No full textEarly clinical diagnosis of solitary plasmacytoma of the jaws: a case report with a six year follow-up.
No full textThe authors reported a case of a solitary mandibular plasmacytoma in a 53-year-old male Caucasian patient. The histological examination of the specimen was positive for a plasmacytoma with anaplastic appearance. Since the patient refused a demolitive surgical treatment, he was treated with a local radiation therapy of 4000 rads over a 20-day period and polychemotherapy with cyclophosphamide, prednisone and melphalan. Six years after starting radiation treatment the patient is free of recurrent primary disease and not affected by multiple localization. In conclusion, the solitary bone plasmacytoma represents an initial stage of the multiple myeloma rather than a distinct clinical pathology. Unfortunately, the diagnosis of the plasmacytoma is only rarely carried out in the early phases of the disease. The importance of the identification of the initial stage without a clear M component, as in the reported case, is self-evident, since the prognosis is related to the mass of plasmacytoma cells that are present at the time of the diagnosis. The purpose of this study is to report an extremely rare case of solitary bone plasmacytoma with a mandibular localization treated with radio- and polychemotherapy

The role of syndecan and tenascine during tooth development. Review o the literature
No full textMorphogenesis and cell differentiation in the developing tooth are controlled by a series of reciprocal interactions between the epithelial and mesenchymal tissues. The exact molecular mechanisms operating in these interactions are unknown at present, but both structural components of the extracellular matrix and cellular receptors have been suggested to be involved. In this review we resume our knowledge about tenascin and syndecan distribution and activity
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
