We reviewed retrospectively the medical records of 600 elderly patients, over 65 years old who visited oral medicine. The ratio of the age group was composed of 65${\sim}$74 years old group was 63.7%, 75${\sim}$84 years old group was 32.2%, over 85years old group was 4.2%, and the patients were mostly females. The main chief complaint was composed of oral soft tissue problem(44.1%) and oromaxillofacial pain(39.0%). The majority of systemic diseases was composed of diseases of the circulatory system(30.1%), diseases of the musculoskeletal system and connective tissue(16.8%), endocrine, nutritional and metabolic diseases, and diseases of the digestive system(10.1%). The numerous pateints were diagnosed as soft tissue disease(32.0%), arthrogenous disease(24.1%), and myogenous disease(18.1%) of temporomandibular disease.Principally medication(43.9%), physical therapy(24.2%) were performed. 14.2% of all patients visited oral medicine with a letter of request written by other medical departments or local dental clinics, or referred from other departments in Chosun university dental hospital. These findings indicate epidemiologic characteristics on the elderly patients visited oral medicine. We hope that this study will play a basis in the future research about the elderly patients.

In this study, we compared the gene expression profiles of non-syndromic hyperplastic dental follicle (HDF) fibroblasts and normal dental follicle (NDF) fibroblasts using cDNA micro-arrays, quantitative PCR, and immunohistochemical staining. Microarray analysis showed that several collagens genes were upregulated in the HDF's, including collagen types I, IV, VIII, and XI and TIMP-1, -3, and -4 (fold ratio > 2.0). In contrast, the expression of MMP-1, -3, -10, and -16 together with IL-8 was more than two fold downregulated. The differential expression of the genes encoding alkaline phosphatase, MMP-1, -3, -8, and IL-8 was confirmed by quantitative RT-PCR, while that of 24 HDFs and 18 NDFs was confirmed by immunohistochemical analysis. However, HDFs showed stronger expression of MMP-3 than NDFs (P < 0.001). Collectively, these results indicate that defective regulation of MMPs mediating connective tissue remodeling may be responsible for abnormal tooth eruption.

Sj$\ddot{o}$gren's syndrome(SS) is a chronic inflammatory disorder characterized by lymphocytic infiltration of lacrimal and sailvary glands, which results in dry eyes and dry mouth. SS may exist as a primary condition or as a secondary condition in association with connective tissue disease such as rheumatoid arthritis, systemic lupus erythematosus, or progressive systemic sclerosis. We experienced a patient with primary SS who developed multiple bullae, nodular type of pulmonary amyloidosis and lymphocytic interstitial peumonitis. We believe this to be the first reported case of SS acompanied by these three types pulmonary manifestations at the same time.

This study was conducted to follow the patient referral system operated from the primary health care facilities to the hospital in a rural area of Korea. The subject for this study was sampled from a community health development project carried out by the Korea University in Yeoju Kun, Kyonggi Province. The data of referred patients from primary health care facilities were collected during the period from January 1989 to December 1989. The data was sorted out by a computer system using Database package. The results of this study were summarized as follows: 1. Characteristics of the referred patients were: males $32.0\%$. and females $68.0\%$. The more elderly of the patients visited to the hospital after having been referred there by CHPs or public physicians, $25.9\%$ has been to hospital on at least one previous occasion as against $74.1\%$ for whom it was there first visit. 2. The majority of patients who were referred to a hospital where: medicine $44.3\%$ and orthopedics$16.4\%$, major diseases were : diseases of digestive system $(21.3\%)$ ; symptoms and ill defined conditions $(17.3\%)$ ; diseases of the muscular skeletal system and connective tissue$(14.2\%)$. chronic illness was $82.0\%$ and acute illlness was $18.0\%$. 3. From Community health practitioners more patients referred than the public physicians. Categoris of diseases of the referred patients were different between community health practitioners and public physicians. Due to the. respective differences between the medical restrictions put on the nursing staffs at the community health practitioners and public physicians. From this study it was recommended to define the reason of differences between ~he two groups in futher study. Study as to 1) why one group should be referring more for hospital treatment than the other. And 2) why the two agencies should be referring different diseases.

The gold standard method for diagnosis of tuberculosis is the isolation of Mycobacterium tuberculosis through culture, but there is a probability of cross-contamination in simultaneous cultures of samples causing false-positives. This can result in delayed treatment of the underlying disease and drug side effects. In this paper, we reviewed studies on false-positive cultures of M. tuberculosis. Rate of occurrence, effective factors, and extent of false-positives were analyzed. Ways to identify and reduce the false-positives and management of them are critical for all laboratories. In most cases, false-positive is occurring in cases with only one positive culture but negative direct smear. The three most crucial factors in this regard are inappropriate technician function, contamination of reagents, and aerosol production. Thus, to reduce false-positives, good laboratory practice, as well as use of whole-genome sequencing or genotyping of all positive culture samples with a robust, extra pure method and rapid response, are essential for minimizing the rate of false-positives. Indeed, molecular approaches and epidemiological surveillance can provide a valuable tool besides culture to identify possible false positives.

Purpose: Phosphodiesterase (PDE) inhibitor increases the cellular content of cAMP, and cAMP suppresses connective tissue growth factor (CTGF) expression induced by TGF-${\beta}1$. Therefore, we investigated whether PDE inhibitor suppresses renal fibrosis without suppression of TGF-${\beta}1$. Materials and Methods : Renal interstitial fibrosis was produced by ligation of left ureter in Sprague-Dawley rats. Cilostazol, a selective PDE3 inhibitor, and dipyridamole, a hybrid PDE5, PDE6, and PDE8 inhibitor, were provided in drinking water for 7 days. In addition to the Masson-trichrome score of renal tissue, the concentration of fibronectin and TGF-${\beta}1$ in renal tissue- conditioned media was measured by ELISA. Results : Masson- trichrome score and fibronectin concentration were significantly lower in cilostazol-treated group compared to the control group (P<0.05). Though dipyridamole treatment seemed to suppress the Masson- trichrome score and fibronectin concentration too, the decrements were not statistically significant. There was no difference in TGF-${\beta}1$ concentration among the groups. Conclusion: A selective PDE3 inhibitor cilostazol suppresses renal fibrosis without alteration of TGF-${\beta}1$ expression.

BOOP(Bronchiolitis Obliterans Organizing Pneumonia) is an inflammatory reaction that follows damage to the bronchiolar epithelium of the small conducting airways. BOOP is characterized by the pathologic finding of excessive proliferation of granulation tissue within the respiratory bronchioles, alveolar duct and spaces, accompanied by organizing pneumonia in the more distal parenchyma BOOP may result from diverse causes such as toxic fumes, connective tissue disorders, infections, organ transplantation and drugs or appear idiopathically. Drug induced BOOP has been described in association with acebutolol, amiodarone, cephalosporin, bleomycine, tryptophan, gold salts, barbiturates, sulfasalazine, and carbamazepine. Carbamazepine is an iminostilbene derivative that is used as both an anticonvulsant and pain reliever for pains associated with trigeminal neuralgia. It is structually related to the tricyclic antidepressants. To our knowledge, there have been no previously reported case that has described development of BOOP during carbamazepine treatment in Korea, and only two cases have been reported in the world. We report a case carbamazepine-induced BOOP with a brief review of literature.

Purpose: The purpose of this study was to examine the trends of disease of residents who had treatment in primary health care posts in N-county over the past seven years (1997-2003). The data will assist in planning responses to changes in the health care environment and in planning health promotion programs. Method: A retrospective descriptive survey was conducted of the computerized records of primary health care done by community health practitioners over the last seven years. Cross analysis was conducted among the data using SAS, and the results were displayed in frequencies and percentages. The data were collected from May to September 2004. Results: The results of the study are as follows: 1. The six most frequent diseases were ranked as follows: diseases of the 1) respiratory system, 2) musculoskeletal system and connective tissue, 3) digestive system, 4) skin and subcutaneous tissue, 5) circulatory system, and 6) symptoms, signs and abnormal clinical and laboratory findings. Especially in 2002, circulatory system related disease rose two steps in the ranking and digestive system related disease went a step down. 2. The patients' use of primary health care posts over the past seven years continued to increase on the whole. Conclusions: According to these results, each primary health care post should carry out special health promotion programs that fit the local society of N- county and are in accordance with changes in health care needs.

Hunter syndrome or mucopolysaccharidosis type II (MPS-II) (OMIM 309900) is a rare lysosomal storage disorder caused by deficiency in the activity of the enzyme iduronate-2-sulfatase. This enzyme is responsible for the catabolism of the following two different glycosaminoglycans (GAGs): dermatan sulfate and heparan sulfate. The lysosomal accumulation of these GAG molecules results in cell, tissue, and organ dysfunction. Patients can be broadly classified as having one of the following two forms of MPS II: a severe form and an attenuated form. In the severe form of the disease, signs and symptoms (including neurological impairment) develop in early childhood, whereas in the attenuated form, signs and symptoms develop in adolescence or early adulthood, and patients do not experience significant cognitive impairment. The involvement of the skeletal-muscle system is because of essential accumulated GAGs in joints and connective tissue. MPS II has many clinical features and includes two recognized clinical entities (mild and severe) that represent two ends of a wide spectrum of clinical severities. However, enzyme replacement therapy is likely to have only a limited impact on bone and joint disease based on the results of MPS II studies. The aim of this study was to review the involvement of joints in MPS II.

Follicular bronchitis/bronchiolitis is pathologically characterized by peribronchiolar lymphoid follicles, which is one of reactive pulmonary lymphoid disorders. It is associated with 1) the result of infections such as mycoplasma, chlamydia etc., 2) immunodeficiency syndromes, 3) connective tissue diseases such as rheumatoid arthritis and Sjogren's syndrome and 4) local or systemic hypersensitivity reaction. And it can be also developed without obvious causes and associated diseases(idiopathic). Radiologically it represents as bilateral interstitial patterns of pulmonary infiltrates. In this case, a 49 year-old woman was presented with intermittent cough and sputum. On chest X-ray and CT, $5\times4$ cm sized mass in right upper lobe and paratracheal lymphadenopathies were detected, by which lung malignancy was suspected. Bronchoscopy, trans bronchial lung biopsy and transthoracic needle aspiration showed non-specific findings only. After right upper lobectomy, we could confirm a case of follicular bronchiolitis which presented as an unusual mass-like radiologic finding.
