Non-accidental injury to children: a survey of professional attitudes.

A small sample of general practitioners was questioned about non-accidental injury to children. Differences emerged between those qualifying before and after 1960. Differences were also found in management between the general practitioners and other workers in this field, health visitors, social workers and the police. The need to include this subject in the continuing education of general practitioners is stressed.

Occurrence of pulmonary fat and bone marrow embolism.

The lungs of 136 persons dying as a result of road traffic accidents were studied retrospectively for the presence of fat and bone marrow emboli. Comparable investigations were made in 54 cases of acute myocardial failure reported to the medicolegal authorities and in 50 cases of fatal drug overdose. A further 50 cases of myocardial failure dying in hospital were studied for the presence of bone marrow embolism only. It was considered that despite occurrence of an occasional anomalous case, both fat and bone marrow emboli are related to injury but that the incidence and severity of bone marrow embolism in particular depends greatly upon the conditions of the accidental death. The occurrence of pulmonary embolic phenomena in cases of natural death was attributed to resuscitative measures rather than the underlying condition. The results indicated that the medicolegal significance attached to the findings should, by themselves, be limited to the positive identification of injuries sustained before or at the time of death in the individual case.

Cot deaths in Edinburgh: infant feeding and socioeconomic factors.

One hundred and twenty-six consecutive cases of sudden infant death syndrome (SIDS) in the Edinburgh area have been studied with particular reference to the interrelationship of feeding, associated biochemical changes, and social status. There was an excess of cases born to parents in Social Classes IV and V: the effect was maximal in children who dies beyond 12 weeks of age. A low-grade uraemia was discovered in approximately one-fifth of the cases; analysis showed this to be related most strongly to bottle-feeding. Feeding habits were found to be associated with social class and this accounted for the relationship between bottle-feeding and the youth of mothers and also for an apparent relationship between uraemia in the infant and social class of the mother. Mothers of SIDS children were younger than expected and SIDS was found to be electrolyte imbalance is common in SIDS cases, nor did the findings support the suggestion that cross-infection due to overcrowding is an important aetiological factor. The significant factors of young motherhood, low social status, bottle-feeding, and mild uraemia in the babies are interrelated and seem to focus attention on unwitting 'mothering problems'. It is, however, not easy to see how this, or any other hypothesis, can account for all cases of SIDS.

Pulmonary histological appearances in fatal paraquat poisoning.

The paper describes the histological appearances in the lungs from 11 fatal cases of paraquat poisoning. The study originated as an attempt to define the sequential changes in the condition and, from them, to assess the mode of action of the herbicide in the human. The main features of the "paraquat lung" include haemorrhage, extrusion of macrophages, oedema, "honeycombing", fibrosis and, rarely, epithelial hyperplasia. The indications are that the changes are progressive once a threshold tissue concentration has been reached. The appearances are compared to those in poisoning by hyperbaric oxygen and it is hypothesized that the toxic action of paraquat is to sensitize the lungs to oxygen at atmospheric pressure.

Joint Committee of Aviation Pathology: X. Previous disease in aircrew killed in flying accidents.

This review article discusses the role of previous disease in military, private, and commercial pilots under the headings of occurrence, accident causation, and accident prevention. The importance of minor disease in military flying is stressed as are psychiatric disorders and alcoholism in general aviation. Disease of the coronary arteries is considered with special reference to commercial operations, where the importance of double crewing is emphasized. While symptomatic disease must always be significant, some of the problems associated with increasingly severe selection on the basis of asymptomatic disease are discussed.
