Success rates for various graft materials in tympanoplasty e A review

Objectives:The aim of this paper is to review how successful each type of grafts is in tympanoplasty.Methods:Pubmed,Google and the Proquest Central Database at Kırıkkale University were queried using the keywords“graft”,“success”“tympanoplasty”,“success rate”with the search limited to the period 1955 to 2017.Results:Various types of graft materials including temporalis fascia,cartilage,perichondrium,periosteum,vein,fat or skin have been used in the reconstruction of tympanic membrane(TM)perforation.Although temporalis fascia ensures good hearing is restored,there are significant concerns that its dimensional stability characteristics may lead to residual perforation,especially where large TM perforations are involved.The“palisade cartilage”and“cartilage island”techniques have been stated to increase the strength and stability of a tympanic graft,but they may result in a less functional outcome in terms of restoring hearing.Smoking habits,the size and site of a perforation,the expertise level of the operating surgeon,age,gender,the status of the middle ear mucosa and the presence of myringosclerosis or tympanosclerosis are all important in determining how successful a graft is.Conclusion:Although temporal fascia is the most commonly used graft material for tympanoplasty,poor graft stability may cause failure.This failure is due to the inclusion of connective fibrous tissue containing irregular elastic fibers present in the grafted fascia.Cartilage grafts offer better ability to resist infection,pressure,and cope with insufficient vascular supply.This means that cartilage grafts are suitable for use in revision cases.

Clinical factors correlated with the success rate of miniscrews in orthodontic treatment

Miniscrews offer a reliable alternative for anchorage during orthodontic treatment,particularly for non-cooperative patients or periodontal patients with alveolar bone loss.The study aims at assessing the correlation of various clinical indicators with the success or failure of miniscrews used for anchorage during orthodontic treatment.Thirty-four consecutive patients with a cumulative total of 82 miniscrews implanted participated in the study.Generalized Estimating Equations were used to assess the correlation of various factors with success rates.The miniscrew was considered the unit of analysis clustered within site and within patient.The overall success rate of miniscrews was 90.2%.For every additional miniscrew used in a patient＇s oral cavity,the success rate was reduced by 67%.Retromandibular triangle and palatal placement and in movable mucosa resulted in lower success rate.The miniscrew length and diameter were found to correlate with success rates.Orthodontic force applied on miniscrews for uprighting purposes showed a lower success rate than that used for retraction.This study revealed that miniscrews present high success rates.The number of miniscrews used per patient,the miniscrew site placement,the soft tissue type of placement,the miniscrew length and diameter as well as the orthodontic force applied on the miniscrew showed significant correlation with success rates.

Comparison of Success Rate and Radiological Bone Loss in Patients with Mini-Implant versus Conventional-Sized Implant Removable Prostheses: A Meta-Analysis

Background: The objective of this meta-analysis was to assess whether mini-implants have added benefit in terms of implants success rate and average bone loss over conventional-sized implants after one year of follow-up. Methods: An electronic search of randomized clinical trials was conducted in MEDLINE (via PubMed), Cochrane Central Register of Clinical Trials (CENTRAL) and Web of Science for studies including complete or partial edentulous patients requiring two or four mini-implants or conventional/ standard-sized implants in the maxilla or mandible for implant-supported removable prostheses who completed 12 months of follow-up. Results: The search provided 194 unique articles which were screened for title and abstract. Screening generated 12 articles which went through full-text analysis using eligibility criteria, and 4 articles were included for meta-analysis. Meta-analysis of these studies indicated a non-significant difference in the success rate between the two interventions (OR = 1.69 [0.74, 3.85;p = 0.21]). Bone loss estimates resulted in a significant bone reduction (Mean Difference = -0.74 [-0.95, -0.53;p < 0.05]) in favor of two mini-implants when compared with two conventional-sized implants, but when compared four mini- with two conventional-sized implants, the estimates were non-significant (Mean Difference = -0.24 [-0.69, 0.20;p = 0.29]). Conclusion: The current evidence does not provide solid evidence of the benefits of one intervention over the other. More studies with follow-up times of 10 and more years are needed as current studies have described the short-term outcomes.

Accuracy Analysis of Assembly Success Rate with Monte Carlo Simulations

Monte Carlo simulation was applied to Assembly Success Rate (ASR) analyses.ASR of two peg-in-hole robot assemblies was used as an example by taking component parts' sizes,manufacturing tolerances and robot repeatability into account.A statistic arithmetic expression was proposed and deduced in this paper,which offers an alternative method of estimating the accuracy of ASR,without having to repeat the simulations.This statistic method also helps to choose a suitable sample size,if error reduction is desired.Monte Carlo simulation results demonstrated the feasibility of the method.

Treatment success rate of tuberculosis patients in Dabat, northwest Ethiopia

Evaluating the outcomes of DOTS program is essential for recognizing and amending system failures before the incidence and proportion of resistant isolates rise. In this study, we seek to evaluate the impact of DOTS strategy on tuberculosis treatment success rate in Dabat, northwest Ethiopia. Medical records of 1305 pulmonary and extrapulmonary tuberculosis patients registered from 2007 to 2012 at two health centers in Dabat district, northwest Ethiopia, were reviewed. Treatment outcomes and forms of tuberculosis were assessed according to WHO guidelines. Descriptive analyses were performed using frequencies and percentages. Treatment success rate was observed in 1146 (87.8%) patients. Out of these, 534 (89.1%) of the males and 612 (86.7%) of the females were successfully treated. It was also true in 338 (87.8%) of the smear-positive pulmonary tuberculosis patients, 473 (85.7%) of the smear-negative pulmonary tuberculosis patients, and 335 (91.0%) of the extrapulmonary tuberculosis patients. In conclusion, treatment success rate in the current study was slightly higher than the WHO international updated target for the period 2011 to 2015. However, this doesn’t mean that there will be no need for further enhancement of supervision and monitoring techniques, strengthening counseling and health education programs, and improving the quality of laboratory diagnostic services.

Optimal use of fielder XT guidewire enhances the success rate of chronic total occlusion percutaneous coronary intervention

BACKGROUND Chronic total occlusion(CTO) is found in 18-31% of patients who undergo coronary angiography. Successful recanalization of CTOs is associated with reduced recurrent angina pectoris rates and increased long-term survival.Although the success rate of CTO percutaneous coronary intervention(CTO-PCI)has improved, CTO-PCI remains technically challenging. The Fielder XT guidewire was designed for CTO lesions. To validate whether the use of the guidewire increases the success rate, we compared the results of CTO-PCI with or without the guidewire. We hypothesized that the use of Fielder XT guidewire can increase the success rate of CTO-PCI.AIM To investigate whether the use of Fielder XT guidewire increases the final procedural success of CTO-PCI via the anterograde approach.METHODS Between January 2013 and December 2015, a retrospective study was conducted on 1230 consecutive patients with CTO who received PCI via the anterograde approach at the General Hospital of Northern Theater Command. The patients were divided into an XT Group(n = 686) and a no-XT Group(n = 544) depending on whether Fielder XT guidewire was used. Both groups were compared for clinical parameters, lesion-related characteristics, procedural outcomes and inhospital complications. The data were statistically analyzed using Pearson's χ~2 test for categorical variables, and Students' t test was used to compare the quantitative data. Significant independent factors and a risk ratio with 95%confidence interval(CI) were assessed by multivariate logistic regression analysis.RESULTS In total, 1230 patients were recruited; 75.4% of the patients were male, and 55.8%of the patients were in the XT group. The overall success rate was 83.9%, with87.8% in the XT group. Based on multivariate logistic regression analysis, factors positively associated with procedural success were the use of Fielder XT guidewire(P = 0.005, 95%CI: 1.172-2.380) and systolic blood pressure(P = 0.011,95%CI: 1.003-1.022), while factors negatively associated with procedural success were blunt stump(P = 0.013, 95%CI: 1.341-11.862), male sex(P = 0.016, 95%CI:0.363-0.902), New York Heart Association(NYHA) class(P = 0.035, 95%CI: 0.553-0.979), contrast amount(P = 0.018, 95%CI: 0.983-0.998) and occlusion time(P =0.009, 95%CI: 0.994-0.999). No significant differences were found between the XT group and the no-XT group with respect to clinical parameters, lesion-related characteristics, coronary artery rupture [3(0.4%) vs 8(1.5%), P = 0.056], inhospital death [2(0.3%) vs 6(1.1%), P = 0.079] or in-hospital target lesion revascularization [3(0.4%) vs 7(1.3%), P < 0.099]. However, there were significant differences between the groups with respect to success rate [602(87.8%) vs 430(79.0%), P < 0.001], procedure time [(74 ± 23) vs(83 ± 21), P < 0.001], stent length[(32.0 ± 15.8) vs(37.3 ± 17.6), P < 0.001], contrast amount [(148 ± 46) vs(166 ± 43),P < 0.001], post-PCI myocardial infarction [43(6.3%) vs 59(10.8%), P = 0.004],major adverse cardiovascular event [44(6.4%) vs 57(10.7%), P = 0.007], side branch loss [31(4.5%) vs 44(8.1%), P = 0.009], contrast-induced nephropathy [29(4.2%) vs 40(7.4%), P = 0.018] and no reflow [8(1.2%) vs 14(2.9%), P = 0.034].CONCLUSION The use of Fielder XT guidewire shortens the Procedure and increases the success rate of CTO-PCI, and is also associated with reduced complication rates.

Evaluation of factors affecting the success rate of orthodontic mini-implants by survival analysis

AIM: To investigate the success rate of mini-implants and its characteristics and risk factors by survival analyses. METHODS: Three hundred and ninety-four miniimplants of the same type were placed by a single clinician. Age, gender, treatment duration, time of failure, side and jaw of implantation and the soft tissue at placement site were recorded. Odds ratio, survival curves, and Cox proportional hazard model were applied to evaluate the factors influencing the miniimplants' success rate. RESULTS: The cumulative success rate was 88.1%.The maxilla had a significantly higher success rate than that of the mandible(91.7% vs 83.7%, respectively, P = 0.019). Placement of mini-implants in the attached gingiva(AG) showed a higher success rate than that of the mucogingival junction(MGJ) and mucous membrane(MM)(AG, 94.3%; MGJ, 85.8%; MM, 79.4%; P < 0.001). Significant association was found between the jaw and the gingival tissue type(P < 0.001). There were no significant differences between maxilla and mandible when compared within each placement site.CONCLUSION: The gingival tissue type had the most significant effect on the success rate of the mini-implant with higher success rate in the attached gingiva.

From December 1987 to October 1983, percutaneous transluminal coronary angioplasty (PTCA) was performed in 302 patients with 392 diseased vessels and 440 lesions. The success rate was 93.71% in 302 patients, 94.90% in 392 diseased vessels and 95.00% in 440 lesions. The success rate was 98.92% in Type A lesion, 95.71% in Type B lesion, and 86.57% in Type C lesion (A vs B P=NS, A vs C P<0.01). There were 55 lesions with total or subtotal occlusion, the success rate was 89.09% (93.10% in Type B lesion and 84.62% in Type C lesion). As to the diseased vessels, the success rate was 95.65% in LAD, 94.38% in LCX and 93.75% in RCA. The results showed no significant difference. In this series, acute ischemic complications were found in 6.59% (29 / 440). Of these 29 lesions, 23 were treated successfully, 5 developed Q wave myocardial infarction and 1 died.

Gas Exchange Rates of Texas Persimmon (Diospyros texana) in Central Texas Woodlands

Diospyros texana (Texas persimmon) is a secondary species in most Juniperus ashei/Quercus fusiformis woodlands in central Texas. It has high density, but plants are mostly in the community understory. Light response curves at ambient and elevated levels of CO2 and temperature were measured for D. texana. The Anet (photosynthetic rate) increased significantly as both light level and CO2 levels increased but not temperature. The Amax (maximum photosynthetic rate) of D. texana in full sun at elevated levels of CO2 was increased for all treatments. Stomatal conductance increased with levels of CO2 but only if the interaction was removed from the model. Intercellular levels of CO2 increased with both temperature and CO2 treatments as did water use efficiency (WUE). Furthermore, light saturation (Lsat) increased with CO2 treatments and light compensation (Lcp) increased with temperature. The dark respiration (Rd) increased with both temperature and CO2 treatments. Markov population models suggested D. texana populations would remain ecologically similar in the future. However, sub-canopy light levels and herbivory should be considered when examining population projections. For example, Juniperus ashei juveniles are not recruited into any canopy unless there are high light levels. Herbivory reduces the success of Quercus juveniles from reaching the canopy. These factors do not seem to be a problem for D. texana juveniles which would allow them to reach the canopy without need of a high light gap and are not prevented by herbivory. Thus, Juniperus/Quercus woodlands will change in the future to woodlands with D. texana a more common species.

Success Rate Versus Finite Run Time in Local Adiabatic Quantum Search Algorithm

In adiabatic quantum algorithm, the success rate is approximately equal to 1 while the run time satisfies the adiabatic condition. But the relation between the short run time and success rate for adiabatic quantum algorithm is poorly understood. In this paper, we study the success rate of local adiabatic quantum search algorithm with an arbitrary finite run time(non-adiabatic evolution). By solving the time-independent Schr¨odinger equation, we obtain differential equations to calculate the success rate. The differential equations show that the success rate is closely related to the adiabatic parameter s(t). Utilize the differential equations, we give the function of success rate versus run time in local adiabatic search numerically. The result indirectly verifies that T ～ O(N^(1/2)) is optimal in local adiabatic search.
