No full textThe curious case of a massive right heart thrombosis: A case report
Full text linkBackground Intraventricular masses are a relatively rare condition ranging from asymptomatic to potentially life-threatening situations. Case summary Herein, we report a case of a 49-year-old woman under investigation for a massive right ventricular (RV) mass who underwent complete investigation for possible differential diagnosis, in the suspect of RV tumour. Multimodality imaging with cardiac computed tomography and magnetic resonance imaging showed the presence of a massive thrombus partially obliterating the right ventricle. Surgical removal of the mass showed a large area of stratified thrombosis with an underlying area of endocardial fibrosis. The patient has been then discharged in good clinical condition and with lifetime oral anticoagulation. Discussion Massive RV thrombosis is a rare yet potentially fatal condition. Invasive management is preferable and lifetime anticoagulation is required to reduce possible downstream thrombotic complications
RARE CASE OF SOLITARY BONE CYST OF THE UPPER JAW: A CASE REPORT
No full textAim: this case report describes the diagnostic process and the surgical treatment of a solitary bone cyst of the maxilla. In ad- dition, we aimed to verify the bone healing of the surgical site supported by PRF (platelet-rich fibrin), 12 months after the enucleation of the lesion.
Methods: a 59-year-old patient, with no significant systemic pathologies, came to our attention with a large osteolytic le- sion of the upper jaw. Surgical enucleation of the lesion was performed under general anesthesia, followed by primary wound closure of the access flaps.
The residual cavity was filled with PRF from a sample of the patient’s blood.
Results: the postoperative course was uneventful, without si- gnificant complications. After 12 months, a three-dimensional radiographic evaluation showed complete restoration of bone architecture in the surgical site and no sign of recurrence of the lesion. Pulp vitality was preserved for all the elements adjacent to the enucleated lesion.
Conclusions: the outcomes of this clinical case suggest that the clot formation, the support of both the flap and the clot with palatal plate, and the enrichment of the clot with PRF pro- mote good healing and re-ossification of bone cavities, even after enucleation of large lesions. Noteworthy is also the rarity of the location of the solitary cyst
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
