BACKGROUND AND OBJECTIVES: This trial evaluated the safety and efficacy of the Genoss drug-eluting coronary stent. METHODS: This study was a prospective, multicenter, randomized trial with a 1:1 ratio of Genoss drug-eluting stent (DES)™ and Promus Element™. Inclusion criteria were the presence of stable angina, unstable angina, or silent ischemia. Angiographic inclusion criteria were de novo coronary stenotic lesion with diameter stenosis >50%, reference vessel diameter of 2.5–4.0 mm, and lesion length ≤40 mm. The primary endpoint was in-stent late lumen loss at 9-month quantitative coronary angiography follow-up. Secondary endpoints were in-segment late lumen loss, binary restenosis rate, death, myocardial infarction (MI), target lesion revascularization (TLR), target vessel revascularization (TVR), and stent thrombosis during 9 months of follow-up. RESULTS: We enrolled 38 patients for the Genoss DES™ group and 39 patients for the Promus Element™ group. In-stent late lumen loss at 9 months was not significantly different between the 2 groups (0.11±0.25 vs. 0.16±0.43 mm, p=0.567). There was no MI or stent thrombosis in either group. The rates of death (2.6% vs. 0%, p=0.494), TLR (2.6% vs. 2.6%, p=1.000), and TVR (7.9% vs. 2.6%, p=0.358) at 9 months were not significantly different. CONCLUSION: This first-in-patient study of the Genoss DES™ stent showed excellent angiographic outcomes for in-stent late lumen loss and major adverse cardiac events over a 9-month follow-up.

This study compared two-stent strategies for treatment of bifurcation lesions by stenting order, 'main across side first (A-family)' vs 'side branch first (S-family). The study population was patients from 16 centers in Korea who underwent drug eluting stent implantation with two-stent strategy (A-family:109, S-family:140 patients). The endpoints were cardiac death, myocardial infarction (MI), stent thrombosis (ST), and target lesion revascularization (TLR) during 3 years. During 440.8 person-years (median 20.2 months), there was 1 cardiac death, 4 MIs (including 2 STs), and 12 TLRs. Cumulative incidence of cardiac death, MI and ST was lower in A-family (0% in A-family vs 4.9% in S-family, P = 0.045). However, TLR rates were not different between the two groups (7.1% vs 6.2%, P = 0.682). Final kissing inflation (FKI) was a predictor of the hard-endpoint (hazard ratio 0.061; 95% CI 0.007-0.547, P = 0.013), but was not a predictor of TLR. The incidence of hard-endpoint of S-family with FKI was comparable to A-family, whereas S-family without FKI showed the poorest prognosis (1.1% vs 15.9%, retrospectively; P = 0.011). In conclusion, 'A-family' seems preferable to 'S-family' if both approaches are feasible. When two-stent strategy is used, every effort should be made to perform FKI, especially in 'S-family'.

Isolated pancreatic trauma and secondary obstructive jaundice in the pediatric population is unusual. Biliary tract obstruction can be a major cause of acute pancreatitis. We report a case of obstructive jaundice secondary to isolated traumatic acute pancreatitis in a previously healthy 32-month-old girl. In our case, secondary obstructive jaundice aggravated the pancreatic inflammation and was successfully treated with percutaneous transhepatic biliary drainage (PTBD).

BACKGROUND AND OBJECTIVES: The thrombolysis in myocardial infarction (TIMI) myocardial perfusion grade (TMPG) is associated with the long term clinical outcomes. This study compared the TMPG with the myocardial viability as determined by 18F-fluorodeoxyglucose positron emission tomography (FDG-PET), and with improvement of the left ventricular (LV) function on echocardiography. SUBJECTS AND METHODS: We enrolled 44 consecutive patients (37 men: age 56+/-11 years) who underwent primary percutaneous coronary intervention (PCI) for ST segment elevation myocardial infarction (STEMI). We assessed the coronary flow reserve (CFR), the diastolic deceleration time (DDT), the coronary wedge pressure (Pcw) and the coronary wedge pressure/mean aortic pressure (Pcw/Pa). All the patients underwent FDG-PET scans on the 7th day after primary PCI. The patients were divided into 3 groups according to the TMPG (TMPG 0/1: n=18, TMPG 2: n=14, TMPG 3: n=12). RESULTS: There was a significant correlation between the TMPG and the CFR, DDT, Pcw and Pcw/Pa (r=0.367, p=0.017; r=0.587, p<0.001; r=-0.513, p<0.001; r=-0.614, p<0.001, respectively). There was a significant correlation between the TMPG and the % of FDG uptake (r=0.587, p<0.001) and the patients with TMPG 3 had the most favorable % of FDG uptake (TMPG 0/1 vs TMPG 2 vs TMPG 3; 42.0+/-12.3% vs 53.9+/-11.2% vs 59.3+/-13.3%, p=0.001). On echocardiography, the patients with TMPG 3 revealed an improvement of the LV ejection fraction (53.4+/-9.9% vs 60.0+/-7.0%, p=0.004) and the patients with TMPG 2 and TMPG 3 revealed improvement of their regional wall motion abnormality (RWMA) index (1.44+/-0.26 vs 1.24+/-0.18, p=0.022; 1.35+/-0.26 vs 1.15+/-0.18, p=0.018, respectively). CONCLUSION: The angiographically determined TMPG might be clinically useful for the assessment of myocardial viability and it might be a useful predictor for improvement of the LV function in patients suffering with STEMI.

PURPOSE: Extra-thyroidal extension has been recognized as a poor prognostic factor for increased regional recurrence risk in papillary thyroid carcinoma, and is known to require treatment that is more aggressive. In the recent UICC TNM 6th Classification, an extra-thyroidal extension was divided into a minimal extra-thyroidal extension (T3) and a massive extra-thyroidal extension (T4). The aim of this study was to investigate the clinical effect of a minimal extra-thyroidal extension of a papillary carcinoma for the recurrence of regional cervical lymph nodes. METHODS: We retrospectively studied 154 patients with papillary thyroid carcinoma where a thyroidectomy was performed from Feb. 2003 to May. 2006 at the Department of Surgery, with the exclusion of 6 patients with a massive extra-thyroidal extension. We divided the cases into a no extra-thyroidal extension group and a minimal extra-thyroidal extension group according to the grading of the extra-thyroidal extension. The grading of the extra-thyroidal extension was based on both pathological findings and intraoperative surgical findings. Clinicopathological factors associated with each group were analyzed by univariate and multivariate analysis. We divided the cases into two groups according to age (<45 yrs, > or =45 yrs) and lymph node status (positive, negative), and compared each group with regards to disease free survival according to the grading of the extra-thyroidal extension. RESULTS: By univariate analysis, a minimal extra-thyroidal extension was related to lymph node metastasis, tumor size, mutifocality (P<0.05), and was not related to cervical lymph node recurrence statistically (P=0.108). Cervical lymph node recurrence was related to being male, lymph node metastasis and tumor size (P<0.05). By multivariate analysis, a minimal extra-thyroidal extension was independently related to tumor size, multifocality, and lymph node metastasis (P<0.05). In both groups with regards to age and lymph node status, a minimal extra-thyroidal extension was not statistically related to disease free survival (P>0.05). CONCLUSION: We need to downstage to less than T3 for a minimal extra-thyroidal extension because there is no significant difference in disease free survival according to the grading of an extra-thyroidal extension in patients with papillary thyroid carcinoma.

BACKGROUND AND OBJECTIVES: The state of the coronary microcirculation is an important determinant of the myocardial viability and clinical outcomes for patients suffering with acute myocardial infarction (AMI). However, there are scant comparative studies on the most reliable invasive, on-site measurement for assessing the microvascular integrity and myocardial viability in AMI patients. The aim of this study is to evaluate the usefulness of a novel index of microcirculatory resistance (IMR) and the coronary physiologic parameters for predicting the myocardial viability after primary percutaneous coronary intervention (PCI) in AMI patients. SUBJECTS AND METHODS: Twenty-four patients (21 males, mean age: 55+/-11 years) underwent primary PCI for AMI (LAD: 17, RCA: 6, LCX: 1) were enrolled. After successful PCI, using a pressure-temperature sensor-tipped coronary wire, the thermodilution-derived CFR (CFRthermo) and coronary wedge pressure (Pcw) were measured and the ratio of the Pcw and the mean aortic pressure (Pcw/Pa) was calculated, along with the IMR, which was defined as the distal coronary pressure divided by the inverse of the hyperemic mean transit time. 18F-fluorodeoxyglucose (FDG) PET was performed after primary PCI at 7 days post-AMI to evaluate the myocardial viability by the regional percentage of FDG uptake in the infarct-related segments. RESULTS: There were good correlations between all the coronary pressure measurements and the regional FDG uptake (CFRthermo, r=0.454, p=0.026; Pcw, r=-0.407, p=0.048; Pcw/Pa, r=-0.480, p=0.018; IMR, r=-0.696, p<0.001, respectively). Multiple logistic regression analysis demonstrated that the IMR was an adjusted predictor for myocardial viability as defined by the 50% FDG-PET threshold value among all the coronary pressure measurements (OR=0.884, p=0.021). The cut-off value of IMR for predicting myocardial viability was 22 U (a sensitivity of 82%, a specificity of 85% and an accuracy of 85%). CONCLUSIONS: Intracoronary pressure wire-based indexes are useful for on-site assessment of myocardial viability after primary PCI. IMR is a novel index that represents the microvascular integrity, and it is a better predictor of myocardial damage than the current techniques for evaluating the microvasculature after primary PCI.

Autoimmune hemolytic anemia (AIHA) is characterized by the production of antibodies directed against red blood cells (RBCs). It is usually accompanied by normal white blood cell (WBC) and platelet counts. Severe leukocytosis and thrombocytosis in AIHA are rare. Here, we report a 3-year-old female child who showed AIHA by warm antibody testing with both leukocytosis and thrombocytosis. The patient was treated with oral steroids for 5 days. During treatment, the leukocytosis was noted on hospital day 3 and was up to 60.87 x 10(9)/L. In addition, the thrombocytosis persisted at up to 725 x 10(9)/L. After day 7, the WBC and platelet counts returned to the normal range. The clinical condition and vital signs improved. The patient was discharged on day 12. This case demonstrated that patients with primary AIHA, may also have leukocytosis and thrombocytosis.

Albright's hereditary osteodystrophy is an inherited syndrome that encompasses endocrinologic anomaly of pseudohypoparathyroidim or less commonly, pseudo-pseudohypoparathyroidism and various physical stigmata such as mental retardation, short stature, skeletal anomaly of the hands, abnormal dentition, round facies, and osteoma cutis. Primary osteoma cutis in this syndrome presents at birth or in early infancy, preceding most of the other manifestations. This case is a typical presentation with osteoma cutis as the sole initial manifestation. Rather unfamiliar to dermatologists, Albright's hereditary osteodystrophy still deserves to be included in the differentials when an isolated case of osteoma cutis presents in a young child.

PURPOSE : 99mTc DMSA renal scan have been widely used not only for the evaluation of renal scars but also for the diagnosis of acute pyelonephritis. Recent studies have shown SPECT images have higher accuracy than the planar images with some controversy. We evaluated the availability of the SPECT images adding to planar images for the diagnosis of acute pyelonephritis(APN) and renal scar in children with urinary tract infection (UTI). METHODS : 130 children with UTI (260 kidney units) and 22 follow-up children (44 kidney units) were included between January 1, 1997 and July 31, 1999 at Ewha University Mokdong Hospital. Planar Anterior and posterior images and SPECT axial and coronal images of 99mTc DMSA renal scan were obtained with Starcam 4000-i U.S.A. GE at 3 hours after 99mTc DMSA I.V. injection. The data were analyzed by Chi square test after Yates's correction. RESULTS : The detection rate of the acute pyelonephritis by SPECT images was 12.3% higher than that of planar images (47.7% vs 35.4%) by the patient and 6.9% higher also (31.9% vs 25.4%) by the kidney unit. 18 kidney units with negative planar images had focal defect in 10 kidney units (3.8%) and multifocal defect in 8 kidney units (3.1%) on SPECT images, but 1 kidney unit with positive planar image had negative SPECT image. SPECT images were superior to the planar images in 17.3%, identical in 82.3% and inferior in 0.4% to planar image. The detection rate of the renal scars by SPECT images was 13.7% higher than planar images by the patient (68.2% vs 54.5%) and 6.8% higher also (43.2% vs 36.4%) by the kidney unit. SPECT images were superior to the planar images in 17.3% and identical in 82.3% to planar image. CONCLUSION : SPECT images had shown higher detection rate and better image than planar images for the diagnosis of the acute pyelonephritis and the evaluation of the renal scars.
