""" long_md = """## Definition Vulvitis refers to external genital pruritus, burning, redness, or rash. Vaginitis denotes inflammation of the vagina, manifesting as discharge (with or without odor) and/or bleeding. When both occur together, the term vulvovaginitis is used, though in practice this term is often applied loosely to patients with dysuria, vulvar pain or itching, or vaginal discharge even when they lack overt signs of inflammation or have only vulvar or only vaginal involvement. ## Epidemiology Vulvovaginitis is a common gynecologic complaint in prepubescent girls. Approximately 75% of cases in this age group are nonspecific, with vaginal cultures showing normal or nonspecific flora in 33-85% of such cases. More specific bacterial causes, such as group A beta-hemolytic streptococcus, account for roughly 10-20% of cases and appear to have seasonal variation. Importantly, among symptomatic premenarchal girls who have visible vaginal discharge on examination (as opposed to irritation and erythema alone), up to 50% have a specific vaginal infection warranting antimicrobial treatment - a distinction that matters for triaging further work-up. ## Etiology Prepubertal girls are predisposed to vulvovaginitis by several age-appropriate anatomic and physiologic factors: the labia do not fully cover or protect the vaginal vestibule from friction and external irritants, particularly when sitting or squatting; the unestrogenized (hypoestrogenized) vaginal epithelium is thin, friable, and easily traumatized; and the vaginal environment is alkaline rather than the protective acidic pH that develops with pubertal lactobacilli colonization. Noninfectious causes include chemical irritants (bath soaps, bubble bath, bath bombs, laundry detergents, swimming pools, hot tubs), poor or inconsistent hygiene, frictional irritation, poor aeration (exacerbated by obesity), tight clothing, and underlying dermatologic disorders. Infectious causes are subclassified into nonsexually transmitted and sexually transmitted pathogens. Nonsexually transmitted bacterial pathogens and herpes simplex virus are often transferred to the vulvovaginal area from another body site (nose, mouth, throat, skin, or GI tract) via the child's own hands (orodigital or autoinoculation transmission). Group A beta-hemolytic streptococcus is a well-recognized cause, sometimes producing serosanguineous discharge; other respiratory flora, including Streptococcus pneumoniae, can also cause purulent discharge with vulvitis and vaginitis, concurrent with or following an upper respiratory infection. Shigella species are another recognized nonsexually transmitted cause, particularly relevant with a history of diarrhea, and can also produce blood-tinged discharge. Candida is a common cause of diaper dermatitis but rarely causes true vulvovaginitis in a prepubertal child who is no longer in diapers, unless a predisposing factor is present, such as diabetes mellitus or systemic antibiotic or steroid use; Candida vulvovaginitis is, by contrast, common after puberty, with more than 80% of cases caused by Candida albicans, and predisposing factors in this age group include pregnancy, oral contraceptive use, and oral antibiotics. Sexually transmitted pathogens causing vulvovaginitis in a prepubertal child are almost always associated with sexual abuse and should prompt that evaluation; Trichomonas vaginalis is more relevant after puberty begins, or in infants via maternal passage during birth. ## Clinical Features Symptoms across most causes of vulvovaginitis are similar: perineal itching or pain, external or contact dysuria, and occasionally vaginal discharge, which can range from clear to white to green or yellow, and may be odorless or foul-smelling. In noninfectious vulvovaginitis, physical findings are often unimpressive despite significant patient and parental concern, and vaginal discharge is unusual. Candida vulvovaginitis typically shows diffuse vulvar erythema, sometimes with white or pink cobblestoned plaques on an erythematous base in chronic cases, excoriations from scratching, satellite lesions on the perineum, perianal dermatitis, and a thick creamy or cheesy discharge; in adolescents, whitish plaques may adhere to the vagina or cervix. After puberty, a normal, asymptomatic increase in vaginal discharge occurs, which may be clear, opaque, white, or yellow, becoming more mucoid mid-cycle after ovulation, and may have an odor but typically no accompanying discomfort - this must be distinguished from pathologic vaginitis. Vulvovaginitis is a relatively uncommon cause of pediatric vaginal bleeding but should be considered, particularly with causes like Streptococcus or Shigella that can produce serosanguineous discharge. Pelvic inflammatory disease primarily affects sexually active adolescents but should raise suspicion of sexual abuse when seen in a prepubertal girl, presenting with abdominal pain. ## Diagnostics A thorough history should cover hygiene practices (front-to-back wiping), possible exposure to chemical irritants, recent diarrhea, perianal or nighttime itching, and the possibility of a vaginal foreign body (though a young child is unlikely to recall or report this). Children with vulvovaginitis symptoms often have had prior evaluations and treatment failures, making a systematic approach important. Cultures with sensitivities for specific pathogens can be obtained using a cotton swab or a urethral (Calgiswab) swab moistened with nonbacteriostatic saline; swabbing can cause discomfort or, rarely, minimal bleeding. Candida infection is confirmed by KOH preparation or wet mount, which shows yeast and often increased inflammatory cells. The diagnosis of nonspecific vaginitis should be made only after other identifiable causes have been excluded through examination and, where indicated, testing. ## Differential Diagnosis Causes are best classified into noninfectious and infectious categories, with infectious further divided into nonsexually and sexually transmitted pathogens. A finding of visible discharge on exam (versus irritation/erythema alone) should raise the pretest probability of a specific infectious cause requiring different management than nonspecific vulvovaginitis. Sexually transmitted infection or pelvic inflammatory disease in a prepubertal child should always prompt evaluation for sexual abuse. ## Treatment Nonspecific vulvovaginitis is managed with hygiene measures: front-to-back wiping, use of wet wipes after bowel movements, proper genital cleansing during baths, routine handwashing, and avoidance of topical irritants, chemicals, and perfumed or deodorant soaps. Candida vulvovaginitis is treated effectively with vaginal creams or troches of nystatin, clotrimazole, or miconazole, or with a single oral dose of fluconazole. Bacterial causes identified by culture (such as group A streptococcus) are treated with targeted antimicrobial therapy. """ clinical_md = """## Evaluating a Prepubertal Girl with Vulvovaginal Symptoms Take a detailed history covering hygiene technique (front-to-back wiping), exposure to chemical irritants (bubble baths, soaps, detergents, pools/hot tubs), tight clothing, recent diarrhea, and perianal or nighttime itching, and gently ask about the possibility of a foreign body, recognizing a young child may not recall or disclose this. On exam, distinguish visible discharge from irritation/erythema alone - visible discharge raises the likelihood of a specific infectious cause to about 50%, whereas irritation without discharge more often reflects nonspecific vulvovaginitis from the combination of unestrogenized mucosa, absent labial protection, and alkaline pH that predisposes all prepubertal girls. Obtain a culture with sensitivities using a moistened cotton or urethral (Calgiswab) swab when a specific infectious cause is suspected, particularly with blood-tinged/serosanguineous discharge (raising concern for group A streptococcus or Shigella) or a history of recent respiratory illness or diarrhea. Reserve a diagnosis of nonspecific vaginitis for after other identifiable causes have been reasonably excluded, since many of these children have already had prior evaluations and treatment failures. ## Recognizing Red Flags and Treating by Cause Treat any prepubertal child with a sexually transmitted pathogen identified on vulvovaginal culture, or with pelvic inflammatory disease, as a sexual abuse concern requiring a full evaluation - this association is close to universal at this age. Consider Candida vulvovaginitis only when a predisposing factor is present (diabetes, recent systemic antibiotics or steroids) in a prepubertal, diaper-free child, since Candida is otherwise an uncommon cause at this age despite being a frequent culprit in diaper dermatitis and in postpubertal vulvovaginitis; confirm with KOH prep/wet mount and treat with topical azole antifungals or, in adolescents, a single dose of oral fluconazole. For nonspecific vulvovaginitis, the majority of cases, focus first-line management entirely on hygiene counseling (front-to-back wiping, wet wipes, gentle genital cleansing, avoiding perfumed soaps and other irritants) before escalating to antimicrobial therapy, since most children improve with these measures alone.
