The calibrated-leak balloon catheter, used for the selective catheterization of intracranial arteries, originally incorporated a silicone microballoon at its tip [1]. Latex balloons have now proven superior in elasticity and tensile strength when compared with balloons made of silicone [2] . Consequently, most workers construct the calibrated-leak balloon catheter by gluing a leaking latex micr...

Aims. The aim of the study was to compare endotracheal intubation with i-gel and LMA (laryngeal mask airway) supreme supraglottic airway devices in orbital osteosynthesis surgery. Methods. 134 patients undergoing orbital plasty after fracture were enrolled in our study and were randomized into three groups: 43 in the endotracheal intubation group, 42 in the LMA-Supreme group, and 49 patients w...

Privacy information is prone to be leaked by illegal software providers with various motivations. Privacy leak behavior has thus become an important research issue of cyber security. However, existing approaches can only qualitatively analyze privacy leak behavior of software applications. No quantitative approach, to the best of our knowledge, has been developed in the open literature. To fill...

1 published an original article on the efficacy of the endoscopic management of bile leak after cholecystectomy. Endoscopic management , which involved biliary stent placement with or without biliary sphincterotomy, was successful in 30 of 32 cases (93.8%). Complications of endoscopic management occurred in four of 32 cases (1.3%), but were managed conservatively without se-quelae. 1 Results fr...

Background: Anastomotic leaks in colorectal surgery results in a high morbidity and mortality rate. Serum procalcitonin levels is known as a sensitive and specific marker of sepsis and could be use as a marker for early detection of a leak allowing early intervention. It may help a clinician decide to perform a CT scan even earlier especially when the diagnosis of a leak is uncertain. The aim o...

OBJECTIVE Endotracheal tube air leak pressures are used to predict postextubation upper airway compromise such as stridor, upper airway obstruction, or risk of reintubation. To determine whether the absence of an endotracheal tube air leak (air leak test >/=30 cm H2O) measured during the course of mechanical ventilation predicts extubation failure in infants and children. DESIGN Prospective, ...

OBJECTIVE The study compared laparoscopic sleeve gastrectomy (LSG) staple-line leak rates of 4 prevalent surgical options: no reinforcement, oversewing, nonabsorbable bovine pericardial strips (BPS), and absorbable polymer membrane (APM). BACKGROUND LSG is a multipurpose bariatric/metabolic procedure with effectiveness proven through the intermediate term. Staple-line leak is a severe complic...

In the Oil & Gas pipeline leak detection market today, there are several software based methodologies available – ranging from simplistic pressure wave methods, to real-time model-based volume balance techniques. All approaches have inherent advantages and disadvantages, defi nable in terms of simplicity of implementation/maintenance needs, reliability, cost, robustness, availability, and accur...

Problem: Leakage of the transmission fluid or oil in powertrain systems (i.e., transmissions, cylinder heads, engine blocks, etc.) can cause engine overheating and/or permanent damage. Therefore, it is crucial to run a leak test to inspect for any possible porosity in the casting parts. However, the inspection results for the amount of leakage at given testing times are sensitive to the tested ...
