    Successful repair of complete sternal cleft associated with congenital heart disease. Report of one case

    Total failure of sternal fusion without other developmental anomalies of the chest and abdominal wall is rare. We report on a 52-year-old man with a total cleft sternum associated exclusively with an ostium secundum type atrial septal defect, a large cono-ventricular septal defect and pulmonary stenosis, who underwent successful surgical repair of the congenital heart disease and of the sternal anomaly by direct approximation of the freshened sternal remnants to the midline without interposition of tissue graft or inert prosthesis. This technique should be considered and attempted first as a better surgical option even in adult patients

    Primary cardiac leiomyosarcoma: seven-year survival with combined surgical and adjuvant therapy

    No full text
    Primary cardiac sarcomas constitute a rare entity that have been uniformly associated with poor long-term survival. A case of left atrial leiomyosarcoma involving the interatrial septum and the right atrial free wall and presenting with syncope and atrial fibrillation, is described. Two extensive surgical excisions followed by adjuvant radiation and chemotherapy improved survival with a good quality of life. This approach of combined surgical, medical and radiation therapy may offer better longterm outcome, since our patient is the longest survivor thus far reported

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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
