Soluble epoxide hydrolase inhibitor blockage microglial cell activation in subnucleus caudalis in a persistent model of arthritis. Int Immunopharmacol 2023; 120:110320.

Abstract
Rheumatoid arthritis (RA) is a chronic condition characterized by pain and infiltration of immune cells into the joint. Immune cells can be activated, producing inflammatory cytokines, leading to continuously degenerative and inflammatory reactions and the temporomandibular joint (TMJ) can be affected by RA. In this scenario, novel targets are needed to increase treatment efficacy with minimized side effects. The epoxy-eicosatrienoic acids (EETs), are endogenous signaling molecules, playing important roles in diminishing inflammation and pain but are promptly metabolized by soluble epoxide hydrolase (sEH), generating less-bioactive acids.Therefore, sEH inhibitors is an interest therapeutic target to enhance the beneficial effect of natural EETs. TPPU is a potent sEH inhibitor that is capable of dampening EETs hydrolysis. Thus, we aimed to assess the impact of pharmacological sEH inhibition on a persistent model of albumin-induced arthritis in the TMJ, in two scenarios: first, as post-treatment, in an installed arthritic condition, and second, the protective role, in preventing the development of an arthritic condition. In addition, we investigate the influence of sEH inhibition on microglia cell activation in the trigeminal subnucleus caudalis (TSC) and in vitro experiments. Finally, we examined the astrocyte phenotype. Oral administration of TPPU, acts in multiple pathways, in a protective and reparative post-treatment, ameliorating the preservation of the TMJ morphology, reducing the hypernociception, with an immunosuppressive action reducing neutrophil and lymphocytes and pro-inflammatory cytokines in the TMJ of rats. In TSC, TPPU reduces the cytokine storm and attenuates the microglia activated P2X7/Cathepsin S/Fractalkine pathway and reduces the astrocyte activation and glutamate levels. Collectively, our findings revealed that sEH inhibition mitigates hypersensitive nociception through the regulation of microglia activation and astrocyte modulation, demonstrating the potential use of sEH inhibitors as immunoresolvents in the treatment of autoimmune disorders.

Abstract
OBJECTIVE The objective of this study was to examine whether bone mineral density (BMD) distribution in the mandibular condyle and facial morphology are associated with temporomandibular joint osteoarthritis (TMJ OA) using clinical cone beam computed tomography (CBCT) images. METHODS CBCT images of 35 adults (16 male and 19 female) were examined to obtain TMJ OA counts, cephalometric analyses, and histograms of gray values that are proportional to BMD. Mean, standard deviation (SD), and low and high gray values at the 5th and 95th percentiles (Low5 and High5) of the histograms were measured. RESULTS The female group had significantly higher values of TMJ OA counts, mean, and SD on the right mandibular condyle, High5 on both sides, and all gray value parameters for total (right + left) than the male group. CONCLUSION Comprehensive analysis of BMD distribution in the mandibular condyle can provide useful information for prognosis of TMJ OA.

Abstract
Background Artificial intelligence (AI) algorithms have been applied to diagnose temporomandibular disorders (TMDs). However, studies have used different patient selection criteria, disease subtypes, input data, and outcome measures. Resultantly, the performance of the AI models varies. Objective This study aimed to systematically summarize the current literature on the application of AI technologies for diagnosis of different TMD subtypes, evaluate the quality of these studies, and assess the diagnostic accuracy of existing AI models. Materials and methods The study protocol was carried out based on the preferred reporting items for systematic review and meta-analysis protocols (PRISMA). The PubMed, Embase, and Web of Science databases were searched to find relevant articles from database inception to June 2022. Studies that used AI algorithms to diagnose at least one subtype of TMD and those that assessed the performance of AI algorithms were included. We excluded studies on orofacial pain that were not directly related to the TMD, such as studies on atypical facial pain and neuropathic pain, editorials, book chapters, and excerpts without detailed empirical data. The risk of bias was assessed using the QUADAS-2 tool. We used Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) to provide certainty of evidence. Results A total of 17 articles for automated diagnosis of masticatory muscle disorders, TMJ osteoarthrosis, internal derangement, and disc perforation were included; they were retrospective studies, case-control studies, cohort studies, and a pilot study. Seven studies were subjected to a meta-analysis for diagnostic accuracy. According to the GRADE, the certainty of evidence was very low. The performance of the AI models had accuracy and specificity ranging from 84% to 99.9% and 73% to 100%, respectively. The pooled accuracy was 0.91 (95% CI 0.76–0.99), I2 = 97% (95% CI 0.96–0.98), p < 0.001. Conclusions Various AI algorithms developed for diagnosing TMDs may provide additional clinical expertise to increase diagnostic accuracy. However, it should be noted that a high risk of bias was present in the included studies. Also, certainty of evidence was very low. Future research of higher quality is strongly recommended.

Abstract
Temporomandibular joint disorders (TMDs) encompass a wide array of ailments affecting the temporomandibular joint (TMJ), muscles of mastication, and the allied structural framework. Myofascial pain, internal derangement of the joint, and degenerative joint diseases constitute the majority of TMDs. TMDs usually have a multifactorial etiology, and treatment modalities range from conservative therapies to surgical interventions. Low-level laser therapy (LLLT) has evolved as an efficient non-invasive therapeutic modality in TMDs. Previously conducted systematic reviews and meta-analyses have shown variable results regarding the efficiency of LLLT in TMJ disorder patients. Hence, this systematic review was carried out as an attempt to evaluate the efficacy of LLLT in the treatment of temporomandibular joint disorder patients.

Abstract
BACKGROUND The Fonseca Anamnestic Index is a questionnaire used to classify individuals with temporomandibular disorders. Previous studies have shown that the Fonseca Anamnestic Index provides a multidimensional measurement of the temporomandibular disorders construct and that the main dimension presents a good fit to the model according to the item response theory. OBJECTIVE To evaluate the between-day reliability, accuracy, and best cut-off score of the Short-Form Fonseca Anamnestic Index for the diagnosis of myogenous temporomandibular disorders. METHODS The sample consisted of 123 women (57 with myogenous temporomandibular disorders and 66 asymptomatic), evaluated by the Research Diagnostic Criteria for Temporomandibular Disorders. The participants answered the Short-Form Fonseca Anamnestic Index on two occasions with a seven-day interval between tests. For the analysis of between-day reliability, the intraclass correlation coefficient, the standard error of measurement and the minimum detectable change were used. The Receiver Operating Characteristic curve was used to determine the diagnostic accuracy and the best cut-off point. RESULTS The Short-Form Fonseca Anamnestic Index demonstrated excellent reliability (intraclass correlation coefficient≥0.95) for all items and for the total Short-Form Fonseca Anamnestic Index score (intraclass correlation coefficient=0.98; standard error of measurement=3.28; minimum detectable change=9.09). The level of accuracy of the Short-Form Fonseca Anamnestic Index for the diagnosis of myogenous temporomandibular disorders was high (area under the curve of 0.97), with a better cut-off score of 17.5 points. CONCLUSION The Fonseca Anamnestic Index should be used in its short form to classify the absence of myogenous temporomandibular disorders (scores between 0 and 15 points) or presence of myogenous temporomandibular disorders (scores between 20 and 50 points) in women.

Abstract
BACKGROUND The utility of a dedicated clinical test is dependent on the diagnostic accuracy values and the quality of the study in which the test was examined. Scales allow a summative scoring of bias within a study. At present, there are no scales advocated to measure the bias of diagnostic accuracy studies. OBJECTIVE The objective of this study was to create a new diagnostic accuracy quality scale (DAQS) that provides a quantitative summary of the methodological quality of studies evaluating clinical tests and measures. DESIGN The study used a four-round Delphi survey designed to create, revise, and develop consensus for a quality scale. METHODS The four-round Delphi involved a work team and a respondent group of experts. An initial round among the work team created a working document, which was then modified and revised, with opportunities to create new items threaded in the second round. Rounds III and IV involved voting on the importance of each of the proposed items and consensus development from the respondent group. Consensus for the selection of an item required a 75% approval for the importance of that item. RESULTS Sixteen individuals with a variety of research/professional backgrounds made up the respondent group. Modification and revision of the initial work team instrument created a scale with 21 items that reflected potential areas of methodological bias. LIMITATIONS The new scale needs validation through weighted assessment. In addition, there was a large proportion of physical therapist/researchers on the work team and the respondent group. CONCLUSIONS Systematic reviews allow summation of evidence for clinical tests and scales are essential to critique the quality of the articles included in the review. The DAQS may serve this role for diagnostic accuracy studies.

Abstract
Patients with psychiatric problems show a tendency to develop temporomandibular disorders (TMD). Particularly, patients with schizophrenia are quite likely to have signs and symptoms of TMD due to the impairment of their oral health, the use of antipsychotic drugs, and other general health problems. In nonschizophrenic populations, TMD have been considered as the main cause of nondental pain in the orofacial region, involving mechanisms associated with changes in masticatory activity at the cortical and neuromuscular levels. Individuals with schizophrenia do not usually complain of pain, and TMD is misdiagnosed in this population. In this paper, we aimed to review the clinical aspects of TMD in people with schizophrenia on antipsychotic drug therapy.

Abstract
SYNOPSIS Physical therapists have an important role on the interprofessional team to provide care for people with temporomandibular disorders (TMDs). Diagnostic classification is a challenge in this population, given the complexities inherent in presentations of headache and orofacial pain, and is critical to selecting the appropriate intervention. The objectives of this paper were (1) to characterize the epidemiology and pathophysiology of the TMDs most commonly seen in the outpatient clinic, (2) to describe a systems screen to be used in the physical therapy examination to determine the need for interprofessional referral, and (3) to propose an approach for physical therapists to examine, evaluate, and classify patients with TMDs, based on previously validated methodologies. A modification of the diagnostic framework of the International Headache Society has provided the basis for the systems screen of people presenting with orofacial pain. The physical therapy examination and evaluation is based on the Diagnostic Criteria for TMD, developed and validated by a consortium of specialists from the American Academy of Orofacial Pain. LEVEL OF EVIDENCE Diagnosis, level 5.

Abstract
Temporomandibular joint disorders (TMDs) are common and may cause temporomandibular joint (TMJ) locking, pain, and disability. Evidence supports use of manual therapy and exercise for treatment of TMDs including disk displacement limiting full mouth opening, TMJ 'closed lock'. Only limited case studies describe management of TMJ 'open lock', a condition due to posterior disk displacement (PDD) or TMJ anterior dislocation (TMJ-AD). Reported treatment for open lock includes splinting and intraoral joint manipulation. This case report describes a novel extraoral automobilization using the mandibular elevator muscles to treat TMJ open lock in a 22-year-old male after intraoral joint mobilization failed. The exercise program used to restore neuromuscular control for post-reduction management is described. Short term results of automobilization were excellent with restored ability to swallow, speak normally, and achieve occlusion. Long term results at 14 months were good: the patient was pain-free, could swallow and speak normally, had no recurrence of TMJ locking, and minimal disability. Limited right lateral excursion range and left mandibular deviation during mouth opening indicated possible persistence of PDD. This case suggests that mandibular elevator automobilization and masticatory muscle exercise may be useful to treat TMJ open lock and should be considered to treat PDD and TMJ-AD.

Abstract
The aim of the present study was to determine the association between the severity of temporomandibular disorder (TMD) and mandibular range of motion (ROM). For such, a cross-sectional study was carried out with a sample of 92 women from the university community. The Fonseca's anamnestic index (FAI) was used to determine the severity of TMD, as follows: without TMD (n = 23), mild TMD (n = 23), moderate TMD (n = 23), and severe TMD (n = 23). Mouth opening, lateral excursion and protrusion of the mandible were measured. Spearman's correlation coefficients were calculated to determine the association between the FAI and mandibular ROM. Comparisons among groups were performed using the Kruskal-Wallis test with Dunn's post hoc test. No significant associations were found between TMD severity based on the classification of the FAI and ROM of functional mouth opening (rs = -0.001, p = 0.987), maximum active mouth opening (rs = -0.023, p = 0.822), passive mouth opening (rs = -0.026, p = 0.803), left lateral excursion (rs = 0.125, p = 0.231), right lateral excursion (rs = 0.087, p = 0.406) or protrusion (rs = -0.148, p = 0.157). Moreover, no statistically significant differences among severity groups were found (p > 0.05). Based on the findings of the present study, the severity of signs and symptoms of TMD was not associated with mandibular range of motion.

Abstract
OBJECTIVE The purpose of this study was to evaluate the accuracy of infrared thermography of the central point of the masseter and anterior temporalis muscles for the diagnosis of myogenous temporomandibular disorder (TMD). METHODS This is an observational study of university women with and without TMD. Through the use of the Research Diagnostic Criteria for Temporomandibular Disorders, 104 women were divided into a TMD group (n = 52) and control group (n = 52). All volunteers had their masseter and anterior temporalis muscles evaluated by infrared thermography. The receiver operating characteristic (ROC) curve was used to determine the accuracy of diagnosis (area under the ROC curve), the best cut-off point, sensitivity, and specificity. RESULTS No significant differences were observed (P > .05) in the skin surface temperature of the masticatory muscles, when the groups were compared. With regard to the ROC curve, the area under the curve was lower than the recommended for all the muscles tested, ranging from 0.433 to 0.502. CONCLUSION The findings of this study suggest that infrared thermography of the masticatory muscles is not an accurate instrument for the myogenous TMD diagnosis.

Abstract
The high incidence and diversity of factors attributed to the etiology of patellofemoral pain syndrome (PFPS) makes the diagnosis of this problem somewhat complex and susceptible to misinterpretation. Currently, there is not a defined set of procedures considered as ideal to diagnose PFPS. To investigate the diagnostic accuracy of clinical and functional tests used to diagnose PFPS through a systematic review. We searched relevant studies in the databases Medline, CINAHL, SPORTDiscus and Embase. The QUADAS score was used to assess the methodological quality of the eligible studies. We analyzed data that indicated the diagnostic properties of tests, such as sensibility, specificity, positive (LR+) and negative (LR-) likelihood ratio, and predictive values. The search identified 16,169 potential studies and five studies met the eligibility criteria. The 5 studies analyzed 25 tests intending to accurately diagnose PFPS. Two tests were analyzed in two studies and were possible to perform a meta-analysis. Within the five studies included, one study had high methodological quality, two studies had good methodological quality and two studies had low methodological quality. Two tests, the patellar tilt (LR+ = 5.4 and LR- = 0.6) and squatting (LR+ = 1.8 and LR- = 0.2), had values that show a trend for the diagnosis of PFPS (LR+ >5.0 and LR- <0.2), however their values do not represent clear evidence regarding diagnostic properties as suggested in the literature (LR+ >10 and LR- <0.1). Future diagnostic studies should focus on the sample homogeneity and standardization of tests analyzed so future systematic reviews can determine with more certainty the accuracy of the tests for diagnosis of PFPS.

Kiga N. Histochemistry for studying structure and function of the articular disc of the human temporomandibular joint. Eur J Histochem 2012; 56:e11. [PMID: 22472889 PMCID: PMC3352130 DOI: 10.4081/ejh.2012.e11] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/20/2011] [Accepted: 12/21/2011] [Indexed: 11/23/2022] Open
Abstract
The articular disc of the temporomandibular joint (TMJ) is composed of fibrocartilage, and the extracellular matrix of this disc is composed mainly of collagen, glycosaminoglycan and proteoglycans. Research on the changes that occur in the composition of the articular disc of the TMJ is necessary for understanding the basis of the pathological process of internal derangement (ID), and a number of reports have been published in recent years on the application of refined histochemical techniques to investigate the structure and function of the TMJ. The direction of future TMJ disc studies should be towards obtaining more evidence to support previous results, and should hopefully be of practical use in terms of prevention and cure of ID.
