Mutation screening and association analysis of six candidate genes for autism on chromosome 7q

Genetic studies have provided evidence for an autism susceptibility locus (AUTS1) on chromosome 7q. Screening for mutations in six genes mapping to 7q, CUTL1, SRPK2, SYPL, LAMB1, NRCAM and PTPRZ1 in 48 unrelated individuals with autism led to the identification of several new coding variants in the genes CUTL1, LAMB1 and PTPRZ1. Analysis of genetic variants provided evidence for association with autism for one of the new missense changes identified in LAMB1; this effect was stronger in a subgroup of affected male sibling pair families, implying a possible specific sex-related effect for this variant. Association was also detected for several polymorphisms in the promoter and untranslated region of NRCAM, suggesting that alterations in expression of this gene may be linked to autism susceptibility.

[Accidental falls in nursing homes. A study of the extent and circumstances of accidental falls in nursing homes]

Accidental falls in 54 nursing homes with 2228 elderly residents aged 65 years and over were registered during a period of seven months. During the seven months, 512 of the elderly residents fell on a total of 934 occasions. Forty-two fractures of the neck of the femur occurred. The risk of falls for elderly residents of nursing homes is very high, but the majority of falls do not result in permanent damage. In this investigation, no differences could be demonstrated between staff groups or circumstances concerning falls with and without resultant damage. All falls should be regarded as warnings and result in detailed investigation of the circumstances of the fall in view of prophylactic measures. Accidental falls are caused by a complex interaction between a series of health, therapy, furnishing and attitudes. Various circumstances are emphasized in this investigation which are connected with an increased risk of falling, e.g. vertigo, problems of balance, certain aids and activities in connection with toileting.

[Accidental falls in nursing homes. A study on the role of drugs in accidental falls in nursing homes]

The drug consumptions of 2228 residents in nursing homes aged 65 years and over were investigated and related to accidental falls during a period of seven months. 95% of the residents received treatment with one or more drugs and 33% with six or more drugs. The risk of accidental falls was significantly increased in persons receiving hypnotics, psychomarmaca and anti-Parkinson medicine. Individuals receiving diuretics, particularly thiazides, were less at risk for accidental falls. This investigation revealed an increased risk of falls particularly when residents were receiving treatment with a short-term hypnotic (Triazolam). It is recommended that this finding should be investigated further.

[Social and health inequality in an area of community housing in Odense]

This investigation is a cross-sectional investigation based on the registers available which describe the conditions of health in children born in 1978 and resident in 1987 in two different social districts, one of which was socially, stressed while the other was slightly less stressed. The vaccination coverage was found to be lower in the socially stressed district and lower among immigrant children. More unvaccinated children were observed among children of mothers who received public assistance and of single parents. Hospital admissions on account of diagnoses due to infection were thrice as frequent from the socially stressed district. As regards height, weight and psychomotor status, no differences were observed between the districts. The investigation indicates that social inequalities cause health inequalities and that, in particular, there appears to be a need for health-promoting efforts where the socially stressed environments are concerned e.g. immigrant families.

[Are health and disease equally distributed among children?]

Living conditions for children and young people are of great interest. In previous investigations, differences in sickness among social groups have been found. WHO plans to reduce differences in health conditions among groups within the countries by at least 25%. In this article, attention is drawn to inequalities in health among children in Denmark. Parameters such as the risk of stillbirth, congenital malformations and death during the first year of life do not differ between social groups. Where the less harsh data are concerned, inequalities still exist between social groups, also among Danish children. In relation to the goals set by WHO, it is important to be aware that the existing ways of measurement may not be sufficient.

[Morbidity among children attending nursery schools]

The object of this investigation was to assess the extent to which absence on account of illness in children attending day-nurseries expressed the total morbidity. In four day-nurseries with a total capacity for 164 children, absence on account of illness and symptoms in the children present were registered over a period of 101 weekdays. Children were absent on 5.8% of the days on account of illness. The commonest causes were epidemic children's diseases, colds, sore throats and pyrexia. More than one third of the children present in the day-nurseries presented sign of illness. The most frequent of these were colds. Children were present in the day-nurseries five times as frequently with at least one symptom than they were absent on account of illness. Absence on account of illness provides an incomplete indication of illness among children attending day-nurseries as absence due to illness only represents a lesser quantitative fraction of the total morbidity among these children.

[Allergy presumed by parents of children in nursery schools and day care in relation to conditions of care]

By means of an interview investigation with the staffs of the 11 nursery schools in the Municipality of Odense and 344 day care homes, information was collected about the number of children who received special diets on account of allergy postulated by the parents or predisposition to allergy. 8% of the children in day care and 10% of the children i nursery schools received special diets on account of presumed allergy. Special diets are often instituted without medically documented indications. In institutions with many children on special diets, this frequently results in dietary changes for all of the children. Nursery schools have only very few possibilities for dietary advice. The dietary efforts are not combined with corresponding efforts in other fields such as tobacco smoking, exposure to carpeting and animals. Placing of children with postulated allergy occurs independently of the presence of carpets, animals and smoke in the day care situation. 40-50% of the children in day care homes are passive smokers.
