BACKGROUND The purpose of this study was to investigate factors associated with carotid blowout in the cervical portion of patients with head and neck cancer in a large cohort. METHODS We reviewed patients with head and neck cancer and identified those with carotid blowout. Variables of patients with and without carotid blowout were compared and associated factors were investigated by logisti...

INTRODUCTION Carotid blowout syndrome is an uncommon complication for patient treated by head and neck tumors, and related to a high mortality rate. OBJECTIVE The aim of this study was to study the risk of carotid blowout in a large cohort of patients treated only by larynx cancer. METHODS Retrospective analysis of patients older than 18 years, treated by larynx cancer who developed a carot...

Enlargement of primary tumor and metastatic lymph nodes in patients with head and neck cancer can be progressive and invade the surrounding vessels despite intensive treatment. Carotid blowout (CBS) tends to occur in these patients, and prompt treatment is required. Surgical management of carotid blowout is technically troublesome because exploration and repair of the previously irradiated or t...

No profile of events can capture all the facts, the chaos, and the many thousands of pages devoted to what the Gulf of Mexico oil blowout was—and was not. During several visits to the Gulf region in 2010 and in the months I spent writing a book on the subject, the best way I found to make sense of the blowout’s many facets was as conceptual topography, its contours shaped by the interlaced fact...

Orbital blowout fracture frequently occurs along the floor or medial aspect of the orbital wall, which are the two thinnest areas of the bony orbit. True trapdoor injury of the orbit is less common and is rare as an isolated medial wall injury, because the medial orbital wall has several bony septa within the ethmoid sinus that provide support and decrease the risk of a trapdoor fracture. Addit...

A detection method of lean blowout in a laboratory-scale premixed gas-turbine model combustor has been proposed from a view point of nonlinear dynamics. The translation error, which quantifies the degree of the parallelism of trajectories in the phase space constructed from the time-series data of the combustion-chamber pressure fluctuations, is used as a detector in this work. The dynamic beha...

We consider examples of loss of stability of chaotic attractors in invariant subspaces (blowouts) that occur on varying two parameters, i.e. codimension two blowout bifurca-tions. Such bifurcations act as organising centres for nearby codimension one behaviour, analogous to the case for codimension two bifurcations of equilibria. We consider examples of blowout bifurcations showing change of cr...

Abstract Sudden tire failure (a blowout) is a major cause of traffic accidents, many of them involving fatalities. If the automobile can quickly identify that a blowout has occurred, the braking system can be programmed to carry out braking and stability control to slow down the vehicle steadily. Hence, timely identification of a blowout or severe leakage is a key enabler of using the braking s...
