RESUMO
By screening faecal samples collected over four consecutive years (2002-2005) from hospitalized children with diarrhoea in Palermo, Italy, astroviruses (HAstVs) were detected in 3.95% of the patients. The predominant type circulating was HAstV-1 but, in 2002, only HAstV-2 and -4 were identified. Interestingly, the HAstVs-2 detected appeared to be consistently different in 5' end of their open reading frame 2 from the previously described subtypes. These novel type 2 strains were included in a new 2c lineage based on the phylogenetic analysis and the presence of nine peculiar substitutions.

The authors, after a brief discussion of the main effects of the prostaglandins on renal blood flow, report a case of acute renal failure following the ingestion of diclofenac. Although there is little doubt that diclofenac is among the safest NSAIDs the Authors consider that caution is still necessary, especially in the treatment of older and dehydrated patients.

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.
