Vitamin D deficiency is a common occurrence globally, and particularly so in pregnancy. There is conflicting evidence regarding the role of vitamin D during pregnancy in non-skeletal health outcomes for both the mother and the neonate. The aim of this study was to investigate the associations of maternal total 25-hydroxy vitamin D (25OHD) with neonatal anthropometrics and markers of neonatal glycaemia in the Belfast centre of the Hyperglycemia and Adverse Pregnancy Outcome (HAPO) study. Serological samples (n 1585) were obtained from pregnant women in the Royal Jubilee Maternity Hospital, Belfast, Northern Ireland, between 24 and 32 weeks’ gestation as part of the HAPO study. 25OHD concentrations were measured by liquid chromatography tandem-MS. Cord blood and neonatal anthropometric measurements were obtained within 72 h of birth. Statistical analysis was performed. After adjustment for confounders, birth weight standard deviation scores (SDS) and birth length SDS were significantly associated with maternal total 25OHD. A doubling of maternal 25OHD at 28 weeks’ gestation was associated with mean birth weight SDS and mean birth length SDS higher by 0·05 and 0·07, respectively (both, P=0·03). There were no significant associations with maternal 25OHD and other measures of neonatal anthropometrics or markers of neonatal glycaemia. In conclusion, maternal total 25OHD during pregnancy was independently associated with several neonatal anthropometric measurements; however, this association was relatively weak.

1. In a children's home with an average population of about 460 children aged from 0 to 15 years, 473 attacks of acute sore throat, 354 attacks of otitis and 314
attacks of other acute febrile respiratory tract illness were recorded in the 30 months from November 1950 to April 1953.
2. The attack rate for all forms of illness and at all ages was higher among children in a reception group, who were mostly recently arrived in the home, than it was in the permanent residents.
3. Of all ifinesses with the principal signs or symptoms referable to the throat, the proportion that yielded Streptococcus pyogenes rose from about 34 % in the 1–2-year- old children to about 74% in the children aged 10 years or more. Streptococcal sore throats made up about 8% and about 38 % of all febrile respiratory tract illnesses in the same two age groups.
4. The attack rate for streptococcal sore throat varied from month to month between 0 and 6 5 % of the children at risk; only one period of substantially increased prevalence was observed and there was no indication of any seasonal trend. Non-streptococcal sore throat varied between FO and 20 % per month. It was not possible to recognize any epidemics of streptococcal otitis; non-strepto coccal otitis had a definite winter prevalence associated with the rise in the total of non-streptococcal respiratory disease.
5. There was a slight indication that tonsillectomized children had rather milder attacks of sore throat than non-tonsifiectomized under the routine sulphamezathine treatment adopted. About 86 % of all children stifi harboured the causative streptococcus in their throat on discharge from hospital. The tonsifiectomized children lost their throat, but not their nose, streptococci in convalescence more rapidly that the non-tonsillectomized. Among throat carriers, the tonsifiectomized children carried streptococci in their nose more often than the non-tonsilectomjzed at all stages in their illness and convalescence.
6. Bacteriological examination of excised tonsils did not often reveal the presence of streptococci that had been undetected in throat swabs. Twenty-one of twenty- two children who had had a streptococcal respiratory tract ifiness treated with suiphamezathine within the 3 months preceding their tonsifiectomy were found to harbour the same streptococcus in their tonsifiar tissue; only four of eighteen children whose illness had been treated with penicillin still harboured the streptococcus.

In a residential home for children, 367 cases of streptococcal illness were observed in a period of 30 months. The children lived in groups of about twelve in separate cottages. There were 194 occasions on which a streptococcus was thought to have been newly introduced into and produced illness in a cottage; on 132 of these 194 occasions there were no secondary cases of illness. The remaining 62 cottage introductions were followed by one or more secondary cases.
In 27% of the 194 introductions, the primary case of illness seemed to have been infected from a healthy person in the cottage. In all, 30% of introductions of a new streptococcus into a cottage could be attributed to recognized contacts with one or more known infected children.
The most important factor determining spread within the cottage seemed to be the carrier state of the primary case, spread following more often when the primary case had streptococci in the nose either on admission to hospital, or in convalescence.
There was no evidence that spread within cottage bedrooms was of great importance.
In about 35% of the incidents with spread, the initial spread to secondary cases seemed to be from the incubation-stage carriage of the introducer; in 42% it was from his or her convalescent carriage.
The carrier rate in the healthy cottage-contacts was generally higher in cottages experiencing clinical spread of infection than in those that had single-case introductions. There was a strong correlation between the carrier rate in the first week after an introduction and the final bacteriological attack rate, and a weaker correlation with the final clinical attack rate.
Continued spread of infection in a cottage was commonly due to the arrival of new children and was almost always associated with the presence of nasal carriers of streptococci.
The 194 cottage introductions could be grouped into sixty-three overlapping Village epidemics, each apparently derving from a new importation of the particular type into the Village, although the evidence for this was often merely the absence of known infections within the previous few months. Only 13% of the introductions resulted in more than 10 cases, and some 80% had 5 or fewer. Introductions were more frequent in the cottages receiving children new to the homes than in those for the more permanent residents.
The principal factor found as determining the spread from the first cottage to others was the attack rate in the first cottage. Introductions in cottages for school-age children, and especially those in which a child attending the school in the Village grounds was the first to be attacked, also seemed to lead to spread more often than others.
The interval between successive Village introductions of one type did not appear to affect the extent of spread at the second; but the number of cases occurring in the first of two introductions had a notable effect: in no case did two successive introductions both result in a large number of cases of illness.

Children in a residential home whose tonsils had been removed had lower attack rates for streptococcal sore throat than tonsillectomized children. Tonsillectomy did not have a consistent effect on respiratory tract illness.
Tonsillectomy has a similar effect on the outcome of individual exposures to streptococcal infection; the difference was more marked for illness than for simple colonization.
The apparent benefit from tonsillectomy could not be attributed to the ageing of the child, and was considered real. Its magnitude did not seem, however, great enough to justify a policy of extensive tonsillectomy, particularly in view of the possible risks to the child.
A child who had been ill with infection due to one streptococcal type rarely became ill when re-exposed to the same type. In addition there was some evidence in children with tonsils of an immunity, perhaps short lived, which was clearly not type-specific.

1. For each case of streptococcal illness—sore throat, otitis, or other respiratory tract illness—observed in a 30-month study in a large children's home an attempt was made to enumerate the infected contacts from whom the infection might have been derived.
2. Of 459 illnesses, 10·5% seemed to be relapses of a previous illness, and in 10·0% the child was known to have been carrying streptococci for more than 7 days before sickening, so that the causal relation of the streptococcus is in doubt.
3. Of the 365 other illnesses, 31·5% could be attributed with varying degrees of confidence to infection from one specified carrier, 36·8% could have been derived from one or more recognized contacts although there was not sufficient evidence to specify one in particular. For 17·5% no infected contacts were recognized, but infection with the particular streptococcus was known to be present in the community; and for 9·3% there were no contacts and the streptococcus was not known to be present in the Village.
4. Of the ninety-four illnesses for which the source could be specified as one particular carrier, 66% were derived from heavy nasal, 19% from light nasal, and 15% from throat carriers. Persons incubating a streptococcal illness and healthy carriers were each responsible for 31% of the illnesses and convalescent carriers for 38%.
5. It seemed that at least 50% of all illnesses could have been contracted from contacts within the cottage; the proportion due to school infection was much more difficult to estimate but was at least 12%.

Bovine milk antibodies directed against human pathogenic organisms have potential as prophylactic or therapeutic treatments of disorders affecting mucosal surfaces. The cow, however, does not naturally secrete high levels of IgA in milk, the predominant immunoglobulin of the mucosal immune system. We have patented an immunisation protocol that results in increased production of IgA in ruminant milk and in this study established that our protocol can be used on a scale sufficient to produce semi-industrial quantities of milk for processing. Cows were immunised with a common pathogenic yeast, Candida albicans and responded with high levels of antigen-specific IgA antibodies in their milk. The spray-dried milk-protein concentrate (85% protein) powder was shown to reduce adherence of Cand. albicans cells in in vitro adherence assays, demonstrating an ability to retain efficacy through the processing. These results suggest that this milk product may be of therapeutic value if the reduction in Cand. albicans adhesion observed in vitro translates to reduced colonisation in vivo.
