OBJECTIVE: This study compared the bone thickness of the palate between lateral cephalogram and 3D model measurements. METHODS: The subjects consisted of 30 adults (15 men,15 women) with a normal skeletal pattern and occlusion. The CT images were transformed to a 3D model, and were compared with the cephalometric image. Descriptive statistics for each variable were calculated. RESULTS: In the 3D CT model, the mid-palatal area was the thickest part. It became thinner as the palate tapered laterally. In the male group, the thinnest portion was positioned 6 mm away from the mid-palate, while in the female group the thinnest portion was 8mm away from the mid-palate. Correlation analysis between the lateral cephalometric and 3D CT model revealed a significant correlation except in the mid palatal area and the area 2 mm lateral to the mid-palate in men, whereas there was a significant relationship in every area in the women. In both men and women, the highest correlation appeared in the area 8 mm lateral to the mid palate. CONCLUSIONS: Using regression analysis, an actual prediction of the bone thickness between the measured bone thickness of the lateral cephalometric radiograph and 3D model was made. This will provide useful information for mini-implant length selection when inserting into the palate.

PURPOSE: Accurate evaluation of side branch (SB) ostium could be critical to the treatment of bifurcation lesions. We compared measured and calculated values of side branch ostial length (SBOL) in coronary bifurcation lesions with intravascular ultrasound (IVUS). MATERIALS AND METHODS: Pre-intervention and post-intervention IVUS was performed in 113 patients who underwent stent implantation of bifurcation lesions. For the IVUS longitudinal reconstruction of the bifurcation lesions, SBOL, SB diameter, and the angle between the distal portion of the main vessel (MV) and SB were directly measured. In addition, SBOL was calculated as: SB diameter/sin (angle between distal MV and SB). The relationship between measured and calculated SBOL was then evaluated. RESULTS: The angled between the distal MV and SB were 57.3+/-12.4degrees at pre-intervention and 59.4+/-12.6degrees at post-intervention. The mean measured and calculated SBOL values were 2.91+/-0.86 mm and 3.06+/-0.77 mm at pre-intervention and 2.79+/-0.82 mm and 2.92+/-0.69 mm at post-intervention, respectively. Differences between measured and calculated SBOL were 0.15+/-0.44 mm at pre-intervention and 0.13+/-0.41 mm at post-intervention. We found that calculated SBOL was correlated with measured SBOL (pre-intervention r=0.863, p<0.001; post-intervention r=0.868, p<0.001). CONCLUSION: There was a good correlation between measured and calculated SBOLs of the bifurcation lesions in IVUS longitudinal reconstruction. SBOL in the bifurcation lesions can therefore be estimated using the SB diameter and the angle between distal MV and SB.

BACKGROUND AND OBJECTIVES: With recent advances in equipment and techniques, infrapopliteal angioplasty has shown results that are comparable to those of surgical bypass in patients with critical limb ischemia (CLI). In this study, we evaluated the efficacy and the feasibility of infrapopliteal angioplasty in patients with CLI. SUBJECTS AND METHODS: Between March 2002 and May 2008, infrapopliteal angioplasty was performed on 118 limbs of 101 patients (79 males; mean age 66 years) with CLI (Rutherford category 4, 5 or 6). Freedom from reintervention, limb salvage, and overall survival were analyzed. RESULTS: The median follow-up duration was 30 months. Initial technical and clinical success rates were 69.5% and 83.1%, respectively. No major complication requiring surgical intervention developed after angioplasty. Among 82 limbs with initial technical success, the rate of freedom from any reintervention at 2 years was 70.7% and that from limb salvage was 97.6%. Young age and Rutherford category 6 at initial presentation were independent predictors associated with poor 2 year primary patency in these patients with CLI. Overall survival at 1 year was 86.4% and that at 2 years 76.3%. A history of cerebrovascular accident was an independent predictor associated with poor 2 year survival in these patients. CONCLUSION: Infrapopliteal angioplasty as a primary choice of treatment in CLI patients showed favorable clinical outcomes and feasibility.

A 65-year old Korean man, living in Mokpo-city, Jeollanam-do, Republic of Korea, visited a local clinic complaining of right upper quadrant pain and indigestion. At colonoscopy, he was diagnosed as having a carcinoma of the ascending colon, and thus, a palliative right hemicolectomy was performed. Subsequently, an adult fluke of Gymnophalloides seoi was incidentally found in a surgical pathology specimen of the lymph node around the colon. The worm was found to have invaded gut lymphoid tissue, with characteristic morphologies of a large oral sucker, a small ventral sucker, and a ventral pit surrounded by strong muscle fibers. This is the first reported case of mucosal tissue invasion by G. seoi in the human intestinal tract.

OBJECTIVES: The authors attempted to evaluate the diagnostic validity of the Korean version, Geri-atric Depression Scale(GDS) for screening geriatric DSM-III-R major depression among clinical pop-ulations. METHODS: Through of preliminary trials 3 times, the authors translated GDS including Short form Geriatric Depression Scale(SGDS) into Korean. GDS, SGDS, HRS-D, CES-D was adminis-tered to 88 elderly psychiatric patients(35 major depressives, 51 were non-major depression) and also Diagnostic Interview Schedule(DIS-III-R) was administered independently to diagnoses DSM-III-R major depression. Reliability and validity test 5, optimal cut-off point estimation, and ROC curve analysis were done to investigate the diagnostic validity of GDS and SGDS. RESULTS: Internal consistency-reliability and concurrent validity of GDS, SGDS associated with other depression scales(HRS-D, CES-D) were excellent. Content validity and discriminant validity which differentiate DSM-III-R major depression from non-major depression was also good. The authors suggest the score '17' as the optimal cut-off point of GDS for screening DSM-III-R major depression among clinical populations and the score '8' as optimal cut-off score of SGDS. ROC curve analysis revealed wide AUC of both GDS and SGDS, which indicates its high diagnostic validity in assessing DSM-III-R major depression. The GDS and SGDS were found to be highly correlated(r=0.9594) and any difference of AUC between both scales in ROC curve analysis were not found. This finding suggests that SGDS can be an adequate substitute for GDS. CONCLUSION: The GDS and SGDS are valid and reliable case finding tools for screening DSM-III-R major depression among clinical populations in Korea but relatively high cut-off point demands the further evaluation in the viewpoint of culturally determined style of response for the depression questionnaire in Korea.

PURPOSE: The aim of this study was to determine whether retinol-binding protein 4 (RBP4), adiponectin and high molecular weight (HMW) adiponectin are associated with insulin resistance (IR) and metabolic parameters in non-diabetic hypertensive patients. Also, we sought to compare the predictive values of these adipocytokines for IR in non-diabetic hypertensive patients. MATERIALS AND METHODS: Analyses of RBP4, adiponectin, and HMW adiponectin were performed on 308 non-diabetic hypertensives (148 males, age 58 +/- 10 years, 189 non-metabolic syndrome and 119 metabolic syndrome). The homeostasis model assessment (HOMA) index for IR, lipid profiles, and anthropometric measure-ments were assessed. RESULTS: There was no significant difference in RBP4 levels according to the presence of metabolic syndrome, although adiponectin and HMW adiponectin were significantly lower in metabolic syndrome. Correlation analysis of log RBP4 with IR and metabolic indices revealed that there was no significant correlation of RBP4 with waist circumference (r = 0.056, p = 0.324), HDL cholesterol (r = 0.005, p = 0.934), ApoB/ApoAI ratio (r = 0.066, p = 0.270), and the HOMA index (r = 0.017, p = 0.756). However, adiponectin and HMW adiponectin showed significant correlations with the HOMA index (r = - 0.247, p < 0.001; r = - 0.296, p < 0.001) and metabolic parameters. With IR defined as HOMA index > or = 2.5, HMW adiponectin did not demonstrate a superior predictive value for IR compared to adiponectin (AUC = 0.680 vs. 0.648, p = 0.083). The predictive value of RBP4 for IR was minimal (AUC = 0.534). CONCLUSION: RBP4 was not associated with IR or metabolic indices and the predictive value for IR was minimal in hypertensives. HMW adiponectin didn't have a superior predictive value for IR compared to adiponectin. Therefore, we can suggest that RBP4 and HMW adiponectin don't have more additive information than adiponectin in non-diabetic hypertensives.

Henoch-Schonlein purpura (HSP) is a vasculitis of the small vessels in skin, joints, gastrointestinal (GI) tract and kidney. GI symptoms occur in up to 85% of patients and may lead to severe problems such as intussusception, obstruction, and perforation. GI symptoms may not be easily controlled, showing refractoriness to the conventional corticosteroid therapy. Although GI involvements of HSP are acute, and self-limited in most instances, they may cause fatal results in some unusual cases. In such conditions all the possible therapeutic modalities should be considered. We report two cases of severe small bowel involvement of HSP. One case presented with severe abdominal pain showing refractoriness to corticosteroid, but improved with IV immunoglobulin therapy. In the second case, HSP with transmural infarction in the small bowel could be cured with surgical intervention.

Contrast-induced nephropathy (CIN) is a serious complication in patients undergoing percutaneous coronary intervention (PCI), and is associated with higher morbidity and mortality. The limiting volume of contrast medium is safest and most reliable strategy for CIN prevention. Intravascular ultrasound (IVUS) serves as an attractive alternative imaging tool to angiography in many steps during PCI, thereby reducing the use of contrast agents. Here, we reported a case of successfully treated unprotected left main bifurcation lesion with heavily calcified and diffuse lesion under the IVUS-guided PCI using low volumes of contrast dye of total 12 cc in an elderly patient.
