OBJECTIVES: This study aimed to examine the point prevalence of anxiety, depression and the associated risk factors in hospitalized patients with cancer. METHODS: A total of 114 patients with cancer who admitted to the Cancer Center in St. Mary's Hospital were enrolled for a day. The patients were asked to complete Hospital Anxiety and Depression Scale(HADS). Sociodemographic and cancer related clinical variables were also evaluated. RESULTS: The point prevalence of anxiety and depression was 10.5% and 34.2%, respectively, as assessed with HADS. Logistic regression models revealed that distant metastasis was significantly associated with anxiety in patients with cancer and previous chemotherapy and Low socioeconomic status were significantly associated with depression. CONCLUSIONS: Our results indicate that more than one third of patients with cancer suffer from either anxiety or depression. In addition, previous chemotherapy as well as low socioeconomic status and distant metastasis were associated risk factors of anxiety and depression, respectively. These findings suggest the need for screening and systematized psychosocial intervention for psychological distress in hospitalized patients with cancer.

PURPOSE: Results of 181 percutaneous needle aspiration biopsies performed with an 18-gauge needle during a period of 3 years were analyzed to determine efficacy and safety of the procedure. MATERIALS AND METHODS: Biposies were performed in patients that could not be diagnosed by bronchoscopy or sputum cytology. The biopsy procedure with 18-gauge Crown needle was guided by fiuoroscopy. The biopsy specimen placed in 10% formalin solution were histologically confirmed. RESULTS: In 160 patients(89%), the positive diagnosis was made by percutaneous needle aspiration biopsy. There were 153 lung lesions(120 malignant and 33 benign lesions) and 7 mediastinal lesions. the diagnostic accuracy of malignant and benign disease was 91% and 80% respectively. Complications included pneumothorax(n=11) and hemothorax(n=l):six of them required treatment with chest tube and the remainder showed spontaneous resporption. CONCLUSION: PCNB with an 18-gauge needle provided a reliable, relatively safe diagnostic tool to establish the diagnosis of both malignant and benign chest lesions.

STATEMENT OF PROBLEM: The cement-type abutment would be needed for the reduction of its body in order to correct the axis and to assure occlusal clearance. In the case of intraoral preparation, there is a potential risk that generated heat could be transmitted into the bone-implant interface, where it can cause deterioration of tissues around the implant and failed osseointegration. PURPOSE: The purpose of this study was to assess the difference of the heat transmitting effect on external and internal connection implant types under various conditions. MATERIAL AND METHOD: For evaluating the effects of alternating temperature, the thermocoupling wires were attached on 3 areas of the implant fixture surface corresponding to the cervical, middle, and apex. The abutments were removed 1mm in depth horizontally with diamond burs and were polished for 30 seconds at low speed with silicone points using pressure as applied in routine clinical practice. Obtained data were analyzed using Mann-Whitney rank-sum test and Wilcoxon / Kruskal-Wallis Tests. PESULT: Increased temperature on bone-implant interface was evident without air-water spray coolant both at high speed reduction and low speed polishing (p<.05). But, the difference between connection types was not shown. CONCLUSION: The reduction procedure of abutment without using proper coolant leads to serious damage of oral tissues around the implant irrespective of external and internal connection type.

Implant overdentures are widely used as a treatment method to restore oral function in completely edentulous or partially edentulous patients with severe bone resorption. Using a milled bar, it is mechanically advantageous as the implant fixtures are splinted. Applying additional attachments to the bar has the advantage of dispersing the stress applied to the implant. In this case, a patient who used implant overdentures using 4 implants wanted to fabricate a new prosthesis due to repeated fractures of the denture and weakened retention. Milled bar with ADDTOC attachment and zirconia prosthesis were fabricated by CAD-CAM method and mechanically and aesthetically satisfactory results were obtained.

PURPOSE: To evaluate the diagnostic value of magnetic resonance(MR) imaging in the differentiation of benign and malignant soft tissue masses. MATERIALS AND METHODS: MR examination of 47 patients with pathologically proven soft tissue masses were reviewed. This series included 19 malignant and 28 benign masses of upper and lower extremities, body, and neck. Lesions were evaluated for their margin, signal intensity and homogeneity, pattern and degree of enhancement, involvement of the adjacent tissue, and degree of surrounding edema. RESULTS: Sixteen of benign lesions(57.1%) had well-defined and smooth margin. The tumor margin was irregular in nine lesions(47.4%), however, smooth margin was noted in five cases(26.3%) of malignant lesions. On T2-weighted images, signal inhomogeneity was noted in 84% of malignant lesions and 32% of benign lesions. On Gd-DTPA enhancement study, all malignant lesions(n=18) showed enhancement and 89% showed heterogeneously enhancing pattern. Neurovascular involvement was observed more often in malignancy(n=7) compared to benign lesion(n=1). Direct invasion of the adjacent bone was noted only in malignant lesions(n=3). Surrounding edema was revealed in two benign and 11 malignant lesions. CONCLUSION: MR imaging appears useful for differentiating malignant and benign lesions by identifying tumor margin, signal homogeneity of tumor, pattern and degree of enhancement, involvement of adjacent tissue, and surrounding edema. The nature of the lesion can be determined in the majority of cases although no unique criterion to differentiate benignancy and malignancy is identified.

Endobronchial metastasis from extrapulmonary carcinoma, both clinically and radiologically similar in appearance to a primary lung cancer, is rare. We present a case of endobronchial metastasis from parosteal osteosarcoma. The first abnormality noted on the chest radiography was tramline calcification with branching pattern along the right upper lobe bronchus and intermediate bronchus. This lesion progressed into a solid calcified nodule which increased in size. Another lesion with same pattern was also observed in the left lower lung zone.

PURPOSE: This study aimed at analyzing the causes of death of prisoners of war (POWs) during the Korean War (1950-1953) who fought for the Communist side (North Korea and the People's Republic of China). In 1998, the United States Department of Defense released new information about the prisoners including, 7,614 deaths of the POW during the Korean War. The data on the causes of death of the POWs during the Korean War provides valuable information on the both the public health and history of the conflict. MATERIALS AND METHODS: To analyze the causes of death of the POWs, we classified the clinical diagnosis and findings on 7,614 deaths into 22 chapters, as outlined in the International Statistical Classification of Diseases and Related Health Problems-10th Revision (ICD-10). Second, we traced changes in the monthly death totals of POWs as well as deaths caused by common infectious diseases and external causes of death including injury over time from August 1950 to September 1953. RESULTS: The most common category of causes of deaths of POWs was infectious disease, 5,013 (65.8%) out of 7,614 deaths, followed by external causes including injury, 817 (10.7%). Overall, tuberculosis and dysentery/diarrhea were the most common causes of death. Deaths caused by acute and chronic infection, or external causes showed different patterns of increases and decline over time during the Korean War. CONCLUSION: The information and data on POWs' deaths during the Korean War reflects the critical impact of the POWs' living conditions and the effect of public health measures implemented in POW camps during the war.

One of the treatment options for edentulous state patients with residual ridge resorption is implant overdenture using milled bar and attachment. It not only provides improved retention and stability but can also reduce the coverage of palatal surface. In addition, when a small number of implants are used, milled bar has the effect of being splinted between implant fixtures, which makes it mechanically advantageous under functions such as mastication. The patient in this case was a maxillary edentulous state patient with a considerable amount of residual alveolar bone resorption after removing the existing failed implants. Three implants were planted on both sides and an implant overdenture was fabricated using milled bar and ADD-TOC attachment.

Excessive crown height space increases can cause crestal bone loss and screw loosening after prosthesis is placed. Milled bar and implant overdenture can be used as a treatment method for partially edentulous patients who have severe alveolar bone loss and excessive crown height space. Milled bar can provide primary splinting effect and stability between implants. Also, milled bar with additional retention device such as Advanced Dental Device-Treatment Of Choice (ADD-TOC) and magnet can provide additional retention force for implant overdenture. In this case, the patient has a partially edentulous mandible that has severe alveolar bone loss and multiple number of teeth loss after excision due to leiomyosarcoma. Because of the long-term loss of mandibular molars, the opposing teeth were extruded. Maxillary left molars were corrected to the occlusal plane through molar intrusion, and mandibular left molar region were treated with implant overdenture, using milled bar with ADD-TOC and magnet after implant placement. The clinical result was satisfactory on the aspect of esthetic and masticatory function.
