"We the BE": An educational mobile health application for children and families affected by bladder exstrophy-epispadias-cloacal exstrophy complex.

GOALS: Despite the proliferation of over 45 000 smartphone mobile health applications (MHAs), as far as we know, there is no MHA for those living with rare diseases such as Bladder Exstrophy-Epispadias-Cloacal Exstrophy complex (BEEC). We hypothesized that an MHA could provide similar "on-demand" information and connectivity within health communities for patients with BEEC as they do for more common diseases. Thus, our primary goal was to create an MHA for patients and families affected by BEEC to provide them with important information about the condition and a format for them to connect with other affected patients and families. A secondary goal was to develop an adaptable MHA template for other rare diseases in the future. METHODS: We began our app development by examining existing common-disease MHAs for thematic structure. We conducted an extensive literature search of PubMed and Google scholar for MHA development and existing MHAs related to BEEC, utilizing these search terms: mobile health applications, rare diseases, bladder exstrophy, and online health communities. Our app development team began with our clinical multidisciplinary team of pediatric urologists; a child psychiatrist; a patient/family mental health therapist; and a certified nurse practitioner. We hired a website engineer and a production team. All clinical members have extensive experience caring for children and families affected by BEEC. Additionally, clinical team members compiled lists of themes deemed relevant from these reviews and themes gleaned from their clinical experience that appear with some frequency or urgency and from the myriad of themes discussed within the literature for MHAs. RESULTS: We found no existing rare disease MHAs in the literature or our search of app stores online. However, we derived basic app categories from existing MHA formats and the thematic content of all sources reviewed. These categories aligned with the groupings of our lists of clinical themes. Thus, we could subsume diverse themes within a broad categorical format: for example, child development (as "Psychological Development" in the app) or various clinical care options (as "Treatment"). This app structure became nine sections, as shown in. This format allows diverse information to be retrieved efficiently from broader categories. This app is being offered to affected families, healthcare providers, and individuals unrelated to where care is offered. CONCLUSION: "We the BE" is the first MHA developed for a rare disease, BEEC. It has been published in a downloadable format for the general public at no cost. Further research is required to determine its efficacy for the BEEC community members; preliminary, unsolicited feedback from multiple users has been positive.

Exploring Factors Associated with Decisions about Feminizing Genitoplasty in Differences of Sex Development.

STUDY OBJECTIVE: Infants with genital development considered atypical for assigned female sex may undergo feminizing genitoplasty (clitoroplasty and/or vaginoplasty) in early life. We sought to identify factors associated with parent/caregiver decisions regarding genitoplasty for their children with genital virilization. DESIGN: Longitudinal, observational study SETTING: Twelve pediatric centers in the United States with multidisciplinary differences/disorders of sex development clinics, 2015-2020 PARTICIPANTS: Children under 2 years old with genital appearance atypical for female sex of rearing and their parents/caregivers INTERVENTIONS/OUTCOME MEASURES: Data on the child's diagnosis and anatomic characteristics before surgery were extracted from the medical record. Parents/caregivers completed questionnaires on psychosocial distress, experience of uncertainty, cosmetic appearance of their child's genitalia, and demographic characteristics. Urologists rated cosmetic appearance. For 58 patients from the study cohort with genital virilization being raised as girls or gender-neutral, we compared these data across 3 groups based on the child's subsequent surgical intervention: (i) no surgery (n = 5), (ii) vaginoplasty without clitoroplasty (V-only) (n = 15), and (iii) vaginoplasty and clitoroplasty (V+C) (n = 38). RESULTS: Fathers' and urologists' ratings of genital appearance were more favorable in the no-surgery group than in the V-only and V+C groups. Clitorophallic length was greater in the V+C group compared with the V-only group, with substantial overlap between groups. Mothers' depressive and anxious symptoms were lower in the no-surgery group compared with the V-only and V+C groups. CONCLUSIONS: Surgical decisions were associated with fathers' and urologists' ratings of genital appearance, the child's anatomic characteristics, and mothers' depressive and anxious symptoms. Further research on surgical decision-making is needed to inform counseling practices.

Stigma, Intrusiveness, and Distress in Parents of Children with a Disorder/Difference of Sex Development.

OBJECTIVE: The impact of parent-reported stigma due to their child's disorder/difference of sex development (DSD) on parent psychosocial adjustment is poorly understood. In other pediatric populations, perceived interference of medical conditions into daily activities (i.e., illness intrusiveness ) mediates the relationship of stigma to adjustment. This study assessed relationships between parent-focused and child-focused stigma → illness intrusiveness → depressive and anxious symptoms . Exploratory analyses sought to identify patient characteristics associated with stigma. METHOD: Caregivers (59 women and 43 men) of 63 children diagnosed with a DSD up to age 4 years completed measures of demographics, parent-focused and child-focused stigma, illness intrusiveness, and depressive and anxious symptoms. RESULTS: Increased parent-focused and child-focused stigma were associated with increased illness intrusiveness, which, in turn, was associated with increased depressive and anxious symptoms for parents nested within dyads. Among children with DSD family histories, parents reported greater child-focused stigma. CONCLUSION: Parents who experience DSD-related stigma report greater interference of their child's DSD into their daily activities, which is associated with poorer psychosocial adjustment. Findings support developing clinical interventions related to parents' perceptions of stigma and illness intrusiveness to improve parent adjustment.

Post-operative complications following masculinizing genitoplasty in moderate to severe genital atypia: results from a multicenter, observational prospective cohort study.

INTRODUCTION: Differences of sex development (DSD) are congenital conditions in which there is atypical chromosomal, gonadal and/or phenotypic sex. A phenotype of severe genital atypia in patients raised as male is a relatively rare occurrence and standards for management are lacking. Decision making for early surgical planning in these rare cases includes, but is not limited to, degree of atypia, location of testes, and presence of Mϋllerian remnants. In this study we describe surgical approaches and short-term outcomes for masculinizing genitoplasty in moderate to severe genital atypia in young patients raised male, for whom parents opted for early surgery. METHODS: This NIH-sponsored study is an ongoing, observational, multicenter investigation assessing medical, surgical and psychological outcomes in children and their parents affected by atypical genitalia due to DSD. Participants were prospectively enrolled from 12 children's hospitals across the United States that specialize in DSD care. Criteria for child enrollment were a Quigley score of 3-6 in those with a 46, XY or 45,X/46, XY chromosome complement, age <3 years with no previous genitoplasty; patients were included independent of whether genitoplasty was performed. Cosmesis was graded according to a 4-point Likert scale and complications per the Clavian-Dindo classification. RESULTS: Of the 31 participants, 30 underwent hypospadias repair and 1 patient did not undergo a genitoplasty procedure. The majority of participants (22) received a staged hypospadias repair. Seventeen complications were identified in 12 of the 31 children (41%) at 12 months of follow up. Glans dehiscence and urethrocutaneous fistula were the most common complications. Orchiopexy was performed in 14 (44%) and streak gonads were removed in 4 (13%) participants. Both parents and surgeons reported improved cosmesis after surgery when compared to baseline. CONCLUSION: Genitoplasty was chosen by parents for the majority of children eligible for study. No single surgical approach for masculinizing moderate to severe genital ambiguity in young patients with 46, XY or 45,X/46, XY DSD was adopted by all surgeons. Complications occurred in 41% of those who underwent genitoplasty for severe hypospadias. Overall, appearance of the genitals, as determined by parents and surgeons, improved following genitoplasty. Outcomes of early genitoplasty are needed to guide families when making decisions about such procedures for their young children.

Distress Trajectories for Parents of Children With DSD: A Growth Mixture Model.

OBJECTIVE: This study identifies trajectories of parent depressive symptoms after having a child born with genital atypia due to a disorder/difference of sex development (DSD) or congenital adrenal hyperplasia (CAH) and across the first year postgenitoplasty (for parents who opted for surgery) or postbaseline (for parents who elected against surgery for their child). Hypotheses for four trajectory classes were guided by parent distress patterns previously identified among other medical conditions. METHODS: Participants included 70 mothers and 50 fathers of 71 children diagnosed with a DSD or CAH with reported moderate to high genital atypia. Parents were recruited from 11 US DSD specialty clinics within 2 years of the child's birth and prior to genitoplasty. A growth mixture model (GMM) was conducted to identify classes of parent depressive symptoms over time. RESULTS: The best fitting model was a five-class linear GMM with freely estimated intercept variance. The classes identified were termed "Resilient," "Recovery," "Chronic," "Escalating," and "Elevated Partial Recovery." Four classes have previously been identified for other pediatric illnesses; however, a fifth class was also identified. The majority of parents were classified in the "Resilient" class (67.6%). CONCLUSIONS: This study provides new knowledge about the trajectories of depressive symptoms for parents of children with DSD. Future studies are needed to identify developmental, medical, or familial predictors of these trajectories.

Illness Uncertainty Longitudinally Predicts Distress Among Caregivers of Children Born With DSD.

OBJECTIVE: A subset of parents of children with disorders/differences of sex development (DSD) including ambiguous genitalia experience clinically elevated levels of anxious and depressive symptoms. Research indicates that uncertainty about their child's DSD is associated with parent psychosocial distress; however, previous studies have been cross-sectional or correlational in nature. The current study is the first to examine the longitudinal trajectory of the relationship between caregiver-perceived uncertainty about their child's DSD and caregiver anxious and depressive symptoms across the first 12 months following genital surgery in young children, or if surgery was not performed, the first 12 months following study entry. METHODS: One hundred and thirteen caregivers (Mage = 32.12; 57.5% mothers; 72.6% Caucasian) of children (N = 70; Mage = 9.81 months; 65.7% female) with DSD were recruited from 12 DSD specialty clinics in the United States. Caregivers completed psychosocial measures at baseline, 6 and 12 months following genitoplasty, or study entry if parents elected not to have surgery for their child. RESULTS: Caregiver illness uncertainty and both anxious and depressive symptoms were highest at baseline and decreased over time (ps < .05). Caregiver illness uncertainty predicted symptoms of anxious and depressive symptoms across all time points (ps < .05). CONCLUSIONS: Caregivers' perceptions of uncertainty about their child's DSD are highest soon after diagnosis, and uncertainty continues to predict both anxious and depressive symptoms across time. Thus, the initial diagnostic period is a critical time for psychological assessment and intervention, with parent illness uncertainty being an important clinical target.

Post-operative complications following feminizing genitoplasty in moderate to severe genital atypia: Results from a multicenter, observational prospective cohort study.

Disorders/differences of sex development (DSD) are congenital conditions in which there is atypical chromosomal, gonadal and/or phenotypic sex. While there remains controversy around the traditionally binary concept of sex, most patients with DSD are reared either male or female depending on their genetic sex, gonadal sex, genital phenotype and status of their internal genital tract. This study uses prospective data from 12 institutions across the United States that specialize in DSD care. We focused on patients raised female. Eligible patients had moderate to severe genital atypia (defined as Prader score >2), were ≤2 years of age at entry, and had no prior genitoplasty. The aim of this study is to describe early post operative complications for young patients undergoing modern approaches to feminizing genitoplasty. Of the 91 participants in the cohort, 57 (62%) were reared female. The majority had congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency (n = 52), 1 had ovo-testicular syndrome, 2 had mixed gonadal dysgenesis and 2 had partial androgen insensitivity syndrome (PAIS). Of the 50 participants who received early genitoplasty, 43 (86%) had follow-up at 6-12 months post-surgery. Thirty-two participants (64%) received a clitoroplasty, 31 (62%) partial urogenital mobilization and 4 (8%) total urogenital sinus mobilization. Eighteen percent (9/50) experienced post-surgical complications with 7 (14%) being rated as Clavien-Dindo grade III. Both parents and surgeons reported improved satisfaction with genital appearance of participants following surgery compared to baseline. This information on post-operative complications associated with contemporary approaches to feminizing genitoplasty performed in young children will help guide families when making decisions about whether or not to proceed with surgery for female patients with moderate to severe genital atypia.

Predictors of Psychosocial Distress in Parents of Young Children with Disorders of Sex Development.

PURPOSE: We evaluated demographic, financial and support predictors of distress for parents of young children with disorders of sex development including atypical genital development, and characterized early parental experiences. This work extends our previous findings to identify those parents at risk for distress. MATERIALS AND METHODS: Participants included mothers (76) and fathers (63) of a child (78) diagnosed with disorders of sex development characterized by moderate to severe genital atypia. Parents completed a demographic questionnaire, measures of anxious and depressive symptoms, quality of life, illness uncertainty and posttraumatic stress symptoms, and rated their satisfaction with the appearance of their child's genitalia. RESULTS: Depressive and posttraumatic stress symptoms of caregivers were comparable to standardized norms while levels of anxious symptoms were below norms. A subset of parents reported clinically elevated symptoms. Overall 26% of parents reported anxious symptoms, 24% reported depressive symptoms and 17% reported posttraumatic stress symptoms. Levels of illness uncertainty were lower than those of parents of children with other chronic illnesses. Differences by parent sex emerged, with mothers reporting greater distress. Lower income, increased medical care and travel expenses, and having no other children were related to increased psychosocial distress. CONCLUSIONS: Early psychosocial screening is recommended for parents of children with disorders of sex development. Clinicians should be aware that financial burden and lack of previous parenting experience are risk factors for distress.

Uncertainty and Posttraumatic Stress: Differences Between Mothers and Fathers of Infants with Disorders of Sex Development.

Parents of children with disorders of sex development (DSD) report significant psychological distress, including posttraumatic stress symptoms (PTSS), with mothers consistently reporting higher rates of psychological distress than fathers. However, psychological factors contributing to PTSS in both parents are not well understood. The present study sought to fill this gap in knowledge by examining PTSS and illness uncertainty, a known predictor of psychological distress, in parents of children recently diagnosed with DSD. Participants were 52 mothers (Mage = 32.55 years, SD = 5.08) and 41 fathers (Mage = 35.53 years, SD = 6.78) of 53 infants (Mage = 9.09 months, SD = 6.19) with DSD and associated atypical genital development. Participants were recruited as part of a larger, multisite study assessing parents' psychosocial response to their child's diagnosis of DSD. Parents completed measures of illness uncertainty and PTSS. Mothers reported significantly greater levels of PTSS, but not illness uncertainty, than fathers, and were more likely than fathers to report clinical levels of PTSS (21.2% compared to 7.3%). Hierarchical regression revealed that parent sex, undiagnosed or unclassified DSD status, and illness uncertainty were each associated with PTSS. The overall model accounted for 23.5% of the variance associated with PTSS. Interventions targeting illness uncertainty may be beneficial for parents of children with newly diagnosed DSD.

Free Tissue Transfer Penile Reconstruction.

Phalloplasty can be a challenging plastic surgery procedure associated with complications and unsatisfactory results. Phalloplasty has become an important procedure in the setting of trauma, partial or complete excision of the penis, and gender affirmation. Advances in microsurgery has expanded penile reconstruction through free tissue transfer techniques which include the radial forearm free flap, fibular osteocutaneous flap, anterolateral thigh flap, latissimus dorsi flap, scapular flap, and abdominal flaps. Each procedure has advantages and disadvantages; most of the procedures achieve adequate cosmetic results with high patient satisfaction. Most of the surgical complications are related to the reconstruction of the urethra or creating rigidity for intercourse. The main goals of reconstruction are to create a cosmetically appealing phallus with satisfactory sexual function.

Baseline Characteristics of Infants With Atypical Genital Development: Phenotypes, Diagnoses, and Sex of Rearing.

PURPOSE: Little is known about the phenotypes, diagnoses, and sex of rearing of infants with atypical genital development in the United States. As part of a multicenter study of these infants, we have provided a baseline report from US difference/disorder of sex development clinics describing the diagnoses, anatomic features, and sex of rearing. We also determined whether consensus guidelines are followed for sex designation in the United States. METHODS: Eligible participants had moderate-to-severe genital atypia, were aged <3 years, and had not undergone previous genitoplasty. Karyotype, genetic diagnosis, difference/disorder of sex development etiology, family history, and sex of rearing were collected. Standardized examinations were performed. RESULTS: Of 92 subjects, the karyotypes were 46,XX for 57%, 46,XY for 34%, and sex chromosome abnormality for 9%. The median age at the baseline evaluation was 8.8 months. Most 46,XX subjects (91%) had congenital adrenal hyperplasia (CAH) and most 46,XY subjects (65%) did not have a known diagnosis. Two individuals with CAH underwent a change in sex of rearing from male to female within 2 weeks of birth. The presence of a uterus and shorter phallic length were associated with female sex of rearing. The most common karyotype and diagnosis was 46,XX with CAH, followed by 46,XY with an unknown diagnosis. Phenotypically, atypical genitalia have been most commonly characterized by abnormal labioscrotal tissue, phallic length, and urethral meatus location. CONCLUSIONS: An increased phallic length was positively associated with rearing male. Among the US centers studied, sex designation followed the Consensus Statement recommendations. Further study is needed to determine whether this results in patient satisfaction.

Immunomodulatory response of layered small intestinal submucosa in a rat bladder regeneration model.

Based on the hypothesis that bioscaffold permeability is a major factor in determining the outcome of histologically complete and functional bladder regeneration, we evaluated regeneration processes of four-layer porcine small intestinal submucosa (SIS) construct; and compared results between rat bladders augmented with single-layer SIS bioscaffolds. Sprague-Dawley female rats were subjected to hemi-cystectomy followed by anastomosis of a patch of either single- or four-layer porcine SIS. Permeability was analyzed in situ using magnetic resonance imaging (MRI) at post-operative days 7 and 14. Bladder sections excised at days 7, 14, 28, and 56 post-operation Samples were assessed by H&E and Masson's trichrome stains. Urothelial differentiation was analyzed using cytokeratin AE1/AE3, and uroplakin III (UPIII). In addition, quantitative and qualitative evaluations of neutrophils, mast cells, eosinophils, and macrophages were performed using anti-myeloperoxidase, Alcian blue, Giemsa stain, and anti-CD68 staining methods, respectively. Four-layer SIS was consistently impermeable as evidenced by the absence of intravesical administered gadolinium with diethylenetriaminepentacetate (Gd-DTPA) contrast signal in peripheral regions of augmented bladders compared with single-layer SIS bioscaffold. Elevated and sustained eosinophil and neutrophil infiltrations were prominent in four-layered SIS-augmented bladders compared with single-layer SIS with comparable impermeability. Delayed but consistent urothelial regeneration and differentiation were observed in four-layer SIS-augmented bladders; and urothelial differentiation was observed at day 56 post-augmentation. In conclusion, four-layer SIS enacts an elevated inflammatory response along with extended urothelial regeneration. Four-layer SIS may activate a different but yet to be identified mechanism for inflammatory responses. © 2018 Wiley Periodicals, Inc. J Biomed Mater Res Part B: Appl Biomater 107B: 1960-1969, 2019.

Parent-Rated Severity of Illness and Anxiety among Caregivers of Children Born with a Disorder of Sex Development Including Ambiguous Genitalia.

BACKGROUND/AIMS: Parents of children born with disorders of sex development (DSD) often experience anxiety, but risk factors, including parental perception of the severity of their child's DSD, have not been examined. We hypothesized that severity of illness (SOI) ratings would relate to parental anxiety, and would be higher for parents of children with a potentially life-threatening DSD (e.g., 21-hydroxylase deficiency). METHODS: Eighty-nine parents (Mage = 33.0, 56.2% mothers) of 51 children (Mage in months = 8.7) with a DSD including ambiguous genitalia were recruited from 12 specialized DSD clinics. Parents completed questionnaires prior to genitoplasty, 6 months post-genitoplasty, and 12 months post-genitoplasty (if completed). Data were analyzed with linear mixed modeling. RESULTS: Parental anxiety decreased over time, χ2(1) = 10.14, p < 0.01. A positive relationship between SOI and anxiety was found, with SOI being a strong predictor of anxiety (b = 0.53, p < 0.01; χ2[1] = 5.33, p < 0.05). An SOI by time interaction indicated SOI had an increasing effect on anxiety over time, b = 0.06, p < 0.05; χ2(1) = 6.30, p < 0.05. There was no diagnosis by SOI interaction. CONCLUSION: Parental anxiety decreased over time, but those with higher SOI ratings reported greater initial anxiety followed by slower resolution over time. Underlying etiology of DSD had no effect on the relationship between SOI and anxiety.

Who, where, and why are patients lost to follow-up? A 20-year study of bladder exstrophy patients at a single institution.

INTRODUCTION: Individuals with bladder and cloacal exstrophy are at increased risk for kidney disease, renal failure, and bladder complications. Given the social implications and sensitive nature of the disease, these patients are also at risk for psychosocial problems. Lack of regular medical follow-up visits may pose serious risks to their long-term health status. The aim of this study is determine what factors place an affected individual at risk for limited long term follow up. MATERIALS AND METHODS: We identified all patients with bladder or cloacal exstrophy seen by the pediatric urology department at the Oklahoma University Health Sciences Center (OUHSC) between January 1996 and August 2016. Patient data included demographics, insurance coverage, distance from patient's home to the clinic, medical and surgical history, and the date of their last clinic visit. Two groups for comparison were (1) those that had been seen within the last 2 years, and (2) those that were counted as failing to maintain follow-up because 2 or more years had passed since their last clinic visit. These groups were compared using the Student t-test, the chi-square test, or the Fisher exact test and p < 0.05 was treated as significant for the purposes of discussion. RESULTS AND DISCUSSION: Ninety-one patients with bladder or cloacal exstrophy were seen by the pediatric urology department between January 1996 and August 2016. Of the 91 patients, 24 left the clinic for known reasons thus leaving 67 patients that were considered for analyses: 51 had been seen within the last 2 years while 16 were counted as lost to follow-up. These two groups (active and lost to follow-up) did not differ significantly for age at last clinic visit, distance between family's home and clinic, history of bladder reconstruction, sex, or insurance status. There was a significant difference between the two groups in the medical complexity of their condition. The group active in urological care had more patients with cloacal exstrophy and additional anomalies than the group lost to follow-up. CONCLUSIONS: Patients with bladder exstrophy and cloacal exstrophy are less likely to maintain annual follow-up visits with their urologist if they have a simpler diagnosis requiring fewer surgical interventions. For patients with exstrophy, regular clinic visits prioritizing education and psychosocial support may prevent hospitalizations, emergency interventions, and poor overall health outcomes. To maintain contact with the medical team and promote optimal health outcomes, a social worker or care coordinator/educator may play an integral part in addressing the unique needs of this population.

Reduced urothelial regeneration in rat bladders augmented with permeable porcine small intestinal submucosa assessed by magnetic resonance imaging.

Augmentation enterocystoplasty remains the gold standard surgical bladder reconstruction procedure to increase the capacity and compliance of dysfunctional bladders. Since the use of the patient's intestine has severe risks of complications, alternative biodegradable matrices have been explored. Porcine small intestinal submucosa (SIS) has gained immense interests in bladder reconstruction due to its favorable properties. However, trials have shown inconsistent regeneration with SIS, attributed to the heterogeneity in microstructures and mechanical properties. We hypothesize that uneven SIS permeability to urine is a factor responsible for the inconsistency. We measured permeability to urine in situ using a contrast enhanced-magnetic resonance imaging (MRI), and evaluated urothelium regeneration using immunohistochemical staining of urothelial cell markers in SIS-augmented rat bladders. Results showed significant differences in permeability among SIS-augmented rat bladders. Commercial SIS scaffolds were then categorized into nonleaky and leaky groups based on MRI results. Hematoxylin and eosin staining showed higher numbers of inflammatory cells in leaky SIS on day 14 relative to nonleaky SIS. In addition, trichrome staining showed major changes in the distribution of collagen on day 28 between SIS-augmented bladder groups. Furthermore, expressions of urothelium-associated markers (cytokeratins AE1/AE3, claudin 4, and uroplakin III) were completed in bladders augmented with nonleaky SIS, whereas limited urothelial differentiation was noticed in leaky SIS-augmented bladders at post-augmentative day 14. These results show that scaffold permeability to urine may be responsible for variations in regenerative capacity of porcine SIS. Applications of MRI technique will be helpful to understand a relationship between biomaterial property and regenerative capacity. © 2017 Wiley Periodicals, Inc.
