    Description / Table of Contents: Summary Background: Coeliac disease mostly becomes evident in young children. The children present with diarrhea, bloated abdomen, dystrophy and are bad-tempered. Children older than 3 years often present with atypical symptoms which makes diagnosis difficult. Method and patients: In a retrospective study we investigated 27 patients with histologically confirmed coeliac disease. We present the correlation between the symptoms at the time of diagnosis, the patient’s age and the results of the antigliadin – as well as the antiendomysium antibody-measurements. Results: The symptoms were strongly dependent on the patient’s age: 18 of the 20 patients younger than 3 years presented with the typical symptoms for coeliac disease, whereas only 1 of 7 patients older than 3 years showed these symptoms. In both groups we found first degree relatives without any symptoms or with atypical symptoms who as well suffer from coeliac disease. Conclusions: In paediatric patients older than 3 years of age with only mild abdominal symptoms or symptoms like anemia and growth retardation a screening for antigliadin antibodies and antiendomysium antibodies should be done. This screening is also useful in asymptomatic siblings of patients with coeliac disease. The histological examination still remains the gold standard for the confirmation of the diagnsosis.
    Notes: Zusammenfassung Hintergrund: Die Symptome der Zöliakie treten charakteristischerweise im späten Säuglings- oder Kleinkindesalter auf und bestehen aus Durchfällen, aufgetriebenem Abdomen, Dystrophie sowie Mißlaunigkeit. Andererseits wird zunehmend über oligo- oder monosymptomatische Formen bei Patienten jenseits des 5. Lebensjahrs berichtet. Methode und Patienten: Wir führten retrospektiv bei 27 Patienten mit bioptisch gesicherter Zöliakie eine Analyse der Symptome bei der Diagnose sowie der Ergebnisse der Antigliadinantikörper- und der Endomysiumantikörperbestimmung durch. Ergebnisse: Es fand sich eine deutliche Altersabhängigkeit: 18 von 20 Patienten, die jünger als 3 Jahre waren, zeigten eine für die Zöliakie typische Symptomatik. Dagegen war dies nur bei 1 von 7 Patienten jenseits des 3. Lebensjahrs der Fall. In beiden Altersgruppen fanden sich Verwandte 1. Grades mit Zöliakie, die asymptomatisch waren oder nur uncharakteristische Symptome aufwiesen. Schlußfolgerung: Bei älteren Patienten mit unklarer abdominaler Symptomatik oder anderen isolierten Symptomen wie Eisenmangelanämie oder Wachstumsstörung sollte die Indikation für die Bestimmung der Antigliadinantikörper IgA und IgG sowie der Endomysiumantikörper großzügig gestellt werden. Dies gilt auch bei asymptomatischen Kindern aus Familien mit bekannten Zöliakiepatienten. Der Goldstandard für die endgültige Diagnose der Zöliakie bleibt nach wie vor die Histologie.

    Notes: Summary In order to investigate the mechanism of action of photodynamic therapy (PDT) with sulfonated aluminum phthalocyanine (AISPc) in squamous cell carcinoma, animal experiments were performed in induced carcinomas of the mucosa of the hamster's cheek pouch and skin of the laboratory mouse. Histological examinations revealed signs of massive interstitial bleeding, indicating a vascular response to PDT with AISPc. It was also possible to induce similar change adjacent to newly formed vessels at the margin of an inflammatory reaction in the cheek pouch of five hamsters in the absence of tumor cells. Implanted human squamous cell carcinoma cells in athymic nude mice showed that carcinoma cells removed immediately following PDT remained viable, while tumors left in situ became necrotic. These results suggest that the primary effect of PDT with AISPc in vivo is not the malignant cell itself, but the vascular stroma of the tumor or in the immediate vicinity of the latter.
