OBJECTIVERathke’s cleft cysts (RCCs) are benign epithelial lesions of the sellar region typically treated via a transsphenoidal approach with cyst fenestration and drainage. At present, there is limited evidence to guide patient selection for operative treatment. Furthermore, there is minimal literature describing factors contributing to cyst recurrence.METHODSThe authors conducted a retrospective analysis of 109 consecutive cases of pathology-confirmed RCCs treated via a transsphenoidal approach at a single center from 1995 to 2016. The majority of cases (86.2%) involved cyst fenestration, drainage, and partial wall resection. Long-term outcomes were analyzed.RESULTSA total of 109 surgeries in 100 patients were included, with a mean follow-up duration of 67 months (range 3–220 months). The mean patient age was 44.6 years (range 12–82 years), and 73% were women. The mean maximal cyst diameter was 14.7 mm. Eighty-eight cases (80.7%) were primary operations, and 21 (19.3%) were reoperations. Intraoperative CSF leak repair was performed in 53% of cases and was more common in reoperation cases (71% vs 48%, p < 0.001). There were no new neurological deficits or perioperative deaths. Two patients (1.8%) developed postoperative CSF leaks. Transient diabetes insipidus (DI) developed in 24 cases (22%) and permanent DI developed in 6 (5.5%). Seven cases (6.4%) developed delayed postoperative hyponatremia. Of the 66 patients with preoperative headache, 27 (44.3%) of 61 reported postoperative improvement and 31 (50.8%) reported no change. Of 31 patients with preoperative vision loss, 13 (48.1%) reported subjective improvement and 12 (44.4%) reported unchanged vision. Initial postoperative MRI showed a residual cyst in 25% of cases and no evidence of RCC in 75% of cases. Imaging revealed evidence of RCC recurrence or progression in 29 cases (26.6%), with an average latency of 28.8 months. Of these, only 10 (9.2% of the total 109 cases) were symptomatic and underwent reoperation.CONCLUSIONSTranssphenoidal fenestration and drainage of RCCs is a safe and effective intervention for symptomatic lesions, with many patients experiencing improvement of headaches and vision. RCCs show an appreciable (although usually asymptomatic) recurrence rate, thereby mandating serial follow-up. Despite this, full RCC excision is typically not recommended due to risk of hypopituitarism, DI, and CSF leaks.

OBJECTIVEThe transpterygoid extension of the endoscopic endonasal approach provides exposure of the petrous apex, Meckel’s cave, paraclival area, and the infratemporal fossa. Safe and efficient localization of the lacerum segment of the internal carotid artery (ICA) is a crucial part of such exposure. The aim of this study is to introduce a novel landmark for localization of the lacerum ICA.METHODSTen cadaveric heads were prepared for transnasal endoscopic dissection. The floor of the sphenoid sinus was drilled to expose an extension of the pharyngobasilar fascia between the sphenoid floor and the pterygoid process (the pterygoclival ligament). Several features of the pterygoclival ligament were assessed. In addition, 31 dry skulls were studied to assess features of the bony groove harboring the pterygoclival ligament.RESULTSThe pterygoclival ligament was identified bilaterally during drilling of the sphenoid floor in all specimens. The ligament started a few millimeters posterior to the posterior end of the vomer alae and invariably extended posterolaterally and superiorly to blend into the fibrous tissue around the lacerum ICA. The mean length of the ligament was 10.5 ± 1.7 mm. The mean distance between the anterior end of the ligament and midline was 5.2 ± 1.2 mm. The mean distance between the posterior end of the ligament and midline was 12.3 ± 1.4 mm. The bony pterygoclival groove was identified at the confluence of the vomer, pterygoid process of the sphenoid, and basilar part of the occipital bone, running from posterolateral to anteromedial. The mean length of the groove was 7.7 ± 1.8 mm. Its posterolateral end faced the anteromedial aspect of the foramen lacerum medial to the posterior end of the vidian canal. A clinical case illustration is also provided.CONCLUSIONSThe pterygoclival ligament is a consistent landmark for localization of the lacerum ICA. It may be used as an adjunct or alternative to the vidian nerve to localize the ICA during endoscopic endonasal surgery.

Abstract
Using two-dimensional magnetohydrodynamic simulations, we investigated the gas dynamics around a black hole (BH) plunging into a molecular cloud. In these calculations, we assumed a parallel-magnetic-field layer in the cloud. The size of the accelerated region is far larger than the Bondi–Hoyle–Lyttleton radius, being approximately inversely proportional to the Alfvén Mach number for the plunging BH. Our results successfully reproduce the “Y” shape in position–velocity maps of the “Bullet” in the W44 molecular cloud. The size of the Bullet is also reproduced within an order of magnitude using a reasonable parameter set. This consistency supports the shooting model of the Bullet, according to which an isolated BH plunged into a molecular cloud to form a compact broad-velocity-width feature.
DINA Bits - Small Services Growing in the DINA System
Authors: Glöckler Falko , Englund Markus 
Published: May 2018

The DINA system (“DIgital information system for NAtural history data”, https://dina-project.net) consists of several web-based services that fulfill specific tasks. Most of the existing services are covering single core features in the collection management system and can be used either as integrated components in the DINA environment, or as stand-alone services.
In this presentation single services will be highlighted as they represent technically interesting approaches and practical solutions for daily challenges in collection management, data curation and migration workflows. The focus will be on the following topics: (1) a generic reporting and label printing service, (2) practical decisions on taxonomic references in collection data and (3) the generic management and referencing of related research data and metadata:
Reporting as presented in this context is defined as an extraction and subsequent compilation of information from the collection management system rather than just summarizing statistics. With this quite broad understanding of the term the DINA Reports &amp; Labels Service (Museum für Naturkunde Berlin 2018) can assist in several different collection workflows such as generating labels, barcodes, specimen lists, vouchers, paper loan forms etc. As it is based on customizable HTML templates, it can be even used for creating customized web forms for any kind of interaction (e.g. annotations).
Many collection management systems try to cope with taxonomic issues, because in practice taxonomy is used not only for determinations, but also for organizing the collections and categorizing storage units (e.g. “Coleoptera hall”). Addressing taxonomic challenges in a collection management system can slow down development and add complexity for the users. The DINA system uncouples these issues in a simple taxonomic service for the sole assignment of names to specimens, for example determinations. This draws a clear line between collection management and taxonomic research, of which the latter can be supported in a separate service.
While the digitization of collection data and workflows proceeds, linking related data is essential for data management and enrichment. In many institutions research data is disconnected from the collection specimen data because the type and structure cannot be easily included in the collection management databases. With the DINA Generic Data Module (Museum für Naturkunde Berlin 2017) a service exists that allows for attaching any relational data structures to the DINA system. It can also be used as a standalone service that accommodates structured data within a DINA compliant interface for data management.

Published: May 2018

Agriculture and Agri-Food Canada (AAFC) is home to numerous specimen and environmental collections generating highly relational data sets that are analyzed using molecular methods (Sanger and NGS). The need to have a system to properly manage these data sets and to capture accurate, standardized metadata over entire laboratory workflows has been a long-term strategic vision of the Biodiversity group at AAFC. Without robust tracking, many difficulties arise when trying to publish or submit data to external repositories. To even know what work has been carried out on individual collection records over a researchers career becomes a demanding task if the information is retrievable at all. SeqDB was built to resolve these issues by centralizing, standardizing and improving the availability and data quality of source specimen collection data that is being studied using molecular methods. SeqDB also facilitates integration with tools and external repositories in order to take the burden off researchers and technicians having to create adequate systems to track and mobilize their data sets, allowing them to focus on research and collection management.
The development of SeqDB aligns with agile development methodologies and attempts to fulfill rapidly emerging needs from genetics and genomics research, which can evolve and fade quickly at times or be without clear requirements. The success of SeqDB as an application supporting DNA sequencing workflows has put it in the same space as other monolithic architectures before it. As the feature set to support the application continues to increase, the number of software developers vs operations and maintenance staff is difficult to rebalance in our organisation. In an effort to manage the scope for the project and ensure we are able to continue to deliver on our mandate, the sequence tracking workflows of the application will become part of the DINA ecosystem (“DIgital information system for NAtural history data”, https://dina-project.net). Other functions of SeqDB such as collections management and taxonomy tree curation, will be replaced with the DINA modules implementing these functions.
In order to allow SeqDB to become a module of DINA, it has been decided to refactor the application to base it on a Service Oriented Architecture. By doing so, all molecular data of SeqDB will be exposed as JSON API Web Services (JavaScript object notation application programming interface) allowing other modules, user interfaces and the current SeqDB application to communicate in a standardised way. The new architecture will also bring an important technology upgrade for SeqDB where the front end will eventually become a project in itself.
Let me see your iD: Impacts of Environmental Stressors on Aquatic Ecosystems Assessed by (e)DNA Metabarcoding

Published: May 2018

Traditionally, taxonomic characterisation of organisms has relied on their morphology; however, molecular methods are increasingly used to monitor and assess biodiversity and ecosystem health. Approaches such as DNA amplicon diversity assessments are a particularly useful tool when morphology-based taxonomy is difficult or taxa are morphologically ambiguous, for example for freshwater bacteria and fungi as well as many freshwater invertebrate species. DNA metabarcoding provides the ability to distinguish cryptic taxa (which can differ markedly in their ecological requirements and tolerances) and in addition it can provide valuable insights into the genetic and ecological diversity of taxa and ecosystems. While DNA metabarcoding has been used mostly on tissue of sampled specimens, recent years have seen an increased use of metabarcoding on environmental DNA samples: DNA extracted not from sampled specimens, but from the surrounding soil or water. However, the ability of metabarcoding of specimens and metabarcoding of environmental DNA (eDNA) to assess biodiversity and the impact of anthropogenic stressors on freshwater ecosystems is largely understudied. In this talk, several studies that document the advantages and still open challenges of (e)DNA metabarcoding for assessing impacts of environmental stressors on aquatic ecosystems will be presented. These studies, performed in Europe and New Zealand, integrate impacts across different biotic groups, i.e. look at stressor effects on bacterial, protist, fungal and macroinvertebrate communities. Specifically, we use various case studies from freshwater ecosystems to address the following questions:
whether eDNA samples, which can be relatively quickly obtained from the water, can act as reliable proxies for catchment-level stressor impacts by comparing these to DNA obtained from local bulk samples, and
whether DNA metabarcoding data can also provide quantitative information rather than only presence-absence data.
In view of the case studies presented, a perspective on the urgent next steps that need to be taken in order to include genetic tools in routine biomonitoring will be derived and linked to the vision of the international network DNAqua-Net.
Andersen trouve-t-il son conte ?
Authors: François Cyrille 
Published: May 2018

La réédition de « Dødningen » (« Le mort », 1830) sous le titre « Reisekammeraten » (« Le compagnon de voyage », 1835) est considérée par les spécialistes d’Andersen comme un moment déterminant de la poétique de l’auteur, qui aurait entre-temps « trouvé son style ». Plus que le relevé de modifications stylistiques, une étude comparative considérant ces textes comme deux contes plutôt que comme deux états du même conte permet de comprendre dans quel type de projet ils s’inscrivent et, partant, de mieux appréhender les dimensions de la révolution qu’entreprend Andersen en publiant son premier recueil d’Eventyr, fortalte for Børn (Contes, racontés aux enfants) en 1835. Il apparaît notamment que la simplicité et la naïveté du style résultent d’un travail littéraire important et que l’auteur a cherché à supprimer les nombreuses références intertextuelles du texte de 1830 pour proposer des contes à l’apparence populaire et enfantine.
High inventory levels: The raison d’être of township retailers
Authors: Cilliers J. Orpha 
Published: May 2018

Background: This study investigates the cardinal role of optimal inventory decision-making in the performance of small formal retailers in Soweto, constituting a projected, lucrative retail environment. Aim: The research question was how Soweto small retailers make inventory decisions to promote their income growth and age of the business. For this study, a descriptive research design was followed. Setting: The universe of the study comprised all the formal small, medium and microenterprises located in Soweto township. Methods: Using probability sampling, the sample size was set at 650 businesses. Of the 650 completed questionnaires, the responses of 297 respondents operating in the retail grocery and retail general stores sectors were analysed quantitatively using exploratory factor analyses, cluster analysis and cross-tabulation. Results: This study showed that being more inclined to proactively maintain a high level of inventory could result in positive business performance in terms of both growth in income and age. Younger businesses (less than 5 years) could grow if they decide to stock up on sale items, purchase more items for sale, provide for customers’ fluctuating demands and buy more stock to save on transport costs. Purchasing less or the exact amount of stock as what can be sold within a month could be detrimental to the performance of general and grocery retailers in Soweto. Conclusions: The results also show that if retailers want to grow and exist for 5 years and more, they should consider both proactively maintaining a high level of inventory and doing so with ease. In this study, the older (5 years and older) business groups were mostly owned by older people, who showed a tendency to establish themselves in stand-alone shops or smaller shopping centres. Older businesses also tend to buy stock daily or weekly, or when stock is low. These older businesses without income growth were mostly family businesses who displayed contentment with the status quo of business performance and seemed to lack entrepreneurial skills.

Pareto tails in socio-economic phenomena: a kinetic description
Authors: Gualandi Stefano , Toscani Giuseppe 
Published: May 2018

Abstract
Various phenomena related to socio-economic aspects of our daily life exhibit equilibrium densities characterized by a power law decay. Maybe the most known example of this property is concerned with wealth distribution in a western society. In this case the polynomial decay at infinity is referred to as Pareto tails phenomenon (Pareto, Cours d’économie politique, 1964). In this paper, the authors discuss a possible source of this behavior by resorting to the powerful approach of statistical mechanics, which enlightens the analogies with the classical kinetic theory of rarefied gases. Among other examples, the distribution of populations in towns and cities is illustrated and discussed.
O uso de iniciais maiúsculas e minúsculas: estudo comparativo entre o Manual de Redação e Estilo de O Estado de S. Paulo e o Manual de Redação da Folha de S. Paulo
Authors: Vilhena Marina Carneiro de Rezende 
Published: May 2018

O artigo caracteriza-se por um estudo comparativo entre o Manual de Redação e Estilo de O Estado de S. Paulo e o Manual de Redação da Folha de S. Paulo no tocante ao uso de iniciais maiúsculas e minúsculas. Por meio do estudo comparativo, salienta-se a questão da formatação do estilo jornalístico e da consequente padronização de elementos textual-discursivos, reforçando o aspecto da uniformização da escrita jornalística. Há a predominância da convergência nesse estudo comparativo, sobressaindo, assim, a presença efetiva da padronização no texto jornalístico. Por meio do estudo, constatou-se que os manuais expandem a aplicação do uso de iniciais maiúsculas e minúsculas, apresentando um leque maior de situações de emprego das palavras se comparado ao das fontes oficiais (Acordo Ortográfico de 1990 e gramáticas normativas). Dessa forma, os manuais jornalísticos tornam-se referência não só para o jornalista/revisor, mas para os revisores que atuam em outros gêneros textuais e público em geral. Os manuais podem se configurar como fontes de produção do conhecimento sobre a história da língua, já que podem substituir, de forma parcial, as fontes oficiais. O artigo será submetido à apreciação do Caderno Cespuc 31 - revisão, edição e preparação do texto.

Published: May 2018

Introduction: The high mortality rate of prostate cancer in Cameroon, its high incidence, its prevalence, the lack of epidemiological data for the north which for the case is the poorest area of the country led us to conduct this study with for the purpose of presenting the epidemiological, clinical and para-clinical aspects, the cost and means of management with a view to setting up adequate management policies.
Patients and Methods: We conducted a cross-sectional analytical study in the city of Ngaoundéré for a period of 5months. The data were obtained after a survey of patients and collection of results from the pathology registry of the Islamic clinic of Adamawa three months before the start of our study. Results: The prevalence and incidence of prostate cancer were 28.7% and 24.32%, respectively. The average age of prostate cancer patients was 66.5 years. Gleason scores were less than 6 in 44.44% of cases. Risk factors related to familial cancer cases were difficult to determine. The symptoms were dominated in patients by urinary retention associated with polyuria, dysuria and pollakiuria. The means and costs of care were scalable depending on the difficulty of achieving the technique.Conclusion: Prostate cancer remains a real health problem in the north because of its incidence and high prevalence and requires the implementation of a government policy of care.
Portrait de la criminologie québécoise des dix dernières années selon le courant, la méthodologie et l’appartenance institutionnelle des auteurs
Authors: F.-Dufour1 Isabelle , Villeneuve Marie-Pierre , Martel Joane 
Published: May 2018

Nous avons dressé le portrait général des publications parues au cours des dix dernières années de manière à mettre en exergue comment sont représentés les grands courants de la criminologie au sein la revueCriminologie. L’analyse des 188 publications parues depuis 2008 a permis de constater : 1) qu’on dénombre plus de publications s’inscrivant dans les criminologies traditionnelles que critiques ou zémiologiques ; 2) que les méthodologies quantitatives demeurent privilégiées par les auteurs qui se situent dans les courants traditionnels ; et 3) que cette tendance est encore plus forte chez les doctorants et les professeurs de l’École de criminologie de l’Université de Montréal. Nos analyses permettent donc de conclure à un « effet École de criminologie de Montréal » selon le prisme des parutions parues dans la revueCriminologie.
