Backgound: The placement of stents in coronary arteries has been shown to reduce acute closure and restenosis in comparison to balloon angioplasty. However, clinical use of intracoronary stents is impeded by the subacute stent thrombosis and hemorrhagic complications associated with the anticoagulant regimen. It's known that the complete stent deployment with high pressure inflation and new antiplatelet agents are effective in reduction of subacute thrombosis and hemorrhage. So we evaluated initial results (success and complication rate) after high pressure-stent deployment with new anticoagulation protocol. METHODS: One hundred and ninety one patients with 201 lesions were treated with 231 stents of various types. The high pressure balloon inflation and antiplatelets agents were used in all cases. Final high pressure balloon inflation guided by IVUS were performed in 23 consecutive cases with incomplete stent deployment according to angiographic findings. RESULTS: 1) The indications of stenting (n=210) were De novo in 124 (59%), bailout procedure in 57 (27%), suboptimal result after PTCA in 19 (8%), and restenosis after PTCA in 14 (6%). The location of lesions were LAD in 101, RCA in 67, circumflex in 28, ramus intermedius in 3, and LMT artery in 2 lesions. Angiographic morphologic characteristics were type A in 2, type B in 158 (B1: 57, B2: 101), and type C in 22 lesions. 2) The angiographic and clinical success rate was 96% (192/201) and 92% (186/201) respectively. 3) In angiographic analysis, the baseline average reference vessel dirmeter was 3.33+/-0.35 mm. Baseline minimum lumen diameter (MLD) was 0.58+/-0.29 mm, with baseline percent diameter stenosis of 82.86+/-8.64%. The final stent diameter was 3.37+/-0.29 mm, with mean final percent stenosis of 0.63+/-8.25. The mean MLD after stenting was significantly increased (p<0.001). The mean MLD within stent increased 14%, from 2.91+/-0.39 mm at the nominal balloon inflation (inflation pressure=7 atm) to 3.37+/-0.29 mm at high pressure balloon inflation (inflation pressure <0A65B>12atm) (p<0.001). The length of lesions in GR I (cook), GR II, and Micro II stents were significantly longer than ones in PS, Cordis, Wiktor, Nir (p<0.001). 4) In intravascular ultrasound analysis, the mean lumen CSA at the tightest point within stent increased 11%, from 8.4+/-2.4 mm2 at the intial intravascular ultrasound to 9.4+/-2.1 mm2 at the final intravascular ultrasound (p<0.001). 5) The procedural and postprocedural complications were 2 acute closures associated with AMI and emergent CABG, 1 subacute closure which was revascularized by bail out stenting, 5 major hemorrhage requiring transfusion associated with 1 CVA and 2 metabolic acidosis induced by acute renal failure, and 5 death. CONCLUSION: The high pressure stent deployment procedure and new anticoagulation protocol associating tidopidine and aspirin without coumadin or prolonged heparin infusion allow us to obtain an acceptably low subacute thrombosis or bleeding complication rate. These results are encouraging and allow a wide use of coronary stenting.

BACKGROUND: Dopamine is an inotropic agent that is often selected for continuous infusion. For hemodynamic stability, the rate of infusion is controlled in the range of 5-15 µg/kg/min. This study aimed to compare the time intervals from the administration of dopamine to the onset of its hemodynamic effects when dopamine was administered through three different peripheral veins (the cephalic vein [CV], the great saphenous vein [GSV], and the external jugular vein [EJV]). METHODS: Patients in group 1, group 2, and group 3 received dopamine infusions in the CV, GSV, and EJV, respectively. A noninvasive continuous cardiac output monitor (NICCOMO™, Medis, Ilmenau, Germany) was used to assess cardiac output (CO) and systemic vascular resistance (SVR). Six minutes after intubation, baseline heart rate (HR), systolic blood pressure (BP), diastolic BP, mean arterial pressure (MAP), CO, and SVR values were recorded and dopamine infusion was initiated at a dose of 10 µg/kg/min. Hemodynamic changes at 0, 4, 8, 12, and 15 minutes postinfusion were recorded. RESULTS: No statistically significant differences were observed among the three groups with respect to the rate of hemodynamic change. In all groups, systolic BP, diastolic BP, MAP, and SVR tended to increase after decreasing for the first 4 minutes; in contrast, HR and CO decreased until 8 minutes, after which they tended to reach a plateau. CONCLUSIONS: For patients under general anesthesia receiving dopamine at 10 µg/kg/min, there were no clinical differences in the effect of dopamine administered through three different peripheral veins.

PURPOSE: To determine the learning curve of dacryocystorhinostomy (DCR) performed by a single oculoplastic surgeon after one year of fellowship training. METHODS: This retrospective review study comprised nasolacrimal duct obstruction patients that underwent endonasal DCR at our hospital between February 2006 and February 2008. The patients that completed at least six months of follow-up were included in the analysis. Exclusion criteria were patients less than 20 years of age and NLD obstructions due to malignancy or canalicular obstructions. Success was defined as duct patency on syringing at the final follow-up and no complaints of epiphora. RESULTS: Out of 161 eyes, the overall surgical success rate was 83.2% (134/161 eyes) and the mean postoperative follow-up period was 6.5 months (6-18 months). Success rates gradually increased as follows: 71.2% (37/52 eyes) for the first group, 88.7% (47/53 eyes) for the second group, and 89.3% (50/56 eyes) for the third group (second and third group compared to first group, p = 0.025, p = 0.017, respectively). CONCLUSIONS: To ensure high DCR success rates, the novice surgeon should perform at least 50 surgeries.

PURPOSE: To investigate the effects of commodified growth factor products used clinically on fibrovascular ingrowth into porous polyethylene orbital implants. METHODS: Porous polyethylene orbital implant sheets (Medpor(R)) soaked with Nepidermin (Easyef(R)), Trafermin (Fiblast(R)), and normal saline were implanted into the backs of 18 Sprague-Dawley rats. The degree of fibrovascular ingrowth as observed using a light microscope was compared 1 and 2 weeks after implantation and was calculated as a percentage of the fibrovascular ingrowth length. RESULTS: One week after implantation, the percentage of fibrovascular ingrowth length was 25.33 +/- 5.43%, 22.56 +/- 5.30%, and 21.78 +/- 4.66% in the Easyef(R)-, Fiblast(R)- and normal saline-soaked groups. The degree of fibrovascularization was higher in the Easyef(R)-soaked group than in the other groups (p = 0.020, 0.012). Two weeks after implantation, the degree of fibrovascularization was 98.33 +/- 5.00%, 100.00 +/- 0.00%, and 95.89 +/- 4.57%, which was significantly higher in the Easyef(R)-, and Fiblast(R)-soaked groups than in normal saline-soaked group (p = 0.019, <0.001). CONCLUSIONS: Commodified growth factor products used in other areas selectively enhanced fibrovascular ingrowth to a greater degree and earlier in ophthalmic plastic and reconstructive surgery.

An increase in the dose of chemotherapy enhances the response of many experimental and clinical cancers, but the extent of chemotherapy dose escalation and repeated use is often limited by myelosuppression. The side effects of chemotherapy including bleeding and infection due to myelosuppression have resulted in delayed therapy and a reduction in the therapeutic dose, therefore it is necessary to overcome myelosuppression especially leukopenia in patients with gynecologic malignancies who recieved chemotherapy. This study is undertaken to investigate the clinical effects of rhG-CSF(recombinant human Granulocyte-colony stimulating factor) in 29 patients with gynecologic malignancy who recieved chemotherapy. It was given at a dose of 100 microgram bid/day subcutaneously until significantly increase of leukocyte count in leukopenic patient. The results showed, the rhG-CSF has significantly increased the number and function of leukocyte. The use of rhG-CSF was effective and useful to treat chemotherapy induced leukopenia and to accelerate the recovery from this complications.

Xeroderma pigmentosum is rare autosomal recessive disease, characterized by extreme sensitivity to ultraviolet light and leading to development of multiple malignant skin tumors. Among multiple malignant skin tumors, basal cell carcinoma and squamous cell carcinoma are common. Treatments of xeroderma pigmentosum are palliative or radiation treatment, but surgical resection is necessary if xeroderma pigmentosum is transited to malignant skin tumors. We report a case of a 32-years-old female xeroderma pigmentosum patient, who developed radiation resistant basal cell carcinoma on right alar nasi. Radiaton theraphy(300cGy, fractions: 10, total dose: 3000cGy) was not effective, so surgical excision and local skin flap coverage was made and no specific wound complications occurred. During 11 months follow-up period, no evidence of recurrence was found.

PURPOSE: This study identifies the optimal incision site by describing the relationship between McBurney's point and the base of appendix using the coronal view of abdominal multi-detector computed tomography (MDCT) in patients with acute appendicitis. METHODS: We reviewed the records of 206 patients with positive MDCT findings who were histologically diagnosed with acute appendicitis after appendectomy between January 2014 and September 2015. The outer 1/3 point between two points, the umbilicus and the right anterior superior iliac spine, was marked as McBurney's point on the coronal view. The superoinferior, mediolateral and radial distances between the base of appendix and McBurney's point were measured and recorded. RESULTS: The average age was 35.1±20.3 years. There were 34 patients below the age of 15-years-old (children), and 172 patients over 15-years-old (adults). In 35.4% of patients, the base of appendix was located within a radius of 2 cm from the McBurney's point, in 39.8% it was within 2~4 cm, and in 24.8% was over 4 cm. The average center coordinate of the base of inflamed appendix in our patients is 9.32 mm, 8.31 mm and the distance between two points is 12.5 mm. CONCLUSION: The location of appendix has wide individual variability; therefore the McBurney's point has limitations as an anatomic landmark. If we choose to customize appendectomy incisions considering the base of appendix by using an abdominal MDCT coronal view, additional incision site extension can be reduced.

The omphalomesenteric duct is a link between the primitive midgut and the yolk sac. Normally, the duct obliterates around 6 weeks of gestation, yet varying degrees of incomplete obliteration can take place in 1%–4% of infants. This study described the case of a newborn with a patent omphalomesenteric duct remnant fistula identified at birth with meconium in the umbilical cord. At birth, the infant presented meconium staining and meconium discharged within the umbilical cord. Physical examination and other examinations showed no other specific findings. The omphalomesenteric duct fistula was confirmed through the imaging study (abdominal ultrasonography, gastrografin enema). A surgery was carried out where the remnant was resected. The patient did well and was discharged soon after without complication.
