Large-breast reconstruction using fat graft only after prosthetic reconstruction failure.
No full textBACKGROUND: When prosthetic reconstruction fails, and in the case of absolute contraindications to flaps use, no common reconstructive option is available. METHODS: A large irradiated breast was reconstructed using only fat grafts (9 sessions) after prosthetic reconstruction failure (exposure of implant) due to absolute contraindications to general anesthesia and unavailability of large flaps. During the first four sessions small volumes were implanted in the extremely rigid and retracted tissues with regenerative purposes. Larger volumes were implanted during the last five sessions to improve volume and shape. RESULTS: A pleasant aesthetic result was achieved. Tissue regeneration with good vascular support was evident at ultrasonography and magnetic resonance. Histologic and ultrastructural examination of the new tissue showed normal adipose tissue with cell and vasculostromal maturation aspects. No degenerative or inflammatory aspects were present. CONCLUSION: Fat graft transplantation can be a reliable and safe option for breast reconstruction in selected patients
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
