PURPOSE: There has been various reports on the inverse association between coffee consumption and serum gamma-glutamyltransferase(GGT) activity in the general population of Western countries. However, this association is uncertain in the communities in which coffee consumption is less popular. So we tried to identify this association in men of rural area in Korea. METHODS: We examined the association between coffee consumption and serum GGT activity in cross-sectional study involving 379 male population health examinees aged 40 years and older from rural areas in Kyungnam prefecture in Korea. Those who perceived their health status as poor were excluded. Possible confounding effects of age, body mass index, alcohol consumption and cigarette smoking were controlled by multiple regression analysis and analysis of covariance. RESULTS: In multiple regression analysis, serum GGT activity was positively associated with alcohol intake, body mass index(P<0.001) and was negatively associated with coffee consumption(P=0.022), whereas no significant association was observed in cigarette smoking(P=0.094). Adjusted serum GGT activity level at the coffee consumption level of 0, one and two or more cups a day was 37.6 U/l, 35.9 U/l and 26.8 U/l respectively(Ptrend=0.008). CONCLUSION: Decreased serum GGT activity appears to be associated with coffee consumption in men of rural area, and further studies on the interrelationships among coffee consumption, alcohol intake and obesity will be necessary.

Transarterial chemoembolization (TACE) is a common treatment for unresectable hepatocellular carcinoma (HCC). The most common complications after TACE are non-specific symptoms called post-embolization syndrome, such as abdominal pain or fever. Rare complications, such as liver failure, liver abscess, sepsis, pulmonary embolism, cholecystitis, can also occur. On the other hand, gallbladder perforation is quite rare. This paper reports a case of gallbladder perforation following TACE. A 76-year-old male with a single 9-cm-sized HCC underwent TACE. Five days after TACE, he developed persistent right upper quadrant pain and ileus. An abdomen CT scan confirmed gallbladder perforation with bile in the right paracolic gutter and pelvic cavity. Percutaneous transhepatic gallbladder drainage was performed with the intravenous administration of antibiotics. After 1 month, the patient underwent right hemihepatectomy and cholecystectomy. Physicians should consider the possibility of gallbladder perforation, which is a rare complication after TACE, when unexplained abdominal pain persists.

With the increasing use of primary hip arthroplasty for management of intertrochanteric fractures, firm fixation and union of the greater trochanteric (GT) fragment are required during hip arthroplasty for management of intertrochanteric fractures. Various methods have been suggested to address this issue. However, displacement of the GT is a frequent occurrence. We have introduced a cement-filling technique for performance of hip arthroplasty of the proximal femur for achievement of immediate firm fixation of the GT. Cement filling during performance of hip arthroplasty for management of femoral intertrochanteric fractures is a valuable technique for preventing displacement of the GT and to encourage early mobilization.

OBJECTIVE: Workload is known to affect the hypothalamus-pituitary-adrenal axis. Although many studies had revealed that job stress related factors could affect the neuroendocrine system among blue-collar workers, these studies had limitations as they had not evaluated the workload by objective methods which took into consideration individual physiological differences. This study was conducted to evaluate the effects of physical workload adjusted job stress on cortisol regulation by using objective tools for workers having various job tasks. METHODS: Among 110 foundry workers, shipyard workers, and fine machine assemblers for whom saliva samples were obtained, 102 without any past history of conditions that could affect hormonal regulation such as diabetes, and hypertension were included in this study. Among the 102 study participants, 15 workers whose saliva for morning or afternoon or heart rate monitoring data was not attained were excluded from the final analysis. Workload was evaluated by RHR (relative heart rate) using a heart rate monitor, and job stress was evaluated by Karasek's Job Content Questionnaire. Saliva samples were gathered during 8 - 9 am and 5 - 6 pm, and salivary cortisol levels were analysed by radioimmunoassay. RESULTS: After adjusting several variables which could effect cortisol secretion including job stress, among the higher RHR group morning salivary cortisol level was increased (beta=60.32, S.E.=26.35, p=0.0266), afternoon salivary cortisol level was decreased (beta=-7.43, S.E.=29.73, p=0.8044), and salivary cortisol level difference between morning and afternoon was increased (beta=72.10, SE=35.50, p=0.0509). CONCLUSIONS: As physical workload increases morning cortisol level, which is caused by the effect of arousal, and decreases afternoon cortisol level, which is caused by exhaustion, physical workload enlarges the width of diurnal cortisol variance. Therefore, physical exhaustion due to excessive workload could have adverse effects on the neuroendocrine system.

PURPOSE: We wanted to compare the clinical and radiological results of surgical treatment of acetabular both column fracture according to the fixation method. MATERIALS AND METHODS: Between 1986 and 2008, 55 patients who underwent surgical treatment for acetabular both column fracture were clinically and radiologically evaluated after a minimum follow-up of one year. Of 55 patients, 29 cases were operated with a cerclage wire or cable (group I) and 26 cases were operated with a plate and screw (group II). The surgical approach, the intra- and post-operative complications and the reduction quality were compared between the two groups. The clinical and radiological results were analyzed according to the criteria reported by Matta. RESULTS: There were 14 (48.3%)/20 (76.9%) cases of anatomical reduction, 12 (41.4%)/6 (23.1%) cases of imperfect reduction, 1/0 case of poor reduction and 2/0 cases of surgical secondary incongruence, respectively. Thirty three patients of 34 anatomically reduced patients showed excellent clinical results and the anterior and posterior combined approach was frequent in group I. There were no differences between the two groups for the complications, although intraoperative complication was more frequent in group II and postoperative complication was more frequent in group I. CONCLUSION: The clinical and radiological results of surgical treatment in patients with both column fracture were satisfactory in both groups. However, the concerns related to the surgical approach and complications will require a randomized prospective study.

Retinol binding protein 4 (RBP4) has been postulated to provide a new link between obesity and insulin resistance. We aimed to assess the relationship between serum RBP4 and insulin resistance by investigating serum RBP4 levels in children and adolescents according to degree of obesity and pubertal stage. A total of 103 (30 lean, 39 overweight, 34 obese) were evaluated for serum RBP4, adiponectin, insulin, glucose and lipid profiles. RBP4 levels of obese and overweight groups were higher than those of lean group. RBP4 level was higher in pubertal group than in prepubertal group. RBP4 was positively correlated with age, height, weight, body mass index (BMI), abdominal circumference, systolic blood pressure, fasting insulin, homeostatic model assessment of insulin resistance (HOMA-IR), total cholesterol and triglyceride, and inversely with adiponectin. In the multiple linear regression analysis, RBP4 was found to be independently associated with pubertal stage, BMI and triglyceride but not with HOMA-IR. In conclusion, serum RBP4 level is related with degree of adiposity and pubertal development. The association of RBP4 with insulin resistance is supposed to be secondary to the relation between RBP4 and adipose tissue in children and adolescents.

Eosinophilic gastroenteritis is an unusual disease characterized by eosinophilic infiltration of gastrointestinal tract, peripheral eosinophilia, and gastrointestinal symptoms. There are mucosal, muscular, and subserosal types, of which the subserosal type is the rarest. We experienced a 32-year old male patient with the subserosal type of eosinophilic gastroe-nteritis, who was presented with abdominal distension. The ascitic fluid revealed increased eosinophil count. With oral prednisolone, diarrhea and ascites rapidly disappeared and eosinophils in peripheral blood returned to normal. We report this case with a review of relevant literature.

BACKGROUND: It is known that HLA molecule can restrict specific IgE responses, but few studies have documented the association between HLA and sensitization to house dust mite(HDM). OBJECTIVE: To evaluate whether a specific HLA type can be a risk or protective factor for the development of HDM sensitivity. METHOD: Total 146 subjects were genotyped for HLA-DRB1 using PCR-SSP technique and HDM sensitivity, determined by skin prick test using two mite allergens, D. pteronyssinus (Dp) and D. farinae (Df). Subjects were grouped according to Dp or Df sensitivity and linkage analysis between HDM sensitivity and HLA-DRB1 genotype was performed. RESULTS: The data revealed higher allele frequencies of DRB1*07 in Dp or Df sensitive groups compared to insensitive groups (11.6% vs. 2.6% in Dp, 11.5% vs. 3.3% in Df group, p<0.05), but the other allele frequencies showed no difference. CONCLUSION: There was a significant association between HLA-DRB1*07 genotype and HDM sensitization. These results indicate that antigen presentation by HLA class II molecule restricts the development of specific IgE response to HDM.

BACKGROUND: Vimentin is the major intermediate-size filament in the cytoplasm of cells from mesenchymal origin. The HL-60 cell is a unique human leukemic cell line capable of terminal differentiation with several chemical inducers, and then the cell line becomes a fre#quently described model system for cell differentiation in vitro. Vimentin mRNA is reduced during all-trans retinoic acid (retinoic acid) -dependent differentication but increased by 12-0-tetradecanoylphorbol-13-acetate (TPA). In this paper, we have investigated on the mechanism of transcriptional repression of vimentin gene during retinoic acid-dependent differentication of HL-60 cell. METHODS: HL-60 cells were grown in RPMI 1640 medium supplemented with 10% heat-inactivated fetal bovine serum and antibiotics in a humidified 5% CO at 37C. Total RNA was prepared by a modification of the method of Karlinsey et al. Northern blot hybridization was performed by the method of Virca et al. EcoRI fragment of pVIM-GEM was used as probe for vimentin mRNA. DNA mobility shift assay was performed by the method of Lim et al. End labeled DNA probe (Upper strand, 5-CGCITGATGAGTCAGCCG-3) for AP-1 binding activity was mixed with nuclear extracts in a 20 pL reaction volume containing 300 mM KCI, 60 mM HEPES, pH 7.9, 25mM MgC1, 1mM EDTA, 1mM DTT, 60% glycerol, and 2 pg of poly[dI-dC]. RESULTS: The level of vimentin mRNA was decreased at 12 hours after retinoic acid treatment, and not detected at 48 hours. The level of vimentin mRNA was reduced in proportion to concentration of retinoic acid, Retinoic acid-reduced vimentin mRNA was no change in cells treated with cycloheximide. Retinoic acid-dependent decrease of vimentin mRNA was partially recovered by staurosporin pretreatment. In DNA mobility shift assay, AP-1 binding activity was reduced at 48 hr during retinoic acid-induced differentiation. CONCLUSION: These results suggest that the transcriptional repression of vimentin gene during retinoic acid-induced differentiation in HL-60 cells is correlated with reduction of DNA binding activity of AP-1.
