Vulvovaginitis

Vulvovaginitis (also vulvovaginal infections) are inflammatory disorders of the vulva and vagina. They include the following clinical entities:


 * Bacterial vaginosis
 * Trichomonad vaginosis
 * Aerobic vaginosis
 * Vulvovaginal candidiasis
 * Herpetic vulvovaginitis
 * Vaginal lactobacillosis

Etiology
The diverse etiology of infectious origin includes bacteria, viruses, fungi and parasites. Often, the resulting vaginal fluorine transfers to the external genitalia and secondarily infects it by irritation.

Clinical pattern
They are usually characterized by vaginal pruritus or burning, and/or discharge of various nature and/or vulvodynia, depending on the etiology. Signs of inflammation edema, erythema of the vagina or vulva, itching, burning, dyspareunia may be present. It is necessary to focus on the possible ascending progression of the infection, which may cause up to pelvic inflammatory disease (PID) with possible negative consequences (e.g. infertility, ectopic pregnancy or chronic pelvic pain).

Differential diagnosis
To establish the correct diagnosis, it is necessary to assess the clinical picture of the problem (presence and quality of discharge, itching, signs of inflammation, etc.) along with the determination of pH and microscopic examination of the vaginal environment. The microscopic examination is performed either directly in the gynaecological outpatient clinic - native microscopy, or in microbiology, where a Gram-stained slide is most often read (assessed, for example, according to Nugent). The microscopic native examination is supplemented by a sniff test for volatile amines with one drop of 10% KOH solution (see bacterial vaginosis) and microscopic examination of this preparation (KOH dissolves practically everything except yeast).

The previously recommended microbial vaginal pattern (mikrobiální obraz poševní - MOP) has insufficient clinical relevance. E.g. also because of significant differences in the vaginal microbiome according to ethnicity (MOP is standardized to the Caucasian population). Also, culture examination is only a complementary examination.

In patients with suspected chlamydial cervicitis (recurrent watery discharge, absence of signs of vaginal inflammation, postcoital spotting, etc.) we take a cervical canal swab for the presence of chlamydia (PCR, immunofluorescence, etc.).

The examination algorithm can also be supplemented by cytological examination of the cervix.

Therapy
It is always determined by the etiology. In a severe course, conventional treatment can be combined with corticosteroids. Conversely, for isolated vulvodynia, topical administration of corticosteroids is often sufficient.
