RESUMO
Sclerosing mesenteritis is part of a spectrum of benign, inflammatory diseases of the abdominal mesentery. It has been called retractile mesenteritis, and other forms include mesenteric panniculitis and mesenteric lipodystrophy. The disease rarely involves the retroperitoneum. We present a case of sclerosing mesenteritis that progressed to ureteral involvement.

Inguinal herniation of the bladder is an uncommon finding with fewer than 200 cases reported in the literature. It is found most commonly in older, obese men with lower urinary tract symptoms. We report a case of inguinal herniation of the bladder in a premature infant.

In the 36 years between June 1965 and February 2001, the US human space flight program has conducted 100 spacewalks, or extravehicular activities (EVAs), as NASA officially calls them. EVA occurs when astronauts wearing spacesuits travel outside their protective spacecraft to perform tasks in the space vacuum environment. US EVA started with pioneering feasibility tests during the Gemini Program. The Apollo Program required sending astronauts to the moon and performing EVA to explore the lunar surface. EVA supported scientific mission objectives of the Skylab program, but may be best remembered for repairing launch damage to the vehicle and thus saving the program. EVA capability on Shuttle was initially planned to be a kit that could be flown at will, and was primarily intended for coping with vehicle return emergencies. The Skylab emergency and the pivotal role of EVA in salvaging that program quickly promoted Shuttle EVA to an essential element for achieving mission objectives, including retrieving satellites and developing techniques to assemble and maintain the International Space Station (ISS). Now, EVA is supporting assembly of ISS. This paper highlights development of US EVA capability within the context of the overarching mission objectives of the US human space flight program.
