Abstract Objective The purpose of the present prospective, case-series study was to report implant survival rate and marginal bone remodeling expected 5 years after loading using dental implants placed in daily practice. Materials and Methods This research was designed as an open-cohort, prospective, case-series evaluation. Any partially or completely edentulous patient, scheduled to receive at least one bone level implant, was considered eligible for this study. Primary outcome measurements were: implant and prosthetic cumulative survival rate and any complications experienced up to the 5-year follow-up. Secondary outcome measures were: thickness of gingival biotype, implant insertion torque, implant stability quotient, and marginal bone loss (MBL). Results Ninety consecutive patients (34 males and 56 females, aged between 24 and 81 years old [mean: 53.2 ± 15.4]) with 243 inserted implants were followed for at least 5 years after loading (mean: 65.4 ± 3.1 months; range from 60 to 72). At the 1-year follow-up, no drop-outs were recorded, but 17 patients (18.9%) with 18 restorations (12.6%) delivered on 34 implants (14%) were lost at the 5-year examination. At the 5-year follow-up examination, six implants lost osseointegration (97.5%). In the same period, four prostheses failed (97.2%). Five complications were reported in five different patients (prosthetic success rate was 96.5%, at patient level). Five years after loading, the mean MBL was 0.41 ± 0.30 mm. The difference from the 1-year data was 0.04 ± 0.19 mm. A statistically significant higher MBL was found for smokers, and patients with thin gingival biotype. The mean implant insertion torque was 42.9 ± 4.8 Ncm (range from 15 to 45 Ncm). Two-hundred and three implants (83.5%) were inserted with an insertion torque ≥35 and ≤45 Ncm. Conclusions High implant survival and success rate could be expected with stable marginal bone remodeling up to 5 years after loading. Smoking and thin tissue biotype were the most important variabilities associated with higher MBL. Further research studies are needed to confirm these results.

Background: Cardiovascular disease is a major cause of morbidity and mortality in patients with end-stage kidney disease. Arterio-venous fistulas (AVF), the gold standard for hemodialysis vascular access, are known to alter cardiac morphology and circulatory hemodynamics. We present a prospective case series of patients after creation of an AVF, explore the timeline for changes in their cardiac morphology, and detail considerations for clinicians. Methods: Patients were recruited in 2010 at multiple centers immediately prior to the creation of an upper-arm AVF and the initiation of hemodialysis. Cardiovascular magnetic resonance images were taken at intake before the creation of the AVF, 6-month follow-up, and 12-month follow-up. Image segmentation was used to measure left ventricular volume and mass, left atrial volume, and ejection fraction. Results: Eight patients met eligibility criteria. All eight patients had a net increase in left ventricular mass over enrollment, with a mean increase of 9.16 g (+2.96 to +42.66 g). Five participants had a net decrease in ejection fraction, with a mean change in ejection fraction of −5.4% (−21% to +5%). Upon visual inspection the patients with the largest ejection fraction decrease had noticeably hypertrophic and dilated ventricles. Left atrial volume change was varied, decreasing in five participants, while increasing in three participants. Changes in morphology were present at 6-month follow-up, even in patients who did not maintain AVF patency for the entirety of the 6-month period. Conclusion: All patients included in this prospective case series had increases in left ventricular mass, with variability in the effects on the ejection fraction and left atrial volume. As left ventricular mass is an independent predictor of morbidity and mortality, further research to determine appropriate vascular access management in both end-stage kidney disease and kidney transplant populations is warranted.

Abstract Purpose To present the outcome of optic disc pit maculopathy (ODPM) managed successfully with inverted internal limiting membrane (ILM) flap over the optic disc. Methods This prospective case series included three patients with ODPM who underwent pars plana vitrectomy with posterior vitreous detachment induction, followed by inverted ILM flap over the optic disc and gas tamponade. Patients were followed for 7-16 weeks as regards their functional and anatomical findings. A narrative review is also provided about Pathology, Pathogenesis, and surgical techniques in the treatment of ODPM Results Three adult patients (25–39 years old) were evaluated, with a mean duration of decreased visual acuity of 7.33 ± 2.40 months (4-12 months). Postoperatively, BCVA improved dramatically in one patient from 2/200 to 20/25. BCVA in the other two improved two and three lines, to 20/50 and 20/30, respectively. Significant anatomic improvement was achieved in all patients. Conclusion Vitrectomy with inverted ILM flap insertion over the optic disc can yield favorable anatomical improvement in patients with ODPM.

Background: Venous leg ulcers severely affect patients’ quality of life due to its high morbidity and recurrent nature. Currently, compression therapy is the first-line treatment for venous leg ulcers. Aim: This study sought to evaluate the efficacy of the Mobiderm® technology developed by Thuasne in a prospective case series of venous leg ulcers. Methods: Nine patients ( N  =  9) with venous leg ulcers were enrolled into this case series. Mobiderm® bandage was applied on to the affected limbs of the patients in the multi-component bandages system. The bandages were changed as frequent as the patients had their wound dressing for their standard treatment in a 12-week duration. Wound size and calf circumference were measured at week 0 and week 12. Paired sample t-test was used to compare the mean values of wound size and calf circumference pre- and post-treatment. Results: Reductions in wound size and calf circumference were observed in all nine patients (100%). Five patients were evaluable at week 12. The wound sizes significantly reduced by 27.2% to 53.2% ( p  =  0.02), and the calf circumferences significantly reduced by 3.2% to 26.0% ( p  =  0.02) after 12 weeks ( N  =  5). Safety was unremarkable, with no occurrence of treatment-emergent-related adverse event. Conclusion: Mobiderm® bandage was reported to be effective in promoting wound healing and reducing swelling, suggesting it to be integrated in the compression therapy for the management of venous leg ulcers.
