2010, 17 patients received 19 regional perforator-based island flaps to cover defects due to the excision of large epidermal cysts (diameter >5 cm) in the buttocks. Eight patients had diabetes, and seven had rheumatoid arthritis. The pedicles were not fully isolated to prevent spasms or twisting. RESULTS: All the flaps survived completely, except for one case with partial necrosis of the flap, which necessitated another perforator-based island flap for coverage. There were two cases of wound dehiscence, which were re-closed after meticulous debridement. There were no recurrences of the masses during follow-up periods of 8.1 months (range, 6-12 months). CONCLUSIONS: In patients with large epidermal cysts and underlying medical disorders, regional perforator-based island flaps can be the solution to coverage of the defects after excision.

Metastases from colorectal cancer can occur by either lymphatic or hematogenous spread, and the sites most commonly involved are the liver and lung. Although skeletal muscle comprises a considerable portion of body mass and receives abundant blood supply, it is one of the most unusual sites of metastasis from any malignancies. We report a case of skeletal muscle metastasis from colorectal cancer. An 83-year-old female patient presented with a painful mass in the right posterior thigh. She had already undergone low anterior resection and right lobectomy of liver for rectal cancer with liver metastasis (T2N1M1) about 4 years ago. Although a follow-up computed tomography scan showed a metastatic solitary pulmonary nodule in the left lobe 2 years after the primary operation, she refused further aggressive treatment. Magnetic resonance imaging showed a localized mass in the semimembranosus muscle of the right thigh, and fine-needle aspiration cytology demonstrated clusters of atypical cells compatible with adenocarcinoma. The patient underwent excision of the painful mass located in the right semimembranosus muscle. Histologically, the thigh mass proved to be adenocarcinoma identical to the primary lesion. The patient died of heart failure on the 2nd postoperative day.

PURPOSE: The management of central venous catheters (CVCs) and catheter thrombosis vary among centers, and the efficacy of the methods of management of catheter thrombosis in CVCs is rarely reported. We investigated the efficacy of bedside thrombolysis with urokinase for the management of catheter thrombosis. MATERIALS AND METHODS: We retrospectively reviewed data from patients who had undergone CVC insertion by a single surgeon in a single center between April 2012 and June 2014. We used a protocol for the management of CVCs and when catheter thrombosis was confirmed, 5,000 U urokinase was infused into the catheter. RESULTS: A total of 137 CVCs were inserted in 126 patients. The most common catheter-related complication was thrombosis (12, 8.8%) followed by infection (8, 5.8%). Nine of the 12 patients (75%) with catheter thrombosis were recanalized successfully with urokinase. The rate of CVC recanalization was higher in the peripherally inserted central catheter (PICC) group (87.5%) than the chemoport group (50%). Reintervention for catheter-related thrombosis was needed in only 2.2% of patients when thrombolytic therapy using urokinase was applied. Age <60 years (P=0.035), PICC group (P=0.037) and location of the catheter tip above the superior vena cava (P=0.044) were confirmed as independent risk factors for catheter thrombosis. CONCLUSION: Thrombolysis therapy using urokinase could successfully manage CVC thrombosis. Reintervention was rarely needed when a protocol using urokinase was applied for the management of CVC thromboses.

PURPOSE: Pneumatosis intestinalis (PI) is increasingly being detected in recent years with the more frequent use of computerized tomography (CT). The present study was performed to evaluate the clinico-radiologic characteristic presentation of PI and to determine the prognostic factors for mortality. METHODS: Fifteen patients who were diagnosed with PI on CT between June 2000 and May 2010 were retrospectively reviewed. Age, sex, location of PI, presence of portal vein gas, time to diagnosis, American Society of Anesthesiologists (ASA) classification, Acute Physiology And Chronic Health Evaluation II (APACHE II), acidosis, shock, and other associated findings were analyzed for their association with outcome. RESULTS: Fifteen patients (7 males and 8 females, average age, 60.3 years) were diagnosed with PI. Mortality rate was 47% (7 patients). The mortality rate in patients with septic shock, APACHE II score (18), acidosis (pH<7.36) were all 100%, 87%, 100%, respectively (P<0.05). Age, sex, location of PI, portal vein gas, time to diagnosis, ASA classification, associated findings did not show statistical difference. CONCLUSION: Shock, APACHE II score (18) and acidosis were associated with high mortality in patients with PI. So, more intensive management and interest are recommended in patients with shock, APACHE II score (18), and acidosis due to PI.
