Viral or bacterial infection, anaphylaxis, metabolic, immunologic and genetic aspects, together with mechanical obstruction and asphyxia (including the somewhat simplistic possibility that nasal obstruction and obligatory nasal respirations in the young sleeping infant are responsible for asphyxia) were reviewed.

The importance of the psychologic impact of these deaths on parents and family received considerable attention, although this did not contribute to etiology or prevention.
It was agreed that epidemiologic, virologic, bacteriologic, and metabolic studies had not opened clear pathways to etiologic possibilities and that the difficulty of proving these was
