A mathematical model for the calculation of free and protein bound concentrations of testosterone and estradiol in plasma is presented. The method is based on the knowledge of the total concentrations of all steroids competing for the same binding site on testosterone-estradiol-binding globulin (TeBG), the concentration of albumin, the binding capacity of… (More)
AIMS Langerhans cell histiocytosis is a rare disease with clonal proliferation of dendritic histiocytes, occurring most frequently in infancy and early childhood. In the localized form (single system), the disease is self-limiting, but in the cases of multisystem disease a third of the patients develop organ dysfunction. In these cases the prognosis is… (More)
The registered incidence rate of childhood central nervous system (CNS) tumours has increased in several countries. It is uncertain whether these increases are biologically real or owing to improved diagnostic methods. We explored the medical records of 626 CNS tumours diagnosed in Danish children between 1980 and 1996. Population-based registers were used… (More)
During a 7 year period, 16 episodes of VM-26 (teniposide) hypersensitivity occurred in our Department of Pediatrics. Eight of these (50%) were observed in neuroblastoma patients, of whom a total of 22 children had been treated with VM-26. The predominant signs were facial edema, flushing, urticaria, bronchospasm, tachycardia, and hypotension. All children… (More)
Several classes of ~-languages of labelled Petri nets are defined and related to each other. Since such nets can be interpreted to behave fair, these notions are compared with explicit definitions of fairness for nets.
