[The metastasis of prostatic cancer and the methods for its demonstration].

Metastasizing of prostate gland carcinoma is an essential and characteristic feature of its biological manifestation. The high capacity of prostate tumor cells to spread via lymphatic and blood stream explain the development of metastases in 52 to 80 per cent of patients presenting for primary diagnosis. Metastatic lesions are usually located in the lymph nodes (24.

[A comparative assessment between transrectal echography, venous urography, CAT and morphology in patients with prostatic carcinoma].

By incidence rate prostate gland carcinoma ranks second among all neoplastic diseases. As all tumorous neoformations, it is conspicuous for its progressive character. Clinical, laboratory and roentgen methods, thus far routinely used in practice, are hardly in a position to establish correct and accurate diagnosis alone.

[A comparative evaluation between transrectal echography, venous urography, computerized axial tomography and morphology in patients with prostatic carcinoma].

Prostate cancer is a rather common and severe disease in man. It affects the age beyond 50, a tendency being recently observed towards affecting subjects of younger age. In the early stage the symptoms are scarce and vague.

[AIDS patients--the surgical and deontological problems].

A case is reported of acquired immunodeficiency, in whom operative intervention was performed. A series of problems of surgical and deontologic aspect are raised, which ought to be solved without inducing mental trauma to the patients. Paralleling this, measures should be taken, to reduce to a minimum the risk of nosocomial infection to the medical staff.

[Cardiac tamponade from right ventricular rupture in severe lipomatosis].

A case of an 80 years old woman with II-degree obesity is presented. The patient showed no hemodynamic disturbances prior to her death despite bilateral cardiac overload causes by chronic pulmonary inflammatory processes and arterial hypertension. The rupture of the right ventricular cardiac wall with cardiac tamponade was due to the massive fatty infiltration of the cardiac wall and to the sharp increase of the hydrostatic pressure in the right ventricle in the course of pulmonary embolism.

[Fine-needle aspiration biopsy in the diagnosis of thyroid diseases].

On 105 patients with thyroid gland diseases thin needle aspiration biopsy was performed. The cytologic examinations proved to be of great importance for the diagnosis of thyroiditis and thyroid cancer. When lymphoid cells were found immunocytochemical examination was made additionally.

[Ultrastructure of asbestos-induced mesotheliomas].

Experimental mesotheliomas induced in albino rats by treatment with isometric crocidolite asbestos were studied by light and electron microscopy. The cellular structure of different types of neoplasms was examined. The ultrastructural investigation was carried out using both freshly-resected materials and those recovered from paraffin blocks.
