An epidemiological investigation was conducted on Metagonimus yokogawai infection in Hadong Gun (County), Gyeongsang Nam Do, Korea, and following findings were obtained. Overall prevalence rate of Metagonimus yokogawai infection was 29.1 percent from a total of 1,163 inhabitants examined. By area of river and stream, Seomjin-gang R.: 9.5 percent (out of 95 inhabitants examined) in Jeondo Ri in the lower river, 19.9 percent (156) at Dugog Ri near Hadong town, and 90.8 percent (65) in Tab Ri of Hwagae Myeon where Hwagae-cheon Stream joins; Hwagae-Cheon Stream: 42.2 percent (45) in Yonggang Ri of the middle stream and 27.5 percent (72) in Daeseong Ri of the upper stream; Hoengcheon-gang R.: 54.7 percent (161) in Gojeol Ri of the lower river, 40.6 percent (128) in Hoengcheon Ri of the middle stream, and 5.4 percent (93) in Jungi Ri of the upper stream, and 43.8 percent (89) in Uge Ri located along a tributary of the Hoengcheon-gang R. and 4.0 percent (101) in Jangam Ri which is located about 4 km away from the river; Deogcheon-gang R.: 18.5 percent (54) in Munam Ri; Gwangog-cheon Stream: 2.8 percent (107) in Gwangog Ri. The difference in prevalence rate of the infection by area was correlated with the opportunity and amount of raw eating of sweetfish by the inhabitants in the respective areas. By age and sex, the overall prevalence rate increased from young age group and reached a peak at 20-29 age group and then the rate decreased gradually. In high endemic areas, however, a peak level of the rate lasted up to 40-49 age group in male. On the other hand, in low endemic areas, the rate was significantly lower in female, though moderate level of the infection was seen in male. The overall prevalence rate was higher in male than in female and the difference was greater in middle age groups. The most significant mode of infection by the inhabitants was the raw eating of sweetfish which commonly harbour metacercariae of M. yokogawai during summer through autumn. Besides, it was noted that the infection can be acquired through contamination with the metacercariae on food of various side-dish and kitchen utensils as well as on hands of a cook when such fish are prepared or handled. The inhabitants usually begin to acquire infection from early June of a year when fishing of sweetfish opens and acquire infection more frequently in July and August when fish are caught more productively and favored for raw consumption by inhabitants. From September, sweetfish are no more favored for raw consumption and accordingly are dried and cooked in this season. The infection in the sweetfish Plecoglossus altivelis as the second intermediate host was first observed from May with low level of infection and the intensity of infection in a fish rapidly increased until reaching a peak in October when sweetfish season normally ends. The first intermediate host snail of M. yokogawai in this area was Semisulcospira coreana (Martens) which is widely distributed in the streams and rivers in this locality.

PURPOSE: The purpose of this study was to evaluate computed tomographic (CT) findings of deep neck space infection(DNSI) with particular attention to the differences in the spaces involved and in complications between odontogenic and nonodontogenic groups. MATERIALS AND METHODS: Forty-four patients(21 odontogenic and 23 nonodontogenic) were included in this study. Among odontogenic DNSls, 15 had the dental infection in the second or third mandibular molar. We compared the CT features between odontogenic and nonodontogenic DNSIs with special emphasis on the differences in the spaces involved and in the rate and type of complications. RESULTS: In all patients, CT clearly differentiated abscess from cellulitis. The most common spaces involved in 21 patients with odontogenic DNSl were the parapharyngeal(n=18), the submandibular(n=18), the anterior visceral(n=13), the masticator(n=9), and the sublingual(n=7) spaces. In contrast, in 23 patients with nonodontogenic DNSI, the anterior visceral space(n=14) was most frequently involved. The parapharyngeal, the submandibular, and the masticator spaces were statistically more frequently involved in odontogenic than in nonodontogenic DNSI(p<.05). Twenty-two patients had one or more complications shown by CT, of which airway compromise was more frequent and severe in odontogenicthan in nonodontogenic DNSI. CONCLUSION: We conclude that the parapharyngeal, the submandibular, and the masticator spaces are more significantly vulnerable in odontogenic DNSl than in nonodontogenic DNSl. The predilection for certain spaces of the neck in odontogenic DNSl seems to originate from the intimate relationship of the mandibular molars to the adjacent deep neck spaces.

PURPOSE: This study was done to develop a death education program for nursing students and evaluate the effects of the program. METHODS: The education program was developed based on ADDIE model. The death education program was developed on the base of educational needs, a comprehensive review of the literature and focus group interviews and then evaluated with 53 nursing students, 27 in the experimental and 26 in the control group. Measurement was done for the meaning of life using the tool by Choi et al (2005) for attitudes concerning death, the tool Thorson and Powell (1998) revised by Kim (2006) and for attitude to end-of-life patient care, the Attitudes toward Nursing Care of the Dying Scale by Frommelt (1991) translated by Cho and Kim (2005). RESULTS: The program consisted of five sessions: Understanding of death, Family bereavement care, Communication and End-of-life patient care, Professional role, and Ethics and legal issues There was a statistically significant difference between pretest and posttest for the meaning of life in the experimental group compared to the control group. About 82% of students in the experimental group were satisfied with the program. CONCLUSION: The results indicate that this program can be used to educate nursing students.

Hurthle cell tumors are an infrequent neoplasm of the thyroid gland in adults. Hurthle cell tumors represent 4. 5% to 10% of all primary thyroid epithelial neoplasms in the foreign literature. It has been known as Hurthle cell tumor since Ewing was the first to use this term in 1928. Tumor occurring in an infant was described by Symmers(1941) and Morrow(1945). The authors experienced a case of congenital Hurthle cell tumor of the thyroid gland in a 2 months old boy. He was admitted to the pediatric surgical department because of a growing mass in the neck since birth. Ultrasonogram showed a huge lobulated homogenous solid mass with medium level echogenicity in the region of the thyroid gland. Subtotal thyroidectomy of right lobe and total thyroidectomy of left lobe were done. The specimen measures 2x3x1.5 cm and 7x3x3 cm, respectively. It was an encapsulated, yellow gray firm and solid mass. The cut surface was smooth, glistening and homogenous. Microscopicully, the tumor was composed of tightly packed regular follicles lined by polyhedral, cuboidal, large cells with a granular acidophilic cytoplasms. The nuclei are vesicular, usually only a little bit larger than those of normal thyroid cells.

A case of Osteogenic sarcoma arised from orbit 4 years after the radiation therapy for retinoblastoma in a 9 years old girl is presented. 4 Years ago, under the diagnosis of retinoblastoma, the left orbital exenteration was performed and was treated with x-ray radiation giving 4.500 gamma tumor dose in 4, weeks. On admission, the left orbital cavity was filled with hard mass and orbital bone revealed extensive destruction with osteoplastic changes on x-ray, and diffuse sarcomatous growth of anaplastic cells with abundant osteogenesis and osteoclastic activity microscopically. It is of authors' opinion that osteogenic sarcoma of orbital bone in this presented case might developed by irradition on retinoblastoma.

PURPOSE: This study was aimed to identify the effect of self-foot reflexology on the relief of premenstrual syndrome and dysmenorrhea in high school girls. METHOD: Study subjects was 236 women residing in the community, teachers and nurses who were older than 45 were recruited. Data was collected with self administered questionnaires from July 1st to August 31st, 2003 and analysed using SPSS/WIN 10.0 with Xtest, t-test, and stepwise multiple logistic regression at a significant level of =.05. RESULT: The breast cancer screening rate was 57.2%, and repeat screening rate was 15.3%. With the multiple logistic regression analysis, factors associated with mammography screening were age and perceived barriers of action, and factors related to the repeat mammography screening were education level and other cancer screening experience. CONCLUSION: Based on the results, we recommend the development of an intervention program to decrease the perceived barrier of action, to regard mammography as an essential test in regular check-up, and to giveactive advertisement and education to the public to improve the rates of breast cancer screening and repeat screening.
