The authors performed xerosialography on 41 patients with various diseases of the salivary glands. In 38 patients this provided positive information. Each of eight submandibular sialograms was abnormal; of the 33 parotid examinations, three benign salivary tumours could not be demonstrated radiologically. Xeroradiography is a useful method for the examination of the major salivary glands. It is superior to the traditional film method.

The authors carried out comparative examinations on 30 patients in order to determine whether xeroradiography had any advantages over film techniques in the examination of the soft tissues of the extremities. The xerograms show fatty degeneration of muscle fibres margins of individual muscles, calcification, oedema and so on, more clearly and are therefore of more value in diagnosis. The saving in time, using xerograms, is significant and conventional photo-copies can be obtained without logetronics.

The Fibor-Adeno-Lipoma is a rarely seen benign lesion of the breast. The encapsulated tumor is smoothly outlined. The capsule can be well visualized by mammography. The lesion contains different amount of fibroglandular tissue. In that way the mammographic appearance is characteristic and diagnosis becomes easy. The authors discuss the clinical and radiological appearance of the Fibro-Adeno-Lipoma on the basis of 7 cases.

The authors report on their four years' experience in oncologic mass examinations focused on the age group above 30. After 43980 serial examinations, they performed mammography in 3082 women with mammary cancer risk. 156 operations were performed, and 33 histologically established cases of mammary carcinoma were recorded, with 21 early-stage cases. Of 21 occult tumors, 18 did not manifest any metastases. Thanks to the epidemiologic questionnaire, 10 mammary cancer patients were registered. The score of confirmed findings exceeded quantitatively, and, especially, qualitatively, the mammary carcinoma morbidity of the region. The results prove the feasibility of the combined method. The major part of the population did not appear for mass examination. The advanced stage of the 55 cases of breast cancer belonging to this group, as well as that of the 10 cases of which became manifest during the examination interval, would indicate that much is to be said for a more effective health promotion campaign among the population.

The authors have demonstrated subcutaneous calcification which is characteristic for pseudo-pseudo-hypoparathyroidism (pph) and which is best shown by xero-radiography. If the presence of pph is suspected, or if it needs to be distinguished from some other condition, it is valuable to obtain xerograms of the soft tissues of the extremities. In pph the subcutaneous calcification is in all probability derived from the skeleton.

For diagnosing lesions of cervical intervertebral disks, pneumomyelography is carried out in addition to diskography in cases with an indication for surgery. The application of xeroradiography in pneumomyelography is discussed for the first time. In contrast to the conventional X-ray film technique, xeroradiograms yield shraper contours at the gas/tissue interface.
