Meningococcal disease in Belgium. Secondary attack rate among household, day-care nursery and pre-elementary school contacts.

During a recrudescence of meningococcal disease mainly due to serogroup B, 1913 notified cases were investigated in Belgium from 1971 to 1976. From 1971 to 1973, 76 secondary cases were reported out of a total of 1455 cases (5.2 per cent); and from 1974 to 1976, nine secondary cases were reported of a total of 458 cases (2.0 per cent). Seventy per cent of the secondary cases occurred within seven days after the Index case. The 4.7 per cent fatality rate among secondary cases was lower than the 9.8 per cent fatality rate among primary cases. The estimated secondary attack rate was 685 per 100 000 among household contacts, 404 per 100 000 among day-care nursery contacts and 77 per 100 000 among pre-elementary school contacts. These attack rates were significantly higher (P less than 0.001) than the incidence rates in the corresponding age-groups in the general community, indicating the need for prophylaxis in these contacts.

Screening for neonatal hypothyroidism by thyroxine and thyrotrophin radioimmunoassays using dried blood samples on filter paper.

A routine and automatized methodology for thyroxine (T4) and thyrotrophin (TSH) radioimmunoassay (RIA) using dried blood samples on filter paper is described. T4-RIA was performed on one single dot (5 mm diameter equivalent to 4 microliters of serum) while two dots were necessary for TSH-RIA. Reference filter papers were introduced in each assay for quality control. In a preliminary study on 4,155 neonates, samples generally obtained between the 5th--7th day gave a mean 'dot-T4' of 97.95 +/- 36.04 nmol/l and a mean 'dot-TSH' of 10.19 mU/l +/- 8.25, corresponding to 2.47 mU/l of serum. Within an 18-month period (November 1976-April 1978), a total of 16.522 neonates have been screened allowing detection of three cases of congenital hypothyroidism (incidence 1 : 5507), two cases of congenitally low TBG and thirty-three cases of transient hypothyroidism.

Smoking patterns during and before pregnancy: weight, length and head circumference of progeny.

This study indicates that tobacco smoking by the mother is associated with a significant reduction of the newborn's size. This effect cannot be explained by either an association of the smoking habit with malformation, premature birth, exaggerated consumption of coffee matrimonial status or paternal smoking, or by a combination of malformation, prematurity and any one of the other factors. The effect is also unrelated to the continuation or discontinuation of smoking during pregnancy. Paternal smoking seems to be associated with a reduced weight in children born to nonsmoking mothers.

Physiopathological inference by computer.

A system has been programmed to allow model self-structuring to account for observations including both pathological evidence and symptomatological findings. The model modifies its structure in response to supplementary observations. The physiopathological mechanisms formalised by the model can be used for diagnostic purposes. Unknown diseases are diagnosed by direct inference of the relevant physiopathological mechanisms of the model or, if required, by automatic modification of the model that accounts for them.

[Knowledge and opinions on sexuality among young French-speaking Belgians].

We shall limit ourselves to the main topics, leaving the appreciation of the questionnaire to the reader. To evaluate knowledge and opinions on sexuality in young french speaking belgian people, we have questioned : 1210 students at the University of Louvain, 773 in A1 official teaching, 819 in superior free non university teaching and 778 young people being recruted by the belgian army. The following conclusions are global. The mean vocabulary score (rated on 18) in these four samples is 13.22, 14.06, 13.57 and 6.40. This score is in students more than double than the score in young recruted people (and this phenomenon remains even if one includes only boys in higher education). The mean score (13.81) for whole students in higher education type A1 is significantly superior to the one from the University of Louvain. The score observed in official technical teaching A1 is also greater in comparison to free A1. It is also true for free A1 in comparison to the University of Louvain. The words relating to contraception are particularly misknown in the four samples. Regarding the mean score (on 38) on sexual knowledge not related to vocabulary, it is 22.61 at the University of Louvain, 22.53 in free A1 education, 23.72 in official A1 education and 18.535 in young recruted army people. The difference in mean score between official higher education and the University of Louvain is significant ; it is also significant between University of Louvain students and whole students from A1 education (mean : 23.11). There is no significant difference between the score for the University of Louvain and the one for higher free non university education. The mean score in the army, inferior to 50 %, is rather lower than the scores for the other samples, even if limited to boys. Again, questions on contraception are generally misknown. The total score (in %) is 63.98 at the University of Louvain, 64.46 in A1 free education, 67,46 in A1 official education and 44.53 in young army recruted individus. The score is about 20 % lower at the center for recruting and selecting in comparison to the other samples, even if one takes boys only. The difference between the score in A1 official education and A1 free is significant. It is also between total score (65.92) in whole students from A1 technical education and the one at the University of Louvain. It is not significant for the scores in A1 free education versus the University of Louvain. All scores in A1 official education are superior to the one for confessionnal education, even university ; the interpretation of this phenomenon is probably comparable to the influence of the variable "religion". Regarding opinions, we will only indicate that for factors expressing love (tenderness sexuality and mutual esteem) and the possible means of sexual contacts (physical pleasure, a way of expressing love and procreation) : 1...
