Alterations in kinematics of temporomandibular joint associated with chronic neck pain

alexandrossfakianakis shared this article with you from Inoreader Alterations in kinematics of temporomandibular joint associated with chronic neck pain via Journal of Oral Rehabilitation Abstract Background Temporomandibular disorder (TMD) is an umbrella term for pain and dysfunction of the temporomandibular joint (TMJ) and its associated structures. Patients with TMD show changes in TMJ kinematics and masticatory muscle activation. TMD is commonly comorbid with non-specific chronic neck pain (NCNP), which may be one of the risk factors for TMD. Objectives This study aimed to investigate whether patients with NCNP have altered TMJ kinematics and masticatory muscle activity. Methods This was a cross-sectional exploratory study including 19 healthy participants and 20 patients with NCNP but without TMD symptoms. TMJ kinematics was measured during mouth opening and closing, jaw protrusion and jaw lateral deviation. Surface electromyography was used to record the muscle activity of the anterior temporalis, masseter, sternocleidomastoid, and upper trapezius while clenching. Furthermore, cervical posture, cervical range of motion (ROM), and pressure pain threshold of the neck and masticatory muscles were measured. Results Compared with the healthy group, the NCNP group showed significantly reduced upper cervical rotation ROM (p=0.041), and increased condylar path length (p=0.02), condylar translation (opening p=0.034, closing p=0.011), and mechanical pain sensitivity of the upper trapezius (p=0.018). Increased condylar translation was significantly correlated with reduced upper cervical mobility and poor cervical posture (r=−0.322 to −0.397; p=0.012–0.046). Conclusion Increased condylar translation and path length in patients with NCNP may indicate poor control of TMJ articular movement, which may result from neck pain or may be a compensation for limited neck mobility. Evaluation of excessive TMJ translation may be considered in patients with NCNP. View on Web

Correlation between the intensity of Helicobacter pylori colonization and severity of gastritis: Results of a prospective study

alexandrossfakianakis shared this article with you from Inoreader Correlation between the intensity of Helicobacter pylori colonization and severity of gastritis: Results of a prospective study via Helicobacter Abstract Helicobacter pylori infection is strongly associated with chronic gastritis and is probably the main course of chronic inflammation in the gastric mucosa. Gradually, H. pylori gastritis will result in gastric atrophy and intestinal metaplasia. Identifying the relationship between intensity of colonization and activity of gastritis helps the clinician in more effective treatment and post-treatment follow-ups. The aim of our work was to analyze the relationship between the density of H. pylori colonization of the gastric mucosa and the severity of histological parameters of gastritis (inflammation activity, gastric atrophy, and intestinal metaplasia). This was a prospective monocentric study conducted from January 2020 to December 2020, collecting patients naive to any anti-H. pylori treatment and having a chronic H. pylori infection documented by histological examination. Epidemiological, endoscopic, and anathomopathological da ta were collected. Ninety-seven patients with a mean age of 42.6 years [18–65 years] and a sex ratio of M/F = 0.64 were included. The density of H. pylori colonization was mild (+) in 43.3% of patients, moderate (++) in 47.4% of patients, and significant (+++) in 9.3% of patients. Nearly, ten per cent of patients had no gastritis, 33% had mild gastritis, 50.5% had moderate gastritis, and 6.2% had severe gastritis. Gastric atrophy and intestinal metaplasia were found in 44.3% and 10.3% of our population, respectively. Patients with mild H. pylori colonization rates had the highest level of mild activity (59.5%). There was a statistically significant association between the severity of H. pylori infection and gastritis activity (p < .001). Gastric atrophy was significantly associated with the intensity of H. pylori colonization (p = .049). No significant relationship was found between the in tensity of colonization and metaplasia (p = .08). Our study shows that there is a statistically significant association between the density of H. pylori and histopathological findings including gastritis activity and intestinal atrophy. View on Web

A Nomogram to Predict Nodal Response after Induction Chemotherapy for Hypopharyngeal Carcinoma

alexandrossfakianakis shared this article with you from Inoreader A Nomogram to Predict Nodal Response after Induction Chemotherapy for Hypopharyngeal Carcinoma via The Laryngoscope This study is the first to establish and validate a nomogram based on five critical predictors, including tumor differentiation degree (DD), T classification, metastatic lymph node size (LS), number of lymph node metastases (NOL), and cervical nodal necrosis (CNN), to predict the response of metastatic lymph nodes after induction chemotherapy (ICT) for hypopharyngeal carcinoma patients. Our nomogram yielded relatively good accuracy in predicting the regional ICT response, which will be a useful tool to assist clinicians in future decision-making. Background For hypopharyngeal carcinoma, metastatic neck nodes with a low response to induction chemotherapy (ICT) should not be managed with concomitant chemoradiotherapy (CCRT), and the prediction of chemosensitivity before ICT could prevent adverse events from occurring during chemotherapy. In this study, we developed a nomogram to predict the regional response to ICT. Methods A total of 153 hypopharyngeal carcinoma patients with regional metastasis treated with ICT in our institution from January 2010 to September 2020 were retrospectively studied. According to ICT response evaluated by RECIST 1.1, patients were divided into chemo-insensitive (PR < 70%/SD/PD) (group 1) and chemosensitive (CR/PR ≥ 70%) (group 2) groups. Patients' clinical, image, and hematologic data before ICT were collected. The nomogram was built based on multivariate analysis and stepwise logistic regression and was evaluated from the aspects of discrimination and calibration. Results A nomogram based on five critical predictors, namely, tumor differentiation degree, T classification, metastatic lymph node size, number of lymph node metastases, and cervical nodal necrosis, was developed. The areas under the curve (AUC) values were 0.76 and 0.70 after adjusting the results using bootstrap methods. The calibration curve showed relatively good agreement between the predicted and observed probabilities. Conclusions Our nomogram yielded good accuracy in predicting the regional ICT response and will be a useful tool to assist clinicians in decision making.

Temporomandibular disorders, bite force and osseous changes of the temporomandibular joints in patients with hypermobile Ehlers‐Danlos Syndrome compared to a healthy control group

alexandrossfakianakis shared this article with you from Inoreader Temporomandibular disorders, bite force and osseous changes of the temporomandibular joints in patients with hypermobile Ehlers‐Danlos Syndrome compared to a healthy control group via Journal of Oral Rehabilitation SUMMARY Background Ehlers-Danlos syndrome (EDS) is a hereditary disorder that affects the connective tissue and collagen structures in the body characterized by joint hypermobility, skin hyperextensibility and tissue fragility. Objective The aim was to investigate temporomandibular disorders (TMD), bite force, teeth in occlusal contact and osseous changes of the temporomandibular joints (TMJs) in 26 patients with hypermobile EDS (hEDS), differentiated by a genetic test, compared to 39 healthy controls. METHODS: Clinical examination according to Diagnostic Criteria for Temporomandibular Disorders (DC/TMD), radiological examinations of the TMJs by cone-beam computed tomographic (CBCT) scans, registration of bite force and teeth in occlusal contact was performed. Statistical analyses included Fisher's Exact Test, multiple logistic and linear regression models adjusted for age, gender and Body Mass Index (BMI). Results Single symptoms and signs of TMD occurred significantly more often in hEDS (p=0.002; p=0.001; p=0.003; p=<0.0001; p=0.012) and maximum mouth opening was significantly smaller in hEDS compared to controls (p=<0.0001). The DC/TMD diagnosis myalgia, myofascial pain with referral, arthralgia, headache attributed to TMD, disc displacement disorders and degenerative joint disease occurred significantly more often in hEDS compared to controls (p=0.000; p=0.008; p=0.003; p=0.000; p=<0.0001; p=0.010, respectively). No significant differences were found in bite force and in teeth in occlusal contact between the groups (p>0.05). On CBCT of the TMJs, subcortical sclerosis occurred significantly more often in hEDS compared to controls (p=0.005). Conclusion Symptoms and signs of TMD and osseous changes of the TMJs occurred significantly more often in hEDS. Bite force and teeth in occlusal contact were comparable to controls. View on Web
