In the previous issue of Critical Care, Ma and colleagues perform a meta-analysis of five randomized, clinical trials of endothelin antagonists in patients with aneurysmal subarachnoid hemorrhage. There are four trials using clazosentan and one trial with TAK-044. These studies show that endothelin plays an important role in the genesis of angiographic vasospasm. The benefit of these drugs is l...

Let S denote a set of k-dimensional boxes each having integral sides. Let I'(S) denote the set or all boxes which can be filled completely with translates of elements of S . It is shown here that S contains a finite subset B such that l?(B) = I'(S) . This result was proved for k = 1,2 in an earlier paper, but the proof for k > 2 contained an error. This research was supported in part by the Nat...
