Non-gonococcal urethritis (cervicitis): Myth 1: Mycoplasma positive is diagnosed as non-gonococcal urethritis (cervicitis) Knowledge: non-gonococcal urethritis (cervicitis) that is, there is a urethritis (cervicitis), but the secretion smear or culture can not find gonococcus of a sexually transmitted disease. It is mainly caused by Chlamydia trachomatis (CT), followed by Mycoplasma, and to a lesser extent viruses and fungi. Mycoplasmas associated with genitourinary tract infections include Mycoplasma urealyticum (Uu), Mycoplasma hominis (MH) and Mycoplasma genitalium (MG). Foreign reports of sexually mature asymptomatic female Uu isolation rate of 40%-80%, normal male urethra Uu isolation rate of 34%, China’s healthy people with bacterial rate of 10.5%, so that the Uu is a conditional pathogen, check out is not the same as the pathogenicity of the Mh in the NGU does not have an important role in the pathogenicity of Mg may be the causative agent of the NGU. Detection of mycoplasma must be combined with a WBC count in the secretion to determine whether it is bacterial or pathogenic. Correct diagnosis: Therefore, a diagnosis of nongonococcal urethritis (cervicitis) can be made in men with a WBC count of >15/high magnification or ≥5/oil microscope in urethral secretions and in women with a WBC count of >30/high magnification or ≥10/oil microscope in cervical secretions, and gonococcal infection can be excluded. Mycoplasma positive but normal WBC cannot be diagnosed as non-gonococcal urethritis (cervicitis). Myth 2: Mycoplasma remains positive after treatment for nongonococcal urethritis (cervicitis) and treatment is repeated. Correct judgment: because mycoplasma can be a condition of pathogenic bacteria for a long time, so non-gonococcal urethritis (cervicitis) after treatment results of the determination of the experimental examination can be made only for the genitourinary tract specimen WBC count, do not make mycoplasma examination, mycoplasma examination is positive, but the WBC count in the normal range of the treatment can be no longer. Myth 3: Non-gonococcal urethritis (cervicitis) requires long-term high-dose antibiotic treatment. Correct: Long-term high-dose antibiotic treatment for untreated nongonococcal urethritis (cervicitis) is not effective in treating patients. Long-term treatment may be associated with drug-resistant CT or mycoplasma infections, 2 weeks of treatment is ineffective, can be changed to other drugs (can be used in combination with two drugs), prolonged treatment does not improve the efficacy of treatment. In addition, other pathogens should also be considered as possible infections, if necessary, further examination. Myth 4: Patients with nongonococcal urethritis (cervicitis) continue to be treated because they still have symptoms after cure. Correct judgment: patients with non-gonococcal urethritis (cervicitis) can be cured after standardized treatment with normal WBC counts in genitourinary tract specimens, and there is no need for antimicrobial treatment. Some patients have mild redness of the urethral opening or itching in the urethra, which may be caused by the irritation of the urethra caused by the drug discharged from the urethra, if there is no indication of urethritis, the symptoms of this kind of patients can disappear in 3 months after stopping the drug. Some patients have a variety of symptoms, such as abdominal cramps, scrotal sagging sensation, headache and dizziness can be psychological counseling treatment.
