Vitrification versus slow freezing of human ovarian tissue: a systematic review and meta-analysis of histological outcomes.

A systematic review and meta-analysis of pertinent literature published from 2006 to January 2022 were conducted to study and compare vitrification and slow freezing, the two prominent methods of ovarian tissue cryopreservation. The primary outcome measures for this study were (1) proportion of intact primordial follicles, (2) proportion of intact stromal cells, (3) proportion of DNA fragmentation in primordial follicles, and (4) mean primordial follicle density. This meta-analysis of 19 studies revealed a significantly greater proportion of intact stromal cells in vitrified tissue versus slow-frozen tissue. No significant differences upon pooled analyses were observed between the two cryopreservation methods with respect to the proportion of intact primordial follicles, proportion of DNA fragmentation, or mean primordial follicle density. Due to differences seen in stromal cell viability, vitrification may be a preferred option to preserve histology of tissue. However, more work should be done to compare the two freezing techniques with less heterogeneity caused by patients, samples, and protocols.

Oral Contraceptive Use in Obese Adolescents: A Cautionary Tale.

Venous thromboembolism (VTE) is a life-threatening complication rarely encountered with the use of combined oral contraceptives (COCs). Obesity is an additional thrombosis risk factor that has been shown to further increase the risk of VTE with the use of COCs. We present 5 cases of obese adolescents (body mass index >30 kg/m2) who encountered thrombosis complications while on COCs. Although the absolute risk of VTE events in the setting of COCs is rare, caution should be observed when choosing hormonal therapy and safer COCs alternatives discussed with adolescents who are obese.

Autoimmune progesterone dermatitis in the adolescent population.

BACKGROUND/OBJECTIVE: Autoimmune progesterone dermatitis (APD) is a rare autoimmune hypersensitivity reaction that occurs cyclically at the peak of endogenous progesterone production during the menstrual cycle in women. No study characterizing APD in the adolescent population is found; it appears likely to be underdiagnosed and undertreated. METHODS: A retrospective, single-center, review of all adolescent and pediatric patients (<20 years old at onset) with documented diagnosis of APD. RESULTS: Seventeen adolescent APD patients were included (mean age at diagnosis: 14.4 ± 2 years, mean interval of 13.6 ± 11.1 months between symptom onset and diagnosis). Twelve patients presented with urticaria, two with fixed drug eruption. Erythema multiforme, eczema, and recurrent aphthous stomatitis were present in one patient each. Exposure to exogenous progestin was present in two patients prior to disease onset. Progesterone skin test was performed in six patients with positive results in two. Fourteen patients received antihistamines and/or a topical corticosteroid. Combined oral contraceptives (COCs) were given to eleven patients, in seven via continuous daily dosing. Gonadotropin-releasing hormone agonist (GnRHa) was used in five, progesterone desensitization in four, omalizumab in two, and danazol in one patient. CONCLUSIONS: Adolescent APD is associated with a significant delay in diagnosis. The most common manifestation is urticaria. Exogenous exposure to progestins is uncommon in adolescent APD. Continuous COC, GnRHa, and progesterone desensitization have been used to control symptoms. Large, multicenter studies are required to better define, diagnose, and treat this under recognized condition among adolescent patients.

A rare case of childhood mucous membrane pemphigoid involving the oral and genital mucosa.

Mucous membrane pemphigoid (MMP) is a rare chronic immunobullous disease that involves the mucous membranes and may result in significant scarring and complications if diagnosis is delayed. MMP typically occurs in elderly patients, with very few cases reported in children. Here, we present a 12-year-old female patient with childhood-onset oral and genital MMP, clinically suspected to be lichen sclerosus, but eventually diagnosed as MMP after multiple supportive biopsies and confirmatory direct immunofluorescence. Although treatment was challenging, the combined use of systemic corticosteroids, dapsone, and mycophenolate mofetil was ultimately successful in achieving disease control.

Consult and procedure incidence outcomes following establishment of a fertility preservation program for children with cancer.

PURPOSE: Fertility is a quality of life outcome adversely affected by cancer therapy. Many childhood cancer patients, however, are not offered options to preserve their fertility. Providers acknowledge difficulty discussing impaired fertility to patients due to lack of knowledge of available options. Our objective was to review the impact of a pediatric multidisciplinary fertility preservation program on providers' fertility preservation counseling and discussion of options. METHODS: A retrospective medical chart review was conducted for pediatric cancer patients prior to and following program establishment. Fertility preservation discussions, consults, and incidence were noted. Following filtering and stratification, 198 and 237 patients were seen prior to and following program establishment, respectively. RESULTS: Following program establishment, provider-patient discussions of impaired fertility (p = 0.007), fertility preservation consults (p = 0.01), and incidence of fertility preservation procedures (p < 0.001) increased among patients. Furthermore, the number of patients who received fertility preservation consults after receiving gonadotoxic treatment decreased (p < 0.001). This trend was particularly noted in pre-pubertal and female patients, for whom fertility preservation options are limited without an established program. CONCLUSION: The establishment of a formal program greatly improved access to fertility preservation consults and procedures in children with cancer.

Eating, sleeping and sexual function disorders in women with polycystic ovary syndrome (PCOS): A systematic review and meta-analysis.

PURPOSE: We aim to evaluate the association of PCOS with eating, sleeping and sexual function disorders. METHODS: A comprehensive search including MEDLINE, Embase, Cochrane Central Register of Controlled Trials, Cochrane Database of Systematic Reviews, and Scopus through 01 August 2018 was conducted for studies reporting the prevalence of any eating, sleep or sexual function disorders in patients with PCOS. Independent reviewers selected studies and extracted data. A random-effects model was utilized to generate pooled odds ratio (OR) and 95% confidence intervals (CI) for binary outcomes, and mean difference (MD) and 95% CI for continuous outcomes. RESULTS: We included 36 studies reporting on 349,529 patients. Compared to women without PCOS, women with PCOS were more likely to have bulimia nervosa (OR 1.37; %CI, 1.17 to 1.60), binge eating (OR 2.95; 95%CI, 1.61 to 5.42), or any eating disorder (OR 1.96; 95% CI 1.18 to 3.24); but not anorexia nervosa (OR 0.92; 95%CI, 0.78 to 1.10). Women with PCOS were more likely to have sleep disorders like hypersomnia (OR 4.39; %CI, 1.07 to 18.07) and obstructive sleep apnoea (OR 10.81; %CI, 2.39 to 48.83). Women with PCOS had lower sexual satisfaction as measured on a visual analogue scale (MD -29.67; 95% CI, -36.97 to -22.37), but no difference in Total Female Sexual Function Index (MD -0.06; 95% CI, -0.51 to 0.38). CONCLUSION: PCOS can be associated with an increased risk of eating and sleeping disorders as well as decreased sexual satisfaction. Screening for these disorders in women with PCOS may allow early intervention and improve quality of life.

Is There a Difference in Hirsutism Score in Adolescents with Polycystic Ovary Syndrome on the Basis of Ethnicity and Race?

BACKGROUND: The complex correlation between ethnicity and race, clinical hyperandrogenism as signified by hirsutism, and biochemical androgen concentrations in polycystic ovary syndrome (PCOS) is poorly understood. STUDY OBJECTIVE: The aim of this study was to define the correlation between ethnicity/race and hirsutism score in patients with PCOS. METHODS: We conducted a retrospective chart review of a total of 251 patients with PCOS at the time of diagnosis. Patients were categorized by their ethnicity and race into 5 main groups: Asian (n = 19, 7.6%), Black or African American (n = 11, 4.4%), Hispanic or Latino (n = 26, 10.3%), White (n = 177, 70.5), and others (n = 18, 7.2%). A general linear model was applied using BlueSky software. RESULTS: For the entire study population, the mean age at diagnosis was 15.6 ± 1.7, the mean body mass index (BMI) was 30.6 ± 9.8, the mean hirsutism score using the modified Ferriman-Gallwey score chart was 6.2 ± 3.8, and the mean total testosterone was 40.1 ± 20. The hirsutism score was the highest in the Asian population (mean = 9.1, P = .002) and Hispanic or Latino population (mean = 7.8, P = .02), followed by others (mean = 7.4, P = .04) and the Black or African American population (mean = 7.1, P = .2), compared with the White population (mean = 5.4). This correlation remained significant despite accounting for BMI and androgen levels (P < .001). CONCLUSION: There are factors likely related to hair follicle sensitivity or endogenous response to circulating free androgens that differ between ethnicities and races, such that similar biochemical concentrations lead to differing severity of hirsutism, despite accounting for differences in BMI and androgen levels. More research is needed in this realm to understand the pathophysiologic basis of this interaction.

The Importance of Fertility Preservation in the Transgender Population.

OBJECTIVE: To call to attention the often-overlooked aspect of pediatric transgender care: the importance of fertility preservation prior to instituting gender-affirming therapy. The transgender population has long been marginalized by society. Societal stigmata, fear to seek care, and dearth of provider knowledge regarding transgender health issues have caused disparities to widen. Gender-affirming procedures and hormone therapy affect the long-term reproductive potential of transgender individuals. While cost concerns and insurance coverage regarding oncofertility is a prominent area of discussion, the transgender community is often excluded. METHODS: Sixteen genetically XY females, followed by their multidisciplinary transgender care teams, were interested in starting hormone therapy due to impending onset and/or progression of puberty. Their physicians were aware of fertility struggles after undergoing hormone therapy and therefore referred to urology. Sperm cryopreservation via open gonadal biopsy, testicular tissue cryopreservation (TTC), and semen sample (when age/maturity-appropriate) were discussed. Though requiring surgery, biopsy/TTC relieves patients of the psychological impact of semen sample production. RESULTS: Under IRB approval, 15 patients (median age 12 years, range 10-16 years) underwent TTC (Fig. 1). One patient (aged years) opted for semen sample. All patients had success with spermatogonial stem cells cryopreserved for future patient use. CONCLUSION: With more individuals beginning medical and surgical therapy at a younger age, fertility preservation discussions are essential but often overlooked, depriving these individuals the joy of becoming a biological parent. TTC can be safely done in pediatric populations, though research is necessary to expand beyond current experimental stage of tissue development.

Puberty Blocker and Aging Impact on Testicular Cell States and Function.

Spermatogonial stem cell (SSC) acquisition of meiotogenetic state during puberty to produce genetically diverse gametes is blocked by drugs collectively referred as 'puberty blocker' (PB). Investigating the impact of PB on juvenile SSC state and function is challenging due to limited tissue access and clinical data. Herein, we report largest clinically annotated juvenile testicular biorepository with all children with gender dysphoria on chronic PB treatment highlighting shift in pediatric patient demography in US. At the tissue level, we report mild-to-severe sex gland atrophy in PB treated children. We developed most extensive integrated single-cell RNA dataset to date (>100K single cells; 25 patients), merging both public and novel (52 month PB-treated) datasets, alongside innovative computational approach tailed for germ cells and evaluated the impact of PB and aging on SSC. We report novel constitutional ranges for each testicular cell type across the entire age spectrum, distinct effects of treatments on prepubertal vs adult SSC, presence of spermatogenic epithelial cells exhibiting post-meiotic-state, irrespective of age, puberty status, or PB treatment. Further, we defined distinct effects of PB and aging on testicular cell lineage composition, and SSC meiotogenetic state and function. Using single cell data from prepubertal and young adult, we were able to accurately predict sexual maturity based both on overall cell type proportions, as well as on gene expression patterns within each major cell type. Applying these models to a PB-treated patient that they appeared pre-pubertal across the entire tissue. This combined with the noted gland atrophy and abnormalities from the histology data raise a potential concern regarding the complete 'reversibility' and reproductive fitness of SSC. The biorepository, data, and research approach presented in this study provide unique opportunity to explore the impact of PB on testicular reproductive health.

Risk reduction for small cell cancer of the ovary, hypercalcemic type in prepubertal patient: A clinical and bioethical perspective.

Loss of heterozygosity in the SMARCA4 gene is a hallmark feature of small cell carcinoma of the ovary, hypercalcemic type (SCCOHT), an aggressive ovarian cancer occurring in young adults and adolescents with an average age of 23 years and a median survival of less than fifteen months following diagnosis. Patients with germline pathogenic variants of SMARCA4 have a genetic predisposition to developing this aggressive ovarian cancer, a condition called rhabdoid tumor predisposition syndrome type 2 (RTPS2). Given the limited efficacy of surveillance imaging for ovarian neoplasm and the absence of an identified biomarker for the progression of this disease, asymptomatic patients who are found to possess pathogenic variants of the SMARCA4 gene following genetic testing are advised to consider risk-reducing bilateral salpingo-oophorectomy to eliminate the risk of SCCOHT. Given the reproductive impacts of this procedure, bioethical consultation must be considered when counseling patients with RTPS2, particularly for those who have not completed their desired course of family planning. In this report, we describe the bioethical considerations and outcomes for the case of a 6-year-old female with a pathogenic variant of SMARCA4 who underwent risk-reducing bilateral salpingo-oophorectomy (RRBSO). To our knowledge, this is the first time that this procedure has been reported in a prepubertal individual for cancer prevention in a patient with RTPS2.

Evaluation of Children with Malignancies for Blood and Marrow Transplantation: A Report from the ASTCT Committee on Practice Guidelines.

Evaluation of a candidate for hematopoietic cell transplantation (HCT) is a complex process with substantial intercenter variability. Although literature providing guidance for evaluating the eligibility of adults is well established, similar guidance for children is lacking. To address gaps between adult recommendations and the specific needs of children, we convened a panel of pediatric HCT experts from a wide geographic range of American Society of Transplantation and Cellular Therapy (ASTCT) member institutions to offer recommendations for pediatric-focused pre-HCT evaluation. In this report from the ASTCT Committee on Practice Guidelines, we present a practical framework for evaluating children with malignancies who are candidates for HCT. We also highlight key differences from adults and emphasize areas of unmet need that require additional research to delineate best practices.

Fertility Preservation: A Tale of Two Testicles.

OBJECTIVE: The transgender population has long been marginalized by society. Societal stigmata, fear to seek care, and dearth of provider knowledge regarding transgender health issues has caused disparities to widen. The purpose of this case study is to call to attention the often-overlooked aspect of transgender care: the importance of fertility preservation prior to undergoing therapy. METHODS: 13 and 16-year old genetically XY patients presented to a tertiary care facility for gender affirmation. Both self-identified as female since a young age and successfully socially transitioned. Impending onset and/or progression of puberty prompted patients to seek hormonal therapy. Fortunately, physicians in transgender clinic were aware of fertility struggles after undergoing hormone therapy and referred for consultation. RESULTS: Sperm cryopreservation via open gonadal biopsy, tissue cryopreservation, and semen sample were discussed. Though invasive, biopsy relieves patients of the psychological impact of sample production and is indicated in pubertal immaturity. After further discussion with patients and parents, the 13-year-old decided to undergo testicular biopsy while the 16-year old opted for semen sample. Both patients had success and their genetic material was cryopreserved for future assisted reproduction. CONCLUSION: Gender affirming procedures and hormone therapy affect the long-term reproductive potential of transgender individuals. While cost concerns and insurance coverage regarding oncofertility is a prominent area of discussion, the transgender community is often excluded. With more individuals beginning medical and surgical therapy at a younger age, fertility preservation discussions are essential but often overlooked, depriving these individuals the joy of becoming a biological parent.

Ovarian Steroid Cell Tumor Masquerading as Steroid-Unresponsive Congenital Adrenal Hyperplasia.

OBJECTIVE: Ovarian neoplasms in children are rare. The objective of this report is to emphasize the importance of considering those neoplasms in the differential diagnosis of hyperandrogenism even with negative diagnostic imaging. METHODS: We report the case of a 12-year-old girl who presented with virilization and elevated 17 hydroxyprogesterone (17-OHP) and who was subsequently diagnosed with an ovarian neoplasm. RESULTS: The patient was initially seen for hirsutism and deepening of the voice. Elevated 17-OHP, androstenedione, and testosterone prompted the initial diagnosis of nonclassic congenital adrenal hyperplasia due to 21-hydroxylase deficiency, but those levels failed to suppress on corticosteroid therapy. Ultrasound, computed tomography scan, and magnetic resonance imaging of the abdomen and pelvis were normal. Genetic testing for congenital adrenal hyperplasia was negative. Bilateral selective adrenal and ovarian venous sampling confirmed the ovarian origin of her hyperandrogenism. A unilateral salpingo-oophorectomy revealed a steroid cell tumor. Postoperatively there was normalization of testosterone and 17-OHP. CONCLUSION: This report highlights the utility of selective adrenal and ovarian sampling when suspecting a primary androgen-secreting neoplasm, even in the setting of elevated 17-OHP levels and negative imaging studies, as early diagnosis can prevent manifestation of irreversible symptoms of virilization.

Establishment of a Pediatric Ovarian and Testicular Cryopreservation Program for Malignant and Non-Malignant Conditions: The Mayo Clinic Experience.

STUDY OBJECTIVES: To describe the structure of a pediatric fertility preservation (FP) program and to share safety and patient satisfaction data. DESIGN: The FP program operates under prospective research protocols approved by the Mayo Clinic Institutional Review Board (IRB). SETTING: The FP program is a multidisciplinary effort between pediatric gynecology, reproductive endocrinology, pediatric urology, pediatric surgery, and laboratory medicine. PARTICIPANTS: The FP program enrolls patients between 0-17 years of age who have been diagnosed with a fertility-threatening condition and/or are scheduled to undergo gonadotoxic treatment. INTERVENTIONS: FP is offered in the form of ovarian tissue cryopreservation (OTC) and testicular (TTC) tissue cryopreservation. MAIN OUTCOME MEASURES: The outcome measures are the safety of the procedure and results of patient surveys conducted by phone using a standard list of questions to assess attitudes towards FP. RESULTS: To date, we have enrolled 38 OTC and 37 TTC patients. The median age (range) of OTC and TTC patients was 11 years (0.83-17 years) and 10 years (0.92-17 years) at the time of enrollment, respectively. Childhood cancers currently represent 88% of the fertility-threatening diagnoses. Meanwhile, patients with non-malignant conditions include those with gender dysphoria, aplastic anemia, and Turner's syndrome. To date, no serious adverse events (SAEs) have been reported following surgery. According to n = 34 one-year follow-ups, 100% of parents felt that FP was a good decision. CONCLUSION: Consistent with the literature, our data suggests FP is safe and improves the quality of care provided to pediatric patients for their fertility-threatening diagnoses and/or treatments. TRIAL REGISTRATION: NCT02872532, NCT02646384.
