In October 2008, the US EPA reduced the allowable lead level by a factor of ten to 0.15 micrograms per cubic meter of air, giving states five years to comply with the standards. The European Unions Restriction of Hazardous Substances Directive limits amounts of lead and other toxic substances in electronics and electrical equipment. In some places, remediation programs exist to reduce the presence of lead when it is found to be high, for example in drinking water. As a more radical solution, entire towns located near former lead mines have been "closed" by the government, and the population resettled elsewhere, as was the case with Picher, Oklahoma, in 2009. Removing lead from airplane fuel would also be useful. Screening
Screening may be an important method of prevention for those at high risk, such as those who live near lead-related industries. The USPSTF has stated that general screening of those without symptoms include children and pregnant women is of unclear benefit as of 2019. The ACOG and APP, however, recommends asking about risk factors and testing those who have them. Education
The education of workers on lead, its danger and how its workplace exposure can be decreased, especially when initial blood lead level and urine lead level are high, could help reduce the risk of lead poisoning in the workplace. Treatment
The mainstays of treatment are removal from the source of lead and, for people who have significantly high blood lead levels or who have symptoms of poisoning, chelation therapy.
Urethritis is the inflammation of the urethra. The most common symptoms include painful or difficult urination and urethral discharge. It is a commonly treatable condition usually caused by infection with bacteria. This bacterial infection is often sexually transmitted, but not in every instance; it can be idiopathic, for example. Some incidence of urethritis can appear asymptomatic as well. Symptoms and signs
Symptoms vary based on the cause of the diseases. For infectious causes of urethritis, symptoms may start a few weeks to several months after infection. Non-infectious causes of urethritis commonly show symptoms after a few days. Common symptoms include painful urination, continuous urge to urinate, itching and, urethral discharge. Additional symptoms vary based on assigned sex at birth. AMAB (assigned male at birth) individuals may experience blood in the urine or semen, itching, tenderness, or swelling of the penis, enlarged lymph nodes in the groin area, and/or pain with intercourse or ejaculation. AFAB (assigned female at birth) may experience abdominal pain, pelvic pain, pain with intercourse, or vaginal discharge. Non-gonococcal urethritis typically does not have noticeable symptoms in AFAB individuals, however, the infection can spread to parts of the reproductive system. Complications
Serious, yet rare complications associated with Neisseria gonorrhea, may include penile edema, abscessed tissue surrounding the urethra, urethral strictures such as scarring, and penile lymphangitis. If left untreated, the bacteria that cause non-gonococcal urethritis can lead to various complications. In individuals assigned male at birth, complications can lead to epididymitis, reactive arthritis, conjunctivitis, skin lesions, and discharge.
