    In the past, the ATM was mainly associated with the growth of the mandibular condyle. Many studies (on rats) showed the role of condylar cartilage in the growth response following stimulation by orthopedic appliances. From where, Class II dysmorphosis "orthopedic" treatments to grow the mandible; but this concept is discussed in the literature in the absence of fully conclusive results and especially since the contribution of orthognathic surgery. Currently, the operating concept is the mechanical stimulation and therefore the function will shape the ATM during growth and that, from an early age. Prevention of dysmorphoses must go through behavioral counseling to be adopted by parents from the birth of their child: to stimulate mandibular propulsion breastfeeding, then by a hard diet inducing an alternating unilateral chewing. Ignorance of the specificity of temporomandibular dysfunction (TMD) notably among teenagers has, in the past, left a doubt about the positive or negative role that could have orthodontic treatment on the TMJ. Currently, the best knowledge of TMJ and TMD provides a better therapeutic conduct: behavioral counseling especially for the girl hyperdivergente with small condyles, control of the condylar position, occlusal adjustments at the end of orthodontic treatment. The future of TMJ in relation with orthodontics is based on prevention, screening and deepening of our knowledge. The orthodontist will thus not make a treatment in patients at risk or will identify it and finish the treatment perfectly. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

    Though magnetic resonance (MRI) is a widely accepted standard for the assessment of patients with temporomandibular joint (TMJ) disorders, efforts to correlate symptoms to MRI findings have often given controversial results. Aim of this study was to investigate the correlation between TMJ pain and findings of contrast-enhanced MRI. Thirty-eight consecutive patients with TMJ dysfunction syndrome (study group) were examined with MRI. Protocol included T2 turbo spin-echo sequence, T1 spin-echo sequence, and T2 gradient-echo (acquired with closed jaw, at intermediate and maximal opening). Post-contrast phase was obtained through a fat sat 3D T1 gradient-echo sequence (VIBE). Post-contrast findings in the study group were matched with those obtained in a control group of 33 patients submitted to MRI of the paranasal sinuses. Statistically significant difference was found between condylar medullary bone enhancement in painful TMJ, in painless TMJ and control group. In addition the average thickness of joint soft tissue enhancement in painful TMJ was superior to painless TMJ (p < 0.0001) and to control group. On multivariate logistic regression analysis, the odds ratio that a painful TMJ showed disk displacement, osteoarthrosis, effusion and JST enhancement were 3.05, 3.18, 1.2 and 11.36, respectively. Though not histologically proven, TMJ enhancement could reflect the presence of inflammation in painful joints. Furthermore, the administration of contrast could be of help for the assessment of patients with orofacial pain, particularly when clinical exploration is insufficient to ascribe the pain to TMJ.

    Arthrosis of the temporomandibular joint (TMJ) is a noninfectious, noninflammatory condition characterized by joint pain, noise (clicking) and abnormal motion. It contains various disease processes, such as abnormalities in the menisci or masticating muscles, subluxation of the condyle and degenerative joint disease. Analysis of the morphology and dynamics of TMJ by means of imaging modalities has become highly advanced since the development of arthrography in the late 1970s. Magnetic resonance imaging (MRI) has become the modality of choice in the evaluation of TMJ owing to the development of surface coils. We retrospectively studied MRI and inferior joint compartment arthrography in the evaluation of TMJ disorders. Nineteen joints of 14 patients included 15 with internal derangement, two with osteoarthrosis and two normal joints. Sagittal MR images were routinely obtained in a resting position and in positions with the mouth half open, and also with the mouth fully open on balanced images. Although perforation of the menisci was difficult to evaluate, MRI and arthrography were equally useful in identifying the shape and position of the meniscus. However, MRI was more reliable in depicting TMJ abnormalities than arthrography. MRI is considered to be the modality of choice in screening arthrosis of TMJ, making the definitive diagnosis of internal derangement and monitoring conservative therapy for arthrosis. (author)

    Full Text Available Temporomandibular joint disorders may be caused by variety of factors; one of which is the posture of head and neck. However, this remains controversial and a subject of debate by experts. The objective of this study was to know whether there was a relation between temporomandibular disorders and the head and neck posture seen radiographically. Subjects were 40 dental students from University of Indonesia who met the inclusion criteria, selected through questionnaire, and subjective examination based on Helkimo’s dysfunction index. Then, lateral cephalometric radiographs were done to all subjects. In the radiogram, a horizontal line was made from the nasion point to the sella tursica, and a vertical line was drawn along the prominent bone of C1 – C5. The angle between the two lines was measured, and used to represent the head and neck posture. The design of the study was cross sectional. Based on statistical analysis, there was no significant relationship between the anamnestic dysfunction index as well as the clinical dysfunction index that represented the temporomandibular joint disorders and the posture of the head and neck seen radiographically.

    To evaluate of the relationship between the TMJ disorder and the vertical mandibular asymmetry, the author analyzed the differences between condylar heights, ramus heights and mandibular heights of both sides. All measurements were performed with a digital micrometer on the panoramic radiographs of 36 TMJ disorder patients and 30 normal control group. The differences were expressed in millimeters and percentage using the following formula; [(R-L)/(R+L)] X 100%. The results were as follows: 1. The condylar height difference was greater of in patient group (1.86±1.66 mm) than that of in control group (1.22±0.85 mm) (p<0.05). 2. The ramus height difference and ramus height ratio difference of patient group (4.52±3.70 mm, 4.39±3.49%) were greater than those of control group (2.64±2.13 mm, 2.46±2.02 %) (p<0.05, p<0.01). 3. The mandibular height difference and mandibular height ratio difference of patient group (4.32±3.52 mm, 3.59±2.81 %) were greater than those of contro group(2.57±2.46 mm, 2.01 (1.95%) (p<0.05). 4. The ratio difference in condylar height to ramus height and condylar height to mandibular height of patient group (5.01±4.13%, 3.36±2.88%) were greater than those of control group (2.33±1.78%, 1.90±1.40%) (p<0.01).

    Articular dysfunction of the TMJ with anterior displacement of the disc ('internal derangement') is an entity which has been separated from other types of the 'myofascial pain syndromes' and which can be treated conservatively or by surgery. Arthrography of the TMJ has contributed greatly to an understanding of normal and abnormal function and, in many cases, it can provide a diagnosis. On the basis of our experience with 80 investigations we discuss technical problems and the clinical indications. The indications for arthrography are in the pre-operative diagnosis, when clinical findings are uncertain, in order to demonstrate perforation, in order to confirm a suspected diagnosis and to assist in prosthetic treatment.

  15. Radiographic changes of TMJ components with an advancement of TMJ internal derangement

    2006-01-01

    Internal derangement (ID) of the temporomandibular joint (TMJ) relates to a mechanical and anatomical disturbance interfering with the smooth joint function. The ID usually develops in a benign and self-limiting fashion and does not always lead to progressing disorders. Radiographically visible degenerative changes occur with advancement of ID. It is thought that most of these changes closely correlate with the self-limiting nature of ID. In this report, a variety of radiographically visible degenerative changes were shown to develop with advancing ID. These changes, including a total and more anterior displacement of the TMJ disk, deviations in configuration of the TMJ disk, resorption of lateral pole of TMJ condyle, regression in horizontal size of the TMJ condyle, and flattening of the articular eminence, developed reflecting each other and might play an important role in an improvement of clinical signs and symptoms in the long run. It is also suggested that most of the acute and destructive radiographically visible degenerative changes were arrested or slowed in those patients whose symptoms and signs were successfully resolved or reduced.

    2003-04-01

    There are conflicting opinions about the frequency range of temporomandibular joint (TMJ) sounds. Some authors claim that the upper limit is about 650 Hz. The aim was to test the hypothesis that TMJ sounds may contain frequencies well above 650 Hz but that significant amounts of their energy are lost if the vibrations are recorded using contact sensors and/or travel far through the head tissues. Time-frequency distributions of 172 TMJ clickings (three subjects) were compared between recordings with one microphone in the ear canal and a skin contact transducer above the clicking joint and between recordings from two microphones, one in each ear canal. The energy peaks of the clickings recorded with a microphone in the ear canal on the clicking side were often well above 650 Hz and always in a significantly higher area (range 117-1922 Hz, P 375 Hz) or in microphone recordings from the opposite ear canal (range 141-703 Hz). Future studies are required to establish normative frequency range values of TMJ sounds but need methods also capable of recording the high frequency vibrations.

    Panoramic temporoman joint (TMJ) projection is one of the alternative methods of conventional radiography, such as transcranial projection, for diagnosing temporomandibular joint disorder. There have been a few reports describing the diagnostic ability of this method. We evaluated the diagnostic accuracy of detecting bone change with panoramic TMJ projection. Fifty TMJs in 25 patients were examined. All TMJs were examined by panoramic TMJ projection (Hyper XF) and limited cone-beam CT (3D Accuitomo FPD; 3DX). Two observers evaluated the presence of bone change in the TMJ region using panoramic TMJ projection. One other observer evaluated the limited cone-beam CT for the presence and the pattern of bone changes in the TMJ region as the gold standard. Panoramic TMJ findings were evaluated with regard to sensitivity, specificity, and accuracy. Sensitivity, specificity and accuracy of the panoramic TMJ projection were 0.86, 0.76, and 0.82, respectively. These results and those of previous reports on other radiographic methods for TMJ suggest that panoramic TMJ projection is a useful method of screening for bone change due to TMJ disorder. (author)

    Temporomandibular joint (TMJ) is a synovial joint that represents the junction of mandible with skull. TMJ and mastication muscles are affected by temporomandibular disorders (TMDs). During the last two decades the advances in imaging diagnostic of TMJ have greatly contributed to the assessment of the TMJ disorders. Labelled leukocytes with technetium- 99m hexamethyl propylene amine oxime ( 99m Tc-HMPAO) represent an efficient method that generates images based in physiological and/or biochemical changes related to inflammation. The aim of this study was to investigate the potential usefulness of technetium-99m labelled leukocytes scintigraphy in the diagnosis of TMJ inflammatory process applying a rabbit TMJ arthritis model. Arthritis was induced unilaterally with an intra-articular injection of ovalbumin in left ATM. On the contra-lateral side, the same dose of saline was injected. After five days, leukocytes were labeled with HMPAO and 99m Tc-HMPAO TMJ scintigraphic images were made. After twelve days a computed tomography was realized. Scintigraphic images obtained five days after induction of TMJ inflammation showed the localization of inflammatory process. The results were expressed as cpm of activity found in left ATM and contra-lateral side. Significant differences of activity were found between inflamed articulation and contra-lateral side (P = 0,0073). In conclusion, the method of leukocytes labeled with 99m Tc showed to be sensitive in detection of inflammatory disorders of TMJ and can be of great value in early diagnostic of these disorders.

    Presently, during the surgical treatment of the patients in maxillofacial surgery, one can use various medical implants. Moreover custom made implants are being used. Replacements may be fitted to the structure and shape of the human skull owing to CAD/CAM (custom aided design/manufacture) called customized implants. This study was aimed to report for the first time clinical material from which custom implants, using two different techniques, were manufactured to reconstruct the temporomandibular joint (TMJ). In this study, eleven patients with an average age of 54 years were included. All of the patients underwent TMJ reconstruction using direct metal laser sintering (DMLS) or computer numerical control milling (CNC) techniques for implant manufacture. Four of the eleven patients had a malignancy diagnosis, and seven had a benign diagnosis. Patients complained of hypomobility of the TMJ, facial asymmetry, pain and swelling of the preauricular region. Treatment included 7 CNC milled implants and 4 implants in DMLS. More metallic implant parts with a rough surface were associated with the DMLS technique. Post operational, uneventful healing was observed in all clinical cases during an average of 26.8 months of follow-up. Three months post-operation, facial nerve palsy, swallowing disturbances and pain were not observed. Infections, allergic reactions to materials and re-ankylosis were also not observed. Replacements received correct forms and functions owing to the CAM techniques. Post-operational maximal interincisal opening improved (p < 0.01) and was not significantly related to preoperational opening, age, sex, diagnosis or adjuvant radiotherapy. Considering both methods, the feature that differentiates the manufacture technique is the more subtractive surface finishing required for the DMLS implant than the CNC implant. Both techniques resulted the same clinical outcomes and can be used successfully in patients with neoplastic lesions and other TMJ disorders

    Full Text Available Many researchers had worked on TMD or CMD studies for the last 20 years, but the symptom remains unanswered to lead us into complete treatment. Orthodontic treatment is one of the non-invasive treatment carefully considered by the clinical to cure the TMD. The TMJ is the hinge that connects two main parts of human skull, the cranium and the mandible, through an articular disc that act as shock absorbers and prevent friction of the two. TMJ disorder usually causes unexplained and persistent facial pain in variety degrees, and a constellation of symptoms all related to the dysfunction of the TMJ.Generally, TMD patients present with a number of diagnoses within the TMD category and clinicians should understand each problem carefully. A clinician who believes that TMD is occlusion-related will treat the occlusion to eliminate the problem.

    Temporomandibular joint (TMJ) is a synovial joint that represents the junction of mandible with skull. TMJ and mastication muscles are affected by temporomandibular disorders (TMDs). During the last two decades the advances in imaging diagnostic of TMJ have greatly contributed to the assessment of the TMJ disorders. Labelled leukocytes with technetium- 99m hexamethyl propylene amine oxime ({sup 99m}Tc-HMPAO) represent an efficient method that generates images based in physiological and/or biochemical changes related to inflammation. The aim of this study was to investigate the potential usefulness of technetium-99m labelled leukocytes scintigraphy in the diagnosis of TMJ inflammatory process applying a rabbit TMJ arthritis model. Arthritis was induced unilaterally with an intra-articular injection of ovalbumin in left ATM. On the contra-lateral side, the same dose of saline was injected. After five days, leukocytes were labeled with HMPAO and {sup 99m}Tc-HMPAO TMJ scintigraphic images were made. After twelve days a computed tomography was realized. Scintigraphic images obtained five days after induction of TMJ inflammation showed the localization of inflammatory process. The results were expressed as cpm of activity found in left ATM and contra-lateral side. Significant differences of activity were found between inflamed articulation and contra-lateral side (P = 0,0073). In conclusion, the method of leukocytes labeled with {sup 99m}Tc showed to be sensitive in detection of inflammatory disorders of TMJ and can be of great value in early diagnostic of these disorders.

    Full Text Available Context, Aim, and Objectives: Diagnosis of temporomandibular joint (TMJ disc displacement with reduction (DDR is difficult. Literature combining different subjective parameters of TMJ function with an objective evaluation of TMJ function using joint vibration analysis (JVA is limited. Hence, the study was planned to diagnose temporomandibular disorder accurately, to do a subjective and objective evaluation of TMJ function, and to assess the effectiveness of different types of splint therapy over the conventional anterior repositioning appliance (ARA group. Design: Single-blind, randomized, comparative clinical trial conducted in thirty patients, 18–55 years of age, allocated to three groups, i.e., ARA conventional group, centric stabilization splint (CSS, and Soft splint (SS groups. Subjects and Methods: Preoperative values of comfortable mouth opening (CMO in mm, maximum mouth opening (MMO in mm, TMJ clicking and tenderness (grading 0–3, visual analog scale pain score (0–10 cm, and total energy (TE integral values of both TMJs using JVA were recorded. Postoperative values were taken at the time of delivery of splint at 1st, 2nd, 6th, and 10th week. Statistical Analysis and Results: Intergroup comparison – Kruskal–Wallis test showed no statistically significant difference in CMO, MMO, and TE values of right TMJs among three groups at any point. No significant difference was seen in TMJ clicking and tenderness among groups at any point of time except at 10 weeks and at 2 weeks, respectively, by Chi-square test. Intragroup comparison - Wilcoxon signed-rank test showed the significance of difference (P < 0.05* in postoperative visits for CMO, MMO, pain score, and TE values. Clinical effect size, extent, consistency, and percentage of cases showing improvement were maximum for CSS group. Conclusions: The study concludes that the use of JVA for diagnosis along with history and clinical examination increases the accuracy of the diagnosis of

    Temporomandibular joint (TMJ) disorders are a group of conditions that cause pain and dysfunction in the jaw joint and the muscles controlling jaw movement. However, diagnosis and treatment of these conditions remain controversial. To date, there is no single sign, symptom, or test that can clearly diagnose early stages of osteoarthritis (OA). Instead, the diagnosis is based on a consideration of several factors, including radiological evaluation. The current radiological diagnosis scores of TMJ pathology are subject to misdiagnosis. We believe these scores are limited by the acquisition procedures, such as oblique cuts of the CT and head positioning errors, and can lead to incorrect diagnoses of flattening of the head of the condyle, formation of osteophytes, or condylar pitting. This study consists of creating and validating a methodological framework to simulate defects in CBCT scans of known location and size, in order to create synthetic TMJ OA database. User-generated defects were created using a non-rigid deformation protocol in CBCT. All segmentation evaluation, surface distances and linear distances from the user-generated to the simulated defects showed our methodological framework to be very precise and within a voxel (0.5 mm) of magnitude. A TMJ OA synthetic database will be created next, and evaluated by expert radiologists, and this will serve to evaluate how sensitive the current radiological diagnosis tools are.

    Full Text Available Neurotoxins have existed on the earth from times immemorial. Old neurotoxic disorders were due to ingestion/ exposure of heavy metals and food like lathyrus sativus over a long period of time. The 20th Century with rapid industrialsation and expanding chemical and drug industry has spawned several new, hitherto unknown disorders. Old disorders continue to exist e.g. fluorosis, arsenicosis, lathyrism, manganism and lead neuropathy, along with new diseases like Minamata disease, subacute myelo optic neuropathy (SMON, MPTP-Parkinsonian syndorme, triorthcresyl phosphate (TOCP neuroparalytic disease, pesticide induced seizures, tremor and neuropathy, solvent encephalopthy, antipileptic drug foetal syndrome and excitotoxin induced behavioural disorders. Studies on pesticides Organochlorine and organophosphates, synthetic pyrethrins, solvents, heavy metals and substances abuse in the Indian context confirm the neurotoxic nature of many synthetic substances. Future problems envisaged are of concern to clinical neurologists as many of these neurotoxic disorders mimic syndromes of well known neurological disease. The new millenium poses a challenge to the clinician as newer compounds in industry, food, drugs and chemical war agents are being developed. Molecular genetics has advanced rapidly with release of the human genome map. Animal cloning and genetically modified plant products have entered the food chain. How safe are these new inventions for the central nervous system is a big question? India cannot afford disasters like Union Carbide′s Bhopal gas leak nor be a silent spectator to manipulative biotechnology. Unless it is proven beyond all doubt to be a safe innovation, Chemicals have to be cautiously introduced in our environment. To Study, ascertain and confirm safety or neurotoxicity is an exciting challenge for the neuroscientists of the 21st century.

    To evaluate the vascular anatomy of the temporomandibular joint (TMJ) and surrounding soft tissue non-invasively, we applied magnetic resonance (MR) angiography for delineating the arterial architecture around the TMJ. MR angiograms of the left and right TMJs in asymptomatic volunteers were obtained using 3D/Time-of-flight (TOF) (First Field Echo, TR/TE/FLIP=46 ms/6.8 ms/17 deg) with intravenous contrast. These MR angiograms were compared with experimental angiograms of human TMJ autopsy specimens in order to identify each of the branches of the arteries on the MR angiograms. This study enabled the depiction by MR angiography of arterial vessels around the TMJ region to some degree. In conclusion, MR angiography appears promising as a non-invasive tool to evaluate the vascular anatomy of the TMJ. (author)

    Bipolar disorder refers to a group of affective disorders, which together are characterised by depressive and manic or hypomanic episodes. These disorders include: bipolar disorder type I (depressive and manic episodes: this disorder can be diagnosed on the basis of one manic episode); bipolar disorder type II (depressive and hypomanic episodes); cyclothymic disorder (hypomanic and depressive symptoms that do not meet criteria for depressive episodes); and bipolar disorder not otherwise specified (depressive and hypomanic-like symptoms that do not meet the diagnostic criteria for any of the aforementioned disorders). Bipolar disorder type II is especially difficult to diagnose accurately because of the difficulty in differentiation of this disorder from recurrent unipolar depression (recurrent depressive episodes) in depressed patients. The identification of objective biomarkers that represent pathophysiologic processes that differ between bipolar disorder and unipolar depression can both inform bipolar disorder diagnosis and provide biological targets for the development of new and personalised treatments. Neuroimaging studies could help the identification of biomarkers that differentiate bipolar disorder from unipolar depression, but the problem in detection of a clear boundary between these disorders suggests that they might be better represented as a continuum of affective disorders. Innovative combinations of neuroimaging and pattern recognition approaches can identify individual patterns of neural structure and function that accurately ascertain where a patient might lie on a behavioural scale. Ultimately, an integrative approach, with several biological measurements using different scales, could yield patterns of biomarkers (biosignatures) to help identify biological targets for personalised and new treatments for all affective disorders.

    Full Text Available Orthognathic surgery may affect or cause temporomandibular joint (TMJ complaints. This study evaluated the need for TMJ surgery after orthognathic surgery.A retrospective cohort study was carried out on 630 consecutive patients undergoing at least a Le Fort I or bilateral sagittal split osteotomy (BSSO. The mean follow-up time was 2,3 years. Clinical, surgical and radiographic findings were collected.Ten of the 630 patients (1.6% had additional arthroscopic TMJ-surgery in one (9 or in both (1 joints because of internal derangement, resistant to conventional therapy. Only 4/10 patients had successful outcomes following arthroscopic surgery. One patient with unsuccessful outcome required multiple additional open TMJ-surgeries, all remaining ineffective to relieve pain and restricted mouth opening. If arthroscopy failed to relieve symptoms (5/10 patients, further conservative management was opted. Arthroscopy seemed effective mainly in patients without pre-existing TMJ complaints.A further five of the 630 patients (0.8% required more treatment because of bilateral postoperative condylar resorption, but none of them required TMJ-surgery.In contrast to patients with bilateral condylar resorption where the skeletal relapse remained the issue of concern, patients with internal derangement/osteoarthrosis exhibited major occlusal changes in one patient only (1/10, leaving the TMJ complaints as the main concern.

    Purpose. To evaluate the effectiveness of diagnostic and interventional radiological techniques for neoplastic lesions of the temporomandibular joint (TMJ). Material and methods. Modern diagnosis of the TMJ is based on the clinical use of conventional X-ray techniques, computed tomography (CT), magnetic resonance imaging (MRI) and interventional techniques like biopsies, vascular occlusion and ablation. Results. Conventional X-ray still forms the basic diagnostic procedure applied in open and closed mouth position. CT improves the diagnostic information and serves as the standard diagnostical instrument for cartaliganeous or osseous neoplastic lesions. MRI evaluates soft tissue infiltration in multiplanar techniques and high spatial resolution. Interventional vascular and ablative techniques improve the treatment of neoplastic disorders. (orig.)

    Temporomandibular disorders (TMDs) represent a group of painful conditions involving the muscles of mastication and the temporomandibular joint (TMJ) that frequently encountered in general clinical practice. This study is designed to assess the utility of vacuum pressed silicon sheet as a bite raising appliance in the management of TMJ dysfunction syndrome. The patients for this study were selected from those with the chief complaint of TMJ disorder. Out of 200 patients, 104 patients were diagnosed with subluxation and 96 patients were diagnosed with internal derangement of temporomandibular joint. All the reported cases were managed conservatively with physiotherapy and muscle relaxant therapy for one week period and followed with silicon bite raising appliance over both the arches in the subsequent period. All the patients had pain relief within six months duration as graded over verbal analog scale. ANOVA scale was used for comparision of VAS scores. The use of vacuum pressed bite raising appliance in the management of TMJ disorder was found to be satisfactorily effective in alleviation of pain symptom in our study group.

    Introduction Laser light Electromagnetic energy has some typical properties for discussions on laser irradiation abilities to control the acute and chronic disorders in TMJ. Material and Methods During the last six years we have been completed well controlled clinical trials based on the criteria of the American Academy of orofacial pain. The study over the 600 patients (300 women and 300 men), mean age of 47 years have been developed. Patients have been selected on the main clinical sign of TMJ pain and have been divided into four main groups according to the type of PDT method. Based on the action spectra, various wavelengths have been used for TMJ Photodynamic Therapy. Constant dose and time of exposition, as well as various range of frequencies have been applied. In this way the Laser biostimulation response has been directly proportional to the total energy dose, depending of light intensity. Physiological and clinical effects of the followed "active regions"- 660 - 680, 760 - 780, 810 - 830 and 904 - 987 nm have been valued by method of comparative analysis. Methods applied: LLLT - TENS - red surface laser acupuncture (LA), PIPBM - LA, Laser bioenergetics approach, Complex therapeutic program (CTP). Results evaluation will be demonstrated by comparative digital ortopantomograph analysis, EEG brain maps, VAS, a metric analysis of the level of the maximum active Mandible opening and EPST through electrophysiological signal evaluation of the patient's body.

  20. Mesenchymal Stem Cells for Cartilage Regeneration of TMJ Osteoarthritis

    2017-01-01

    Full Text Available Temporomandibular joint osteoarthritis (TMJ OA is a degenerative disease, characterized by progressive cartilage degradation, subchondral bone remodeling, synovitis, and chronic pain. Due to the limited self-healing capacity in condylar cartilage, traditional clinical treatments have limited symptom-modifying and structure-modifying effects to restore impaired cartilage as well as other TMJ tissues. In recent years, stem cell-based therapy has raised much attention as an alternative approach towards tissue repair and regeneration. Mesenchymal stem cells (MSCs, derived from the bone marrow, synovium, and even umbilical cord, play a role as seed cells for the cartilage regeneration of TMJ OA. MSCs possess multilineage differentiation potential, including chondrogenic differentiation as well as osteogenic differentiation. In addition, the trophic modulations of MSCs exert anti-inflammatory and immunomodulatory effects under aberrant conditions. Furthermore, MSCs combined with appropriate scaffolds can form cartilaginous or even osseous compartments to repair damaged tissue and impaired function of TMJ. In this review, we will briefly discuss the pathogenesis of cartilage degeneration in TMJ OA and emphasize the potential sources of MSCs and novel approaches for the cartilage regeneration of TMJ OA, particularly focusing on the MSC-based therapy and tissue engineering.

    Treatments for patients suffering from severe temporomandibular joint (TMJ) dysfunction are limited, motivating the development of strategies for tissue regeneration. In this study, co-cultures of fibrochondrocytes (FCs) and articular chondrocytes (ACs) were seeded in agarose wells, and supplemented with growth factors, to engineer tissue with biomechanical properties and extracellular matrix composition similar to native TMJ fibrocartilage. In the first phase, growth factors were applied alone and in combination, in the presence or absence of serum, while in the second phase, the best overall treatment was applied at intermittent dosing. Continuous treatment of AC/FC co-cultures with TGF-β1 in serum-free medium resulted in constructs with glycosaminoglycan/wet weight ratios (12.2%), instantaneous compressive moduli (790 kPa), relaxed compressive moduli (120 kPa) and Young's moduli (1.87 MPa) that overlap with native TMJ disc values. Among co-culture groups, TGF-β1 treatment increased collagen deposition ∼20%, compressive stiffness ∼130% and Young's modulus ∼170% relative to controls without growth factor. Serum supplementation, though generally detrimental to functional properties, was identified as a powerful mediator of FC construct morphology. Finally, both intermittent and continuous TGF-β1 treatment showed positive effects, though continuous treatment resulted in greater enhancement of construct functional properties. This work proposes a strategy for regeneration of TMJ fibrocartilage and its future application will be realized through translation of these findings to clinically viable cell sources.

    Bone scan is a very sensitive diagnostic imaging test for detecting bone and joint disorders. So it might be useful in the diagnosis of temporomandibular disorders of the joint origin. Thus, the effectiveness of bone scan for detecting temporomandibular joint(TMJ) diseases and differentiating the TMJ disc displacement from the TMJ arthritis was evaluated. Bone scan was done in 21 patients with TMJ disc displacement (I3 unilaterally affected, 8 bilaterally affected), 26 patients with TMJ arthritis (23 unilateral, 3 bilateral), and 39 volunteers with no signs, symptoms, or history of TMJ disease TMJ simple uptake rate(SUR) and difference of both TMJ SUR were calculated from the 100,000 count lateral image of head and neck region in 99m Tc MDP bone scan. Transcranial and panorama X-ray examination was also done in all patients. TMJ SUR(%) were 1.67 ±0.606 in TMJs affected with arthritis, 1.350±0.351 in TMJs affected with disc displacement, and 1.084±0.172 in TMJs of controls Significant differences were demonstrated among them(p mean+2SD of controls) in unilateral TMJ arthritis patients were significantly higher than those in patients with unilateral TMJ disc displacement(69.6% and 87% vs 23.1% and 23%). Conclusively, bone scan may help to detect TMJ disease and differentiate TMJ disc displacement from TMJ arthritis.

    Competing theories on the etiology and treatment of chronic tic disorders and Tourette syndrome have long made the search for efficacious intervention more challenging for patients and families seeking to reduce functional impairment related to tic symptoms. These symptoms were historically posited to be either psychological in origin, leading to the long tradition of psychoanalytic psychotherapy for tics, or biological in nature, particularly since the advent of successful treatments using neuroleptic medications. Current thinking about the phenomenology of tic disorders comes from growing empirical evidence as well as advances in neuroscience and genetics research and reveals a biological vulnerability that is exacerbated by physiological arousal related to environmental or interpersonal stress. This manuscript summarizes the evolution of this knowledge base and describes current best-practice recommendations for patients, families, and clinicians. © 2013 New York Academy of Sciences.

    Objective To describe CT findings in dogs and cats with temporomandibular joint (TMJ) disorders. Design Retrospective case-series. Animals 41 dogs and 17 cats. Procedures Medical records and CT images of the skull were reviewed for dogs and cats that were examined at a dentistry and oral surgery specialty practice between 2006 and 2011. Results Of 142 dogs and 42 cats evaluated, 41 dogs and 17 cats had CT findings consistent with a TMJ disorder. In dogs, the most common TMJ disorder was osteoarthritis; however, in most cases, there were other TMJ disorders present in addition to osteoarthritis. Osteoarthritis was more frequently identified at the medial aspect rather than the lateral aspect of the TMJ, whereas the frequency of osteoarthritic involvement of the dorsal and ventral compartments did not differ significantly. In cats, fractures were the most common TMJ disorder, followed by osteoarthritis. Clinical signs were observed in all dogs and cats with TMJ fractures, dysplasia, ankylosis, luxation, and tumors; however, only 4 of 15 dogs and 2 of 4 cats with osteoarthritis alone had clinical signs. Conclusions and Clinical Relevance Results indicated that TMJ disorders are frequently present in combination. Osteoarthritis was the most common TMJ disorder in dogs and the second most common TMJ disorder in cats. Computed tomography should be considered as a tool for the diagnosis of TMJ disorders in dogs and cats with suspected orofacial disorders and pain. PMID:23234284

    Attributing dysfunction of the temporomandibular joint (TMJ) to whiplash injury is a difficult problem to solve. TMJ disorders do not seem to be secondary to direct articular trauma but rather caused by a postural disorder of the cervical spine. Occlusal disorders and stress further complicate the picture. Four clinical cases illustrate a new hypothetical approach.

    2017-01-01

    This study reviewed the dental literature in order to determine the association of bone marrow edema with osteoarthritis and temporomandibular joint (TMJ) internal derangement disorders. A literature search was performed using electronic databases PubMed/Medline (National Library of Medicine, Bethesda, Maryland) and Cochrane for articles published during the last 15 years (January 2000-December 2014). A predetermined inclusion and exclusion criteria were used for filtering the scientific papers. Research articles fulfilling the basic inclusion criteria were included in the review. The reviewed studies showed that bone marrow edema is found in painful joints with osteoarthritis in a majority of cases. A few cases with no pain or significant degenerative changes are reported to have a bone marrow edema pattern as well. Bone marrow edema, increased fluid level, and pain are associated with osteoarthritis in the majority of patients reporting TMJ arthritis. Degenerative and disc displacement conditions are multifactorial and require further investigations. Magnetic resonance imaging can be employed to detect bone marrow edema even in the absence of pain and clinical symptoms in the patients of internal derangements.

    The imaging investigation of the internal derangements of temporomandibular joint (TMJ) has been recently enriched with state of the art tools, such as CT and MRI. However these equipments are not widely available in our country. In addition, some lesions such as perforation of the MJ meniscus, are not demonstrated by either one of these methods, been fairly easily showed by arthorography. The purpose of this paper is to show our experience with 386 arthrograms performed in 193 patients. Our results are compatible with those of the literature. In the last group of 176 patients, we have abandonned the local anesthesia procedure, with good advantages. Arthrography is a very usefull method in the evaluation of TMJ and should be more used in our country. (author)

    Articular dysfunction of the TMJ with anterior displacement of the disc ('internal derangement') is an entity which has been separated from other types of the 'myofascial pain syndromes' and which can be treated conservatively or by surgery. Arthrography of the TMJ has contributed greatly to an understanding of normal and abnormal function and, in many cases, it can provide a diagnosis. On the basis of our experience with 80 investigations we discuss technical problems and the clinical indications. The indications for arthrography are in the pre-operative diagnosis, when clinical findings are uncertain, in order to demonstrate perforation, in order to confirm a suspected diagnosis and to assist in prosthetic treatment.

    Tinnitus is frequently associated with temporomandibular joint (TMJ) dysfunction. However, the nature of the relationship is not fully understood. Here the authors compared 30 patients with a confirmed diagnosis of temporomandibular joint dysfunction and tinnitus to a group of 61 patients with tinnitus but without any subjective complaints of TMJ dysfunction with respect to clinical and demographic characteristics. Case-control study. Tertiary referral center. Tinnitus patients with and without TMJ dysfunction presenting at the Department of Prosthetic Dentistry and th: Tinnitus Clinic at the University of Regensburg. Tinnitus patients with TMJ disorder had better hearing function (P neck movements (P = .001). Classical risk factors for tinnitus (age, male gender, hearing loss) are less relevant in tinnitus patients with TMJ disorder, suggesting a causal role of TMJ pathology in the generation and maintenance of tinnitus. Based on this finding, treatment of TMJ disorder may represent a causally oriented treatment strategy for tinnitus.

    Temporomandibular joint (TMJ) forms an integral functional part of stomatognathic system. Position, shape, structure and function of teeth have an influence on the proper functioning and health of TMJ. But a problem associated with TMJ is often neglected, and treatment for it is mostly restricted to palliative therapy. A proper understanding of the underlying cause of temporomandibular joint disorder (TMD) is necessary to device a proper treatment plan. Etiology of TMDs varies from idiopathic...

    2007-05-01

    In this article, the current state of our knowledge of pragmatic disorders in adults with language impairment is assessed. A brief historical background of clinical pragmatics is presented, and the place of adult language pathology within the development of this field is discussed. A comprehensive review is undertaken of pragmatic deficits in adults with language impairments of diverse etiologies. Specifically, pragmatic deficits are examined in adults with left-hemisphere damage, often resulting in aphasia, and in adults with right-hemisphere damage, traumatic brain injury, schizophrenia, and neurodegenerative disorders (principally, Alzheimer's disease). Although many pragmatic phenomena have been examined in these clinical populations, studies have also tended to neglect important areas of pragmatic functioning in adults with these disorders. Several such areas are identified within a wider discussion of how researchers and clinicians can best pursue future investigations of pragmatics in adults with language impairment.

    Anxiety is one of the most widely observed and extensively studied psychological concomitants of stuttering. Research conducted prior to the turn of the century produced evidence of heightened anxiety in people who stutter, yet findings were inconsistent and ambiguous. Failure to detect a clear and systematic relationship between anxiety and stuttering was attributed to methodological flaws, including use of small sample sizes and unidimensional measures of anxiety. More recent research, however, has generated far less equivocal findings when using social anxiety questionnaires and psychiatric diagnostic assessments in larger samples of people who stutter. In particular, a growing body of research has demonstrated an alarmingly high rate of social anxiety disorder among adults who stutter. Social anxiety disorder is a prevalent and chronic anxiety disorder characterised by significant fear of humiliation, embarrassment, and negative evaluation in social or performance-based situations. In light of the debilitating nature of social anxiety disorder, and the impact of stuttering on quality of life and personal functioning, collaboration between speech pathologists and psychologists is required to develop and implement comprehensive assessment and treatment programmes for social anxiety among people who stutter. This comprehensive approach has the potential to improve quality of life and engagement in everyday activities for people who stutter. Determining the prevalence of social anxiety disorder among children and adolescents who stutter is a critical line of future research. Further studies are also required to confirm the efficacy of Cognitive Behaviour Therapy in treating social anxiety disorder in stuttering. The reader will be able to: (a) describe the nature and course of social anxiety disorder; (b) outline previous research regarding anxiety and stuttering, including features of social anxiety disorder; (c) summarise research findings regarding the

    Full Text Available Temporomandibular disorders (TMDs have the highest prevalence in women of reproductive age. The role of estrogen in TMDs and especially in TMDs related pain is not fully elucidated. Voltage-gated sodium channel 1.7 (Nav1.7 plays a prominent role in pain perception and Nav1.7 in trigeminal ganglion (TG is involved in the hyperalgesia of inflamed Temporomandibular joint (TMJ. Whether estrogen could upregulate trigeminal ganglionic Nav1.7 expression to enhance hyperalgesia of inflamed TMJ remains to be explored.Estrous cycle and plasma levels of 17β-estradiol in female rats were evaluated with vaginal smear and enzyme linked immunosorbent assay, respectively. Female rats were ovariectomized and treated with 17β-estradiol at 0 μg, 20 μg and 80 μg, respectively, for 10 days. TMJ inflammation was induced using complete Freund's adjuvant. Head withdrawal thresholds and food intake were measured to evaluate the TMJ nociceptive responses. The expression of Nav1.7 in TG was examined using real-time PCR and western blot. The activity of Nav1.7 promoter was examined using luciferase reporter assay. The locations of estrogen receptors (ERα and ERβ, the G protein coupled estrogen receptor (GPR30, and Nav1.7 in TG were examined using immunohistofluorescence.Upregulation of Nav1.7 in TG and decrease in head withdrawal threshold were observed with the highest plasma 17β-estradiol in the proestrus of female rats. Ovariectomized rats treated with 80 μg 17β-estradiol showed upregulation of Nav1.7 in TG and decrease in head withdrawal threshold as compared with that of the control or ovariectomized rats treated with 0 μg or 20 μg. Moreover, 17β-estradiol dose-dependently potentiated TMJ inflammation-induced upregulation of Nav1.7 in TG and also enhanced TMJ inflammation-induced decrease of head withdrawal threshold in ovariectomized rats. In addition, the estrogen receptor antagonist, ICI 182,780, partially blocked the 17β-estradiol effect on Nav1

    Using 12 human fetuses, histological development and changes in connective fiber structure and fine vascular patterns have been investigated in various fetal gestational stages by light and scanning electron microscopy. The main arterial supply of the articular disc was from the bilaminar region and pterygoideus lateralis muscle. The vascular network on the disc surface was related with fluid secretion. When the bilaminar region was compressed, it caused ischemia and fibrosis as the main pathological changes in TMJ derangement. A decrease in fluid from blood vessels might occur in TMJ degeneration. Collagen fibers in the disc passed mainly anteroposteriorly. In the anterior and posterior bands, muscular tendon fibers came from the pterygoideus lateralis muscle and superior stratum of the bilaminar region. In the posterior band three-dimensional structures of collagen fibers suitable for load bearing were observed. The compass network and process on the disc showed the normal structure that is formed gradually and has functions including dispersion, pressure bearing, friction-proofing and storage of the synovial fluid. Attachments of the disc were suitable for disc function. Large elastic fibers in the posterolateral part of the superior stratum of the bilaminar region may be antagonistic to the upper head of the pterygoideus lateralis muscle fibers passing medioanteriorly, indicating that this antagonism is available for disc function.

    Classification is the cornerstone of clinical diagnostic practice and research. However, the extant psychiatric classification systems are not well supported by research evidence. In particular, extensive comorbidity among putatively distinct disorders flags an urgent need for fundamental changes in how we conceptualize psychopathology. Over the past decade, research has coalesced on an empirically based model that suggests many common mental disorders are structured according to two correlated latent dimensions: internalizing and externalizing. We review and discuss the development of a dimensional-spectrum model which organizes mental disorders in an empirically based manner. We also touch upon changes in the DSM-5 and put forward recommendations for future research endeavors. Our review highlights substantial empirical support for the empirically based internalizing-externalizing model of psychopathology, which provides a parsimonious means of addressing comorbidity. As future research goals, we suggest that the field would benefit from: expanding the meta-structure of psychopathology to include additional disorders, development of empirically based thresholds, inclusion of a developmental perspective, and intertwining genomic and neuroscience dimensions with the empirical structure of psychopathology.

    2001-01-01

    To investigate bone and disc configuration on MR images in internal derangement related to age. MR images of 150 TMJs in 107 patients were analyzed to determine the morphologic changes. Two groups were distinguished to be correlated with age. Group 1 consisted of TMJs that were diagnosed as having anterior disc displacement with reduction (ADDwR), and Group 2 consisted of TMJs that were diagnosed as having anterior disc displacement without reduction (ADDwR). We assessed the configuration of the articular disc, degree of anterior disc displacement, and osseous changes of TMJs. The third decade (83 of 150 joints) was most frequent in this study. In the ADDwR group biconcave disc was most frequent at all ages except fifth decade, but in the ADDwoR group deformed discs was most frequent at third and forth decades. In the ADDwR group slightly displaced discs was most frequent at all ages, but in the ADDwoR group severely displaced discs was most frequent at second decade, and the degree of disc displacement was increased with aging over 30 years of age. TM joints showed osseous changes in 17% of the ADDwR group, and in 30% of the ADDwoR group. MR findings of osseous changes of the TMJ were not found to be significantly correlated with age. The prevalence of deformation of disc, displacement of disc, and osseous changes of TMJ was higher in the ADDwoR group than in the ADDwR group. MR findings of disc configuration and degree of disc displacement were found to be correlated with age

    Background: Temporomandibular joints (TMJ) are frequently involved in children with juvenile idiopathic arthritis (JIA), and gadolinium-enhanced magnetic resonance imaging (MRI) is the only modality for an early diagnosis. However, only very few data exist on the appearance of contrast-enhanced MRI of normal juvenile TMJ. Purpose: To define the spectrum of normal MRI findings of juvenile TMJ, and to assess a possible overlap with findings typical for active synovitis in JIA. Material and Methods: 96 children (192 TMJ), 51 boys and 45 girls with a median age of 7.8 years (range 3-13 years), underwent a head MRI. The presence of autoimmune disease, including JIA, was excluded via chart history, available laboratory findings, and the absence of known typical pathological MRI changes (degree of synovial enhancement, hyperintense signal on T2-weighted images in the synovia or bone marrow, and morphologic changes of the mandibular condyle) of the TMJ affected by JIA. Results: In 90 (94%) children, the TMJ showed no MRI abnormalities compatible with arthritis. In three children (3%), the only abnormal MRI finding was a small bilateral joint effusion. A further three children (3%) had a mild synovial enhancement seen on both axial and coronal MR planes in one child and only in the axial plane in the other two children. Signal hyperintensity on T2-weighted images and other corresponding characteristics of TMJ inflammation were lacking in all these six patients. Conclusion: The vast majority of juvenile TMJ in non-rheumatic children shows no MRI abnormalities. Exceptions, including a discrete enhancement of the synovial membrane (3%) or small joint effusions (3%), can occur in a minority of patients, but none of them are accompanied by other signs of inflammation or morphological changes of the TMJ

    Temporomandibular joint (TMJ) inflammation is a potential risk factor of osteoarthritis (OA) but the detailed degenerative changes in the inflamed TMJ remain unclear. In this study, we evaluated the changes of condylar cartilage and subchondral bone in rat inflamed TMJ induced by Freund's complete adjuvant (CFA). Articular cavity was injected with CFA and the TMJ samples were collected 1, 2, 3, and 4-week post-injection. Hematoxylin & Eosin (H&E) staining, toluidine blue (TB) staining, Safranin O (S.O) staining, Masson trichrome staining and micro-CT were used to assess TMJ degeneration during inflammation. Osteoclast and osteoblast activities were analyzed by tartrate-resistant acid phosphatase (TRAP) staining and osteocalcin (OCN) immunohistochemistry staining respectively. The expression of receptor activator of NF-kB ligand (RANKL) and osteoprotegerin (OPG) in condylar cartilage and subchondral bone was also evaluated through immunohistochemistry and RANKL/OPG ratio was evaluated. Reduced cartilage thickness, decreased number of chondrocytes, and down-regulated proteoglycan expression were observed in the condylar cartilage in the inflamed TMJ. Enhanced osteoclast activity, and expanded bone marrow cavity were reached the peak in the 2-week after CFA-injection. Meanwhile the RANKL/OPG ratio in the cartilage and subchondral bone also increased in the 2-week CFA-injection. Immature, unmineralized new bones with irregular trabecular bone structure, atypical condylar shape, up-regulated OCN expression, and decreased bone mineral density (BMD) were found in the inflamed TMJ. The time-dependent degeneration manner of TMJ cartilage and subchondral bone was found in CFA-induced arthritis rat model. The degeneration in the TMJ with inflammation might be a risk factor and should be concerned.

    Full Text Available This study included 30 patients with diagnosed rheumatoid arthritis (RA and 30 test subjects without RA (control group. The objective of the study was to examine both groups for the presence of temporomandibular disorders (TMD and morphological changes of the temporomandibular joint (TMJ. All individuals were examined using a systematic detailed clinical TMD examination as well as magnetic resonance imaging (MRI. The clinical TMD examination yielded significant differences between the RA patients and the control group concerning crepitus of the TMJ, and palpation tenderness of the masticatory muscles as well as the unassisted mandibular opening. The evaluation of the MRI images for the RA group showed significantly more frequent deformations of the condyle, osteophyte formations and erosions in the condylar compacta, and degenerative changes in the spongiosa. Increased intra-articular accumulation of synovial liquid and signs of inflammatory changes of the spongiosa were only found in the RA group. Statistical analysis showed a significant correlation between crepitus and specific osteoarthrotic changes (MRI, respectively, and between crepitus and a complete anterior disk displacement without reduction (MRI. The duration of the RA disease correlated neither with the anamnestic and clinical dysfunction index by Helkimo nor with RA-specific MRI findings.

    Purpose. To evaluate the effectiveness of diagnostic and interventional radiological techniques for neoplastic lesions of the temporomandibular joint (TMJ). Material and methods. Modern diagnosis of the TMJ is based on the clinical use of conventional X-ray techniques, computed tomography (CT), magnetic resonance imaging (MRI) and interventional techniques like biopsies, vascular occlusion and ablation. Results. Conventional X-ray still forms the basic diagnostic procedure applied in open and closed mouth position. CT improves the diagnostic information and serves as the standard diagnostical instrument for cartaliganeous or osseous neoplastic lesions. MRI evaluates soft tissue infiltration in multiplanar techniques and high spatial resolution. Interventional vascular and ablative techniques improve the treatment of neoplastic disorders. (orig.)

    Objective In order to understand the conflicting information on temporomandibular joint (TMJ) pathophysiologic responses after mandibular advancement surgery, an overview of the literature was proposed with a focus on certain risk factors. Methods A literature search was carried out in the Cochrane, PubMed, Scopus and Web of Science databases in the period from January 1980 through March 2013. Various combinations of keywords related to TMJ changes [disc displacement, arthralgia, condylar resorption (CR)] and aspects of surgical intervention (fixation technique, amount of advancement) were used. A hand search of these papers was also carried out to identify additional articles. Results A total of 148 articles were considered for this overview and, although methodological troubles were common, this review identified relevant findings which the practitioner can take into consideration during treatment planning: 1- Surgery was unable to influence TMJ with preexisting displaced disc and crepitus; 2- Clicking and arthralgia were not predictable after surgery, although there was greater likelihood of improvement rather than deterioration; 3- The amount of mandibular advancement and counterclockwise rotation, and the rigidity of the fixation technique seemed to influence TMJ position and health; 4- The risk of CR increased, especially in identified high-risk cases. Conclusions Young adult females with mandibular retrognathism and increased mandibular plane angle are susceptible to painful TMJ, and are subject to less improvement after surgery and prone to CR. Furthermore, thorough evidenced-based studies are required to understand the response of the TMJ after mandibular advancement surgery. PMID:24626243

    The present study was designed to investigate the elastic modulus of human temporomandibular joint (TMJ) disk under tension and its influences on TMJ loading. Seven human TMJ disks served as specimens. Continuous tensile stress was applied to each specimen, and the elastic moduli of human TMJ disks were calculated at 2% strain. Furthermore, using a three-dimensional finite element model of the mandible including the TMJ, changes in the TMJ stresses during clenching were evaluated in association of varying elastic moduli of the articular disk determined by the tensile tests. The elastic moduli at 2% strain varied from 27.1 to 65.2 MPa with a mean of 47.1 MPa. A significant correlation was found between the elastic moduli and age (P elastic moduli of the TMJ disk was varied from 25 to 65 MPa. In the TMJ disk, shear stresses in all the areas became larger with greater stiffness. In conclusion, it is shown that the elastic modulus of human TMJ disk is increased with age and that higher stiffness of the disk exerts substantial influences on mechanical loading for the TMJ structures.

    To compare temporomandibular joint (TMJ) condylar cartilage cells in vitro to hyaline cartilage cells cultured in a three-dimensional (3D) environment for tissue engineering of mandibular condylar cartilage. Mandibular condylar cartilage and hyaline cartilage cells were harvested from pigs and cultured for 6 weeks in polyglycolic acid (PGA) scaffolds. Both types of cells were treated with glucosamine sulfate (0.4 mM), insulin-like growth factor-I (IGF-I) (100 ng/ml) and their combination. At weeks 0 and 6, cell number, glycosaminoglycan (GAG) and collagen content were determined, types I and II collagen were visualized by immunohistochemistry and GAGs were visualized by histology. Hyaline cartilage cells produced from half an order to a full order of magnitude more GAGs and collagen than mandibular condylar cartilage cells in 3D culture. IGF-I was a highly effective signal for biosynthesis with hyaline cartilage cells, while glucosamine sulfate decreased cell proliferation and biosynthesis with both types of cells. In vitro culture of TMJ condylar cartilage cells produced a fibrous tissue with predominantly type I collagen, while hyaline cartilage cells formed a fibrocartilage-like tissue with types I and II collagen. The combination of IGF and glucosamine had a synergistic effect on maintaining the phenotype of TMJ condylar cells to generate both types I and II collagen. Given the superior biosynthetic activity by hyaline cartilage cells and the practical surgical limitations of harvesting cells from the TMJ of a patient requiring TMJ reconstruction, cartilage cells from elsewhere in the body may be a potentially better alternative to cells harvested from the TMJ for TMJ tissue engineering. This finding may also apply to other fibrocartilages such as the intervertebral disc and knee meniscus in applications where a mature cartilage cell source is desired.

    To examine whether the maxillofacial skeletal morphology correlates with the condylar position and the anatomic characteristics of articular eminence using measurements of lateral cephalometric radiographs and individualized sagittal temporomandibular joint (TMJ) tomographs. I compared measurements of 202 TMJs of 101 orthodontic patients of Kangnung National University Dental Hospital. I used Pearson's correlation for comparison of the measuring values in lateral cephalometric radiographs and individualized sagittal TMJ tomographs. Large occlusal plane angle tendency showed decreased width of posterior eminence slope, decreased depth of articular fossa and decreased posterior slope angle of eminence. Large mandibular plane angle tendency showed decreased superior joint space, decreased superior joint space, decreased depth of articular fossa and decreased posterior slope angle of eminence. Large genial angle tendency showed decreased depth of articular fossa, decreased posterior slope angle of eminence and anterior position of comdylar head. Large anterior facial height and large posterior facial height tendency showed increased width of posterior position of condylar head. Maxillofacial skeletal morphology has correlation with the anatomic characteristics of TMJ. Individualized sagittal TMJ tomographs can provide useful information for anatomical analysis of TMJ.

    To determine the combined effect of oxygen level and glucose concentration on cell viability, ATP production, and matrix synthesis of temporomandibular joint (TMJ) disc cells. TMJ disc cells were isolated from pigs aged 6-8 months and cultured in a monolayer. Cell cultures were preconditioned for 48 h with 0, 1.5, 5, or 25 mM glucose DMEM under 1%, 5%, 10%, or 21% O2 level, respectively. The cell viability was measured using the WST-1 assay. ATP production was determined using the Luciferin-Luciferase assay. Collagen and proteoglycan synthesis were determined by measuring the incorporation of [2, 3-(3)H] proline and [(35)S] sulfate into the cells, respectively. TMJ disc cell viability significantly decreased (P oxygen levels significantly increased viability (P oxygen levels significantly reduced ATP production (P oxygen was significant in regards to cell viability (P oxygen are important, glucose is the limiting nutrient for TMJ disc cell survival. At low oxygen levels, the production of ATP, collagen, and proteoglycan are severely inhibited. These results suggest that steeper nutrient gradients may exist in the TMJ disc and it may be vulnerable to pathological events that impede nutrient supply.

    Sherman, Brian J.; McRae-Clark, Aimee L.

    2016-01-01

    Cannabis is the most commonly used illicit substance in the United States. Rates of cannabis use and cannabis use disorder have increased in the past decade, paralleling changes in the legal and political climate favoring legalization. Almost 20 million people aged 12 years or older report past-month cannabis use, and 8 million report daily or near-daily use. Concurrently, the perception that cannabis use poses a significant risk of negative consequences has decreased. Contrary to this perception, heavy cannabis use is associated with cognitive impairment, increased risk for psychotic disorders and other mental health problems, lower education attainment, and unemployment. Clinical trials of various treatments for cannabis use disorder have likewise increased, focusing primarily on psychotherapy treatments, specifically, motivational enhancement therapy, cognitive behavioral therapy, and contingency management. Their findings suggest that a combination of these three modalities produces the best abstinence outcomes, although abstinence rates remain modest and decline after treatment. More recently, pharmacotherapy trials have been conducted as adjunctive interventions to psychosocial treatment. N-acetylcysteine and gabapentin are two of the most promising medications, although no pharmacologic treatment has emerged as clearly efficacious. In this review, we provide a detailed summary of clinical trials that evaluated psychotherapy and pharmacotherapy for treating cannabis use disorder and discuss emerging areas of clinical research and cannabis-specific barriers to treatment.

    Preliminary findings suggest that Attention Deficit Hyperactivity Disorder (ADHD) may be associated with disordered eating behaviour, but whether there is sufficient evidence to suggest an association between ADHD and specific types of disordered eating behaviour is unclear. Furthermore, it is uncertain whether specific features associated with ADHD are differentially associated with disordered eating behaviour. A systematic review of seventy-five studies was conducted to evaluate the potential association between ADHD symptomatology and disordered eating behaviour and to provide an estimate of the strength of evidence for any association. Overall, a moderate strength of evidence exists for a positive association between ADHD and disordered eating and with specific types of disordered-eating behaviour, in particular, overeating behaviour. There is consistent evidence that impulsivity symptoms of ADHD are positively associated with overeating and bulimia nervosa and more limited evidence for an association between hyperactivity symptoms and restrictive eating in males but not females. Further research is required to assess the potential direction of the relationship between ADHD and disordered eating, the underlying mechanisms and the role of specific ADHD symptoms in the development and/or maintenance of disordered eating behaviour. We propose a framework that could be used to guide the design of future studies. Copyright © 2017 The Authors. Published by Elsevier Ltd.. All rights reserved.

    Based upon an analysis of 6 major historical technological advances over the last 150 years, a new syndrome, disruptive technology disorder (DTD), is introduced. DTD describes the human health ailments that accompany the implementation of disruptive technologies. Elevator sickness, railway spine, and bicycle face are representative examples. Though the underlying causative disruptive technologies may differ, many neurologic symptoms (headache, dizziness, weakness) are common to multiple DTDs. Born of technology-driven societal change, DTDs manifest as a complex interplay between biological and psychological symptoms. © 2017 American Academy of Neurology.

    2014-04-01

    Full Text Available Functional gastrointestinal disorders (FGIDs are a common problem in children. These disorders in children are classified into the following categories according to the ROME III classification: Functional Dyspepsia, Irritable bowel syndrome (IBS, Abdominal Migraines, Childhood Functional abdominal pain (FAP, Childhood functional abdominal pain syndrome and functional constipation. FGIDs are diagnosed based on history and normal physical examination provided that there is no evidence of underlying disease such as anatomical abnormalities, infectious, inflammatory and malignancies. This group of poorly defined diseases represent a huge treatment challenge to the specialist, because, until now there is no therapy that has been effective in improving the symptoms. FGIDs also cause deep family problems as the disease interrupts their routine and positive response to treatment is rarely seen. On the other hand there is no objective document of the disease neither endoscopic, radiologic nor pathologic. Therapeutic strategies of FGIDs are: education and parent's assurance, detection and modifying physical and psychological stress, dietary intervention, pharmacological treatment, psychotherapy and other complementary medical treatments. Some foods may trigger the illness such as coffee, fatty foods and spicy foods, therefore they should be avoided. Lactose-free diet cannot improve symptoms of FGIDs, except in children with lactose intolerance. The beneficial effect of fiber supplement in children with FGIDs remains unknown but it has been useful in adults with IBS. Probiotics have potential efficacy in treating IBS but the efficacy in children with FGIDs remains uncertain and needs to be further studied. In patients with severe symptoms, pharmacological agents can be effective. These drugs include Antacids, Prokinetics, Anticholinergic, Tricyclic antidepressants (TCAS and Serotonergic agents (Agonists and anti agonists. Psychotherapy in FAP and IBS is

  2. Temporomandibular disorders and tension-type headache.

    Science.gov (United States)

    Mongini, Franco

    2007-12-01

    Pathologies currently defined as temporomandibular disorders may be different in nature. Temporomandibular joint (TMJ) disorders and craniofacial and cervical myogenous pain (MP) are distinct pathologies but may be superimposed and share some etiologic factors. Tension-type headache (TTH) may often be associated with craniofacial and cervical pain, and the same pharmacologic and nonpharmacologic treatment may be efficacious for both. Psychiatric comorbidity (depression and/or anxiety disorder) is less frequent in sheer TMJ disorders, compared with MP and TTH. A screening for the presence of an underlying psychiatric disorder should be part of the clinical evaluation in patients suffering from headache and facial pain.

    The authors report their experience with temporomandibular joint (TMJ) traumas involving breakage of the roof of the glenoid cavity, an infrequent event that occurs in those cases in which, as a result of the condylar neck not fracturing, the traumatic energy is transmitted to the middle skull base. As the literature contains no valid series for establishing standardized protocols for the treatment of these fractures, we propose our own orthopedic-functional approach. The patient observed by us had suffered a cranio-facial trauma and presented the classical symptoms and signs of TMJ traumas and complete bilateral Bell paralysis. He was subjected to a CAT scan and then to 2-stage treatment consisting of functional rest with liquid diet followed by physiotherapy. An almost total recovery in TMJ function was observed after 1 month. At 1-year follow-up the facial paralysis had resolved completely. On the basis of our experience, breakages of the glenoid cavity can be compared, in terms of treatment procedure, to intracapsular fractures of the TMJ with surgery confined to cases of ankylosis sequelae. To avoid the onset of ankylosis careful control of clinical, functional and radiological follow-up is required.

    The temporomandibular joint (TMJ) functions as a load-bearing diarthrodial joint during mastication, and its continuous use and stress can lead to degeneration over age. Using senescence-accelerated (SAMP8) mice that develop early osteoarthritis-like changes in synovial joints at high frequency, we analyzed possible molecular mechanisms of TMJ degeneration and tested whether and how malocclusion may accelerate it. Condylar articular cartilage in young SAMP8 mice displayed early-onset osteoarthritic changes that included reductions in superficial/chondroprogenitor cell number, proteoglycan/collagen content, and Indian hedgehog (Ihh)-expressing chondrocytes. Following malocclusion induced by tooth milling, the SAMP8 condyles became morphologically defective, displayed even lower proteoglycan levels, and underwent abnormal chondrocyte maturation compared with malocclusion-treated condyles in wild-type mice. Malocclusion also induced faster progression of pathologic changes with increasing age in SAMP8 condyles as indicated by decreased PCNA-positive proliferating chondroprogenitors and increased TUNEL-positive apoptotic cells. These changes were accompanied by steeper reductions in Ihh signaling and by expression of matrix metalloproteinase 13 at the chondro-osseous junction in SAMP8 articular cartilage. In sum, we show for the first time that precocious TMJ degeneration in SAMP8 mice is accompanied by--and possibly attributable to--altered Ihh signaling and that occlusal dysfunction accelerates progression toward degenerative TMJ disease in this model.

    1991-01-01

    Double contrast arthrotomography combined with cinematography as a diagnostic instrument establishing functional and structural TMJ alterations is evaluated for its diagnostic value and reliability within the chain of diagnostic measures applied. In 131 patients double-contrast arthrotomography was followed by a comprehensive history of joint problems, and verification of the clinical findings as well as the arthrographic diagnosis and the post-arthrographic TMJ alterations. Our interest was focussed, among others, on the question whether arthrography alone would have any therapeutic effect or produce an alteration in TMJ function.

    2012-05-01

    Temporomandibular joint (TMJ) ankylosis is a devastating anatomico-pathological condition which severely affects the quality of human health. Over the last 70 years various treatments have been described to treat this distressing condition. But no single method has uniformly produced successful results. Although various surgical techniques have been improved periodically, the treatment results remain inefficient due to its recurrence as TMJ re-adhesion. Since recurrence remains as a problem in many cases, the TMJ ankylosis presents a major therapeutic challenge in head and neck surgery. The re-ankylosis is a unique phenomenon that so far has defied a full and logical explanation, based upon biological and mechanical factors that are linked together in a coherent fashion. Many factors have been implicated in the development of re-adhesion following TMJ surgery. But still the mechanism by which the TMJ re-adhesion develops is unclear. Hence, TMJ ankylosis demands an alternative effective treatment modality to prevent its recurrence as re-ankylosis. This paper postulates some critical biological factors responsible for re-ankylosis based on which a novel treatment modality is also proposed. Copyright © 2012 Elsevier Ltd. All rights reserved.

    2001-01-01

    To evaluate the osseous changes of TMJ in internal derangement and osteoarthritis patients using MRI. MR images of 111 TMJs in 64 patients were analyzed to evaluate the osseous changes. 111 TMJs were divided into 6 groups according to the radiologic Stages by Schellhas and Wilkes. On MR images, we evaluate the osseous changes of articular eminence and condylar head. The most frequent Stage in internal derangement of TMJ was Stage Ι. And 38 joints (25.2%) revealed osteoarthritis with internal derangement. When osseous change of articular eminence and condylar head occur, flattening was the most common osseous change. Sclerosis was observed in all Stages and osteophytosis of condylar head was observed in Stage ΙΙ (1.8%) and ΙΙΙ (0.9%). Out of 28 joints with osteoarthritis, 6 joints (21.4%) showed joint effusion. MR image revealed abnormal configuration of disk, but the detection of minimal osseous change was subtle

    Synovial chondromatosis is an uncommon disorder characterized by metaplastic formation of multiple cartilaginous and osteocartilaginous nodules within connective tissue of the synovial membrane of joints. Osteochondroma is a benign lesion of osseous and cartilagenous origin. It is frequently found in the general skeleton, but is rare in the mandibular condyle. We experienced 2 patients with abnormal appearance of temporomandibular joint. Histologic diagnoses were not obtained, because surgery was unwarranted in view of the lack of symptoms and the benign differential diagnosis. We describes 2 cases that show the characteristics of both disease simultaneously.

    This study aimed to estimate the absorbed dose in cone beam computed tomography (CBCT) exams according to different exposure parameters and size and position of the field of view (FOV). In addition was compared the absorbed dose of two smaller FOV scans with that of a larger FOV scan for evaluation of temporomandibular joint (TMJ), as it is a bilateral structure. CBCT scans were obtained on OP300 Maxio unit varying scanning mode (standard, high and endo) as well as size (5 x 5, 6 x 8 and 8 x 15 cm) and positioning of FOV. With a small FOV, different areas were scanned (maxilla or mandible, anterior or posterior and TMJ). Absorbed doses were determined using thermoluminescent dosimeters on the skin surface of sensitive organs of an anthropomorphic phantom. Endo mode showed the highest dose, followed by the high and standard modes in all FOV positions. With small FOV, doses were higher in the posterior region, especially in the mandible. Dose reduction occurred when small FOVs were used, but it was not proportional to FOV size reduction. For TMJ, the dose in a single acquisition with large FOV was greater than two acquisitions with small FOV, but lower than two acquisitions with medium FOV (6x8 cm). In conclusion, scanning mode, size and FOV position have great influence on the absorbed dose. Small FOV decreases the dose, but there is no linear relation between FOV size and dose. For bilateral exams of TMJ, double acquisition with small FOVs produces decrease in absorbed dose relative to a large FOV. (author)

    Aging is accompanied by a series of changes in mature tissues that influence their properties and functions. Collagen, as one of the main extracellular components of cartilage, becomes highly crosslinked during aging. In this study, the aim was to examine whether a correlation exists between collagen crosslinking induced by artificial aging and mechanical properties of the temporomandibular joint (TMJ) condyle. To evaluate this hypothesis, collagen crosslinks were induced using ribose incubation. Porcine TMJ condyles were incubated for 7 days with different concentrations of ribose. The compressive modulus and stiffness ratio (incubated versus control) was determined after loading. Glycosaminoglycan and collagen content, and the number of crosslinks were analyzed. Tissue structure was visualized by microscopy using different staining methods. Concomitant with an increasing concentration of ribose, an increase of collagen crosslinks was found. The number of crosslinks increased almost 50 fold after incubation with the highest concentration of ribose. Simultaneously, the stiffness ratio of the samples showed a significant increase after incubation with the ribose. Pearson correlation analyses showed a significant positive correlation between the overall stiffness ratio and the crosslink level; the higher the number of crosslinks the higher the stiffness. The present model, in which ribose was used to mimic certain aspects of age-related changes, can be employed as an in vitro model to study age-related mechanical changes in the TMJ condyle.

    2003-01-01

    To describe the MRI findings of the retrodiskal tissue in patients presenting with TMJ internal derangement and to correlate these findings with clinical and other MRI manifestations. One hundred eighteen joints of 63 patients with TMJ internal derangement were examined by MRI. T1-weighted sagittal MR images taken in both closed- and open-mouth were evaluated for the presence of demarcation between disk and retrodiskal tissue, the presence of low signal intensity, and the depiction of the temporal part of the posterior attachment. The results were correlated with the duration of TMJ internal derangement, the presence of pain, and other MRI findings, including the type of internal derangement, the extent of disk displacement, the degree of disc deformation, and the presence of osteoarthrosis. A significant relationship between the presence of low signal intensity in the retrodiskal tissue and other MRI findings was determined. Low signal intensity on the open-mouth view was observed more frequently in patients with disc displacement without reduction, severe disc displacement and deformation, and osteoarthrosis (p<0.05). The demarcation between disk and retrodiskal tissue, and the depiction of the temporal part of the posterior attachment (TPA) were correlated neither with clinical, nor with other MRI findings. This study suggests that low signal intensity in the retrodiskal tissue on open-mouth MR image can be indicative of advanced stages of disk displacement.

    To determine the relationship between clinical symptoms and magnetic resonance (MR) images in patients presenting with temporomandibular joint (TMJ) disorders. This study was based on 172 joints in 86 patients presenting with TMJ disorders. Joint pain and sound during jaw opening and closing movements were recorded, and the possible relationship between disc positions and bony changes of the condylar head and the articular fossa in MR images in the oblique sagittal planes were examined. Data were analyzed by Chi-square test. There was no statistically significant relationship between clinical symptoms and MR images in the patients with TMJ disorders. In the patient with TMJ disorders, joint pain and sound could not be specific clinical symptoms that are related with MR image findings, and asymptomatic joint did not necessarily imply that the joints are normal according to MR image findings.

    2011-01-01

    The objective of this study was to retrospectively analyze the incidence of the concurrent existence of temporomandibular disorders (TMD) and headaches. Forty patients (36 female, 4 male, mean age: 29.9±9.6 years) clinically diagnosed with TMD were screened. Patient records were analyzed regarding: range of mouth opening, temporomandibular joint (TMJ) noises, pain on palpation of the TMJ and masticatory muscles and neck and upper back muscles, and magnetic resonance imaging of the TMJ. According to patient records, a total of 40 (66.6%) patients were diagnosed with TMD among 60 patients with headache. Thirty-two (53%) patients had TMJ internal derangement (ID), 8 (13%) patients had only myofascial pain dysfunction (MPD) and 25 (41.6%) patients had concurrent TMJ ID/MPD. There were statistically significant relationships between the number of tender masseter muscles and MPD patients (p=0.04) and between the number of tender medial pterygoid muscles and patients with reducing disc displacement (RDD) (p=0.03). The TMJ and associated orofacial structures should be considered as possible triggering or perpetuating factors for headaches, especially tension-type. There might be a significant connection between TMD and headache. However, most medical and dental practitioners are unaware of this relationship. Therefore, a careful evaluation of the TMJ and associated orofacial structures is required for a correct interpretation of the craniofacial pain in headache patients, and these patients should be managed with a multidisciplinary approach.

    This study determined whether there is an increased risk of tinnitus in patients with temporomandibular joint (TMJ). We used information from health insurance claims obtained from Taiwan National Health Insurance (TNHI). Patients aged 20 years and older who were newly diagnosed with TMJ disorder served as the study cohort. The demographic factors and comorbidities that may be associated with tinnitus were also identified, including age, sex, and comorbidities of hearing loss, noise effects on the inner ear, and degenerative and vascular ear disorders. A higher proportion of TMJ disorder patients suffered from hearing loss (5.30 vs. 2.11 %), and degenerative and vascular ear disorders (0.20 vs. 0.08 %) compared with the control patients. The crude hazard ratio (HR) of tinnitus in the TMJ disorder cohort was 2.73-fold higher than that in the control patients, with an adjusted HR of 2.62 (95 % CI = 2.29-3.00). The comorbidity-specific TMJ disorder cohort to the control patients' adjusted HR of tinnitus was higher for patients without comorbidity (adjusted HR = 2.75, 95 % CI = 2.39-3.17). We also observed a 3.22-fold significantly higher relative risk of developing tinnitus within the 3-year follow-up period (95 % CI = 2.67-3.89). Patients with TMJ disorder might be at increased risk of tinnitus.

    Monoclonal-antibody has been used for patients with autoimmune disorders for several years, and efficacy and safety were appreciated for these patients. Neuromyelitis optica specturm disorder (NMOSD) has been defined as an autoimmune demyelination disorder of the central nervous system (CNS) with a course of relapse-remission. Treatment of prevention is important for patients with NMOSD because of the increased disability after several attacks. Multiple factors were involved in the pathogenesis of NMOSD. Currently, targeting specific factor was favored in the research into the treatment for NMOSD. Previous studies reported the efficacy and tolerance in NMOSD for drugs such as rituximab, tocilizumab, and eculizumab. The aim of this article is to review the current monoclonal therapies for NMOSD patients, and also future alternative options.

    1983-07-01

    An earlier study of 50 patients with occlusions restored by fixed partial dentures indicated a high percent (68%) of TMJ dysfunction. Occlusal interferences can play a significant role in causing TMJ dysfunction. To determine the significance of occlusal interferences, occlusal splints were placed in 10 of these restored patients who had moderate to severe dysfunction. The PRI was used to detect the presence or absence of TMJ dysfunction. The PRI TMJ dysfunction scores were reduced in all 10 patients after use of the occlusal splint. Five of the patients achieved reproducible tracings (no TMJ dysfunction) during the experiment time of 7 months. The occlusion of two patients was adjusted to eliminate the need for the occlusal splint. Patients who wore the splint 24 hours a day showed a significant (0.0004 level) reduction in TMJ dysfunction. Those patients who did not wear the splint regularly or had high levels of stress had PRI scores that varied. This finding indicates that the occlusal splint is not a treatment, as its removal permits reactivation of the occlusal interference. Resolution of dysfunction did not occur until occlusal interferences were removed. The changes in PRI scores to different dysfunction categories (none, slight, moderate, and severe) for the experimental group were significant at the 0.01 level. A control group of five patients had similar pantographic tracings but no other treatment. Their PRI scores varied, but there was no significant change in PRI scores or dysfunction categories. It was concluded that occlusal interferences were active causes of TMJ dysfunction in 10 of 36 patients in a population with restored occlusions.

Clinicians may also question service users' ability to make considered decisions about their treatment when in crisis. Therefore, this qualitative study aimed to investigate crisis treatment preferences of a sample of community-dwelling adults with borderline personality disorder. Participants were 41 adults with borderline personality disorder who had created joint crisis plans during a randomized controlled trial. Data from all 41 joint crisis plans were analyzed iteratively via a thematic analysis framework. Participants gave clear statements in their crisis plans relating to the desire to recover from the crisis and to improve their social functioning. Key themes included the desire to be treated with dignity and respect and to receive emotional and practical support from clinicians. Many participants spoke of the importance of connecting with others during periods of crisis, but several reported a clear desire to be left alone during a future crisis. Other themes concerned preferences for specific treatment refusals during crises, including particular types of psychotropic medication and involuntary treatment. The variation of participants' preferences underscores the importance of developing individually tailored crisis plans for people with borderline personality disorder. The need to be treated with dignity and respect and to be given autonomy in decision making--also identified in global surveys of people with severe mental illness--is important to people with borderline personality disorder. Key messages for clinicians, service users, and policy makers, in addition to staff training issues, are discussed.

    The objective of this study is to evaluate a woman's risk perception for future cardiovascular disease (CVD) after being diagnosed with a hypertensive disorder of pregnancy. A prospective cohort of women diagnosed with a hypertensive disorder of pregnancy (HDP) was studied. Each woman completed two surveys, one prior to hospital discharge and one 2 weeks later, designed to assess knowledge of and risk perception for future CVD based on their recent diagnosis of a HDP. Rates of postpartum depression were also assessed. Of the 146 subjects included, 28% were diagnosed with preeclampsia with severe features, 52.1% with preeclampsia with mild features, and 19.9% had chronic hypertension. Women with severe features and those delivering preterm were more likely to report a perception of increased risk of both recurrent HDP in a future pregnancy (p = 0.004 and 0.005, respectively) and hypertension later in life (p = 0.01 and 0.03, respectively). Women delivering preterm were more likely to report an accurate perception of increased risk of myocardial infarction and stroke compared to those delivering at term (p = 0.006 and 0.002, respectively). Disease severity and preterm delivery were associated with a higher likelihood of the perception of an increased risk for both recurrent HDP and hypertension in the future. Only preterm delivery was associated with a higher risk perception for stroke and myocardial infarction. Interventions targeted at improved health awareness in women diagnosed with HDP are warranted.

    Purpose: We aimed to assess the contrast enhancement patterns of the retrodiscal tissue with dynamic contrast-enhanced MR imaging (DCE-MRI) with respect to different temporomandibular joint disc pathologies. Additionally, we questioned the relationship between the temporomandibular joint (TMJ) pain and the contrast enhancement pattern of the retrodiscal tissue regardless of the TMJ disc position. Materials and methods: 52 joints of 26 patients (4 males and 22 females) who have pain in at least at one of their TMJ were included in this study. For the qualitative analysis, the joints were divided into four groups in terms of their disc positions: normal (1), partially displaced with or without reduction (2), totally dislocated with reduction (3) and totally dislocated without reduction (4). Besides, two different joint groups were constituted, namely the painful group and painless group according to the clinical findings without taking the TMJ disc positions into account. Quantitative analyses were made by means of measuring signal intensity ratios (SI) ratio at the retrodiscal tissue (from internal side and external side of the each joint) using DCE-MRI and these measurements were analyzed with paired samples t test to define the difference between the measurements. At the second stage, the time-dependent arithmetical mean values of the SI ratios were calculated for each joint group and significant differences between the groups were questioned using analysis of variance (ANOVA) test. Besides, painful and painless groups which were classified on the basis of the clinical data were compared according to the mean SI ratios found for each joint and the significant differences between these two groups were assessed by means of Student's T test. The results were assessed in 95% confidence interval where the significance level was p < 0.05. Results: A significant difference was observed between the internal and external contrast enhancement of the joints with partial

    Juvenile idiopathic arthritis is the most common chronic rheumatic condition during childhood. Temporomandibular joint arthritis is frequently asymptomatic. When it takes place during childhood, it may affect condylar growth; therefore, these children are at risk of unfavorable long-term outcomes from the associated joint damage. The etiology is not completely understood, but it is considered as multifactorial with both genetic and environmental factors involved. The standardized examination and imaging protocols serve important purpose to diagnose temporomandibular joint (TMJ) arthritis not only to establish an early interventional strategy but also to assess craniofacial growth and the progression of signs and symptoms in those patients. Although the treatment of juvenile idiopathic arthritis (JIA) has changed dramatically over the last decades due to new therapeutic options, TMJ arthritis still can develop during the course of the disease. In clinical experience, TMJs appear to respond less well to the standard of care used to treat other joints. More individualized approach to the patient's treatment serves as the main goal of personalized medicine. It could be achieved by adopting new methods of medical imaging such as conebeam computer tomography as well as developing reliable biomarkers which may assist with predicting disease type, course, or severity and predicting response to medication. This article provides an overview of current information on orofacial complications in JIA and its management. Based on information provided in this review, more precise diagnosis, proper tools for recognizing people at risk, and more efficient treatment approaches could be implemented. This may lead to more personalized treatment management strategies of TMJ complications of JIA patients.

    Full Text Available Current notions of “hearing impairment,” as reflected in clinical audiological practice, do not acknowledge the needs of individuals who have normal hearing pure tone sensitivity but who experience auditory processing difficulties in everyday life that are indexed by reduced performance in other more sophisticated audiometric tests such as speech audiometry in noise or complex non-speech sound perception. This disorder, defined as “Auditory Processing Disorder” (APD or “Central Auditory Processing Disorder” is classified in the current tenth version of the International Classification of diseases as H93.25 and in the forthcoming beta eleventh version. APDs may have detrimental effects on the affected individual, with low esteem, anxiety, and depression, and symptoms may remain into adulthood. These disorders may interfere with learning per se and with communication, social, emotional, and academic-work aspects of life. The objective of the present paper is to define a baseline European APD consensus formulated by experienced clinicians and researchers in this specific field of human auditory science. A secondary aim is to identify issues that future research needs to address in order to further clarify the nature of APD and thus assist in optimum diagnosis and evidence-based management. This European consensus presents the main symptoms, conditions, and specific medical history elements that should lead to auditory processing evaluation. Consensus on definition of the disorder, optimum diagnostic pathway, and appropriate management are highlighted alongside a perspective on future research focus.

    The purpose of study was to evaluate the influence of a head and neck radiologist after MRI examinations of the temporomandibular joint on the therapeutic strategy in patients with temporomandibular disorders and, furthermore, to analyze interobserver agreement for defined MRI criteria. Eighteen patients including 36 TMJ (10 males and 8 females; age 15-53 years) were enrolled. All were clinically evaluated, diagnosed ''TMD'' and MRI examinations were performed. The medical and MRI records of 18 patients were retrospectively reviewed. Four MR images (proton density, T1, T2-weighted and Gd-DTPA enhanced sagittal images at the open and closed mouth) were obtained. Therapeutic strategies before and after performance of the MRI were compared. One radiologist and main dentist independently analyzed the sagittal MR images for position of the disk, position of the condyle, signal intensity of the disk and bilaminar zone, bone changes and several additional findings. Additionally, the agreement between one radiologist and main dentist with respect to the diagnoses was evaluated. There were 13 cases that the modification of diagnosis was needed after MRI examinations. In 10 of the 18 subjective symptom-free subjects, there were abnormal signs anatomically. Also in 1 subjective and objective symptom-free subjects, abnormal signs were seen on MRI. In 1 individual, MRI revealed larger abnormal signs in clinically asymptomatic TMJ as compared with symptomatic TMJ. Whereas as for 1 symptomatic subject, Abnormal signs could not be identified in any of the TMJs. There were no cases that the change of treatment methods was needed after MRI examinations, but as for 13 cases, the correction of treatment contents was needed, such as the changes of the therapeutic regimen and the form of the sprint were registered after MRI. The disagreement between one radiologist and main dentist was seen in: the bone change of condyle; 30 TMJs, the change of temporal bone ;6 TMJs, the relationship

    Borderline personality disorder (BPD) is a common mental disorder characterized by a pervasive pattern of emotional Borderline personality disorder (BPD) is a common mental disorder characterized by a pervasive pattern of emotional lability, impulsivity, interpersonal difficulties, identity disturbances, and disturbed cognition. Traditional pharmacotherapies are effective in treating some of these core symptoms but have only modest effects on the domain of interpersonal dysfunction of BPD. Thus there is a need to develop new, neurobiologically informed pharmacological treatments for BPD. This review focuses on the potential use of intranasal oxytocin (OXT), which has key roles in the regulation of complex social cognition and behaviors, to target symptoms of interpersonal dysfunction in BPD. Surprisingly, despite promising data on the prosocial effects of OXT, only 5 trials in BPD have been published to date. These trials show mixed results with on one hand, a decrease of emotional responses to stress and on the other hand, some "paradoxical" reactions with worsened interpersonal anxiety and decreased cooperative behavior. These mixed results are interpreted according to different theoretical models and also in light of some methodological limitations. Further studies are needed to understand the effect of OXT in patients with BPD and ongoing clinical trials will provide some answers to remaining questions on the use of OXT in BPD. Recommendations for future studies are also proposed in this review.

    The use of computers, especially for virtual reality (VR), to understand, assess, and treat various mental health problems has been developed for the last decade, including application for phobia, post-traumatic stress disorder, attention deficits, and schizophrenia. However, the number of VR tools addressing obsessive-compulsive disorder (OCD) is still lacking due to the heterogeneous symptoms of OCD and poor understanding of the relationship between VR and OCD. This article reviews the empirical literatures for VR tools in the future, which involve applications for both clinical work and experimental research in this area, including examining symptoms using VR according to OCD patients' individual symptoms, extending OCD research in the VR setting to also study behavioral and physiological correlations of the symptoms, and expanding the use of VR for OCD to cognitive-behavioral intervention.

    There is an urgent need for new and advanced approaches to modeling the pathological mechanisms of complex human neurological disorders. This is underscored by the decline in pharmaceutical research and development efficiency resulting in a relative decrease in new drug launches in the last several decades. Induced pluripotent stem cells represent a new tool to overcome many of the shortcomings of conventional methods, enabling live human neural cell modeling of complex conditions relating to aberrant neurodevelopment, such as schizophrenia, epilepsy and autism as well as age-associated neurodegeneration. This review considers the current status of induced pluripotent stem cell-based modeling of neurological disorders, canvassing proven and putative advantages, current constraints, and future prospects of next-generation culture systems for biomedical research and translation.

    It might seem difficult to describe the outcome of the proposals by the American Psychiatric Association's (APA) Personality and Personality Disorders Work Group (PPDWG) to be a success, given that all of the proposals were ultimately rejected. Nevertheless, one can interpret the result as a step forward, because the final outcome might not have been much different if a more conservative approach was adopted at the outset. The PPDWG did provide a significant contribution to the field through the provision of proposals that will likely generate a considerable body of informative research. The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) effort and suggestions for the future are discussed with respect to magnitude of change, documentation of empirical support, and addressing opposition.

    Full Text Available Autism and autism spectrum disorders (ASDs are heterogeneous neurodevelopmental disorders. They are enigmatic conditions that have their origins in the interaction of genes and environmental factors. ASDs are characterized by dysfunctions in social interaction and communication skills, in addition to repetitive and stereotypic verbal and nonverbal behaviours. Immune dysfunction has been confirmed with autistic children. There are no defined mechanisms of pathogenesis or curative therapy presently available. Indeed, ASDs are still untreatable. Available treatments for autism can be divided into behavioural, nutritional, and medical approaches, although no defined standard approach exists. Nowadays, stem cell therapy represents the great promise for the future of molecular medicine. Among the stem cell population, mesenchymal stem cells (MSCs show probably best potential good results in medical research. Due to the particular immune and neural dysregulation observed in ASDs, mesenchymal stem cell transplantation could offer a unique tool to provide better resolution for this disease.

    Full Text Available Temporomandibular joint (TMJ forms an integral functional part of stomatognathic system. Position, shape, structure and function of teeth have an influence on the proper functioning and health of TMJ. But a problem associated with TMJ is often neglected, and treatment for it is mostly restricted to palliative therapy. A proper understanding of the underlying cause of temporomandibular joint disorder (TMD is necessary to device a proper treatment plan. Etiology of TMDs varies from idiopathic reasons to systemic disorders. The option of Gnathological splint is a conservative, safe and an effective mode of therapy for TMDs caused by occlusal discrepancies (fulcrum/interferences. This article presents a case report of a patient with TMD caused by occlusal discrepancy

    To review the scientific literature examining gambling behavior in military veterans in order to summarize factors associated with gambling behavior in this population. Database searches were employed to identify articles specifically examining gambling behavior in military veterans. Cumulative search results identified 52 articles (1983-2017) examining gambling behavior in veteran populations. Articles generally fell into one or more of the following categories: prevalence, psychological profiles and psychiatric comorbidities, treatment evaluations, measurement, and genetic contributions to gambling disorder. Results from reviewed articles are presented and implications for future research discussed. Research to date has provided an excellent foundation to inform potential screening, intervention and research activities going forward. The authors suggest that a public health approach to future research endeavors would strengthen the evidence base regarding gambling in veteran populations and better inform strategies for screening, prevention and treatment.

    Because the concept of whiplash as a causative factor for temporomandibular disorders (TMD) is highly controversial, we decided to do a retrospective analysis of patients treated in our office who had sustained whiplash injuries and were treated for cervical and temporomandibular disorders. The records of 300 patients with TMD preceded by a motor vehicle accident were examined retrospectively. The most common presenting symptoms, in order, were: jaw pain, neck pain, post-traumatic headache, jaw fatigue, and severe temporomandibular joint (TMJ) clicking. The most common TMD diagnoses were: masseter trigger points, closing jaw muscle hyperactivity, TMJ synovitis, opening jaw muscle hyperactivity, and advanced TMJ disk derangement. Based primarily on the physical examination, we concluded that the TMJ and surrounding musculature should be examined similarly to other joints, with no preconceived notion that TMD pathology after whiplash is unlikely.

    Binge eating disorder (BED) is characterized by recurrent binge eating and marked distress about binge eating without the extreme compensatory behaviors for weight control that characterize other eating disorders. BED is prevalent, associated strongly with obesity, and is associated with heightened levels of psychological, psychiatric, and medical concerns. This article provides an overview of randomized controlled treatments for combined psychological and pharmacological treatment of BED to inform current clinical practice and future treatment research. In contrast to the prevalence and significance of BED, to date, limited research has been performed on combining psychological and pharmacological treatments for BED to enhance outcomes. Our review here found that combining certain medications with cognitive behavioral therapy (CBT) or behavioral weight loss (BWL) interventions produces superior outcomes to pharmacotherapy only but does not substantially improve outcomes achieved with CBT/BWL only. One medication (orlistat) has improved weight losses with CBT/BWL albeit minimally, and only one medication (topiramate) has enhanced reductions achieved with CBT in both binge eating and weight. Implications for future research are discussed.

    2015-01-01

    The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, formally recognizes a dissociative subtype of posttraumatic stress disorder (PTSD; PTSD with dissociative symptoms). This nomenclative move will boost empirical and theoretical efforts to further understand the links between dissociation, trauma, and PTSD. This article examines the empirical literature showing that patients with PTSD can be divided into 2 different groups based on their neurobiology, psychological symptom profile, history of exposure to early relational trauma, and depersonalization/derealization symptoms. It then explores the conceptual and empirical challenges of conceiving 1 of these types as reflecting a "dissociative" type of PTSD. First, this classification is based on the presence of a limited subset of dissociative symptoms (i.e., depersonalization, derealization). This sets aside an array of positive and negative psychoform and somatoform dissociative symptoms that may be related to PTSD. Second, empirical evidence suggests heightened dissociation in PTSD compared to many other disorders, indicating that dissociation is relevant to PTSD more broadly rather than simply to the so-called dissociative subtype. This article sets out important issues to be examined in the future study of dissociation in PTSD, which needs to be informed by solid conceptual understandings of dissociation.

    Bruxism, as an etiological factor for the development of TMD, includes different disorders of the TMJ and the masticatory muscles, exhibiting pain and disruption of the stomatognathic functions. Our goal was to study patients with bruxism and TMD from everyday dental clinical practice, in terms of diagnosis, identification of etiological factors, classification and treatment of these disorders. We treated 120 patients, divided into 2 groups of 60 patients. The first group had disorders of the TMJ, and the second of the masticatory muscles. The groups were divided into subgroups of 20 patients with dislocation of the articular disk with or without reduction and inflammation of TMJ. The second group was organized from patients with myofascial pain, myositis and muscular trismus. Our conservative treatment consisted of patient education, NSAID, myorelaxants, fabrication of prosthetics, repositioning and stabilization splints. The progress of the patients was followed immediately after the delivery of the prosthetics and the splint, after 1, 6 and 12 months. The results showed that in patients with disorders of the TMJ there were visible signs of recovery after 6 months in 68.3% patients, and in 85% after 12 months. In the second group we achieved faster results with the elimination of symptoms. Patients with afflictions of the muscles in 88.3% of cases noticed relief of symptoms even after 6 months and in 98.3% after 12 months. As therapists we concluded that timely treated complications of bruxism and TMD prevent the destruction of the TMJ, masticatory muscles and the entire stomatognatic system.

    ABSTRACT Objective: To assess the distribution of stress produced on TMJ disc by chincup therapy, by means of the finite element method. Methods: a simplified three-dimensional TMJ disc model was developed by using Rhinoceros 3D software, and exported to ANSYS software. A 4.9N load was applied on the inferior surface of the model at inclinations of 30, 40, and 50 degrees to the mandibular plane (GoMe). ANSYS was used to analyze stress distribution on the TMJ disc for the different angulations, by means of finite element method. Results: The results showed that the tensile and compressive stresses concentrations were higher on the inferior surface of the model. More presence of tensile stress was found in the middle-anterior region of the model and its location was not altered in the three directions of load application. There was more presence of compressive stress in the middle and mid-posterior regions, but when a 50o inclined load was applied, concentration in the middle region was prevalent. Tensile and compressive stresses intensities progressively diminished as the load was more vertically applied. Conclusions: stress induced by the chincup therapy is mainly located on the inferior surface of the model. Loads at greater angles to the mandibular plane produced distribution of stresses with lower intensity and a concentration of compressive stresses in the middle region. The simplified three-dimensional model proved useful for assessing the distribution of stresses on the TMJ disc induced by the chincup therapy. PMID:29160348

Assessment of location of mandibular joint heads and determination of its spatial position in patients with TMJ MJD before treatment and after it using CT.Materials and methods. 50 patients 28-62 years old, 37 women and 13 men who underwent computed tomography (CT of TMJ were under observation.The results of observation were analyzed in details.The studies were carried out using cone-radial computed tomographic scanner «Vatech Pax uni 3d». CT of TMJ was carried out in habitual occlusion before the start of treatment and after removal of TMJ MJD symptoms and complaints. At the study there were measured the width of joint fissure in front, upper and back segments according to N.A. Rabuhina methodology in N.E. Androsova and so-authors modification. Statistical analysis of the data received was carried out using «Statistics» (Statsoft, Inc program.Results. The results of TMJ CT in patients before the start of treatment demonstrated that the sizes of TMJ joint fissure were different. The width of the upper segment of TMJ joint fissure in patients before the start of treatment was reliably less (≤0,001 comparing with an analogous parameter in the group of patients after treatment that indicates the upper location of mandibular head in TMJ with reducing the height of the lower segment of face.So the data of study of the joint fissure width received using TMJ CT demonstrate formation of specific outlines of joint fissure at displacement of mandible and consequently joint head. Information about the joint fissure parameters allows rationally plan and realize orthopedic treatment and the necessary rehabilitation measures in patients with TMJ MJD.Conclusions.

    The purpose of this study was to develop a system for the measurement and simulation of the TMJ movement and to analyze the mandibular movement quantitatively. We devised patient-specific splints and a registration body for the TMJ movement tracking. The mandibular movements of the 12 subjects with facial deformity and 3 controls were obtained by using an optical tracking system and the patient-specific splints. The mandibular part was manually segmented from the CT volume data of a patient. Three-dimensional surface models of the maxilla and the mandible were constructed using the segmented data. The continuous movement of the mandible with respect to the maxilla could be simulated by applying the recorded positions sequentially. Trajectories of the selected reference points were calculated during simulation and analyzed. The selected points were the most superior point of bilateral condyle, lower incisor point, and pogonion. There were significant differences (P<0.05) between control group and pre-surgical group in the maximum displacement of left superior condyle, lower incisor, and pogonion in vertical direction. Differences in the maximum lengths of the right and the left condyle were 0.59 ± 0.30 mm in pre-surgical group and 2.69 ± 2.63 mm in control group, which showed a significant difference (P<0.005). The maximum of differences between lengths of the right and the left calculated during one cycle also showed a significant difference between two groups (P<0.05). Significant differences in mandibular movements between the groups implies that facial deformity have an effect on the movement asymmetry of the mandible.

    The establishment of robust and replicable behavioural testing paradigms with translational value for psychiatric diseases is a major step forward in developing and testing etiology-directed treatment for these complex disorders. Based on the existing literature, we have generated an inventory of applied rodent behavioural testing paradigms relevant to autism spectrum disorders (ASD). This inventory focused on previously used paradigms that assess behavioural domains that are affected in ASD, such as social interaction, social communication, repetitive behaviours and behavioural inflexibility, cognition as well as anxiety behaviour. A wide range of behavioural testing paradigms for rodents were identified. However, the level of face and construct validity is highly variable. The predictive validity of these paradigms is unknown, as etiology-directed treatments for ASD are currently not on the market. To optimise these studies, future efforts should address aspects of reproducibility and take into account data about the neurodevelopmental underpinnings and trajectory of ASD. In addition, with the increasing knowledge of processes underlying ASD, such as sensory information processes and synaptic plasticity, phenotyping efforts should include multi-level automated analysis of, for example, representative task-related behavioural and electrophysiological read-outs.

    Recent neuroscientific research demonstrates that the human brain is becoming altered by technological devices. Improvements in biotechnologies and computer based technologies are now increasing the likelihood for the development of brain augmentation devices in the next 20 years. We have developed the idea of an "Endomyccorhizae like interface" (ELI) nanocognitive device as a new kind of future neuroprosthetic which aims to facilitate neuronal network properties in individuals with neurodegenerative disorders. The design of our ELI may overcome the problems of invasive neuroprosthetics, post-operative inflammation, and infection and neuroprosthetic degradation. The method in which our ELI is connected and integrated to neuronal networks is based on a mechanism similar to endomyccorhizae which is the oldest and most widespread form of plant symbiosis. We propose that the principle of Endomyccorhizae could be relevant for developing a crossing point between the ELI and neuronal networks. Similar to endomyccorhizae the ELI will be designed to form webs, each of which connects multiple neurons together. The ELI will function to sense action potentials and deliver it to the neurons it connects to. This is expected to compensate for neuronal loss in some neurodegenerative disorders, such as Alzheimer's disease and Parkinson's disease.

    It is a difficult undertaking to design a classification system for any disease entity, let alone for oro-facial pain (OFP) and more specifically for temporomandibular disorders (TMD). A further complication of this task is that both physical and psychosocial variables must be included. To augment this process, a two-step systematic review, adhering to PRISMA guidelines, of the classification systems published during the last 20 years for OFP and TMD was performed. The first search step identified 190 potential citations which ultimately resulted in only 17 articles being included for in-depth analysis and review. The second step resulted in only 5 articles being selected for inclusion in this review. Five additional articles and four classification guidelines/criteria were also included due to expansion of the search criteria. Thus, in total, 14 documents comprising articles and guidelines/criteria (8 proposals of classification systems for OFP; 6 for TMD) were selected for inclusion in the systematic review. For each, a discussion as to their advantages, strengths and limitations was provided. Suggestions regarding the future direction for improving the classification process with the use of ontological principles rather than taxonomy are discussed. Furthermore, the potential for expanding the scope of axes included in existing classification systems, to include genetic, epigenetic and neurobiological variables, is explored. It is therefore recommended that future classification system proposals be based on combined approaches aiming to provide archetypal treatment-oriented classifications. © 2017 John Wiley & Sons Ltd.

    The present study was conducted to investigate the relationship between magnetic resonance imaging (MRI) of the temporomandibular joint (TMJ) and clinical findings of patients having symptoms of temporomandibular disorders, and to consider the possibility to grasp the internal derangement of the TMJ from clinical findings. Subjects were 80 patients who visited to ask orthodontic treatment 16 males and 64 females. The average age was 22 years and 4 months. We performed a investigation of both their previous and present illness. In addition, to decide the correct condition concerning the internal derangement of the TMJ, patients were given MRI examinations (G. E. medical system Signa 1.5 Tesla) before orthodontic treatment. Results were as follows: The three symptoms of temporomandibular disorders-noise, pain, and abnormal mandibular movement, were not related to constant disk displacement. It seemed difficult to infer and obtain the diagnosis of the condition of internal derangement of the TMJ only from clinical findings. In a dental clinics having no medical imaging instrument such as MRI, it was, however, considered that the following items will make it possible to define the condition of internal derangements of the TMJ from clinical findings. As to respects concerning clinical findings, it is necessary to consider the previous illness as well as present illness. TMJ noise indicates a higher relationship to the disk displacement in MRI findings. The temporomandibular joint with plural symptoms indicated a higher incidence of disk displacement examined by MR Imaging than that with a single symptom. (author)

    Pathologic gambling disorder and problem gambling are becoming increasingly common in the United States as more states legalize gambling. Although gambling-related disorders can cause devastating consequences, well-studied treatments are few. Fortunately, clinical experience suggests that pathologic gambling disorder is highly treatable. In this article, Drs Sumitra and Miller briefly summarize gambling-related disorders and discuss available, effective treatments.

It has variously been hypothesized that APD is predicted by childhood conduct disorder (CD), attention-deficit/hyperactivity disorder (ADHD), or both disorders. To test these competing hypotheses, the authors used data from a…

  20. Visual processing in anorexia nervosa and body dysmorphic disorder: similarities, differences, and future research directions

    Science.gov (United States)

    Madsen, Sarah K.; Bohon, Cara; Feusner, Jamie D.

    2013-01-01

    Anorexia nervosa (AN) and body dysmorphic disorder (BDD) are psychiatric disorders that involve distortion of the experience of one’s physical appearance. In AN, individuals believe that they are overweight, perceive their body as “fat,” and are preoccupied with maintaining a low body weight. In BDD, individuals are preoccupied with misperceived defects in physical appearance, most often of the face. Distorted visual perception may contribute to these cardinal symptoms, and may be a common underlying phenotype. This review surveys the current literature on visual processing in AN and BDD, addressing lower- to higher-order stages of visual information processing and perception. We focus on peer-reviewed studies of AN and BDD that address ophthalmologic abnormalities, basic neural processing of visual input, integration of visual input with other systems, neuropsychological tests of visual processing, and representations of whole percepts (such as images of faces, bodies, and other objects). The literature suggests a pattern in both groups of over-attention to detail, reduced processing of global features, and a tendency to focus on symptom-specific details in their own images (body parts in AN, facial features in BDD), with cognitive strategy at least partially mediating the abnormalities. Visuospatial abnormalities were also evident when viewing images of others and for non-appearance related stimuli. Unfortunately no study has directly compared AN and BDD, and most studies were not designed to disentangle disease-related emotional responses from lower-order visual processing. We make recommendations for future studies to improve the understanding of visual processing abnormalities in AN and BDD. PMID:23810196

    To evaluate the effect of prenatal acetaminophen exposure on the future development of attention deficit/hyperactivity disorder (ADHD) in children. Literature searches of MEDLINE (1975 to June 2015), International Pharmaceutical Abstracts (1975 to June 2015), and Cochrane Database (publications through June 2015) for prospective clinical trials assessing the relationship of prenatal acetaminophen exposure and the development of attention deficit disorders or hyperactivity. Studies comparing self-reported maternal acetaminophen use during pregnancy to development of ADHD or ADHD-like behaviors in offspring between the ages of 3 and 12 years. Four studies examining the effects of prenatal acetaminophen exposure on subsequent ADHD behaviors were identified. Of these, one early study found no link to ADHD behaviors while the other studies found statistically significant correlations with the most prominent being a study finding a higher risk for using ADHD medications (hazard ratio = 1.29; 95% CI, 1.15-1.44) or having ADHD-like behaviors at age 7 years as determined by the Strengths and Difficulties Questionnaire (risk ratio = 1.13; 95% CI, 1.01-1.27) in children whose mothers used acetaminophen during pregnancy. While there does appear to be a mild correlation between prenatal acetaminophen use and the development of ADHD symptoms in children, current data do not provide sufficient evidence that prenatal acetaminophen exposure leads to development of ADHD symptoms late in life. Acetaminophen is a preferred option for pain management during pregnancy when compared with other medications such as nonsteroidal anti-inflammatory drugs or opioids for pyretic or pain relief. © The Author(s) 2015.

    Conclusions: The findings of this unique historical-prospective qualitative analysis of interviews performed before the onset of psychosis, confirmed previous findings of premorbid abnormality of future non-affective psychosis patients. Using qualitative analysis enabled obtaining a more in-depth understanding of the real-life experience of the premorbid period among patients with non-affective psychotic disorders.

  3. A clinical and radiological study on the internal derangement of TMJ

    Internal derangement of the temporomandibular joint can be defined an abnormal relationships of the meniscus relative to the mandibular condyle, articular fossa and dminence. This may cause variable mandibular dysfunctions and pain. For diagnosis, arthrography, computed tomography and amgnetic resonance imaging are used. In this study, the author reviewed 98 TMJs of 88 patients who were diagnosed as internal derangement through inferior joint space arthrography at the department of Oral and Maxillofacial Radiology, Dental Hospital, Dankook university through 1986 to 1992. 98 TMJs consisting of 30 disc displacement with reduction, 48 disc displacement without reduction and 20 perforation were studied about clinical and radiological findings. The results were as follows: 1. Internal derangement was found most frequently in the 2nd, 3rd decades and the average age of perforation was higher than that of disc displacement with higher than that of disc displacement with reduction. The sexual predilection was 2 times higher in females. 2. The most frequent chief complaints were TMJ sound in disc displacement with reduction, pain and limitation of mouth opening in disc displacement without reduction and pain in perforation. The duration of the chief complaints was longer in disc displacement with reduction with than in perforation and disc displacement without reduction. 3. Reciprocal click was the most frequently TMJ sound in disc displacement with reduction. History of joint sound in disc displacement without reduction an crepitus in perforation was the most frequent one. 4. The average maximum opening was 45.4 mm in disc displacement with reduction, 31.4 mm in disc displacement without reduction and 33.8 mm in perforation. 5. In the centric occlusion, posterior condylar position was the most frequent in disc displacement with reduction. Posterior and concentric condylar position was frequent in disc displacement without reduction, concentric and anterior condylar

    Cognitive Behavioural Therapy (CBT) is a form of evidence-based talking therapy that emphasises the importance of behaviour and conscious thoughts in shaping our emotional experiences. As pain becomes increasingly accepted as not only a sensory but also an emotional experience, success in using CBT to treat emotional disorders has resulted in the incorporation of cognitive-behavioural principles into the management of chronic pain. Outcomes of CBT-informed interdisciplinary pain management programmes are modest at best, despite rapid methodological improvements in trial design and implementation. Whilst the field searches for new treatment directions, a hybrid CBT approach that seeks to simultaneously tackle pain and its comorbidities shows promise in optimising treatment effectiveness and flexibility. This article provides a brief description of the core characteristics of CBT and the transformation this therapeutic model has brought to our understanding and management of chronic pain. Current evidence on efficacy of CBT for chronic pain is then reviewed, followed by a critical consideration of the advantages and disadvantages of the new hybrid treatment approach that conceptualises and treats chronic pain in connection with its comorbidities. Recent progress made in the area of pain and insomnia is highlighted as an example to project therapeutic innovations in the near future. Copyright © 2017 Elsevier Inc. All rights reserved.

    This study examined the content of self-defining autobiographical memories in different identities in patients with Dissociative Identity Disorder (DID) and comparison groups of patients with PTSD, healthy controls, and DID simulators. Consistent with the DID trauma model, analyses of objective ratings showed that DID patients in trauma identities retrieved more negative and trauma-related self-defining memories than DID patients in avoidant identities. Inconsistent with the DID trauma model, DID patients' self-rated trauma-relatedness of self-defining memories and future life goals did not differ between trauma identities and trauma avoidant identities. That is, the DID patients did not seem to be "shut off" from their trauma while in their avoidant identity. Furthermore, DID patients in both identities reported a higher proportion of avoidance goals compared to PTSD patients, with the latter group scoring comparably to healthy controls. The simulators behaved according to the instructions to respond differently in each identity (i.e., to report memories and goals consistent with the identity tested). The discrepant task behavior by DID patients and simulators indicated that DID patients did not seem to intentionally produce the hypothesized differences in performance between identities. In conclusion, for patients with DID (i.e., in both identities) and patients with PTSD, trauma played a central role in the retrieval of self-defining memories and in the formulation of life goals.

    2009-12-01

    Many physicians in primary care and medical/surgical specialties will care for female patients with pelvic floor disorders (PFD). A survey was mailed to 266 United States and Canadian clerkship directors that queried how medical students were being educated in PFD. Forty-four percent of clerkship directors responded. The mean clerkship size was 105 medical students. Over 97% of third year medical students received lectures on hypertension in pregnancy, normal labor, and abnormal uterine bleeding and at least 90% received lectures on obstetric hemorrhage, placenta previa, and menstruation. Forty percent to 85% of medical students received lectures in PFD depending on the topic. Eighty percent of medical students had no exposure to PFD during their first 2 years of medical school. During their third year, 95% of the students were exposed to PFD topics but only 60% had an opportunity to spend at least a day in an urogynecology practice. Clerkship directors indicate that PFD are relevant to medical student training, however, they have limited time in the clerkship to cover all of the required topics. We are missing an important opportunity to educate future clinicians about PFD, which dramatically impact women's quality of life.

    Conduct disorder (CD) causes high financial and social costs, not only in affected families but across society, with only moderately effective treatments so far. There is consensus that CD is likely caused by the convergence of many different factors, including genetic and adverse environmental factors. There is ample evidence of gene-environment interactions in the etiology of CD on a behavioral level regarding genetically sensitive designs and candidate gene-driven approaches, most prominently and consistently represented by MAOA. However, conclusive indications of causal GxE patterns are largely lacking. Inconsistent findings, lack of replication and methodological limitations remain a major challenge. Likewise, research addressing the identification of affected brain pathways which reflect plausible biological mechanisms underlying GxE is still very sparse. Future research will have to take multilevel approaches into account, which combine genetic, environmental, epigenetic, personality, neural and hormone perspectives. A better understanding of relevant GxE patterns in the etiology of CD might enable researchers to design customized treatment options (e.g. biofeedback interventions) for specific subgroups of patients.

    This study was designed to reveal the correlationship between the internal derangement state of TMJ and clinical characteristics including pain and mandibular dysfuntion. One hundred and twenty five subjects with TMJ signs and symptoms were chosen for two years. The level of pain and mandibular dysfuntion were evaluated by Visual Analog Scale (VAS) and Craniomandibular Index (CMI). The diagnostic categories of TMJ internal derangement were determined by arthrography and they included normal disc position, anterior disc displacement with reduction (ADDR), rotational disc displacement with reduction (RDDR), andterior disc displacement without reduction (ADDNR), and rotational disc displacement without reduction (RDDNR). Also disc perforation was used as a criteria to divide the diagnostic subgroups. The obtained results were as follows ; 1. The patient distribution of each group was 5 in normal disc position (4%), 40 in ADDR (32%), 30 in RDDR (24%), 34 in ADDNR (27%), and 16 in RDDNR (13%). 2. Perforation was observed in 8% of ADDR, 10% of RDDR, 32% of ADDNR, and 19% of RDDNR. 3. CMI of perforation group was higher than that of reduction or normal group(p 0.05).

    Thirty one patients with internal derangement of the TMJ and 12 subjects with normal TMJ were selected and their MR imaging and border movements of the mandible were recorded. In addition, the relationship between them were examined. In this study, the disk position and configuration in MR findings were classified as follows. Disk position: superior, anterior and anterolateral (medial and lateral were omitted), grade of anterior disk displacement (with and without reduction): slight, moderate and severe, disk configuration: biconcave, enlargement of posterior band, even thickness and biconvex. Border movements of the mandible were influenced not only by unilateral or bilateral interior derangement but also by with or without reduction of the disk. Border movements in patients with anterolateral disk displacement were more severely restricted than those with anterior disk displacement. Border movements were remarkably limited in patients with slight disk displacement, especially in unilateral cases with reduction of the disk. Border movements in patients with even thickness and biconvex types of disk configuration were a little restricted and rather similar to those of normal subjects. There was significant correlation between border movements and disk position and configuration. It means that measurement of the mandibular movements is very significant to diagnose the condition of internal derangements of the TMJ. (author)

  10. Maresin 1 Inhibits TRPV1 in Temporomandibular Joint-Related Trigeminal Nociceptive Neurons and TMJ Inflammation-Induced Synaptic Plasticity in the Trigeminal Nucleus

    Full Text Available In the trigeminal system, disruption of acute resolution processing may lead to uncontrolled inflammation and chronic pain associated with the temporomandibular joint (TMJ. Currently, there are no effective treatments for TMJ pain. Recently, it has been recognized that maresin 1, a newly identified macrophage-derived mediator of inflammation resolution, is a potent analgesic for somatic inflammatory pain without noticeable side effects in mice and a potent endogenous inhibitor of transient receptor potential vanilloid 1 (TRPV1 in the somatic system. However, the molecular mechanisms underlying the analgesic actions of maresin 1 on TMJ pain are unclear in the trigeminal system. Here, by performing TMJ injection of a retrograde labeling tracer DiI (a fluorescent dye, I showed that maresin 1 potently inhibits capsaicin-induced TRPV1 currents and neuronal activity via Gαi-coupled G-protein coupled receptors in DiI-labeled trigeminal nociceptive neurons. Further, maresin 1 blocked TRPV1 agonist-evoked increases in spontaneous excitatory postsynaptic current frequency and abolished TMJ inflammation-induced synaptic plasticity in the trigeminal nucleus. These results demonstrate the potent actions of maresin 1 in regulating TRPV1 in the trigeminal system. Thus, maresin 1 may serve as a novel endogenous inhibitor for treating TMJ-inflammatory pain in the orofacial region.

    Full Text Available Although psychological interventions might have a tremendous potential for the prevention of mental health disorders (MHD, their current impact on the reduction of disease burden is questionable. Possible reasons include that it is not practical to deliver those interventions to the community en masse due to limited health care resources and the limited availability of evidence-based interventions and clinicians in routine practice, especially in rural areas. Therefore, new approaches are needed to maximize the impact of psychological preventive interventions. Limitations of traditional prevention programs could potentially be overcome by providing Internet- and mobile-based interventions (IMIs. This relatively new medium for promoting mental health and preventing MHD introduces a fresh array of possibilities, including the provision of evidence-based psychological interventions that are free from the restraints of travel and time and allow reaching participants for whom traditional opportunities are not an option. This article provides an introduction to the subject and narratively reviews the available evidence for the effectiveness of IMIs with regard to the prevention of MHD onsets. The number of randomized controlled trials that have been conducted to date is very limited and so far it is not possible to draw definite conclusions about the potential of IMIs for the prevention of MHD for specific disorders. Only for the indicated prevention of depression there is consistent evidence across four different randomized trial trials. The only trial on the prevention of general anxiety did not result in positive findings in terms of eating disorders (EDs, effects were only found in post hoc subgroup analyses, indicating that it might be possible to prevent ED onset for subpopulations of people at risk of developing EDs. Future studies need to identify those subpopulations likely to profit from preventive. Disorders not examined so far include

Limitations of traditional prevention programs could potentially be overcome by providing Internet- and mobile-based interventions (IMIs). This relatively new medium for promoting mental health and preventing MHD introduces a fresh array of possibilities, including the provision of evidence-based psychological interventions that are free from the restraints of travel and time and allow reaching participants for whom traditional opportunities are not an option. This article provides an introduction to the subject and narratively reviews the available evidence for the effectiveness of IMIs with regard to the prevention of MHD onsets. The number of randomized controlled trials that have been conducted to date is very limited and so far it is not possible to draw definite conclusions about the potential of IMIs for the prevention of MHD for specific disorders. Only for the indicated prevention of depression there is consistent evidence across four different randomized trial trials. The only trial on the prevention of general anxiety did not result in positive findings in terms of eating disorders (EDs), effects were only found in post hoc subgroup analyses, indicating that it might be possible to prevent ED onset for subpopulations of people at risk of developing EDs. Future studies need to identify those subpopulations likely to profit from preventive. Disorders not examined so far include substance use

    Full Text Available Temporomandibular dysfunction (TMD is considered to be associated with imbalance of the whole body. This study aimed to evaluate the influence of TMD therapy on cervical spine range of movement (ROM and reduction of spinal pain. The study group consisted of 60 patients with TMD, cervical spine pain, and limited cervical spine range of movements. Subjects were interviewed by a questionnaire about symptoms of TMD and neck pain and had also masticatory motor system physically examined (according to RDC-TMD and analysed by JMA ultrasound device. The cervical spine motion was analysed using an MCS device. Subjects were randomly admitted to two groups, treated and control. Patients from the treated group were treated with an occlusal splint. Patients from control group were ordered to self-control parafunctional habits. Subsequent examinations were planned in both groups 3 weeks and 3 months after treatment was introduced. The results of tests performed 3 months after the beginning of occlusal splint therapy showed a significant improvement in TMJ function (P>0.05, cervical spine ROM, and a reduction of spinal pain. The conclusion is that there is a significant association between TMD treatment and reduction of cervical spine pain, as far as improvement of cervical spine mobility.

    The author analysed the interrelation between the morphologic changes of bone structures and the position of condylar head from the routine radiographs of 134 cases of the temporomandibular joint arthrosis. The frequencies of coincidence between the site of bone deformity and condylar head positional change were examined. Also, the positional changes of condylar head and the direction of condylar movement in relation to the kind of bone deformities were observed. The results obtained were as follows; 1. In 52.65 per cent of total cases, the site of positional change of condylar head was coincided with the site of bone deformans. The frequencies of the coincidence between these in the five items among seven items examined were above 53 per cent. From the results, it seems that the positional changes of condylar head were related with the morphological change of bone structure. 2. Eburnation and erosion revealed frequently positional changes in the opening and closing position of the mouth, although in the early stages of the TMJ arthrosis. 3. In the bone deformans, during open position of the mouth 44.81 per cent of total cases revealed backward movement and 37.74 per cent showed forward movement. In closed position of the mouth, downward movement was revealed in 35.23 percent of total cases and upward movement 28.41 percent of total cases.

    Computed tomography (CT) has a good resolution capacity and is an excellent method for measuring tissue densities. The aim here was to compare the densities and sizes of the main masticatory muscles, the masseter, medial pterygoid and lateral pterygoid muscles, as obtained with CT, with clinical findings in patients with TMJ dysfunction (25) and controls (29). The densities of the masseter muscles and the medial pterygoid muscles showed no statistical difference between the patients and controls, while the lateral pterygoid muscles of the patients had densities that were only almost significantly higher than those of the controls. The masseter muscles on the patients who more often had signs of bruxism in their dentition were statistically significantly thicker than in the controls, but the widths of the medial pterygoid muscles gave no statistical difference between the groups. The results seem to indicate that in addition to the bone density changes associated with functional disorders of the masticatory system, there may be also density and size changes in the masticatory muscles which are detectable by CT.

    The aim of this study was to investigate dentist's approaches to the use of splint therapy for myofascial pain, bruxism, and temporomandibular joint (TMJ) disorders and to assessment of treatment modalities. A 12-item questionnaire was developed to determine dentists' knowledge of TMJ disorders and approaches for occlusal splint treatments. The researchers spoke with each dentist included in the study at his/her clinic or by telephone to assess their immediate knowledge and approach to the TMJ disorders. Chi-squared test was performed to analyze the values. The confidence interval was set as 95%. A total of 370 dentists working in Turkey were participated in this study. The most common splint application reason for occlusal splint treatment was bruxism (77.8%) while TMJ pain was very rare (%1.4). The use of hard splint ratios for 0-5 years of professional experience was 57.0%, 42.4.0%, and 26.8% for the experience of 5-15 years and over 15 years groups, respectively (P < 0.001). While the dentists' with sufficient knowledge soft splint application rates were 11.6%, hard splint application rates were 43.4% for the dentists with sufficient knowledge. Occlusion adjustment rate of dentists who practice in all three groups was under 16.0%. The knowledge of the dentists about TMJ disorders and occlusal splint therapy were found to be insufficient. Their knowledge decreased with increasing experience.

    Depression, anxiety, and psychotic disorders have been associated with an increased risk of coronary heart disease (CHD). It is unclear whether this association between mental health and CHD is present across a wider range of mental disorders. Participants were 1 107 524 Swedish men conscripted at a mean age of 18.3 years. Mental disorders were assessed by psychiatric interview on conscription, and data on hospital admissions for mental disorder and CHD were obtained from national registers during 22.6 years of follow-up. An increased risk of incident CHD was evident across a range of mental disorders whether diagnosed at conscription or on later hospital admission. Age-adjusted hazard ratios (95% confidence intervals) according to diagnoses at conscription ranged from 1.30 (1.05, 1.62) (depressive disorders) to 1.90 (1.58, 2.38) (alcohol-related disorders). [corrected]. The equivalent figures according to diagnoses during hospital admission ranged from 1.49 (1.24-1.80) (schizophrenia) to 2.82 (2.53-3.13) (other substance use disorders). Associations were little changed by adjustment for parental socioeconomic status, or body mass index, diabetes mellitus, and blood pressure measured at conscription, but they were partially attenuated by the adjustment for smoking, alcohol intake, and intelligence measured at conscription, and for education and own socioeconomic position. Increased risk of incident CHD is present across a range of mental disorders and is observable when the disorders are diagnosed at a young age.

    N-acetylcysteine (NAC) is widely known for its role as a mucolytic and as an antidote to paracetamol overdose. There is increasing interest in the use of NAC in the treatment of several psychiatric disorders. The rationale for the administration of NAC in psychiatric conditions is based on its role as a precursor to the antioxidant glutathione, and its action as a modulating agent of glutamatergic, dopaminergic, neurotropic and inflammatory pathways. Areas covered: This study reviews the available data regarding the use of NAC in different psychiatric disorders including substance use disorders, autism, obsessive-compulsive spectrum disorders, schizophrenia, depression, bipolar disorder. Promising results were found in trials testing the use of NAC, mainly as an add-on treatment, in cannabis use disorder in young people, depression in bipolar disorder, negative symptoms in schizophrenia, and excoriation (skin-picking) disorder. Despite initial optimism, recent findings regarding NAC efficacy in autism have been disappointing. Expert opinion: These preliminary positive results require further confirmation in larger samples and with longer follow-ups. Given its high tolerability and wide availability, NAC represents an important target to investigate in the field of new adjunctive treatments for psychiatric conditions.

    Full Text Available Iodine deficiency disorders (IDDs have been recognized as one of the major nutritional disorders throughout the world affecting 200 million people who are at risk and another 71 million suffering from goiter and other IDDs. These groups of disorders can affect every stage of life, but most vulnerable age group is between 6 and 12 years and these disorders together constitute the single largest preventable cause of brain damage leading to learning disabilities and psychomotor impairment. The existence of endemic goiter in an extensive belt along the southern slopes of the Himalayas, Alps, and Andes has long been described, but consistently high prevalence of IDDs outside the endemic zones and failure to attain goals set by the National Iodine Deficiency Disorder Control Program questions the strategy and achievements till date. Therefore, the present article is an attempt to critically examine the program since inception in India.

    Accurate simulation and evaluation of mandibular movement is fundamental for the analysis of functional changes and effects of the mandible and maxilla before and after surgical treatments. We applied principal axes of inertia to the three-dimensional (3D) trajectories generated by patient-specific simulations of TMJ movements for the functional evaluations of mandible movement. Three-dimensional movements of the mandible and the maxilla were tracked based on a patient-specific splint and an optical tracking system. The dental occlusion recorded on the sprint provided synchronization for initial movement in the tracking and the simulation phases. The translation and rotation recorded during movement tracking was applied sequentially to the mandibular model in relation to a fixed maxilla model. The sequential 3D positions of selected landmarks on the mandible were calculated based on the reference coordinate system. The landmarks selected for analysis were bilateral condyles and pogonion points. The moment of inertia tensor was calculated with respect to the 3D trajectory points. Using the unit vectors along the principal axes derived from the tensor matrix, α, β and γ rotations around z-, y- and x-axes were determined to represent the principal directions as principal rotations respectively. The γ direction showed the higher standard deviation, variation of directions, than other directions at all the landmarks. The mandible movement has larger kinematic redundancy in the γ direction than α and β during mouth opening and closing. Principal directions of inertia would be applied to analyzing the changes in angular motion of trajectories introduced by mandibular shape changes from surgical treatments and also to the analysis of the influence of skeletal deformities on mandibular movement asymmetry.

    Full Text Available Purpose. We evaluated the efficacy of arthrocentesis in the treatment of temporomandibular joint (TMJ disorders. Material and Methods. In this prospective clinical case series, 30 consecutive patients with TMJ disorders underwent arthrocentesis using saline and sodium hyaluronate injections. Outcome measures were TMJ pain, maximum mouth opening (MMO, joint noises, and anatomical changes in the TMJ architecture. Patients were evaluated using cone-beam computed tomography (CBCT and magnetic resonance imaging (MRI at the beginning of treatment and 60 days after the last arthrocentesis. Pretreatment and posttreatment clinical parameters were compared using paired and unpaired t-tests, and McNemar’s test was used to evaluate CBCT and MRI changes (. Results. At 1-year follow-up examinations, visual analogue scale scores indicated that pain was reduced significantly and mean postoperative MMO was increased significantly. CBCT findings showed no significant change, and MRI showed only slight reductions in inflammatory signs. Conclusions. Within the limitations of this study, we can conclude that arthrocentesis is a simple, minimally invasive procedure with a relatively low risk of complications and significant clinical benefits in patients with TMJ disorders. This trial is registered with NCT01903512.

  11. Update on Psychological Trauma, Other Severe Adverse Experiences and Eating Disorders: State of the Research and Future Research Directions.

    Trottier, Kathryn; MacDonald, Danielle E

    2017-08-01

    This paper provides an updated review of the literature on the relationship between psychological trauma exposure, other severe adverse experiences, and eating disorders. Trauma exposure and other severe adverse experiences (e.g., emotional abuse) in both childhood and adulthood are associated with eating disorders. The relationship between traumatic and other adverse experiences and eating disorders appears to be mediated by emotional and behavioral dysregulation, as well as by cognitive factors such as self-criticism. Biological vulnerabilities may also be relevant to this relationship. Overall, the literature is limited by predominantly cross-sectional designs. There is clear evidence of a correlational relationship between trauma exposure and other severe adverse events, and eating disorders. Both risk and maintenance factor hypotheses have been put forth; however, prospective research testing these hypotheses remains limited. Future research should use prospective designs and focus on trauma-related symptoms (rather than trauma exposure) in order to advance research on risk and maintaining factors for eating disorders and inform treatment directions.

    2014-09-01

    The latest edition of the Diagnostic and Statistical Manual (DSM-5) has introduced new provisions for caffeine-related disorders. Caffeine Withdrawal is now an officially recognized diagnosis, and criteria for caffeine use disorder have been proposed for additional study. caffeine use disorder is intended to be characterized by cognitive, behavioral, and physiological symptoms indicative of caffeine use despite significant caffeine-related problems, similar to other Substance Use Disorders. However, since nonproblematic caffeine use is so common and widespread, it may be difficult for some health professionals to accept that caffeine use can result in the same types of pathological behaviors caused by alcohol, cocaine, opiates, or other drugs of abuse. Yet there is evidence that some individuals are psychologically and physiologically dependent on caffeine, although the prevalence and severity of these problems is unknown. This article reviews the recent changes to the DSM, the concerns regarding these changes, and some potential impacts these changes could have on caffeine consumers.

    Histamine and its receptors were first described as part of immune and gastrointestinal systems, but their presence in the central nervous system and importance in behavior are gaining more attention. The histaminergic system modulates different processes including wakefulness, feeding, and learning and memory consolidation. Histamine receptors (H1R, H2R, H3R, and H4R) belong to the rhodopsin-like family of G protein-coupled receptors, present constitutive activity, and are subjected to inverse agonist action. The involvement of the histaminergic system in brain disorders, such as Alzheimer's disease, schizophrenia, sleep disorders, drug dependence, and Parkinson's disease, is largely studied. Data obtained from preclinical studies point antagonists of histamine receptors as promising alternatives to treat brain disorders. Thus, clinical trials are currently ongoing to assess the effects of these drugs on humans. This review summarizes the role of histaminergic system in brain disorders, as well as the effects of different histamine antagonists on animal models and humans.

    To investigate whether children with Attention Deficit/Hyperactivity Disorder have lower levels of Vitamin D3 at birth than matched controls. Umbilical cord blood samples collected at birth from 202 children later diagnosed with Attention Deficit/Hyperactivity Disorder were analysed for vitamin D content and compared with 202 matched controls. 25-OH vitamin D3 was analysed by liquid chromatography tandem mass spectrometry. No differences in cord blood vitamin D concentration were found between children with Attention Deficit/Hyperactivity Disorder (median 13.0 ng/ml) and controls (median 13.5 ng/ml) (p = 0.43). In a logistic regression analysis, Attention Deficit/Hyperactivity Disorder showed a significant association with maternal age (odds ratio: 0.96, 95% confidence interval: 0.92-0.99) but not with vitamin D levels (odds ratio: 0.99, 95% confidence interval: 0.97-1.02). We found no difference in intrauterine vitamin D levels between children later developing Attention Deficit/Hyperactivity Disorder and matched control children. However, the statistical power of the study was too weak to detect an eventual small to medium size association between vitamin D levels and Attention Deficit/Hyperactivity Disorder.

  16. How invasive is TMJ double-contrast arthrography in combination with cinematography? Patient discomfort versus known diagnostic gain.

    1990-04-01

    There is no doubt that double-contrast TMJ fluoroscopic tomography enables a differential diagnosis and treatment in internal derangement pathosis. Its indication is, apart from the expected diagnostic gain, also determined by the degree of its invasiveness, and other alternative diagnostics being available (nuclear magnetic resonance). Data on patient discomfort and complications were gathered in 63 arthrotomographies; pain sensations and mandibular mobility, during and after the procedure in particular, were studied. We consider, along with Westesson, the procedure to be less invasive than commonly considered, once the surgeon-radiologist has gained enough experience.

    The purpose of this article is to review recent literature examining the occurrence of psychotic experiences in normal population and those with personality disorders. Up to 15% of individuals in the general population report some type or degree of psychotic experience. Most of these individuals function adequately, do not require psychiatric treatment and do not receive diagnosis of a psychotic illness. A significant number of individuals diagnosed with borderline personality disorder (25-50%) also report psychotic symptoms. These are not easily differentiated from the psychotic symptoms reported by individuals with schizophrenia, nor are they always transient. However, emerging research has confirmed that individuals with schizotypal personality disorder are dimensionally related to those with schizophrenia and are at an increased risk of transition to psychosis. Psychotic symptoms are best considered as 'trans-diagnostic' entities on a continuum from normal to pathological. There is a large body of evidence for a dimensional relationship between schizotypal personality disorder and schizophrenia. There is also a significant amount of research showing that psychotic symptoms in borderline personality disorder are frequent, nontransient and represent a marker of illness severity. This review highlights the need to move beyond traditional assumptions and categorical boundaries when evaluating psychotic experiences and psychopathological phenomena.

    Aims: Whiplash injury to the neck, is often considered a significant risk factor for development of temporomandibular disorders (TMD), and has been proposed to produce internal derangements of the temporomandibular joint (TMJ). Few studies however have examined TMD-related pain in acute whiplash...... patients compared with a matched control group. The aim of the present study was to assess pain and sensorimotor function in the craniofacial region in an unselected group of patients sustaining a motor vehicle accident involving a rear collision. Methods: Prospectively, 19 acute whiplash patients exposed...... obtained at each visit. Results: One whiplash patient and I ankle-injury patient bad jaw pain at the first visit. Palpation scores of the TMJ and the summated palpation scores only tended to be higher in patients sustaining a whiplash injury than in ankle-injury controls at the first visit. However, MPQ...

    According to the recent changes of working environments and socio-economical conditions, the proportion of working women are increasing in Japan. Characteristics of occupational workload and stress of Japanese working women are consistent with those in many industrialized countries except man-dominant culture. In this review we describe the history, current issues, and future research directions on occupational health of working women, especially focused on reproductive health, work-related musculo-skeletal disorders (WMSDs), and mental disorders. In the reproductive health survey, traditionally main concern was about pregnancy outcomes, then fecundity studies, such as time to pregnancy, became topics recently. Future research will be shifted to outcomes not only during pregnancy but also disorders of hormonal balance and climacterium or health conditions after menopause. WMSDs are reviewed on mainly gender difference and its causative factors. Historically, mental health of working women in Japan has focused on the job stress of nurses. We compare results with a lot of recent researches in Europe and U.S.A., where interaction between occupational stress and family roles were studied. It is not easy to predict the prospective status of female workers in Japan, but social, workplace and familial supports will enhance their health promotion.

    Bipolar I and II disorder are chronic and severe psychiatric illnesses that affect many women. Furthermore, women are at increased risk for mood episodes during the postpartum period compared with non-postpartum periods. Unfortunately, identification of clinically significant depressive or (hypo)manic episodes can be challenging. Delays in detection, as well as misdiagnosis, put women at risk of many negative consequences, such as symptom exacerbation and treatment refractoriness. Early and accurate detection of bipolar I or II disorder in the postpartum period is critical to improve prognosis. At this time, limited recommendations can be made due to a paucity of research. Further research on postpartum bipolar I or II disorder focusing on its identification, consequences and treatment is urgently needed to allow for empirically informed clinical decision-making.

    The objective of this study was to evaluate the impact of clinical TMJ diagnosis, gender, and age on the agreement between expected and actual radiographic findings. A total of 204 patients with TMJ symptoms were examined using the Research Diagnostic Criteria (RDC/TMD). Expected radiographic findings were recorded. TMJ tomograms in closed and open mouth position were assessed for osseous changes and condyle position. Expected and actual findings were compared. Logistic regression analyses were performed with agreement on radiographic findings as the dependent variable and with clinical RDC/TMD diagnoses, gender and age as the independent variables. The number of radiographic findings was mostly underestimated. A clinical diagnosis of osteoarthritis and age increased the chance of overestimating osseous changes. Disc displacement and age decreased the chance of agreement on certain condyle positions. Tomography often revealed unexpected findings. It was not possible to select particular patient groups who would benefit more or less from a radiographic examination.

    To present the descriptive data on the frequency of medical and psychiatric morbidity and also to discuss various pertinent issues relevant to the disaster management, the future challenges and psychosocial needs of the 2013 floods in Uttarakhand, India. Observation was undertaken by the disaster management team of National Institute of Mental Health and Neurosciences in the worst affected four districts of Uttarakhand. Qualified psychiatrists diagnosed the patients using the International Classification of Diseases-10 criteria. Data were collected by direct observation, interview of the survivors, group sessions, individual key-informant interview, individual session, and group interventions. Patients with physical health problems formed the majority of treatment seekers (39.6%) in this report. Only about 2% had disaster induced psychiatric diagnoses. As was expected, minor mental disorders in the form of depressive disorders and anxiety disorders formed majority of the psychiatric morbidity. Substance use disorders appear to be very highly prevalent in the community; however, we were not able to assess the morbidity systematically. The mental health infrastructure and manpower is abysmally inadequate. There is an urgent need to implement the National Mental Health Program to increase the mental health infrastructure and services in the four major disaster-affected districts.

    Objective: : The purpose of this study is to determine the prevalence of radiographic presence of otomastoiditis while examining temporomandibular joint (TMJ) disorders in magnetic resonance images (MRI) in a series of 2270 temporomandibular joint magnetic resonance images and to examine the relationship between otomastoiditis and TMJ disorders. Materials and methods: : 2270 temporomandibular joint magnetic resonance images and patients' data were retrospectively investigated. Magnetic resonance images were obtained from the patients who referred to Osaka University Dental Hospital Outpatient Clinic with TMJ complaints for the last four years (from January 1998 to January 2003). The patients, who were diagnosed as otomastoiditis based on their temporomandibular joint magnetic resonance images, were sent to Osaka University Hospital Department of Otolaryngology for a medical consultation in order to have their pathologies certified following their MR process. Age and sex were recorded for all patients and for otomastoiditis cases; location of the disease, symptoms of patients and TMJ findings were noted as well. Results: : Seven patients were diagnosed as acute otomastoiditis and one patient diagnosed as chronic active otitis media with cholesteatoma in the series of 2270 MR, which were representing a prevalence of 0.39%. Neurilemoma diagnosed in left mastoid process in one patient. The final diagnoses of all patients were made after medical consultation. Conclusion: : While examining temporomandibular joint magnetic resonance images; it is not only important to examine just the TMJ structures, but also to look at the nearby anatomical features to check evidence for inflammatory disease.

    The aim of this work was to gather clinical data on craniomandibular (CMD)/temporomandibular joint (TMJ) disorders in a paediatric population. The clinical study population comprised patients with TMJ disorders who were being treated in the orthognathic ambulatory clinic of the University of Naples, where an instrumental and clinical study was performed. Data were recorded for extra and intraoral findings, Angles classification and malocclusions. Radiographic examinations were carried out. Study models were fabricated for evaluation. TMJs were assessed by palpation as well as masseter, temporal, suprahyoid, sternocleidomastoid, suboccipital, paravertebral and trapezius muscles to evaluate any possible pain. Auscultation of the TMJ was used to determine presence of articular sounds and their type (cracks, crunches, clicks) by the use of a stethoscope. Pain localisation was evaluated according to these movements taking into account site, intensity, frequency, and duration. Episodes of headache were recorded according to its intensity (mild, moderate, intense), frequency (daily, weekly, monthly), site (top of the head, occiput, temple, frontal, overorbital region, back of the head) and the duration of the episodes (in minutes, hours or whether constant). A substantial number of the 106 patients included in the study showed a malocclusion with prevalence in Angles Class II cases. Bruxism, onychophagy, TMJ pain, headache, mouth opening partial inability, mastication difficulty and articular sound were the most representative symptoms. The identification and recognition of factors, such as malocclusions and parafunctions, are considered fundamental to early diagnosis of TMJ problems, which is the most useful way to avoid a dysfunctional state of the stomatognathic system.

    Individuals with post-traumatic stress disorder (PTSD) tend to retrieve autobiographical memories with less episodic specificity, referred to as overgeneralised autobiographical memory. In line with evidence that autobiographical memory overlaps with one's capacity to imagine the future, recent work has also shown that individuals with PTSD also imagine themselves in the future with less episodic specificity. To date most studies quantify episodic specificity by the presence of a distinct event. However, this method does not distinguish between the numbers of internal (episodic) and external (semantic) details, which can provide additional insights into remembering the past and imagining the future. This study employed the Autobiographical Interview (AI) coding scheme to the autobiographical memory and imagined future event narratives generated by combat veterans with and without PTSD. Responses were coded for the number of internal and external details. Compared to combat veterans without PTSD, those with PTSD generated more external than internal details when recalling past or imagining future events, and fewer internal details were associated with greater symptom severity. The potential mechanisms underlying these bidirectional deficits and clinical implications are discussed.

    Metabolic disorders, including type 2 diabetes (T2DM) and cardiovascular disease (CVD), present an increasing public health concern and can significantly undermine an individual's quality of life. The relative risk of CVD, the primary cause of death in T2DM patients, is two to four times higher in people with T2DM compared with those who are non-diabetic. The prevalence of metabolic disorders has been associated with dynamic changes in dietary macronutrient intake and lifestyle changes over recent decades. Recently, the scientific community has considered alteration in gut microbiota composition to constitute one of the most probable factors in the development of metabolic disorders. The altered gut microbiota composition is strongly conducive to increased adiposity, β-cell dysfunction, metabolic endotoxemia, systemic inflammation, and oxidative stress. Probiotics and prebiotics can ameliorate T2DM and CVD through improvement of gut microbiota, which in turn leads to insulin-signaling stimulation and cholesterol-lowering effects. We analyze the currently available data to ascertain further potential benefits and limitations of probiotics and prebiotics in the treatment of metabolic disorders, including T2DM, CVD, and other disease (obesity). The current paper explores the relevant contemporary scientific literature to assist in the derivation of a general perspective of this broad area.

  12. Smoking, nicotine and psychiatric disorders: evidence for therapeutic role, controversies and implications for future research.

    1999-02-01

    Researchers interested in investigating the possible therapeutic effects and the mechanisms of action of nicotine in neuropsychiatric disorders face a social-scientific-ethical dilemma. This dilemma comprises three components: (1) the known addictive potential of nicotine makes careful evaluation of the therapeutic potential of this compound socially unattractive; (2) the potential misuse of scientifically determined data by the tobacco 'lobby' creates ethical concerns; and (3) the possible confusion between the differential effects of nicotine in human smokers versus non-smokers creates difficulties in study designs in voluntary human subjects. Therefore, it is imperative that, at the onset of this review, the authors stress that they do not advocate cigarette-smoking as a route of nicotine intake under any circumstances on the basis that controlled dosing of nicotine may be of potential benefit in some neuropsychiatric disorders. In this article, we review the psychopharmacology of nicotine and its effects in a variety of neuropsychiatric disorders including schizophrenia, depression, anxiety and Tourette's syndrome. Possible mechanisms of action of nicotine directly or indirectly via its interaction with other neurotransmitter systems (i.e. serotonin, dopamine and noradrenaline) in relation to its potential role in these disorders are discussed. It is postulated that new drugs may need to be developed that selectively interact with nicotinic receptors without addiction potential.

  14. Newborn screening of inherited metabolic disorders by tandem mass spectrometry: past, present and future

    Directory of Open Access Journals (Sweden)

    G. Scaturro

    2013-04-01

    Full Text Available Inborn errors of metabolism are inherited biochemical disorders caused by lack of a functional enzyme, transmembrane transporter, or similar protein, which then results in blockage of the corresponding metabolic pathway. Taken individually, inborn errors of metabolism are rare. However, as a group these diseases are relatively frequent and they may account for most of neonatal mortality and need of health resources. The detection of genetic metabolic disorders should occur in a pre-symptomatic phase. Recently, the introduction of the tandem mass spectrometric methods for metabolite analysis has changed our ability to detect intermediates of metabolism in smaller samples and provides the means to detect a large number of metabolic disorders in a single analytical run. Screening panels now include a large number of disorders that may not meet all the criteria that have been used as a reference for years. The rationale behind inclusion or exclusion of a respective disorder is difficult to understand in most cases and it may impose an ethical dilemma. The current organization is an important tool of secondary preventive medicine, essential for children’s healthcare, but the strong inhomogeneity of the regional models of screening applied today create in the Italian neonatal population macroscopic differences with regards to healthcare, which is in effect mainly diversified by the newborn’s place of birth, in possible violation of the universal criterion of the equality of all citizens. Carefully weighed arguments are urgently needed since patient organizations, opinion leaders and politicians are pressing to proceed with expansion of neonatal population screening.

    The origin of altered radiotracer uptake and distribution in functional brain imaging studies, often considered to reflect regional cerebral blood flow (rCBF), in psychiatric disorders is unknown. Interpreting the magnitude of changes as changes in the magnitude of neuronal activity may be reasonable during normal circumstances, but less reliable in pathologic states. Results of published 99mTc-HMPAO SPECT studies in unmedicated patients with schizophrenia and major depression are discussed in the light of 99mTc-HMPAO properties, and reported findings of altered cell morphology and biochemistry, with emphasis on energy metabolism. We conclude that the SPECT technique using radiotracers with known biochemical properties will become useful in the understanding of cellular dysfunctions at different phases of neuropsychiatric disorders, and that use of automatic interpretation of three-dimensional volumes will allow for easier identification of regional neural correlates of the different psychiatric symptoms (Au)

    Generalized, persistent, and free-floating anxiety was first described by Freud in 1894. The diagnostic term generalized anxiety disorder (GAD) was not in classification systems until the publication of the diagnostic and statistical manual for mental disorders, third edition (DSM-III) in 1980. Initially considered as a residual category to be used when no other diagnosis could be made, it is not accepted that GAD represents a distinct diagnostic category yet. Since 1980, revisions to the diagnostic criteria for GAD in the DSM-III-R, DSM-IV and DSM-5 classifications have slightly redefined this disorder. The classification is fluid. The duration criterion has increased to 6 months in DSM-IV, but decreased to 3 months in DSM-5. This article reviews the development of diagnostic criteria for defining GAD from Freud to DSM-5 and compares the DSM-5 criterion with DSM-IV and the tenth revision of the International Classification of Disease. The impact of the changes in diagnostic criteria on research into GAD, and on diagnosis, differential diagnosis, will be discussed.

    Among other approaches, the modulation of the dopaminergic pathway has been advocated in the therapeutic management of Alcohol Use Disorders (AUD). A potential avenue toward the modulation of the dopaminergic pathway across varying substance disorders seems to be provided by aripiprazole, a second-generation antipsychotic characterized by a peculiar pharmacodynamics signature. In this review, the authors provided a qualitative synthesis and a critical perspective on the efficacy of aripiprazole in relapse prevention and craving in AUD. A systematic search was carried out through MEDLINE/Embase/PsycINFO/Cochrane Library from inception until September 2015, combining free terms and MESH headings for the topics of AUD and aripiprazole as following: (((Alcohol use Disorder) OR (Alcohol use)) AND aripiprazole). Based both on a qualitative synthesis and a critical interpretation of the evidence, the authors submit that aripiprazole would promote alcohol abstinence and reduce the alcohol seeking behaviour possibly via dopaminergic and serotoninergic modulations at the fronto-subcortical circuits underpinning alcohol reward and craving, impulsive behaviour as well as reduce alcohol-related anxiety/low mood and anhedonia. However, due to the lack of published studies, a conclusive statement about any direct effect of aripiprazole in the prevention of craving and/or alcohol consumption is not possible.

    This study investigated the prevalence of Temporomandibular Disorders (TMD) in the elderly and its association with palpation of the temporomandibular joint (TMJ), masticatory and cervical muscles as well as the presence of headache and joint noises. The sample consisted of 200 elderly of both genders (mean age: 69.2±5.7 years). The clinical evaluation of TMD signs and symptoms was divided into three stages: an anamnestic questionnaire, a TMJ evaluation, and a muscular examination. The results were analyzed through descriptive statistics as well as using χ2 and the tendency tests. The presence of TMD was observed in 61% of the sample (mild: 43.5%, moderate: 13%, severe: 4.5%). A significantly greater prevalence of TMD was found for females (72.4%) compared with that for men (41.1%) (pheadaches and the presence of TMD (p=0.0001). The association between the presence of joint noises and sensitivity to TMJ palpation was not significant. The elderly presented high TMD prevalence, mostly in females, with mild severity and related to TMJ and masticatory/cervical muscles palpation. Thus, the accomplishment of a detailed clinical examination to investigate the presence of such disorders is essential and it must not be neglected during the treatment of elderly patients.

    disorders, with a focus on community-based studies of risk factors and nosology; and to point to future areas for study, notably the social and economic burden and general population "mental health literacy" of people with eating disorders. In spite of problems in identifying and recruiting sufficient numbers of people with anorexia nervosa and variable methods of case-ascertainment, studies of incidence and prevalence of eating disorders have reached a general consensus and do not in general support a current rising incidence, except possibly a small increase in anorexia nervosa in young women. The application of analytic epidemiologic methods has lead to a greater understanding of environmental and genetic factors, as compared with social and economic factors, to the risk of developing eating disorders, and as well aided the refinement of eating disorder nosology. In the future analytic epidemiology has the potential to answer key questions about the nature and determinants of eating disorders, and to help to decide how to help those who need it most.

    Impulse control disorders (ICDs) including compulsive gambling, buying, sexual behaviors, and eating occur relatively frequently in Parkinson disease (PD) with at least one ICD identified in 14% of PD patients in a large, multicenter, observational study. ICDs behaviors range widely in severity but can lead to catastrophic consequences, including financial ruin, divorce, loss of employment, and increased health risks. The main risk factor for ICDs in PD is the use of Dopamine agonists (DAs) and discontinuation of the offending agent is considered first line treatment. However, many patients do not tolerate this intervention as consequence of increased motor and psychiatric disability or appearance of DA withdrawal syndrome. In this article, we review current management strategies and emerging new interventions for treatment of ICDs in PD. Pharmacological treatment should be individualized based on patient's unique neuropsychiatric profile, social support, medical comorbidities, tolerability and motor symptoms.

    Restoration of chewing ability is an important aspect of the treatment for temporomandibular disorders (TMDs). However, too little attention has been paid to it. We have used a questionnaire to evaluate and score the chewing ability of TMD patients. The questionnaire includes 19 kinds of food and a chewing task. The patient was asked if she/he experiences difficulty in enjoying eating. The aim of this study was to evaluate correlations between score of chewing ability (SCA) and other symptoms/signs of TMD. Four hundred and seventy-three consecutive TMD patients were evaluated for SCA and other symptoms/signs including temporomandibular joint (TMJ) pain, TMJ and muscle tenderness, TMJ noise (clicking and crepitus), and maximum mouth opening. The relationship between SCA and other symptoms/signs were analysed by multiple regression analysis. Score of chewing ability correlated significantly with TMJ pain and mouth opening capacity but not with TMJ noise and muscle tenderness. Age was a background factor but sex was not. The result of this study suggests that SCA correlated with dysfunction of the TMD patients. This method could be used to evaluate the ability of chewing in assessment of TMD.

    Full Text Available This study explored attitudes toward hypothetical genetic testing for posttraumatic stress disorder (PTSD and addiction among veterans. We surveyed a random sample of community-based veterans (n = 700 by telephone. One year later, we asked the veterans to provide a DNA sample for analysis and 41.9% of them returned the DNA samples. Overall, most veterans were not interested in genetic testing neither for PTSD (61.7% nor for addiction (68.7%. However, bivariate analyses suggested there was an association between having the condition of interest and the likelihood of genetic testing on a 5-point scale (p < 0.001 for PTSD; p = 0.001 for alcohol dependence. While ordinal regressions confirmed these associations, the models with the best statistical fit were bivariate models of whether the veteran would likely test or not. Using logistic regressions, significant predictors for PTSD testing were receiving recent mental health treatment, history of a concussion, younger age, having PTSD, having alcohol dependence, currently taking opioids for pain, and returning the DNA sample during the follow-up. For addiction testing, significant predictors were history of concussion, younger age, psychotropic medication use, having alcohol dependence, and currently taking opioids for pain. Altogether, 25.9% of veterans reported that they would have liked to have known their genetic results before deployment, 15.6% reported after deployment, and 58.6% reported they did not want to know neither before nor after deployment. As advancements in genetic testing continue to evolve, our study suggests that consumer attitudes toward genetic testing for mental disorders are complex and better understanding of these attitudes and beliefs will be crucial to successfully promote utilization.

    Posttraumatic Stress Disorder (PTSD) is associated with maladaptive changes in self-identity, including impoverished perceived self-efficacy. This study examined if enhancing perceptions of self-efficacy in combat veterans with and without symptoms of PTSD promotes cognitive strategies associated with positive mental health outcomes. Prior to completing a future thinking and social problem-solving task, sixty-two OEF/OIF veterans with and without symptoms of PTSD were randomized to either a high self-efficacy (HSE) induction in which they were asked to recall three autobiographical memories demonstrating self-efficacy or a control condition in which they recalled any three autobiographical events. An interaction between HSE and PTSD revealed that individuals with symptoms of PTSD in the HSE condition generated future events with more self-efficacious statements than those with PTSD in the control condition, whereas those without PTSD did not differ in self-efficacy content across the conditions. In addition, individuals in the HSE condition exhibited better social problem solving than those in the control condition. Increasing perceptions of self-efficacy may promote future thinking and problem solving in ways that are relevant to overcoming trauma and adversity. Copyright © 2016 Elsevier Ireland Ltd.

    Manufacturers have provided C-arm CT imaging technologies for applications in interventional radiology in recent years. However, clinical imaging protocols and radiation doses have not been well studied or reported. The purpose of this study is to develop low-dose settings for clinically acceptable CT imaging of temporomandibular joint in interventional radiology suites, using a C-arm imaging angiography system. CT scans were performed with a flat-panel digital C-arm angiographic system on a 5-year-old anthropomorphic phantom. The CTDI was determined for various rotation times, dose settings and Cu filter selections. The CTDI values were compared with those of conventional low-dose CT for the same phantom. The effectiveness of using Cu filters to reduce dose was also investigated. Images were reviewed by a senior radiologist for clinical acceptance. The manufacturer's default setting gave an equivalent CTDI of 4.8 mGy. Optimizing the dose settings and adding copper filtration reduced the radiation dose by 94%. This represents a 50% reduction from conventional CT. Use of Cu filters and low-dose settings significantly reduced radiation dose from that of standard settings. This phantom study process successfully guided the clinical implementation of low-dose studies for all ages at our institution. (orig.)

    2011-01-01

    SYNOPSIS Body dysmorphic disorder (BDD), a distressing or impairing preoccupation with nonexistent or slight defect(s) in appearance, usually begins during early adolescence and appears to be common in youth. BDD is characterized by substantial impairment in psychosocial functioning and markedly high rates of suicidality. Cognitive-behavioral therapy (CBT) tailored to BDD’s unique features is the best tested and most promising psychosocial treatment for adults with BDD. CBT has been used for youth with BDD, but it has not been systematically developed for or tested in this age group, and there is a pressing need for this work to be done. This article focuses on CBT for BDD in adults and youth, possible adaptations for youth, and the need for treatment research in youth. We also discuss BDD’s prevalence, clinical features, how to diagnose BDD in youth, recommended pharmacotherapy for BDD (serotonin-reuptake inhibitors), and treatments that are not recommended (surgery and other cosmetic treatments).

    Research examining nonpharmacological interventions for adults diagnosed with attention-deficit/hyperactivity disorder (ADHD) has expanded in recent years and provides patients with more treatment options. Mindfulness-based training is an example of an intervention that is gaining promising preliminary empirical support and is increasingly administered in clinical settings. The aim of this review is to provide a rationale for the application of mindfulness to individuals diagnosed with ADHD, describe the current state of the empirical basis for mindfulness training in ADHD, and summarize a treatment approach specific to adults diagnosed with ADHD: the Mindful Awareness Practices (MAPs) for ADHD Program. Two case study examples are provided to demonstrate relevant clinical issues for practitioners interested in this approach. Directions for future research, including mindfulness meditation as a standalone treatment and as a complementary approach to cognitive-behavioral therapy, are provided. PMID:25908900

    This study aimed to test the vulnerability model of the relationship between temperament and mental disorders using a large sample of adolescents from the TRacking Adolescents Individual Lives' Survey (TRAILS). The vulnerability model argues that particular temperaments can place individuals at risk for the development of mental health problems. Importantly, the model may imply that not only baseline temperament predicts mental health problems prospectively, but additionally, that changes in temperament predict corresponding changes in risk for mental health problems. Data were used from 1195 TRAILS participants. Adolescent temperament was assessed both at age 11 and at age 16. Onset of mental disorders between age 16 and 19 was assessed at age 19, by means of the World Health Organization Composite International Diagnostic Interview (WHO CIDI). Results showed that temperament at age 11 predicted future mental disorders, thereby providing support for the vulnerability model. Moreover, temperament change predicted future mental disorders above and beyond the effect of basal temperament. For example, an increase in frustration increased the risk of mental disorders proportionally. This study confirms, and extends, the vulnerability model. Consequences of both temperament and temperament change were general (e.g., changes in frustration predicted both internalizing and externalizing disorders) as well as dimension specific (e.g., changes in fear predicted internalizing but not externalizing disorders). These findings confirm previous studies, which showed that mental disorders have both unique and shared underlying temperamental risk factors. © 2013 The Authors.

    Substance use disorders (SUDs) can be viewed as a pathology of neuroadaptation. The pharmacological overstimulation of neural mechanisms of reward, motivated learning and memory leads to drug-seeking behavior. A critical characteristic of SUDs is the appearance of craving, the motivated desire and urge to use, which is a main focus of current pharmacological and behavioral therapies. Recent proof-of-concept studies have tested the effects of noninvasive brain stimulation on craving. Although its mechanisms of action are not fully understood, this approach shows interesting potential in tuning down craving and possibly consumption of diverse substances. This article reviews available results on the use of repetitive transcranial magnetic stimulation (rTMS) and transcranial electrical stimulation (tES) in SUDs, specifically tobacco, alcohol and psychostimulant use disorders. We discuss several important factors that need to be addressed in future works to improve clinical assessment and effects of noninvasive brain stimulation in SUDs. Factors discussed include brain stimulation devices and parameters, study designs, brain states and subjects' characteristics. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Full Text Available Psychoneuroimmunology characterizes a disease entity that combines psychological components, central nervous system regulation, and immunology, to explain the etiological complexity of a disease. Temporomandibular disorders (TMDs include a heterogeneous group of painful conditions that involve the temporomandibular joint (TMJ, muscles of mastication, and the adjacent anatomic structures. This review focuses on the psychoneuroimmunological diseases and disorders that mimic the symptoms of TMDs. The differentiation of these disorders is of great significance to the oral physician - differentiating and diagnosing the cause of TMJ pain and treating it effectively to benefit the patient.The literature for this review was taken from Medline/PubMed, other indexed journals, standard text books, and online material.

    Objective This critical review appraises neuroimaging findings in bipolar disorder in emotion processing, emotion regulation, and reward processing neural circuitry, to synthesize current knowledge of the neural underpinnings of bipolar disorder, and provide a neuroimaging research “roadmap” for future studies. Method We examined findings from all major studies in bipolar disorder that used fMRI, volumetric analyses, diffusion imaging, and resting state techniques, to inform current conceptual models of larger-scale neural circuitry abnormalities in bipolar disorder Results Bipolar disorder can be conceptualized in neural circuitry terms as parallel dysfunction in bilateral prefrontal cortical (especially ventrolateral prefrontal cortical)-hippocampal-amygdala emotion processing and emotion regulation neural circuitries, together with an “overactive” left-sided ventral striatal-ventrolateral and orbitofrontal cortical reward processing circuitry, that result in characteristic behavioral abnormalities associated with bipolar disorder: emotional lability, emotional dysregulation and heightened reward sensitivity. A potential structural basis for these functional abnormalities are gray matter decreases in prefrontal and temporal cortices, amygdala and hippocampus, and fractional anisotropy decreases in white matter tracts connecting prefrontal and subcortical regions. Conclusion Neuroimaging studies of bipolar disorder clearly demonstrate abnormalities in neural circuitries supporting emotion processing, emotion regulation and reward processing, although there are several limitations to these studies. Future neuroimaging research in bipolar disorder should include studies adopting dimensional approaches; larger studies examining neurodevelopmental trajectories in bipolar disorder and at-risk youth; multimodal neuroimaging studies using integrated systems approaches; and studies using pattern recognition approaches to provide clinically useful, individual

    To evaluate the findings of normal facial nerve, as seen on oblique sagittal MRI using a TMJ (temporomandibular joint) surface coil, and then to evaluate abnormal findings of peripheral facial nerve palsy. We retrospectively reviewed the MR findings of 20 patients with peripheral facial palsy and 50 normal facial nerves of 36 patients without facial palsy. All underwent oblique sagittal MRI using a T MJ surface coil. We analyzed the course, signal intensity, thickness, location, and degree of enhancement of the facial nerve. According to the angle made by the proximal parotid segment on the axis of the mastoid segment, course was classified as anterior angulation (obtuse and acute, or buckling), straight and posterior angulation. Among 50 normal facial nerves, 24 (48%) were straight, and 23 (46%) demonstrated anterior angulation; 34 (68%) showed iso signal intensity on T1W1. In the group of patients, course on the affected side was either straight (40%) or showed anterior angulation (55%), and signal intensity in 80% of cases was isointense. These findings were similar to those in the normal group, but in patients with post-traumatic or post-operative facial palsy, buckling, of course, appeared. In 12 of 18 facial palsy cases (66.6%) in which contrast materials were administered, a normal facial nerve of the opposite facial canal showed mild enhancement on more than one segment, but on the affected side the facial nerve showed diffuse enhancement in all 14 patients with acute facial palsy. Eleven of these (79%) showed fair or marked enhancement on more than one segment, and in 12 (86%), mild enhancement of the proximal parotid segment was noted. Four of six chronic facial palsy cases (66.6%) showed atrophy of the facial nerve. When oblique sagittal MR images are obtained using a TMJ surface coil, enhancement of the proximal parotid segment of the facial nerve and fair or marked enhancement of at least one segment within the facial canal always suggests pathology of

    The aim of this study was the obtention of the absorbed doses to critical organs for evaluating and comparing the radiobiologic risks from three different TMJ radiographic techniques, using a pantomographic system, utilizing a combination of rare-earth screens to fast films. The compared techniques were the conventional panoramic technique, the Manufacture's recommended technique for TMJ and the Chilvarquer's technique. The absorber doses were measured by exposing a phantom, fitted with fluoride TLD in fourteen sites distributed at the Thyroid, Pituitary, Salivary glands sites distributed at the Thyroid, Pituitary, Salivary glands and at the bone marrow. The radiobiologic risks were calculated using the UNSCEAR 34 (1977), and the fatal cancer incidence for age and sex was calculated using the ICRP 29 (1977). Based on the obtained data, it was concluded that the Chilvarquer's technique induced the lowest absorbed doses and the estimated radiobiologic risks were lower than a cancer per a million of examinations.

    Patients suffering from major depressive disorder are more likely to suffer from alcohol use disorder. The data is inconclusive for the effectiveness of antidepressant treatment of patients suffering from both illnesses in regards to improving sobriety and reducing alcohol-related healthcare expenses such as hospitalizations. The objective of this study is to determine if a new prescription of an antidepressant upon inpatient discharge is associated with a reduction in the number of future acute alcohol-related hospital readmissions to the same institution in patients suffering from major depressive disorder and alcohol-use disorder. A retrospective, medical record review study was conducted at a publicly-supported hospital in Sylmar, CA. A query was performed for adult patients admitted between 1/1/2005-12/31/2013 who had ICD-9 codes for both alcohol-use disorder and depression. Index admission was the first hospitalization in which the patient was currently consuming alcohol and had depression as identified by physician documentation as a problem. Acute alcohol-related admissions were those for alcohol intoxication or withdrawal (indicating current alcohol use). Patients were excluded if they were receiving an antidepressant on index admission, depressive disorder with a prescription for an antidepressant is not associated with a reduction in future readmissions, nor significantly increase the number of days to readmission. The study does not support the concept of antidepressants in reducing acute alcohol-related readmissions.

    It is not known whether bone scan is useful for the prediction of the prognosis of patients with temporomandibular disorders (TMD). The aim of the present study was to identify useful prognostic markers on bone scan for the pre-therapeutic assessment of patients with unilateral TMD. Between January 2005 and July 2007, 55 patients (M:F=9:46; mean age, 34.7±14.1 y) with unilateral TMD that underwent a pre-therapeutic bone scan were enrolled. Uptake of Tc-99m HDP in each temporomandibular joint (TMJ) was quantitated using a 13X13 pixel-square region-of-interest over TMJ and parietal skull area as background. TMJ uptake ratios and asymmetric indices were calculated. TMD patients were classified as improved or not improved and the bone scan findings associated with each group were investigated. Forty-six patients were improved, whereas 9 patients were not improved. There was no significant difference between the two groups of patients regarding the TMJ uptake ratio of the involved joint, the TMJ uptake ratio of the non-involved joint, and the asymmetric index (p>0.05). However, in a subgroup analysis, the patients with an increased uptake of Tc-99m HDP at the disease-involved TMJ, by visual assessment, could be easily identified by the asymmetric index; the patients that improved had a higher asymmetric index than the patients that did not improve (1.32±0.35 vs. 1.08±0.04, p=0.023), The Tc-99m HDP bone scan may help predict the prognosis of patients with unilateral TMD after splint therapy when the TMD-involved joint reveals increased uptake by visual assessment

  6. Temporomandibular joint disorder complaints in tinnitus: further hints for a putative tinnitus subtype.

    Directory of Open Access Journals (Sweden)

    Veronika Vielsmeier

    Full Text Available OBJECTIVE: Tinnitus is considered to be highly heterogeneous with respect to its etiology, its comorbidities and the response to specific interventions. Subtyping is recommended, but it remains to be determined which criteria are useful, since it has not yet been clearly demonstrated whether and to which extent etiologic factors, comorbid states and interventional response are related to each other and are thus applicable for subtyping tinnitus. Analyzing the Tinnitus Research Initiative Database we differentiated patients according to presence or absence of comorbid temporomandibular joint (TMJ disorder complaints and compared the two groups with respect to etiologic factors. METHODS: 1204 Tinnitus patients from the Tinnitus Research Initiative (TRI Database with and without subjective TMJ complaints were compared with respect to demographic, tinnitus and audiological characteristics, questionnaires, and numeric ratings. Data were analysed according to a predefined statistical analysis plan. RESULTS: Tinnitus patients with TMJ complaints (22% of the whole group were significantly younger, had a lower age at tinnitus onset, and were more frequently female. They could modulate or mask their tinnitus more frequently by somatic maneuvers and by music or sound stimulation. Groups did not significantly differ for tinnitus duration, type of onset (gradual/abrupt, onset related events (whiplash etc., character (pulsatile or not, hyperacusis, hearing impairment, tinnitus distress, depression, quality of life and subjective ratings (loudness etc.. CONCLUSION: Replicating previous work in tinnitus patients with TMJ complaints, classical risk factors for tinnitus like older age and male gender are less relevant in tinnitus patients with TMJ complaints. By demonstrating group differences for modulation of tinnitus by movements and sounds our data further support the notion that tinnitus with TMJ complaints represents a subgroup of tinnitus with clinical

    Non-invasive positron emission tomography (PET) and single-photon emission computed tomography (SPECT) are techniques used to quantify molecular interactions, biological processes and protein concentration and distribution. In the central nervous system, these molecular imaging techniques can provide critical insights into neurotransmitter receptors and their occupancy by neurotransmitters or drugs. In recent years, there has been an increase in the number of studies that have investigated neurotransmitters in autism spectrum disorder (ASD), while earlier studies mostly focused on cerebral blood flow and glucose metabolism. The underlying and contributing mechanisms of ASD are largely undetermined and ASD diagnosis relies on the behavioral phenotype. Discovery of biochemical endophenotypes would represent a milestone in autism research that could potentially lead to ASD subtype stratification and the development of novel therapeutic drugs. This review characterizes the prior use of molecular imaging by PET and SPECT in ASD, addresses methodological challenges and highlights areas of future opportunity for contributions from molecular imaging to understand ASD pathophysiology.

    Using magnetic resonance imaging (MRI), this study aimed to evaluate the morphology of the articular disc of the temporomandibular joint (TMJ) in patients with temporomandibular disorder (TMD). There were 218 TMJ of 109 assessed patients; 88 were females and 21 males, and all were diagnosed as symptomatic for temporomandibular disorder. The articular disc positions were classified in the normal position and with anterior disc displacement with and without reduction. Regarding the morphology, the discs were classified as follows: biconcave (normal), biplanar, rounded, biconvex, folded, thickening in the posterior band, thickening in the anterior band and hemiconvex. The results indicated that females were the most affected by morphological changes of the articular disc (p = 0.008/Cramer's V = 0.295). There was no statistical significance when correlating the disc morphology with the sides (right and left). There was a significant correlation between the position and morphology of the articular disc (p < 0.001/Cramer's V = 0.609), and in the normal position of the discs presenting biplanar and biconcave morphologies. In TMJ with anterior displacement of the disc with reduction (ADDR), there was a greater correlation with rounded, hemiconvex and biconvex morphologies. Already in the TMJ with displacement without reduction (ADDWR), there was a higher prevalence of folded discs. It can be concluded that morphological changes in the disc are influenced by the type of displacement, and more serious deformations are associated with ADDWR cases.

    Although the etiopathophysiology of internal temporomandibular joint internal disorders (TMJ ID) is still unknown, it has been suggested that head and body posture could be related to its initial onset, development and perpetuation. The purpose of the present study was to observe the relationship between cervical spine X-ray abnormalities and TMJ ID. This investigation evaluated 30 subjects with internal TMJ disorder symptoms (test group) and 20 healthy subjects (control group). Subjects were submitted to clinical and radiographic evaluation. Clinical evaluation comprised anamnesis and stomatognathic system physical examination. Radiographic evaluation comprised analysis of lateral cervical spine X-rays by three physical therapists and tracing on the same images. The test group presented twice as much cervical spine hyperlordosis as the control group (20.7% versus 10.5%), but almost half of rectification prevalence (41.4 versus 79.0%, p = 0.03). After that, the test group was divided into three subgroups according to TMJ dysfunction severity, evaluated by Helkimo's index. These subgroups were not significantly different, but the subgroup with more severe TMD showed a tendency to cervical spine hyperlordosis prevalence. Results showed a tendency for subjects with more severe TMD to exhibit cervical spine hyperlordosis. Nevertheless, studies with a larger number of subjects suffering from severe TMD are encouraged in order to corroborate the present findings.

    Magnetic resonance (MR) imaging of the temporomandibular joint (TMJ) has now been established as a procedure of choice in the evaluation of TMJ disorders. In this study, we evaluated the dynamics of TMJ motion on MR imaging, which resembles arthrography. Sixty-eight TMJs in 38 symptomatic patients and one healthy volunteer were examined using pseudodynamic images with gradient echo sequences using a 0.5 Tesla MR unit and 8 cm circular planar surface coil. For depiction of each compartment of the meniscus, the optimum sequence was 200/15/2 (TR/TE/excitations) with 50 deg or 60 deg flip angle in gradient refocused acquisition in steady-state (GRASS) sequences. Three contiguous slices on sagittal MR images were routinely obtained at 14-18 different phases of the opening cycle and displayed in closed-loop cine fashion. Internal derangement was observed in 57% of 68 joints. The most common type was anterior meniscal displacement without reduction. Sideway and rotational displacements, observed in 10% each, were noted on both sagittal multislice images and axial reference images. As a pseudodynamic MR technique, jaw movement specifically designed to check bite procedure to adjust splints is useful for detecting the exact time of meniscal redisplacement on the second click. After conservative therapy for arthrosis, pseudodynamic MR provided information on changes in the meniscus and condylar relationship. Pseudodynamic MR with multiple phases is suitable for evaluating subtle motion abnormality of the meniscus and for post-therapeutic monitoring. (author)

    Full Text Available Abstract Objective: To evaluate the effect of bite positions characterizing different splint treatments (anterior repositioning and stabilization splints on the disc-condyle relation in patients with TMJ disc displacement with reduction (DDwR, using magnetic resonance imaging (MRI. Material and Methods: 37 patients, with a mean age of 18.8±4.3 years (7 male and 30 females and diagnosed with DDwR based on the RDC/TMD, were recruited. MRI metrical analysis of the spatial changes of the disc/condyle, as well as their relationships, was done in three positions: maximum intercuspation (Position 1, anterior repositioning splint position (Position 2, and stabilization splint position (Position 3. Disc/condyle coordinate measurements and disc condyle angles were determined and compared. Results: In Position 1, the average disc-condyle angle was 53.4° in the 60 joints with DDwR, while it was −13.3° with Position 2 and 30.1° with Position 3. The frequency of successful "disc recapture" with Position 2 was significantly higher (58/60, 96.7% than Position 3 (20/60, 33.3%. In Positions 2 and 3, the condyle moved forward and downward while the disc moved backward. The movements were, however, more remarkable with Position 2. Conclusions: Anterior repositioning of the mandible improves the spatial relationship between the disc and condyle in patients with DDwR. In addition to anterior and inferior movement of the condyle, transitory posterior movement of the disc also occurred.

    2015-12-01

    Full Text Available Objectives: Temporomandibular disc is a mechanically robust fibrocartilage tissue exhibiting highly elastic compressive, shear, and tensile moduli with structurally dense extracellular matrix that supports functional loading of the joint. The aim of this study was to illustrate structural complexities of the superior and inferior disc surfaces, to demonstrate the robust mechanical ability of the disc as a whole may be due to depth-dependent regional/layered variation, and also to provide characterization data imperative for future tissue engineering efforts focused on restoring function to the joint. Material and Methods: Nanoindentation was used to assess tissue zones in conjunction with detailed Transmission Electron Microscopy to define structural attributes that influence the temporomandibular disc function. Results: The disc architecture adjacent to the superior surface was shown to have three distinct regional segments within the interface layer: 1-a surface peripheral layer; 2-subsurface region; and 3-a layer of helical matrix bundles. The inferior surface displayed an interface layer (20 µm that showed limited cell populations with little depth-dependent structural variation, a stiffer elastic modulus and reduced energy dissipation compared to the superior surface. These data indicate that the primary function of the inferior surface is resistance to compression rather than load distribution during joint motion. Conclusions: These are the first works that demonstrate that the superior central surface of the he temporomandibular disc is structured in depth-dependent isometric layers, each of which provides different mechanical function supporting the bulk tissue’s properties. From a clinical perspective these data have potential to define regions susceptible to fatigue that may translate to diagnostic criteria to better define the stages of dysfunction.

    McMahon, Camilla M; Lerner, Matthew D; Britton, Noah

    2013-01-01

    In this paper, we synthesize the current literature on group-based social skills interventions (GSSIs) for adolescents (ages 10–20 years) with higher-functioning autism spectrum disorder and identify key concepts that should be addressed in future research on GSSIs. We consider the research participants, the intervention, the assessment of the intervention, and the research methodology and results to be integral and interconnected components of the GSSI literature, and we review each of these components respectively. Participant characteristics (eg, age, IQ, sex) and intervention characteristics (eg, targeted social skills, teaching strategies, duration and intensity) vary considerably across GSSIs; future research should evaluate whether participant and intervention characteristics mediate/moderate intervention efficacy. Multiple assessments (eg, parent-report, child-report, social cognitive assessments) are used to evaluate the efficacy of GSSIs; future research should be aware of the limitations of current measurement approaches and employ more accurate, sensitive, and comprehensive measurement approaches. Results of GSSIs are largely inconclusive, with few consistent findings across studies (eg, high parent and child satisfaction with the intervention); future research should employ more rigorous methodological standards for evaluating efficacy. A better understanding of these components in the current GSSI literature and a more sophisticated and rigorous analysis of these components in future research will lend clarity to key questions regarding the efficacy of GSSIs for individuals with autism spectrum disorder.

    Objective: To identify the frequency of signs and symptoms of temporomandibular disorder (TMD) and its seve-rity in individuals with headache. Study Design: 60 adults divided into three groups of 20 individuals: chronic daily headache (CDH), episodic headache (EH) and a control group without headache (WH). Headache diagnosis was performed according to the criteria of International Headache Society and the signs and symptoms of TMD were achieved by using a clinical exam and an anamnestic questionnaire. The severity of TMD was defined by the temporomandibular index (TMI). Results: The TMD signs and symptoms were always more frequent in individuals with headache, especially report of pain in TMJ area (CDH, n=16; EH, n=12; WH, n=6), pain to palpation on masseter (CDH, n=19; EH, n=16; WH, n=11) which are significantly more frequent in episodic and chronic daily headache. The mean values of temporomandibular and articular index (CDH patients) and muscular index (CDH and EH patients) were statistically higher than in patients of the control group, notably the articular (CDH=0.38; EH=0.25;WH=0.19) and muscular (CDH=0.46; EH=0.51; WH=0.26) indices. Conclusions: These findings allow us to speculate that masticatory and TMJ pain are more common in headache subjects. Besides, it seems that the TMD is more severe in headache patients. Key words:Temporomandibular dysfunction, headache disorders. PMID:22926473

    The temporomandibular joint(TMJ) is really a complex of two synovial space separated by fibrocartilaginous disc. Single inferior joint space arthrography is commonly performed for evaluation of TMJ disorders, which is known to be superior in demonstrating joint dynamics. But it reveals only the inferior surface of the disc. Therefore, dual space arthrography is superior to demonstrate the soft tissue anatomic feature of the joint such as disc position and shape. Authors performed 83 TMJ arthrograms in TMJ problems. Initially, the inferior joint space was done and then the superior space was sequentially contrasted. The follow results were noted: 1. In all cases, dual space arthrography revealed accurate disc shape and positions. 2. Concordant findings between the two techniques: 68 cases (82%). Discordance between the two techniques: 15 cases (18%) 3. Possible causes of discordance between inferior and dual space arthrography. a) Normal varians of anterior recess: 3 cases b) Posterior disc displacement: 4 cases c) Influence of the patient's head position change :4 cases d) False perforation: 2 cases e) Reduction change: 2 cases 4. In 5 cases with anterior displacement, dual space arthrography gave additional findings such as adhesion within the superior space, which could not be evaluated by single inferior space.

    To assess the prevalence of signs and symptoms related to TMJ disorders in a group of young people with intelectual disability (ID) and a matched group of healthy adolescents. A group of 105 young Special Olympics (SO) athletes (ID group) aged from 14 to 25 years and a control group were examined for the presence or absence of signs and symptoms of TMD through interview and clinical examination. A total of 64 young people with ID (61%) had at least one sign of TMD compared to 41 (39%) of the individuals screened that was free of any TMD symptoms. A significantly higher prevalence of TMJ sounds (palpation and stethoscope), TMJ tenderness, maximum vertical opening, headaches were observed among SO athletes compared to the healthy control group (pdisabled patients and a possible cause of pain that should be examined more in detail. We suggest that oral screening in people with a mental disability should be modified by including basic TMJ examination parameters in order to allow better understanding of the pathological aspects so as to address effective preventive and therapeutic measures.

    Temporomandibular dysfunction involves osteoarthritis of the TMJ, including degeneration and morphologic changes of the mandibular condyle. The purpose of this study was to determine the accuracy of novel 3D-UTE MRI versus micro-CT (μCT) for quantitative evaluation of mandibular condyle morphology. Nine TMJ condyle specimens were harvested from cadavers (2 M, 3 F; age 85 ± 10 years, mean ± SD). 3D-UTE MRI (TR = 50 ms, TE = 0.05 ms, 104-μm isotropic-voxel) was performed using a 3-T MR scanner and μCT (18-μm isotropic-voxel) was also performed. MR datasets were spatially registered with a μCT dataset. Two observers segmented bony contours of the condyles. Fibrocartilage was segmented on the MR dataset. Using a custom program, bone and fibrocartilage surface coordinates, Gaussian curvature, volume of segmented regions, and fibrocartilage thickness were determined for quantitative evaluation of joint morphology. Agreement between techniques (MRI vs. μCT) and observers (MRI vs. MRI) for Gaussian curvature, mean curvature, and segmented volume of the bone were determined using intraclass correlation coefficient (ICC) analysis. Between MRI and μCT, the average deviation of surface coordinates was 0.19 ± 0.15 mm, slightly higher than the spatial resolution of MRI. Average deviation of the Gaussian curvature and volume of segmented regions, from MRI to μCT, was 5.7 ± 6.5 % and 6.6 ± 6.2 %, respectively. ICC coefficients (MRI vs. μCT) for Gaussian curvature, mean curvature, and segmented volumes were 0.892, 0.893, and 0.972, respectively. Between observers (MRI vs. MRI), the ICC coefficients were 0.998, 0.999, and 0.997, respectively. Fibrocartilage thickness was 0.55 ± 0.11 mm, as previously described in the literature for grossly normal TMJ samples. 3D-UTE MR quantitative evaluation of TMJ condyle morphology ex-vivo, including surface, curvature, and segmented volume, shows high correlation against μCT and between observers. In addition, UTE MRI allows

    Human societies demand of its composing members the development of a wide array of social tools and strategies. A notable example is human outstanding ability to cooperate with others, in all its complex forms, depicting the reality of a highly demanding social framework in which humans need to be integrated as to attain physical and mental benefits. Considering the importance of social engagement, it's not entirely unexpected that most psychiatric disorders involve some disruption of normal social behaviour, ranging from an abnormal absence to a significant increase of social functioning. It is however surprising that knowledge on these social anxiety disorders still remains so limited. Here we review the literature focusing on the social and cooperative toolbox of 3 fish model species (cleaner fishes, guppies and zebrafish) which are amenable systems to test for social disorders. We build on current knowledge based on ethological information, arising from studies on cooperative behaviour in cleanerfishes and guppies, while profiting from the advantages of the intense use of zebrafish, to create novel paradigms aiming at the major socio-cognitive modules/dimensions in fish species. This focus may enable the discovery of putative conserved endpoints which are relevant for research into social disorders. We suggest that cross-species, cross-domain, functional and genetic approaches could provide a wider array of information on the neurobiological bases of social and cooperative behaviour, crucial to understanding the neural bases of social disorders and key to finding novel avenues towards treatment.

    A study was conducted to evaluate the efficacy of pumping manipulation treatment for closed lock of the temporomandibular joint (TMJ) disorder using limited cone beam X-ray CT for dental use. The subjects were 20 patients with TMJ closed lock. Arthrography and pumping manipulation treatment were performed, and the correlation between maximal mouth opening and arthrographic findings was examined. Arthrography showed 16 cases of anterior disk displacement, and 4 cases of sideways displacement. Disk configuration showed 15 abnormal cases and 3 cases of disk perforation. Before treatment, mouth opening distance was 24.2 mm and 1 week after treatment it was 34.4 mm. After 3 months this had improved significantly to 41.0 mm. Comparison of mouth opening distance with arthrographic findings showed that disk perforation was significantly different after 3 months. These results suggest that pumping manipulation treatment might be useful in patients with TMJ closed lock without internal derangement or disk perforation. (author)

    To determine the frequency and degree of orofacial myofunctional disorder (OMD) in a sample of patients with temporomandibular disorder (TMD), the dental records of 240 patients with a diagnosis of TMD were reviewed. Mean patient age and mean TMD duration, gender frequency, complaints, and signs and symptoms were calculated. The results showed that the sample studied was quite characteristic of a TMD group. The presence of the following signs/symptoms was significant: muscular pain, TMJ pain, joint noise, at least one otologic symptom, headache, and neck and shoulder pain. Most subjects presented some degree of OMD, with grade high prevailing over grade low. The importance of evaluating the stomatognathic structures and functions during the clinical examination of patients with TMD is emphasized.

    Temporomandibular disorders (TMD) are a group of clinical problems affecting temporomandibular joint (TMJ), myofascial muscles and other related structures. Splint therapy is the most commonly used approach to treatment of TMD, but its effectiveness is remains unclear. We therefore conducted a meta-analysis to evaluate the effectiveness of splint therapy for TMD in adults. The electronic databases PubMed, EMBASE, Cochrane Library, and ClinicalTrials.gov were searched for reports published up ...

    Pain related to temporomandibular disorders (TMD) is a common problem in modern societies. The aim of the article is to present the concepts of TMD pain clinical management. A survey was performed using the PubMed, SCOPUS and CINAHL databases for documents published between 1994 and 2014. The following search keywords were selected using MeSH terms of the National Library of Medicine in combination: TMD pain, TMD, TMJ, TMJ disorders, occlusal splint, TMD physiotherapy, TMJ rheumatoid disorders and TMJ surgery. Original articles and review papers which presented the clinical relevance and practical validity regarding the possibility of application in TMD management have been included. Authors have excluded articles without outstanding practical aspect and evidence-based background. A first selection was carried out by reviewing titles and abstracts of all articles found according to the criteria. After that the full texts of potentially suitable articles were assessed. In line with these criteria, among 11467 results the writers have included 66 papers. The most commonly reported conservative treatments are massage therapy and individually fabricated occlusal splints. In addition to massage, other popular methods include manual therapy and taping, warming/cooling of aching joints, and light and laser therapy. Drugs are also commonly used. In the most severe cases of the temporomandibular joint degeneration, surgical restoration of the joint is sometimes applied. The authors concluded that conservative treatment including counselling, exercises, occlusal splint therapy, massage, manual therapy and others should be considered as a first choice therapy for TMD pain because of their low risk of side effects. In the case of severe acute pain or chronic pain resulting from serious disorders, inflammation and/or degeneration pharmacotherapy, minimally invasive and invasive procedures should be considered.

  18. Episodic memory and episodic future thinking impairments in high-functioning autism spectrum disorder: an underlying difficulty with scene construction or self-projection?

    There appears to be a common network of brain regions that underlie the ability to recall past personal experiences (episodic memory) and the ability to imagine possible future personal experiences (episodic future thinking). At the cognitive level, these abilities are thought to rely on "scene construction" (the ability to bind together multimodal elements of a scene in mind--dependent on hippocampal functioning) and temporal "self-projection" (the ability to mentally project oneself through time--dependent on prefrontal cortex functioning). Although autism spectrum disorder (ASD) is characterized by diminished episodic memory, it is unclear whether episodic future thinking is correspondingly impaired. Moreover, the underlying basis of such impairments (difficulties with scene construction, self-projection, or both) is yet to be established. The current study therefore aimed to elucidate these issues. Twenty-seven intellectually high-functioning adults with ASD and 29 age- and IQ-matched neurotypical comparison adults were asked to describe (a) imagined atemporal, non-self-relevant fictitious scenes (assessing scene construction), (b) imagined plausible self-relevant future episodes (assessing episodic future thinking), and (c) recalled personally experienced past episodes (assessing episodic memory). Tests of narrative ability and theory of mind were also completed. Performances of participants with ASD were significantly and equally diminished in each condition and, crucially, this diminution was independent of general narrative ability. Given that participants with ASD were impaired in the fictitious scene condition, which does not involve self-projection, we suggest the underlying difficulty with episodic memory/future thinking is one of scene construction.

  19. Management of temporomandibular joint disorders caused by complication of teeth extraction

    Full Text Available Complicated tooth extractions may lead to various post-extraction complications, including Temporomandibular Joint Disorders (TMD. Despite of the rare incidence, a delayed treatment of the TMD will cause more problems in the future as well as increased morbidity rate. The purpose of the current study was to elaborate the symptoms as well as the management of TMD as a post tooth extraction complication. The types of TMD as a post tooth extraction complication includes dislocated condyle, osteoarthritis, fracture condyle and disc displacement. These type of complications may resulted from an extensive opening of the mouth as well as an over pressure on the mandible during tooth extraction. In relation to this, some of the TMD symptoms that might cause a certain level of interference for patients may include pain, limited mouth opening and joint sounds, with pain and limited mouth opening as the initial symptoms. The first measure of the pain management would be warm light compress around the TMJ followed by a soft diet for food intake. A definitive treatment should then be based on the diagnosis of the TMD. It is concluded that TMD may occur as a complication of a tooth extraction that initiated by pain and limited mouth opening. Immediate treatment would be pain relieve and load reduction of the Temporomandibular Joint by employing soft diet and mandibular movement restriction.

    We present an update of recent literature (since 2007) exploring the factor structure of posttraumatic stress disorder (PTSD) symptom measures. Research supporting a four-factor emotional numbing model and a four-factor dysphoria model is presented, with these models fitting better than all other models examined. Variables accounting for factor structure differences are reviewed, including PTSD query instructions, type of PTSD measure, extent of trauma exposure, ethnicity, and timing of administration. Methodological and statistical limitations with recent studies are presented. Finally, a research agenda and recommendations are offered to push this research area forward, including suggestions to validate PTSD’s factors against external measures of psychopathology, test moderators of factor structure, and examine heterogeneity of symptom presentations based on factor structure examination.

  1. Paradigm shifts and the development of the diagnostic and statistical manual of mental disorders: past experiences and future aspirations.

    Work is currently under way on the Diagnostic and Statistical Manual of Mental Disorders (DSM), Fifth Edition, due to be published by the American Psychiatric Association in 2013. Dissatisfaction with the current categorical descriptive approach has led to aspirations for a paradigm shift for DSM-5. A historical review of past revisions of the DSM was performed. Efforts undertaken before the start of the DSM-5 development process to conduct a state-of-the science review and set a research agenda were examined to determine if results supported a paradigm shift for DSM-5. Proposals to supplement DSM-5 categorical diagnosis with dimensional assessments are reviewed and critiqued. DSM revisions have alternated between paradigm shifts (the first edition of the DSM in 1952 and DSM-III in 1980) and incremental improvements (DSM-II in 1968, DSM-III-R in 1987, and DSM-IV in 1994). The results of the review of the DSM-5 research planning initiatives suggest that despite the scientific advances that have occurred since the descriptive approach was first introduced in 1980, the field lacks a sufficiently deep understanding of mental disorders to justify abandoning the descriptive approach in favour of a more etiologically based alternative. Proposals to add severity and cross-cutting dimensions throughout DSM-5 are neither paradigm shifting, given that simpler versions of such dimensions are already a component of DSM-IV, nor likely to be used by busy clinicians without evidence that they improve clinical outcomes. Despite initial aspirations that DSM would undergo a paradigm shift with this revision, DSM-5 will continue to adopt a descriptive categorical approach, albeit with a greatly expanded dimensional component.

    Increasing predictability of animal models of posttraumatic stress disorder (PTSD) has required active collaboration between clinical and preclinical scientists. Modeling PTSD is challenging, as it is a heterogeneous disorder with ≥20 symptoms. Clinical research increasingly utilizes objective biological measures (e.g., imaging, peripheral biomarkers) or nonverbal behaviors and/or physiological responses to complement verbally reported symptoms. This shift toward more-objectively measurable phenotypes enables refinement of current animal models of PTSD, and it supports the incorporation of homologous measures across species. We reviewed >600 articles to examine the ability of current rodent models to probe biological phenotypes of PTSD (e.g., sleep disturbances, hippocampal and fear-circuit dysfunction, inflammation, glucocorticoid receptor hypersensitivity) in addition to behavioral phenotypes. Most models reliably produced enduring generalized anxiety-like or depression-like behaviors, as well as hyperactive fear circuits, glucocorticoid receptor hypersensitivity, and response to long-term selective serotonin reuptake inhibitors. Although a few paradigms probed fear conditioning/extinction or utilized peripheral immune, sleep, and noninvasive imaging measures, we argue that these should be incorporated more to enhance translation. Data on female subjects, on subjects at different ages across the life span, or on temporal trajectories of phenotypes after stress that can inform model validity and treatment study design are needed. Overall, preclinical (and clinical) PTSD researchers are increasingly incorporating homologous biological measures to assess markers of risk, response, and treatment outcome. This shift is exciting, as we and many others hope it not only will support translation of drug efficacy from animal models to clinical trials but also will potentially improve predictability of stage II for stage III clinical trials.

    This study explored spatial navigation alongside several other cognitive abilities that are thought to share common underlying neurocognitive mechanisms (e.g., the capacity for self-projection, scene construction, or mental simulation), and which we hypothesized may be impaired in autism spectrum disorder (ASD). Twenty intellectually high-functioning children with ASD (with a mean age of ~8 years) were compared to 20 sex, age, IQ, and language ability matched typically developing children on a series of tasks to assess spatial navigation, episodic memory, episodic future thinking (also known as episodic foresight or prospection), theory of mind (ToM), relational memory, and central coherence. This is the first study to explore these abilities concurrently within the same sample. Spatial navigation was assessed using the "memory island" task, which involves finding objects within a realistic, computer simulated, three-dimensional environment. Episodic memory and episodic future thinking were assessed using a past and future event description task. ToM was assessed using the "animations" task, in which children were asked to describe the interactions between two animated triangles. Relational memory was assessed using a recognition task involving memory for items (line drawings), patterned backgrounds, or combinations of items and backgrounds. Central coherence was assessed by exploring differences in performance across segmented and unsegmented versions of block design. Children with ASD were found to show impairments in spatial navigation, episodic memory, episodic future thinking, and central coherence, but not ToM or relational memory. Among children with ASD, spatial navigation was found to be significantly negatively related to the number of repetitive behaviors. In other words, children who showed more repetitive behaviors showed poorer spatial navigation. The theoretical and practical implications of the results are discussed.

    People with schizophrenia or bipolar disorder (BD) exhibit very high levels of obesity. Little is known about the potential benefits/risks of obesity surgery. We conducted a narrative review to summarize the available knowledge on bariatric surgery in people with schizophrenia or BD. A systematic search was conducted of major electronic databases from inception to October 2016 for studies investigating bariatric surgery among people with schizophrenia or BD. Data were presented in a narrative synthesis and future research strategies proposed. The electronic database searches identified 44 records. Eight studies (BD, n = 265; schizophrenia: n = 14) were included with a mean study length of 15.7 months (12-24). Seven found that bariatric surgery resulted in weight loss in those with psychiatric disorders with an excess weight loss ranging -31 to -70%. Six studies found that weight loss from bariatric surgery was similar in people with schizophrenia or BD versus controls. However, most of the studies limited their outcomes to only weight loss and did not measure whether obesity surgery affected the status and treatment of psychiatric symptoms. Although few adverse events were reported among patients with BD, data from two studies demonstrated no significant deterioration of psychiatric symptoms post-surgery in people with schizophrenia. Growing evidence suggests that bariatric surgery may improve short-term weight status among people with BD. However, given the paucity of studies for schizophrenia, and the lack of information on medium-to long-term results, future large-scale high-quality studies are required.

    Full Text Available Background: Major depressive disorder (MDD is associated with increased heart rate and reductions in its variability (HRV – markers of future morbidity and mortality – yet prior studies have reported contradictory effects. We hypothesised that increases in heart rate and reductions in HRV would be more robust in melancholia relative to controls, than in patients with non-melancholia. Methods: A total of 72 patients with a primary diagnosis of MDD (age M: 36.26, SE: 1.34; 42 females and 94 controls (age M: 35.69, SE: 1.16; 52 females were included in this study. Heart rate and measures of its variability (HRV were calculated from two 2-minute electrocardiogram recordings during resting state. Propensity score matching controlled imbalance on potential confounds between patients with melancholia (n=40 and non-melancholia (n=32 including age, gender, disorder severity and comorbid anxiety disorders. Results: MDD patients with melancholia displayed significantly increased heart rate and lower resting-state HRV (including the square root of the mean squared differences between successive N–N intervals, the absolute power of high frequency and standard deviation of the Poincaré plot perpendicular to the line of identity measures of HRV relative to controls, findings associated with a moderate effect size (Cohens d’s = 0.56-0.58. Patients with melancholia also displayed an increased heart rate relative to those with non-melancholia (Cohen’s d = 0.20.Conclusion: MDD patients with melancholia – but not non-melancholia – display robust increases in heart rate and decreases in HRV. These findings may underpin a variety of behavioural impairments in patients with melancholia including somatic symptoms, cognitive impairment, reduced responsiveness to the environment, and over the longer-term, morbidity and mortality.

    Temporomandibular disorders (TMD) consist of a group of pathologies that affect the masticatory muscles, temporomandibular joints (TMJ), and/or related structures. String instrumentalists, like many orchestra musicians, can spend hours with head postures that may influence the biomechanical behavior of the TMJ and the muscles of the craniocervicomandibular complex (CCMC). The adoption of abnormal postures acquired during performance by musicians can lead to muscular hyperactivity of the head and cervical muscles, with the possible appearance of TMD. Medical infrared thermography is a non-invasive procedure that can monitor the changes in the superficial tissue related to blood circulation and may serve as a complement to the clinical examination. The objective of this study was to use infrared thermography to evaluate, in one subject, the cutaneous thermal changes adjacent to the CCMC that occur before, during, and after playing a string instrument.

    The aims of this study are to evaluate the prevalence of disorders of the lumbar region and the temporo-mandibular district co-morbidity in drivers and workers of the State Police employed for different office activities. The study population included 103 drivers as cases and 100 police officers as controls. The study was carried out through questionnaire and clinical evaluation of the spine and temporo-mandibular region. At clinical examination, the drivers were found to have a higher prevalence (p temporo-mandibular joint (TMJ), when compared with the controls. The results also showed a higher prevalence (p < 0.05) of co-morbidity in the two districts among the drivers, when compared with the controls. These results confirm that morbidity related to back and TMJ and increase in co-morbidity between the two districts are higher in professional drivers.

    The purpose of this study was to elevate comparison of static MRI and pseudo-dynamic (cine) MRI in temporomandibular joint (TMJ) disorder patients. In this investigation, 33 patients with TMJ disorders were examined using both conventional static MRI and pseudo-dynamic MRI. Multiple spoiled gradient recalled acquisition in the steady state (SPGR) images were obtained when mouth opened and closed. Proton density weighted images were obtained at the closed and open mouth position in static MRI. Two oral and maxillofacial radiologists evaluated location of the articular disk, movement of condyle and bony change respectively and the posterior boundary of articular disk was obtained. No statistically significant difference was found in the observation of articular disk position, mandibular condylar movement and posterior boundary of articular disk using static MRI and pseudo-dynamic MRI (P>0.05). Statistically significant difference was noted in bony changes of condyle using static MRI and pseudo-dynamic MRI (P<0.05). This study showed that pseudo-dynamic MRI didn't make a difference in diagnosing internal derangement of TMJ in comparison with static MRI. But it was considered as an additional method to be supplemented in observing bony change.

    Immunotherapy targeting α-synuclein has evolved as a potential therapeutic strategy for neurodegenerative diseases, such as Parkinson's disease, and initial studies on cellular and animal models have shown promising results. α-synuclein vaccination of transgenic mice reduced the number of brain inclusions, whereas passive immunization studies demonstrated that antibodies against the C-terminus of α-synuclein can pass the blood-brain barrier and affect the pathology. In addition, preliminary evidence suggests that transgenic mice treated with an antibody directed against α-synuclein oligomers/protofibrils resulted in reduced levels of such species in the CNS. The underlying mechanisms of immunotherapy are not yet fully understood, but may include antibody-mediated clearance of pre-existing aggregates, prevention of protein propagation between cells and microglia-dependent protein clearance. Thus, immunotherapy targeting α-synuclein holds promise, but needs to be further developed as a future disease-modifying treatment in Parkinson's disease and other α-synucleinopathies.

    Rapid eye movement (REM) sleep behavior disorder (RBD) is a parasomnia manifested by vivid, often frightening dreams associated with simple or complex motor behavior during REM sleep. Patients appear to “act out their dreams,” in which the exhibited behaviors mirror the content of the dreams, and the dream content often involves a chasing or attacking theme. The polysomnographic features of RBD include increased electromyographic tone +/- dream enactment behavior during REM sleep. Management with counseling and pharmacologic measures is usually straight-forward and effective. In this review, the terminology, clinical and polysomnographic features, demographic and epidemiologic features, diagnostic criteria, differential diagnosis, and management strategies are discussed. Recent data on the suspected pathophysiologic mechanisms of RBD are also reviewed. The literature and our institutional experience on RBD are next discussed, with an emphasis on the RBD-neurodegenerative disease association and particularly the RBD-synucleinopathy association. Several issues relating to evolving concepts, controversies, and future directions are then reviewed, with an emphasis on idiopathic RBD representing an early feature of a neurodegenerative disease and particularly an evolving synucleinopathy. Planning for future therapies that impact patients with idiopathic RBD is reviewed in detail. PMID:20146689

    Aim: To evaluate the influence of MRI of the temporomandibular joint on the therapeutic strategy in patients with craniomandibular disorders (internal derangement) and, furthermore, to analyze interobserver agreement for defined MRI criteria. Materials and Methods: Fifty-one unilateral and bilateral MRI examinations of 32 patients were enrolled. Therapeutic strategies before and after performance of the MRI were compared. Retrospectively, two radiologists independently analyzed the MR images for position of the disk, position of the condyle, signal intensity of the disk and bilaminar zone, osseous changes and several additional findings, using a check list. Agreement was tested by kappa statistics. Results: In 56% of the cases, changes of the therapeutic regimen were registered after MRI. Statistically significant agreement of the two observers was found for anterior position of the disk (kappa=0.44), transverse position of the disk (kappa=0.46) and position of the condyle (kappa=0.45). No significant agreement was found for signal intensity of the disk (kappa=0.14) or bilaminar zone (kappa=0.24), osseous changes (kappa=0.13) and the additional findings (kappa=0.29). Discussion: MRI has a measurable impact on the therapeutic approach to the internal derangement of the TMJ. The position of the disk and condyle can be reproducibly judged, while the signal intensity of the disk and bilaminar zone and the osseous changes are subject to wide observer variations. (orig.)

This study aimed to investigate the prevalence of TMD signs in subjects with and without BD. Material and Methods: The case group included 242 adult patients (103 men and 139 women with BD and and the control group included 187 subjects without BD (89 men and 98 women. The case and control groups were compared for the presence of bruxism and the signs of TMD including muscle and temporomandibular joint (TMJ tenderness to palpation, limitation of maximum mouth opening, and TMJ sounds. Results: The frequency of at least one sign of TMD was significantly higher in patients with BD (191 ⁄242, 78.9% than the control group (95 ⁄187, 50.8% (p<0.001. Statistically significant differences were found between the case and control groups in terms of joint pain on palpation (p<0.05, masseter muscle pain on palpation (p<0.01, joint clicks (p<0.001 and limited mouth opening (p<0.001. Bruxism was significantly higher in patients with BD (49.6% than the control group (19.8% (p<0.001. Conclusions: Patients with BD appear to be more prone to having TMD signs and bruxism compared to the control group, but this comorbidity should be better understood by further studies.

    Full Text Available A study was conducted to assess the prevalence of psychosocial disorders in patients with TMD, and to establish correlation between these, and symptoms and physical signs of TMD. Thirty patients were included in the study. TMD history and TMJ examination findings were recorded. Subsequently psychosocial assessment was carried out. Eighteen patients were in psychiatric morbid (PM group and 12 were in psychiatric nonmorbid (PNM group. Symptoms and signs of TMD were compared between PM and PNM group. Strong association was evident between presence of psychiatric morbidity and certain parameters viz. pain duration, VAS, bruxism, mouth opening.

  18. The role of temporomandibular joint dysfunction and occlusal disorders in the pathophysiology of somatogenic cochlear and vestibular syndrome

    Full Text Available Rationale: Temporomandibular joint (TMJ dysfunction and occlusion abnormalities can cause cochlear and vestibular disorders. This issue is at the crossroads of several disciplines: otoneurology, physiotherapy, dentistry, medical rehabilitation and posturology, which often makes it difficult to timely diagnose them and delays the onset of treatment. Aim: To assess the role of abnormal dental occlusion and TMJ disorders in the pathophysiology and clinical manifestation of cochleovestibular syndrome. Materials and methods: We examined 300 subjects with clinical signs of cochleovestibular syndrome, asymmetry of occlusion and/or TMJ dysfunction (the main group, 55 patients with signs of TMJ structural and functional disorders and occlusal disorders without a cochleovestibular syndrome (the reference group, and 35 healthy volunteers (the control group. All patients were examined by a neurologist, an ENT specialist, a dentist and a physiotherapist. A series of additional investigations of the brachiocephalic vessels, cervical spine, TMJ, auditory and vestibular function, premature tooth contacts were performed. Results: The main group patients had high values of TMJ dysfunction in the Hamburg test (5.85 vs 2.2 in the reference group and higher proportions of patients with moderate and severe TMJ dysfunction (n = 243, 81% and n = 13, 23.7%, respectively. The functional muscle test parameters and the results of manual muscle testing in the main group patients were significantly different from those in the control group (р < 0.05, whereas most values obtained in the reference group did not differ significantly (р > 0.05. Patients with cochleoves-tibular syndrome had 2 to 3-fold higher rates of vertebrogenic dysfunctions than those from the reference group. The video nystamography technique detected the positional cervical nystagmus in 100% (n = 300 of patients from the main group, whereas there were no nystagmus in those from the reference group

    To identify the frequency of signs and symptoms of temporomandibular disorder (TMD) and its severity in individuals with headache. 60 adults divided into three groups of 20 individuals: chronic daily headache (CDH), episodic headache (EH) and a control group without headache (WH). Headache diagnosis was performed according to the criteria of International Headache Society and the signs and symptoms of TMD were achieved by using a clinical exam and an anamnestic questionnaire. The severity of TMD was defined by the temporomandibular index (TMI). The TMD signs and symptoms were always more frequent in individuals with headache, especially report of pain in TMJ area (CDH, n=16; EH, n=12; WH, n=6), pain to palpation on masseter (CDH, n=19; EH, n=16; WH, n=11) which are significantly more frequent in episodic and chronic daily headache. The mean values of temporomandibular and articular index (CDH patients) and muscular index (CDH and EH patients) were statistically higher than in patients of the control group, notably the articular (CDH=0.38; EH=0.25;WH=0.19) and muscular (CDH=0.46; EH=0.51; WH=0.26) indices. These findings allow us to speculate that masticatory and TMJ pain are more common in headache subjects. Besides, it seems that the TMD is more severe in headache patients.

    In treating patients with temporomandibular joint (TMJ) dysfunction it was noticed that tinnitus and vertigo were common in such patients and there was also muscular tension in jaw and neck. During treatment of these patients it was also noted that injection of lidocaine in a jaw muscle (m. pt. lat.) reduced not only their muscular problems but also that the tinnitus was reduced while the local anesthetic was active. Evaluation of 39 patients with disabling tinnitus, and all suffered from tinnitus, revealed that 10 of them had bilateral tinnitus and TMJ disorders revealed that pain in the face, temples or jaw occurred often among these patients. Many of such patients had also symptoms of cervical spine disorders, head, neck and shoulder pain, and limitations in side bending and rotation were also frequent complaints. One-third of these patients could influence tinnitus by jaw movements and 75% could trigger vertigo by head or neck movements. Treatment of jaw and neck disorders in 24 patients with Ménière's disease had a beneficial effect on not only their episodic vertigo but also on their tinnitus and aural fullness. At the 3-year follow-up, intensity of all symptoms were significantly reduced (p<0.001).

    In this executive summary, the authors describe a protocol for assessing patients with temporomandibular disorder (TMD). It is based on the Diagnostic Criteria for Temporomandibular Disorders (DC/TMD) for clinical and research applications. The DC/TMD was developed using published Axis I physical diagnoses for the most common TMDs. Axis I diagnostic criteria were derived from pertinent clinical TMD signs and symptoms. Axis II consists of psychosocial and behavioral questionnaires already in the public domain. A panel of experts vetted and modified the Axis I and Axis II diagnostic protocols. Recommended changes were assessed for diagnostic accuracy by using the Validation Project's data set, which formed the basis for the development of the DC/TMD. Axis I diagnostic criteria for TMD pain-related disorders have acceptable validity and provide definitive diagnoses for pain involving the temporomandibular joint (TMJ) and masticatory muscles. Axis I diagnostic criteria for the most common TMJ intra-articular disorders are appropriate for screening purposes only. A definitive diagnosis for TMJ intra-articular disorders requires computed tomography or magnetic resonance imaging. Axis II questionnaires provide valid assessment of psychosocial and behavioral factors that can affect management of TMD. The DC/TMD provides a questionnaire for the pain history in conjunction with validated clinical examination criteria for diagnosing the most common TMDs. In addition, it provides Axis II questionnaires for assessing psychosocial and behavioral factors that may contribute to the onset and perpetuation of the patient's TMD. The DC/TMD is appropriate for use in clinical and research settings to allow for a comprehensive assessment of patients with TMD. Copyright © 2016 American Dental Association.

    Purpose The purpose of the present study was to perform a pattern analysis in patients with temporomandibular disorder (TMD) resulting from unilateral mastication due to chronic periodontitis. Methods Thirty participants with signs or symptoms of TMD who engaged in unilateral mastication due to periodontitis-related discomfort (test group) were selected. Another 30 subjects exhibiting signs or symptoms of TMD resulting from unilateral mastication not due to chronic periodontitis (control group) were also recruited. An interview-based questionnaire was administered, and an examination of the temporomandibular joint (TMJ) with determination of periodontal status was performed. Results The duration of unilateral mastication was significantly longer in the control group than in the test group. There was a significant negative correlation between the duration of unilateral mastication and the Community Periodontal Index score. Using the Research Diagnostic Criteria for TMD (RDC/TMD) axis I algorithms, all the subjects were assigned to 3 main groups. The test group exhibited significantly a higher diagnostic distribution of group III (arthralgia, osteoarthritis, or osteoarthrosis), and in both the test and control groups, the number of diagnoses was larger for the non-chewing side. The control group showed a significantly higher diagnostic distribution of group I (myofacial pain), and in both the test and control groups, the number of diagnoses was larger for the chewing side. Conclusions The results of the present study indicate that unilateral mastication due to chronic periodontitis could induce not only pain but also structural TMJ changes if adequate treatment is not administered and supported within a short time from the onset of the condition. Therefore, immediate treatment of chronic periodontitis is recommended to prevent not only the primary progress of periodontal disease, but also secondary TMJ-related problems. Furthermore, subjects who have suffered chronic

    To investigate the usefulness of a quantitative parameter (maximum standardised uptake value [SUVmax]) of 18 F-sodium fluoride (NaF) positron-emission tomography (PET)/computed tomography (CT) for the evaluation of temporomandibular joint (TMJ) disorder (TMD). Seventy-six TMD patients (male: female=14:62, age=40.3±17.1 years, bilateral: unilateral=40:36) with 152 TMJs were enrolled. The 18 F-NaF PET/CT parameter (SUVmax) was compared with the presence of TMJ arthralgia (arthralgic=86, non-arthralgic=66) and clinical subtypes based on the Research Diagnostic Criteria for TMD Axis I (TMD osteoarthritis=49, non-TMD osteoarthritis=67, and asymptomatic TMJ=36). Splint therapy was applied to 48 patients for 6 months without considering 18 F-NaF PET/CT findings. Post-splint therapy 18 F-NaF PET/CT was performed in 32 patients and clinical responses to the therapy were classified into improvement (n=33), no change (n=10), or aggravation (n=7) for 50 TMJs excluding asymptomatic TMJs (n=14). SUVmax was significantly greater in arthralgic TMJs than in non-arthralgic TMJs (6.62±3.56 versus 4.32±1.53, pchange in SUVmax was observed in improved (from 6.16±2.68 to 6.09±2.60, p=0.4915) and unchanged (from 6.46±4.19 to 6.77±4.32, p=0.3223) TMJs. 18 F-NaF PET/CT is a useful imaging tool for TMD evaluation because SUVmax showed a fair diagnostic performance for arthralgic TMJ and TMD osteoarthritis, and a correlation with the therapeutic response.

    To evaluate the prevalence of self-reported bruxism and symptoms of temporomandibular disorders (TMD) and to investigate their association in academic and applied science university students in Finland. The data were gathered from 4,403 Finnish students included in the Finnish Student Health Survey 2012. The comprehensive questionnaire included five questions concerning bruxism and TMD symptoms. Bivariate associations between self-reported bruxism and TMD symptoms were evaluated using chi-square tests, and logistic regression model was used with age and gender as factors. Sleep bruxism was reported by 21.0% of women and by 12.5% of men, awake bruxism by 2.0% of women and by 2.8% of men, and both sleep and awake bruxism by 7.2% of women and by 3.2% of men. TMD pain was reported by 25.9% of women and by 11.4% of men and temporomandibular joint (TMJ) pain on jaw movement by 9.6% of women and by 4.2% of men. Report of sleep bruxism increased the risk for all TMD symptoms in both genders. Among women, report of awake bruxism increased the risk for TMD pain and TMJ pain on jaw movement. Reporting stress as a perpetuating factor for TMD pain increased the risk for both sleep and awake bruxism in both genders. The logistic regression analysis (including age and gender) showed that report of sleep bruxism and/or awake bruxism was associated with TMD pain (Odds Ratio [OR] = 5.71; 95% confidence interval [CI] = 4.86-6.70), TMJ pain on jaw movement (OR = 4.49; 95% CI = 3.54-5.69), and TMJ locking (OR = 2.98; 95% CI = 2.17-4.10). Bruxism and TMD symptoms are frequent in Finnish university students. Self-reported bruxism is associated with TMD symptoms, confirming earlier findings.

    The aim of this study was to investigate the prevalence and intensity of masticatory muscle and temporomandibular joint (TMJ) pain in Croatian war veterans with posttraumatic stress disorder (PTSD). The examined group consisted of 100 Croatian war veterans, in whom PTSD had previously been diagnosed. Patients were compared with 92 subjects who had not taken part in the war and in whom PTSD was excluded by psychiatric examination. The clinical examination consisted of palpation of the masticatory muscles, the prominent neck musculature, and TMJ. The examination technique used and the definition of items were previously tested for reliability and validity. 93% of the subjects with PTSD had masticatory muscle tenderness compared to 45.65% of the subjects in the control group (chi2 = 51.46, p < 0.0001). The most frequent painful location in the subjects with PTSD was the left lateral pterygoid site in 88%, and in subjects of the control group the right lateral pterygoid site in 28.26% of cases. The most painful location in the PTSD group was the left lateral pterygoid site in 72%, and in the control group the left posterior digastric in 4.35% of cases. 58% of the subjects with PTSD had TMJ tenderness compared to 3.26% of subjects in the control group (chi2 = 66.23, p < 0.0001). The most frequent painful location of TMJ in both groups was the left posterior capsule; in the PTSD group 38% and in subjects in the control group 2.17% of cases. The most painful location was the left posterior capsule in 28% of subjects with PTSD, while not one subject in the control group reported severe painful sensitivity. The very high frequency and intensity of pain in subjects with PTSD confirms the effect of stress on muscle and joint sensitivity, i.e. perception of pain.

    In Sweden, the Addiction Severity Index (ASI) is the Swedish National Board of Health and Welfare's recommended substance use disorder assessment tool and used routinely for patient intakes. Our study of 213 individuals assessed for substance use disorder with the ASI used nine years of the National Patient Register and examined whether clinical social workers' assessments of addiction severity at baseline were associated with later hospitalizations for mental health disorder (MHD). ASI composite scores and interviewer severity rating were used to measure clients' problems in seven areas (mental health, family and social relationships, employment, alcohol, drug use, health, and legal) at baseline. A stepwise regression method was used to assess the relative importance of ASI composite scores, MHD hospitalization two years prior to baseline, age, and gender for MHD hospitalization seven years post-baseline. Almost two-thirds of the individuals (63%) were hospitalized at least once for MHD in the seven years post-baseline. At the multivariable level, MHD hospitalization prior to baseline was the strongest predictor of future MHD hospitalization, followed by ASI composite scores for drug use, employment, mental health and, last, male gender. A key finding is that higher ASI composite scores for drug use and mental health are predictors of future need for MHD treatment. Future studies will replicate this effort with a national population of individuals with substance use disorder.

    Major depressive disorder (MDD) has been proposed to represent a "disease of premature aging", which is associated with certain biomarkers of cellular ageing and numerous other age-related diseases. Over the last decade, telomere length (TL) arose as a surrogate for cellular aging. Recent data suggests that TL might be reduced in patients with MDD, however, results are still inconclusive. This might be explained by the lack of assessment of potential biochemical mediators that are directly associated with telomere shortening and frequently observed in patients with MDD. A narrative review was performed. The PubMed database was searched for relevant studies. We identified four major mediators, which are recurrently reported in patients with MDD and are associated with reduced TL: inflammation/oxidative stress, dysregulation of the hypothalamic-pituitary-adrenal axis, metabolic dysbalance including insulin resistance, and decreased brain-derived neurotrophic factor. These mediators are also mutually associated and were not systematically assessed in current studies investigating TL and MDD, which might explain inconclusive findings across current literature. Finally, we discuss possible ways to assess those mediators and potential implications of such approaches for future research. The majority of identified studies had cross-sectional designs and used heterogeneous methods to assess TL and associated relevant biochemical mediators. A better understanding of the complex interactions between biochemical mediators, somatic comorbidities and shortened telomeres in patients with MDD might further specify the pathophysiology-based conceptualization and, based on that, personalized treatment of MDD.

    This research aimed at assessing the relation between the horizontal condylar angle (HCA) and the internal derangement (ID) of the temporomandibular joint (TMJ), as a result of interference by the T MJ disk, in individuals undergoing magnetic resonance (MR) scans. The sample included a total of 144 TMJs (sagittal and coronal views) of 72 subjects, 15 of whom were male and 57 female, with ages ranging from 15 to 70. The scans were made in a Signa system model at a magnetic field magnitude of 1.5 T. Sixty-eight TMJs were found to be normal, while 46 showed anterior displacement with reduction. Of these, 41 had some kind of adaptive change in the condyle, while 5 showed degenerative changes. Anterior displacement without reduction was found in 29 joints, 12 of which showed adaptive changes in the condyle, while 17 showed degenerative changes. Only one posterior displacement of the articular disk was recorded. For the TMJs in which disk displacement was found, such values achieved 24.69 deg on the right side, and 22.94 deg on the left side. Hence, it was possible for us to conclude that the HCA tends to increase in those TMJs where ID is present. For contralateral TMJs, a strong association was observed between HCA values (57.8%), state of normality (69.7%), and ID (66.7%). To corroborate such findings, a correlation between contralateral HCA values (63.31%) and the diagnosis for contralateral TMJs (68.05%) was determined. Thus, we could infer that there is a tendency between contralateral TMJs to share characteristics and conditions. (author)

    To investigate the corrosion behaviour of commonly used TMJ implants alloys (CoCrMo and Ti6Al4V) under simulated physiological conditions. Corrosion behaviour was evaluated using standard electrochemical corrosion techniques and galvanic corrosion techniques as per ASTM standards. Standard electrochemical tests (E(corr), I(corr), R(p) and C(f)) were conducted in bovine calf serum (BCS), as a function of alloys type and different pHs. Galvanic corrosion tests were conducted in BCS at a pH of 7.6. Alloy surfaces were characterized using white-light interferometry (WLI) and scanning electron microscopy (SEM). The potentiodynamic test results exhibited the enhanced passive layer growth and a better corrosion resistance of Ti6Al4V compared to CoCrMo. Electrochemical impedance spectroscopy measurements demonstrated the influence of protein as a function of pH on corrosion mechanisms/kinetics. Galvanic coupling was not a major contributor to corrosion. SEM and WLI images demonstrated a significantly higher in surface roughness in CoCrMo after corrosion. The results of this study suggest that Ti6Al4V shows superior corrosion behaviour to CoCrMo due to its strong passive layer, simulated joint fluid components can affect the electrochemical nature of the metal/electrolyte interface as a function of pH, and the galvanic effect of coupling CoCrMo and Ti6Al4V in a single joint is weak.

    Alterations in volitional control have been found for various mental disorders. However, it remains unclear to which degree such alterations vary by type of psychopathology and constitute preceding vulnerabilities or correlates of mental disorders. DSM-IV mental disorders were assessed among adolescents and young adults from the community at baseline (age 14-24) and in up to 3 follow-up assessments over 10 years (n = 2515) using a standardized diagnostic interview (DIA-X/M-CIDI). Self-reported volitional control was assessed at second follow-up (T2) when subjects were aged 17-28 using the German version of the Short Form of the Volitional Components Inventory. Linear regressions adjusted for sex, age and lifetime disorders revealed that anxiety and affective disorders were associated with widespread alterations in self-reported volitional control (lower self regulation, higher self inhibition and volitional inhibition), while substance use disorders were specifically associated with higher volitional inhibition. Logistic regressions adjusted for sex, age and prior lifetime psychopathology revealed that lower self-reported volitional control at T2 predicted incident panic, social phobia and substance use at T3 (follow-up interval M = 4.8 years). Findings point toward at least partly disorder-specific alterations in volitional control in mental disorders, which might be antecedent vulnerability factors and thus useful to guide early recognition and prevention.

    Wu, Vincent W C; Lam, Ying-Na

    2016-06-01

    Nasopharyngeal carcinoma (NPC) is endemic in southern China, and its incidence in Hong Kong is relatively high. Radiotherapy is the mainstay treatment for NPC due to its relatively high radiosensitivity and deep-seated anatomical position, which is not readily accessible by surgery. Although the technique of radiotherapy in NPC has been advancing and offers promising treatment outcome, complications around the irradiation areas are inevitable and the quality of life of the post-radiotherapy patients is often compromised. Trismus, which is defined as the restricted mouth opening or jaw movement due to the disorder of temporo-mandibular joint (TMJ), is one of the possible late complications for radiotherapy of NPC and is found in 5-17% of the post-radiotherapy (post-RT) patients. Trismus at early stage may only affect the speech, but in severe cases nutritional intake and oral hygiene condition may deteriorate seriously. This article reviewed the possible causes of radiation-induced TMJ damage, the various assessments including imaging modalities and possible treatments. The conclusion is that the availability of simple, yet effective examinations for trismus is essential for delaying the progression and restoring TMJ functions. Although there is no absolutely effective treatment for trismus, many supportive, restorative and palliative management are possible under different clinical situations.

    This study was designed to investigate the efficacy of the temporomandibular joint arthrocentesis with and without injection of sodium hyaluronate (SH) in the treatment of temporomandibular joint disorders. A total of sixty two TMJs in 34 males and 28 females aged 20-65 years comprised the study material. The patients' complaints were limited mouth opening, TMJ pain, and joint noises during function. Patients were randomly divided into 2 groups in which arthrocentesis plus intra-articular injection of sodium hyaluronate was performed in 1 group and only arthrocentesis was performed in the other group. Both groups contained patients with disc displacement with reduction and without reduction. Clinical evaluation of the patients was done before the procedure, immediately after the procedure, at 1 week and 1, 3 and 6 months postoperatively. Intensity of TMJ pain was assessed using visual analog scales. Maximal mouth opening and lateral jaw movements also were recorded at each follow-up visit. Both techniques increased maximal mouth opening, lateral movements, and function, while reducing TMJ pain and noise. Although patients benefitted from both techniques, arthrocentesis with injection of SH seemed to be superior to arthrocentesis alone.

    Full Text Available Anxiety disorders are highly prevalent among children and are associated with serious morbidity. Lifetime prevalence of paediatric anxiety disorders is about fifteen percent. Social phobia, generalized anxiety disorder and separation anxiety disorder are included in the triad of paediatric anxiety disorders. Specific phobia, obsessive compulsive disorder and post-traumatic stress disorder are also commonly seen in children. Overprotection by parents, parental death or separation, female sex, low educational status, family history of anxiety disorder, financial stress in family and adverse childhood experiences are risk factors for the development of anxiety disorders. If not diagnosed and managed at the earliest, paediatric anxiety disorders can cause life threatening problems in the future. Hence early and scientific management of anxiety disorders is essential. Cognitive behavioural therapy is the effective evidence based treatment for paediatric anxiety disorders.

    Correct functioning of the entire stomatognathic system is achieved by a compatible relationship of all its parts. Four determinants, by their mutual harmonious activity, dictate the function of the entire system: the teeth, periodontium with supporting structure, muscles, temporomandibular joint (TMJ) and CNS. In such a complex system a disorder of any integrative part causes disturbances also in other parts of the system. Changed functions can arise through organic disorder, and also iatrogenically by inadequate conservative, prosthetic, surgical or orthodontic therapy. For this reason it is often difficult to recognise the primary cause. The first responses of the system to the disorder are adaptive mechanisms which occur within one or more integrative parts, and depending on their intensity and duration symptoms grow more prominent. Tissue response can be ortho- or parafunctional. Attempts are made to exclude psychoemotional influences and the obstacle eliminated by either abrasion, clenching or grinding of the teeth. If the obstacle is not eliminated by abrasion, the cause of such functional disorder becomes the trigger for parafunctional activity. From a review of the relevant literature it can be concluded that parafunctional activity is caused by changed occlusion, with determined psychological habits of the patient and specific tissue response of the stomatognathic system. Therefore, therapy of these disorders is made more difficult and includes a multidisciplinary approach.

    Temporomandibular disorders are a form of musculoskeletal disorders, which reduce the function of stomatognathic system and they are related to some other diseases causing painful conditions and disorders of oral function. The aim of this paper is to describe a one year follow up clinical case of a female patient with comorbid multiple sclerosis and a relatively rare form of articular disc disorder. Primary clinical diagnostics encompassed manual methods of TMJ examination. Definite diagnosis included radiologic examination. Clinical hyperextensive condyle position was palpated bilaterally and subsequently confirmed by a functional panoramic radiograph of TMJ. The anterior displacement of disc with reduction was diagnosed by magnetic resonance and in the right joint there was a disc displacement upon excursive movement. From relevant literature, the relationship of a number of diseases that can be related to functional disorder of the orofacial system, such as multiple sclerosis, has been described from many aspects. Also, apart from the standard classification of one form of anterior displacement of the disc, made primarily by magnetic resonance, cases of disc displacement upon excursive mandibular movement can rarely be found in literature.

    Establishing the patient's clinical diagnosis depends on gathering as much information of the patient and his or her signs and symptoms as possible. This information can be gathered from history, physical and psychological examination, diagnostic analysis. It is also important to look upon pain as a disorder and to consider the relationship between pain and psychological factors. The differential diagnosis is constructed through a biopsychological model of illness rather than through a more traditional biomedical model of disease. To arrive at a consistently accurate clinical diagnosis in patients with TMJ and craniofacial pain, the technique of clinical diagnosis must be well defined, reliable and include examination of the head and the neck, cranial nerves and the stomatognathic system. The craniomandibular index provides a standardized examination of the stomatognathic system that has been tested on validity and reliability. This chapter focuses on the techniques of history taking clinical and psychological examination and diagnostic criteria for temporomandibular joint disorders and muscle pain.

    Background The main objective of this paper is to analyze the prevalence of each of the different clinical subtypes of temporomandibular disorders (TMD) in a sample of patients with this pathology. In addition, a second objective was to analyze their distribution according to gender. Material and Methods To this end, the results of 1603 patients who went to the Unit of Temporomandibular Disorders in the Córdoba Healthcare District because they suffered from this pathology were analyzed. In order to diagnose them, the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) were applied, analyzing the different Axis I subtypes (myopathy, discopathy and arthropathy) and obtaining the combined Axis I for each patient and the relation of all these variables according to gender. The null-hypothesis test confirmed the lack of connection between the gender variable and the different subtypes in the clinical analysis, and between the former and the combined Axis I of the RDC/TMD. Results The prevalence was high for the muscle disorders subtype in general, showing an 88.7% prevalence, while the presence of discopathies or arthropathies was much lower. Among discopathies, the most frequent ones were disc displacements with reduction, with 39.7% and 42.8% for the left and right temporomandibular joints (TMJ), respectively, while the prevalence of arthropathies was 26.3% for the right TMJ and 32.9% for the left TMJ. The bivariate analysis on the connection with gender reveals a p≥ 0.05 value for the muscle and arthralgia subtypes. Conclusions The patients seen at the TMD Unit where mostly middle-aged women whose main clinical axis subtype was the muscle disorder subtype. For their part, both discopathies and arthropathies, although present, are much less prevalent. Key words:RDCTMD, axis I, orofacial pain, temporomandibular disorders, gender. PMID:26615508

    Animal-assisted therapy (AAT) includes a set of nonpharmacological interventions aimed at improving human health through the use of trained or untrained animals. In recent decades, AAT has been trialed for different neurological and psychiatric disorders. In patients with dementia, interaction with animals seems to have a positive influence on aggressiveness and anxiety and to ameliorate quality of life and relationship skills. In psychiatric patients, AAT seems to increase motivation and self-esteem, improve prosocial conduct, and decrease behavioral problems. The aim of this study is to review the literature on AAT for elderly people with dementia and psychiatric disorders. Other fields of possible application for AAT are suggested.

    The aims of this study was to compare the diagnostic accuracy of Conventional Radiography (CR). Radionuclide Angiography (RNA). Planar Scintigraphy (PS) and Single Photon Emission Computed Tomography (SPECT) for the evaluation of temporomandibular joint (TMJ) disorder; and to show whether technetium-99m-MDP uptake on quantitative SPECT correlated with the symptom and/or signs. Three Phase Bone Scintigraphy (TPBS) and SPECT of both TMJ were performed in 51 patients (M : F = 10 : 41 mean age= 30.4 :28.6, respectively) with unilateral TMJ disorder after an intravenous injection of 25 mCi (925 MBq) of 99mTc-MDP. Data were analyzed by creating three regions of interest (ROIs) over designated areas both on the PS and SPECT: Lesion (L). Non-lesion(NL) which is contralateral to L and Background (BG). L/ NL and L/BG (=[(L-BG)/500,000] x 100 (%)] ratios were calculated for each patients. L/NL ratios on SPECT were compared according to the symptom/signs or not. There was a fair correlation of L/N values between three slice-and seven slice-added SPECT images (r=0.5124, p=0.006, y=0.5588 + 0.5414X). The percentages of symptoms or signs were: pain (76.5%), mouth opening limitation (49.0%), joint sound (39.2%), discomfort (43.1%), headache(27.5%), neck stiffness (21.6%), closed lock (5.9%) / tenderness (47.1%), joint click (54.9%) and limitation of maximum mouth opening (45.1%). The Sensitive of SPECT(86.3%) was better than PS(66.7%), RNA(27.5%), and CR(26.3%). According to the presence of symptom/sign or not, comparative analysis of L/NL ratios on SPECT showed a fair correlation in pain (1.16 : 1.11) mouth opening limitation (1.21 : 1.09), joint sound (1.19 : 1.08), discomfort (1.22 : 1.09), headache (1.19: 1.13), tenderness (1.16 : 1.14) and limitation of maximum mouth opening (1.16 : 1.13), but little correlation in neck stiffness (1.12 : 1.15), closed lock (1.06 : 1.15), dislocation (1.08 : 1.15) joint click (1.12 : 1.18). In conclusion, quantitative SPECT is the noninvasive

    Relatively little is known about the onset of bipolar disorder, yet the early illness course is already associated with significant morbidity and mortality. Therefore, characterizing the bipolar illness trajectory is key to risk prediction and early intervention advancement. In this narrative review, we discuss key findings from prospective longitudinal studies of the high-risk offspring of bipolar parents and related meta-analyses that inform us about the clinical trajectory of emerging bipolar disorder. Challenges such as phenotypic and etiologic heterogeneity and the non-specificity of early symptoms and syndromes are highlighted. Implications of the findings for both research and clinical practice are discussed. Bipolar disorder in young people at familial risk does not typically onset with a hypomanic or manic episode. Rather the first activated episode is often preceded by years of impairing psychopathological states that vary over development and across emerging bipolar subtype. Taking heterogeneity into account and adopting a more comprehensive approach to diagnosis seems necessary to advance earlier identification and our understanding of the onset of bipolar disorder.

    Oral healthcare providers have a clinical opportunity for early detection of disordered eating behaviors because they are often the first health professionals to observe overt oral and physical signs. Curricula regarding early recognition of this oral/systemic medical condition are limited in oral health educational programs. Web-based learning can supplement and reinforce traditional learning and has the potential to develop skills. The study purpose was to determine the efficacy of a theory-driven Web-based training program to increase the capacity of oral health students to perform behaviors related to the secondary prevention of disordered eating behaviors. Using the Reach, Effectiveness, Adoption, Implementation and Maintenance evaluation framework, a longitudinal group-randomized controlled trial involving 27 oral health classes from 12 oral health education programs in the United States was implemented to assess the efficacy of the Web-based training on attitudes, knowledge, self-efficacy and skills related to the secondary prevention of disordered eating behaviors. Mixed-model analysis of covariance indicated substantial improvements among students in the intervention group (effect sizes: 0.51-0.83) on all six outcomes of interest. Results suggest that the Web-based training program may increase the capacity of oral healthcare providers to deliver secondary prevention of disordered eating behaviors. Implications and value of using the Reach, Effectiveness, Adoption, Implementation and Maintenance framework are discussed.

    The current fourth paper on the International College of Neuropsychopharmacology guidelines for the treatment of bipolar disorder reports on the unmet needs that became apparent after an extensive review of the literature and also serves as a conclusion to the project of the International College of Neuropsychopharmacology workgroup. The systematic review of the literature that was performed to develop the International College of Neuropsychopharmacology guidelines for bipolar disorder identified and classified a number of potential shortcomings. Problems identified concerned the reliability and validity of the diagnosis of bipolar disorder and especially of bipolar depression. This, in turn, has profound consequences for early detection and correct treatment of the disorder. Another area that needs improvement is the unsatisfactory efficacy and effectiveness of therapeutic options, especially in special populations such as those with mixed features and rapid cycling course. Gender issues and adherence problems constitute an additional challenge. The literature suggests that while treatment providers are concerned more with treatment-related issues, patients and their caregivers worry more about issues pertaining to the availability of services and care, quality of life, and various types of burden. The workgroup identified additional unmet needs related to the current standard of research in bipolar disorder. These include the fragmentation of bipolar disorder into phases that are handled as being almost absolutely independent from each other, and thus the development of an overall therapeutic strategy on the basis of the existing evidence is very difficult. Trials are not always designed in a way that outcomes cover the most important aspects of bipolar disorder, and often the reporting of the results is biased and unsatisfactory. The data on combination treatments and high dosages are sparse, whereas they are common in real world practice. The workgroup endorses

    Full Text Available PURPOSE: To describe and evaluate normal rat temporomandibular joints from anatomic and histopathologic point of view and make a comparison between this joint in rats and humans. METHODS: Twelve male adult Wistar rats (12 same side joints were used in this procedure. The following anatomical structures were histologically evaluated in a qualitative fashion: condyle, disc, temporal bone, retrodiscal tissue and synovia. The macroscopical and microscopic study of the human TMJ was based on the current literature. RESULTS: The TMJ is surrounded by a thin capsule, consisting of fibrous tissue, and a synovial lining. The mandibular angle has a prominent shape. The glenoid fossa is flat, with no eminences. Histologically, the TMJ is composed of different tissues that comprise the mandibular head, mandibular fossa and fibrocartilaginous disc. A layer of hyaline cartilage covers the articulating cortical condyle and temporal bone. CONCLUSION:Morphologically and histologically, the articular structure of rats is, on the whole, similar to that of humans. In these animals there is no articular eminence.OBJETIVO: Descrever e avaliar a articulação temporomandibular de ratos sob o aspecto anatômico e histológico e realizar uma comparação entre esta articulação e a de humanos.

    One goal of this prospective longitudinal study was to identify new group A beta-hemolytic streptococcal infections (GABHS) in children and adolescents with Tourette syndrome (TS) and/or obsessive-compulsive disorder (OCD) compared with healthy control subjects. We then examined the power of GABHS infections and measures of psychosocial stress to predict future tic, obsessive-compulsive (OC), and depressive symptom severity. Consecutive ratings of tic, OC, and depressive symptom severity were obtained for 45 cases and 41 matched control subjects over a 2-year period. Clinical raters were blinded to the results of laboratory tests. Laboratory personnel were blinded to case or control status and clinical ratings. Structural equation modeling for unbalanced repeated measures was used to assess the sequence of new GABHS infections and psychosocial stress and their impact on future symptom severity. Increases in tic and OC symptom severity did not occur after every new GABHS infection. However, the structural equation model found that these newly diagnosed infections were predictive of modest increases in future tic and OC symptom severity but did not predict future depressive symptom severity. In addition, the inclusion of new infections in the model greatly enhanced, by a factor of three, the power of psychosocial stress in predicting future tic and OC symptom severity. Our data suggest that a minority of children with TS and early-onset OCD were sensitive to antecedent GABHS infections. These infections also enhanced the predictive power of current psychosocial stress on future tic and OC symptom severity. Copyright 2010 Society of Biological Psychiatry. Published by Elsevier Inc.

    Temporomandibular joint (TMJ) is one of the most complex joints of the human body. Due to its unique movement, in terms of combination of rotation and translator movement, disc of the joint plays an important role to maintain its normal function. In order to sustain the normal function of the TMJ, disc must be kept in proper position as well as maintain normal shape in all circumstances. Once the disc is not any more in its normal position during function of the joint, disturbance of the joint can be occurred which will lead to subsequent distortion of the disc. Shape of the disc can be influenced by many factors i.e.: abnormal function or composition of the disc itself. Etiology of the internal derangement of the disc remains controversial. Multifactorial theory has been postulated in most of previous manuscripts. Disc is composed of mainly extracellular matrix. Abnormal proportion of collagen type I & III may also leads to joint hypermobility which may be also a predisposing factor of this disorder. Thus it can be recognized as local manifestation of a systemic disorder. Different treatment modalities with from conservative treatment to surgical intervention distinct success rate have been reported. Recently treatment with extracellular matrix injection becomes more and more popular to strengthen the joint itself. Since multifactorial in character, the best solution of the treatment modalities should be aimed to resolve possible etiology from different aspects. Team work may be indication to reach satisfied results. Copyright © 2018. Published by Elsevier Taiwan.

    Clinical and radiographic characteristics of a subset of South East Asian temporomandibular disorder (TMD) patients with comorbid upper airway resistance syndrome (UARS) were documented in a multi-center prospective series of 86 patients (26 men and 60 women / mean age 35.7 years). All had excessive daytime sleepiness, high arousal index and Apnoea-Hypopnoea Index (AHI) temporomandibular joint (TMJ) arthralgia while 90·7% reported sleep bruxism (SB). Unlike patients with obstructive sleep apnoea (OSA), hypertension was uncommon (4·7%) while depression was prevalent at 68·6% with short REM latency of 25% documented in 79·6% and 57·6% of these depressed patients, respectively. 65·1% displayed a posteriorly displaced condyle at maximum intercuspation with or without TMJ clicking. Most exhibited a forward head posture (FHP) characterised by loss of normal cervical lordosis (80·2%), C0-C1 narrowing (38·4%) or an elevated hyoid position (50%), and 91·9% had nasal congestion. We postulate the TMD-UARS phenotype may have originally developed as an adaptive response to 'awake' disordered breathing during growth. Patients with persistent TMD and/or reporting SB should be screened for UARS and chronic nasal obstruction, especially when they also present with FHP. The lateral cephalogram is a useful tool in the differentiation of UARS from other OSA phenotypes. © 2017 John Wiley & Sons Ltd.

    This study was performed to find the relationship between pain and joint effusion using magnetic resonance imaging (MRI) in temporomandibular disorder (TMD) patients. The study subjects included 232 TMD patients. The inclusion criteria in this study were the presence of spontaneous pain or provoked pain on one or both temporomandibular joints (TMJs). The provoked pain was divided into three groups: pain on palpation (G1), pain on mouth opening (G2), and pain on mastication (G3). MRI examinations were performed using a 1.5-T MRI scanner. T1- and T2-weighted images with para-sagittal and para-coronal images were obtained. According to the T2-weighted image findings, the cases of effusions were divided into four groups: normal, mild (E1), moderate (E2), and marked effusion (E3). A statistical analysis was carried out using the chi2 test with SPSS (version 12.0, SPSS Inc., Chicago, IL, USA). Spontaneous pain, provoked pain, and both spontaneous and provoked pain were significantly related to joint effusion in TMD patients (p<0.05). However, among the various types of provoked pain, pain on palpation of the masticatory muscles and TMJ (G1) was not related to joint effusion in TMD patients (p>0.05). Spontaneous pain was related to the MRI findings of joint effusion; however, among the various types of provoked pain, pain on palpation of the masticatory muscles and TMJ was not related to the MRI findings of joint effusion. These results suggest that joint effusion has a significant influence on the prediction of TMJ pain.

    Full Text Available The cerebellum has been considered for a long time to play a role solely in motor coordination. However, studies over the past two decades have shown that the cerebellum also plays a key role in many motor, cognitive, and emotional processes. In addition, studies have also shown that the cerebellum is implicated in many psychiatric disorders including attention deficit hyperactivity disorder, autism spectrum disorders, schizophrenia, bipolar disorder, major depressive disorder and anxiety disorders. In this review, we discuss existing studies reporting cerebellar dysfunction in various psychiatric disorders. We will also discuss future directions for studies linking the cerebellum to psychiatric disorders.

    Full Text Available Abstract The Diagnostic and Statistical Manual (DSM of the American Psychiatric Association, currently in its fourth edition and considered the reference for the characterization and diagnosis of mental disorders, has undergone various developments since its inception in the mid-twentieth century. With the fifth edition of the DSM presently in field trials for release in 2013, there is renewed discussion and debate over the extent of its relative successes - and shortcomings - at iteratively incorporating scientific evidence on the often ambiguous nature and etiology of mental illness. Given the power that the DSM has exerted both within psychiatry and society at large, this essay seeks to analyze variations in content and context of various editions of the DSM, address contributory influences and repercussion of such variations on the evolving landscape of psychiatry as discipline and practice over the past sixty years. Specifically, we document major modifications in the definition, characterization, and classification of mental disorders throughout successive editions of the DSM, in light of shifting trends in the conceptualization of psychopathology within evolving schools of thought in psychiatry, and in the context of progress in behavioral and psychopharmacological therapeutics over time. We touch upon the social, political, and financial environments in which these changes took places, address the significance of these changes with respect to the legitimacy (and legitimization of what constitutes mental illness and health, and examine the impact and implications of these changes on psychiatric practice, research, and teaching. We argue that problematic issues in psychiatry, arguably reflecting the large-scale adoption of the DSM, may be linked to difficulties in formulating a standardized nosology of psychopathology.

    Neuroimaging has been involved in recent biological approaches with evidence for neurotic disorders in place of diagnostic criteria on Freud theory hitherto. This review describes the present states of brain imaging in those disorders. Emotion has such three bases for environmental stimuli as recognition/evaluation of causable factors, manifestation, and its control, each of which occurs in various different regions connected by neuro-net work in the brain. The disorders are regarded as abnormality of the circuit that can be imaged. Documented and discussed are the actual regions imaged by MRI and PET in panic disorder, social phobia, phobias to specified things, posttraumatic stress disorder and obsessive-compulsive disorder. The approach is thought important for elucidating not only the pathogenesis of the disorders but also the human emotional functions and mechanism of the mind, which may lead to a better treatment of the disorders in future.

    Recent work suggests sensory seeking predicts later social symptomatology through reduced social orienting in infants who are at high-risk for autism spectrum disorder (ASD) based on their status as younger siblings of children diagnosed with ASD. We drew on extant longitudinal data from a community sample of at-risk infants who were identified at 12 months using the First Year Inventory, and followed to 3-5 years. We replicate findings of Damiano et al. (in this issue) that a) high-risk infants who go on to be diagnosed with ASD show heightened sensory seeking in the second year of life relative to those who do not receive a diagnosis, and b) increased sensory seeking indirectly relates to later social symptomatology via reduced social orienting. We extend previous findings to show that sensory seeking has more clinical utility later in the second year of life (20-24 months) than earlier (13-15 months). Further, this study suggests that diminished attention disengagement at 12-15 months may precede and predict increased sensory seeking at 20-24 months. Findings add support for the notion that sensory features produce cascading effects on social development in infants at risk for ASD, and suggest that reduced attention disengagement early in life may set off this cascade.

    The US Preventive Services Task Force recommends that clinicians screen all adults for alcohol misuse and provide brief counseling to those engaged in risky or hazardous drinking. The World Health Organization's (WHO's) Alcohol Use Disorders Identification Test (AUDIT) is the most widely tested instrument for screening in primary health care. This paper describes the structural and functional features of the AUDIT and methodological problems with the validation of the alcohol consumption questions (AUDIT-C). The content, scoring, and rationale for a new version of the AUDIT (called the USAUDIT), adapted to US standard drink size and hazardous drinking guidelines, is presented. Narrative review focusing on the consumption elements of the AUDIT. Four studies of the AUDIT-C are reviewed and evaluated. The AUDIT has been used extensively in many countries without making the changes in the first three consumption questions recommended in the AUDIT User's Manual. As a consequence, the original WHO version is not compatible with US guidelines and AUDIT scores are not comparable with those obtained in countries that have different drink sizes, consumption units, and safe drinking limits. Clinical and Scientific Significance. The USAUDIT has adapted the WHO AUDIT to a 14 g standard drink, and US low-risk drinking guidelines. These changes provide greater accuracy in measuring alcohol consumption than the AUDIT-C.

  7. Future food.

    Wahlqvist, Mark L

    2016-12-01

    Food systems have changed markedly with human settlement and agriculture, industrialisation, trade, migration and now the digital age. Throughout these transitions, there has been a progressive population explosion and net ecosystem loss and degradation. Climate change now gathers pace, exacerbated by ecological dysfunction. Our health status has been challenged by a developing people-environment mismatch. We have regarded ecological conquest and innovative technology as solutions, but have not understood how ecologically dependent and integrated we are. We are ecological creatures interfaced by our sensoriness, microbiomes, shared regulatory (endocrine) mechanisms, immune system, biorhythms and nutritional pathways. Many of us are 'nature-deprived'. We now suffer what might be termed ecological health disorders (EHD). If there were less of us, nature's resilience might cope, but more than 9 billion people by 2050 is probably an intolerable demand on the planet. Future food must increasingly take into account the pressures on ecosystem-dependent food systems, with foods probably less biodiverse, although eating in this way allows optimal health; energy dysequilibrium with less physical activity and foods inappropriately energy dense; and less socially-conducive food habits. 'Personalised Nutrition', with extensive and resource-demanding nutrigenomic, metabolomic and microbiomic data may provide partial health solutions in clinical settings, but not be justified for ethical, risk management or sustainability reasons in public health. The globally prevalent multidimensional malnutritional problems of food insecurity, quality and equity require local, regional and global action to prevent further ecosystem degradation as well as to educate, provide sustainable livelihoods and encourage respectful social discourse and practice about the role of food.

    Decades of research and more than 20 randomized controlled trials show that Virtual Reality exposure therapy (VRET) is effective in reducing fear and anxiety. Unfortunately, few providers or patients have had access to the costly and technical equipment previously required. Recent technological advances in the form of consumer Virtual Reality (VR) systems (e.g. Oculus Rift and Samsung Gear), however, now make widespread use of VRET in clinical settings and as self-help applications possible. In this literature review, we detail the current state of VR technology and discuss important therapeutic considerations in designing self-help and clinician-led VRETs, such as platform choice, exposure progression design, inhibitory learning strategies, stimuli tailoring, gamification, virtual social learning and more. We illustrate how these therapeutic components can be incorporated and utilized in VRET applications, taking full advantage of the unique capabilities of virtual environments, and showcase some of these features by describing the development of a consumer-ready, gamified self-help VRET application for low-cost commercially available VR hardware. We also raise and discuss challenges in the planning, development, evaluation, and dissemination of VRET applications, including the need for more high-quality research. We conclude by discussing how new technology (e.g. eye-tracking) can be incorporated into future VRETs and how widespread use of VRET self-help applications will enable collection of naturalistic "Big Data" that promises to inform learning theory and behavioral therapy in general.

    To analyze whether gender, self-reported bruxism, and variations in dental occlusion predicted incidence and persistence of temporomandibular disorder (TMD) during a 2-year period. The study population comprised 280 dental students at Umeå University in Sweden. The study design was that of a case-control study within a 2-year prospective cohort. The investigation comprised a questionnaire and a clinical examination at enrolment and at 12 and 24 months. Cases (incidence) and controls (no incidence) were identified among those without signs and symptoms of TMD at the start of the study. Cases with 2-year persistence of signs and symptoms of TMD were those with such signs and symptoms at all three examinations. Clinical registrations of baseline variables were used as independent variables. Odds ratio estimates and 95% confidence intervals of the relative risks of being a case or control in relation to baseline registrations were calculated using logistic regression analyses. The analyses revealed that self-reported bruxism and crossbite, respectively increased the risk of the 2-year cumulative incidence and duration of temporomandibular joint (TMJ) signs or symptoms. Female gender was related to an increased risk of developing and maintaining myofascial pain. Signs of mandibular instability increased the risk of maintained TMD signs and symptoms during the observation period. This 2-year prospective observational study indicated that self-reported bruxism and variations in dental occlusion were linked to the incidence and persistence of TMJ signs and symptoms to a higher extent than to myofascial pain.

    Lateral pterygoid muscle (LPM) plays an important role in jaw movement and has been implicated in Temporomandibular disorders (TMDs). Migraine has been described as a common symptom in patients with TMDs and may be related to muscle hyperactivity. This study aimed to compare LPM volume in individuals with and without migraine, using segmentation of the LPM in magnetic resonance (MR) imaging of the TMJ. Twenty patients with migraine and 20 volunteers without migraine underwent a clinical examination of the TMJ, according to the Research Diagnostic Criteria for TMDs. MR imaging was performed and the LPM was segmented using the ITK-SNAP 1.4.1 software, which calculates the volume of each segmented structure in voxels per cubic millimeter. The chi-squared test and the Fisher's exact test were used to relate the TMD variables obtained from the MR images and clinical examinations to the presence of migraine. Logistic binary regression was used to determine the importance of each factor for predicting the presence of a migraine headache. Patients with TMDs and migraine tended to have hypertrophy of the LPM (58.7%). In addition, abnormal mandibular movements (61.2%) and disc displacement (70.0%) were found to be the most common signs in patients with TMDs and migraine. In patients with TMDs and simultaneous migraine, the LPM tends to be hypertrophic. LPM segmentation on MR imaging may be an alternative method to study this muscle in such patients because the hypertrophic LPM is not always palpable.

    This study was performed to find the relationship between pain and joint effusion using magnetic resonance imaging (MRI) in temporomandibular disorder (TMD) patients. The study subjects included 232 TMD patients. The inclusion criteria in this study were the presence of spontaneous pain or provoked pain on one or both temporomandibular joints (TMJs). The provoked pain was divided into three groups: pain on palpation (G1), pain on mouth opening (G2), and pain on mastication (G3). MRI examinations were performed using a 1.5-T MRI scanner. T1- and T2-weighted images with para-sagittal and para-coronal images were obtained. According to the T2-weighted image findings, the cases of effusions were divided into four groups: normal, mild (E1), moderate (E2), and marked effusion (E3). A statistical analysis was carried out using the chi2 test with SPSS (version 12.0, SPSS Inc., Chicago, IL, USA). Spontaneous pain, provoked pain, and both spontaneous and provoked pain were significantly related to joint effusion in TMD patients (p 0.05). Spontaneous pain was related to the MRI findings of joint effusion; however, among the various types of provoked pain, pain on palpation of the masticatory muscles and TMJ was not related to the MRI findings of joint effusion. These results suggest that joint effusion has a significant influence on the prediction of TMJ pain.

    Whiplash injury to the neck is often considered a significant risk factor for development of temporomandibular disorders (TMD), and has been proposed to produce internal derangements of the temporomandibular joint (TMJ). Few studies, however, have examined TMD-related pain in acute whiplash patients compared with a matched control group. The aim of the present study was to assess pain and sensorimotor function in the craniofacial region in an unselected group of patients sustaining a motor vehicle accident involving a rear collision. Prospectively, 19 acute whiplash patients exposed to a motor vehicle accident involving a rear collision participated in a study of TMD. The control group consisted of 20 age- and gender-matched ankle-injury patients. Participants were seen within 4 weeks and again at 6 months post-injury. The masticatory system was examined in accordance with the research diagnostic criteria. Participants underwent structured interviews, filled out the McGill Pain Questionnaire (MPQ), and had their masticatory system examined by a trained dentist, blinded to their diagnosis. Pain detection threshold (PDT) to pressure stimuli, and maximal voluntary occlusal force (MVOF) were obtained at each visit. One whiplash patient and 1 ankle-injury patient had jaw pain at the first visit. Palpation scores of the TMJ and the summated palpation scores only tended to be higher in patients sustaining a whiplash injury than in ankle-injury controls at the first visit. However, MPQ, TMD symptoms and signs, MVOF and PDT were not significantly different in whiplash-injury and ankle-injury patients after 4 weeks and 6 months. TMD pain after whiplash injury and ankle injury is rare, suggesting that whiplash injury is not a major risk factor for the development of TMD problems. Further studies are needed to identify which other factors may contribute to TMD pain.

    Full Text Available This article was designed to report the current status of temporomandibular joint disorders (TMDs and the therapeutic system on the basis of a series of clinical, biomechanical, histological and biochemical studies in our research groups. In particular, we have focused on the association of degenerative changes of articular cartilage in the mandibular condyle and the resultant progressive condylar resorption with mechanical stimuli acting on the condyle during the stomatognathic function. In a clinical aspect, the nature and prevalence of TMDs, association of malocclusion with TMDs, association of condylar position with TMDs, association of craniofacial morphology with TMDs, and influences of TMDs, TMJ-osteoarthritis (TMJ-OA in particular, were examined. In a biomechanical aspect, the nature of stress distribution in the TMJ from maximum clenching was analyzed with finite element method. In addition, the pattern of stress distribution was examined in association with varying vertical discrepancies of the craniofacial skeleton and friction between the articular disk and condyle. The results demonstrated an induction of large compressive stresses in the anterior and lateral areas on the condyle by the maximum clenching and the subsequent prominent increases in the same areas of the mandibular condyle as the vertical skeletal discrepancy became more prominent. Increase of friction at the articular surface was also indicated as a cause of larger stresses and the relevant disk displacement, which further induced an increase in stresses in the tissues posterior to the disks, indicating an important role of TMJ disks as a stress absorber. In a histological or biological aspect, increase in TMJ loading simulated by vertical skeletal discrepancy, which has already been revealed by the preceding finite element analysis or represented by excessive mouth opening, produced a decrease in the thickness of cartilage layers, an increase in the numbers of

  2. Temporomandibular disorders: Old ideas and new concepts.

    List, Thomas; Jensen, Rigmor Højland

    2017-06-01

    Background Temporomandibular disorders (TMD) is an umbrella term for pain and dysfunction involving the masticatory muscles and the temporomandibular joints (TMJs). TMD is the most common orofacial pain condition. Its prominent features include regional pain in the face and preauricular area, limitations in jaw movement, and noise from the TMJs during jaw movements. TMD affects up to 15% of adults and 7% of adolescents. Chronic pain is the overwhelming reason that patients with TMD seek treatment. TMD can associate with impaired general health, depression, and other psychological disabilities, and may affect the quality of life of the patient. Assessment Evaluations indicate that the recently published Diagnostic Criteria for TMD (DC/TMD) are reliable and valid. These criteria cover the most common types of TMD, which include pain-related disorders (e.g., myalgia, headache attributable to TMD, and arthralgia) as well as disorders associated with the TMJ (primarily disc displacements and degenerative disease). As peripheral mechanisms most likely play a role in the onset of TMD, a detailed muscle examination is recommended. The persistence of pain involves more central factors, such as sensitization of the supraspinal neurons and second-order neurons at the level of the spinal dorsal horn/trigeminal nucleus, imbalanced antinociceptive activity, and strong genetic predisposition, which also is included in DC/TMD. Conclusion The etiology is complex and still not clearly understood, but several biological and psychosocial risk factors for TMD have been identified. Several studies indicate that patients with TMD improve with a combination of noninvasive therapies, including behavior therapy, pharmacotherapy, physical therapy, and occlusal appliances. More stringently designed studies, however, are needed to assess treatment efficacy and how to tailor treatment to the individual patient.

    Temporomandibular disorders (TMDs) are mostly inflammatory conditions widespread in the population. Previous studies have shown positive effects of either laser or light-emitting diode (LED) phototherapies on treating TMDs, but their action and mechanism in the inflammatory infiltrate of the temporomandibular joint are still poorly understood. The aim of this study was to assess, through histological analysis, the effectiveness of using laser light (λ 780 nm, 70 mW, continous wave (CW), 10 J) and LED (λ 850 ± 10 nm, 100 mW, CW, 10 J) on the inflammation of the temporomandibular joint of rats induced by carrageenan. Forty-five animals were divided into three groups with five animals each according to the experimental times of 2, 3, and 7 days: inflammation, inflammation+laser phototherapy, and inflammation+LED phototherapy. The first irradiation was performed 24 h after induction with an interval of 48 h between sessions. After animal death, specimens were processed and stained with hematoxylin-eosin (HE) and picrosirius. Then, the samples were examined histologically. Data were statistically analyzed. The inflammation group showed mild to moderate chronic inflammatory infiltrate between bone trabecules of the condyle. Over the time course of the study in the laser group, the region of the condyle presented mild chronic inflammation and intense vascularization. In the LED group, the condyle showed aspects of normality and absence of inflammation in some specimens. In all the time points, the laser-irradiated groups showed greater amount of collagen deposition in the condyle (p = 0.04) and in the disc (p = 0.03) when compared to the inflammation and LED groups, respectively. Laser- and LED-treated groups demonstrate a smaller number of layers of the synovial membrane when compared to the non-irradiated groups. It was concluded that, in general, laser and LED phototherapies resulted in a reduction of inflammatory infiltrate in the

    Full Text Available Abstract This review explores the aetiology of temporomandibular disorders and discusses the controversies in variable treatment modalities. Pathologies of the temporomandibular joint (TMJ and its' associated muscles of mastication are jointly termed temporomandibular disorders (TMDs. TMDs present with a variety of symptoms which include pain in the joint and its surrounding area, jaw clicking, limited jaw opening and headaches. It is mainly reported by middle aged females who tend to recognize the symptoms more readily than males and therefore more commonly seek professional help. Several aetiological factors have been acknowledged including local trauma, bruxism, malocclusion, stress and psychiatric illnesses. The Research Diagnostic Criteria of the Temporomandibular Disorders (RDC/TMD is advanced to other criteria as it takes into consideration the socio-psychological status of the patient. Several treatment modalities have been recommended including homecare practices, splint therapy, occlusal adjustment, analgesics and the use of psychotropic medication; as well as surgery, supplementary therapy and cognitive behavioural therapy. Although splint therapy and occlusal adjustment have been extensively used, there is no evidence to suggest that they can be curative; a number of evidence-based trials have concluded that these appliances should not be suggested as part of the routine care. Surgery, except in very rare cases, is discouraged since it is the most invasive alternative; recent studies have shown healthier outcome with cognitive behavioural therapy.

    Full Text Available World Health Organization (WHO in the year 2000 have identified major depressive disorder ranks as the fourth leading cause of death in the world. WHO also estimates that in 2020, the disorder will increase to second only to ischemic heart disease. People at high risk of first occurrence of depression are those who have a family history. Depression can happen to anyone and at all ages, ranging in age from children, young adults up to old age. This paper will discuss the literature review of an overview of depression and itsmanagement in dentistry. Patients with major depressive disorder may have abnormalities in the oral cavity affected by lack of oral hygiene as well as a manifestation of mental disorder and its treatment. Dental and oral management conducted in accordance with procedures and have to be carried out carefully especially to patients with mental disorders such as depression. Tooth decayed, gingivitis, xerostomia, oral candidiasis, oral lesion, and TMJ disorder are clinical findings in depressed patient, so as dentists may cooperate with psychiatrists in providing comprehensive treatment to improve quality of life of the patients.

    Bruxism has been defined as a diurnal or nocturnal parafunctional habit. Etiology of bruxism has remained controversial and some investigators believe that psychological factors may play a major role in promoting and perpetuating this habit. The aim of this case-control study was to assess the existence of an association between bruxism and psychosocial disorders in adolescents., Participants were chosen among 114, 12-14 year old students (girls). They were divided into two groups, bruxers and nonbruxers, on the basis of both validated clinical criteria and interview with each patient. A few participants were excluded on the basis of presence of systemic disorders, TMJ disorders, other oral habits, primary teeth, defective restorations and premature contacts. Following matching of two groups in regard to parent's age and education, mother's marital status, child support status, mother's employment status, and socio-economical status, 25 cases and 25 controls were enlisted. A self report validated questionnaire (YSR, 11-18 yr) was then filled out by both groups for the evaluation of 12 psychosocial symptoms. Remarkable differences in certain psychosocial aspects were found between the two groups. Prevalence of psychosocial disorders including Thought Disorders (P bruxism and psychosocial disorders has been provided.

    Aim . Headache is one of the most common diseases associated with Temporomandibular Disorders (TMDs). The aim of this study was to evaluate, retrospectively, if headache influences TMD's symptoms. Material and Methods . A total sample of 1198 consecutive TMD patients was selected. After a neurological examination, a diagnosis of headache, according to the latest edition of the International Classification of Headache Disorders, was performed in 625 subjects. Patients were divided into two groups based on presence/absence of headache: Group with Headache (GwH) and Group without Headache (GwoH). Descriptive statistics and Chi-square index were performed. Results . Sociodemographic (gender, marital status, and occupation) and functional factors, occlusion (occlusal and skeletal classes, dental formula, and occlusal abnormalities), and familiar pain did not show a statistically significant correlation in either group. Intensity and frequency of neck pain, arthralgia of TMJ, and myalgia showed higher correlation values in GwH. Conclusion . This study is consistent with previous literature in showing a close relationship between headache and TMD. All data underlines that headache makes pain parameters more intense and frequent. Therefore, an early and multidisciplinary treatment of TMDs should be performed in order to avoid the overlay of painful events that could result in pain chronicity.

    We assessed and compared the diagnostic accuracy of two sets of diagnostic criteria for headache secondary to temporomandibular disorders (TMD). In 373 headache subjects with TMD, a TMD headache reference standard was defined as: self-reported temple headache, consensus diagnosis of painful TMD and replication of the temple headache using TMD-based provocation tests. Revised diagnostic criteria for Headache attributed to TMD were selected using the RPART (recursive partitioning and regression trees) procedure, and refined in half of the data set. Using the remaining half of the data, the diagnostic accuracy of the revised criteria was compared to that of the International Headache Society's International Classification of Headache Diseases (ICHD)-II criteria A to C for Headache or facial pain attributed to temporomandibular joint (TMJ) disorder. Relative to the TMD headache reference standard, ICHD-II criteria showed sensitivity of 84% and specificity of 33%. The revised criteria for Headache attributed to TMD had sensitivity of 89% with improved specificity of 87% (p headache that is changed with jaw movement, function or parafunction and (2) provocation of that headache by temporalis muscle palpation or jaw movement. Having significantly better specificity than the ICHD-II criteria A to C, the revised criteria are recommended to diagnose headache secondary to TMD.

    Full Text Available Sleep Bruxism is a significant etiology of temporomandibular disorder (TMD and causes many dental or oral problems such as tooth wear or facet. There is no study analyzing the relationship between sleep bruxism and TMD. Objective: To investigate any relationship between occlusal grinding pattern during sleep bruxism and temporomandibular disorder. Methods: A cross-sectional study involving 30 sleep bruxism patients attended the Faculty Dentistry Universitas Indonesia Teaching Hospital (RSGMP FKG UI. Completion of 2 forms of ID-TMD index and questionnaire from American Academy of Sleep Medicine were done. BruxChecker was fabricated and used for two nights to record the occlusal grinding pattern. The occlusal grinding pattern was categorized into laterotrusive grinding (LG and mediotrusive side. Further divisons of LG were: incisor-canine (IC, incisor-caninepremolar (ICP and incisor-canine-premolar-molar (ICPM. Mediotrusive side was classified as mediotrusive contact (MC and mediotrusive grinding (MG. Results: It was found that occlusal grinding pattern in non-TMD subjects were IC+MC, in subjects with mild TMD were ICP+MG and in subjects with moderate TMD were ICP+MG and ICPM+MG. TMJ was more significantly affected by ICP and ICPM grinding pattern than that of IC. Conclusion: There was a significant relationship between occlusal grinding pattern during sleep bruxism and TMD.DOI: 10.14693/jdi.v20i2.149

    A 31-year-old male with severe limitation of mouth opening was referred to our department of Chonbuk National University Hospital. The physical status of the patient was hyposthenic. Extraoral examination showed no condylar movement of the both temporomandibular joints, no pain, no faical swelling or paresthesia. Intraoral examination showed several cervical caries on the upper anterior teeth, and gingival swelling on the whole dentition. Transcranial view showed no condylar movement, and narrowing of joint spaces. Chest P-A view showed straightening of thoracic, lumbar spine, and squaring of vertebrae of the same spines. Conventional lateral radiograph of cervical spine showed calcification of the intervertebral ligament. Computed tomograph showed extensive bone formation between temporal bone and the both condylar heads. Labortory findings showed positive reaction on HLA-B27 histocompatibility antigen and increased level of IgA, IgG, ESR. Based on the clinical, radiographic, and the labortary findings, final diagnosis was made as bony ankylosis of the both temporomandibular joints secondary to ankylosing spondylitis.

    Issues regarding future development by oil and gas companies in Canada's Arctic and the Beaufort Sea were discussed. It was suggested in the Berger report that Northern development should be under the control of the people whose lives and economy are being changed. Aboriginal people are now much more sophisticated politically, and have a better understanding of what is involved. Most of them would like the financial benefits from development, but the development would have to be on their terms. Most people involved with Arctic oil exploration feel that there is enough oil in the Arctic to warrant production. (Reserves in the Beaufort Sea are estimated at two billion barrels of good quality oil). If development were to continue, there exist two methods of transportation to move the oil to market. Gulf, Imperial Oil and Panarctic favour the use of pipelines, whereas Dome Petroleum Ltd. favours the use of ice-breaking tankers. In each case the favored option seems to depend upon the location of the company's leases, the capital and operating costs, and the potential environmental impacts. Undoubtedly, any future development will be guided by the scientific information and technical expertise of oil industry pioneers of the 1960s and the 1970s, and the wisdom gained from the experiences of the many participants whose views and insights are recorded in this book

    The immune system is a key element in the organism's defence system and participates in the maintenance of homeostasis. There is growing interest in the aetiopathogenic and prognostic implications of the immune system in mental disorders, as previous studies suggest the existence of a dysregulation of the immune response and a pro-inflammatory state in patients with mental disorders, as well as an increased prevalence of neuropsychiatric symptoms in patients suffering from autoimmune diseases or receiving immune treatments. This study aims to conduct a narrative review of the scientific literature on the role of Psychoneuroimmunology in mental disorders, with special focus on diagnostic, prognostic and therapeutic issues. The development of this body of knowledge may bring in the future important advances in the vulnerability, aetiopathogenic mechanisms, diagnosis and treatment of some mental disorders.

    Full Text Available INTRODUCTION: Degenerative changes in Temporomandibular Joint (TMJ have increased in prevalence and severity over the years. Within this context, it's necessary to obtain safe and effective therapies for control and management of the patient in cases of osteoarthritis and osteoarthrosis of the TMJ. Therapeutic options range from intra-articular infiltration protocols, occlusal splints, pharmacological therapies and physiotherapy and educational measures. The alternative treatment with structure-modifying agents, like as chondroitin and glucosamine sulphates, showed promising results, and especially safety. Thus, through a systematic literature review, this study aimed to analyze and discuss effectiveness and safety of chondroitin and glucosamine in degenerative changes of the TMJ. METHODS: Survey in research bases MEDLINE, Cochrane, EMBASE, Pubmed, Lilacs and BBO, between the years of 1966 and January 2009, with focus in randomized clinical trial (RCTs and quasi-randomized clinical trials, systematic reviews and meta-analysis. RESULTS: After application of the inclusion criteria 2 articles were selected, both randomized controlled double-blind clinical trials, which evaluated the effectiveness of chondroitin and glucosamine in degenerative changes of the TMJ. CONCLUSIONS: There is the necessity of further RCT, with representative samples and long follow-up time, to obtainment more precise cause-effect relationships and to achieve an effective and objective protocol involving chondroitin and glucosamine in cases of degenerative changes of the TMJ.INTRODUÇÃO: as alterações degenerativas da Articulação Temporomandibular (ATM têm aumentado em prevalência e em severidade ao longo dos anos.

    Headache is a common symptom, that can be extremely disabling, affecting 26 million of patients only in Italy. ICHD-II has reported two categories: "primary headaches" and "secondary headaches". Temporomandibular joint disorders can lead to a secondary headaches. We want to evaluate the prevalence and clinical features of headache among a series of patients having temporomandibular joint disorders and we illustrate the evolution of headache following medical treatament of temporomandibular joint (TMJ) disorders. This is a retrospective study carried out on chart review of 426 consecutive patients with various degrees of temporomandibular disorders and treated with medical devices from 2007 to 2011. Headache was reported by 73 patients (17.14%). Headache was observed in 36 of 51 patients with lock and in 32 out of 130 patients with mandibular deflections (Table I). The remaining 5 patients with headache had articular noise. Headache is not a rare finding in a population with temporomandibular dysfunctions and is more often a tension-type rather than trigeminal headache.

    Whiplash injury can cause internal derangement of the temporomandibular joint (TMJ) and lead to temporomandibular disorders (TMDs). Our aim was to evaluate whether the initial clinical findings in TMD patients with whiplash injury are correlated with their magnetic resonance imaging (MRI) characteristics. This case-control study involved 219 patients (135 women, 84 men; mean age: 37.84 years) who visited our orofacial pain clinic with TMD; TMD was diagnosed using the diagnostic criteria for TMD Axis I. Patients were categorized into three groups based on the presence and type of macrotrauma: in the "wTMD" group, patients had suffered whiplash injury; patients in the "pTMD" group had post-traumatic TMD; the "iTMD" group comprised patients who had presented with TMD symptoms and had sustained no macrotrauma. We investigated the presence of disk displacement, effusion, disk deformity, and condylar degeneration, and changes in the lateral pterygoid muscle (LPM). To evaluate the severity of TMD pain and objectively analyze symptoms, we used a visual analog scale (VAS), palpation index (PI), neck PI, dysfunction index, and craniomandibular index (CMI). The VAS scores, and the severity indexes of the TMD including PI, neck PI, and CMI were highest in the wTMD patients. Atrophy of the LPM was most commonly seen in the wTMD group, as was disk deformity. In wTMD patients only, VAS score was significantly correlated with stress; it was correlated with headache in wTMD and iTMD patients. The clinical symptoms of TMD were not correlated with MRI findings in the wTMD group. However, alterations in the LPM were strongly correlated with disk displacement. If clinicians recognize alterations in the LPM and disk displacement in the TMJ, they will better understand the clinical symptoms and pathophysiology of TMD with whiplash injury. Whiplash injury may lead to TMD via different mechanisms from other macrotraumas.

    The Temporo-Mandibular Disorders (TMD) are a set of dysfunctional patterns concerning the temporo-mandibular joints (TMJ) and the masticatory muscles; its main symptom is pain, probably caused by inflammatory changes in the synovial membrane, alterations in the bone marrow of the mandibular condyle and impingement and compression. The aim of this preliminary study was to investigate the effectiveness in the TMD pain reduction of a new laser device recently proposed by the commerce that, due to its reduced dimensions and to be a class I laser according the ANSI classification, may be used at home by the patient himself. Twenty-four patients with TMD were randomly selected: the inclusion criteria for the sample was the diagnosis of mono- or bi-lateral TMD, with acute pain restricted to the joint area, associated with the absence of any muscle tenderness during palpation. The patients were randomly assigned to two groups: Group 1 (12 patients): patients receiving real LLLT (experimental group). Group 2 (12 patients): patients receiving inactive laser (placebo group). The treatment was performed once a day for two weeks with an 808 nm diode laser by the patient himself with irradiation of the cutaneous zone corresponding to the TMJ for 15 minutes each side. Each patient was instructed to express its pain in a visual analogue scale (VAS) making a perpendicular line between the two extremes representing the felt pain level. Statistical analysis was realized with GraphPad Instat Software, where Ptemporo-mandibular diseases by an at home self administered laser device. RESULTS are encouraging but they will have to be confirmed by greater studies.

    The aim of this study was to determine whether T.M.J. tomographic examination yielded significant difference in condyle positions among asymptomatic, myalgia, derangement, and arthrosis group of T.M.J. disorders. The author obtained sagittal linear tomograms of right and left T.M.Js. of 36 asymptomatic, 22 myalgia, 54 derangement, and 31 arthrosis patients taken at serial lateral, central, and medial sections in the intercuspal position after submentovertex radiographs analyzed. With the dual linear measurements of the posterior and anterior interarticular space, condyle positions were mathematically expressed as proportion. All data from these analysis was recorded and processed statistically. The results were obtained as follows: 1. In asymptomatic group, radiographically concentric condyle position was found in 50.0% to 65.4% of subjects, with a substance range of variability. No significant differences existed between men and women and also between right and left T.M.Js. for condyle position. 2. In women, significant difference for mean condyle position of left lateral section of each diagnostic category existed between derangement and myalgia groups (P< .05). Also that of left central section existed between derangement and myalgia group, and that of left medial section existed between derangement and myalgia groups (P< . 05). 3. In main-symptom side, condyle position in myalgia group was more concentric, and condyle position in derangement and group was more posterior. This showed significant differences between derangement and myalgia groups in lateral, central, and medial sections of main symptom side, and only between derangement and myalgia groups in central section of contra-lateral sides (P< .05). Condyle position in arthrosis group was broadly distributed among all positions. 4. In contra-lateral side, significant difference for mean condyle position of central section of each symptomatic group existed between derangement and myalgia group (P< .05

    Eating disorders, especially anorexia nervosa and bulimia nervosa have been classically described in young females in Western population. Recent research shows that they are also seen in developing countries including India. The classification of eating disorders has been expanded to include recently described conditions like binge eating disorder. Eating disorders have a multifactorial etiology. Genetic factor appear to play a major role. Recent advances in neurobiology have improved our understanding of these conditions and may possibly help us develop more effective treatments in future. Premorbid personality appears to play an important role, with differential predisposition for individual disorders. The role of cultural factors in the etiology of these conditions is debated. Culture may have a pathoplastic effect leading to non-conforming presentations like the non fat-phobic form of anorexia nervosa, which are commonly reported in developing countries. With rapid cultural transformation, the classical forms of these conditions are being described throughout the world. Diagnostic criteria have been modified to accommodate for these myriad presentations. Treatment of eating disorders can be quite challenging, given the dearth of established treatments and poor motivation/insight in these conditions. Nutritional rehabilitation and psychotherapy remains the mainstay of treatment, while pharmacotherapy may be helpful in specific situations. PMID:26330646

    Orthodontists are fully prepared to treat the problems of occlusion that they are called upon to deal with every day. On the other hand temporo-mandibular joint disorders present more obscure difficulties from the point of view of detection and diagnosis as well the management of their treatment. That is why a profound understanding of the anatomical and physiological functioning of the temporo-mandibular joint has become indispensable for today's orthodontists who are now asked to detect and diagnose an assortment of TMJ disturbances whose etiology may vary greatly. By performing a rigorous diagnostic procedure, based on a thorough clinical examination supported by careful axiographic and radiological studies, of temporo-mandibular malfunctioning and its underlying etiological causes, which are primarily dento-alveolar and occlusal in nature, orthodontists will be able to adopt an appropriate therapeutic approach that might be purely orthodontic or multi-disciplinary and carried out with the collaboration of specialists in occlusion, oral surgery, and even osteopathy.

    Psychiatry includes the assessment, treatment, and prevention of complex brain disorders, such as depression, bipolar disorder, anxiety disorders, schizophrenia, developmental disorders (e.g., autism), and neurodegenerative disorders (e.g., Alzheimer dementia). Its core mission is to prevent and alleviate the distress and impairment caused by these disorders, which account for a substantial part of the global burden of illness-related disability. Psychiatry is grounded in clinical neuroscience. Its core mission, now and in the future, is best served within this context because advances in assessment, treatment, and prevention of brain disorders are likely to originate from studies of etiology and pathophysiology based in clinical and translational neuroscience. To ensure its broad public health relevance in the future, psychiatry must also bridge science and service, ensuring that those who need the benefits of its science are also its beneficiaries. To do so effectively, psychiatry as clinical neuroscience must strengthen its partnerships with the disciplines of public health (including epidemiology), community and behavioral health science, and health economics.The authors present a Strengths, Weaknesses, Opportunities, and Threats (SWOT) analysis of psychiatry and identify strategies for strengthening its future and increasing its relevance to public health and the rest of medicine. These strategies encompass new approaches to strengthening the relationship between psychiatry and neurology, financing psychiatry's mission, emphasizing early and sustained multidisciplinary training (research and clinical), bolstering the academic infrastructure, and reorganizing and refinancing mental health services both for preventive intervention and cost-effective chronic disease management.

    In recent years, a number of neurocognitive models stemming from psychiatry and psychology schools of thought have conceptualized the pathophysiology of mood disorders in terms of dysfunctional neural mechanisms that underpin and drive neurocognitive processes. Though these models have been useful for advancing our theoretical understanding and facilitating important lines of research, translation of these models and their application within the clinical arena have been limited-partly because of lack of integration and synthesis. Cognitive neuroscience provides a novel perspective for understanding and modeling mood disorders. This selective review of influential neurocognitive models develops an integrative approach that can serve as a template for future research and the development of a clinically meaningful framework for investigating, diagnosing, and treating mood disorders. A selective literature search was conducted using PubMed and PsychINFO to identify prominent neurobiological and neurocognitive models of mood disorders. Most models identify similar neural networks and brain regions and neuropsychological processes in the neurocognition of mood, however, they differ in terms of specific functions attached to neural processes and how these interact. Furthermore, cognitive biases, reward processing and motivation, rumination, and mood stability, which play significant roles in the manner in which attention, appraisal, and response processes are deployed in mood disorders, are not sufficiently integrated. The inclusion of interactions between these additional components enhances our understanding of the etiology and pathophysiology of mood disorders. Through integration of key cognitive functions and understanding of how these interface with neural functioning within neurocognitive models of mood disorders, a framework for research can be created for translation to diagnosis and treatment of mood disorders. © 2015 John Wiley & Sons A/S.

    Eating disorders are characterized by aberrant patterns of eating behavior, including such symptoms as extreme restriction of food intake or binge eating, and severe disturbances in the perception of body shape and weight, as well as a drive for thinness and obsessive fears of becoming fat. Eating disorder is an important cause for physical and psychosocial morbidity in young women. Patients with eating disorders have a deficit in the cognitive process and functional abnormalities in the brain system. Recently, brain-imaging techniques have been used to identify specific brain areas that function abnormally in patients with eating disorders. We have discussed the clinical and cognitive aspects of eating disorders and summarized neuroimaging studies of eating disorders.

    Gambling disorders, including pathological gambling and problem gambling, have received increased attention from clinicians and researchers over the past three decades since gambling opportunities have expanded around the world. This Seminar reviews prevalence, causes and associated features, screening and diagnosis, and treatment approaches. Gambling disorders affect 0·2-5·3% of adults worldwide, although measurement and prevalence varies according to the screening instruments and methods used, and availability and accessibility of gambling opportunities. Several distinct treatment approaches have been favourably evaluated, such as cognitive behavioural and brief treatment models and pharmacological interventions. Although promising, family therapy and support from Gamblers Anonymous are less well empirically supported. Gambling disorders are highly comorbid with other mental health and substance use disorders, and a further understanding is needed of both the causes and treatment implications of this disorder.

It is a chronic disorder with an early age at onset and a lifelong impact. Yet it is underrecognized and poorly studied. Little is known regarding the most effective treatment. The impetus for research into this condition has waxed and waned, possibly due to concerns regarding its distinctiveness from other disorders, especially social anxiety disorder (SAD, schizoid personality disorder, and dependent personality disorder. The prevailing paradigm subscribes to the “severity continuum hypothesis”, in which AVPD is viewed essentially as a severe variant of SAD. However, areas of discontinuity have been described, and there is support for retaining AVPD as a distinct diagnostic category. Recent research has focused on the phenomenology of AVPD, factors of possible etiological significance such as early parenting experiences, attachment style, temperament, and cognitive processing. Self-concept, avoidant behavior, early attachments, and attachment style may represent points of difference from SAD that also have relevance to treatment. Additional areas of research not focused specifically on AVPD, including the literature on social cognition as it relates to attachment and personality style, report findings that are promising for future research aimed at better delineating AVPD and informing treatment.

    Full Text Available Abstract Background The aim of this study was to evaluate the prevalence of signs and symptoms of temporomandibular disorders (TMD and oral parafunction habits among Saudi adolescents in the permanent dentition stage. Methods A total of 385 (230 females and 155 males school children age 12–16, completed a questionnaire and were examined clinically. A stratified selection technique was used for schools allocation. Results The results showed that 21.3% of the subjects exhibited at least one sign of TMD and females were generally more affected than males. Joint sounds were the most prevalent sign (13.5% followed by restricted opening (4.7% and opening deviation (3.9%. The amplitude of mouth opening, overbite taken into consideration, was 46.5 mm and 50.2 mm in females and males respectively. TMJ pain and muscle tenderness were rare (0.5%. Reported symptoms were 33%, headache being the most frequent symptom 22%, followed by pain during chewing 14% and hearing TMJ noises 8.7%. Difficulty during jaw opening and jaw locking were rare. Lip/cheek biting was the most common parafunction habit (41% with females significantly more than males, followed by nail biting (29%. Bruxism and thumb sucking were only 7.4% and 7.8% respectively. Conclusion The prevalence of TMD signs were 21.3% with joint sounds being the most prevalent sign. While TMD symptoms were found to be 33% as, with headache being the most prevalent. Among the oral parafunctions, lip/cheek biting was the most prevalent 41% followed by nail biting 29%.

    Background Preclinical trials are essential to test efficacious options to substitute the temporomandibular joint (TMJ) disk. The contemporary absence of an ideal treatment for patients with severe TMJ disorders can be related to difficulties concerning the appropriate study design to conduct preclinical trials in the TMJ field. These difficulties can be associated with the use of heterogeneous animal models, the use of the contralateral TMJ as control, the absence of rigorous randomized controlled preclinical trials with blinded outcomes assessors, and difficulties involving multidisciplinary teams. Objective This study aims to develop a new, reproducible, and effective study design for preclinical research in the TMJ domain, obtaining rigorous data related to (1) identify the impact of bilateral discectomy in black Merino sheep, (2) identify the impact of bilateral discopexy in black Merino sheep, and (3) identify the impact of three different bioengineering TMJ discs in black Merino sheep. Methods A two-phase exploratory randomized controlled preclinical trial with blinded outcomes is proposed. In the first phase, nine sheep are randomized into three different surgical bilateral procedures: bilateral discectomy, bilateral discopexy, and sham surgery. In the second phase, nine sheep are randomized to bilaterally test three different TMJ bioengineering disk implants. The primary outcome is the histological gradation of TMJ. Secondary outcomes are imaging changes, absolute masticatory time, ruminant time per cycle, ruminant kinetics, ruminant area, and sheep weight. Results Previous preclinical studies in this field have used the contralateral unoperated side as a control, different animal models ranging from mice to a canine model, with nonrandomized, nonblinded and uncontrolled study designs and limited outcomes measures. The main goal of this exploratory preclinical protocol is to set a new standard for future preclinical trials in oromaxillofacial surgery

    2013-11-01

    Autism spectrum disorders are neurodevelopmental disorders characterized by deficits in social interactions, communication, and repetitive or restricted interests. There is strong evidence that de novo or inherited genetic alterations play a critical role in causing Autism Spectrum Disorders, but non-genetic causes, such as in utero infections, may also play a role. Magnetic resonance imaging based and autopsy studies indicate that early rapid increase in brain size during infancy could underlie the deficits in a large subset of subjects. Clinical studies show benefits for both behavioral and pharmacological treatment strategies. Genotype-specific treatments have the potential for improving outcome in the future.

    The phenomenology of dissociative disorders may be complex and sometimes confusing. We describe here two cases who were initially misdiagnosed. The first case concerned a 61 year-old woman, who was initially diagnosed as an isolated dissociative fugue and was actually suffering from severe major depressive episode. The second case concerned a 55 year-old man, who was suffering from type I bipolar disorder and polyvascular disease, and was initially diagnosed as dissociative fugue in a mooddestabilization context, while it was finally a stroke. Yet dissociative disorders as affective disorder comorbidity are relatively unknown. We made a review on this topic. Dissociative disorders are often studied through psycho-trauma issues. Litterature is rare on affective illness comorbid with dissociative disorders, but highlight the link between bipolar and dissociative disorders. The later comorbidity often refers to an early onset subtype with also comorbid panic and depersonalization-derealization disorder. Besides, unipolar patients suffering from dissociative symptoms have more often cyclothymic affective temperament. Despite the limits of such studies dissociative symptoms-BD association seems to correspond to a clinical reality and further works on this topic may be warranted. Copyright © 2014 L’Encéphale.

    2017-12-01

    Although meetings are central to organizational work, considerable time devoted to meetings in Academic Health Centers appears to be unproductively spent. The primary purposes of this article are to delineate and describe Meeting Disorders, pathological processes resulting in these inefficient and ineffective scenarios, and Meeting Fatigue Disorder (MFD), a clinical syndrome. The paper also offers preliminary approaches to remedies. The authors integrate observations made during tens of thousands of hours in administrative meetings in academic medical settings with information in the literature regarding the nature, causes and potential interventions for dysfunctional groups and meetings. Meeting Disorders, resulting from distinct pathologies of leadership and organization, constitute prevalent subgroups of the bureaucrapathologies, pathological conditions caused by dysfunctional bureaucratic processes that generate excesses of wasted time, effort, and other resources. These disorders also generate frustration and demoralization among participants, contributing to professional burnout. Meeting Fatigue Disorder (MFD) is a subjective condition that develops in individuals who overdose on these experiences and may reflect one manifestation of burnout. Meeting disorders and Meeting Fatigue Disorder occur commonly in bureaucratic life. Resources and potential remedies are available to help ameliorate their more deleterious effects.

  1. Difference or disorder? Cultural issues in understanding neurodevelopmental disorders.

    2013-01-01

    Developmental disorders, such as autism spectrum disorder and specific language impairment, are biologically based disorders that currently rely on behaviorally defined criteria for diagnosis and treatment. Specific behaviors that are included in diagnostic frameworks and the point at which individual differences in behavior constitute abnormality are largely arbitrary decisions. Such decisions are therefore likely to be strongly influenced by cultural values and expectations. This is evident in the dramatically different prevalence rates of autism spectrum disorder across countries and across different ethnic groups within the same country. In this article, we critically evaluate the understanding of developmental disorders from a cultural perspective. We specifically consider the challenges of applying diagnostic methods across cultural contexts, the influence of cultural values and expectations on the identification and treatment of children with suspected disorders, and how cross-cultural studies can help to refine cognitive theories of disorder that have been derived exclusively from Western North American and European investigations. Our review synthesizes clinical, cultural, and theoretical work in this area, highlighting potential universals of disorder and concluding with recommendations for future research and practice.

    Post-traumatic stress disorder is highly prevalent among individuals who suffer from opioid use disorder. Compared to individuals with opioid use disorder alone, those with post-traumatic stress disorder have a worse course of illness, occupational functioning, and physical health. The neurobiological pathways underlying each disorder overlap substantially, and there are multiple pathways through which these disorders may interact. This narrative review explores evidence underpinning 3 explanatory perspectives on comorbid post-traumatic stress disorder and opioid use disorder: The opioid susceptibility model (a.k.a.: the Self-Medication Hypothesis), the post-traumatic stress disorder susceptibility model, and the common factors model. Diagnostic implications, treatment implications, and directions for future research are discussed.

    This article presents an up-to-date summary of the genetic etiology, diagnostic criteria, clinical features, and current management recommendations for the most common neurocutaneous disorders encountered in clinical adult and pediatric neurology practices. The phakomatoses are a phenotypically and genetically diverse group of multisystem disorders that primarily affect the skin and central nervous system. A greater understanding of the genetic and biological underpinnings of numerous neurocutaneous disorders has led to better clinical characterization, more refined diagnostic criteria, and improved treatments in neurofibromatosis type 1, Legius syndrome, neurofibromatosis type 2, Noonan syndrome with multiple lentigines, tuberous sclerosis complex, Sturge-Weber syndrome, and incontinentia pigmenti. Neurologists require a basic knowledge of and familiarity with a wide variety of neurocutaneous disorders because of the frequent involvement of the central and peripheral nervous systems. A simple routine skin examination can often open a broad differential diagnosis and lead to improved patient care.

    To determine the risk of future childhood psychiatric disorders in celiac disease, assess the association between previous psychiatric disorders and celiac disease in children, and investigate the risk of childhood psychiatric disorders in siblings of celiac disease probands. This was a nationwide registry-based matched cohort study in Sweden with 10 903 children (aged celiac disease and 12 710 of their siblings. We assessed the risk of childhood psychiatric disorders (any psychiatric disorder, psychotic disorder, mood disorder, anxiety disorder, eating disorder, psychoactive substance misuse, behavioral disorder, attention-deficit hyperactivity disorder [ADHD], autism spectrum disorder [ASD], and intellectual disability). HRs of future psychiatric disorders in children with celiac disease and their siblings was estimated by Cox regression. The association between previous diagnosis of a psychiatric disorder and current celiac disease was assessed using logistic regression. Compared with the general population, children with celiac disease had a 1.4-fold greater risk of future psychiatric disorders. Childhood celiac disease was identified as a risk factor for mood disorders, anxiety disorders, eating disorders, behavioral disorders, ADHD, ASD, and intellectual disability. In addition, a previous diagnosis of a mood, eating, or behavioral disorder was more common before the diagnosis of celiac disease. In contrast, siblings of celiac disease probands were at no increased risk of any of the investigated psychiatric disorders. Children with celiac disease are at increased risk for most psychiatric disorders, apparently owing to the biological and/or psychological effects of celiac disease. Copyright © 2017 Elsevier Inc.

    Full Text Available BACKGROUND AND AIM: The aim of this study was to assess the association between the clinical and cone-beam computed tomography (CBCT findings in relation to bony changes in patients with temporomandibular disorders (TMD. METHODS: According to the research diagnostic criteria for temporomandibular disorder (RDC/TMD, forty-one patients with type II TMD (42 TM joints and type III TMD (40 TM joints were recruited for this study. Condylar position and bony changes including flattening, sclerosis, osteophytes, resorption, and erosion of joint were evaluated by CBCT and compared with clinical findings. Data were analyzed by SPSS software. RESULTS: Condylar flattening, sclerosis, resorption, and erosion were not significantly associated with joint/masticatory muscles pain or crepitus sound. The vertical or horizontal position of the condyle showed no significant relationship with the clinical findings. Condylar osteophyte was significantly associated with pain in masticatory muscles and crepitus (P = 0.030 and P = 0.010, respectively. There was no association between the condylar range of motion and pain in joint or masticatory muscles. CONCLUSION: Condylar osteophyte was significantly associated with both masticatory muscles pain and crepitus sound. No significant relationship was found between the other temporomandibular joint (TMJ radiographic and clinical findings in patients with TMD.

    The aim of the study was to investigate the routine, sleep history, and orofacial disorders associated with children aged 3-7 years with nocturnal bruxism. Children (n = 66) were divided into groups of parent reported nocturnal bruxism (n = 34) and those without the disorder (n = 32). Data about the child's routine during the day, during sleep and awakening, headache frequency, temporomandibular joint (TMJ), and hearing impairments were obtained through interviews with parents/caregivers. Electromyography examination was used to assess the activity of facial muscles. Multiple logistic regression (MLR), chi-square test, and t-test analyses were performed. MLR revealed association of nightmares (p = 0.002; OR = 18.09) and snoring (p = 0.013; OR = 0.14) with bruxism. Variables related to awakening revealed an association with bruxism (p bruxism) reported more complaints of orofacial pain, facial appearance, and headache occurrence (p  0.05). Nightmares and snoring are associated with nocturnal bruxism in children. Bruxism in children elicits consequences such as headache, orofacial pain, and pain related to awakening.

    Full Text Available Abstract Introduction: The instrumental practice for a long time, the high performance level, the strict technique and the specific shape of each musical instrument can take musicians to overcome their physiological limits, giving a high prevalence of musculoskeletal injuries. Objective: Investigate the prevalence of temporomandibular joint disorder and neck pain in musicians. Methods: Between August and September 2015 were reviewed five databases: LILACS, SciELO, Medline / PubMed, Scopus and Web of Science. The articles were read and evaluated by the criteria of the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE, items, that obtained a percentage above of 50 percent, were considered in the analysis of this work. Results: 15 articles attended the inclusion criteria. Among all musicians the prevalence of TMJ pain ranged from 10 - 81% and the prevalence of neck pain ranged from 29 - 80%. Conclusion: In this study was observed that the musicians showed both, temporomandibular joint disorders and neck pain, watching a high prevalence especially in violinists and the horn players. In the risk factors identified in the literature for the emergence of painful symptoms in musicians, stand out the biomechanical factors involved in maintaining anti-physiologic postures.

    Full Text Available Introduction. Some clinicians believed that mandibular deviation leads to facial asymmetry and it also had a correlation with temporomandibular disorders (TMDs. Posteroanterior (PA cephalogram was widely reported as a regular record in treating facial asymmetry and craniofacial anomalies. The objective of this study was to analyze the relationship of menton deviation in PA cephalogram with temporomandibular disorders (TMDs symptoms. Materials and Methods. TMJ function was initially screened based on TMD-DI questionnaire. PA cephalogram of volunteer subjects with TMDs (n=37 and without TMDs (n=33 with mean age of 21.61±2.08 years was taken. The menton deviation was measured by the distance (mm from menton point to midsagittal reference (MSR horizontally, using software digitized measurement, and categorized as asymmetric if the value is greater than 3 mm. The prevalence and difference of menton deviation in both groups were evaluated by unpaired t-test. Result. The prevalence of symmetry group showed that 65.9% had no TMDs with mean of 1,815 ± 0,71 mm; in contrast, the prevalence of asymmetry group showed that 95.5% reported TMDs with mean of 3,159 ± 1,053 mm. There was a significant difference of menton deviation to TMDs (p=0.000 in subjects with and without TMDs. Conclusion. There was a significant relationship of menton deviation in PA cephalogram with TMDs based on TMD-DI index.

    A safe and effective way to control weight in patients with affective disorders is needed, and phentermine is a possible candidate. We performed a PubMed search of articles pertaining to phentermine, sibutramine, and affective disorders. We compared the studies of phentermine with those of sibutramine. The search yielded a small number of reports. Reports concerning phentermine and affective disorders reported that i) its potency in the central nervous system may be comparatively low, and ii) it may induce depression in some patients. We were unable to find more studies on the subject; thus, it is unclear presently whether phentermine use is safe in affective disorder patients. Reports regarding the association of sibutramine and affective disorders were slightly more abundant. A recent study that suggested that sibutramine may have deleterious effects in patients with a psychiatric history may provide a clue for future phentermine research. Three explanations are possible concerning the association between phentermine and affective disorders: i) phentermine, like sibutramine, may have a depression-inducing effect that affects a specific subgroup of patients, ii) phentermine may have a dose-dependent depression-inducing effect, or iii) phentermine may simply not be associated with depression. Large-scale studies with affective disorder patients focusing on these questions are needed to clarify this matter before investigation of its efficacy may be carried out and it can be used in patients with affective disorders.

    Bipolar disorder is a recurrent disorder that affects more than 1% of the world population and usually has its onset during youth. Its chronic course is associated with high rates of morbidity and mortality, making bipolar disorder one of the main causes of disability among young and working-age people. The implementation of early intervention strategies may help to change the outcome of the illness and avert potentially irreversible harm to patients with bipolar disorder, as early phases may be more responsive to treatment and may need less aggressive therapies. Early intervention in bipolar disorder is gaining momentum. Current evidence emerging from longitudinal studies indicates that parental early-onset bipolar disorder is the most consistent risk factor for bipolar disorder. Longitudinal studies also indicate that a full-blown manic episode is often preceded by a variety of prodromal symptoms, particularly subsyndromal manic symptoms, therefore supporting the existence of an at-risk state in bipolar disorder that could be targeted through early intervention. There are also identifiable risk factors that influence the course of bipolar disorder, some of them potentially modifiable. Valid biomarkers or diagnosis tools to help clinicians identify individuals at high risk of conversion to bipolar disorder are still lacking, although there are some promising early results. Pending more solid evidence on the best treatment strategy in early phases of bipolar disorder, physicians should carefully weigh the risks and benefits of each intervention. Further studies will provide the evidence needed to finish shaping the concept of early intervention.

    Full Text Available Paulina Zelviene, Evaldas Kazlauskas Department of Clinical and Organizational Psychology, Vilnius University, Vilnius, Lithuania Abstract: Adjustment disorder (AjD is among the most often diagnosed mental disorders in clinical practice. This paper reviews current status of AjD research and discusses scientific and clinical issues associated with AjD. AjD has been included in diagnostic classifications for over 50 years. Still, the diagnostic criteria for AjD remain vague and cause difficulties to mental health professionals. Controversies in definition resulted in the lack of reliable and valid measures of AjD. Epidemiological data on prevalence of AjD is scarce and not reliable because prevalence data are biased by the diagnostic algorithm, which is usually developed for each study, as no established diagnostic standards for AjD are available. Considerable changes in the field of AjD could follow after the release of the 11th edition of International Classification of Diseases (ICD-11. A new AjD symptom profile was introduced in ICD-11 with 2 main symptoms as follows: 1 preoccupation and 2 failure to adapt. However, differences between the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition and ICD-11 AjD diagnostic criteria could result in diverse research findings in the future. The best treatment approach for AjD remains unclear, and further treatment studies are needed to provide AjD treatment guidelines to clinicians.

    Two science-arts approaches are emerging as effective means to convey "futurethinking" to learners: systems gaming and experiential futures. FutureCoast exemplifies the latter: by engaging participants with voicemails supposedly leaking from the cloud of possible futures, the storymaking game frames the complexities of climate science in relatable contexts. Because participants make the voicemails themselves, FutureCoast opens up creative ways for people to think about possibly climate-changed futures and personal ways to talk about them. FutureCoast is a project of the PoLAR Partnership with a target audience of informal adult learners primarily reached via mobile devices and online platforms. Scientists increasingly use scenarios and storylines as ways to explore the implications of environmental change and societal choices. Stories help people make connections across experiences and disciplines and link large-scale events to personal consequences. By making the future seem real today, FutureCoast's framework helps people visualize and plan for future climate changes. The voicemails contributed to FutureCoast are spread through the game's intended timeframe (2020 through 2065). Based on initial content analysis of voicemail text, common themes include ecosystems and landscapes, weather, technology, societal issues, governance and policy. Other issues somewhat less frequently discussed include security, food, industry and business, health, energy, infrastructure, water, economy, and migration. Further voicemail analysis is examining: temporal dimensions (salient time frames, short vs. long term issues, intergenerational, etc.), content (adaptation vs. mitigation, challenges vs. opportunities, etc.), and emotion (hopeful, resigned, etc. and overall emotional context). FutureCoast also engaged audiences through facilitated in-person experiences, geocaching events, and social media (Tumblr, Twitter, Facebook, YouTube). Analysis of the project suggests story

    Functional esophageal disorders consist of a disease category that present with esophageal symptoms (heartburn, chest pain, dysphagia, globus) not explained by mechanical obstruction (stricture, tumor, eosinophilic esophagitis), major motor disorders (achalasia, EGJ outflow obstruction, absent contractility, distal esophageal spasm, jackhammer esophagus), or gastroesophageal reflux disease (GERD). While mechanisms responsible are unclear, it is theorized that visceral hypersensitivity and hypervigilance play an important role in symptom generation, in the context of normal or borderline function. Treatments directed at improving borderline motor dysfunction or reducing reflux burden to sub-normal levels have limited success in symptom improvement. In contrast, strategies focused on modulating peripheral triggering and central perception are mechanistically viable and clinically meaningful. However, outcome data from these treatment options are limited. Future research needs to focus on understanding mechanisms underlying visceral hypersensitivity and hypervigilance so that appropriate targets and therapies can be developed.

    Craniomandiublar disorders involving the facial anatomy may be difficult to demonstrate in planar images. Although bone scanning is generally more sensitive than radiography, facial bone anatomy is complex and focal areas of increased or decreased radiotracer may become obscured by overlapping structures in planar images. Thus SPECT appears ideally suited to examination of the facial skeleton. A series of patients with craniomandibular disorders of unknown origin were imaged using 20 mCi Tc-99m MDP. Planar and SPECT (Siemens 7500 ZLC Orbiter) images were obtained four hours after injection. The SPECT images were reconstructed with a filtered back-projection algorithm. In order to improve image contrast and resolution in SPECT images, the rotation views were pre-processed with a Bayesean deblurring algorithm which has previously been show to offer improved contrast and resolution in planar images. SPECT images using the pre-processed rotation views were obtained and compared to the SPECT images without pre-processing and the planar images. TMJ arthropathy involving either the glenoid fossa or the mandibular condyle, orthopedic changes involving the mandible or maxilla, localized dental pathosis, as well as changes in structures peripheral to the facial skeleton were identified. Bayesean pre-processed SPECT depicted the facial skeleton more clearly as well as providing a more obvious demonstration of the bony changes associated with craniomandibular disorders than either planar images or SPECT without pre-processing

    Primary tic disorders are complex, multifactorial disorders in which tics are accompanied by other sensory features and an array of comorbid behavioral disorders. Secondary tics are proportionally much less frequent, but their etiology is diverse. This review aims to guide clinicians in the recognition of the phenomenology, pathophysiology, and treatment of these disorders. Advances include greater phenomenologic insights, particularly of nonmotor (sensory) features; increased knowledge of disease mechanisms, particularly coming from neuropsychological, functional imaging, pathologic, and animal model studies; growing evidence on the efficacy of alpha-2 agonists and the newer generation of dopamine-modulating agents; and recent strides in the evaluation of cognitive-behavioral therapy and deep brain stimulation surgery. The correct diagnostic approach to tic disorders requires accurate historical gathering, a thorough neurologic examination, and detailed definition of the patient's psychopathologic profile. Treatment should always begin with individualized psychoeducational strategies. Although pharmacologic treatments remain beneficial for most patients, cognitive-behavioral treatments have thus far shown promising efficacy. Deep brain stimulation surgery should still be limited to adult patients refractory to pharmacotherapy and cognitive-behavioral therapy.

    Avoidant personality disorder (AVPD) is a relatively common disorder that is associated with significant distress, impairment, and disability. It is a chronic disorder with an early age at onset and a lifelong impact. Yet it is underrecognized and poorly studied. Little is known regarding the most effective treatment. The impetus for research into this condition has waxed and waned, possibly due to concerns regarding its distinctiveness from other disorders, especially social anxiety disorder (SAD), schizoid personality disorder, and dependent personality disorder. The prevailing paradigm subscribes to the "severity continuum hypothesis", in which AVPD is viewed essentially as a severe variant of SAD. However, areas of discontinuity have been described, and there is support for retaining AVPD as a distinct diagnostic category. Recent research has focused on the phenomenology of AVPD, factors of possible etiological significance such as early parenting experiences, attachment style, temperament, and cognitive processing. Self-concept, avoidant behavior, early attachments, and attachment style may represent points of difference from SAD that also have relevance to treatment. Additional areas of research not focused specifically on AVPD, including the literature on social cognition as it relates to attachment and personality style, report findings that are promising for future research aimed at better delineating AVPD and informing treatment.

    This thesis describes the measurement of brain-tissue functions in patients with movement disorders using positron emission tomography (PET). This scanning technique is a method for direct in vivo quantitation of the regional tissue content of positron emitting radionuclides in brain (or other organs) in an essentially non-invasive way. Ch. 2 outlines some general features of PET and describes the scanner which has been used for the studies in this thesis. Also the tracer methodology, as applied to data investigations of movement disorders, are discussed. Ch. 3 contains the results of the PET investigations which were performed in the study of movement disorders. The results are presented in the form of 12 papers. The main goals of these studies were the understanding of the pathophysiology of Parkinson's disease, Huntington's chorea, Steele-Richardson-Olzewski syndrome and special case reports. Ch. 4 summarizes the results of these publications and Ch. 5 concludes the main part of this thesis with a general discussion of movement disorders in relation to PET investigations. 697 refs.; 60 figs.; 31 tabs

    2016-01-01

    This report defines criteria and reviews the epidemiology, pathophysiology, and management of the following common anorectal disorders: fecal incontinence (FI), functional anorectal pain, and functional defecation disorders. FI is defined as the recurrent uncontrolled passage of fecal material for at least 3 months. The clinical features of FI are useful for guiding diagnostic testing and therapy. Anorectal manometry and imaging are useful for evaluating anal and pelvic floor structure and function. Education, antidiarrheals, and biofeedback therapy are the mainstay of management; surgery may be useful in refractory cases. Functional anorectal pain syndromes are defined by clinical features and categorized into 3 subtypes. In proctalgia fugax, the pain is typically fleeting and lasts for seconds to minutes. In levator ani syndrome and unspecified anorectal pain, the pain lasts more than 30 minutes, but in levator ani syndrome there is puborectalis tenderness. Functional defecation disorders are defined by ≥2 symptoms of chronic constipation or irritable bowel syndrome with constipation, and with ≥2 features of impaired evacuation, that is, abnormal evacuation pattern on manometry, abnormal balloon expulsion test, or impaired rectal evacuation by imaging. It includes 2 subtypes: dyssynergic defecation and inadequate defecatory propulsion. Pelvic floor biofeedback therapy is effective for treating levator ani syndrome and defecatory disorders.

    Full Text Available Eating disorders are considered chronic diseases of civilization. The most studied and well known are anorexia and bulimia nervosa. Anorexia is considered one of the most common psychiatric problems of girls in puberty and adolescence. Due to high mortality and morbidity as well as the increasing expansion of these diseases, it is clear why the amount of research on these diseases is growing worldwide. Eating disorders lead to numerous medical complications, mostly due to late diagnosis. The main characteristic of these diseases is changed behavior in the nutrition, either as an intentional restriction of food, i.e. extreme dieting, or overeating, i.e. binge eating. Extreme dieting, skipping meals, self-induced vomiting, excessive exercise, and misuse of laxatives and diuretics for the purpose of maintaining or reducing body weight are characteristic forms of compensatory behavior of patients with eating disorder. The most appropriate course of treatment is determined by evaluating the patient’s health condition, associated with behavior and eating habits, the experience of one’s own body, character traits of personality, and consequently the development and functioning of the individual. The final treatment plan is individual. Eating disorders are a growing medical problem even in this part of the world. Prevention should be planned in cooperation with different sectors so as to stop the epidemic of these diseases.

    Although the relationship between dreaming and psychopathology has been studied quite extensively, research on dreaming in patients with personality disorders has been very scarce. In patients with borderline personality disorder, negatively toned dreams and heightened nightmare frequency have been found-characteristics not determined by co-morbid depression or posttraumatic stress disorder. The review includes suggestions for future studies as the existing results clearly indicate that this line of research is most interesting. Lastly, clinical recommendations especially regarding the treatment of the often found co-morbid nightmare disorder will be given.

    Full Text Available The comorbidity of bipolar disorder and anxiety disorders is a well known concept. Obsessive-compulsive disorder is the most commonly seen comorbid anxiety disorder in bipolar patients. Some genetic variants, neurotransmitters especially serotonergic systems and second-messenger systems are thought to be responsible for its etiology. Bipolar disorder alters the clinical aspects of obsessive compulsive disorder and is associated with poorer outcome. The determination of comorbidity between bipolar disorder and obsessive compulsive disorder is quite important for appropriate clinical management and treatment.

    Sleep disorders have a profound and well-documented impact on overall health and quality of life in the general population. In patients with chronic disease, sleep disorders are more prevalent, with an additional morbidity and mortality burden. The complex and dynamic relationship between sleep disorders and chronic kidney disease (CKD) remain relatively little investigated. This article presents an overview of sleep disorders in patients with CKD, with emphasis on relevant pathophysiologic underpinnings and clinical presentations. Evidence-based interventions will be discussed, in the context of individual sleep disorders, namely sleep apnea, insomnia, restless leg syndrome and excessive daytime sleepiness. Limitations of the current knowledge as well as future research directions will be highlighted, with a final discussion of different conceptual frameworks of the relationship between sleep disorders and CKD.

    Raine, Adrian

    2018-05-07

    Although antisocial personality disorder (APD) is one of the most researched personality disorders, it is still surprisingly resistant to treatment. This lack of clinical progress may be partly due to the failure to view APD as a neurodevelopmental disorder and to consider early interventions. After first defining what constitutes a neurodevelopmental disorder, this review evaluates the extent to which APD meets neurodevelopmental criteria, covering structural and functional brain imaging, neurocognition, genetics and epigenetics, neurochemistry, and early health risk factors. Prevention and intervention strategies for APD are then outlined, focusing on addressing early biological and health systems, followed by forensic and clinical implications. It is argued both that APD meets criteria for consideration as a neurodevelopmental disorder and that consideration should be given both to the possibility that early onset conduct disorder is neurodevelopmental in nature, and also to the inclusion of psychopathy as a specifier in future Diagnostic and Statistical Manual revisions of APD.

    Full Text Available PurposeWhiplash injury can cause internal derangement of the temporomandibular joint (TMJ and lead to temporomandibular disorders (TMDs. Our aim was to evaluate whether the initial clinical findings in TMD patients with whiplash injury are correlated with their magnetic resonance imaging (MRI characteristics.Materials and methodsThis case–control study involved 219 patients (135 women, 84 men; mean age: 37.84 years who visited our orofacial pain clinic with TMD; TMD was diagnosed using the diagnostic criteria for TMD Axis I. Patients were categorized into three groups based on the presence and type of macrotrauma: in the “wTMD” group, patients had suffered whiplash injury; patients in the “pTMD” group had post-traumatic TMD; the “iTMD” group comprised patients who had presented with TMD symptoms and had sustained no macrotrauma. We investigated the presence of disk displacement, effusion, disk deformity, and condylar degeneration, and changes in the lateral pterygoid muscle (LPM. To evaluate the severity of TMD pain and objectively analyze symptoms, we used a visual analog scale (VAS, palpation index (PI, neck PI, dysfunction index, and craniomandibular index (CMI.ResultsThe VAS scores, and the severity indexes of the TMD including PI, neck PI, and CMI were highest in the wTMD patients. Atrophy of the LPM was most commonly seen in the wTMD group, as was disk deformity. In wTMD patients only, VAS score was significantly correlated with stress; it was correlated with headache in wTMD and iTMD patients. The clinical symptoms of TMD were not correlated with MRI findings in the wTMD group. However, alterations in the LPM were strongly correlated with disk displacement.ConclusionIf clinicians recognize alterations in the LPM and disk displacement in the TMJ, they will better understand the clinical symptoms and pathophysiology of TMD with whiplash injury. Whiplash injury may lead to TMD via different mechanisms from other macrotraumas.

    2013-02-06

    To investigate the associations of aural symptoms, headache and depression with the presence of temporomandibular disorder (TMD) symptoms in a young adult population in Japan. A personal interview survey was conducted on first-year university students (n = 1,930) regarding symptoms of TMD, aural problems, headache, shoulder pain and depression. Logistic regression was applied to assess the associations of these problems with the presence of TMD symptoms after controlling for age and gender. Among the 1,930 students, 543 students exhibited TMD symptoms and were classified into 7 groups: clicking only (Group I, n = 319), pain in the TMJ only (Group II, n = 21), difficulty in mouth opening only (Group III, n = 18), clicking and pain (Group IV, n = 29), clicking and difficulty in mouth opening (Group V, n = 48), difficulty in mouth opening and pain (Group VI, n = 11), and combination of three symptoms (Group VII, n = 97). The control group (n = 1,387) were subjects without any TMD symptoms. After adjusting for age and gender, a strong association was observed between TMD symptoms (Group II and IV) and tinnitus (OR = 12.1 and 13.2, respectively). TMD symptoms (Group I, II and III) were also associated with vertigo and headache. Otalgia and depression were significantly associated with the presence of clicking only. TMD symptoms were significantly correlated to aural symptoms and headache. A functional evaluation of the stomatognathic system should be considered in subjects with unexplained aural symptoms and headache.

    Attention-deficit/hyperactivity disorder (ADHD) is a highly prevalent disorder with significant functional impairment. ADHD is frequently complicated by oppositional symptoms, which are difficult to separate from comorbidity with oppositional defiant disorder, conduct disorder, and aggressive symptoms. This review addresses the impact of oppositional symptoms on ADHD, disease course, functional impairment, clinical management, and treatment response. Oppositional defiant disorder or conduct disorder may be comorbid in more than half of ADHD cases and are more common with the combined than with the inattentive ADHD subtype. Comorbid symptoms of oppositional defiant disorder and conduct disorder in patients with ADHD can have a significant impact on the course and prognosis for these patients and may lead to differential treatment response to both behavioral and pharmacologic treatments. Assessment of oppositional symptoms is an essential part of ADHD screening and diagnosis and should include parental, as well as educator, input. Although clinical evidence remains limited, some stimulant and nonstimulant medications have shown effectiveness in treating both core ADHD symptoms and oppositional symptoms. Oppositional symptoms are a key consideration in ADHD management, although the optimum approach to treating ADHD complicated by such symptoms remains unclear. Future research should focus on the efficacy and safety of various behavioral and medication regimens, as well as longitudinal studies to further clarify the relationships between ADHD, oppositional defiant disorder, and conduct disorder.

    To systematically review evidence concerning disordered eating practices in dietary-controlled gastrointestinal conditions. Three key questions were examined: a) are disordered eating practices a feature of GI disorders?; b) what abnormal eating practices are present in those with GI disorders?; and c) what factors are associated with the presence of disordered eating in those with GI disorders? By exploring these questions, we aim to develop a conceptual model of disordered eating development in GI disease. Five key databases, Web of Science with Conference Proceedings (1900-2014) and MEDLINE (1950-2014), PubMed, PsycINFO (1967-2014) and Google Scholar, were searched for papers relating to disordered eating practices in those with GI disorders. All papers were quality assessed before being included in the review. Nine papers were included in the review. The majority of papers reported that the prevalence of disordered eating behaviours is greater in populations with GI disorders than in populations of healthy controls. Disordered eating patterns in dietary-controlled GI disorders may be associated with both anxiety and GI symptoms. Evidence concerning the correlates of disordered eating was limited. The presence of disordered eating behaviours is greater in populations with GI disorders than in populations of healthy controls, but the direction of the relationship is not clear. Implications for further research are discussed. Copyright © 2014 Elsevier Ltd. All rights reserved.

  3. Social Anxiety Disorder and Mood Disorders Comorbidity

    Full Text Available Social Anxiety Disorder is a common disorder leading functional impairment. The comorbidity between mood disorders with social anxiety disorder is relatively common. This comorbidity impacts the clinical severity, resistance and functionality of patients. The systematic evaluation of the comorbidity in both patient groups should not be ignored and be carefully conducted. In general, social anxiety disorder starts at an earlier age than mood disorders and is reported to be predictor for subsequent major depression. The absence of comorbidity in patients with social anxiety disorder is a predictor of good response to treatment. In bipolar disorder patients with comorbid social anxiety disorder, there is an increased level of general psychopathology. Besides, they have poor outcome and increased risk of suicide. In this article, comorbidity between these two disorders has been evaluated in detail.

    Migraine with and without aura (MA and MO, respectively) have a strong genetic basis. Different approaches using linkage-, candidate gene- and genome-wide association studies have been explored, yielding limited results. This may indicate that the genetic component in migraine is due to rare...... variants; capturing these will require more detailed sequencing in order to be discovered. Next-generation sequencing (NGS) techniques such as whole exome and whole genome sequencing have been successful in finding genes in especially monogenic disorders. As the molecular genetics research progresses......, the technology will follow, rendering these approaches more applicable in the search for causative migraine genes in MO and MA. To date, no studies using NGS in migraine genetics have been published. In order to gain insight into the future possibilities of migraine genetics, we have looked at NGS studies...

    Our life develops as the anticipation of future. Everything we wish, hope, plan and carry out and think is or should be related to future and will have its effects in future. The certainty may spread that it is a necessary obligation to learn to find out our actual being more clearly to be able to develop a thinking and acting that is directed to future that has also a total of responsability as its essence. We will later atone for the failed outlooks into future or for only moderate or uncompleted starts of planning. For this reason we should consider that future does not come for its own, not without our demands, not without our acting. Only if our reflection and aspiration, thinking and acting is done with moderate and circumspect sense in the right way it will be a good fundamental for the future. (orig.) [de

    Congenital imprinting disorders (IDs) are characterised by molecular changes affecting imprinted chromosomal regions and genes, i.e. genes that are expressed in a parent-of-origin specific manner. Recent years have seen a great expansion in the range of alterations in regulation, dosage or DNA...... sequence shown to disturb imprinted gene expression, and the correspondingly broad range of resultant clinical syndromes. At the same time, however, it has become clear that this diversity of IDs has common underlying principles, not only in shared molecular mechanisms, but also in interrelated clinical...

  7. The validity of clinical findings for diagnosing temporomandibular disorders in patients from different age and gender groups

    2008-01-01

    This study was to clarify the diagnostic accuracy of clinical findings for internal derangement of the temporomandibular joint (TMJ) compared with that of magnetic resonance imaging. A series of 4559 patients (879 male and 3680 female, mean age 32.7 years; range 8-85 years;) with temporomandibular disorders were clinically examined by un unspecified number of dentists. All patients underwent magnetic resonance imaging (MRI). The clinical findings that characterize disc displacement, anterior disc displacement with reduction (ADDwR) and anterior disc displacement without reduction (ADDwoR) are pain, clicking sound and limitation of maximum mouth opening. These clinical findings were compared to the MRI interpretation, which was used as the gold standard for diagnosis of temporomandibular disorders to define the diagnostic accuracy, specificity, sensitivity, positive predictive value and negative predictive value of clinical findings. The prevalence of clinical finding was 3990 joints (43%) with pain, 2775 joints (30%) with clicking sound and 1731 patients (38%) with limitation of opening. Three thousands forty seven joints were diagnosed as having a normal disc position, 510 joints with sideways disc displacement, 2312 joints with ADDwR, 3239 joints with ADDwoR on MR image. The sensitivity of clinical findings was considerably low: sensitivity was 0.48 for pain versus internal derangement, 0.51 for clicking sound versus ADDwR, 0.62 for limitation of opening versus ADDwoR. The sensitivity was higher in the younger group for clicking sound versus ADDwR, but sensitivity was higher in the older group for limitation of opening versus ADDwoR. The diagnostic accuracy based on clinical findings of internal derangement of TMJ was found to be correlated with age. This study has been that the overall diagnostic accuracy of the clinical findings to determine the status of the joint is about 50-60%. The status of the joint could not be accurately determined by clinical findings

    The eating disorder literature has sought to understand the role of comorbid psychiatric diagnoses and coping in relation to eating disorders. The present research extends these findings by studying the relationships among depression, coping, and the entire continuum of disordered eating behaviors, with an emphasis on subthreshold eating disorders. 109 undergraduate females completed questionnaires to assess disordered eating symptoms, depressive symptoms, and the use of active and avoidant coping mechanisms. Hypotheses were tested using bivariate linear regression and multivariate linear regression. Results indicated that depression was a significant predictor of disordered eating symptoms after controlling for relationships between depression and coping. Although avoidant coping was positively associated with disordered eating, it was not a significant predictor after controlling for depression and coping. Previous research has found associations between depression and diagnosable eating disorders, and this research extends those findings to the entire continuum of disordered eating. Future research should continue to investigate the predictors and correlates of the disordered eating continuum using more diverse samples. Testing for mediation and moderation among these variables may also be a fruitful area of investigation. Published by Elsevier Ltd.

    There has been a considerable amount of scholarly attention to the relationship between neighborhood effects and conduct disorder, particularly in recent years. Having said this, it has been nearly two decades since a comprehensive synthesis of this literature has been conducted. Relying on a detailed and comprehensive search strategy and inclusion criteria, this article offers a systematic and interdisciplinary review of 47 empirical studies that have examined neighborhood effects and conduct disorder. Described results suggest that there are generally robust linkages between adverse neighborhood factors and conduct disorder and externalizing behavior problems, as 67 of the 93 (72.04%) effect sizes derived from these studies yielded statistically significant neighborhood effects. The review also identifies salient mediating and moderating influences. It discusses study limitations and directions for future research as well.

    Full Text Available Neuroimaging has been used in antisocial personality disorder since the invention of computed tomography and new modalities are introduced as technology advances. Magnetic resonance imaging, diffusion tensor imaging, functional magnetic resonance imaging and radionuclide imaging are such techniques that are currently used in neuroimaging. Although neuroimaging is an indispensible tool for psychiatric reseach, its clinical utility is questionable until new modalities become more accessible and regularly used in clinical practice. The aim of this paper is to provide clinicians with an introductory knowledge on neuroimaging in antisocial personality disorder including basic physics principles, current contributions to general understanding of pathophysiology in antisocial personality disorder and possible future applications of neuroimaging.

    Conduct disorder (CD) is a frequently occurring psychiatric disorder characterized by a persistent pattern of aggressive and non-aggressive rule breaking antisocial behaviours that lead to considerable burden for the patients themselves, their family and society. This review paper updates diagnostic and therapeutic approaches to CD in the light of the forthcoming DSM-5 definition. The diagnostic criteria for CD will remain unchanged in DSM-5, but the introduction of a specifier of CD with a callous-unemotional (CU) presentation is new. Linked to this, we discuss the pros and cons of various other ways to subtype aggression/CD symptoms. Existing guidelines for CD are, with few exceptions, already of a relatively older date and emphasize that clinical assessment should be systematic and comprehensive and based on a multi-informant approach. Non-medical psychosocial interventions are recommended as the first option for the treatment of CD. There is a role for medication in the treatment of comorbid syndromes and/or in case of insufficient response to psychosocial interventions and severe and dangerous aggressive and violent behaviours.

    The relationship of Narcissistic Personality Disorder (NPD) to suicidal behavior is understudied. The modest body of existing research suggests that NPD is protective against low-lethality suicide attempts, but is associated with high lethality attempts. Mood-disordered patients (N = 657) received structured interviews including Axis I and II diagnosis and standardized clinical measures. Following chi-square and t-tests, a logistical regression model was constructed to identify predictors of suicide attempt. While there was no bivariate relationship of NPD on suicide attempt, in the logistic regression patients with NPD were 2.4 times less likely to make a suicide attempt (OR = 0.41; 95% CI = 0.19 - 0.88; p disorder, and to have high aggression and hostility scores. Limitations include that the sample consists of only mood-disordered patients, a modest sample size of NPD, and the data are cross-sectional. The multivariate protective effect of NPD on suicide attempt is consistent with most previous research. The lower impulsivity of NPD patients and less severe personality pathology relative to other personality disorders may contribute to this effect. No relationship of NPD to attempt lethality was found, contradicting other research, but perhaps reflecting differences between study samples. Future studies should oversample NPD patients and include suicide death as an outcome. Clinical implications include discussion of individualized suicide risk assessment with NPD patients.

However, traditional life cycle assessment methodology must be adjusted for the prospective and change-oriented purposes, but no standardised way of doing this has emerged yet.

    Full Text Available Oxytocin is a neuropeptide that plays critical role in mother-infant bonding, pair bonding and prosocial behaviors. Several neuropsychiatric disorders such as autism, schizophrenia, affective disorders, anxiety disorders, attention deficit/hyperactivity disorder, alcohol/substance addiction, aggression, suicide, eating disorders and personality disorders show abnormalities of oxytocin system. These findings have given rise to the studies searching therapeutic use of oxytocin for psychi-atric disorders. The studies of oxytocin interventions in psychiatric disorders yielded potentially promising findings. This paper reviews the role of oxytocin in emotions, behavior and its effects in psychiatric disorders. [Psikiyatride Guncel Yaklasimlar - Current Approaches in Psychiatry 2016; 8(2: 102-113

  17. "Subthreshold" depression: is the distinction between depressive disorder not otherwise specified and adjustment disorder valid?

    Patients with clinically significant symptoms of depression who do not meet the criteria for major depressive disorder or dysthymic disorder are considered to have subthreshold depression. According to DSM-IV, such patients should be diagnosed with depressive disorder not otherwise specified (NOS) if the development of the symptoms is not attributable to a stressful event or with adjustment disorder if the symptoms follow a stressor. Research on the treatment of subthreshold depression rarely addresses the distinction between depressive disorder NOS and adjustment disorder. In the present report from the Rhode Island Methods to Improve Diagnostic Assessment and Services (MIDAS) project, we examined the validity of this distinction. From December 1995 to June 2011, 3,400 psychiatric patients presenting to the Rhode Island Hospital outpatient practice were evaluated with semistructured diagnostic interviews for DSM-IV Axis I and Axis II disorders and measures of psychosocial morbidity. Slightly less than 10% (n = 300) of the 3,400 patients were diagnosed with depressive disorder NOS or adjustment disorder with depressed mood. The patients with depressive disorder NOS were significantly more often diagnosed with social phobia (P depressive disorder NOS reported more anhedonia, increased appetite, increased sleep, and indecisiveness, whereas the patients with adjustment disorder reported more weight loss, reduced appetite, and insomnia. There was no significant difference between the groups in overall level of severity of depression or impaired functioning. The patients with depressive disorder NOS had a nonsignificantly elevated morbid risk of depression in their first-degree relatives. Clinically significant subthreshold depression was common in psychiatric outpatients, and the present results support the validity of distinguishing between depressive disorder NOS and adjustment disorder with depressed mood.

  18. Misophonia: A new mental disorder?

    Science.gov (United States)

    Taylor, Steven

    2017-06-01

    Misophonia, a phenomenon first described in the audiology literature, is characterized by intense emotional reactions (e.g., anger, rage, anxiety, disgust) in response to highly specific sounds, particularly sounds of human origin such as oral or nasal noises made by other people (e.g., chewing, sniffing, slurping, lip smacking). Misophonia is not listed in any of the contemporary psychiatric classification systems. Some investigators have argued that misophonia should be regarded as a new mental disorder, falling within the spectrum of obsessive-compulsive related disorders. Other researchers have disputed this claim. The purpose of this article is to critically examine the proposition that misophonia should be classified as a new mental disorder. The clinical and research literature on misophonia was examined and considered in the context of the broader literature on what constitutes a mental disorder. There have been growing concerns that diagnostic systems such as DSM-5 tend to over-pathologize ordinary quirks and eccentricities. Accordingly, solid evidence is required for proposing a new psychiatric disorder. The available evidence suggests that (a) misophonia meets many of the general criteria for a mental disorder and has some evidence of clinical utility as a diagnostic construct, but (b) the nature and boundaries of the syndrome are unclear; for example, in some cases misophonia might be simply one feature of a broader pattern of sensory intolerance, and (c) considerably more research is required, particularly work concerning diagnostic validity, before misophonia, defined as either as a disorder or as a key feature of some broader syndrome of sensory intolerance, should be considered as a diagnostic construct in the psychiatric nomenclature. A research roadmap is proposed for the systematic evaluation as to whether misophonia should be considered for future editions of DSM or ICD. Copyright © 2017 Elsevier Ltd. All rights reserved.

    2018-02-19

    Suicide is a multicausal human behavior, with devastating and immensely distressing consequences. Its prevalence is estimated to be 20-30 times greater in patients with bipolar disorders than in the general population. The burden of suicide and its high prevalence in bipolar disorders make it imperative that our current understanding be improved to facilitate prediction of suicide and its prevention. In this review, we provide a new perspective on the process of suicide in bipolar disorder, in the form of a novel integrated model that is derived from extant knowledge and recent evidence. A literature search of articles on suicide in bipolar disorder was conducted in recognized databases such as Scopus, PubMed, and PsycINFO using the keywords "suicide", "suicide in bipolar disorders", "suicide process", "suicide risk", "neurobiology of suicide" and "suicide models". Bibliographies of identified articles were further scrutinized for papers and book chapters of relevance. Risk factors for suicide in bipolar disorders are well described, and provide a basis for a framework of epigenetic mechanisms, moderated by neurobiological substrates, neurocognitive functioning, and social inferences within the environment. Relevant models and theories include the diathesis-stress model, the bipolar model of suicide and the ideation-to-action models, the interpersonal theory of suicide, the integrated motivational-volitional model, and the three-step theory. Together, these models provide a basis for the generation of an integrated model that illuminates the suicidal process, from ideation to action. Suicide is complex, and it is evident that a multidimensional and integrated approach is required to reduce its prevalence. The proposed model exposes and provides access to components of the suicide process that are potentially measurable and may serve as novel and specific therapeutic targets for interventions in the context of bipolar disorder. Thus, this model is useful not only

    2018-02-01

    Temporomandibular disorders (TMD) are a subgroup of craniofacial pain problems involving the temporomandibular joint (TMJ), masticatory muscles, and associated head and neck musculoskeletal structures. These disorders are subclassified into TMJ articular disorders and masticatory muscle disorders. Patients with TMD most commonly present with pain, restricted or asymmetric mandibular motion, and TMJ sounds during mandibular movements. The prevalence tends to increase with age. Management of TMJ articular disorders consists of a combination of patient education, home-care plan, biobehavioral therapy, physical therapy, orthotic jaw appliance therapy, pharmacotherapy, and/or surgery. The goal is to increase function, reduce pain, and improve quality of life. Copyright © 2017 Elsevier Inc. All rights reserved.
