Endometrial receptivity: evaluation with ultrasound.
2013
An adequate endometrial receptivity is a crucial factor for embryo implantation. We describe endometrial morphology (endometrial appearance or pattern, endometrial thickness, volume, and delimitation), based on the concepts and possibilities of the new ultrasound modalities (3-dimensional/4-dimensional ultrasound, automatic volume calculation, virtual organ computer-aided analysis, tomographic ultrasound image, inverse mode, and 3-dimensional Doppler angiography) as markers of endometrial receptivity.
ICD Implantation in Noncompaction of the Left Ventricular Myocardium: A Case Report
2009
Isolated noncompaction of the ventricular myocardium (INVM) is an uncommon cardiomyopathy characterized by the persistence of fetal myocardium with prominent trabecular meshwork and deep intertrabecular recesses, often associated with systolic dysfunction and ventricular dilatation. A 23-year-old man from Burkina Faso was referred to our operative unit with a diagnosis of INVM, made with echocardiogram and magnetic resonance imaging and nonsustained ventricular tachycardia. The literature reports the incidence of malignant ventricular arrhythmias in as many as 47% of the patients and sudden cardiac death in almost 50% of them and this supported our decision to perform implantable cardiovert…
Klassifikation und Therapie von Endolecks nach endovaskulärer Behandlung von abdominellen Aortenaneurysmen
2005
This article describes the classification of endoleaks after endovascular treatment of abdominal aortic aneurysms, thereby summarizing the most important problems of this endovascular technique. The correct classification of endoleaks is a prerequisite for interdisciplinary discussion. It is indispensable for professional reporting of the pathological findings and for the decision making as to the adequate treatment of endoleaks. Irrespective of the types of stent graft and property of the material, five endoleak types are defined in the literature: leakage at the anchor sites (type I); leakage due to collateral arteries (type II); defective stent grafts (type III); leakage due to porosity …
“Unlucky punch”: unexpected annular rupture during TAVR and successful treatment
2021
Although rare, annular rupture in TAVR is a feared and often unpredictable complication with relevant impact on in-hospital prognosis. Severe annular calcification is a common risk factor for annular rupture. We report on a case of annular rupture during TAVR with a balloon-expanded prosthesis in the absence of any annular calcification in the planning CT scan and illustrate the proposed pathomechanism as well as its successful immediate surgical management.
Embryologic outcome and secretome profile of implanted blastocysts obtained after coculture in human endometrial epithelial cells versus the sequenti…
2008
Objective To compare embryologic and clinical outcomes in terms of preimplantation development, implantation, pregnancy rates, and secretome profile of implanted blastocysts from the preimplantation genetic diagnosis program grown in sequential versus endometrial epithelial cell (EEC) coculture system. Design Retrospective clinical study and prospective experimental study. Setting In vitro fertilization clinical unit and university research laboratory. Intervention(s) Blastomere biopsy, embryo culture, blastocyst transfer, and protein analysis of the media conditioned from implanted embryos obtained from coculture and sequential systems. Main Outcome Measure(s) Clinical study: blastocyst, i…
Assessment of clinical outcomes and histomorphometric findings in alveolar ridge augmentation procedures with allogeneic bone block grafts: A systema…
2020
Background This systematic literature review aimed to evaluate the efficacy of allogeneic bone blocks for ridge augmentation by assessing block survival rates and subsequent implant survival, including post-surgical complications and histomorphometric analysis. Material and Methods An electronic and manual search among references, was conducted up to April 2019 by two independent authors. Inclusion criteria were: human clinical trials in which the outcomes of allogeneic bone block grafts were evaluated by means of their survival rates and subsequent implant success rates. Results Seven articles fulfilled the inclusion criteria and were analyzed. A total of 323 allogeneic block grafts were m…
An International, Multicenter Retrospective Observational Study to Assess Technical Success and Clinical Outcomes of Patients Treated with an Endovas…
2022
Introduction: Type III endoleaks post-endovascular aortic aneurysm repair (EVAR) warrant treatment because they increase pressure within the aneurysm sac leading to increased rupture risk. The treatment may be difficult with regular endovascular devices. Endovascular aneurysm sealing (EVAS) might provide a treatment option for type III endoleaks, especially if located near the flow divider. This study aims to analyze clinical outcomes of EVAS for type III endoleaks after EVAR. Methods: This is an international, retrospective, observational cohort study including data from 8 European institutions. Results: A total of 20 patients were identified of which 80% had a type IIIb endoleak and the r…
Comparison Between Simulated and Actual Unilateral Hearing in Sequentially Implanted Cochlear Implant Users, a Cohort Study
2019
Introduction: Previous studies have proven the effectiveness of bilateral cochlear implantation compared to unilateral cochlear implantation. In many of these studies the unilateral hearing situation was simulated by switching off one of the cochlear implants in bilateral cochlear implant users. In the current study we assess the accuracy of this test method. Does simulated unilateral hearing (switching off one cochlear implant) result in the same outcomes as real life unilateral hearing with one cochlear implant and a non-implanted contralateral ear? Study design: We assessed the outcomes of one arm of a multicenter randomized controlled trial. Methods: In the original trial, 38 postlingua…
Influence of the prosthetic arm length (palatal position) of zygomatic implants upon patient satisfaction
2016
Background: To assess the influence of the prosthetic arm length (palatal position) of zygomatic implants upon patient comfort and stability, speech, functionality and overall satisfaction. Material and Methods: A retrospective clinical study was made of patients subjected to rehabilitation of atrophic maxilla with complete maxillary implant-supported fixed prostheses involving a minimum of two zygomatic implants (one on each side) in conjunction with premaxillary implants, and with 12 months of follow-up after implant loading. Subjects used a VAS to score general satisfaction, comfort and stability, speech and functionality, and the results were analyzed in relation to the prosthetic arm l…
Effect of Rotary Instrument Mineral Oil Lubricant on Osseointegration: A Randomized, Blinded Study in Rabbits
2019
The mechanisms of early failures in dental implant osseointegration are unclear. A possible cause of low levels of bone formation is lubricant contamination on implants during insertion. To explore the impact of lubricant contamination on dental implants, we used 5 New Zealand rabbits and inserted 2 implants per tibia in each animal for a total of 4 implants per animal (20 implants in total). In general, bicorticalization was achieved. The first implant was placed as suggested by the manufacturer with no lubricant used (control). The second implant was placed using a freshly lubricated contra-angle handpiece, which was used only for the test implants. Implant allocation was randomized, and …
