Wet nappies at night could cause infants at risk to die. Tyler first suspected this ten years ago when his head was jerked back from his infant son's cot by the pungent odour of ammonia gas. This theory is consistent with the full epidemiology of cot-death. Ammonia is an insidious poison which has a wide and varied range of effects on the respiratory and nervous systems according to concentration and length of exposure. At its mildest it irritates the tissues. In larger doses ammonia can cause pulmonary oedema and pneumonitis. It can also cause stenosis of affected organs. Its chief danger lies in its potential to disrupt oxygenation at every level throughout the body. Acute and chronic poisoning profiles indicate the possibility that numbers of infants reported as dying from gastro-intestinal or respiratory disease could have been ammonia poisoning victims. Predisposing factors, such as smoking during pregnancy, are shown to contribute to the vulnerability of the infant to ammonia poisoning. The theory provides the framework for the development of an effective programme of infant death prevention.

Twenty-four fatal cases of echo 11 infection in the eleven years 1968-78 are presented. All were children, and could be divided into two groups according to age at death and clinical presentation. The first group comprised 12 babies who died aged between 5 and 11 days after a short illness characterised by collapse, acidosis, and bleeding. At necropsy there was evidence of disseminated intravascular coagulation with haemorrhage into many organs including the renal medulla, suprarenal glands, gastrointestinal tract, and central nervous system. Six cases showed hepatic necrosis which was massive in three. Virus was present in many tissues. Infection was probably acquired from the mothers at delivery in 3 cases. Low maternal neutralising antibody titres and prematurity were thought to be adverse factors in the outcome. The second group consisted of 12 children aged between 9 weeks and 4 years 10 months who died suddenly. Pathological findings included upper respiratory tract infection, pneumonia, encephalitis, and gastroenteritis. Six of this group had been classified as 'cot deaths'. The role of echo 11 in the death of some of these older children is unknown. This report shows the danger of echo 11 to neonates, especially if unprotected by maternal antibody.

Influenza virus infection by the intranasal route was found to be invariably fatal in newborn ferrets. Some obviously died of influenza pneumonia; others died of aspiration pneumonia or showed only minimal or non-specific changes in the lungs. All, however, had severe lesions in the upper respiratory tract, and it is suggested that obstruction of airways and oesophageal passages, in combination with feeding difficulties, played a major role in causing death. The relevance of the findings to the pathology of cot deaths in human infants is briefly discussed.
