[Atrial dissociation in complete intra-atrial block]. / Dissociazione atriale da blocco intra-atriale completo.

Atrial dissociation due to a complete intraatrial block is a very rare electrocardiographic occurrence. Two cases of this atrial arrhythmia characterized by two atrial ectopic beats of different origin are reported. The electrophysiologic mechanisms of the arrhythmia are discussed briefly.

[The importance of glycosylated hemoglobin in the prevention of diabetic vasculopathy]. / L'importanza dell'emoglobina glicosilata nella prevenzione della vasculopatia diabetica.

Glycosylated haemoglobin (HbA1c), less portion of total haemoglobin, represents a biochemical marker in glucidic metabolism of diabetic patient. Authors refer in their experience relaps of cerebrovascular accidents have been of 37% in diabetic patients, while they have been only of 11% in non diabetic patients. They conclude that glycosilated haemoglobin periodic value might favourably condition diabetic vasculopathy prognosis.
