Temporomandibular joint involvement in juvenile idiopathic arthritis : treatment with an orthodontic appliance
No full textIntroduction and purpose: About 65% of children suffering from juvenile idiopathic arthritis (JIA) shows a more or less marked involvement of temporo-mandibular joint (TMJ) with altered mandibular growth, resorption of the condyles, occlusary instability, reduced chewing ability and facial dysmorphia. The purpose of our study is to prevent and to treat the progressive evolution of JIA on craniofacial growth and morphology with a functional appliance; surgery should be considered only in so far as the adequacy of TMJ movement is concerned. Methods: From 1992 until now 72 children with proved JIA and TMJ involvement have been treated (50 females, 22 males, aged 6 to 16 years old). TMJ involvement was bilateral in 61% and unilateral in 39% of patients. A diagnostic workup was carried out involving tomograms of TMJ and cephalometric radiograph and analysis. The authors used a bimaxillary activator in the attempt to modify the unfavourable growth pattern and provide a gradual ante-rotation of the jaw. Results: Almost all JIA patients showed satisfactory long term results, easing of pain, reduced skeletal discrepancy, increased function and good facial profile. Conclusions: The long term results of this study indicate that orthopaedic therapy might control the vicious circle of the malocclusion in children with JIA, preventing exacerbation of mandibular clockwise rotation. Surgical intervention for the improvement of TMJ function should be considered only if a severe restricted state is imminent
Densitometria ossea: parametri ultrasonometrici in giovani sani
No full textBackground. This study was carried out in order to assess the possible changes of ultrasonometric parameters of bone (SOS, BUA, Stiffness) related to age in a normal male and female Italian population. Methods. A total of 150 healthy subjects subdivided into 2 groups (80females and 70 males) have been studied. The patients have been submitted to a careful anamnesis and clinical observation; the examination has been performed by placing the foot inside the ultrasonograph. Results. The results obtained show that there is a linear increase of SOS, BUA and Stiffness with age in the normal population and a similar pattern is observed in both sexes. Conclusions. These findings suggest that ultrasound parameters are able to detect and monitoring characteristics of bone structure. Therefore, ultrasound measurement should be considered as an alternative to radiation quantitative based methods for the assessment of the skeleton
Artrite Psoriasica : coinvolgimento dell’articolazione temporomandibolare come prima manifestazione articolare
No full textL'Artrite Psoriasica (AP) è una malattia sistemica cronica difficile da individuare. La diagnosi è fatta principalmente su dati clinici basati sul reperto di psoriasi e artrite infiammatoria delle articolazioni. Molti report hanno descritto gli effetti lesivi dell’AP sull’articolazione temporomandibolare (ATM), ma nessuno studio ha chiaramente riportato come l’ATM possa essere la prima articolazione a essere coinvolta nell’AP. Questo articolo riporta un caso di AP che era stato diagnosticato parecchi anni dopo l’esordio del danno temporomandibolare perché non era presente nessun altro segno oltre la psoriasi. La mancata diagnosi precoce ha causato un severo danno dell’ATM. L’ATM può essere la prima articolazione coinvolta nell’AP. Per una corretta e precoce diagnosi di AP, è fondamentale una stretta collaborazione tra odontoiatra e reumatologo
