Comparative Study
[Evaluation of erythrocyte survival by the determination of glycosylated hemoglobin. Clinical value].
In normoglycaemic subjects the haemoglobin glycosylation rate primarily depends on duration of erythrocyte life. Measurements of glycosylated haemoglobin therefore can be used to evaluate erythrocyte life. Indeed, glycosylated haemoglobin is significantly reduced (p less than 0.001) in patients with autoimmune haemolytic anaemia or Minkowski-Chauffard syndrome as compared with patients with non-haemolytic anaemia. In addition, there is a strong correlation (r = 0.92) in non-diabetic subjects between the level of glycosylated haemoglobin and the percentage of daily haemolysis, as determined by a method using 51 Cr-labelled antologous red cells.

Case Reports
[The anterior interosseous nerve syndrome. A rare lesion of a median nerve branch in the forearm. A case].
Apparently spontaneous and isolated lesions of the anterior interosseous nerve--a purely motor branch of the median nerve in the forearm--are extremely rare. Their clinical manifestations are fairly stereotyped, consisting of paralysis restricted to the long flexor muscle of the thumb, the deep flexor muscle of the index finger and the quadrate pronator muscle, without sensory disorders. ⋯ The syndrome may caused by traumas of the forearm or may develop spontaneously, although underlying anatomical abnormalities which may act as predisposing factors are not infrequently found in this case. The natural outcome may be favourable, but surgery may be required to release the nerve.
