Syphilis is experiencing a resurgence in cases, while gonorrhea has become increasingly resistant to treatment, posing significant challenges for public health efforts. New and potentially serious(STDs) like Mycoplasma genitalium have also been identified as emerging threats.
A study found that medically supervised male circumcision significantly reduces the risk of acquiring genital herpes (HSV-2) and human papillomavirus (HPV), but has no effect on syphilis. Circumcision was also associated with a 28% lower risk of HSV-2 infection and a 35% reduced prevalence of HPV.
Researchers identified sequence variations in the ARP gene that allow differentiating venereal syphilis from non-venereal Treponema pallidum subspecies. The findings have significant clinical, epidemiological and evolutionary implications.
A recent study found that state Medicaid statistics significantly underreported prenatal syphilis screening rates, with only half of eligible women having evidence recorded. The study suggests that analyses relying solely on Medicaid data may not provide an accurate picture of screening rates nationwide.
The resurgence of syphilis in high-income countries has left many doctors unfamiliar with the disease's manifestations. The authors conclude that renewed training is necessary for health-care professionals, particularly in addressing increases among men who have sex with men and some high-risk heterosexual couples.
A comprehensive genetic analysis supports the 'Columbian theory' of syphilis's origins, suggesting the pathogen was introduced to Europe by Columbus and his men. The study found that the venereal syphilis-causing strains originated most recently and were closest relatives to strains causing yaws in South America.
Researchers found that rapid syphilis screening during pregnancy can prevent congenital syphilis cases and improve child survival. Lithium also showed promising results in a mouse model of spinocerebellar ataxia, a devastating neurodegenerative disorder with no existing treatments.
Researchers found that integrating rapid syphilis testing into prenatal HIV testing programs in Haiti can prevent over 2,000 cases of stillbirth, neonatal death or congenital syphilis. The approach proved to be the best strategy due to its simplicity and ease of administration.
Syphilis rates among US gay and bisexual men have seen a significant increase, rising by 19% between 2000 and 2003. The rates jumped by 62% among men, with 62% of those infected being gay or bisexual, while rates among women continued to slide.
A rapidly increasing syphilis epidemic is sweeping China, with infection rates rising from less than 0.2 cases per 100,000 people in 1993 to 6.5 cases per 100,000 in 1999. The study attributes the surge to economic reforms and globalization, as well as changes in social practices and healthcare costs.
