Occult pneumococcal bacteraemia and febrile convulsions.

Over two years 29 children had bacteraemia due to Streptococcus pneumoniae at this hospital. In 15 previously healthy children the site of infection could not be identified, and in most of them, bacteraemia was not suspected clinically. All 15 had high total white cell (greater than or equal to 17 x 10(9)/1) and neutrophil (greater than or equal to 11 x 10(9)/1) counts. Twelve children were under 4 years of age, and of these, 10 had been admitted because of a simple febrile convulsion and one had a prolonged febrile convulsion. Occult pneumococcal bacteraemia has been reported in the USA for more than 10 years, but no series has been reported from the United Kingdom. Occult pneumococcal bacteraemia may be an important cause of febrile convulsions. Persisting bacteraemia and the development of focal infections, including pneumococcal meningitis, have been reported. Meningitis did not occur after occult bacteraemia in our patients. Studies to date have been retrospective, and thus the true incidence of the complications and the best treatment are not clear. A prospective study of children with febrile convulsions could provide answers.

The incidence of Down's syndrome over a 19-year period with special reference to maternal age.

The incidence of Down's syndrome in the Liverpool and Bootle areas from 1961 to 1979 was investigated. A total of 319 liveborn cases was ascertained over this period. Using 3-year moving averages, the incidence of the condition fell gradually from 1.62 per 1000 livebirths for 1961 to 1963 to 1.09 per 1000 livebirths for 1977 to 1979. This trend is significant at the 0.1% level. Over the same period the mean maternal age of Down's syndrome births fell gradually from 36.7 years in 1961 to 29.0 years in 1979. This trend is significant at the 1% level. There was a contemporaneous decrease in the proportion of total births to women over 35 years in the study area. Cytogenetic analysis was performed on 175 out of the 319 index cases (54.9%). Of these, there were 161 trisomies (92%), 11 translocations (6.3%), and three mosaics (1.7%). Between 1969 and 1979 four terminations of pregnancy for Down's syndrome were performed, all for trisomy. Quinquennial age specific incidences for Down's syndrome were calculated for the years 1960 to 1964, 1965 to 1969, 1970 to 1974, and 1975 to 1979. There have been no statistically significant changes over this time. It is suggested that the fall in incidence of Down's syndrome can be explained by the fall in mean maternal age.

Heart rate changes during gauge feeding of neonates.

One hundred and one electrocardiographs (ECGs) were performed on 38 babies, before, during and after gavage feeds. Forty ECGs taken from 22 babies showed a significant bradycardia occurring after tube passage. The risk of this occurring appeared higher with preterms and with babies below 2.5 kg. It is recommended that gavage feeding be restricted to babies above 2.5kg.

Late presentation of vitamin D-dependent rickets.

An 8 1/2-year-old girl presented with rickets. This had developed despite a normal diet and in the absence of symptoms, signs, or laboratory evidence of malabsorption, hepatic or renal disease. The rickets healed with physiological doses of 1-alpha-hydroxy-cholecalciferol. It is suggested that this case provides evidence for genetic and metabolic heterogeneity in vitamin D-dependent rickets.

Trisomy 13 and extended survival.

A 9-year-old boy with classical clinical features of trisomy 13 (Patau's syndrome), with confirmation on chromosome analysis of blood and skin, is reported in view of his relative longevity.
