Voiding dysfunction: another etiology of vulvovaginitis in young girls

Microbiological Findings of Symptomatic Vulvovaginitis in Chinese Prepubertal Girls

STUDY OBJECTIVE

To study the bacteria and fungi causing vulvovaginitis in prepubertal girls.

DESIGN

Swabs from vaginal introitus were collected from patients with vulvovaginitis in 2018, and cultured for the identification of microorganisms with standard microbiological techniques.

SETTING

A children's hospital in Hangzhou, East China.

PARTICIPANTS

A total of 1235 Chinese prepubertal girls diagnosed with vulvovaginitis.

MAIN OUTCOME MEASURE

Bacteria or fungi in pure cultures or as the predominant organism were defined as pathogens.

RESULTS

A total of 1235 cases were diagnosed as vulvovaginitis, and 515 isolates were identified from 494 patients (40%, 494/1235). The most common pathogen was Streptococcus pyogenes (27.6%,142/515), followed by Haemophilus influenzae (27.2%,140/515), Candida albicans (22.3%,115/515), Staphylococcus aureus (5.8%, 30/515) and Escherichia coli (4.7%,24/515). All S pyogenes isolates were sensitive to penicillin, whereas 53.7% (73/136) of H influenzae isolates were sensitive to ampicillin, and 70.4% (19/27) of S aureus isolates were sensitive to oxacillin.

CONCLUSION

S pyogenes and H influenzae were the 2 most commonly identified pathogenic bacteria found in prepubertal girls with vulvovaginitis. Vulvovaginitis in prepubertal girls caused by C albicans may be more common in older children.

Prepubertal Vulvovaginitis

Vulvovaginitis is a common gynecologic complaint in prepubertal girls. It typically presents with complaints of vulvovaginal itching, burning, irritation, discharge, or skin changes. Prepubertal females have anatomic, physiological, and behavioral factors that most often contribute to the development of symptoms. Careful attention to history and associated complaints will direct evaluation, diagnosis, and treatment. Most cases are nonspecific in origin and treatment includes counseling to patients and parents on hygiene and voiding techniques. Antibiotic treatment for specific pathogens may be indicated. Other less common causes include foreign bodies and lichen sclerosus.

Clinical presentation, diagnosis and treatment of vulvovaginitis in girls: a current approach and review of the literature

BACKGROUND

Vulvovaginitis is the most common cause of gynecological complaints in children and young girls. Some of the factors which cause vulvovaginitis include hypoestrogenism, the anatomical proximity of rectum and delicate vulvar skin and vaginal mucosa.

DATA SOURCES

We made a literature search with Pubmed, Medline and Cochrane database from January 2002 to May 2015 in English language using the key words vulvovaginitis, children, clinical, diagnosis and treatment.

RESULTS

Vulvovaginitis in girls is usually caused by non-specific factors and hygiene measures, bioyoghurt and avoidance of chemical irritants are generally useful. Weight control if necessary and prevention of voiding dysfunction are effective. Vaginal flora is important in girls and results should be interpreted with clinical features to decide whether an isolated microorganism is part of the normal microflora or is the cause of symptomatic vulvovaginitis. Specific treatment is generally considered in case of a detected pathogen microorganism. Isolation of a sexually transmitted organism requires further investigation. Persistent disease may not always indicate a foreign body but it must be taken into account. Girls and parents are encouraged psychologically in all steps of evaluation, diagnosis and treatment. Probiotics, nanotechnology and petroleum jelly are other important treatment options used in vulvovaginitis.

CONCLUSIONS

In this review, we present current approach to the presentation and management of vulvovaginitis in childhood. This disorder requires a comprehensive evaluation in all steps of diagnosis, differential diagnosis and treatment.

Personal Hygiene and Vulvovaginitis in Prepubertal Children

STUDY OBJECTIVE

To determine and compare clinical and microbiological features of vulvovaginitis in prepubertal girls. Vulvovaginitis is the most common gynecological problem of childhood. DESIGN, SETTING, PARTICIPANTS, INTERVENTIONS, AND MAIN OUTCOME MEASURES: This study involved 45 girls from 2-12 (5.38 ± 2.9) years old; and 26 girls from 3-12 (5.72 ± 3.1) years old as a control group. Anamnesis and physical examination were followed by vaginal smear, urine culture, and stool analyses from both groups, and the personal hygiene status and education level of the mother were determined.

RESULTS

The most common symptoms among the patients were vaginal discharge (44.4%, vulvar erythema (37.8%), and vaginal itch (24.4%). Microorganisms, isolated from vaginal smears, were detected in 48.9% of the patients. Escherichia coli was shown in the urine culture of 3 patients with vulvovaginitis (6.70%). In microscopic stool analysis parasites were detected (45.9%). We found some relevant personal hygiene factors, such as wiping back to front (42.9%), cleaning by herself after defecation (89.3%), using toilet paper (60.7%) and wet wipes (21.4%), and bathing standing (14.3%) and sitting (46.4%) among patients. The questionnaire also showed that the children wore tight clothing (35.7%).

CONCLUSION

Our findings suggest that vulvovaginitis in prepubertal girls is related not only to microorganisms but also poor personal hygiene, the educational status of mothers, and specific irritants.

Phantom urinary incontinence in children with bladder-bowel dysfunction

OBJECTIVE

To report a previously undescribed condition in which children present with the sensation of wetness because of presumed urinary incontinence when they are actually completely dry. We have termed this entity "phantom" urinary incontinence (PUI).

MATERIALS AND METHODS

Twenty children referred to our pediatric urology clinic were diagnosed with PUI between 2009 and 2013. Patient demographics, associated bladder and bowel symptoms, concomitant diagnoses, imaging, management, and treatment outcomes were evaluated.

RESULTS

Twenty children (18 females and 2 males) were diagnosed with PUI over a 5-year interval. Mean age at diagnosis was 6.9 ± 2.5 years (range, 4-12 years). Nineteen patients (95%) had concomitant lower urinary tract symptoms, and all were also diagnosed with constipation. Urgency (75%) and frequency (50%) were the most common associated bladder symptoms. Of the 18 girls, 13 (72%) had associated vaginitis. Fourteen children (70%) carried a parent-reported diagnosis of obsessive-compulsive disorder or obsessive-compulsive disorder personality traits. Patients were managed with timed voiding, dietary modifications, and a bowel regimen. Ninety percent children experienced improvement of bladder-bowel dysfunction and resolution of PUI at a mean follow-up of 14.4 months.

CONCLUSION

Children with PUI have a high incidence of obsessive-compulsive traits. Phantom incontinence as well as associated lower urinary tract symptoms resolve with adherence to a strict bladder-bowel regimen.
