[A rare dental abnormality: "the phantom tooth" or "odontodysplasia". Apropos of a case].

"Phantom tooth" or "odontodysplasia" is one of the most unusual and rare of dental abnormalities, being characterised: Clinically, by the topography of the lesions, the involvement of both sets of teeth and abnormalities in the size and form of the teeth which remain unrupted or only partially evolved. Radiologically, by transparency of the teeth to X-rays. Histologically, by disorganisation of the dental structures and a highly characteristic appearance of the enamel and, in particular, dentine. On the basis of one case, the authors review in detail each aspect of these characteristics, paying special attention to histology and the information obtained using the sweep electron microscope.

[Use of very high doses of haloperidol in the treatment of acute psychotic episodes. Clinical and pharmacokinetic analysis apropos of 15 cases].

High-dosage haloperidol treatment was administered during three weeks in a rapid neuroleptization technique to fifteen patients suffering from acute psychotic episodes. Haloperidol plasma levels were determined by radioimmunoassay. The efficacy of such a therapeutic design seemed fairly good, particularly the rapid improvement during the first week. Yet, tolerance appeared to be low, with a high incidence of adverse effects, some of them unexpected. A very good correlation was observed between haloperidol plasma levels and haloperidol oral doses. By contrast, there was no correlation between plasma levels and clinical improvement. In the same way, the occurrence of adverse effects did not seem to be related to haloperidol plasma levels.
