RESUMO
BACKGROUND: Chlamydia trachomatis causes the most prevalent bacterial Sexual Transmitted Infection. In pregnant women, untreated chlamydial infections are associated with abortions, premature rupture of membranes, postpartum endometritis, low birth weight and transmission to the newborn. In Córdoba, Argentina, there is little knowledge about the prevalence of Chlamydia trachomatis in women in their third trimester of pregnancy, so, the aim of this study was to evaluate Chlamydia trachomatis prevalence and genotypes present in Cordovan pregnant women with different age and socioeconomic status. METHODS AND FINDINGS: Design: prospective study. Settings: Women population from Cordoba city, Argentina. Population: Pregnant women having 35 to 37 weeks of gestation. Methods: Five hundred and nine cervical swabs were collected. Each sample was subjected to DNA extraction and PCR for Chlamydia trachomatis using primers NRO/NLO and CTP1/CTP2. Positives samples were sequenced to determine genotype. Main outcome measures: Demographic data of the patients were collected to detect a population at risk for this infection. RESULTS: A prevalence of 6.9% (35/509) for Chlamydia trachomatis infection was detected, with 32/295 and 3/214 from pregnant women with low or better economic resources respectively (p = 0,0001). Results showed a significantly increased rate of 11.6% (30/258) in women under 25 years compared with 2% (5/251) in patients over that age (p = 0,00003). Genotype E was the most prevalent. CONCLUSIONS: With these results, we can say that pregnant women under 25 years old and low economic resources are one of the populations in which the screening programs of Chlamydia trachomatis should focus.

BACKGROUND: Most studies of human papilloma virus (HPV) are aimed at the natural history of the infection and its relation to cancer; however, there are few studies to assess knowledge of the general population. Our aim was analyze the degree of knowledge of Argentinians about HPV infection and its prevention. MATERIALS AND METHODS: We conducted a voluntary, anonymous and non-binding survey with 27 multiple-choice items, in twelve private and public establishments, selected to include a broad population in terms of education, age and gender. The survey consisted of three sections: individual characteristics of the volunteer, HPV infection basic knowledge, its prevention and the virus relationship with other cancers. RESULTS: One thousand two hundred ninety seven volunteers aged 18 to 80 participated. The total number of correct answers was 45.1%. The correct answers for relationship HPV and cervical cancer was 62.1%. Almost 55% did not know about types of HPV that the vaccines for protection. Statistical analysis showed that women, single people, workers, the better educated, those who have had a STDs or HPV and receiving information through medical or educational establishments had greater knowledge of the topic. Only 0.2% of participants answered all questions correctly. CONCLUSIONS: Knowledge plays an important role in health care and the deficiency found in our population could influence the success of the measures taken in the fight against cervical cancer. In this regard, we believe it would be appropriate, not only to emphasize early diagnosis and vaccine implementation, but also incorporate new communication strategies, facilitating reception of accurate and precise information by all strata of society.
