BACKGROUND AND OBJECTIVES: The precise mechanism linking obesity and vascular disease is still unclear. Previous studies have demonstrated that the plasma levels of adiponectin, an adipose-derived hormone, decrease in obese subjects, and that hypoadiponectinemia are associated with ischemic heart disease. In this study, we investigated the determinant factors of plasma adiponectin concentration in healthy premenopausal women. SUBJECTS AND METHODS: We analyzed the plasma adiponectin concentrations in healthy, obese premenopausal women (n=37, BMI> or =25 Kg/m2) and in age-matched, healthy, non-obese premenopausal women (n=23, BMI<25 Kg/m2). The visceral and subcutaneous fat areas were measured by CT scan. RESULTS: Plasma levels of adiponectin in the obese subjects were lower than those in the non-obese subjects (3.24+/-1.08 vs. 4.90+/-2.06 microgram/ml, p<0.01). Significant, univariate, inverse correlations were observed between plasma adiponectin levels and visceral fat areas (r=-0.643, p<0.001), and between adiponectin levels and subcutaneous fat areas (r=-0.407, p<0.01). In univariate analysis, adiponectin was directly related to insulin sensitivity, hsCRP, triglyceride, HDL and LDL cholesterol. In multivariate analysis, visceral fat areas (beta=-0.483, p=0.001) and HDL cholesterol remained significantly related to plasma adiponectin concentrations (beta=0.283, p<0.05). CONCLUSION: These results suggest that HDL cholesterol and visceral fat mass were independently associated with plasma concentrations of adiponectin.

A ruptured distal lenticulostriate artery (LSA) aneurysm is detected occasionally in moyamoya disease (MMD) patients presented with intracerebral hemorrhage. If the aneurysm is detected in hemorrhage site on angiographic evaluation, its obliteration could be considered, because it rebleeds frequently, and is associated with poorer outcome and mortality in MMD related hemorrhage. In this case report, the authors present two MMD cases with ruptured distal LSA aneurysm treated by endovascular embolization.

BACKGROUND AND OBJECTIVES: Percutaneous intervention has become an established technique in the treatment of peripheral arterial obstructive disease. This study was performed to evaluate the procedural success and long-term outcome of percutaneous intervention of the superficial femoral artery (SFA), and to determine the factors that influence the long-term outcome. SUBJECTS AND MEHTODS: Eighty-eight consecutive lesions, in 76 subjects (mean age 65) with chronic lower limb ischemia and SFA obstruction, diagnosed with angiography were included in this study. The angiographic success was defined as residual stenosis <30% and the clinical success as an improvement by at least one clinical category. The clinical patency was defined as an absence of symptom recurrence and target lesion revascularization during the follow up period. The predictors of the outcome were also determined. RESULTS: Balloon angioplasty only was performed in 39 lesions and thrombolysis only in 2, whereas stenting was performed in 47 lesions. Seventy four of the 88 attempts (84%) at recanalization were angiographically successful, while 73 (83%) experienced clinical improvement. The twelve month patency was 67%. Critical ischemia (versus intermittent claudication)(relative risk 4.2, p=0.020) and renal failure (relative risk 4.1, p=0.016) were independent negative predictors of the patency. CONCLUSION: Percutaneous intervention of the SFA yielded a high procedural success rate, with an acceptable long-term outcome. Symptoms of critical ischemia and renal failure were predictive of a low long-term patency.

BACKGROUND: Axillary osmidrosis is characterized by an unpleasant odor, profuse sweating, and in some instances, staining of clothes that may socially and psychologically impair affected individuals. Various types of surgical procedures have been developed for the treatment of axillary osmidrosis. This study was undertaken to evaluate the effectiveness of subcutaneous pulsed neodymium: yttrium-aluminum-garnet (Nd-YAG) laser treatment for the treatment of axillary osmidrosis. METHODS: Twenty-nine patients with axillary osmidrosis were included in this study. Patients were categorized according to the results of an axillary malodor grading system, and a subcutaneous pulsed Nd-YAG laser was applied to all patients. The treatment area for the appropriate distribution of laser energy was determined using the iodine starch test (Minor's test) against a grid pattern composed of 2x2 cm squares. The endpoint of exposure was 300 to 500 J for each grid, depending on the preoperative evaluation results. The results were evaluated by measurement of axillary malodor both pre- and postoperatively using the grading system and iodine starch test. RESULTS: The average follow-up period was 12.8 months. Nineteen patients had a fair-to-good result and ten patients had poor results. The postoperative Minor's test demonstrated that there were remarkable improvements for patients with mild to moderate symptoms. Complications including superficial second degree burns (n=3) were treated in a conservative manner. A deep second degree burn (n=1) was treated by a surgical procedure. CONCLUSIONS: Subcutaneous pulsed Nd-YAG laser has many advantages and is an effective noninvasive treatment for mild to moderate axillary osmidrosis.

PURPOSE: The shape and location, the amount of the wound and the characteristics of the remaining tissues are known to influence wound contraction. The previous studies using small animals have not been an appropriate model because the wound healing mechanisms and skin structures are different from those of the human. The purpose of this study is to evaluate wound contraction according to the shape and location of the wound using a Micropig(R). METHODS: Four Micropigs(R)(Medikinetics, Pyeongtaek, Korea) that were 10 months of age weighed 25kg were used. Full thickness skin defects were made by clearing all the tissues above the fascial layer in the shape of square, a regular triangle and a circle of 9cm2 each on the back around the spine. Eight wounds were created on the back of each pig, 50mm apart from each other. The randomly chosen wound shapes included 11 squares, 11 regular triangles, and 10 circles. Wound dressing was done every other day with polyurethane foam. The wound size was measured using a Visitrak Digital(R)(Smith & Nephew, Hull, UK) on every other day after surgery from day 2 to day 28. A biopsy was performed on day 3, and 1, 2, 3 and 4 weeks to investigate the degree of acute and chronic inflammation, the number of microvesssel and myofibroblast density using H & E stain and immunohistochemistry. The wound contraction rate was calculated to figure out the differences among each of the shapes and the locations. RESULTS: The ultimate shape of the circle wound was oval, and that of the regular triangle and square were stellate. The maximum contraction rate was obtained on 8 to 10 days for all the shapes, which corresponds with the immunohistochemical finding that myofibroblast increases in the earlier 2 weeks whereas it decreases in the later 2 weeks. Epithelialization was seen in the wound margin on day 7 and afterwards. The final wound contraction rates were highest for the regular triangle shapes; however, there were no statistically significant differences. The wound contraction rates by locations showed statistically significant differences. The wound in the cephalic area presented more contractions than that of the wounds in the caudal area. CONCLUSION: The location of a wound is more important factor than the wound shape in wound contraction.

OBJECTIVE: The authors evaluated the feasibility and targeting accuracy of CT fluoroscopy (CTF)-guided catheter placement and aspiration of intracerebral hematoma (ICH)s. MATERIALS AND METHODS: Nine patients (mean age, 63.3 +/- 15.3 years) were treated by CTF-guided hematoma aspiration under local anesthesia. The targeting errors in the lesion center, volume of the aspirated hematoma, accuracy of the final catheter position, procedure time, and clinical outcomes were evaluated. RESULTS: All catheters were successfully placed in the center of the hematoma. The mean volume of the aspirated hematoma was 20.6 +/- 8.8 mL (pre-treatment, 44.7 +/- 20.1 mL; post-treatment, 24.1 +/- 13.8 mL). The average procedure time was 25.1 minutes (range, 18-32 minutes). In one case with a scanty residual hematoma, the catheter was removed at the end of the procedure. In the remaining eight cases, the catheter was left in the residual hematoma for drainage and all catheter tips were accurately located in the final position. There were no procedure-related complications, including rebleeding and infection. CONCLUSION: CTF-guided ICH aspiration is a feasible, quick, and accurate procedure which could substitute for stereotactic methods. The accurate catheter position provided by real-time observation enables an effective aspiration and drainage of hematomas.

BACKGROUND AND OBJECTIVES: Previous studies have demonstrated that adipokines can have positive and/or negative effects on vascular function. In this study, we attempted to characterize the association of adipokines with endothelium-dependent vasodilation in healthy premenopausal women. SUBJECTS AND METHODS: Noninvasive pulse wave analysis coupled with provocative pharmacological testing with salbutamol was used to measure endothelium-dependent vasodilation in 60 healthy premenopausal women [37 obese women; body mass index (BMI) > or = 25 kg/m2, 23 age-matched non-obese women; BMI<25 kg/m2]. The lipid profile, fasting insulin, glucose, and C-reactive protein (CRP) concentrations in each patient were assessed via standard laboratory techniques, and plasma concentrations of various adipokines, such as adiponectin, leptin, resistin and TNF-alpha, were measured via enzyme immunoassays. RESULTS: In the obese group, higher leptin concentrations were significantly associated with impairments in endothelium-dependent vasodilation (r=-0.371, p=0.005). This association remained significant, even after adjustment for other risk factors (beta=-0.39, p=0.006). However, we determined that there was no significant correlation between endothelium-dependent vasodilation and these variables in the obese group and the control group. CONSLUSION: Increased plasma concentration of leptin was associated with impairment in endothelial function in obese premenopausal women, regardless of the metabolic and inflammatory disturbances associated with obesity.

Although myocardial stunning occurs in coronary artery disease, it has rarely been reported with hyperthyroidism. A 72-year-old woman presented with general weakness, shortness of breath and febrile sensation of 10 days duration. The serum thyroid hormone level was elevated. Serial EKGs showed significant ST elevation suggesting transmural ischemia, but coronary angiography was not significant. Echocardiography showed regional wall motion abnormality of apical hypokinesia, which was improved after medication for hyperthyroidism. We report this case as an example of myocardial stunning associated with hyperthyroidism.
