[The maxillofacial surgeon faced with the HIV-positive patient: risks and prevention].

Prevention against the transmission of the HIV must be universal today, which means that it applies to all patients. Blood, tissues, the CSF are infected, but nasal secreta, tears and saliva are not contaminated unless they contain blood. The statistical risk of an HIV serological conversion when making an injection is an estimate of 0.1 to 0.3%, one hundred times less than with the hepatitis B virus. The best protection for maxillofacial surgeons, who are very exposed by the manipulation of objects (needle, wires) and by considerable projections of blood (rotary motor) is not a systematic HIV serological test for all patients, but goggles with side screens, a double pair of gloves and the use of an antiseptic acting on the HIV in case of staining.

Cherubism. Findings in three cases in the same family.

Cherubism is a benign hereditary giant-cell lesion of the mandibular and maxillary spongiosa which appears during childhood between the age of 2 and 5 years and progresses until puberty when it spontaneously regresses. It appears as a bilateral, painless swelling. It normally requires no treatment. Three children in the same Algerian family who suffered from this disease were brought to our department. Radiographic examinations were carried out, giving good definition of the lesions. The 3 patients were finally operated on, as operative treatment was, effectively, necessary.

[Cervical lipoma or Launois-Bensaude syndrome].

The authors report a clinical case of a borderline form between two types of lipomatosis: simple lipoma and Made-lung's disease. The authors review the clinical features of these two diseases and stress the fundamental importance of the intraoperative appearance. The diagnosis in the present case was that of cervial lipoma.

[Cherubism. Apropos 3 cases].

Cherubism is a benign hereditary giant-cell lesion of the mandibular and maxillary spongiosa which appears during childhood between 2 and 5 years old and progresses until puberty when it spontaneously regresses. It appears under the form of a bilateral painless swelling. It normally requires no treatment. Three children of a same algerian family who suffered from this disease were brought into our ward. Radiographic examinations were realized among which scanner allowed the establishment of a good definition of the lesions. The 3 patients were finally operated, the surgical intervention having been effectively necessary.

[Restoration of the alveolar crest with a biomaterial filler. A clinical and histological study].

The implantation of biocompatible hydroxyapatite is used for human mandibular ridge augmentation in edentulous patients. Histologically, we studied such a material after a long period of implantation (1 1/2 to 2 years) in two patients. The histologic study showed a narrow meshed net of collagen tissue surrounding the hydroxylapatite particles. In the periphery of that tissue, we could see an osteogenesis: the bony trabeculae thus formed firstly were made of an immature bony matrix with an irregular "woven" pattern; secondarily, a mature bone, quite similar to the normal bone, occurred. In our two observations, there was an unusual inflammatory reaction characterized by cellular infiltration of lipophages, lymphocytes and plasma cells in the connective tissue and in one case by a true ischaemic necrosis with granuloma and bacteria. In spite of that inflammation, the whole material was well tolerated, without foreign-body granuloma. Such a granuloma was only found in superficial areas of the gingiva, around extruded particles of the biomaterial.
