PURPOSE: To review the clinical and laboratory features of patients with Wilson disease at diagnosis. METHODS: In this retrospective study, records of all 20 patients, who were diagnosed as having Wilson disease at the Paik hospital in Busan from 1990 to 2000, were reviewed. RESULTS: Out of 20 patients, 12 pateints (60%) have hepatic presentation alone, 2 patients (10%) have neurologic presentation, 4 patients (20%) have hepatic and neuropsychiatric presentation, and one patient (5%) has hematologic presentation at diagnosis. One patient (5%) has neither symptom nor laboratory finding of Wilson disease except very low serum ceruloplasmin level and positive family history. Family screening test revealed 3 cases of Wilson disease. 12 patients were revealed to be combined with liver cirrhosis at diagnosis. CONCLUSION: Early diagnosis and treatment is very important in patients with Wilson disease. Children or adolescents who manifest symptoms of hepatitis, who has prolonged elevation of liver enzymes, and has family history of hapatitis of unknown origin, with mild hematologic or urinary abnormalities must be suspected to have Wilson disease. Also, in adolescents with extrapyramidal symptoms or other neuropsychiatric symptoms, liver function test should be done.

PURPOSE: Bipolar energy has recently been used for transurethral resection of bladder tumor (TURBT). Although this modality is thought to be safe, there are some controversies concerning the pathologic accuracy of the biopsy specimens. We compared clinical efficacy, safety, and pathologic characteristics of deep biopsy specimens between bipolar and monopolar devices. MATERIALS AND METHODS: From January 2002 to June 2007, a total of 115 patients underwent TURBT with deep biopsy with the use of bipolar (bipolar group, n=64) or monopolar (monopolar group, n=51) devices. We retrospectively analyzed tumor size, tumor number, urine cytology, perioperative blood loss (postoperative changes in hemoglobin levels), complications, duration of catheterization, duration of hospitalization, pathologic stage, WHO grade, deep biopsy specimen thickness, and grade of thermal damage. RESULTS: There were no statistical differences in tumor size, tumor number, urine cytology, complications, duration of hospitalization, pathologic stage, or WHO grade between the two groups. Postoperative changes in hemoglobin levels were significantly lower in the bipolar group (p=0.038), and the duration of catheterization was shorter in the bipolar group (p=0.026). The deep biopsy specimen thickness was significantly thinner in the bipolar group (2.25+/-0.94 mm vs. 3.02+/-1.39 mm, p<0.05). The grade of thermal damage was not statistically different between the two groups (p=0.862). CONCLUSIONS: In terms of clinical efficacy and safety, bipolar TURBT is comparable to monopolar TURBT, having advantages in perioperative blood loss and duration of catheterization. In addition, pathologic changes in deep biopsy after bipolar and monopolar TURBT are similar. Bipolar TURBT can be properly used for bladder tumors without pathologic error.

Global aphasia without other focal neurologic lateralizing signs (GWLS) is an uncommon stroke syndrome. The pathogenesis of GWLS has been thought as the result of multiple cardioembolism. However, a few cases of GWLS with a single lesion have been reported. We report an unusual case of GWLS with a single left superior temporal infarction. A 73-year-old right handed man was admitted with receptive and expressive language impairment without other focal neurologic lateralizing signs. The patient's global aphasia symptom has being 4 weeks after symptom onset. Brain CT showed only one lesion of left superior temporal lobe. Our case notes that the multiple lesions of the speech area are not only necessary to produce GWLS, and it is not necessarily imply a double lesion or an embolic causes.

PURPOSE: Low urinary pH is a risk factor for uric acid stones, and acidic urine has been described as a renal manifestation of the metabolic syndrome. We evaluated the association between metabolic syndrome and urinary pH in adult Korean men who visited a health promotion center. MATERIALS AND METHODS: From 2004 to 2008, a total of 18,513 adult men who visited our health promotion center were enrolled in this study. The relation between urinary pH and various parameters associated with the metabolic syndrome were evaluated. RESULTS: The average age was 45.6 years (range, 18-95 years), and 4987 men (26.9%) were classified as having the metabolic syndrome. The mean urinary pH of the metabolic syndrome group was 5.91, which was significantly lower than that of the normal group (6.08). In univariate and multivariate analysis, body mass index, serum triglyceride, and blood sugar were negatively correlated with urinary pH (p<0.05). In multivariate logistic regression analysis, obesity (body mass index > or =25 kg/m2), hypertriglyceridemia (> or =150 mg/dl), high fasting glucose (> or =110 mg/dl), and low high-density lipoprotein cholesterol (<45 mg/dl) were the significant factors that predicted low urinary pH (< or =5.5). CONCLUSIONS: Metabolic syndrome was related to lower urinary pH in ostensively healthy adult Korean men. Further studies are needed to elucidate the exact mechanism responsible for the lower urinary pH in individuals with the metabolic syndrome.

BACKGROUND AND PURPOSE: Although the 15-item Geriatric Depression Scale (GDS15) is a widely used depression screening questionnaire, the implications of the GDS15 in patients with Alzheimer's disease (AD) are questionable. We designed this study to explore the GDS15 factor structure and the relationships between these factors and cognitive-behavioral aspects. METHODS: The GDS15, cognitive function tests, and the Korean-Neuropsychiatry Inventory were administered to 310 patients with probable AD, who were not medicated before visiting the hospital. Three factors were identified by principal components analysis. A bivariate correlation analysis was conducted to determine the relationships between factors and neurocognitive and behavior symptoms. RESULTS: Factor 2 was correlated with the Korean Boston Naming Test, calculating ability, the go-no-go test, the Controlled Oral Word Association Test (COWAT), the Color Word Stroop Test (CWST; words and color), aggression, depression, and apathy. Factor 3 was correlated with calculating ability, the Seoul Verbal Learning Test, immediate recall, copy, and delayed recall on the Rey-Osterieth Complex Figure Test, contrasting on the COWAT, and words and delusion on the CWST. We identified three factors and revealed that the GDS15 may be comprised of a heterogeneous scale. CONCLUSIONS: These results suggest that the GDS15 may be comprised of a heterogeneous scale and suggest multi-dimensional properties of the GDS15 in patients with AD.

PURPOSE: The purpose of this study was to compare the marginal fit of three-unit zirconia fixed dental prostheses (FDPs) fabricated using CAD/CAM and MAD/MAM system. MATERIALS AND METHODS: Dentiform maxillary central and lateral incisor were prepared for 3-unit FDP and fixed in yellow stone. This model was duplicated to epoxy resin die. On the resin die, fifteen 3-unit FDPs were fabricated. Metal-ceramic group was three-unit metal-ceramic FDPs, Everest(R) group was zirconia three-unit FDPs fabricated using the Everest(R) system (Kavo Dental GmbH, Biberach, Germany) and Rainbow(TM) group was zirconia three-unit FDPs fabricated using the Rainbow(TM) system (Dentium Co. Inc., Seoul, South Korea). They were cemented to resin dies with adhesive resin cement. After removing pontics, each retainers were separated and observed under measuring machine (Presize 440C) and analyzed through one-way ANOVA and Duncan test (alpha= .05). RESULTS: Mean values and standard deviations of marginal gap dimensions in each group for three-unit FDPs were 78.5 +/- 11.05 microm for the metal-ceramic group, 59.30 +/- 11.63 microm for the Everest(R) group and 70.34 +/- 13.98 microm for the Rainbow(TM) group. CONCLUSION: 1. The Everest(R) group in comparison with metal-ceramic group showed better marginal fit, which had significant differences (P<.05). 2. The mean marginal gap values between Everest(R) and Rainbow(TM) group did not showed significant differences (P>.05). 3. The mean marginal gap values between Rainbow(TM) group and metal-ceramic group did not showed significant differences (P>.05). 4. The mean marginal gaps of each group were within clinically acceptable range (120 microm).

Arthroscopic treatment of shoulder instability involves two techniques mainly, transglenoid suture technique and anterior anchoring system. However, anterior anchoring system has some disadvantages such as limited indication, high cost, technical difficulty and incapability to suture or reconstruct for all types of Bankart lesion. Disadvantages of transglenoid suture techniques are indirect suture tie, bump effect and possibility of the suprascapular nerve injury. The authors use modified transglenoid suture technique (Rhees method) for shoulder instability involving Bankart lesion, type II SLAP lesion and capsular laxity. The purpose of this study is to accurately describe the relationship between the major neurovascular structures and the pinning sites used in transglenoid suture technique (Rhees method). Placement of two or three arthroscopic Beath pinning sites was simulated in four fresh cadaveric shoulder specimens by placing Steinman pins into the glenoid rim under open field. The specimens were then dissected and the relationship of the pinning sites to the suprascapular nerve and suprascapular artery were recorded. In Bankart lesion repair, safe zone of pinning sites were 2 and 5 oclock in two portals in right shoulder, safe zone of pinning sites were 7 and 10 oclock in two portals in left shoulder. Safe direction of pinning was as possible as inferomedial side in scapula. In type II SLAP repair, safe zone of pinning sites were 2 oclock and just above 2 oclock of glenoid in right shoulder and 10 oclock and just above 10 oclock of glenoid in left shoulder. Safe direction of pinning was pararell to glenoid cavity and slightly superior in horizontal plane. From this study, these sites and directions appeared to be safe. Proper pinning depends on careful attention to the topographical anatomy about the shoulder.
