Endovascular treatment of isolated bilateral common iliac artery aneurysm (CIAA) requires salvage of at least one internal iliac artery to prevent complications such as ischemic buttock claudication. We treated a case of bilateral CIAAs using an internal iliac branched stent graft. We report a case of a 58-year-old man who presented with bilateral CIAAs. The left internal iliac artery was occluded with coil embolization. The right internal iliac artery was saved by using a branched stent graft. The aneurysms were excluded with conventional endovascular aneurysm repair. Completion angiography showed technical success. Follow up computed tomography angiogram at three months showed complete exclusion of bilateral CIAAs, no endoleaks, and patent right internal iliac artery. There was no pelvic ischemic complication. We treated successfully a case of isolated bilateral CIAAs using an iliac branched stent graft.

BACKGROUND AND OBJECTIVES: Extracellular uridine 5'-triphosphate (UTP) regulates a variety of biological functions in the airway epithelium including chloride and fluid transport, mucociliary clearance, and mucin secretion via P2Y purinergic receptors. This study was undertaken to investigate which P2Y purinergic receptors are expressed in the normal human middle ear epithelial (NHMEE) cells. We also determined the levels of mucin secretion and its mRNA expressions following stimulation with UTP. MATERIALS AND METHOD: The level of P2Y (P2Y1, P2Y2, P2Y4, P2Y6, P2Y11 and P2Y12) receptors and mucin gene 5AC (MUC5AC), MUC5B, MUC8 messenger RNA (mRNA)s were measured by reverse transcription (RT)-polymerase chain reaction (PCR). We also determined the levels of mucin secretion following stimulation with UTP by dot-blotting method in NHMEE cells. RESULTS: Middle ear epithelial cells expressed P2Y1, P2Y2, P2Y6, P2Y11 and P2Y12 receptors but not the P2Y4 receptor. Apically applied UTP induced increased the mucin secretion. On the other hand, UTP did not enhance the mucin mRNA expression until 72 h had lapsed after treatment. CONCLUSION: Our study suggests that UTP acts as a secretogogue on mucin secretion in NHMEE cells.

Recently, Minimally invasive direct coronary artery bypass(MIDCAB) procedure eliminating cardiopulmonary bypass becomes one of the rapidly developing strategies in cardiac surgery. Here, we report a case of minimally invasive axillocoronary bypass as coronary reoperative procedure in which the previous LAD graft was occluded and the left internal mammary flow was deemed inadequate. The methodology is described with review of the relevant literature.

PURPOSE: To investigate associations between serum thyroid stimulating hormone (TSH) receptor antibody (TRAb) levels and Graves' orbitopathy (GO) activity/severity in chronic-stage GO and compare the performance of two newly-developed TRAb assays (third-generation TSH-binding inhibition immunoglobulin [TBII] assay versus Mc4 thyroid-stimulating immunoglobulin [TSI] bioassay). METHODS: This study is a retrospective review of medical charts and blood tests from Korean GO patients who first visited the departments of ophthalmology and endocrinology, Yonsei University College of Medicine from January 2008 to December 2011, were diagnosed with GO and Graves' hyperthyroidism, and were followed up for > or =18 months. Third-generation M22-TBII and Mc4-TSI assays were performed in the chronic-inactive GO patients in whom euthyroidism status was restored. Patients' GO activity/severity clinical activity scores (CAS), and modified NOSPECS scores were examined for a correlation with TRAb assays. RESULTS: Fifty patients (mean age, 41.3 years; 41 females) were analyzed. The mean duration of Graves' hyperthyroidism symptom was 63 months (range, 18 to 401 months) and that of GO was 46 months (range, 18 to 240 months). All patients had been treated previously with anti-thyroid drugs for a median period of 52.3 months, and two patients underwent either radioiodine therapy or total thyroidectomy. Mean CAS and NOSPECS scores were 0.5 +/- 0.9 (standard deviation) and 4.8 +/- 3.1, respectively. Mean M22-TBII and Mc4-TSI values were 7.5 +/- 10.2 IL/L and 325.9 +/- 210.1 specimen-to-reference control ratio. TSI was significantly correlated with NOSPECS score (R = 0.479, p < 0.001); however, TBII was not associated with NOSPECS score (p = 0.097). Neither TSI nor TBII correlated with CAS (p > 0.05), because GO inflammatory activity subsided in the chronic stages of GO. CONCLUSIONS: In chronic-inactive GO after euthyroid restoration, GO activity score did not associate with serum levels of TRAb or TBII. However, levels of the functional antibody Mc4-TSI did correlate with GO severity. Therefore, the TSI bioassay is a clinically relevant measure of disease severity even in chronic inactive GO.

OBJECTIVES: A stratified cross-over study was conducted to evaluate the effects of familiarity with computer on the performance of computerized neurobehavioral tests. Effects of keyboard type on the relationship between familiarity with computer and performance of computerized neurobehavioral tests were also examined. METHODS: We tested 70 persons classified into three groups according to degree of familiarity with computer: Group 1 was people with no computer competency, Group 2 had slight working experience on the computer, and Group 3 were highly competent and efficient on the computer. For each group, we executed 4 tests of the Korean version of the Swedish Performance Evaluation System (Simple Reaction Time, Addition, Symbol Digit, and Finger Tapping Speed). Three types of keyboard were applied for all three groups. Type 1 keyboard was a conventional layout with 106 keys. We removed the unused keys except for the 17 which were used in the test and remodeled the normal keyboard into Type 2 keyboard with 17 keys (10 numeric keys, 4 arrow keys, space bar, and both Ctrl keys). Type 3 keyboard with 11 keys consisted of 10 numeric keys and the space bar was newly developed for the computerized neurobehavioral performance test. RESULTS: It was found that Simple Reaction Time, Addition, and Finger Tapping Speed were not affected by familiarity with computer and type of keyboard. The mean reaction time of Symbol Digit adjusted by age and educational level with Type 1 keyboard was found to have significant difference among the three groups (F=3.347, p=0.041). The performance of Symbol Digit in Group 1 was found to be significantly lower than that in Group 2. The performances of Symbol Digit measured with Types 2 and 3 keyboards were not found to have significant differences among the three groups. In Groups 1 and 3, the performances of Symbol Digit measured with Type 1 keyboard were found to be significantly lower than those of other keyboards. CONCLUSIONS: According to the above results, Simple Reaction Time, Addition, and Finger Tapping Speed have high priority over other neurobehavioral tests for the workers having varying degrees of computer familiarity. It is also suggested that familiarity with computer and keyboard type needs to be considered in interpretation of the performance of Symbol Digit. We recommended executing the computerized neurobehavioral test with keyboards 2 or 3 to reduce the effect of computer familiarity.
