BACKGROUND/AIMS: Gastric carcinoma is the most common malignant neoplasm in Korea and is known to be associated with intestinal metaplasia (IM) of gastric epithelium, of which type III IM is suggested to play a special role in the carcinogenesis. This study is to evaluate the subtypes of IM and to measure each subtype in chronic gastritis. Methods: From October 1997 to September 1999, 321 patients with endoscopic chronic gastritis were evaluated the grade of chronic gastritis and IM by histologic and histochemical stain. RESULTS: Chronic inflammation and IM were remarkably severe in men and Helicobacter pylori (H. pylori) positivity was 69.4% in men and 65.2% in women. The frequency of IM was 50.1%, of which 65.4% was in men and 34.6% in women. The frequency of IM subtypes was 43.2%, 11.7% and 45.1% for type I, II and III respectively. Sixty percent of IM was noted in more than 50 years of age and ninety percent in more than 40 years of age. The frequency of type III IM was 61.6% in men and 38.4% in women. Sixty one percent of type III IM was noted in more than 50 years of age and ninety percent in more than 40 years of age. Interestingly, fifty three percent of type III IM was noted in men more than 40 years of age. The prevalence of H. pylori infection in type III IM was similar to in type I and II. The glandular atrophy in type III IM was remarkably severe than that in type I and II. Conclusions: The results of this study show that the proportion of type III IM in chronic gastiritis is remarkably high in Korean and age and sex distribution is similar to that of gastric carcinoma.

PURPOSE: The antibodies for minichromosome maintenance(MCM) proteins have been reported as potential proliferative markers and prognostic indicators in various human malignancies. The present study examined the expression pattern of MCM proteins in bladder carcinomas, and we also evaluated their prognostic significance as well as their potential applicability as proliferation markers. MATERIALS AND METHODS: Immunohistochemistry for MCM7 and Ki-67 was performed on paraffin sections from 47 cases of bladder carcinoma. The MCM7 and Ki-67 expressions were quantified and then analysis was carried out for determining the association between the expressions of MCM7 and Ki-67 and the clinicopathological parameters. RESULTS: A significant correlation existed between the expression rate of MCM7 and the histological grade(p<0.0001). The Ki-67 expression rate was significantly related to the tumor grade(p=0.002) and the pathological stage(p=0.011). On multivariate analysis, MCM7 was not found to be an independent prognostic factor for predicting the recurrence of bladder carcinoma. CONCLUSIONS: The results suggest that MCM is a reliable proliferation marker, but not an independent predictive factor for recurrence of bladder carcinoma.

Purpose:
To compare efficacy of ultrasound (US)-guided single-injection nerve blocks (SINB) before bipolar hemiarthroplasty (BHA) of the hip in patients with femoral neck fractures.
Materials and Methods:
Clinical outcomes of 89 patients who underwent BHA between September 2016 and February 2018 were retrospectively compared. Eight patients were excluded according to exclusion criteria and the remaining patients were divided into two groups: patients who received SINB before surgery (Group I; n=40), and patients who did not (Group II; n=41). The femoral, obturator, and lateral femoral cutaneous nerves were each blocked separately under US guidance. Pain scores determined using the visual analogue scale (VAS) were recorded 6, 12, 24, and 48 hours postoperatively, and all use of analgesics were recorded separately for 72 hours after surgery. Duration of hospitalization, general complications, and local complications due to SINB were also compared among the groups.
Results:
Significant differences were observed between the two groups: I) VAS at 6 hours and at 12 hours after the operation, II) total amounts of analgesics used. VAS at 24 hours and at 48 hours were not significantly different between the two groups. General complications and duration of hospitalization were also not significantly different between the groups.
Conclusion
US-guided lower limb nerve blocks provide excellent immediate postoperative pain relief and can be used as a safe, and effective method of pain control after BHA.

PURPOSE: Nonunion of intra-articular fractures of calcaneus is rarely reported complication. We present our experiences with 4 patients (5 cases) treated operatively for nonunion after intra-articular fracture of calcaneus. MATERIALS AND METHODS:4 patients (5 cases) with nonunion of intra-articular fracture of calcaneus after operative treatment were followed for 4 years (from 2002 to 2006). For assessment, the American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot score and Visual Analogue Scale (VAS) were assessed for clinical outcome and the union of fracture site, the talocalcaneal height and the angle of talar declination were determined for radiologic outcome. RESULTS:The mean talocalcaneal height was 6.94 cm (range, 5.9~7.6 cm) preoperatively and 7.34 cm (range, 6.0~8.3 cm) at last follow-up. The mean angle of talar declination was 5.68 degrees (range, 4.6~8 degrees) preoperatively and 13.1 degrees (range, 5.7~21 degrees) at last follow-up. The mean preoperative AOFAS score and VAS were 20.4 (range, 14~36) and 4 (range, 3~6), respectively. At last follow-up, these scores improved to a mean of 59.6 (range, 54~68) and 3 (range, 2~4), respectively. Unions of previous nonunion site of intra-articular fracture of calcaneus were achieved in all 4 patients (5 cases). CONCLUSION: The reconstructive procedure for nonunion of intra-articular fracture of calcaneus showed good results in terms of bone union, radiologic results and functional improvement than preoperative state. Because the plantar pain for the inferior angular formation in nonunion site may happen, we will pay attention to reduction of fragment.

BACKGROUND: Visceral obesity is the most powerful contributor to the development of metabolic syndrome (MetS) and cardiovascular diseases. In light of visceral obesity, however, there is a paucity of data on the appropriate cutoff point of waist circumference (WC) in subjects with type 2 diabetes. The aim of this study was to investigate the optimal cutoff value for WC that signals insulin resistance (IR) and visceral obesity in Koreans with type 2 diabetes. METHODS: We evaluated 4,252 patients with type 2 diabetes (male 2,220, female 2,032, mean age 57.24 years) who visited our clinic between January 2003 and June 2009. WC was measured at the midpoint between the lower rib and the iliac crest, and insulin sensitivity was assessed by the rate constant of plasma glucose disappearance (Kitt %/min) using an insulin tolerance test. Visceral fat thickness was measured using ultrasonography. Statistical analysis was performed using receiver operating characteristic curve. RESULTS: The optimal cutoff points for WC for identifying the presence of IR and visceral obesity, as well as two or more metabolic components, were 87 cm for men and 81 cm for women. Moreover, these cutoff points had the highest predictive powers for the presence of visceral obesity. The MetS defined by new criteria correlated with the increased carotid intima-media thickness in female subjects. CONCLUSION: Our results suggest that the optimal cutoff values for WC in Koreans with type 2 diabetes should be reestablished based on IR and visceral obesity.
