RESUMO

In newborns, it is an emergency to decide the appropriate sex for rearing and eventual prevention associated metabolic disturbances. The birth of a baby with ambiguous genitalia inevitably precipitates a crisis for the baby and its family. This retrospective analysis of hospital data was designed to determine the chromosomal and etiological diagnosis of children presented with suspected disorders of sex development (DSD) according to the newer DSD consensus document. We retrospectively analyzed the available medical records of all patients admitted into the inpatient departments of Dhaka Shishu (Children) Hospital, Dhaka, Bangladesh from January 2014 to December 2019, and all patients with the diagnosis of DSD in the hospital record were initially selected for the study. A total of 60 admitted cases with a disorder of sex development were classified according to the new DSD classification. 46XX DSD were 63.3% (n=38), 46XY DSD were 33.3% (n=20), sex chromosome DSD were 3.3% (n=2). Among 38 cases of 46XX DSD, the most common cause was congenital adrenal hyperplasia (97.0%, n=37), one was 46XX testicular DSD. However, among 46XY DSD cases, partial androgen insensitivity/5α-reductase deficiency (50.0%, n=10) was most common disorder. Other causes of 46XY DSD included congenital adrenal hyperplasia (20.0%, n=4), testosterone synthesis defect (20.0%, n=4), testicular regression syndrome (n=1) and persistent Mullerian duct syndrome (n=1). Sex chromosome disorders are mixed gonadal dysgenesis (n=1), chimeric ovotesticular DSD (n=1). In this study, 46XX DSD was the commonest of all, showing the predominance of congenital adrenal hyperplasia, especially salt-losing type. Early detection and prompt treatment may help reduce mortality and morbidity from these acute life-threatening conditions.

RESUMO

INTRODUCTION: The aim of the current work was to review the clinical profile, aetiological classification, as well as the management of Egyptian paediatric patients with disorders of sex development (DSD) presenting at a tertiary centre in Cairo. MATERIAL AND METHODS: The study was a cross-sectional observational study that included Egyptian patients who attended the Endocrinology clinic during a period of one year from January to December 2019. All patients with overt genital ambiguity aged from 0 to 18 years were recruited in the study. Diagnosis of DSD was based on clinical features and hormonal profile. RESULTS: Out of 100 patients, 71% had 46XY DSD, 24% had 46XX DSD, while sex chromosome DSD was identified in 5%. The median age of presentation was 12 months with 19% presented during infancy. The most common cause of 46XY DSD was due to either defect in androgen synthesis or action (40%) with the majority due to androgen insensitivity syndrome (28%). Most of the 46XX DSD (21/24) patients were diagnosed as classic congenital adrenal hyperplasia secondary to deficiency of 21 hydroxylase enzyme, with 90% being salt wasters. CONCLUSION: Our series revealed that 46XY DSD was the most frequent DSD aetiological diagnosis, with androgen insensitivity syndrome representing the commonest cause. CAH with classic salt wasting type was the second most common disorder. Management of children with DSD is challenging especially with lack of adequate resources. The crucial issues that stand against proper diagnosis and management are late presentation combined with economic constrains, and social and cultural issues.

RESUMO

Heterozygous mutations in the human SOX9 gene cause the skeletal malformation syndrome campomelic dysplasia which in 75% of 46, XY individuals is associated with male-to-female sex reversal. Although studies in homozygous Sox9 knockout mouse models confirmed that SOX9 is critical for testis development, mice heterozygous for the Sox9-null allele were reported to develop normal testes. This led to the belief that the SOX9 dosage requirement for testis differentiation is different between humans, which often require both alleles, and mice, in which one allele is sufficient. However, in prior studies, gonadal phenotypes in heterozygous Sox9 XY mice were assessed only by either gross morphology, histological staining or analyzed on a mixed genetic background. In this study, we conditionally inactivated Sox9 in somatic cells of developing gonads using the Nr5a1-Cre mouse line on a pure C57BL/6 genetic background. Section and whole-mount immunofluorescence for testicular and ovarian markers showed that XY Sox9 heterozygous gonads developed as ovotestes. Quantitative droplet digital PCR confirmed a 50% reduction of Sox9 mRNA as well as partial sex reversal shown by an upregulation of ovarian genes. Our data show that haploinsufficiency of Sox9 can perturb testis development in mice, suggesting that mice may provide a more accurate model of human disorders/differences of sex development than previously thought.

RESUMO

The increasing incidence of testicular dysgenesis syndrome-related conditions and overall decline in human fertility has been linked to the prevalence of oestrogenic endocrine disrupting chemicals (EDCs) in the environment. Ectopic activation of oestrogen signalling by EDCs in the gonad can impact testis and ovary function and development. Oestrogen is the critical driver of ovarian differentiation in non-mammalian vertebrates, and in its absence a testis will form. In contrast, oestrogen is not required for mammalian ovarian differentiation, but it is essential for its maintenance, illustrating it is necessary for reinforcing ovarian fate. Interestingly, exposure of the bi-potential gonad to exogenous oestrogen can cause XY sex reversal in marsupials and this is mediated by the cytoplasmic retention of the testis-determining factor SOX9 (sex-determining region Y box transcription factor 9). Oestrogen can similarly suppress SOX9 and activate ovarian genes in both humans and mice, demonstrating it plays an essential role in all mammals in mediating gonad somatic cell fate. Here, we review the molecular control of gonad differentiation and explore the mechanisms through which exogenous oestrogen can influence somatic cell fate to disrupt gonad development and function. Understanding these mechanisms is essential for defining the effects of oestrogenic EDCs on the developing gonads and ultimately their impacts on human reproductive health.

RESUMO

The gonads are unique among the body's organs in having a developmental choice: testis or ovary formation. Gonadal sex differentiation involves common progenitor cells that form either Sertoli and Leydig cells in the testis or granulosa and thecal cells in the ovary. Single-cell analysis is now shedding new light on how these cell lineages are specified and how they interact with the germline. Such studies are also providing new information on gonadal maturation, ageing and the somatic-germ cell niche. Furthermore, they have the potential to improve our understanding and diagnosis of Disorders/Differences of Sex Development (DSDs). DSDs occur when chromosomal, gonadal or anatomical sex are atypical. Despite major advances in recent years, most cases of DSD still cannot be explained at the molecular level. This presents a major pediatric concern. The emergence of single-cell genomics and transcriptomics now presents a novel avenue for DSD analysis, for both diagnosis and for understanding the molecular genetic etiology. Such -omics datasets have the potential to enhance our understanding of the cellular origins and pathogenesis of DSDs, as well as infertility and gonadal diseases such as cancer.

RESUMO

BACKGROUND: Disorders of sex development (DSD) are rare conditions. Although they are known to predispose to germ cell tumors (GCT), there is a paucity of information regarding the circumstances of DSD discovery. DESIGN/METHODS: All patients with DSD registered in two French pediatric GCT protocols (TGM95 and 13) were analyzed. RESULTS: Sixteen patients were identified among 276 ovarian, 160 testicular, and 24 mediastinal GCT. Eleven phenotypic females (median age 15 years) exhibited gonadal GCT, including 10 with a 46,XY karyotype and gonadal dysgenesis and one with 46XX,45X0 mosaicism. None had genital anomalies, seven had spontaneous pubertal changes, and one had spontaneous menarche. The tumors were bilateral in four cases. DSD was diagnosed after the GCT diagnosis in seven cases. The reasons for karyotyping were bilateral tumors (3), gonadoblastoma/streak gonad/absence of egg follicles (3), or systematic for GCT (1). The karyotyping was performed before the GCT diagnosis in four cases: for polymalformative syndrome (2) or primary amenorrhea (2). Four males (median age 14 years) exhibited mediastinal GCT (metastatic in two cases) indicative of Klinefelter syndrome, despite typical phenotypes in all cases. The remaining patient had severe hypospadias, leading to the discovery of 46,XY/45,X0 mosaicism before the diagnosis of testicular nonseminomatous GCT at 16 years of age. CONCLUSION: DSD are often uncovered at the time of GCT diagnosis (11/16 cases). This should prompt oncologists to rule out a DSD in patients with GCT, even in case of pubertal development. Earlier recognition of Klinefelter syndrome could potentially lead to GCT detection at an earlier stage.

RESUMO

Primary adrenal insufficiency (PAI) in children is mostly due to genetic defects. The understanding of the molecular genetics of the causes of adrenal insufficiency in the pediatric population has made significant progress during the last years. It has been shown that inherited PAI can lead to certain clinical manifestations and health problems in children beyond the adrenals. Organ dysfunctions associated with different forms of PAI in children include a wide range of organs such as gonads, brain, heart, bone, growth, bone marrow, kidney, skin, parathyroid, and thyroid. Diagnosing the correct genetic cause of PAI in children is therefore crucial to adequately control long-term treatment and follow-up in such patients.

RESUMO

RESUMEN Los trastornos del desarrollo sexual son estados congénitos en los cuales el desarrollo del sexo cromosómico, gonadal o anatómico es atípico. Por tratarse de un caso sumamente raro consideramos de interés su presentación. Se presenta adolescente masculino de 15 años, con antecedentes de genitales atípicos al nacer, desarrollo de baja talla y estigmas turnerianos, pubertad espontánea y normal. Los estudios genéticos determinaron como sexo cromosómico un mosaico 45,X/46,XY/47XYY, y sexo molecular varón. Se inscribió socialmente como varón, se le realizó cirugía de reconstrucción genital y utilizó tratamiento con hormona de crecimiento biosintética que mantiene actualmente. La evolución clínica ha sido favorable con adecuada integración social. Ante la presencia de genitales atípicos al nacer se necesita de un manejo multidisciplinario. El diagnóstico etiológico de los trastornos de la diferenciación sexual requiere de una alta pericia médica. Un tratamiento integral en estos pacientes les garantiza una buena calidad de vida(AU)


ABSTRACT Sexual development´s disorders are congenital states in which the development of the chromosomal, anatomic or gonadal sex is atypical. Since this is a very rare case, we consider it as of interests for presentation. It is presented a teenager, 15-years-old male, with a history of atypical genitalia at birth, development of short height and Turner's stigmas, and spontaneous and normal puberty. The genetic studies identified as chromosomal sex a mosaic 45,X/46,XY/47XYY and male as molecular sex. He was socially registered as a male, he had a genital reconstruction surgery and he was under treatment with biosynthetic growth hormone that he currently maintains. The clinical evolution has been favourable with adequate social integration. In the presence of atypical genitalia at birth, it is needed a multidisciplinary management. The etiological diagnosis of disorders of sexual differentiation requires a high level of medical expertise. A comprehensive treatment in these patients guarantees them a good quality of life(AU)

RESUMO

INTRODUCTION/BACKGROUND: The impact of having a child with atypical genitalia due to a life-threating chronic medical condition like congenital adrenal hyperplasia (CAH) is poorly understood. OBJECTIVE: The aim of the study was to determine parental stress and impact of CAH on parental decisions, including decisions regarding female genital restoration surgery (FGRS). STUDY DESIGN: The authors surveyed consecutive parents of girls with CAH ≤3 years presenting at a tertiary referral center for FGRS consultation (2016-2019). The survey was developed by three families of daughters with CAH and six clinicians. Nine potentially stressful past experiences were rated on a 6-point Likert scale ('not at all' to 'extremely' stressful). Overall parental stress and strain (broader negative consequences) were reported using validated instruments (Perceived Stress Scale and Caregiver Strain Questionnaire Short Form, respectively). Impact of CAH on past decisions about childcare, social interactions, and who changes diapers were also assessed. Non-parametric tests were used for analysis. RESULTS: Twenty-nine parents (median age: 32years) of 22 consecutive children participated (Prader 3/4/5: 59.1%/36.4%/4.5%). After the study, 20 girls (90.9%) underwent FGRS at a median age of 8 months. The most stressful experiences were having an adrenal crisis ('very much' stressful), waiting for the CAH diagnosis, and making sense of the diagnosis (both 'quite a bit') (Figure 1). Remaining issues were 'somewhat' stressful. Deciding whether to proceed with FGRS was ranked as the least stressful issue. Overall parental stress was similar to overall stress previously reported by spousal caregivers of stroke or heart failure survivors (P ≥ 0.15). Overall parental strain was similar to parents of adolescents receiving mental health counseling (P = 0.77). Congenital adrenal hyperplasia impacted decisions about babysitting, daycare, who changed diapers, and choosing a pediatrician (P ≤ 0.02), but did not impact parental social interactions (P ≥ 0.11). Diapers were typically changed by parents (100.0%) and grandmothers (50.0%). Parents anticipated that some individuals currently not allowed to change diapers would be allowed after FGRS: grandfathers (+18.2%), aunts/uncles (+27.3-32.8%), cousins (+18.2%), and family friends (+45.5%). DISCUSSION: The authors present the first assessment of parental stress with respect to different aspects of care of a daughter with CAH. Larger studies are required to determine if the parental stress associated with these experiences varies over time and how these stressors rank relative to each other through the child's development. CONCLUSION: Parents experience multiple stressors after having a daughter with CAH. Parental stress surrounding a decision about FGRS appears less severe than events pertaining to the diagnosis and medical management of CAH. Congenital adrenal hyperplasia impacts multiple parental decisions.

RESUMO

Objective: To explore the feasibility of gender assignment in 46,XY disorders of sex development (DSD) with severe undermasculinisation mainly based on molecular diagnosis. Methods: A retrospective study of 45 patients of 46, XY DSD with severe undermasculinisation were admitted between November 2015 and October 2018 at Children's Hospital, Zhejiang University School of Medicine. The initial social gender were all female, of whom the external genital manifestations were Prader 0 to 2; the degree of masculinity was scored using external masculinisation score (EMS); the position and development of the gonads were examined by ultrasound, cystoscopy and laparoscopy, also including assessing the development of the Wolffian tube and the Müllerian tube. The level and ratio of testosterone to dihydrotestosterone before and after hCG stimulation were evaluated for the function of Leydig cell and 5α-reductase-2. Gender role scales and sandbox games were used to assess gender role behavior. Genital sensitivity to androgen stimulation was assessed; A panel including 163 genes related to gender development were determined by second-generation sequencing in all 45 patients. Finally, a multidisciplinary team (MDT) makes a gender assignment after a comprehensive analysis mainly based on the molecular etiological diagnosis. Results: Thirty-nine out of 45 patients (87%) had an identifiable genetic etiology, and the remaining 6 (13%) were negative for genetic testing. Forty-five patients had EMS less than or equal to 3 points. Sexual psychological assessment was performed in 39 patients, with male dominance in 24 (62%) and female dominance in 15 (38%). The gender assignment was 23 cases (51%) for male and 19 cases (42%) for female, and 3 cases (7%) were not completely determined. Conclusions: Molecular diagnosis provides a strong basis for appropriate gender assignment of 46, XY DSD children with severe undermasculinisation. Based on molecular diagnosis, each DSD should be analyzed by professional MDT to analyze the clinical symptoms/signs, gonadal development, gonad tumor risk, external genital morphology, sexual psychological assessment, potential fertility opportunities, parental views, Social and cultural factors, etc. make appropriate gender assignment.

RESUMO

The International Disorders of Sex Development (I-DSD) and International Congenital AdrenalHyperplasia registry (I-CAH) Registries were originally developed over 10 years ago and have since supported several strands of research and led to approximately 20 peer-reviewed publications. In addition to acting as an indispensable tool for monitoring clinical and patient-centered outcomes for improving clinical practice, the registries can support a wide nature of primary and secondary research and can also act as a platform for pharmacovigilance, given their ability to collect real world patient data within a secure, ethics approved virtual research environment. The challenge for the future is to ensure that the research community continues to use the registries to improve our understanding of Disorders of Sex Development (DSD).

RESUMO

Non-classic congenital adrenal hyperplasia is a genetic condition caused by deficiency of 21- hydroxylase deficiency (NCAH). It is a milder and later onset form of a genetic condition known as congenital adrenal hyperplasia. We present four cases of non-classical congenital adrenal hyperplasia presented in gynae OPD foundation university medical college Fauji foundation hospital from Jan 2016 to March 2017. The presenting complaints were hirsuitim, menstrual problem and virilization of genitalia. Two girls were having primary amenorrhea while rests of two were having secondary amenorrhea. Two patients were already diagnosed as non-classical congenital adrenal hyperplasia due to ambiguous genitalia at the time of birth while the rest of two with marked clitoromegaly were diagnosed during workup in gynae OPD. Menarche was achieved successfully among those with primary amenorrhea after treatment. All four girls were referred to plastic surgery for clitoral reduction surgery. The post-surgery patient satisfaction level was high. Correct diagnosis of the disease can cure the patient instead of letting her live a life of being labeled with social stigmata of an intersex individual.

RESUMO

Prenatal undernutrition affects various physiological functions, such as metabolic and reproductive functions, after birth, and such changes are associated with the pathogeneses of certain diseases. It has been hypothesized that these changes are predictive adaptive responses that help individuals to endure similar conditions in the postnatal period. Thus, we evaluated the effects of prenatal undernutrition on the responses of the body weight (BW) regulation system and reproductive functions to fasting in the pre-pubertal period in male rats. Prenatally normally nourished and undernourished rats exhibited similar reductions in BW and visceral fat after 48 h fasting in the pre-pubertal period. Furthermore, these two groups displayed similar fasting-induced patterns of change in their hypothalamic levels of appetite regulatory factors; i.e., neuropeptide Y and pro-opiomelanocortin. These results indicate that prenatal undernutrition had no marked effects on BW regulation in male rats. On the other hand, serum luteinizing hormone and testosterone levels were decreased by 48 h fasting in the prenatally normally nourished rats, whereas the levels of these hormones did not change in the prenatally undernourished rats. However, the hypothalamic mRNA level of kisspeptin 1 (Kiss1), which is a positive regulator of gonadotropin-releasing hormone/gonadotropins, was reduced by fasting in both groups. These results indicate that prenatal undernutrition might attenuate fasting-induced reproductive dysfunction in the postnatal period; however, these changes might not be induced by alterations in the hypothalamic Kiss1 system. Further studies are needed to clarify the mechanisms involved in these changes in reproductive function.

RESUMO

BACKGROUND: Ambiguous genitalia refers to a form of differences of sex development (DSD) wherein the appearance of the external genitalia is atypical. This rare condition presents challenges in decision-making and clinical management. Review of historical data may reveal areas for clinical research to improve care for patients with ambiguous genitalia. OBJECTIVE: This chart review was performed to identify patients with ambiguous genitalia, and to classify them as having 46,XX DSD, 46,XY DSD, or sex chromosome DSD. Within these categories, we looked at establishment of specific diagnoses, type and frequency of other congenital anomalies and neoplasms, and gender assignment, as well as incidence of gender reassignment and transition. METHODS: We performed a retrospective chart review of patients diagnosed with DSD conditions from 1995 to 2016 using ICD9 codes. For the purpose of this study, review was limited to individuals assessed to have neonatal "ambiguous genitalia" or "indeterminate sex." RESULTS: Review identified 128 patients evaluated for ambiguous genitalia from 22 years of experience (Figure). Approximately half of these (53%) had 46,XY karyotype, 35% had 46,XX, and the remaining 12% had sex chromosome aberrations. Diagnostic rate for 46,XX DSD was higher at 64%, all of which were congenital adrenal hyperplasia, while diagnostic rate for 46,XY DSD was 11.7% for a molecularly confirmed diagnosis and 24% if clinical diagnoses were included. The most common anomalies included cardiac anomalies in 28/128 (22%), skeletal anomalies in 19/128 (15%), and failure to thrive or growth problems in 19/128 (15%). Additional congenital anomalies were found in 53 out of 128 patients (41%). There were three reported neoplasms in this group: gonadoblastoma, hepatoblastoma, and myelodysplastic syndrome with monosomy 7. Gender assignment was consistent with chromosomes in approximately 90% of XX and XY patients. There were three recorded gender reassignments or transitions. DISCUSSION: Diagnostic rate for ambiguous genitalia is low, especially in 46,XY DSD. Most neonates were assigned gender consistent with their chromosomes. Given the high rate of associated anomalies, screening for cardiac or other anomalies in patients with ambiguous genitalia may be beneficial. CONCLUSION: Patients with ambiguous genitalia often have additional congenital anomalies. Establishment of a specific diagnosis is uncommon in 46,XY patients. A few patients have gender reassignment outside of the newborn period. Ongoing collection of clinical data on this population may reveal new information regarding long-term health, quality of life, and establishment of more diagnoses with improved molecular techniques.

RESUMO

We present a video of our technique for resection of a large prostatic utricle (PU) in a patient who presented initially with disordered sexual development. His karyotype was 46XY, and phenotypically had penoscrotal hypospadias, bifid scrotum, and retractile right testis. An initial micturating cystourethrogram (MCUG) demonstrated the utricle but failed to cannulate the bladder. Being asymptomatic, we carried out staged repair of his hypospadias. Later, he started to have recurrent epididymo-orchitis with resistance to multiple antibiotics. Examination under anaesthesia was done and ruled out meatal or neo-urethral strictures. A subsequent MCUG demonstrated the large utricle and its relation to the bladder. We carried out a cystoscopic-assisted laparoscopic excision. There has been no consensus about the best surgical approach to resect a PU and most known procedures involved extensive pelvic dissection and carried a significant risk of damage to the pelvic nerves. The laparoscopic approach seems to be promising in this field as it provides proper view of the deep pelvis with reasonable magnification, less dissection and shorter postoperative pain and scarring. Cystoscopic assistance in this technique was a great addition to provide counter-traction movement and facilitate proper dissection.

RESUMO

The aim of the present study was to assess the responses of the gonopodium morphology and the gonadal and liver histology of adult male Cnesterodon decemmaculatus to sublethal long-term exposure concentrations of 17α-ethinylestradiol (EE2). Two experiments were conducted exposing the fish to waterborne concentrations of EE2 ranging from 20 ng/L to 200 ng/L for 8 wk, 12 wk, and 16 wk. Intersex gonads were observed after 8 wk and 16 wk in fish exposed to 200 ng EE2/L and 100 ng EE2/L, respectively. Oocytes' development from testis germ cells and replacement of the efferent duct periodic acid-Schiff-positive secretion surrounding spermatozeugmata by parenchymal tissue and duct structure alterations were the major observed changes in the gonads. In contrast, no response was observed in the gonopodium morphology. Liver histology was also altered, showing increasing steatosis, single-cell necrosis to generalized necrosis, and disruption of acinar organization from 100 ng EE2/L to 200 ng EE2/L. In summary, the present results showed that although EE2 was not able to alter the morphology of a developed gonopodium, it was capable of inducing development of testicular oocytes in adult male C. decemmaculatus at environmentally relevant concentrations. Thus, externally normal but intersex C. decemmaculatus males would be expected in the wastewater-receiving streams that the species inhabits. According to the literature, the present study would be the first indicating estrogen-induced intersex in adult male poeciliid. Environ Toxicol Chem 2017;36:1738-1745. © 2016 SETAC.

RESUMO

INTRODUCTION: The surgical management of girls with masculinized genitalia is gradually changing towards a more conservative approach. Reports on loss of clitoral sensitivity and related impairment of sexual function in women after feminizing genital surgery in childhood have been pivotal in this evolution. An exposed clitoral glans is occasionally seen at follow-up, and while patients may complain of aesthetics, no clitoral discomfort secondary to glans exposure has been reported. A technique has been developed to reconstruct the clitoral hood and the present study reports the preliminary results. OBJECTIVES: To report the novel technique and preliminary results of clitoral hood reconstruction to cover an exposed glans after previous clitoroplasty in patients with congenital adrenal hyperplasia (CAH). PATIENTS AND METHODS: Six female patients (mean age 13, range 4-21 years) with CAH sought medical help for clitoral concerns after previous reduction clitoroplasty. In two of the six patients, the main complaint was clitoral hypersensitivity or even pain. The clitoral glans was completely exposed in all patients, who were subsequently treated with a bi-laminar V-Y clitoral hoodplasty to create a mobile and natural-looking clitoral hood composed of an inner and outer preputial skin layer. RESULTS: Postoperative covering of the glans was complete in five patients, and partial in one. The two patients with pre-operative pain became asymptomatic; all six patients were pleased with the cosmetic postoperative results. CONCLUSION: Clitoral hoodplasty provides simple, yet effective, relief for women with cosmetic concerns or clitoral discomfort after previous feminizing surgery.
