Comparison of methods for identifying ano-genital injury after consensual intercourse

Herpes simplex virus spreads rapidly in human foreskin, partly driven by chemokine-induced redistribution of Nectin-1 on keratinocytes

HSV infects keratinocytes in the epidermis of skin via nectin-1. We established a human foreskin explant infection model to investigate HSV entry and spread. HSV1 entry could only be achieved by the topical application of virus via high density microarray projections (HD-MAPs) to the epidermis, which penetrated beyond one third of its thickness, simulating in vivo microtrauma. Rapid lateral spread of HSV1 to a mean of 13 keratinocytes wide occurred after 24 hours and free virus particles were observed between keratinocytes, consistent with an intercellular route of spread. Nectin-1 staining was markedly decreased in foci of infection in the epidermis and in the human keratinocyte HaCaT cell line. Nectin-1 was redistributed, at the protein level, in adjacent uninfected cells surrounding infection, inducible by CCL3, IL-8 (or CXCL8), and possibly CXCL10 and IL-6, thus facilitating spread. These findings provide the first insights into HSV1 entry and spread in human inner foreskin in situ.

Frequency of Injuries to Women after Sexual Offense - Relevance of a Gynecology Examination

Introduction Up to a third of women worldwide report having experienced an act of sexual violence during their lifetime. The emergency gynecology department is often the first port of call for affected individuals. The aim of the current study was to evaluate the importance of gynecology examinations for women after a sexual offense and to evaluate the pattern of injuries sustained.

Methods This study is a retrospective single center analysis of the gynecology and forensic examination reports of all women examined for a suspected sexual offense in the central emergency department of a university hospital between 2013 and 2017 (n = 692). We evaluated genital and extragenital injury patterns, age, offender profile, time of offense, and substance use, as well as the administration of post-coital contraception and post-exposure prophylaxis for HIV.

Results The affected individuals had a mean age of 26 (12 – 91 years). Almost 75% of affected individuals presented within 24 hours of the reported sexual offense. Extragenital injuries were detected in 78.6% of patients and genital injuries in 28.5%. Overall, 20.1% of the women reported complete memory loss and 18.7% partial memory loss of the actual event. Risk factors for memory lapse were the consumption of alcohol and/or the (possibly non-consensual) administration of other substances acting on the central nervous system. A history of alcohol consumption by the victim (hazard ratio [HR] 1.95; 95% confidence interval [CI] 1.21 – 3.12, p = 0.006) and younger victims aged between 25 – 49 years (HR 1.75; 95% CI 1.07 – 2.85, p = 0.025) were associated with the occurrence of extragenital injuries. However, if the perpetrator was someone who was known to the affected individual, fewer extragenital injuries were sustained (HR 0.60; 95% CI 0.36 – 0.99, p = 0.046). Reports of genital injuries, associated with an older age of affected individuals and indications of anal penetration, resulted in more frequent administration of post-exposure prophylaxis (29.1% vs. 19.5%, p < 0.012) and hepatitis B (active) vaccination (40% vs. 28.5%, p < 0.028).

Conclusion Emergency gynecology examinations form a fundamental component of the medical care and the assessment of affected women after a sexual offense, since almost a third of victims sustain injuries to the genital region. In addition to a detailed complete physical examination and expert forensic documentation of physical and genital injuries, victims should also be offered psychological support which is easy for them to access.

Vaginal injuries after consensual sexual intercourse - a survey among office-based gynecologists in Hamburg, Germany

Studies on the occurrence of injuries following consensual sexual intercourse (CSI) among patients treated by office-based gynecologists are lacking. This survey aimed to assess the presence and medical relevance of vaginal injuries after CSI in gynecological office-based practice, associated risk factors, and their significance for forensic medical assessment practice. All office-based gynecologists in Hamburg, Germany (n = 316), were asked to fill in a one-page questionnaire via a fax survey. The questionnaire covered various aspects such as having observed CSI-related injuries, injury severity, risk factors, and concomitant factors (bleeding, need for surgical care, hospitalization). Response rate was 43.2% (n = 115). Overall, 83.5% of office-based gynecologists reported having observed vaginal injuries after CSI at least once and 59.1% repeatedly. Regarding maximum injury severity, 52.1% observed mucosal erosions, 32.3% mucosa penetrating injuries, and 14.6% injuries penetrating the vagina. Having observed bleeding was reported by 56.3%, 28.1% had to perform surgical suture care, and hospital admission was initiated by 20.8%. Menopause (37.5%), use of objects (19.8%), alcohol, and/or drug use (16.7%) were reported as the most frequently observed associated risk factors. Vaginal injuries after CSI have been observed by the majority of office-based gynecologists in Hamburg involving a wide spectrum of severity, including the necessity of surgical care and hospital admission. Complementing published work in clinical and emergency medicine, these findings are highly relevant to the forensic evaluation of injuries in an allegation of sexual assault, as the severity of a vaginal injury in this setting does not necessarily support a conclusion on the issue of consent.

Comparative Study of Acute Anogenital Injury Between Consensual and Nonconsensual Postmenarche Adolescents

ABSTRACT

In Thailand, sexual activity involving those under the legal age of consent may be legally and medically problematic, even if it is consensual. Thus, differentiating anogenital injury characteristics that occur during consensual versus nonconsensual acts with adolescent female subjects could aid legal advocates and improve health care and social support for these patients. Our study included postmenarche female patients having acute anogenital injuries after consensual and nonconsensual penetration. We found that nonconsenting patients had more cases of anogenital injury than consenting (69.8% vs 55.5%), with at least 1 abrasion, contusion, laceration, labia major or minor injury, and external or internal site injury. Both consensual and nonconsensual cases had the same common sites for injury type, reflecting the same injury mechanism; prior sexual intercourse was a significant protective factor against some anogenital injury prevalence, types, and sites for both groups. Adolescents forced into nonconsensual acts had more nonanogenital injuries. Looking at factors such as age, prior sexual activity history, and use of condom and/or contraceptive pills, it is very clear that early sexual education, particularly around consent, is critically needed in Thailand for the best interests of adolescents and children so that they and/or their guardians can access the health and legal resources required.

Female genital injury-which findings have to be considered physiological using colposcopy with and without toluidine blue dye?

This study aimed to assess the validity and efficacy of blue dye in colposcopic assessment of genital injury in pre- and postmenopausal women with and without history of consensual sexual intercourse. Two hundred women were prospectively enrolled and examined colposcopically with and without toluidine blue dye in order to detect and categorize genital lesions (laceration, bruise and abrasion). Examination of genital trauma was accomplished in a standardized way and findings were photo documented. A wide range of influencing factors with a potential impact on prevalence and nature of genital injury was recorded beforehand using a questionnaire. The frequency of diagnostic injury differed substantially depending on the examination technique, ranging from 9% using colposcopic magnification only to 28% with the additional use of toluidine blue dye. A vertical laceration affecting the posterior fourchette was the most frequent lesion detected (17%, n = 32). Menopausal status seems to have significant impact on genital injury prevalence (p = 0.0165), as 42% (16/ 38) of postmenopausal compared to 24% (36/ 151) of premenopausal women had at least one genital lesion. Furthermore, vaginal medication (p = 0.0369), vaginal dryness (p = 0.0228), dyspareunia (p = 0.0234) and low frequency of sexual intercourse (p = 0.0022) were found to significantly correlate with the presence of genital lesions. According to our findings, standardized colposcopy in combination with toluidine blue dye facilitates accurate assessment of genital lesions. Genital trauma situated at another site than the posterior part of the vaginal introitus seems to be uncommon after consensual intercourse.

Discriminating between consensual intercourse and sexual assault: Genital-anal injury pattern in females

BACKGROUND

Assessment of genital-anal (GA) injuries following sexual assault promotes health and assists prosecutors to build a case. The pattern of injuries may help differentiate between consensual and non-consensual intercourse, bolster the survivors' credibility, and increase prosecutions in sexual assault cases.

OBJECTIVES

To identify the constellation of G-A injury-related characteristics that most effectively discriminated between consensual sexual intercourse and sexual assault in females when controlling for intercourse-related variables.

METHODS

We employed a comparative study with two groups: a prospective cohort group with consensual participants and a group derived from an existing sexual assault registry. In the prospective cohort, we performed a sexual assault forensic examination at baseline and following consensual sexual intercourse with females ≥21 years. We compared their injury patterns to the injury records of females ≥21 years who were sexual assaulted.

RESULTS

We enrolled a sample of 834 females: 528 consensual (63.3%) participants and 306 non-consensual (36.7%) registry cases. After controlling for race/ethnicity, age, and time between intercourse and examination, logistic regression analyses showed that the presence of an external genital tear increased the odds of non-consensual intercourse more than two times (adjusted odds ratio [AOR] = 2.70, 95% CI = 1.28-5.56). Logistic regression analyses also showed that the odds of non-consensual sexual intercourse were significantly greater with a lower prevalence and frequency of external and internal genital redness, lack of condom use and lubrication, and presence of anal penetration. Latent class analysis identified high and low G-A injury prevalence subgroups among both consensual and non-consensual samples. One subset of results emerged that may be indicative of non-consensual as compared to consensual intercourse: a higher prevalence of external genital and anal tears.

CONCLUSION

External genital tears occurred more frequently in the non-consensual sample and increased the odds of non-consensual intercourse more than two times. Anal tears, swelling, and ecchymosis and anal penetration were markers for non-consensual intercourse and should increase suspicion for lack of consent.

HIV Pathogenesis in the Human Female Reproductive Tract

PURPOSE OF REVIEW

Women remain disproportionately affected by the HIV/AIDS pandemic. The primary mechanism for HIV acquisition in women is sexual transmission, yet the immunobiological factors that contribute to HIV susceptibility remain poorly characterized. Here, we review current knowledge on HIV pathogenesis in women, focusing on infection and immune responses in the female reproductive tract (FRT).

RECENT FINDINGS

We describe recent findings on innate immune protection and HIV target cell distribution in the FRT. We also review multiple factors that modify susceptibility to infection, including sex hormones, microbiome, trauma, and how HIV risk changes during women's life cycle. Finally, we review current strategies for HIV prevention and identify barriers for research in HIV infection and pathogenesis in women. A complex network of interrelated biological and sociocultural factors contributes to HIV risk in women and impairs prevention and cure strategies. Understanding how HIV establishes infection in the FRT can provide clues to develop novel interventions to prevent HIV acquisition in women.

Minimally invasive search for a missing vibrator

Objective

To report a unique surgical procedure that was utilized to locate a missing vibrator in the pelvis of a patient. Emergency room admissions and surgery secondary to the malfunctioning of devices intended for sexual stimulation are extremely common. Emergency room staff of hospitals in the United States usually are skilled in the detection and removal of these devices. Occasionally, surgical intervention is warranted if the device enters a cavity that cannot safely be explored in the emergency room setting. We report a case of a vibrator that was lost during sexual activity. A flat plate X-ray showed it to be in the abdominal cavity. Careful questioning of the patient revealed that the device had an unusually small diameter. Surgical intervention showed that the device ultimately ended up in the bladder without causing traumatic injury.

Methods

We created a narrated video to demonstrate the surgical procedure (Canadian Task Force Classification III).

Results

Laparoscopy and cystoscopy were used to visualize and successfully remove the device. The patient recovered uneventfully.

Conclusion

Following laparoscopic confirmation of the location of the device, it was removed via cystoscopy. This case demonstrates how background information, such as the size of the missing device in this case, can be critical to providing high quality patient care.

Unusual Case of a Missing Vibrator Device in the Pelvis

Emergency room admissions and surgery secondary to the malfunctioning of devices intended for sexual stimulation are extremely common. Emergency room staff in the United States are commonly skilled in the detection and removal of some of these frequent occurrences. Occasionally, surgical intervention can be warranted if the device enters a cavity that cannot safely be explored in the emergency room setting. We report a case of a vibrator which was lost during sexual activity and appeared on flat plate X-ray to be in the abdominal cavity. A careful history showed that the device was of an unusually narrow diameter, and surgical intervention showed the device ultimately ended up in the bladder without traumatic injury. Following laparoscopic confirmation of the device's location in the bladder, cystoscopic removal was performed and the patient recovered uneventfully.

Understanding rates of genital-anal injury: Role of skin color and skin biomechanics

PURPOSE

A series of studies suggest that non-Hispanic White women have significantly more injuries than non-Hispanic Black women after sexual assault and consensual sexual intercourse. One explanation for this difference is that the degree of skin protection may vary as skin mechanics and skin pigmentation vary. The aim of the study was to determine the association among genital-anal injury, skin color, skin viscoelasticity and skin hydration in women following consensual sexual intercourse when controlling for age, smoking history, body mass index (BMI), sun exposure, and health status.

PROCEDURES

We employed a prospective cohort study design to enroll women 21 years of age or older at two study sites. They underwent two data collection sessions, baseline and follow-up after consensual sexual intercourse. Baseline genital-anal injury identification occurred with a standard forensic examination (direct visualization, nuclear staining with toluidine blue contrast, and colposcopy examination) and measurements of other variables (skin color, skin viscoelasticity, skin hydration, age, smoking history, body mass index [BMI], sun exposure, and health status). Participants were then asked to have consensual sexual intercourse with a male partner of their choice and to return for a second forensic examination for injury detection. Genital-anal injury was regressed on skin color, skin viscoelasticity, skin hydration, age, smoking history, BMI, sun exposure, and health status.

FINDINGS

We enrolled 341 participants, 88 non-Hispanic White (25.8%), 54 non-Hispanic Black (15.8%), 190 Hispanic/Latina (55.7), and 9 Other Identities (2.6%). At baseline the genital-anal injury prevalence was 57.77% and at follow-up after consensual sexual intercourse, injury prevalence was 72.73%. External genital injury prevalence was associated with increased L* (lightness) values (Adjusted Odds Ratio [AOR] = 1.98, 95% Confidence Interval [CI] = 1.03, 4.04) and decreased skin elasticity (AOR = 0.96, 95% CI = 0.93, 0.99) at baseline. Increased skin hydration was associated with a significantly higher frequency of external, internal, anal, and total genital-anal injuries (Adjusted Rate Ratio [ARR] > 1.27) at follow-up. Also at the follow-up examination, Hispanic/Latina participants had significantly lower external genital and total genital-anal injury prevalence and frequency as compared to non-Hispanic White participants (AOR < 0.40).

CONCLUSIONS

Our findings provide qualified support for the importance of skin color during the forensic examination. Women with lighter skin tones may have skin that is more easily injured than women with darker tones. In contrast, external genital injuries may be more easily identified in women with light as compared to dark skin, a situation that is important in both the health care and criminal justice systems. Additionally, women with decreased viscoelasticity and increased hydration may be more easily injured. These findings support the need to develop forensic procedures that are effective in people across the range of skin colors and to interpret forensic findings considering the innate properties of the skin.

Child sexual abuse: The significance of the history and testifying on non-confirmatory findings

BACKGROUND

Despite numerous studies and publications, there is still a common expectation that a medical assessment can confirm or rule out child sexual abuse (CSA). The truth is that CSA can never be ruled out and can seldom be confirmed on clinical grounds.

AIM

The objective of this article was to suggest which aspects to consider when the expert medical witness in a CSA case needs to explain why CSA can seldom be confirmed and can never be ruled out. The importance of a sound medical and medico-legal history was discussed because the history was generally the only positive 'finding' of the assessment of children who have possibly been abused.

METHOD

Authoritative sources were used to support the explanation of reasons for an absence of corroborative clinical findings in CSA, as defined by the World Health Organization. The authors structured the individual sections by providing a background on which to base the testimony. They then summarised the clinical forensic significance of the information which should be offered in the courts and which should reflect on the court records, to be taken into account in the eventual decision, which will be made by the court.

RESULTS

A guideline was provided for answering questions frequently posed to the expert witness in child abuse cases where there were no positive findings.

CONCLUSION

A structure for the explanation of reasons for a normal clinical examination when evaluating children who may have been sexually abused may reduce the discomfort of medical witnesses and improve the quality of expert medical testimony.

Genitoanal Injury in Sexually Assaulted Adult Women: Six-Year Retrospective in Bangkok

Sexual assault persists as a global problem. Even when sexual assault does not result in obvious visible wounds, genitoanal injury must be evaluated because it is often pertinent for legal outcomes. Macroscopic ("naked eye") examination is valuable when colposcope is not available or when patients do not consent. This study reviewed the genitoanal injuries of 117 sexually assaulted adult women evaluated macroscopically. Genitoanal injury prevalence was 47%, and nongenitoanal injury prevalence was at 44%. The most common injury type was abrasion, and the most common site was posterior fourchette. Most injury patterns were singular. The number of women who did not report a history of sexual intercourse in the sample and usage of fingers/palm during assault may have affected pattern and/or injury type. There was a significant relationship between hymenal old tear below the 3- to 9-o'clock area and prior sexual intercourse. Factors related to genitoanal injury were prior sexual intercourse, vaginal delivery, and spermatozoa detection. In conclusion, all sexually assaulted women should be encouraged to have a pelvic examination: nothing overtly visible does not mean that nothing happened.

Comparison of Injury Patterns in Consensual and Nonconsensual Sex: Is It Possible to Determine if Consent was Given?

Matters of sexual consent and sexual assault are hotly debated issues among professionals and laypersons alike. A widespread misconception of sexual assault is that most victims of sexual assault sustain significant physical trauma. It is the purpose of this review article to compare the patterns of physical injury (both genital and extragenital) in victims of sexual assault and participants of consensual sex to conclude if physical injury alone can indicate whether consent was given. Interpretations of injury have great forensic significance as it can influence the outcome of sexual assault cases. Several articles indicate that extragenital injuries are commonly found in sexual assault victims (46%-82%) and that most of such injuries are deemed minor. Articles report a wide range of genital injury detection rates in both sexual assault victims (6%-87%) and consensual sex participants (6%-73%). Usage of different examination techniques may partly explain the wide range of detection rates reported. Out of all those who sustained genital injuries, only a small portion of people required hospitalization. In both consensual and sexual assault cases, genital injuries in the 6 o'clock position were most common. Studies of genital injury lacked standardization of factors that significantly influence the results, such as time to examination after sex, examination techniques, and injury severity scales. Therefore, medicolegal personnel should be aware that sexual assault victims can present with a wide range of physical trauma and should avoid relying on physical trauma alone to conclude whether consent was present.

Tenofovir Inhibits Wound Healing of Epithelial Cells and Fibroblasts from the Upper and Lower Human Female Reproductive Tract

Disruption of the epithelium in the female reproductive tract (FRT) is hypothesized to increase HIV infection risk by interfering with barrier protection and facilitating HIV-target cell recruitment. Here we determined whether Tenofovir (TFV), used vaginally in HIV prevention trials, and Tenofovir alafenamide (TAF), an improved prodrug of TFV, interfere with wound healing in the human FRT. TFV treatment of primary epithelial cells and fibroblasts from the endometrium (EM), endocervix (CX) and ectocervix (ECX) significantly delayed wound closure. Reestablishment of tight junctions was compromised in EM and CX epithelial cells even after wound closure occurred. In contrast, TAF had no inhibitory effect on wound closure or tight junction formation following injury. TAF accumulated inside genital epithelial cells as TFV-DP, the active drug form. At elevated levels of TAF treatment to match TFV intracellular TFV-DP concentrations, both equally impaired barrier function, while wound closure was more sensitive to TFV. Furthermore, TFV but not TAF increased elafin and MIP3a secretion following injury, molecules known to be chemotactic for HIV-target cells. Our results highlight the need of evaluating antiretroviral effects on genital wound healing in future clinical trials. A possible link between delayed wound healing and increased risk of HIV acquisition deserves further investigation.

Anogenital and Physical Injuries in Adolescent Sexual Assault Patients: The Role of Victim-Offender Relationship, Alcohol Use, and Memory Impairment

Prior research has documented high rates of anogenital and physical injuries among adolescent sexual assault patients. Although a number of factors related to rates of injury detection in adolescents have been identified, there may be additional features of the assault that are disclosed in the patient history that could be important indicators of injury risk. The purpose of the current study was to expand this literature by examining whether factors that are salient in sexual assaults committed against adolescents-victim-offender relationship, substance use, and memory impairment-are associated with documented anogenital and physical injury rates. Results indicated that victim-offender relationship, substance use, and assault memory are significantly related to the number of anogenital injuries and, particularly, the number of physical injuries detected in adolescent sexual assault patients. These results highlight the importance of a comprehensive patient history, including assessment of alcohol and drug use and memory impairment, to guide the medical forensic examination.

Exploring Genitoanal Injury and HIV Risk Among Women: Menstrual Phase, Hormonal Birth Control, and Injury Frequency and Prevalence

BACKGROUND

Genital, anal, and oral injuries sustained from sexual intercourse may explain HIV transmission among women. We determined the variability in genitoanal injury frequency and prevalence in women after consensual sexual intercourse, exploring the role of menstrual phase and hormonal birth control.

METHODS

We used a longitudinal observational design with a convenience sample of 393 women aged 21 years and older. Participants had a baseline interview with gynecological examination, followed by consensual sexual intercourse with a male partner and a second gynecological examination. We analyzed injury prevalence with logistic regression and injury frequency with negative binomial regression among women who were (1) menstrual, not using hormonal birth control, (2) menstrual, using hormonal birth control, or (3) menopausal. We also compared injury among menstrual women in the follicular, ovulatory, and luteal phases.

FINDINGS

Women using hormonal birth control had 38% more external genitalia injuries [adjusted rate ratio (ARR) = 1.38, P = 0.030] and more than twice the anal injuries (ARR = 2.67, P = 0.005) as the nonhormonal birth control menstruating group. Menopausal women had more than 3 times the anal injuries (ARR = 3.36, P = 0.020) than those in the nonhormonal menstrual group. Among menstrual women, those in the follicular phase had a greater prevalence and frequency of external genitalia injuries than those in other phases.

INTERPRETATION

Increased rates of postcoital genitoanal injuries are noted among women using hormonal birth control and/or in the follicular phase of menstruation. Biological factors that influence women's risk for HIV warrant further investigation.

The Exclusion of Sperm Donation on the Basis of Sexual Practices: Time for a Policy Update

Currently, both the U.S. Food and Drug Administration and American Society for Reproductive Medicine exclude sperm donation from men who have sex with men. The recommended screening includes questioning donors about their sexual practices and performing a physical examination to look for signs of anal intercourse in addition to standard human immunodeficiency virus (HIV) laboratory testing. The rationale cited is concern over increased risk of HIV transmission in this higher prevalence population. We were unable to find evidence that excluding men who have sex with men or those with signs of anal intercourse on physical examination decreases the false-negative rate of laboratory testing. Current policy allows for men who have sex with men to be prohibited from donating sperm for the use of gestational carriers and therefore discriminates against this population for whom assisted reproductive technology may be their only means of genetic reproduction. We suggest policy revision to include the most advanced HIV laboratory tests and eliminating exclusionary demographics as part of screening.

Women's Preferences for Penis Size: A New Research Method Using Selection among 3D Models

Women's preferences for penis size may affect men's comfort with their own bodies and may have implications for sexual health. Studies of women's penis size preferences typically have relied on their abstract ratings or selecting amongst 2D, flaccid images. This study used haptic stimuli to allow assessment of women's size recall accuracy for the first time, as well as examine their preferences for erect penis sizes in different relationship contexts. Women (N = 75) selected amongst 33, 3D models. Women recalled model size accurately using this method, although they made more errors with respect to penis length than circumference. Women preferred a penis of slightly larger circumference and length for one-time (length = 6.4 inches/16.3 cm, circumference = 5.0 inches/12.7 cm) versus long-term (length = 6.3 inches/16.0 cm, circumference = 4.8 inches/12.2 cm) sexual partners. These first estimates of erect penis size preferences using 3D models suggest women accurately recall size and prefer penises only slightly larger than average.

[Practical guide to the examination and interpretation of genital lesions of minor female victims of sexual assault]

Through a comprehensive review of the literature on sexual assault, the authors propose to clarify the different stages of the exam and help the practitioner to the forensic interpretation of lesions. The authors describe the basic principles that make consensus in how to interview victims in order to increase the reliability of the information collected. The various medical data that must be collected allowing to guide diagnosis (urogenital symptoms, sexual behaviour disorder) or facilitate the interpretation of lesions (age of puberty, use of tampons…) are specified as well as the different positions of examination and their association to other complementary techniques (Foley catheter, colposcopy, toluidine blue). The authors present a simple decision tree that can help the practitioner to interpret the laceration of the hymen. They detail the description and forensic interpretation of all genital lesions that may be encountered as a result of sexual assault, and the pitfalls to avoid. Finally, two main problems in the interpretation of lesions are described, the absence of injury after penetration and the accidental genital lesions.

Post-coital genital injury in healthy women: A review

Female genital injury following penile sexual intercourse in healthy women is a matter of importance and debate in many parts of society. However, the literature on the subject is sparse. There are a few studies regarding minor injury that does not require treatment in adult, pre-menopausal women, a single study of adolescent women, and none regarding post-menopausal women. Larger lesions requiring treatment are described casuistically. The purpose of this article is to provide a short, easy-to-read review of the literature regarding the prevalence and nature of female genital injury following consensual sexual intercourse in otherwise healthy women.

Evaluation of anogenital injuries using white and UV-light among adult volunteers following consensual sexual intercourse

OBJECTIVES

New clinical forensic examination techniques for sexual assaults have not been introduced over the last few decades. We evaluated the benefit of ultraviolet light compared to white light for detecting minor anogenital injuries and scars, following consensual sexual intercourse among adult volunteers.

DESIGN

A prospective study comparing female genital findings utilising white and ultraviolet light. A colposcopy with photographic documentation was used.

SETTING

Personal invitation to healthcare students, hospital employees or acquaintances to volunteer for a gynecological examination, with a focus on clinical forensic aspects.

PARTICIPANTS

Eighty-eight adult female volunteers were recruited for the study. The examination was performed after consensual intercourse. Age ranged from 20 to 52 years (median 26.5 years).

MAIN OUTCOME MEASURES

Presence of acute findings and scars in the genital area using white and UV-light.

RESULTS

Acute genital injury rate was 14.8% under white light colposcopy and 23.0% using UV light. Submucosal hemorrhages in the genital area were documented significantly better under UV-light than white light (14.9% vs. 6.8%; p=0.016), whereas petechiaes (4.5%) and abrasions (2.3%) were detected using either method. UV-light revealed significantly more often delivery-associated genital scars compared to white light (39.8% vs. 31.8%; p=0.016). Furthermore, 10 out of 31 (33.3%) women had no residual anogenital skin or mucosal surface findings, despite a prior episiotomy or rupture of the vaginal outlet wall during delivery, supporting its enormous ability to heal even after major trauma.

CONCLUSIONS

UV-light may provide additional value for the evaluation of physical findings in clinical forensic examinations after sexual assault, and is especially useful in detecting otherwise invisible early submucosal hemorrhages and scars.

Macroscopically detected female genital injury after consensual and non-consensual vaginal penetration: a prospective comparison study

OBJECTIVE

The aim of this study was to compare the prevalence, type and pattern of macroscopically detected female genital injury after consensual and non-consensual vaginal penetration to further an understanding of the forensic significance of genital injury in women reporting sexual assault. A secondary aim was to identify any effect of a range of possible variables upon the likelihood of genital injury resulting from vaginal penetrative sexual intercourse.

STUDY DESIGN

Two groups of reproductive age women (aged 18-45 years) were prospectively recruited within 72 h of a single episode of vaginal penetrative sex, and macroscopically examined for the presence of bruises, abrasions and lacerations at twelve external and internal genital sites. Forty one women who presented for forensic examination after reporting a sexual assault to police were recruited to the non-consensual group and 81 women who presented for routine cervical screening or with sexual health concerns to a primary health care service to the consensual group. Each group was examined by a different group of doctors, all of whom were experienced in both forensic genital examination and gynaecological examination of healthy and diseased sexually active women. Data collection and examination protocols were the same for both groups.

RESULTS

The key finding was a statistically significant difference in genital injury prevalence between women who were vaginally penetrated non-consensually and consensually; 53.7% of the non-consensual group (22/41) and 9.9% of the consensual group (8/81) were found to have at least one genital injury [OR 10.57, CI (4.07, 27.42), p < 0.00001]. Penetration with finger/s and possible pre-existing genital 'infection' were found to be significantly associated with the presence of injury in the univariate analysis after adjusting for consent. Logistic regression demonstrated that women penetrated without consent were 19.5 times more likely to sustain at least one genital injury, than those penetrated consensually [OR 19.53, CI (6.03, 63.24)] and that a penetration scenario that included finger/s was 4.2 times more likely to result in at least one genital injury than penetration without finger involvement [OR 4.25, CI (1.42, 12.78)], when controlling for other variables in the model. Whilst a comparatively low injury prevalence in the consensual group limited interpretation, results revealed possible differences in genital injury typology and pattern resulting from non-consensual and consensual vaginal penetration. Lacerations were seen after both consensual and non-consensual vaginal penetration, while abrasions and bruises were seen exclusively in the non-consensual group.

CONCLUSION

This study demonstrated a significant consent group difference in genital injury prevalence and the highest macroscopically detected genital injury prevalence rate resulting from non-consensual vaginal penetration identified to date. Results also indicate that vaginal penetration with finger/s increases the likelihood of sex-related injury. The difference in type of injury sustained as a result of non-consensual and consensual vaginal penetration was an unexpected finding, and warrants further investigation. These results highlight the importance of a standardised means of detecting genital injury based on consistent injury definitions, examination protocols, and examiner experience and suggest that macroscopic genital examination may be uniquely placed to detect consent group differences in injury typology and pattern if they exist.

Greentree white paper: sexual violence, genitoanal injury, and HIV: priorities for research, policy, and practice

The links between sexual violence, genitoanal injury, and HIV are understudied but potentially significant for understanding the epidemic's disproportionate impacts on young women and girls, particularly in sub-Saharan Africa, other hyperendemic areas, and conflict-affected regions. A Scientific Research Planning Meeting was convened by the Social Science Research Council at the Greentree Foundation in New York, March 19-20, 2012, bringing together an interdisciplinary group of researchers, clinicians, and policy makers to identify knowledge needs and gaps in three key areas: (1) the role of genitoanal injury on HIV transmission, acquisition, and pathogenesis; (2) the influence of sex and age-related anatomic characteristics on HIV transmission, acquisition, and pathogenesis; and (3) the role of heterosexual anal intercourse in HIV transmission. This article reflects the consensus that emerged from the Greentree Meeting regarding priority scientific research questions in these three areas, associated data collection and measurement challenges and opportunities, and implications for policy and practice.

Sexual activity-related emergency department admissions: eleven years of experience at a Swiss university hospital

PRINCIPALS

Most people enjoy sexual intercourse without complications, but a significant, if small, number need to seek emergency medical help for related health problems. The true incidence of these problems is not known. We therefore assessed all admissions to our emergency department (ED) in direct relation to sexual intercourse.

METHODS

All data were collected prospectively and entered into the ED's centralised electronic patient record database (Qualicare, Switzerland) and retrospectively analysed. The database was scanned for the standardised key words: 'sexual intercourse' (German 'Geschlechtsverkehr') or 'coitus' (German 'Koitus').

RESULTS

A total of 445 patients were available for further evaluation; 308 (69.0%) were male, 137 (31.0%) were female. The median age was 32 years (range 16-71) for male subjects and 30 years (range 16-70) for female subjects. Two men had cardiovascular emergencies. 46 (10.3%) of our patients suffered from trauma. Neurological emergencies occurred in 55 (12.4%) patients: the most frequent were headaches in 27 (49.0%), followed by subarachnoid haemorrhage (12, 22.0%) and transient global amnesia (11, 20.0%). 154 (97.0%) of the patients presenting with presumed infection actually had infections of the urogenital tract. The most common infection was urethritis (64, 41.0%), followed by cystitis (21, 13.0%) and epididymitis (19, 12.0%). A sexually transmitted disease (STD) was diagnosed in 43 (16.0%) of all patients presenting with a presumed infection. 118 (43.0%) of the patients with a possible infection requested testing for an STD because of unsafe sexual activity without underlying symptoms.

CONCLUSIONS

Sexual activity is mechanically dangerous, potentially infectious and stressful for the cardiovascular system. Because information on ED presentation related to sexual intercourse is scarce, more efforts should be undertaken to document all such complications to improve treatment and preventative strategies.

Forensic medical examination of adolescent and adult victims of sexual violence

The acute care and examination of a victim of sexual violence must be carried out by a competent forensic examiner in a setting appropriate for crisis intervention, forensic evidence collection, and medical follow up. The aim of forensic evidence and biological material collection is to document an alleged physical or sexual contact between individuals and to corroborate the victim's and the assailant's history. This is why the forensic examiner is expected to be objective and in possession of specialised technical and scientific skills. These skills are addressed and recommendations are made on how to carry out a forensic examination. This includes medical and assault history, top-to-toe examination, biological material collection, and documenting injuries while obtaining the chain of custody. Yet, consensus on time limitations for forensic evidence collection is lacking. Available forensic evidence has been shown to benefit prosecution. To meet the legal system's needs, an interpretation of the findings in a written legal report is mandatory.

Sexual assault injuries and increased risk of HIV transmission

Sexual assault and HIV are coexisting public health problems. Sexual assault may increase HIV transmission risk through diverse mechanisms, such as infliction of anal, oral, and genital injuries by penile, digital, or object penetration, extragenital trauma, concurrent sexually transmitted infections, condom use, and whether the perpetrator was circumcised.

Injuries from intimate partner and sexual violence: Significance and classification systems

While intimate partner violence (IPV) and sexual violence (SV) are highly associated with injury, the healthcare and legal significance of these injuries is controversial.

PURPOSE

Herein we propose to explore the significance of injury in IPV and SV and examine the current status of injury classification systems from the perspectives of the healthcare and criminal justice systems. We will review current injury classification systems and suggest a typology of injury that could be tested empirically.

FINDINGS

Within the published literature, we found that no commonly accepted injury typology exists. While nuanced and controversial issues surround the role of injury detection in the sexual assault forensic examination, enough evidence exists to support the continued pursuance of a scientific approach to injury classification. We propose an injury typology that is measurable, is applicable to the healthcare setting and criminal justice system, and allows us to use uses a matrix approach that includes a severity score, anatomic location, and injury type. We suggest a typology that might be used for further empirical testing on the validity and reliability of IPV and SV injury data.

CONCLUSION

We recommend that the community of scientists concerned about IPV and SV develop a more rigorous injury classification system that will improve the quality of forensic evidence proffered and decisions made throughout the criminal justice process.

Nature, frequency and duration of genital lesions after consensual sexual intercourse--implications for legal proceedings

OBJECTIVE

The purpose of this study was to make a normative description of the nature and duration of genital lesions sustained during consensual sexual intercourse, using the three most commonly used techniques; visualisation using the naked eye, colposcopy and toluidine blue dye followed by colposcopy.

METHODS

Ninety eight women were examined within 48 h of consensual sexual intercourse. Fifty of the women were examined twice again within the following 7 days of sexual abstinence after the first examination.

RESULTS

The participants had a median age of 22.4 years and 88% were nulliparous. Lesions were frequent; 34% seen with the naked eye, 49% seen with colposcopy and 52% seen with toluidine blue dye and subsequent colposcopy. The lesions lasted for several days; the median survival times for lacerations were 24, 40 and 80 h, respectively.

CONCLUSIONS

The legal implications of these findings are that genital lesions by themselves do not corroborate a rape complaint. Genital lesions may, however, corroborate specific details of a case and should be documented as carefully as any other lesion in rape complaints.

Genital trauma in prepubertal girls and adolescents

PURPOSE OF REVIEW

To look critically at recent research articles that pertain to children and adolescents who present with genital injuries.

RECENT FINDINGS

Emerging evidence supports links to long-term psychological sequelae of child sexual abuse. Parents should be educated to instruct their children regarding types of child abuse and prevention. 'Medicalization' of female genital mutilation (FGM) by health providers, including 'cutting or pricking', is condemned by international organizations.

SUMMARY

Genital injuries whether accidental or intentional need to be reported with standardized terminology to allow for comparisons between reported outcomes. Motor vehicle accidents associated with pelvic fractures may result in bladder or urethral trauma. Adverse long-term psychosocial behaviors may be sequelae of child sexual abuse. FGM is willful damage to healthy organs for nontherapeutic reasons, and a form of violence against girls and women. Healthcare providers should counsel women suffering from the consequences of FGM, advise them to seek care, counsel them to resist reinfibulation, and prevent this procedure from being performed on their daughters.

Coming of age: reconstruction of heterosexual HIV-1 transmission in human ex vivo organ culture systems

Heterosexual transmission of human immunodeficiency virus-1 (HIV-1), from men to women, involves exposure to infectious HIV-1 in semen. Therefore, the cellular and molecular processes that underlie HIV-1 transmission are closely interconnected with fundamental principles of human reproductive biology. Human ex vivo organ culture systems allow experimental reconstruction of HIV-1 transmission, using human semen and premenopausal cervicovaginal mucosal tissue, with specific emphasis on the progression from exposure to development of primary HIV-1 infection. Clearly, an isolated piece of human tissue cannot duplicate the full complexity of events in natural infections, but with correct observation of conventional medical and ethical standards, there is no opportunity to study HIV-1 exposure and primary infection in young women. Human mucosal organ cultures allow direct study of HIV-1 infection in a reproducible format while retaining major elements of complexity and variability that typify community-based HIV-1 transmission. Experimental manipulation of human mucosal tissue both allows and requires acquisition of new insights into basic processes of human mucosal immunology. Expanding from the current foundations, we believe that human organ cultures will become increasingly prominent in experimental studies of HIV-1 transmission and continuing efforts to prevent HIV-1 infection at human mucosal surfaces.
