It causes urethritis, cervicitis, epididymitis, pharyngitis, proctitis, and pelvic inflammatory disease (PID) and can spread throughout the body to cause both localized and disseminated disease. Most commonly, the term gonorrhea refers to urethritis and/or cervicitis in a sexually active person. In the pediatric population, the importance of gonorrhea is 3-fold, as follows:
PathophysiologyNeisseria gonorrhoeae is a gram-negative, intracellular diplococcus that grows best in the laboratory in an environment rich in carbon dioxide. Organisms are spread by sexual contact and can also be vertically transmitted during childbirth. N gonorrhoeae has a predilection for columnar mucosal cells. The physiologic ectopy of the squamocolumnar junction onto the ectocervix in the adolescent female is one factor that causes particular susceptibility to this infection. FrequencyUnited StatesGonorrhea is the second most commonly reported infectious disease in the United States, after chlamydia. Actual incidence is difficult to determine due to high rates of asymptomatic carriage, as well as underreporting; however, in 2005, 339,593 cases were reported in the United States (up slightly from 2004).1 The national average is 115.6 cases per 100,000 population, with considerable state-to-state variation.2 The rate is up slightly from 2004, when it was at its lowest level since 1941. The estimate of total cases is approximately 700,000 cases per year. In children who have been sexually abused, rates of recovery of gonorrhea range from 1-30%. In female adolescents who are sexually active, asymptomatic carriage of gonorrhea occurs in 1-5%. Within the United States, carriage rates highly depend on the geographical area, the racial and ethnic group, and sexual preferences. The South-Eastern States have the highest rates of infection; the rates in the midwest and northeast are much lower. Rates of infection range from about 250 cases per 100,000 population in Mississippi to 8.5 cases per 100,000 population in Idaho. The Centers for Disease Control and Prevention (CDC) has a campaign (Healthy People 2010) that targets an incidence rate of 19 cases per 100,000 population. Maine, Vermont, Wyoming, New Hampshire, Montana, and Idaho are the only states currently exceeding that target. See Media file 1. InternationalDisease rates are unknown for most developing countries. In much of Western Europe, rates approximate those in the United States. Mortality/MorbidityWhen untreated, gonorrhea may progress locally to cause PID in females, epididymitis and orchitis in males, and sterility in both sexes. It can also spread to cause septic arthritis, perihepatitis (Fitz-Hugh-Curtis syndrome), and disseminated gonococcal infection (DGI). In newborns, vertical transmission can cause conjunctivitis, known as ophthalmia neonatorum, and blindness, if untreated. Oral sex with an infected partner can result in pharyngitis, and, similarly, anal infection can arise from anal sex or local spread from a vaginal source. PID often causes decreased fertility and can lead to tubo-ovarian abscess and, rarely, tubal perforation with peritonitis and death, especially if recurrent. Females with recurrent PID have high rates of ectopic pregnancy and infertility (approximately 8% after 1 episode, 20% after 2 episodes, and 40% after 3 or more episodes). RaceFrequency is increased among individuals of lower socioeconomic status and among minorities of any population because of decreased access to diagnosis and treatment. Lack of adequate care (ie, education, diagnosis, and treatment) leads to increased transmission rates. Sex
AgeThe highest incidence in the United States is among persons aged 15-24 years. This is likely due to the following:
CLINICALHistoryThe incubation period usually is 2-7 days after exposure to an infected partner.

Proper education may be more effective than simplistic instructions to avoid sex, especially in the teenaged population. Teenagers involved with abstinence-only campaigns have unchanged STD rates and disproportionately acquire anal and oral infections, rather than vaginal infections (the perception is that if an activity is not vaginal sex, it is not sex).
The discussion of responsible sexual behavior should not be limited or withheld because of personal religious or moral views because these may not be shared by the patient and teenagers are notorious for sexual experimentation; evidence suggests that this limited discussion does the teenage population a huge disservice. This advice is especially pertinent in states where sexual education is almost nonexistent in the school system because of abstinence-only teaching, which is misleading and factually inaccurate.
Although the most effective prevention is abstinence from sex, this is oftentimes an unrealistic expectation, especially in the teenaged population; in fact, 88% of teenagers who pledged abstinence in middle and high school still engaged in premarital sex. Moreover, they tend to have riskier, unprotected sex because of their lack of education; those who pledge before having sex have a 33% higher prevalence rate of STDs than those who had sex and then retrospectively pledged, with nonpledgers falling in between. This is despite a lower number of partners and an older age at first intercourse in pledgers.
Of course, abstinence should be explained to be the best option, but a more practical expectation is abstinence from sex with someone known or suspected of having an STD until treatment is obtained and completed. In light of the difficulty in knowing a potential partner's sexual history (or honesty), strongly recommend the use of condoms as a reasonable alternative to abstinence.
Pledgers are actually less likely to be aware of their STD status and are less likely to seek testing, even if their STD rates are similar overall (again highlighting a lack of appropriate sexual education). Stress that oral or anal sex can also transmit disease.
Patients should also be counseled about the additional risks of unprotected sex, such as the acquisition of more serious or lifelong infections such as herpes, hepatitis B and HIV, and, of course, about the risks of pregnancy. The emotional aspect of sexual relationships may also need to be addressed, especially in teenage girls. Teenagers are vulnerable in that they are sexually mature but not yet emotionally mature.
Prevention of neonatal disease is with the use of silver nitrate 1% eye drops or 1% tetracycline or 0.5% erythromycin ophthalmic ointment within 1 hour of birth.
