Salivary duct carcinoma is rare high grade adenocarcinoma, arising from larger excretory duct in major salivary gland, resembling the ductal carcinoma of the breast histologically. We report a case of salivary duct carcinoma of left parotid gland in which fine needle aspiration cytology was performed. Cytologic examination revealed 1) moderate cellularity, 2) flat sheets or three dimensional, tightly cohesive clusters on the necrotic background, 3) sometimes cribriform or papillary configuration, 4) polygonal or cuboidal cells with moderate anisonucleosis with abundant, granular and eosinophilic cytoplasm, 5) round to oval nuclei with irregular chromatin clumps, and 6) 1 or 2 inconspicuous nucleoli. Histologically, the tumor is mainly composed of cribriform intraductal component with central comedonecrosis, and small foci of infiltrating component including well differentiated ductal structures or irregular sheets in a desmoplastic stroma.

Objectives: To determine the prevalence and oral characteristics of cancer patients treated with bisphosphonates in the oncology and maxillofacial prosthesis departments of the General Hospital of Mexico between 2011 and 2013. Materials and Methods: This cross-sectional study included patients who received prior treatment with bisphosphonates; an intraoral examination was performed by 2 standardized examiners. Results: The prevalence of bisphosphonate-related necrosis in 75 patients was 2.6%; the most common malignancy was breast cancer (84.0%), followed by prostate cancer (16.0%). Exostosis was present in 9.3% of patients and the mean Decayed, Missing, Filled Teeth index was 4.64; 44.0% of the study group had a Community Periodontal Index value between 2 and 2.9 (mean, 0.60). Conclusion: A detailed intraoral assessment must be performed before initiating treatment with bisphosphonates to identify risk factors for osteonecrosis.

The ecological characteristics of Dolbae trees, a valuable genetic resource for native pyrus fruit trees, were investigated at four naturally inhabited areas on Mount Kaya, Gyeongsangnam-Do. Most Dolbae trees were found on the southwest side of an old hiking path to a mountain valley at altitudes of 610∼670 m. The surrounding flora consisted of 46 families, 69 genera, 75 species, and 10 varieties. The natural habitat of the Dolbae trees was basically a deciduous broad-leaved forest with a predominance of Quercus serrata and ligneous plants(xylophytes) from the Fagaceae and Betulaceae families. The habitat was also found to be in a second transition resulting from forest disturbance and exhibited a degree of diversity of 2.901-5.065, based on Shannon-Weiner's index. Examination of the Dolbae trees found in Mount Kaya revealed diameter breast heights(DBHs) ranging from 10 to 60 cm, including six old and large Dolbae trees with a DBH of 50∼60 cm, which will be particularly valuable as a genetic resource. Accordingly, the current results suggest that the study areas are a secondary forest in a typical mid-temperate zone resulting from forest damage about 10 years earlier.

Dangui is a formal dress of the wives of high officers and royalty in Chosun Dynasty and it was worn as a day dress in palace and a semi-ceremonial dress in upper-class households. Among the remains of Dangui a double-layered Dangui was found in which two sets of Dangui were combined to be worn as a single piece. The double-layered Dangui consists of an Over-Dangui and an Under-Dangui. The results of the examination of the remains for the Over-Dangui are as follows. As lone as the colors of the remains are identifiable, all of the Over-Dangui were green, whereas the Under-Dangui and lining materials were red. The textile was mostly in woven silk with pattern and it was frequently decorated with golden wefts or foils. A breast embroidery with phoenix and a dragon embroidery were also found. Such Dangui was worn mostly by the high members of the king's palace including the queen, crown princess, bastard princess, and monarch. There were two exceptions of wearing Dangui outside the king's palace. A simple Under-Dangui was made to enable a comfort fit of the two sets of Dangui and the suture was partially sewn. With three doth strings and cuffs, two pieces of Dangui were eventually assembled into one piece of clothing. Differences between the remains and the documents were also found in regards to textile and wearers of Dangui.

연구 목적: 1980년대 이후 미국 여성들의 유방암 조기 진단을 위한 방사선 검진율은 급속히 증가하였음에도 불구하고 유색 인종의 여성들은 여전히 조기 검진의 혜택을 받지 못하고 있다. 유색인종 여성들의 낮은 검진율을 설명하기 위해 여러 건강행위이론을 이용한 관련 요인들이 연구되어 왔다. 이 논문은 미국 보건 의료관련 연구에서 가장 많이 쓰이는 다섯 건강행위 이론을 유색 인종 여성, 특히 한국 이민 여성들의 유방암 조기검진 이행에 적용하기 위해 사회문화적 적합성을 평가하기 위해 고안되었다. 연구 방법: 네 종류의 데이터 베이스(CINAHL, MEDLINE, PsycINFO, Sociological Abstracts)를 이용한 심층적 문헌 고찰을 통해 각각의 이론으로 유방암 조기 검진을 설명한 연구들을 모두 분석하였다. 연구 결과: 각 이론들의 배경, 주요 요인, 그리고 유색인종의 유방암 조기 검진에서의 적용 연구 등을 분석하였다. 결론: 서양 문화권 속에서 개발된 각 이론들이 한국적 정서와 행동을 설명하는데 명확한 한계가 있으며 이러한 한계를 극복하기 위해서는 기존의 이론들을 면밀하게 재분석하여 한국적 특성을 담아낼 수 있는 새로운 이론의 도출이 요구된다.

Interventional radiology is performed under real-time fluoroscopy, and patients are exposed to a wide range of exposures for a long period of time depending on the examination and procedure. However, studies on radiation protection for patients during an intervention are insufficient. This study aims to evaluate the doses exposed during the intervention and the applicability of 3D printing materials. The organ dose for each intervention site was evaluated using a monte carlo simulatio. Also, the dose reduction effect of the critical organs was calculated when using a shielding device using 3D printing materials. As a result, the organ dose distribution for each intervention site showed a lower dose distribution for organs located far from the x-ray tube. It was analyzed that the influence of scattered rays was higher in the superficial organs of the back of the human body where x-rays were incident. The dose reduction effect on the critical organ using the 3D printing shield showed the highest testis among the gonads, and in the case of other organs, the dose reduction effect gradually decreased in the order of the eye, thyroid, breast, and ovary. Accordingly, it is judged that the 3D printed shield will be sufficiently usable as a shielding device for the radiation protection of critical organs.

Inflammatory myofibrolastic tumor (IMT) is a rare borderline neoplasm. It frequently occurs in the lung but occasionally occurs in extrapulmonary sites such as the genitourinary tract, gastrointestinal tract, breast, salivary glands, sinonasal tract, orbit, and the central nervous system. Laryngeal involvement of IMT is very rare. A 61-year-old woman who complained of hoarseness persisting for 3 months visited our hospital. Laryngoscopy showed an elevated lesion in the right true vocal cord. Incisional biopsy was confirmed as larygeal inflammatory myofibrolastic tumor. We performed a transoral excision with CO₂ LASER under suspension examination. Regional recurrence or distant metastasis was not observed after 9 months of follow-up. Herein we report a case of larygeal inflammatory myofibrolastic tumor that was treated with surgery alone, with a literature review.

Purpose: This study was to assess the intention of undergoing Pap testing and to identify influencing factors of HPV knowledge and their attitude related to Pap test by sexual activity among unmarried nurses. Methods: A cross sectional survey design was employed, utilizing a self-administered questionnaire amongst 343 unmarried nurses. Descriptive statistics was utilized to analyze data and inferential statistics used an independent-t test and ${\chi}^2$ test for the differences in measurement variables, and odds ratios for factors on intention of Pap testing by sexual activity. Results: Nurses not sexually active were significantly higher in intention of Pap testing (${\chi}^2$=40.15, p<.001) and influencing factors of HPV knowledge (t=3.93, p=.048) than did nurses who were sexually active. Factors influencing intention were regularity of the breast self-examination (Adjusted Odds Ratio [AOR]=4.20, 95% Confidence Interval [CI]=1.93~9.17), HPV knowledge (AOR=2.49, 95% CI=1.36~4.56), and attitudes toward the Pap test(AOR=2.33, 95% CI=1.25~4.34) amongst nurses who never had sexual experience. Conclusion: It is necessary to minimize negative attitudes of Pap testing and to increase HPV knowledge in order to improve intention of Pap testing for women who were not sexually active. More focus would be given to sexually active women to get Pap tested as a preventive measure for cervical cancer.

Cytologic diagnosis of the metastatic tumors to the thyroid is important in the management of the patients. There have been rare reports analyzing fine-needle aspiration (FNA) cytology of metastatic tumors to the thyroid. This study examines comprehensive cytologic findings of metastatic tumors to the thyroid with radiologic findings. The FNA cytology slides obtained from 12 cases with metastatic tumors of the thyroid; lung cancer (n=5), tongue and tonsil cancer (n=3), esophageal cancer (n=2), and breast cancer (n=2) were reviewed. Radiological study showed single mass with heterogeneous texture or multiple masses without calcification. Metastatic tumor was easily considered in a differential diagnosis of FNA cytology because they had peculiar cytological features which were not seen in primary thyroid tumor. The smear background varied from predominantly necrotic, bloody, and inflammatory to colloid. The aspirates exhibited a mixture of benign follicular cells and malignant cells in 6 cases. The characteristic cytoplasmic features of the tumor cells, such as keratin, mucin and melanin, were found in 9 cases. Although some cases mimic primary thyroid neoplasm, a careful examination of the cytological characteristics may help cytopathologists to recognize a metastatic tumor in the thyroid by FNA, and may help the clinicians to establish a proper treatment plan.

Sentinel lymphnode biopsy is widely performed in the management of malignant melanoma and breast cancer. The sentinel lymphnode is the prime site of draining from the malignant lesion and of metastasis. The aim of this study was to evaluate a usefulness of lymphoscintigraphy in conjunction with a removal of sentinel lymphnodes of skin and soft tissue malignancy. We studied 11 patients selected between January, 2003 and November, 2004. Clinically sentinel lymphnodes free of metastasis were examined with lymphoscintigraphy, gamma detection probe and vital dye staining, and we reviewed histopathologic findings and inert status of the nodes and the results fo treatment. Nine cases were malignant melanoma, one was squamous cell carcinoma on the left hand and another one leiomyosarcoma. Sentinel lymphnodes were identified in all cases. Three cases of malignant melanoma had positive sentinel lymphnodes on histological examination. All patients with positive sentinel lymphnodes were treated with therapeutic regional lymphadectomy, chemotherapy and adjuvant regimen. Four patients underwent PET scanning and followed sentinel lymphnode biopsy. Two had no metastasis signs on PET scanning. Therapeutic lymphnode dissection was carried out upon the patients whose sentinel lymphnode was positive on PET scanning. We contend that lymphoscintigraphy and sentinel lymphnode biopsy are reliable to confirm regional lymphnode metastasis of the skin and soft tissue malignancy, and blind extensive lymphnode dissection can be spared.
