We consider a second order,two-point,singularly perturbed boundary value problem,of reaction-convection-diffusion type with two small parameters,and we obtain analytic regularity results for its solution,under the assumption of analytic input ***,we establish classical differentiability bounds that are explicit in the order of differentiation and the singular perturbation ***,for small values of these parameters we show that the solution can be decomposed into a smooth part,boundary layers at the two endpoints,and a negligible *** estimates are obtained for each component of the solution,which again are explicit in the differentiation order and the singular perturbation parameters.

Absolute erythrocytosis,due to an increased production of red blood cells,becomes manifest with hemoglobin(Hb)levels above 165 or 160 g/L or with a hematocrit(HcT)above 51%and 48%in males and females,respectively.1 A minority of patients have polycythemia vera(PV);acquired secondary erythrocytosis frequently occurs due to appropriate or inappropriate erythropoietin(EPO)excess,while congenital secondary erythrocytosis may derive from genetic defects causing tissue *** erythrocytosis occurs in patients with genetic mutations of the oxygen-sensing pathway(VHL,PHD2,_HIF-1-alpha)or the erythropoietin receptor(EPOR)genes.2 Recently,HFE gene variants have been described in sporadic erythrocytoses.3 In a high proportion(about 70%)of patients with erythrocytosis,a specific etiology remains elusive despite extensive testing,and the diagnosis of idiopathic erythrocytosis(IE)is ruled out.
