Osteoporosis is a disease characterized by excessive bone loss or osteopenia particulary in the axial skeleton at the site of fracture, such as the spine and proximal femur. Since the strength of both spine and femur is directly proportional to the bone mass, this osteoporosis always increases the risk of fracture. In this study, to evaluate whether a simple measurement of femoral geometry and BMD value are related with hip fracture, we obtained DEXA Scan (Lunar Expert-XL) of hip by retrospective study. DEXA scan was measured on 70 control people and 17 hip fracture patients aged 50 or older. The result is I. The mean Ward BMD value of hip fracture group is significantly lower than control group (Hip fracture group: 0.52g/cm2, Control group: 0.67g/cm2 P=0.0001) 2. The mean L-spine BMD value of hip fracture group is significantly lower than control group (Hip fracture group: 0.81g/cm, Control group: 0.97g/cm2 P=0.0002) 3. The mean femur axis length of hip fracture group is longer than control group (Hip fracture group: 6.77g/cm2, Control group: 6.57g/cm2 P=0.006) As a conclusion, the measurement of BMD and hip axis length in DEXA scan is an effective method for screening the hip fracture risk patient and BMD value of femur, hip axis length and L- spine BMD value are strongly associated with hip fracture.

A 46 year-old female patient underwent cholecystectomy under general anesthesia. During the preoperative preparation, pulmonary edema developed from fluid overloading in the early septic condition. Pulmonary edema contributed significantly to the acute respiratory failure, which played a major role in the pathogenesis of multiple organ failure. For this condition, early surgical intervention is most important. After preoperative evaluaion, the authors anesthetized the patient with Morphine, used Enfluane intermitently, along with pancronium and oxygen and used endotracheal semiclosed circle absorption techniques with CMV incorporated PEEP. PEEP level was 5cm H2O. Inspired oxygen fraction was 1.0. Arterial oxygen tension increased from 62 torr to 183 torr despite the overt pulmonary edema. A-aDO2 was greater than 480 mmHg during the anesthesia of 2 hrs 40 minutes. For further treatment of pulmonary edema and postoperative respiratory care, synchronized IMV with PEEP, along with conventional methods for pulmonary edema and sepsis, were used in the ICU. After 6 days of intensive care, the patient was transferred to the general ward in good cardiovascular and respiratory function.

OBJECTIVE: To compare the scar formation and hand function between moist exposed burn ointment (MEBO) treatment and conventional skin graft in full thickness hand burns. METHOD: Prospective comparative study was done between MEBO treatment group and conventional skin graft group. Full thickness burn wound scars on dorsal hand were compared. Scars were assessed with the Vancouver scar scale and other objective measurement tools such as pigmentation, erythema, pliability, transepideramal water loss, thickness and perfusion. Hand function was evaluated by the Jebsen hand function test and Michigan Hand Function Questionnaire. RESULTS: Vancouver Scar scale showed significantly better scores in the MEBO group than in the conventional skin graft group. Scar thickness and transepidermal water loss were greater in the MEBO treatment group whereas pigmentation value was greater in the conventional skin graft group. There was no significant difference in the hand function between the two groups. CONCLUSION: MEBO application could be an alternative treatment to conventional skin graft treatment in full thickness hand burn wounds. In the future, more studies are yet to come how MEBO treatment may affect the skin condition of the burn injuries.

A finite element analysis has been utilized to analyze stress and strain fields and design a new configuration in orthopedics and implant dentistry. Load transfer and stress analysis at implant bone interface are important factors from treatment planning to long term success. Bone configuration and quality are different according to anatomy of expecting implantation site. The purpose of this study was to compare the stress distribution in maxilla and mandible according to implant length and bone engagement types. A three dimensional axi-symmetric implant model(Nobel Biocare, Gothenburg, Sweden) with surrounding cortical and cancellous bone were designed to analyzed the effects of bone engagement and implant length on stress distribution ANSYS 5.5 finite element program was utilized as an interpreting tool. Three cases of unicortical anchorage model with 7, 10, 13mm length and four cases of bicortical anchorage model with 5, 7, 10 and 13mm lenght were compared both maxillary and mandibular single implant situatiion. Within the limits of study, following conclusions were drawn. 1. There is difference in stress distribution according to cortical and cancellous bone thickness and shape. 2. Maximum stress was shown at the top of cortical bone area regardless of bone engagement types. 3. Bicortical engagement showed less stress accumulation when compared to unicortical case overall. 4. Longer the implant fixture length, less the stress on cortical bone area, however there is no difference in mandibular bicortical engagement case.

The aim of this study was to compare optic disc size obtained using the two methods Color polaroid photographs of optic disc of 130 normal subjects and 174 patients with glaucoma were evaluated by means of computeraided morphometry. In the first method, the optic disc size were calculated by applying the modified formula of an ellipse, where area=pi/4xthe horizontal diameterxthe vertical diameter. In the second method, we obtained optic disc size [] using the twelve radii that were measured every 30 degrees. Magnification effects of the eye and camera were corrected in the two methods. The measurements of the optic disc area(2.49mm2), cup area(1.01mm2) and neuroretinal rim area (1.49mm2) by the first method were significantly(P<0.003, Wilcoxon signed -rank test) different from the measurements by the second method(2.48mm2, 1.03mm2, 1.45mm2, respectively) (the average difference; 0.05+/-0.05mm2, 0.05+/-0.05mm2, 0.07+/-0.06mm2,respectively). The mean error for the neuroretinal rim area was 4.2+/-3.3% in the normal group and 7.5+/-8.5% in the glaucoma group(P=0.005). It increased with decreasing neuroretinal rim area and increasing visual field defects. Thus the magnification corrected measurements of the horizontal and vertical diameters and the modified formula of an ellipse can be used for a quick approximate estimation of the optic disc size, but cannot replace more accurate method of optic disc measurements using twelve radii.

PURPOSE: The purpose of this study is to identify the effects of telephonic counseling on burnout, depression, life satisfaction, and perceived physical health among family caregivers of older adults with dementia. METHOD: Subjects were randomly assigned into telephonic counseling group (n=21) and the comparison group (n=32). A weekly telephone counseling was conducted by research assistants for 12 weeks. T-test were used to answer the research questions. RESULT: 1) There were no significant differences between the two groups on the level of burnout, depression, life satisfaction, and perceived physical health after telephone counseling. 2) Spouse caregivers under the telephone counseling tended to report higher perceived physical health than comparison group at the post-test (t=-1.88, p=.08). Spouse caregivers under the telephone counseling tended to report higher emotional exhaustion and lower feeling of self achievement. 3) Daughter-in-law caregivers under telephone counseling showed increased feeling of self achievement, improved physical health condition, and decreased depression. CONCLUSION: This study showed potential effects of the problem-solving telephone counseling to improve perceived physical health and to reduce the level of burnout and depression. The findings suggest the necessity of screening most vulnerable subgroups of caregivers to increase the effectiveness of nursing intervention such as telephone counseling.

The penetrating atherosclerotic ulcer of the aorta resulting from the atherosclerosis of the aortic wall can clinically mimic type III aortic dissection, since both diseases produce the ulceration and dissection of aortic wall. However, their imaging features and pathophsiologies are distinctly different from each other. Familial hypercholesterolemia(FH) menifests overt hyperlipidemia that can results in premature atherosclerosis of the aorta as well as the coronary artery. We report a clinically and radiologically evident case of perntrating atherosclerotic ulcer of the descending thoracic aorta which was developed in a 36-year-oldd heterozygote FH male.
