[Physical causes of accidental falls among the elderly in their own homes].

Accidental falls in elderly persons involve considerable illness and great hospital costs. During the period 1971-1986, the incidence has risen from 14 to 19 per 1000 annually. Four hundred and seventy-three individuals aged 60 years or more who had fallen in their own homes and who sought help in Odense Hospital after the accident were interviewed consecutively. The replies to these interviews described the circumstances involved in the fall together with the health and social conditions. Women constituted 78% of the material with preponderance of people living alone as compared with the background population. Just under half of the patients had had a previous fall. Fractures were sustained in 40% of the cases. In 51% of the cases, a definite or probable external circumstance was the cause of the fall. In 150 out of 237 accidental falls, caused by external circumstances, the accident was considered to have been preventable by means of eg more accessible lighting, non-slip carpeting, removal of doorsteps, more suitable arrangement of furniture and better supportive measures beside stairs. The risk of falling is found to increase markedly in persons aged 75 years or more. Prophylactic measures are recommended before patients reach this age by means of information to elderly persons and to persons involved in home care about situations involving risks.

Serum zinc and copper concentrations in maternal and umbilical cord blood. Relation to course and outcome of pregnancy.

Abnormal serum zinc and copper concentrations in pregnant women have been associated with a number of maternal and foetal complications during pregnancy and delivery. However, the results of previous studies are contradictory and few large scale studies have been reported. In this study we measured serum zinc and copper concentrations in maternal and umbilical cord blood from 500 Danish mothers at delivery, looking for an association between serum zinc and copper levels and various maternal and foetal complications. Preterm infants (n = 30) had significantly lower serum copper concentrations than reference infants (n = 346) (p = 0.01), whereas there was no difference in serum zinc concentrations. Mothers of preterm infants (n = 34) did not differ in serum zinc or copper concentrations from reference mothers (n = 220). Small for date infants (n = 37) and mothers of small for date infants (n = 47) had higher serum copper levels than reference infants and mothers (p = 0.02 and p = 0.04, respectively), whereas there was no difference in serum zinc concentrations. Serum zinc and copper concentrations in malformed infants (n = 14) and their mothers (n = 17) did not differ from concentrations in reference infants and mothers. Serum zinc and copper concentrations in mothers with various other complications during pregnancy and delivery did not differ from values in mothers with normal pregnancies and deliveries.

Serum selenium concentration in maternal and umbilical cord blood. Relation to course and outcome of pregnancy.

The present knowledge of the role of selenium in human fetal and neonatal development is sparse. In this study we measured serum selenium concentrations in maternal and umbilical cord blood from 500 Danish mothers at delivery, looking for a relationship between various maternal and fetal complications and selenium values. In mothers with uncomplicated pregnancies and deliveries serum selenium concentrations were 0.84 +/- 0.19 mumol/l (mean +/- SD), whereas in cord blood from full-term babies born adequate for gestational age and with no malformations serum selenium concentrations were 0.60 +/- 0.11 mumol/l (mean +/- SD). Mothers who received mineral tablets (other than iron preparations) during pregnancy had significantly higher serum selenium values than unsupplemented mothers (0.92 versus 0.70 mumol/l) (p less than 0.001). Infants of mineral-supplemented mothers also had significantly higher serum selenium values than infants of unsupplemented mothers (0.62 versus 0.58 mumol/l) (p less than 0.001). Preterm infants had significantly lower serum selenium concentrations than full term infants (0.54 versus 0.60 mumol/l) (p = 0.01), whereas infants small for gestational age did not differ in serum selenium concentrations from infants adequate for gestational age. Serum selenium concentrations in malformed infants tended to be lower than in normal infants (0.55 versus 0.60 mumol/l) (p = 0.09), but the difference was not statistically significant, probably due to the small number. Serum selenium concentrations in mothers with various complications during pregnancy and delivery did not differ from values in mothers with uncomplicated pregnancies and deliveries.
