PURPOSE: We evaluated the usefulness of quantitative spiral CT to predict postoperative lung function in patients undergoing pulmonary resection. MATERIALS AND METHODS: Fourteen patients in whom pneumonectomy or segmentectomy were performed underwent preoperative chest spiral CT and pulmonary function test(PFT). Six patients underwent postoperative follow-up PFT. Ten patients underwent preoperative radioisotope(RI) lung perfusion scan. Preoperative CT data were postprocessed with contiguous pixel method ranged from -9107HU to -500HU to quantify total functional lung volume(TFLV) and regional volume to be resected(RFLV). Postoperative lung function was predicted by following formula;Predicted postoperative PFT value=preoperative PFT x 1-RFLV/TFLV). CT predicted value was compared with postoperative measured PFT value and those value of RI perfusion scan. RESULTS: CT predicted values were very close to postoperative measured value and RI predicted value, and were correlated well with postoperative measured values (FVC: r=0.988, P<0.001 ;FEV1: r=0.994, P<0.001) and RI predicted values (FVC :r=0.976, P<0.001 ;FEVl: r=0.974, p<0.001). CONCLUSION: Quantitative spiral CT was useful to predict postoperative lung function and could be an effective alternative to RI perfusion scan.

OBJECTIVES: Seoul-Activities of Daily Living(S-ADL) was developed to assess elderly person's basic activities of daily living. This study aims to develop standardized ADL assessment scale and confirm the reliability and validity of the S-ADL. METHODS: It was participated in 336 controls and 145 patients diagnosed Alzheimer's disease. RESULTS: In controls, it was statistically significant to age, but not sex, education, region and presence of spouse. Also, reliability and validity were statistically significant. Principal axis factoring analysis revealed three factors that accounted for 66.67% of the total variance(1.self-care/hygiene, 2.ambulation, 3.toileting). According to each CDR stage, there were significant difference, except for CDR 0.5 and CDR 1 suggesting early dementia. Particularly, it was remarkable for functional impairment in CDR 2 and CDR 3 suggesting moderate to severe dementia. The order of the loss of function was (1) self-care/hygiene, (2) toileting, and (3) ambulation. CONCLUSIONS: Our study showed that the S-ADL could be a very reliable and valid tool for the assessment of functional disabilities of Korean dementia patients. Particularly, S-ADL would be useful in assessing daily function of moderate to severe AD.

One of the treatment options for edentulous state patients with residual ridge resorption is implant overdenture using milled bar and attachment. It not only provides improved retention and stability but can also reduce the coverage of palatal surface. In addition, when a small number of implants are used, milled bar has the effect of being splinted between implant fixtures, which makes it mechanically advantageous under functions such as mastication. The patient in this case was a maxillary edentulous state patient with a considerable amount of residual alveolar bone resorption after removing the existing failed implants. Three implants were planted on both sides and an implant overdenture was fabricated using milled bar and ADD-TOC attachment.

Excessive crown height space increases can cause crestal bone loss and screw loosening after prosthesis is placed. Milled bar and implant overdenture can be used as a treatment method for partially edentulous patients who have severe alveolar bone loss and excessive crown height space. Milled bar can provide primary splinting effect and stability between implants. Also, milled bar with additional retention device such as Advanced Dental Device-Treatment Of Choice (ADD-TOC) and magnet can provide additional retention force for implant overdenture. In this case, the patient has a partially edentulous mandible that has severe alveolar bone loss and multiple number of teeth loss after excision due to leiomyosarcoma. Because of the long-term loss of mandibular molars, the opposing teeth were extruded. Maxillary left molars were corrected to the occlusal plane through molar intrusion, and mandibular left molar region were treated with implant overdenture, using milled bar with ADD-TOC and magnet after implant placement. The clinical result was satisfactory on the aspect of esthetic and masticatory function.

PURPOSE: We made investigation into the etiology, clinical manifestations, laboratory findings, treatments, outcomes, prognosis and prognostic factors of acute myocarditis in children. METHODS: We have reviewed the medical records of the patients who were admitted to the Chonbuk National University Hospital for recent 10 years. Patients were divided in two groups with base on the outcomes. One is recovery group and the other is mortality group. And we analyzed the clinical findings and compared between two groups. RESULTS: Ten of 27 patients were expired with fulminant myocarditis or complication of acute myocarditis. Seventeen patients were recovered. Left ventricular fractional shortening on the echocardiogram was a valuable prognostic factor. Seventeen patients were treated with IVIG. Seven patients were evaluated the viral etiology. Coxsackie B5, coxsackie B3, coxsackie A10 and adenovirus were detected. CONCLUSION: Left ventricular fractional shortening was a valuable prognostic factor. It is necessary to research antegrade multicenter study about acute myocarditis.

Polypeptide growth factors belong to a class of potent biologic mediators which regulate cell differentiation, proliferation, migration and metabolism. IGF-I is polypeptides secreted by skeletal cells and is considered as regulators of bone formation. The purpose of this study is to evaluate the effects of IGF-I on bone nodule formation and alkaline phosphatase activity of MC3T3-E1 cells. MC3T3-E1 cells were seeded at 1x10(4) cells/well, 1x10(5) cells/well in alpha-modified Eagle medium containing 10% fetal bovine serum, 10 mM beta-glycerophosphate and 50microgram/ml of ascorbic acid. Before 48 hours of indicated time, medium were changed with serum free medium. After 24 hours, 0.1, 1, 10 ng/ml IGF-I were added to the cells and cultured for 3, 7, 14, 21, 28 days. And histochemical analysis was done and ALP activity was measured and was expressed as nmol/min/mg of protein. The bone nodule formation in MC3T3-E1 cells of IGF-I was seen at 21, 28 days, but there were no difference between control group and experimental groups. The ALP activity decreased when it is compare to control 2 group except for 1 ng/ml, 10 ng/ml IGF-I of 21-day-groups and 1 ng/ml IGF-I of 28-day-groups. Dose response effects of IGF-I of ALP activity in MC3T3-E1 cells were seen the highest ALP activity at 1ng/ml until 21days and the highest ALP activity at 10 ng/ml of 28 daygroups. The peak times were seen at 7-day group, 14-day group on control group and experimental group respectively, and 1 ng/ml group was the highest ALP activity. From the above results, IGF-I was not seen notable effect on bone nodule formation and decreased ALP activity of MC3T3-E1 cells but the use of IGF-I to mediate biological stimulation of MC3T3-E1 cells shows promise for future therapeutic application.

PURPOSE: Diabetic foot gangrene has a high morbidity rate and a great influence on the quality of life. Amputation is an appropriate treatment if conservative treatment is impossible according to the severity of gangrene and infection. The purpose of this study was to evaluate the usefulness of preoperative percutaneous transluminal angioplasty for the postoperative outcome. MATERIALS AND METHODS: From February 2013 to April 2016, among 55 patients with diabetic foot gangrene, who require surgical treatment, percutaneous transluminal angioplasty was performed on patients with an ankle brachial index (0.9 and stenosis) 50% on angiographic computed tomography. The study subjects were 49 patients, comprised of 37 males (75.5%) and 12 females (24.5%). The mean age of the patients was 70.0±9.6 years. The treatment results were followed up according to the position and length of the lesion and the changes during the follow-up period. RESULTS: As a result of angiography, there were 13 cases of atherosclerotic lesions in the proximal part, 11 cases in the distal part and 25 cases in both the proximal and distal parts. As a result of the follow-up after angiography, in 13 patients, the operation was not performed and only follow-up and dressing were performed around the wound. Sixteen patients underwent debridement for severe gangrene lesions and 20 patients, in whom the gangrene could not be treated, underwent amputation (ray amputation or metatarsal amputation, below knee amputation). CONCLUSION: Preoperative percutaneous angioplasty in diabetic foot gangrene patients with peripheral vascular occlusive disease is simple, and 59.2% of the patients with diabetic foot gangrene could be treated by conservative treatment or debridement.
