Serum estradiol levels in infants with and without labial adhesions: the role of estrogen in the etiology and treatment

17β-estradiol Attenuates the Middle Ear Inflammatory Response to Nontypeable Haemophilus influenzae

OBJECTIVES

17β-estradiol (E2) is a steroidal hormone with immunomodulatory functions that play a role in infectious and inflammatory diseases. E2 was recently identified as the leading upstream regulator of differentially expressed genes in a comparative RNA sequencing study of pediatric patients with otitis media (OM) versus OM-free counterparts and may therefore play a role in the inflammatory response to bacterial otopathogens during pediatric OM. This study examined the effect of E2 on bacterial-induced inflammatory cytokine expression in an in vitro pediatric OM model.

METHODS

An immortalized middle ear (ME) epithelial cell line, ROM-SV40, was developed from a pediatric recurrent OM patient. The culture was exposed to E2 at physiological levels for 1-48 h prior to 6 h-stimulation with nontypeable Haemophilus influenzae (NTHi) whole cell lysate. TNFA, IL1B, IL6, and IL8 were assayed by qPCR and ELISA.

RESULTS

E2 pretreatment (24 h) abrogated NTHi induction of IL6; a longer pretreatment (1-10 nM, 48 h) abrogated IL1B induction (p < 0.05). E2 pretreatment (5 nM, 48 h) abrogated NTHi-induced IL8 secretion (p = 0.017).

CONCLUSION

E2 pretreatment partially rescued NTHi-induced cytokine production by ME epithelia. These data support a role for E2 in moderating the excessive inflammatory response to middle ear infection that contributes to OM pathophysiology.

Treatment of Prepubertal Labial Adhesions with Topical Estriol + Testosterone: A Case Report

BACKGROUND

Labial adhesions, a frequent gynecological condition in prepubertal girls, occur when the labia minora adhere along the midline. The prevailing hypothesis about their etiology suggests that labial adhesion may occur when the delicate and non-estrogenized labia minora undergo an inflammatory response, triggered by exposure to an irritant environment. Therefore, conservative treatment involves the application of topical estrogen or betamethasone cream. The role of androgens has not been considered yet in the pathophysiology or therapy of this condition. However, some studies have shown that androgen receptors are prevalent in the labia minora and vulvar vestibule.

CASE SUMMARY

We present the case of a 29-month-old girl with symptomatic labial adhesions. She was first ineffectively treated with topical estriol, and then she was treated with a galenic cream containing both estriol and testosterone with complete recovery and without side-effects.

CONCLUSIONS

Both androgens and estrogens play a significant role in maintaining the physiological trophic state of the vulva and vagina, even during childhood. Topical estriol+testosterone could be considered an alternative treatment for prepubertal labial adhesions refractory to standard topical therapy.

Manual separation of labial synechiae: A cost-effective method in prepubertal girls

BACKGROUND

Labial synechiae is a fairly common gynaecological problem that occurs as a result of inflammation leading to fusion between the labia minora. Being in a developing country with limited resources and poor compliance of patients to prolonged treatments, we are faced with immense challenges in the management of these girls.

AIMS

We wanted to evaluate the efficacy and the cost-effectiveness of manual separation and topical antibiotics with perineal hygiene in the management of pre-pubertal girls with labial synechiae.

MATERIALS AND METHODS

Design.

Prospective, non-randomised interventional study. Participant: Pre-pubertal girls presenting with the diagnosis of labial synechiae in the period from September 2015 to January 2018. Interventions: Manual separation followed by topical antibiotic ointment application for 1 week with local hygiene. Outcomes measure: Complete release of the synechiae and no recurrence up to 6 months.

RESULTS

Out of the total 55 patients, only 48 patients were included, their age ranged from 3 months to 7 years (mean 2.8 years). Almost half of our patients were asymptomatic, and other half had symptoms (urinary tract infection, dripping of urine and itching). Majority of our patients belong to low middle class status. We had 100% complete release of synechiae and no recurrence on 6 months follow-up.

CONCLUSION

Manual separation followed by topical antibiotics is a cost-effective method of the treatment of labial synechiae with immediate response and low recurrence rate.

Persistent Labial Minora Fusion in Reproductive Age Women: A Retrospective Case Series of Nine Patients and Review of Literature

Labial minora fusion persisting to the reproductive age is a rare type of labial fusion. Only 17 sporadic case-reports have been published to describe this disease. We report a retrospective cohort study of nine patients undergone surgical dissections in our hospital with labial minora fusion of reproductive age. General information, a medical history, gynecological examinations, preoperative ultrasonography and observations during surgery were reviewed. Four patients found vulva deformity at age 1.25 ± 1.09 years, and the remaining 5 patients discovered the disease when they reached child-bearing age (25.20 ± 4.31). The average age of operation was 22.89 ± 6.21 years. The characteristic symptoms of the disease were menstrual blood and urine excretion from the urethral orifice. No endometriosis was detected in all 9 patients. One patient was found to have congenital defects, with a double cervical and complete uterine septum. All patients recovered well without re-adhesion. Seven patients (7/9, 77.80%) were interviewed by telephone. Three patients had normal sexual life and all patients were able to control urination normally. This labial fusion was found in 44.44% patients shortly after birth and might combined with other defects, suggesting a congenital nature of the disease, and further indicates the developmental feature of the vulva.

Labial Adhesion: New Classification and Treatment Protocol

STUDY OBJECTIVE

To determine the subtypes of labial adhesion (LA) and arrange treatment options accordingly.

DESIGN AND SETTING

Patients who presented to our clinic with LA between July 2016 and February 2018 were divided into 4 groups. Location of the adhesion area, thickness of the adhesive tissue, and response to topical steroid (betamethasone valerate 0.1% ointment) therapy were identified as common features.

PARTICIPANTS

Seventy-five prepubertal girls.

INTERVENTIONS AND MAIN OUTCOME MEASURES

To determine the subtypes of the LA and evaluate the treatment response of patients in each subtype group.

RESULTS

LA was divided into 4 subtypes according to their common characteristics. For patients with type I, 2 weeks of topical steroid treatment resulted in complete recovery (100%). For those with type II, 12 (80%) patients had complete response to topical steroid treatment for an average of 3 weeks. Type III and IV patients were completely unresponsive to topical steroid treatment.

CONCLUSION

Classification of LA patients into subtypes and determination of treatment on the basis of this classification make a major contribution in planning the treatment of patients, not by trial-and-error, but using a predetermined strategy.

Treatment of Prepubertal Labial Adhesions: A Randomized Controlled Trial

STUDY OBJECTIVE

Although various treatment options have been proposed for the treatment of labial adhesions, there are currently no clearly outlined limits on the duration of topical therapy, amount of lateral traction to apply, and methods to decrease the recurrence. This clinical trial was undertaken to assess the need for estrogen for treatment of prepubertal labial adhesions.

DESIGN

Randomized, double-blinded, controlled trial.

SETTING

Pediatric and Adolescent Gynecology Clinic at a children's hospital in a metropolitan area.

PARTICIPANTS

Prepubertal girls ages 3 months to 12 years with labial adhesions.

INTERVENTIONS

Lateral traction with topical estrogen or topical emollient.

MAIN OUTCOME MEASURES

The primary outcome was resolution of labial adhesions. The secondary outcome was the change in severity of labial adhesions over time between the 2 groups.

RESULTS

Forty-three girls were enrolled and 38 (88%) completed the study. The difference in complete resolution between the topical emollient group (19%) and the topical estrogen group (36%) was not statistically significant (P = .21). There was a statistically significant decrease in severity of labial adhesions over time, with the magnitude of improvement favoring the topical estrogen group.

CONCLUSION

Although labial adhesion severity decreased when treated with lateral traction and topical emollient or topical estrogen, the magnitude of the effect was significantly greater for topical estrogen.

Developmental and family history-based analysis of congenital fused labia phenotype in the captive common marmoset (Callithrix jacchus)

BACKGROUND

Congenital fused labia (CFL) is defined as a failure or significant delay in the opening of the juvenile sealed labia majora. This phenotype is known to be variably common in adult captive female marmosets but has never been investigated in detail before.

MATERIALS AND METHODS

Here, we define, describe and quantify the variations in the degree of closure of the vulva in 122 captive marmosets (Callithrix jacchus) from 1.2 to 42 months old and include colony analysis.

RESULTS

There was a negative correlation between the degree of labial fusion and animal age after prepubertal period (P < 0.05). CFL females had higher number CFL relatives (4.3 ± 0.6 vs 2.4 ± 0.5 for non-CFL, P < 0.05) and more external ancestors compared to non-CFL (P < 0.05).

CONCLUSIONS

Our results therefore suggest that CFL phenotype is most likely associated with epigenetic effects induced by the captive environment and colony management strategy of extensive crossing of family lines to promote heterozygosity.

Acquired Labial Adhesion in a Reproductive-Aged woman secondary to Systemic Lupus Erythematosus

Labial adhesion is a rare condition in reproductive-aged women. There are only a few reported cases of labial adhesion in this period of woman’s life. We herein, present a case of a 22-year-old G1P1 woman with a thick and fibrous labial adhesion. The labial adhesion was excised, and the labial mucosa was sutured under local anaesthesia. Her hormonal profile (FSH, LH and estrogen levels) was found to be normal. The patient was later diagnosed with systemic lupus erythematosus (SLE) by a rheumatologist. It is the first case report that shows a relationship between SLE and labial adhesion.

Comparison of Conservative and Surgical Therapy Concepts for Synechia of the Labia in Pre-Pubertal Girls

Introduction: The aim of this study was to evaluate the primary and secondary therapeutic successes of different therapy schemes for the treatment of synechia of the labia in pre-pubertal girls. Materials and Methods: The treatment courses of 47 pre-pubertal girls who were treated between February 2007 and February 2013 in the special outpatient clinic for paediatric gynaecology of a department for gynaecology at a German university hospital and for whom information on the course of the disease was available for at least the six months following end of the treatment. 23 of these children were treated with a topical estriol therapy (treatment group A). For 24 of the girls a manual separation of the adhering labia minora was undertaken (treatment group B). Statistical evaluation was performed using the χ² test, Fischer's exact test and the Mann-Whitney U test. Results: For 18 of the 23 (80 %) girls in treatment group A topical estriol therapy alone led to a resolution of the synechia. Five of these 23 children (20 %) required a secondary manual separation. All girls for whom treatment was not successful were under 5 years of age. For all 24 girls (100 %) of treatment group B the primary manual separation was performed with success. The recurrence rates after ≥ 6 months in cases with identical after-care did not differ between the two treatment groups (treatment group A: 34 %, treatment group B: 33 %, χ² test: p = 0.853). 16 of the 17 recurrences occurred ≥ 3 months after the end of the therapy. Conclusion: Our results show that for children < 5 years of age a 4-week topical therapy with estriol is a promising therapy option for synechia of the labia that is less of a burden for the family situation. Especially for girls ≥ 5 years of age, primary therapy fails in up to 20 % of the cases. Primary manual separation represents a more effective therapeutic option. Irrespective of the treatment applied, a recurrence after ≥ 3 must be expected in one-third of the treated girls.

Labial adhesions and outcomes of office management

STUDY OBJECTIVE

To evaluate clinical outcomes of labial adhesions (LA) and to examine the association between LA, lichen sclerosus (LS), eczema (ECZ), or asthma.

DESIGN

Retrospective study.

SETTING

Single pediatric and adolescent gynecology clinic, Houston, Texas.

PARTICIPANTS

50 girls diagnosed with LA from 2006-2011.

INTERVENTIONS AND MAIN OUTCOME MEASURES

Resolution, recurrence, single vs multiple treatments, need for surgery, and conditions such as LS, ECZ, and asthma were reviewed.

RESULTS

Mean age was 19.6 months (range 0-84 months), and 48% were Caucasian. Most patients were symptomatic (62%) and all 50 patients chose estrogen treatment. The majority (74%) required multiple treatments, as opposed to a single treatment (26%). Patients with multiple treatments were more likely to be severely agglutinated (P = .05) and to need manual separation after failed topical treatment (P = .08). The prevalence of asthma, LS, and ECZ was 9.8%, 7.8%, and 3.9% respectively. There was no association between LS, ECZ, or asthma, and number of treatments. Both asthma (N = 3; 8%), and LS (N = 2; 5%) were present among the severe agglutinated group; however, this difference was not statistically significant (P values .59 and .99). No association with ECZ was seen in either group.

CONCLUSION

Severe agglutination tends to be associated with need of multiple treatments and manual separation. A concurrent diagnosis of LS, ECZ, or asthma was not associated with number of treatments but there appears to be a trend towards severity of LA in patients with asthma and LS.

How should we treat prepubertal labial adhesions? Retrospective comparison of topical treatments: estrogen only, betamethasone only, and combination estrogen and betamethasone

Labial adhesion is a common finding in prepubertal girls. Traditionally, topical estrogen cream application has been the choice of conservative treatment, however, topical betamethasone treatment has also recently been employed with some success. In this retrospective study, we analysed 131 children with labial adhesions. Eleven of 71 (15.4%) patients were treated successfully with topical estrogen cream only, and 5 of 32 (15.6%) patients were treated successfully with betamethasone cream only. We successfully treated 5 of 28 (28.5%) patients with a combination of estrogen and betamethasone creams. The mean time of treatment for each regimen of therapy was 4 weeks. There was no significance between the single-therapy estrogen and single-therapy betamethasone groups (P = 1.00), between single-therapy estrogen and the combination therapy (P = .16), and the single therapy betamethasone to combination therapy (P = .35) groups. There was also no significant difference between combination estrogen and betamethasone therapy and the combined data of the single therapies (relative risk 1.85; 95% confidence interval 0.89-3.89; P =.11). For the treatment of prepubertal labial adhesions, topical estrogen and betamethasone creams were found to have similar success rates, with limited satisfactory results. The combination therapy was mildly more efficacious than each of the single therapies but was not found to be statistically significant. Surgical separation is recommended if conservative treatment fails.

Detection of RXFP1 receptors in skin biopsies from children with congenital adrenal hyperplasia: a preliminary report

OBJECTIVE

Relaxin may potentiate the effect of topical estrogen treatment to eradicate post-incisional scarring in congenital adrenal hyperplasia (CAH) patients undergoing genitoplasty. The aim of this study was to determine whether CAH skin is capable of responding to relaxin.

PATIENTS AND METHODS

Skin biopsies were obtained from four female CAH patients (aged 2-9 years; Prader 4-5, salt-wasting, 21-hydroxylase deficiency, Caucasian) during routine genitoplasty surgery and screened for relaxin receptors. All received corticosteroid and mineralocorticoid replacement therapy. Specimens were sectioned, mounted and screened for the presence of the putative H2 relaxin receptor using conventional two-antibody immunohistochemistry. Tissue controls were processed concurrently.

RESULTS

Tissue controls evidenced appropriate staining. Biopsies from CAH patients stained positively for RXFP1 expression while some variation between specimens was evident. Staining occurred adjacent to the basement membrane of the epithelium, localized to germinative basal keratinocytes.

CONCLUSION

Based on a limited patient sample, germinative keratinocytes in CAH patients appear competent to respond to relaxin perhaps topically applied. Given that relaxin downregulates collagen accretion and upregulates collagenases, its use may potentiate the effects of estradiol and abrogate post-incisional wound scarring. More research is needed to confirm or refute this thesis.

Success of treatment modalities for labial fusion: a retrospective evaluation of topical and surgical treatments

STUDY OBJECTIVE

Standard treatment for girls with labial fusion has included topical estrogen cream, manual separation, or surgery. Side effects may limit the use of topical estrogen. Betamethasone has recently shown efficacy at separating labial fusion. Local irritation and inflammation may be an initiator of labial fusion. No adverse effects of betamethasone treatment have been documented. Long-term side effects are unknown. This study compares therapies for conservative management of labial fusion for efficacy and focuses on the response rate, time to separation, recurrence, and side effects of treatment.

DESIGN

A retrospective chart review.

PARTICIPANTS

One hundred fifty-one prepubertal girls, mean age 3 years (range 0.25-8.75 years) diagnosed with labial fusion.

MAIN OUTCOME MEASURES

To investigate the incidence of related symptoms, length of topical estrogen or betamethasone treatment, side effects, rate of successful separation, rates of recurrence, percentage requiring surgery, and postoperative outcomes in patients with labial adhesion who underwent treatment.

RESULTS

Of 151 patients with labial adhesion, 11 (7.3%) presented with urinary frequency, 30 (19.9%) with urinary tract infections, 13 (8.6%) with vaginitis, and 19 (12.6%) with post-void dripping. When compared to patients treated with betamethasone (1.3 months), patients treated primarily with premarin took nearly twice as long (2.2 months) for resolution of their adhesions. Rates of recurrence were lower for patients receiving betamethasone therapy. Side effects for estrogen therapy included breast budding and vaginal bleeding, and for betamethasone, local irritation was reported. Some patients went on to surgery and experienced recurrence after surgery.

CONCLUSION

Initial comparison of topical estrogen and betamethasone treatment of labial fusion suggests that betamethasone may separate fusion quicker with less recurrence and fewer side effects than topical estrogen therapy.
