Tinnitus, also called phantom auditory perception, is a major health problem in western countries. As such, a significant amount of effort has been devoted to understanding its mechanisms, including studies in animals wherein a supposed "tinnitus state" can be induced. Here, we studied on the same awake animals the effects of a high-dose of salicylate and… (More)
Lingual nerve damage is one of the most common complications of lower third molar removal. However evaluation of the factor involved in these lesions is difficult since most previous series are heterogeneous. The purpose of this prospective randomized study was to ascertain the impact of lingual nerve protection in a homogeneous series including only… (More)
We employ a life-cycle model with income risk to analyze how tax-deferred individual accounts affect households' savings for retirement. We consider voluntary accounts as opposed to mandatory accounts with minimum contribution rates. We contrast add-on accounts with carve-out accounts that partly replace social security contributions. Quantitative results… (More)
This paper employs a life-cycle model with exogenous stochastic labor income to analyze how different types of individual retirement accounts affect households' savings and portfolio allocation as well as welfare. We consider voluntary accounts as opposed to mandatory accounts that require a minimum contribution rate. Moreover, we contrast add-on accounts… (More)
Posterior displacement of the temporo-mandibular joint disk is exceptional. The most typical clinical sign is sudden onset unilateral molar open bite. This lateral open bite is accompanied by a sensation of an intra-articular foreign body and more rarely by painful episodes. The joint sounds are not characteristic. Mouth opening is slightly limited. There… (More)
In literature, the authors demonstrate that progressive distraction osteogenesis, according to the Ilizarov method, is applicable to the mandible. Mandibular distraction is achievable through external approach or through oral approach. Further experimental and clinical studies will be necessary to define the most stable apparatus and the best indications… (More)
With reference to a case reported here, the authors emphasize the importance of reducing the length of the ramus of the jaw in rather exceptional forms of gaps between the upper and lower jaws with an increase in the posterior height of the face. This procedure provides more stable results and the patient's gums are no longer revealed when smiling.
