RESUMO
The position of the TMJ disc in 23 asymptomatic volunteers was determined by ultrasonography imaging. A very low incidence (2.1%) of internal derangements was revealed. The results are discussed in the light of current concepts on the aetiology of TMJ internal derangements. Since ultrasound imaging makes possible noninvasive dynamic investigation of the TMJ arrangements, performance of a prospective long-term study including a sufficiently large group of volunteers is suggested to clarify further the real incidence of TMJ internal derangements.

A case of non-fatal anaphylaxis due to an ampicillin scratch-test is reported. The test technique and the management of the patient are described. The need to use a low-concentration solution for skin testing, and the value of skin tests in the detection of immediate allergic reaction in patients at risk, are stressed.
