BACKGROUND: The purpose of this study was to estimate the economical impacts of surgical site infection (SSI) after general surgeries. METHODS: A prospective study was performed with the surgeries from September to December, 2002 and the SSI cases were collected based on the definitions of Centers for Disease Control and Prevention, The length of stay (LOS) and the hospital charge for the SSI group were compared with the non-SSI (NSSI) group by a matched cohort study for age, sex, operation procedure, and NNIS risk groups. RESULTS: There were 1,007 cases of surgeries and the 52 cases of SSI and the 26 cases have been matched. The LOS of the SSI group was 5.2 days longer than that of the NSSI group (P<0.05) which was significant, The injection and dressing meal, and total hospital charge were \157,562, \72,251, and \2,153,964 more in SSI group than those of NSSI group (P<0,05) for post-operation stay. The charge of medication and room in SSI group were \558,146 and \723,114 more than those of the NSSI group, but there were no significant difference. CONCLUSION: The SSI could increase the LOS and the hospital charge; therefore, this economic loss had an impact on the hospitals as well as the patients. To estimate the economic impacts of SSI precisely, however, further studies are needed to analyze and control other factors for the cost such as a type of surgery. In addition, the scope and setting of cost analysis should be expanded into the aspects of an individual, the hospital, and society.

BACKGROUND: The immune system is controlled by a complex network of regulatory mechanisms which include neurologic and psychological factors. Previous studies of psychopathological population and population challenged by significant life events have shown that high levels of anxiety and depression are associated with impaired cellular immunity. However, less is known about the psychoimmuological relevance of family function with the immune function In healthy population. The aim of the present study was to investigate the presence and direction of relationship between family function and cellular immunity. METHODS: Design : Cross sectional, observational study. Participants : 41 healthy adult males from a family medicine ambulatory care unit in a tertiary hospital completed a series of psychometric instruments that include the Family APGAR(Adaptation, Partnership, Growth, Affection, and Resolve), FACES III. In parallel, lymphocyte subset assay, lymphocyte proliferative responses to the mitogen concanavalin(ConA), interleukin 1-beta, interleukin-2 was analysed to assess cell-mediated immune function. RESULTS: Family adaptability was inversely correlated with total T cell, B cell counts, helper T cell(T,) and Iymphocyte proliferative response to low dose mitogen Con A(p<0.05). Family cohesion was inversely correlated with suppressor T cell(Ta) (p<0.05). In the lymphocyete proliferative response to low dose Con A stimulation, the extreme family showed the highest response compared to mid-range and healthy family(p<0.05). Relative to moderately dysfucntional family, severe dysfucntional family and healthy family had significantly higher lymphocyte proliferative responses to the high dose Con A(p<0.05). CONCLUSIONS: We suggest that family function could be related with immune function and it may impact on health and susceptibility to illness in helathy adult males. Further studies are required to elucidate the direction of relationship of family function and cellular immunity and the psychosocial mechanisms involved in the immune system.

PURPOSE: To compare and analyze trueness and precision of provisional crowns made using stereolithography apparatus and subtractive technology. MATERIALS AND METHODS: Digital impressions were made using a master model and an intraoral scanner and the crowns were designed with CAD software; in total, 22 crowns were produced. After superimposing CAD design data and scan data using a 3D program, quantitative and qualitative data were obtained for analysis of trueness and precision. Statistical analysis was performed using normality test combined with Levene test for equal variance analysis and independent sample t-test. Type 1 error was set at 0.05. RESULTS: Trueness for the outer and inner surfaces of the SLA crown (SLAC) were 49.6±9.3 µm and 22.5±5.1 µm, respectively, and those of the subtractive crown (SUBC) were 31.8±7.5 µm and 14.6±1.2 µm, respectively. Precision values for the outer and inner surfaces of the SLAC were 18.7±6.2 µm and 26.9±8.5 µm, and those of the SUBC were 25.4±3.1 µm and 13.8±0.6 µm, respectively. Trueness values for the outer and inner surfaces of the SLAC and SUBC showed statistically significant differences (P < .001). Precision for the inner surface showed significance (P < .03), whereas that for the outer surface showed no significance (P < .58). CONCLUSION: The study demonstrates that provisional crowns produced by subtractive technology are superior to crowns fabricated by stereolithography in terms of accuracy.

OBJECTIVE: To compare the pain-reducing effect of forest bathing alone versus forest bathing in combination with stretching and strengthening exercises in patients with chronic posterior neck pain. METHODS: Sixty-four subjects with posterior neck pain that had lasted more than 3 months were enrolled. They were randomly divided into a forest bathing alone (FBA) group and a forest bathing with exercise (FBE) group; each group included 32 subjects. All subjects from both groups walked every morning in the forest for about 2 hours for 5 days. In the afternoon, the FBE group did a stretching and strengthening exercise for about 4 hours; the FBA group had free time in the woods. Visual analog scale (VAS) on one day, VAS over the previous week, neck disability index (NDI), EuroQol 5D-3L VAS (EQ VAS) and index (EQ index), McGill pain questionnaire (MPQ), the number of trigger points in the posterior neck region (TRPs), and the range of motion of the cervical spine were evaluated on the first and last day of the program and compared between the two groups. RESULTS: The number of TRPs were significantly reduced in the FBE group compared with the FBA group (p=0.013). However, the other scales showed no significant difference between the two groups. CONCLUSION: When patients with chronic posterior neck pain underwent a short-term forest bathing (less than 7 days) program, FBE was more effective in the reduction of the number of TRPs than FBA. However, all other pain measurement scales we evaluated showed no statistically significant difference between the two protocols.

PURPOSE: We report a case of fundus albipunctatus discovered in a young patient. CASE SUMMARY: A 7.6-year-old female showed numerous small whitish-yellow flecks in the perimacular area and retinal periphery. Dark adapted 0.01 electroretinography (ERG) and dark adapted 3.0 ERG were profoundly reduced. At 26 months after the first visit, the best-corrected visual acuities were 1.0 right eye and 0.9 left eye. There were no pigmented lesions, atrophic lesions, or vascular abnormalities in the retina. Humphrey and Goldmann visual field tests were performed, but neither of the tests revealed any scotomas or other visual field defect. The number and size of characteristic numerous small whitish-yellow retinal flecks seemed almost unchanged. In spectral domain-optical coherence tomography (SD-OCT), the subretinal hyper-reflective lesions spanned the retinal pigment epithelium and the external limiting membrane. ERG showed improved dark adapted responses (dark adapted 0.01 ERG and dark adapted 3.0 ERG) after prolonged dark adaptation (2.5 hours). No family member showed any abnormal findings. CONCLUSIONS: Fundus albipunctatus is a rare disease in Koreans. We report a case diagnosed using fundus photography, SD-OCT, visual field tests, and ERG after prolonged dark adaptation (2.5 hours).

Lysimachia foenum-graecum has been used as an oriental medicine with anti-inflammatory effect. The anti-obesity effect of L. foenum-graecum extract (LFE) was first discovered in our screening of natural product extract library against adipogenesis. To characterize its anti-obesity effects and to evaluate its potential as an anti-obesity drug, we performed various obesity-related experiments in vitro and in vivo. In adipogenesis assay, LFE blocked the differentiation of 3T3-L1 preadipocyte in a dose-dependent manner with an IC50 of 2.5 microg/ml. In addition, LFE suppressed the expression of lipogenic genes, while increasing the expression of lipolytic genes in vitro at 10 microg/ml and in vivo at 100 mg/kg/day. The anti-adipogenic and anti-lipogenic effect of LFE seems to be mediated by the inhibition of PPARgamma and C/EBPalpha expression as shown in in vitro and in vivo, and the suppression of PPARgamma activity in vitro. Moreover, LFE stimulated fatty acid oxidation in an AMPK-dependent manner. In high-fat diet (HFD)-induced obese mice (n = 8/group), oral administration of LFE at 30, 100, and 300 mg/kg/day decreased total body weight gain significantly in all doses tested. No difference in food intake was observed between vehicle- and LFE-treated HFD mice. The weight of white adipose tissues including abdominal subcutaneous, epididymal, and perirenal adipose tissue was reduced markedly in LFE-treated HFD mice in a dose-dependent manner. Treatment of LFE also greatly improved serum levels of obesity-related biomarkers such as glucose, triglycerides, and adipocytokines leptin, adiponectin, and resistin. All together, these results showed anti-obesity effects of LFE on adipogenesis and lipid metabolism in vitro and in vivo and raised a possibility of developing LFE as anti-obesity therapeutics.
