[Macrocytosis, polyneuropathy and posterior column disorders caused by malabsorption of protein-bound vitamin B12].

This case report concerns a patient with a vitamin B12 deficiency and a normal Schilling test, who had macrocytosis of many years' duration and finally polyneuropathy. All known causes of a vitamin B12 deficiency were excluded. When the Schilling test was performed with egg consumption, excretion of vitamin B12 was clearly diminished. It appears highly likely that this vitamin B12 deficiency developed as a result of malabsorption of protein-bound vitamin B12.

Normal prolactin response following thyrotrophin releasing hormone in patients with autonomously functioning euthyroid multinodular goitre.

Twelve female patients (mean age 60 years, range 41--74) with euthyroid multinodular goitre and a flat TRH test (median delta TSH 0.9 muIU/ml, range 0--3.5) had normal prolactin responses to TRH (median data prolactin 48 ng/ml, range 6--115). The results are comparable with those in euthyroid patients receiving full substitution doses of thyroid hormone without increasing T3 and/or T4 levels beyond the normal range.
