Abstract
OBJECTIVES Pseudohypoparathyroidism (PHP1B) is most commonly caused by epigenetic defects resulting in loss of methylation at the GNAS locus, although deletions of STX16 leading to GNAS methylation abnormalities have been previously reported. The phenotype of this disorder is variable and can include hormonal resistances and severe infantile obesity with hyperphagia. A possible time relationship between the onset of obesity and endocrinopathies has been previously reported but remains unclear. Understanding of the condition's natural history is limited, partly due to a scarcity of literature, especially in children. CASE PRESENTATION We report three siblings with autosomal dominant PHP1B caused by a deletion in STX16 who presented with early childhood onset PTH-resistance with normocalcemia with a progressive nature, accompanied by TSH-resistance and severe infantile obesity with hyperphagia in some, not all of the affected individuals. CONCLUSIONS PHP1B from a STX16 deletion displays intrafamilial phenotypic variation. It is a novel cause of severe infantile obesity, which is not typically included in commercially available gene panels but must be considered in the genetic work-up. Finally, it does not seem to have a clear time relationship between the onset of obesity and hormonal resistance.

Abstract
Screening for congenital adrenal hyperplasia (CAH) remains heterogenous across geographies-we sought to determine the proportion of non-classical CAH (NCAH) detection by one vs. two newborn screens (NBS) in two U.S. regions. Data were collected at tertiary centers in Houston (HOU) and Los Angeles (LA) on 35 patients with NCAH, comparing patients identified via the NBS vs. during childhood, 17-hydroxyprogesterone (17-OHP) levels, genotype, and phenotype. The NBS filter-paper 17-OHP levels and daily cutoffs were recorded on initial and second screens. In all, 53% of patients with NCAH in the HOU cohort were identified as infants via the second NBS. Patients identified clinically later in childhood presented at a similar age (HOU: n = 9, 5.5 ± 3.1 years; LA: n = 18, 7.9 ± 4 years) with premature pubarche in almost all. Patients in LA had more virilized phenotypes involving clitoromegaly and precocious puberty and were older at treatment onset compared with those identified in HOU by the second NBS (HOU: 3.2 ± 3.9 years; LA: 7.9 ± 4.0 years, p = 0.02). We conclude that the early detection of NCAH could prevent hyperandrogenism and its adverse consequences, with half of the cases in HOU detected via a second NBS. Further studies of genotyping and costs are merited.

Abstract
BACKGROUND Our purpose is to describe the structure, function and outcomes of our multidisciplinary pediatric thyroid program and to evaluate our experience in comparison to other high-volume centers. METHODS We reviewed all thyroid operations performed 10/2012 through 09/2019, and examined number of cases per year, patient demographics, procedures, final diagnoses and results. Primary outcomes were hypoparathyroidism and recurrent laryngeal nerve (RLN) injury at 12 months. Data were analyzed using descriptive statistics and univariate analyses. RESULTS We performed 294 thyroid operations on 279 patients. Seventy-nine percent were female. Median age was 15 years (IQR: 12-17). Operations included total thyroidectomy (65%), lobectomy (30%) and completion thyroidectomy (5%). Most common diagnoses were Graves' disease (35%), malignancy (29%), and benign nodule (20%). We developed an evidence-based clinical pathway and conducted weekly multidisciplinary meetings. A clinical data specialist reviewed process and outcome measures routinely. Overall, 6 patients (2.0%) had hypoparathyroidism and 2 (0.7%) had unilateral RLN injury at 12 months. Two of the patients with clinical suspicion of permanent hypoparathyroidism were ultimately weaned off calcium. Both patients with RLN injury had extensive locally advanced malignant disease involving the nerve. CONCLUSIONS Our multidisciplinary team achieved excellent long-term outcomes for pediatric thyroid surgery comparable to other high-volume pediatric and adult centers.

Abstract
In 1965, a botched circumcision left Bruce Reimer, a healthy, 8-month old XY male, with a disfigured penis. At the recommendation of Dr. John Money and physicians at Johns Hopkins, the infant was reassigned to female sex and underwent an orchiectomy and vaginoplasty. The family renamed the child “Brenda.” Unaware of her history, Brenda struggled with significant gender identity, psychological, and behavioral issues throughout her childhood and adolescence. When made aware of this history, she transitioned to male gender and assumed the name “David.” After years of psychological distress, David Reimer committed suicide in 2004. Despite the myriad lessons gleaned from this tragic story, medical and surgical management of children with atypical genitalia still remains often misguided, as providers continue to assume paternalistic roles in determining sex assignment and surgical interventions. A fifteen year old XY male with Robinow Syndrome presented for evaluation of hypogonadism and urinary incontinence. At birth, the patient was discovered to have a micropenis and perineal hypospadias and was diagnosed with hypogonadotropic hypogonadism. At the recommendation of the medical team, the infant underwent bilateral orchiectomy at eight months of age followed by urethroplasty and vaginoplasty at six years of age. The child was then given a female sex assignment. At twelve years of age, the child felt discordant from the sex of rearing and wished to be identified as male—his natal, genetic sex. He transitioned to male gender and began testosterone injections. He had history of recurrent UTIs and severe incontinence requiring diaper use. He strongly desired neophallus and urethral reconstruction for improved quality of life. The patient endorsed prior depression and desires to self-harm. He had significant concerns regarding his gender presentation and transition. He shared his difficulties in continuing in the same school system with peers who knew him as a female prior to transition and was concerned about peers knowing his medical history. In the years since the famous David Reimer case, the medical system has made tremendous strides in recognizing the need for patient autonomy and shared decision-making in patients with Differences of Sex Development and genital atypia. However, the paternalistic history of this field continues to leave its indelible mark more than 20 years since David Reimer’s case made headlines, as physicians continue to recommend definitive sex assignments and surgical interventions. As with the David Reimer case, the bodily integrity of this XY infant was altered in a permanent fashion with inadequate education of his family and little to no credence given to the autonomy of the child himself. We, as physicians, cannot continue to paternalistically apply John Money’s concept of gender neutrality and rigidly mandate sex assignments and early surgical interventions.

Abstract
Maffucci syndrome is a rare disorder characterized by enchondromatosis and hemangiomata. It can occur due to sporadic, de novo, mosaic pathogenic variants in the gene encoding isocitrate dehydrogenase 1 (IDH1) or isocitrate dehydrogenase 2 (IDH2). IDH1 variants are associated with endocrine manifestations, such as pituitary adenomas. However, literature is limited in describing other clinical features and available treatments in severe phenotypes. We report a pediatric patient with uniquely complex and severe Maffucci syndrome. Case: A 5-year-old boy was evaluated by pediatric endocrinology for chronic hypercalcemia as part of a multidisciplinary evaluation of his severe Maffucci syndrome. Past medical history included prematurity, restrictive lung disease, developmental delay, seizures, 2-OH glutaric aciduria, angiomas, and bicytopenia. Physical exam revealed angiomas, scoliosis, and severe bony deformities throughout the entire skeleton. During admission, laboratory assays revealed normal parathyroid hormone, phosphorus, 1,25-OH2D, and C-telopeptide; elevated serum calcium and PTH-related peptide; and low 25-OHD, alkaline phosphatase, and osteocalcin. Low-dose ACTH stimulation test yielded a peak cortisol level of 16.8. A 24-hour urine study confirmed hypercalciuria. Renal ultrasound demonstrated nephrocalcinosis. Skeletal survey revealed diffuse and chondromatous changes of nearly every bone. Whole-exome sequencing detected a presumed, mosaic de novo IDH1 variant. DEXA scan revealed total body BMD z-score of -3.8. Discussion: Hypercalcemia in Maffucci syndrome is a rare phenomenon. The most likely etiology was due to the severe and chronic bony breakdown from the underlying progressive enchondromatosis. Subsequently, the body attempted to adapt to these chronic processes with abnormal mineral homeostasis, as seen in his laboratory assays. Chronic primary hyperparathyroidism was not likely, as his PTH, phosphorus, and 1,25 OH2D levels were not congruent with that diagnosis. Familial hypocalciuric hypercalcemia was not likely, as his urine calcium clearance ratio was >0.01. Finally, his slightly elevated PTHrP level was not due to PTHrP-mediated hypercalcemia of malignancy, as his bone marrow biopsy was negative. The options for short-term hypercalcemia management had their own inherent risks and were not suitable for long-term management. Although there is a lack of pediatric data to guide therapy in Maffucci syndrome, decision was made to proceed with bisphosphonate infusion given the benefits in the setting of his nephrocalcinosis, chronic hypercalcemia, and results of his DEXA scan. Given the rarity of Maffucci syndrome, few characteristics are well-described in the pediatric population. A multidisciplinary approach is necessary to review the severity of the disease and to determine the best treatment approach based on this information.

Abstract
Background: We evaluated the feasibility and acceptability of a pilot behavioral intervention delivered to parents of adolescents with type 1 diabetes (T1D) via mobile-friendly web app. The Type 1 Doing Well app aimed to promote supportive family diabetes management by helping parents recognize and reinforce teens' positive diabetes-related behaviors ("strengths"). Methods: Parents (n = 80, 74% recruitment) of adolescents (age range = 12-17 years, M = 15.3 ± 1.5 years, 59% female, 56% insulin pump, M hemoglobin A1c (HbA1c) = 9.0% ± 2.1%) were randomized 2:1 to intervention or control (i.e., usual medical care with or without app) for 3-4 months between diabetes appointments. The app prompted parents daily to track adolescents' strengths and generated weekly summaries of their teen's top strengths. Parents could access a library of text messages to praise their teens. Exploratory pre/post data included questionnaires (98% completed) and HbA1c. Results: Parents used the app for M = 106.1 ± 37.1 days, logging in ≥once/day on 80% of days. Ninety-one percent of parents used the app ≥2 days/week on average. Parents viewed M = 5.6 ± 4.7 weekly summaries and "favorited" 15 praise texts in the library. App acceptability ratings (7-point scale) were high: Satisfaction 5.0 ± 1.5, Usefulness 4.8 ± 1.5, Ease of Use 6.2 ± 0.8, and Ease of Learning 6.5 ± 0.8. Parents (n = 48) and adolescents (n = 47) gave positive feedback and suggestions via qualitative interviews. There were no significant between-group differences for change in exploratory outcomes (HbA1c, questionnaires). Conclusions: Type 1 Doing Well was feasible to deliver and highly acceptable and engaging for parents of adolescents with T1D. It may have a larger impact on behavioral or clinical outcomes as part of a multicomponent intervention protocol. Trial Registration: ClinicalTrials.gov NCT02877680.

Abstract
Background. Gonadotropin therapy is not typically used for pubertal induction in hypogonadotropic hypogonadism (HH), however, represents a promising alternative to testosterone. It can potentially lead to the maintenance of future fertility in addition to testicular growth. We compared the pubertal effects of human chorionic gonadotropin (hCG) versus testosterone in adolescent males with HH. We evaluated the current practice, among pediatric endocrinologists, to identify barriers against gonadotropin use. Methods. In this retrospective review, we compared the effect of testosterone versus hCG therapy on mean testicular volume (MTV), penile length, growth velocity, and testosterone levels. We surveyed pediatric endocrinologists at our center, using RedCap. Results. Outcomes were assessed in 52 male patients with HH (hCG, n = 4; T, n = 48) after a mean treatment duration of 13.4 (testosterone) and 13.8 months (hCG; P = .79). Final MTV was higher with hCG (8.25 mL) than testosterone (3.4 mL; P < .001). The groups did not differ in penile length, growth velocity, or testosterone levels. Survey results showed that more than half the providers were aware of the benefits of gonadotropins, however, 91% were uncomfortable prescribing hCG. Commonly reported barriers to prescribing hCG were lack of experience (62%) and insurance coverage concerns (52%). Conclusions. Larger testicular volume predicts faster induction of spermatogenesis. Since hCG promoted better testicular growth, compared to testosterone, it may potentially improve future fertility outcomes in HH patients. Our results identify an opportunity to improve current practice among pediatric endocrinologists worldwide and reduce barriers to prescribing gonadotropins in the adolescent population.

Abstract
Introduction: Clitoromegaly presenting in childhood can be congenital or acquired. The most common cause is exposure to excess androgens in fetal or neonatal life. However, non-hormonal causes like neurofibromatosis type 1 (NF-1), epidermoid cysts, tumor syndromes have been reported. An asymmetric or irregular appearing clitoris is usually caused by a non-hormonal process. Clinical Case: A 6-year-old female with NF-1 and right-sided hemihypertrophy was referred to endocrinology due to progressive clitoromegaly since birth. NF-1 features included café-au-lait spots, bilateral optic nerve gliomas, plexiform neurofibroma, Lisch nodule, first degree relatives with NF-1 (sister and mother). At age 1.5, a hormonal work up was negative for hyperandrogenism. At age 2, patient was seen by genetics, and by urology for removal of a bladder neurofibroma, but did not return to these specialties for follow up. Lumbar spine MRI, obtained for back pain, revealed a large sciatic plexiform neurofibroma. She followed with oncology for cancer surveillance and due to parental concern for progressive clitoromegaly was referred to endocrinology at age 6. At the endocrinology visit, parents denied breast development, vaginal discharge or bleeding, axillary or pubic hair, body odor or acne. Her genital exam revealed a clitoris 3 x 1.5 cm in size, Tanner 1 pubic hair, no palpable gonads, no labial fusion but asymmetric labial sizes (right>left). A hormonal workup was normal including 41 ng/dL 17-hydroxyprogesterone (n ≤137 ng/dL), 20 ng/dL androstenedione (n ≤ 45 ng/dl), 42 ng/dL unconjugated DHEA (n ≤ 487 ng/dL), 11 mcg/dL DHEA Sulfate (n ≤ 34 mcg/dL), 3 ng/dL total testosterone (n ≤ 21 ng/dL) and pre-pubertal LH, FSH and estradiol levels. Patient was referred to a multi-disciplinary DSD (Disorders of Sexual Differentiation) clinic for further evaluation and potential surgical options. A pelvic ultrasound and subsequent pelvic MRI revealed that the large sciatic plexiform neurofibroma, detected on the prior MRI, had now extended into the clitoris and right labia. Uterus and ovaries were pre-pubertal in size. Surgical options were discussed in a multi-disciplinary approach. Since clitoral enlargement was contiguous with posterior bladder mass and vital organ functions were not affected, resection was not recommended. Clitoral reduction for cosmetic reasons had a potential risk of recurrence. Since benefits did not outweigh the risks, family chose to not pursue any surgical intervention. Conclusions: NF-1 is a rare but potential non-hormonal cause of clitoromegaly. In the absence of clinical evidence of hyperandrogenism, clitoromegaly in a patient with NF-1 does not warrant an extensive hormonal work up. Pelvic imaging should be pursued first, to search for local neurofibromas. Decision for surgical interventions requires a multi-disciplinary approach with detailed discussion of benefits vs. risks.

Abstract
Background: XY gonadal dysgenesis is characterized by the presence of male chromosomes with atypical testes differentiation. Due to an impaired ability to make testosterone, patients are often under-virilized at birth and present with ambiguous genitalia. For multidisciplinary teams specialized in disorders of sex development (DSD), gonadal dysgenesis presents challenges in sex assignment, initiation of hormonal therapy, and timing of surgical interventions. Recent discussions have reconsidered early interventions in favor of preserving self-determination in decisions regarding gender and anatomy. Case: LT initially presented at 3 years old, after her grandmother noted her abnormal appearing genitalia. Examination revealed clitoromegaly, 1.8 cm in length and 0.8 cm in width, with a blind, open introitus. XY gonadal dysgenesis was diagnosed, based on a pelvic MRI, cystourtheroscopy/vaginoscopy, genetic and hormonal testing. LT was lost to follow-up for 6 years. At 11 years old, LT had been consistently raised as a female. When asked about gender identity, LT’s understanding of gender identity developed over time. At 11 years old, LT declared her gender identity as a “boy”, because boys are “strong”, and because she did not like make-up. LT denied any desire for breast development and explained that her family told her that breasts ‘make it hard to run fast.’ On follow-up evaluation 6 months later, LT voiced her decision to be a girl, and said that she was very confident in this decision. LT and her parents both desired estrogen therapy for induction of puberty. After discussions regarding the permanent effects of therapy, LT started hormone therapy. Two months after initiation of therapy, she remained firm in her gender identity and expressed a desire to grow her hair long. She independently stated that she did not desire surgery at this time. She will receive formal psychological testing at her next clinical evaluation to evaluate her for body dysmorphia, anxiety, and depression. Discussion LT’s case demonstrates the progression of developmental understanding of gender and expressed gender identity that may occur as learning progresses in patients with DSDs. This case also shows that a delay in surgery may not have significant developmental consequences to these patients as was previously suggested. In general, the American medical system has tended to perform early sex assignments and surgical interventions to align anatomy with the sex assignment. However, after thoughtful discussions regarding human rights concerns, many have recommended to delay surgical interventions until adolescence, when the patient can consent appropriately to interventions that cause permanent anatomic changes. As many of these interventions may be discussed in early adolescence, it is of the utmost importance that information is presented in an understandable and developmentally appropriate manner.

Abstract
Abstract
Background: The use of gonadotropins is a recent strategy for inducing puberty in adolescent males with hypogonadotropic hypogonadism (HH). Testosterone use has been discouraged in patients who desire to preserve fertility. Human chorionic gonadotropin (hCG) has been recommended for inducing puberty in HH; however, several clinicians administer hCG in combination with other gonadotropins. The benefits of using combination gonadotropin therapies (hCG+) over hCG monotherapy in pre-pubertal adolescent males with HH has not been clearly established. We performed a meta-analysis to assess the outcomes of hCG compared to hCG+ in terms of virilizing effects and testicular growth in peripubertal boys with HH.
Methods: We evaluated for heterogeneity among studies. We calculated pooled means for the post-treatment mean testicular volume (MTV), testosterone (T) level, and penile length for the hCG monotherapy and hCG+ treatment groups. We performed a meta-regression analysis to examine the contribution of various factors to post-treatment outcomes including baseline T level, age, treatment duration, and study quality.
Results: The meta-analysis included seven studies. All participants were prepubertal (age range: 13.3–25.9 years), with weighted mean treatment durations of 10.95 months for hCG monotherapy and 28.2 months for hCG. There was significant heterogeneity in baseline age (Q = 121.71; df = 1; P < 0.001) and T levels (Q = 436.74; df = 1; P < 0.001) between the two treatment groups. The hCG+ group had a larger post-treatment MTV, but it was not significantly different between the two groups (6.60 mL [95% CI, 3.18–10.02] for hCG monotherapy vs. 10.02 mL [95% CI, 8.30–11.75] for hCG+; P = 0.079). Post-treatment T levels differed significantly between the two groups (101.89 ng/dL [95% CI, 50.7–153.08] for hCG monotherapy vs. 424.10 ng/dL [95% CI, 304.59–543.62] for hCG+; P < 0.0001). A meta-regression analysis of post-treatment T levels showed that baseline age, baseline T level, and study grade did not contribute significantly to the difference between treatment groups. Treatment duration explained 3.04% of the difference between the two groups (P < 0.0001). After adjusting for treatment duration, the post-treatment T level remained significantly higher in the hCG+ group compared to the hCG monotherapy group. The hCG+ was also associated with better outcomes for post-treatment penile length, although these findings relied on data from only three studies.
Conclusion: Our study indicates that hCG+ therapies provide potential benefits over hCG monotherapy for pubertal induction in males with HH, regarding T levels and penile growth, with no difference in testicular growth between treatments. Prospective pediatric studies are needed to assess the benefits of these therapies in patients with HH and, ultimately, to establish guidelines for gonadotropin therapy in the adolescent population.

Abstract
Background: Normative data for clitoral size in premature infants are limited. Consequently, the potential for over-diagnosis is high; leading to unnecessary investigations, increased healthcare costs and parental stress. Several proposed mechanisms, e.g., persistence of fetal adrenal zone activity to term gestation, point to the transient physiologic nature of clitoromegaly in premature infants. Studies of normative data have shown a negative correlation between birth weight and clitoral size. We hypothesized that 1) the majority of clitoromegaly in premature infants is not associated with hormonal dysfunction and 2) lower birth weight and lower gestational age increase the likelihood of a formal consult in premature infants with perceived clitoromegaly. Methods: A retrospective chart review of female infants born at our institution from January 2012 to December 2018 with perceived clitoromegaly was conducted. Birth history, demographic and laboratory data were collected. Patients were divided into two groups: ‘formal consult’ and ‘no formal consult’ for clitoromegaly. True clitoromegaly was defined as clitoral length >9 mm or clitoral width >6 mm. Patients not meeting these criteria or those with clitoral edema, prominent clitoral hood were classified under false clitoromegaly. In the ‘no formal consult’ group, the documented discharge examination was used to assess persistence of clitoromegaly. Uni- and multi-variable logistic regression were used to determine factors that increased the likelihood of a formal consult. Results: 29 patients met inclusion criteria; 15 in the ‘formal consult’ group and 14 in the ‘no formal consult’ group. No significant differences were found between the groups in terms of birth weight, gestational age, race, ethnicity and maternal factors. History of IUGR (intrauterine growth restriction) was more common in the ‘formal consult’ group (60%) vs. ‘no formal consult’ group (21%) (p=0.04). Only 3/15 patients in the ‘formal consult’ group had true clitoromegaly; all 3 had normal 17-hydroxyprogesterone levels, and only 1 patient had transient elevation in androgen levels (androstenedione, deoxycortisol and testosterone). Of the ‘no formal consult’ group, only 3/14 patients had clitoromegaly noted on discharge; outcome was unknown for 1. Multi-variable logistic regression showed that lower gestational age (p=0.04) and history of IUGR (p=0.03), even after adjusting for birth weight, increased the likelihood of a formal consult. Conclusion: In summary, the majority of perceived clitoromegaly in premature infants is not associated with hormonal dysfunction. Lower gestational age and a history of IUGR increase the likelihood of a formal consult for clitoromegaly in these patients. Approximately half of the patients were noted to have false clitoromegaly indicating inconsistencies in examination technique and need for provider education.

Abstract
BACKGROUND Hypospadias is a common genitourinary malformation and there are conflicting data on whether its prevalence is increasing. Previous studies have described associations with risk factors including small for gestational age (SGA), multiple gestation birth, environmental influences, and maternal factors. OBJECTIVE The objective of this study was to examine birth prevalence of hypospadias and hypospadias risk factors in a large national dataset and to evaluate for changes from 1997 to 2012. We hypothesized that any increase in the birth prevalence of hypospadias would be associated with an increase in risk factors such as SGA, prematurity, or multiple gestation birth. STUDY DESIGN The Kids' Inpatient Database was used to generate national estimates for prevalence of males born with hypospadias, SGA, prematurity, or to a multiple gestation and then prevalences were evaluated for association with time. Multivariable logistic regression was used to evaluate whether birth prevalence of hypospadias was associated with increasing year, SGA, prematurity, and multiple gestation birth. RESULTS The estimated birth prevalence of hypospadias increased from 6.1 per 1000 births (95% confidence interval [CI] 5.9 to 6.3) to 6.8 per 1000 births (95% CI 6.7 to 7.0), an 11.5% increase from 1997-2012 (P = 0.014). Among male births, the prevalence of SGA increased 74%, multiple gestation increased 25%, and prematurity increased 20% (P < 0.001 for all) (Summary Figure). A risk factor was seen in around 20% of males born with hypospadias. Hypospadias birth prevalence also increased in males without risk factors but was not statistically significant (9.1% increase, P = 0.5). On multivariable logistic regression, being born SGA (odds ratio [OR] = 3.3), to a multiple gestation (OR = 1.1), or premature (OR 1.9) were associated with increased odds of hypospadias (P < 0.01 for all), whereas increasing year was not (P = 0.3). CONCLUSIONS The estimated birth prevalence of hypospadias in the United States increased from 6.1 to 6.8 per 1000 births from 1997 to 2012. Known hypospadias risk factors of SGA birth, multiple gestation birth, and premature birth also increased over this time to a higher degree. About 20% of males born with hypospadias had one of these risk factors. The birth prevalence of hypospadias in males without any studied risk factors also increased, but this was not statistically significant. More studies are needed to evaluate whether this increase in hypospadias prevalence is due to increases in known hypospadias risk factors, new environmental exposures, improved diagnosis at birth, some combination, or unrelated causes.

Abstract
Background Supportive parent involvement for adolescents’ type 1 diabetes (T1D) self-management promotes optimal diabetes outcomes. However, family conflict is common and can interfere with collaborative family teamwork. Few interventions have used explicitly strengths-based approaches to help reinforce desired management behaviors and promote positive family interactions around diabetes care. Objective The aim of this protocol was to describe the development of a new, strengths-based behavioral intervention for parents of adolescents with T1D delivered via a mobile-friendly Web app called Type 1 Doing Well. Methods Ten adolescent-parent dyads and 5 diabetes care providers participated in a series of qualitative interviews to inform the design of the app. The 3- to 4-month pilot intervention will involve 82 parents receiving daily prompts to use the app, in which they will mark the diabetes-related strength behaviors (ie, positive attitudes or behaviors related to living with or managing T1D) their teen engaged in that day. Parents will also receive training on how to observe diabetes strengths and how to offer teen-friendly praise via the app. Each week, the app will generate a summary of the teen’s most frequent strengths from the previous week based on parent reports, and parents will be encouraged to praise their teen either in person or from a library of reinforcing text messages (short message service, SMS). Results The major outcomes of this pilot study will include intervention feasibility and satisfaction data. Clinical and behavioral outcomes will include glycemic control, regimen adherence, family relationships and conflict, diabetes burden, and health-related quality of life. Conclusions This strengths-based, mobile health (mHealth) intervention aims to help parents increase their awareness of and efforts to support their adolescents’ engagement in positive diabetes-related behaviors. If efficacious, this intervention has the potential to reduce the risk of family conflict, enhance collaborative family teamwork, and ultimately improve diabetes outcomes.

Abstract
Women with Turner Syndrome (TS) have a variety of medical needs throughout their lives; however, the peripubertal years are particularly challenging. From a medical perspective, the burden of care increases during this time due to growth optimization strategies, frequent health screenings, and puberty induction. Psychologically, girls begin to comprehend the long-term implications of the condition, including their diminished fertility potential. Unfortunately, clear guidelines for how to best approach this stage have not been established. It remains to be determined what is the best age to begin treatment; the best compound, dose, or protocol to induce puberty; how, when or what to discuss regarding fertility and potential fertility preservation options; and how to support them to accept their differences and empower them to take an active role in their care. Given the complexity of this life stage, a multidisciplinary treatment team that includes experts in endocrinology, gynecology, and psychology is optimal.

Abstract
45,X/46,XY gonadal dysgenesis is a disorder of sexual differentiation with a wide clinical presentation, ranging from Turner-like females to individuals with genital ambiguity to azoospermic but otherwise normal-appearing males. Hence, patients can be assigned female or male sex. Female patients are managed according to the Turner Syndrome Guidelines, whereas males are managed on a case-by-case basis. Male patients present with multiple medical challenges: undervirilization, hypogonadism, gonadoblastoma risk, and short stature. Many require surgeries and hormonal treatments that are time-sensitive and irreversible. Nonetheless, these therapeutic decisions are made without evidence-based guidelines. This review describes the medical concerns and possible interventions in male patients with 45,X/46,XY dysgenesis for each stage of development. Interventions should be addressed within a patient-centered framework by a multidisciplinary team and after thorough discussion with the family. We use the GRADE system to appraise the existing evidence and provide recommendations based on the available evidence.

Abstract
Context Cushing Syndrome is difficult to diagnose, and the comorbidities and persistent late effects of hypercortisolemia after treatment of the primary disease are challenging for the patient and the endocrinologist. Objective To report the case of a girl with obesity and hypertension, ultimately diagnosed with Cushing syndrome due to primary pigmented nodular adrenocortical disease. In this case, the complications of hypercortisolism persisted short term despite surgical intervention. Patient A 4 year old morbidly obese African-American girl with developmental delay presented with hypertensive emergency in the ER and 18-month history of progressive weight gain. Her previous history included premature adrenarche, hypertension, seizures and a random high cortisol with suppressed ACTH. She was subsequently stabilized, and a diagnostic work-up persistently demonstrated elevated cortisol and suppressed ACTH. An abdominal MRI showed bilateral adrenal multinodular disease, consistent with multinodular hyperplasia of the adrenal glands. Based on these findings the patient underwent a bilateral adrenalectomy, which confirmed primary pigmented nodular adrenocortical disease. The patient had a complicated, protracted post-operative course requiring adjustment of therapy for persistent hypertension. Two months after surgery, she was readmitted to the Emergency Department with hyperpyrexia and hypertension and succumbed to the complications of sepsis. Conclusions and outcome This case highlights the significant diagnostic and therapeutic challenges in treating children with Cushing syndrome. Resolution of the source of hypercortisolemia does not imply regression of hypertension or recovery of the immune system. Although the child underwent bilateral adrenalectomy, persistent consequences of prolonged severe hypercortisolism contributed to her death two months later.

Abstract
Androgen insensitivity syndrome (AIS) is an undervirilization syndrome in individuals with 46, XY karyotype. The undervirilization can be complete feminization or incomplete virilization with grades of ambiguity. AIS is caused by mutations in the androgen receptor, resulting in resistance to the physiologic activities of androgens. Differing degrees of resistance lead to three phenotypes: a complete form with female-appearing external genitalia, a partial form with a wide range of virilization, and a mild form with only minor undervirilization. AIS presents different challenges depending on whether resistance is complete or partial. Challenges include sex assignment, which impacts other medical decisions such as gonadectomy, hormonal replacement, and other surgical interventions. This review describes medical, psychosocial, and ethical concerns for each stage of development in complete and partial AIS, from the neonatal period to adulthood. These aspects of care should be addressed within an ethical framework by a multidisciplinary team, with the patients and families being the stakeholders in the decision-making process. We use the GRADE system when appropriate to appraise the existing evidence and provide recommendations and guidelines for management of AIS and appropriate transition of patients from pediatric to adult care.

Abstract
DK phocomelia/von Voss Cherstvoy syndrome is a rare condition characterized by upper limb and urogenital abnormalities and various brain anomalies. Previously reported cases have noted significant developmental delays, although no formal testing of cognitive abilities has been reported. In this paper we describe results from a comprehensive neuropsychological evaluation of a 12-year-old male with DK phocomelia syndrome. Test findings indicated mild impairment in intellectual functioning, with more significant impairment in adaptive skills and academic achievement. The neuropsychological profile converged with neurological findings, showing a distinct pattern of strengths and weaknesses that suggests functional compromise of posterior brain regions with relatively well-preserved functioning of more anterior regions. Specifically, impairments were evident in perceptual reasoning, visual perception, and visuomotor integration, whereas normal or near normal functioning was evident in memory, receptive language, social cognition, attention, and most aspects of executive functioning. To our knowledge this is the first report to describe the neurocognitive profile of an individual with DK phocomelia syndrome.

Abstract
CONTEXT Ectopic ACTH/CRH syndrome is a rare cause of Cushing syndrome (CS), especially in children. The localization, work-up, and management of ACTH/CRH-secreting tumors are discussed. SETTING A retrospective study was conducted of patients under 21 years of age evaluated at the National Institutes of Health (NIH) for CS and diagnosed with ectopic ACTH/CRH-secreting tumors during the period 2009-2014. PATIENTS Seven patients with ectopic ACTH/CRH CS are included in this study with a median age 13.6 years (range 1-21), and 3 are female. MEASUREMENTS Clinical, biochemical, radiological features, treatment, and histological findings are described. RESULTS Seven patients were found to have ACTH/CRH-secreting tumors, all with neuroendocrine features. The site of the primary lesion varied: pancreas (3), thymus (2), liver (1), right lower pulmonary lobe (1). PATIENTS underwent biochemical evaluation for CS, including diurnal serum cortisol and ACTH levels, urinary free cortisol levels (UFC), and CRH stimulation tests. All patients underwent radiological investigations including MRI, CT, and PET scan; imaging with octreotide and 68 gallium DOTATATE scans were performed in individual cases. Five patients underwent inferior petrosal sinus sampling; 4 patients had sampling for ACTH and CRH levels from additional sites. Three patients underwent trans-sphenoidal surgery (TSS), and 3 patients required bilateral adrenalectomy. Three patients (43%) died due to metastatic disease, demonstrating the high mortality rate. One of the unique findings in these seven patients is that in each case, their neuroendocrine tumors were ultimately proven to be co-secreting ACTH and CRH. This explains the enigmatic presentation, in which 3 patients initially thought to have Cushing's disease (CD) with corresponding pituitary hyperplasia underwent TSS prior to the correct localization of the causative tumor. CONCLUSIONS Ectopic ACTH/CRH co-secreting tumors are extremely rare in children and adolescents. The diagnosis of this condition is frequently missed and is sometimes confused with CD due to the effect of CRH on the pituitary.

Abstract
Germline nonautoimmune hyperthyroidism due to an activating mutation in the thyroid stimulating hormone receptor gene is an uncommon disease. To date 32 different mutations have been described. The severity of the hyperthyroid symptoms is variable and phenotype differences have been described in subjects harboring the same mutation. This paper describes a family with a mutation in codon 431 of the thyroid stimulating hormone receptor gene. This is the most common activating mutation in the thyroid stimulating hormone receptor gene with total of 13 patients harboring the mutation in four families. The similarities and differences among patients with the mutation in codon 431 are discussed. Furthermore all previously reported activating mutations in the thyroid stimulating hormone receptor gene are reviewed.

Abstract
Hypospadias is one of the most common congenital malformations of the genitourinary tract in males. It is an incomplete fusion of urethral folds early in fetal development and may be associated with other malformations of the genital tract. The etiology is poorly understood and may be hormonal, genetic, or environmental, but most often is idiopathic or multifactorial. Among many possible risk factors identified, of particular importance is low birth weight, which is defined in various ways in the literature. No mechanism has been identified for the association of low birth weight and hypospadias, but some authors propose placental insufficiency as a common inciting factor. Currently, there is no standardized approach for evaluating children with hypospadias in the setting of intrauterine growth restriction. We reviewed the available published literature on the association of hypospadias and growth restriction to determine whether it should be considered a separate entity within the category of disorders of sexual differentiation.

Abstract
Hypospadias is a common congenital malformation in males, the cause of which may be genetic, hormonal, or environmental, although it usually is idiopathic or possibly multifactorial. Determining the optimal diagnostic testing and management remains a challenge. Hypospadias is corrected with surgery, and androgen therapy often is used preoperatively as an adjunctive therapy, although its use, timing, and effectiveness are unclear. No standardized approach has been established for the diagnostic testing for hypospadias or for preoperative androgen therapy. We reviewed current literature and used the Grading of Recommendation, Assessment, Development, and Evaluation (GRADE) system to assess the quality of evidence and provide recommendations for a diagnostic testing algorithm from an endocrine and genetic perspective and for the optimal use of preoperative androgen therapy. These recommendations are an important step towards standardizing the use of diagnostic testing and the management of patients with hypospadias.

Abstract
CONTEXT The overwhelming majority of benign lesions of the adrenal cortex leading to Cushing syndrome are linked to one or another abnormality of the cAMP or protein kinase pathway. PRKAR1A-inactivating mutations are responsible for primary pigmented nodular adrenocortical disease, whereas somatic GNAS activating mutations cause macronodular disease in the context of McCune-Albright syndrome, ACTH-independent macronodular hyperplasia, and, rarely, cortisol-producing adenomas. OBJECTIVE AND DESIGN The whole-genome expression profile (WGEP) of normal (pooled) adrenals, PRKAR1A- (3) and GNAS-mutant (3) was studied. Quantitative RT-PCR and Western blot were used to validate WGEP findings. RESULTS MAPK and p53 signaling pathways were highly overexpressed in all lesions against normal tissue. GNAS-mutant tissues were significantly enriched for extracellular matrix receptor interaction and focal adhesion pathways when compared with PRKAR1A-mutant (fold enrichment 3.5, P < 0.0001 and 2.1, P < 0.002, respectively). NFKB, NFKBIA, and TNFRSF1A were higher in GNAS-mutant tumors (P < 0.05). Genes related to the Wnt signaling pathway (CCND1, CTNNB1, LEF1, LRP5, WISP1, and WNT3) were overexpressed in PRKAR1A-mutant lesions. CONCLUSION WGEP analysis revealed that not all cAMP activation is the same: adrenal lesions harboring PRKAR1A or GNAS mutations share the downstream activation of certain oncogenic signals (such as MAPK and some cell cycle genes) but differ substantially in their effects on others.

Abstract
Germinomas arising in the sella turcica are difficult to differentiate from autoimmune hypophysitis because of similar clinical and pathological features. This differentiation, nevertheless, is critical for patient care due to different treatments of the two diseases. We report the case of an 11-year-old girl who presented with diabetes insipidus and growth retardation, and was found to have an intra- and supra-sellar mass. Initial examination of the pituitary biopsy showed diffuse lymphocytic infiltration of the adenohypophysis and absent placental alkaline phosphatase expression, leading to a diagnosis of hypophysitis and glucocorticoid treatment. Because of the lack of clinical and radiological response, the pituitary specimen was re-examined, revealing this time the presence of scattered c-kit and Oct4 positive germinoma cells. The revised diagnosis prompted the initiation of radiotherapy, which induced disappearance of the pituitary mass. Immunological studies showed that the patient's serum recognized antigens expressed by the patient's own germinoma cells, as well as pituitary antigens like growth hormone and systemic antigens like the Sjögren syndrome antigen B and alpha-enolase. The study first reports the presence of pituitary and systemic antibodies in a patient with intrasellar germinoma, and reminds us that diffuse lymphocytic infiltration of the pituitary gland and pituitary antibodies does not always indicate a diagnosis of autoimmune hypophysitis.

Abstract
We report a unique case of a 3-mo-old female with consumptive hypothyroidism and liver hemangioendothelioma who required pharmacological doses of thyroid hormones and was cured following liver transplantation. Liver hemangioendotheliomas are capable of producing an excess of the thyroid hormone inactivating enzyme, type-3 iodothyronine deiodinase. The increased tumoral enzyme activity leads to rapid degradation of thyroid hormones, resulting in consumptive hypothyroidism. Review of similar cases indicated variable outcomes. We focus on our patient's clinical course and describe in detail the thyroid hormone replacement therapy and a unique outcome of this rare type of hypothyroidism. This first example of a prompt and complete resolution of consumptive hypothyroidism in an infant after liver transplantation confirms the concept and the reversibility of consumptive hypothyroidism and provides novel insights into the rapidity of response of the infant's hypothalamic-pituitary-thyroid axis to thyroid hormone replacement.

Abstract
OBJECTIVE To describe the effects of prolonged maternal treatment with MgSO4 in infants who were products of multiple pregnancies. STUDY DESIGN Case series of infants presenting with osteopenia secondary to MgSO4 administration for preterm labor. RESULTS Ten premature infants with hypermagnesemia (4.5+/-0.2 mg/dl), hypocalcemia (6.0 +/-0.3 mg/dl), and high serum alkaline phosphatase (574+/-96 U/l) underwent imaging studies that showed diffuse osteopenia of the long bones and probable rib fractures. All mothers had isolated premature labor, for which they were given MgSO4; (average dose 3.66+/-0.08 kg/ pregnancy over 10.0+/-0.5 weeks). On follow-up (to 9 months), all infants had complete or near complete resolution of the osteopenia. CONCLUSIONS Premature infants who are exposed to large doses of MgSO4, especially those of multiple pregnancies, have an increased risk of developing hypocalcemia, osteopenia, and fractures. Our findings indicate that these infants should be identified at birth and managed prospectively.

Abstract
We report on a family with familial male-limited precocious puberty (FMPP) due to a D564G mutation of the LHCGR gene. Family members show a varied phenotypic expression from severe precocity unresponsive to therapy with compromise of the predicted final height in some members, to attainment of tall final stature in other members who never received medical treatment. DNA amplification and sequencing of exon 11 of the LHCGR gene was done for the three affected male members and their mother. DNA analysis revealed a D564G mutation in the third cytoplasmic loop of the LHCGR receptor. All three males had precocious puberty with elevated testosterone levels. The index case developed central precocious puberty and evidence of compromised final height while on therapy. In contrast, the untreated older siblings attained a tall final height. This report underscores the possibility that the effects of the mutant luteinizing hormone/choriogonadotropin receptor on phenotypic expression of FMPP, such as adult final height, are modified by other factors.

Abstract
BACKGROUND Hypoglycemia in preschool children limits the effectiveness of insulin therapy. Continuous subcutaneous insulin infusion (CSII) is not widely used in this group. OBJECTIVES This study was designed (1) to test the hypothesis that compared with twice-daily insulin injection, CSII decreases the SD of the mean daily blood glucose (BG) and improves glycemic control and (2) to evaluate the effect of CSII on parental anxiety using the Parental Stress Index (PSI) scale. METHODS Ten subjects <6 years of age and receiving insulin injections were recruited. Each underwent two 72-h CGMS (Medtronic Minimed, Northridge, CA) monitoring periods and then was started on CSII and re-monitored 3 and 6 months later. We assessed the effects of CSII on the mean BG and SD of BG values, A1c, PSI scores, and number, distribution, and duration of hypoglycemic episodes. RESULTS Pooled pre- and post-CSII data were compared. There was a 22% decrease in the BG variability (mean +/- SD 93 +/- 19 mg/dL vs. 72 +/- 5 mg/dL; P = 0.02) and a 13% decrease in A1c (8.6 +/- 0.8% vs. 7.5 +/- 0.7%; P = 0.01). There was a decrease in the 24-h median number and duration of hypoglycemic episodes [1.16 vs. 0 episodes/24 h (P = 0.01) and 1.19 vs. 0.05 h/24 h (P = 0.01), respectively], as well as the median number and duration of nighttime episodes [0.83 vs. 0 episode/night (P = 0.008) and 0.98 vs. 0 h/night (P = 0.008), respectively]. We found no statistically significant change in the PSI score. CONCLUSIONS CSII in preschool children is feasible and safe. Pump therapy reduced the glycemic excursions and decreased hypoglycemia duration and frequency.

Abstract
OBJECTIVE To determine using the MiniMed continuous glucose monitoring system (CGMS) 1) whether twice-daily insulin injection therapy achieves adequate control in preschool children with type 1 diabetes and 2) whether the CGMS is more informative than self-monitoring of blood glucose (SMBG) regarding glucose control and well tolerated by preschool children and their families. RESEARCH DESIGN AND METHODS Ten children <6 years of age with type 1 diabetes were monitored twice using the CGMS. The distribution of glucose values was analyzed, particularly the frequency, duration, and distribution of hypoglycemia. We analyzed the accuracy of the CGMS in detecting hypoglycemia as well as the clinical relevance of the difference between CGMS and SMBG values. RESULTS Although hypoglycemia was more frequent during the night (0.8 nighttime episodes . subject(-1) . 24 h(-1) vs. 0.3 daytime episodes . subject(-1) . 24 h(-1)), the difference did not reach statistical significance (P=0.07). However, nighttime episodes lasted longer than daytime episodes (1.2 vs. 0.2 h . subject(-1) . 24 h(-1), P=0.006). Hypoglycemia accounted for 7% and normoglycemia for 24%, while hyperglycemia occurred 64% of the time, with postprandial hyperglycemia being an almost universal feature (94 +/- 7% of all postmeal values). The CGMS correlated well with SMBG without significant clinical discrepancy. The CGMS sensitivity to detect hypoglycemia was 70% with a specificity of 99%; however, the CGMS detected twice as many total episodes as SMBG (82 vs. 40). CONCLUSIONS Twice-daily insulin injection rarely achieves control in preschool children with type 1 diabetes. The CGMS is well tolerated by patients and has the advantage of revealing daily glucose trends missed by SMBG.

Abstract
A 14-year-old female presented to the Pediatric Endocrine Clinic, Universidade Federal o Parana Curitiba, Brazil, for obesity. A few years later, despite normal breast development, the patient had failed to menstruate and lacked pubic and axillary hair. Laboratory analyses revealed high levels of testosterone. Karyotype analysis was XY. Direct sequencing of her genomic DNA showed a G to T transition at nucleotide 2089 at exon 2 in the androgen receptor gene, resulting in a substitution of Phe for Cys at position 576. This mutation disrupts the first Zn finger critical to DNA binding and transcriptional activity and results in complete androgen-insensitivity syndrome (CAIS). This individual was part of 700-member multigenerational kindred of German origin living in small villages in Southern Brazil. Family members who gave informed consent were screened using a polymerase chain reaction-based method. Nineteen CAIS-affected individuals and carriers were identified. All presented with infertility and lack of or sparse pubic hair. The prevalence of common AIS within the kindred greatly exceeds that of the general population and is due in part to their isolated familial and community structures. All individuals are genuinely feminine in their appearance, sex behavior, gender identity, and integration within their communities. We conclude that CAIS leads to complete feminization of XY individuals and results in individuals who are psychologically and socially established and integrated as women within the familial and cultural contexts of their communities.

Abstract
The combination of neurodevelopmental regression and adrenal insufficiency should alert practitioners or emergency room physicians about ALD. Although still unproven, early medical intervention with either gene therapy or bone marrow transplantation may offer more promise to these patients.

Abstract
The most common enzymatic defect of steroid synthesis is adrenal steroid 21-hydroxylase deficiency. Inhibited formation of cortisol causes increased pituitary release of ACTH, driving the adrenal cortex to overproduce androgens, whose synthesis does not involve the 21-hydroxylase enzyme. This hormonal setting is established in the embryonic period and affects development of genetic females, misdirecting differentiation of the external genitalia toward male type. At birth, the genitalia are visibly ambiguous (enlarged clitoris, fused labia) or in some cases even male in appearance (phallus with urethral opening, rugated scrotal sac), leading to wrong sex assignment. Adrenal steroid 21-hydroxylase deficiency is the most common basis of female pseudohermaphroditism. These females, however, have normal fertility and potential for gestation (gonads are functional and the internal duct-derived structures are well-formed), thus the sex of rearing should always be female. Management is by life-long hormonal (glucocorticoid) replacement, with surgical correction of the genital ambiguity. Prenatal diagnosis of 21-hydroxylase deficiency, first possible by steroid assay of the amniotic fluid, has utilized HLA typing for identification of loci (antigens B and DR) in close linkage with the 21-hydroxylase gene, and now increasingly relies on DNA analysis for linked HLA or C4 genes or for mutant 21-hydroxylase alleles directly by molecular genetic techniques. The most recent clinical advance is a program of combined prenatal diagnosis with karyotyping and suppression of fetal androgen production in genetic females by steroid administration to the mother. This is the first instance of an inborn metabolic error to be prenatally treated. A series of 85 managed pregnancies is reported on, including accuracy of diagnosis, response of the mother to steroid treatment, and outcome for treated and untreated male and female fetuses (of 77 born by 6/91). Prenatal diagnosis by current techniques is accurate. Normal growth and development patterns postnatally suggest that dexamethasone treatment is safe.
