    Description / Table of Contents: Zusammenfassung. Eine neue endoskopische, intraluminale Valvuloplastik wird beschrieben. Es handelt sich hierbei um einen einfachen, ambulant durchführbaren Antirefluxeingriff, der bei Patienten mit frühen Stadien der gastrooesophagealen Refluxkrankheit eine Alternative zur lebenslangen medikamentösen Dauertherapie bieten könnte. Die Technik des Eingriffs, die Effektivität und erste Langzeitergebnisse im Tierversuch an Pavianen werden dargestellt.
    Notes: Summary. A new endoscopic intraluminal valvuloplasty is described. The procedure provides a simple, easy outpatient approach for antireflux surgery and is applicable to patients with early gastroesophageal reflux disease as an alternative to chronic life-long medical therapy. The feasibility, durability and efficacy of the procedure in baboons are reported.

    Tumour steroid hormone synthesis and estrogen receptor status in breast cancer patients (1981)
    Springer
    Breast cancer research and treatment 1 (1981), S. 263-266

    Notes: Summary The capacity of breast cancer to synthesise active androgens and estrogens has been related to estrogen receptor (ER) status in 79 postmenopausal patients with breast cancer. Although there was no quantitative relationship between levels of ER and steroid metabolism in ER positive tumours, there was (a) a positive correlation between estrogen synthesis and ER positivity and (b) increased androgen synthesis and ER negativity. This may imply an inherent difference in the handling of hormones in ER positive and negative tumours.

    Notes: Summary Certain commonly taken pharmaceutical preparations induce increased levels of plasma prolactin. The effects of these drugs on (a) tumor steroid receptors and metabolism, and (b) plasma hormones and hormone binding proteins have been studied in postmenopausal women with breast cancer. Two groups have been compared, 18 patients on drug treatment for at least 2 months and 15 subjects with no history of drug ingestion. Patients taking medication had significantly higher levels of plasma prolactin compared with control women. No significant difference was observed between the groups with regard to the plasma concentrations of dehydroepiandrosterone (DHA) and its sulphate (DHS), testosterone, estrone, estradiol-17β, sex hormone binding globulin (SHBG), and albumin. Similarly, no difference was observed between these two groups with regard to estrogen receptor (ER), progestogen receptor (PR), or androgen receptor (AR) levels in the tumors nor their ability to metabolize (7−3H) testosterone. It is considered that the ingestion of these drugs does not affect tumor mechanisms involving steroids.
