No full textTransfer of the anterior branch of the obturator nerve for femoral nerve reconstruction and preservation of motor function: A case report
No full textAbstract
INTRODUCTION: Femoral nerve lesions are uncommon but severely disrupting at the functional level, because of the inability to walk, run, and passing from sitting to standing position. Reconstruction via local nerve transfer (neurotization) is a relatively new yet promising procedure.
PRESENTATION OF CASE: We describe a case of successful restoration of rectus femoris' function after a malignant process by transfer of the anterior branch of the obturator nerve at the thigh level. At present, only few similar reports are present in the literature. Nerve gap after surgery was considerable (10 cm) and nerve grafting could have been unsatisfactory in terms of reinnervation. Therefore, reconstruction was managed with nerve isolation and transfer to the rectus femoris motor branch. The functional result was satisfactory at 1-year follow up with margins for further improvement.
DISCUSSION: This case reported favorable outcomes of neurotization of the anterior branch of the obturator nerve for femoral nerve lesion. Reports of success with this procedure are still limited, but the promising results in terms of functional recovery suggest it should be offered to patients as a viable therapeutic option.
CONCLUSION: Advantages of neurotization compared to grafts are several, including: limiting suturing sites and scarring; shortening the recovery time by decreasing the required regeneration distance; and allowing for faster muscle reinnervation. The choice to transfer the anterior branch of the obturator nerve specifically allows to preserve part of the adductor functionality in the thigh without affecting the stability of the knee joint.

Combining traditional and microsurgical reconstruction after a complex hand trauma with multiple tissue defects. A case report
Full text link: Complex injuries involving bones, tendons and soft tissues of the hand still represent a difficult challenge for reconstructive surgeons. Hereby, we present a case of a man suffering from a complex crush injury of the right hand that led to a wide three-dimensional defect with loss of two metacarpal bones, extensor tendons and skin. For composite hand defects, the most common surgical approach provides for a one-stage composite reconstruction or for an early restoration of bone and skin, with delayed tendon grafts. For the peculiarity of the defect, a one-stage reconstruction was not feasible. Hence, we opted for a two-stage reconstruction but the usual surgical steps have been inverted. First we secured tendon and skin restoration through a composite teno-cutaneous radial free flap. A month later, we reconstructed the two metacarpals with a modified Masquelet technique using fibular cortical graft. This strategy allowed the patient to start an early rehabilitation program and obtain a satisfactory recovery of his dominant hand.

Symmetrical peripheral gangrene reconstruction after lower limb amputation
No full textSymmetrical peripheral gangrene (SPG) is a complication of septicemia, characterized by progressive skin lesions, which can result in wide necrosis of all the extremities. Severe necrosis is often responsible of disfiguring consequences. It is important to limit the amputation and to provide a stable and functional soft tissue coverage of the stumps. Limited amputation and free flap reconstruction may help to prevent tissue loss and to provide an effective prosthetization and a prompt rehabilitation. We present a clinical case of a 60-year-old male admitted in our department for lower limbs necrosis due to SPG after a pneumococcal infection. The patient underwent bilateral forefeet amputation and microsurgical reconstruction with antero-lateral thigh flap was performed on the left stump. Vascular complications determined a progressive necrosis of the flap and the failure of the reconstruction. A careful analysis of the local and systemic inflammatory vascular and coagulative issues following the SPG has been performed to explain the failure of the microsurgery. Although the opinion of several authors is divided about the use of free tissue transfer, we believe that microsurgical reconstruction remains the first choice of treatment due to the reduced morbidity and early rehabilitation it provides.

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
Variations on the Author
Full text link“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
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Persistent Sciatic Artery and its role in limb salvage in oncological surgery
No full textThe Persistent Sciatic Artery (PSA) is a rare congenital anomaly due to missed involution of embryo-fetal sciatic artery, which is the main blood supply to lower limb during embryonic development until superficial femoral artery (SFA) is formed. The PSA is frequently related to complications in adults like aneurysm and embolism. Here we present a case in which the discovery of a complete PSA resulted limb saving. In case of oncologic or trauma surgery, when no other options are available, the PSA can help in management of reconstructive surgery
