    Pre-expanded anterollateral thigh perforator flap for phallioplasty

    No full text
    The anterolateral thigh (ALT) perforator flap for phalloplasty is gaining popularity because it avoids the well-known scars of the radial forearm flap. However, scars are not eliminated, just moved to a different location, the thigh, that can for some patients be of great sexual value. Preexpansion of the ALT flap allows primary donor site closure, thus avoiding not only the unsightly appearance of a skin grafted ALT donor site, but also the skin graft donor site scar. Preoperative perforator location by means of computed tomography angiography allows safe expander placement through 2 small remote incisions

    Bilateral DIEP Flap Breast Reconstruction to a Single Set of Internal Mammary Vessels: Technique, Safety, and Outcomes after 250 Flaps

    BACKGROUND: The deep inferior epigastric artery perforator (DIEP) flap is considered the gold standard in autologous breast reconstruction. In bilateral cases, both flaps are often anastomosed to the internal mammary vessels on either side of the sternum. The authors propose a method in which both flaps are anastomosed to only the right side internal mammary artery and vein. METHODS: Between November of 2009 and March of 2018, 125 patients underwent bilateral DIEP flap breast reconstruction with this technique. One flap is perfused by the anterograde proximal internal mammary artery and the second one by the retrograde distal internal mammary artery after presternal tunneling. Patient demographics and operative details were reviewed retrospectively. RESULTS: Two hundred fifty flaps were performed. One hundred fifty-two flaps were prophylactic or primary reconstructions (60.8 percent), 70 were secondary reconstructions (28 percent), and 28 were tertiary reconstructions (11.2 percent). Mean patient age was 46 years, and the mean body mass index was 25 kg/m. Sixty patients underwent radiation therapy or chemotherapy (48 percent). The authors encountered one significant partial failure (0.4 percent) and nine complete flap failures (3.6 percent). The authors did not see a statistically significant predisposition for failure comparing the retrograde with the anterograde flow flaps, nor when comparing the tunneled with the nontunneled flaps. CONCLUSIONS: The authors' results show that anastomosing both DIEP flaps to a single set of mammary vessels is safe and reliable. The authors conclude that the retrograde flow through the distal internal mammary artery is sufficient for free flap perfusion and that subcutaneous tunneling of a free flap pedicle does not predispose to flap failure.

    Variations on the Author

    No full text
    “Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship

    Also By The Same Author: AKTiveAuthor, a Citation Graph Approach to Name Disambiguation

    No full text
    The desire for definitive data and the semantic web drive for inference over heterogeneous data sources requires co-reference resolution to be performed on those data. In particular, name disambiguation is required to allow accurate publication lists, citation counts and impact measures to be determined. This paper describes a graph-based approach to author disambiguation on large-scale citation networks. Using self-citation, co-authorship and document source analyses, AKTiveAuthor clusters papers, achieving precision of 0.997 and recall of 0.818 over a test group of eight surname clusters

    John F. Kennedy telegram to Roosevelt

    No full text
    Jersey Homesteads (later the Borough of Roosevelt) was established in the 1930s as an agro-industrial cooperative community. It was established specifically for urban Jewish garment workers, many of whom had emigrated from Europe. President John F. Kennedy sent a telegram to the citizens of Roosevelt, New Jersey, apologizing for not being able to attend the memorial dedication in honor of former President Franklin Delano Roosevelt. (Jersey Homesteads became Roosevelt in 1945 in honor of the president.) President Kennedy expressed his gratitude to the people of Roosevelt for constructing the memorial, and commented that it will serve as a constant reminder of Roosevelt's good works

    Logarithmic variance profiles and the corresponding f-1 spectra of temperature fluctuations in turbulent Rayleigh-Bénard convection

    We report experimental results for the temperature variance 2(z) and the corresponding frequency spectra P(f) in turbulent Rayleigh-Bénard convection (RBC) in a cylindrical sample of aspect ratioT= D/L = 1:00 (D = 1:12 m is the diameter and L = 1:12 m the height). The measurements were conducted in the Rayleigh-number range 1011 < Ra < 1:35 1014 and Pr ' 0:8. For Ra = 1:35x1014, 2(z) could be described well by a logarithmic dependence on the vertical position z in a range of z 1 < z < z 2 with z 1 ' 70 and z 2 = 0:1L. Here L=(2Nu) is the thickness of a thin thermal sublayer adjacent to the horizontal plate where the heat flux (denoted by the Nusselt number Nu) is carried mostly by thermal diffusion. In the log layer, we found that the temperature spectra had a significant frequency range over which P(f) f with close to 1. As Ra decreased, increased so that the log layer became thinner. At Ra = 2:05 1011, z 2 < z 1 and therefore there was no range for a log layer. Correspondingly, the temperature spectrum near the horizontal plate did not have the f1 scaling form either

    Mapping the Discipline of the Olympic Games An Author-Cocitation Analysis

    No full text
    The authors conducted an author cocitation analysis on prominent authors writing about the Olympics during the 1990s. Author cocitation is an established bibliometric technique that can be used to measure the relative similarities of topics written about by the cited authors. This enables a visual representation of the “intellectual space” of the discipline, in this case the Olympics, to be created for the period under review. So core and peripheral research areas are identified, along with their major contributors. The representation appears as a two-dimensional cluster-enhanced map. Subject expertise was then applied to the results to place labels on the generated clusters of authors and their topics
