Pancreaticopleural fistula is a rare complication of chronic pancreatitis consequent to posterior disruption of the pancreatic duct. The fistulous track ascends into the pleural cavity and gives rise to large volumes of pleural fluid. Pancreaticopleural fistula thus poses a diagnostic problem since the source of pleural fluid is extrathoracic. To further complicate the matter, abdominal pain is...

Companies are faced with serious challenges in environmental and economic crisis. It may become a threat to their financial performance and viability. Thus, there is an urgent need for being resilient in the event of any disruption. The present study aims to assess the performance of companies listed in Tehran Stock Exchange in terms of resilience factors. A standardized questionnaire containing...

Disruption of the epithelial barrier function has been recently associated with a variety of diseases, mainly at intestinal level, but also affecting the respiratory epithelium and other mucosal barriers. Non-pharmacological approaches such as xyloglucan, with demonstrated protective barrier properties, are proposed as new alternatives for the management of a wide range of diseases, for which m...

The occurrence of a capsular rupture during phacoemulsification is not an uncommon entity, with a reported incidence of up to 5-5% when cases are performed by inexperienced residents,l as opposed to 0 9% when performed by an experienced phacosurgeon.2 Other predisposing factors to capsular rupture include: pseudoexfoliation,3 poorly dilating pupils,4 posterior polar cataract,5 and can opener or...

Tracheoesophageal fistulas (TEF) present a perioperative management challenge. A 62 year-old man with esophageal carcinoma presented with a large tracheoesophageal fistula extending most of the trachea. Previously, the patient had two overlapping esophageal and one tracheal stent placed, but he developed progressive tracheal disruption due to esophageal stent perforation near the level of the c...

severe intraabdominal infection associated with abdominal wall, intraperitoneal and remote organ complications, still carries an unacceptably high morality rate. in addition to the fundamental principle of eradication of the source of infection, various treatment modalities have been suggested to improve the commonly grave outcome. amongst these, open management (om) of the septic abdomen, even...

BACKGROUND There are presently several options for the management of posterior urethral disruption. However, these options remain controversial for several reasons. Thus, this medical issue has been continuously investigated. METHODS From 1991 to 2001, 22 patients with complete posterior urethral disruption out of 720 urethral injury cases were retrospectively reviewed using strict criteria. ...

OBJECTIVE Because chylothorax complicating thoracic surgery is difficult to diagnose and failure of nonoperative management necessitates further surgery, we critically evaluated an evolving percutaneous strategy for diagnosing and treating chylothorax. METHODS After thoracic surgery, 37 patients with a clinical diagnosis of chylothorax were referred for lymphangiography for definitive diagnos...

Disruption in public transport networks has adverse implications for both passengers and service managers. To evaluate the effects of disruptions on passengers’ behaviour, various methods, simulation modules, mathematical models are widely used. However, such methods included many assumptions sake simplicity. We here use multiagent microsimulation modules to simulate complex real-life scenarios...
