Title: Laparoscopic Approach in Patient with Situs Inversus Totalis and Colelithiasis: a Case Report.
Background: Situs Inversus Totalis is a rare clinical condition that gives a mirror aspect to the position of the organs. It is a congenital condition and though it does not affect normal health or longevity, it may be a challenge in cases requiring surgical intervention.
Case: The authors report a case of cholelithiasis in a patient with previous diagnosis of Situs Inversus Totalis. The patient presented abdominal pain, related to eating and associated with nausea and vomiting. After the image exams, it was performed the surgical procedure, without intercurrences.
Conclusion:Situs Inversus Totalis is a challenge for surgical approach because of the mirrored configuration of the organs, which can lead to misdiagnosis. Using image exams anda complete evaluation of the patient helps the correct management in caso of surgical procedures, and consequently influence in the prognosis.
Thoracic Syndesmophytes Commonly Occur in the Absence of Lumbar Syndesmophytes in Ankylosing Spondylitis: A Computed Tomography Study
Authors: Tan Sovira , Yao Lawrence , Ward Michael M. 
Published: October 2017

Objective.To determine the extent of thoracic involvement with syndesmophytes in ankylosing spondylitis (AS) relative to lumbar involvement.Methods.We performed thoracolumbar spine computed tomography (CT) and lumbar radiography on 18 patients. We quantitated syndesmophytes in 11 intervertebral disc spaces and related these to the presence of syndesmophytes on lumbar radiographs.Results.Syndesmophytes were slightly more common in the thoracic than in the lumbar spine and bridging was significantly more common. Thoracic syndesmophytes were universally present in patients without visible lumbar syndesmophytes on either radiographs or CT.Conclusion.Syndesmophytes predominate in the thoracic spine. Lumbar radiographs underestimate the degree of thoracic involvement.
De l’intérêt heuristique du concept de « fantôme géographique » pour penser les régionalisations culturelles
Authors: von Hirschhausen Béatrice 
Published: October 2017

Le concept de « fantôme géographique », propose une réponse théorique à une série d’énigmes empiriques particulières, observables en Europe centrale et orientale. Les cas d’espèce dont il traite sont heuristiquement riches pour avancer sur la question de la production et de la reproduction dans la durée de différences entre des sociétés voisines et pour interroger plus généralement les phénomènes de différenciation géographique et de régionalisation à une échelle que les derniers développements de la géographie culturelle ont notoirement tendance à négliger, voire à récuser.
Le passage en revue du postcolonial
Authors: Collier Anne-Claire 
Published: October 2017

Cet article étudie six revues ayant publié un (ou deux) numéro(s) thématique(s) sur le postcolonial en 2006-2007. En adoptant un prisme circulatoire, nous souhaitons montrer que l’orientation de ces numéros (plus ou moins politique) est dépendante de l’identité de la revue et de la trajectoire des coordinateurs de ces numéros, la prise en compte des « traducteurs » dans une analyse de circulation internationale des idées est essentielle pour comprendre les distorsions et les retraductions que connaissent ces idées. Nous argumenterons finalement que ces numéros thématiques ont peu à voir avec la circulation des auteurs classiques du postcolonial mais correspondent plutôt à une repolitisation de l’espace intellectuel français au lendemain de l’année 2005.
L’institutionnalisation de domaines d’études pluridisciplinaires autour de 68
Authors: Dormoy-Rajramanan Christelle 
Published: October 2017

Cet article propose une analyse socio-historique de demandes et offres d’institutionnalisation de domaines d’études pluridisciplinaires dans l’enseignement supérieur et la recherche, au cours des années 1950-1970. En étudiant, d’abord, les débats relatifs à la politique de la science et de l’enseignement supérieur et les acteurs qui y ont pris une part active (responsables politiques et administratifs, patronat, enseignants-chercheurs, étudiants), apparaissent des intérêts économiques, savants et militants comme ressorts de l’injonction croissante à la « pluridisciplinarité ». Cette dernière figure parmi les revendications majeures de la mobilisation universitaire de mai-juillet 1968, présentée comme une condition de l’amélioration de la formation des étudiants et du renouvellement des savoirs, d’un point de vue épistémologique et/ou « critique ». Entérinée par la loi Faure de 1968, la « pluridisciplinarité » constitue l’un des trois piliers de la refondation des universités dans l’après-68 et une institution telle que l’université de Paris VIII-Vincennes aura notamment pour prérogative de l’expérimenter, avec des usages entre science et militantisme qui ont contribué à la construction et l’évolution de certains savoirs, notamment relatifs aux femmes.

La tutoría es una herramienta útil en el proceso de enseñanza-aprendizaje universitario, aunque su desarrollo se ve dificultado en las aulas masificadas. Con este estudio se ha pretendido potenciar esta función tutorial en una asignatura en la que concurre esta circunstancia, con el fin de mejorar el rendimiento académico del alumnado. Para ello, se ha implementado un programa de tutorías en línea en la asignatura de “Microbiología e Inmunología” del Grado en Veterinaria de la Universidad de León, mediante la plataforma virtual Moodle. Cuarenta estudiantes se incorporaron voluntariamente (25% de la matrícula) al estudio, en menos de un día. Se elaboraron tres cuestionarios de quince preguntas sobre la materia impartida, con el objetivo de fomentar el trabajo del estudiante. Finalizado el periodo de resolución establecido, los estudiantes obtenían automáticamente la calificación y las respuestas correctas. Posteriormente, se habilitaban tres días para aclarar dudas mediante correo electrónico. Además, se realizaron encuestas para conocer el grado de satisfacción de los alumnos. El porcentaje de estudiantes tutelados (95,2%) que se presentó al examen final fue significativamente mayor que en los no tutelados (74,8%), hecho que también se observó en la proporción de aprobados (60,0 vs. 43,1%). La calificación numérica fue mayor entre los participantes, duplicando igualmente el porcentaje de los que obtuvieron la calificación de “sobresaliente” (2,7 vs. 1,1%). Además, el 87,5% de los participantes se mostró satisfecho con esta metodología docente. A partir de estos resultados se puede concluir que las tutorías en línea constituyen una herramienta útil que facilita el seguimiento de los alumnos, mejora su rendimiento académico y aumenta su motivación, recomendándose su aplicación en asignaturas con un elevado número de alumnos.
Collaboration challenges in systematic reviews: a survey of health sciences librarians
Authors: Nicholson Joey , McCrillis Aileen , Williams Jeff D. 
Published: October 2017

Objective: While many librarians have been asked to participate in systematic reviews with researchers, often these researchers are not familiar with the systematic review process or the appropriate role for librarians. The purpose of this study was to identify the challenges and barriers that librarians face when collaborating on systematic reviews. To take a wider view of the whole process of collaborating on systematic reviews, the authors deliberately focused on interpersonal and methodological issues other than searching itself.Methods: To characterize the biggest challenges that librarians face while collaborating on systematic review projects, we used a web-based survey. The thirteen-item survey included seventeen challenges grouped into two categories: methodological and interpersonal. Participants were required to indicate the frequency and difficulty of the challenges listed. Open-ended questions allowed survey participants to describe challenges not listed in the survey and to describe strategies used to overcome challenges.Results: Of the 17 challenges listed in the survey, 8 were reported as common by over 40% of respondents. These included methodological issues around having too broad or narrow research questions, lacking eligibility criteria, having unclear research questions, and not following established methods. The remaining challenges were interpersonal, including issues around student-led projects and the size of the research team. Of the top 8 most frequent challenges, 5 were also ranked as most difficult to handle. Open-ended responses underscored many of the challenges included in the survey and revealed several additional challenges.Conclusions: These results suggest that the most frequent and challenging issues relate to development of the research question and general communication with team members. Clear protocols for collaboration on systematic reviews, as well as a culture of mentorship, can help librarians prevent and address these challenges.

Published: October 2017

Purpose: To evaluate the outcome of combined Ahmed glaucoma valve (AGV) and phacoemulsification with posterior chamber intraocular lens implantation under infliximab in refractory uveitic glaucoma (UG). Methods: In this prospective interventional case series, 26 eyes of 26 patients with refractory UG underwent surgery under intravenous infliximab. The success rate was defined as intraocular pressure (IOP) 5 to 21 mm Hg with or without antiglaucoma medications (AGM), without additional glaucoma surgical intervention. Results: The mean IOP (37.8 ± 11.86 to 12.2 ± 2.8 mm Hg; p<0.0001) and mean number of AGM (3.4 ± 1.2 to 0.4 ± 0.1; p<0.001) were significantly reduced after surgery at 2 years. Kaplan-Meier survival analysis showed a cumulative probability of success for IOP control of 92% at 2 years of follow-up. Conclusions: Combined AGV and phacoemulsification is an effective treatment for controlling refractory UG with complicated cataract under infliximab.

Authors: Antonietta Blasi Maria , Maceroni Martina , Grazia Sammarco Maria , Pagliara Monica M. 
Published: October 2017

Background: Traditionally, surgical excision has been the treatment of choice for ocular surface squamous neoplasia (OSSN). Recurrences after surgery are high. To reduce the risk of recurrence, adjuvant therapies have been increasingly used. Purpose: We compared recurrences and complications of 3 forms of treatment for OSSN: surgical excision (group A), surgical excision plus adjuvant topical mitomycin C (MMC) (group B), and surgical excision plus subconjunctival interferon-α-2b (IFN-α-2b) (group C). Methods: A retrospective comparative study was conducted between January 2006 and March 2016 at the Ocular Oncology Service of the Catholic University of Rome. Seventy-nine patients with a confirmed histological diagnosis of OSSN were included: 43 were treated with surgical excision (group A), 16 underwent surgical excision plus topical MMC (group B), and 20 underwent surgical excision plus adjuvant subconjunctival IFN-α-2b (group C). Results: The recurrences were different in the 3 groups. Thirty-one recurrences (72%) were seen in group A, 5 (31%) were found in group B, and 3 (15%) were seen in group C. Eight (50%) patients who received MMC 0.02% complained of ocular discomfort, 10 (62.5%) presented conjunctival hyperemia, while conjunctival chemosis and corneal epitheliopathy were noticed in 2 (13%) and 2 (13%) patients, respectively. All patients treated with subconjunctival IFN-α-2b reported flu-like symptoms. Two patients (10%) complained of ocular discomfort. Conclusions: Our study revealed that OSSN is not always manageable with simple excision. Adjuvant chemotherapy is strongly advisable after surgery to reduce recurrences. Interferon injections and MMC drops are effective in preventing recurrences and should be administered after surgery.

Published: October 2017

Purpose: Classical or temporal internal limiting membrane (ILM) flap transposition with air or gas tamponade are current trends with the potential to improve surgical results, especially in cases with large macular holes. Methods: A prospective case series included patients with idiopathic macular holes or persistent macular holes after 23-G pars plana vitrectomy (PPV) and ILM peeling with gas tamponade. In all patients, 23-G PPV and ILM peeling with ILM flap transposition with gas tamponade and postoperative face-down position was performed. Results: In 7 of 9 eyes, temporal ILM flap transposition combined with pedicle ILM flap could be successfully performed and macular holes were closed in all eyes after surgery. The remaining 2 eyes were converted to pedicle ILM flap transposition with macular hole closure after surgery. Three eyes were scheduled as pedicle ILM flap transposition due to previous ILM peeling. In 2 of these eyes, the macular hole could be closed with pedicle ILM flap transposition. In 3 eyes, free ILM flap transposition was performed and in 2 of these eyes macular hole could be closed after surgery, whereas in 1 eye a second surgery, performed as pedicle ILM flap transposition, was performed and led to successful macular hole closure. Conclusions: Use of ILM flaps in surgical repair of macular hole surgery is a new option of treatment with excellent results independent of the diameter of macular holes. For patients with persistent macular holes, pedicle ILM flap transposition or free ILM flap transposition are surgical options.

Published: October 2017

Purpose: To compare the inverted flap and the subretinal aspiration technique for full-thickness macular hole (FTMH) surgery. Methods: Forty consecutive eyes with a stage IV FTMH were randomly assigned into 2 treatment groups. After core vitrectomy and perimacular internal limiting membrane (ILM) peeling, in group A, the subretinal remnant macular fluid was aspirated with a 41-G cannula after the air-fluid exchange procedure, while in group B, the technique of an inverted ILM flap was completed. Differences in postoperative best-corrected visual acuity (BCVA) and occurrence of intraoperative or postoperative complications between the 2 groups were evaluated. Results: All FTMHs were closed after the first surgery with no intraoperative or postoperative complications. In group A, 16 patients (80%) showed improvement of BCVA and 4 (20%) showed stabilization. In group B, 12 patients (60%) had improved BCVA, while 6 (30%) remained stable and 2 (10%) worsened. Postoperative BCVA for group A was significantly better than for group B (p = 0.022). Conclusions: The surgical techniques had similar rates of closure of FTMH, although BCVA outcomes were significantly better in the subretinal aspiration group.

Published: October 2017

Introduction: Hip abductor tendon (HAT) tearing is commonly implicated in greater trochanteric pain syndrome. Surgical studies are often reported in small cohorts and with limited information on functional improvement. This study reports the clinical and functional outcomes after HAT repair. Methods: 112 patients with symptomatic HAT tears, diagnosed via magnetic resonance imaging, underwent open bursectomy, V-Y lengthening of the iliotibial band, debridement of the diseased tendon, decortication of the trochanteric foot-plate and reattachment of the tendon with suture anchors, augmented with a LARS ligament through a trans-osseous tunnel. Patients were evaluated pre-surgery and at 3, 6 and 12 months post-surgery using the Harris (HHS) and Oxford (OHS) Hip Scores, SF-12, hip range of motion, 6-minute walk and 30-second single leg stance tests. Maximal isometric hip abduction strength (HAS) was assessed and limb symmetry indices (LSIs) were calculated between the operated and non-operated limbs. Patient satisfaction and perceived global rating of change (GRC) was evaluated. Analysis of variance evaluated improvement over time. Results: There was a significant improvement (p<0.05) in all clinical and functional measures. HAS significantly improved over time (p<0.002) and all LSIs were >85% at 12 months. At 12 months, a mean GRC score of 3.5 (range -1 to 5) was reported, while 96% of patients were satisfied with their surgical outcome. There was a 2.7% (n = 3) failure rate at 12 months. Conclusions: HAT reconstruction, augmented with a synthetic ligament, demonstrated significantly improved clinical and functional outcomes, high levels of patient satisfaction and a low failure rate to 12 months post-surgery.
Analysis of mandibular changes using panoramic-based indices in patients with chronic renal failure
Authors: Secgin Cansu K. , Kulah Cemal K. , Gulsahi Ayşe 
Published: October 2017

Introduction: Chronic renal failure (CRF) is a progressive disease affecting many systems and causing dental and periodontal problems, in particular a decrease or loss in the amount of cortical bone that is visible on radiographs. Panoramic radiography is useful for determining these changes. The aim of this study was to evaluate cortical parts of the mandible using panoramic-based indices in patients with CRF. Methods: 70 subjects with CRF were included in the study. The measurements of panoramic indices were made according to the visibility (mandibular cortical index, MCI) and thickness (mental index, MI) of the inferior cortex of the mandible. Then, these indices, obtained from 70 healthy controls of the same age and gender, were assessed and the results were compared. The effects of dental status and hemodialysis duration on MCI and MI were also investigated. Results: The frequency of an eroded cortex was significantly elevated in patients with CRF (p<0.05). The mean MI was lower in patients with CRF than in healthy subjects (5.53 ± 1.62 and 5.73 ± 1.31 mm, respectively), but the difference was not statistically significant (p>0.05). No correlation was found between hemodialysis duration and mandibular indices (p>0.05). Dental status was not associated with mandibular indices (p>0.05). Conclusions: These results suggest that MCI might be a useful radiographic parameter for evaluating changes occurring in the cortical parts of the mandible in CRF patients. Clinicians should be aware of these changes while planning invasive dental treatments in CRF patients.
