Temporomandibular disorders are characterized by ear pain, tinnitus, difficulty in chewing, dysphagia and also dizziness, cervical limitation of range of movement (ROM) and other less common disorders. Numerous recent studies associate the presence of these signs and symptoms with an elongated styloid apophysis, as in the case of Eagle syndrome. The purpose of this clinical case is to support the thesis of a common syndrome that temporomandibular joint (TMJ) disorders with an elongated styloid process affirming the relationship between temporal bone, mandibule, hyoid bone and tongue. The patient was a 57-year-old woman who reported having ear algia and tinnitus all on the right side with difficulty chewing accompanied by odynophagia and dysphagia of solid and liquid foods, as well as cervical disorders. Computed tomography (CT) scans of the neck showed elongation and ossification of the styloid processes of the temporal bone. Magnetic resonce imaging (MRI) showed an anterior right dislocation of the TMJ articular disc. The patient presented classic symptoms of temporomandibular disorders, with the primary examitions showing an anterior right dislocation of the articular disc of the TMJ, as well as a longer styloid process on the same side. We therefore suggested that, in this case report, TMJ disorders may be associated with a longer styloid process on the same side.

The aim of this article is to review hydrogen combustion applications within the energy transition framework. Hydrogen blends are also included, from the well-known hydrogen enriched natural gas (HENG) to the hydrogen and ammonia blends whose chemical kinetics is still not clearly defined. Hydrogen and hydrogen blends combustion characteristics will be firstly summarized in terms of standard properties like the laminar flame speed and the adiabatic flame temperature, but also evidencing the critical role of hydrogen preferential diffusion in burning rate enhancement and the drastic reduction in radiative emission with respect to natural gas flames. Then, combustion applications in both thermo-electric power generation (based on internal combustion engines, i.e., gas turbines and piston engines) and hard-to-abate industry (requiring high-temperature kilns and furnaces) sectors will be considered, highlighting the main issues due to hydrogen addition related to safety, pollutant emissions, and potentially negative effects on industrial products (e.g., glass, cement and ceramic).

The role of the dento-mandibular apparatus and, in particular, occlusion and jaw position, received increased attention during last years. In the present study, we aimed to systematically review, on the light of the new potential insights, the published literature covering the occlusal splint (OS) applications, and its impact on exercise performance. A structured search was carried out including MEDLINE®/PubMed and Scopus databases with additional integration from external sources, between March and June 2021. To meet the inclusion criteria, studies published in the English language, involving humans in vivo, published from 2000 to 2021 and that investigated the role of occlusal splints on athletes’ performance were selected. Starting from the 587 identified records, 17 items were finally included for the review. Four main aspects were considered and analyzed: (1) occlusal splint characteristics and occlusion experimental conditions, (2) jump performance, (3) maximal and explosive strength, and (4) exercise technique and biomechanics. The results of the systematic literature analysis depicted a wide heterogenicity in the experimental conditions and suggested the application of the OS as a way to improve athletes’ or individuals’ oral health, and as a potential tool to optimize marginal aspects of exercise performance.

Purpose : This study is aimed to preliminary investigate whether transcranial alternating current stimulation (tACS) could affect explosive power considering genetic background in sport subjects. Methods : Seventeen healthy sports volunteers with at least 3 years of sports activities participated in the experiment. After 2 weeks of familiarization performed without any stimulation, each participant received either 50 Hz-tACS or sham-tACS. Before and after stimulation, subjects performed the following tests: (1) the squat jump with the hands on the hips (SJ); (2) countermovement jump with the hands on the hips (CMJ); (3) countermovement jump with arm swing (CMJ-AS); (4) 15-s Bosco’s test; (5) seated backward overhead medicine ball throw (SBOMBT); (6) seated chest pass throw (SCPT) with a 3-kg rubber medicine ball; and (7) hand-grip test. Additionally, saliva samples were collected from each participant. Genotyping analysis was carried out by polymerase chain reaction (PCR). Results : No significant differences were found in sport performance of subjects after 50 Hz-tACS. Additionally, we did not find any influence of genetic background on tACS-related effect on physical performance. These results suggest that tACS at gamma frequency is not able to induce an after-effect modulating sport performance. Further investigations with larger sample size are needed in order to understand the potential role of non-invasive brain stimulation techniques (NIBS) in motor performances. Conclusions : Gamma-tACS applied before the physical performance fails to improve explosive power in sport subjects.

The craniocervical-mandibular system works in harmony and allows different functiol tasks as the postural control of the cervical region. This system is formed by the temporomandibular joint, the masticatory muscles and ligaments connecting the temporomandibular joint and the cervical region. It has been seen to affect human posture, and many disorders of the temporomandibular joints may affect this functiol arrangement. Notwithstanding this system considered as a functiol arrangement, may offer various clinical explations, it does not hold atomical connections with the posterior region of the cranium, thus it should not be refered to as a craniocervical arrangement. For this reason a new interpretation of such system as the tongue, mandible, hyoid system should be considered. Such functiol reinterpretation between these three atomical structures allows further comprehension of specific clinical conditions connected to deglutition aspects or the temporomandibular joint, for such needs to be taken into account during clinical diagnosis and treatment.

Ingrown toeils account for roughly 20% of all foot problems in primary care. It is most common in young men, with il care habits and footwear being major contributors. Onychocryptosis is typically caused by self-treatment attempts to cure the condition in its early stages. Its clinical features are frequently confused with other osseous and soft tissue abnormalities. The goal of this study was to provide perspectives on the magement of pain and inflammation in Onychocryptosis using an Ozoile-based hydrogel formulation in a semi-occlusive bandage for 14 days, while incorporating tural pharmacological solutions into established protocols. The primary outcomes measured were pain reduction on NRS and stadiation according to the Al Kline Classification. The reduction was statistically significant, with a mean decrease in VAS score from 10 to 4 (p < 0.05), and Al Kline classification decreased by an average of 1.6 stages. 42% of patients recovered within the first 15 days of treatment, and 93% by the end of the scheduled treatment.

Promotion of oral health has an essential role in the maintence of teeth in adults. However, health education must start from an early age, in order to monitor the child's growth and prevent pathologies. Schools are in charge of the overall education of children and of guidance to parents but could also be engaged in the promotion of oral health, supported and counseled by pediatricians and dentists. The purpose of this pilot study is to evaluate whether school age children could be taught, successfully, basic oral sciences and dental hygiene, by a professiol, during school hours. In this pilot study, an anonymized test was administered to 45 children of age between 8 and 10, both before and after an interactive lecture on oral health, to assess the effectiveness of the lesson and acquisition by the children of knowledge on oral health. After the presentation, the majority of the children were able to answer correctly to the questionire that was given to them (test, retest) which was related to dental atomy and pathology (number of teeth, cavities, halitosis), and dental hygiene tools and practices (brushes, floss, mouth wash, tongue scrapers). The children seemed to be receptive to learning while in school, and a specific educatiol session of dental hygiene and oral health seems to be the right approach to ensure children can identify dental hygiene tools and use them appropriately.

Adolescent Idiopathic Scoliosis (AIS) is a three-dimensiol spil deformity that, if untreated, can impair posture, biomechanics, and quality of life. This case report aims to present the clinical outcomes of an innovative conservative treatment approach that combines the PosturalSpine® D’Amanti Method with the Chêneau brace, in an 8-year-old patient with thoracolumbar rotoscoliosis. This integrative method may represent a novel altertive to conventiol bracing or physiotherapy-only protocols. An 8-year-old girl diagnosed with a 32° thoracolumbar rotoscoliosis likely of hereditary origin underwent a 36-month treatment program at Studio Kinesis in Ragusa. The intervention combined a Chêneau brace with the PosturalSpine® D’Amanti Method, which includes proprioceptive and biomechanical exercises. The protocol involved eight 30-minute sessions per month, focusing on spil alignment, posture, breathing, and body awareness. Radiographic evaluations were conducted at baseline and 10th, 24th, and 35th months. The Cobb angle improved from 32° to 12°, with the most notable reduction occurring within the first 12 months. A slight increase was observed, which may correspond with a 12.5 cm growth spurt, suggesting the influence of rapid growth on treatment outcomes. The integration of PosturalSpine® D’Amanti Method with the Chêneau brace showed encouraging results in reducing spil curvature and enhancing postural alignment with a noticeable reduction of rib hump in a pediatric patient. This case highlights the potential of combining kinesiotherapy and bracing in scoliosis magement. However, broader studies are necessary to validate these findings and optimize protocols for long-term care, particularly during growth phases.

Choking (or foreign body airway obstruction) is a widespread phenomenon with serious consequences of morbidity and mortality. Choking (often also called suffocation) can be caused by food or inedible objects and leads to various degrees of asphyxiation or lack of oxygen in the blood stream. The incidence is very high in both young children and adults, especially seniors. However, since not all choking episodes end up in the emergency room or become fatalities, they often escape statistics. Although episodes of choking from non-edible bodies are infrequent, they affect mostly young children. Three of the most common risks for choking in general are neurological disorders, dysphagia and dental issues (few or no teeth, unstable or unsuitable prosthesis or orthodontic appliances). The purpose of this study was to evaluate the risk factors of choking and ways to reduce/avoid this event. We reported data on a series of 138 patients admitted to the emergency department following a choking event, at a hospital in Rome, Italy. The age group of the alyzed population ranged from 1 to 88 years, with the most represented age group of these between 40 and 59, with a similar distribution between males and females. The types of foods on which people choked reflected the seasol, traditiol and local foods: 67% of patients reported choking on fish bones followed by meat bones (9%) and artichokes (3%). Three relevant non-food choking elements reported were: orthodontic items, toothpicks and pins (one occurrence each). We also reported on two clinical cases of patients choking on meat and a chicken bone. In conclusion, choking awareness and prevention are essential for implementing potential life-saving precautions. Prevention is the first tool to reduce the occurrence of this event, therefore it is necessary to alyze the risk factors and educate the population to elimite them. Proper chewing and oral manipulation are paramount functions in preventing choking, along with meal-time supervision if little children and elderly. Then, it behooves the healthcare professiols to dissemite knowledge

Practicing physical activities or sports that involve frequent jumping and landing can strain the muscles and joints of the lower limbs, especially in those who do not have adequate physical preparation. The objective of this study was to (a) determine the correlation between ankle range of motion (ROM) and landing stability following jumps; (b) assess the association between the jump height in a counter-movement jump (CMJ) test and ankle ROM; and (c) examine the connection between stabilometry during specific jumps movements present in many sports and in ankle stabilization. Sixty-two healthy amateur volleyball players participated in the study (age: thirty-seven females and twenty-five males; age (years): 16.5 ± 4.25; height (cm): 166 ± 11.4; weight (Kg): 61.6 ± 13.7). Participants were recruited for the study in collaboration with student sports associations. The evaluations encompassed the measurement of ankle joint mobility for both lower limbs using an inertial sensor, a static baropodometric and stabilometric analysis using a pressure platform, and the CMJ test using the Microgate system. After the assessments, participants performed a “specific jump landing task”. Significant correlations were found between foot range of motion (ROM) and counter-movement jump (CMJ) performance. Specifically, the ROM of the right foot had a strong correlation with the CMJ (r = 0.81, p < 0.001), while the left foot ROM showed a moderate correlation (r = 0.46, p < 0.001). The specific jump task revealed substantial changes in stabilometry parameters, particularly during forward hops compared to lateral jumps. Dorsiflexion ROM significantly impacts jumping ability. Evaluating landing patterns and stabilometry during targeted activities can help optimize training, improve dynamic balance, and reduce ankle injury risk.
