Headache And Bruxing Behavior Types In Craniomandibular Disorders (cmds) Patients

Objective. Assess headache and bruxism in Craniomandibular Disorders (CMDs) and non CMDs patients. Method. Clinical examination, questionnaires, headache criteria, severity of bruxism. Results. The prevalence of headache was 68.3% in the CMDs group and 51.4% in the non-CMDs group (p<0.04).Tension type (TTH)=52.8% and combination headaches=25.2% predominated in CMDs. Migraine was more prevalent in Non-CMDs (21.1%) than in CMDs subjects (11.4%). Severe bruxism predominated in the headache/CMDs group=35% as compared to the non-headache/ CMDs group=21%, (p=0.08). We found a frequency of 29.3% extreme bruxism in the headache group and 7% in the non-headache group (p<0.0005). The frequencies of mild/moderate bruxism were about 28% in the TTH, 44.8% in the "other headaches" and 72% in the non-headache/CMDs groups. The frequencies of severe/extreme bruxism were 72.3% in the TTH, 55.2% in the "Other headaches", and 28% in the non- headache/CMDs groups(p=0.0001). Conclusion. Headache, TTH and combination headache were common in the CMDs group. Severe and extreme bruxism were more prevalent in the headache /CMDs group than in the "other headaches" and in the non/headache CMDs groups. Severe and extreme bruxism were more frequent in the TTH/CMDs group.193449457Clark, G.T., Sakai, S., Merrill, R., Flack, V.F., McArthur, D., McCreary, C., Waking and sleeping temporalis EMG levels in

Quantum Monte Carlo simulation for the conductance of one-dimensional quantum spin systems

Recently, the stochastic series expansion (SSE) has been proposed as a powerful MC-method, which allows simulations at low $T$ for quantum-spin systems. We show that the SSE allows to compute the magnetic conductance for various one-dimensional spin systems without further approximations. We consider various modifications of the anisotropic Heisenberg chain. We recover the Kane-Fisher scaling for one impurity in a Luttinger-liquid and study the influence of non-interacting leads for the conductance of an interacting system.Comment: 8 pages, 9 figure

Changes of Several Psychological Measures in the Patients with Craniomandibular Disorders, Bruxing Behavior and Sexual Abuse History

Aim: The understanding of psychological correlates of Craniomandibular disorders and Bruxing Behavior has seen significant progress in the last few years. However, studies evaluating association between more complex psychological measures in such disorders are extremely scarce. To investigate this, we evaluated frequency of sexual abuse history in the experimental and two control groups and scores in depression, somatization and dissociation in those with Craniomandibular Disorders and Bruxism with/without sexual abuse history.Methods: Clinical examination, self-report, chief complaint, criteria for craniomandibular disorders and bruxism, the Becker-Lausen Questionnaire for sexual abuse were used in the Craniomandibular Disorder+ Bruxing Behavior, and in two control subgroups to gather data about sexual abuse history. The Beck Depression Inventory (BDI), 32 questions from the Screening Somatoform Disorders (SOMS-2) instrument and the Dissociative Experience Scale (DES) were used in the Craniomandibular Disorder + Bruxism + Sexual Abuse (n=39), in the Craniomandibular Disorder + Bruxism with no sexual abuse subgroup (n=158) and in the no Craniomandibular Disorders no Sexual Abuse subgroup (n=50) so as to gather data about depression, somatization and dissociation, respectively.Results: We show that there was no a statistically significant difference when comparing frequency of sexual abuse history in the experimental and in the two control groups. Means in depression were about 14.7; 11.4; and 9.3 in the Craniomandibular Disorder + Bruxism and Sexual abuse, in the Craniomandibular Disorder + Bruxism with no sexual abuse history, and in the no Craniomandibular Disorders no Sexual abuse history subgroups, respectively (Kruskall-Wallis statistics with post test p&lt;0.02). Means in somatization were 12.1, 10.3, and 8.0, respectively in those subgroups (p&lt;0.006). Means in dissociation were about 22.3, 15.6, and 15.2, respectively (p&lt;0.007).Conclusions: Means in depression, somatization and dissociation were higher and significantly different in the Craniomandibular + bruxing behavior + sexual abuse history subgroup. This study provides further data on frequency of sexual abuse in craniomandibular disorder and bruxer subjects, expands current knowledge about depression and somatization and provides non previously reported data on dissociation

Six sigma, absorptive capacity and organisational learning orientation

"This is an Accepted Manuscript of an article published by Taylor & Francis in International Journal of Production Research, available online: http://wwww.tandfonline.com/10.1080/00207543.2010.543175."The importance of the Six Sigma methodology in industry is growing constantly. However, there are few empirical studies that analyze the advantages of this methodology and its positive effects on organizational performance. The purpose of this paper is to extend understanding of the success of Six Sigma quality management initiatives by investigating the effects of Six Sigma teamwork and process management on absorptive capacity. It also seeks to understand the relation between absorptive capacity and organizational learning as two sources of sustainable competitive advantage. The information used comes from a larger study, the data for which were collected from a random sample of 237 European firms. Of these 237 organizations, 58 are Six Sigma organizations. Structural Equation Modelling (SEM) was used to test the hypotheses. The main findings show that Six Sigma teamwork and process management positively affect the development of absorptive capacity. A positive and significant relationship is also observed between absorptive capacity and organizational learning orientation. The findings of this study justify Six Sigma implementation in firms. This study provides us with an in-depth understanding of some structural elements that characterize the Six Sigma methodology, enabling us to provide an explanation for its success

Reducing the environmental impact of surgery on a global scale: systematic review and co-prioritization with healthcare workers in 132 countries

Background Healthcare cannot achieve net-zero carbon without addressing operating theatres. The aim of this study was to prioritize feasible interventions to reduce the environmental impact of operating theatres. Methods This study adopted a four-phase Delphi consensus co-prioritization methodology. In phase 1, a systematic review of published interventions and global consultation of perioperative healthcare professionals were used to longlist interventions. In phase 2, iterative thematic analysis consolidated comparable interventions into a shortlist. In phase 3, the shortlist was co-prioritized based on patient and clinician views on acceptability, feasibility, and safety. In phase 4, ranked lists of interventions were presented by their relevance to high-income countries and low–middle-income countries. Results In phase 1, 43 interventions were identified, which had low uptake in practice according to 3042 professionals globally. In phase 2, a shortlist of 15 intervention domains was generated. In phase 3, interventions were deemed acceptable for more than 90 per cent of patients except for reducing general anaesthesia (84 per cent) and re-sterilization of ‘single-use’ consumables (86 per cent). In phase 4, the top three shortlisted interventions for high-income countries were: introducing recycling; reducing use of anaesthetic gases; and appropriate clinical waste processing. In phase 4, the top three shortlisted interventions for low–middle-income countries were: introducing reusable surgical devices; reducing use of consumables; and reducing the use of general anaesthesia. Conclusion This is a step toward environmentally sustainable operating environments with actionable interventions applicable to both high– and low–middle–income countries

Odontogenic Myxoma In The Maxilla: A Case Report And Characteristics On Ct And Mr

The findings of a computed tomography (CT) and magnetic resonance (MR) are reported in this study for a odontogenic myxoma arising in the maxilla of a 22 years-old Brazilian woman. The CT showed an expansive formation of circular aspect located in the alveolar process of the left maxilla with slight heterogeneous distinction after iodinized contrast. Unilateral crowding with displacement of some dental elements inside the lesion was shown in the MR and CT images. The MR images showed a well-defined and smooth-walled mass lesion with low signal intensity on T1-weighted images and high-signal intensity on T2-weighted images. The treatment of choice was a surgical tumoral resection and three applications of cryotherapheutic agent for 1 min in the same surgical time with interval of 5 min between them. © 2005 Elsevier Ltd.
