The reported incidence of sexually transmitted infections STIs in Germany is rising. For example, the number of new reported cases of syphilis rose from in to in This review is based on pertinent articles retrieved by a selective search in MEDLINE, and on guidelines and systematic reviews from Germany and abroad.
We discuss sexually transmitted infections presenting with genital, anal, Nice sexually transmitted infections powerpoint, or oral ulcers, urethritis, cervicitis, urethral or vaginal discharge, or genital warts. Acquired sexually transmitted infections elevate the risk of transmission of other sexually transmitted infections; thus, patients presenting for the diagnosis or treatment of any kind of sexually transmitted infection should be evaluated for others as well.
Factors impeding effective treatment include antibiotic resistance an increasing problem and the late diagnosis of HIV and HCV infections. Molecular genetic diagnostic techniques should be made widely available. Sexually transmitted infections are caused by a wide variety of bacteria, viruses, and parasites that are communicated from one human being to another primarily by vaginal, anal, Nice sexually transmitted infections powerpoint oral sexual contact.
Different sexually transmitted infections STIs can be present or be transmitted simultaneously, and the presence of any such infection increases the risk of contracting other types of STI. Sexually transmitted infections are often oligo- or asymptomatic. According to the World Health Organization WHOsexually transmitted infections are one of the five types of disease for which adults around the world most commonly seek medical help 1.
The current state of the data on the prevalence of sexually transmitted infections in Germany does not permit any reliable conclusions about infection rates, except for those of two diseases: Sexually transmitted infections can cause severe fetal and neonatal damage, genital neoplasia, and infertility. A number of diagnostic strategies and tests, of variable quality, are available for the individual pathogens.
According to the WHO, sexually transmitted infections are one of the five types of disease which adults around the world most commonly seek medical help. The diagnostic and therapeutic algorithms can generally be tailored to the leading clinical manifestations if the patient is symptomatic.
Thus, sexually transmitted infections can usefully be classified by their presenting features, as follows:. If the availability of diagnostic tests is limited, effective treatment can also be initiated without any testing on the basis of the clinical findings alone, if these are clearly typical of a particular sexually transmitted disease.
Asymptomatic infections are common, however, and only detectable by testing. The likelihood that an infection will be asymptomatic depends both on the site of infection and on the responsible pathogen. For example, the probability of asymptomatic rectal infection with C. The treatment of sexual partners is important as well. Bacterial infections and trichomoniasis "Nice sexually transmitted infections powerpoint" now be cured with systemic treatment 156.
Viral infections due to HIV, HSV, and human papillomaviruses cannot be cured, but they can be weakened or modulated with systemic treatment 156. Hepatitis B infections, scabies, pubic lice, cytomegalovirus infections, lymphogranuloma venereum, ulcus molle, and inguinal granuloma will not be discussed here. Infectious ulcers in the genito-anal region are commonly due to HSV. HSV infection is the most common sexually transmitted "Nice sexually transmitted infections powerpoint" that causes ulcers.
Herpes simplex virus persists in the human host for his or her entire lifetime. Painful vesicles may develop into erosions or ulcers that secrete a hyaline infectious fluid Figure 1. The ulcers generally heal completely in two to three weeks. HSV infection can manifest itself initially with regional lymphadenopathy and fever; on the other hand, it can also be asymptomatic. HSV infection can be transmitted by sexual contact including oral sex as well as perinatally from mother to child.
Persons with an acute HSV-1 infection should refrain from unprotected oral sex. Moreover, studies have shown that HSV-2 infection triples the risk of HIV infection through unprotected sexual intercourse e6. The virus can also be revealed by antigen-detection techniques, but these are much less sensitive.
Genital herpes infections are treated systemically with aciclovir, valaciclovir, or famciclovir; the dose depends on whether the episode is an initial infection or a recurrence, and on whether the patient is immunocompromised Table. In patients who have HSV infections that recur four or more times a year, long-term viral suppression therapy with aciclovir, valaciclovir, or famciclovir should be considered The treatment of sexual partners may be indicated 5.
Syphilis is caused by Treponema pallidum. Sentinel analysis in Germany revealed a fluctuating reported incidence of the Nice sexually transmitted infections powerpoint in the range of 1. There were reported cases inand in 7. Half of all infected persons develop a painless ulcer with an indurated edge ulcus durum after an average interval of Nice sexually transmitted infections powerpoint weeks; this heals in 4—6 weeks with or without treatment Figure 2 7. Painless lymphadenopathy develops regionally.
Hematogenous spread stage II; secondary syphilis leads to systemic symptoms arising six weeks to six months later, including fever, myalgia, bone and joint pain, transaminase elevation, and, typically, a maculopapular rash roseola syphilitica.
Treponemes are present in these skin lesions, which can therefore transmit infection by contact 7.
