The non-ossified pubis.

A group of syndromes is presented whose common characteristic is the absence of pubic ossification at birth with very slow posterior mineralization. This is a radiological finding of interest as it has not been described in other entities. In all the cases shown, moreover, a variable degree of delay in bone age is observed. The increase of space between the pubic bones described in these syndromes is fictious, as it really signifies the existence of non-ossified cartilage. Therefore, they must be differentiated from those which deal with real widening of the symphysis of pubis.

[A new clamp for the anchoring of partial removable prostheses].

The proposed clasp corresponds to two Ney type I clasps acting on one tooth. The two vestibular lower arms are overlapping. The clasp is applied to a cylindrical crown (like a inner telescope) or to the natural crown; it has proved a clinical succes especially in subtotal lower prostheses.

[Ultrasound hysterosalpingography with levovist in the diagnosis of tubaric patency].

UNLABELLED: PURPOSE AIM: To asses the diagnostic value of hysterosalpingo-contrast sonography (HyCoSy) with Levovist(R) as alternative to conventional hysterosalpingography (HSG) in the study of infertility. MATERIAL AND METHODS: From September 1988 to March 2000 we evaluated 120 patients with a history of infertility. Thirty patients underwent both HyCoSy and HSG. HyCoSy was performed in the pre-ovulatory phase of mestrual cycle. The tecnique was the same for both examinations. After administering 15 ml contrast medium, we visualized the endometrial cavity, the flow of the contrast medium along the fallopian tubes and its passage into the peritoneum. RESULTS: In all cases Color-Power Doppler allowed visualization of the uterine cavity and of the spilling of the contrast medium into the peritoneum, yielding information on tube patency that was comparable to that obtained by conventional HSG. In 28 cases (93%) we obtained optimal visualization of the contrast medium at the level of both the endometrial cavity and the fallopian tubes. HyCoSy proved to be superior to conventional HSG in evaluating adjacent myometrial structures, adnexa and degree of follicular maturation, equal to HSG in visualizing the passage of the contrast medium into the peritoneum but inferior to HSG in imaging the fallopian tubes owing to their tortuosity. DISCUSSION AND CONCLUSIONS: The absence of ionising radiation makes HyCoSy a possible first choice examination in the evaluation of fallopian tube pathology. Conventional HSG should be kept for doubtful cases or for surgical procedures to correct mono- or bilateral obstruction.

[Clinical wear of posterior composites].

In our days, Posterior Composites are in the way to replace the traditional and well established materials, such as the amalgam, from the region of the posterior teeth. As time passed however, the first problems connected with these materials were soon to appear. If composites must be used in posterior teeth for occlusal bearing fillings, wear is an important consideration and stands as one of the main problems concerning these materials with serious clinical consequences for the restoration as well as for the occlusion. It is difficult to give an answer to the question concerning the resistance or the behavior of the Posterior Composites to the wear mechanisms. There is no doubt that with the continuous improvement of the Posterior Composites there is also an improvement in the degree of wear. Therefore the purpose of this bibliographical review is to examine the phenomenon of wear and the mechanisms which cause it. We will deal mainly with the clinical study of this phenomenon, while we will also try to explain the behavior from the viewpoint of the wear of the various types of Posterior Composites which are in use today.

The search for hemizygosity at 22qll in patients with isolated cleft palate.

The striking association between oral clefting and the velocardio-facial syndrome (VCFS), a common disorder pathogenetically related to 22q11 deficiency, has prompted the search for this deletion in a group of patients with isolated cleft palate. (CP). Thirty-three patients with posterior CP and 5 with complete CP were included in this study, together with 12 patients with a clinical diagnosis of VCFS. Standard and high resolution chromosome analysis was performed, providing normal results. Southern blotting followed by densitometric analysis and fluorescent in situ hydridization of region 22q11 showed no single case of deletion among the isolated CP patients, while deficiency was found in 10 of 12 VCFS patients. These results demonstrate that hemizygosity at 22q11 is not increased in isolated CP.
