alexandrossfakianakis shared this article with you from Inoreader A comparative study of three-dimensional airway changes after fibula flap reconstruction for benign and malignant tumours in the anterior mandible via International Journal of Oral and Maxillofacial Surgery via MedWorm.com Surgical treatment of tumours in the anterior mandible and surrounding tissues may result in defects which can be restored by a fibula free flap. The upper airway may change during this process. The purpose of this retrospective study was to evaluate upper airway changes after fibula free flap reconstruction. A total of 37 patients who underwent anterior mandibulectomy and fibula free flap reconstruction between 2012 and 2020 were recruited. Patients with benign and malignant tumours involving the anterior mandible were included. (Source: International Journal of Oral and Maxillofacial Surgery) View on Web

Individual “alveolar phenotype” limits dimensions of lateral bone augmentation

alexandrossfakianakis shared this article with you from Inoreader Individual "alveolar phenotype" limits dimensions of lateral bone augmentation via Journal of Clinical Periodontology Abstract Aim Alveolar ridge resorption following tooth extraction often renders a lateral bone augmentation inevitable. Some patients, however, suffer from severe early (during graft healing, Eres) and/or late (during follow-up, Lres) graft resorption. This study explored the hypothesis that the "individual phenotypic dimensions" may partially explains the degree of such resorptions. Material & methods Patients who underwent a guided bone regeneration (GBR) were screened for inclusion according to the following criteria: (1) a relatively symmetrical maxillary arch, (2) an intact contra-lateral alveolar bone dimension, (3) the presence of a pre-operative cone-beam CT (CBCT), (4) a CBCT taken immediately after GBR, and (5) at least one CBCT scan ≥6 months after surgery. CBCT scans from different timepoints were registered and imported into Mimics software (Materialise, Leuven, Belgium). Bone dimensions of the contra-lateral site of the augmentation, representing the "individual phenotypical dimension of the alveolar crest" (IPD) were super-imposed on the augmented site and registered accordingly. As such, Eres and Lres could be measured over time, in relation to the IPD (in 2D; per millimetre apically from the alveolar crest, in the centre of the GBR), as well as in 3D (the entire GBR, 2 mm away from the mesial, distal, and apical border for standardisation). Results A total of 17 patients (23 augmented sites) were included. After Eres, the outline of the augmentation was in general located ±1 mm outside the IPD, but ≥1,5 years after GBR, it further moved towards the IPD (85% within 0.5 mm distance). Conclusions Within the limitations of this study the results indicate that the dimensions of a lateral bone augmentation are defined by the "individual phenotypic bone boundaries" of the patient.

Clinical reproducibility of different centric relation recording techniques in edentulous individuals: an observational cross sectional study

alexandrossfakianakis shared this article with you from Inoreader Clinical reproducibility of different centric relation recording techniques in edentulous individuals: an observational cross sectional study via Journal of Prosthodontics Abstract Purpose To assess the reproducibility of four different centric relation (CR) recording techniques, and time spent performing each technique in edentulous individuals. Materials and Methods Four techniques were assessed: extraoral gothic arch tracing (EOGA), intraoral gothic arch tracing (IOGA), deglutition (D), and frontal manipulation with tongue elevation (FMTE). Twelve subjects participated in the study; four technique records were performed on each volunteer by the same operator. Each record was repeated three times, in the same period of the day, with a 30 min interval between each technique. The reproducibility of each technique was assessed by the tri-dimensional displacement of the position of the condylar housing (mandible condyle) to the wall of the condylar guide (glenoid cavity) in the semi-adjustable articulator (anteroposterior, mediolateral, and superior-inferior). The time spent on each technique was timed in seconds (from the beginning of each technique until the wax occlusion fixation). The analysis of variance and the Tukey test were performed for anteroposterior displacement (two-way) and for time spent on CT recording techniques (one-way) (α &l t; 0.05). Regarding mediolateral and superior-inferior displacements, the non-parametric Kruskal-Wallis was performed for the comparison between recording methods, while the Mann-Whitney test was performed for the comparison between sides (α < 0.05). Results The factor recording technique interfered with the anteroposterior displacement (ANOVA: α < 0.001; F = 11.396). The technique D (right side: 3.78 ± 0.69 mm; left side: 3.45 ± 0.74 mm) showed a statistically significant difference compared to the other techniques (EOGA: right side: 3.00 ± 0.00 mm; left side: 3.00 ± 0.00 mm; FMTE: right side: 2.81 ± 0.52 mm; left side: 2.82 ± 0.79 mm; IOGA: right side: 2.90 ± 0.65 mm; left side: 3.12 ± 0.44 mm). The time spent on the recording technique influenced the results (ANOVA: α < 0.001; F = 21.118). The IOGA (340.40 ± 163.41 seconds) and EOGA (285.93 ± 133.84 seconds) required more time compared to the D (86.00 ± 34.33 seconds) and FMTE (101.33 ± 36.72 seconds) techniques. Conclusion Graphic recordings showed better reproducibility and accuracy of the position of the centric relation. This article is protected by copyright. All rights reserved View on Web

Esthetic and clinical outcomes after immediate placement and restoration: Comparison of two implant systems in the anterior maxilla—A cross‐sectional study

alexandrossfakianakis shared this article with you from Inoreader Esthetic and clinical outcomes after immediate placement and restoration: Comparison of two implant systems in the anterior maxilla—A cross‐sectional study via Clinical Implant Dentistry and Related Research Abstract Aim To assess the esthetic and clinical performance of a novel self-tapping implant system for single-tooth restorations in the esthetic zone after immediate placement and provisionalization. Materials and Methods This cross-sectional study included 52 patients contributing a total of 52 immediately placed and restored implants with ≥12 months after functional loading, comparing two different implant systems: Straumann® BLX (Institut Straumann AG, Basel, Switzerland; 25 patients) and Ankylos® (Dentsply Sirona, Hanau, Germany; 27 patients). As the primary outcome measure, peri-implant tissue esthetics were assessed by means of pink esthetics score (PES) rated by three independent clinicians. Moreover, as secondary outcome measures, the peri-implant tissue health was assessed by means of bleeding on probing, probing depth, and suppuration. Apart from that, the modified plaque index, keratinized mucosa width, and the presence of mucosal recessions were also assessed. When clinical signs suggested the possibility of peri-implantitis, radiographs were indicated to assess progressive bone loss. Results The mean PES ratings were 12.10 ± 1.10 for Ankylos versus 11.2 ± 1.86 for BLX, both achieving good esthetic results without significant differences (p = 0.143). There were no differences among most clinical parameters (plaque, bleeding on probing, probing depth, peri-implant mucosal recession), although peri-implant mucositis was present in one-third of the cases. The inter-rater agreement on esthetics was not significant (p < 0.250). Conclusion Within the limitations of the present study, it was concluded that the use of either BLX or Ankylos implant systems was associated to comparable peri-implant health and good pink esthetic outcomes during immediate implantation and restoration protocols, for at least 12 months.

Coronavirus disease 2019 rebounds following nirmatrelvir/ritonavir treatment

alexandrossfakianakis shared this article with you from Inoreader Coronavirus disease 2019 rebounds following nirmatrelvir/ritonavir treatment via Journal of Medical Virology Abstract Nirmatrelvir/ritonavir (NMV-r) is an effective anti-SARS-CoV-2 agent and has been recommended in the treatment of non-hospitalized patients with COVID-19. In rare occasions, some patients experience virologic and symptomatic rebound after initial resolution, which we call COVID-19 rebound after NMV-r. Although COVID rebound can also occur after molnupiravir treatment or even no antiviral treatment, we have more serious concern about the rebound after NMV-r, which remains the most effective antiviral. Due to a lack of information about its frequency, mechanism, outcomes, and management, we conducted this review to provide comprehensive and updated information to address these questions. Based on the limited evidence, the incidence of COVID-19 rebound after NMV-r was less than 2%, and most cases developed 5–15 days after initiating NMV-r treatment. Almost all reported cases had mild symptoms, and the clinical condition gradually subsided without additional treatment. Overall, the clinical outcome was favourable, and only a small number of patients required emergency department visits or hospitalization. Regarding virologic rebound, culturable SARS-CoV-2 with possible transmission was observed, so re-isolation may be needed. This article is protected by copyright. All rights reserved. View on Web

Multisystem inflammatory syndrome in adults: Characteristics, treatment, and outcomes

alexandrossfakianakis shared this article with you from Inoreader Multisystem inflammatory syndrome in adults: Characteristics, treatment, and outcomes via Journal of Medical Virology ABSTRACT Following the rapidly increasing number of multisystem inflammatory syndromes in children (MIS-C), a similar clinical scenario has been observed in adult patients. Although its prevalence is low and probably related to underdiagnosis, its development can be associated with high mortality. Multisystem inflammatory syndrome in adults (MIS-A) can develop following both asymptomatic and symptomatic severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and in previously healthy people. Like MIS-C, MIS-A is a multisystem disease that can involve the cardiovascular, respiratory, gastrointestinal, dermatologic, hematologic, and neurologic systems. In addition to the clinical manifestations, the diagnosis of MIS-A requires laboratory evidence of inflammation and SARS-CoV-2 infection. The appropriate treatment for MIS-A remains unclear; anti-inflammatory agents, including intravenous immunoglobulin and corticosteroids, are commonly used. However, there are still many unknow ns regarding MIS-A. Further studies are needed to determine the true prevalence, pathogenesis, and effective treatment for MIS-A.

Viruses Responsible for Acute Respiratory Infections Before (2016‐2019) and During (2021) Circulation of the SARS‐CoV‐2 virus in Pediatric Patients in a Reference Center at Barranquilla Colombia: A Pattern Analysis

alexandrossfakianakis shared this article with you from Inoreader Viruses Responsible for Acute Respiratory Infections Before (2016‐2019) and During (2021) Circulation of the SARS‐CoV‐2 virus in Pediatric Patients in a Reference Center at Barranquilla Colombia: A Pattern Analysis via Journal of Medical Virology Summary Objective To evaluate the behavior of the viruses responsible for acute respiratory infections before (2016-2019) and after (2020-2021) the start of the circulation of the SARS-CoV-2 virus in pediatric patients treated at a reference center from Barranquilla, Colombia. Materials and methods A descriptive observational study was carried out, and data were obtained by reviewing the influenza-like illness and severe acute respiratory infection database in the pediatric population of the sentinel surveillance reference center in the district of Barranquilla during the years 2016 - 2021, applying inclusion and exclusion criteria. Results During 2016-2019, the average age of individuals was 1.3 (±1.7) years, during 2021, it was 2.3 (±3.5) years. The distribution by sex was similar, predominantly male. August and February were the months with the highest record of symptoms for 2016-2019 and 2021, respectively, the most frequent being cough, fever, shortness of breath, and diarrhea. By 2021 there was a higher use of antibiotics and antivirals reported than in 2016-2019. Most patients tested negative for viral detection. When comparing the percentage of viruses detected by age group and years of detection, positivity was lower in 2021 by every age group, and respiratory Syncytial Virus (RSV) was the most frequently detected. Conclusions There was less virus positivity in viral detection tests in the pediatric population in 2021. RSV persists as the main etiology affecting this population, especially infants. The use of antibiotic therapy in viral infections continues to be a problematic practice in their management. Sentinel surveillance can be strengthened throughout the country.

The HBV web: An insight into molecular interactomes between the Hepatitis B virus and its host en route to hepatocellular carcinoma.

alexandrossfakianakis shared this article with you from Inoreader The HBV web: An insight into molecular interactomes between the Hepatitis B virus and its host en route to hepatocellular carcinoma. via Journal of Medical Virology ABSTRACT Hepatitis B virus (HBV) is a major aetiology associated with the development and progression of hepatocellular carcinoma (HCC), the most common primary liver malignancy. Over the past few decades, direct and indirect mechanisms have been identified in the pathogenesis of HBV-associated HCC which include altered signaling pathways, genome integration, mutation-induced genomic instability, chromosomal deletions and rearrangements. Intertwining of the HBV counterparts with the host cellular factors, though well established, needs to be systemized to understand the dynamics of host-HBV crosstalk and its consequences on HCC progression. Existence of a vast array of protein-protein and protein-nucleic acid interaction databases has led to the uncoiling of the compendia of genes/gene products associated with these interactions. This review covers the existing knowledge about the HBV-host interplay and brings it down under one canopy emphasizing on the HBV-host interactomics; and thereby highlights new strategies for therapeutic advancements against HBV-induced HCC.
