Spina bifida and potatoes.

The results of a retrospective survey of the dietetic and other habits of the mothers of 83 children with spina bifida (mostly schoolchildren with meningomyelocele) were compared with 85 carefully matched controls. The survey was particularly concerned with the consumption of or contact with potatoes by the mothers. No significant differences were found in the amount of potatoes eaten as reported by the mothers (mean for spina bifida group 3.60 1b (1630 g), and for controls 3.98 1b (1800 g) per week). Of the seven other comparisons associated with potatoes only one (obtaining them from the chip shop or restaurant) was significant, the mothers of the children with spina bifida being more likely to obtain some of them from this source.When examining other aspects of diet it was found that the mothers of spina bifida children reported a lower consumption of a number of important foods, though the deficiency was not significant in any instance. These mothers were also significantly more likely to have been prescribed drugs other than iron and vitamins early in pregnancy and to have reported a wider variety of illnesses.The results in general do not support the hypothesis that the quantity of potatoes taken is important. They do lend support to the view that poor dietary habits are associated with a higher incidence of spina bifida irrespective of social class. Furthermore, general ill health in the mother may be implicated.

Prevention of Rh-haemolytic disease: results of the Liverpool "low-risk" clinical trial.

A clinical trial is reported in which Rh-negative primiparae, just delivered of an Rh-positive ABO-compatible infant and in whom fetal cell counts after delivery suggested less than 0.2 ml of circulating fetal blood, were treated with about 200 mug of anti-D gammaglobulin. Three (0.36%) out of 844 women thus treated developed anti-D in the subsequent six months; this is 10% of the incidence in untreated controls. Three (1.8%) out of 171 treated mothers had anti-D at the end of the second Rh-positive pregnancy, and this is 18% of the incidence in controls.Possible reasons for the occasional failure of the treatment are discussed and the results of this trial are compared with those of a previous trial in which 1,000 mug or more of anti-D was given to a different group of mothers. The combined results of the two trials lead to the conclusion that the passive administration of anti-D gammaglobulin after delivery affords in this population of Rh-negative women a 95% protection rate in the postdelivery period and an 89% protection rate by the end of the subsequent pregnancy.
