Identification of sentinel lymph node in stage I-II breast cancer with lymphoscintigraphy and surgical gamma probe: comparison of Tc-99m MIBI and Tc-99m sulfur colloid.

Aim: To evaluate the efficacy of the surgical gamma probe (SGP) after peritumoral injection of Tc-99m MIBI and filtered Tc-99m sulfur colloid (SC) in sentinel lymph node (SLN) detection in stage I and II breast cancer for deciding on the need for axillary dissection.

Materials And Methods: Thirty patients with stage I-II breast cancer had peritumoral injection of Tc-99m MIBI (74 MBq/0.2 mL [2 mCi/0.

Evaluation by immunofluorescence of the urinary bacteria, of the therapy effectiveness in urinary infections.

The therapy effectiveness in urinary infections (UI) was investigated in 27 patients by the test of immunofluorescence of the urinary bacteria (IFUB) in relationship with bacteriuria, various other biologic investigations and tests of the immune response. The study revealed a complex involvement of the immune mechanisms in the UI occurrence and persistence, as well as a parallelism between the mechanisms of cellular and humoral immunity in some of the patients. The IFUB test could reveal the eventual germ persistence at the renal parenchyma level even in the absence of significant bacteriuria, thus suggesting the necessity of a long term suppressive therapy in such cases.

[Early cirrhosis, an early modality of the evolution of acute hepatitis. The clinico-biological, immunological and morphological aspects].

A group of 12 patients with recent acute hepatitis (8/86 with HVB and 4/22 with alcoholic hepatitis) had a rapid evolution (under 2 years) towards hepatic cirrhosis (early H.C.).
