Customized Titanium Lattice Structure in Three-Dimensional Alveolar Defect: An Initial Case Letter
2018
The aim of this initial case report was to provide a new protocol for the clinical application of a patient-specific titanium lattice structure (Yxoss CBR®, ReOSS, Filderstadt, Germany) for customized bone regeneration. To obtain a 3-dimensional reconstruction of a posterior mandible segment in a 61-year-old woman, a patient-specific titanium customized lattice structure was used. As graft material autogenous bone tissue mixed with xenogenic alloplastic material (Bio Oss®, Geistlich Pharma, Wolhusen, Switzerland) was obtained for reconstruction. After a healing period of 6 months, the titanium lattice structure was removed and implant placement (Camlog Screw Line, 3.8/11, Camlog, Wimsheim, …
Alpha-1 antitrypsin deficiency: outstanding questions and future directions
2018
BACKGROUND: Alpha-1 antitrypsin deficiency (AATD) is a rare hereditary condition that leads to decreased circulating alpha-1 antitrypsin (AAT) levels, significantly increasing the risk of serious lung and/or liver disease in children and adults, in which some aspects remain unresolved. METHODS: In this review, we summarise and update current knowledge on alpha-1 antitrypsin deficiency in order to identify and discuss areas of controversy and formulate questions that need further research. RESULTS: 1) AATD is a highly underdiagnosed condition. Over 120,000 European individuals are estimated to have severe AATD and more than 90% of them are underdiagnosed. CONCLUSIONS: 2) Several clinical and…
Étude de la biodégradation de l'herbicide acide 2.4-dichlorophénoxyacétique (2.4-D) dans des sols agricoles de la région de Constantine
2011
Les principaux facteurs conditionnant la biodégradation du 2,4-D dans trois sols agricoles algériens (45IB, 46BM et 47AA), notamment l'humidité et la température, ont été examinés. Les cinétiques de minéralisation de l'herbicide ont été déterminées par radiorespirométrie, qui consiste à piéger et estimer le 14C02 formé dans une solution de soude à l'aide d'un compteur à scintillation liquide. Les résultats obtenus confirment la présence de microorganismes dégradants le 2,4-D et la biodégradation de cet herbicide semble dépendre essentiellement des propriétés physicochimiques intrinsèques des sols notamment la teneur en argile et MgO. Le sol 46BM, caractérisé par de faibles quantités en sabl…

Urban drinking and driving:comparison of electric scooter and bicycle related accidents in facial fracture patients
2022
In recent years, electric scooters (e-scooter) have emerged as an alternative mode of urban transport due to their availability and effortless use. However, e-scooter-related trauma and injuries, especially to the head, have received wide media coverage and raised public concern about their safety. We aim to determine and compare clinically relevant variables, incidence, and severity between bicycle and e-scooter-related facial fractures and potential protective measures for injury prevention. This retrospective study comprised all patients admitted to a tertiary trauma center with bicycle or e-scooter-related facial fractures between January 2019 and October 2020. Patient- and injury-relat…
OPTIMIZING PREIMPLANTARY OFFER TROUGH PIEZOSURGERY TECHNIQUES
2016
Introduction. In most of the cases, duet o post-extractional atrophy the bone offer is insufficent for placing implants. Piezosurgery splitting techniques represent the modern and non-invasive alternative used for ridge remodeling, sinus lift and other surgical bone preservation maneuvres. Purpose. The purpose of this study is to present new surgical techniques that radically simplify maxillary sinus interventation, avoiding membrane perforation and new splitting tecniques in advanced bone and ridge atrophy. Material and method. In this study, sinus lifting was performed using piezo-elevation of the membrane and the pressure ogenerated by the saline solution. Out of 67 patients, 20 have had…
Relationship of choroidal thickness with pulsatile hemodynamics in essential hypertensive patients
2021
Controversy exists about the association of choroidal thickness (CTh) with blood pressure (BP) values. There is some evidence suggesting that central hemodynamics changes are associated with microvascular disease. Our study was aimed to assess the relationships between CTh and clinic and 24-h BP and between CTh and estimated 24-h aortic pulse pressure (aPP), 24-h aortic systolic BP (aSBP), and 24-h aortic augmentation index (aAIx) in a group of hypertensive patients. We enrolled 158 hypertensive subjects (mean age 48 ± 13 years) all of which underwent evaluation of the choroidal district by Swept-Source optical coherence tomography (SS-OCT) and 24-h BP monitoring, in order to measure periph…
CLINICAL STUDY OF TRANSVERSAL AUGMENTATION IN BONE DEFECTS OF THE MAXILLARY AESTETHIC AREA
2015
Scope: To outline the importance of autogenic bone graft addition for correcting bone defects in the frontal and lateral maxillary area, and for achieving outstanding esthetic results in cases of large bone defects. Materials and method: A total number of 478 argumentations has been performed in the implantology and dental clinic of the Emergency Military Hospital Sibiu between 2009 and 2013. Results and discussion: The transversal rehabilitation techniques of frontal maxillary ridges, representing 57.2% of all addressed cases, were the most frequent ones, justifying the fact that the frontal maxillary area, aesthetically sensitive, is of special attention for both patients and specialists.…
Convolutional Neural Network Based Sleep Stage Classification with Class Imbalance
2022
Accurate sleep stage classification is vital to assess sleep quality and diagnose sleep disorders. Numerous deep learning based models have been designed for accomplishing this labor automatically. However, the class imbalance problem existing in polysomnography (PSG) datasets has been barely investigated in previous studies, which is one of the most challenging obstacles for the real-world sleep staging application. To address this issue, this paper proposes novel methods with signal-driven and image-driven ways of noise addition to balance the imbalanced relationship in the training dataset samples. We evaluate the effectiveness of the proposed methods which are integrated into a convolut…
Diagnostic challenges and potential early indicators of breast periprosthetic anaplastic large cell lymphoma
2020
Abstract Rationale: Anaplastic large T-cell lymphoma (BI-ALCL) is a rare primitive lymphoma described in women with breast implant prostheses, which has been arousing interest in recent years due to its potentially high social impact. The difficult diagnosis associated with the high and increasing number of prosthetic implants worldwide has led to hypothesize an underestimation of the real impact of the disease among prosthesis-bearing women. The aim of this work is to search for specific radiological signs of disease linked to the chronic inflammatory pathogenetic mechanism. Patient concerns: This work describes a case of BI-ALCL in an American woman with no personal or family history of c…
