ABSTRACT
This study aims to conduct a systematic analysis of literature published between 1 January 2018 and 1 September 2022, exploring factors influencing the progression or development of temporomandibular disorders (TMD), diagnosed using the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) or Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD). Three electronic databases were reviewed to identify papers that examined TMD factors using DC/TMD or RDC/TMD. Inclusion criteria encompassed original research published in English between 1 January 2018 and 1 October 2022, online, and complete DC/TMD or RDC/TMD studies on human participants aged 18 or older. Two authors independently assessed the risk of bias using The Joanna Briggs Institute (JBI) Analytical cross-sectional studies' Critical Appraisal Tool. Of 1478 articles, 11 were included. The studies revealed strong associations between TMD and factors such as female, poor sleep quality, depression, oral parafunction, anxiety, somatization, and anatomical features. However, variables such as education, living conditions, socioeconomic status, marital status, chronic pain, and stress did not exhibit statistically significant correlations. Based on the obtained data, it can be concluded that the causes of TMD are largely related to psychological factors, which supports the biopsychosocial theory of the disorder.
ABSTRACT
Temporomandibular joint disorders (TMDs) are ailments affecting the jaws and allied structures, resulting in many pathologies (TMJ hypermobility, internal disc derangement, bone changes, degenerative disorders, and ankylosis). Pain, clicking or crepitus, restricted range of motion, deranged jaw function, and deflected or deviated mouth opening and closing are the commonly observed manifestations in TMDs. Internal derangement refers to an aberrant relation of the articular disc to the condyle and fossa, respectively. Conventional therapies highlight the role of non-invasive conservative treatment strategies, namely joint unloading, anti-inflammatory drugs, and physiotherapy. Current literature has emphasized the use of corticosteroids and platelet-rich plasma (PRP) as treatment strategies in TMDs. This study aimed to evaluate whether intra-articular injection of PRP after normal saline lavage in TMJ minimizes the symptoms of TMDs, as compared to injection of normal saline. Thirty patients with TMD according to research diagnostic criteria (RDC) were selected. One group received arthrocentesis with normal saline, and the other group received arthrocentesis with PRP injection. The patients were assessed for pain, maximum inter-incisal mouth opening, bite force, and TMJ sounds. TMDs treated by PRP injection had slightly better results. More studies are required to substantiate the outcome. Injections of PRP were more effective in reducing the symptoms than arthrocentesis with normal saline.

Objective: This study aimed to investigate the prevalence of temporomandibular disorders (TMD) in patients with chronic hemodialysis and evaluate the risk factors of developing TMD.Methods: One hundred forty-six subjects were included in the study. The examination for TMD was based on the standardized Research Diagnostic Criteria for Temporomandibular Disorders. Axis I protocol was used to evaluate the prevalence of TMD sub-diagnoses.Results: The prevalence of TMD was 41.5% in hemodialysis patients and significantly higher than in the control group. The most common symptom was TMJ pain, and the most common TMD subtype was muscular type. Female patients had significantly higher TMD than males. C-reactive protein, hemoglobin, parathyroid hormone, and albumin were significantly associated with TMD.Conclusion: There was an elevated prevalence of TMD in hemodialysis patients.

BACKGROUND: Sporadic inclusion body myositis (s-IBM) is rare in India. AIM: The aim of this study was to diagnose s-IBM according to the European Neuromuscular Center (ENMC) IBM research diagnostic criteria 2011. MATERIALS AND METHODS: A retrospective review of patient records diagnosed as s-IBM according to the above criteria during the period from January 2010 to May 2015 was done with an emphasis on pattern of muscle weakness.Serumcreatine kinase (CK) andelectromyography (EMG) were noted. Muscle biopsy was evaluated with basic panel of histochemical stains including Congo red stain. Immunohistochemistry (IHC) with ubiquitin was done in 10 biopsies. IHC for major histocompatibility complex-1 and electron microscopy studies were not performed. RESULTS: The diagnosis of s-IBM constituted 5 clinicopathologically defined, 12 clinically defined, and 10 probable IBM in the study period. There was male predominance with median age at 51 and duration of disease varying from 1-5 years. All the patients presented with insidious onset of muscle weakness of quadriceps and/or forearm flexors. CK varied from 57-2939 IU/L. EMG was myopathic in 22, mixed in 2, and neuropathic in 3. Endomysial inflammation was seen in 23 (85.19%) and rimmed vacuoles in 24 (88.89%). Amyloid was demonstrated in only 5 (18.52%) and ubiquitin in 2 biopsies. Mitochondrial abnormalities were seen in 92.59% biopsies. CONCLUSIONS: Application of the ENMC IBM research diagnostic criteria allowed diagnosis of clinically-defined and probable IBM in the absence of all pathology criteria. Rimmed vacuoles in 88.89% of biopsies indicate presentation at a late stage. Use of ancillary techniques can improve diagnostic yield.

INTRODUCTION: Validity of the 2014 traumatic encephalopathy syndrome (TES) criteria, proposed to diagnose chronic traumatic encephalopathy (CTE) in life, has not been assessed. METHODS: A total of 336 consecutive brain donors exposed to repetitive head impacts from contact sports, military service, and/or physical violence were included. Blinded to clinical information, neuropathologists applied National Institute on Neurological Disorders and Stroke/National Institute of Biomedical Imaging and Bioengineering CTE criteria. Blinded to neuropathological information, clinicians interviewed informants and reviewed medical records. An expert panel adjudicated TES diagnoses. RESULTS: A total of 309 donors were diagnosed with TES; 244 donors had CTE pathology. TES criteria demonstrated sensitivity and specificity of 0.97 and 0.21, respectively. Cognitive (odds ratio [OR] = 3.6; 95% confidence interval [CI]: 1.2-5.1), but not mood/behavior or motor symptoms, were significantly associated with CTE pathology. Having Alzheimer's disease (AD) pathology was significantly associated with reduced TES accuracy (OR = 0.27; 95% CI: 0.12-0.59). DISCUSSION: TES criteria provided good evidence to rule out, but limited evidence to rule in, CTE pathology. Requiring cognitive symptoms in revised criteria and using AD biomarkers may improve CTE pathology prediction.

OBJECTIVE: To develop a beta version of a preliminary set of empirically derived research diagnostic criteria (RDC) for burning mouth syndrome (BMS) through expert consensus, which can then be taken into a test period before publication of a final RDC/BMS. DESIGN: A 6 round Delphi process with twelve experts in the field of BMS was used. The first round formed a focus group during which the purpose of the RDC and the definition of BMS was agreed upon, as well as the structure and contents. The remaining rounds were carried out virtually via email to achieve a consensus of the beta version of the RDC/BMS. RESULTS: The definition of BMS was agreed to be 'an intraoral burning or dysaesthetic sensation, recurring daily for more than 2 hours per day over more than 3 months, without evident causative lesions on clinical examination and investigation'. The RDC was based upon the already developed and validated RDC/TMD and formed three main parts: patient self-report; examination; and psychosocial self-report. A fourth additional part was also developed listing aspirational biomarkers which could be used as part of the BMS diagnosis where available, or to inform future research. CONCLUSION: This Delphi process has created a beta version of an RDC for use with BMS. This will allow future clinical research within BMS to be carried out to a higher standard, ensuring only patients with true BMS are included. Further validation studies will be required alongside refinement of the RDC as trialling progresses.

BACKGROUND: The terminology "temporomandibular disorders" (TMDs) encompasses a wide spectrum of conditions. Several hypothesized causes are occlusal disharmony, muscle hyperactivity, central pain mechanisms, psychological distress, and trauma. In day-to-day practice, TMDs had become more prevalent in Indian population due to changed dietary pattern and food habits, excessive stress of modern life, and other environmental causes. This study is an attempt to find the prevalence of TMDs in North Indian population. AIMS: The present study is taken into account to determine the prevalence of TMDs on the basis of signs and symptoms based on the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD). MATERIALS AND METHODS: The present cross-sectional study was conducted in the Department of Oral Medicine and Radiology. A total of 1009 patients aged between 6 and 80 years with a mean age of 42.04 ± 16.8 years seeking dental treatment from January 2016 to June 2017 were included in the study. All the patients were screened for TMD sign and symptoms. The demographic data and the signs and symptoms of TMDs were recorded in designed structured questionnaires which were based on the RDC/TMD criteria. RESULTS: The study population consisted of 1009 patients aged between 6 and 80 years. In the present study population, based on RDC/TMD criteria, the incidence of clicking sound (42.5%) was highest in TMD joint followed by deviation of mandible on mouth opening (40.8%), internal derangement (36.8%), myofacial pain dysfunction syndrome (33.7%), osteoarthritis (29.5%), crepitus (25.8%), joint tenderness (5.8%), and pain on mouth opening (4.8%). CONCLUSION: Clicking sound was the most common sign of TMD disorders in Indian population.
ABSTRACT
BACKGROUND AND PURPOSE: Temporomandibular disorders (TMD) are among the most frequent pathologies of the stomatognathic system. One problem often associated with TMD is the psychoemotional status. The aim of study was to evaluate the psychoemotional status of young adults with pain symptoms associated with TMD. MATERIAL AND METHODS: We analyzed the data of 260 volunteers. The Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) form was used to diagnose TMD. The relationships between TMD/RDC clinical diagnoses and psychoemotional status, as described by the Beck's Depression Inventory (BDI) and Perceived Stress Scale (PSS-10), were analyzed. We divide the group into four on the basis of RDC/TMD Axis I diagnosis. Group 0 included 30 students lacking TMD symptoms. Group I consisted of 30 people with myofascial pain (group IA in RDC/TMD). Group II contained 23 people with disk displacement with reduction (group IIA in RDC/TMD). Group III contained ten people (Group III diagnosis, often associated with pain). RESULTS: We did not find statistically significant differences between the study groups. In subjects with pain (Groups I and III), we found the mean value on the BDI and PSS-10 scales to be higher than among the pain-free subjects (Groups 0 and II). CONCLUSION: In young adults with TMD accompanied by pain, psychoemotional status should also be evaluated.

OBJECTIVE: Since its introduction to the psychiatric nomenclature in 2013, research on avoidant/restrictive food intake disorder (ARFID) has proliferated highlighting lack of clarity in how ARFID is defined. METHOD: In September 2018, a small multi-disciplinary pool of international experts in feeding disorder and eating disorder clinical practice and research convened as the Radcliffe ARFID workgroup to consider operationalization of DSM-5 ARFID diagnostic criteria to guide research in this disorder. RESULTS: By consensus of the Radcliffe ARFID workgroup, ARFID eating is characterized by food avoidance and/or restriction, involving limited volume and/or variety associated with one or more of the following: weight loss or faltering growth (e.g., defined as in anorexia nervosa, or by crossing weight/growth percentiles); nutritional deficiencies (defined by laboratory assay or dietary recall); dependence on tube feeding or nutritional supplements (≥50% of daily caloric intake or any tube feeding not required by a concurrent medical condition); and/or psychosocial impairment. CONCLUSIONS: This article offers definitions on how best to operationalize ARFID criteria and assessment thereof to be tested in existing clinical populations and to guide future study to advance understanding and treatment of this heterogeneous disorder.

BACKGROUND: Previous studies have demonstrated a strong association between primary headaches (HAs) and temporomandibular disorders (TMDs), specifically the myofascial pain subtype of TMD (MP TMD). The role of anxiety and depression in presentation and maintenance of MP TMD and migraine is previously demonstrated. Therefore, the objective of the current study was to evaluate the modification effect of anxiety and depression on the possible association of MP TMD and migraine. METHODS: In this retrospective case-control study, individuals between 15 and 45 years old who were diagnosed with migraine HA according to the international classification of headache disorder-II (ICHD-II) were selected as case subjects (n = 65). Non-HA control subjects were matched by sex and age (n = 63). Research diagnostic criteria (RDC/TMD) (Axis I) was used to diagnose patients with MP TMD; other subtypes of RDC/TMD Axis I were excluded from the study. Subjects' anxiety and depression were screened using Persian version of Hospital Anxiety and Depression Scale-14. Chi-square and Mantel-Haenszel tests were used to analyze the data. P < 0.05 was considered statistically significant. RESULTS: A significant association was found between migraine and MP TMD so that subjects with MP TMD had a five times chance of developing HA (P < 0.001). Further analysis using stratification method revealed that anxiety and depression have a modification effect in the association of MP TMD and HA and MP TMD patients with anxiety or depression had more chance of developing migraine HA (P = 0.003). CONCLUSION: Association between HA and TMD was observed in this study. Besides, we depicted that anxiety and depression interact in this association so that patients who did not have anxiety or depression did not demonstrate an association between TMD and HA. We suggest further studies to confirm the modifying effects of anxiety and depression.

This article analyzes whether psychiatric disorders can be considered different from non-psychiatric disorders on a nosologic or semiologic point of view. The supposed difference between psychiatric and non-psychiatric disorders relates to the fact that the individuation of psychiatric disorders seems more complex than for non-psychiatric disorders. This individuation process can be related to nosologic and semiologic considerations. The first part of the article analyzes whether the ways of constructing classifications of psychiatric disorders are different than for non-psychiatric disorders. The ways of establishing the boundaries between the normal and the pathologic, and of classifying the signs and symptoms in different categories of disorder, are analyzed. Rather than highlighting the specificity of psychiatric disorders, nosologic investigation reveals conceptual notions that apply to the entire field of medicine when we seek to establish the boundaries between the normal and the pathologic and between different disorders. Psychiatry is thus very important in medicine because it exemplifies the inherent problem of the construction of cognitive schemes imposed on clinical and scientific medical information to delineate a classification of disorders and increase its comprehensibility and utility. The second part of this article assesses whether the clinical manifestations of psychiatric disorders (semiology) are specific to the point that they are entities that are different from non-psychiatric disorders. The attribution of clinical manifestations in the different classifications (Research Diagnostic Criteria, Diagnostic Statistic Manual, Research Domain Criteria) is analyzed. Then the two principal models on signs and symptoms, i.e. the latent variable model and the causal network model, are assessed. Unlike nosologic investigation, semiologic analysis is able to reveal specific psychiatric features in a patient. The challenge, therefore, is to better define and classify signs and symptoms in psychiatry based on a dual and mutually interactive biological and psychological perspective, and to incorporate semiologic psychiatry into an integrative, multilevel and multisystem brain and cognitive approach.

In addition to palpation tests, dynamic/static tests have been proposed to complement temporomandibular disorders (TMD) patients' evaluation in the clinical setting. The aim of this study was to assess the intra- and inter-observer reliability of the palpation tests and of the dynamic/static tests, and to determine whether those tests would yield comparable outcomes in terms of pain diagnoses. Ninety-eight (N = 98) consecutive adult patients were examined during 2 clinical sessions by 2 independent examiners, based on muscle and joint palpation techniques described in the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD). They also underwent dynamic/static tests. The intra-observer reliability of palpation tests was generally poor, with fair-to-good to excellent ICC values only for the superior masseter and intra-oral sites. The inter-observer reliability of palpation was fair-to-good for muscles, but it was poor for the TMJ lateral pole. Both intra- and inter-observer reliability for the dynamic/static tests varied from fair-to-good to excellent. The intra-observer reliability for muscle pain diagnoses based on palpation tests was between poor and fair-to-good, whereas the inter-observer reliability was excellent. The intra-observer reliability for pain diagnoses based on dynamic/static tests was fair-to-good, and the inter-observer reliability varied from fair-to-good to excellent. CONCLUSIONS: Some features of the dynamic/static tests make them potentially more useful than palpation tests for selected clinical purposes, such as discriminating between joint and muscle pain as well as monitoring symptoms course. Thus, findings from this investigation suggest that both tests should be included in the TMD diagnostic algorithms.

Studies have suggested that Research Diagnostic Criteria for Schizoaffective Disorder Bipolar type (RDC-SABP) might identify a more genetically homogenous subgroup of bipolar disorder. Aiming to identify loci associated with RDC-SABP, we have performed a replication study using independent RDC-SABP cases (n = 144) and controls (n = 6,559), focusing on the 10 loci that reached a p-value <10-5 for RDC-SABP in the Wellcome Trust Case Control Consortium (WTCCC) bipolar disorder sample. Combining the WTCCC and replication datasets by meta-analysis (combined RDC-SABP, n = 423, controls, n = 9,494), we observed genome-wide significant association at one SNP, rs2352974, located within the intron of the gene TRAIP on chromosome 3p21.31 (p-value, 4.37 × 10-8 ). This locus did not reach genome-wide significance in bipolar disorder or schizophrenia large Psychiatric Genomic Consortium datasets, suggesting that it may represent a relatively specific genetic risk for the bipolar subtype of schizoaffective disorder.

BACKGROUND: This study clinically evaluated the effect of botulinum toxin type A (BTX-A) in the temporomandibular disorder (TMD) treatment using Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD). METHODS: A total of 21 TMD patients were recruited to be treated with BTX-A injections on the bilateral masseter and temporalis muscles and were followed up by an oral and maxillofacial surgeon highly experienced in the TMD treatment. For each patient, diagnostic data gathering were conducted according to the RDC/TMD. Characteristic pain intensity, disability points, chronic pain grade, depression index, and grade of nonspecific physical symptoms were evaluated. Wilcoxon signed-rank test was applied for statistical analysis. RESULTS: The results showed that more than half of the participants (85.7 %) had parafunctional oral habits such as bruxism or clenching. In comparison between pre- and post-treatment results, graded pain score, characteristic pain intensity, disability points, chronic pain grade, and grade of nonspecific physical symptoms showed statistically significant differences after the BTX-A injection therapy (p < 0.05). Most patients experienced collective decrease in clinical manifestations of TMD including pain relief and improved masticatory functions after the treatment. CONCLUSIONS: Within the limitation of our study, BTX-A injections in masticatory musculatures of TMD patients could be considered as a useful option for controlling complex TMD and helping its associated symptoms.

Los Criterios Diagnósticos para la Investigación de los Trastornos Temporomandibulares (CDI/TTM) ofrecen un sistema estandarizado para evaluar la Disfunción Temporomandibular (DTM). Sin embargo, la validez del diagnóstico clínico obtenido con estos criterios al compararlo con el diagnóstico obtenido de las imágenes de Resonancia Magnética (RM) es controversial. El objetivo fue determinar la concordancia que existe entre la evaluación clínica realizada con los CDI/TTM e imágenes de RM de la articulación temporomandibular (ATM), de pacientes atendidos en la Clínica Integral del Adulto, de la Escuela de Odontología de la Universidad del Valle, en Cali, Colombia. Se evaluó clínicamente a 36 individuos, con edades comprendidas entre 18 y 60 años, utilizando los CDI/TTM y se les realizaron exámenes de RM. Las variables estudiadas fueron sexo, edad, signos y síntomas de la ATM, Posición Normal del Disco (PND), Desplazamiento Discal con Recaptura (DDCR) y Desplazamiento Discal Sin Recaptura (DDSR). Los datos obtenidos fueron sometidos a pruebas estadísticas para determinar el índice Kappa y características operativas de la prueba clínica. El Índice Kappa fue 0,53, con una concordancia entre las evaluaciones clínicas e imagenológicas moderada. De la población estudiada, 91,6% fue del sexo femenino, con 31 años como promedio de edad. El signo hallado con mayor frecuencia fue el ruido articular (77%) y el síntoma más frecuente fue el dolor facial (69%). La sensibilidad de los CDI/TTM para determinar la PND fue 0,52 y la especificidad 0,87; la sensibilidad para el DDCR fue 0,8780 y la especificidad 0,709; la sensibilidad para el DDSR fue 0,5714 y la especificidad 0,948. La DTM se presentó con mayor frecuencia en las mujeres, con edad promedio de 31 años. Los CDI/TTM pueden considerarse confiables, especialmente para el DDCR; sin embargo, tratamientos invasivos, permanentes o quirúrgicos, requerirían confirmación con un diagnóstico imagenológico para evitar falsos positivos.
The Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) offer a standardized system to clinically evaluate the most common subtypes of Temporomandibular Disorders (TMD). However, the validity of the clinical diagnose obtained with these criteria when compared with the diagnose obtained from the images of Magnetic Resonance (MR) is controversial. The objective of this study was to determine the concordance existing between the clinical evaluation obtained from the RDC/TMD and that obtained from MR images of the temporomandibular joint (TMJ) of patients attending the Clínica Integral del Adulto Clínica de ATM, of the Escuela de Odontología of the Universidad del Valle, Cali, Colombia. A population of 36 patients of both sexes, with ages between 18 and 60 years, were clinically evaluated with the RDC/TMD and MR. The variables considered were sex, age, signs and symptoms of the TMJ, Normal Disc Position (NDP), Disc Displacement with Reduction (DD-R) and Disc Displacement without Reduction (DD-NR). The data obtained were submitted to statistical tests to determine the Kappa Index and operative characteristics of the clinical evaluation. The Kappa Index obtained was 0.53, which shows that the concordance between the clinical and the imagenological evaluations is moderate. Of the total population studied, 91.6% were females, with 31 years as average age. The most frequent sign found was the joint sound (77%) and the most frequent symptom was facial pain (69%). The sensitivity of the RDC/TMD to determine NDP was 0.52 and the specificity 0.87; the sensitivity for the DD-R was 0.8780 and the specificity 0.709; the sensitivity for the DD-NR was 0.5714 and the specificity 0.948. The TMD were found most frequent in women, with average age of 31 years. The RDC/TMD can be considered reliable, especially for the DD-R; however, invasive, permanent or surgical treatments would require confirmation with imagenological diagnoses to avoid false positives.

The current Diagnostic and Statistical Manual of Mental Disorders (DSM)-5 arose from a tradition filled with haphazard science and politically driven choices. The nosology of modern psychiatry began with the German classifiers of the late 19th century, especially Emil Kraepelin. Psychoanalysis then blotted out the classificatory vision for the next half-century, and most of this European psychopathological science failed to cross the Atlantic. The DSM series was a homegrown American product, beginning with Medical 203 in 1945, then guided by psychoanalytic insights through DSM-I in 1952 and DSM-II in 1968. In 1980, DSM-III represented a massive "turning of the page" in nosology, and it had the effect of steering psychoanalysis toward the exit in psychiatry and the beginning of a reconciliation of psychiatry with the rest of medicine. With the advent of DSM-5, however, questions are starting to be asked about whether this massive venture is on the right track.
El actual DSM-5 (Manual Diagnóstico y Estadístico) surgió de una tradición llena de ciencia casual y opciones impulsadas políticamente. La nosología de la moderna psiquiatría comenzó con los clasificadores alemanes de finales del siglo XIX, en especial Emil Kraepelin. Posteriormente el psicoanálisis empañó la visión clasificatoria por el siguiente medio siglo, y la mayor parte de esta ciencia psicopatológica europea no logró cruzar el Atlántico. La serie de los DSM es un producto americano hecho en casa, que comenzó con Medical 203 en 1945, y luego fue orientado por concepciones psicoanalíticas a través del DSM-I en 1952 y el DSM-II en 1968. En 1980 el DSM-III representó una masiva "vuelta de página" en la nosología, encauzó el psicoanálisis hacia la salida de la psiquiatría y comenzó con la reconciliación de la psiquiatría con el resto de la medicina. Sin embargo; con la aparición del DSM-5 están surgiendo preguntas para ser respondidas acerca de si esta gran iniciativa está por el camino correcto.
L'actuel DSM-5 (Manuel diagnostique et statistique) provient d'une tradition nourrie de science peu méthodique et de choix politiques. La nosologie de la psychiatrie moderne a commencé avec les classificateurs allemands du XIXe siècle, en particulier Emile Kraepelin. Pendant la première moitié du siècle suivant, la psychanalyse a ensuite effacé la vision classificatrice et la plupart de cette science psychopathologique européenne n'a pas réussi à traverser l'Atlantique. La série des DSM est un produit américain autochtone, commençant avec le Medical 203 en 1945, puis guidée par des points de vue psychanalytiques du DSM-I en 1952 au DSM-II en 1968. En 1980, le DSM-III a permis de « tourner la page ¼ complètement en nosologie, en ayant pour effet de guider la psychanalyse vers la sortie en psychiatrie et de débuter une réconciliation entre la psychiatrie et le reste de la médecine. Cependant, l'avènement du DSM-5 remet en question la pertinence de la voie de cette gigantesque entreprise.

OBJECT: Idiopathic trigeminal neuralgia (iTN) is a neurological condition treated with pharmacotherapy or neurosurgery. There is a lack of comparative papers regarding the outcomes of neurosurgery in patients with iTN. The objective of this study was to investigate sensory thresholds and masticatory function in 78 patients with iTN who underwent microvascular decompression (MVD) or balloon compression (BC), and compare these treatments with carbamazepine and 30 untreated healthy controls. METHODS: The authors conducted a case-controlled longitudinal study. Patients were referred to 1 of 3 groups: MVD, BC, or carbamazepine. All patients were evaluated before and after treatment with a systematic protocol composed of a clinical orofacial questionnaire, Research Diagnostic Criteria for temporomandibular disorders, Helkimo indices, and a quantitative sensory-testing protocol (gustative, olfactory, cold, warm, touch, vibration, superficial, and deep pain thresholds). RESULTS: Both MVD and BC were effective at reducing pain intensity (p = 0.012) and carbamazepine doses (p < 0.001). Myofascial and articular complaints decreased in both groups (p < 0.001), but only the patients in the MVD group showed improvement in Helkimo indices (p < 0.003). Patients who underwent MVD also showed an increase in sweet (p = 0.014) and salty (p = 0.003) thresholds. The sour threshold decreased (p = 0.003) and cold and warm thresholds increased (p < 0.001) in patients after MVD and BC, but only the patients who underwent BC had an increase in touch threshold (p < 0.001). CONCLUSIONS: Microvascular decompression and BC resulted in a reduction in myofascial and jaw articular complaints, and the impact on masticatory function according to Helkimo indices was greater after BC than MVD. MVD resulted in more gustative alterations, and both procedures caused impairment in thermal thresholds (warm and cold). However, only BC also affected touch perception. The sensorial and motor deficits after BC need to be included as targets directly associated with the success of the surgery and need to be assessed and relieved as goals in the treatment of iTN.

In the U.S. the National Institute of Mental Health (NIMH), the main funder of mental health research in the world, has recently changed its funding model to promote a radically new perspective for mental health science. This bold, and for some controversial, initiative, termed the Research Diagnostic Criteria (or RDoC for short), intends to shift the focus of research, and eventually clinical practice, away from existing diagnostic categories, as recently updated in the DSM-5, towards 'new ways of classifying psychopathology based on dimensions of observable behavior and neurobiological measures.' This reorientation from discrete categorical disorder manifestations to underlying cross-cutting dimensions of individual functioning has generated considerable debate across the community of mental health researchers and clinicians (with strong views voiced both pro and con). Given its pivotal role in defining the research agenda globally, there is little doubt that this US science funding initiative will also have ramifications for researchers and clinicians worldwide. In this Editorial we focus specifically on the translational potential of the dimensional RDoC approach, properly extended to developmental models of early risk, in terms of its value as a potential driver of early intervention/prevention models; in the current issue of the JCPP this is exemplified by a number of papers thata address the mapping of underlying dimensions of core functioning to disorder risk, providing evidence for their potential predictive power as early markers of later disorder processes.

OBJECTIVE: The purpose of this study was to investigate the prevalence of temporomandibular disorders (TMD) in denture wearers and the association between prosthetic factors and this condition. BACKGROUND: There is no consensus about the relationship between prosthetic factors and TMD among denture wearers. MATERIALS AND METHODS: The sample was composed of 92 patients wearing both maxillary and mandibular complete dentures. The Research Diagnostic Criteria for TMD (RDC/TMD) were adopted for patient examination. Objective evaluation of denture quality was determined by analysis of retention and stability of mandibular denture, interocclusal distance, articulation and occlusion. Association between denture quality and TMD diagnosis was analysed using chi-square and Fisher's exact tests. RESULTS: 37.4% of the patients presented TMD. Denture quality was not significantly associated with the presence of TMD: mandibular retention (p = 0.466); mandibular stability (p = 0.466); interocclusal distance (p = 0.328); centric relation (p = 0.175); and balanced occlusion (p = 0.56). CONCLUSION: Within the scope of this case-controlled cross-sectional study, no robust association between prosthetic factors and TMD was found.
