Cotton fiber ball as an unusual cause of vaginal discharge in a 5-year-old child

Vaginal discharge in children can be due to many causes. Foreign body in vagina is an unusual cause. Foul-smelling, blood-stained vaginal discharge should raise the suspicion of foreign body in vagina. Magnetic resonance imaging (MRI), vaginal examination under general anesthesia may detect foreign bodies in vagina. We found a cotton fiber ball in vagina, probably caused by the child's teddy bear as a cause of vaginal discharge in a 5-year-old child. A repeat MRI suggested foreign body in the vagina and vaginal exploration under general anesthesia helped for the removal of cotton fiber ball, which led to complete clearance of the vaginal discharge in the child.

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.

Care of the Adolescent After an Acute Sexual Assault

Sexual violence is a broad term that encompasses a wide range of sexual victimizations. Since the American Academy of Pediatrics published its last policy statement on sexual assault in 2008, additional information and data have emerged about sexual violence affecting adolescents and the treatment and management of the adolescent who has been a victim of sexual assault. This report provides new information to update physicians and focuses on the acute assessment and care of adolescent victims who have experienced a recent sexual assault. Follow-up of the acute assault, as well as prevention of sexual assault, are also discussed.

Prevalence of Trichomonas vaginalis and risk factors in women treated at public health units in Brazil: a transversal study

BACKGROUND

Studies have revealed high prevalence rates of Trichomonas vaginalis in men and women worldwide. In Brazil, where reporting is not mandatory, the true prevalence rate is unknown. This study determined the prevalence of the parasite in women attending public health units in the city of Uberlândia, Minas Gerais, Brazil, identifying possible risk factors for infection, and also compared three diagnostic techniques for detecting the parasite.

METHODS

Samples of vaginal secretions collected from 742 women attending public health units were analyzed by direct wet mount examination, culture and smear test. Epidemiological questionnaires were administered.

RESULTS

Of the total of 742 samples analyzed, 19 (2.6%) tested positive for T. vaginalis. The variables significantly associated with infection were: being of black ethnicity, smoking, having knowledge about sexually transmitted diseases and presenting clinical signs. The culture method was considered the gold standard test.

CONCLUSIONS

Although there are programs to control other sexually transmitted diseases, there are none for trichomoniasis. The results of this study indicate the presence of T. vaginalis in the female population, and points to the need for more research in Brazil to gain a better understanding of the profile and epidemiology of the parasite.

UK National Audit of Sexual History-taking: clinic policies audit

Provision of a confidential, private environment for sexual history-taking was provided in almost all clinics. However, less than half of the clinics had a policy displayed about their confidentiality policy in waiting areas, although more had this available by other means. About two-thirds of clinic information/advertising literature included information about the need to take a sexual history. Sixty percent of clinics assessed clinician communication skills as part of service quality. Most clinics had policies relating to patients whose first language is not English, but only around half of clinics had policies for hearing difficulties and learning difficulties. Policies are also lacking in some clinics for documentation of the offer of chaperones and assessment of the competency of under-16-year-olds to consent to history-taking and examination.

Management of under-16-year olds in UK genitourinary medicine clinics: British Co-operative Clinical Group

Summary:

In 2004, the management of under-16-year olds in UK genitourinary (GU) medicine clinics was surveyed. Questionnaires were sent to 185 lead GU medicine consultants. A total of 111 questionnaires were returned (60%). Ninety-eight percent of respondents managed young people aged 13-16. Fifty percent managed under 13-year-olds. Twenty-nine percent of respondents ran dedicated young people's clinics. Ninety-eight percent were aware of the National Guidelines, and 74%had adopted them. Fifty-seven percent had a named departmental child protection lead. Thirty-seven percent of consultants had received training specific to child protection issues in GU medicine. Improvements had been made since a similar survey published in 2001, but the need for further training was still apparent.

Care of the adolescent sexual assault victim

Sexual assault is a broad-based term that encompasses a wide range of sexual victimizations including rape. Since the American Academy of Pediatrics published its last policy statement on sexual assault in 2001, additional information and data have emerged about sexual assault and rape in adolescents and the treatment and management of the adolescent who has been a victim of sexual assault. This report provides new information to update physicians and focuses on assessment and care of sexual assault victims in the adolescent population.

Child sexual abuse and sexually transmitted infections: review of joint genitourinary medicine and paediatric examination practice

Joint examination by doctors with complementary skills and screening for sexually transmitted infections (STIs) are recommended in children who may have been sexually abused or have been found to have an STI. Our study showed that criminal proceedings were more likely to be brought in cases with physical signs of sexual abuse. It could be difficult to prove whether sexual abuse had taken place or not with microbiological evidence alone, in the absence of other evidence. Significance of viral STIs in the context of sexual abuse should be evaluated carefully. The review of our practice re-enforced the importance of joint examination of children with suspected STIs.

Impact of National Chlamydia Screening Programme on sexual health of children under the age of 16 years

The objectives of the study were to investigate the rates of sexually transmitted infections (STIs), uptake of full STI screening and contraceptive use during pre- and post National Chlamydia Screening Programme (NCSP) periods and to determine the prevalence of sexual abuse/assault. The method used was a retrospective case notes audit of children aged <16 years. STIs were found in 20% (n = 264) of children; 10% had genital chlamydia. 157 (59%) of 264 children had an assessment for non-consensual sexual activity; of those, 34% had a history of past or continuing sexual abuse/assault. An uptake of 'full STI screening' and contraceptive use were similar in both pre- and post-NCSP periods. Overall STIs and chlamydia rates were higher during post-NCSP period. In conclusion, NCSP has not yet made any significant impact on sexual health of under-16-year-olds and the prevalence of past or ongoing sexual abuse/assault was high.

Evidence for sexual transmission of genital herpes in children

INTRODUCTION

Genital herpes in a prepubertal child presents a child protection clinician with a difficult problem: how likely is it that transmission occurred as a consequence of sexual abuse? Published guidelines on the management of sexually transmitted infections in children provide varying recommendations and refer to a limited literature.

OBJECTIVE

To review the evidence for the likelihood of sexual transmission in a child with proven genital herpes.

METHODS

Structured literature search for reports of series of children presenting with genital herpes where an assessment for possible sexual transmission or child sexual abuse had been made.

RESULTS

Five suitable papers were identified. Although just over half of reported cases of genital herpes in children had evidence suggestive of a sexual mode of transmission, the quality of assessment of possible sexual abuse was too weak to enable any reliable estimation of its likelihood. Sexual transmission is reported more commonly in older children (aged > or =5 years), in children presenting with genital lesions alone and where type 2 herpes simplex virus is isolated.

CONCLUSIONS

Child protection clinicians should be aware of the weakness of the evidence on the likelihood of sexual transmission of genital herpes in prepubertal children. The US guidance that child sexual abuse is "suspicious" reflects the evidence better than the UK guidance that it is "probable". A larger, more up-to-date, methodologically sound, population based study is required.

Sexually transmitted infections in preadolescent children

Pediatric nurse practitioners may be called on to conduct an assessment for sexual abuse of a young child. Depending on the type of sexual contact, a decision may have to be made to obtain cultures for sexually transmitted infections (STIs). Recognizing the symptoms of STIs in preadolescent children, along with having knowledge of the modes of transmission, diagnostics, and treatment, are part of the clinical decision. The impact of STI in preadolescent children has physical and emotional consequences for the child and family, along with legal consequences for an accused perpetrator. Knowledge about types of sexual contact that necessitate STI cultures, incubation periods, and symptomatology is essential. Accurate techniques and appropriate selection of culture materials are necessary. Proper positioning of the child for obtaining cultures can decrease the potential for discomfort during the examination. Gonorrhea, Chlamydia trachomatis, herpes simplex virus, human papillomavirus virus, syphilis, Trichomonas vaginalis, hepatitis B, and HIV are reviewed.

Recording what happens in the under-16 consultation

BACKGROUND

Clinical staff offering sexual health services to young people need to balance the rights of the young person to confidentiality and good quality advice with the need to protect their wider interests. The needs of young clients may be complex and raise ethical and medico-legal questions for the staff involved in their care.

METHODS

In our large, integrated sexual health service, a 'recording form' was introduced to prompt staff to record data systematically pertinent to consultations in clients under 16 years of age, to understand what kind of presentations dominate in these consultations, and to establish how common child protection concerns are.

RESULTS

From April to October 2004, more than 500 forms were completed in our service. The age range for female clients was 12-15 years, with the median age of first sexual intercourse 14 years. Most respondents were in consensual relationships with partners of around their own age, but 10% had been in relationships of less than a week's duration. Most had not told their parents of their sexual activity and did not intend to. Child protection issues did occur, although not commonly.

CONCLUSIONS

Most clients initially present requesting emergency contraception or pregnancy testing, and the inference is that unprotected sexual intercourse is common in this group of clients before they seek our services. The data collected give a valuable overview of the type of issues dealt with in the clinical context and can help to target training and teaching, in addition to potentially highlighting child protection issues.

Forensic examination of suspected child victims of sexual abuse in the UK: a personal view

Expert opinion in child abuse has received considerable bad press and currently public confidence in this area of medical practice is low. Media interest has focused most on the diagnosis of factitious illness. However doctors who examine children in respect of proceedings arising from suspected sexual abuse should be mindful this area is potentially just as problematic. Widely different rates of abnormal findings have been reported. At least in part this has reflected inconsistency in interpretation. Findings once assumed diagnostic of penetration are now recognised to occur in non-abused children. The practical difficulties of examining a reluctant child and achieving adequate visualisation of the hymen in relaxed state, are frequently underestimated. Where normal or non-specific findings are presented as "consistent with the alleged event" there is a high risk the court will perceive them to be significant. Guidelines have tended to lag behind existing knowledge and made inadequate differentiation between prepubertal and adolescent cases. They have also placed a high degree of reliance on statements from children without regard to the context in which any "disclosure" had arisen. Photodocumentation has important benefits, and limitations. Images may not display the true depth of field and are not the same as examining the child directly. Examination must remain the gold standard. There is a moral duty of care on the examining doctor to understand and clarify the status of findings dispassionately and with due regard to the level of the evidence base.

Interventions de prévention efficaces contre le VIH et l’hépatite C chez les jeunes utilisateurs de drogues par injection (UDI)

La dernière décennie a été marquée par une augmentation importante du nombre de pays rapportant que l’injection de drogues est présente dans leur population. Et, dans plusieurs pays, particulièrement dans ceux en voie de développement, la plupart des nouveaux injecteurs ont entre 15 et 24 ans. De nombreuses conséquences sociales et sanitaires sont associées à l’injection de drogues, les principales conséquences de type infectieux étant l’hépatite C et l’infection par le virus de l’immunodéficience humaine (VIH). Nous présenterons dans cet article les comportements d’injection et les comportements sexuels des injecteurs adolescents et jeunes adultes qui en font des personnes à risque pour ces deux infections. Nous y décrirons également des caractéristiques de ces jeunes injecteurs, qui sont liées à leur âge, dont il faut tenir compte dans l’élaboration de programmes de prévention : besoins liés au développement cognitif, physique et psychologique et aux contraintes d’ordre légal. Finalement, nous exposerons les résultats d’une vaste recherche que nous avons menée dans la littérature en vue de trouver des projets de prévention de l’infection par le VIH et de l’hépatite C qui ont répondu aux besoins spécifiques des jeunes injecteurs et qui ont fait l’objet d’une évaluation. Cette recherche a démontré qu’il existe très peu d’interventions satisfaisantes dans ce domaine. Selon nous, il est urgent que de telles interventions soient développées, évaluées et diffusées afin de contrer les épidémies de VIH et d’hépatite C qui sévissent chez les jeunes injecteurs.

LCR testing for gonorrhoea and chlamydia in population surveys and other screenings of low prevalence populations: coping with decreased positive predictive value

OBJECTIVE

Nucleic acid amplification tests have facilitated field based STD studies and increased screening activities. However, even with highly specific tests, the positive predictive value (PPV) of such tests may be lower than desirable in low prevalence populations. We estimated PPVs for a single LCR test in a population survey in which positive specimens were retested.

METHODS

The Baltimore STD and Behavior Survey (BSBS) was a population based behavioural survey of adults which included collecting urine specimens to assess the prevalence of gonorrhoea and chlamydial infection. Gonorrhoea and chlamydial infection were diagnosed by ligase chain reaction (LCR). Nearly all positive results were retested by LCR. Because of cost considerations, negative results were not confirmed. Predicted curves for the PPV were calculated for a single testing assuming an LCR test sensitivity of 95%, and test specificities in the range 95.0%-99.9%, for disease prevalences between 1% and 10%. Positive specimens were retested to derive empirical estimates of the PPV of a positive result on a single LCR test.

RESULTS

579 participants age 18-35 provided urine specimens. 20 (3.5%) subjects initially tested positive for chlamydial infection, and 39 (6.7%) tested positive for gonococcal infection. If positive results on the repeat LCR are taken as confirmation of a "true" infection, the observed PPV for the first LCR testing was 89.5% for chlamydial infection and 83.3% for gonorrhoea. This is within the range of theoretical PPVs calculated from the assumed sensitivities and specificities of the LCR assays.

CONCLUSIONS

Empirical performance of a single LCR testing approximated the theoretically predicted PPV in this field study. This result demonstrates the need to take account of the lower PPVs obtained when such tests are used in field studies or clinical screening of low prevalence populations. Repeat testing of specimens, preferably with a different assay (for example, polymerase chain reaction), and disclosure of the non-trivial potential for false positive test results would seem appropriate in all such studies.
