We report a case of ciliated hepatic foregut cyst which was incidentally found in a 64 year-old man. The cyst, 6 cm in diameter, was unilocular, solitary and was located in the medial segment of left lobe, just below the Glisson's capsule. Microscopically, the cyst wall consisted of 4 layers; pseudostratified ciliated columnar epithelium, subepithelial loose connective tissue, smooth muscle bundles and an outermost fibrous capsule. Although cartilage or subepithelial sero-mucous glands were absent, the morphologic features of the cyst correspond with those of an incomplete form of brochogenic cyst.

BACKGROUND: Antistreptolysin O (ASO) has been widely used to diagnose Streptococcus Pyogenes infections and their sequelae, rheumatic fever and acute glomerulonephritis. Butt in some cases there is no elevation of ASO that it is necessary to add one or more tests detecting immune response to S. pyogenes.. The authors analyzed the distribution of antideoxyibonuclease (ADNase) B and antistreptolysin O (ASO) among the children of an elementary school in Seoul and calculated their upper limit of normal (ULN) value. METHODS: ADNase B concentrations were determined by nephelometry (Behring Nephelometer 100 Analyzer, Germany) on 236 sera of healthy elementary school children in Seoul. Throat cultures were taken at the same time to compare ADNase B lovels between S. pyogenes carriers and non-carriers. RESULTS: The distribution of ADNase B concentrations among school children ranged from 77 (detection limit) to 1616 IU/ml and the ULN was estimated to be 362 IU/mL. The carriers of S. pyogenes clad significantly higher ADNase B levels (mean 392 IU/ml) than carriers of non-group A beta-hemolytic streptococci (BHS, 236 IU/ml) oY non-carriers of BHS (234 IU/ml). The relationship between ADNase B (Y) and ASO (X) levels was Y=0.4X+173 (r2=0.209). CONCLUSIONS: The distribution of ADNase B levels showed no close correlation with that of ASO, and ADNase B test was considered to have additive value to ASO test for detecting S. pyogenes infection.

OBJECTIVES: The purposes of this study were to evaluate the relationship between therapeutic compliance and emotional variables in the patients on maintenance hemodialysis and to make a help in planning the treatment in order to promote the therapeutic outcomes. METHODS: Subjects consisted of 43 end-stage renal disease patients who had been treated with hemodialysis for more than one year. Hostility was measured with Cook-Medly Hostility Scale and depressive symptom, with beck Depression Inventory(BDI) and anxiety, with Self-rating Anxiety Scale of Zung(SAS). Serum potassium(K), and phosphorus(P) level, and interdialytic weight gain(IWG) were selected as compliance indices, for they were said to reflect the effect of diet, medication and salts restriction, respectively. RESULTS: (1) While the patients on hemodialysis got the scores within the normal range in their anxiety and hostility scale, they showed higher score of BDI than normal person, which was wtatistically significant. (2) Considering the relationship between therapeutic compliance and emotional variables, diet compliance was significantly associated with the emotional variables such as depression and anxiety. The relationship would be drawn with the equation listed below; Compliance Value=4.656 x (Depression) + 2.592 x (Anxiety)-0.13 x (Depression)x(Anxiety)-9.742 (3) When the patients were given a series of supportive psychotherapy for about 1 month, they showed the decrease in the scores of anxiety and depression scales, and the elevation in compliance value. However, there was no room for saving that the compliance ratio was improved, because of the limitation in the research methodology. CONCLUSION: Therapeutic compliance depended on between depression and anxiety among the emotional variables, the supportive psychotherapy was useful method to improved the therapeutic compliance.

BACKGROUND: Postoperative pain after a spinal laminectomy has very harmful effects on human physiology, and many people are trying to control it more easily and safely. There are controversies in methods used for controlling postoperative pain after a spinal laminectomy. The purpose of this study was to examine an effective way to control postoperative pain after a spinal laminectomy. METHODS: Ninety patients (ASA I-II, aged 40 to 70) scheduled for a spinal laminectomy were divided into three groups. In group A, we administered fentanyl 1,000 microgram and morphine 5 mg (mixed in 0.9% normal saline) using the continuous epidural infuser; in group B, we administered fentanyl 500 microgram and morphine 5 mg and 0.25% bupivacaine (mixed in 0.9% normal saline) using the continuous epidural infuser; in group C, we administered fentanyl 1,500 microgram and morphine 10 mg (mixed in 0.9% normal saline) using the continuous IV infuser. We compared effects between the continuous epidural infusion and the continuous intravenous infusion by using the visual analogue scale and side effects. RESULTS: There was no significant difference between continuous epidural infusion groups. When the continuous epidural infusion groups and the continuous IV infusion group were compared, there were significant differences in 3 hr, 6 hr, and 12 hr VAS scores (P < 0.01). The incidence of side effects was very low, and there was no significant difference in side effects between the continuous epidural infusion and the continuous IV infusion groups. CONCLUSIONS: It was found that continuous epidural infusion methods were more effective than the continuous IV infusion method, but none of them showed satisfactory postoperative pain control in the early periods.

Recently, the size of the globe has been considered to be an important factor in determining the amount of correction in strabismus surgery. We operated on 88 cases of basic exotropia after measuring the axial length using A-scan ultrasonography. The amount of correction was calculated from the axial length and angle of deviation in each case. At least 2 months postoperatively, 77 cases(87%) had less than 10 prism diopters eso or exodeviation. Favorable results can be expected by introducing the size of the globe in determining the amount of correction in strabismus surgery.

BACKGROUND: Liver failure due to ischemia-reperfusion injury is a serious problem in liver transplantation and radical wide resection of the liver. This injury is believed to be closely related to the generation of oxygen free radicals. Gabexate mesilate, a synthetic protease inhibitor, has an effect on the suppression of extracellular release of oxygen free radicals in the microvascular endothelium, as well as on protease inhibition. In order to understand the effects of gabexate mesilate on ischemia-reperfusion injury to the liver, we performed animal experiment with rats. METHODS: We divided the rats into two ischemia-reperfusion groups:the experimental group which received a 30 minutes ischemic injury along with the infusion of gabexate mesilate and a control group which received only the injury. Each group was subdivided into 4 sub-groups:ischemic injury only and ischemic injury plus 60, 120 or 180 minutes reperfusion injury. The test parameters were TNF-a and IL-6 in the serum, and superoxide dismutase(SOD), catalase, and malondialdehyde(MDA) in liver and lung tissues. RESULTS: The group receiving gabexate mesilate had a significantly higher level of liver SOD and liver catalase and a significantly lower level of liver MDA and lung MDA than the control groups. The TNF-a levels in the gabexate mesilate groups were significantly lower in the early phase, and a comparison of the IL-6 levels between two main groups yielded no significant results. The levels of lung catalase and SOD showed no significant difference between the two main groups. CONCLUSIONS: Protease inhibitor has the beneficial effect of liver ischemia-reperfusion injury suppression due to an increase in antioxidants or oxygen-free-radical suppression. The roles of TNF-a and IL-6 in liver reperfusion injury was not clear in our investigation. However, TNF-a might have an effect in the early phase. The mechanism of reperfusion injury to the lung in liver ischemia-reperfusion injury might be different from that to the liver.

The encapsulated hepatocellular (HCC) is a pathologic subtype of HCC. It is a well defined tumor that tends to grow slowly, and has a better prognosis than any other gross forms of HCC. Twenty surgically resected HCC were evaluated retropectively to correlate the thickness of pseudocapsules in pathology with those in computed tomography and ultrasound. At a histologic examination, pseudocapsules of seven cases were composed of two layers, an inner compact fibrous zone and outer loose fibrous zone interlaced with compressed liver parenchyma containing small vessels and newly formed bile ducts. Sonographic thickness and pathologic measurements of pseudocapsule relatively well correlated, but the former slightly overestimated the thickness of pathologic pseudocapsule (r=0.825, y=2.56x-1.23, P<0.05). On the other hand, thickness in CT and pathologic measurement did not correlate well. Thirteen cases showed one layer of pseudocapsule in which two cases were composed of thin layer of compact fibrosis and eleven cases composed of loose fibrosis. There were poor correlations in this group between thickness of pseudocapsules in pathology and those in images. Image overtly overestimated the thickness of the pseudocapsules in pathology. In conclusion, radiologic pseudocapsule of HCC may represent the compressed liver parenchyma as well as the fibrous pseudocapsule.

PURPOSE: Heart rate variability (HRV) is a tool used to measure autonomic nervous function; however, there is no evidence that it can be used to define sympathetic hyperactivity in men with lower urinary tract symptoms (LUTS). We suspected that LUTS would differ between sympathetic hyperactive and hypoactive patients. Therefore, we measured HRV and divided the LUTS patients into two groups, a sympathetic hyperactive group and a sympathetic hypoactive group according to the low frequency/high frequency (LF/HF) ratio and made clinical comparisons between the groups. METHODS: A total of 43 patients with symptomatic LUTS (International Prostate Symptom Score [IPSS] over 8) and 49 healthy volunteers were enrolled. No subjects had diseases that could affect the autonomic nervous system, such as diabetes or hypertension. Electrocardiographic signals were obtained from subjects in the resting state and HRV indexes were calculated with spectral analyses. We divided the LUTS patients into two groups by an LF/HF ratio of 1.9, which was the median value in the healthy volunteers, and compared the differences in clinical characteristics, IPSS, prostate-specific antigen (PSA), and transrectal ultrasound (TRUS) results. The parameters were compared by independent sample t-test by use of SPSS ver. 19. RESULTS: There were no significant differences in age, serum PSA, or volume of the prostate between the 2 LUTS groups. However, analyzing IPSS questionnaires between two groups showed that there were significant differences in mean of Q2 score (frequency) and storage symptom score ([Q2+Q4+Q7]/3) (P<0.05). CONCLUSIONS: We suggest that an imbalance of autonomic nervous system activity may be a factor that evokes varieties of symptoms in men with LUTS. LUTS patients with hypoactive sympathetic tone may suffer from frequency and storage symptoms.
