Multiple Malformations Extending the Phenotypic Spectrum of Antley–Bixler Syndrome in a Patient with P450 Oxidoreductase Deficiency due to Two Novel Mutations of the POR Gene

Janchevska Aleksandra , Idkowiak Jan , Caredda Elisabeta , Hurst Jane , Dattani Mehul T , Arlt Wiebke , Spoudeas Helen A

Background: P450 oxidoreductase deficiency (PORD) is characterised by glucocorticoid and sex steroid deficiency and skeletal malformations, resembling Antley–Bixler syndrome (ABS, MIM 124015), a skeletal malformaton phenotype also present in patients with fibroblast growth factor receptor 2 mutations (FGFR2, MIM 176943). While genetic testing confirms both conditions, establishing the exact diagnosis on clinical grounds can be challenging.Objective ...

Neuroendocrine Consequences of Hypothalamic Hamartoma and their Imaging (MRI) and Surgery Correlates

Corredor Beatriz , Caredda Elisabetta , Ederies Ash , Tisdall Martin , Cross Helen , Spoudeas Helen A.

Background: Hypothalamic hamartomas(HH) are rare heterotopic congenital malformations causing central precocious puberty(CPP) and/or resistant epilepsy whose natural history is unknown.Aim: To describe clinical and imaging features, and the risk of developing endocrine deficits, particularly after surgery.Method: Retrospective case note and imaging review of all HH diagnosed by MRI between 30.08.1991 and 24.11.17, analysed by initi...

Endocrine Dysfunction in Hypothalamic Hamartoma Depends on Presentation (Endocrine or Epileptogenic), Radiological Characteristics and Surgery

Caredda Elisabetta , Wilkinson Robert , Ederies Ash , Improda Nicola , Varadkar Sophia , Cross Helen , Tisdall Martin , Spoudeas Helen A

Background: Hypothalamic hamartomas(HH)-rare heterotopic congenital malformations (incidence 1:200 000)-present with central precocious puberty (CPP) or gelastic seizures (GS) but their natural history and best treatment strategy are unknown. Given their proximity to the hypothalamus–pituitary axis, wider endocrine dysfunction may be expected.Objective and hypotheses: To describe clinical features and any evolving endocrinopathies in HH patients, by...

Vitamin B12 Levels in Children After Metformin Treatment

Yordanova Desislava , Todorova Zdravka , Dimitrova-Mladenova Mihaela , Stefanova Elisaveta

Background and Aims: Vitamin B12 is an essential micronutrient required for optimal hemopoetic, cardiovascular and neuro-cognitive functions. There are some literature data that Metformin induces vitamin B12 malabsorption, which may increase the risk of developing vitamin B12 deficiency and subsequently elevation of homocysteine levels. High concentrations of homocysteine has been associated with higher risk of coronary artery disease, arterial hypertension, h...

25-Hydroxyvitamin D Concentrations in Pubertal Children with Obesity

Yordanova Desislava , Stefanova Elisaveta , Kazakova Krasimira , Todorova Zdravka , Dimitrova Mihaela

Background: The prevalence of childhood obesity has been rapidly increasing worldwide and the last report of World Health Organisation define it as epidemic and one of the most serious global public health challenges for the 21st century. Obese children and adolescents are at an increased risk of developing various health problems including type 2 diabetes mellitus, hypertension, osteoarthritis, cardiovascular disease. Obesity is a risk factor for vitamin D deficiency. Vitamin...

Untreated Congenital Hyperplasia with Central Precocious Puberty

Dimitrova Mihaela , Stefanova Elisaveta , Kazakova Krasimira , Yordanova Desislava , Todorova Zdravka

Background: Congenital adrenal hyperplasia (CAH) may cause early maturation of hypothalamic–pituitary–gonadal axis when the initiation of corticosteroid treatment is late or/and there is poor compliance. The latter sometimes leads to a lack of treatment. In most cases, if the child survives, he or she develops central precocious puberty.Case report: We present a 12-year-old boy born of a normal pregnancy and delivery. In the first months of lif...

Genetically Proven APS Type 1 in Two Siblings

Yordanova Desislava , Stefanova Elisaveta , Kazakova Krasimira , Todorova Zdravka , Dimitrova Mihaela

Background: APS type 1 is characterized by an autosomal recessive inheritance. The clinical diagnosis is based on the presence of at least two of the three following diagnostic criteria: chronic mucocutaneous candidiasis, chronic hypoparathyroidism, and autoimmune adrenal insufficiency. Patients often develop other autoimmune diseases. APS type 1 is caused by mutations in the AIRE gene which encodes the AIRE protein. The protein probably acts as a transcription factor.<p c...

Intergenerational Programming of Metabolic Disease via the Paternal Lineage

Patti Mary Elisabeth

Background: Common metabolic diseases, including diabetes and obesity, are the result of interactions between genes and environment. It is well-recognized that the maternal intrauterine environment is an important modifier of this risk. Thus, fetuses carried by women who are obese, diabetic or suffer from suboptimal nutrition are at increased risk of insulin resistance, obesity, type 2 diabetes (T2D), and cardiovascular disease as adults. Emerging data indicate that paternal e...

Metabolic Profile of Neonates With Different Duration of Gestation and Different Size at Birth

Kocova Mirjana , Palcevska-Kocevska Snezana , Krstevska Marija , Sukarova-Angelovska Elena , Zisovska Elizabeta

Background: Controversial findings about the metabolic profile in newborns depending on the length of gestation and size at birth have been reported.Objective and hypotheses: Insulinemia, adiponectin, and leptin levels are different in children born prematurely and SGA neonates compared to term normal newborns.Method: 196 healthy newborns were studied at the age 3-4 days. Birth weight (BW), birth length (BL), BMI, ponderal index (P...

Skeletal Dysplasia with Short Stature and a Larsen-Like Phenotype due to a Homozygous Mutation in B3GAT3

Steichen-Gersdorf Elisabeth , Laccone Franco

Background: Proteoglycans are abundant and structurally complex bio macromolecules. They reside on the cell surface and are a major component of the extracellular matrix including bone. Defective formation of proteoglycans may case pleiotropic connective tissue syndromes including EDS-like and Larsen syndrome–like phenotypes.Objective and hypotheses: We report on a girl with disproportionate short stature and joint laxity with pes planus and radial ...
