Comparison of stress distribution between zirconia/alloy endocrown and CAD/CAM multi-piece zirconia post-crown: three-dimensional finite element analysis

paythelady.61 shared this article with you from Inoreader Comparison of stress distribution between zirconia/alloy endocrown and CAD/CAM multi-piece zirconia post-crown: three-dimensional finite element analysis Via Latest Results for Clinical Oral Investigations Abstract Objectives This study aimed to evaluate a digital multi-piece zirconia post-crown to restore a mandibular second molar with extensive coronal loss and limited restoration space, and to compare the stress distribution between endocrowns made of zirconia or alloy and CAD/CAM multi-piece zirconia post-crowns. Material and methods Four three-dimensional finite element analysis models of a mandibular second molar with extensive coronal loss and limited restoration space were created as follows: (A) intact molar; (B) zirconia endocrown restored molar; (C) multi-piece post-crown restored-molar with tapered nail; (D) multi-piece post-crown restored molar with T-shaped nail. Models C and D were divided into two subgroups according to the material type: C1/D1, zirconia; C2/D2, NiCr alloy. The maximum modified von Mises failure criterion (mvM) stresses were calculated, and the stress distribution was recorded to analyze the effects of the restoration and material types on the biomechanical properties of dentin and prosthesis. Results The maximum mvM stress of dentin in model B (33.80 MPa) was lower compared with models C (C1, 37.81 MPa; C2, 36.36 MPa) and D (D1, 36.34 MPa; D2, 34.97 MPa) under vertical load, but the opposite was observed under oblique load. The highest mvM stress was concentrated in the nail region located in the root canal, and the T-shaped nail values were greater than the tapered nail, whereas model D with T-shaped nail showed a lower mvM stress level in dentin compared with Model C with tapered nail. Conclusions The digital multi-piece zirconia post-crown is a potential approach to restore mandibular second molars with extensive coronal loss and limited restoration space. Clinical relevance The digital multi-piece zirconia post-crown has potential to restore mandibular second molars with extensive coronal loss and limited restoration space using an innovative approach.

The implicated clinical factors for outcomes in 304 patients with salivary duct carcinoma: Multi‐institutional retrospective analysis in Japan

paythelady.61 shared this article with you from Inoreader The implicated clinical factors for outcomes in 304 patients with salivary duct carcinoma: Multi‐institutional retrospective analysis in Japan Via Head & Neck Abstract Background Salivary duct carcinoma (SDC) is a high-grade salivary malignancy that frequently occurs as the carcinomatous component of carcinoma ex pleomorphic adenoma. We herein examined the clinical factors affecting outcomes in a large cohort of SDC. Methods We selected 304 SDC cases and investigated clinical characteristics and the factors affecting outcomes. Results The median age of the cases examined was 68 years, the most common primary site was the parotid gland (238 cases), and there was a male predominance (M/F = 5:1). Outcomes were significantly worse when the primary tumor site was the minor salivary glands (SG) than when it was the major SG. Outcomes were also significantly worse in pN(+) cases (161 cases) than in pN0 cases, particularly those with a metastatic lymph node number ≥11. The cumulative incidence of relapse and distant metastases was significantly higher in stage IV cases than in stage 0–III cases. Conclusions The absolute number of lymph node metastases, higher stages, and the minor SG as the primary tumor site were identified as factors affecting the outcome of SDC. View on the web Inoreader.

Systemic Steroids for Otolaryngology–Head and Neck Surgery Disorders: An Evidence-Based Primer for Clinicians

paythelady.61 shared this article with you from Inoreader Systemic Steroids for Otolaryngology–Head and Neck Surgery Disorders: An Evidence-Based Primer for Clinicians Via SAGE-Journals: Otolaryngology-Head and Neck Surgery: Table of Contents Otolaryngology–Head and Neck Surgery, Ahead of Print. ObjectiveTo offer pragmatic, evidence-informed guidance on the use of systemic corticosteroids (SCS) for common otolaryngologic disorders.Data SourcesPubMed, Cochrane Library, and American Academy of Otolaryngology–Head and Neck Surgery Foundation clinical practice guidelines.Review MethodsA comprehensive search of published literature through November 2021 was conducted on the efficacy of SCS, alone or in combination with other treatments, for managing disorders in otolaryngology and the subdisciplines. Clinical practice guidelines, systematic reviews, and randomized controlled trials, when available, were preferentially retrieved. Interventions and outcomes of SCS use were compiled to generate summary tables and narrative synthesis of findings.ConclusionsEvidence on the effectiveness of SCS varies widely across otolaryngology disorders. High-level evidence supports SCS use for Bell's palsy, sinonasal polyposis, a nd lower airway disease. Conversely, evidence is weak or absent for upper respiratory tract infection, eustachian tube dysfunction, benign paroxysmal positional vertigo, adenotonsillar hypertrophy, or nonallergic rhinitis. Evidence is indeterminate for acute laryngitis, acute pharyngitis, acute sinusitis, angioedema, chronic rhinosinusitis without polyps, Ménière's disease, postviral olfactory loss, postoperative nerve paresis/paralysis, facial pain, and sudden sensorineural hearing loss.Implications for PracticeClinicians should bring an evidence-informed lens to SCS prescribing to best counsel patients regarding the risks, anticipated benefits, and limited data on long-term effects. Alternate routes of corticosteroid administration—such as sprays, drops, inhalers, and intralesional injections—may be preferable for many disorders, particularly those that are self-limited or require a prolonged duration of therapy. Prudent use of SCS reduces the risk of medication-related ad verse effects. Clinicians who are conversant with high-level evidence can achieve optimal outcomes and stewardship when prescribing SCS.

Cancer Risk Associated with Continuous Positive Airway Pressure: A National Study

paythelady.61 shared this article with you from Inoreader Cancer Risk Associated with Continuous Positive Airway Pressure: A National Study Via The Laryngoscope Objective In 2021 the U.S. FDA issued a Class 1 safety recall notice for specific devices due to a risk of carcinogen exposure. The objective of this study was to evaluate reports of cancer linked to CPAP devices to understand implications for the field of sleep medicine. Methods Cases of cancer involving CPAP devices were retrieved from the MAUDE database from 2014 to 2021 and analyzed with descriptive statistics. Results A total of 2571 patient injuries were associated with CPAP. Reports of cancer (n = 209; 4.62%) were the second most commonly documented patient problem associated with CPAP, although 1950 (43.13%) patients had a device problem without an associated injury. Of the 209 cancer cases associated with CPAP, 200 (95.7%) of the adverse event reports were received by the FDA in 2021. There were 174 (9.15%) descriptions of the CPAP polyurethane sound abatement foam degrading in association with a cancer diagnosis, but degradation was more commonly not associated with malignancy (n = 1728; 90.85%). Other frequently documented CPAP device problems included broken devices (n = 279; 6.92%), fire (n = 182; 4.51%), and patient–device incompatibility (n = 144; 3.57%). Conclusion Malignancy associated with CPAP devices has been reported; however, future studies are required to establish causation. Given 95.7% of those documented cases were reported in 2021, otolaryngologists should be prepared to discuss the risks of carcinogenesis associated with CPAP. The otolaryngology community should also be aware of the potential bandwagon effect and the implications for CPAP compliance. Level of Evidence 4 Laryngoscope, 2022 View on the web Inoreader.

Key Points on Functional Rhinoplasty Patient Evaluation

paythelady.61 shared this article with you from Inoreader Key Points on Functional Rhinoplasty Patient Evaluation Via Latest Results for Current Otorhinolaryngology Reports Abstract Purpose of Review The goal of this review is to discuss the key points in the evaluation of patients for functional nasal airway surgery to help optimize outcomes. Recent Findings Development of the clinical practice guideline for rhinoplasty was a recent effort to guide perioperative care and workup of patients undergoing rhinoplasty. This guideline highlighted the importance of patient reported outcome measures (PROMs) in evaluating surgical outcomes. There has also been an increase in publications regarding intervention in the pediatric population. Finally, there has been more work into the exact mechanics of nasal airway obstruction and lateral wall insufficiency. Summary Functional rhinoplasty lacks clear objective tests to help guide surgery. PROMs are important in evaluating surgical outcomes and advances in technology such as computational fluid dynamics, and virtual surgical planning will hopefully provide insight into airflow patterns and where surgical intervention should be focused to maximize patient outcomes.
