    最近,有许多法律代表从选定的季度停止所有的医疗干预对儿童性别发育差异(DSD)。在这项关于渠务署管理决策的调查中,我们提炼印度利益相关者的观点:父母,医师,和成年DSD患者对他们的管理决策,以确定决策满意度或性别不安。
    调查领域包括患者人口统计,最终诊断,关于养育性别的决定,手术干预,利益相关者对性别分配的首选年龄的意见,最后的养育性别,和同意/不同意性别分配(性别不安)。
    总共记录了106个响应(66%的父母,34%的成年患者年龄在12-50岁之间)。在父母中,65/70(95%)更喜欢出生后不久分配的性别。所有成年患者都希望在出生后不久进行性别分配。关于手术的决定,74%的医生和75%的成年患者认为应该允许父母决定干预措施。在印度父母中,90%的人认为他们应该有权决定以孩子的最大利益进行手术,以获得安全的社会成长。总的来说,印度DSD患者的性别焦虑<1%(1/103,0.97%).
    印度主要利益相关者的主要偏好和意见(医生,父母,和成年DSD患者)支持DSD管理的现有方法,包括早期性别分配和必要的医疗干预。
    UNASSIGNED: Of late, there are many legal representations from select quarters to halt all medical interventions in children with differences of sex development (DSD). In this survey on management decisions in DSD, we distil the views of Indian stakeholders: parents, physicians, and grown-up patients with DSD on their management decisions to identify decisional satisfaction or gender dysphoria.
    UNASSIGNED: The survey domains included the patient demographics, final diagnosis, decision on the sex of rearing, surgical interventions, opinion of the stakeholders on the preferred age of sex assignment, final sex of rearing, and agreement/disagreement about sex assignment (gender dysphoria).
    UNASSIGNED: A total of 106 responses were recorded (66% parents, 34% grown-up patients aged 12-50 years). Among parents, 65/70 (95%) preferred the sex to be assigned soon after birth. All grown-up patients preferred sex to be assigned soon after birth. Regarding decisions on surgery, 74% of physicians and 75% of the grown-up patients felt parents should be allowed to decide interventions. Among Indian parents, 90% felt they should have the right to decide surgery in the best interest of their child for a safe social upbringing. Overall, gender dysphoria among Indian DSD patients was <1% (1/103, 0.97%).
    UNASSIGNED: The predominant preference and opinion of major Indian stakeholders (physicians, parents, and grown-up DSD patients) support the existing approach toward DSD management, including early sex assignment and necessary medical intervention.

    患有性腺肿瘤和性别分化障碍(DSD)的儿童很少见。
    探讨DSD患儿合并恶性性腺肿瘤的表现。
    一项2010-2020年的回顾性研究,评估了17名DSD儿童,包括13名女性,8个月到16年,先天性肾上腺增生,5-α还原酶缺乏症,雄激素不敏感综合征,特纳,Sywer,和Klinefelter综合征.
    10名儿童患有恶性性腺肿瘤;9名患有生殖细胞肿瘤,1名患有颗粒细胞肿瘤,而7名非恶性肿瘤患儿有性腺母细胞瘤,囊腺瘤(5名儿童),和囊肿。系统性畸形,肥胖,肿瘤标志物升高,90%的人观察到社会心理问题,90%,70%,与28.6%不同,50%的儿童患有恶性肿瘤,42.9%,14.35%,57.1%的儿童无恶性肿瘤。大多数(9/10)儿童>12岁,有心理社会问题,与0/7≤12岁的儿童不同。从8/17出现症状提示肿瘤的儿童,75%有恶性肿瘤,而来自9/17的DSD儿童,44%有恶性肿瘤。在八个月至六岁之间的3/10儿童中观察到恶性肿瘤,而7/10儿童有1-2期肿瘤。我们报告了一个孩子,被认定为女性,13岁,部分雄激素不敏感综合征(PAIS)46,XY,和睾丸乳头状浆液性囊腺瘤,基因组变异ARNM_000044.4:c.2750del。p。(F917Sfs*27)染色体Xq12,从未在患有PAIS或人口数据库(GnomAD)的人中发表。
    DSD诊断提出了许多挑战。患有DSD的人患恶性肿瘤的风险增加,特别是当肥胖和,存在系统性畸形;还有,这些儿童的社会心理问题与青春期后年龄有关。
    UNASSIGNED: Children having gonadal tumors and disorder of sex differentiation (DSD) are rare.
    UNASSIGNED: To investigate the presentation of DSD children with malignant gonadal tumors.
    UNASSIGNED: A retrospective study from 2010-2020, that evaluated 17 children with DSD, including 13 females, eight months to 16 years, with congenital adrenal hyperplasia, 5-alpha reductase deficiency, androgen insensitivity syndrome, Turner, Sywer, and Klinefelter syndromes.
    UNASSIGNED: Ten children had malignant gonadal tumor; nine had germ cell tumors and one person granulosa cell tumors, while seven children with non-malignant tumor had gonadoblastoma, cystadenoma (five children), and cysts. Systemic malformations, obesity, elevated tumor markers, and psychosocial issues were observed in 90%, 90%, 70%, and 50% of children with malignancy unlike 28.6%, 42.9%, 14.35%, and 57.1% children without malignancy respectively. Most (9/10) children >12 years, had psychosocial issues, unlike 0/7 children ≤12 years. From 8/17 children presenting with symptoms suggestive of tumor, 75% had malignancy, while from 9/17 children with DSD presentation, 44% had malignant tumors. Malignancy was observed in 3/10 children between eight months to age six, while 7/10 children had stage 1-2 tumors. We reported a child, identified as female, aged 13 years, with partial androgen insensivity syndrome (PAIS) 46,XY, and testicular papillary serous cystadenoma with genomic variant AR NM_000044.4:c.2750del. p.(F917Sfs*27) chromosome Xq12, never published in people with PAIS nor population databases (GnomAD).
    UNASSIGNED: DSD diagnosis raises numerous challenges. People with DSD have increased risk of malignancy, especially when obesity and, systemic malformations are present; also, psychosocial issues in these children are associated with postpubertal age.

    类固醇急性调节蛋白(STAR)基因的突变,它编码一种在类固醇激素合成中起关键作用的蛋白质,导致严重形式的先天性肾上腺增生(CAH),称为类脂CAH(LCAH)。LCAH表现为原发性肾上腺功能不全(PAI)和非典型生殖器。患有LCAH的个体需要肾上腺类固醇激素补充剂才能生存。STAR缺乏症男性的男性化从不完全到正常男性化不等。放射学检查显示肾上腺增大且充满脂质。一个10岁的男孩出生在二级血缘关系中,体重增加和色素沉着过度持续了1年。他在7个月大时被诊断为PAI,并接受氢化可的松和氟氢可的松治疗。动态肾上腺测试显示无法检测到激素储备。影像学检查发现肾上腺发育不良和睾丸肾上腺休息的小睾丸(TART)。遗传分析表明,与LCAH相关的外显子7中STAR的新纯合致病变异,c.814C>G(pArg272Gly)(OMIMNo.201710).测试显示,无症状的家庭成员和亲戚是该变体的杂合子。患者被诊断为肾上腺发育不良和TART的非经典LCAH。充足的激素补充导致TART消退。这种遗传变异是首次报道。
    A mutation in the steroidogenic acute regulatory protein (STAR) gene, which encodes a protein that plays a crucial role in steroid hormone synthesis, causes a severe form of congenital adrenal hyperplasia (CAH) known as lipoid CAH (LCAH). LCAH presents with primary adrenal insufficiency (PAI) as well as atypical genitalia. Individuals with LCAH require adrenal steroid hormone supplements for survival. Masculinization in males with STAR deficiency varies from incomplete to normal virilization. Radiological examinations reveal enlarged and lipid-laden adrenals. A 10-year-old boy born of second-degree consanguinity presented with weight gain and hyperpigmentation for 1 year. He was diagnosed with PAI at age 7 months and treated with hydrocortisone and fludrocortisone. Dynamic adrenal gland testing revealed undetectable hormone reserves. Imaging detected hypoplastic adrenals and a small testis with testicular adrenal rests (TART). Genetic analysis indicated a novel homozygous pathogenic variant of STAR in exon 7, c.814C > G(pArg272Gly) associated with LCAH (OMIM No. 201710). Testing revealed that asymptomatic family members and relatives were heterozygotes for the variant. The patient was diagnosed with nonclassic LCAH with hypoplastic adrenals and TART. Adequate hormone supplementation resulted in TART regression. This genetic variation is reported for the first time.

    性发育障碍(DSD)包括一组复杂的疾病,具有不同的临床表现,例如非典型生殖器,无法触及的睾丸,原发性闭经,或不孕症。除了与其他先天性异常有关,DSD在分配孩子的性别和未来的生育选择方面存在重大的道德问题。建立正确的诊断对于适当管理此类病例至关重要。各种成像模式,比如超声检查,生殖道,MRI,当补充详细的临床评估和核型分析时,是诊断病情的关键.本文试图为DSD的各种模式提供一种简洁的方法,这将帮助放射科医生解决这些诊断难题。
    Disorders of sexual development (DSD) comprise a complex group of conditions with varied clinical presentations, such as atypical genitalia, non-palpable testes, primary amenorrhea, or infertility. Besides being associated with other congenital anomalies, DSDs bear substantial ethical issues regarding assigning the sex of rearing to the child and future fertility options. Establishing the correct diagnosis is essential for the appropriate management of such cases. Various imaging modalities, such as ultrasonography, genitography, and MRI, when complemented with detailed clinical evaluation and karyotyping, are the key to diagnosing the condition. This article attempts to present a concise approach to various patterns of DSD, which will aid radiologists to solve these diagnostic dilemmas.

    背景:前列腺囊(PU)由苗勒管和泌尿生殖窦的尾部残余组成。如果其他苗勒式结构与PU相关联,则使用术语“阴道男性”。这项工作旨在调查发病率,管理,并对患有后尿道下裂的男性的扩大的PU和Mülerian残留物进行随访。
    方法:本研究对5年后尿道下裂病例进行回顾性分析。尿道下裂修复前,逆行尿道造影用于调查扩大的PU。随后,根据Ikoma评分进行分类,并通过核型分析和膀胱镜检查进行进一步评估.在有症状的子宫或阴道阳性的情况下,应进行手术切除。
    结果:在2015年至2020年期间,30名患者被纳入研究(表)。所有病例最初无症状。12例患者被诊断为PU增大;其中三个有阴道男性。1例会阴尿道下裂有单独的会阴开口用于PU。尿道下裂修复后,保守治疗的8例病例中有3例出现症状.
    结论:在不同的研究中,增大的PU和Mülerian残余物的发生率不同。然而,它随着尿道下裂严重程度的增加而增加。术前尿道造影有助于PU的诊断和分类,但它有其局限性。膀胱镜对诊断男性阴道更有优势。尽管大多数病例无症状,一些尿道下裂修复后出现症状。一些会阴尿道下裂患者的PU带有单独的会阴开口。
    结论:增大的PU或Müllerian残余物的发生率为40%。尽管病例在尿道下裂手术前无症状,一些病例在尿道下裂修复后出现症状。在某些情况下,PU或穆勒遗迹有一个单独的会阴开口。它们可以归类为需要手术干预的IkomaIII级的特定形式。
    The prostatic utricle (PU) consists of the caudal remnant of the Müllerian duct and the urogenital sinus. The term \"vagina masculina\" is used if other Müllerian structures are associated with the PU. This work aims to investigate the incidence, management, and follow up of enlarged PUs and Müllerian remnants in males with posterior hypospadias.
    This study presents a retrospective review of cases presented with posterior hypospadias over a 5-year period. Prior to hypospadias repair, retrograde urethrograms were used to investigate enlarged PU. Subsequently, they were classified according to the Ikoma score and further assessed by karyotyping and cystoscope. Surgical excision was indicated in cases with symptomatic utricles or vagina masculina.
    Thirty patients were included in the study in the period between 2015 and 2020 (Table). All cases were asymptomatic initially. Twelve patients were diagnosed with enlarged PU; three of them had vagina masculina. One case with perineal hypospadias had a separate perineal opening for PU. Following hypospadias repair, three of the eight cases treated conservatively turned symptomatic.
    The incidence of enlarged PU and Müllerian remnants varied among different studies. However, it increased as the severity of hypospadias increased. Preoperative urethrogram was helpful in the diagnosis and classification of PU, but it had its limitations. Cystoscope was more advantageous in diagnosing vagina masculina. Although most cases were asymptomatic, some turned symptomatic after hypospadias repair. Some cases with perineal hypospadias had PU with a separate perineal opening.
    The incidence of enlarged PUs or Müllerian remnants was 40%. Although cases were asymptomatic before hypospadias surgery, some cases turned into symptomatic after hypospadias repair. In some cases, the PU or Müllerian remnants had a separate perineal opening. They can be classified as a particular form of Ikoma grade III necessitating surgical intervention.

    在2019年年中,有关南非跑步者CasterSemenya有资格参加与其他女跑步者的比赛的争议最终导致了体育仲裁法院的判决。Semenya具有较高的内源性睾丸激素水平(可以说是性能优势),继发于性发育障碍。在这篇评论中,亚里士多德目的论用于捍卫“男性”和“女性”作为离散类别的存在。有人认为,一旦运动员的性别成立,他们应该被允许在没有强制性医疗的情况下在性别类别中竞争。的确,其他具有超出人类规范的有利遗传或表型特征的运动员被允许不受限制地作为人类参加比赛。在这两种情况下,如果运动员具有人类或男性或女性的本质属性,则应允许他们在这些类别中竞争;运动员的资格不应基于偶然的属性。
    In mid-2019, the controversy regarding South African runner Caster Semenya\'s eligibility to participate in competitions against other female runners culminated in a Court of Arbitration for Sport judgement. Semenya possessed high endogenous testosterone levels (arguably a performance advantage), secondary to a disorder of sexual development. In this commentary, Aristotelean teleology is used to defend the existence of \'male\' and \'female\' as discrete categories. It is argued that once the athlete\'s sex is established, they should be allowed to compete in the category of their sex without obligatory medical treatment. Indeed, other athletes who possess advantageous genetic or phenotypic traits that fall outside of the human norm have been allowed to compete as humans without restraint. In both cases, if an athlete possesses the essential attributes of being a human or being male or female they should be permitted to compete in those respective categories; athletes\' eligibilities should not be based upon accidental attributes.

    Gender assignment in infants born with a difference in sexual development (DSD) remains one of the many difficult decisions faced by the multi-disciplinary treatment team as some of these children develop gender identity disorder (GID) when they become adults. In this systematic review and meta-analysis we have analyzed the prevalence of GID in adolescent and adults with DSD. The secondary outcome of this review is to help physicians in appropriate sex assignment of DSD children so that development of GID in later life can be reduced.
    Pubmed/Index medicus were searched for \"intersex\" [All fields] OR \"disorders of sexual differentiation AND \"gender identity disorder OR gender dysphoria\" [MeSH] for articles published between 2005 and 2020. Typical diagnoses included were congenital adrenal hyperplasia (CAH); complete androgen insensitivity syndrome (CAIS); partial androgen insensitivity syndrome (PAIS); 5 alpha reductase deficiency (5ARD); 17-hydroxysteroid dehydrogenase deficiency (17HSD); mixed gonadal dysgenesis (MGD) and complete gonadal dysgenesis (CGD). GID or gender dysphoria (a strong feeling of dissatisfaction about oneself as male or female) prevalence in DSD patients older than 12 years of age was extracted. Within each condition, GID percentage was compared between female and male rearing.
    The I2statistics for prevalence of GID in DSD showed high heterogeneity with I2 of 93% (95% C.I 90-95%) among the 20 articles included. The overall prevalence of GID among those with DSD was 15% (95% C.I 13-17%). CAH reared females had 4% GID while CAH reared males had significantly higher GID at 15% (p = 0.0056). All CAIS patients were raised as females and the prevalence of GID was 1.7%. GID prevalence was 12% in PAIS raised as females while 25% in those raised as males with no significant difference (p = 0.134). GID was significantly high in 5ARD (53%) and 17HSD (53%) reared as females with half of them virilizing at puberty forcing a gender change. Among sex chromosome DSD 22% of those reared as females had GID while none in those raised as male with no significant difference.
    GID is low in women with CAH, CAIS and CGD favoring female sex of rearing in these conditions. GID is high in women with 5ARD/17HSD favoring male sex of rearing in these conditions. GID is variable in PAIS or MGD and no recommendations on sex of rearing could be made in these conditions. Each DSD patient is unique and they warrant multi-disciplinary care and long term psycho sexual support.

    Male factor infertility is a common problem. Evidence is emerging regarding the spectrum of systemic disease and illness harbored by infertile men who otherwise appear healthy. In this review, we present evidence that infertile men have poor overall health and increased morbidity and mortality, increased rates of both genitourinary and non-genitourinary malignancy, and greater risks of systemic disease. The review also highlights numerous genetic conditions associated with male infertility as well as emerging translational evidence of genitourinary birth defects and their impact on male infertility. Finally, parallels to the overall health of infertile women are presented. This review highlights the importance of a comprehensive health evaluation of men who present for an infertility assessment.

    Cytogenetic examination may be useful in determining the reason for primary amenorrhea in phenotypically female patients. The result 46, XY usually indicates two syndromes: complete androgen insensitivity or pure gonadal dysgenesis. We report a case of a patient, who due to acute lymphoblastic leukemia in childhood was treated with total body irradiation and bone marrow transplantation. Later on the patient presented with symptoms typical for premature ovarian failure and male karyotype in peripheral lymphocytes. The cytogenetic examination for peripheral cells showed normal female karyotype. Therefore, it has been concluded that ovarian function impairment resulted rather from the gonadotoxic effect of oncological treatment than as a disorder of sexual differentiation. The survival rates of childhood cancer are very high and some of the patients will experience premature ovarian failure. It must be remembered that after bone marrow transplantation karyotype of peripheral lymphocytes may be misleading.
