BACKGROUND: The growth of elderly population increased the need for oral health care. Elderly patients with poor teeth alignment needs more attention with orthodontic treatment METHODS: Elderly patients visiting department of orthodontics, Kangdong Sacred Heart Hospital between 2000-2004 were treated with fixed appliances in one or both dental arches. Treatment plans were different from than that of younger patients and included uncommon and strategic removals of teeth and prosthesis. RESULTS: There was decrease in orthodontic treatment forces with increasing age, and the observation made from this study was favorable in the patients' as well as in the orthodontist's, point of view. It was possible to move the remaining teeth considerably, and the retention was made with various fixed appliances. CONCLUSIONS: Orthodontic treatment is not limited by patient age. However, it is wise not to extend treatment goals too far beyond the patients' objective needs

Lentigo maligna melanoma(LMM) is the least common type of melanoma. LMM is almost exclusively located on sun-exposed skin of the head and neck. We describe a case of lentigo maligna melanoma evolved from lentigo maligna in 82-year-old man. Five years ago, the patient developed a brownish pigmented lesion on the left cheek. The lesion progressed slowly, and several months ago, a black pigmented patch was developed in the periphery of the brownish pigmented patch. Histopathologic examination of the lesions revealed findings consistent with lentigo maligna and lentigo maligna melanoma.

Microcystic meningioma is a rare variant of meningiomas. This unusual variant was originally described by Masson, who labeled it "humid". The computed tomographic scan or magnetic resonance images of these tumors resemble those of a glial or metastatic tumor with cystic or necrotic changes. There is no definitive method for differentiating cystic meningiomas from these more common tumors. But immunohistochemically, they share a similar pattern of positive staining for epithelial membrane antigen and vimentin with other meningiomas. Our case was a 34-year-old woman with a tumor mass on the right frontal area. She was admitted to hospital because of generalized tonic seizure. Grossly all of the tumor could be removed, and histopathologically this tumor was revealed to be a microcystic meningioma.

8.Effects of nicotine on the formation of osteocalcin and osteoprotegerin and synthesis of its mRNA in MG63 osteoblast-like cell.
Korean Journal of Orthodontics 2004;34(6):514-525
The purpose of this study was to evaluate the correlation between nicotine and the activity of bone forming cell. MG63 osteoblast-like cells were used for this study. Several factors were examined including the proliferation of cell, alkaline phosphatase activity, the formation of osteocalcin and osteoprotegerin, and the synthesis of its mRNA. MG63 osteoblast-like cells were incubated for 1, 2, 3 and 6 days with nicotine added to the culture medium in 1.0 micrometer, 1.0 mM, 2.5 mM, 5.0 mM, 7.5 mM, and 10.0 mM concentrations. The proliferation of MG63 osteoblast-like cells was temporarily activated at the low nicotine concentrations. At high concentrations (>5.0 mM), however, it was suppressed. Alkaline phosphatase activity was suppressed in a dose-dependent manner as the concentration of nicotine increased. Osteocalcin decreased in a dose-dependent manner at high nicotine concentrations of more than 7.5 mM and the same result was show when the osteoblasts were treated with low concentrations for longer than 3 days. There was a difference in the influence of nicotine on the synthesis of osteocalcin mRNA and formation of osteocalcin itself at 1 and 3 days. Generally, osteoprotegrin notably declined in all experimental groups. However, the level of its mRNA inc-reased at high nicotine concentrations of more than 7.5 mM after 3 days and more than 5.0 mM after 6 days.

10.Surgical Treatment of Slipped Capital Femoral Epiphysis.
The Journal of the Korean Orthopaedic Association 1999;34(2):417-424
PURPOSE: The aim of this article is to define the safety and effectiveness of in situ pin fixation in treatment of SCFE (Slipped Capital Femoral Epiphysis). MATERIALS AND METHODS: The author reviewed 14 cases in 13 patients. The mean follow-up period was 38 months. The methods of treatment were divided into two groups. The group A: 4 cases were treated with closed reduction followed by multiple pinning before 1986, and group B: 9 cases were treated with in situ fixation followed by multiple pinning (3 cases) or one central ASNIS screw (6 cases) after 1986. RESULTS: Before 1986, high incidence of complications (Avascular necrosis change followed by severe osteoarthritis) were noted after closed reduction (2/4). In contrast, 9 cases of in situ fixation were well united without further slippage or specific complication such as avascular necrosis or chondrolysis. One case was involved bilaterally and found incidentally during follow up check without any subjective symptom. One case was developed as a manifestation of osteogenesis imperfecta. Failure of removal of the fixated screws (Knowles pin 8 Titanium cannulated screw) were in 3 cases. CONCLUSIONS: Closed reduction may be a very dangerous procedure, increasing the rate of complication in spite of its necessity. We considered that closed reduction should be avoided regardless of the severity of the displacement in chronic case.
