The methodological quality of systematic reviews comparing temporomandibular joint disorder surgical and non-surgical treatment
<p>Abstract</p> <p>Background</p> <p>Temporomandibular joint disorders (TMJD) are multifactor, complex clinical problems affecting approximately 60–70% of the general population, with considerable controversy about the most effective treatment. For example, reports claim success rates of 70% and 83% for non-surgical and surgical treatment, whereas other reports claim success rates of 40% to 70% for self-improvement without treatment. Therefore, the purpose of this study was to (1) identify systematic reviews comparing temporomandibular joint disorder surgical and non-surgical treatment, (2) evaluate their methodological quality, and (3) evaluate the evidence grade within the systematic reviews.</p> <p>Methods</p> <p>A search strategy was developed and implemented for MEDLINE, Cochrane Library, LILACS, and Brazilian Dentistry Bibliography databases. Inclusion criteria were: systematic reviews (± meta-analysis) comparing surgical and non-surgical TMJD treatment, published in English, Spanish, Portuguese, Italian, or German between the years 1966 and 2007(up to July). Exclusion criteria were: <it>in vitro </it>or animal studies; narrative reviews or editorials or editorial letters; and articles published in other languages. Two investigators independently selected and evaluated systematic reviews. Three different instruments (AMSTAR, OQAQ and CASP) were used to evaluate methodological quality, and the results averaged. The GRADE instrument was used to evaluate the evidence grade within the reviews.</p> <p>Results</p> <p>The search strategy identified 211 reports; of which 2 were systematic reviews meeting inclusion criteria. The first review met 23.5 ± 6.0% and the second met 77.5 ± 12.8% of the methodological quality criteria (mean ± sd). In these systematic reviews between 9 and 15% of the trials were graded as high quality, and 2 and 8% of the total number of patients were involved in these studies.</p> <p>Conclusion</p> <p>The results indicate that in spite of the widespread impact of TMJD, and the multitude of potential interventions, clinicians have expended sparse attention to systematically implementing clinical trial methodology that would improve validity and reliability of outcome measures. With some 20 years of knowledge of evidence-based healthcare, the meager attention to these issues begins to raise ethical issues about TMJD trial conduct and clinical care.</p
Principles of cartilage tissue engineering in TMJ reconstruction
Diseases and defects of the temporomandibular joint (TMJ), compromising the cartilaginous layer of the condyle, impose a significant treatment challenge. Different regeneration approaches, especially surgical interventions at the TMJ's cartilage surface, are established treatment methods in maxillofacial surgery but fail to induce a regeneration ad integrum. Cartilage tissue engineering, in contrast, is a newly introduced treatment option in cartilage reconstruction strategies aimed to heal cartilaginous defects. Because cartilage has a limited capacity for intrinsic repair, and even minor lesions or injuries may lead to progressive damage, biological oriented approaches have gained special interest in cartilage therapy. Cell based cartilage regeneration is suggested to improve cartilage repair or reconstruction therapies. Autologous cell implantation, for example, is the first step as a clinically used cell based regeneration option. More advanced or complex therapeutical options (extracorporeal cartilage engineering, genetic engineering, both under evaluation in pre-clinical investigations) have not reached the level of clinical trials but may be approached in the near future. In order to understand cartilage tissue engineering as a new treatment option, an overview of the biological, engineering, and clinical challenges as well as the inherent constraints of the different treatment modalities are given in this paper
Obstructive sleep apnoea: A review of the orofacial implications
The document attached has been archived with permission from the Australian Dental Association (8th Jan 2008). An external link to the publisher’s copy is included.Obstructive sleep apnoea is a complex multifactorial condition produced by a combination of anatomical and physiological factors. There is a significant associated mortality and morbidity to obstructive sleep apnoea. There is an at least 25 per cent increased mortality from cardiovascular disease when obstructive sleep apnoea patients are compared to age and gender matched healthy people. Obstructive sleep apnoea sufferers also have a much higher industrial and motor vehicle accident rate. Management of the condition should be undertaken by a multidisciplinary team including respiratory physicians, sleep laboratory technicians, otorhinolaryngologists, oral and maxillofacial surgeons and dental specialists. The diagnostic and therapeutic interactions of team members are the key to successful treatment. The treatment regime utilises nasal continuous positive airway pressure devices, mandibular advancement splints and soft and hard tissue surgery. This review provides the dental practitioner with an introduction to obstructive sleep apnoea with particular emphasis on the orofacial aspects.David Sherring, Norman Vowles, Ral Antic, Suren Krishnan and Alastair N Gos

The impact of currently licensed therapies on viral and immune responses in Chronic Hepatitis B: considerations for future novel therapeutics.
Despite the availability of a preventative vaccine, chronic hepatitis B (CHB) remains a global healthcare challenge with the risk of disease progression due to cirrhosis and hepatocellular carcinoma. Although current treatment strategies, interferon and nucleos(t)ide analogues have contributed to reducing morbidity and mortality related to CHB, these therapies are limited in providing functional cure. The treatment paradigm in CHB is rapidly evolving with a number of new agents in the developmental pipeline. However, until novel agents with functional cure capability are available in the clinical setting, there is a pressing need to optimize currently licensed therapies. Here, we discuss current agents used alone and/or in combination strategies along with the impact of these therapies on viral and immune responses. Novel treatment strategies are outlined, and the potential role of current therapies in the employment of pipeline agents is discussedWellcome Trust Clinical Research Training Fellowship (107389/Z/15/Z)NIHR Academic Clinical LectureshipBarts Charity Project Grants (723/1795 and MGU/0406NIHR Research for patient benefit award (PB‐PG‐0614‐34087) to PTF
Just type polyana and press Enter: a post-processing application designed with simplicity of use in mind
We present a new version of POLYANA, an application that computes radial distribution functions for centres of mass of whole molecules or subunits thereof, based on DL_POLY trajectories. User friendliness and ease of future extensions were fundamental design principles of POLYANA development. Thus, the new version adds, among others, a flexible syntax to define groups of atoms; calculation of radial distribution functions beyond half the simulation cell size; OpenMP parallelism and other features on top of existing functionality. The impatient user can compile and execute it immediately to obtain molecular radial distribution functions; on the other hand, easy to learn directives offer more advanced capabilities. POLYANA is a self-contained Fortran code, built in a modular fashion that makes it easy to add new functions. It is free and open-source and it is distributed under the MIT license. © 2019 Informa UK Limited, trading as Taylor & Francis Group
