Transient multiple pituitary hormone deficiency in critically ill pediatric patients

Dror Nitzan , Adam Dganit , Perl Liat , Eliakim Alon

Objective: Hospitalization in pediatric intensive care unit due to critical illness may be life threatening condition associated with severe acute physical stress and concomitant hormonal changes. Whether these changes represent an adaptive response or need to be treated is still not known.Methods: Pituitary hormones evaluation in four patients who were hospitalized in pediatric intensive care unit due to different sever...

Spatial navigation and memory in transgender male adolescents treated with gender affirming hormones

Perl Liat , Oren Asaf , C. Mueller Sven , Raphael Ido , Borger Ophir , Sheppes Tamar , Shechner Tomer

Background: Spatial navigation is an essential human skill that helps individuals track their changes in position and orientation by integrating self-motion cues. Meta-analyses indicate that males, on average, perform better than females on a number of spatial tasks. Sex steroids, mainly androgens, modulate the remodeling of synapses in the prefrontal cortex and hippocampus, a limbic brain area with critical influence on spatial and contextual memory. Androgen...

Dynamics in Blood Pressure After Pubertal Suppression with GnRH Analogs Followed by Testosterone Treatment in Male Adolescents

Perl Liat , Segev-Becker Anat , Israeli Galit , Elkon-Tamir Erella , Weintrob Naomi , Oren Asaf

Background: In 2017, the Endocrine Society published guidelines for the endocrine treatment of gender dysphoria/ gender incongruence. Adolescents who meet diagnostic criteria for gender dysphoria undergo pubertal suppression using gonadotropin-releasing hormone analogs (GnRHa) and induction of puberty with gender-affirming hormonal therapy. Blood pressure (BP) monitoring prior to and during treatment with GnRHa in transgender adolescents is recommended. This r...

Gender dimorphism in transgender youth – hormonal therapy and the balance between muscle, adipose tissue and cardiometabolic alterations

Borger Ophir , Oren Asaf , Perl Liat , Yackobovitch-Gavan Michal , Sheppes Tamar , Brener Avivit , Elkon-Tamir Erella , Israeli Galit , Segev-Becker Anat , Lebenthal Ophir Yael

Context: Given the importance of sex hormones in metabolic regulation, dynamics in body composition and cardiometabolic alterations may occur in transgender persons receiving gender-affirming hormone (GAH) therapy.Objectives: Our aim was to explore the association between muscle-to-fat ratio (MFR) and the risk for metabolic syndrome components in transgender youth.Methods: In 71 tr...

Endocrine-Metabolic Outcome of Women with a History of Sexual Precocity

de Vries Liat

Central precocious puberty (CPP) may have endocrine and metabolic implications in adulthood. Long-term effects may be associated with the underlying neuroendocrine dysfunction leading to CPP, the GnRH analogue (GnRHa) therapy, or both. Data are conflicting on the long-term risk of polycystic ovarian syndrome in both treated and untreated women. Clinical hyperandrogenism has been more frequently reported in CPP women than in controls, with no significant difference between GnRH...

Early Implementation of Insulin Pump Therapy after Diabetes Onset: is There Added Benefit?

de Vries Liat

Patients with type 1 diabetes (T1D) and their caregivers continue to face the challenge of maintaining blood glucose levels in the near-normal range, preventing sustained hyperglycemia associated with long-term microvascular and macrovascular complications, and avoiding recurrent episodes of hypoglycemia, especially at young ages when they can adversely affect cognitive function. In a follow-up to the Diabetes Control and Complications Trial, the Epidemiology of Diabetes Inter...

Clinical Criteria Remain Paramount for the Diagnosis of Polycystic Ovary Syndrome in the Adolescent Age Group

de Vries Liat , Weinberg Adi , Phillip Moshe

Background: Adolescent polycystic ovary syndrome (PCOS) may be difficult to distinguish from pubertal changes and diagnosis remains a challenge.Objective and hypotheses: To investigate the value of different biochemical parameters for the diagnosis of PCOS and also to assess the prevalence of non-classical congenital adrenal hyperplasia (NCCAH) among adolescent girls referred for clinical symptoms suggesting PCOS.Method: Retrospect...

Hypoglycemia in children: Clinical experience of a tertiary care center

Gil Margolis Merav , Lilos Pearl , Phillip Moshe , de Vries Liat

Introduction: Hypoglycemia is a significant cause of morbidity in children, yet is challenging to diagnose and treat due to its heterogeneity.Aim: To describe the diagnoses and clinical characteristics of children with hypoglycemia referred to a tertiary pediatric center.Methods: This retrospective study included 155 children (86 males, aged 0-18 years) diagnosed with hypoglycemia ...

Is Basal 17-Hydroxyprogesterone a Sensitive Marker for Diagnosis of Non-Classical Congenital Adrenal Hyperplasia?

Bello Rachel , Lebenthal Yael , Phillip Moshe , de Vries Liat

Background: A basal 17-hydroxyprogesterone (17-OHP) plasma level of 6.0 nmol/l was suggested as a threshold for the diagnosis of non-classical congenital adrenal hyperplasia (NCCAH), particularly in children presenting with precocious pubarche (PP).Objective: The present study aimed to determine if this threshold could lead to underdiagnosis of NCCAH.Method: In a retrospective study the cohort of pediatric patients (n=145,...
