Men who have sex with men (MSM) have increased rates of human immunodeficiency virus (HIV) infection and sexually transmitted diseases (STDs) compared with demographically matched controls. The reasons for the disproportionate infection burden are complex, including biological, behavioral, and sociocultural factors. HIV and syphilis may often be coprevalent among MSM. The use of nucleic acid amplification testing has enhanced the ability to detect frequently asymptomatic gonococcal and chlamydial infections of the rectum and other sites. Lymphogranuloma proctitis outbreaks among MSM were noted in the developed world several years ago but have not been common recently. MSM are at increased risk for viral hepatitis and anal human papillomavirus disease. Preventive interventions include vaccination for the former and anal cytologic screening for the latter. Because of the diverse ways in which MSM may be exposed to STDs, it is essential for clinicians to obtain a thorough sexual history in a culturally competent manner.

Sexually Transmitted Infections Among Women Who Have Sex With Women

Clinical Infectious Diseases Dec.2011 V.53 N.12 Suppl.3  S84-S91

Women who have sex with women (WSW) are a diverse group with variations in sexual identity, sexual behaviors, sexual practices, and risk behaviors. WSW are at risk of acquiring bacterial, viral, and protozoal sexually transmitted infections (STIs) from current and prior partners, both male and female. Bacterial vaginosis is common among women in general and even more so among women with female partners. WSW should not be presumed to be at low or no risk for STIs based on sexual orientation, and reporting of same-sex behavior by women should not deter providers from considering and performing screening for STIs, including chlamydia, in their clients according to current guidelines. Effective delivery of sexual health services to WSW requires a comprehensive and open discussion of sexual and behavioral risks, beyond sexual identity, between care providers and their female clients.

Neisseria gonorrhoeae Resistant to Ceftriaxone and Cefixime, Argentina

Emerging Infectious Diseases June 2016 V.22 N.6

Letter

To the Editor:

Antimicrobial resistance in Neisseria gonorrhoeae is increasing globally. In recent years, gonococcal strains with resistance to the extended-spectrum cephalosporin (ESC) ceftriaxone have been reported from many countries (1). In South America, 7 ceftriaxone-resistant strains (MICs >0.25 μg/mL) were reported from Brazil in 2007; however, these isolates have not been characterized (2). Emergence of cephalosporin-resistant gonorrhea would substantially limit treatment options and represent a major public health concern. We report an N. gonorrhoeae isolate in Argentina that was resistant to ceftriaxone and cefixime…..

Zika Virus

In 1947, a study of yellow fever yielded the first isolation of a new virus, from the blood of a sentinel rhesus macaque that had been placed in the Zika Forest of Uganda.1 Zika virus remained in relative obscurity for nearly 70 years; then, within the span of just 1 year, Zika virus was introduced into Brazil from the Pacific Islands and spread rapidly throughout the Americas.2 It became the first major infectious disease linked to human birth defects to be discovered in more than half a century and created such global alarm that the World Health Organization (WHO) would declare a Public Health Emergency of International Concern.3 This review describes the current understanding of the epidemiology, transmission, clinical characteristics, and diagnosis of Zika virus infection, as well as the future outlook with regard to this disease…

Technological Solutions to Address Drug-Resistant Neisseria gonorrhoeae

Emerging Infectious Diseases May 2016 V.22 N.5

Letter

To the Editor: Since the 1930s, Neisseria gonorrhoeae has become resistant to drugs in every class of antimicrobial therapy used to treat it. We read with interest the article by Martin et al. about trends in Canada on N. gonorrhoeae susceptibility to third-generation cephalosporins, the only class of antimicrobial drugs to which most N. gonorrhoeae strains remain susceptible (1). We find the reported decrease in cefixime- and ceftriaxone-reduced susceptibility during 2010–2014 encouraging, but remain concerned about a threat from drug-resistant and untreatable N. gonorrhoeae infections: a similar downward trend in the United States reversed in 2014 (2). That divergence demonstrates the limited reliability of surveillance data…..

Male-to-Male Sexual Transmission of Zika Virus — Texas, January 2016

MMWR Weekly April 15, 2016 V.65 N.14 P.372–4

Collins, Colorado; 5Epidemic Intelligence Service, CDC.

Zika virus infection has been linked to increased risk for Guillain-Barré syndrome and adverse fetal outcomes, including congenital microcephaly. In January 2016, after notification from a local health care provider, an investigation by Dallas County Health and Human Services (DCHHS) identified a case of sexual transmission of Zika virus between a man with recent travel to an area of active Zika virus transmission (patient A) and his nontraveling male partner (patient B). At this time, there had been one prior case report of sexual transmission of Zika virus (1). The present case report indicates Zika virus can be transmitted through anal sex, as well as vaginal sex. Identification and investigation of cases of sexual transmission of Zika virus in nonendemic areas present valuable opportunities to inform recommendations to prevent sexual transmission of Zika virus.

The current outbreak of Zika virus (ZIKV) infection has been associated with an apparent increased risk of congenital microcephaly. We describe a case of a pregnant woman and her fetus infected with ZIKV during the 11th gestational week.

The fetal head circumference decreased from the 47th percentile to the 24th percentile between 16 and 20 weeks of gestation. ZIKV RNA was identified in maternal serum at 16 and 21 weeks of gestation.

At 19 and 20 weeks of gestation, substantial brain abnormalities were detected on ultrasonography and magnetic resonance imaging (MRI) without the presence of microcephaly or intracranial calcifications. On postmortem analysis of the fetal brain, diffuse cerebral cortical thinning, high ZIKV RNA loads, and viral particles were detected, and ZIKV was subsequently isolated….
