    Background and Purpose of the Study: Sport-related concussions are a major public health issue, particularly so in the setting of sports. Sports dominate American culture and with millions of athletes of all ages participating in these sports these athletes predispose themselves to the risks of sport-related concussions. High-school athletes are of particular interest because of the heightened risks of long-term consequences and of particular note second impact syndrome, which is a catastrophic injury primarily reported in the adolescent aged athlete. Appropriate concussion assessment and management is necessary for reducing the possibility of these long- term effects of concussions. Properly trained and educated medical personnel such as Certified Athletic Trainers (ATC) can help reduce these risks, however, there is a lack of these qualified healthcare professionals throughout high-school sports. With this limited number of high schools employing Certified Athletic Trainers and medical professionals, coaches become the primary decision makers in their absence. Methods: This study utilized a modified mixed methods methodology with a triangulation design to measure the knowledge and attitudes of high-school coaches. A sample of 183 high school coaches participated in this study. Results: High-school coaches had adequate knowledge of sport-related concussions (Mean: 18.96) and good attitudes (Mean: 66.67) as measured by the RoCKAS-HSCH instrument. Statistically significant differences were found between high-school coaches’ knowledge and coaching experience (p=.008) and gender coached (p=.017). This indicated that those coaches who had higher levels of coaching experience and coached both male and female athlete’s had significantly higher mean knowledge scores. Significant differences also existed between high school coaches’ attitudes and experience (p=.010) as well as level of sport coached (.001) indicating those coaches with higher levels of coaching experience who coached a combination of freshman, junior varsity and varsity level sports had significantly higher mean attitude scores. Conclusion: It is vital to understand the knowledge and attitudes that coaches have about concussion and to persist with educational efforts and the assessment of their efficacy in a systemic and organized manner. Through ensuring that coaches are educated about sport-related concussion, athletic trainers and coaches can work together to make sure that the best care is being provided to athletes and develop Initiatives to assist the coaches in helping them establish team cultures that are supportive of concussion safety. Together, coaches and athletic trainers can ensure that athletes and parents are educated about concussion recognition and can work collaboratively to develop and implement concussion safety policies at their schools

    Use of adipose derived stem cells in Treacher Collins syndrome

    Objective: Treacher Collins syndrome (TCS) is a rare congenital disorder of craniofacial development. TCS occurs with an incidence of 1:50,000, and more than 60% of TCS cases have no previous family history and arise as the result of de novo mutations. The high rate of de novo mutations, together with the extreme variability in the degree to which individuals can be affected, makes the provision of genetic counseling extremely complicated. Consequently, every case of TCS is unique and needs to be assessed individually. Patients with TCS frequently undergo multiple reconstructive surgeries from birth through adulthood, which rarely are fully corrective in the long-term. The nascent field of regenerative medicine offers the promise to improve some of these treatments. In particular, structural fat grafting (SFG) seems to be a good strategy not only to restore the normal volume and contour of the face, but also to provide a source of adipose-derived stem cells (ADSCs) with a multilineage differentiation potential. In this work, we present genetical analyses of ADSC affected by TCS. Materials and methods: ADSCs from were analyzed for their stemness properties and shared many characteristics with those of a healthy subject. Screening of the genome of the TCS patient using array-Comparative Genomic Hybridization allowed us to identify some chromosomal imbalances that are probably associated with TCS. Results: We found that some alterations, involving the TIMELESS gene, were usually associated with embryonic stem cells. Conclusions: With the aim to improve the final results, we need to consider combining knowledge of genetic alterations and expression profiles as a fundamental step before starting with surgical procedures

    In vitro comparative study on the mechanical behavior of Zirconia and Polyetheretherketone in applied dental sciences

    Get PDF
    OBJECTIVE: Recently, Zirconia and polyaryletherketone (PEEK) have attracted increasing interest as reliable and safe materials in dental applications, mainly because of their good biomechanical characteristics. The aim of this study was to investigate the response to different loads by prosthetic frameworks for supported fixed partial dentures (FPDs), thus simulating osseointegrated implants. MATERIALS AND METHODS: The specimens were divided into two groups (n= 5 each). Group A: FDPs in zirconia-ceramic; Group B: FDPs in PEEK-composite. These 2 groups were subjected to vertical loads so to evaluate structural deformation; then, they have been analyzed by scanning electron microscopy (SEM) at different magnifications. RESULTS: In tested samples, different types of mechanical failures have been observed. In Zirconia-specimens, chipping is the main failure noticed in this study, mostly in distal margins of the structure. Also, peek-specimens show failure and fracture. CONCLUSIONS: Zirconia and PEEK could be considered both good materials, but several investigations are needed to use these materials as an alternative to metals for fixed partial dentures

    Mesh-tissue integration of synthetic and biologic meshes in wall surgery: brief state of art

    Get PDF
    Many studies show that surgical hernia repair with the use of prosthetic meshes can result in pain, hernia recurrence, contraction and mesh rupture. Numerous experimental studies have been conducted to understand the effect of mesh stiffness, pore size and mesh patterns on mesh biocompatibility. The purpose of this mini review is to present an overview of the contracture, adhesion, tissue regrowth and histological response characteristics of permanent and absorbable mesh. Indeed, the mechanics of mesh-human tissue interaction is poorly understood in the literature. It has been shown that early integration of biological meshes is critical for sustained hernia repair. One of the emerging experimental approaches is to combine cell-based regenerative medicine with mesh materials. Studies in preclinical models show that the use of synthetic and biological meshes with autologous cell implantation improves the biocompatibility of biomaterials, promoting key tissue regeneration processes such as adhesion and vascularisation

    The aim of the study was to evaluate the tooth extracted use as autologous tooth graft after endodontic root canal therapies used for socket preservation. To this purpose, the Tooth Transformer shredding and decontamination machine has been used. The graft obtained in this way, was inserted at the time of the extraction or at a second surgery altogether with the chosen regenerative therapy. This clinical trial enrolled patients with post-estractive defects requiring the restoration bone dimension and shape in the maxillary and mandibular zone. In addition, 98 patients with 119 extraction sockets were enrolled across 10 standardized centers. An innovative preparation method, using the dedicated automated device Tooth Transformer, able to transform autologous teeth in suitable grafting material, has been used. The extracted tooth was cleaned and treated using a Tooth Transformer and made a socket preservation. Thirteen Biopsies were realized to analyze the histologic outcomes at the average time of four months to demonstrate that the autologous tooth graft made from root after endodontic therapy should be used in human bone regeneration as graft for dental implant placement

    OBJECTIVE: Temporomandibular joint reconstructive surgery in a growing patient represents a challenging situation. Autogenous and alloplastic reconstructive options are being studied in literature; however, there are still some limitations. The objective of this case report is to evaluate a novel custom-made prosthetic system in a 12-year-old TMJ ankylosis patient. CASE PRESENTATION: The patient had complaints of temporomandibular joint ankylosis and hypoplasia. The patient had already been operated two times with autogenous grafts. Swelling and tumefaction were apparent on the right side of the face. Mouth opening was 1.5 centimeters, with limitations in lateral and protrusive movements of the jaws. Hypertonic muscles and pain upon palpation were registered. There were no signs of luxation, fracture, or traumatic avulsion. After examination, unilateral TMJ ankylosis was apparent on TC scans. Revision surgery was planned with the use of true plastic temporomandibular joint customized prosthesis. The patient underwent a TMJ reconstruction surgery using CADCAM custom-made patient specific prosthesis. The follow up period of this patient was 46 months and showed successful healing with no complications. CONCLUSIONS: Replacement of TMJ with custom made alloplastic material that is reported can be considered as a safe and useful option for growing young individuals in selected cases

    OBJECTIVE: The aim of this retrospective case series report was to evaluate the results of oral rehabilitation with extra-sinus zygomatic implant surgery with a minimum follow-up of 7.5 years. PATIENTS AND METHODS: A total of 35 patients with 87 zygomatic implants were included. The mean follow-up period of the patients was 93 months. The zygomatic implant survival and complications were evaluated as criteria for success. RESULTS: There were no implant failures. Overall success rate without complications for zygomatic implant was 88.5%. Complications developed in 4 patients (1 cutaneous fistula and 3 mucositis). According to the results on an implant basis, patients with previously failed conventional implants had greater probability of complications. Patients with quad zygomatic implants had higher incidence of complications than those with two zygomatic implants. Fully threaded implant design was associated with higher incidence of mucositis than partially threaded design. No relation was found between implant success and smoking, prosthesis type, and antagonist dentition. When conducting the analysis using the patient as unit, only the antagonist dentition showed significant difference, the worst outcome being associated with the Toronto resin prosthesis. CONCLUSIONS: Zygomatic implants can be considered as a safe alternative to conventional implant insertions and bone grafting procedures in oral rehabilitation of patients with severely atrophic maxillary bone

    Solitary fibrous tumor of parotid gland: a case report and short review of literature

    OBJECTIVE: This case report represents a solitary fibrous tumor, which is a very rare neoplasm in the parotid gland. CASE PRESENTATION: 80-year-old Caucasian female patient with palpable, immobile, painless, slow growing, semi-rigid-elastic neoplasm in the left parotid gland, that was existing for four months. There were no signs of inflammation and facial paralysis. The tumor was initially interpreted as a salivary gland neoplasm of uncertain origin. Fine needle aspiration was performed 2 times; however, the precise diagnosis was challenging. The tumor was excised, regional lymphadenectomy was performed. Morphological and immunophenotypical findings were consistent with solitary fibrous tumor of parotid gland. Currently, the patient is under regular follow-up period at 9 months with no evidence of metastasis or recurrence. CONCLUSIONS: Although very rare, solitary fibrous tumor (SFT) should be suspected in cases of slow growing, solid, well-defined nodules of the parotid gland. The SFT of the parotid gland are usually benign tumors, however there is a low risk of recurrency and malignant behavior with metastatic potential. Complete resection of the tumor should be performed since it is crucial for management without any recurrence
