[Poisoning by hypochlorite-containing disinfectants. A retrospective analysis of 594 cases of poisoning]. / Vergiftungen durch hypochlorithaltige Sanitärreiniger. Eine retrospektive Analyse von 594 Vergiftungsfällen.

Hypochlorite-containing disinfectants or bleaching fluids, if inhaled, may lead to life-threatening poisoning (56% of moderately severe cases, 5% of severe cases) through the immediate liberation of chlorine gas, if they are used together with another cleansing fluid which is very acid. A rough estimate suggests that there must be about 700 cases of such poisonings per year in the Federal Republic of Germany. The characteristic symptom is a respiratory distress syndrome when the liberated chlorine gas is inhaled. Toxic pulmonary oedema and cardiovascular failure can occur if the poisoning takes a fulminating course.

[Renin-secreting renal tumor. Apropos of a case with an ultrastructural and immunohistochemical study]. / Tumeur rénale à sécrétion de rénine. A propos d'un cas avec étude ultrastructurale et immunohistochimique.

A case of renin-secreting tumor of the left kidney in a 36 year-old man with hypertension of five years duration is reported. The antihypertensive therapy was unsuccessful. Following nephrectomy, blood pressure returned to normal values and is still normal, seven years later. There is no evidence of metastasis. The tumor was studied by electron microscopy and by immunohistochemistry. It is composed of two cellular structures normally encountered in the kidney: renin-secreting cells and cells similar to those of the cortical collecting ducts. This benign lesion might be hamartomatous.

[The pathogenesis of spontaneous perirenal haematomas (author's transl)]. / Zur formalen Pathogenese des spontanen perirenalen Hämatoms.

This report deals with two cases of a spontaneous perirenal hematoma. In the first case the spontaneous perirenal hematoma resulted from hemorrhages from the vessels of the stratum fibrovasculare of the renal capsule. This bleedings led to the development of a granulation tissue which in turn is rich in small blood vessels. Due to the lytic activities of this granulation tissue the hematomas became resorbed and finally are transformed into a big pseudocyst which surrounds the lower half of the kidney. On the other hand the new-built vessels of the granulation tissue are the source of further bleedings thereby perpetuating the process. In the second case the perirenal hematoma resulted from two aneurysms of the renal artery. In both cases clinical and radiological investigations had been unable to demonstrate the lesion.
