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.

Holt-Oram Syndrome is an autosomal dominant disorder characterized by the association of upper-limb abnormalities and congenital heart disease. A woman with no family history of genetic disease underwent antenatal sonography at 27 weeks' menstrual age to screen for fetal anomalies. Ultrasonography revealed abnormalities in the upper limbs. The limb abnormalities included abscence of bilateral thumbs and radius: the left humus was short. Pregnancy termination was performed. The postnatal chromosomal analysis revealed a normal 46XX karyotype and the autopsy finding confirmed the Holt-Oram syndrome. We report a case of Holt-Oram Syndrome in fetus with unaffected parents with brief of the literatures.

OBJECTIVES: The purpose of this study was to investigate the relationship between restricted activity due to oral diseases and oral health behaviors among adolescents. METHODS: A cross-sectional study design was used. The subjects were 238 middle school students and 231 high school students; a total of 469 students from 15 different schools located in 7 regions of Bucheon in Gyeonggi Province, Daejeon, and others. The adolescents who participated in the survey were chosen by convenience sampling. The association between restricted activities due to oral diseases and oral health behaviors was analyzed using multiple logistic regression analysis. RESULTS: The annual experience rate of oral diseases stood at 1.4 percent, while the number of days absent and early departures from school was 0.15 days per student. The rate of middle school students who were disturbed by oral disease with respect to sleep, eating, speaking, and/or schoolwork was 33.1 percent. In high school students, it was 40.6 percent. Dental pain and gingival bleeding were identified as major factors to the restriction of activities, and being disturbed while eating was related to cariogenic beverages. CONCLUSIONS: It would be of great social interest to support and promote oral health programs among adolescents. Therefore, a national survey of the status of activity restrictions due to oral diseases in adolescents should be implemented in order to make specific future plans.

Anterior interosseous nerve syndrome is characterized by weakness of the flexor pollicis longus, the flexor digitorum profundus and the pronator quadratus in the presence of normal sensation. Although MR imaging findings of anterior interosseous nerve syndrome has been reported in a few articles, we report herein a case of anterior interosseous nerve syndrome involving more than usual muscles innervated by anterior interosseous nerve, caused by varient nerve innervation.

On July 6, 2009, an outbreak of gastroenteritis occurred among middle school students in Incheon. An investigation to identify the source and describe the extent of the outbreak was conducted. A retrospective cohort study among students, teachers, and food handlers exposed to canteen food in the middle school was performed. Using self-administered questionnaires, information was collected concerning on symptoms, days that canteen food was consumed, and food items consumed. Stool samples were collected from 66 patients and 11 food handlers. The catering kitchen was inspected and food samples were taken. Of the 791 people who ate canteen food, 92 cases became ill, representing an attack rate of 11.6%. Thirty-one (40.3%) of the 77 stool specimens were positive for Campylobacter jejuni. Interviews with kitchen staff indicated the likelihood that undercooked chicken was provided. This is the first recognized major C. jejuni outbreak associated with contaminated chicken documented in Korea.

Natural killer (NK) cell neoplasms are a group of rare but highly malignant tumors. We report here one case of NK cell leukemia. A 54-yr-old woman presented with a 2-month history of progressive left neck mass. Based on the positive result of tissue PCR for Mycobacterium tuberculosis, she was at first diagnosed with tuberculous lymphadenopathy. After two weeks, she developed generalized lymphadenopathy, hepatosplenomegaly, fever and anemia. Subsequent evaluation was performed including bone marrow aspiration and biopsy. Peripheral blood smear showed leukoerythroblastic features with 31% blasts. Bone marrow was packed with agranular blastoid cells, which were periodic acid-Schiff (PAS) positive and myeloperoxidase (MPO) negative. Immunophenotyping showed that these cells were positive for CD45 and HLA-DR, whereas negative for CD3, CD5, CD7, CD10, CD13, CD14, CD19, CD20, CD22, CD33, CD34, and CD61. Because of the absence of the markers of T-cell, B-cell, and myeloid lineage-specific antigens, we added CD16/56 for the immunophenotyping and the blasts were positive (94%). The tumor cells of biopsied lymph node were only positive for CD56, consistent with NK cell lymphoma. Epstein-Barr virus (EBV) was not detected by RNA in situ hybridization. Culture for M. tuberculosis was negative. Thus this patient was diagnosed with blastic NK cell lymphoma/leukemia involving bone marrow and lymph node.

The purpose of the study was to investigate the effects of lipid-coated ZnO (LCZ) and the level of LCZ compared with ordinary zinc oxide (ZnO) on antioxidant defense system in the intestine and liver of piglets. A total of forty piglets (n=8) were fed a diet supplemented with 100 ppm Zn with ZnO (ZnO-1), 2,500 ppm Zn with ZnO (ZnO-2), 100 ppm Zn as LCZ (LCZ-1), 200 ppm Zn as LCZ (LCZ-2), or 400 ppm Zn as LCZ (LCZ-3) for 14-d, respectively. The LCZ-3 group resulted in higher (P < 0.05) mRNA expressions and activities of CuZn-superoxide dismutase (SOD), glutathione peroxidase (GPX), catalase (CAT), and glutathione S-transferase (GST) in jejunal mucosa compared with the ZnO-1 and LCZ-1 groups, while no difference was observed in the mRNA level of antioxidant genes between the ZnO-1 and ZnO-2 groups. Within the LCZ groups, the LCZ level linearly and quadratically (P < 0.01) increased antioxidant enzymes in the jejunum. The maximum response of jejunal antioxidant enzymes to Zn supplementation was achieved by 400 ppm of LCZ. Hepatic mRNA expression of antioxidant enzymes was unaffected by Zn source and level, while hepatic SOD and GST activities were greater (P < 0.05) in the LCZ-3 group than in the ZnO-1 group. No difference was observed in lipid peroxidation of the jejunum and liver and the total antioxidant power of plasma among groups. In conclusion, a supplementation with 400 ppm of LCZ resulted in a maximum increase in antioxidant enzymes, indicating that LCZ may affect antioxidant defense system more profoundly than ZnO.

The variant terminal trunk of the superior mesenteric artery (SMA) could be confused with the ileocolic artery (ICA) as it runs on the right side of the superior mesenteric vein. If the variant ileal branch of SMA is mistaken for the ICA, unintentional ligation could cause long-segment ischemia in the ileum. We encountered a rare case of ileal ischemia caused by unintentional ligation of the variant ileal branch of the SMA during laparoscopic right hemicolectomy, which was confirmed by indocyanine green (ICG) angiography and hyperspectral imaging (HSI). Intraoperative real-time perfusion monitoring using ICG angiography and tissue oxygen saturation monitoring using HSI could help detect segments of hypoperfusion and prevent hypoperfusion-related anastomotic complications.

OBJECTIVES: The purpose of this study was to identify the status of dental care utilization among mothers and children from multicultural families and analyzing the related factors. METHODS: The subjects in this study were 131 mothers from multicultural families and 175 mothers from Korean (control) families who were selected by convenience sampling from the city of Nonsan. The dental care utilization among mothers and children from multicultural families and mothers and children from Korean families were compared. A questionnaire survey was conducted using the self-administration method for mothers from Korean families and by a face-to-face interviewing method for mothers from multicultural families. RESULTS: The proportion of subjects who visited the dentist's office in the past year was not different between the two groups of mothers. However, this proportion was lower in children from multicultural families than those from Korean families. The factors that influenced the visit to dental clinics were age and spouse's age among multicultural mothers and age, spouse's age, personal perceptions about oral health, and oral health concerns among Korean mothers. The factors that influenced dental clinic visits were mother's career, household income, education level of the mother, children's age, mother's dental clinic visits, mother's perception of children's oral health among multicultural children and father's age, marriage duration of parents, children's age, mother's dental clinical visit, and the mother's concerns about children's oral health among Korean children. CONCLUSIONS: Multicultural children visit the dental clinic a lot less than Korean children. Social economic factors such as household income, education level affect the use of dental clinic services by multicultural families.
