A retrospective study concerning anamnestic data as well as an internal and dactyloscopic examination were caried out on 75 woman who were delivered from a deformed child. Apart from the well-known causes of a deformity the chronic arterial hypertension is emphasized as teratogenetic factor. The dactyloscopic examination did not result in an accumulation of stigmata which refer to a genetic condition of the deformities. Differences concerning the distribution of patterns on the finger-tips need further investigations; at present they are not yet to be explained.
Investigations on the influence of the diuresis effect upon the results of quantitative oestrogen and HCG determinations revealed that the oestrogen values increase with the 24-hour amount of urine. Oliguria and polyuria affect oestrogen excretion to a considerable extent; they have to be taken into account in prenatal diagnosis of pregnancy. Comparative HCG checks show that HCG concentration also varies considerable depending on fluid excretion. Diagnostic errors can be diminished or avoided when the quantitative HCG assessment is made on the 24-hour urine and then referred to the whole amount of urine.
After having described the bases of dactyloscopy, the authors report on the clinical importance of this method in gynecology and obstetrics. Own results about Turner's syndrome and first experiences of the dactyloscopic examination of mothers of malformed infants are discussed. The patients with XO Turner's syndrome in our series have a ridge count of 181, comparable to the value of 178, 6 observed by Penrose. Mothers of infants with congenital malformations have no different dactyloscopic features in comparison with the controls.
