BACKGROUND: Both atrophic gastritis and intestinal metaplasia may progress to gastric dysplasia. This study aimed to analyze the factors influencing progression of atrophic gastritis and intestinal metaplasia to dysplasia. METHODS: People diagnosed with atrophic gastritis and intestinal metaplasia for the first time received a follow-up endoscopy and were investigated for the cumulative incidence rate of gastric dysplasia by age, gender, smoking habit, alcohol intake, rice consumption and family history of stomach cancer. RESULTS: The cumulative incidence rate increased with age, consuming > or =3 bowls of rice per day and family history of stomach cancer. Multivariate analysis showed that the cumulative incidence rate of gastric dysplasia increased in subjects >61 years (RR=2.54, P=0.014), in those consuming > or =3 bowls of rice per day (RR=1.46, P=0.021) and in those with a family history of stomach cancer (RR=1.31, P=0.037). CONCLUSIONS: More active management, such as intensive endoscopic follow-up examinations, lifestyle change and education regarding gastric dysplasia, are required in those older than 61 years, having a higher intake of grain or with a family history of stomach cancer.

OBJECTIVES: The purpose of this study was to compare psychological test profiles of psychiatric outpatients with high and low depression/suicide ideation and to identify predictor variables for depression/suicide ideation. METHODS: Component scores of the Personality Assessment Inventory (PAI) and Minnesota Multiphasic Personality Inventory-2 (MMPI-2) were compared using t-tests. Discriminant analysis was conducted for predictor variables of depression/suicide ideation. RESULTS: Regarding PAI profiles, somatic complaints (SOM), anxiety (ANX), anxiety-related disorder (ARD), depression (DEP), paranoia (PAR), borderline features (BOR), antisocial features (ANT), mania (MAN) drug problems (DRG) scores were significantly elevated in high depression and high suicide ideation groups. Concerning MMPI-2 profiles, the scores of hypochondriasis (Hs), depression (D), hysteria (Hy), psychopathic deviate (Pd), paranoia (Pa), psychasthenia (Pt), schizophrenia (Sc), social introversion (Si) were significantly elevated in these same groups. The PAI and MMPI-2 profile shapes were remarkably similar between high depression and high suicide ideation groups. Therefore, in terms of psychological profile, depression and suicidal ideation seemed to reflect the same construct. However, in discriminant analysis, significant predictors for depression were found to be Pt and D Sc from MMPI-2, while those for suicide ideation were found to be Pa and Sc, suggest subtle differences. CONCLUSION: The superficial characteristics of depression and suicide ideation groups reflected by the psychological test profiles seemed similar, but the determining factors may differ. Thus, the psychological interventions for these two groups may have to follow different routes considering these subtle differences.

STATEMENT OF PROBLEM: Changes of the marginal bone around dental implants have significance not only for the functional maintenance but also for the esthetic success of the implant. It was proposed that bone-retention elements such as microthreads at the coronal part of implant might help maintain the marginal bone level. PURPOSE: This study was designed to evaluate the effect of microthread configuration within the marginal coronal portion of the implant fixture at the marginal bone changes after loading around two different external hex implants. MATERIAL AND METHODS: Twenty-four patients were included and randomly assigned to treatment with Branemark system implants (Group 1, rough-surfaced implants, n=20) and Oneplant system implants (Group 2, rough-surfaced neck with microthreads, n=20). Clinical and radiographic examinations were conducted at baseline (implant loading) and 1 year postloading. Data analysis was performed by the SAS statistical package version 9.1.3 (SAS Institute, Cary, NC, USA) and the final model was calculated by the MIXED procedure (three-level ANCOVA) for marginal bone change of each test group at baseline and 1 year follow-up. RESULTS: Comparing to baseline, significant differences were noted in marginal bone level changes for the 2 groups at 1 year follow-up (P<0.05). Group 1 had a mean crestal bone level changes of 0.83+/-0.31mm; Group 2 had a mean crestal bone level changes of 0.44+/-0.36mm. Rough-surfaced with microthreads implants showed significantly less marginal bone loss than rough surfaced neck without microthread implants. CONCLUSION: A rough surface with microthreads at the implant was beneficial design to maintain the marginal bone level against functional loading.

Schwannomas are benign tumors derived from the Schwann cells of the nerve sheath. These are rare tumors that can be found in any part of the body although fewer than 4% of these tumors involve the nasal cavity and paranasal sinuses. Here, we present three cases of sinonasal schwannoma. The tumor masses were removed by endoscopic excision under general anesthesia. Pathological examination of the excised specimens confirmed schwannoma and the tumor cells were immunoreactive for S-100 protein. The patients are doing well with no evidence of recurrence.

PURPOSE: To evaluate the technical feasibility and clinical efficacy of the use of local thrombolysis for below-knee deep vein thrombosis (DVT). MATERIALS AND METHODS: From a population of 41 patients with a lower extremity DVT, the prospective clinical trial included 11 patients (7 female, 4 male, average age 61.4 years) treated with catheter-directed thrombolysis with urokinase for below-knee DVT. After removal of the proximal ilofemoral DVT, additional interventional procedures to remove the residual thrombus and restore the venous flow from the below-knee vein were performed in cases of continuous occlusion of venous flow from the popliteal and tibial veins. Under ultrasound (US) guidance, catheter-directed thrombolysis with urokinase was performed through the ipsilateral popliteal vein. After administration of oral anticoagulation therapy, CT and venography were performed to identify patency and the presence of a recurrent thrombosis. RESULTS: Successful removal of the thrombus and restoration of venous flow were achieved in all of the patients (100%). Restoration of flow with a residual thrombus occurred in one case. Focal venous stenosis was discovered in four cases. The duration of urokinase infusion was 1-4 days (average 2.36 days), which was considered long. For 15.2 months, the venous lumen of all cases was preserved without a recurrent thrombosis. CONCLUSION: Catheter-directed thrombolysis is an effective procedure for recanalization of below-knee DVT in patients with a lower extremity DVT.
