Hepatic cerebrospinal fluid pseudocyst mimicking hydatid liver disease: a case report

<p>Abstract</p> <p>Introduction</p> <p>An abdominal pseudocyst is a rare complication of a ventriculo-peritoneal shunt. Etiological factors include infection, obstruction and dislodgement. This is the first report of a hepatic cerebrospinal fluid pseudocyst mimicking hydatid liver disease.</p> <p>Case presentation</p> <p>We report the case of an 18-year-old Caucasian male patient who presented with a hepatic pseudocyst secondary to a ventriculo-peritoneal shunt, misdiagnosed as hydatid disease of the liver.</p> <p>Conclusion</p> <p>Hepatic pseudocysts, a rare complication of a ventriculo-peritoneal shunt, have similar clinical and radiological characteristics to those of hydatid liver disease. The formation of a pseudocyst should always be considered in patients with ventriculo-peritoneal shunts <it>in situ</it>.</p

Pancreatic Anastomosis Disruption Seven Years Postpancreaticoduodenectomy

We are reporting a case of a 22 year-old female patient, who underwent a pancreaticoduodenectomy previously for a solid-pseudopapillary neoplasm of the pancreas and was re-admitted seven years later with a pancreatic leak following disruption of the pancreatico-jejunal anastomosis. Exploratory laparotomy revealed a large collection at the level of the pancreatic anastomosis with major disruption of the pancreatico-jejunal anastomosis. The pancreatic stump was refreshed as well as the jejunal site and a duct to mucosa anastomosis was performed. She remains well with a follow up of 18 months

Successful one stage operation for a synchronous, duodenal carcinoma, colonic carcinoma and renal oncocytoma in an adult patient

We report a rare case of synchronous duodenal carcinoma, colonic carcinoma and renal oncocytoma successfully treated using a one-stage surgical approach. Potential risk factors for multiple primary malignancies associated with duodenal carcinoma are discussed. This case illustrates several practice points for consideration: 1. Patients presenting with small intestinal carcinomas have a higher than average chance of developing second primary tumors in other organs; this should be taken into consideration during staging and follow-up. 2. For full staging of patients presenting with small bowel tumors, upper and lower gastrointestinal endoscopy and PET scanning should be considered. 3. A one-stage surgical procedure can be used safely and successfully for multiple synchronous primary tumors

Primary undifferentiated embryonal sarcoma of the liver mistaken for hydatid disease

Primary undifferentiated embryonal sarcoma of the liver is a rare tumor with a peak incidence between the ages of 6 and 10 years. We report a case of a primary hepatic undifferentiated embryonal sarcoma arising in a 21-year-old male mistaken for hydatid disease of the liver. The rapid recurrence of this tumor along the site of attempted percutaneous drainage illustrates some important management points regarding this malignancy

Inflammatory pseudo-tumor of the liver: a rare pathological entity

Inflammatory pseudo-tumor (IPT) of the liver is a rare benign neoplasm and is often mistaken as a malignant entity. Few cases have been reported in the literature and the precise etiology of inflammatory pseudotumor remains unknown. Patients usually present with fever, abdominal pain and jaundice. The proliferation of spindled myofibroblast cells mixed with variable amounts of reactive inflammatory cells is characteristics of IPT. We reviewed the literature regarding possible etiology for IPT with a possible suggested etiology

System design effects on online impulse buying

Purpose – Integrating the two-system (reflective vs. impulsive) model and the “stimulus-organismresponse” framework, the purpose of this paper is to construct and empirically test a model that examines online impulse buying as a phenomenon triggered by system design factors. Design/methodology/approach – A laboratory experimental design with a 2x2 full factorial design involving 151 undergraduate students was used to validate the effects of system design stimuli on online impulse buying. Interactivity and vividness, two design factors, were manipulated and a fictitious VCD movie store was created, with four storefronts representing each combination of treatments. Findings – A compelling and sociable virtual experience as conceptualized with telepresence and social presence has a significant effect on buying impulses over and above traditional marketing/product stimuli. Such virtual experience can be created through the usage of interactive and vivid website features. Furthermore, cognition positively moderates the relationship between buying impulse and the actual purchasing behavior. Practical implications – The findings provide valuable guidance in website design that can stimulate online impulse buying. The results also indicate the importance of providing cognitive intervention at the purchasing stage. Originality/value – A significant extension of the “stimulus-organism-response” framework is to introduce presence as the system stimulus that captures the overall virtual experience and to specify the associated design features; i.e. interactivity and vividness. By incorporating the two-system model, this study offers a theoretical underpinning of the role of cognitive processing in impulse buying

Mitigating the Hospital Area Communication’s Interference using Cognitive Radio Networks

Abstract—The communication infrastructures and devices in hospitals are becoming increasingly wireless because of doctors and nurses are mobile in their work. On the other hand, the hospital patient’s communications or their monitoring generates lot of electromagnetic waves. In this context, deployment of wireless networks should not only meet some performance requirements but should also be aware and able to control the interferences. Cognitive Radio Networks (CRNs) seem to be suitable for delivering high-quality communication services and mitigating radio interferences in hospital environment. In this paper, we discuss the design of hospital networks above CRNs to overcome current constraints. I
