A 79-year-old gentleman presented to the Emergency Department (ED) with catheter-related issues on a background of a long-term catheter for previous urinary retention, Hartmann’s procedure for colorectal cancer, and brachytherapy for prostate cancer. A 3-way silicone catheter was placed by ED staff and bladder irrigation commenced. The urine draining following catheterisation was found to be dark and thick, and irrigation fluid was noted to be draining per rectum. CT imaging was performed and demonstrated the catheter tip extending through the posterior wall of the urethra and into the rectum. The patient was admitted under the urology team, and urinary diversion was achieved with a suprapubic catheter. Subsequent imaging demonstrated a periprostatic abscess, which was initially managed with antimicrobial therapy, followed by attempted image-guided drainage. Repeat imaging following a 6-week course of antibiotics failed to show an improvement in the collection. During his inpatient ...

Background Primary soft tissue sarcomas contribute to only 2% of all malignancies arising from the male genitourinary tract. Leiomyosarcoma (LMS) is a malignant soft tissue neoplasm which originates from the mesenchyme and has a characteristic smooth muscle differentiation. Usually, it presents as a painless, firm, slow-growing unilateral scrotal mass. Investigations include imaging, tumor markers, and histopathology. Case presentation A 65-year-old gentleman known diabetic and beta-thalassemic trait was referred to the Urology OPD at Letterkenny University Hospital. His presenting complaint was a left groin lump that appeared 1 year ago and was growing larger in size gradually. According to the patient, his lump was slightly painful (localized) initially that later became painless. He did not report any testicular trauma/infection or UTI. There was no significant history of malignancies running through his family. Clinical examination revealed a soft and lax abdomen, normal testes....

When considering intelligent agents that interact with humans, having an idea of the trust levels of the human, for example in other agents or services, can be of great importance. Most models of human trust that exist assume trust in one trustee is independent of trust in another trustee. The model introduced here addresses so-called relative trust. The idea of relative trust is that trust in a certain trustee not only depends on the experiences with that trustee, but also on trustees that are perceived competitors of that trustee. Such models for relative trust contain parameters to represent the specific dependency between trust for different trustees. In order to tailor the model towards a specific human, dedicated parameter estimation techniques are used. The validation shows that such a model for relative trust is able to predict human trust based behaviour significantly better compared to a benchmark model. Work presented in this paper is a significant extension of the works ...

ABSTRACT Over the past few years, importing design patterns from software engineering to the computer science education (CSE) is followed by defining patterns and pattern languages suitable for pedagogical needs of Computer Science courses. The main goal of patterns incorporation in CSE was to enhance quality of content delivery and comprehension. However it is observed that soon after learning a concept most of the students are not certain about the degree of command over the studied material. Lack of questioning power makes it more devastating. The existing pattern-based materials seem to be insufficient for settling these problems. Hence there is a requirement of pedagogical pattern language that have twofold power of resolving these issues. This paper presents a pedagogical pattern language based on three newly discovered pedagogical patterns to address in time students confidence in their level of comprehension about learned skills.

Wikipedia is the well-nigh successful and most popular free encyclopedia developed by many editors in collaborative manner. It provides multitude of opportunities for online large scale knowledge sharing between virtual communities by letting the viewer to create and edit articles directly in the web browser. Information on Wikipedia is expanding largely, but the increase in quantity is not proportional to quality of the content. The cursory observer of Wikipedia may not be able to differentiate between the good and the bad quality of the content. Despite the success of Wikipedia, trust on Wikipedia content is still questioned because of its open editing model. In this paper primarily the challenges for trust evaluation mechanisms, caused by the significant characteristics of Wikipedia‟s knowledge base are discussed. Existing Wikipedia trust evaluation models are comprehensively surveyed and key issues related to these are highlighted. Finally based on this study new dimensions for ...

Existing search engines like Google, Yahoo etc. provide search results in form of list in a linear fashion. The users can see search results in form of list in this way they can focus only one document at a time and can't see other highly connected web pages that might be more relevant for them. To avoid this situation, a 3D visualization of web search results is proposed in which users can see the structure of interconnected (based on relevance) pages. In this way the chances of viewing the most relevant web pages related to user's search are increased. To achieve this new ranking technique is designed which is capable of ranking web pages in different dimensions instead of a single (linear) dimension like Page Rank.

Creation of a vesicovaginal fistula (VVF) is a complication seen in a variety of patients from prolonged labour and elective hysterectomies to advanced gynaecological malignancies. Causing distressing symptoms such as a loss of continence and vulval excoriation, conventional teaching has always advocated an open surgical approach as described by Sims in 1852. This however may not be feasible in cases of advanced malignancy or attractive to the post-operative patient. In this article the case of a 46-year-old lady with a VVF following elective hysterectomy is discussed. She was successfully managed with endoscopic closure of her fistula with fibrin glue.

ABSTRACT In modern world means of communication and commutation plays a significant role in collective social growth. It is a well observed phenomenon that due to concentration of educational, career, and business opportunities along with easy access to services, population is increasing in urban centers. Increasing population in urban centers is posing many challenges to urban managers and engineers. Ensuring smooth vehicular traffic flow is very important among them. It includes maintenance of current traffic infrastructure, optimal deployment of traffic regulators and cost effective extension of existing infrastructure which requires experimentation of different what-if scenarios. Urban traffic is among those systems which cannot be interrupted in order to experiment hence simulation is most suitable option for policy makers to perform different what-if experiments. Choice of vehicular traffic flow simulator play a vital role in experimenting these what-if scenarios. This paper presents a systematic review of existing vehicular traffic flow simulators proposed and used in research literature. This review includes type of license i.e. the simulator is closed or open source and freeware or proprietary, usage of the simulator i.e. what type of modeling and simulation tasks can be performed using the simulator, developer of the simulator, and citations of the simulator in research literature.
