The effect of oral nicorandil were evaluated by a 9-day double-blind cross-over protocol on 16 subjects with angina pectoris referred to our cardiology clinic from June '84 through September '85. total daily doses were 15-45mg. The effects were measured by 3 seperate treadmill exercise EKG tests and symptom reviews on each patient. The following results were obtained. 1) The mean age of the patients was 57.4+/-7.2 years. These were 14 male and 2 female patients. 2) Resting heart rate on nicorandil was 73.6+/-14.0 beats/min and 70.5+/-14.0 beats/min in placebo(P<0.05). There were no significant effects of nicorandil on resting blood pressure and heart rate-blood pressure product. 3) Peak exercise heart rate was 126.4+/-22.5 beats/min on nicorandil and 121.8+/-21.4 beats/min on placebo(P<0.05). There were no significant effects of nicorandil on blood pressure after exercise and peak heart rate-blood pressure product(x10(-3)) after nocorandil was 20.2+/-5.0 and 18.9+/-4.6 on placebo(P>0.05). 4) Exercise duration was 485.8+/-107.7 sec on nicorandil and 423.3+/-101.9 sec on placebo(P<0.001). 5) The exercise duration was prolonged in 11 cases(68.7%), showed on change in 2 cases(12.5%), and shortened in 3(18.8%). 6) There were attacks of chest pain during placebo period in 2 cases, but none developed during nicorandil period. 7) Headache was noted in 2 patients, and in one of them, it was so severe as to discontinue nicorandil stydy. No other side effects were noted. In conclusion, additional therapeutic benefit can be obtained by nicorandil in patients with severe angina in spite of conventional antianginal agents already being administered.

PURPOSE: To evaluate the radiologic and clinical outcomes of AO type C pelvic ring injury and identify the prognostic factors. MATERIALS AND METHODS: We studied 53 patients who were treated for AO type C pelvic ring injury from January 2002 to February 2010. Mean age and mean follow-up duration were 42.4 years and 14 months, respectively. We had 8 cases of AO type C1-1, 19 cases of C1-2, 11 cases of C1-3, 6 cases of C2 and 9 cases of C3 injury. We analyzed type of fracture, displacement, method of fixation and associated injuries. Radiologic outcome was evaluated with Matta and Saucedo criteria and clinical outcome was evaluated using Majeed score. RESULTS: The average Majeed score was 86.2 distributing as 36 excellent cases, 15 good cases and 2 fair cases. Using radiologic Matta and Saucedo criteria, patients were divided as 31 excellent cases, 17 good cases and 5 fair cases. There was no significant difference between the outcomes of anterior, posterior and antero-posterior fixation. Neurologic injury was the reason for an unsatisfactory functional outcome. We identified two cases with complication, one with postoperative infection and the other with nonunion following anterior-posterior fixation. CONCLUSION: Satisfactory radiologic and clinical outcomes were obtained with open reduction and internal fixation in the management of AO type C pelvic ring injuries. Neurologic injuries affected the clinical outcome.

BACKGROUND: Association of arterial stiffness and osteoporosis has been previously reported in women. However, this association is still controversial for men. Therefore, we investigated correlation of arterial stiffness and osteoporosis by measuring brachial-ankle (ba) pulse wave velocity (PWV) and bone mineral density (BMD). METHODS: We reviewed medical charts of 239 people (women: 128, men: 111) who visited the Health Promotion Center, retrospectively. ba-PWV was measured by automatic wave analyzer. Lumbar spine (L1-L4) BMD and femur BMD were measured by dual energy X-ray absorptiometry. Metabolic syndrome was based on the National Cholesterol Education Program (NCEP)-Adult Treatment Panel (ATPIII) definition. Body mass index (BMI)>25 kg/m2 was used instead of waist circumference. RESULTS: In Pearson's correlation analysis, PWV and femur BMD (Neck, total) had a significant inverse relationship in men (r=-0.254, P=0.007; r=-0.202, P=0.034). In women, PWV and the L-spine, femur (Neck, total) had a significant inverse relationship. (r=-0.321, P<0.001; r=-0.189, P=0.032; r=-0.177, P=0.046) Age and PWV showed the greatest association in both men and women (r=0.46 P<0.001; r=0.525, P<0.001) In multiple regression analysis, the L-spine BMD and PWV had an independent relationship in women after adjusting for age, metabolic syndrome, BMI, smoking, drinking and exercise. (r=-0.229, P=0.015). No independent association was found between PWV and BMD in men. CONCLUSIONS: The association between arterial stiffness and BMD was confirmed in women. However, this association was not statistically significant for men.

BACKGROUND: Hepatocellular adenoma (HCA) is a rare benign tumor of the liver. A subtype classification of HCA (hepatocyte nuclear factor 1alpha [HNF1alpha]-mutated, beta-catenin-mutated HCA, inflammatory HCA, and unclassified HCA) has recently been established based on a single institutional review of a HCA series by the Bordeaux group. METHODS: We used histologic and immunohistochemical parameters to classify and evaluate eight cases from our institution. We evaluated the new classification method and analyzed correlations between our results and those of other reports. RESULTS: Seven of our eight cases showed histologic and immunohistochemical results consistent with previous reports. However, one case showed overlapping histologic features, as previously described by the Bordeaux group. Four cases showed glutamine synthetase immunohistochemical staining inconsistent with their classification, indicating that glutamine synthetase staining may not be diagnostic for beta-catenin-mutated HCA. HNF1alpha-mutated HCA may be indicated by the absence of liver fatty acid binding protein expression. Detection of amyloid A may indicate inflammatory HCA. HCA with no mutation in the HNF1alpha or beta-catenin genes and no inflammatory protein expression is categorized as unclassified HCA. CONCLUSIONS: Although the new classification is now generally accepted, validation through follow-up studies is necessary.

In 1974, Casson et. al. reported midfacial degloving approach to repair the midfacial bone fracture. After then, this approach has been used frequently to treat the lesions on nasal cavity, nasopharynx, facial plastic surgery and midfacial trauma. Midfacial degloving approach consists of 1) bilateral sublabial incision 2) complete transfixion incision/ septocolumellar incision 3) bilateral intercartilaginous incision 4) bilateral pyriform aperature incision. This approach provides proper access for midfacial bone structure without facial scar but has post-operative complications such as transient epistaxis, infraorbital nerve paresthesia and nasal crust. We treated three patients using midfacial degloving approach to correct traumatic deformity in midface area. In two patients, rhinoplasty with autogenous rib graft was done simultaneously. So we report these cases with review of literatures.

PURPOSE: This study was performed to evaluate the usefulness of volar plate fixation of dorsally displaced unstable distal radius fracture. MATERIALS AND METHODS: 48 patients with dorsally displaced unstable distal radius fracture were treated by volar plate fixation, between August 1993 and February 2003. Radial inclination, radial length and volar tilting were analyzed by radiographic evaluation. For clinical evaluation, the clinical ratings of Green and O'Brien were used. RESULTS: Radiographic analysis of extra-articular or non-comminuted intra-articular fractures (AO type A2, A3, and C1) demonstrated no significant differences in radial inclination, radial height and volar tilting between the immediate postoperative period and the last follow-up evaluation. However, in cases of comminuted intra-articular fractures (AO type C2), there were statistically significant differences. In clinical evaluation, 40 (83%) patients demonstrated excellent or good results based on the clinical ratings of Green and O'Brien. 32 (94%) of patients demonstrated excellent or good results in extra-articular (AO type A2 and A3) or non-comminuted intra-articular fractures (AO type C1) and 8 (57%) patients demonstrated excellent or good results in comminuted intra-articular fractures (AO type C2). The number of patients with complications was 4 (8%). Median nerve neuropathy developed in 2 patients, and hand and wrist stiffness in 2 patients. All cases achieved bony union. There was no implant failure or irritation. CONCLUSION: Volar plate fixation of extra-articular or non-comminuted intra-articular fractures (AO type A2, A3, and C1) was an effective treatment method for dorsally displaced unstable distal radius fractures. It provided stable fixation and allowed early postoperative rehabilitation.

The objective of present study was to compare the color stability of esthetic materials after application of fluoride varnishes. Esthetic restorative materials including composite resin (Filtek Z350 XT, 3M ESPE, MN, USA), resin modified glass-ionomer (RMGI, Fuji II LC, GC Co., Tokyo, Japan), and giomer (Beautifil Flow Plus F00, Shofu Inc., Kyoto, Japan) were used in this study. Cavity shield (3M ESPE, MN, USA) and V-varnish premium (Vericom, Seoul, Korea) were used as the fluoride varnishes. 30 samples of each restorative materials were prepared, which were divided into 10 each, among three groups. Group I were stored in distilled water, which were used as the control, Group II were applied with Cavity shield and Group III were applied with V-varnish premium. All specimens were stored in the distilled water at 60 ℃ for 30 days for the accelerated test. Samples were then subjected to colorimetric analysis. Data collected was statistically analyzed using one way ANOVA and Tukey's post-hoc test (p=0.05). The color change before and after application of varnish was observed in all experimental groups. Especially RMGI showed highest ΔE* value (p<0.05). The color change according to the accelerated test showed no significant difference in the varnish application group and the control group. Giomer and RMGI applied with Cavity shield showed more color change than V-varnish applied group, despite no significant differences. Present study concludes that color stability of esthetic restoration materials can be affected by application of fluoride varnish. Especially, RMGI showed a large color change compared to the composite resin and giomer, which suggested that careful attention should be paid to clinical application.

Background:
Proteinuria is a significant risk factor for progression of IgA nephropathy (IgAN) and has a positive correlation with severity of foot process effacement (FPE). We evaluated the relationship of FPE with proteinuria and histologic characteristics, including the Oxford classification.
Methods:
Patients who underwent renal biopsy and were diagnosed with IgAN at a single center were retrospectively reviewed. Patients aged less than 18 years and those with the possibility of secondary causes were excluded from the study. Subsequently, we evaluated the association between degree of proteinuria, severity of FPE, and histologic characteristics, including the Oxford classification and other immunofluorescence stains.
Results:
A total of 805 cases of renal biopsy was performed at our institution, and 327 patients were diagnosed with IgAN. Among them, 82 patients were excluded. Severity of FPE had an impact on the degree of proteinuria. Notably, the group with diffuse FPE had more than about 1.3 g/day of urine protein compared to those with rare FPE. Among the histologic characteristics, M1 score and immune deposition of IgG affected severity of FPE (hazard ratios [95% confidence interval], 1.90 [1.10 to 3.26], and 3.77 [1.66 to 8.54], respectively).
Conclusion
Severity of FPE had an impact on the degree of proteinuria and may be associated with the pathogenesis of IgAN.

Gastric MALT lymphoma usually presents with various endoscopic morphologic characteristics. The majority of the endoscopic findings of low-grade gastric MALT lymphoma reveal multiple and superficial erosions or ulceration with mucosal nodularity, but high-grade gastric MALT lymphomas show ulceroinfiltrative and fungating lesion. However, low-grade gastric MALT lymphoma that presents as advanced gastric cancer is very rare. We experienced a case of low-grade gastric MALT lymphoma with perigastric lymph node infiltration; it presented as advanced gastric cancer, and it was treated with H. pylori eradication and CHOP chemotherapy. So we report on this case along with a review of related literatures.
