The yield of a diagnostic hospital dyspnoea clinic for the primary health care section.

Objective: To investigate the impact of a combined examination programme with treatment advice on patients from general practice with dyspnoea.

Design: Prospective study with 6 months followup.

Setting: Regional hospital offering care for patients from 74 general practitioners.

An enzyme-linked immunosorbent assay for plasma-lactoferrin. Concentrations in 362 healthy, adult blood donors.

Very different concentrations of plasma-lactoferrin in healthy adults have been reported in the literature. We compared three commercially available lactoferrins and lactoferrin purified in our laboratory as calibrators in an ELISA. No statistical differences among these preparations of lactoferrin were detected.

Identification of patients with hereditary haemochromatosis by magnetic resonance imaging and spectroscopic relaxation time measurements.

A total of 4302 healthy blood donors were screened for elevated serum ferritin and transferrin saturation. Fifteen had increased serum ferritin at a follow-up examination. Five relatives of these donors also entered the study.

Variations in serum erythropoietin and transferrin receptor during phlebotomy therapy of hereditary hemochromatosis: a case report.

Serum levels of transferrin receptor and erythropoietin were determined in 2 patients with hereditary hemochromatosis undergoing phlebotomy therapy. The objective of the study was to determine changes in serum transferrin receptor and serum erythropoietin occurring during therapy, and to investigate if such changes could be useful to monitor the therapy. The study showed that serum transferrin receptor, and to a lesser extent serum erythropoietin, may be better parameters than serum ferritin as indicators of when phlebotomy should be discontinued.
