[Ab] Abstract:BACKGROUND: We describe the fabrication and performance of a chronic in situ coil system designed to allow focal brain stimulation in rats while acquiring functional MRI data. NEW METHOD: An implantable receive-only surface radiofrequency coil (iCoil) was designed to be fitted subcutaneously, directly onto to the rat skull surface during the intracerebral cannulation procedure. The coil is fixed in place using acrylic dental cement anchored to four screws threaded into the skull. To demonstrate the use of this coil system in situ, whole-brain functional MRI scans were acquired during various stimuli, including intracranial microinfusions of bicuculline and morphine in the prefrontal cortex and ventral tegmental area, respectively. RESULTS/COMPARISON TO OTHER METHODS: SNR performance of the iCoil was superior to three commercially-available coils, in some instances by a factor of two. Widespread BOLD activation was observed in response to bicuculline and morphine microinfusions. CONCLUSION: A new approach was demonstrated for high-SNR MR imaging of the brain in rats with intracranial implants using an implantable surface coil. This approach enables mapping the functional response to highly targeted stimuli such as intracranial microinfusions.

[Ab] Abstract:OBJECTIVES/HYPOTHESIS: To develop a prediction model that can accurately predict the chance of success following revision stapes surgery in patients with recurrent or persistent otosclerosis at 2- to 6-months follow-up and to validate this model internally. STUDY DESIGN: A retrospective cohort study of prospectively gathered data in a tertiary referral center. METHODS: The associations of 11 prognostic factors with treatment success were tested in 705 cases using multivariable logistic regression analysis with backward selection. Success was defined as a mean air-bone gap closure to 10 dB or less. The most relevant predictors were used to derive a clinical prediction rule to determine the probability of success. Internal validation by means of bootstrapping was performed. Model performance indices, including the Hosmer-Lemeshow test, the area under the receiver operating characteristics curve (AUC), and the explained variance were calculated. RESULTS: Success was achieved in 57.7% of cases at 2- to 6-months follow-up. Certain previous surgical techniques, primary causes of failure leading up to revision stapes surgery, and positions of the prosthesis placed during revision surgery were associated with higher success percentages. The clinical prediction rule performed moderately well in the original dataset (Hosmer-Lemeshow P = .78; AUC = 0.73; explained variance = 22%), which slightly decreased following internal validation by means of bootstrapping (AUC = 0.69; explained variance = 13%). CONCLUSIONS: Our study established the importance of previous surgical technique, primary cause of failure, and type of the prosthesis placed during the revision surgery in predicting the probability of success following stapes surgery at 2- to 6-months follow-up.

[Ab] Abstract:The present study aimed to evaluate the microtensile bond strength (µTBS) of novel computer-aided design/computer-aided manufacturing (CAD/CAM) restorative materials to dentin using different adhesive strategies. Thirty-two crowns were milled using CAD/CAM materials (Vita Mark II as control, Vita Suprinity, Vita Enamic and Lava Ultimate) and luted to dentin using different resin cements (RelyX ARC, RelyX Unicem 2 and RelyX Ultimate). The specimens were stored in 100% relative humidity at 37°C for 24 h and sectioned. The samples (n = 16) with cross-sectional areas of approximately 0.90 mm2, were submitted to a µTBS test in a universal testing machine with a crosshead speed of 0.5 mm/min. The samples were analyzed with SEM to determinate the failure mode. According to 2-way ANOVA and Tukey's test (α=0.05), the interaction effect (material x luting strategy) was significant (p=0.001). Regardless of the luting strategy, a higher µTBS was obtained with Lava Ultimate and Vita Enamic, which were significantly different from Vita Mark II and Vita Suprinity (p<0.05). For Vita Mark II, Vita Suprinity, Vita Enamic, and Lava Ultimate, the µTBS obtained with RelyX Unicem 2 was not significantly different from that obtained with RelyX ARC or RelyX Ultimate. All groups obtained at least three types of failure. The adhesive strategy with self-adhesive resin cement was comparable to conventional resin cement with total-etch or self-etch adhesive techniques in the bond of novel CAD/CAM materials to dentin.

[Ab] Abstract:With the overwhelming acceptance of lithium disilicate and zirconia, the frequency with which dentists have to remove these materials is increasing, and this can be difficult. Proper cement usage for full-coverage crowns with preparations that have retention and resistance can be helpful if in the future the restoration needs to be removed. When removing these modern materials, bur and laser techniques are both effective means, with each having specific benefits. Materials selection and preparation design are vital when considering areas of risk each patient exhibits and the potential need for removal.

[Ti] Title:Surgical repair of atrioventricular septal defects: incidence and mode of failure of the left atrioventricular valve.

[Is] ISSN:1569-9285

[La] Language:eng
[Ab] Abstract:OBJECTIVES: Our goal was to investigate the outcome of the left atrioventricular valve (LAVV) after repair of atrioventricular septal defects (AVSDs) by analysing the mechanisms of LAVV failure. METHODS: A retrospective investigation of 202 children with AVSD, operated on between 1992 and 2016, was performed. Analysis focused on freedom from reoperation for LAVV dysfunction, with specific attention to the modes of failure. RESULTS: The population consisted of 129 (64%) patients with complete AVSD (cAVSD) and 73 (36%) patients with partial AVSD (pAVSD), corrected at a median age of 3.9 (interquartile range 3.4) months and 29.0 (interquartile range 90.4) months, respectively. Within a median follow-up period of 5.9 (interquartile range 12.6) years, 27 (13.4%) patients required reoperation for LAVV failure, respectively, in 17 (13.2%) patients with cAVSD and 10 (13.9%) patients with pAVSD. Freedom from reoperation for LAVV at 10 years was 87 ± 4% for cAVSD and 87 ± 5% for pAVSD (P = 0.789). The failure mode was predominantly technical in cAVSD (71% vs 20% in pAVSD), whereas residual anatomical anomalies entailed more frequently LAVV regurgitation (LAVVR) in pAVSD (80% vs 29% in cAVSD) (P = 0.018). Cleft suture dehiscence (n = 8) and incomplete cleft closure (n = 6) were considered technical failures, whereas remnant distortions of the subvalvular apparatus (n = 9), small asymmetric bridging leaflet (n = 2), double orifice (n = 1) and additional cleft (n = 1) were considered anatomical lesions. The incidence of repair at the 1st reoperation was 92.6%. Eight patients needed a 2nd and 2 patients a 3rd repeat LAVV operation. Five patients finally ended with a mechanical prosthesis. CONCLUSIONS: In the long term, patients with AVSD are still subject to LAVV failure. Despite systematic cleft closure, patients with cAVSD develop LAVV failure mainly because of a recurrent/residual deficit at the cleft, amenable to technical improvement. Patients with pAVSD need increased attention for additional anatomical features of the LAVV at the time of primary repair.

[Ab] Abstract:This study aimed to evaluate the in situ degree of conversion, contact angle, and immediate and long-term bond strengths of a commercial primer and an experimental adhesive containing indomethacin- and triclosan-loaded nanocapsules (NCs). The indomethacin- and triclosan-loaded NCs, which promote anti-inflammatory and antibacterial effects through controlled release, were incorporated into the primer at a concentration of 2% and in the adhesive at concentrations of 1, 2, 5, and 10%. The in situ degree of conversion (DC, n=3) was evaluated by micro-Raman spectroscopy. The contact angle of the primer and adhesive on the dentin surface (n = 3) was determined by an optical tensiometer. For the microtensile bond strength µTBS test (12 teeth per group), stick-shaped specimens were tested under tensile stress immediately after preparation and after storage in water for 1 year. The data were analyzed using two-way ANOVA, three-way ANOVA and Tukey's post hoc tests with α=0.05. The use of the NC-loaded adhesive resulted in a higher in situ degree of conversion. The DC values varied from 75.07 ± 8.83% to 96.18 ± 0.87%. The use of NCs in only the adhesive up to a concentration of 5% had no influence on the bond strength. The contact angle of the primer remained the same with and without NCs. The use of both the primer and adhesive with NCs (for all concentrations) resulted in a higher contact angle of the adhesive. The longitudinal µTBS was inversely proportional to the concentration of NCs in the adhesive system, exhibiting decreasing values for the groups with primer containing NCs and adhesives with increasing concentrations of NCs. Adhesives containing up to 5% of nanocapsules and primer with no NCs maintained the in situ degree of conversion, contact angle, and immediate and long-term bond strengths. Therefore, the NC-loaded adhesive can be an alternative method for combining the bond performance and therapeutic effects. The use of an adhesive with up to 5% nanocapsules containing indomethacin and triclosan and a primer with no nanocapsules maintained the long-term bond performance.

[Ab] Abstract:Objectives: Bioprosthetic aortic heart valves are increasingly implanted in younger patients. Therefore, a strategy for potential valve failure should be developed before implanting the 'first valve'. The goal of this in vitro study was to provide insight into the effects of the design of a bioprosthesis on a valve-in-valve implanted Sapien XT valve. Methods: The hydrodynamic performance of a 23-mm Sapien XT valve implanted in Vascutek Aspire, Edwards Perimount, Medtronic Mosaic and St. Jude Medical Trifecta heart valves was investigated in a left heart simulator. In addition to the hydrodynamic results, the leaflet dynamics were analysed in high-speed video recordings of the tests. Results: All valve-in-valve combinations in this study fulfilled the minimum acceptance criteria defined by relevant approval standards (e.g. ISO 5840) but displayed significant differences in their performances. Small inner diameters of the bioprostheses were associated with increased mean pressure gradients, decreased effective orifice areas and geometric opening areas as well as with pin-wheeling and uneven leaflet motion. In addition, implantation in bioprostheses with internally mounted leaflets was associated with lower paravalvular leakage. Conclusions: The results of this study suggest that a surgical bioprosthesis with a large inner diameter and internally mounted leaflets improves the heamodynamics and potentially the durability of a valve-in-valve combination. These results should give the attending physicians critical information to consider when deciding on a bioprosthesis for younger patients.

[Ab] Abstract:BACKGROUND: We report the successful use of allograft-prosthesis composite (APC) and structural femoral head allografting in the bilateral reconstruction of large femoral and tibial uncontained defects during revision total knee arthroplasty (RTKA). CASE PRESENTATION: A 67-year-old female with degenerative arthritis underwent bilateral total knee arthroplasty (TKA) using the Press Fit Condylar (PFC) modular knee system at our clinic in March, 1996. At 8 years postoperatively, the patient presented with painful, bilateral varus knees, with swelling, limited passive range of motion (ROM), and severe instability. We treated to reconstruct both knee using a femoral head allograft at the tibial site, a structural distal femoral allograft at the femoral site, and a varus-valgus constrained (VVC) prosthesis with cement. At the 10-year follow up, we found no infection, graft failure, loosening of implants, in spite of using massive bilateral structural femoral head allografts in RTKA. CONCLUSION: The use of APC enabled a stable and durable reconstruction in this uncommon presentation with large femoral bone deficiencies encountered during a RTKA.

[Ti] Title:Use of the Perceval Sutureless Valve in Active Prosthetic Aortic Valve Endocarditis.

[Cp] Country of publication:Netherlands
[La] Language:eng
[Ab] Abstract:BACKGROUND: Surgical treatment of active prosthetic aortic valve endocarditis presents a challenge for cardiac surgeons because of tissue friability and destruction caused by infection. Sutureless prostheses, such as the Perceval S (LivaNova, Saluggia, Italy), have emerged as an option among the different surgical approaches for these complicated cases. METHODS: This study presents data from 9 patients who underwent aortic valve re-replacement with the Perceval S because of active prosthetic aortic valve endocarditis between January 2014 and August 2016. Hemodynamic performance (mean transprosthetic gradient and type of aortic regurgitation) was assessed intraoperatively after weaning from cardiopulmonary bypass, at discharge, and to 6 months postoperatively. RESULTS: After weaning from cardiopulmonary bypass, cases 1 and 3 through 6 had no or trivial aortic regurgitation, cases 7 and 8 presented with trivial to mild regurgitation, case 9 showed mild intraprosthetic regurgitation, and case 2 had mild periprosthetic regurgitation. Cases 4 and 7 died of septic shock and multiorgan failure in the perioperative period. In the remaining patients, severity of aortic regurgitation maintained practically invariable at discharge compared with intraoperative results. These 7 patients did well at 6-month follow-up, with good clinical and hemodynamic performance of the Perceval S prosthesis. The median of mean transprosthetic gradient was 11 mm Hg (interquartile range: 10 to 12 mm Hg). Only patient 2 showed mild periprosthetic regurgitation; patient 9 showed mild intraprosthetic insufficiency, and the remaining patients had no or trivial regurgitation. CONCLUSIONS: The sutureless Perceval S valve is a reasonable alternative for surgical treatment of prosthetic aortic valve endocarditis.

[Ab] Abstract:BACKGROUND: To report a case of impending extrusion of Ex-PRESS shunt treated by shunt-position adjustment. CASE PRESENTATION: A 56-year-old Asian woman presented with impending extrusion and malposition of Ex-PRESS shunt in her left eye. The bleb of the left eye was shallow and diffuse. In the past, the patient was treated by Ex-PRESS shunt implantation under the scleral flap in both eyes. There had been no Ex-PRESS shunt-related complication in her right eye, and she reported no history of left-eye trauma. Based on these findings, we hypothesized that the source of the left-eye problem was a loosely fixed Ex-PRESS shunt spur. It was thought, furthermore, that this inadequate scleral resistance during the Ex-PRESS shunt implantation was due to the low scleral rigidity resulting from high myopia and insufficient maintenance of the anterior chamber. We proceeded to make an incision in the area adjacent to the Ex-PRESS shunt using a super sharp blade. The shunt was then pushed into the anterior chamber with forceps, and the spur was fixed firmly. Pushing the shunt to the anterior chamber was found to have been sufficient to fix it firmly. In fact, when the sclera was palpated with a sponge, aqueous outflow was observed with no shunt displacement. Postoperative intraocular pressure (IOP) was managed well, and the bleb had formed with diffuse, prominent shapes. The Ex-PRESS shunt was well sustained with good positioning. CONCLUSIONS: When an Ex-PRESS shunt operation is performed on a patient who shows a tendency for low scleral rigidity, shunt implantation should be accomplished carefully and with force adequate for firm spur fixation.
