#1
Amir Weintraub, Talia Eldar-Geva
Anti-Mullerian hormone (AMH), secreted by immature testicular Sertoli-cells, triggers the regression of male fetal Mullerian ducts. During puberty, AMH is downregulated by intratesticular testosterone. In females, AMH is secreted from granulosa cells of immature ovarian follicles from late prenatal life until menopause; serum concentration is 5-20 times lower in females than in males through lifetime. In boys, AMH determination is useful in the clinical setting as a marker of Sertoli cell function. Serum AMH is low in infants with hypogonadotrophic hypogonadism (and increases with FSH treatment), in patients with primary hypogonadism from early postnatal life and in Klinefelter syndrome from midpuberty...

BACKGROUND: Well-differentiated thyroid cancer is the most common endocrine malignancy in children. Adult literature has demonstrated socioeconomic disparities in patients undergoing thyroidectomy, but the effects of socioeconomic status on the management of pediatric well-differentiated thyroid cancer remains poorly understood. METHODS: Patients ≤21 years of age with well-differentiated thyroid cancer remains were reviewed from the National Cancer Data Base...

We analyzed the relation of pretreatment anthropometric measures and serum thyrotropin (TSH) with the levothyroxine requirement. Children (3-18 years) brought to endocrine clinic with newly diagnosed acquired primary hypothyroidism were enrolled consecutively and prospectively with follow-up (July 2014 to April 2016). Children were started on levothyroxine, and dose was adjusted at regular intervals until achieved euthyroidism (serum TSH 0.4 to 4.5 mIU/L). The relationship of age, gender, height, weight, and serum TSH with levothyroxine dose was analyzed by univariate and multivariate regression analysis...

The endocrine system is crucial for maintaining whole-body homeostasis. Little is known regarding endocrine hormones secreted by the heart other than atrial/brain natriuretic peptides discovered over 30 years ago. Here, we identify growth differentiation factor 15 (GDF15) as a heart-derived hormone that regulates body growth. We show that pediatric heart disease induces GDF15 synthesis and secretion by cardiomyocytes. Circulating GDF15 in turn acts on the liver to inhibit growth hormone (GH) signaling and body growth...

PURPOSE: Insulin resistance (IR) has an important role in the development of non-alcoholic steatohepatitis (NASH). We aimed to analyze the association between liver histopathology and IR in pediatric patients with NASH. MATERIALS AND METHODS: In 24 children with non-alcoholic fatty liver disease (NAFLD), we investigated whether the hepatic pathologic characteristics have relations with following three biochemical indices; IR index including homeostasis model assessment of IR (HOMA-IR), quantitative insulin sensitivity check index (QUICKI), and insulin sensitivity indices-free fatty acid (ISI-FFA)...

Multimodal treatment in high-risk neuroblastoma has modestly improved survival; limited data exist on the late effects from these regimens. We report the sequelae of treatment incorporating 3 consecutive cycles of high-dose therapy and autologous stem cell transplants (ASCTs) without the use of total body irradiation (TBI). We reviewed the medical records of 61 patients treated on or following the Chicago Pilot 2 protocol between 1991 and 2008. Of the 25 patients who are alive (41%), 19 had near complete data to report...

The evaluation and management of a newborn with ambiguous genitalia must be undertaken as quickly as possible and with great sensitivity for the child's family. Where possible, a comprehensive team approach with a pediatric urologist, endocrinologist, geneticist, neonatologist, and child psychiatrist/psychologist should work closely with the family to establish the diagnosis and determine gender. Although the preferred gender assignment is not always clear, a thorough examination of endocrine function, karyotype, and potential for fertility should guide the determination...

PURPOSE OF REVIEW: The Pediatric Endocrine Society recently published new guidelines for the use of human growth hormone (hGH) and human insulin-like growth factor-I (hIGF-I) treatment for growth hormone deficiency, idiopathic short stature, and primary IGF-I deficiency in children and adolescents. This review places the new guidelines in historical contexts of the life cycle of hGH and the evolution of US health care, and highlights their future implications. RECENT FINDINGS: The new hGH guidelines, the first to be created by the Grading of Recommendations Assessment, Development and Evaluation approach, are more conservative than their predecessors...

OBJECTIVES: Congenital hypothyroidism (CH) is most frequently encountered in newborns as an endocrine disorder characterized by thyroid hormone deficiency, and is one of the most common reasons for preventable mental retardation. This prospective study was designed to detect the pediatric occurrences of CH followed as euthyroid, with no anomalies detected via US on the gray scale, in comparison with a pediatric group with normal levels. METHODS: A total of 42 apparently healthy children with no thyroid disorder (Group 1) and 54 euthyroid CH (Group 2) using thyroid hormone were included in this study...

BACKGROUND: Ovarian tumors, although uncommon in children, can retain endocrine function that disrupts normal feedback mechanisms leading to amenorrhea. Inheritance of germline DICER1 mutations can lead to increased risk for development of ovarian Sertoli-Leydig cell tumors (SLCT). CASE: We report the first case of secondary amenorrhea due to elevated inhibin B levels in an adolescent female with an ovarian SLCT. SUMMARY AND CONCLUSIONS: Ovarian tumors should be included in the differential diagnosis for pediatric patients presenting with menstrual irregularities...

BACKGROUND: The adverse effects of irradiation on endocrine function among patients with pediatric brain tumor are well documented. Intensive induction chemotherapy followed by marrow-ablative chemotherapy with autologous hematopoietic cell rescue (AuHCR) without central nervous system (CNS) irradiation has demonstrated efficacy in a proportion of very young children with some malignant CNS tumors. This study assessed the long-term endocrine function of young children following chemotherapy-only treatment regimens...

REVIEW
Jens F Rehfeld
Cholecystokinin (CCK) was discovered in 1928 in jejunal extracts as a gallbladder contraction factor. It was later shown to be member of a peptide family, which are all ligands for the CCK1 and CCK2 receptors. CCK peptides are known to be synthetized in small intestinal endocrine I-cells and cerebral neurons. But in addition, CCK is expressed in several endocrine glands (pituitary cells, thyroid C-cells, pancreatic islets, the adrenals, and the testes); in peripheral nerves; in cortical and medullary kidney cells; in cardial myocytes; and in cells of the immune system...

OBJECTIVE: To study the contribution of hormonal cytology in contemporary disturbances of fertility. DESIGN: Over a 10-year period (2006-2015), 6,688 vaginal fornix cytologies of 2,350 patients were investigated. For a more detailed analysis, a 3-year period from 2013 to 2015 was chosen. Four hundred and fifty-two patients were investigated, many of them several times and for a period longer than the 3 years analyzed. RESULTS: The main disorders examined and treated via a gentle hormonal medication support and life style corrections by a pediatric gynecologist were: pubertas praecox - thelarche praecox and early menarche; dysfunctional juvenile metrorrhagia; central and peripheral endocrine disorders; eating disorders - anorexia mentalis and bulimia; obesity; excessive sport activities; autoimmune disorders, and others...
