[Verification of smoking habits in group studies by anamnesis or determination of serum thiocyanate level?]. / Verifizierung der Rauchgewohnheiten bei Gruppenuntersuchungen durch Anamnese oder Bestimmung des Serumthiozyanatspiegels?

In an unselected series of 336 patients of our clinic for occupational diseases a standardized questionnaire on respiratory symptoms and measurements of lung function (spirometry, body plethysmography, flow-volume-curve) were used to study the relations of these results to smoking habits evaluated by questionnaire or thiocyanate level. Statistical elaboration revealed closer connections between anamnestic data on smoking habits and respiratory impairment than between the latter and thiocyanate level. In conclusion anamnestic data on smoking habits are more reliable than thiocyanate measurements in occupational field studies.

[Effect of ethinyl estradiol sulfonate on the urethral epithelium after bilateral oophorectomy]. / Der Einfluss von Athinylöstradiolsulfonat auf das Epithel der Urethra nach bilateraler Oophorektomie.

The influence of ethinylestradiolsulfonate on the cytological image of the urethra was examined on 11 women who underwent the salpingo-oophorectomia bilateralis. The criterion of the proliferative effect was the Dynamic-Estrogenicity-Index (DEI). After a 6 to 8 weeks treatment at a dosage of one milligram weekly a DEI of 7,27 (+/- 0,74) was attainable. From this point of view we can also summarize a very good urethrotrophic effectiveness. Ethinylestradiolsulfonate is recommended for the treatment of affection on the urethra, especially of those in which an estrogen deficit is the genuine reason or a favoured factor by women after hysterectomia and salpingo-oophorectomia bilateralis for substitution with hormones.
