AbstractThe purpose of this study is to evaluate the efficacy and safety of direct right atrial catheter insertion for hemodialysis in patients with multiple venous access failure. We retrospectively evaluated the charts of 27 patients with multiple venous access failure who had intra‐atrial dialysis catheter placement between October 2005 and October 2010 in our clinic. Permanent right atrial dialysis catheters were placed through a right anterior mini‐thoracotomy under intratracheal general anesthesia in all patients. Demographics of the cases, the patency rates of hemodialysis via atrial catheterization, existence of any catheter thrombosis, and catheter‐related infections were documented and used in statistical analysis. Seventeen women (63%) and 10 men (37%) with the mean age of 59.0 ± 7.1 years (47–71) were enrolled in this study. Chronic renal failure was diagnosed for the mean of 78.9 ± 24.3 months (33–130). Five patients (18.5%) died. Ventricular fibrillation and myocardial infarction were the causes of death in the early postoperative period in two patients. Two of the remaining three patients died because of cerebrovascular events, and one patient died because of an unknown cause. Ten patients (37%) had been using anticoagulate agents (warfarin) because of concomitant disorders such as deep vein thrombosis, operated valve disease, and arrhythmias. Catheter thrombosis and malfunction was determined in three cases (11.1%). Intra‐atrial hemodialysis catheterization is a safe and effective life‐saving measure for the patients with multiple venous failure and without any possibility of peritoneal dialysis or renal transplantation.

AbstractKimura disease is a rare benign inflammatory disorder presenting as subcutaneous masses or lymphnodal mass in the cervical region. Kimura disease is reported sparsely in patients on maintenance hemodialysis. We report an unusual location of Kimura disease in a patient on maintenance hemodialysis, who had a prolonged, persistent asymptomatic eosinophilia.

AbstractObjectiveThe current study aimed to evaluate the osteogenic potential of electrosprayed organic and non‐organic surface coatings in a gap‐implant model over 4 and 12 weeks of implantation into the dog mandible.Material and methodsSixteen Beagle dogs received experimental titanium implants in the mandible 3 months after removal of left premolars (P2, P3 and P4). Three types of implants were installed in each animal: non‐coated implant, nano‐CaP coated implant and implant with type 1 collagen coating. Both micro‐CT and histomorphometry were used to evaluate peri‐implant bone response after implantation periods of 4 and 12 weeks. The bone area percentage was assessed histomorphometrically in three different zones (inner: 0–300 μm; middle: 300–600 μm; and outer: 600–1000 μm) around the implant surface. Bone‐bridging of the gap was also calculated for each sample.ResultsFour weeks after implantation, nano‐CaP and collagen‐coated implants showed significantly higher bone volume (BV) in the inner zone compared with non‐coated implants (P < 0.05 and P < 0.01). After 12 weeks, histomorphometric analysis showed comparable amounts of BV between all experimental groups. Also, no significant difference was found in the BV, as measured using micro‐CT, between the implant groups. Absolute bone ingrowth measurements were highest for collagen‐coated implants, but these differences were not significant.ConclusionThe obtained data failed to provide a consistent favourable effect on bone formation of the collagen coating over 3 months of implantation. It is concluded that the source of the collagen as well as the limited osseous environment overshadowed a possible effect of the applied implant surface modifications. Similarly, the tested nano‐apatite surface coating did not improve peri‐implant bone ingrowth into a gap‐implant model.

AbstractObjectivesThe aim of this prospective cohort study was to compute the long‐term clinical survival and complication rates of alumina‐toughened zirconia abutments used for implant‐supported restorations and to evaluate the effects of several clinical variables on these rates.Material and methodsFrom May 1998 to September 2010, 213 patients aged 18 years or older were recruited. The patients received 611 external hex implants and 328 implant‐supported fixed restorations using alumina‐toughened zirconia abutments. During the follow‐up, each restoration was coded as a dental event, which included loosening or fracture of abutment screws, and abutment fracture. From the coded data, the effects of the investigated clinical variables—restored area (anterior/posterior), number of prosthodontic units (one/two units or over), prosthesis type (single‐unit/multiunit without pontic/multiunit with pontic), implant system, and patient gender—on the survival of the abutments were evaluated. Survival analysis using Kaplan–Meier method and Cox proportional hazard model was applied. The 5‐year survival and complication rates of the abutments were assessed.ResultsThe number of prosthodontic units and the type of prosthesis had a significant association with complication rates (P < 0.05). Kaplan–Meier survival analysis estimated that the cumulative 5‐year complication rate of the abutments used in single restorations was 19.7%. Multiunit‐fixed dental prostheses without and with pontics had complication rates of 3.9% and 3.8%, respectively. The 5‐year survival rate of the abutments was more than 95%, regardless of the type of prosthesis.ConclusionsAlumina‐toughened zirconia abutments are likely to exhibit excellent long‐term survival in clinical use for fixed restorations. Single tooth replacement with the abutment at the molar region may require special care and extra attention.

AbstractBackgroundIn the replacement of missing teeth, a paradigm shift is currently observed with immediate implant placement and/or restoration, particularly in the aesthetic zone. In molar sites, however, anatomical, occlusal and biomechanical considerations remain deterrent factors influencing the outcome of this treatment paradigm. The aim of this report was to evaluate immediate placement and immediate restoration of strongly tapered wide‐diameter implant in fresh mandibular molar extraction sockets.MethodsTwenty‐four 8‐ or 9‐mm diameter implants were placed in either a fresh molar extraction socket or a healed site. All the implants received provisional crowns within 48 h. The provisional crowns were replaced with full ceramic crowns after 8 weeks of implant placement.ResultsThe overall implant success rate after 1 year of service for the 24 implants in two treatment groups was 75%. Success rates were 83.3% and 66.7% for the delayed and immediate placement groups respectively, with no significant difference observed between the two groups (P = 0.35). Implant stability measurements identified the immediately placed implants to be more stable immediately after surgery than delayed placed implants. In contrast, the delayed placed implants were more stable after 8 week healing time.ConclusionsThe rehabilitation of single missing mandibular molars by immediately placed and restored wide‐diameter implants was associated with a relatively high failure rate.

AbstractObjectivesThe aim of the present study was to present the results of patients followed for at least 3 years who underwent horizontal distraction osteogenesis DO and a final implant prosthesis.Material and MethodsA total of 13 sites in 12 patients (three men, nine women; mean age 45.4 years, range 21–63 years) who presented with severe horizontal atrophy of a partially edentulous maxilla or mandible were treated using horizontal DO. The horizontal distraction device was set on the transport bone which was osteotomized as bone splitting method and fixed to the segment using microscrews.ResultsThe median of latency period was 9 days (range: 7–17); the median of amount of device activation was 5.6 mm (range: 4.4–9.6); the median of distraction period was 14 days (range: 8–24); and the median of consolidation period, from the end of activation until implant placement, was 13 weeks (range: 11–20). The median of actual gain in bone width at the end of the consolidation period was 3.6 mm (range: 1.1–5.6). A total of 35 implants were inserted in the augmented area with primary implant stability. The median of follow‐up from the start of prosthetic loading was 5.4 years. Consequently, the implant survival and success rates were 100% and 94.2%, respectively.ConclusionThis article reports the long‐term results of horizontal alveolar DO using a mesh device for patients with an atrophic alveolar region. Our results confirm that this technique is a predictable and effective regenerative procedure for implant preprosthetic treatment in patients with severe horizontal atrophy of the alveolar ridge.

AbstractBackgroundImplant dentistry in the posterior maxilla often requires bone augmentation. The gold standard, autogenous bone graft, requires additional surgery with associated morbidity, while bone biomaterials may not support relevant bone formation. Recombinant human bone morphogenetic protein‐2 (rhBMP‐2) in an absorbable collagen sponge (ACS), however, induces significant, clinically relevant bone formation in several settings including the maxillary sinus floor.ObjectiveThe objective of this study was to compare local bone formation and osseointegration following maxillary sinus augmentation using rhBMP‐2/ACS or a particulate autogenous cancellous bone graft obtained from the iliac crest in conjunction with immediate placement of dental implants.Materials and methodsBilateral sinus augmentation using an extraoral approach including rhBMP‐2 (0.43 mg/ml)/ACS or the autogenous bone graft, alternated between left and right sinus cavities in five adult male Yucatan mini‐pigs, was performed. Two 12‐mm dental implants were inserted into the sinus wall protruding approximately 8 mm into the sinus cavity. Surgical sites were closed and sutured in layers; block biopsies collected for histometric analysis at 8 weeks.ResultsrhBMP‐2/ACS induced bone of significantly greater and consistent quality compared with the iliac crest autogenous bone graft; bone density averaging 51.9 ± 3.0% vs. 32.9 ± 2.5% (P = 0.01). However, there were only numerical differences in augmented bone height (9.3 ± 0.5 vs. 8.6 ± 0.7 mm) and bone‐implant contact (37.4 ± 3.0% vs. 30.7 ± 5.9%) between treatments.ConclusionrhBMP‐2/ACS induces bone of superior quality compared with an iliac crest particulate autogenous cancellous bone graft when used for maxillary sinus augmentation, and should perhaps be considered the new standard for this indication.

AbstractAimPeriodontal disease is highly prevalent and severe in diabetic patients, and is considered one of the diabetic complications. To elucidate how periodontitis progresses in diabetes, we examined an animal model of periodontitis in diabetic rats.Materials and MethodsTwo weeks after the induction of diabetes by streptozotocin, surgical nylon thread was ligated around the cervical portion of the unilateral maxillary second molar to induce periodontitis. Periodontitis was evaluated 2 weeks after the ligation by gingival blood flow, mRNA expressions, Western blot analysis, histological examination and micro CT.ResultsLigation‐induced severe periodontitis in the diabetic rats, which was apparently shown by the increase of TNF‐α and iNOS mRNA expressions and inflammatory cell infiltration in the gingiva and alveolar bone loss. The number of nitrotyrosine, a footprint of nitrosative stress, ‐positive cells was significantly higher in the periodontitis of the diabetic rats compared with that in the normal rats. Western blot analysis confirmed that the nitrotyrosine was increased in the periodontitis of the diabetic rats.ConclusionsThis is the first study to confirm increased nitrosative stress due to periodontitis in diabetic rats. Nitrosative stress may play a crucial role in the exacerbation of periodontitis in diabetic patients.

Exploring the quality of life after denture‐wearing within elders in KaohsiungObjective:  The objective of the research is to investigate whether the elderly people’s quality of life get improved after denture wearing.Material and methods:  About 1600 elderly persons, over 65 years old, were sampled as the research target. The overall response rate was 71.62%. The tool of research is a structural questionnaire Oral Health Impact Profile (OHIP) that was used to measure the oral health–related quality of life. Individual’s satisfaction of denture wearing divides into three groups: edentulous individuals who are satisfied with denture wearing, edentulous individuals who are not satisfied with denture wearing and dentulous individuals.Results:  The result shows the eight variables, which are oral health condition, frequency of snacks‐eating, age, frequency in participation in social activities, instrumental activities of daily living (IADL), vision, satisfaction with life and physical functions, have significant influence on total OHIP score.Conclusions:  Although being edentulous, if the elderly are satisfied with their denture, the quality of life can be maintained and not affected by oral health problems. It is suggested that the further researches can include more relevant factors when in a discussion on the oral health–related quality of life, especially, the subjective perception of individual’s feeling.

Women’s Agency in Gender‐Traditional Religions: A Review of Four Approaches
Authors: Burke Kelsy C. 
Published: January 2012

AbstractThe concept of agency is useful for feminist research on women in gender‐traditional religions. By focusing on religious women’s agency, scholars understand these women as actors, rather than simply acted upon by male‐dominated social institutions. This article reviews the advantages and limitations of feminist scholarship on the agency of women who participate in gender‐traditional religions by bringing into dialog four approaches to understanding agency. The resistance agency approach focuses on women who attempt to challenge or change some aspect of their religion. The empowerment agency approach focuses on how women reinterpret religious doctrine or practices in ways that make them feel empowered in their everyday life. The instrumental approach focuses on the non‐religious positive outcomes of religious practice, and a compliant approach focuses on the multiple and diverse ways in which women conform to gender‐traditional religious teaching. This article concludes by discussing the future direction of scholarship.
The Animal Rights Movement in Theory and Practice: A Review of the Sociological Literature
Authors: Munro Lyle 
Published: January 2012

AbstractTraditionally, philosophers have had most to say about the ethics of our treatment of non‐human animals (hereafter animals); it is only in recent years that social scientists have engaged with issues concerning humans and other animals. However, in the sociological literature and more generally in the emerging field of Human–Animal Studies (HAS), evidence of interest in the animal protection movement is slight. This review of Eliasian theory, Marxist realism, feminism, ecofeminism, and social constructionist theory – along with key activist approaches to animal activism and advocacy – indicates the theoretical richness of the topic that is nonetheless empirically poor. The animal protection movement is referred to here simply as the animal movement or where appropriate, as one of its three strands – animal welfare, animal liberation and animal rights. The article concludes with a discussion of how social movement theory (the ‘why’) and practice (the ‘how’) might be enhanced by social movement scholars working in collaboration with animal activists.
