New-onset diabetes in children during the COVID-19 Pandemic: an assessment of biomarkers and psychosocial risk factors at play in Mississippi.

Purpose: The coronavirus disease 2019 (COVID-19) pandemic has led to an association between COVID-19 and pediatric diabetes. Studies have indicated the increased likelihood of children with COVID-19 infection developing diabetes. Our objective was to assess not only the increase in pediatric diabetes at our hospital and identify possible risk factors, but also to correlate the psychosocial changes resulting from the pandemic with new-onset diabetes.

Textile dye removal in wastewater by peroxymonosulfate (PMS) activation on a zero-valent iron nanoparticle-modified ultrafiltration catalytic membrane (nZVI@PES).

The use of the nano zero-valent iron (nZVI) nanoparticle-based advanced oxidation systems in conjunction with an activator such as peroxymonosulfate (PMS) to generate hydroxyl and sulfate radicals for the degradation of organic pollutants has been extensively used in recent studies. In this study, a nZVI-modified polyethersulfone (PES) membrane (nZVI@PES) was produced successfully by attaching the nZVI catalytic nanoparticles on the surface of a commercial microporous polymeric membrane material using a simple and easy filter press coating method. The presence of nZVI nanoparticles on the nZVI@PES membrane was confirmed by XRD, SEM, and EDS analyses.

A novel homozygous nonsense NDNF variant in Kallmann syndrome.

Kallmann syndrome (KS) is a rare genetic disease characterized by pubertal failure and olfactory defects. Although many genes associated with KS have been reported, most are rare. Recently, heterozygous inactivating mutations in the neuron-derived neurotrophic factor gene (NDNF) were reported to cause KS.

Pathogenic Variants in ZSWIM7 Cause Primary Ovarian Insufficiency.

Context: Primary ovarian insufficiency (POI) is a genetically heterogeneous condition associated with infertility and an increased risk of comorbidities. An increased number of genes implicated in DNA damage response pathways has been associated with POI as well as predisposition to cancers.

Objective: We sought to identify and characterize patients affected by POI caused by pathogenic variants in genes involved in DNA damage response during meiosis.

DLG2 Mutations in the Etiology of Pubertal Delay and Idiopathic Hypogonadotropic Hypogonadism.

Introduction: Idiopathic hypogonadotropic hypogonadism (IHH) is caused by dysfunction of the hypothalamic-pituitary-gonadal axis. DLG2 was recently implicated as a gene associated with delayed puberty and which may also contribute to IHH. The confirmation of the candidate puberty genes in independent IHH cohorts has become crucial due to the lack of proper genotype-phenotype segregations in reported pedigrees.

Gender Identity and Assignment Recommendations in Disorders of Sex Development Patients: 20 Years’ Experience and Challenges.

Objective: Gender assignment in infants and children with disorders of sex development (DSD) is a stressful situation for both patient/families and medical professionals.

Results: The mean age of the 226 patients with DSD at the time of first admission were 3.

A Novel Frameshift Mutation in ESCO2 Gene in Roberts Syndrome.

Roberts syndrome is a very rare autosomal recessive inheritance pattern genetic disorder characterised by symmetric bilateral extremity deformities, midfacial defect, and severe intellectual deficit. These patients also grow slowly prenatal and postnatal. RBS is caused by mutation in the ESCO2 gene.

Impaired glucose tolerance in Fanconi-Bickel syndrome: Eight patients with two novel mutations.

Şeker-Yılmaz B, Kör D, Bulut FD, Yüksel B, Karabay-Bayazıt A, Topaloğlu AK, Ceylaner G, Önenli-Mungan N. Impaired glucose tolerance in Fanconi-Bickel syndrome: Eight patients with two novel mutations. Turk J Pediatr 2017; 59: 434-441.

Withdrawal syndrome and hypomagnesaemia and in a newborn exposed to valproic acid and carbamazepine during pregnancy.

The usage of drugs during pregnancy affect the fetus and the newborn. In this report, we present findings from a newborn baby, whose mother was epileptic, and was under the treatment of valproic acid and carbamazepine during pregnancy. We have found symptoms of withdrawal syndrome, hyponatremia and feeding problem, which was most probably related to exposure to the mentioned drugs.

Sertoli cell only syndrome with ambiguous genitalia.

The Sertoli cell only syndrome (SCOS) is a rare genetic disorder with a variable phenotype ranging from a severe ambiguous genitalia to a normal male phenotype with infertility. SCOS is diagnosed on testicular histopathology as germ cells are absent without histological impairment of Sertoli or Leydig cells. The SRY positive XX male syndrome is usually diagnosed in adulthood during infertility investigations.

Anthropometric findings from birth to adulthood and their relation with karyotpye distribution in Turkish girls with Turner syndrome.

To evaluate the anthropometric features of girls with Turner syndrome (TS) at birth and presentation and the effect of karyotype on these parameters. Data were collected from 842 patients with TS from 35 different centers, who were followed-up between 1984 and 2014 and whose diagnosis age ranged from birth to 18 years. Of the 842 patients, 122 girls who received growth hormone, estrogen or oxandrolone were excluded, and 720 girls were included in the study.

Genotypic and phenotypic features of the cystinosis patients from the South Eastern part of Turkey.

We have conducted this study for the purposes of demonstrating the spectrum of mutations and of identifying their effects on the phenotype, with a particular focus on the clinical course, prognosis and response to treatment. A total of 25 patients from 20 families, who have been treated and followed up after being diagnosed with cystinosis. Nine patients were identified with mutations of homozygous c.

Effects of methylphenidate on appetite and growth in children diagnosed with attention deficit and hyperactivity disorder.

The purpose of this study was to determine the levels of leptin, ghrelin, and nesfatin-1 to elucidate the causes of poor appetite and growth retardation in patients receiving methylphenidate therapy for attention deficit hyperactivity disorder. The study was performed on 89 male subjects; 48 patients and 41 healthy controls, aged 7-14 years. Following treatment, patients' leptin levels increased and ghrelin levels decreased while no significant change was found in nesfatin-1 levels.

Turner syndrome and associated problems in Turkish children: a multicenter study.

Objective: Turner syndrome (TS) is a chromosomal disorder caused by complete or partial X chromosome monosomy that manifests various clinical features depending on the karyotype and on the genetic background of affected girls. This study aimed to systematically investigate the key clinical features of TS in relationship to karyotype in a large pediatric Turkish patient population.

Methods: Our retrospective study included 842 karyotype-proven TS patients aged 0-18 years who were evaluated in 35 different centers in Turkey in the years 2013-2014.

Molecular analysis of PROP1, POU1F1, LHX3, and HESX1 in Turkish patients with combined pituitary hormone deficiency: a multicenter study.

To investigate the specific mutations in PROP1, POU1F1, LHX3, and HESX1 genes in patients with combined pituitary hormone deficiency (CPHD) in Turkey. Seventy-six patients with CPHD were included in this study. Based on clinical, hormonal, and neuro-radiological data, relevant transcription factor genes were evaluated by Sanger sequencing and multiplex ligation-dependent probe amplification.

Etiological evaluation of patients presenting with isolated micropenis to an academic health care center.

Objective: To evaluate etiology of the patients with micropenis presenting to a tertiary health care center.

Methods: In this prospective study all patients who were referred with a diagnosis of micropenis from October 2009 through October 2010, underwent a complete evaluation including measurement of stretched penile length.
