Early detection of malignant process in benign lesions of breast tumor by measurements of changes in structuredness of cytoplasmic matrix in circulating lymphocytes (SCM test) reinduced in vitro by specific tumor antigen.

Early detection is crucial for successful treatment of all types of cancer. The specificity and sensitivity of the current methods vary from 50% to 80%. The use of specific tumor antigens and cytometric technology has resulted in the development of a new procedure for the early detection of breast tumors.

[Stromal tumors of gastrointestinal tract: clinical and pathological features].

During the period 1991 till 1999, ten patients with primary stromal tumors of the gastrointestinal tract (stomach, duodenum, jejunum, ileum and rectum) were treated. Nine patients underwent radical resection and one patient had non-complete resection of the tumor. The median age of the group was 63 years for 7 male and 3 female patients.

[Primary peritonitis due to Streptococcus pyogenes].

Most infections causing by Streptococcus pyogenes are known to be putrid both in adults and children, for example laryngitis, impetigo, cellulitis, scarlet fever, septic shock, toxic shock syndrome etc. Their clinical importance relates to a number of causes: 1) about 20% of the population are S. pyogenes carriers; 2) the clinical course of infections is often severe or even fatal; 3) there is real danger of nosocomial outbursts; 4) a world-wide increase in both the rate and invasiveness of the microbe.
