Background: A broad spectrum of human diseases including abnormalities in steroidogenesis is caused by mutations in the NADPH P450 oxidoreductase (POR). POR transfers electrons from NADPH to several small molecules, non-P450 redox partners and all microsomal cytochrome P450 proteins. POR disruption affects all partners with disastrous consequences and POR knock-out mice are embryonically lethal. A number of POR mutations and polymorphisms have been characterized from patients ...

Background: In 1968 a cytogenetics laboratory was established at the University Hospital, Reykjavik and has since then served as the only chromosomal laboratory for all hospitals and physicians in Iceland. Our current aim was to study the physical features, congenital anomalies and various clinical outcomes in Icelandic females, diagnosed with Turner syndrome (TS) for the period of 1968–2012.Method: Data was obtained from hospital records, from all ...

The metabolism of several trace elements is altered in diabetes mellitus (DM). The present study investigates serum levels of lipid profile and lipid per-oxidation as well as levels of Mg, Cu, Ni, Co, Mn, Cr, Se, V and Zn, in 72 males with non-insulin-dependent DM (T2DM) and 21 non-diabetic healthy control subjects using inductively coupled plasma optical emission spectrometry (ICP-OES). The results showed highly significant increase in serum concentrations of LDL-C, TG and ch...

Background: Fatty liver disease in children and adolescents is the most common cause of chronic liver disease in many countries. Criteria for a diagnosis of pediatric metabolic associated fatty liver disease (MAFLD) are based on hepatic steatosis in ultrasound, blood biomarkers or liver biopsy in association with one of the three criteria: excess adiposity (overweight, obesity or abdominal obesity), prediabetes or type 2 diabetes, or evidence of metabolic dysr...

Introduction: Insulin (INS) gene is reported to be the most important gene involved in Type 1 Diabetes (T1D); its expression is inversely correlated with methylation at CpG sites. Hypermethylated primers are associated with decreased expression.Aim: The present study aims to investigate possible differences in DNA methylation pattern between T1D youngsters and healthy controls.Patients and Methods: Twenty T1D parti...

Puberty is a physical, hormonal and psychosocial transition from childhood to adolescence. Precocious puberty (PP) is the beginning of secondary sexual characteristics before eight years of age in girls. The most common type is known as “central precocious puberty (CPP)”. CPP occurs due to early activation of the hypothalamus-pituitary-gonad (HPG) axis. Although the real trigger for idiopathic CPP is unknown, it has been proposed that it may be caused by the interact...

The melanocortin-4 receptor (MC4R) pathway is critical for the regulation of hunger, energy balance, and weight regulation. Individuals who carry variants in MC4R pathway genes may present with early-onset severe obesity and hyperphagia. Historically, genetic testing in individuals with severe obesity has been limited. The Rare Obesity Advanced Diagnosis™ genetic testing program aims to enhance access to genetic testing for European individuals with suspected rare geneti...

Purpose: We aimed to determine the frequency and distribution of intracranial pathologies in patients over 8 years of age by evaluating MRI images of patients diagnosed with early puberty-rapidly progressive.Materials and Methods: The study comprised 118 female patients diagnosed with precocious puberty (PP) and rapidly progressive early puberty (RPEP). The onset of puberty in girls before the age of 8 years is defined a...

Background/Aims: Since the introduction of Assisted Reproduction Technologies (ART), including classic In Vitro Fertilization (IVF) and Intacytoplasmic Sperm Injection (ICSI), in clinical practice, several studies have addressed concerns regarding the long-term health of the offspring, revealing indications of an adverse cardiometabolic outcome. Proprotein convertase subtilisin/kexin type 9 (PCSK9) circulating level is significantly associated with an increased risk of cardiov...

Background: Using ultrasound to examine the glandular breast tissue is a promising method for staging pubertal breast development. However, breast ultrasound for this purpose has not been explored in a large sample of healthy girls in different developmental stages, and normative data have been unavailable.Objective: To present novel pubertal references for breast ultrasound stages, Tanner breast (B) and pubic hair (PH) ...
