Iron supplemented formula milk related to reduction in psychomotor decline in infants from inner city areas: randomised study.

OBJECTIVE: To compare the effect of unmodified cows' milk and iron supplemented formula milk on psychomotor development in infants from inner city areas when used as the main milk source. DESIGN: Double blind, randomised intervention trial. SETTING: Birmingham health centre. SUBJECTS: 100 infants, mean age 7.8 months (range 5.7 to 8.6 months), whose mothers had already elected to use unmodified cows' milk as their infant's milk source. INTERVENTION: Changing to an iron supplemented formula milk from enrolment to 18 months of age, or continuing with unmodified cows' milk. MAIN OUTCOME MEASURES: Developmental assessments using Griffiths scales at enrolment and at 18 and 24 months. RESULTS: 85 participants completed the trial. There were no significant differences in haemoglobin concentration between the two groups at enrolment, but by 18 months of age 33% of the unmodified cows' milk group, but only 2% of the iron supplemented group, were anaemic (P<0.001). The experimental groups had Griffiths general quotient scores that were not significantly different at enrolment, but the scores in both groups declined during the study. By 24 months the decrease in the mean scores in the unmodified cows' milk group was 14.7 whereas the decrease in the mean scores in the iron supplemented group was 9.3 (P<0.02, 95% confidence interval 0.4 to 10.4). Mean subquotient scores were considerably lower in the unmodified cows' milk group at 24 months; significantly so for personal and social scores (P<0.02, 1.2 to 16.8 [corrected]). CONCLUSION: Replacing unmodified cows' milk with an iron supplemented formula milk up to 18 months of age in infants from inner city areas prevents iron deficiency anaemia and reduces the decline in psychomotor development seen in such infants from the second half of the first year.

Dietary education and iron deficiency anaemia in the inner city.

OBJECTIVES: To assess if a dietary health education programme could be used within existing health resources to reduce the incidence of iron deficiency anaemia in an inner city population. DESIGN: Prospective cohort study. SETTING: Inner city areas of west and south Birmingham. SUBJECTS: A total of 1000 children recorded on the child health computer register. INTERVENTION: Children were recruited at birth and randomised into control and intervention groups. Families in the intervention group received specific health education information at key ages by face to face contact using a range of materials. The control group received standard health education as delivered by the health visitors at the time. MAIN OUTCOME MEASURES: Haemoglobin estimation and iron content of the diet at 18 months of age. RESULTS: A total of 455 children completed the study. Sixty nine (27%) of the control group and 55 (28%) of the intervention group were anaemic as defined by haemoglobin less than 110 g/l. There was no difference in the iron content of the diets offered to the two groups of children. CONCLUSION: In this deprived population we have shown no reduction in anaemia using a targeted nutritional programme and have highlighted the difficulties in conducting health education programmes within the scope of current health resources.

Prevention of anaemia in inner city toddlers by an iron supplemented cows' milk formula.

There are few data to support the use of follow-on formulas in infants from the age of 6 months. In a prospective trial in a deprived inner city area of Birmingham 100 infants who were already receiving pasteurised cows' milk by 6 months of age were enrolled and randomised either to receive a follow-on formula or to continue on cows' milk from 6 months until 18 months. At 18 months of age the follow-on formula group returned to cows' milk and both groups were followed up until 24 months. Iron status, growth, and nutritional status were analysed at intervals of six months. At enrollment, no differences in haematological status were evident. However, by 12 months of age, 31% of the cows' milk group were anaemic (haemoglobin concentration < 110 g/l) compared with only 3% of those receiving follow-on formulas. At 18 months, 33% of the cows' milk group were anaemic compared with only 2% of the follow-on formula group and by 24 months of age none of the follow-on formula group was anaemic, whereas 26% in the cows' milk group still had a haemoglobin of < 110 g/l. Mean corpuscular volume was significantly smaller and ferritin significantly lower in the cows' milk group at 12, 18, and 24 months. Dietary iron intake was higher in the follow-on formula group at 12 and 18 months but not at 24 months, when both groups were back on cows' milk. Infants and toddlers at high risk of iron deficiency are therefore unlikely to become anaemic if receiving a follow-on formula, although the relative merits of follow-on formula compared with an ordinary infant formula remain uncertain.

An unusual case of mosaic Down's syndrome involving two different Robertsonian translocations.

A baby girl with some of the stigmata of Down's syndrome was found to be a mosaic with three different cell lines: 45,XX,-13,-21,+t(13q21q)/(46,XX/46,XX, -21,+t(21q21q). The chromosome rearrangements detected in this patient appear to have arisen de novo. In the normal cell line the terminal end of the p arm of one chromosome 21 is thought to have been damaged. It seems probable that this is related to the other chromosomal anomalies found.

Molybdenum co-factor deficiency: an easily missed inborn error of metabolism.

A female patient is described with combined deficiency of sulphite, zanthine and aldehyde oxidase. She presented at the age of four weeks with intractable seizures. Initially the diagnosis was suspected because of a very low serum urate level (23 mumol/1-1). This condition can be easily missed and it is proposed that measurement of serum urate be included in the metabolic assessment of neonates with unexplained seizures and developmental delay.

Cerebral systemic lupus erythematosus.

Cerebral systemic lupus erythematosus is uncommon in childhood. Three further cases are presented to draw attention to the unusual and varied clinical manifestations of this condition.
