Sadek J. Attention Deficit Hyperactivity Disorder Misdiagnosis: Why Medical Evaluation Should Be a Part of ADHD Assessment. Brain Sci 2023; 13:1522. [PMID: 38002482 PMCID: PMC10669410 DOI: 10.3390/brainsci13111522] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/15/2023] [Revised: 10/19/2023] [Accepted: 10/27/2023] [Indexed: 11/26/2023] Open
Abstract
INTRODUCTION Attention deficit hyperactivity disorder (ADHD) is a neurodevelopmental disorder that interferes with multiple aspects of daily functioning and is associated with impairments in several domains. It may affect academic, educational, vocational, social, emotional, interpersonal, and health domains, and worsen risks to health outcomes. OBJECTIVE To identify and discuss medical conditions that commonly present with symptoms resembling ADHD. METHOD This review is selective and not systematic. It is conducted through a focused literature search through PubMed, Google Scholar, and EMBASE. Search term included "ADHD misdiagnosis", "medical conditions with ADHD like symptoms", "ADHD AND medical problems". EXCLUSION giftedness, high IQ, and any article that does not list medical conditions. The limits applied were the following: the work must have been published in the past 20 years, be on humans, and be in the English language. RESULTS There are several medical conditions that can be misdiagnosed as ADHD and may show a similar presentation to ADHD, particularly with inattentive symptoms. Examples include, but are not limited to, absence seizure disorder, diabetes, thyroid dysfunction, sleep deprivation, post-concussion states, inflammatory bowel disease, iron deficiency states and anemia, and disordered breathing. CONCLUSIONS Our review suggests that a thorough medical evaluation should be conducted prior to the diagnosis of ADHD. Allied health professionals and psychologists who diagnose ADHD should seek medical clearance from a physician prior to making the ADHD diagnosis in order to reduce misdiagnosis rates and improve patient outcomes. ADHD diagnosis should follow guidelines and be carried out under a systematic standardized approach. A full medical evaluation should be conducted to assess for medical conditions that may look like ADHD or be associated with ADHD.

Abstract
Acquired hypothyroidism is generally also referred to as juvenile hypothyroidism. Hypothyroidism is due to the deficient secretion of thyroid hormones causing metabolic and neurological sequelae at the cellular level. It can present as overt hypothyroidism wherein the thyroid hormones (T4 and T3) secretion fall and thyrotropin (TSH) rises. Acquired hypothyroidism frequently presents between 9 and 11 y of age and is rarely seen before 4 y of age. Approximately 80% of the children and adolescents are asymptomatic at the time of diagnosis. Children with moderate to severe hypothyroidism often present for evaluation of poor growth, constipation, lethargy and/or dry skin. A detailed history and examination will provide us with enough clues for diagnosing hypothyroidism. Primary hypothyroidism can be diagnosed with raised TSH with subnormal levels of T3 and T4. Titres of thyroid antibodies - Anti-thyroperoxidase (TPO) and anti-thyroglobulin (ATG) antibodies, will be high in autoimmune hypothyroidism. Subclinical hypothyroidism is diagnosed with mildly elevated or high normal levels of TSH with free T4 being in the normal range. Insufficient secretion of thyrotropin from the pituitary causes central hypothyroidism. Acquired hypothyroidism is treated by replacement with levothyroxine. Regular monitoring of thyroid profile is necessary for adjusting doses of levothyroxine. Close monitoring and individualization of levothyroxine therapy is essential for normal growth and development of the child.

Abstract
BACKGROUND Delayed diagnosis of hypothyroidism may result in atypical presentations. Here, we report a case with decreased serum level and activity of von Willebrand factor due to untreated profound hypothyroidism. OBSERVATION A 9-year-old girl, presented with prolonged gingival bleeding after dental extraction. Clinical findings of the case were consistent with hypothyroidism, and the laboratory workup results revealed decreased serum level and activity of von Willebrand factor associated with profound hypothyroidism. Restoration of euthyroidism normalized the coagulation parameters. CONCLUSION Delayed diagnosis of hypothyroidism may lead to atypical presentations such as bleeding diathesis. Profound hypothyroidism should be considered in the differential diagnosis of acquired von Willebrand disease to avoid undue treatment.

Evaluation of catch-up growth in severe pediatric Hashimoto's hypothyroidism. Arch Pediatr 2023; 30:142-148.

Abstract
BACKGROUND We aimed to evaluate catch-up growth in children with severe Hashimoto's hypothyroidism (HH) after thyroid hormone replacement therapy (HRT). METHODS A multicenter retrospective study was conducted including children referred for growth slowdown that led to the diagnosis of HH between 1998 and 2017. RESULTS A total of 29 patients were included, with a median age of 9.7 years (13-172 months). Median height at diagnosis was -2.7 [-4.6; -0.1] standard deviation score (SDS), with a height loss of 2.5 [0.7; 5.4] SDS compared to height before growth deflection (p<0.0001). At diagnosis, the median TSH level was 819.5 mIU/L [100; 1844], the median FT4 level was 0 pmol/L [undetectable; 5.4], and the median anti-thyroperoxidase antibody level was 1601 UI/L [47; 25,500]. In the 20 patients treated only with HRT, there were significant differences between height at diagnosis and height at 1 year (n = 19, p<0.0001), 2 years (n = 13, p = 0.0005), 3 years (n = 9, p = 0.0039), 4 years (n = 10, p = 0.0078), and 5 years (n = 10, p = 0.0018) of treatment but not in the case of final height (n = 6, p = 0.0625). Median final height was -1.4 [-2.7; 1,5] SDS (n = 6), with a significant difference between height loss at diagnosis and total catch-up growth (p = 0.003). The other nine patients were also given growth hormone (GH). They were smaller at diagnosis (p = 0.01); however, there was no difference in final height between those two groups (p = 0.68). CONCLUSION Severe HH can lead to a major height deficit, and catch-up growth seems to be insufficient after treatment with HRT alone. In the most severe cases, administration of GH may enhance this catch-up.

Abstract
INTRODUCTION Severe acquired hypothyroidism in childhood is a rare condition, mostly caused by autoimmune thyroiditis. Scarce and inconsistent data based on small patient numbers exist concerning its impact on growth in height. METHODS Patient files at a single centre university hospital over 8 years were retrospectively reviewed. We identified 43 patients (mean age 10.6 years, 3.3-15.25, 59% prepubertal, 88% females) in a cohort of children older than 3 years with an initial TSH>30 mIU/l and reduced T4 or fT4; congenital and drug-induced hypothyroidism were excluded. RESULTS All patients had signs of autoimmune thyroiditis (93% positive autoantibodies, 95% typical ultrasonography, 63% goiter). Median TSH was 100 mIU/l [0.3-4 mIU/l]), median fT4 3.55 pg/ml [8-19 pg/ml], median T4 2.85 µg/dl [5.3-11 µg/dl]. Presenting symptoms included goiter (26%), tiredness (23%), weight gain (19%), and growth retardation (19%). The diagnosis was made incidentally in 26% patients. In 75% growth was retarded (median height standard deviation score (SDS)-0.55), in 17% height SDS was<-2 at diagnosis. Midparental height SDS at diagnosis correlated significantly with T4 and fT4 (r=0.77, p=0.0012 and r=0.53, p=0.021 respectively). Catch-up growth under T4 substitution was significantly greater in prepubertal than in pubertal children (p 0.049). CONCLUSION This so far largest pediatric cohort with severe acquired hypothyroidism confirms a serious impact on growth which, however in most cases, showed a certain catch-up growth after adequate L-thyroxine therapy. The pubertal state seems to be important for catch-up growth. A significant number of patients were not diagnosed clinically, although affected by severe hypothyroidism.

Abstract
CONTEXT Thyroid ultrasound screening is recommended in children with PTEN hamartoma tumor syndrome (PHTS) due to increased risk of thyroid neoplasia, but the natural history of thyroid disease in children with PHTS is unclear. OBJECTIVE Determine the prevalence and natural history of thyroid disease in children with PHTS. METHODS Retrospective cohort study (1998-2019) in an academic pediatric hospital of individuals with genetically confirmed PHTS diagnosed before age 19 years. Clinical, thyroid ultrasound, and laboratory characteristics are described. Primary outcomes were the prevalence of thyroid nodules ≥10 mm diameter and time course and risk factors for nodule development assessed by Cox regression analysis. Secondary outcomes included thyroid nodule requiring biopsy, other ultrasound findings, and prevalence of autoimmune thyroid disease. RESULTS Among 64 subjects with PHTS, 50 underwent thyroid ultrasound. A thyroid nodule ≥10 mm was diagnosed in 22/50 (44%) subjects at median (range) age 13.3 (7.0-22.9) years. Nodules were diagnosed earlier in females than in males (10.8 [7.0-17.9] vs 14.2 [9.9-22.9] years, P = .009). In multivariate analysis, risk of thyroid nodules was significantly associated with female sex (hazard ratio 2.90, 95% CI 1.16-7.27, P = .02) and inversely associated with the presence of neurologic findings of PHTS (HR 0.27, 95% CI 0.10-0.69, P = .007). Abnormal-appearing lymph nodes with echogenic foci were observed by ultrasound in 20% of subjects, but these were not associated with malignancy. Autoimmune thyroid disease was present in 10/33 (30.3%) of subjects in whom it was assessed. CONCLUSION Thyroid disease is common in children with PHTS. This study supports current consensus recommendations for ultrasound screening.

Abstract
INTRODUCTION Juvenile hypothyroidism (JH) can have deleterious effects on growth, pubertal development, and scholastic performance of children. In India, there is a paucity of data on acquired hypothyroidism in children, in contrast to congenital hypothyroidism. Our objective was to assess the profile of JH in a referral clinic from eastern India. MATERIALS AND METHODS For this study, 100 patients with documented acquired hypothyroidism (subclinical and overt) (aged <18 years), from eastern India, were evaluated retrospectively. Evaluation included history as well as clinical, biochemical, and ultrasonography parameters. RESULTS Out of the 100 participants, 74% had overt hypothyroidism (OH), while 26% had subclinical hypothyroidism (SCH). The majority of the participants were females (66%). The mean age at detection was 8.95 ± 3.96 years in the SCH group and 8.38 ± 3.29 years in the OH group. A family history of thyroid disorder and/or goiter was present in 35% of the patients. Goiter was the most common presentation in both SCH and OH, with overall prevalence of 58%. Height below 3rd percentile was significantly higher (28%) in OH group compared to 4% in SCH group. Five percent of OH subjects were obese. Worsening school performance was reported in only 9% of subjects. Only 4% (all males) presented with delayed puberty, while one female (1%) presented with precocious puberty. Sixty-four percent of OH group were TPOAb positive compared to only 15% in SCH group. Five percent of our study population had type-1 diabetes mellitus (T1DM) and 7% had Down syndrome (DS). CONCLUSION In our study, JH showed significantly higher female preponderance and TPOAb positivity in OH group, in comparison to SCH group. Family history of thyroid disorder and/or goiter was present in a significant proportion of patients. Goiter was the most common presentation of JH. Height deceleration, weight gain, and fatigue were the other common presentations. Prevalence of short stature was significantly higher in OH group. Interestingly, in contrast to prevalent notion, only 5% of OH were obese and worsening school performance was observed to be rare. Puberty disorders (both delayed and precocious) may occur in JH as seen here. Because of strong association, those with T1DM or DS should be screened for JH and vice versa in TIDM.

Abstract
Background: Autoimmune thyroiditis (AIT) is the most common cause of acquired hypothyroidism in children. The natural outcome of AIT in childhood has been reported previously however follow-up duration is generally short and results variable. Objectives: To characterize clinical and biochemical findings at presentation of AIT, evaluate long-term outcomes and assess which factors at presentation predict evolution over time. Study cohort: 201 children under 18 years of age at presentation (82% female) were enrolled. Subjects were divided into five subgroups according to thyroid stimulating hormone (TSH) level at referral. Results: Mean follow-up was 8.1 years (range 0-29 years). At presentation, 34% of patients had overt hypothyroidism, 32% subclinical hypothyroidism (SCH), 16% compensated hypothyroidism, 14% were euthyroid, and 3.7% had Hashitoxicosis. Children with overt hypothyroidism were younger (10.6 vs. 13.2 years) and had higher thyroid peroxidase antibody titers. At the time of the study, levothyroxine (LT4) therapy was required in 26% of children who were euthyroid at presentation, 56% of SCH patients, 83-84% of those with TSH above 10 mIU/L, and 57% of those with Hashitoxicosis. Over the years, 16% of children presenting with overt hypothyroidism stopped therapy. Free T4 at presentation was the only predictor of outcome over time. Conclusions: Our findings suggest that only 26% children who were euthyroid at presentation developed hypothyroidism, whereas over 50% of those with SCH went on to require treatment. Of those presenting with overt hypothyroidism, 16% recovered with time. The only predictive parameter for LT4 therapy at the end of the study was free T4 levels at presentation. Long-term follow-up is required to determine ongoing therapy needs and screen for additional autoimmune diseases.

Abstract
Background Thyroid dysfunction is the most common hormonal abnormality in obesity. It should actually be considered as an adaptation response to fat excess. However, little has been reported on the morphology of the thyroid gland, and no data regarding the relationship between thyroid gland changes and metabolic parameters are available in obese adolescents. Objective The study aimed to evaluate the frequency of non-autoimmune thyroiditis in obese adolescents and compare the metabolic status of patients with or without thyroiditis. Methods A total of 218 obese children and 49 age-matched control healthy children were included. Thyroid ultrasonography (USG) was performed in all participants, as well as thyroid hormone levels, thyroid antibodies (Abs), lipid profile, homeostasis model assessment of insulin resistance (HOMA-IR) and high-sensitivity C-reactive protein (HsCRP) were determined. Obese children were divided into three groups according to the presence of thyroid autoantibodies and USG findings of thyroiditis (Group-1: Abs [-], normal thyroid morphology/Group-2: Abs [+], abnormal thyroid morphology/Group-3: Abs [-], abnormal thyroid morphology). The relationship between body mass index, metabolic parameters and thyroid gland status was analyzed. Results Seventy-two of 218 obese patients (33%) had non-autoimmune thyroiditis (Group-3). The rate of insulin resistance was significantly higher in Group-3 than in Group-1 (p = 0.024). Similarly, the frequency of metabolic syndrome (MS) was higher in Group-3 (44.3%) than in Group-1 (27.1%) (p = 0.014). Conclusions Obese adolescents with non-autoimmune thyroiditis had a higher incidence of insulin resistance. This finding supported the hypothesis that insulin resistance may have an effect on thyroid morphology. Further randomized trials investigating this relationship are required.

Hypothesis: Persistently normal TSH levels may be used to recognize patients with transient forms of hypothyroidism and to suggest treatment withdrawal. Med Hypotheses 2018; 116:122-123.

Abstract
There are no text-book recommendations on when or if treatment should or could be stopped in patients with a diagnosis of hypothyroidism, and these patients usually receive lifelong thyroxine therapy (despite the fact that some of them may have forms of transient hypothyroidism that will later recover function). Since TSH fluctuations during thyroxine treatment are common and a lack of this fluctuation might be used to identify patients who no longer need thyroxine treatment, we hypothesize that by offering patients with persistently controlled TSH levels a withdrawal trial of thyroxine treatment we may identify those who no longer need life-long treatment.

Abstract
ᅟ Aim of this commentary is to summarize the salient literature views on the relationships between presentation and evolution patterns of thyroid function in children with Hashimoto’s thyroiditis (HT). According to the most recent reports, children with HT and subclinical hypothyroidism (SH) are more prone to the risk of developing severe thyroid dysfunctions over time, if compared to those presenting with euthyroidism. In contrast, children presenting with HT and either overt or subclinical hyperthyroidism are incline to exhibit a definitive resolution of the hyperthyroid phase within some months, although there is a wide variability between the different individuals. The natural history of frank hypothyroidism in the children with HT has never been investigated so far, since in these cases an immediate onset of replacement treatment is mandatory. Conclusions 1) a deterioration of thyroid status over time may be observed especially in the children presenting with SH, but also in those presenting with euthyroidism; 2) a definitive resolution of the hyperthyroid phase is generally observed in those presenting with either overt or subclinical hyperthyroidism.

Abstract
Hashimoto's thyroiditis (HT) is the most common cause of thyroid disease in children and adolescents. Along with significant modifications of thyroid function, HT in pediatric age can be accompanied by relevant thyroid structural alterations. Over time, benign thyroid nodules, carcinoma and, rarely, primary non-Hodgkin lymphoma can develop. However, the relationships between HT and neoplasms are poorly defined. The main aim of this paper is to discuss what is presently known regarding the coexistence of HT and thyroid tumors. Moreover, we attempt to define the pathogenesis of cancer development in children with HT. Literature analysis showed that despite its rarity and relatively promising prognosis, thyroid cancer is associated with HT. Although not all reasons for the coexistence of these diseases are clearly defined, children with HT should be considered at higher risk for thyroid cancer development. Strict correlations between high levels of serum TSH and anti-thyroid antibodies with cancer must be remembered. The same is true for the presence of nodules, especially if multiple nodules are present and ultrasonography and thyroid fine needle aspiration cytology should be promptly used in uncertain cases.

Determinants of levothyroxine dose required to achieve euthyroidism in pediatric population-a hospital-based prospective follow-up study. Eur J Pediatr 2017; 176:1027-1033. [PMID: 28578454 DOI: 10.1007/s00431-017-2930-z] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/08/2017] [Revised: 05/06/2017] [Accepted: 05/10/2017] [Indexed: 10/19/2022]
Abstract
UNLABELLED We analyzed the relation of pretreatment anthropometric measures and serum thyrotropin (TSH) with the levothyroxine requirement. Children (3-18 years) brought to endocrine clinic with newly diagnosed acquired primary hypothyroidism were enrolled consecutively and prospectively with follow-up (July 2014 to April 2016). Children were started on levothyroxine, and dose was adjusted at regular intervals until achieved euthyroidism (serum TSH 0.4 to 4.5 mIU/L). The relationship of age, gender, height, weight, and serum TSH with levothyroxine dose was analyzed by univariate and multivariate regression analysis. Data of 51 children (42 girls and 9 boys) was used for the analysis. Age, weight, height, and serum TSH had significant correlation with levothyroxine daily dose based on weight (D/W) and dose based on BSA (D/BSA). Log10 TSH and gender explained ∼60% absolute levothyroxine daily requirement. The final model built with height and serum TSH predicted ∼85% of D/W and ∼80% of D/BSA. CONCLUSION Pretreatment height and serum TSH can be used to determine levothyroxine dose needed to achieve euthyroidism in a newly diagnosed acquired primary hypothyroidism in children. What is Known: • The starting dose of levothyroxine is currently recommended based on the age of children. What is New: • In pediatric population, the effect of age on levothyroxine daily dose requirements can be explained by pretreatment height. • Pretreatment serum TSH level is an important predictor of levothyroxine daily dose in children with newly diagnosed primary hypothyroidism.

Abstract
The goals of this undertaking were to assess the outcomes of thyroid screening tests and adherence to thyroid screening guidelines across five Down syndrome (DS) specialty clinics in various states. Data related to thyroid screening were collected for 663 individuals across five clinics specializing in the comprehensive care of individuals with DS for a period of 1 year. Of the 663 participants, 47.7% of participants had a TSH and free T4 ordered at their DS specialty clinic visit. Approximately 19.0% (60/316) had a new thyroid disorder diagnosis made. We conclude that a sizable proportion of the patients with DS are not up-to-date on current guidelines when they present to a DS specialty clinic, while adherence to thyroid screening guidelines helps facilitate early diagnoses. Hypothyroidism is prevalent in the population, consistent with reported literature. DS specialty clinics can help patients stay current on screening guidelines.

Abstract
BACKGROUND Levothyroxine (L-T4) treatment of euthyroid children with Hashimoto thyroiditis (HT) is a controversial issue. PATIENTS AND METHODS We conducted a prospective, randomized, controlled clinical trial. Out of 79 identified euthyroid patients, 59 started the study; 25 patients (21 female, 4 male; age: 11.8 ± 2.3 years) received L-T4 at a mean dose of 1.6 µg/kg (SD, 0.8) daily, and 34 (27 female, 7 male; age: 12.6 ± 1.2 years) were not treated. Patients developing subclinical hypothyroidism during follow-up (n = 13) were treated with L-T4 and removed from the observation group. As the main outcome measures, thyroid gland volume (determined by ultrasound) as well as serum levels of TSH, free T4, and antibodies against thyroid peroxidase and thyroglobulin were assessed every 6 months for 36 months. RESULTS At the start, the mean thyroid volume (standard deviation score, SDS) was 2.5 in the treatment group and 1.6 in the observation group. There was a constant decline in mean thyroid volume (SDS) from 2.13 (month 12) to 1.12 (month 30) in the treated group, with a delta thyroid volume of -1.01 SDS. In the observation group, the mean delta thyroid volume increased to +0.27 SDS. The change of the delta thyroid volume was statistically significantly different between both groups during the 12- and 30-month time points (p < 0.05). L-T4 had no effect on thyroid function and serum thyroid antibodies. CONCLUSIONS L-T4 treatment can decrease the thyroid volume in euthyroid children with HT, but the effect is limited to a definite time period.

Abstract
Hashimoto's encephalopathy (HE) is a rare not well understood, progressive and relapsing multiform disease, characterized by seizures, movement disorders, subacute cognitive dysfunction, psychiatric symptoms and responsiveness to steroid therapy. The disorder is generally associated with thyroid diseases and the most common feature is the presence of anti-thyroperoxidase antibodies (TPOAb). Patients are usually euthyroid or mildly hypothyroid at presentation. All age groups can be affected. The pathophysiology is still unclear, especially the link between elevated serum TPOAb and the encephalopathy. Most reported cases occurred in women and girls. Unspecific symptoms, non-pathognomonic laboratory neurophysiology and neuroimaging features make its diagnosis a real challenge for clinicians. The case of a 16 year old boy, with a clinical picture of HE associated with hypothyroidism, demonstrating an excellent response to high dose steroids is presented together with a systematic review of the literature.

Abstract
BACKGROUND Hashimoto's thyroiditis (HT) is the commonest cause of acquired hypothyroidism in children and adolescents in iodine non-endemic areas. The genetic analysis in HT shows two types of susceptibility genes-immune regulatory and thyroid specific genes. The exact genotype-phenotypic correlations and risk categorization of hypothyroid phenotypes resulting from these known mutations are largely speculative. The genetic studies in pediatric HT are very sparse from Indian sub-continent. In this context, we analysed the prevalence of TPO, NIS and DUOX2 gene mutations along with genotype-phenotype correlations in hypothyroid children with HT. METHODS This is inter-disciplinary study conducted by collaboration between a tertiary care endocrinology hospital, biochemistry department of a teaching medical institute and genetics lab. In this prospective study, we employed 8 sets of primers and screened for 142 known single nucleotide polymorphisms in TPO, NIS, DUOX2 genes. The subjects were children and adolescents with hypothyroidism due to HT. Congenital hypothyroidism, iodine deficiency and dyshormonogenetic hypothyroidism cases were excluded. RESULTS We detected 8 mutations in 7/20 (35%) children in the entire cohort (6 in NIS and 2 in TPO genes. No mutations were observed in DUOX2 gene. All our mutations were localized in introns and we found none in exons. Except for bi-allelic, synonymous polymorphism of TPO gene in child No. 18, all other mutations were heterozygous in nature. Genotype-phenotype correlations show that our mutations significantly expressed the presence of associated autoimmune manifestations and existence of family history. Clinical phenotypes of painful thyroiditis, severity of hypothyroidism and absence of goiter were statistically significant in the presence of these mutations. But, they could not reach significance on multivariate analysis. CONCLUSIONS NIS gene followed by TPO mutations appears to be most prevalent mutations in HT amongst South Indian children and these mutations significantly influenced phenotypic expressions such as severity of hypothyroidism, goiter, auto-immune manifestations and family history.

Abstract
UNLABELLED Aim of this commentary is to summarize the salient literature news on the relationships between autoimmune thyroid diseases (ATDs) and either Down syndrome (DS) or Turner syndrome (TS).According to literature reports both Hashimoto's thyroiditis (HT) and Graves' disease (GD) are more frequent in children with DS or TS than in those without these chromosomopathies.An up-regulation of proinflammatory cytokines might be responsible for the enhanced susceptibility of TS children to ATDs, whereas a dysregulation of immune system may favor the development of ATDs in DS.In TS children biochemical presentation of HT is less severe than in peer controls. In both DS and TS GD picture at the time of diagnosis is not significantly different than in the pediatric general population.The evolution over time of GD in DS and TS does not differ from that observed in the pediatric general population, whereas the evolution of HT in both TS and DS is more severe than in girls without these chromosomopathies. CONCLUSIONS The association with TS or DS is able to affect both epidemiology and course of ATDs by conditioning: a) an increased susceptibility to these disorders; b) a less severe biochemical presentation and a more severe evolutive pattern of HT in TS girls; c) a more severe biochemical presentation and evolution of HT in DS patients.

Abstract
Hashitoxicosis is an initial, transient, hyperthyroid phase that rarely affects patients with Hashimoto thyroiditis. We present here an unusual case of a child with Hashimoto thyroiditis and recurrent hyperthyroidism. A 4 yr 6/12 old male was diagnosed by us with autoimmune subclinical hypothyroidism (normal free T4, slightly elevated TSH, and elevated TG antibody titer). Two years and 6/12 later he experienced increased appetite and poor weight gain; a laboratory evaluation revealed suppressed TSH, elevated free T4, and normal TSI titer. In addition, an I123 thyroid uptake was borderline-low. A month later, the free T4 had normalized. After remaining asymptomatic for 3 years, the patient presented again with increased appetite, and he was found with low TSH and high free T4. Within the following 3 months, his free T4 and TSH normalized. At his most recent evaluation, his TSH was normal and the free T4 was borderline-high; the TG antibody titer was still elevated and the TSI titer was negative. To our knowledge, this is the first patient reported with Hashimoto thyroiditis and recurrent hyperthyroidism. This case exemplifies the variability of the manifestations and natural history of Hashimoto thyroiditis and supports the need for a long-term evaluation of patients with autoimmune thyroid disease.

Abstract
In this article, several aspects of childhood obesity are discussed, including epidemiology, associated metabolic complications, management strategies, and therapy with particular attention to the impact of obesity on the liver, resulting in nonalcoholic or metabolic fatty liver disease. The deleterious effects of obesity on the liver and health overall can be significantly impacted by a culture that fosters sustained nutritional improvement and regular physical activity. The current evidence is summarized supporting pharmacologic, behavioral, and dietary interventions for the management of obesity and fatty liver disease in children.

Abstract
Hashimoto thyroiditis (HT), now considered the most common autoimmune disease, was described over a century ago as a pronounced lymphoid goiter affecting predominantly women. In addition to this classic form, several other clinico-pathologic entities are now included under the term HT: fibrous variant, IgG4-related variant, juvenile form, Hashitoxicosis, and painless thyroiditis (sporadic or post-partum). All forms are characterized pathologically by the infiltration of hematopoietic mononuclear cells, mainly lymphocytes, in the interstitium among the thyroid follicles, although specific features can be recognized in each variant. Thyroid cells undergo atrophy or transform into a bolder type of follicular cell rich in mitochondria called Hürthle cell. Most HT forms ultimately evolve into hypothyroidism, although at presentation patients can be euthyroid or even hyperthyroid. The diagnosis of HT relies on the demonstration of circulating antibodies to thyroid antigens (mainly thyroperoxidase and thyroglobulin) and reduced echogenicity on thyroid sonogram in a patient with proper clinical features. The treatment remains symptomatic and based on the administration of synthetic thyroid hormones to correct the hypothyroidism as needed. Surgery is performed when the goiter is large enough to cause significant compression of the surrounding cervical structures, or when some areas of the thyroid gland mimic the features of a nodule whose cytology cannot be ascertained as benign. HT remains a complex and ever expanding disease of unknown pathogenesis that awaits prevention or novel forms of treatment.

Abstract
BACKGROUND/AIMS Vitiligo is considered to be an autoimmune disease and is known to be associated with other autoimmune diseases, particularly affecting the thyroid. In children and adolescents this association has been reported in only a few studies, with varying results. The aim of this study was to examine thyroid function and prevalence of thyroid autoimmunity in children and adolescents with vitiligo and to investigate the utility of screening. METHODS Two hundred and sixty patients with vitiligo were enrolled. Plasma TSH, FT4 and anti-thyroid peroxidase (TPO) antibody concentrations were measured. The prevalence of thyroid dysfunction and autoimmunity were compared to the general healthy paediatric population. RESULTS Autoimmune thyroiditis (AIT) with thyroid hormone disturbances was diagnosed in 16 patients (6.2%). This is significantly higher than the prevalence reported in the general healthy paediatric population. Increased levels of anti-TPO antibodies (= 30 kU/l), without thyroid hormone disturbances, were found in 27 patients (10.5%). CONCLUSION The prevalence of AIT in children and adolescents with vitiligo is significantly higher than in the general population. It may be advantageous to screen thyroid function and antibody levels in all paediatric patients with non-segmental vitiligo. To strengthen recommendations on screening, research on the burden for patients and cost-effectiveness is needed.

Abstract
Aim of this survey is to report the most recent views about Hashimoto’s thyroiditis (HT) natural history according to the different presentations. In children presenting with either euthyroidism or subclinical hypothyroidism HT spontaneous course is frequently characterized by a trend towards deterioration of thyroid function, whereas in those presenting with overt hyperthyroidism a definitive resolution of hyperthyroid phase is to be expected. Another possible even though unusual outcome of HT is the conversion to Graves’ disease.

Abstract
Background While it is recognized that patients sometimes recover from autoimmune hypothyroidism, little is known about how rapidly this may occur. Case reports Two 13 year old girls had severe primary hypothyroidism (total T4 14.2 nmol/L with TSH 468 miU/L and total T4 7.7 nmol/L with TSH 183 miU/L) accompanied by goiter and positive thyroid peroxidase antibodies. There were delays in starting thyroid hormone replacement, and complete reversal of hypothyroidism was documented within 2 months in both cases. One of the girls had recurrence of severe hypothyroidism after being euthyroid for 18 months. Review of literature There are few published studies which have looked systematically at reversibility of acquired hypothyroidism, but one Japanese study found that recovery from autoimmune hypothyroidism may occur within weeks. Other causes of primary hypothyroidism (TSH-blocking antibodies, iodine excess, medications) seem less likely, so this probably represents rapid spontaneous reversal of autoimmune hypothyroidism. Conclusion Patients with severe autoimmune hypothyroidism may have spontaneous normalization of thyroid tests within weeks to months after diagnosis. This suggests that reevaluating the need for thyroid hormone replacement in selected patients with persistently normal TSH during therapy should be considered.

Abstract
OBJECTIVE The natural history of Hashimoto's thyroiditis (HT) and isolated hyperthyrotropinaemia (IH) is not well defined. We therefore studied the natural course of patients with HT and IH and looked for possible prognostic factors. DESIGN This is retrospective cross-sectional study. PATIENTS Three hundred and twenty-three patients with HT (88 boys and 235 girls) and 59 with IH (30 boys and 29 girls), mean age 9·9 ± 3·8 years were included in the study. When first examined, 236 of the children with HT had a normal TSH (G0) and in 87, it was elevated but <100% of the upper limit (G1). All IH subjects had elevated TSH. Potential risk factors for thyroid failure were evaluated after 3 years and included the presence or familiarity for endocrine/autoimmune diseases, premature birth, signs and symptoms of hypothyroidism, TSH levels, antithyroid antibodies and thyroid volume. RESULTS HT: Of those with HT, 170 G0 patients remained stable, 31 moved to G1 and 35 to G2 (hypothyroidism). Thirty-six G1 children moved to G0, 17 remained stable and 34 moved to G2. Of patients with IH: 23 normalized, 28 remained stable and eight became overtly hypothyroid. In patients with HT, the presence of coeliac disease, elevated TSH and thyroid peroxidase antibodies (TPOAb) increased the risk of developing hypothyroidism by 4·0-, 3·4- and 3·5-fold, respectively. The increase in TSH levels during follow-up was strongly predictive of the development of hypothyroidism. In patients with IH, no predictive factor could be identified. CONCLUSIONS Coeliac disease, elevated TSH and TPOAb at presentation and a progressive increase in TSH are predictive factors for thyroid failure in HT patients.

How does age at onset influence the outcome of autoimmune diseases? Autoimmune Dis 2011; 2012:251730.

Abstract
The age at onset refers to the time period at which an individual experiences the first symptoms of a disease. In autoimmune diseases (ADs), these symptoms can be subtle but are very relevant for diagnosis. They can appear during childhood, adulthood or late in life and may vary depending on the age at onset. Variables like mortality and morbidity and the role of genes will be reviewed with a focus on the major autoimmune disorders, namely, systemic lupus erythematosus (SLE), rheumatoid arthritis (RA), multiple sclerosis (MS), type 1 diabetes mellitus (T1D), Sjögren's syndrome, and autoimmune thyroiditis (AITD). Early age at onset is a worst prognostic factor for some ADs (i.e., SLE and T1D), while for others it does not have a significant influence on the course of disease (i.e., SS) or no unanimous consensus exists (i.e., RA and MS).

Abstract
OBJECTIVE The aim of this study was to evaluate the clinical course of Hashimoto's thyroiditis (HT) in children and adolescents and the effects of levothyroxine therapy on the clinical course and laboratory findings. METHODS The clinical and laboratory data of 101 patients with HT at presentation and during a three-year follow-up period were retrospectively evaluated using patient records. RESULTS The mean age of the patients at the time of diagnosis was 12.3 ± 2.90 years and female/male ratio was 5.7/1. The complaint at the time of hospital presentation was goiter in 57.8% of the patients. At baseline, 36.7% of the patients were euthyroid, whereas 32.7% had subclinical hypothyroidism, 16.6 % of subjects were evaluated as hypothyroid. Twelve of the 28 patients who were initially euthyroid and not receiving therapy developed subclinical or overt hypothyroidism during the first 18 months of the follow-up period and were started on thyroid medication. At presentation, the mean anti-thyroglobulin (anti-Tg) and anti-thyroperoxidase antibody levels were 450 ± 725 IU/mL and 392 ± 428 IU/mL, respectively and at the end of the follow-up period, a significant decrease was observed in the anti-Tg levels of patients receiving levothyroxine from the beginning. CONCLUSIONS Thyroid functions of the patients with HT should be monitored periodically for hypothyroidism. Levothyroxine therapy may positively affect the clinical course of the disease and the antibody titers.

Abstract
AIMS Type 1 diabetes and autoimmune thyroiditis are common autoimmune diseases characterized by the presence of autoantibodies against tissue-specific components. Non-thyroid-specific autoantibodies are frequent in patients with autoimmune thyroiditis. The prevalence of Type 1 diabetes autoantibodies in patients with autoimmune thyroiditis is unknown. METHODS The prevalence of Type 1 diabetes autoantibodies (GAD and IA2) was analysed in 236 Sardinian children and adolescents with autoimmune thyroiditis. GAD and IA2 antibodies were measured at the time of the diagnosis of autoimmune thyroiditis and re-evaluated after 1 year in the children who were shown to be positive. Autoantibody prevalence was evaluated in 949 healthy age-matched controls. RESULTS The prevalence of GAD and/or IA2 antibodies was 8% in the children and adolescents with autoimmune thyroiditis and 4.1% in control subjects (P = 0.017). When Type 1 diabetes autoantibodies were separately analysed, the difference remained significant for IA2 (3.39% in autoimmune thyroiditis vs. 1.16% in control subjects, P = 0.012), but not for GAD (5.1% in autoimmune thyroiditis vs. 3.79% in control subjects, P = 0.367). Seven of 10 children with autoimmune thyroiditis and detectable Type 1 diabetes autoantibodies at the diagnosis remained positive after 1 year. In the course of 2 years of follow-up, two patients who were positive for Type 1 diabetes autoantibodies at the time of diagnosis of autoimmune thyroiditis developed diabetes. CONCLUSIONS This is the first study reporting the prevalence of Type 1 diabetes autoantibodies in a selected cohort of genetically homogeneous children and adolescents with autoimmune thyroiditis. The main finding was that the prevalence of Type 1 diabetes autoantibodies and of newly diagnosed Type 1 diabetes in patients with autoimmune thyroiditis was significantly higher than that observed in the general paediatric population, suggesting that children with autoimmune thyroiditis are at increased risk of developing Type 1 diabetes.

Abstract
Thyroid disease is a common paediatric disorder that affects up to 3.7% of school-aged children, and it usually presents with a goitre. By far, the most frequent cause of a goitre is autoimmune thyroid disease, although a benign colloid goitre is also a common cause. The present review focuses on the diagnostic approach to a child with a hypothyroid, hyperthyroid or euthyroid goitre.

Abstract
OBJECTIVE Chronic autoimmune thyroiditis (CAT) is the most common form of thyroiditis in childhood and a frequent cause of acquired hypothyroidism. The objective of this study was to evaluate the thyroid status of children and adolescents with CAT with respect to iodine status and diagnostic values of thyrotropin-releasing hormone (TRH) test. METHODS Seventy-one children (mean age: 11.6 years) were studied in a retrospective analysis. Free thyroxine (T4), thyrotropin (TSH), TSH response to TRH test, thyroid autoantibodies, thyroid sonography, and urinary iodine excretion (UIE) were evaluated. RESULTS At diagnosis, 8.5% of patients had overt hypothyroidisim and 36.6% subclinical hypothyroidism; 5.6% had overt hyperthyroidisim and 8.5% had subclinical hyperthyroidism. Of them, 40.8% were euthyroid. Median UIE was 51 mg/L in overt hypothyroidism and 84 mg/L in subclinical hypothyroidism. The values were 316 mg/L and 221 mg/L in overt and subclinical hyperthyroidism, respectively. Basal TSH showed a strong correlation with peak TSH level on TRH test. Thirty-four percent of patients with normal basal TSH level showed an exaggerated TSH response. CONCLUSION Iodine deficiency was seen more in cases with hypothyroidism, while excess of iodine was observed to be more frequent in hyperthyroid patients. Iodine status was a strong predictorof the thyroid status in CAT. TRH test may be helpful in further delineating patients with subclinical hypothyroidism.

Abstract
The aim of this study was to determine the frequency of thyroid autoimmunity in second grade primary school students and to examine the relationship between iodine and Hashimoto thyroiditis (HT). This was a cohort study performed with 1000 students. Urinary iodine levels, antithyroid peroxidase (anti-TPO) and antithyroglobulin (anti-Tg) antibodies were determined in all children. Children with anti-TPO or anti-Tg antibody positivity or with goiter were summoned for detailed examinations. In total, 36 cases (3.6%) were diagnosed as HT. The goiter frequency was found in 17.5% of the whole cohort. Additionally, iodine deficiency was found in 64.2% of all children. The median urinary iodine excretion was determined as 132 microg/L (range 382 microg/L) in the HT group, whereas it was 73 microg/L (range 390 microg/L) in children with goiter but without HT and 81 microg/L (range 394 microg/L) in normal children. The urinary iodine level of HT cases was significantly higher than the other two groups (p < 0.001). HT was also determined in 2% of patients with low urinary iodine levels, in 6.2% of patients with normal urinary iodine levels, and in 7.5% of patients with high urinary iodine levels. Our data demonstrates the close relationship between excessive iodine levels and autoimmunity.

Abstract
BACKGROUND In recent years, there has been an increasing attention to thyroid function in paediatric obese patients. In the present study we aimed 1) to determine the prevalence of abnormally elevated thyroid-stimulating hormone (TSH) levels in Italian obese children and adolescents 2) to investigate whether hyperthyrotropinemia in obese children cardiovascular and metabolic risk factors 3) to verify if TSH elevation is reversible after weight loss. METHODS We examined 938 obese children and adolescents (450 females). Anthropometric, metabolic and hormonal variables were determined at baseline and, in a subgroup of children with hyperthyrotropinemia, after a six month weight loss program. RESULTS Hyperthyrotropinemia (TSH >/=4.2 muUI/ml) was diagnosed in 120 patients (12,8%). Body mass index (BMI) z-score (p = 0.02) and free T3 (fT3) levels (p = 0.03) were higher in patients with elevated TSH compared to the group with normal TSH. There were not significant differences in other metabolic parameters between the two groups.A positive correlation between baseline TSH and BMI z-score (p = 0.0045) and between Ft3 and BMI z-score (p = 0.0034) was observed, while there was no correlation between TSH and lipids. Twenty-three patients among those with hyperthyrotropinemia who participated to weight reduction intervention (64 patients), presented substantial weight loss and concomitantly a significant decrease in TSH and in fT3. CONCLUSIONS These results suggest that: (1) a moderate elevation of TSH concentrations, is frequently found in obese children; (2) in obese children increase of TSH is not associated to metabolic risk factors, (3) hyperthyrotropinemia is reversible after weight loss and these data suggest that it should not be treated.

Abstract
CONTEXT TSH receptor (TSHR) blocking antibodies (Abs) inhibit TSH-induced thyroid growth and function in some adults with chronic lymphocytic thyroiditis (CLT), but their role in the pediatric age range is unknown. OBJECTIVES Our objectives were: 1) to determine the prevalence of TSHR blocking Abs in children and adolescents with CLT and 2) assess their functional significance both in vivo and in vitro. DESIGN AND SETTING This was a retrospective study in a referral outpatient setting. PATIENTS Sera from a total of 87 CLT patients and 33 controls were studied. MAIN OUTCOME MEASURES TSHR Abs were measured by both ELISA and bioassay. RESULTS Eight of 87 children and adolescents with CLT (9.2%), including one as young as 4 yr of age, had TSHR Abs in serum as measured by ELISA. The prevalence was significantly higher in individuals whose serum TSH concentration was 20 mU/liter or greater within 3 months of study than in less hypothyroid patients (eight of 45 vs. none of 42, P < 0.005). Conversely, TSHR Ab-positive patients were significantly more hypothyroid at diagnosis but only when the analysis was restricted to those with severe hypothyroidism was a decreased prevalence of goiter observed. IgG purified from TSHR Ab sera retained the TSH binding-inhibitory activity and TSHR Ab-positive sera inhibited TSH-induced stimulation of cAMP significantly more than normal. CONCLUSIONS TSHR-blocking Abs contribute significantly to the severity of the hypothyroidism in some children with CLT, but as compared with adults, they appear to play less of a role in determining the presence or absence of a goiter.

Abstract
CONTEXT The prognosis of Hashimoto's thyroiditis (HT) in children and adolescents is not well known and studies reporting long-term outcome of the disease are scarce. OBJECTIVE To assess the thyroid hormone status during long-term follow-up and to establish the prognosis of children and adolescents with HT. PATIENTS One hundred and twenty-nine patients with HT were re-evaluated for thyroid hormone status after a mean follow-up period of 50 months. RESULTS Seventy-seven per cent of the euthyroid patients were still euthyroid, while 21.1% of these patients became hypothyroid at the time of re-evaluation. However, 69.5% of hypothyroid patients remained hypothyroid (overt or subclinical) and 30.5% recovered. CONCLUSION HT is a dynamic process. Thyroid functions can show variation during follow-up. Therefore, thyroid function tests should be repeated periodically to detect progression to hypothyroidism in initially euthyroid patients as well as reversibility of hypothyroidism.

Abstract
CONTEXT Because clinical manifestations of thyroid disorders are variable and subtle in children and adolescents, thyroid function tests are often repeated in patients with nonspecific symptoms. OBJECTIVES The objective of the study was to determine the natural history of initial abnormal TSH and define populations at greater risk for developing a subsequent thyroid dysfunction. METHODS A total of 121,052 of 1.043 million outpatients aged 0.5-16 yr insured by the Clalit Health Medical Organization had a TSH determination in 2002 and follow-up to 2007. Extracted from the Clalit Health Medical Organization database were their demographic data, referral diagnoses, and laboratory results (TSH, free T(4), thyroid antibodies). Excluded were patients with overt hypothyroidism or hyperthyroidism on initial testing. RESULTS Results of 96.5% of initial serum TSH concentrations were normal (0.35-5.5 mIU/liter), 0.2% were low (<0.35 mIU/liter), 2.9% elevated (>5.5 to <or=10 mIU/liter), and 0.4% highly elevated (>10 mIU/liter). The frequency of TSH testing increased with age and female gender. During follow-up, repeated (two to more than four) TSH tests were performed in 45.7% of the patients. In the second TSH determination, normal TSH was documented in 40, 73.6, and 78.9% of those whose initial serum TSH was highly elevated, elevated, and low, respectively, and in 97% of those with normal initial TSH. Predictive factors for a sustained highly elevated TSH were initial TSH greater than 7.5 mIU/liter (P = 0.014) and female gender (P = 0.047). CONCLUSIONS In the pediatric population, initial normal or slightly elevated TSH levels are likely to remain normal or spontaneously normalize without treatment. Patients with initial levels greater than 7.5 mIU/liter, particularly girls, are at a greater risk for sustained abnormal TSH levels.

Abstract
BACKGROUND Few studies have addressed the clinical evolution of autoimmune thyroiditis (AIT) occurring in childhood and scant data are available on the role of thyroid ultrasonography. We aimed to evaluate the natural history of AIT diagnosed in children and adolescents and to assess the possible prognostic role of ultrasonography. METHODS Retrospective case series prospectively followed up for a further 3-year period. RESULTS A series of 23 patients with AIT, diagnosed before 18 years of age from 1994 to 2004, was further followed up from 2005 to 2007 with clinical, laboratory, and ultrasound evaluation. Hypothyroid patients were treated with levothyroxine (LT(4)), while euthyroid patients were left untreated. Patients with subclinical hypothyroidism were also evaluated 40 days after LT(4) withdrawal. At diagnosis seven patients were euthyroid, 14 with subclinical hypothyroidism, and two with overt hypothyroidism. Median follow-up was 4.7 years. At last follow-up visit, none of the seven euthyroid patients had developed hypothyroidism. Three of the 14 patients with subclinical hypothyroidism recovered a normal thyroid function while only one patient showed an increase in TSH level. By serological screening we identified three patients with other autoimmune disorders. CONCLUSIONS In young patients with normal or mildly increased TSH levels and minimal echographic changes, AIT may remain stationary for years. In fact, patients with subclinical hypothyroidism recover a normal thyroid function in approximately 20% of cases. In patients with subclinical hypothyroidism and goiter, LT(4) therapy may induce thyroid size reduction. Screening for other autoimmune disorders is useful to identify patients that need further diagnostic assessment.

Abstract
Although autoimmune thyroid disease (AITD) is frequent in Turner's syndrome (TS), followup studies are scant, and there are none regarding subclinical thyroiditis. We investigated thyroid function and morphology in 17 patients with TS (mean age 14.6 years) with transient and asymptomatic variations of TSH and/or thyroid hormones. Our 2-year follow-up included measurements of TSH, free T4, T3 and TPO and Tg antibodies, ultrasound (US) (first and last evaluations) and scintigraphy (first evaluation). Thyroid volume was evaluated relative to the patients' stature. Fourteen had abnormal hormones, including four with hypothyroidism and one with hyperthyroidism, ten had positive antibodies, and all had abnormalities on US; uptake was normal in 14/16. Abnormal hormones were independent of antibodies, number of US findings, age, time of disease and volume. At the end of the follow-up, antibodies were associated with a high number of abnormal US features, particularly heterogeneous texture. Our results indicate that recurring thyroid hormone variations in TS are due to chronic AITD.

Abstract
BACKGROUND High surgeon volume is associated with improved outcomes in adult endocrine surgery. This is the first population-based outcomes study for thyroidectomy/parathyroidectomy in children. METHODS Cross-sectional analyses were performed using 1999 to 2005 Healthcare Cost and Utilization Project Nationwide Inpatient Sample data. Outcomes included complications, length of stay (LOS), and costs. High-volume surgeons performed >30 cervical endocrine procedures per year in adults and children; pediatric surgeons restricted >90% of their practices to patients </=17 years old. Other surgeons fell into neither category. Bivariate and multivariate regression analyses were performed. RESULTS We included 607 patients, representing 20% of the pediatric endocrine operations done between 1999 and 2005 in the United States. Seventy-six percent of patients were female. Among the procedures performed, 92% were thyroidectomies and 8% were parathyroidectomies. Surgeons were classified as follows: 18% High-volume, 21% Pediatric, and 61% Other. High-volume surgeons had the lowest LOS (1.5 days vs 2.3 Pediatric, 2.0 Other; P = .01), costs ($12,474 vs $19,594 Pediatric, $13,614 Other; P < .01), and complications (6% vs 11% Pediatric, 10% Other; P = NS). In multivariate analyses, case volume of the endocrine surgeons was an independent predictor of LOS and costs. CONCLUSION High-volume surgeons have better outcomes after thyroidectomy/parathyroidectomy in children compared with Pediatric and Other surgeons. Surgeon experience was an independent predictor of LOS and costs. High-volume endocrine and pediatric surgeons could combine expertise to improve outcomes in children.

Abstract
OBJECTIVE Alterations in thyroid function are reported in obesity, although no relevant data exist on the thyroid structure of these patients and the frequency of autoimmunity. The aim of our study was to evaluate the involvement of the thyroid gland in a large group of obese children. DESIGN This was a cross-sectional study. METHODS The study was conducted between March 2004 and December 2007 in 186 overweight and obese children. In all subjects, serum free T(3), free T(4), TSH, antithyroid antibodies, and a thyroid ultrasound were assessed. A total ot 40 healthy children matched for age and of normal weight for height served as controls. RESULTS A total of 23 children (12.4%) showed antithyroid antibodies and an ultrasound pattern suggestive of Hashimoto's thyroiditis (group A). Of them, 20 (10.8%) showed antithyroid antibodies and normal ultrasound (group B). A total of 70 subjects (37.6%) showed absent antithyroid antibodies and an ultrasound pattern suggestive of Hashimoto's thyroiditis (group C), and 73 children (39.2%) showed no thyroid antibodies with normal ultrasound (group D). TSH was higher in groups A and C compared with groups B and C, and controls (P < 0.05). Mean free T(4) was lower in group B (P < 0.05) than in controls, whereas free T(3) was higher in group C than in controls (P < 0.05). TSH and body mass index sd scores were significantly correlated in group C (P < 0.001), and TSH was also significantly associated with the degree of thyroid structure alterations (P < 0.05). CONCLUSION Obese children frequently show alterations of thyroid structure and function that are not completely explained by the presence of an autoimmune involvement.

Abstract
BACKGROUND Patients with autoimmune thyroiditis can present with thyroid function that varies from euthyroidism to frank hypothyroidism or occasionally hyperthyroidism. Although there is a risk of progression from the euthyroid or subclinical hypothyroid state to frank hypothyroidism, the rate of progression is not known. OBJECTIVES Subjects with diffuse goiter and autoimmune thyroiditis were followed up to observe the rate of deterioration in thyroid function from euthyroid and subclinical hypothyroid states to hypothyroidism. METHODS Patients who presented with goiter and autoimmune thyroiditis were grouped as those with euthyroidism, subclinical hypothyroidism, and overt hypothyroidism on the basis of levels of thyroxine and thyrotropin at presentation. Patients were followed up for a minimum duration of 24 months with periodic monitoring of thyroid function. RESULTS Ninety-eight consecutive subjects (aged of 8-18 years) with a diagnosis of autoimmune thyroiditis and diffuse goiter were studied. At presentation, in 24 subjects (24.5%) thyroid function was normal (euthyroidism), 32 (32.6%) had subclinical hypothyroidism, and the remaining 42 subjects (42.9%) had hypothyroidism. All of the subjects with hypothyroid were maintained euthyroid on thyroxine during follow-up. Hypothyroidism developed in 3 of 24 patients with euthyroidism and in 4 of 32 patients with subclinical hypothyroidism. CONCLUSIONS Subjects with goitrous autoimmune thyroiditis need periodic monitoring of thyroid function. Development of thyroid dysfunction is insidious and may not be accompanied by symptoms and clinical signs. In pediatric and adolescent age groups it is imperative to correct thyroid dysfunction to achieve optimal growth and development.

Abstract
AIM To determine clinical and laboratory differences at presentation of autoimmune thyroiditis (AIT) among children with AIT discovered due to symptom development and those discovered by screening due to having increased risk of AIT from an underlying disorder. STUDY DESIGN Retrospective chart review of patients with AIT seen in an academic pediatric endocrinology practice. We identified 252 children with AIT: 160 diagnosed following symptom development (the 'symptoms' group), 74 with AIT found by screening (the 'screening' group) and 18 with increased risk who were tested because they developed symptoms (the 'symptoms + screening' group). RESULTS We found that compared to the 'symptoms' group, individuals in the 'screening' group were younger and had a lower proportion of females. In addition, the 'screening' group were more likely to be euthyroid (60% of 'screening' vs 19% for 'symptoms') and less likely to have overt hypothyroidism (7% 'screening' vs 45% 'symptoms'). The 'screening' group were also less likely to have multiple symptoms of hypothyroidism noted in retrospect. CONCLUSIONS Screening for AIT identifies patients at an earlier stage of AIT. Additionally, the association of symptoms with subclinical hypothyroidism may lend support to initiating levothyroxine treatment for symptomatic children with mild TSH elevations.

Abstract
Autoimmune thyroiditis is a frequent cause of goiter in children and studies point to the increasing prevalence of juvenile autoimmune thyroiditis (JAT) in children and adolescents. Clinically, JAT can manifest, depending on the presence or absence of goiter, as either a goitrous form or atrophic form. Both are characterized by the presence of thyroid antibodies in serum, with the goitrous form being more common in children. Recent evidence suggests that thyroid autoimmunity originates from an interaction of genetic, endogenous and environmental factors which end up activating thyroid-specific autoreactive T-cells in susceptible children. In addition to underlying genetic/HLA predisposition, factors including sex hormones, glucocorticoids, low birth weight, radiation and drugs may play a role in thyroid autoimmunity. Patients with JAT can present due to thyroid enlargement or symptoms arising due to hypothyroidism. Asymptomatic enlargement of the thyroid gland is a common presenting complaint, especially in older children and adolescents. Thyroid function can vary from euthyroidism to subclinical or overt forms of hypothyroidism and less commonly hyperthyroidism. Accordingly, patients can be symptomatic. There is considerable debate regarding the management of patients with euthyroidism or subclinical hypothyroidism. Available evidence indicates the presence of residual goiter in endemic form and a high prevalence of JAT in children. It is suggested that children should be screened for goiter as part of school health examinations, and goitrous children should be monitored for thyroid function.

Abstract
OBJECTIVE To study the natural history of Hashimoto's thyroiditis (HT) in children and identify factors predictive of thyroid dysfunction. STUDY DESIGN We evaluated 160 children (43 males and 117 females, mean age 9.10 +/- 3.6 years, with HT and normal (group 0; 105 patients) or slightly elevated (group 1; 55 patients) serum thyroid-stimulating hormone (TSH) concentrations. The patients were assessed at presentation and then followed for at least 5 years if they remained euthyroid or if their TSH did not rise twofold over the upper normal limit. RESULTS At baseline, age, sex, thyroid volume, free thyroxine, free triiodothyronine, thyroid peroxidase antibody (TPOab), and thyroglobulin antibody (TGab) serum concentrations were similar in the 2 groups. During follow-up, 68 patients of group 0 remained euthyroid, and 10 patients moved from group 0 to group 1. In 27 patients, TSH rose twofold above the upper normal limit (group 2), and 9 of these patients developed overt hypothyroidism. Sixteen patients of group 1 ended up in group 0, 16 remained in group 1, and 23 moved to group 2. A comparison of the data of the patients who maintained or improved their thyroid status with those of the patients whose thyroid function deteriorated revealed significantly increased TGab levels and thyroid volume at presentation in the latter group. However, none of these parameters alone or in combination were of any help in predicting the course of the disease in a single patient. CONCLUSIONS The presence of goiter and elevated TGab at presentation, together with progressive increase in both TPOab and TSH, may be predictive factors for the future development of hypothyroidism. At 5 years of follow-up, more than 50% of the patients remained or became euthyroid.
