[Characteristics of 86 infants' cluster with A.L.T.E. (Apparent Life-Threatening Event): similarities and differences versus main risk factors for SIDS].

In this study we have gathered 86 ALTE infants' characteristics about physiological, familiar, remote and near pathological case history, modality of apnoea episode's presentation, environmental and behavioural conditions of babies and we have compared these ones with main risk factors for SIDS to find possible similarities or differences. Many of the already known differences or similarities between ALTE and SIDS have been confirmed by our data and new ones have been observed. So we can say that the association between ALTE and SIDS remains contrasting because beside undiscussed factors of association there are other ones which differentiate the two Syndromes.
