To compare the clinical success rate of Prefabricated Zirconia crowns and stainless steel crowns on primary molars: It is an in-vivo study which was performed on 52 pulpally treated primary molars of children aged 4–9 years were randomly divided into two equal groups of stainless steel crown and Prefabricated Zirconia crowns. Tooth preparation was done according to the manufacturer’s recommendations and crowns were cemented. All crowns were cemented with Type I Glass ionomer cement (GIC) luting cement. Crowns were evaluated clinically for its crown retention, marginal integrity and gingival health at 3 months and 6 months.: Clinical success for stainless steel crowns and Prefabricated Zirconia crowns towards crown retention and marginal integrity were similar with no statistical difference between them. All Prefabricated Zirconia crowns showed healthy gingiva whereas 53.8% (14 out of 26) Stainless Steel crowns showed mild gingival inflammation at 3 and 6 months which was statistically significant (P ≤0.01). Both prefabricated zirconia and stainless steel crowns showed no statistical difference for crown retention and marginal integrity throughout the study. Gingival health was significantly higher for Prefabricated Zirconia crowns compared with stainless steel crowns. Therefore clinical success rate for Prefabricated Zirconia crowns were better when compared to stainless steel crowns. So Prefabricated Zirconia crowns can be considered as an esthetic alternative in future.

A pre-procedural ultrasound of the lumbar spine is frequently used to facilitate neuraxial procedures. The aim of this review is to examine the evidence sustaining the utilization of pre-procedural neuraxial ultrasound compared to conventional methods. We perform a systematic review of randomized controlled trials with meta-analyses. We search the electronic databases Medline, Cochrane Central, Science Direct and Scopus up to 1 June 2019. We include trials comparing a pre-procedural lumbar spine ultrasound to a non-ultrasound-assisted method. The primary endpoints are technical failure rate, first-attempt success rate, number of needle redirections and procedure time. We retrieve 32 trials (3439 patients) comparing pre-procedural lumbar ultrasounds to palpations for neuraxial procedures in various clinical settings. Pre-procedural ultrasounds decrease the overall risk of technical failure (Risk Ratio (RR) 0.69 (99% CI, 0.43 to 1.10), p = 0.04) but not in obese and difficult spinal patients (RR 0.53, p = 0.06) and increase the first-attempt success rate (RR 1.5 (99% CI, 1.22 to 1.86), p < 0.0001, NNT = 5). In difficult spines and obese patients, the RR is 1.84 (99% CI, 1.44 to 2.3; p < 0.0001, NNT = 3). The number of needle redirections is lower with pre-procedural ultrasounds (SMD = −0.55 (99% CI, −0.81 to −0.29), p < 0.0001), as is the case in difficult spines and obese patients (SMD = −0.85 (99% CI, −1.08 to −0.61), p < 0.0001). No differences are observed in procedural times. Ιn conclusion, a pre-procedural ultrasound provides significant benefit in terms of technical failure, number of needle redirections and first attempt-success rate. Τhe effect of pre-procedural ultrasound scanning of the lumbar spine is more significant in a subgroup analysis of difficult spines and obese patients.

Abstract Aim This systematic review and meta-analysis aims to assess this relationship and determine the most appropriate age for recommendation of surgery. Method According to the “Preferred Reporting items for systematic review and meta-analysis” (PRISMA) statement, a literature search was performed across Medline, EMBASE and the Cochrane library from 1946-2018. Articles examining a relationship between age and myringoplasty or type 1 tympanoplasty success rates were screened. Results 20 articles encompassing data from 2244 procedures were included. The overall results conveyed a clear correlation between increasing age and rising success rate. A t-test was conducted which demonstrated a significant (P = 0.05) transition at aged 10, whereby success rate below age 10 was 70.6% and above 10 was 86%. Conclusions This systematic review and meta-analysis has uncovered a clear correlation between increasing age and increasing success rate for myringoplasty in the paediatric population. Furthermore, a significant transitional point has been demonstrated at the age of 10 and We hope that knowledge of increased success rates particularly after the age of 10 helps clinicians make more informed decisions about when to operate

Background: Superior vena cava (SVC) syndrome is caused by the occlusion of the SVC and can result in significant morbidity and mortality. Recently, endovascular therapy (ET) has become the standard of care for majority of these patients. We performed a systematic review of available literature to assess the contemporary technical success rate, restenosis rate, and recurrence rate of SVC syndrome following endovascular intervention. Methods: We searched PubMed, Cochrane Library, and Embase databases from 1988 to 2019 for studies on Endovascular Therapy for SVC syndrome. After screening 709 records, 13 studies were included. Screening was conducted using Rayyan QCRI software for systemic reviews. Studies included full-length journal articles on SVC syndrome and ET among adults (18+ years). Case reports, or case series with <20 patients were excluded. Data analysis was performed using OpenMeta software. Proportions and 95% confidence intervals (CIs) were calculated using random effects models. Heterogeneity among studies was assessed using Q and I 2 statistics. We evaluated the end-points of the technical success, restenosis rate and recurrence rates in SVC syndrome patients after endovascular stenting Results: A meta-analysis of 13 studies included a total of 1024 patients. The results of our meta-analysis show a weighted technical success rate of 98.6% (95% CI 0.97 – 0.99) (Fig. 1A), restenosis rate of 11.8% (95 CI 0.08-0.14) (Fig 1B) and recurrence rate of 9.9% (95% CI 0.06-0.13) (Fig 1C). Our studies had a substantial heterogeneity (I 2 ) of 52-80%. Figures:Figure 1A Figure 1B Figure 1C Conclusions: Our systematic review revealed high technical success rate, low restenosis, and recurrence rates after endovascular therapy supporting the paradigm of endovascular therapy as first line treatment for patients with SVC syndrome. Disclosures: Dr. Bashir has equity interest in Thrombolex Inc.
