PURPOSE: The purpose of this predictive study was to identify factors affecting health related quality of life (HRQoL) in patients with rheumatoid arthritis (RA). METHODS: The participants in this study were 131 patients with RA who were recruited from the outpatient clinic of a university hospital in Seoul. Disease activity in rheumatoid arthritis was evaluated by calculating the Disease Activity Score 28. Disability in activities of daily living (ADL) was assessed with the Korean Health Assessment Questionnaire, and depression with The Center for Epidemiologic Studies Depression Scale. HRQoL was evaluated using The Short Form 36 Health Survey. Data were analyzed using descriptive statistics, correlation, and hierarchical multiple regression. RESULTS: Pain, disability in ADL, disease activity, and depression correlated negatively with physical and mental dimensions of HRQoL. But hierachical multiple regression analysis revealed that disability in ADL and depression were the only variables negatively influencing physical and mental QoL after adjustment for influences of sociodemographic variables. CONCLUSION: Results of this study suggest that disability in ADL and depression, rather than disease activity and pain have profound effects on HRQoL in patients with RA. Further studies are needed to assess the predictive ability of disease activity and pain on HRQoL in this population.

This study was performed to investigate the survival rate of single implant used in maxillary anterior region during follow up periods. 231 patients whose single missing tooth in maxillary region had been replaced with 237 implant at the periodontal dept. of Yonsei University Hospital between February 1993 and December 2004. The following results are compiled from 231 patients who received single implant surgery. 1. The major cause of single tooth loss in maxillary anterior region is trauma, followed by periodontal disease and congenital missing. 2. The total survival rate of single implant placed in maxillary anterior region is 94.5%. 3. The survival rate of single implant placed in type II and type IV was 100% and in type lll was 92.7%. As for the bone quantity, the survival rate in type A(100%) was most, followed by type B(97.3%) and type C, D (93.5%). 4. The survival rate of implant placement combined with advanced surgery was 94.4%. The results showed that the placement of single implant is considered as a reliable treatment option for a single missing tooth in maxillary anterior region except in certain extreme conditions especially with poor bone quality and quantity.

Neurofibromatosis also referred to as von Recklinghausen`s disease, is an autosomal dominant disease, which is characterized by cutaneous neurofibromas, cafe-au-lait spot, and axillary freckles. Although neruofibromatosis is a congenital disorder, the pulmonary manifestation become evident in adulthood. Approximately 15percent of patients with cutaneous lesions have intrathoracic neurofibromas. In some patients with neurofibromatosis, the lungs are the seat of interstitial fibrosis, leiomyoma, and bullous lesion, meningocele or less commonly lung cancer. The association of neurofibromatosis and lung cancer is rare, A 47-year-old man, who was a heavy smoker, was admitted to our hospital because of hemoptysis. Since cafe-au-lait sopts, diffuse pigmentation and multiple neurofibromatosis were observed on the skin, he was considered to have von Recklinghausen`s disease. Chest X-ray film showd extensive hazy density affecting all of his lung field, and minimal peribronchial infiltratin in his left lower lung field. Chest CT showed that near total consolidative lesions were present of right middle lobe. Also, some patchy infiltration were present in his right lower lobe and some of left lower lobe. Histoathological examination of the percutaneous lung biopsy specimen demonstrated that he had undifferentiated large cell carcinoma. The Authors have experienced a case of neurofibromatosis combined with undifferntiated large cell carcinoma. A brief review of related literature was conducted.
