Infezione da actinomiceti in un odontoma composto
No full textIntroduction. Compound odontoma is an abnormal development of dental tisssue which is characterized by regular and ordinate structures that resemble a normal tooth. Actinomyces is an abnormal inhabitant of the oral cavity which is able to become pathological whenever the specific or non specific defense mechanisms of an individual may fail. Materials and methods. Described is a case of 60 years old male with no deficit of his immune system confirmed by various analysis. There is one year history of an intermittent pain to the left half of his mandible. An x-ray suggests an odontoma. The gengiva, near the lesion, appears to be ulcerated; two fistulous tracts with the oral mucosa and one with the skin area are seen. After decalcification the tissue obteined from the lesion has been fixed in formalin and included in paraffine. The slides were stained with Haematoxilin-Eosin, PAS and Grocott's silver method. Results. The lesion consists of well differentiated enamel and dentin including a fragment of the pulp featuring the typical aspects of compound odontoma. In addition the pulp shows an intense infiltration of granulocytes, plasma cells and numerous capillaries; around the pulp an extensive area of necrosis is present, in which there are eosinophilic aggregates of amorphic and granular matrix suggestive of an infection by actinomyces. This was confirmed with PAS and by an intense argyrophilia. Conclusion. Described is a case of compound odontoma complicated by an actinomycosis infection in a patient with a well functioning immune system which appears to be the first case reported in the literature, to the best of our knowledge

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

Small-cell osteosarcoma of the mandible. Case report
No full textA case of small-cell osteosarcoma of the mandible in an 8-year-old girl is reported. This unusual variant may simulate Ewing's sarcoma and other small-cell neoplasms affecting jaws in children. The correct recognition of this type of tumor may be important for an appropriate choice of treatment
