The five review topics in this issue highlight some of the key controversies in sexually transmitted infections (STIs), and their control.
The authors are from all corners of the world and work in different healthcare systems, but all have an awareness of the internationality of STIs, which do not conform to national boundaries.
A problem in one country can rapidly spread to other continents, requiring a world view of STI treatment and control, and international collaboration and support.
There are some major areas of concern: in men who have sex with men (MSM), there is a resurgent syphilis epidemic, hepatitis C in HIV-positive men has an annual incidence of transmission of 2–4% , and there is no decrease in HIV incidence in MSM; gonorrhoea has increased globally by 21% over 3 years  and multidrug, extensively drug-resistant and potentially untreatable

In 2013, based on data reported as of April 28, 2014, the rate of reported primary and secondary syphilis in the United States was 5.3 cases per 100,000 population, more than double the lowest-ever rate of 2.1 in 2000.
To characterize the recent epidemiology of syphilis in the United States, CDC analyzed data from the National Notifiable Diseases Surveillance System (NNDSS) for cases of primary and secondary syphilis diagnosed during 2005–2013 with a focus on states that reported the sex of sex partners during 2009–2012 to describe reported syphilis among gay, bisexual, and other men who have sex with men (collectively referred to as MSM).
During 2005–2013, primary and secondary syphilis rates increased among men of all ages and races/ethnicities across all regions of the United States.
Recent years have shown an accelerated increase in the number of cases, with the largest increases occurring among MSM. Among women, rates increased during 2005–2008 and decreased during 2009–2013, with different trends among different racial/ethnic groups.
Racial/ethnic disparities in reported syphilis persisted during 2005–2013, likely reflecting social determinants of health, such as socioeconomic status, that might contribute to the burden of syphilis in a community (1).
These findings underscore the need for continued syphilis prevention measures among MSM….

Antimicrobial drug resistance can hinder gonorrhea prevention and control efforts.
In this study, we analyzed historical ciprofloxacin resistance data and gonorrhea incidence data to examine the possible effect of antimicrobial drug resistance on gonorrhea incidence at the population level.
We analyzed data from the Gonococcal Isolate Surveillance Project and city-level gonorrhea incidence rates from surveillance data for 17 cities during 1991–2006.
We found a strong positive association between ciprofloxacin resistance and gonorrhea incidence rates at the city level during this period. Their association was consistent with predictions of mathematical models in which resistance to treatment can increase gonorrhea incidence rates through factors such as increased duration of infection.
These findings highlight the possibility of future increases in gonorrhea incidence caused by emerging cephalosporin resistance.

Of the chlamydia species that can cause infections in humans, C. trachomatis is responsible for lower urinary tract diseases in men and women. C. trachomatis infections are prevalent worldwide, but current research is focused on females, with the burden of disease and infertility sequelae considered to be a predominantly female problem.
However, a role for this pathogen in the development of male urethritis, epididymitis, and orchitis is widely accepted. Also, it can cause complications such as chronic prostatitis and infertility.
This review summarizes C. trachomatis infection in the male genitourinary tract, including urethritis, epididymitis, orchitis, and its complications, and addresses the microbiology, epidemiology, screening, clinical manifestations, diagnosis, and treatment.

Mycoplasma genitalium is a member of genital mycoplasmas, which is emerging as an important causative agent of sexually transmitted infections both in males and females. The advent of polymerase chain reaction and other molecular methods have made studies on M. genitalium more feasible, which is otherwise a difficult organism to isolate. Besides Chlamydia trachomatis, M. genitalium is now an important and established cause of non gonococcal urethritis (NGU) in men, more so in persistent and recurrent NGU. Multiple studies have also shown a positive association of M. genitalium with mucopurulent cervicitis and vaginal discharge in females as well. The evidences for M. genitalium pelvic inflammatory diseases and infertility are quite convincing and indicate that this organism has potential to cause ascending infection. Lack of clear association with M. genitalium has been reported for bacterial vaginosis and adverse pregnancy outcomes. Diagnosis of M. genitalium infections is performed exclusively using nucleic acid amplification tests (NAATs), owing to poor or slow growth of bacterium in culture. Although there are no guidelines available regarding treatment, macrolide group of antimicrobials appear to be more effective than tetracyclines. The present review provides an overview of the epidemiology, pathogenesis, clinical presentation and management of sexually transmitted infections due to M. genitalium.
