Infectious Conditions of the Cervix Condyloma Gonococcal Cervicitis Chlamydial cervicitis
Chlamydial Cervicitis In the United States, chlamydial genital infection is the most frequently reported infectious disease, and the prevalence is highest in persons aged ≤25 years MICROBIOLOGY: • Etiologic agent: Chlamydia Trachomatis • Obligatory intracellular bacteria • Infect COLUMNAR EPITHELIAL CELLS • Survive by replication that results in the death of the cell
Chlamydial Cervicitis CLINICAL MANIFESTATIONS: • Majority (70%-80%) are asymptomatic • Local signs of infection, when present, include: • Mucopurulent endocervical discharge • Edematous cervical ectopy with erythema and friability
Chlamydial Cervicitis DIAGNOSIS • Culture- gold standard • Non-culture tests • Nucleic Acid Amplification Tests (NAATs)-most sensitive • Non-Nucleic Acid Amplification Tests (Non-NAATs) • Serology- Rarely used for uncomplicated infections MANAGEMENT • Antibiotic treatment of patient and partner (within past 60 days)
Treatment Recommended RegimensAzithromycin 1 g orally in a single doseORDoxycycline 100 mg orally twice a day for 7 days A recent meta-analysis of 12 randomized clinical trials of azithromycin versus doxycycline for the treatment of genital chlamydial infection demonstrated that the treatments were equally efficacious, with microbial cure rates of 97% and 98%, respectively Sexual abstinence for 7 days 35

ESTABLISHED CO-FACTORS High Parity :Parity of 7 or more increases the risk for cervical cancer. Women who reported 7 or more full-term pregnancies and were HPV positive had a 4-fold increase in risk of cervical cancer compared with nulliparous HPV-positive women with similar characteristics (OR, 3.8; 95% CI, 2.7---5.5). Highparity increase the risk of cervical cancer because it maintainsthe transformation zone on the exocervix for many years facilitating the direct exposure to HPV and, possibly, to othercofactors.

ESTABLISHED CO-FACTORS Oral Contraceptive use Long-term use of oral contraceptives could increase the risk of cervical cancer by up to fourfold in women with HPV infection. An analysis of pooled data from ten case-control studies of patients with invasive cervical cancer or CIS showed that among current users of oral contraceptives the risk of invasive cervical cancer increased with increasing duration of use (relative risk for 5 or more years' use versus never use, 1.90 [95% CI 1.69-2.13]). Hormone-related mechanismsmay influence the progression from premalignant to malignantcervical lesions by promoting integration of HPV DNA into thehost genome, specifically estradiol Level II-2 Grade A International Collaboration of Epidemiological Studies of Cervical Cancer.

ESTABLISHED CO-FACTORS Smoking The risk of squamous cell carcinoma increases in current smokers with the number of cigarettes smoked per day and with younger age at starting smoking. Current smokers had a significantly increased risk of squamous cell carcinoma of the cervix compared to never smokers (RR = 1.60 (95% CI: 1.48-1.73), p<0.001). Malignant transformation of HPV16-immortalized human endocervicalcells by cigarette smoke condensate has been proven . nicotine and tobacco-specific carcinogens have beendetected in the cervical mucus of smokers International Collaboration of Epidemiological Studies of CervicalCancer.

ESTABLISHED CO-FACTORS Early coitus Early age at first intercourse increases the risk for cervical cancer (age 14 and below) The relative risk for age at first intercourse < or =14 versus > or =25 years, conditioned on age, study, and lifetime number of sexual partners was 3.52 (95% CI, 3.04-4.08), which decreased to 2.05 (95% CI, 1.54-2.73) after additional conditioning on reproductive factors.

As the cancer progresses, these signs and symptoms may appear: Early cervical cancer generally produces NO signs or symptoms. • Abnormal vaginal bleeding, usually postcoital • Vaginal discomfort, malodorous discharge, and dysuria • The triad of leg edema, pain, and hydronephrosis suggests pelvic wall involvement
How do we diagnose cervical cancer ? • Pelvic exam- mass is PALPABLE • Punch biopsy is done
