[Contrast roentgenography of the elbow joint in children].

The investigation of roentgenograms made after a preliminary contrast study of the elbow joint has shown that traumas may be followed by pathological changes of the cartilaginous tissue, elbow bursa and filling of the fossae of the olecranon and coronary processes by scarry and osseous tissue. The pathological changes mentioned above result in disturbances of the movement of the elbow joint.

[On the problem of radiation damage caused by roentgenography of the thorax (author's transl)].

The risk factors for radiation induced cancer (no dose threshold) given by UNSCEAR and ICRP are discussed. Under the (uncertain) supposition of the validity of these values for the roentgendiagnostic the number of cases induced by the mass screenings (VRRU) are estimated (lung and breast cancer, leukaemia). For 30 radiophotofluorographs of the thorax per person during the whole life there may be induced about 180 cancer of the lung, 5 of the breast and 27 leukaemias each year. These numbers are compared with the cases per year of lung tuberculosis and lung cancer found by VRRU. The connection between the cases of cancer and the irradiation cannot be validated statistically.

[Acute left decompensation--significance of thoracic bed roentgenography for assessing pulmonary venous pressure (author's transl)].

25 thoracic bed x-ray films from 20 intensive-care patients were classified roentgenologically according to three degrees of severity of left decompensation, and compared with the end-diastolic pulmonary arterial pressure. Very good correlation was seen in 60% of the cases and a satisfactory agreement in 30%, whereas a discrepancy compared with haemodynamic parameters was observed in about 10% of the patients. Possibilities of explaining discrepancies are discussed within the framework of error analysis.
