[Determination of pregnancy duration following terminated hormonal contraception].

The duration of pregnancy as assessed by the rule of Naegele was significant different between patients who became pregnant following termination of oral contraception and patients, who had not taken oral contraceptives. The intervall between stopping the pill and pregnancy was two month. We found a relatively high pregnancy rate in the first three month. The clinical significance is discussed.

[Screening for hypothyroidism in the newborn with a total T 4-RIA method (author's transl)].

A screening method for detection of congenital hypothyroidism is presented in detail in cooperation with the "Austrian Program for Inborn Errors of Metabolism". Screening is performed by measuring the total T4-content of 1/8 inch filter paper dots filled with dried blood of newborns. The strategy for recall of newborns with borderline or pathological T4-values used, results in a definite diagnosis on day 55 of life. The advantages of additional TSH determination in the filter paper dots are discussed. So far (Sept. 1976) 8645 newborns have been investigated, covering the regions of Vienna and Carinthia (Austria). Preliminary studies reveal a slight dependency of the measured T4-values on the day of sampling. Two congenitally hypothyroid children have been diagnosed so far, corresponding fairly well with the reported frequency in the literature (1 : 6000).

Infrared dichroism of the DNA-caffeine complex. A new method for determination of the ligand orientation.

Infrared linear dichroism (LD) measurements on films of the DNA-caffeine complex in terms of the relative humidity (r.h.) show two main effects. Firstly, there is an insertion of caffeine molecules into the DNA double helix (B form), as evidenced by a very strong parallel LD behaviour of the 745 cm-1 band due to the C-H out-of-plane deformation vibration of caffeine. Furthermore, a high r.h. values a modified B form occurs in the complex similar to the B form recently reported by BRAHMS and coworkers for DNA-polypeptide complexes. The reversible B-A transition of the DNA in dependence of the r.h. is not affected in general in the presence of caffeine.

Influence of diftalone on tolbutamide test and i.v. glucose tolerance test.

In 16 healthy volunteers tolbutamide tests or i.v. glucose tolerance tests were performed with and without previous oral administration of 1000 mg diftalone. Blood sugar and serum insulin were assayed in regular intervals. Both with and without previous administration of diftalone blood glucose after tolbutamide did not show any difference. IRI response to tolbutamide, measured by planimetrical integration showed a statistically significant augmentation (0.05 greater than p greater than 0.01) after diftalone. Glucose assimilation (K-value) after diftalone was decreased (0.05 greater than p greater than 0.01) yet within normal range. For the accompanying insulin levels however no statistically significant difference was observed. In addition a normalisation of pathological tolbutamide test after diftalone could be noted in five patients with subclinical diabetes. Our results indicate that diftalone seems to have the following three actions: 1. Enhancement of the tolbutamide action. 2. direct augmentation of IRI secretion, 3. a peripheral action on glucose metabolism.

[Electroencephalographic findings in electronically monitored risk births].

Electroencephalograms showed - in accordance with many authors - important statements of perinatal damage and of her prognosis. The fetal monitoring (electronical and gasanalytical) is able to acknowledge in due time a hypoxic situation and procures favourable to the perinatal morbidity. Gross-pathological electroencephalograms we found in 5% of monitored high-risk babies in contrast to 17% of no monitored intrauterine patients.
