The relationship between sexual abuse and interstitial cystitis/painful bladder syndrome

Associations of abuse experiences in childhood/adolescence and adulthood to pain, sexual functioning, and mental health among women with urogenital pain

OBJECTIVE

Urogenital pain affects 14-25 % of women and is predicted by prior abuse. The purpose of this study was to investigate associations of abuse type (sexual, physical, emotional, verbal) and timing (childhood, adolescence, adulthood) on outcomes (depression, anxiety, pain, sexual functioning).

METHODS

Women (N = 350; age M = 48.44) presenting with pain at a tertiary women's urology center reported whether they had experienced each type of abuse at each time point and completed outcome measures.

RESULTS

Latent class analysis of abuse types and timings identified a 4-class solution which differed primarily in phase of life for which abuse types (verbal, emotional, and physical, but not sexual) were elevated: 1) little or no abuse throughout life (66.6 %), 2) childhood/adolescent abuse only (14.6 %), 3) adulthood abuse only (8.3 %), or 4) abuse across the life course (10.6 %). Statistical comparisons between classes revealed abuse throughout life or in childhood/adolescence only was associated with depression and abuse throughout life, with anxiety (p < .001, d = 0.48-1.40), compared to no abuse. However, abuse over life or in adulthood only, but not childhood/adolescent only, was associated with pain interference, pain intensity, and low sexual satisfaction (p < .05, d = 0.38-0.77).

CONCLUSION

These patterns suggest that when abuse occurs may matter differentially in terms of mental and physical health; abuse (especially emotional/verbal and physical) in both childhood and adulthood may predispose to poor mental health, whereas adulthood abuse may be more associated with pain and functioning. One should assess when abuse occurs-including adulthood-in addition to type of abuse to understand its association with outcomes.

"He was not interested in pain": The experience of pain in child sexual abuse as conveyed by adult survivors

Although extensive efforts have been dedicated to uncovering the close link between trauma and chronic pain, very few research efforts have investigated the lived experience of pain during and following trauma. This study delves into the complex and multifaceted experiences of physical pain among adults who experienced child sexual abuse (CSA), examining 29 detailed testimonies provided to the Israeli Independent Public Inquiry into CSA. Using qualitative thematic analysis, the research identifies and elaborates on three pivotal themes: pain as a distress signal, the internalization of pain, and the intermingling of physical and mental pain. Thus, the study findings capture the immediate physical pain experienced during abusive incidents, which serves as an involuntary alert to the self and, at times, to the broader environment about the trauma being experienced. The findings also explore how this acute response transforms into a chronic state, becoming an embedded part of survivors' daily lives, influencing personal and relational dynamics, often without visible scars but with profound internal implications. Lastly, the findings reveal the blurred lines between the participant's physical and psychological pain, illustrating how they express psychological distress through physical pain symptoms and how this affects their coping mechanisms. The study underscores the necessity of recognizing pain as a complex, enduring component of the CSA survivor's experience, highlighting the need for integrated therapeutic approaches that address the intertwined nature of posttraumatic mental symptoms and physical pain. This study advocates for a more nuanced understanding and acknowledgment of pain in CSA survivors, urging further research and adapted clinical practices to better support their recovery and well-being.

Diagnosis of Child Sexual Abuse

Child sexual abuse (CSA) is a widespread and alarming issue, with an estimated global prevalence of 12-13% (affecting 18% of girls and 8% of boys). Despite its prevalence, many physicians working with children have insufficient knowledge of the medical diagnosis of CSA. This lack of expertise, combined with the sensitive and complex nature of these cases, often hampers proper identification and management. Diagnosing CSA is particularly challenging and requires specialized skills. A majority of children assessed for suspected sexual abuse present with normal genital and anal findings, which complicates the diagnostic process. Barriers such as professional isolation, societal taboos, and the sensitive nature of the subject often result in diagnostic failures. Accurate medical history taking, diagnosis, and documentation of findings are essential for ensuring a precise diagnosis, safeguarding children, and supporting legal proceedings. However, achieving these goals remains elusive without standardized guidelines and adequately trained healthcare professionals. Training of professionals in observing and reporting child sexual abuse is badly needed. This review explores the current state of medical diagnosis in suspected cases of CSA. This article is based on a selective review of pertinent literature retrieved from various databases, including PubMed and the overall index of the Quarterly Update.

Thalamic Nucleus Reuniens Glutamatergic Neurons Mediate Colorectal Visceral Pain in Mice via 5-HT2B Receptors

Irritable bowel syndrome (IBS) is a common functional bowel disorder characterized by abdominal pain and visceral hypersensitivity. Reducing visceral hypersensitivity is the key to effectively relieving abdominal pain in IBS. Increasing evidence has confirmed that the thalamic nucleus reuniens (Re) and 5-hydroxytryptamine (5-HT) neurotransmitter system play an important role in the development of colorectal visceral pain, whereas the exact mechanisms remain largely unclear. In this study, we found that high expression of the 5-HT2B receptors in the Re glutamatergic neurons promoted colorectal visceral pain. Specifically, we found that neonatal maternal deprivation (NMD) mice exhibited visceral hyperalgesia and enhanced spontaneous synaptic transmission in the Re brain region. Colorectal distension (CRD) stimulation induced a large amount of c-Fos expression in the Re brain region of NMD mice, predominantly in glutamatergic neurons. Furthermore, optogenetic manipulation of glutamatergic neuronal activity in the Re altered colorectal visceral pain responses in CON and NMD mice. In addition, we demonstrated that 5-HT2B receptor expression on the Re glutamatergic neurons was upregulated and ultimately promoted colorectal visceral pain in NMD mice. These findings suggest a critical role of the 5HT2B receptors on the Re glutamatergic neurons in the regulation of colorectal visceral pain.

Intergenerational associations between childhood maltreatment, post-traumatic stress symptoms, and chronic pain in young adult offspring and their parents

Findings have revealed a strong link between exposure to child maltreatment (CM) and later chronic pain. Concurrently, other findings have been grounded in the understanding that CM consequences may not end with the exposed individual, rather, they extend to their offspring. However, little is known regarding the possible intergenerational transmission of chronic pain following CM. This study examines whether chronic pain among parents and their young adult offspring may be associated with parental exposure to CM. Three hundred ninety-three parent-offspring dyads (parents' mean age = 58, SD = 5.91 years; offspring's mean age = 27, SD = 3.91 years) completed self-report questionnaires, assessing CM (CTQ), posttraumatic stress (PTS) and disturbances in self-organisation (DSO) symptoms (ITQ), and chronic pain. CM was associated with chronic pain mediated by DSO symptoms among parents (indirect effect = 0.77; p = 0.007) and PTS symptoms among offspring (indirect effect = 0.285; p = 0.005). Offspring chronic pain was significantly associated with parental CM through two intergenerational paths: the mediation of parents' DSO symptoms and chronic pain (indirect effect = 0.298; p = 0.011), and through parents' PTS symptoms and offspring's PTS symptoms (indirect effect = 0.077; p = 0.004). This study's findings support the relevance of the intergenerational transmission of chronic pain following parental exposure to CM. Furthermore, the findings reveal complex PTS symptoms as a possible underlying mechanism for the intergenerational associations of chronic pain following CM.

Peritraumatic Pain in Child Maltreatment: A Systematic Literature Review

Extensive research has been conducted on the link between trauma, child maltreatment (CM), and chronic pain. Although the risk of suffering from chronic pain among CM survivors has been established, much less is known about the experience of pain during CM incidents or whether such peritraumatic pain sensations are associated with later chronic pain. This scoping review was conducted to synthesize the existing literature on pain during and a short time following CM (i.e., peritraumatic pain). Utilizing the preferred reporting items for systematic reviews and meta-analyses guidelines, the current review included 11 manuscripts, which met the following criteria: (a) refer to physical pain experienced during or a short time after CM, (b) were published in peer-reviewed journals, and (c) were written in English. The review demonstrated that most of the included studies were not intentionally focused on peritraumatic pain, the majority used qualitative research methods, and all were cross-sectional. Furthermore, although validated questionnaires are available, most of the studies did not utilize such measures. Those that intentionally reported pain demonstrated its high intensity and prevalence in CM incidents, indicating that pain is inherently embedded in the experience of maltreatment. The findings spotlight an underdeveloped research realm on a phenomenon that may hold significant empirical, clinical, and legal implications. Research endeavors should initiate interdisciplinary bodies of knowledge to establish well-validated research methodologies that properly quantify peritraumatic pain in trauma and CM.

Peritraumatic Pain in Child Sexual Abuse: Children's Descriptions of Pain as Conveyed in Their Testimonies Following Child Sexual Abuse

The literature on child sexual abuse (CSA) has contributed significantly to the understanding of its characteristics, epidemiology, and consequences. Considerably less attention has been dedicated, however, to the subjective experiences of the abused children, and more specifically to their experiences of pain. The current study explored the way children perceive and describe pain during and shortly following incidents of sexual abuse. The sample was comprised of 35 transcripts of forensic interviews following alleged CSA. Thematic analysis of the children's narratives identified three themes: (a) pain during the abusive incidents, described using words indicating its intensity and quality; (b) pain shortly after the abusive incidents, including weeks later, and (c) pain as embedded within the complex dynamic with perpetrator. The children struggled to localize the pain, mainly using words such as "inside" and "deep." Moreover, they testified that in the course of the abusive incidents, they were often silenced when trying to communicate their pain to the perpetrators. The children's narratives provided us with a unique opportunity to learn about the pain not only during the abusive incidents but also following it. Additionally, children described suffering from pain in areas that were not directly injured during the CSA incidents, mainly referring to the head, abdomen and legs. The discussion addresses the potential intervening factors in peritraumatic CSA pain, as well as its potential links with chronic post-traumatic physical and mental morbidity. This study illuminates the necessity to address the complicated links between short- and long-term physical, emotional, cognitive, and interpersonal manifestations of CSA.

Interpersonal violence and painful bladder symptoms in community-dwelling midlife to older women

BACKGROUND

Women are more likely to present with genitourinary complaints immediately after exposure to interpersonal violence, but little is known about the long-term effects of violence on women's urologic health, including their susceptibility to bladder pain and infections.

OBJECTIVE

To determine whether lifetime interpersonal violence exposure and current posttraumatic stress disorder (PTSD) symptoms are associated with the prevalence or severity of painful bladder symptoms and a greater lifetime history of antibiotic-treated urinary tract infections in community-dwelling midlife and older women.

STUDY DESIGN

We examined the cross-sectional data from a multiethnic cohort of community-dwelling women aged 40 to 80 years enrolled in a northern California integrated healthcare system. Women completed structured self-report questionnaires about their past exposure to physical and verbal/emotional intimate partner violence and sexual assault. The symptoms of PTSD were assessed using the PTSD checklist for the Diagnostic and Statistical Manual of Mental Disorders-Fourth Edition, Civilian version. Additional structured self-report measures assessed the current bladder pain, other lower urinary tract symptoms, and the history of antibiotic-treated urinary tract infections. Multivariable logistic regression models examined self-reported interpersonal violence exposure history and current PTSD symptoms in relation to current bladder pain and antibiotic-treated urinary tract infection history.

RESULTS

Among 1974 women (39% non-Latina White, 21% Black, 20% Latina, and 19% Asian), 22% reported lifetime interpersonal violence exposure, 22% reported bladder pain, and 60% reported a history of ever having an antibiotic-treated urinary tract infection. Lifetime experiences of sexual assault (odds ratio, 1.39; [95% confidence interval, 1.02-1.88]) and current PTSD symptoms (odds ratio, 1.96; [95% confidence interval, 1.45-2.65]) were associated with current bladder pain. A lifetime experience of physical intimate partner violence was associated with having a urinary tract infection at any time in life previously (odds ratio, 1.38; [95% confidence interval, 1.00-1.86]), as was emotional intimate partner violence (odds ratio, 1.88; [95% confidence interval, 1.43-2.48]), sexual assault (odds ratio, 1.44; [95% confidence interval, 1.09-1.91]), and current PTSD symptoms (odds ratio, 1.54; [95% confidence interval, 1.16-2.03]).

CONCLUSION

In this ethnically diverse, community-based cohort, lifetime interpersonal violence exposures and current PTSD symptoms were independently associated with current bladder pain and the lifetime history of antibiotic-treated urinary tract infections in midlife to older women. The findings suggest that interpersonal violence and PTSD symptoms may be underrecognized markers of risk for urologic pain and infections in women, highlighting a need for trauma-informed care of these issues.

The Risks, Invisibility, and Health Issues Facing Women Veterans Who Are Homeless

Women veterans may experience a variety of traumatizing events and conditions before, during, and after their military service, such as intimate partner violence, military sexual trauma, moral injury, and posttraumatic stress disorder. These experiences put them at greater risk for significant behavioral and physical health sequelae, which can be associated with difficulty with civilian reintegration and complexities around homelessness. Homeless women military veterans are often uncounted, undergo different environmental situations than their male counterparts, and are vulnerable to sexual violence and unintended pregnancies. Identifying homeless women military veterans is an important first step; otherwise, they remain "invisible." Comprehensive, collaborative, interdisciplinary health care in which trust is established and care is holistic and individualized will produce the most optimal outcomes.

Psychological/mental stress-induced effects on urinary function: Possible brain molecules related to psychological/mental stress-induced effects on urinary function

Exposure to psychological/mental stress can affect urinary function, and lead to and exacerbate lower urinary tract dysfunctions. There is increasing evidence showing stress-induced changes not only at phenomenological levels in micturition, but also at multiple levels, lower urinary tract tissues, and peripheral and central nervous systems. The brain plays crucial roles in the regulation of the body's responses to stress; however, it is still unclear how the brain integrates stress-related information to induce changes at these multiple levels, thereby affecting urinary function and lower urinary tract dysfunctions. In this review, we introduce recent urological studies investigating the effects of stress exposure on urinary function and lower urinary tract dysfunctions, and our recent studies exploring "pro-micturition" and "anti-micturition" brain molecules related to stress responses. Based on evidence from these studies, we discuss the future directions of central neurourological research investigating how stress exposure-induced changes at peripheral and central levels affect urinary function and lower urinary tract dysfunctions. Brain molecules that we explored might be entry points into dissecting the stress-mediated process for modulating micturition.

Adverse Childhood Experiences in Women With Overactive Bladder or Interstitial Cystitis/Bladder Pain Syndrome

OBJECTIVE

The aim of the study was to compare the prevalence of adverse childhood experiences (ACEs) in women with overactive bladder (OAB) or interstitial cystitis/bladder pain syndrome (IC/BPS) to age-matched controls.

METHODS

This case-control study compared numbers and types of ACEs in women with OAB or IC/BPS compared with controls based on the Center for Disease Control's Behavioral Risk Factor Surveillance System ACE Module. Participants completed demographic forms, condition-specific symptom questionnaires, and the ACE Module (11 questions summarizing traumatic exposures occurring before the age of 18 years). Cases and controls were compared using χ2 and t tests, significance level P < 0.05.

RESULTS

Three hundred twenty-two women were enrolled from April 2018 to March 2019; OAB = 91 cases and 91 controls, IC/BPS = 70 cases and 70 controls. Overactive bladder group's mean age was 56 ± 13 years, and IC/BPS was 46 ± 13 years. Compared with controls, OAB and IC/BPS cases differed in race/ethnicity and education (P < 0.02), history of substance abuse (P ≤ 0.03), and median numbers of ACEs (OAB 3, controls 1; IC/BPS 4, controls 2, P < 0.01). Cases had increased odds of having 4 or more ACEs, a parameter known to be associated with poor health and longevity, and increased greater than 2-fold in OAB and greater than 7-fold in IC/BPS. Interstitial cystitis/bladder pain syndrome cases had notably increased odds of exposure to abuse (physical/emotional/sexual) and witnessed domestic violence (all P < 0.01).

CONCLUSIONS

Overactive bladder and IC/BPS cases reported increased ACE exposures; more than one-third of OAB and more than IC/BPS cases reported 4 or more ACES, a threshold associated with poor health outcomes. Recognition of increased childhood adversity in OAB and IC/BPS has important treatment and health implications.

The Role of Trauma and Mental Health in the Treatment of Chronic Pelvic Pain: A Systematic Review of the Intervention Literature

Chronic pelvic pain (CPP) is a widespread health issue with unclear etiology that has been linked to a history of trauma among women. This condition is known to be highly comorbid with, and potentially exacerbated by psychiatric conditions, as well as other gynecological concerns and functional pain syndromes. Many comorbid conditions are also related to a history of trauma, and cases of CPP with comorbidity are known to be resistant to treatment. While the prevalence of a traumatic history among females with CPP has been established, less is known about how the role of trauma is addressed in the intervention literature. The purpose of this systematic review was to explore how the role of trauma, and to a lesser extent, mental health, is addressed in modern intervention studies for females with CPP. All qualitative and quantitative studies providing primary or secondary results of an intervention for females with CPP published between January 1998 and May 2018 were included and coded independently by two reviewers. Twenty-eight articles met inclusion criteria. Of these, none focused exclusively on patients with a history of trauma; one study implicitly focused on trauma-specific symptoms as an outcome, while two studies screened patients for a history of trauma. Of the 10 studies with a focus on mental health, only three simultaneously addressed trauma. To address this gap in the literature, future studies can prioritize intervention designs that place emphasis on the role of trauma in regard to patient characteristics and outcome variables.

Adverse childhood experience and adult persistent pain and disability: protocol for a systematic review and meta-analysis

BACKGROUND

A growing body of research highlights the pervasive harms of adverse childhood experiences (ACEs) on health throughout the life-course. However, findings from prior reviews and recent longitudinal studies investigating the association between types of ACEs and persistent pain have yielded inconsistent findings in the strength and direction of associations. The purpose of this review is to appraise and summarize evidence on the relationship between ACEs and persistent pain and disability outcomes in adulthood. The specific aims are (1) to determine whether there is a relationship between exposure to ACE and persistent pain and disability in adults and (2) to determine whether unique and cumulative ACEs exposures (number and type) increase the risk of developing persistent pain and disability in adulthood.

METHOD

A systematic review and meta-analysis of observational studies will be conducted. Our eligibility criteria are defined following a PECOS approach: population, adults with persistent (≥ 3 months) musculoskeletal and somatoform painful disorders exposed to single or cumulative direct ACEs alone (i.e., physical, sexual, emotional abuse or neglect) or in combination to indirect types of ACE (e.g., parental death, exposure to domestic violence) in the first 18 years of life; comparators, unexposed individuals; outcomes, measurements for persistent pain (≥ 3 months) and disability using discrete and/or continuous measures; and settings, general population, primary care. A comprehensive search of MEDLINE (Ovid) and nine other pertinent databases was conducted from inception to 29 August 2019 using a combination of key words and MeSh terms (the search will be updated prior to conducting the analyses). Pairs of reviewers will independently screen records and full text articles, and a third reviewer will be consulted in cases of disagreement. Data will be extracted using Endnote and Covidence and a meta-analysis will be conducted using Review Manager (RevMan) Version 5.3. The Scottish Intercollegiate Guidelines Network (SIGN) and the Joanna Briggs Institute (JBI) checklists will be used to assess the quality of the included studies. If heterogeneity is high, the findings will be presented in narrative form.

DISCUSSION

The present review will help consolidate knowledge on persistent pain and disability by evaluating whether frequency and type of adverse childhood experiences produces the most harm. Findings may help inform practitioners and policy-makers who endeavor to prevent and/or mitigate the consequences of ACEs and promote healthy development and well-being of children, youth, and families.

The association between exposure to childhood maltreatment and the subsequent development of functional somatic and visceral pain syndromes

BACKGROUND

Childhood maltreatment is a global public health issue linked to a vast mortality and morbidity burden. This study builds on current literature to explore the risk of developing central sensitivity syndromes (CSS) (consisting of somatic and visceral pain syndromes) subsequent to childhood maltreatment exposure.

METHODS

A retrospective population based open cohort study using the UK primary care database, 'The Health Improvement Network,' between 1st January 1995-31st December 2018. 80,657 adult patients who had experienced childhood maltreatment or maltreatment related concerns (exposed patients) were matched to 161,314 unexposed patients by age and sex. Outcomes of interest were the development of CSS: either somatic (Fibromyalgia, chronic fatigue syndrome, temporomandibular joint disorder, chronic lower back pain, chronic headache, myofascial pain syndrome and restless leg syndrome) or visceral (Interstitial cystitis, vulvodynia, chronic prostatitis and irritable bowel syndrome) in nature. Effect sizes are presented as adjusted incidence rate ratios (aIRR) with confidence intervals (CI). Models were adjusted for the following covariates at cohort entry: age, sex, deprivation, anxiety, depression and serious mental ill health.

RESULTS

The average age at cohort entry was 23.4 years and the median follow was 2.2 years. There was an increased risk of developing fibromyalgia (aIRR 2.06; 95% CI 1.71-2.48), chronic fatigue syndrome (1.47; 1.08-2.00), chronic lower back pain (1.99; 1.68-2.35), restless leg syndrome (1.82; 1.41-2.35) and irritable bowel syndrome (1.15; 1.08-1.22) when compared to the unexposed group, whereas no statistical association was seen with the development of temporomandibular joint disorder (1.00; 0.88-1.13), chronic headache (1.04; 0.59-1.86), interstitial cystitis (1.19; 0.51-2.74), vulvodynia (0.65; 0.34-1.26), chronic prostatitis (0.34; 0.07-1.77) and myofascial pain syndrome (0.88; 0.36-2.14). Outcome numbers were low, most likely, due to the rarity of visceral conditions (aside from irritable bowel syndrome). The association between a history of childhood maltreatment and CSS were mainly observed in somatic CSS.

INTERPRETATION

The debilitating effects of CSS carry a substantial physical, psychological and economic burden to both the individuals who are diagnosed with them and the health services who serve them. Primary prevention approaches targeting childhood maltreatment as well as secondary preventative approaches should be considered to minimise the associated burden of CSS.

"The Overactive Pelvic Floor (OPF) and Sexual Dysfunction" Part 1: Pathophysiology of OPF and Its Impact on the Sexual Response

INTRODUCTION

Overactive pelvic floor (OPF) muscles are defined as muscles that do not relax, or may even contract, when relaxation is needed, for example, during micturition or defecation. Conditions associated with OPF are multifactorial and include multiple possible etiologies and symptom complexes. The complex interplay between biological and psychosocial elements can lead to the persistence of OPF symptoms along with psychological and emotional distress.

OBJECTIVES

(1) To review and contextualize, from a pathophysiologic perspective, the evidence for OPF, (2) to provide an overview of common clinical presentations and comorbidities of OPF, and (3) to discuss the effect of OPF on sexual function in men and women.

METHODS

Review of the updated literature on the pathophysiology of OPF was carried out. OPF-associated conditions were overviewed, with special emphasis on the impact on sexual function in men and women.

RESULTS

Individuals with suspected OPF often present with a combination of gastrointestinal, gynecological, musculoskeletal, sexual, and urological comorbidities, mostly accompanied by psychoemotional distress. In both women and men, sexual function is significantly impaired by OPF and genitopelvic pain penetration disorders are often the primary manifestation of this condition. Women with OPF report less sexual desire, arousal, and satisfaction; more difficulty reaching orgasm; lower frequencies of intercourse; more negative attitudes toward sexuality; and more sexual distress than women without sexual pain. The most frequently reported sexual dysfunctions in men with OPF include erectile dysfunction, premature ejaculation, and ejaculatory pain.

CONCLUSION

The complex pathophysiology of OPF involving multisystemic comorbidities and psychosocial factors emphasize the importance of a biopsychosocial assessment for guiding effective and personalized management.

Adverse Childhood Experiences and Symptoms of Urologic Chronic Pelvic Pain Syndrome: A Multidisciplinary Approach to the Study of Chronic Pelvic Pain Research Network Study

Background

Adverse Childhood Experiences (ACEs) such as sexual and physical violence, serious illness, and bereavement have been linked to number of chronic pain conditions in adulthood, and specifically to urologic chronic pelvic pain syndrome (UCPPS).

Purpose

We sought to characterize the prevalence of ACEs in UCPPS using a large well-characterized cohort in comparison with a group of healthy controls. We also sought to determine the association of ACE severity with psychological factors known to impact pain and to determine whether ACEs are associated with patterns of improvement or worsening of symptom over a year of naturalistic observation.

Methods

For longitudinal analyses we used functional clusters identifying broad classes of (a) improved, (b) worsened, and (c) stable groups for genitourinary pain and urinary symptoms. We employed a mediation/path analysis framework to determine whether ACEs influenced 1 year outcomes directly, or indirectly through worse perceptions of physical well-being.

Results

ACE severity was elevated in UCPPS (n = 421) participants compared with healthy controls (n = 414; p < .001), and was most strongly associated with factors associated with complex chronic pain, including more diffuse pain, comorbid functional symptoms/syndromes, and worse perceived physical well-being (all p < .001). Finally, worse physical well-being mediated the relationship between ACE severity and less likelihood of painful symptom improvement (OR = .871, p = .007)) and a greater likelihood of painful symptom worsening (OR = 1.249, p = .003) at 1 year.

Conclusions

These results confirm the association between ACEs and UCPPS symptoms, and suggest potential targets for therapeutic interventions in UCPPS.

Potential Mechanisms Underlying Centralized Pain and Emerging Therapeutic Interventions

Centralized pain syndromes are associated with changes within the central nervous system that amplify peripheral input and/or generate the perception of pain in the absence of a noxious stimulus. Examples of idiopathic functional disorders that are often categorized as centralized pain syndromes include fibromyalgia, chronic pelvic pain syndromes, migraine, and temporomandibular disorder. Patients often suffer from widespread pain, associated with more than one specific syndrome, and report fatigue, mood and sleep disturbances, and poor quality of life. The high degree of symptom comorbidity and a lack of definitive underlying etiology make these syndromes notoriously difficult to treat. The main purpose of this review article is to discuss potential mechanisms of centrally-driven pain amplification and how they may contribute to increased comorbidity, poorer pain outcomes, and decreased quality of life in patients diagnosed with centralized pain syndromes, as well as discuss emerging non-pharmacological therapies that improve symptomology associated with these syndromes. Abnormal regulation and output of the hypothalamic-pituitary-adrenal (HPA) axis is commonly associated with centralized pain disorders. The HPA axis is the primary stress response system and its activation results in downstream production of cortisol and a dampening of the immune response. Patients with centralized pain syndromes often present with hyper- or hypocortisolism and evidence of altered downstream signaling from the HPA axis including increased Mast cell (MC) infiltration and activation, which can lead to sensitization of nearby nociceptive afferents. Increased peripheral input via nociceptor activation can lead to “hyperalgesic priming” and/or “wind-up” and eventually to central sensitization through long term potentiation in the central nervous system. Other evidence of central modifications has been observed through brain imaging studies of functional connectivity and magnetic resonance spectroscopy and are shown to contribute to the widespreadness of pain and poor mood in patients with fibromyalgia and chronic urological pain. Non-pharmacological therapeutics, including exercise and cognitive behavioral therapy (CBT), have shown great promise in treating symptoms of centralized pain.

The Influence of Early Life Experience on Visceral Pain

Pain is the most reported and troublesome symptom of nearly all functional disorders affecting the genitourinary and gastrointestinal organs. Patients with irritable bowel syndrome (IBS), interstitial cystitis/painful bladder syndrome (IC/PBS), vulvodynia, and/or chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS; collectively termed chronic pelvic pain syndromes) report pain severe enough to impact quality of life and often suffer from symptoms of or are diagnosed with more than one of these syndromes. This increased comorbidity between chronic pelvic pain syndromes, and with pain disorders of disparate body regions, as well as with mood disorders, can be influenced by disruptions in the hypothalamic-pituitary-adrenal (HPA) axis, which regulates the response to stress and influences the perception of pain. Experiencing trauma, neglect, or abuse in early life can permanently affect the functioning of the HPA axis. As such, a significant proportion of patients suffering from comorbid chronic pelvic pain syndromes report a history of early life stress or trauma. Here we will report on how these early life experiences influence chronic pelvic pain in patients. We will also discuss various rodent models that have been developed to study this phenomenon to understand the mechanisms underlying HPA axis dysfunction, as well as potential underlying mechanisms connecting these syndromes to one another.

Functional urological disorders: a sensitized defence response in the bladder-gut-brain axis

Functional urological and gastrointestinal disorders are interrelated and characterized by a chronic course and considerable treatment resistance. Urological disorders associated with a sizeable functional effect include overactive bladder (OAB), interstitial cystitis/bladder pain syndrome (IC/BPS), and chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS). Poor treatment outcomes might be attributable to untreated underlying psychological and psychiatric disorders, as the co-occurrence of functional urological and gastrointestinal disorders with mood and anxiety disorders is common. The hypothetical bladder-gut-brain axis (BGBA) is a useful framework under which this interaction can be studied, suggesting that functional disorders represent a sensitized response to earlier threats such as childhood adversity or previous traumatic events, resulting in perceived emotional and bodily distress - the symptoms of functional disorders. Psychological and physical stress pathways might contribute to such alarm falsification, and neuroticism could be a risk factor for the co-occurrence of functional disorders and affective conditions. Additionally, physical threat - either from external sources or internal sources such as infection - might contribute to alarm falsification by influencing body-brain crosstalk on homeostasis and, therefore, affecting mood, cognition, and behaviour. Multidisciplinary research and an integrated care approach is, therefore, required to further elucidate and remediate functional urological and gastrointestinal polymorphic phenotypes.

Urinary bladder hypersensitivity and dysfunction in female mice following early life and adult stress

Early adverse events have been shown to increase the incidence of interstitial cystitis/painful bladder syndrome in adulthood. Despite high clinical relevance and reports of stress-related symptom exacerbation, animal models investigating the contribution of early life stress to female urological pain are lacking. We examined the impact of neonatal maternal separation (NMS) on bladder sensitivity and visceral neuroimmune status both prior-to, and following, water avoidance stress (WAS) in adult female mice. The visceromotor response to urinary bladder distension was increased at baseline and 8d post-WAS in NMS mice, while colorectal sensitivity was transiently increased 1d post-WAS only in naïve mice. Bladder micturition rate and output, but not fecal output, were also significantly increased following WAS in NMS mice. Changes in gene expression involved in regulating the stress response system were observed at baseline and following WAS in NMS mice, and WAS reduced serum corticosterone levels. Cytokine and growth factor mRNA levels in the bladder, and to a lesser extent in the colon, were significantly impacted by NMS and WAS. Peripheral mRNA levels of stress-responsive receptors were differentially influenced by early life and adult stress in bladder, but not colon, of naïve and NMS mice. Histological evidence of mast cell degranulation was increased in NMS bladder, while protein levels of protease activated receptor 2 (PAR2) and transient receptor potential ankyrin 1 (TRPA1) were increased by WAS. Together, this study provides new insight into mechanisms contributing to stress associated symptom onset or exacerbation in patients exposed to early life stress.

Urologic symptoms and functional neurologic disorders

The term functional urologic disorders covers a wide range of conditions related broadly to altered function rather than structure of the lower urinary tract, mainly of impaired urine voiding or storage. Confusingly, for a neurologic readership, these disorders of function may often be due to a urologic, gynecologic, or neurologic cause. However, there is a subset of functional urologic disorders where the cause remains uncertain and, in this chapter, we describe the clinical features of these disorders in turn: psychogenic urinary retention; Fowler's syndrome; paruresis (shy-bladder syndrome); dysfunctional voiding; idiopathic overactive bladder, and interstitial cystitis/bladder pain syndrome. Some of these overlap in terms of symptoms, but have become historically separated. Psychogenic urinary retention in particular has now largely been abandoned as a concept, in part because of the finding of specific urethral electromyogram findings in patients with this symptom now described as having Fowler's syndrome, and their successful treatment with sacral neurostimulation. In this chapter we review the poorly researched interface between these "idiopathic" functional urologic disorders and other functional disorders (e.g., irritable-bowel syndrome, fibromyalgia) as well as specifically functional neurologic disorders. We conclude that there may be a relationship and overlap between them and that this requires further research, especially in those idiopathic functional urologic disorders which involve disorders of the urethral sphincter (i.e., voluntary muscle).

Assessment of Perigenital Sensitivity and Prostatic Mast Cell Activation in a Mouse Model of Neonatal Maternal Separation

Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) has a lifetime prevalence of 14% and is the most common urological diagnosis for men under the age of 50, yet it is the least understood and studied chronic pelvic pain disorder. A significant subset of patients with chronic pelvic pain report having experienced early life stress or abuse, which can markedly affect the functioning and regulation of the hypothalamic-pituitary-adrenal (HPA) axis. Mast cell activation, which has been shown to be increased in both urine and expressed prostatic secretions of CP/CPPS patients, is partially regulated by downstream activation of the HPA axis. Neonatal maternal separation (NMS) has been used for over two decades to study the outcomes of early life stress in rodent models, including changes in the HPA axis and visceral sensitivity. Here we provide a detailed protocol for using NMS as a preclinical model of CP/CPPS in male C57BL/6 mice. We describe the methodology for performing NMS, assessing perigenital mechanical allodynia, and histological evidence of mast cell activation. We also provide evidence that early psychological stress can have long-lasting effects on the male urogenital system in mice.

Urgency and pain in patients with overactive bladder and bladder pain syndrome. What are the differences?

BACKGROUND

The Overactive Bladder Syndrome (OAB) and the Bladder Pain Syndrome/Interstitial Cystitis (BPS/IC) are different urological conditions sharing 'urgency' as a common symptom. The aim of this review is to address our existing knowledge and establish how these symptoms are interrelated and to determine whether or not there is a common link between both symptoms complexes that help to distinguish one from the other.

METHODS

Pubmed was used to obtain references for this non-systematic review aiming to discuss differences between OAB and BPS/IC. Guidelines of several professional associations and discussions based on expert opinion from the authors were implemented.

RESULTS

Whilst in BPS the hallmark symptom is pain on bladder filling, urgency is the defining symptom of OAB. Whilst it is likely that the pain in BPS/IC arises from local inflammation in the bladder wall, the nature of urgency as a symptom, its origin, and the relationship between urgency and pain, as well as the different afferent mechanisms associated with the genesis of these sensory symptoms, remains unknown. Although the aetiology of both OAB and PBS/IC is unclear, the influence of environmental factors has been suggested. Both are chronic conditions with very variable symptom resolution and response to therapy. The relationship with voiding dysfunction, gynaecological causes of chronic pelvic pain or the possible alteration of the hypothalamic-pituitary-adrenal axis and psychological disorders has not been established. Inflammation has been suggested as the common link between OAB and BPS/IC.

CONCLUSIONS

OAB and BPS/IC are different symptoms complexes that share urgency as a common symptom. None of them have a specific symptom although pain on bladder filling is the hallmark symptom in BPS/IC. Bladder pain with urgency should be a trigger for referral to the provider with appropriate knowledge and expertise in this disease state, whereas the management of OAB should be part of normal routine care in the community.

Vaginal hypersensitivity and hypothalamic-pituitary-adrenal axis dysfunction as a result of neonatal maternal separation in female mice

Early life stress can permanently alter functioning of the hypothalamic-pituitary-adrenal (HPA) axis, which regulates the stress response and influences the perception of pain. Chronic pelvic pain patients commonly report having experienced childhood neglect or abuse, which increases the likelihood of presenting with comorbid chronic pain and/or mood disorders. Animal models of neonatal stress commonly display enhanced anxiety-like behaviors, colorectal hypersensitivity, and disruption of proper neuro-immune interactions in adulthood. Here, we tested the hypothesis that early life stress impacts vaginal sensitivity by exposing mice to neonatal maternal separation (NMS) for 3h/day during the first two (NMS14) or three (NMS21) postnatal weeks. As adults, female mice underwent vaginal balloon distension (VBD), which was also considered an acute stress. Before or after VBD, mice were assessed for anxiety-like behavior, hindpaw sensitivity, and changes in gene and protein expression related to HPA axis function and regulation. NMS21 mice displayed significantly increased vaginal sensitivity compared to naïve mice, as well as significantly reduced anxiety-like behavior at baseline, which was heightened following VBD. NMS21 mice exhibited significant thermal and mechanical hindpaw hypersensitivity at baseline and following VBD. NMS14 mice displayed no change in anxiety-like behavior and only exhibited significantly increased hindpaw mechanical and thermal sensitivity following VBD. Centrally, a significant decrease in negative regulation of the HPA axis was observed in the hypothalamus and hippocampus of NMS21 mice. Peripherally, NMS and VBD affected the expression of inflammatory mediators in the vagina and bladder. Corticotropin-releasing factor (CRF) receptor and transient receptor potential (TRP) channel protein expression was also significantly, and differentially, affected in vagina, bladder, and colon by both NMS and VBD. Together these data indicate that NMS affects both central and peripheral aspects of the HPA axis, which may drive changes in vaginal sensitivity and the development of comorbid chronic pain and mood disorders.

[The care situation of patients with interstitial cystitis in Germany: results of a survey of 270 patients]

BACKGROUND

Using a comprehensive questionnaire the care situation of 270 patients with interstitial cystitis (IC) and bladder pain syndrome in Germany was recorded. Despite comprehensive literature on IC (62,000 citations in PubMed) almost nothing is known of the everyday care and quality of patient care in Germany.

RESULTS

In total 94% of the patients were women and 6% men, the average age of women was 53.5 years and that of men 67 years and 47.77% of the patients felt that they were well or very well informed about the disease whereby the internet was the source of information in many cases. The exchange of information among patients will increase further through social networks. The diagnosis of IC was made most frequently (62.22%) by biopsy and histological examination followed by urodynamics, potassium test, hydrodistension and cystoscopy. The average duration of the diagnosis was 9 years, 46.67% of the patients consulted a doctor more than 20 times before the diagnosis was made and 51.84% had to pass water more than 14 times per day. Frequency, nocturia and pain were the leading symptoms and 25% of the patients complained of urge incontinence. Among oral medications, analgesics were taken most frequently (61.7%) followed by pentosan polysulphate, antidepressants, antiepileptic drugs, antispasmodics and remedies for urinary urgency. In the self-assessment of the success of treatment with oral medications (helped very well and well), pentosan polysulphate, analgesics, antidepressants and antiepileptic drugs were considered to be the best. Medications that restore the glucosamine lining of the bladder were used predominantly for instillation into the bladder included hyaluronic acid, chondroitin sulphate and a combination of both and pentosan polysulphate. In the self-assessment of the success of treatment with instillation therapy (helped very well or well) the order was: chondroitin sulphate (62.69%), hyaluronic acid (55.77%), a combination of both (53.66%) and pentosan polysulphate (46.30%). The electromotive drug administration (EMDA) procedure with the use of direct current to introduce medications into the bladder wall was mentioned surprisingly often, namely, in 119 patients. In the self-assessment success (helped very well or well) was considered the best for intravesical procedures with 61.34%.

CONCLUSIONS

Compared with all drug procedures instillation of medications into the bladder was mentioned 368 times and was assessed by the patients as having helped very well and noticeably by 53.53%, followed by special invasive procedures at 50.56%/271 mentions, alternative therapies at 41.11%/287 mentions and oral medication at 39.75%/1,024 mentions. Hyaluronic acid and chondroitin sulphate products, the combination of both and pentosan polysulphate (oral and intravesical) are not reimbursed by the statutory health insurance. Over 40% of patients treated with these therefore discontinued the treatment for reasons of cost.

The sexual abuse of female children in Hungary: 20 years' experience

INTRODUCTION

The purpose of this study is to describe the characteristics of female children who experience sexual abuse and explore common features that may assist in developing prevention strategies.

MATERIALS AND METHODS

Between 1990 and 2010, 266 girls under the age of 18 years, suspected of being sexually abused, visited the Department of Adolescent Gynecology. We retrospectively collected data illustrating the features of all cases. Seventy-eight percent of the victims were primary school students, and 45% of them were between 11 and 14 years of age.

RESULTS

The perpetrator knew the victim in 67% of the cases and was a stranger in 33%. Seventy-five (28%) perpetrators were members of the victims' families. In 14% of cases, the perpetrator was the victim's father and in 9% her stepfather. The abuse had occurred on multiple occasions in 29% of the cases. The occurrence rate of abuse was highest in the summer season (54%). As much as 63% of children experienced vaginal penetration, while 37% experienced a variety of sexual contact that did not involve penetration. Eighty-five victims were physically injured, and in 40 cases the presence of sperm was confirmed in vulvo-vaginal smears. A high proportion of female child sexual abuse takes place within the family and is revealed only after multiple episodes. The true prevalence of sexual abuse is being appreciated now that Hungarian law and society have recognized this societal problem.

CONCLUSION

Prevention requires a systematic and lifelong approach to educating children about personal space and privacy and is the responsibility of parents and professionals.

Minimum 6-year outcomes for interstitial cystitis treated with sacral neuromodulation

INTRODUCTION AND HYPOTHESIS

Interstitial cystitis is a multifaceted medical condition consisting of pelvic pain, urgency, and frequency. Can sacral neuromodulation be successfully utilized for the medium term of ≥ 6 years in interstitial cystitis patients for whom standard drug therapies have failed?

METHODS

In our observational, retrospective, case-controlled review (January 2002-March 2004), we sought to discern whether neuromodulation could be successfully implemented with acceptable morbidity rates in interstitial cystitis patients. Thirty-four female patients underwent stage 1 and 2 InterStim placements under a general anesthetic. Simple means and medians were analyzed.

RESULTS

Mean pre-op/post-op pelvic pain and urgency/frequency scores were 21.61 ± 8.6/9.22 ± 6.6 (p < 0.01), and mean pre-op/post-op visual analog pain scale (VAPS) were 6.5 ± 2.9/2.4 ± 1.1 (p < 0.01). Median age was 41 ± 14.8 years with a mean follow-up of 86 ± 9.8 months.

CONCLUSIONS

With a minimum 6-year follow-up we determined that sacral neuromodulation provides adequate improvement for the symptoms of recalcitrant interstitial cystitis.
