[Survey of sexually transmitted diseases in the region of Rio Cuarto]

Sexually transmitted diseases (STD) are acquired mainly through sexual intercourse, being one of the most frequent groups of infectious diseases worldwide and consequently an important public health problem. The aim of this paper was to determine the current state of STD and to compare different diagnostic methods in the population studied. A total of 1060 samples from vaginal flows, endocervical material and urethral discharge were studied during 3 years. Of the total samples, 583 were positive, 493 in women and 90 in men. Microorganisms found in women were: Gardnerella vaginalis (39.3%), Candida albicans (21.1%), Trichomonas vaginalis (17.3%), Candida trachomatis (11.3%), Neisseria gonorrhoeae (3.2%): Mycoplasma hominis and Ureaplasma urelyticum (6.5%) and Treponema pallidum (1.4%), the associations found were, Gardnerella vaginalis with Trichomonas vaginalis 5.5%; Gardnerella vaginalis with Candida albicans 4.9%; Trichomonas vaginalis with Neisseria gonorrhoeae (2.2%) and Gardnerella vaginalis with Chlamydia trachomatis (1.9%). In men, gonococcal urethritis (UG) represented 37.7% non UG 55.6% and Treponema pallidum 6.7%. These results indicate a decrease in sifilis and in UG when compared to previous studies showing that gonococcal cervicitis had also decreased. We found an important increase in the prevalence of urethritis and non gonococcal cervicitis in agreement with world statistics which consider these diseases as the most common venereal ones. It is necessary to increase the search for Chlamydia trachomatis in pregnant women due to vertical transmission. It should be noted that, in spite of certain fluctuations, the incidence of the STD in our area is still unacceptably high.
