OBJECTIVES: Adiponectin/leptin ratio (ALR) is a promising novel marker of cardio-metabolic risk in patients with metabolic syndrome. Our aim was to study the association of adiponectin-leptin ratio with markers of obesity and adiposity and also to assess its usefulness as a marker of increased cardiometabolic risk (CMR) in Indian children and youth with type 1 diabetes mellitus.

We also attempted to determine the cut-off level of the fluorometric method used for screening biotinidase deficiency by the Ministry of Health. METHODS: A total of 700 subjects who were referred to the Pediatric Metabolism Outpatient Clinic with a preliminary diagnosis of biotinidase deficiency through the national newborn metabolic screening program were retrospectively evaluated...

BACKGROUND: The COVID-19 pandemic had profound effect on physical and mental health. Stress was due physical inactivity, increased screen time, social isolation, fear of illness/death, as well as relative lack of resources including healthy food and finances. These stressors may be associated with an increase in idiopathic central precocious puberty (ICPP). OBJECTIVES: To assess the incidence of ICPP in females during the COVID-19 pandemic and compare biochemical and radiological parameters of females diagnosed in the previous two years, looking at associations among BMI, screen time, isolation, and stress in relation to the development of early puberty...

OBJECTIVES: In this study, we examined executive function (EF) abilities, behavioral and emotional (BE) issues, and overall quality of life (QoL) of adolescents with obesity and compared them with a control group and also aimed to investigate whether the presence of insulin resistance (IR) is associated with these problems. METHODS: This cross-sectional study included a sample of 50 adolescents aged 11-18 years with obesity and age- and gender-matched 50 normal weight adolescents who had attended and were treated at the pediatric outpatient clinic...

OBJECTIVES: Activating variants of the ABCC8 gene cause neonatal diabetes or maturity-onset diabetes of the young (MODY). We report three cases of MODY type 12 caused by variants in the ABCC8 encoding sulphonylurea receptor 1, and the experience of switching from insulin therapy to sulphonylurea therapy. CASE PRESENTATIONS: We describe a 12.5-year-old girl with permanent neonatal diabetes mellitus, and two diabetes mellitus cases with variants in the ABCC8 gene...

OBJECTIVES: Polycystic ovary syndrome (PCOS) increases non-alcoholic fatty liver disease (NAFLD) risk and severity in adults, but data in adolescents with diverse backgrounds are limited. We evaluated NAFLD prevalence and characterized NAFLD risk factors in overweight/obese adolescents by PCOS status. METHODS: Retrospective study of overweight (n=52)/obese (n=271) female adolescents (12-18 years old), evaluated clinically 2012-2020, was conducted comparing PCOS patients to age-matched non-PCOS controls...

OBJECTIVES: This report presents a case of acute onset of chorea, concurrent Graves' disease, and acute rheumatic fever in an 8-year-old female patient. CASE PRESENTATION: The child had intermittent involuntary movement of all extremities and both eyes for 4 days, with a previous history of increased appetite, weight lost, and heat intolerance over a period of two months. Physical examination revealed fever, tachycardia, exophthalmos, eyelid retraction, as well as diffused thyroid enlargement...

OBJECTIVES: Congenital Glycosylation Disorders (CDG) are a large group of inherited metabolic diseases with multi-organ involvement. Herein, we aimed to expand the clinical characteristics of patients with CDG based on our experience with diagnoses and follow-up of CDG patients from different subtypes. METHODS: The clinical and laboratory findings from the last 15 years were reviewed retrospectively in Ege University Child Metabolism and Nutrition Department. RESULTS: There were 8 (57...

OBJECTIVES: GM1-gangliosidosis is an autosomal recessive lysosomal storage disorder caused by beta-galactosidase deficiency encoded by GLB1. It is mainly characterized by progressive neurodegeneration due to accumulation of glycosphingolipids in central nervous system and classified into 3 forms according to the age of onset and severity of symptoms. CASE PRESENTATIONS: In this study, we described the demographic, clinical, molecular, biochemical characteristics of 4 patients from 3 unrelated families diagnosed with GM1-gangliosidosis...

OBJECTIVES: There have been recent advances assessing copeptin levels in adults with suspected disorders of vasopressin release. Very limited data exits on copeptin levels in children and infants, especially in a critically-ill hospitalized population where hyper- and hypo-natremia are very common. Our objective is to describe the institutional experience assessing copeptin levels in hospitalized infants and children with hyper- or hypo-natremia. METHODS: We performed a single-center retrospective case series of all infants, children, and adolescents who had an ultrasensitive plasma copeptin level obtained between 2019-2021...

OBJECTIVES: The Internet, an integral part of modern life, can lead to internet addiction, which negatively affects academic performance, family relationships, and emotional development. This study aimed to evaluate the Internet addiction scores (IAS) during COVID-19 in children with type 1 diabetes mellitus (T1DM) compared with healthy controls.

OBJECTIVES: Children 10-20 years old in the US are currently obese, showing suboptimal hydration as 60% fail to meet the US Dietary Reference Intakes for water. Studies have shown a significant inverse association between hydration status and body composition in children, although most failed to use the Dual-X-Ray Absorptiometry Scan (DEXA), the gold standard for body composition. Limited studies used an objective marker to measure hydration, such as urine specific gravity (USG) from a 24-h urine collection...
