The immediate motive for organizing the Belgrade symposium “Socialism and Culture” held in late 1969 were prohibitions. After June 1968 there were about forty political interventions in Serbia (while there had been none in the previous twenty years), considerably more than in other Yugoslav republics. The conclusion that was reached was that cultural life was provincialized and underdeveloped. The author in this paper extends the topic to a more global level since the intentions of the dialogue allowed for that. Data on Goli Otok, provided by Milovan Đilas, fit well with these facts. The Otok was the most drastic and dramatic prohibition in the entire history of the Second Yugoslavia. From both contemporary and presentday perspectives, the symposium may be interpreted as a cry for freedom. In this conversation, the members of the Belgrade wing of the Praxis group played a crucial role. Some of these same people would later participate in the events infamously marking the 1990s, above all the civil and religious wars. The Zagreb “headquarters” of Praxis was, on the contrary, never affected by the nationalist virus. Finally, arguments are proposed about Dobrica Cosic as the Serbian Faust, and the thesis of this writer being the Father of the Nation is contested.

Colorectal cancer with its frequency, high mortality rate as well as many etiological unknowns is a challenge to contemporary science. Finally, genetic information could be used in near future for prevention of colorectal cancer, its early diagnosis and selection for the most suitable hospital treatment. In this study, we analysed genetic alterations of tumor suppressor genes and the possibility of quick and efficient screening method for identification of colorectal cancer. The study consisted of 54 samples of tumor and surrounding healthy tissue of patients with colorectal cancer, which is clasificated according to Bethesda and Amsterdams criterias. The investigation showed that genetic alterations of tumor suppressor gene NM 23 were present in 19/35 (54,29%) samples, and tumor suppressor gene p53 in 18/35 (51,43%), APC in 18/35 (51,43%), DCC2 tumor suppressor gene in 12/35 (34,29%), tumor suppressor gene RB1 in 8 /35 (22, 86%) and DCC 1 in 10/35 ( 28,57%) tumor tissue.

Somatic mutations of MMR gene are not often present in HNPCC and in sporadic RER+ colorectal cancers. Complete studies were made according to Bethesda and Amsterdam Criteria, and 35 patients belonged to the group with sporadic colorectal cancer, and 9 patients belonged to HNPCC group. The results of our studies showed that there is no significant difference between RER phenotype of HNPCC and sporadic cancer (p>0,05) in regard to microsatellite status. It can be a good indicator that there are so called 'susspected' on HNPCC among sporadic cancers which were not detected yet. The reason for this was an incomplete familial history of illness of patients and as such it was selected as sporadic cancer. Microsatellite analysis together with medical and familial history of illness can be a successful instrument for efficient HNPCC identification. However, successful solving of this problem lies in making an accurate diagnosis in comparative findings, which can be provided by genetic and clinical tests.

SUMMARY CONFLICT OF INTEREST: none declared. Introduction Brucella endocarditis (BE) is a rare but severe and potentially lethal manifestation of brucellosis. Pre-existing valves lesions and prosthetic valves (PV) are favorable for BE. Case report We represent the case of a 46-year-old man who was treated at the Clinic for Infectious Diseases, Clinical Center of Sarajevo University, as blood culture positive (Brucella melitensis) mitral and aortic PV endocarditis. He was treated with combined anti-brucella and cardiac therapy. Surgical intervention was postponed due to cardiac instability. Four months later he passed away. Surgery was not performed.
