Blue toe syndrome is the most frequent manifestation of tissue ischemia caused by cholesterol embolization (CE), which can lead to amputation of affected lower extremities, if severe. However, any effective treatment is lacking. We experienced a case of spontaneously presenting blue toe syndrome and concomitant acute renal failure in a patient with multiple atherosclerotic risk factors. CE was ...

objective hyperextension of the big toe is described here as a simple and reliable sign to predict undercorrection of cavus deformity of clubfoot in the ponseti method. materials & methods this retrospective study was conducted on children with clubfoot who were treated successfully by ponseti method in the king fahad hospital, saudi arabia, and emam reza hospital, mashad, iran, from 2003 throu...

•Toe metastasis is a rare pattern of cervical cancer spread.•Enlarged erythematous toe is an important sign suggesting bone metastasis.•Toe metastasis represents a grave prognostic indicator of cervical cancer.

Dam breaks of landslide dams are always accompanied by large numbers of casualties, a large loss of property, and negative influences on the downstream ecology and environment. This study uses the Jiadanwan landslide dam, created by the Wenchuan earthquake, as a case study example. Several laboratory experiments are carried out to analyse the dam-break mechanism of the landslide dam. The differ...

The design of a gravity dam is performed through an interactive process involving a preliminary layout of the structure followed by a stability and stress analysis. This study presents a method to define the optimal top width of gravity dam with genetic algorithm. To solve the optimization task (minimize the cost of the dam), an optimization routine based on genetic algorithms (GAs) was impleme...

Along with the development of virtual reality (VR) technology, simulation system as a new perspective of management methods and technical means in the progress of the project management plays an increasingly important role. This paper presents a Virtools-based visual simulation method and realizes a concrete dam pouring process. It proposes that the mode of the dam for a certain period could be...

Toe-walking is one of the most prevalent gait deviations and has been linked to many diseases. Three major ankle kinematic patterns have been identified in toe-walkers, but the relationships between the causes of toe-walking and these patterns remain unknown. This study aims to identify these relationships. Clearly, such knowledge would increase our understanding of this gait deviation, and cou...
