The DHX37 gene has been identified to cause 46, XY disorders of sex development (DSD), yet there are no reports in China. Here, we report a Chinese pediatric case of 46, XY DSD identified by Whole-exome sequencing which carried a heterozygous missense mutation c.2020 C > T (P.R674 W) in DHX37 gene (NM _ 032656) inherited from the mother. Gonadal pathology showed that the left gonad was structured with a vas deferens and epididymal duct, and the right gonad had vas deferens,...

Background and Aims: A pre-clinical stage of type 1 diabetes (T1D) often precedes by many years the overt clinical symptoms. Diagnosis during this period is often difficult and is based on the presence of specific islet autoantibodies in the subject's blood. First-degree relatives of patients with T1D were tested using the 3 Screen ICA TM ELISA (RSR Ltd) for combined testing for autoantibodies to GAD65 (glutamic acid decarboxylase, 65kDa isoform), ZnT8 (z...

Background: Vitamin D deficiency may be associated with increased risk of metabolic syndrome.Objective and hypotheses: We aimed to assess the relation between 25-hydroxyvitamin D (25(OH) D) with the different metabolic syndrome components in overweight and obese subjects.Method: Ninety eight subjects (≥85th percentile for age and sex) recruited from the Diabetes, Endocrine & Metabolic Paediatrics Unit (DEMPU), Cairo Unive...

Background: Primordial dwarfism (PD) is a phenotype characterized by profound growth retardation and microcephaly that is prenatal in onset. Recently mutations in genes involved in ciliogenesis have been described in patients with primordial dwarfism phenotype. In 2012 mutations in rotatin (RTTN), a protein involved in cilia structure and function, have been described in in individuals with bilateral diffuse polymicrogyria, but not growth failure.Case pr...

Background: The aim of this study was to analyze the impact of the COVID-19 pandemic lockdown on behaviors and subsequent changes in BMI in children from southern Poland.Methods: The study included 206 participants (104 females and 102 males) with a complete analysis of 177 (96 females and 81 males) with a mean age of 12.8 ± 2.6 years admitted to three pediatric endocrinology clinics (Rzeszów, Kraków, and ...

Cancer treatment may result in development of long-term endocrine complications, including growth hormone (GH) deficiency.1 Although extensive and careful monitoring has been carried out to establish the safety profile of GH therapy,2 a relative scarcity of data means that questions persist around its use in survivors of childhood cancer. The effects of GH on growth and metabolism mean that there is a particular interest in whether GH therapy increases th...

Background: Foramen magnum stenosis (FMS) is a life-threatening complication in children with achondroplasia (ACH) which may require cervicomedullary decompression (CMD). There is no evidence if FMS and CMD affects growth in children with ACH.Aim: To evaluate the impact of FSM and CMD surgery on anthropometric measurements in children with ACH.Methods: Sixty-five patients with ACH ...

Background: Congenital hypothyroidism (CH) is a common and preventable cause of mental retardation in children, and is detected using dried blood spots in many neonatal screening programs. Upon suspicion of CH, plasma free thyroxine (FT4) and thyroid stimulating hormone (TSH) concentrations are measured. CH can be of thyroidal or central origin (CH-T and CH-C, respectively). While CH-T diagnosis is based on an elevated plasma TSH in combination with a low FT4,...

Parental imprinting is an epigenetic process leading to monoallelic expression of certain genes depending on their parental origin. Imprinting disorders are a set of rare diseases that mainly affect growth and metabolism from birth to adulthood. These disorders are mainly due to methylation defects in imprinting control region that drive the abnormal expression of imprinted genes. Moreover, patients with imprinting disorders may present overlapping clinical features that can b...

Background: Thymus transplantation is undertaken for conditions associated with severe immunodeficiency. These comprise a number of genetic and syndromic associations including 22q deletion syndrome, CHARGE association, diabetic embryopathy, and other rarer conditions. Autoimmune thyroid dysfunctions (Hashimoto's thyroiditis and Graves' Disease) are described in the literature as the most common autoimmune disease after thymic transplant.<p class="...
