[Intracoronary brachytherapy: a meta-analysis].

Intracoronary brachytherapy aims at a reduction of in-stent restenosis by lessening neo-intimal proliferation. To assess its clinical potential, a systematic review of the literature indexed in the standard biomedical bibliographic databases selected eight prospective randomized clinical trials; seven of them, comparing coronary brachytherapy and non-treatment or placebo, have been included in the present meta-analysis. This analysis confirms the angiographic benefit of this procedure, as reported in the individual studies; it also shows, however an excess of clinical adverse effects not exhibited by any individual trial. Therefore, intracoronary brachytherapy cannot be recommended as routine practice, while one cannot rule out its interest in special situations.

[Very large mandibular keratocysts: review].

The odontogenic keratocyst (OKC) is unique among odontogenic cysts of the jaws, especially because of the high risk of recurrence. Epidemiological studies demonstrate male predominance and the most common location in the mandible. We reviewed our own experience with eight patients and data in the literature, focusing on very large mandibular keratocysts. We reviewed the clinical, radiological, and histological elements required for the positive and differential diagnosis. CT scans should be performed for very large cysts due to their superiority over plain x-rays, both for treatment planning and follow-up. Surgical treatment is indicated. The choice remains controversial between radical and conservative approach. We prefer conservative treatment. Problems concerning bone healing, recurrence and follow-up are also discussed.

[Investment and operating costs of the electron beam scanner at the Broussais Hospital].

Cost of Imatron and of its building was 150,000,000 FF in 1989, highly more expensive than for other CT. Cost of "maintainance" is only 9.5% of its acquisition price against 21% for other CT. The replacement of high power and detectors is less frequent in Imatron than X ray tubes in the other CT. Imatron was often out of order during the 2 first years because of high power. Now the time devoted to break down is only 2.5%. A slice price is 4.75 FF for Imatron and the mean slice price is 7.38 FF for the other Assistance Publique CT (from 4.88 to 10.53).

[Serological studies of a pygmy population in Cameroon].

Serological studies made in a community of 106 pygmies led to 60% positive reactions with parasitic antigens, mainly of nematodes and trematodes. IgG and IgM levels are increased (about two times and four times the levels found in a normal population). These results prove the importance of these infestations by human or animal parasites in a tropical forest population.
