Background: Neonatal TSH screening program for congenital hypothyroidism (CH) in Central Serbia was introduced in 1983. Over the past three decades, increasing overall incidence rate of children with both permanent and transient forms of CH has been observed.Objective and hypotheses: The aim of the study was to compare incidence of CH in the first 16 years of screening (period 1) with the last 15 years of screening (period 2). We also investigated the im...

Background: Autoimmune’s thyroiditis (AT) is the most common cause of thyroid diseases in children and adolescents with a peak in early to mid-puberty (prevalence of 0.3–1.2%). Previous studies showed a high rates of familiarity for autoimmune disease (AD) and co-existing autoimmunity in AT subjects.Objective and hypotheses: Aim of our study is to investigate familiarity for AD and co-existing autoimmunity in a large cohort of pediatric AT pati...

Background: In recent years, studies have consistently demonstrated higher TSH concentrations in overweight/obese children and adults compared with normal weight individuals, whereas the levels of thyroid hormones in peripheral blood remain within normal range. This euthyroid hyperthyrotropinemia on the background of a worldwide increase in childhood obesity raises the question of whether subjects with this elevated TSH should be treated.Objective and hy...

Background: Neonatal thyrotoxicosis, a rare and life-threatening condition, is caused by transplacental transfer of thyroid stimulating immunoglobulins from mother to infant. While clinical features may include goitre, prominent eyes and poor weight gain, these may be absent in some cases. Early diagnosis and treatment of affected infants is critical.Objective: We report a case series of infants with neonatal thyrotoxicosis from two tertiary paediatric h...

Background: The cardinal feature of the resistance to thyroid hormone (RTH) is reduced responsiveness of target tissues to thyroid hormone action caused by thyroid hormone receptor β gene (THRB) mutations impairing hormone binding in the majority (90%) of cases. It results in elevated serum levels of free thyroxine (FT4) and triiodothyronine (FT3) associated with unsuppressed thyroid SH.Objective and hypotheses: The ai...

Background: Levothyroxine monotherapy is the treatment of choice for congenital hypothyroidism (CH). Recently, it was reported that levothyroxine monotherapy cannot guarantee euthyroidism in all athyreotic adult patients. A more physiological treatment than levothyroxine monotherapy was suggested to be required in some patients with hypothyroidism.Objective and hypotheses: To elucidate whether levothyroxine monotherapy is appropriate for all children wit...

Background: Anorexia nervosa is usually associated with lower levels of thyroid hormones especially suppressed TSH and T3 with normal T4 levels due to the effects of starvation on metabolism. We present two cases where the underlying eating disorder masked the thyroid dysfunction.Patient 1: 15-year-old girl with anorexia nervosa and BMI of 15.6 was noted to have suppressed TSH<0.1 mU/l, high normal T3–7.0 pmol/l ...

Background: Hypothyroidism is frequently associated with muscular disorders and sometimes with moderately elevated levels of muscle enzymes. On the other hand, neuromuscular manifestations are rarely the only symptoms/signs present. Kocher–Debré–Semelaigne syndrome is a myopathy of hypothyroidism in childhood characterized by muscular hypertrophy. Rhabdomyolysis due to hypothyroidism is very rare. A very high creatinine kinase level in the range seen with inflam...

Background: Congenital hypothyroidism (CH) is the commonest congenital endocrine disorder in the world and also the commonest most preventable cause of mental retardation. Screening is mandatory in developed countries, but none exists in sub-Saharan country. We present a preliminary report of the first Nigerian screening for CH.Objective and hypotheses: To screen normal newborn babies in different regions in Nigeria and to determine the normal range of T...

Introduction: Resistance to thyroid hormone (RTH) is a rare autosomal dominant condition characterised by tissue-specific insensitivity to thyroid hormone. In 85% of cases the disorder is associated with thyroid hormone receptor β (TRβ) gene mutations.Case report: A 2.6-year-old boy was referred to the Paediatric service with abnormal thyroid function tests (TFTs) (fT4 30.4 pmol/l; RR 12–26, fT3 10.2 pmol/l; RR 3.7&#1...

Background: The length of patient survival after cancer treatment is increasing and in some cases does not differ from the average life span in healthy individuals.Objective and hypotheses: The aim of the study is evaluation of thyroid function after oncologic treatment in children.Method: A group of 158 patients aged 16–25 who underwent oncologic treatment in childhood and the control group −66 children and young adults...

Background: Congenital hypothyroidism (CH) is a major target of new born screening. It has two major forms (permanent and transient) that have different prognoses.Objective and hypotheses: The purposes of this study were to assess the trends in incidence of permanent and transient CH in China, and to identify clinical variables that may help to distinguish these two forms of CH.Method: Newborns were screened for CH at Xinhua Hospit...

Background: Klippel–Feil syndrome (KFS) is characterized by congenital fusion of cervical vertebrae and has a prevalence of 1:50 000. The phenotypic expression is variable, sometimes presenting with extraskeletal symptoms.Case report: A girl was referred at the cronological age (CA) of 10.3 years with a suspected diagnosis of Turner syndrome, due to the presence of webbed neck and progressive deceleration of growth velocity. The girl, born in Russia...
