How does wearing a lumbar orthosis interfere with gait initiation?

The interaction between medical devices and the human body must be evaluated in standardised laboratory tests. Since wearing a lumbar orthosis is assumed to reduce lower back mobility and reinforce trunk movement control through imposed lordosis, this device is expected to affect gait initiation which requires trunk and pelvic rotations. Thirteen healthy subjects were asked to initiate gait without orthosis (control) and orthosis with or without lordosis constraints.

[Biological activity of enoxaprine (PK 10169) in hemodialysis. A dose study].

Anti-Xa and anti-IIa activity were evaluated in 42 patients with chronic renal insufficiency, in an open randomized trial, to determine optimal dose of PK 10169 for prevention of coagulation in extracorporeal circuit during hemodialysis sessions. PK 10169 was given as single doses of 0.75, 1 and 1.

[Calcified and suppurated epidermoid cyst of the spleen (author's transl)].

Reporting a case of epidermoid cyst of the spleen revealed on suppuration brings the authors to review the classification of epidermoid cyst. These are benign tumors in the main present clinically with left hypochondrium pain and the possibility to palpate a splenomegaly or mass in this hypochondrium. The diagnostic approach includes diverse investigations, in particular a series of radiological examinations; surgical intervention will confirm and avoid complications.
