Olcay Güngör, Ahmet Kağan Özkaya, Fatih Temiz
The aim of this study was to evaluate the thyroid function alterations in a group of epileptic children taking antiepileptic drugs. The study included a total of 183 pediatric epilepsy patients, aged 15 months-16 years, comprising 114 patients treated with valproic acid, 69 patients treated with phenobarbital, and 151 age-matched healthy volunteers as the control group. Serum levels of thyroid hormones were measured before the beginning of the antiepileptic therapy and after 12 months of treatment. Thyroid-stimulating hormone levels were significantly higher in the 12th month of phenobarbital and valproic acid treatment...

Eosinophilic annular erythema (EAE) is an uncommon eosinophilic dermatosis. Clinically it is characterized by recurrent episodes of annular or figurative plaques. The histopathological study shows a perivascular inflammatory infiltrate in the superficial and deep dermis, composed of lymphocytes and eosinophils. It was originally described in children. We report an adult woman who presented with recurrent erythematous annular plaques on the trunk and extremities. A biopsy showed a mainly perivascular lymphocytic infiltrate with numerous eosinophils in the dermis...

Aim of this commentary is to report current knowledges on the main clinical and metabolic abnormalities which might be observed in children with longstanding and untreated subclinical hypothyroidism (SH) and to comment the most recent views about natural evolution of thyroid function in the cases with either idiopathic or Hashimoto's thyroiditis-related SH. On the basis of these preliminary remarks, the essential guidelines for an appropriate and tailored management of SH children are also proposed.

There is currently no consensus among the different scientific societies on screening for thyroid dysfunction in the first trimester of pregnancy. Indeed, diagnosis and treatment of subclinical hypothyroidism during pregnancy are controversial, as no cut-off value for thyrotropin (TSH) is universally accepted. TSH measurement may be influenced by different factors throughout pregnancy, but especially during the first trimester. The association between overt hypothyroidism during pregnancy and obstetric and perinatal complications is well established...

BACKGROUND: Studies on adults, have shown increased dispersion of QT and corrected QT (cQT), peak-to-end interval of the T wave (Tp-e), Tp-e/QT ratio and Tp-e/QTc ratio in subclinical hypothyroidism (SH), but there have been no paediatric studies MATERIALS AND METHODS: A total of 40 SH patients were compared with 40 healthy children in respect of serum thyroid stimulating hormone (TSH), serum free level of triiodothyronine (fT3) and free level of thyroxine (fT4). SH diagnosis was accepted as TSH above the laboratory accepted upper limit (> 4...

Hashimoto's thyroiditis is the most common cause of goiter and hypothyroidism among children and adolescents. Its clinical manifestations and course vary. The objective of this study was to review the clinical and evolutionary characteristics of Hashimoto's disease in the pediatric population. Clinical, analytical, ultrasound, epidemiological, and evolutionary data of patients with autoimmune thyroiditis seen at Hospital Universitario San Juan de Alicante between January 2010 and January 2016 were analyzed...

BACKGROUND: In the last two decades, several studies have examined the association between maternal thyroid hormone insufficiency during pregnancy and neurodevelopmental disorders in children and shown conflicting results. AIM: This systematic review aimed to assess the evidence for an association between maternal thyroid hormone insufficiency during pregnancy and neurodevelopmental disorders in children. We also sought to assess whether levothyroxine treatment for maternal thyroid hormone insufficiency improves child neurodevelopment outcomes...

Background: Subclinical hypothyroidism (SCH) is a commonly encountered entity in day-to-day clinical practice and has been associated with adverse cardiovascular risk profile in adults and children. Data on children and adolescents with SCH, from India, are limited. Materials and Methods: This study was a cross-sectional case-control study, conducted at a tertiary care center in Northeast India. Twenty-seven children and adolescents aged 11 ± 2.4 years with SCH and thyroid-stimulating hormone >7...

Antiseizure medications and dietary therapies have associated effects on the endocrine system. We provided an overview of the relationship between epilepsy treatment and bone health in children with epilepsy. Additionally, we discussed the effects of epilepsy treatment on other endocrine systems including thyroid function, growth, reproduction, and weight. The effect of epilepsy on bone health is multifactorial; there are direct and indirect effects of medication and dietary treatments as well as a decrease in physical activity, decreased sunlight exposure, decreased vitamin D levels, and additional comorbidities...

OBJECTIVE: To assess the natural history and progression of subclinical hypothyroidism and to study factors which help predict evolution of subclinical hypothyroidism into overt hypothyroidism. METHODS: Longitudinal study in 40 children (2-16 yrs) presenting with subclinical hypothyroidism in a tertiary care unit in Chennai, India. Patients showing evidence of overt hypothyroidism or thyroid stimulating hormone ≥ 15 mIU/mL during follow-up were started on thyroxine...

BACKGROUND: The appropriate age-related reference intervals for thyroid-stimulating hormone (TSH) and free thyroxine (FT4) are important in interpreting the results of thyroid function tests in children and adolescents. However, these reference intervals are scanty. This study aimed to establish the reference intervals for FT4, TSH, and thyroid peroxidase antibody (TPO Ab), and identify the epidemiological prevalence of thyroid dysfunction in a Korean pediatric population. METHODS: The data from a sample of 2042 children and adolescents aged 10-18years who underwent a nationwide Korean representative sampling and cross-sectional survey with blood collection for a thyroid function test using an electrochemiluminescence immunoassay were evaluated...

BACKGROUND: This study aims to assess the levels of visfatin in children and adolescents with autoimmune thyroiditis (AIT) and its relationship with disease-related variables. METHODS: The study included 84 children and adolescents with AIT and 84 healthy subjects. Measurements of fasting glucose, insulin, thyroid-stimulating hormone (TSH), free thyroxin (FT4), antithyroid peroxidase antibodies (TPOAb) and antithyroglobulin antibody (TgAb) were completed, with assessment of visfatin levels...

Importance: The incidence of thyroid disease in children with alopecia areata (AA) has been widely studied with no consensus on whether a true association with AA exists. In addition, screening practices for thyroid dysfunction in children with AA vary widely among clinicians. Objective: To reduce health care costs, eliminate unnecessary testing, and standardize clinical practices, we sought to characterize thyroid function in children with AA to establish guidelines for screening...

Down syndrome, caused by trisomy 21, is characterized by congenital abnormalities as well as mental retardation. From the neonatal stage through adolescence, patients with Down syndrome often have several complications. Thus, it is important to attain knowledge of the prevalence of these comorbidities in children with Down syndrome. We, therefore, evaluated the biochemical data, thyroid function, and anthropometric parameters, and analyzed the association among them in Japanese children and early adolescents with Down syndrome...

BACKGROUND: Autoimmune thyroid disease and thyroid dysfunction are common in adults receiving interferon-based treatment for chronic hepatitis C (CHC). Few data are available in children with CHC. This study is aimed to evaluate the appearance and timing of thyroid dysfunction and anti-thyroid autoimmunity in children with CHC treated with pegylated interferon-α-2b and ribavirin. METHODS: 61 otherwise healthy children with CHC, 3-17 years of age, infected perinatally and treatment naïve, receiving therapy with pegylated interferon-α-2b and ribavirin and 183 age- and sex-matched controls were included in a multicenter, prospective, case-control study...
