Authors: Ull Christopher , Seybold Dominik , Königshausen Matthias , Schildhauer Thomas , Geßmann Jan 
Published: April 2018

Traumatic knee joint dislocations belong to the most serious injuries of the lower extremity with a high rate of neurovascular injuries, soft tissue injuries and compartment syndromes. The aim of the study was to determine the long-term results of patients with traumatic knee joint dislocations after conservative and operative treatment of the ligaments. In addition, differences between the two therapies were investigated and what kind of incidents and complications occurred. All patients with traumatic knee joint dislocation were included over a time period of 25 years (1990 to 2014). 119 patients with 121 traumatic knee joint dislocations were hospitalized during this time. A conservative treatment of the ligaments was performed in 48 knee joint dislocations (39.7%) and an operative treatment in 73 injuries (60.3%). After an average follow-up of 10.9 ± 6.7 years, 38 patients with 39 knee joint dislocations were examined. Significance was set to p < 0.05. Patients with operative ligament care showed significantly better flexion compared to patients with conservative treatment of the ligaments (p < 0.033). A median of 76 points (range 34 - 100 points) was achieved in the Lysholm score. 56.2 points (range 45.3 - 71.1 points) were achieved in the SF-36 mental health score and 43.7 points (range 21.2 - 59.6 points) in the SF-36 physical heatlh score. The subjective part of the IKDC 2000 showed a median score of 60.9 points (range 32.1 - 97.7 points). Patients with operative ligament care showed better results in the scores, however, without achieving any significance.Posttraumatic arthrosis was found in 47% of all radiologically-re-examined patients in the Kellgren-Lawrence score. The long-term results showed a satisfactory knee function with physical limitations in the health-related quality of life. However, a reduced range of motion as well as a posttraumatic osteoarthritis of the affected knee joint often appeared, which was independent of the therapy strategy. Patients with operative ligament care showed better results in the scores without any significane, but achieved a significantly better flexion than patients with conservative treatment of the ligaments.
Designs for the Pluriverse
Authors: Escobar Arturo 
Published: April 2018

In Designs for the Pluriverse Arturo Escobar presents a new vision of design theory and practice aimed at channeling design's world-making capacity toward ways of being and doing that are deeply attuned to justice and the Earth. Noting that most design—from consumer goods and digital technologies to built environments—currently serves capitalist ends, Escobar argues for the development of an “autonomous design” that eschews commercial and modernizing aims in favor of more collaborative and placed-based approaches. Such design attends to questions of environment, experience, and politics while focusing on the production of human experience based on the radical interdependence of all beings. Mapping autonomous design’s principles to the history of decolonial efforts of indigenous and Afro-descended people in Latin America, Escobar shows how refiguring current design practices could lead to the creation of more just and sustainable social orders.

Antibodies against pathogens provide information on exposure to infectious agents and are meaningful measures of past and present infection. Antibodies were measured in the plasma of children that are the offspring in a population-based birth cohort, the Avon Longitudinal Study of Parents and Children (ALSPAC). Plasma was collected during clinics at age 5, 7, 11 and 15 years. The antigens examined include: fungal (Saccharomyces cerevisiae); protozoan (Toxoplasma gondii and surface antigen 1 of T. gondii); herpes viruses (cytomegalovirus, Epstein-Barr virus, herpes simplex virus type 1); common colds (influenza virus subtypes H1N1 and H3N2); other antigens (measles); animal (feline herpes virus, Theiler’s virus); bacteria (Helicobacter pylori); dietary antigens (bovine casein alpha protein, bovine casein beta protein). Alongside the depth of data available within the ALSPAC cohort, this longitudinal resource will enable the investigation of the association between infections and a wide variety of outcomes.

Digitehnoloogia on kujunenud hariduse osaks alates lasteaiast ning ka kutsestandardis on koolieelse lasteasutuse õpetaja läbiva pädevusena sätestatud digipädevus. Paljud lasteaiaõpetajad on aga õppinud ajal, mil digitehnoloogia polnud veel õppekavas. Artikli eesmärk on selgitada ja võrrelda lasteaiaõpetajate ning kooli eelse lasteasutuse õpetajaks õppivate üliõpilaste hinnanguid oma aine-, pedagoogika- ja tehnoloogiateadmistele TPACKi raamistikust lähtudes.

Published: April 2018

Este artigo – teórico – problematiza as noções de educação online (EOL), desenho didático em ambiências híbridas-formativas, formação, autoria e docência, a partir da cena sociotécnica emergente conectada em rede, que denominamos de cibercultura. Apostamos na EOL como um dos fenômenos da cultura contemporânea em rede, discutindo os desdobramentos de suas fases e de seus fundamentos e tencionando que essa modalidade de ensino exige metodologia própria, práticas educativas contextualizadas e docência voltada para a interatividade e colaboração. Por fim, partimos do pressuposto que o papel da docência é fundamental na EOL, ela é responsável não só pelo processo de mediação entre o objeto a ser conhecido e os/as cursistas, como também por todo o processo formativo, atuando nas problematizações em sala de aula, promovendo autorias e partilhas de experiências e na ampliação dos reportórios culturais e de conhecimentos.
O envolvimento de médicos legistas do Rio de Janeiro com as torturas durante a ditadura civil-militar de 1964-1985
Authors: Carneiro Mauro Brandão 
Published: April 2018

Este artigo analisa os trâmites e os desfechos de processos ético-profissionais no Conselho Regional de Medicina do Estado do Rio de Janeiro (CREMERJ) que envolveram médicos legistas denunciados pelo Grupo Tortura Nunca Mais, acusados de emitir laudos falsos de militantes assassinados sob tortura, laudos esses que na verdade confirmavam a versão oficial da repressão: mortos por “atropelamento”, “tiroteio” ou “suicídio”. O levantamento mostra que a maioria destes processos foi arquivada por prescrição. A discussão aborda esta temática sob a ótica de que crimes como participação ou conivência com a tortura deveriam ser imprescritíveis, confrontando com o arcabouço jurídico vigente.

Authors: Lauthe O. , Soubeyrand M. , Babinet A. , Dumaine V. , Anract P. , Biau D. J. 
Published: April 2018

Aims The primary aim of this study was to determine the morbidity of a tibial strut autograft and characterize the rate of bony union following its use. Patients and Methods We retrospectively assessed a series of 104 patients from a single centre who were treated with a tibial strut autograft of > 5 cm in length. A total of 30 had a segmental reconstruction with continuity of bone, 27 had a segmental reconstruction without continuity of bone, 29 had an arthrodesis and 18 had a nonunion. Donor-site morbidity was defined as any event that required a modification of the postoperative management. Union was assessed clinically and radiologically at a median of 36 months (IQR, 14 to 74). Results Donor-site morbidity occurred in four patients (4%; 95% confidence interval (CI) 1 to 10). One patient had a stress fracture of the tibia, which healed with a varus deformity, requiring an osteotomy. Two patients required evacuation of a haematoma and one developed anterior compartment syndrome which required fasciotomies. The cumulative probability of union was 90% (95% CI 80 to 96) at five years. The type of reconstruction (p = 0.018), continuity of bone (p = 0.006) and length of tibial graft (p = 0.037) were associated with the time to union. Conclusion The tibial strut autograft has a low risk of morbidity and provides adequate bone stock for treating various defects of long bones. Cite this article: Bone Joint J 2018;100-B:667–74.

Published: April 2018

AimsThe aim of this study was to identify the association between asymmetrical skin creases of the thigh, buttock or inguinal region and pathological developmental dysplasia of the hip (DDH).Patients and MethodsBetween 1 January 1996 and 31 December 2016, all patients referred to our unit from primary or secondary care with risk factors for DDH were assessed in a “one stop” clinic. All had clinical and sonographic assessment by the senior author (RWP) with the results being recorded prospectively. The inclusion criteria for this study were babies and children referred with asymmetrical skin creases. Those with a neurological cause of DDH were excluded. The positive predictive value (PPV) for pathological DDH was calculated.ResultsA total of 105 patients met the inclusion criteria. There were 71 girls and 34 boys. Only two were found to have pathological DDH. Both also had unilateral limited abduction of the hip in flexion and a positive Galeazzi sign with apparent leg-length discrepancy. Thus, if the specialist examination of a patient with asymmetrical skin creases was normal, the PPV for DDH was 0%.ConclusionIsolated asymmetrical skin creases are an unreliable clinical sign in the diagnosis of pathological DDH. Greater emphasis should be placed on the presence of additional clinical signs to guide radiological screening in babies and children. Cite this article: Bone Joint J 2018;100-B:675–9.

Authors: Davda K. , Heidari N. , Calder P. , Goodier D. 
Published: April 2018

AimsThe management of a significant bony defect following excision of a diaphyseal atrophic femoral nonunion remains a challenge. We present the outcomes using a combined technique of acute femoral shortening, stabilized with a long retrograde intramedullary nail, accompanied by bifocal osteotomy compression and distraction osteogenesis with a temporary monolateral fixator.Patients and MethodsEight men and two women underwent the ‘rail and nail’ technique between 2008 and 2016. Proximal locking of the nail and removal of the external fixator was undertaken once the length of the femur had been restored and prior to full consolidation of the regenerate.ResultsThe mean lengthening was 7 cm (3 to 11). The external fixator was removed at a mean of 127 days (57 to 220). The mean bone healing index was 28 days/cm and the mean external fixation index was 20 days/cm (11 to 18). There were no superficial or deep infections.ConclusionThis small retrospective study shows encouraging results for a combined technique, enabling compression of the femoral osteotomy, alignment, and controlled lengthening. Removal of the fixator and proximal locking of the nail reduces the risk of complications and stabilizes the femur with the maximum working length of the nail.

Published: April 2018

Aims The aim of this study was to evaluate antegrade autologous bone grafting with the preservation of articular cartilage in the treatment of symptomatic osteochondral lesions of the talus with subchondral cysts. Patients and Methods The study involved seven men and five women; their mean age was 35.9 years (14 to 70). All lesions included full-thickness articular cartilage extending through subchondral bone and were associated with subchondral cysts. Medial lesions were exposed through an oblique medial malleolar osteotomy, and one lateral lesion was exposed by expanding an anterolateral arthroscopic portal. After refreshing the subchondral cyst, it was grafted with autologous cancellous bone from the distal tibial metaphysis. The fragments of cartilage were fixed with 5-0 nylon sutures to the surrounding cartilage. Function was assessed at a mean follow-up of 25.3 months (15 to 50), using the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot outcome score. The radiological outcome was assessed using MRI and CT scans. Results The mean AOFAS score improved from 65.7 (47 to 81) preoperatively to 92 (90 to 100) at final follow-up, with 100% patient satisfaction. The radiolucent area of the cysts almost disappeared on plain radiographs in all patients immediately after surgery, and there were no recurrences at the most recent follow-up. The medial malleolar screws were removed in seven patients, although none had symptoms. At this time, further arthroscopy was undertaken, when it was found that the mean International Cartilage Repair Society (ICRS) arthroscopic score represented near-normal cartilage. Conclusion Autologous bone grafting with fixation of chondral fragments preserves the original cartilage in the short term, and could be considered in the treatment for adult patients with symptomatic osteochondral defect and subchondral cysts.

Published: April 2018

Aims Although we often encounter patients with an aortic aneurysm who also have diffuse idiopathic skeletal hyperostosis (DISH), there are no reports to date of an association between these two conditions and the pathogenesis of DISH remains unknown. This study therefore evaluated the prevalence of DISH in patients with a thoracic aortic aneurysm (AA). Patients and Methods The medical records of 298 patients who underwent CT scans for a diagnosis of an AA or following high-energy trauma were retrospectively examined. A total of 204 patients underwent surgery for an AA and 94 had a high-energy injury and formed the non-AA group. The prevalence of DISH was assessed on CT scans of the chest and abdomen and the relationship between DISH and AA by comparison between the AA and non-AA groups. Results The prevalence of DISH in the AA group (114/204; 55.9%) was higher than that in the non-AA group (31/94; 33.0%). On multivariate analysis, the factors of AA, male gender, and ageing were independent predictors of the existence of DISH, with odds ratios of 2.9, 1.9, and 1.03, respectively. Conclusion This study revealed that the prevalence of DISH is higher in patients with an AA than in those without an AA, and that the presence of an AA significantly influenced the prevalence of DISH.

In defence of the posterior malleolus
Authors: White T. O. 
Published: April 2018

The posterior malleolus of the ankle is the object of increasing attention, with considerable enthusiasm for CT scanning and surgical fixation, as expressed in a recent annotation in The Bone & Joint Journal. Undoubtedly, fractures with a large posterior malleolar fragment that allow posterior talar subluxation from the mortise are served better by fixation. However, in all other situations, the existing literature does not support this widespread change in practice. The available biomechanical evidence shows that the posterior malleolus has little part to play in the stability or contact stresses of the ankle joint. Radiographic studies have not shown that CT scanning offers helpful information on pathoanatomical classification, case selection, or prognosis, or that scanning improves the likelihood of an adequate surgical reduction. Clinical studies have not shown any improvement in patient outcome after surgical fixation, and have confirmed that the inevitable consequence of increased intervention is an increased rate of complications. A careful and thoughtful evaluation of indications, risks, and benefits of this fashionable concept is required to ensure that we are deploying valuable resources with efficacy, and that we do no harm.

Some More Notes on Siderits and Katsura’s Translation of Nāgārjuna’s Mūlamadhyamakakārikā
Authors: Ferraro Giuseppe 
Published: April 2018

Abstract
In my recent translation (Ferraro 2016) from Sanskrit to Portuguese of Nāgārjuna’s Mūlamadhyamakakārikā I have frequently consulted, among many others, Mark Siderits and Shōryū Katsura’s English version (Siderits / Katsura 2013) of the same work. In this review article I present some places where my understanding of Nāgārjuna’s words more markedly diverges from their translation. Regarding the ideal of “an English-speaking Nāgārjuna” as a work-in-progress which could be constantly improved, my observations aim to continue the list of remarks presented by Anne MacDonald in her review article (MacDonald 2015) of Siderits and Katsura’s work.
HCV core antigen comes of age: a new opportunity for the diagnosis of hepatitis C virus infection
Authors: Galli Claudio , Julicher Paul , Plebani Mario 
Published: April 2018

Abstract
The diagnosis of hepatitis C virus (HCV) infection has been traditionally based on the detection of the host antibody response. Although antibody assays are available in different formats and are fairly accurate, they cannot distinguish between an ongoing infection with HCV replicative activity and a past infection where HCV has been cleared, spontaneously or after a successful therapy. As a chronic infection is mostly asymptomatic until the late clinical stages, there is a compelling need to detect active HCV infection by simple and reproducible methods. On this purpose, the clinical guidelines have suggested to search for the HCV ribonucleic acid (HCV-RNA) after anti-HCV has been detected, but this second step carries several limitations especially for population screening. The availability of fast and automated serological assays for the hepatitis C core antigen (HCVAg) has prompted an update of the guidelines that now encompass the use of HCVAg as a practical alternative to HCV-RNA, both for screening and monitoring purposes. In this paper, we summarize the features, benefits and limitations of HCVAg testing and provide an updated compendium of the evidences on its clinical utility and on the indications for use.

Abstract
Three azocalix[4]arenes with distal ethyl ester residues, 5-phenylazo-25,26,27-tris[(ethoxycarbonyl)methoxy]-28-hydroxycalix[4]arene (2), 5-(o-methylphenyl)azo-25,26,27-tris[(ethoxycarbonyl)methoxy]-28-hydroxycalix[4]arene (3), 5-(p-Methylphenyl)azo-25,26,27-tris[(ethoxycarbonyl)methoxy]-28-hydroxycalix[4]arene (4), were synthesized and their binding properties with metal ions were investigated by ultraviolet (UV)/visible spectroscopy. The chromogenic behavior of these compounds upon metal ion complexation indicates a specific selectivity toward Ca2+ ion in the presence of other cations tested. The stoichiometry of 3 to Ca2+ ion in the complex is 1:1 and the stability constant of the complex is 1.28×104

Strategies of involvement and moral detachment inHouse of Cards
Authors: Sorlin Sandrine 
Published: April 2018

AbstractThe aim of this paper is to evince the reasons why the viewers tend to ‘root for the bad guy’ inHouse of Cardsin spite of his amoral undertakings. It delves into the linguistic, pragmatic and cognitive strategies employed by the protagonist, Frank Underwood, to ‘transport’ the audience in the narrative while distancing them from moral judgment. It is shown that the ‘Para-Social Relationship’ he constructs with the audience invites them to adapt to his goals and perspective, guiding their emotions and reactions, distracting them from ethical matters through generalised impersonalised aphorisms and transgressive humour. Lastly it proposes a three-level model of producing/viewing processes that are specific toHouse of Cards, highlighting the way the protagonist’s manipulation of audience involvement breaks apart in the last seasons, as the production crew alters the Frank-audience relationship.
Disjointed sum of products by a novel technique of orthogonalizing ORing
Authors: Can Yavuz 
Published: April 2018

AbstractThis work presents a novel combining method called ‘orthogonalizing ORing◯∨$\bigcirc\!\!\!\!\!\!\vee $’ which enables the building of the union of two conjunctions whereby the result consists of disjointed conjunctions. The advantage of this novel technique is that the results are already presented in an orthogonal form which has a significant advantage for further calculations as the Boolean Differential Calculus. By orthogonalizing ORing two calculation steps - building the disjunction and the subsequent orthogonalization of two conjunctions - are performed in one step. Postulates, axioms and rules for this linking technique are also defined which have to be considered getting correct results. Additionally, a novel equation, based on orthogonalizing ORing, is set up for orthogonalization of every Boolean function of disjunctive form. Thus, disjointed Sum of Products can be easily calculated in a mathematical way by this equation.
Generalizations of Steffensen’s inequality via the extension of Montgomery identity
Authors: Aljinović Andrea Aglić , Pečarić Josip , Pribanić Anamarija Perušić 
Published: April 2018

Abstract
In this paper, we obtained new generalizations of Steffensen’s inequality for n-convex functions by using extension of Montgomery identity via Taylor’s formula. Since 1-convex functions are nondecreasing functions, new inequalities generalize Stefensen’s inequality. Related Ostrowski type inequalities are also provided. Bounds for the reminders in new identities are given by using the Chebyshev and Grüss type inequalities.
