Use of angioscintigraphy in the diagnosis of malignant tumors of the liver.

Dynamic hepatic angioscintigraphy, a method of estimation and follow up of the double (arterial and portal) circulation in the liver, was performed in association with static liver scanning in 20 patients with suspicion of primary or secondary tumors of the liver, and in 5 healthy controls, after administration of 113min colloid. This procedure allowed confirmation of primary neoplastic tumors of the liver in 3 patients and of hepatic metastases in 5. The method supplies additional diagnostic information in malignant tumors of the liver and reduces the irradiation of the patients by using a single radiopreparation.

[Normal and pathological conjunctival cytology].

The authors propose a cytological study of the conjunctiva, using the conjunctival print method, at patients with different (degenerative inflammatory and tumoral) ocular diseases. The conjunctival print method is less traumatic and contributes, together with the data supplied by the clinical examination, in elucidating the etiological diagnosis and orientating therapeutical conduct. Without representing a pathognomonic exam, the cytological study of the conjunctiva brings important diagnosis data, but also data concerning the evolution, so it is recommended to be done in the dynamics.

Immunochemical assays for an early diagnosis of endemic nephropathy.

Comparative studies aiming at the detection of certain tubular protein elements by means of Ouchterlony's immunodiffusion, in parallel with lysozyme and guanase assays, were carried out in the unconcentrated urines of 746 subjects, of whom 655 apparently healthy inhabitants (mostly children) from a region with endemic nephropathy (EN) and from Bucharest, as well as 91 adults with EN or various other diseases with renal involvement. The presence of light chains, of lysozymuria exceeding 2 microgram/ml, of beta2 microglobulin and of guanase in the urines of children and adults from the endemic area was significantly more frequent than in the control groups. These immunochemical changes are hence considered as valuable criteria for the detection of EN prior to the uremic stage. They should be looked for, first and foremost, in the young relatives of patients with this disease. In the stage of nitrogen retention the diagnostic value of these tests is reduced, since the same changes can also be found in the urines of patients suffering from other diseases with renal involvement, which show nitrogen retention as well.
