Recurrent candidal glans manifests as erythema in the glans area, which may have small pustules or papules on the surface. It may also present as localized edema of the glans mucosa with mildly desquamated edges, and may have papules and small pustules that expand around to form glans erosions. The erythema and edema at the urethral opening is often due to sexual contact. Anyone who has sexual intercourse with a woman suffering from Candida vaginitis can easily be infected; secondly, contact with indirect objects such as other people’s underwear, bath towels and baths, plus if the foreskin is too long, Candida multiplies and proliferates in the inner plate of the foreskin, the coronal sulcus and the glans. It has been found that men who have sexual contact with patients with Candida vaginitis have 69.4% of their genitals infected, and the detection rate of Candida on the penis of a husband with Candida vaginitis is four times higher than that of a husband without vaginitis. The following diseases are also common causes of erythema and edema in the urethra: 1. Urethritis Urethritis (urethritis) is an inflammation of the mucous membrane of the urethra, a common disease, mostly seen in women, clinically divided into acute and chronic, non-specific urethritis and gonorrheal urethritis, the latter two have similar clinical manifestations and must be identified on the basis of medical history and bacteriological examination. The latter two have similar clinical manifestations and must be differentiated on the basis of history and bacteriological examination. Clinically, the two often coexist and are collectively referred to as balanoposthitis (glans circumcision). The vaginitis in young girls is mostly coexisting with vulvovaginitis. Because of the poor development of the vulva and lack of estrogen in young girls, the vaginal epithelium has low resistance and is susceptible to infection. Common pathogens include Staphylococcus, Streptococcus and Escherichia coli, while Trichomonas or Candida can also cause infection. The pathogens can be transmitted through the clothes and bath tubs of sick mothers, caregivers or kindergarten children. It can also be caused by poor hygiene, unclean vulva, often contaminated by stool or direct contact with dirt. 4, pediatric Wright syndrome Wright syndrome (Reiters syndrome, RS) has three clinical features: namely urethritis, conjunctivitis, arthritis, so it is also called urethral, ocular, joint syndrome. Infections and genetic factors are associated with the development of this disease. Pediatric Wright’s syndrome is less common clinically. in 1916, a Prussian officer developed arthritis, conjunctivitis and urethritis after 8 days of abdominal pain and bloody stools. a few days later, the symptoms subsided, and 3 weeks later, urethritis and uveitis recurred. Dr. Wright recorded the process and later named the disease after him, calling it Wright’s syndrome.
