Osteomyelitis is an infection of bone or bone marrow, caused by pyogenic bacteria or mycobacterium. Osteomyelitis can be acute or chronic, inflammatory process of the bone and its structures. Chronic osteomyelitis will result in variable sclerosis and deformity of the affected bone. With an infection of the bone, the subsequent inflammatory response will elevate this overlying periosteum, leading to a loss of the nourishing vasculature, vascular thrombosis, and bone necrosis, resulting occasionally in formation of sequestra. These become areas that are more resistant to systemic antibiotic therapy due to lack of the normal Havesian canals that are blocked by scar tissue. At this aspect, not only systemic antibiotic therapy, but also surgical debridement maybe required to remove the affected bone and prevent disease propagation to adjacent areas. We experienced a patient who diagnosed tongue cancer and underwent wide partial glossectomy few years before, with an ulcerative lesion around right retromolar trigon. We diagnosed cancer recurrence because PET indicated hot uptake on mandible which was nearby previous tongue tumor site. The patient received hemiglossectomy via paramedian mandibulotomy, partial mandibulectomy and fibula osteocutaneous free flap reconstruction. But final diagnosis was mandible osteomyelitis on pathology report. Here, we present the case with a review of the related literatures.

The relationships between nutrients intake, physical activity and bone mineral density were investigated in 19 elderly men aged 71-80 years. A trained nutritionist interviewed usual dietary intake and daily activity with a questionnaire, and bone mineral density was measured at the lumbar spine and three regions of the proximal femur (femur neck, Ward's triangle and trochanter) with a Luna DP3 dual photon absorptiometry. The correlations between dietary calcium intake and bone mineral density at the lumbar spine and trochanteric region were significant at P<0.05 and P<0.01 level respectively. the significant correlations were also found between vitamin A(P<0.005), riboflavin(P<0.01), and ascorbic acid(P<0.05) intake and bone mineral density at these sites. Higher physical activity was associated with greater bone mineral density of four sites, but this was not significant. But there were significant relationships between total energy expenditure and bone mineral density of the lumbar spine(P<0.01), femur neck (P<0.05) and Ward's triangle(P<0.05). In this study the results revealed that bone mineral density of the lumbar spine and trochanteric region were associated with dietary calcium intake. And bone mineral density of the femur neck and Ward's triangle were related to physical activity but not to nutrients intake. In conclusion, dietary calcium intake seems to be a important factor for greater bone mineral density. Further evidence will be needed that physical activity protects against bone fracture and osteoporosis in the edlerly.

The central giant cell granuloma is a benign tumor seen generally in the mandible, but rarely in other cranial bones. Herein, we present a 51-year-old man with central giant cell granuloma in the right zygomatic bone. Physical and radiologic examinations of the central giant cell granuloma in the zygomatic bone showed that specific and preoperative diagnosis is usually difficult. Therefore, clinicians should consider the possibility that central giant cell granuloma may occur in the zygomatic bone mimicking other more frequently observed lesions.

The bone mineral density(vertebrae Ll-4, femoral neck, Ward's triangle and trochanter) of 160 healthy adult women aged 29-45 was measured and general characteristics, anthropomentric measurements, and dietary intake were also studied to determine the main factors affecting the bone mineral density(BMD) of adult women. The nutrient intake of the subjects was adequate to RDA level except energy, Ca, Fe, and vit A. The BMD of vertebrae L24 showed significant positive association with nutrient intake such as animal protein, P, Ca(animal) and Fe(animal). The BMD of the femoral neck correlated significantly with anthropometric measurements such as height, weight, waist circumference, hip circumference, body fat and body mass index. The BMD of both sites(vertebrae L24 and femoral neck) were significantly related to vertebrae L24 was daily Ca intake and that of femoral neck was daily energy expenditure. In conclusion, adequate nutrient intake, especially protein, P, Ca and Fe as well as increases in physical activity were suggested to prevent the loss of bone mineral density in adult women.

This study was conducted to investigate the distribution of bone density according to age and the prevalence rate of osteoporosis I 613, middle-aged women who visited Saint Bundo Hospital in Pusan from June to December, 1997. Mean bone density of lumbar spine(L2L4), and femoral neck of 50-59 years of age was significantly lower than those of 40-49 years of age(p<0.05). At the 60years of age, mean bone density of two sites were less than those of 50-59 years of age. Mean bone density of lumbar spine tin the group of sixties were 20.7% lower than that of group aged under 40 ; For femoral neck, women in their sixties showed 22.6% lower density compared to the women aged under forty. Bone density of ward's triangle of sixties were the least, which was 34.2% lower than that of group aged under 40. Bone density in lumbar spine, femoral neck, trochanter and ward's triangle correlates strongly with each other(p<0.001). The proportion of osteoporosis was 3.6% in the group of forties, 10.9% in the group of fifties and 33.8% for the group aged over 60, which was assessed by bone density of lumbar spine. Bone density of lumbar spine, femoral neck and ward's triangle were positively correlated with height, weight and BMI(p<0.001∼p<0.01), and weight showed highest correlation with the bone density. Forty-four percent of variation in lumbar spine bone density was explained by age and weight.

An osteoma of the external auditory canal(EAC) is an uncommon benign tumor. If a canal obstruction occurs, ear fullness or conductive hearing loss can arise. But, the association of an osteoma with a cholesteatoma is extremely rare. Therefore, we report a case of a 35-year-old female patient with osteoma of temporal bone that was complicated with EAC cholesteatoma.

Background and Objectives: Adenoid cystic carcinoma (ACC) is a unique tumor characterized by frequent and delayed distant metastasis (DM) with uncommon regional lymph node metastasis. We evaluated the factors affecting DM of ACC and survival after appearance of DM. Materials and Methods: Medical records, radiographs and pathologic slides were reviewed for 94 patients from 1979 through 2001. Results: DM of ACC occurred in 46 patients, and developed more frequently in patients with tumors of the solid histologic subtype than in patients with tubular or cribriform subtypes. DM occurred less frequently in the sinonasal tract, and development of DM was not affected by tumor stage. Disease-specific 5- and 10-year survival rates were 88% and 72% for patients without DM, respectively and 76% and 48% for those with DM(p=0.02). Regarding the site of DM and its impact on outcomes, 30 patients had lung metastasis alone, 5 patients bone metastasis alone and 6 patients developed both lung and bone metastasis. Median survivals after appearance of DM among patients with isolated lung metastases and those with bone metastases with or without lung involvement were 54 and 21 months, respectively (p=0.04). Conclusions: Development of DM in ACC is predicted by solid histologic subtype, and major salivary gland or oral/pharyngeal rather than sinonasal primary site. Those patients with bone involvement with our without lung metastases had worse outcomes than those with pulmonary metastasis only.

STATEMENT OF PROBLEM: Loss of the marginal bone to the first thread have been accepted but continuous effort have been made to reduce this bone loss by varying implant design and surface texture. PURPOSE: This animal study has examined the histomorphometric variations between implants with micro-thread, micro-grooved and turned surfaced neck designs. MATERIAL AND METHODS: Four mongrel dogs have been used the premolars removed and left to heal for three months. One of each implant systems with turned neck, micro-thread and micro-grooved were placed according to the manufacturers’protocol and left submerged for 8 and 12 weeks. These were then harvested for histological examination. RESULTS: The histologically all samples were successfully ossointegrated and active bone remodelling adjacent to implants. With the micro-grooved implants 0.40 mm and 0.26 mm of the marginal bone level changes were observed at 8 and 12 weeks respectively. The micro-threaded implants had changes of 0.79 mm and 0.56 mm at 8 and 12 weeks respectably. The turned neck designed implants had marginal bone level changes of 1.61 mm and 1.63 mm in 8 and 12 weeks specimens. A complex soft tissue arrangement could be observed against micro-threaded and micro-grooved implant surfaces. CONCLUSION: Within the limitations of this study, it could be concluded that implants with micro-grooved had the least and the turned neck designed implants had the most changes in the marginal bone level. The textured implant surfaces affect soft tissue responses.

Nutritional factors affecting bone mineral density (BMD) in the different age groups of Korean women were investigated to obtain baseline data for maintaining bone health. Information on diet and anthropometry were collected in 80 elementary school children (height 127.2 cm, weight 27.3 kg), 84 high school students (height 161.6 cm, weight 52.4 kg), 100 adults aged 25 to 35 years (height 159.4 cm, weight 52.7 kg) and 120 elderly people over 60 years of age (height 150.9 cm, weight 55.6 kg). Data for nutrient intake were obtained by 24-hour recall method. BMDs of lumbar spine (L$_2$-L$_4$) and femoral neck were measured by dual energy x-ray absorptiometry. The relationship between BMD of femoral neck and nutritional factors were analyzed. The average BMD of femoral neck for females was 0.61 g/$\textrm{cm}^2$ in children, 0.88 g/$\textrm{cm}^2$ in adolescents, 0.90 g/$\textrm{cm}^2$ in adults, 0.64 g/$\textrm{cm}^2$ in elderly people. Among the adult subjects, 11.0% was classified as osteopenia in the femoral neck. For the elderly, the prevalence of osteopenia and osteoporosis were 34.2% and 47.5% of the subjects. It was shown the intake of energy, protein, plant protein, animal protein, fat, carbohydrate, Ca, P, Fe, vitamin A, thiamin, riboflavin, niacin, vitamin C, carbohydrate energy percent and fat energy percent influenced bone health status in all age groups. In the MAR on bone health status, children, adult and elderly subjects were significantly different among groups classified by bone health status and the MAR of the groups with good in bone health was higher. The RDA percent of each nutrient was influence factor on BMD. Nutrient intake of energy, protein, P, Fe, thiamin, niacin were lower BMD on below 75% of Korean RDA. Stepwise multiple regression analysis revealed that several dietary factors were influence on BMD. MAR on femoral neck BMD of children and elderly subjects was the highest influence factor. Beyond this, the most influential dietary factors on BMD were the vitamin A, total Ca and vegetable Ca. The above results have confirmed that dietary factors influence BMD in various age groups. Energy, protein, Ca, P, Fe, thiamin, riboflavin, niacin, vitamin C as well as MAR were important dietary factors influencing BMD. The results of this study revealed that people who received sufficient nutrients intake showed healthy bone status. The MAR mainly influenced the bone health status.

Objectives: Osteoporosis is the most common metabolic disease of the bone, and is one of the most important major public health problems world wide. It is more occurred in female than male, but as the osteoporosis of men is increasing, therefore bone fractures of men are increasing. So we investigated the factors which are related to Bone Mineral Density(BMD) of male for prevention of osteoporosis. Methods: We measured the Bone Mineral Density(BMD) of lumbar spine($L_2$-$L_4$) and femoral neck in 5198 male, using dual energy X-ray absorptionmetry(DEXA; DPX-alpha). And then we analysed the 8 factors - age group, bone mass index(BMI), amount of smoking, drinking, exercise, and fast blood sugar, gastric disease, thyroid disease - which are related to BMD of male. Results: 1. In age group according to ${\ll}$Hwangjaenaekyong Somun, 黃帝內徑 素問${\gg}$, T-score was the highest at 17-24(三八歲) years group and decreased rapidly after 57-64(八八歲) years group in both lumbar spine($L_2$-$L_4$) and femoral neck. Therefore we concluded that T-score of male in lumbar spine($L_2$-$L_4$) and femoral neck change according to age group in ${\ll}$Hwangjaenaekyong Somun, 黃帝內徑 素問${\gg}$. 2. In BMI(body mass index), T-score of lumbar spine($L_2$-$L_4$) and femoral neck were the highest in obese group than non-obese group. In comparison of age group according to BMI, T-score of lumbar spine($L_2$-$L_4$) was significant difference in 17-72 years group and T-score of femoral neck was in 25-72 years group. 3. In exercise, T-score of lumbar spine($L_2$-$L_4$) and femoral neck was increasing as exercising more. In comparison of age group according to exercise, Both T -score of lumbar spine and femoral neck were significant difference in 25-72 years old. 4. T-score of lumbar spine($L_2$-$L_4$) was the highest in men who have taken exercise daily, and T-score of femoral neck was the highest in men who have taken exercise 1-3 times for a week. Conclusions : The age group in ${\ll}$Hwangjaenaekyong Somun, 黃帝內徑 素問${\gg}$ is related to BMD of men. And risk factors - BMI, exercise - are related to BMD of men. Therefore we expect that this study will help for prevention of osteoporosis of men.
