551. Differential diagnosis between bone metastases and osteomalaciaBranko Zakotnik, Simona Borštnar, Tadeja Movrin, Boris Jančar, Andreja Zidar, 1996, original scientific article Abstract: In oncology the diagnosis of skeletal metastases is a frequent one, in infact so frequent that other diagnoses such as metabolic bone diseases affecting patients with cancer may be overlooked. In our report two cases of osteomalacia referred to an oncologist are presented; in both of them the diagnosis of diffuse bone metastases of unknown origin was suspected. The differential diagnosis is discussed and the importance of bone marrow biopsy using Yamshidi needle for diagnosis of metabolic bone disease is emphasized.

552. Advantages and disadvantages of hormone replacement therapySonja Bebar, Marjetka Uršič-Vrščaj, 1996, review article Abstract: In the developed countries, more than 30% of female population is in the postmenopusal period of their life. Approximately one third of these present with severe clinical menopausal symptoms, such as hot flushes, sleeplessness, night sweats, and depression. Many women search medical help. By means of hormone replacement therapy (HRT), these problems can be either completely eliminated or alleviated in 90% of women. The suspected association between HRT and risk of carcinoma should be ignored, however. While estrogens in combination with progestogens exert a protective effec against ovarian and endometrial carcinomas, a possible correlation between HRT and breast cancer has not been fully explained yet. Nevertheless, some published reports have indicated a slightly increased risk of breast cancer after a prolonged use of HRT.

553. Prognostic value of staging laparotomy in supradiaphragmatic clinical stage I and II Hodgkin's diseaseMarjeta Vovk, Tatjana Šumi-Križnik, Marija Jenko-Fidler, Gabrijela Petrič-Grabnar, Marinka Kremžar, Janez Novak, Mojca Senčar, Branko Zakotnik, Alenka Vodnik-Cerar, Branimir Jakšić, 1996, original scientific article Abstract: In the period 1974-1989, 219 patients with supradiaphragmatic clinical stage I and II Hodgkin's disease were treated at the Institute of Oncology in Ljubljana; of these 95 (43%) patients underwent staging laparotomy. Of laparotomized patients, those with pathological stage III-IV, and of non-laparotomized, those with unfavorable prognostic factors (B-symptoms, bulky mediastinum) received chemotherapy: the remaining patients were treated by irradiation. No statistically significant difference in the survival and disease-free survival between laparotomized and nonlaparotomized patients could be found.

554. Gastric emptying in rats with gastroduodenal disease induced by N-methyl-N-nitro-N-nitrosoguanidine and alcoholDražigost Pokorn, Anton Cerar, 1996, original scientific article Abstract: The rate of gastric emptying was measured with a dye dilution technique in rats treated with N-methyl-N-nitro-N-nitrosoguanidine and alcohol. Gastric emptying was compared in rats with gastroduodenal inflamatory diseases and gastroduodenal neoplasms, and in those without gastroduodenal disease. Gasttric emptying was found to be significantly increased following the intragastric injection of liquid meal in rats with gastroduodenal diseases as opposed to the control group of healthy rats. These findings suggest than an increased gastric emptying of liquids can be explained by abolition on the relaxation of the gastric wall in rats with gastroduodenal diseases.
