Abstract
Objective Recent reports have indicated the role of the prokineticin receptor 2 gene (PROKR2) in the etiology of pituitary hormone deficiencies, suggesting a potential role for the PROK2 pathway in pituitary development, in addition to its role in gonadotropin releasing hormone-expressing neuron development. Here, we present the clinical and molecular findings of four patients with PROKR2 mutations. Methods Next-generation targeted sequencing was used to screen 25 genes in 59 unrelated patients with multiple pituitary hormone deficiency (MPHD), isolated growth hormone (GH) deficiency, or idiopathic short stature. Results Two different, very rare PROKR2 missense alterations classified as pathogenic (NM_144773.4:c.518T>G; NP_658986.1:p. (Leu173Arg)) and likely pathogenic (NM_144773.4:c.254G>A; NP_658986.1:p.(Arg85His)) were identified in four patients in heterozygous form. Patient 1 and Patient 2 presented with short stature and were diagnosed as GH deficiency. Patient 3 and Patient 4 presented with central hypothyroidism and cryptorchidism and were diagnosed as MPHD. No other pathogenic alterations were detected in the remaining 24 genes related to short stature, MPHD, and hypogonadotropic hypogonadism. Segregation analysis revealed asymptomatic or mildly affected carriers in the families. Conclusion PROKR2 dominance should be kept in mind as a very rare cause of GH deficiency and MPHD. Expressional variation or lack of penetrance may imply oligogenic inheritance or other environmental modifiers in individuals who are heterozygous carriers.

Abstract
IGSF1 deficiency is a rare X-linked condition characterized by central hypothyroidism and a wide variety of other clinical features with variable prevalence, including a delayed pubertal testosterone rise and growth spurt in the context of normal or accelerated testicular growth, and adult macroorchidism with relatively low serum testosterone concentrations. Other features include increased waist circumference, attention deficit, prolactin deficiency and transient partial growth hormone (GH) deficiency in childhood, contrasting with an increased GH secretion in adulthood. Patients with this disorder are not detected shortly after birth if neonatal screening programs are based on thyroid-stimulating hormone (TSH) concentrations. A 13.2-year-old male patient was referred to pediatric endocrinology for evaluation of short stature. He was born large for gestational age into a nonconsanguineous family. During work-up for short stature, deficiencies of TSH, prolactin and GH were detected, leading to treatment with levothyroxine and GH. At 16.9 years, GH treatment was stopped and during transition to adult care, his insulin-like growth factor 1 level was above the normal range. This prompted an analysis of IGSF1, in which a novel hemizygous variant causing a stop codon at c.3559C>T (p.Q1187*) was found, confirming the diagnosis of IGSF1 deficiency syndrome. In this report, we describe his clinical and hormonal characteristics at presentation and during long-term follow-up.

Abstract
Objective A significant rise in the number of trans adolescents seeking medical interventions has been reported in recent years. The aim of this study was to report the clinical features, treatment, and follow-up of adolescents with gender dysphoria (GD) with our increased experience. Methods Twenty-six male-to-female (MTF) and twenty-seven female-to-male (FTM) adolescents who were referred to the GD-outpatient clinic between 2016 and 2022 were reviewed. The clinical and laboratory findings of thirty transgender adolescents (15 FTM /15 MTF) who received medical intervention were evaluated retrospectively. Results Most individuals (60.4%) were admitted between 2020 and 2022, and the remaining (39.6%) were admitted between 2016 and 2019. At the time of referral, median age was 16.3 years [interquartile range (IQR) 1.53; range 13.2-19.4] in 26 MTF, and 16.4 years (IQR 1.74; range 11.7-21.6) in 27 FTM adolescents. The median age at pubertal blockage with gonadotropin-releasing hormone analog and androgen receptor blocker was 16.4 years (IQR 1.4; range 11.7-17.8) in 22 adolescents (9 MTF, 13 FTM), and 17.4 years (IQR 1.4; range 15.5-19.4) in 6 MTF individuals, respectively. Cross-sex hormone therapy was commenced in 21 adolescents (12 MTF, 9 FTM) at the median age of 17.7 years (IQR 0.61; range 16-19.5). Fifteen individuals (8 MTF, 7 FTM) have been transferred to the adult endocrinology department in transition clinics. Conclusion All treatments were generally well tolerated and effective, including bicalutamide, and no significant side effects were observed. Transition clinics played an important role in the better management of gender reassignment processes.

Abstract
BACKGROUND : In this cross-sectional study, we aimed to evaluate auxological measurements and detailed body proportions of recombinant human growth hormone (GH)-treated patients with Turner syndrome (TS) and compare them with a group of healthy females. METHODS We evaluated 42 patients with TS who received GH treatment and 20 healthy controls. Anthropometric measurements were taken and target height, body mass index (BMI), arm span-height difference, extremity-to-trunk ratio, and Manouvrier's skelic index were calculated. RESULTS : The median (min-max) age of the patients at the time of evaluation was 13.6 (4.3-20.7) years, and the control group was 12.9 (3.8-23.7) years. Height, sitting height, and arm span of TS patients were significantly lower than those of the control group. Sitting height/height ratio (SHR) was in normal ranges in both groups and BMI was significantly higher in TS patients when compared to the control group. According to Manouvrier's skelic index, TS patients had shorter legs than the control group (p = 0.001). The extremity-trunk ratio was significantly decreased in TS patients compared to healthy controls (p < 0.001). There was no significant difference between the karyotype groups in terms of these indexes. DISCUSSION TS patients had short stature, increased BMI and waist circumference, normal head circumference, and decreased extremity-trunk ratio. Sitting height and leg length were short; however, the SHR standard deviation score (SDS) was in the normal range. Despite being treated with GH, TS patients had disproportionate short stature. The disproportion in TS patients was similar to short-stature homeobox-containing gene (SHOX) deficiency, which is considered to be SHOX haploinsufficiency in the etiopathogenesis of short stature.

Abstract
Papillary thyroid cancer (PTC) is extremely rare in children. Herein, we present a case diagnosed with PTC at 15 months of age. We conducted a literature review of the published cases with PTC under five years of age. A 1.25-year-old male patient had initially presented with a complaint of progressively enlarging cervical mass that appeared four months earlier. On physical examination, a mass located in the anterior cervical region with the largest measurements of around 3x3 cm was detected. Cervical and thyroid ultrasonography showed a 50x27 mm solid mass in the right lateral neck. Excisional biopsy revealed a follicular variant of PTC with capsular invasion. Subsequently, he underwent a complementary total thyroidectomy. He was diagnosed with intermediate-risk (T3N0M0) PTC. He developed permanent hypoparathyroidism. In the first year of the operation, he was treated with radioiodine ablation (RAI) since basal and stimulated thyroglobulin (Tg) levels tended to increase. Whole-body scintigraphy was normal in the first year of RAI ablation. On levothyroxine sodium (LT4) treatment, levels of thyroid stimulating hormone (TSH) and Tg were adequately suppressed. He is now 8.5-years-old and disease-free on LT4 replacement therapy for seven years and three months. Pediatric PTC has different biological behavior and an excellent prognosis compared to adults. The optimal treatment strategy for pediatric TC is total thyroidectomy, followed by RAI ablation. Post-operative management should include regular follow-up, TSH suppression by adequate LT4 therapy, serial Tg evaluation, and radioiodine scanning when indicated.

Abstract
BACKGROUND Osteogenesis imperfecta (OI) is a genetic disease characterized by fragile bones and variable short stature. METHOD We performed a retrospective cohort study to evaluate demographic data, clinical findings, growth and pubertal characteristics, and medical treatment of 83 OI patients. RESULTS 83 (31 female/52 male) patients were enrolled in the study. The median follow-up duration was 4.7 (0.6-17.7) years. 51 out of 83 patients (61.4%) received bisphosphonate therapy. The median Z-score of the bone mineral density improved in patients with OI-I and OI-III with the treatment. During follow-up, height-SDS significantly increased in both OI-I and OI-III on treatment; however, final adult height SDS of patients did not improve. The frequency of overweight and obesity was found to be increased at the last evaluation compared to the admission. The rate of precocious puberty (PP) and early puberty (EP) were 20 and 10% in girls, and they were 15.7 and 47.3% in boys, respectively. CONCLUSION Reduced growth, significant weight gain over time due to impaired mobility, and high frequency of PP/EP require effective interventions to improve mobility and functional parameters as early as possible in children with OI.

Abstract
CONTEXT Central precocious puberty (CPP) may arise from central nervous system (CNS) lesions in a few affected girls. Recently, the incidence of girls with CPP has increased mostly in 6-8 year olds, in whom the necessity of magnetic resonance imaging (MRI) is debated. OBJECTIVE To investigate the frequency, long-term outcome and potential predictors of CNS lesions in a large cohort of girls with CPP. METHODS A multicenter cohort of 770 Turkish girls with CPP who had systematic cranial MRI between 2005 and 2017. Age at puberty onset was <6 years in 116 and 6-8 years in 654. CNS lesions were followed until final decision(6.2 ± 3.1 years). Potential predictors of CNS lesions were evaluated by univariate analyses. RESULTS A total of 104/770 (13.5%) girls had abnormal brain MRI. Of these, 2.8% were previously known CNS lesions, 3.8% had newly detected and causally related CNS lesions, 3.1 % were possibly, related and 3.8% were incidental. Only 2 (0.25%) neoplastic lesions (1 low grade glioma and 1 meningioma) were identified; neither required intervention over follow-up of 6 and 3.5 years respectively. Age at breast development <6 years (odds ratio [OR] 2.38; 95% CI 1.08-5.21) and the peak luteinizing hormone/follicle-stimulating hormone (LH/FSH) ratio >0.6 (OR 3.13; 95% CI 1.02-9.68) were significantly associated with CNS lesions. However, both patients with neoplastic lesions were >6 years old. CONCLUSION Although age and LH/FSH ratio are significant predictors of CNS lesions, their predictive power is weak. Thus, systematic MRI seems to be the most efficient current approach to avoid missing an occult CNS lesion in girls with CPP, despite the low likelihood of finding a lesion requiring intervention.
