Background: Sexual transmitted infections are a main cause of morbidity, being a public health problem due to its reproductive complications, mostly observed in teenagers and young adults. The purpose of this study was to evaluate sociodemographic factors and risky behaviours associated with sexual transmitted infections acquisition and to assess personal awareness of risky behaviour and the knowledge about Chlamydia trachomatis infection between foreign exchange students in Portugal., Material and Methods: The main instrument for data collection was a questionnaire, applied to foreign students in university exchange in Portugal, during the years 2012/2013, 2013/2014 e 2014/2015 Results: Three hundred and thirty eight (338) questionnaires were evaluated, being 58.3% female students, aged between 17 and 30 years old. Mean age for the beginning of the sexual activity was 17.5 years old and the mean number of lifetime sexual partners was 6.9. Concerning the answers given: 11.8% mentioned a sexual relationship with the same gender, 9.5% mentioned that they have never done oral sex and 29% assumed they had practiced anal sex; 82.1% mentioned alcohol/drugs consumption; 21% did not know that Sexual transmitted infections can be transmitted through oral sex and 42.3% did not recognize Chlamydia trachomatis as an Sexual transmitted infections agent., Discussion: Although sexual transmitted infections can affect individuals of all ages, races and sexual orientation, various demographic, social and behavioral factors have revealed influence in their prevalence rates., Conclusion: Despite knowing about sexual transmitted infections, these students maintain sexual risky behaviours, mainly early age for starting sexual activity, multiple sexual partners and the absence of protection during sexual activities.

The increase in sexually transmitted infections (STIs) in Europe and the USA, especially among men who have sex with men (MSM) and transgender women (TW), has raised concerns and prompted the exploration of doxycycline prophylaxis as a potential intervention. Doxycycline prophylaxis can be administered either as a daily 100 mg dose (DoxyPrEP) or a single 200 mg dose post-sexual activity (DoxyPEP). Recent clinical trials, primarily focusing on higher-risk groups, have shown reductions of approximately 70% in syphilis and chlamydia infections and conflicting results regarding gonorrhea infection (up to 50%). Despite these advancements, the effectiveness of doxycycline prophylaxis among women has not been established and this strategy raises concerns about community acceptability, adverse events, safety, antimicrobial resistance, microbiome disruption, and cost-effectiveness. Ongoing clinical trials and agent-based models aim to address these uncertainties to predict the impact on a population level and on specific groups. This review aims to assess the existing data of doxycycline STI prophylaxis, identify knowledge gaps, and synthesize existing literature and guidelines about the current recommendations.

As such, and considering that the disease duration was unknown, three doses were administered.1-3 Herein, we present a unique case of nodular syphilis in an 83-year-old immunocompetent patient. Negative immunochemistry studies can occur due to longstanding secondary syphilis or previous antibiotic treatment regimens.1,5 Gold-standard treatment for secondary syphilis consists in a single intramuscular injection of PB.

Introduction: Partner notification plays a key role in the epidemiological control of the increasingly frequent sexually transmitted infections (STI). Material and Methods: One hundred consecutive patients from the Venereology consultation of the Santa Maria Hospital in Lisbon answered a questionnaire on notification of partners. Results: Forty three of the individuals had a previous history of STI, 25 of which had a previous diagnosis of HIV infection. Sixty-four patients said that they informed their partners about the diagnosis. Of those who did not inform, 50% no longer have contact with the partners and 36% consider that was not important. Regarding partner notification methods: 98% found appropriate to bring a leaflet about the disease to the partners; 72% would agree to give a consultation authorization to the partner, 58% considered that taking the medication directly to the partner would be an option, 58% thought appropriate that the partner's family doctor call them for a consultation; and 42% considered appropriate to send an email or mobile message. Discussion: The high percentage a previous STI diagnosis suggests this is a group of individuals with the highest risk of STI transmission. A high percentage (36%) of those who did not inform the partners felt that it would not be important, which may reveal a failure of communication from the health professional. The method considered the most suitable was passive reporting. Conclusion: It is necessary to improve effective partner notification at it is highly needed to reduce the incidence of STI.

Trichomonas vaginalis and Mycoplasma genitalium: age-specific prevalence and disease burden in men attending a sexually transmitted infections clinic in Amsterdam, the Netherlands. Comparative prevalence of infection with Trichomonas vaginalis among men attending a sexually transmitted diseases clinic. From our clinic, TV infection in men seems to be less frequent than in the published literature.2,5 This is not related to diagnostic methods, as we routinely conduct multiplex PCR for STI diagnosis and screening.

This study reports the case of a 15-year-old male patient with extensive anal inflammation, cobblestone-like mucosa and areas of ulceration, loose bloody stool and weight loss for 8 weeks, suggestive of inflammatory bowel disease. Genital lesions of syphilides were later observed and Venereal Disease Research Laboratory test was positive, thus benzyl penicillin treatment was prescribed with total resolution of genital and bowel symptoms.
