Immediate dental implant placement with a horizontal gap more than two millimetres: a randomized clinical trial

The purpose of this study was to evaluate the horizontal dimensional changes in buccal alveolar bone immediately after dental implant placement in the upper premolar area with horizontal gaps >2 mm. A total of 48 patients were enrolled in this randomized clinical trial and were randomly assigned to one of three groups. Group I (flap with graft; n = 16) patients received an immediate implant with bone graft, membrane, and primary flap closure. Group II (flap without graft; n = 16) patients received an immediate implant with primary flap closure only. Group III (flapless without graft; n = 16) patients received an immediate implant without graft, membrane, or primary closure. Cone beam computed tomography (CBCT) scans were obtained preoperatively, immediately after implant placement, and at 6 months postoperative to evaluate horizontal dimensional changes in the buccal alveolar bone. Pain intensity was measured using a numerical rating scale. CBCT examinations revealed that bone had filled the horizontal gap in all three groups. Group II showed the greatest horizontal dimensional changes in the buccal alveolar bone, followed by group I. The least amount of change was recorded for group III. Furthermore, significantly less postoperative pain was recorded in group III when compared to the other groups. Short-term results suggest that the ‘flapless without graft’ technique shows similar results to the ‘flap with graft technique’ for immediate implant placement in the maxillary premolar extraction site with a horizontal gap >2 mm, when the bone plate is intact.     

Prevalence and treatment gap of active convulsive epilepsy: A large community-based survey in rural West China

PurposeActive convulsive epilepsy (ACE) impacts patients greatly, especially in low-income countries where patients do not receive appropriate treatment. In the present study, we measured the prevalence and treatment gap (TG) of ACE in rural West China.MethodsSix rural areas in West China that have a total population of 3,541,319 were selected to conduct prevalence and TG estimates of ACE via a clue survey from 2007 to 2009. Clue survey here is a community-based screening strategy among defined population which requires employed well-trained local physicians//health workers to collect all clues available to discover/identify/recruit patients within a study period. Questionnaire-based interviews were used for the identification of ACE patients, and information was obtained during the survey. Prevalence and TG of ACE were calculated.ResultsA total of 6547 patients with ACE were identified. The estimated prevalence of ACE was 1.8 per 1000 in the general population, with the prevalences in males and females determined to be 2.0 and 1.7, respectively (p < 0.001). The TG in the general population was 66.3%, and it was 66.6% and 66.0% in males and females, respectively (p > 0.05). The TG figures dropped with advancing age and increased above 30 years of age. Patients aged 60 years or older had the largest TG (77.8%); those with disease course less than 10 years showed a larger TG and those who experienced two to five seizures annually had a significantly larger TG (70.6%). Additionally, only 63.9% of the ACE patients included in the study were aware of the disease and had consulted a doctor.ConclusionsThere exists a large TG of ACE in West China rural areas. Majority of those ever consulted a doctor but failed to receive or adhere to an appropriate treatment program. Management including public education as well as training of local physicians were necessary to fill that gap.     

Disability and voting

BackgroundFor millions of people with disabilities in the United States, exercising the fundamental right to vote remains a challenge. Over the last few decades, the U.S. government has enacted several pieces of legislation to make voting accessible to individuals with disabilities.ObjectiveWe examine trends in self-reported voting rates among people with and without disabilities to uncover evidence for the effects of these policies on political participation. We also explore what policy change is necessary to encourage people with disabilities to vote by investigating whether the participation rates vary by the types of disabilities.MethodsWe analyze the Current Population Survey (CPS) data in the years of presidential elections for the period of 1980–2008.ResultsOur analysis shows that the population aged 18–64 with work-preventing disabilities has been persistently less likely to vote compared to the corresponding population without such disabilities. In addition, individuals with cognitive and mobility impairments have the lowest rates of electoral participation. The gap in the likelihood of voting in-person between people with and without disabilities is considerably larger than the gap in the likelihood of voting by-mail, regardless of the types of impairments that they have.ConclusionsThe participation gap between people with and without disabilities did not decrease over the last three decades despite the presence of federal laws that aimed at removing barriers for voting.     

Comparison of two tests of auditory temporal resolution in children with central auditory processing disorder,adults with psychosis,and adult professional musicians

Abstract

Objective: Evaluate auditory temporal resolution threshold outcomes across three different populations. Design: Two commercially available tests of auditory gap detection (Random gap detection (RGDT) test, and Gaps-in-noise (GIN) test) were administered to all participants. Study sample: Adult professional musicians (APM) (N = 11, age range 28–61 years); children with central auditory processing disorder (CAPD) (N = 22, age range 7.5–17 years); and first episode psychosis patients (FEP) (N = 17, age range 18–48 years). Results: It was not possible to calculate a threshold for the RGDT for 13 of 22 children with CAPD and for 7 of 17 adults with FEP due to response inconsistency. Analysis of variance (ANOVA) excluding cases that produced inconsistent RGDT results showed that only RGDT thresholds differed across groups (F = 8.73, p = 0.001). Three t-tests comparing test means within group revealed statistically significant differences between the gap detection thresholds obtained with the RGDT vs. the GIN for each group. No significant correlations were seen between RGDT and GIN. Conclusion: Lower/better gap detection thresholds and smaller standard deviations were obtained using the GIN in all three groups. Lack of correlation between the two tests suggests that they may measure different processes.     

Non-metallic implant for patellar fracture fixation: A systematic review

IntroductionDespite good clinical outcome proposals, there has been relatively little published regarding the use of non-metallic implant for patellar fracture fixation. The purpose of the study was to perform a systematic literature review to summarize and evaluate the clinical studies that described techniques for treating patella fractures using non-metallic implants.MethodsA comprehensive literature search was systematically performed to evaluate all studies included in the literature until November 2015. The following search terms were used: patellar fracture, patella suture, patella absorbable, patella screw, patella cerclage. Two investigators independently reviewed all abstracts and the selection of these abstracts was then performed based on inclusion and/or exclusion criteria.ResultsA total of 9 studies involving 123 patients were included. Patients had a mean age of 33.7 years and were followed up for a mean of 18.9 months. The most common method for fracture fixations included the use of suture material. Good clinical outcomes were reported among all studies. Thirteen patients (10.5%) presented complications, while 4 patients (3.2%) required additional surgery for implant removal.ConclusionThere is a paucity of literature focused on the use of non-metallic implant for patellar fracture fixation. However, this systematic review showed that non-metallic implants are able to deliver good clinical outcomes reducing the rate of surgical complications and re-operation. These results may assist surgeons in choosing to use alternative material such as sutures to incorporate into their routine practice or to consider it, in order to reduce the rate of re-operation.
