It is characterized by inflammation of the cervical mucosa and submucosa. Pathogens that cause vaginal inflammation such as Trichomonas and Candida can cause inflammation of the cervicovaginal area. The common pathogens of acute cervicitis are Chlamydia trachomatis and Neisseria gonorrhoeae, both sexually transmitted, and also caused by Staphylococcus, Streptococcus and Enterococcus. Diagnostic points 1. Clinical manifestations. (1) Increased vaginal discharge, spotting bleeding or bleeding after sexual intercourse. (2) Itching of the vulva accompanied by lumbago and lower abdominal cramps. (3) Chlamydia trachomatis cervicitis is asymptomatic in 30% to 50% of infected patients and can persist for several years; the most serious complication is acute tubal inflammation with clinical manifestations of fever, general malaise, lower abdominal pain, uterine and adnexal tenderness, and yellow-green mucopurulent discharge. (4) Gonococcal infection is asymptomatic in half of female patients, sometimes with a small amount of vaginal discharge, mild pain and burning sensation in the vagina, spasmodic itching in the vulva, and systemic symptoms such as fever, malaise, and abdominal pain in a few patients. Gonococcal urethritis, usually onset 2-5 days after sexual intercourse, frequent urination, urinary urgency, painful urination, burning sensation and difficulty in urination, redness of urethral orifice, purulent discharge, vestibular gland may be red, swollen and painful to pressure. 2.Gynecological examination of the cervix is congested, edematous, erosion, and blood on palpation. 3.Auxiliary examinations. (1) Smear of cervical secretion: Gram stain more than 10 white cells in each oil microscope field. (2) Bacterial culture of vaginal secretion and drug sensitivity test. (3) Culture of vaginal secretion for Chlamydia or gonococcus and enzyme-linked immunosorbent assay. (4) Cervical port culture is the best method to diagnose gonorrhea. Treatment principle: select sensitive antibiotic treatment for the pathogen. 1, Chlamydia infection is commonly treated with tetracycline, erythromycin and chlortetracycline antibiotics, while treating sexual partners; 2, gonococcal infection is commonly treated with third-generation cephalosporins, quinolones and macromycin, advocating high dose and single administration.
