Subdural hygroma: diagnosis with computed tomography. | Nine cases are reported that fulfilled the criteria for diagnosis of subdural hygroma. With the availability of serial computed tomographic (CT) scans, it is possible to document non-invasively the appearance of CSF-density subdural fluid where no prior blood accumulation has been present. | 262,217 | [

Tonsillectomy in Manitoba: who are the patients? the surgeons? the hospitals? | Although tonsillectomy-adenoidectomy rates are declining across North America, this paper suggests they are not falling fast enough. More than half the cases coming to surgery fail to meet accepted standards regardless of who performs the surgery, or where it takes place. Family surgery is still fairly common and is al... | 262,238 | [

Time dependence of triplet-singlet excitation transfer from compact poly rA to bound dye at 77 K. | The nonexponential phosphorescence decay of a highly folded form of poly-riboadenylic acid (poly rA) with noncovalently bound dye is explained by a novel application of a well-known theory of electronic excitation transfer based on the Förster mechanism.

Oxygen consumption in canine skeletal muscle following massive saline infusion. | To study the effect of interstitial edema on tissue oxygen transport, we infused buffered isotonic saline solution at a rate of 200 ml/kg/hr into mongrel dogs for two hours, measuring oxygen delivery and consumption in a skinned, innervated hindlimb. Hematocrit dropped gradually to 10.8 +/- 3.9%. Muscle water content i... | 262,807 | [
