[Radiological aspects of giant cementoma of the jaws (Pindborg)]. / Les aspects radiologiques du cémentome géant des maxillaires (Pindborg).

In reference to 7 cases of Pindborg's giant cementoma in Senegalese women, the authors describe their radiological aspects. The different aspects of these tumors are emphasized according to their location on the maxilla or the mandible and whether they are anterior or posterior.

[Mandibular fractures caused by a machete. Apropos of 3 cases]. / Les fractures mandibulaires par coupe-coupe. A propos de 3 observations.

The authors report on 3 cases of facial trauma with mandibular fracture caused by machete, and associated to more or less deep lesions of cutaneo-muscular coating planes and noble intra-facial organs. Treatment of such traumas must be performed in an emergency surgical unit, after a thorough check-up of the lesions. It is a traumatology peculiar to Peulh population, to be classified in the etiologic chapter of assaults.

[Delayed filling of the anterior interventricular artery. Apropos of 9 cases]. / Retard de remplissage de l'artère interventriculaire antérieure. A propos de 9 cas.

Selective coronary angiography has shown that typical angina pectoris may occur in the absence of atheromatous coronary stenosis. Other causes of these attacks of pain have been found: coronary spasm, small vessel disease, abnormal dissociation of haemoglobin or metabolic disturbances of the myocardial cell. Of all the patients undergoing coronary angiography in 1984 at the Centre Cantini, 9 had no classical coronary lesions but delayed filling of the left anterior descending artery. This syndrome was described for the first time in 1972 by Tambe as the "slow flow velocity syndrome". The aim of this study was to analyse the clinical, ECG and haemodynamic profiles of those patients. Five of them also underwent stress Thallium myocardial scintigraphy. An ergometrine provocation test was performed afterwards under ECG control. Delayed filling was appreciated by comparison with the other vessels and also by measuring the filling time which was two or three times longer than in a control series of 9 patients with angina and normal coronary arteries. The difference was statistically significant. These findings were only observed in strictly normal coronary vessels; they were reproducible and unaffected by the administration of nitrate derivatives. In our series all 9 patients were men with an average age of 51.4 years. One patient was asymptomatic and had a history suggestive of myocardial infarction, and 4 others had typical angina of effort: all had abnormal exercise stress tests. The other 3 patients had spontaneous atypical chest pain, normal resting ECG and a negative exercise stress test (impossible in one case). The five stress Thallium scintigraphies showed myocardial perfusion defects.(ABSTRACT TRUNCATED AT 250 WORDS)
