[Territorial distribution of neural tube defects in Poland]. / Zróznicowanie terytorialne wystepowania wad cewy nerwowej w Polsce.

Neural tube defects (ntd) remain unresolved therapeutic problems, even for contemporary health services. Prophylactic measures are the best methods for limitation of the problem. In many countries, the number of children born with ntd has been reduced significantly, even in 4-5 folds. Authors found that the situation in Poland remains stable since last 20 years. Epidemiological evaluation of the ntd morbidity in Poland is very difficult. There is no National Register of Inherited Defects. Authors observed and analysed mortality and hospitalisation due to ntd in Poland, in early ninetees, and compared these data with information originated from Regional (Wielkopolska) Inherited Defects Register. It was found that ntd mortality and hospitalisation in Wielkopolska was similar to average in Poland. It has been estimated that the rate of children born with ntd in Poland, in 1995 was 2.68 per 1000 live and stillbriths (in 1972-1974 was 2.04). Especially high rates of ntd's have been found in north-eastern part of Country. Incidence of ntd's was higher in rural, than in urban population of the Country.

The dynamics of the changes in the level of the birthweight-specific infant mortality and perinatal mortality rates by age and cause during the eighties is presented. The strongest decline in the birthweight-specific infant and perinatal mortality rates is observed among the newborns weighing less than 2500 g. The level of the low birth weight (7.9% in 1989) and despite the decrease--the infant and perinatal mortality rates among the newborns weighing 1001-2500 g (100.5 and 109.4 respectively in 1989) and among the newborns weighing 601-1000 g (865.3 and 851.1 respectively in 1989) are high comparing to the developed countries.

[Infant mortality and perinatal mortality in Poland in the eighties]. / Umieralnosc niemowlat i umieralnosc okoloporodowa w Polsce w latach osiemdziesiatych.

The dynamics of the changes in the level of infant mortality and perinatal mortality in Poland during 1980-89 by age and cause is presented. The statistical definitions concerning the perinatal period are used according to the World Health Organization's recommendations. There is stronger decline in postneonatal mortality rates then in neonatal rates during the eighties. The level of neonatal mortality rates (14.8 in 1989) and perinatal mortality rates (19.6 in 1989) is high comparing to the developed countries.
