Exaggerated acute and late toxicities following radiotherapy have been reported in patients with pre-existing connective tissue diseases, such as systemic lupus and scleroderma. Behcet's disease (BD) is a relapsing multisystem connective tissue disease characterized by vasculitis in the mucocutaneous, ocular, gastrointestinal, respiratory, neurologic, urogenital, articular, and cardiovascular systems. Data concerning the relationship between radiotherapy toxicity and BD are limited in the literature. Here, we report a case of lung cancer treated with radiotherapy (60 Gy) in a patient with BD. No severe radiation-induced toxicity was observed. Radiation-induced toxicity in patients with BD has also been discussed.

Chondrosarcoma is a rare entity of malignant tumor which arises from cartilaginous tissue, and the literatures on this disease are scarce. The first-line of treatment for cardiac chondrosarcoma is surgery. Due to early local recurrence and distant metastasis, the prognosis is poor even after complete surgical excision. We present a case of chondrosarcoma in the left atrium causing functional mitral stenosis which required urgent surgical intervention, and the successful treatment outcome.

Hamartoma had been considered as a congenital malformation of a tumerous lesion since the original description by Albrecht in 1904. Pulmonary hamartoma is able to classified as endobronchial and intrapulmonary hamartoma clinically, and is considered to benign mesenchymal neoplasms which originated in peribronchial connective tissue, and so called mesenchymoma by someone. We have experienced 3 cases intrapulmonary hamartoma which were discovered during routine chest film check up at all cases and are able to detailed histologic examination by electron microscopy at one case.

Superficial angiomyxoma (SA) is a rare, benign, cutaneous soft tissue tumor. It is composed of myxoid matrix and blood vessels. Herein, we report a case of a solitary SA on the posterior neck of a 6-year-old boy. An analysis of the biopsied specimen showed a prominent myxoid stroma with thin-walled, branching blood vessels, revealing the presence of an SA. SA especially that originating in the posterior neck, is rarely seen and should be considered as a differential diagnosis for a solitary mass in the posterior neck.

Palisading encapsulated neuroma is a rare, benign, cutaneous nerve sheath tumor. It usually occurs as an asymptomatic solitary skin-colored papule and commonly affects the nose and cheeks. Sometimes, it involves other sites, including the shoulder, upper arm, and trunk, but rarely involves the oral mucosa, including that of the lip. In our case, a 63-year-old female patient complained of a pinkish rubbery nodule on her lower lip. Histopathologic examination demonstrated a well-circumscribed nodule encapsulated by connective tissue stroma in the dermis. The nodule consisted of palisading spindle-shaped tumor cells with wavy and basophilic nuclei. The cells were arranged in streaming fascicles with multiple clefts and were strongly positive for S-100 proteins. To our knowledge, only three cases of palisading encapsulated neuroma on the lower lip have been reported in the Korean literature. Herein, we report a rare case of an oral palisaded encapsulated neuroma.

In order to observe the distribution of mast cell on the stages of the mammary carcinogenesis, the numerical changes of mast cells in the mammary tumor development in rats treated with DMBA and compound 48/80 have been investigated by the light microscope. The results observed were summarized as follows: The appearance of tumor were not observed during the whole experimental period in the rats of the control group received injection of sterile saline, but tumors appeared in 100% of the animals, the tumor induction time that represented the number of days elapsing between the 3rd DMBA administration until a first tumor became $10{\times}10mm$ in diameter was $42.5{\pm}4.7$ days and the mean number of tumor masses per rat was $3.4{\pm}1.2$ in the DMBA treated group. And the majority of the DMBA-induced mammary neoplasms were appeared cervical mammary gland and thoracic mammary gland. The histological findings of mammary carcinoma were recognized adenocarcinoma in the DMBA treated group. Mast cells were distributed within the adipose tissues and the interglandular connective tissue in the control, but found to be randomly dispersed within the tumor cell masses, in the connective tissues adjacent to the periphery of the tumor, the adipose tissues and the subcutaneous tissues contiguous to the region of tumor development in the DMBA treated group. Numerical alterations of mast cells were observed in the mammary tumors that separated into three major classes of tumors: hyperplasia, atypical hyperplasia and carcinoma. The number of mast cells were distributed in the connective tissues adjacent to the mammary gland was $45.3{\pm}3.4$ cells in the control group, but was $50.2{\pm}4.9$ cells, $126.7{\pm}10.5$ cells and $340.3{\pm}19.2$ cells according to each stages of mammary tumorigenesis in the DMBA treated group.

Given that the demand for dental care for elderly individuals is expected to increase according to demographic changes, long-term roadmaps for the current health insurance system should be actively planned. The study aimed to investigate the health insurance system in Korea, compared to that of Japan, and suggest directions for the work of dental hygienists to provide basic data on efficient improvements in the health insurance system. Based on the collected data, the website was used to collect additional related data from Korea and Japan. The most common cause of death in Korea was malignant neoplasms, and most patients were hospitalized for diseases and disorders of the musculoskeletal system and connective tissue. Dental care covered by Korean medical insurance for individuals aged 65 years or older was treatment oriented, such as dentures and implants, while in Japan, treatment-intensive items, such as visiting a dental hygienist for guidance and provision of home-care professional oral hygiene treatment, were covered. The percentages of remaining teeth in Korea and the percentage of remaining 20 teeth were 68.9% in those aged 65 to 74 years and 51.2% in those aged 75 to 84 years in Japan. A strategy for promoting oral health among elderly individuals should be established, and a multilateral intervention approach is required to prevent oral problems from leading to deterioration of whole-body health. The role of dental hygienists in providing comprehensive assessment to elderly individuals is important. In order to provide systemic oral care, it is necessary to introduce oral care systems according to the national policy.

The aim of this study is to know about condition of alternative medicine. Methods which An literature search in Pubmed January 2000 to March, 2010 was performed. RCT(Randomized Controlled Trial), CCT(Controled Clinical Trials), and OD(efficacy studies with either a controlled or an Other than controlled Design) were included. PubMed databases were searched using key terms relating to alternative medicine. 19 clinical trials were included among 682 studies searched. RCT was 44%, CCT was 16% and OD was 40% in the review. In the all of included studies, the acupuncture and the massage was the biggest part. The using rate was 20% of pain control about Disease of the Musculoskeletal system and Connective tissue, 15% of Certain infectious and parasitic diseases, and 15% of Neoplasms. There was lack of evidence that alternative medicine was effective for progress. Future well-designed clinical trials is needed.
