[Cancer formation in a hyperplasiogenic gastric polyp (author's transl)]. / Hyperplasiogener Magenpolyp mit Karzinombildung.

Patients carrying hyperplasiogenic polyps are considered to be a higher risk in regard to carcinogenesis, since a high incidence of cancer has been demonstrated in this group. Usually cancers however originated in other parts of the stomach wall and not in the polyps. Formation of cancer in a polyp is a very rare event. A case report is given of a patient carrying a hyperplasiogenic polyp from which originated cancer. Carcinogenesis is discussed from a formal and causal point of view.

[Separate evaluation of left and right-sided renal function (author's transl)]. / Eine Methode zur seitengetrennten Bestimmung der Nierenfunktion

The PAH extraction of the kidneys was determined separately on each side after catheterisation of both renal veins and the femoral artery during PAH infusion in eleven patients with normal or diminished renal function due to bilateral renal disease and in five patients with only one kidney with normal or diminished renal function. A significant positive correlation was found between PAH extraction and inulin clearance and a significant negative correlation between PAH extraction and the log of the serum creatinine. PAH extraction is a suitable method for quantitative evaluation of right and left renal function.

[Radiological and histological aspects of changes in the knee joint(author's transl)]. / Kniegelenkveränderungen aus radiologischer und histologischer Sicht

A comparison was carried out between histological and arthrographic findings which resulted in a revision in the interpretation of certain radiological signs. Meniscus lesions, osteochondrosis dissecans, chondrosis dissecans and synovitis are considered histologically and radiologically. Dengenerative reactions which can be demonstrated radiologically (irregular margins) consist of mucoid degeneration, trabecular changes, fatty degeneration and oedema of the ground substance. The agreement between arthrographic and histological findings is not unexpected, since both methods demonstrate morphology by different means.
