| | = Chlamydia = |
| Chlamydia is most common STD, if you don’t count <abbr>HPV</abbr>. It’s caused by Chlamydia trachomatis serotypes D-K. It may progress to pelvic inflammatory disease. | | {{#lst:Chlamydia|gynaecology}} |

|
| === Clinical features === | | = Trichomoniasis = |
| 90% of affected people are asymptomatic. Possible symptoms include:
| | {{#lst:Trichomoniasis|gynaecology}} |
| | |
| * Urethritis with dysuria
| |
| * Mucopurulent discharge
| |
| * Postcoital bleeding
| |
| | |
| === Diagnosis and evaluation ===
| |
| PCR of vaginal swab.
| |
| | |
| === Treatment ===
| |
| Single dose 1 g PO azithromycin or doxycyclin for 7 days.
| |
| | |
| === Complications ===
| |
| Reiter syndrome/reactive arthritis is a complication of many bacterial infections, most commonly after chlamydia. It’s associated with HLA-B27 and mostly affects young males. It’s characterised by a clinical triad of:
| |
| | |
| * Arthritis
| |
| * Conjunctivitis
| |
| * Urethritis
| |
| | |
| == Trichomoniasis ==
| |
| Trichomoniasis is a sexually transmitted infection caused by trichomonas vaginalis. | |
| | |
| === Clinical features ===
| |
| It’s asymptomatic in 70%. Foul-smelling, yellow-green coloured vaginal discharge is highly suspicious for trichomoniasis. Other symptoms include:
| |
| | |
| * Itching
| |
| * Burning
| |
| * Dyspareunia
| |
| * Itchiness
| |
| * Redness
| |
| * Strawberry cervix – typical appearance of cervix like a strawberry
| |
| | |
| === Diagnosis and evaluation ===
| |
| Physical examination may reveal characteristic appearance or odour.
| |
| | |
| pH measurement is also important. The pH of the vagina is normally 4 – 4,5, but in case of bacterial vaginosis or trichomoniasis, the pH is > 4,5. The Amine test (for bacterial vaginosis) is positive here as well.
| |
| | |
| Vaginal smear, the examination of vaginal fluid under the microscope, may also be performed. For trichomoniasis, motile organisms with multiple flagella are visible.
| |
| | |
| === Treatment ===
| |
| Metronidazole is the first line treatment for both the patient and the partner.
