BACKGROUND: Passive smoking is an important worldwide public health issue. In many Korean studies, parental smoking has been reported to be associated with reduced pulmonary function in children. But few studies have evaluated the effects of passive smoking on pulmonary function in adults. Therefore, we looked into this association in the study. METHODS: Participants in the study included non-smoking, healthy men (n=46) and women (n=326) from rural Korea enrolled from June to December 2006. Exposure to passive smoking was assessed by a self-administered questionnaire, and standardized pulmonary function tests were performed. RESULTS: There were significant reductions in forced expiratory volume in 1 second (FEV1, % of predicted) and forced mean expiratory flow rate 25-75% (%) among the men exposed to passive smoke compared with those not exposed (55.7 vs 75.8, P=0.010; 33.9 vs 58.6, P=0.029, respectively). There were significant reductions in FEV1 among men exposed at both workplace and home compared with men exposed only at either workplace or home (42.8 vs 49.3, 64.6; P=0.034). No significant difference in pulmonary function was found between women exposed to passive smoke compared those not exposed. There were, however, reductions in FEV1 and FEV1/forced vital capacity among the women exposed at workplace. Regression analysis showed that passive smoking negatively affected lung function, which were not statistically significant. CONCLUSIONS: Exposure to environmental tobacco smoke, particularly at the workplace, adversely affects pulmonary function in adults.

PURPOSE: The aim of this study was to evaluate the use of dehydrated human amnion/chorion membrane (dHACM) to repair perforated sinus membranes in rabbits. METHODS: Bilateral surgical windows (7.5-mm diameter) were prepared on the nasal bones of 14 rabbits. Standardized circular perforations (5-mm diameter) were made in the sinus membrane by manipulating implant twist drills. The perforated sinus membranes were repaired using dHACM or a resorbable collagen membrane (CM). The negative control (NC) group did not undergo perforated sinus membrane repair, while the positive control (PC) group underwent sinus augmentation without perforations. The same amount of deproteinized porcine bone mineral was grafted in all 4 groups. After 6 weeks, micro-computed tomography (micro-CT) and histomorphometric evaluations were conducted. RESULTS: The micro-CT analysis revealed that the total augmented volume was not significantly different among the groups. In the dHACM group, newly formed bone filled the augmented area with remaining biomaterials; however, non-ciliated flat epithelium and inflammatory cells were observed on the healed sinus membrane. Histometric analysis showed that the percentage of newly formed bone area in the dHACM group did not differ significantly from that in the CM group. The dHACM group showed a significantly higher percentage of newly formed bone area than the NC group, but there was no significant difference between the dHACM and PC groups. CONCLUSIONS: dHACM could be a feasible solution for repairing sinus membrane perforations that occur during sinus floor augmentation.

The metal ceramic crown is currently the most popular complete veneer restoration in dentistry, but in many cases, the metal cervical collar at the facial margin is unesthetic and unacceptable. Facial porcelain margin has been used in place of it. But this dose not solve the problems, such as dark gingival discoloration and cervical opaque reflection of porcelain veneer. Recently, metal copings which were designed to terminate its labio-cervical end on the axial walls coronal to the shoulder have been clinically used to solve the esthetic problem of metal ceramic crown. But in this design, porcelain veneer of labio-cervical area which is not supported by metal may not be able to resist the stress during cementation and mastication. The purpose of this study was to evaluate fracture strength and fractured appearance of crowns according to different coping designs. A resin maxillary left central incisor analogue was prepared for a metal ceramic crown, and metal dies were made with duplication mold. Metal copings were made and assigned to one of four groups based on facial framework designs: group 1, coping with 0.5mm metal collar; group 2, metal extended to the shoulder; group 3, metal extended to 1 mm coronal to the shoulder; group 4, metal extended to 2mm coronal to the shoulder. Copings and crowns were adjusted to be same size and thickness, and cemented to metal dies with zinc phosphate cement by finger pressure. Fracture strength was measured with Instron Universal Testing Machine. Metaldies were anchored in Three-way-vice at 3mm below finish line and at 130degree inclined to the lone axis of the crown. Load was directed lingually at 2mm below midincisal edge. Load value at initial crack and at catastrophic fracture was recorded. The results obtained were as follows: 1. Fracture strength values at initial crack were higher in groups 1, 2 than in groups 3, 4 but this difference was not statistically significant(P<0.05). 2. Conventional metal collared crown had greater catastrophic fracture strength than any other collarless crowns. 3. The greater the labial metal coping reduction, the lower the catastrophic fracture strength of crowns but when more than 1mm of labial metal reduction was done, the difference in strengths was not statistically significant(p<0.05). 4. The strongest collarless coping design was group 2.

STUDY DESIGN: A retrospective analysis was performed on 40 patients who had had previous lux bar spine surgeries. OBJECTIVE: To determine what factors most influenced surgical outcome and to analyze results in a series of revision lumbar surgeries. SUMMARY OF BACKGROUND DATA: Satisfactory surgical outcome of the revision lumbar surgery range from 28% to 82% and are rarely comparable to primary surgery. Many factors predicting outcome from repeat lumbar surgery haute been listed. METHODS: Forty patients were analyzed who had had previous lumbar surgeries. The patients were classified into 5 groups according to diagnosis: 3 Infection,5 instability,8 nonunion, 14 HNP and 10 spinal stenosis. of 40 patients,33 patients(82.5%) underwent fusion with instrumentation for repeat surgery. Their clinical course was followed for a minimum of 1 year. The number of surgery on each mpatient was 1.3 times on an average. RESULTS: Overall, 80% of patients had a satisfactory result. Obviously extruded or sequestrated HNP in MRI findings, complete block of contrast with severe radiculopathy and/or myelopathy in spinal stenosis, complete decompression, neurolysi s and fusion with instrumentation, and longer than 6 month pain relief after precious surgery were correlated with satisfactory outcome. However, the number of precious operation, age, repair of pseudarthrosis , no abnormality at surgery and combined multiple degenerative joint disease were significantly correlated with poor surgical outcome. The most common complication during repeat surgery was dural tear in 5 cases(12.5%). CONCLUSIONS: Success rate of revision surgery was low as compared to primary operation. Therefore, erroneous diagnosis and faulty surgical technique understandably lead to failure, and precise attention to preoperative and intraoperative detail can minimize these sources of error.

BACKGROUND: This study used MDS-HC 2.0 (Minimum Data Set-Home Care) to analyze the health and the state of function of the traveling health objects. This study was intended to make use of it with the basic materials for providing them with traveling health service suited for the requirement on the health of the traveling health objects. METHODS: The subjects of this study were 1160 people (over 65 years) living under management control of local Health Center from September 7th to October 3th, 2006. This study was analyzed with inter RAI program & SPSS/WIN 10.0, chi-square -test, t-test, and ANOVA. RESULTS: The result showed that 8.97 CAPs per an elderly person was identified and the subjects over 60% had an injury problem from a fall, health prevention service, vision, IADL, pain, and cognition. The number of CAPs in general was high in higher age and the less educated, and those without a job. But, in subjects that had a life partner and a spouse, the number of CAPs was low. In CAPs by the distinction of sex, CAPs which was much more in man than women in statistics were the improvement of health, the abuse of alcohol and drinking wine, bedsore, and the weak supply system. CAPs which women had much more were the function of the heart and the lungs, pain, the performance of the doctor's advice, health prevention service, and incontinence of urine and insertion of catheter. According to the results comparing CAPs by the level of the ADL, the number of CAPs was shown that the group of ADL 2 was higher than group ADL 1. The matter in which the traveling health service had to be applied in all both ADL1 and ADL2 was injury from a fall, health prevention service, and vision. Conculsion: MDS-HC is applicable to decide the care needs for health and social service supplies. The results can be further applicable for careplan, and referral criteria in continuum of care service over long-term care spectrums.
