Long-term changes in medication during pregnancy.

The Finnish Register of Congenital Malformations, established in 1963, rendered possible the study of changes in medication during pregnancy. The study consisted of 659 control mothers who had delivered a healthy child during the years 1964-1984. The data of this long-term follow-up study were collected by interviews at Maternal Health Care Centers after delivery and were completed by filed antenatal data. The results show a continuous decreasing trend in the usage of analgesics and tranquilizers but not in the usage of antiemetics, antibiotics, and vitamins. We believe that in Finland the publicity aimed at unnecessary medication during pregnancy has affected both the mothers and the health personnel.

A multivariate analysis of the risk indicators of reduction limb defects.

In order to evaluate associations of various selected risk indicators with reduction limb defects, data on 453 cases of reduction limb defects and their time-area matched pair controls from the Finnish Registry of Congenital Malformations was studied. A multivariate analysis of the earlier reported associations was performed. This analysis showed that the following risk indicators were associated with the defects: high birth order, threatened abortion, low placental weight, low birth weight, previous malformations in the family, influenza during early pregnancy, other infectious diseases, and mother's alcohol consumption during pregnancy.

Maternal diseases, alcohol consumption and smoking during pregnancy associated with reduction limb defects.

To evaluate the association of acute and common chronic diseases, alcohol consumption and smoking during pregnancy with reduction limb defects (RLD) 453 cases of RLD from the Finnish Registry of Congenital Malformations were studied. RLD cases without additional malformations were analyzed separately. Statistical associations were observed with maternal influenza. Alcohol consumption, and smoking were likewise associated with the defects. Medication, fever and/or other factors may explain the association of RLD with influenza. The relation to smoking was not explained by alcohol consumption or mother's age, and these variables were independent of each other.

Risk indicators of reduction limb defects.

The birth of a child with a reduction limb defect (RLD) was evaluated in relation to vaginal bleeding, threatened abortion, and other complications of pregnancy, placental weight, birth weight, family history, parental age, and the outcome of previous pregnancies. The material consisted of 453 cases of reduction limb defect and an equal number of non-malformed controls matched for time and place. The children were born in Finland during 1964-77. The cases with reduction limb defect without additional malformations were analysed separately. Statistically significant associations were found between the occurrence of reduction limb defect and the following risk indicators: vaginal bleeding, threatened abortion, duration of gestation under 37 weeks, placental weight 400 g or less, birth weight 2500 g or less, and any type of malformation in the relatives. Vaginal bleeding indicated the risk of reduction limb defect to be increased about fourfold; short gestation indicated about twofold risk of reduction limb defect as an isolated malformation. Both low placental weight and low birth weight were associated to a threefold risk of an isolated reduction limb defect. These factors of an abnormal pregnancy indicated even higher risk of reduction limb defect with additional malformations. Preliminary genetic analysis suggests that hereditary factors play no major part in the aetiology of reduction limb defects.

Incidence and secular trends of congenital limb defects in Finland.

The total incidence rate of three selected congenital limb defects was 12.8 per 10 000 births in Finland from 1964 to 1977; 1235 cases were reported to the Registry of Congenital Malformations. The incidence rate of reduction limb deformities was 5.0 per 10 000 births (481 cases), of polydactyly 5.8 (559) and of syndactyly 3.1 (299), respectively. The total incidence rate and the rates for all the subgroups had a statistically significant increasing trend even after the incidence rates were compared to the reporting rate of all malformations (p less than 0.01). No significant variations in seasonal distributions were found. In 69% of the reduction deformities only one or both upper limbs were affected, 20% of the children had only lower limb defects, and 11% of the cases had defects in both upper and lower limbs. In 28% of the cases additional malformations were reported. For comparison, incidence rates of the selected limb defects from 13 other national surveillance systems are presented.

The development of phonological abilities and their relation to reading acquisition: case studies of six Finnish children.

The relation between phonological abilities and reading acquisition and the interindividual variation in the development of different phonological manipulation skills were assessed for six 7-year-old Finnish nonreaders. Intensive time series data were collected by following the children for 13 months. Assessments were conducted every 4 weeks with five phonological manipulation tests. The results indicated gradual progress at the group level. However, analysis of the individual profiles indicated large interindividual variation in the rate of improvement and in the relation between different manipulation skills and reading acquisition.
