RESUMEN
PURPOSE: There have been only a few reports on the prevalence of torus mandibularis (TM) in young adult patients, and TM can have various adverse effects on oral and occlusal states in middle-age patients. This study was designed to determine the association between TM status and oral and occlusal states in young healthy dentate adults. MATERIALS AND METHODS: This was a cross-sectional study; the sample population included students at Hiroshima University (Hiroshima, Japan) who participated for practical education. The predictor variables in this study included oral symptoms (temporomandibular joint noise, tooth clenching and grinding, buccal mucosa ridging, dental attrition, and tongue habit), oral anatomy (occlusal vertical dimension), and oral function (average occlusal pressure, occlusal contact area, and maximum voluntary tongue pressure). The outcome variable was TM status (present or absent). Additional variables were demographic in nature and included age, number of residual teeth, body weight, and gender. These variables were compared among participants with and without TM using univariate analysis and multiple logistic regression analysis. Statistical analyses were carried out using SPSS Statistics 19 for Windows (IBM Corp, Armonk, NY); a P value less than .05 was considered significant. RESULTS: Of 204 participants included in the study, 50% were men and 50% were women. The mean age was 22.4 ± 2.7 years. TM was present in 119 (58.3%). Multiple logistic regression analysis showed that TM status was associated with dental attrition and occlusal contact area (P < .05). CONCLUSIONS: This study showed that TM was present in more than half the young healthy dentate participants and was closely associated with dental attrition and occlusal contact area. This study will provide readers with useful information to help prevent the development of TM before middle age.

The paracondylar process is a rare osseous process arising at the cervicooccipital region that belongs to a large and heterogenic group of developmental abnormalities of the craniovertebral junction. We present a rare case of a paracondylar process in an 11-year-old girl, in which the diagnosis was made with the use of MRI, thereby skipping X-ray and CT scan, thus avoiding exposure of the young patient to radiation. To our knowledge, the use of MRI has not previously been reported in the investigation and diagnosis of such an abnormality. We describe the details of this variation emphasizing on awareness of this process, its anatomic relationships and its problems to clinicians, radiologists, surgeons and chiropractors.

The optimal surgical management of subclavian vein effort thrombosis remains a dilemma because outcomes after different treatment strategies are only on the basis of small retrospective series. SVT treatment should be on the basis of the cause of thrombosis. Primary effort thrombosis or Paget-Schroetter syndrome frequently necessitates a surgical approach. The type of surgery has to be individualized after careful diagnostic evaluation. We report a congenital clavicular exostosis that had not been identified with chest radiograph and computed tomographic scan that caused SVT in a young woman. This unusual cause of Paget-Schroetter syndrome was treated with a unique approach.
