Purpose: The purpose of this study is to evaluate characteristics of a deep infection after arthroscopic knee surgery. Materials and Methods: We selected 894 patients who underwent arthroscopic knee surgery between February 1994 and August 2006. We analyzed the results of the patients with definite infection. Results: Seven cases out of the 894 knee arthroscopic surgery which was performed by one surgeon during 12 years were diagnosed as postoperative deep infection (0.9%). Infection developed in one repair case among the meniscal surgeries (1419=0.2%). There were six infection cases in intraarticular ligament reconstruction (6/343=2%); 3 in ACL surgeries (3/152), 2 in PCL surgeries (2/70) and 1 in combined cruciate ligament surgery and extra-articular reconstruction (l/26). Conclusion: Postoperative infection rate of arthroscopic knee surgery was relatively low. However an attention for the prevention of postoperative deep infection should be paid in intraarticular ligament reconstruction because of its relatively high risk of infection.

Tuberculous arthritis on the sternoclavicular joint is an uncommon disease and a delayed diagnosis can be due to the obscure clinical symptoms. We should suspect tuberculous arthritis in patients with slowly progressive pain, swelling, mild fever and a previous history of tuberculosis. Early diagnosis is important through conducting a thorough physical examination and performing laboratory tests and radiologic study. Tuberculous arthritis on the sternoclavicular joint should be treated with a combination of systemic antituberculous agents and thorough surgical debridement in marked damaged joints. When performing this operation, it is important not only to minimized the injury of the costoclavicular ligament, but also to avoid injury to the surrounding the vital structures such as the mediastinum and pleura after aggressive resection or radical debridement. We describe here 2 cases of the tuberculous arthritis on the sternoclavicular joint: one case had a good result after surgical debridement with using an anti-tuberculous agent, and the other had fatal complications such as mediastinal abscess and pleural effusion after the operation.

Schwannoma is a common peripheral nerve tumor that mainly occur at head and neck, flexor muscle of upper, and lower extrimity. In posterior tibial nerve schwannoma, diagnosis is difficult, since physicians often consider achilles tendinitis, posterior impingement syndrome, retrocalcaneal bursitis, or injury of the flexor tendons, as the primary cause in patients with posterior ankle pain. Ultrasonogram may be a simple tool to differentiate such various diseases. The authors report a case of posterior tibial nerve schwannoma diagnosed with ultrasonogram, which was initially misunderstood as achilles tendinitis.

Objectives: The purpose of this study was to examine the scaling experience and related factors of people diagnosed with rheumatoid arthritis. Methods: The subjects were 30,680 people diagnosed with rheumatoid arthritis from the 2014 community health survey who were $${\geq_-}19$$ years old. Data were analyzed by chi-square test and multiple logistic regression analysis. Results: Those having regular scaling included well educated people, drinkers, more than three times tooth brushing practice, and regular dental checkup. The respondents were in the higher quartile of income And the respondents who were in the higher quartile of income were less likely to have scaling experience (p<0.05). Conclusions: The scaling experience was closely related with the age, educational level, residential area, income, drinking, tooth brushing practice, and regular dental checkup. It is necessary to investigate the influencing factors of rheumatoid arthritis and periodontal diseases in the further studies.

Purpose: To provide baseline data for prevention and education of diabetic foot in Korea. Materials and Methods: 216 diabetic patients are included in this survey. The average age is 58.64 year old with average 9.92 years of diabetes mellitus periods. Among them, 41% used insulin injection, 42% oral medication, 14% both and 3% diet were used for their blood sugar control. The diabetic foot survey was done. Results: The survey of patients symptom and disease of their feet results: 49% had sensory decrease in their feet. Associated disease in foot were callus(15%), heel pain(10%), bunion(4%), toe deformity(2%), Tinea pedis were 9%, tingle sensation were 17%, and swelling on feet were 2%, The survey of patients privious history of foot problems are: 8% had previous operation history on their feet and 17% had history of infection on their feet, 23% had bullae history, The survey of patients prevention and education are: Those who have had more than one diabetic foot education were 45.7%, and among them 24% had routine regular foot check up. Only 5% wear special diabetic shoe and 3% had custom orthotics. Conclusion: Interests to diabetic foot care is increasing in diabetic patients in Korea. However still we need more education, and efforts for prevention. Special education and diabetic shoe is still low, The survey data could be good baseline for diabetic prevention and education.

비만은 고혈압, 제2형 당뇨병, 지방간, 고지혈증, 퇴행성관절염, 일부 암성 질환 등 다양한 만성 퇴행성 질환들을 유발할 수 있으므로 비만을 하나의 질환으로 인식하고 치료할 필요가 있다. 비만은 식사요법, 운동요법과 행동수정요법을 병행해야 최상의 치료효과를 거둘 수 있다고 알려져 왔지만, 비만 치료가 끝나고 4년 후에 빠진 체중의 절반만이라도 다시 늘지 않고 유지하고 있는 사람은 10-30%에 불과하다. 그러나 비만 문제가 중요하고 현재까지의 치료방법이 성공적이지 못함에도 불구하고 비만의 약물 치료의 적절성에 대해서는 논란이 있다. 그러나 최근 비만의 약물 치료에 대해 재평가가 이루어지고 있으며, 식사, 운동, 행동요법과 약물치료의 병합 요법이 효과가 있음을 입증하는 연구결과들이 보고되고 있다. 여기에서는 비만증의 진단기준과 치료원칙을 간단히 설명하고 비만증의 약물요법을 위주로 살펴보도록 하겠다.

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.

On MRI, abnormal signals of the intervertebral disc, destruction of the upper and lower vertebral body endplate around the disc, and bone marrow edema around the endplate are considered typical findings of infectious spondylitis. These findings can also appear in various non-infectious spinal diseases, such as degenerative changes, acute Schmorl's node, spondyloarthropathy, synovitis, acne, pustulosis, hyperostosis, and osteitis (SAPHO), chronic recurrent multifocal osteomyelitis, and calcium pyrophosphate dihydrate crystal deposition disease. The imaging findings of infectious spondylitis that can be differentiated from these non-infectious spinal diseases on MRI are high signal intensity and abscess of the disc space, an abscess in the paraspinal soft tissue, and the loss of the linear low signal intensity on T1-weighted images of the bony endplate. However, these differentiation points do not always apply since there are many similarities in the imaging findings of infectious and non-infectious diseases. Therefore, for an accurate diagnosis, it is important to know the imaging characteristics related to the pathophysiology of not only infectious spondylitis but also non-infectious spinal diseases, which requires differentiation from infection.

For some patients with joint illnesses such as rheumarthritis or varus deformity, the total knee arthroplasty (TKA) procedures are performed. However, when inserting metal cutting guide for the procedures, due to the femoral shaft bowing, complications such as the cortex of the femoral shaft damages or secondary fractures can be caused. If the central coordinate value of the femoral shaft is known, the metal cutting guide could be inserted into the anatomical center, so such complications can be prevented. In this study, CT images of femoral shafts of 10 individuals in the experiment group who are in need of receiving the total knee arthroplasty procedures and those of 10 individuals in the control group without illness in the femoral shaft have been utilized to locate the 3-dimensional coordinate values. Then, Matlab was utilized to identify the central coordinate value in order to obtain a graph reflecting the anatomical shapes as well as to acquire the 3-dimensional radial curvature values by section. As a result, the average curvature range and standard deviation of femoral shafts of the experiment group was determined to be $758.15{\pm}206.3mm$ whereas the that of the control group was determined to be $1672.97{\pm}395.6mm$. The statistical significance of the measured results was verified through f-distribution analysis. Based on these results, it was verified that the level of curvature of the femoral shaft of the experiment group was higher. If the anatomical central points are located and analyzed using this methodology, it would be helpful in performing orthopedic operations such as the total knee arthroplasty.
