The present report presents a case of dens invaginatus (DI) in a patient with 4 maxillary incisors. A 24-year-old female complained of swelling of the maxillary left anterior region and discoloration of the maxillary left anterior tooth. The maxillary left lateral incisor (tooth #22) showed pulp necrosis and a chronic apical abscess, and a periapical X-ray demonstrated DI on bilateral maxillary central and lateral incisors. All teeth responded to a vitality test, except tooth #22. The anatomic form of tooth #22 was similar to that of tooth #12, and both teeth had lingual pits. In addition, panoramic and periapical X-rays demonstrated root canal calcification, such as pulp stones, in the maxillary canines, first and second premolars, and the mandibular incisors, canines, and first premolars bilaterally. The patient underwent root canal treatment of tooth #22 and non-vital tooth bleaching. After a temporary filling material was removed, the invaginated mass was removed using ultrasonic tips under an operating microscope. The working length was established, and the root canal was enlarged up to #50 apical size and obturated with gutta-percha and AH 26 sealer using the continuous wave of condensation technique. Finally, non-vital bleaching was performed, and the access cavity was filled with composite resin.

PURPOSE: The purpose of this study was to investigate factors affecting on infertility-related quality of life in women undergoing assisted reproductive techniques focusing on depression and resilience. METHODS: With correlational survey design, 125 infertile women who were receiving inpatient and outpatient treatment in K university hospital in D city completed a structured questionnaire. RESULTS: There was a significant negative correlation between depression and resilience and between the depression and the quality of life. There was a significant positive correlation between resilience and the quality of life. The factors affecting on infertility-related quality of life were depression, burden of expenses, and relationship with husband which explained 48% in the quality of life. CONCLUSION: It is necessary to develop and apply nursing programs that include individual counseling and education for infertile couple. Social support including financial support and better environment for these women will be also essential.

Impact and process evaluations were performed in order to verify the effectiveness of a public health nutrition program developed for child-bearing aged women in Korea. Participants included 58 high school girls who were divided into two groups. Each group received four 50 - 60 minute nutrition education lectures regarding healthy eating, osteoporosis, constipation and nutrition labeling in every two weeks. Each session took 50 - 60 minutes. Regarding nutrition knowledge, there was a significant increase of degree of perception (p = 0.0004), but no change in degree of accuracy after implementation (p = 0.9522). Nutrition education was also effective in attitude change, showing more participants were ready to change their eating behaviors in terms of meal regularity (p = 0.0455) and less processed food intake (p = 0.0143). After implementing nutrition education, effective behavioral changes were observed in milk consumption (p = 0.0037) and meal regularity (p = 0.0882) as well as daily activity such as stair use (p = 0.0701). However, nutrition education had no effect on body mass index and perceived health status. In process evaluation conducted by a 9 item questionnaire, grand mean score was 4.17 +/- 0.72 out of 5. Proportion of items with scores higher than 4 ranged 68-91%. These results suggest that the nutrition education program used in this study was effective and useful. For a wider use of this program, more research was recommend for a strategy development of program diffuse.

BACKGROUND: Recently, the incidence of hepatitis A virus (HAV) infection has been increasing in Korea, and an outbreak among healthcare workers (HCWs) has also been reported. This study aims to evaluate the seroepidemiology of hepatitis A among HCWs at an 820-bed teaching hospital in Korea, thereby facilitating HAV vaccination for these HCWs. METHODS: In June 2009, we assessed the total immunoglobulins against the HAV in the serum samples of 907 HCWs by using VIDAS Anti-HAV Total (bioMerieux, France). RESULTS: Seropositivity for HAV significantly increased with age (P<0.001): 0% for < or =25 years, 9.4% for 26-30 years, 39.5% for 31-35 years, 66.7% for 36-40 years, 85.7% for 41-45 years, 96.0% for 46-50 years, 98.3% for 51-55 years, 95.8% for 56-60 years, and 100% for > or =61 years. CONCLUSION: Since HCWs aged 20-40 years show low seropositivity for HAV vaccination against hepatitis A should be considered in all these HCWs.

OBJECTIVE: The purpose of this study is to evaluate the efficacy of ferritin-folate-cyanocobalamin supplementation for prevention of anemia during pregnancy. METHODS: The authors conducted a clinical investigation on 50 pregnant women from 20th to 36th gestational weeks. The cobination of cyanocobalamin coenzyme 500mg, folic coenzyme 800mcg, and ferritin 20mg constituted the supplementation. The parameters examined in first trimester as baseline, before treatment(at 20th weeks), and after treatment(at 36th weeks) were : hemoglobin, hematocrit, ferritin, mean corpuscular hemoglobin(MCH), mean corpuscular hemoglobin concentration(MCHC), mean corpuscular volume(MCV), red blood cell count(RDW), folic acid, and vit. BPaired sample t-test was used for comparison. RESULTS: The results indicated a significant increase in the value of hemoglobin(p<0.05) and hematocrit(p<0.01) in comparison to before and after the treatment. The values of serum ferritin, folic acid, vitamin Bwere increased after the treatment compared to those of before the treatment, though there was no statistical significance. The results of MCV, MCH, MCHC, and RDW showed no statistically significant in comparison to before and after the treatment. CONCLUSIONS: These data indicate that supplementing ferritin 20mg-folate 800mcg-cyanocobalamine 500mcg per day from 20th to 36th weeks' gestation can increase values of hemoglobin, hematocrit, and ferritin concentration and can be cosidered as an appropriate method to prevent iron deficient anemia. It also might increase the value of folic acid and vitamin B12, concentration, but further study is stiU needed to determine whether the supplementation of folate and cyanocobalamine in combination with iron can have better eflicacy than iron alone in prevention of iron deficiency anemia.

Bodycomposition measurement is useful in the diagnosis of pathology, assessment of disease process and response to treatement in many endoclonologic and metabolic diseases. The Techniques used currently are mostly indirect, often expensive, difficult and time-consuming. A new method for estimation of body composition, infrared interactance, is rapid, safe, noninvasive, and may be useful in research and clinical studies. Body composition was assessed in 51 children and adolescants with insulin-dependent diabetes mellitus by infrared interactance method using a Futrex 5000A body fat content analyzer. Percentage body fat of pubertal girls was 26.1+/-7.6%, significantly greater than prepubertal girls (17.9%, 0<0.01) and pubertal boys (19.9%, p<0.05). Body fat content was increased through puberty in girls. but not increased in boys. Our data do not explain why body fat of pubertal boys was not increased. There was no significant association of insulin dose and HbA1C level with percentage body fat. Thus, we had to attempt measure calorie intake, activity level and diet composition. Our data revealed that dietary carbohydrates may prompt fat deposition, but energy balance does not explain the differences between pubertal girls and boys. In conclusion, Body fat increased through puberty in girls, but the etiology of differences in pubertal girls and boys is not clear, and in view of potential adverse effect of fat depostion of long-term health, further larger case-contolled study will be necessary.

Purpose: To evaluate the feasibility of pediatric low-dose facial CT reconstructed with filtered back projection (FBP) using adequate kernels. Materials and Methods: We retrospectively reviewed the clinical and imaging data of children aged < 10 years who underwent facial CT at our emergency department. The patients were divided into two groups: low-dose CT (LDCT; Group A, n = 73) with a fixed 80-kVp tube potential and automatic tube current modulation (ATCM) and standard-dose CT (SDCT; Group B, n = 40) with a fixed 120-kVp tube potential and ATCM. All images were reconstructed with FBP using bone and soft tissue kernels in Group A and only bone kernel in Group B. The groups were compared in terms of image noise, signal-to-noise ratio (SNR), and contrast-to-noise ratio (CNR). Two radiologists subjectively scored the overall image quality of bony and soft tissue structures. The CT dose index volume and dose-length product were recorded. Results: Image noise was higher in Group A than in Group B in bone kernel images (p < 0.001). Group A using a soft tissue kernel showed the highest SNR and CNR for all soft tissue structures (all p < 0.001). In the qualitative analysis of bony structures, Group A scores were found to be similar to or higher than Group B scores on comparing bone kernel images. In the qualitative analysis of soft tissue structures, there was no significant difference between Group A using a soft tissue kernel and Group B using a bone kernel with a soft tissue window setting (p > 0.05). Group A showed a 76.9% reduction in radiation dose compared to Group B (3.2 ± 0.2 mGy vs. 81.9 ± 11.1 mGy; p < 0.001). Conclusion The addition of a soft tissue kernel image to conventional CT reconstructed with FBP enables the use of pediatric low-dose facial CT protocol while maintaining image quality.
