5 patients who presented with CSF leaks between the years 2002-2009 were evaluated according to the etiology of the leak. An active CSF leak was confirmed in all patients and the site identified. A repair was planned using either vascularized septal mucosal flaps or free grafts of nasal mucosa. Preparation of the graft recipient site is important. A tissue glue either Tisseal or in the later ca...

We present a novel leak detection algorithm. To prove the absence of a memory leak, the algorithm assumes its presence and runs a backward heap analysis to disprove this assumption. We have implemented this approach in a memory leak analysis tool and used it to analyze several routines that manipulate linked lists and trees. Because of the reverse nature of the algorithm, the analysis can local...

The popularity of Android applications have grown dramatically in the last few years. Android applications run on mobile devices that have limited memory resources. Although Android has its own memory manager with garbage collection support, many applications currently suffer from memory leak vulnerabilities. These applications may crash due to out of memory error while running, and this will l...

A persistent pulmonary air leak, whether as a result of pulmonary surgery or as a result of a traumatic or spontaneous pneumothorax, is a difficult and frustrating problem to manage. Several therapies have been employed, including thoracotomy and repair of the air leak, prolonged tube thoracostomy suction, and chemical pleurodesis. We report two cases in which patients with a prolonged air leak...

A chyle leak can occur as a complication after neck or chest surgery. Such a leak prolongs the hospital stay and is sometimes life-threatening. The treatment options are conservative management, interventional radiologic embolization, and surgery. Thoracoscopic ligation of the thoracic duct has emerged as a promising and definitive treatment. The case of a 65-year-old Japanese male patient with...

A model-based approach to detect and isolate non-concurrent multiple leaks in a pipeline is proposed, only using pressure and flow sensors placed at the pipeline ends. The approach relies on a nonlinear modeling derived from Water–Hammer equations, and related Extended Kalman Filters used to estimate leak coefficients. This extends former results developed for the single leak case, but with the...

background: aluminum phosphide is the common cause of poisoning in adults in india, with a very high case fatality ratio. we studied five patients of aluminum phosphide poisoning with polyserositis. methods: we enrolled all patients with aluminum phosphide poisoning presenting to emergency medical department, at a tertiary care hospital in northwestern india from january to july 2006. these pat...

BACKGROUND Noninvasive ventilation (NIV) is usually applied using bi-level positive airway pressure devices, and many of these devices use a single-limb patient circuit with an integrated leak port to purge the circuit of exhaled carbon dioxide. Sometimes bronchodilator therapy is indicated in pediatric patients, but there have been no studies of the optimal nebulizer position, with respect to ...

OBJECTIVE The objective of this study was to compare the air leak duration of two regulated chest tube modes following pulmonary lobectomy. METHODS This is a prospective randomized trial on 100 consecutive pulmonary lobectomies (2010-11) performed for lung cancer. A single 24-French chest tube was connected to an electronic system capable of maintaining the pleural pressure within preset valu...

OBJECTIVES During noninvasive positive pressure ventilation (NPPV), the gas leak that commonly occurs around the mask can render NPPV ineffective. We evaluated the effects of gas leak on inspiratory trigger function during NPPV with bilevel pressure and ICU ventilators. In addition, we evaluated the effects of gas leak on fraction of inspired oxygen (Fio(2)) and humidification. METHODS Air le...
