If we pull out rapidly a metallic frame out of a surfactant solution, we arrive at a ”young” soap film with relatively simple features, as noticed first by Lucassen. The weight of the film is equilibrated by a vertical gradient of surface tension. At each level, the local solution concentration c(z) equilibrates with the local monolayers, of surface concentration Γ(z). A detailed analysis of th...

This case report provides background reviewing mortality rates associated with falls from height before detailing the clinical history of a patient who survived a fall from a height of 43 stories. A multidisciplinary team treated both orthopaedic and nonorthopaedic injuries with the ultimate goal of preserving potential for independent function. A discussion of relevant pathoanatomy seen after ...

Blunt traumatic diaphragmatic rupture is an uncommon but severe problem that is usually seen in polytraumatized patients including blunt abdomino-thoracic trauma due to road traffic accidents, fall from height and penetrating injuries.
