PURPOSE: To illustrate frequently encountered anatomic variations on PNS computed tomography(CT) and to assess their clinical significance. MATERIALS AND METHODS: CT findings of 1523 patients, who underwent PNS CT with no history of sinus surgery, were reviewed, and prevalence of each anatomic variation and its relationship with mucociliary clearance pathway was evaluated. RESULTS: Two categories of anatomic variations were encountered. The first group included variations of the turbinates, such as concha bullosa(28.6% ), paradoxical middle turbinate(31.5%), of the uncinate process, such as medially bent or folded(36.3%), laterally bent(3.7%) or uncinate bulla(0.5%), of the ethmoidal sinus, such as Haller's ce11(28.2%), large agger nasi ce11(9.6%) or large ethmoidal bulla(23.5%) and nasal septal deviation(24. 1%), which might cause obstruction of mucociliary clearance pathway and thus give rise to secondary obstructive sinusitis. The second group included Onodi ce11(1.4%) and medial depression of the lamina papyracea (3.5%), which were not related with obstructive sinusitis. 87 cases of large agger nasi cell were associated with obstruction of nasofrontal recess. Large ethmoidal bulla(452 cases), Haller's ce11(245 cases) and true concha bullosa (25 cases) contributed to narrowing of the infundibulum. Medially bent uncinate process(220 cases), concha bullosa(157 cases), paradoxical middle turbinate(126 cases) and nasal septal deviation(93 cases) were observed in middle meatal obstruction and supreme concha (3 cases) accompanied sphenoethmoidal recess obstruction. CONCLUSION: Recognition of anatomic variations on PNS CT is important to build a treatment plan in patients with obstructive sinusitis as they may represent causes of the disease, and to avoid critical complications during functional endoscopic sinus surgery.

PURPOSE: To evaluate the incidence and CT findings of the medial depression and bony dehiscence of lamina papyracea as an anatomic variation. MATERIAL AND METHODS: 1472 PNS CTs of the patients with symptoms of chronic sinusitis were retrospectively evaluated. RESULTS: The total incidence of depressed lamina papyracea as an anatomic variation was 3.5%(52/1472) on PNS CT. There was a statistically significant correlation between the increasing age and the incidence of delamina papyracea. Depression of lamina papyracea anterior to the basal lamella were more common those of the posterior depression. Associated findings were herniation of adjacent fatty tissue in all cases and the roedial bowing and hypertrophied configuration of the medial rectus muscle without significant herniation in 19 cases(34%). CONCLUSION: Nontraumatic, asymptomatic depression with bony dehiscence of lamina papyracea as an anatomic variation is not uncommon with the incidence of 3.5%. Recognition of its existence and degree may helpful in avoiding various ocular complication during ethmoid surgery.

BACKGROUND/AIMS: Chronic hepatitis C virus (HCV) infection is often associated with extrahepatic autoimmune disease, and autoantibodies such as anti-nuclear antibody (ANA) or anti-smooth muscle antibody (ASA). The presence of autoantibodies may make discrimination between chronic hepatitis C with autoimmune features and type 1 autoimmune hepatitis difficult. We studied the prevalence of autoantibodies in patients with chronic HCV infection and their clinical significance. MATERIALS AND METHODS: ANA, ASA, anti-mitochondrial antibody (AMA), anti-microsomal antibody (AmA), rheumatoid factor (RF), anti-cardiolipin antibody (aCL) and lupus anti-coagulant (LA) were tested in 116 patients (80 chronic hepatitis C, 36 liver cirrhosis). Genotypes of HCV were determined in 25 patients by INNO LiPA. RESULTS: The overall prevalence of autoantibody was 65.5%. The most common autoantibody was aCL (34.5%), followed by ANA (25%), RF (18%), LA (15.5%), ASA (6.9%), anti-microsomal antibody (6%) and AMA (1%). The positive rate of either ANA or ASA was 30.2%, but both were positive in 1.7% only. There was no difference in the demographic features, biochemistry, HCV genotypes and disease status between autoantibody-positive and autoantibody-negative patients. CONCLUSIONS: Autoantibodies were commonly found in patients with chronic HCV infection. But, the presence of autoantibodies may be a non-specific finding in chronic hepatitis C infection without clinical significance.

In the complexity and diversity of modem society, there is an urgent need for an information system which can systematically collect, manage and analyze data. The purpose of this paper is to find the relationship between traits of medical and non-medical staffs with indicators of computer-related effectiveness. In order to fulfill this purpose, dependent and independent variables are extracted from previous findings, and hypotheses are formulated. To test these hypotheses we carried out field research. The sample size which we studied is 203 employees of a general hospital in Taegu. Some of the meaningful findings of this study are as follows: The educational level has a positive relationship with computer usage time. And the attitude about computers has a positive relationship with degrees of satisfaction. Nurses' group especially has the most positive relationship with degrees of satisfaction, and physicians' group, resident doctors' group, pharmacologists' group, non-medicals' group(administrative etc.) are ranked in order of satisfaction.

Hand injury in children was increased due to multiple environmental risks and failed attention of parents to children in rapidly developing society. By the results of this evaluation in 37 cases, it was summarized as follows. First, hand injuries in children most commonly occurs in spring, and occurs more commonly in the children at the age of high activity. The most common level of injury is zone I by microreplantation zone, and zone II by tendon injury zone. The more desirable results were obtained by full thickness skin graft and composite graft if it were possible. For the better functional results compare to adults, the methods and procedures must be constructed after more evaluation with more clinical cases. In the cases of pediatric hand injury, the most important fact is prevention of injury, with the close attention by parents, and the second is appropriate diagnosis and treatment for more functional results.
