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.

We report a case of colonic type-papillary adenocarcinoma of appendiceal origin in a 73-year-old male patient. The patient presented with right lower quadrant mass and was operated for a preoperative diagnosis of inflammatory small bowel mass. The mid one-third of the appendix showed a 3.5x3.3 cm sized, broad-based, intraluminal papillary mass. Microscopically, it was a well differentiated papillary adenocarcinoma and revealed a strong immunoreactivity to carcinoembryonic antigen. Tumor desmoplasia and acute inflammatory change were prominent.

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.

OBJECTIVE: The purpose of this study was to measure and compare temporal lobe volumes of geriatric depressive patients and normal controls. Temporal lobe volume was measured with computerized volumetric technique using brain MRI films. METHOD: We studied 15 patients of 50 years or older with major depressive disorder (MDD) and 14 normal control subjects, measured temporal lobe volumes and cerebral volumes of both groups using semi-automated imaging analysis program from brain MRI films. A statistical analysis was done to compare right and left volumes in both groups and to compare right and left volumes in each group. The comparison of right and left volumes between early-onset MDD group and late-onset one and correlation with duration of illness of MDD group were taken too. RESULTS: There was no difference in right and left temporal volumes between MDD group and normal control (right p=.760, left p=.219) but there was statistically significant difference between right and left volume in normal controls who have larger right temporal lobe volume than left temporal lobe volume (p=.002) compared to MDD patients who have no difference between right and left temporal lobe volume (p=.644). In MDD patients, there were no difference between early-onset MDD group and late-onset one and no correlation of volume with duration of illness. CONCLUSION: This study aiming at identifying the structural change of brain in geriatric depressive patients did not reveal any difference of temporal lobe volume between MDD patients and normal controls, and between right and left temporal lobe in geriatric MDD patients. The loss of laterality in patients was partially identical with the previous results of other studies, so it needs further following studies which have larger size of subjcets with various implicated variables and more fine brain structures.

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.
