Preparing for inspection: a tool to maximize quality and minimize risk.

Self-assessment of a dialysis unit can provide an effective means of improving or assuring the level of quality the unit provides in delivering safe and effective care. A tool for use by facility personnel was developed and is being used in 12 dialysis units within one dialysis company. This tool has been useful in identifying areas of risk and in assisting units in developing and maintaining survey readiness. This article presents the facility tool and describes how it may be used to assist other dialysis facilities in risk management and quality assurance activities.

[Acute pulmonary histoplasomis. 1st findings in Czechoslovakia].

A 57-year-old man, who for many years was treated for a pleomorphic lymphoma with cytotoxic drugs and x-ray therapy, died from the generalized tumor process. At autopsy, an extraordinary finding was found in form of acute pulmonary mycosts, which histologically appears to be histoplasmosis. Culture was not attempted, but the diagnosis is based on morphology, both of the organism proper and its intracellular location, and on results obtained by immunofluorescence studies. In numerous pulmonary vessels, endothelial pillows of histiocytes with yeast cells are found, typical for histoplasmosis, but no generalization was found in other organs. The source of the infection is not clear.

[Lymphoepitheloid malignant lymphoma (Lennert)].

A group of 22 lymfoepitheloid malignant lymphomas was singled out from a wider group by means of demonstating nuclear atypias in epitheloid cells. There were three roughly equal subgroups: the first corresponding to malignant lymphogranuloma, the second to different malignant lymphomas of the ono-Hodgkin type. At first, the third group could not be recognized as a malignant lymphoma other than according to different sorts of atypia of each of the epitheloid cells in granulomas.--The general behaviour of malignant lymphomas of the first two subgroups was in keeping with the properties of the respective basic tumour. The third subgroup was more independent. At each subsequent check-up, the epitheloid granulomatous component of the tumour was seen gradually disappearing. It appeared to a secondary feature in most cases. The cause of atypia in epitheloid cells remained unexplained. Nonetheless, these atypias are an important diagnostic facilitating the identification of a more independent form of lymphoepitheloid malignant lymphoma, the subsequent development of which mostly shows signs of a moderately pleiomorphnous malignant lymphoma, sometimes obviously belonging in the T series.
