Chronic sinusitis in a patient with selective IgG4 subclass deficiency controlled with enriched immunoglobulins.

A 71-year-old female patient with no major history of infection had presented with recurrent chronic purulent sinusitis over the past 3 years.

[HemoCue: preliminary considerations about its use in hemodialysis].

HemoCue Hb 201+ is a portable photometric analyser providing easy, rapid and accurate determination of hemoglobin from arterial, venous or capillary blood. It is worth that dialysis units have knowledge of its use for a close hematologic monitoring of their patients and a judicious management of erythropoietin (EPO). For the autodialysis <> centers, it allows a flexibility that private laboratories cannot have in daily practice.
