Fetal heart rate (FHR) variability appears to be an "early warning system" of fetal hypoxia. FHR variability has been utilized in clinical practice to examine fetal wellbeing. Since 1976 we have used a standardized scoring system to evaluate the cardiotocograph. To eliminate subjective aspects in FHR variability analysis we propose a programmable device utilizing a microprocessor. Preliminary results encourage us to continue this research.

This paper reports the results obtained with various hormonal parameters (HPL, E3, alpha-FP) in evaluating fetal wellbeing during pathologic pregnancies. The expression of hormonal parameters in terms of standard deviation (S.D.) provides a constant endocrine index throughout pregnancy, independently of the adopted parameter. Such methodology reduces error and simplifies interpretation of data. The hormonal index is important not only for reliable diagnosis of a pathologic situation, but also because of its simple interpretation for clinical and practical purposes.

After mentioning the lymphangiographical methods for the study of the lower limb channels, the authors illustrate a new technique which allows, in at least 15% of cases, the simultaneous study of both the superficial and deep lymphatic systems.
Satisfactory results obtained, lasting for years in some cases, following azygos-portal disconnection in selected patients with bleeding oesophageal varices, portal hypertension, splenopathy and gastroduodenal ulcer are referred to. It is suggested that wider use should be made of this technique, particularly in patients in poor condition, because the long-term picture does not include the hyperammoniaemic encephalopathy often associated with extensive portosystemic shunts.
