Urethritis refers to inflammation of the urethra and is classified as gonococcal (caused by Neisseria gonorrhoeae) or nongonococcal in origin (most commonly caused by Chlamydia trachomatis, Mycoplasma genitalium, or Trichomonas vaginalis). The most common signs and symptoms include dysuria, mucopurulent urethral discharge, urethral discomfort, and erythema. Diagnostic criteria include typical signs, symptoms, or history of exposure in addition to mucopurulent discharge, Gram stain of urethral secretions showing at least two white blood cells per oil immersion field, first-void urinalysis showing at least 10 white blood cells per high-power field, or a positive leukocyte esterase result with first-void urine. ⋯ Repeat testing is not recommended less than three weeks after treatment because false-positive results are possible during this time. Patients treated for a sexually transmitted infection should have repeat screening in three months, with shared decision-making about future screening intervals. Patients treated for urethritis should abstain from sex for seven days after the start of treatment, until their partners have been adequately treated, and until their symptoms have fully resolved.

In 2018, approximately 2.8 million passengers flew in and out of U. S. airports per day. Twenty-four to 130 in-flight medical emergencies are estimated to occur per 1 million passengers; however, there is no internationally agreed-upon recording or classification system. ⋯ Coordinated communication with the pilot, any available ground-based medical resources, and flight dispatch is needed if aircraft diversion is recommended. In the United States, medical volunteers are generally protected by the Aviation Medical Assistance Act of 1998. There is no equivalent law governing international travel, and legal jurisdiction depends on the patient's and medical professional's countries of citizenship and the country in which the aircraft is registered.
