Abstract
Background Turner syndrome (TS) is the most common chromosomal abnormality in females. The diagnosis of TS is based on karyotyping of 30 blood lymphocytes. This technique does not rule out tissue mosaicism or low-grade mosaicism in the blood. Because of the associated risk of gonadoblastoma, mosaicism is especially important in case this involves a Y chromosome. Aims This study was set to determine the value of additional genetic studies such as fluorescent in situ hybridisation and the inclusion of buccal cells in search for mosaicism in TS patients. Settings and Design This cross-sectional, descriptive study was performed in Human Genetics Department, Medical Research Institute, Alexandria University. Materials and Methods Fluorescence in situ hybridisation technique was applied to lymphocyte cultures as well as buccal smears using centromeric probes for X and Y chromosomes. Genotype phenotype correlation was also evaluated. Statistical Analysis Used Descriptive study where categorical variables were described using number and percentage and continuous variables were described using mean and standard deviation. Results Fluorescence in situ hybridisation technique study detected hidden mosaicism in 60% of studied patients; 20% of patients had a cell line containing Y material, while 40% had variable degrees of X, XX mosaicism, and in the remaining 40% no second cell line was detected. Fluorescence in situ hybridisation study helped identify the origin of the marker to be Y in all patients. The introduction of an additional cell line helped in identifying mosaicism in patients with monosomy X. Virilisation signs were only observed among TS patients with Y cell line mosaicism. The clinical manifestations were more severe in patients with monosomy X than other mosaic cases. Conclusions Molecular cytogenetic investigation for all suspected cases of TS should be considered for appropriate treatment plan and genetic counselling.

Deferring gonadectomy in patients with turner syndrome with a genetic Y component is not a safe practice. J Pediatr Urol 2023:S1477-5131(22)00589-7. [PMID: 36740540 DOI: 10.1016/j.jpurol.2022.12.012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/21/2022] [Revised: 11/04/2022] [Accepted: 12/19/2022] [Indexed: 01/12/2023]
Abstract
INTRODUCTION Patients with Turner syndrome who harbor Y chromosome material are known to be at increased risk of developing germ cell neoplasms. The optimal timing to perform gonadectomy to reduce the risk of cancer development in these patients is not well defined. We present outcomes of Turner with a Y component (TSY) patients who underwent gonadectomy at our institution. HYPOTHESIS/OBJECTIVE We hypothesized that tumors could occur in a significant portion of TSY patients at any age and gonadectomy can be safely performed at diagnosis rather than deferred. STUDY DESIGN We performed an IRB-approved retrospective single center study in which we queried our institutions electronic health record to identify all patients with TSY who underwent gonadectomy at our institution from 2012 to 2021. RESULTS In our series of 18 consecutive TSY patients, a tumor was identified in 6 patients (33.3%): 4 (22.2%) with dysgerminoma (DG) [Fig. 1] and 2 (11.1%) with gonadoblastoma (GB). DISCUSSION Our cohort of 18 consecutive TSY who underwent gonadectomy over a 9-year period is the largest published single site cohort to date. Additionally, our patient who was found to have GB at 40 days is to our knowledge the youngest TSY patient to be diagnosed with GB in the literature. This patient's remarkably early incidence of tumor occurrence illustrates the urgency of protective gonadectomy. Given the high incidence of tumor formation in this population and the minimal morbidity associated with gonadectomy, we do not recommend delaying gonadectomy in this population for any reason. Our study is vulnerable to selection bias and confounding innate to any retrospective study. There was variation with respect to the frequency and timing of pre-operative imaging as a strict preoperative imaging protocol with sequential studies was not in place at our institution. Additionally, we do not have a comparison cohort of patients who are being followed without operative intervention as all TSY patients at our institution have undergone gonadectomy. CONCLUSION TSY patients cannot be safely observed for tumor formation based on clinical factors such as imaging or age. Gonadectomy is safe with a low complication rate and without tumor recurrence during three-year follow-up. We continue to recommend bilateral gonadectomy in this patient population at the time of diagnosis.

Abstract
INTRODUCTION A gonadectomy is currently recommended in patients with Turner syndrome (TS) and a 45,X/46,XY karyotype, due to a potential risk of gonadoblastoma (GB). However, the quality of evidence behind this recommendation is low. OBJECTIVE This study aimed to evaluate the prevalence of GB, its characteristics, as well as its risk factors, according to the type of Y chromosomal material in the karyotype. METHODS Our study within French rare disease centers included patients with TS and a 45,X/46,XY karyotype, without ambiguity of external genitalia. Clinical characteristics of the patients, their age at gonadectomy, and gonadal histology were recorded. The regions of the Y chromosome, the presence of TSPY regions, and the percentage of 45,X/46,XY mosaicism were evaluated. RESULTS A total of 70 patients were recruited, with a median age of 29.5 years (21.0-36.0) at the end of follow-up. Fifty-eight patients had a gonadectomy, at a mean age of 15 ± 8 years. GB was present in nine cases. Two were malignant, which were discovered at the age of 14 and 32 years, without metastases. Neither the percentage of XY cells within the 45,X/46,XY mosaicism nor the number of TSPY copies was statistically different in patients with or without GB (P = 0.37). However, the entire Y chromosome was frequent in patients with GB (6/9). CONCLUSIONS In our study, including a large number of patients with 45,X/46,XY TS, the prevalence of gonadoblastoma is 12.8%. An entire Y chromosome appears as the main risk factor of GB and should favor early gonadectomy. SIGNIFICANT STATEMENT About 10% of patients with TS have a karyotype containing Y chromosomal material: 45,X/46,XY. Its presence is related to the risk of GB. Therefore, a prophylactic gonadectomy is currently recommended in such patients. However, the quality of evidence is low. Our objective was to evaluate the prevalence of GB according to the type of Y-chromosomal material. We found a prevalence of GB of 12.8% in a cohort of 70 TS patients. No sign of hyperandrogenism was observed. The entire Y chromosome was the most frequent type of Y-material in patients with GB. As the prognosis of these tumors was good, a delay of surgery might be discussed.

Du H, Sun Y, Zhang Y, Wang S, Zhu H, Chen S, Pan H. Interaction of PM 2.5 and pre-pregnancy body mass index on birth weight: A nationwide prospective cohort study. Front Endocrinol (Lausanne) 2022; 13:963827. [PMID: 35957820 PMCID: PMC9360486 DOI: 10.3389/fendo.2022.963827] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/08/2022] [Accepted: 07/05/2022] [Indexed: 11/18/2022] Open
Abstract
BACKGROUND Fine particulate matter (PM2.5), one of the most common air pollutants worldwide, has been associated with many adverse birth outcomes in some studies. Pre-pregnancy body mass index (BMI) is an important indicator of maternal obesity that may also contribute to a wide range of birthweight outcomes. Both PM2.5 and maternal obesity have been found associated with issues on neonatal birthweight respectively, and more attentions and interests are focusing on their combined effect on pregnancy outcomes. PURPOSE To explore the modifying effect of pre-pregnancy BMI on the association between gestational PM2.5 and birthweight; to investigate the interactive effect between gestational PM2.5 and pre-pregnancy BMI on birthweight among pregnant women during three trimesters and the whole pregnancy. METHODS This nationwide cohort study used the National Free Preconception Health Examination Project (NFPHEP) data collected from January 1, 2010, to December 31, 2012. A total population of 248,501 Chinese women from 220 counties registered this project. Pre-pregnancy BMI as a common anthropometric examination was collected during preconception investigation, and gestational PM2.5 was derived from a hindcast model for historical PM2.5 estimation from satellite-retrieved aerosol optic depth. Subgroup analysis was conducted to explore a potential modifying effect on the association between PM2.5 and birthweight during pregnancy by four pre-pregnancy BMI subgroups. Interaction analysis by introducing product terms to multivariable linear regression was also used to examine whether there was an interactive relationship between PM2.5 and pre-pregnancy BMI. RESULTS Totally, 193,461 participants were included in our study. The average concentration of PM2.5 was 75.33 μg/m3. Higher exposure of PM2.5 during the entire pregnancy was associated with higher birthweight (17.15 g per 10 μg/m3; 95% CI:16.15, 18.17). Each 10 μg/m3 increase in PM2.5 during the first, second, and third trimesters was associated with increases in birthweight by 14.93 g (95%CI: 13.96, 15.89), 13.75 g (95% CI: 12.81, 14.69), and 8.79 g (95% CI: 8.09, 9.49), respectively. Higher pre-pregnancy BMI per kg/m2 was associated with an increase of birthweight by 7.012 g (95% CI: 6.121, 7.902). Product terms between PM2.5 and pre-pregnancy BMI were significant for the first, second trimesters, and the entire duration of pregnancy. CONCLUSIONS Our results found both gestational PM2.5 exposure and pre-pregnancy BMI respectively correlated with the increase of birthweight. A negative interaction between pre-pregnancy BMI and gestational PM2.5 was discovered in term of birthweight gain. Avoidance of high-dose exposure to PM2.5 during the early and middle stages of pregnancy and pre-pregnancy overweight/obesity may help prevent high birthweight.

Abstract
STUDY OBJECTIVE Girls with Turner syndrome with Y-chromosome material (TS + Y) are assumed to have nonfunctional gonads with increased tumor risk, therefore prophylactic gonadectomy is recommended at diagnosis. In this study we aimed to determine rates of spontaneous thelarche (ST) and spontaneous menarche (SM), and prevalence of gonadal tumor and malignancy in girls with TS + Y, to further inform discussions about gonadectomy. DESIGN Retrospective review of clinical and pathology data. SETTING Multicenter study involving 4 United States children's hospitals. PARTICIPANTS Patients included those with a genetically proven diagnosis of TS + Y and phenotypically female genitourinary exam. INTERVENTIONS Demographic characteristics, pubertal development, and gonadal pathology data were abstracted from clinical records. Data for ST were analyzed for patients aged 13 years and older and SM for patients older than 15 years. MAIN OUTCOME MEASURES ST, SM, prevalence of gonadal tumor, and malignancy. RESULTS Forty-four patients met inclusion criteria. Nineteen patients were 13 years or older; 8/19 (42%) had ST and reached Tanner stages 2-4 and 2 (11%) had normal ovarian pathology. Nineteen patients were 15 years or older; 2/19 (11%) had SM. Thirty-seven patients underwent gonadectomy; 35 had available pathology results. Gonadoblastoma was identified in 35/7 patients (19%), 1 in situ germ cell neoplasia, and 1 dysgerminoma (3%). One patient with bilateral gonadoblastoma had ST and SM. CONCLUSION In this multicenter cohort, 42% of girls with TS + Y entered puberty spontaneously and 11% had SM, supportive of gonadal function. Risk of tumor was similar to previous reports. To achieve informed decision-making, discussions about gonadectomy should incorporate potential for gonadal function and tumor risk.

Abstract
OBJECTIVE To describe the gonadal features of patients with 45,X/46,XY mosaicism, and to evaluate the prevalence of gonadal tumor in different phenotypes. MATERIALS AND METHODS The medical records of consecutive patients with 45,X/46,XY karyotype or its variants who had undergone gonadal biopsy or gonadectomy at a single institute between 1996 and 2017 were retrospectively reviewed. RESULTS Of 34 patients with 45,X/46,XY mosaicism, a unilateral dysgenetic testis and a contralateral streak gonad was detected in 20 patients (59%), bilateral streak gonads in 9 (26%), and bilateral dysgenetic testes in 5 (15%). A gonad composed of both streak and dysgenetic testicular portions was observed in 7 gonads of 6 patients. All streak gonads were removed, and bilateral gonadectomy was performed in 15 patients raised as girls. Pathologic examination revealed gonadal tumors in 6 of the 34 (18%) patients, including a gonadoblastoma in 7 gonads among 5 patients and an association of dysgerminoma with gonadoblastoma in 1 gonad. All 6 patients who developed gonadal tumor had female genitalia. Postoperative course was uneventful except 1 boy. A seminoma was developed in his soritaly scrotal testis at the age of 16 years. CONCLUSION The prevalence of gonadal tumor in patients with 45,X/46,XY mosaicism may vary according to the phenotype, and high in patients with female phenotype. Considering the increased risk of gonadal tumors in such patients, early investigation and individual management, including prophylactic gonadectomy, are recommended. In male patients, a close follow-up of the preserved testes is mandatory until adulthood.

Abstract
Ovarian gonadoblastoma coexisting with a dysgerminoma is extremely rare in patients with Turner syndrome (TS) and a Y chromosome. The cytological findings, including imprint cytology, of these unusual ovarian tumors have rarely been reported. We report a rare patient with a gonadoblastoma with dysgerminoma, 3.0 × 2.0 cm in size; she was a 19-year-old woman with TS and a Y chromosome. She underwent laparoscopic bilateral gonadectomy, and the tumor was classified as stage IA (pT1aNxM0) according to the International Federation of Gynecology and Obstetrics classification system. Intraoperative imprint cytology revealed two types of neoplastic cells: small tumor cells surrounding light green-stained or eosinophilic hyaline globules with marked calcification, suspicious for gonadoblastoma; and large, round, atypical cells with abundant cytoplasm, macronucleoli, and marked lymphocytic infiltration (two-cell pattern), suspicious for dysgerminoma. The cytology results in our patient may represent the second reported results of imprint cytology describing a gonadoblastoma with dysgerminoma. They are the first reported results in a patient with TS and a Y chromosome.

Abstract
OBJECTIVE To study the etiology and genetic diagnosis of children with short stature. METHODS A retrospective analysis was performed to study the etiological distribution and clinical features of 86 children with short stature. RESULTS A total of 6 causes were observed in these children, among which idiopathic short stature (ISS, 41%) and growth hormone deficiency (GHD, 29%) were the most common causes, followed by genetic diseases (14%). There were no significant differences in age at the time of diagnosis, body height, body length and weight at birth, body height of parents and insulin-like growth factor-1 levels between the genetic disease group and the ISS/GHD groups (P>0.05). Compared with the ISS group, the genetic disease group had significantly lower deviation from the 3rd percentile for the height of children of the same age and sex (ΔP3) and height standard deviation score (P<0.05), while there were no significant differences between the genetic disease and GHD groups (P>0.05). The analysis of the clinical manifestations for the genetic disease group showed heterogeneity and phenotypic overlap in children with different genetic diseases. CONCLUSIONS ISS, GHD and genetic diseases are major causes of short stature in children. For children with severe short stature, genetic testing should be performed to make a definitive diagnosis after GHD has been excluded.

Abstract
BACKGROUND Cardiovascular disease (CVD) presents the most serious health problems and contributes to the increased mortality in young women with Turner syndrome. Arterial hypertension in Turner syndrome patients is significantly more prevalent than that in a general age-matched control group. The aetiology of hypertension in Turner syndrome varies, even in the absence of cardiac anomalies and obvious structural renal abnormalities. Pheochromocytoma is an extremely rare cause among various etiologies for hypertension in patients with Turner syndrome. Here, we reported a pheochromocytoma as a rare cause of hypertension in Turner syndrome patient. CASE PRESENTATION A 21-year-old woman who has diagnosed with Turner syndrome with a karyotype of 46,X,i(X)(q10) visited for hypertension and mild headache. Transthoracic echography (TTE) showed no definite persistent ductus arteriosus shunt flow and cardiac valve abnormalities. Considering other important secondary causes like pheochromocytoma, hormonal studies were performed and the results showed increased serum norepinephrine, serum normetanephrine, and 24 h urine norepinephrine. We performed an abdominal computed tomography (CT) to confirm the location of pheochromocytoma. Abdominal CT showed a 1.9 cm right adrenal mass. I-131 meta-iodobenzylguanidine (MIBG) scintigraphy showed a right adrenal uptake. Laparoscopic adrenalectomy was performed and confirmed a pheochromocytoma. After surgery, blood pressure was within normal ranges and postoperative course was uneventful, and no recurrence developed via biochemical tests and abdominal CT until 24 months. CONCLUSION Our case and previous literatures suggest that hypertension caused by pheochromocytoma which is a rare but important and potentially lethal cause of hypertension in Turner syndrome. This case underlines the importance of early detection of pheochromocytoma in Turner syndrome. Clinicians should keep in mind that pheochromocytoma can be a cause of hypertension in patients with Turner syndrome.

Abstract
Non-epithelial ovarian tumours are rare neoplasms that occasionally arise in childhood and adolescence. They can be associated with various cancer susceptibility syndromes. The morphological overlap seen across these tumours and their rarity can make the diagnosis challenging. In the case of an incorrect diagnosis, the underlying genetic susceptibility may be missed. In this review, we outline the genetic background of ovarian non-epithelial tumours arising in children, emphasizing the genes harbouring pathogenic germline variants associated with each tumour type. Specifically, juvenile granulosa cell tumours, Sertoli-Leydig cell tumours, sex cord tumours with annular tubules, Sertoli cell tumours, germ cell tumours and small cell carcinoma of the ovary of hypercalcaemic type are discussed in this review. For each tumour type, we detail the personal and family history features and the presenting characteristics of the ovarian tumour as well as the pathological features and molecular markers that point towards a cancer predisposition syndrome. Throughout, we stress the need for specialised pathological review in difficult cases.

Abstract
Gonadal dysgenesis patients with Y chromosomal material are subject to increased risk for germ cell tumors. We report a case of an adolescent female presenting with Turner-like syndrome with primary amenorrhea and Tanner stage 1 breast development. Karyotype showed one X chromosome and a minute pericentromeric fragment of Y chromosome without any functional Y genes in all the cells, unlike a mosaic pattern, represented as 46,X,der(Y)del(Y)(p11.2)del(q11.2). Laparoscopic bilateral gonadectomy was performed due to presence of Y chromosome material and histopathology confirmed gonadoblastoma with a focus of dysgerminoma of the right ovary. A robotic-assisted surgical staging for dysgerminoma was performed which was confirmed to be negative for malignancy. This points at the putative genes for gonadoblastoma to be present around the centromere of the Y chromosome.

Abstract
Disorders (differences) of sexual development encompass a variety of conditions with atypical development of chromosomal, gonadal, or anatomic sex. Three of the most common differences of sex development conditions include congenital adrenal hyperplasia, complete androgen insensitivity, and Turner syndrome. Obstetrician-gynecologists who care for affected individuals in their practice must be familiar with the genetic, endocrine, and anatomic considerations of the most common conditions to provide optimal care. As women with these conditions transition to adult care, the gynecologist needs to assess the patient's understanding and educate her regarding her diagnosis and ongoing medical care. All of these conditions may affect self-perception, mental health, fertility, sexual function, and bone and cardiovascular health. Women with congenital adrenal hyperplasia need lifelong endocrine management and require genetic counseling before pregnancy. Women with androgen insensitivity syndrome require counseling regarding gonadectomy and hormone replacement therapy and may require vaginal elongation for intercourse. Most women with Turner syndrome experience premature ovarian insufficiency and require long-term estrogen replacement. Women with Turner syndrome often have congenital anomalies and autoimmune disorders, which require regular monitoring and care during adulthood. The purpose of this review is to provide the obstetrician-gynecologist who cares for adult women with the most common disorders (differences) of sexual development conditions an outline of the current recommendations for screening and ongoing health care with particular emphasis on the underlying genetics, management of subfertility, infertility and sexual concerns, approach to hypogonadism, and understanding of associated comorbidities.

Abstract
An understanding of the role of inherited cancer predisposition syndromes in pediatric tumor diagnoses continues to develop as more information is learned through the application of genomic technology. Identifying patients and their relatives at an increased risk for developing cancer is an important step in the care of this patient population. The purpose of this review is to highlight various tumor types that arise in the pediatric population and the cancer predisposition syndromes associated with those tumors. The review serves as a guide for recognizing genes and conditions to consider when a pediatric cancer referral presents to the genetics clinic.

Abstract
BACKGROUND It is recognised that individuals with a 45,X/46,XY karyotype, known as Turner mosaic syndrome with Y chromosome material (TMSY), have an increased risk of developing gonadoblastoma (GB), which may then devolve into one of a number of germ cell malignancies. Hence, children with TMSY are usually recommended to undergo prophylactic gonadectomy. OBJECTIVE We designed this study to describe the phenotypic features of our series of children with TMSY who underwent prophylactic gonadectomy in order to evaluate the prevalence of GB and germ cell malignancies in their resected specimens. STUDY DESIGN This is a retrospective case series wherein we comprehensively reviewed the clinical, histological, and cytogenetic features of all patients who underwent prophylactic gonadectomy at three tertiary paediatric referral centres over 16 years. Cases were identified from surgical logbooks and through the institutional histopathology database. Data were collected with particular reference to clinical phenotype, predominant karyotype cell line, operative management, anatomical findings and the presence of neoplastic changes. RESULTS Fourteen children ranging in age at the time of surgery from 2 weeks to 17 years were included in the series. Eleven children were reared as females. The three children who were reared as males had severe penoscrotal hypospadias. The 46,XY cell line was the predominant cell line in seven (50%) cases in blood lymphocytes. The resected specimens from four patients (28.6%) contained GB, with three patients having bilateral GB. This sub-group of patients with GB were aged 5 months, 48 months, 71 months, and 13 years. GB arose in one patient with and three patients without genital virilisation. There was no focus of invasive germ cell tumour in any specimen. DISCUSSION GB may be present in infants with TMSY as young as 5 months, even with low levels of Y chromosome material. The prevalence of GB in prophylactic gonadectomy specimens is similar to many previously reported series, although the absence of dysgerminoma in our series is reassuring. The exclusive presence of GB in intra-abdominal gonads is in keeping with the findings of several other series. CONCLUSION Owing to the presence of gonadoblastoma in the gonads of children with TMSY as young as 5 months, we recommend that all patients with intra-abdominal gonads in the context of TMSY should duly undergo prophylactic gonadectomy, although the timing of such surgery can be discussed with parents during counselling regarding the risk of malignancy.

Abstract
Prophylactic gonadectomy is recommended in patients with 45,X mosaicism with the Y chromosome and presenting a female phenotype because of the risk of gonadoblastoma development. The characteristics of this disorder remain unclear because of its low incidence. We report 4 patients with 45,X mosaicism with the Y chromosome and presenting complete female external genitalia. We analyzed the characteristics and the macroscopic and histopathological findings of their gonads and performed hormonal assays of the 4 patients. All 4 patients were referred to us with short stature as the chief complaint. Chromosomal studies revealed 45,X/47,XYY in 1, and the others had a 45,X/46,XY karyotype. Three patients (6 gonads) underwent laparoscopic bilateral gonadectomy. The macroscopic appearance of gonads of 1 patient was similar to an ovary, whereas gonads of the rest appeared as streak gonads. The histopathological findings revealed bilateral gonadoblastoma in 1 patient, although the macroscopic findings did not show tumor characteristics. It is impossible to distinguish the histopathological findings of gonads according to their macroscopic appearance among patients with 45,X mosaicism with the Y chromosome and presenting a female phenotype.

Abstract
Turner syndrome (TS) is a common genetic disorder in females associated with the absence of complete or parts of a second sex chromosome. In 5-12% of patients, mosaicism for a cell line with a normal or structurally abnormal Y chromosome is identified. The presence of Y-chromosome material is of medical importance because it results in an increased risk of developing gonadal tumours and virilisation. Molecular study and fluorescence in situ hybridisation approaches were used to study 74 Brazilian TS patients in order to determine the frequency of hidden Y-chromosome mosaicism, and to infer the potential risk of developing malignancies. Additionally, we describe one TS girl with a very uncommon karyotype 46,X,der(X)t(X;Y)(p22.3?2;q11.23) comprising a partial monosomy of Xp22.3?2 together with a partial monosomy of Yq11.23. The presence of cryptic Y-chromosome-specific sequences was detected in 2.7% of the cases. All patients with Y-chromosome-positive sequences showed normal female genitalia with no signs of virilisation. Indeed, the clinical data from Y-chromosome-positive patients was very similar to those with Y-negative results. Therefore, we recommend that the search for hidden Y-chromosome mosaicism should be carried out in all TS cases and not be limited to virilised patients or carriers of a specific karyotype.

Abstract
BACKGROUND/PURPOSE Gonadectomy is recommended in Turner syndrome (TS) patients with Y-chromosome material due to high risk of tumor in the dysgenetic gonads. No recommendations exist on whether concurrent salpingectomy should be performed. METHODS A retrospective chart review of surgical procedure and histopathology in TS patients with Y-chromosome enrolled in a TS database was undertaken at Cincinnati Children's Hospital Medical Center. An electronic survey was sent to members of the International Pediatric Endosurgery Group to assess prevalent practice patterns and attitudes on gonadectomy and concurrent salpingectomy in this population. RESULTS In March 2011, 12/158 (8%) TS girls (mean age 6.6 years) enrolled in the database had TS with Y-chromosome. Gonadoblastoma was identified in 4/12 (33%) patients and 2/4 had malignant transformation to dysgerminoma and teratoma. Approach to gonadectomy was varied and 3/12 had concurrent salpingectomy. Fifty-four laparoscopic surgeons responded to the survey with no clear consensus on whether salpingectomy should be concurrently performed. CONCLUSIONS TS patients with Y-chromosome have an increased risk of gonadal tumor development and gonadectomy is recommended. While there is no consensus among pediatric laparoscopic surgeons on concurrent salpingectomy, it is reasonable to consider this combination procedure.

Abstract
Most women diagnosed with malignant ovarian germ cell tumors have curable disease and experience excellent survival with manageable treatment-associated morbidity, related both to tumor biology and improvements in treatment over the last 4 decades. Malignant ovarian germ cell tumors occur predominantly in girls, adolescents, and young women and are often unilateral tumors of early stage, although advanced-stage disease occurs in approximately 30% of patients. Tumors are usually chemosensitive, thereby allowing fertility-sparing surgery in most women with high chance of cure. Differences in practice do exist among providers in various subspecialties and geographic areas. In most settings, collaborative efforts among specialties allow the optimal treatment of women with these rare tumors, and implementation of standard guidelines at an international level should translate to effective clinical trial design, rapid accrual to clinical trials, and universally improved patient outcomes. This consensus guideline represents a summary of recommendations for diagnosis and management that has been agreed upon by cooperative groups worldwide. It builds upon individual publications including previously published summary documents and provides the most current practice standards validated worldwide.

Abstract
The presence of Y chromosome material in patients with disorders of sex development (DSD) has been associated with a high risk of gonadoblastoma. Therefore, gonadectomy is recommended in females with bilateral streak gonads and Y chromosome material. The aim of this study was to present our experience with prophylactic gonadectomy in those patients and evaluate their risk of gonadal tumors. We reviewed the charts of 11 female patients who had bilateral gonadectomy (by laparoscopically in 9 patients, by laparotomy in 2 patients) between 1991 and 2012 at our hospital. Seven patients with Turner syndrome (TS) who carry a Y mosaic karyotype in peripheral blood, 3 patients with Swyer syndrome and one patient with Frasier syndrome were included. All patients had an unambiguous female phenotype. Age at surgery and follow-up ranged from 2 to 23 (mean 11) and 0.5 to 20 (mean 8) yr, respectively. Pathologic examination revealed gonadal tumors in 6 of 11 patients (56%), including 4 with TS, the youngest of which was 2 yr old, one with Swyer syndrome and one with Frasier syndrome. A gonadoblastoma was detected in 8 gonads, and an association of dysgerminoma with gonadoblastoma was detected in 2 gonads. Imaging studies showed no metastasis, and the postoperative course was uneventful in all patients. In our series of DSD patients with bilateral streak gonads and Y chromosome material, the risk of gonadal tumor was high. Considering the early occurrence of gonadoblastoma and its high potential for malignant transformation, early prophylactic gonadectomy is strongly recommended.

Abstract
A systematic search for a hidden Y-chromosome mosaicism, in Turner syndrome (TS) patients is justified by the evaluation of the risk of development of germ cell tumors. In this study, we analyzed cryptic Y-chromosome derivatives by polymerase chain reaction (PCR) coupled with fluorescence in situ hybridization (FISH) using Y-specific sequences in patients with TS, and validated this methodology. Unrelated patients with TS (n=32) of Mexican mestizo ethnic origin were diagnosed using cytogenetic analysis. Clinical assessment, endocrine evaluation, karyotyping, FISH and PCR analysis of the Y-chromosomal loci were performed. We found that 9.4% (3 out of 32) patients with TS had Y-chromosome material. Two patients showed Y-chromosome by conventional cytogenetics. One patient had no Y-chromosome by initial karyotyping (45, X) but was positive by lymphocyte PCR DNA analysis of the Y-sequence-specific sex-determining region Y (SRY) gene. Our results suggest that the detection of the Y-chromosome material using sensitive methods, such as PCR coupled with FISH, should be carried out in all patients with TS and should not be limited to TS patients with cytogenetically identifiable Y-chromosome and/or virilization.

Abstract
CONTEXT Turner syndrome (TS), in which there is loss of all or part of one sex chromosome, occurs in one in 2500 live-born females and is associated with characteristic findings. Detailed healthcare checklists and screening guidelines are commonly used to detect known complications affecting individuals with TS. Even with the use of these guidelines, there remains an increased morbidity and mortality seen in TS as compared to the general population, leading to significant controversy on optimal management of several aspects of TS. EVIDENCE ACQUISITION AND SYNTHESIS A PubMed search of articles from the past 15 yr identified available studies related to the diagnosis and management of common issues related to TS as well as important historical articles. This review summarizes studies through January 2012 and highlights recent developments. CONCLUSIONS There remain many areas of uncertainty in the diagnosis and management of TS. Generalizations from experience in the care of other conditions in isolation (such as poor growth, follow-up of cardiac disease, or the treatment of ovarian failure) cannot be broadly applied when caring for individuals with TS. Specific differences include treatment of growth failure as early as possible; acquisition of adequate baseline cardiac studies, followed by serial magnetic resonance imaging, targeted to identify findings unique to TS that address the increased risk of aortic dissection; initiation of hormone replacement at the normal age of puberty, preferentially with transdermal estradiol; and detailed patient counseling to explain the long-term health risks commonly associated with this disorder. A revised paradigm of care using a standardized multidisciplinary evaluation, supplementing screening tests as advocated by expert opinion guidelines, can aid clinicians in interpreting the results of diagnostic testing in the context of TS. This approach optimizes medical care for women with TS and may reduce the increased morbidity and mortality currently seen in this population.

Abstract
We report a 17-year-old girl evaluated for primary amenorrhea. Cytogenetic analysis of the peripheral blood lymphocytes revealed normal autosomes with 46X inv (Y) confirming the diagnosis of Turner's syndrome with Y cell line. Treatment was initiated with conjugated estrogen while recommending bilateral prophylactic oophorectomy to the patient. One year later the patient presented with abdominal mass, biopsy of the specimen following resection confirmed dysgerminoma originating from right ovary with no invasion or metastasis. The literature is reviewed with regard to the various pathogenetic mechanisms proposed for the development of germ cell tumors in ovary, the cytogenetic findings and recommendations to handle such scenario.

Abstract
Whole-genome genetic diagnostics has changed the clinical landscape of pediatric and adolescent medicine. In this article, we review the history of clinical cytogenetics as the field has progressed from studying chromosomes prepared from cells squashed between 2 slides to the high-resolution, whole-genome technology in use today, which has allowed for the identification of numerous previously unrecognized microdeletion and microduplication syndromes. Types of arrays and the data they collect are addressed, as are the types of results that array comparative genomic hybridization studies may generate. Throughout the review, we present case stories to illustrate the familiar (Down syndrome) and the new (a never-before reported microdeletion on the long arm of chromosome 12).

Abstract
BACKGROUND The aim of this study was to investigate the frequency of gonadal tumors among patients with Turner syndrome (TS) carrying Y-derivative sequences in their chromosomal constitution. METHODS Six out of 260 patients with TS were selected based on mosaicism of the entire Y chromosome; 10 were included because Y-derivative sequences have been detected by PCR with specific oligonucleotides (sex-determining region on the Y, testis specific-protein, Y and DYZ3) and further confirmed by FISH. The 16 patients were subjected to bilateral gonadectomy at ages varying from 8.7 to 18.2 years. Both histopathological investigation with hematoxylin and eosin (H&E) and immunohistochemical analysis with anti-octamer-binding transcription factor 4 (OCT4) antibody were performed. RESULTS Gonadal neoplasia was not detected in any of the 32 gonads evaluated by H&E; however, four gonads (12%) from three patients (19%) had positive OCT4 staining in 50-80% of nuclei, suggesting the existence of germ cell tumors (gonadoblastoma or in situ carcinoma). CONCLUSIONS Evaluation of the real risk of development of gonadal tumors in TS patients with Y-derivative sequences in their chromosomal constitution may require a specific histopathological study, such as immunohistochemistry with OCT4.

Abstract
BACKGROUND Gonadal dysgenesis encompasses a variety of sexual differentiation disorders. Within this population of patients, there is an increased risk of gonadal tumor formation. CASES In this case series of three patients, two with Swyer's syndrome (complete gonadal dysgenesis) and one with mosaic Turner's syndrome, three separate histologic subtypes of tumors were identified: dysgerminoma, seminoma, and gonadoblastoma. The patients with dysgerminoma and seminoma had regular menses and were without recurrent disease. We recommend that the patient with gonadoblastoma start on hormone therapy. CONCLUSION Once the diagnosis of gonadal dysgenesis is made, prophylactic gonadectomy should be performed owing to the probability of malignant transformation. These patients illustrate the potential different presentations with gonadal dysgenesis and the importance of complete evaluation of patients with primary amenorrhea.

Abstract
OBJECTIVE To evaluate the effect of the improvement of chromosome analysis on the cytogenetic findings of Turner syndrome (TS) patients. METHODS Retrospective study of the results of the karyotypes of 260 patients with TS, regarding banding techniques, number of cells analyzed and results of investigation of Y-chromosome sequences. According to karyotype, divided in 45,X; sex chromosome mosaicism without Y; structural aberrations of sex chromosomes with or without mosaicism; sex chromosome mosaicism with Y. RESULTS 45,X was the most frequent karyotype (108), followed by structural aberrations (88) and mosaics (58 without Y and 6 with Y). Introduction of banding techniques and increase in the number of cells analyzed resulted in progressive decrease of 45,X karyotype and increase of structural aberrations. The study of Y-chromosome sequences was performed in 96 cases of which 10 resulted positive. CONCLUSIONS Improvement of chromosome analysis over the years has modified the cytogenetic profile of TS.

Abstract
CONTEXT Nijmegen breakage syndrome (NBS) is a severe chromosomal instability disorder characterized by microcephaly, growth retardation, immune deficiency, and predisposition for malignancy. It is caused by hypomorphic mutations in the NBN gene, which product belongs to the protein complex critical for processing DNA double-strand breaks during mitotic and meiotic recombination. Data on gonadal function in patients with NBS are limited. OBJECTIVE Growth and sexual development, along with hormonal assays, were evaluated in girls and young women with NBS homozygous for c.657_661del5 mutation. STUDY DESIGN AND PATIENTS The group comprised 37 girls and young women with NBS (ages, 0.17-24.25 yr), followed between 1993 and 2008. Patients were divided into three age groups: 1) 1-3 yr; 2) 4-9 yr; and 3) 10 yr and older. Growth, puberty, concentrations of gonadotropins and 17-beta-estradiol, bone age, and pelvic ultrasound were assessed. RESULTS None of the patients presented a typical growth spurt; the adult height ranged between the 3rd and 25th centiles. Median bone age was delayed by 4.05 yr. Pubarche reached stadium P2 in eight patients and P3 in two patients. In all but one girl, thelarche did not exceed Th2, with low 17beta-estradiol levels. Gonadotropin levels showed a biphasic pattern, with median FSH values of 55.0, 10.9, and 81.9 IU/liter, and LH of 3.2, 0.8, and 21.0 IU/liter in consecutive age groups. Ultrasound visualized small ovaries or solid streaks and the hypoplastic uterus. CONCLUSIONS Primary ovarian insufficiency and the associated hypergonadotropic hypogonadism are hallmark manifestations in girls and young women with NBS. Our findings emphasize the need for long-term endocrinological and interdisciplinary supervision of these patients.

Abstract
A 15-year-old girl with Turner syndrome was unexpectedly found to have a left suprarenal mass. Extensive investigations showed a clinically and biochemically inapparent mass. Computed tomography disclosed a well-defined solid lesion in the left adrenal measuring 6.5 x 5 cm with minimal contrast enhancement. Laparoscopic adrenalectomy was done. Histologic examination revealed an encapsulated mass originated from the left adrenal medulla. Tumor tissue comprised abundant collagen fibers and spindloid cells admixed with mature ganglion cells. The tumor was diagnosed as left adrenal ganglioneuroma. According to literature, we report the eighth case of ganglioneuroma complicating Turner syndrome. Patients with this syndrome are predisposed to the development of neuroblastoma and related tumors. Reasons for this predisposition might relate to genetic and hormonal factors. Given that these tumors are often limited stage and of good prognosis, we recommend their screening in all patients with Turner syndrome.

Abstract
CONTEXT Recent advances in the understanding of genetic conditions involving the female genital tract and mechanisms of carcinogenesis in this setting affect patient management and thus necessitate appropriate pathologic evaluation of specimens. In the past, specimens from prophylactic surgery were a rarity; however, they are now more frequently encountered and often require a significant variation from routine processing methods. Pathologists also receive more specimens requiring prospective workup for possible underlying genetic conditions such as microsatellite instability. OBJECTIVE To summarize the current knowledge of important genetic and hereditary conditions affecting the female reproductive organs while highlighting the resulting practical significance for specimen handling, "grossing," and microscopic evaluation in gynecologic pathology. DATA SOURCES This update is based on a review of recent peer-reviewed literature and the experience with cases at the parent institutions. CONCLUSIONS Gynecologic specimens received from patients with certain genetic conditions require specific clinicopathologic knowledge for appropriate pathologic examination. The evaluation of prophylactic resection specimens focuses on the detection of cancer precursors and possible occult disease, which may require a more thorough and detailed examination than an obvious carcinoma. Standardized protocols for handling prophylactic gynecologic resection specimens are available for some, but not all, types of specimens. The prospective evaluation of a gynecologic pathology specimen for potential genetic conditions such as microsatellite instability is a very recent subject. Currently, well-established protocols are not available; however, as clinical and prognostic significance has become more clearly elucidated, familiarity with this evolving field is increasingly important to properly assess these pathologic specimens.

Abstract
CONTEXT 45,X/46,Xidic(Y) mosaicism demands careful and thorough study because of both its variable clinical features and its potential complications. CASE REPORT The present case relates to a three-year-old girl with the mosaic karyotype 46,X,idic(Y)(q11.2)[23]/45,X[6]. She had no signs of virilization or Turner's syndrome phenotype, but she was referred to our hospital because she presented reduced growth rate, abnormal facies and a melanotic nevus. After examination, she underwent prophylactic gonadectomy because of the risk of gonadoblastoma. Cytogenetic analysis on the streak gonads and blood showed significant differences in the 45,X cell line between these two tissues. The presence of the sex-determining region Y (SRY) gene did not determine male differentiation, which meant in the present case that the predominance of the X cell line in the gonadal tissue was probably due to the determining factor for female sexual differentiation.

Abstract
In the present study, 73 cases with a clinical diagnosis of Turner syndrome, or with primary or secondary amenorrhoea without frank Turner phenotype, were evaluated for presence of low level Y chromosome mosaicism using molecular methods. Fluorescence in-situ hybridization for centromere and q arm of the Y chromosome and nested polymerase chain reaction for the sex determining region on Y (SRY) gene were performed in peripheral blood, buccal cells and gonadal biopsies. The overall frequency of Y chromosome mosaicism was found to be 18% (13/73 cases). Four cases (16%) of Turner syndrome had Y chromosome mosaicism, seven cases (28%) with primary amenorrhoea and two cases (9%) with secondary amenorrhoea had Y chromosome mosaicism. Histologically detectable gonadoblastoma was observed in one of seven cases (14%) that had Y chromosome mosaicism. This frequency is lower than that reported previously, underscoring the need for large prospective investigations to determine the frequency of Y chromosome mosaicism and occurrence of gonadoblastoma in cases of Turner syndrome and other forms of amenorrhoea.

Abstract
In recent years, our understanding of neoplasms composed of germ cells and sex cord derivatives has increased. In this review, advances in the classification and pathology of ovarian germ cell-sex cord-stromal tumors are discussed. Only 2 neoplasms, each with a distinctive pathogenesis and clinicopathologic features, are included in this category. Gonadoblastoma is a tumor that usually occurs in the dysgenetic gonads of intersex patients that have a Y chromosome, whereas mixed germ cell-sex cord-stromal tumor arises in normal gonads in patients without sex chromosomal abnormalities. Ovarian mixed germ cell-sex cord-stromal tumors differ from their testicular counterparts in their histological appearance, immunohistochemical staining reactions, and biological behavior probably because the latter show a greater degree of maturity of their germ cell component. The introduction of cisplatin-based chemotherapy and the application of tumor markers have dramatically improved the clinical outlook for those patients who develop secondary malignant germ cell neoplasms.

Abstract
A 45,X karyotype is one of the common chromosomal abnormalities characterized by short stature, lack of development of secondary sexual characteristics, webbed neck and cubitus valgus. This phenotype was described by Turner in 1938 and was called Turner syndrome (TS). About 40-60% of the patients with TS phenotype have a 45,X karyotype, the rest either have a structurally abnormal X or Y chromosome or mosaicism with a second cell line. Determination of Y chromosome derivatives in patients with a 45,X karyotype is important for the management of these patients due to increased risk of gonadoblastoma. Low level mosaicism of Y chromosome may be missed by cytogenetic methods. The aim of our study is to analyze cryptic Y chromosome derivatives using Y specific sequences in 40 Turkish patients with a pure 45,X karyotype. Fourteen different Y specific sequences along the Y chromosome were selected for the detection of cryptic Y chromosome material by PCR analysis. The present study demonstrated that 2 patients with a 45,X karyotype (5%) have Y specific sequences except sex related region Y (SRY). One of them had displayed enhanced virilisation whereas other showed no virilisation. In conclusion, it has been found by PCR analysis that 5% of patients with a 45,X karyotype have Y chromosome sequences in the absence of any marker chromosome by cytogenetic analysis. The data also suggest that the patients with a 45,X karyotype should be analyzed for the presence of Y chromosome derivatives by sensitive methods, such as PCR, in order to calculate the future risk of developing gonadoblastoma.

Abstract
Continuing new insights into the biology of sexual development and advances in chromosome analysis have led to early identification and prompt treatment of the intersexual patient, the results of which facilitate a more normal life for affected individuals. Based on these advances, a classification of abnormal sexual development has been developed and refined that correlates the gonadal and genital anatomy with the chromosomal findings and specific genetic or metabolic defects. In a shift from a classification anchored on whether the intersex revolves about a specific gene or whole chromosomal abnormality, the current classification is organised by broader categories into which the intersexual disorders are divided into 'abnormalities of genital differentiation', due largely to the abnormal production or sensitivity of a single hormone, or 'abnormalities in sex determination', due to abnormal gonadal differentiation, usually testicular, with or without chromosomal aberration. The current classification is an integrated approach to this complex group of disorders and is organised according to the manner by which patients present as well as on the pathophysiological basis of the defect. The classification also groups patients who are at high risk for development of gonadal neoplasia.
