Insulin resistance is frequent in non-obese adolescent girls with irregular menstruation and/or clinical hyperandrogenism

Erden Fırat Deniz , Abacı Ayhan , Böber Ece , Demir Korcan

Background: Insulin resistance is predominantly associated with obesity. The euglycemic hyperinsulinemic clamp test, the gold standard for diagnosis of insulin resistance, has limited practical application. Although oral glucose tolerance test (OGTT) is generally used instead, there remains a need for more practical methods in outpatient clinics.Aim: The objective of this study is to assess the outcomes of the OGTT in no...

Elevated Anti-tissue Transglutaminase Antibodies in Children Newly Diagnosed with type 1 Diabetes do not Always Indicate Celiac Disease

Paketçi Ahu , Armagan Coskun , Erbas İbrahim Mert , Demir Korcan , Abaci Ayhan , Böber Ece

Introduction: The prevalence of celiac disease is 5–10 times higher in patients with type 1 diabetes mellitus (DM) than in the general population. Therefore, celiac serology should be screened intermittently in type 1 DM patients. However, anti-tissue transglutaminase (anti-TTG) antibody elevation may be detected incidentally at the time of type 1 DM diagnosis and regress spontaneously during follow-up, without medical or dietary interventions.<p clas...

Initial Neutrophil/Lymphocyte and Lymphocyte/Monocyte Ratios Can Predict Future Insulin Need in Newly Diagnosed Type 1 Diabetes Mellitus

Erbaş Ibrahim Mert , Hajikhanova Aygun , Besci Ozge , Acinikli Kubra Yuksek , Demir Korcan , Bober Ece , Abacı Ayhan ,

Background: The exact mechanism of the partial clinical remission in type 1 diabetes mellitus (T1DM) has not been elucidated yet. The severity of the inflammation at the time of diagnosis may have an impact on the occurrence or duration of this phase.Objective: We aimed to investigate the relationship between hematological inflammatory parameters at the time of diagnosis in children and adolescents with T1DM and the need...

Introduction: CPHD is characterized by impaired production of GH and one or more other pituitary hormones. Genetic defects causing CPHD typically result in insufficient anterior pituitary gland development.Aim: The aim of the study is to determine the genetic etiologies that lead tocombined hormone deficiencies. Todetermine phenotype genotype relationship with or without extra-pituitary anomalies.<...

Introduction: The most common causes of hyperthyroidism in the pediatric age group are autoimmune conditions (Graves' disease or Hashitoxicosis). Hyperfunctioning thyroid carcinomas are rarely reported. In this case report, we present a 17-year-old girl who was diagnosed with papillary thyroid carcinoma upon testing for hyperthyroidism.Case: A 17-year-old girl had presented to another center with a 1-month history of...

A Rare Cause of Hypogonadotropic Hypogonadism: FGFR1Mutation

Mert Erbaş İbrahim , Paketçi Ahu , Acar Sezer , Kotan Damla , Demir Korcan , Abaci Ayhan , Böber Ece

Introduction: Mutations in FGFR1, which is involved in formation and migration of neurons responsible for the production of gonadotropin-releasing hormones, may either cause isolated hypogonadotropic hypogonadism (HH) or Kallmann syndrome (KS). In addition, FGFR1mutations were reported in 2.7% of the cases with multiple pituitary hormone deficiency.Case: A 16-year-old male was referred to our clinic...
