    Notes: Summary Normal tissue as well as various benign and malignant lesions of the breast were histochemically examined for the presence of the Thomsen-Friedenreich (TF)-antigen. Fluorescein- or 3H-labelled peanut agglutinin was used for this purpose, a lectin that is known to have a high affinity for the TF-antigen. The occurrence of this TF-antigen seemed in all cases, even in the carcinoma lobulare in situ that is regarded as being derived from myoepithelial cells by some authors, to be associated with a secretory condition. Its presence (free and neuraminicacid covered) in normal, hyperplastic and malignant breast tissue, however, cannot be considered a specific tumour associated antigen as has been previously assumed. Furthermore the investigations have shown that the intensity of fluorescence for peanut agglutinin (PNA)-receptors was generally stronger in differentiated carcinomas than in undifferentiated carcinomas of the breast. The histochemical findings are discussed with regard to diagnostical and immunotherapeutical aspects.

    Notes: Summary Serum levels of antibodies against the Thomsen-Friedenreich (TF) antigen were determined for a group of patients with malignancies of the breast, as well as a control group of healthy persons and patients with no breast disease. Despite recent claims of anti-TF levels being severely depressed in patients with breast cancer, we were unable to show any significant differences between the two groups. Standardised anti-TF containing sera or solutions of the TF specific agglutinin from peanuts (PNA) were absorbed with membrane preparations from normal and cancerous breast tissue, but again no differences in absorption were noted. Histological examination, by contrast, showed both free and sialic acid-covered receptors to be present on both normal and malignant breast epithelium. Based on these findings it was concluded that determination of serum anti-TF is an unsatisfactory method of diagnosing breast cancer and that the TF antigen cannot be considered to be carcinoma associated.

    Description / Table of Contents: Zusammenfassung Eine hochgradige Duodenalstenose im Erwachsenenalter kann in seltenen Fällen angeboren sein und findet ihre Ursache in einer intraduodenal gelegenen Membran. Die Anamnese zeigt Wachstumsstörungen mit Erbrechen und Meteorismus und abdominelle Beschwerden. Eine Perforationsöffnung in dieser Membran ist die Ursache fur ein Überleben bis ins Erwachsenenalter. Die Röntgendarstellung und die tiefe Duodenoskopie lassen auf einfache Weise die Diagnose stellen. Differentialdiagnostisch müssen der Volvulus bei Malrotation, Ladd-Bänder und das Pancreas anulare, sowie die Kompression des Duodenums durch Mesenterialgefäße erwogen werden. Das operative Verfahren der Wahl ist die Resektion der intraduodenalen Membran. Dabei ist v. a. die Papilla Vateri darzustellen, da diese nicht selten im Bereich des Septums mündet. Das längs eröffnete Duodenum wird quer verschlossen. Bei der Wind-Sock-Web-Anomalie sollte das Duodenum an der Ansatzstelle des Diaphragmas eröffnet werden. Die Anlage einer Gastrojejunostomie ist inadäquat und zu vermeiden.
    Notes: Abstract A high-grade duodenal stenosis in adults can, in rare cases, be congenital, and its cause is found in an intraduodenally sited membrane. The anamnesis reveals growth disorders with vomiting and meteorism and abdominal complaints. A perforation opening in this membrane is the reason for survival into adulthood. The X-ray appearance and deep duodenoscopy make the diagnosis easy. Volvulus in cases of malrotation, Ladd's ligaments, anular pancreas, and compression of the duodenum by mesenteric vessels must be considered in the differential diagnosis. When the intraduodenal membrane is resected it is most important to expose the papilla Vateri, since this not uncommonly ends in the area of the septum. If necessary, a duodenoduodenostomy is performed. If the windsock web abnormality is present the duodenum should be opened at the point of attachment of the diaphragm. The construction of a gastrojejunostomy should be avoided.
