Therapeutic irradiation can induce angiosarcoma. Radiation-induced angiosarcoma constitutes 20% of all angiosarcomas. Although its common site of origin is the skin and subcutaneous tissue, it rarely arises in small or large bowels with a presentation as multifocal abdominal angiosarcomatosis. We report a case of intra-abdominal angiosarcomatosis involving the jejunum, ileum, transverse colon, mesentery and right ovary in a 63-year-old female. It developed 10 years after therapeutic irradiation for squamous cell carcinoma of uterine cervix. She developed panperitonitis due to intestinal perforation. She died from sepsis 3 days after segmental resection of the small bowel and right oophorectomy. We reviewed the previously reported cases and describe the clinicopathologic features of this tumor.

OBJECTIVE: In order to compare and find the HRQOL and it's determinants among occupationally injured workers, TA patients and general workers, we performed a crosssectional study in Masan and Changwon city, Korea. METHODS: Cases were 169 occupationally injured workers who admitted in the hospital, and controls were 78 TA patients who admitted in the hospital and 166 general workers who worked at Ulsan industrial area. HRQOL were measured by SBQOL. We investigated confounding variables which were age, sex, marital status, employment status, family numbers, monthly income, diagnosis, treatment duration, expectation for health recovery, and expectation for return to work. We compared the HRQOL among occupationally injured workers, TA patients and general workers. We made four factors from twenty three items by factor analysis and used multiple logistic regression to find determinants on HRQOL in each group. RESULTS: There were significant differences in HRQOL between case and control. The main determinants on HRQOL from multiple logistic regression varied in each group. In occupationally injured workers, age(OR 2.73), treatment duration(> 6 months) (OR 3.09) and expectation for return to work(OR 2.62) were main determinants for HRQOL. And age(OR 1.07), marital status(OR 7.41), family members(OR 5.73), expectation for health recovery(OR 4.23) in TA patients. However, monthly income (<1,300,000 won)(OR 1.76) were main determinants for HRQOL in general workers. CONCLUSION: Return to work is major determinants of HRQOL for occupationally injured workers.

Necrotizing periodontal diseases, especially acute necrotizing ulcerative gingivitis (ANUG), it should be noted, occur abruptly and progress rapidly, eventually causing severe soft-tissue and alveolar bone loss. This report presents the cases of two ANUG patients and provides a brief treatment protocol for easy and effective clinical management. After proper diagnosis, sequential treatment with cessation of mechanical brushing, along with a prescription of systemic antibiotics and chlorhexidine as a mouth rinse, scaling, root planing, and supportive periodontal therapy, was utilized. In all cases discussed in this report, there was marked improvement in a few days. ANUG, though an uncommon disease, can be efficiently managed with proper diagnosis and immediate treatment.

OBJECTIVE: To test if the intake of H2 receptor antagonists (H2-RAs) increases the risk of gastric cancer in the elderly. METHODS: The source population for this study was drawn from the responders to a questionnaire survey administered to the Korea Elderly Pharmacoepidemiological Cohort (KEPEC), who were beneficiaries of the Korean Medical Insurance Corporation, were at least 65 years old, and residing in Busan in 1993. The information on H2-RAs exposure was obtained from a drug prescription database compiled between Jan. 1993 and Dec. 1994. The cases consisted of 76 gastric cancer patients, as confirmed from the KMIC claims data, the National Cancer Registry and the Busan Cancer Registry. The follow-up period was from Jan. 1993 to Dec. 1998. Cancer free controls were randomly selected by 1:4 individual matching, which took in to consideration the year of birth and gender. Information on confounders was collected by a mail questionnaire survey. The odds ratios, and their 95% confidence intervals, were calculated using a conditional logistic regression model. RESULTS: After adjusting for a history of gastric ulcer symptoms, medication history, and body mass index, the adjusted OR (aOR) was 4.6 (95% CI=1.72-12.49). The odds ratio of long term use (more than 7 days) was 2.3 (95% CI=1.07-4.82). The odds ratio of short term use was 4.6 (95% CI=1.26-16.50). The odds ratio of parenteral use was 4.4 (95% CI=1.16-17.05) and combination use between the oral and parenteral routes (aOR, 16.8; 95% CI=1.21-233.24) had the high risk of gastric cancer. The aOR of cimetidine was 1.7 (95% CI=1.04-2.95). The aOR of ranitidine was 2.0 (95% CI=1.21-3.40). The aOR of famotidine was 1.7 (95% CI=0.98-2.80). CONCLUSION: The intake of H2-RAs might increase the risk of gastric cancer through achlorhydria in the elderly.

BACKGROUNDS/OBJECTOVES: Family has an impact on dietary intake of children as a proximal food environment and family structures are changing and becoming more diverse. This study was performed to identify the association between family structure and food group intake of children aged 3-18 years in Korea. SUBJECTS/METHODS: A total of 3,217 children with complete data on variables for household information, dietary intake and sampling weights were obtained from 2010-2011 Korea National Health and Nutrition Examination Survey. Children's family structure was classified into 3 groups (Living with both parents, Living with one parent and Living without parents). To evaluate children's food group intake, scores of individual food groups ('Grains', 'Meat, Fish, Eggs and Beans', 'Vegetables', 'Fruits' and 'Milk and Dairy products') was calculated from percent adherence to the recommended servings of the Korean Food Guidance System (KFGS). 'Food group mean score' was obtained by calculating the average of five food group scores. RESULTS: After adjusting for age, sex, number of family members, and household income, children living with both parents had higher scores in 'Fruits' (P < 0.01), 'Milk and Dairy products' (P < 0.05), and mean score of individual food group score (P < 0.001) compared to children living with one parent. Individual food group scores and mean scores of individual food group scores were associated with different socio-demographic factors in study children. Family structure was associated with 'Fruits,' 'Milk and Dairy products' score and mean scores of food group scores. CONCLUSIONS: These results suggested that different approach might be required to solve nutrition problem in children depending on their family structure and other socio-demographic factors.

PURPOSE: The aim of this clinical trial was to explore the impact of intentional passive eruption (IPE) using occlusal reduction on the periodontal parameters of teeth with moderate chronic periodontitis and traumatic occlusion. METHODS: This study was performed on 40 teeth from 16 subjects. At baseline, 4 weeks after initial periodontal treatment, and 6 months after IPE, clinical and radiographic examinations were performed. The 20 teeth in the test group underwent IPE using occlusal reduction, whereas the 20 control teeth did not undergone occlusal reduction. RESULTS: All the periodontal parameters were improved by the initial periodontal treatment. The teeth in the test group showed a significantly greater decrease in pocket depth, tooth mobility, and marginal bone loss than did the control group (P<0.05), but there were no significant changes in the attachment level. Significantly greater improvements in all the parameters were observed in the test group after 6 months of IPE compared to 4 weeks after the initial periodontal treatment (P<0.05). CONCLUSIONS: Within the limits of this study, performing initial periodontal therapy combined with IPE using occlusal reduction was shown to be very simple and effective. Moreover, IPE would be helpful in improving periodontal parameters.

Adenocarcinoma of the ciliary epithelium is a rare tumor, usually occuring in elderly patients who have a history of severe ocular trauma or chronic inflammation. We report an adenocarcinoma of the nonpigmented ciliary epithelium found within the phthisical globe of a 36-year-old female whose eye had been loss of vision since infancy. The mass, measured 4.0 x 4.0 cm, was relatively limited by sclera but had invasion to posterior portion. Histologically, the tumor was a compact mass which consisted of tubular and papillary structures with foci of the pleomorphic area. Strands of cells and individual cells were invested with thick basement membrane that have positivity for periodic acid-Schiff stain. Immunohistochemical staining showed strong reactivity for cytokeratin and epithelial membrane antigen, and focal for neuron-specific enolase and S-100 protein.

The atrophy of edentulous ridge and pneumatization of the maxillary sinus often limit the volume of bone available for implant placement on maxillary posterior teeth. Most clinicians suffer difficulties from poor bone quality and quantity on maxillary posterior site. Thus, the success of maxillary posterior implant surgery depends on the increase of the available bone and obtaining a good initial stability of the implant after maxillary sinus reconstruction. The maxillary sinus augmentation methods include a crestal approach and a lateral approach. Less morbidity and complications after operation is major advantage to sinus augmentation using crestal approach than lateral approach. However, when the residual ridge height is ≥ 6 mm, it is known that crestal approach is appropriate. Also delayed implantation after sinus augmentation is recommended in severely atrophic ridge. We present the three cases of implant placement simultaneously sinus augmentation using crestal approach in posterior maxilla site with ≤ 3 mm of residual alveolar bone.
