An update on thyroid-associated ophthalmopathy in children and adolescents

Efficacy of Tocilizumab in Refractory Graves Orbitopathy From Real-World Clinical Practice: An Observational Study

Context

The efficacy of tocilizumab (TCZ) in treating Graves orbitopathy (GO) remains uncertain due to the small sample sizes of earlier studies, and there is a lack of research on the drug for juvenile GO.

Objective

To evaluate the effectiveness of TCZ in treating GO that is resistant to conventional therapy.

Design

This observational study at a tertiary care center included 79 Chinese GO patients, 15 of whom were pediatric patients, with 52 of these patients having moderate to severe active GO (all adult patients having steroid-resistant GO). Intravenous infusion of TCZ 8 mg/kg was given every 28 days for 4 months. Changes from baseline in visual acuity (VA), intraocular pressure (IOP), proptosis, clinical activity score (CAS), and thyrotropin receptor antibody (TRAb) levels throughout TCZ therapy were assessed at baseline (T0), the fifth month (T4), and follow-up (T5). Additionally, improvements in CAS by at least 2 points and CAS < 4 points at T4 and T5 were evaluated.

Results

Significant improvements were found in VA, IOP, proptosis, CAS, and TRAb levels in the adult group, and proptosis in the pediatric group at T5 (P < .05). Additionally, significant improvements were identified in TRAb levels and CAS (active GO at T0) in the pediatric group at T4 (P < .05). In the adult and pediatric group with active GO at T5, 71.4% and 60% experienced a decrease in CAS by ≥ 2 points, respectively; 89.3% and 60% achieved the response criterion of low activity disease (CAS < 4 points), respectively.

Conclusion

TCZ emerged as a valuable therapeutic option for Chinese patients with active, corticosteroid-resistant, moderate to severe GO.

Age and gender influence on clinical manifestations of thyroid-associated ophthalmopathy: a case series of 2479 Chinese patients

Background

Significant individual differences exist in the clinical manifestations of thyroid-associated ophthalmopathy (TAO). Age and gender have an impact on the presentation and severity of TAO.

Objective

To evaluate the clinical characteristics of TAO patients, with particular consideration of their age and gender.

Methods

Demographic and clinical data of 2479 TAO patients were collected. Patients were divided into 7 groups based on age: Group 1: ≤18 years old; Group 2: 19-29 years old; Group 3: 30-39 years old; Group 4: 40-49 years old; Group 5: 50-59 years old; Group 6: 60-69 years old; Group 7: ≥70 years old. Compared clinical manifestations among different groups and between males and females.

Result

In age group 1, the ratio of female to male TAO patients was 3.79, and in age group 7, it was 0.86. As age increased, there was a decline in the percentage of females (γ=-0.168, p<0.001). During the aging process, the proportion of TAO patients with unilateral involvement also gradually decreased (γ=-0.23, p<0.001). In addition, the proportion of TAO patients with upper eyelid retraction ≥2mm and exophthalmometry ≥17mm also decreased (γ=-0.158, p<0.001, γ=-0.23, p<0.001). In comparison to males, females with TAO showed a higher proportion of unilateral eye involvement and upper eyelid retraction ≥2mm (p=0.038, p<0.001). However, males had a higher proportion of exophthalmometry ≥17mm (p<0.001). The proportions of patients with eye movement disorder (γ=0.535, p<0.001), diplopia (γ=0.446, p<0.001), intraocular pressure (IOP) ≥30mmHg (γ=0.149, p<0.001), sight-threatening TAO (γ=0.479, p<0.001), and active TAO (γ=0.469, p<0.001) were positively correlated with age in TAO patients. Additionally, the proportion of male patients is higher than that of female patients.

Conclusion

TAO Patients exhibit different clinical features depending on age and gender. In elderly and male patients, TAO tends to be more severe, with a higher prevalence of eye muscle involvement, IOP ≥30mmHg, active phases, and a lower proportion of patients with upper eyelid retraction ≥2mm. Elderly female patients also have a lower proportion of exophthalmometry ≥17mm.

Are Mental Health Problems and Mindfulness Awareness Related to Levothyroxine Replacement in Adolescent Patients With Hashimoto's Thyroiditis?

Considering the possible adverse effects of thyroid autoantibodies on the brain, the present study aimed to investigate whether there was a difference in mental health difficulties and mindfulness awareness levels between subclinical Hashimoto's thyroiditis patients with and without levothyroxine (LT4) use. A case-control study was conducted. The Strengths and Difficulties Questionnaire (SDQ) and the Mindful Attention Awareness Scale (MAAS) were used to screen mental health difficulties and mindfulness awareness. Scale scores were compared by performing correlation analysis between the groups with respect to LT4 use and thyroid autoantibodies. Levothyroxine alone does not affect scale results. Higher thyroid peroxidase antibody (TPOAb) titers were positively correlated with the behavioral problems subscale of the SDQ, while awareness level in patients was inversely correlated with higher thyroglobulin antibody (TgAb) levels.

Optical coherence tomography angiography findings in pediatric patients with graves ophthalmopathy

PURPOSE

The aim of this study was to evaluate peripapillary, macular microvascular structure, and retinal nerve fiber layer (RNFL) thickness profile in children with Graves Ophthalmopathy (GO).

MATERIAL AND METHODS

Thirty-six eyes of 18 children with GO were prospectively compared with 40 eyes of 20-age and sex-matched controls. The severity and activity of the disease were evaluated according to the criteria of the European Group on Graves' Ophthalmopathy (EUGOGO) and Clinical Activity Score (CAS). After complete ophthalmologic and endocrinologic examination, all patients underwent optical coherence tomography (OCT) and optical coherence tomography angiography (OCTA) measurements. Retinal nerve fiber layer (RNFL) thickness, macular superficial capillary plexus (SCP), deep capillary plexus (DCP), foveal avascular zone (FAZ) area, acircularity index (AI) of the FAZ and peripapillary microvascular structure were analyzed.

RESULTS

The mean age was 12.1 ± 2.4 years in the GO group and 11.2 ± 2.6 years in healthy control group (p = 0.11). Duration of disease was 8.9 ± 4.2 months in the GO group. All patients in GO group had mild and inactive ophthalmopathy. In temporal inferior quadrant, RNFL thickness was significantly thinner in the GO group compared to the control group (p = 0.03). No significant difference was seen between groups both peripapillary and macular microvascular structure (all p > 0.05).

CONCLUSION

GO has no effect on optic nerve thickness, peripapillary and macular vascular parameters except inferior temporal RNFL in children.

Longitudinal follow-up of pediatric Graves' disease in preschool children: Clinical characteristics and a case report

RATIONALE

Pediatric Graves' disease at preschool age is a rare condition. Previous reports have indicated that adolescents with this disease are girls. Pediatric Graves' ophthalmopathy in young children is rare, and long-term follow-up reports are lacking.

PATIENT CONCERNS

The patient had hyperthyroidism and bilateral proptosis for 2 years, but she was only 4 years old.

DIAGNOSES

The blood test revealed hyperthyroidism and the ophthalmic examination revealed proptosis. The patient had Graves' disease and Graves' ophthalmopathy.

INTERVENTIONS

Initially, she was followed up in the pediatric department. Bilateral proptosis developed, and she was brought to the ophthalmology department for assistance. Orbital computed tomography revealed borderline enlargement of the extraocular muscles bilaterally. Other initial clinical findings included bilateral upper and lower eyelid trichiasis and mild punctate epithelial erosions of the cornea. She received conservative medical treatment in the ophthalmology department.

OUTCOMES

Remission of hyperthyroidism was achieved 2 years after medical control. No elevated intraocular pressure, strabismus, or optic neuropathy developed during follow-up. Significant cosmetic improvement and gradual resolution of punctate epithelial erosions were found over 10 years. Finally, the patient had only mild bilateral lower trichiasis.

LESSONS

Longitudinal follow-up revealed that the ocular manifestations of proptosis and eyelid trichiasis may have good outcomes. Proptosis gradually improved as the patient grew up.

Detection and Correlation Analysis of Serum Uric Acid in Patients with Thyroid-Associated Ophthalmopathy

Purpose

To probe the property of serum uric acid in evaluating the activity of patients with thyroid-associated ophthalmopathy.

Methods

A total of 443 patients with TAO admitted to our hospital from March 2016 to February 2021 were selected for the observation group. Simultaneously, 443 healthy subjects were selected for the control group. The observation group was divided into the active group (n = 254) and the inactive group (n = 189) according to the clinical activity score (CAS). Besides, the patients were divided into mild group (n = 201), moderate severe group (n = 133) and extremely severe group (n = 109) based on the severity of TAO. Serum uric acid, free triiodothyronine (FT3), free thyroid hormone (FT4), thyrotropin stimulating hormone (TSH) and glycosylated hemoglobin (HbA1c) levels were detected and analyzed in each group.

Results

Serum UA, FT3, FT4, TSH and HbA1c in the active group were significantly enhanced than those in the other two groups (P < 0.05), and there was no significant difference between the inactive group and the control group (P > 0.05). In different disease severity groups, the serum UA level of patients in the active group was significantly promoted than that in the inactive group and control group (P < 0.05) and was decreased successively in extremely severe group, moderate severe group and mild group, with statistical significance (P < 0.05). Pearson's analysis showed that UA was positively correlated with FT3, FT4, and HbA1c (r = 0.652, P = 0.031; r = 0.571, P = 0.042; r = 0.737, P = 0.024), while was reversely correlated with TSH level (r = -0.137, P = 0.262). There was no correlation between UA and FT3, FT4, and HbA1c levels in the inactive group. UA detection showed the average sensitivity and specificity of TAO activity were 94.3% and 85.2%, respectively. There was no significant correlation between the severity of disease and serum UA in inactive patients (P = 0.135). There was a positive correlation between the severity of disease and serum UA in active patients (P = 0.005).

Conclusion

UA may be used as a laboratory indicator for quantitative clinical diagnosis of thyroid-associated ophthalmopathy (TAO) and as a parameter for the presence of TAO activity.

Pediatric Graves' orbitopathy: a multicentre study

PURPOSE

Graves' orbitopathy (GO) is a rare condition in children often considered to be a less severe condition than at an older age. The aim of our study was to analyse if there are any factors that distinguish paediatric from adult GO in order to provide guidelines for assessing and managing paediatric GO.

METHODS

Study design is a multicentre retrospective observational case series; 115 paediatric patients diagnosed with GO who visited our university medical centres in the Netherlands and Iran between 2003 and 2019 were submitted for complete ophthalmological examinations, serological testing and/or orbital imaging. Main outcome measures focussed on the natural course and clinical picture as well as medical and surgical treatment in paediatric GO.

RESULTS

Clinical findings included proptosis (n = 97; 84.3%), eyelid retraction (n = 77; 67%) and diplopia (n = 13; 11.3%). Ninety-two patients (80%) presented with mild disease, 21 (18.3%) with moderate-severe disease and two (1.7%) with severe GO. Five patients (4.3%) underwent intravenous glucocorticoids and 25 patients underwent orbital decompression surgery. Strabismus surgery due to primary involvement of extraocular muscles was performed in two patients (1.7%). Overall, rehabilitative surgical treatment was planned in 31 patients (26.9%) with inactive disease. Two patients experienced reactivation of the disease.

CONCLUSION

Despite the fact that paediatric and adult GO are considered two separate entities, they might be the same disease with two different clinical phenotypes. Paediatric GO population presents with a comparable clinical picture regarding both soft tissue involvement and proptosis, which may require surgical intervention. Proptosis was present in the majority of paediatric GO patients. Orbital decompression was performed in 21.7% of patients.

Eye symptoms in patients with benign thyroid diseases

Thyroid diseases may cause a variety of functional and structural body changes, including eye and vision abnormalities, which can have a negative impact on a patient’s well-being. However, only a few studies on the impact of other benign thyroid diseases on the visual process are available in the literature. In this study, using the Polish version of the thyroid-specific quality of life (ThyPROpl) questionnaire, we aimed to determine the self-reported influence of benign thyroid diseases (e.g., nodular goiter, toxic nodular goiter, Graves’ disease, thyroid orbitopathy, Hashimoto’s thyroiditis, and surgical hypothyroidism) on patients’ eyes and vision. This was a prospective study. In total, 374 randomly selected euthyroid patients and 255 control subjects responded to the ThyPROpl questionnaire and the results were evaluated. Nearly 69% of the respondents reported that the most frequent condition was “reduced sight.” Men most often reported wet/tearing eyes (66%). The occurrence of eyelid sacks or swollen eyelids (64%), ophthalmalgia (62%), and eye dryness (61%) was marked almost as often. In total, 29% of the patients reported diplopia, and it was found to be most prevalent among those with thyroid orbitopathy. Other complaints were similarly prevalent among all the subgroups. A positive correlation was also observed between the scores of the “eye symptoms” and other ailments. Except for swelling around the lower eyelids, patients with thyroid diseases more frequently experienced all of the ocular complaints analyzed in this study compared with controls. This study showed that eye complaints are common in patients with benign thyroid diseases and ocular disturbances have a negative impact on the overall quality of life of patients.

Thyroid-related ophthalmopathy development in concurrence with growth hormone administration

BACKGROUND

Thyroid stimulating hormone (TSH) receptor and local infiltrate lymphocytes have been considered as major pathological factors for developing thyroid-related ophthalmopathy. Overexpression of insulin-like growth factor-I (IGF-I) receptor has emerged as a promising therapeutic target for refractory patients. However, the relationship between activation of growth hormone (GH)/IGF-I receptor signaling and development or exacerbation of thyroid ophthalmopathy has not been elucidated. Herein we describe a case that provides further clarification into the association between thyroid-related ophthalmopathy and GH/IGF-I receptor signaling.

CASE PRESENTATION

A 62-year-old Japanese female diagnosed with thyroid-related ophthalmopathy was admitted to Kurume University Hospital. She had received daily administration of GH subcutaneously for severe GH deficiency; however, serum IGF-I levels were greater than + 2 standard deviation based on her age and sex. She exhibited mild thyrotoxicosis and elevation in levels of TSH-stimulating antibody. Discontinuation of GH administration attenuated the clinical activity scores of her thyroid-related ophthalmopathy. Additionally, concomitant use of glucocorticoid and radiation therapies resulted in further improvement of thyroid-related ophthalmopathy. The glucocorticoid administration was reduced sequentially, followed by successful termination. Thereafter, the patient did not undergo recurrence of thyroid-related ophthalmopathy and maintained serum IGF-I levels within normal physiological levels.

CONCLUSIONS

We describe here a case in which development of thyroid-related ophthalmopathy occurred upon initiation of GH administration. GH/IGF-I signaling was highlighted as a risk factor of developing thyroid-related ophthalmopathy. Additionally, aberrant TSH receptor expression was suggested to be a primary pathophysiological mechanism within the development of thyroid-related ophthalmopathy. Physicians should be aware of the risks incurred via GH administration, especially for patients of advanced age, for induction of thyroid-related ophthalmopathy.

Ocular Complications of Obstructive Sleep Apnea

Obstructive sleep apnea (OSA), the most common form of sleep-disordered breathing, is characterized by repetitive episodes of paused breathing during sleep, which in turn induces transient nocturnal hypoxia and hypercapnia. The high prevalence of OSA and its associated health consequences place a heavy burden on the healthcare system. In particular, the consequent episodic oxygenic desaturation/reoxygenation series and arousals from sleep in patients with OSA have the potential to trigger oxidative stress, elevated systemic inflammatory responses, and autonomic dysfunction with sympathetic activation. Given these adverse side-effects, OSA is highly correlated to many eye diseases that are common in everyday ophthalmic practices. Some of these ocular consequences are reversible, but they may permanently threaten a patient’s vision if not treated appropriately. Here, this article seeks to review the ocular consequences and potential pathophysiologic associations in patients with OSA. Understanding these OSA-related eye diseases may help clinicians provide comprehensive care to their patients.

Prevalence of hyperthyroidism, hypothyroidism, and euthyroidism in thyroid eye disease: a systematic review of the literature

BACKGROUND

Thyroid eye disease is an autoimmune disorder of the orbital retrobulbar tissue commonly associated with dysthyroid status. The most frequent condition is hyperthyroidism, although it is also present in hypothyroid and euthyroid patients. The prevalence of thyroid conditions in patients with thyroid eye disease had been previously evaluated; however, there is no consensus on a global prevalence. The study aims to estimate the prevalence of hyperthyroidism, hypothyroidism, and euthyroidism in patients with TED, through a systematic review of literature.

METHODS

We conducted a systematic review of the literature following the PRISMA guidelines, in MEDLINE, COCHRANE, EMBASE, Science Direct, and LILACS databases. Inclusion criteria were primary studies of patients with a diagnosis of thyroid eye disease made by an ophthalmologist or with diagnosis criteria, with measurement of thyroid function (TSH, T3, and free T4), and diagnosis of the primary thyroid condition. A quality assessment was made through the Joanna Briggs Institute Quality tools. Finally, we extracted relevant details about the design, the results, and the prevalence of thyroid disorders in thyroid eye disease.

RESULTS

The initial search revealed 916 studies, of which finally thirteen met inclusion criteria. Six studies were performed in Europe (Germany, Wales, and Spain), five in Asia (Iran, South Korea, Japan, and Singapore), one in North America (USA), and one in Africa (Ghana). The global prevalence, in patients of thyroid eye disease, was 10.36% for hypothyroidism, 7.9% for euthyroidism, and 86.2% for hyperthyroidism.

CONCLUSIONS

Professionals should be aware that thyroid eye disease can be present in patients with a normal thyroid function. The assessment for these patients is based on orbital images; serum TSH, T3, and free T4; antibody levels as thyrotropin receptor antibodies; and thyroperoxidase levels. Additionally, we want to encourage research in this field in other regions of the world such as Latin America.

Surgical management of benign thyroid disease in children

Benign thyroid disease in children represents a wide spectrum of disease. While most benign thyroid disorders may be either monitored or managed medically, surgery is an important treatment, particularly for Graves' disease or large multinodular goiters. Multidisciplinary teams including specialists in pediatric endocrinology, genetics, radiology, pathology and surgery at high volume centers offer the safest and most effective management.

Orbital pseudotumor as the presenting symptom of Crohn's disease in a male child

Purpose

This report will describe a case of orbital pseudotumor that is associated with underlying Crohn's disease in a pediatric patient.

Observations

An 8-year-old male with a past medical history of chronic constipation who presented to the ophthalmologist in July 2017 with a 7-month history double vision, left upper lid ptosis, left abducens nerve palsy, and an abnormal thyroid test. The patient's family history was negative for any autoimmune disease including, juvenile idiopathic arthritis, rheumatoid arthritis, thyroid disease, type 1 diabetes mellitus or inflammatory bowel disease. Diagnosis of orbital pseudotumor of the left eye was made based on CT scan findings and he was then treated with a one-week course of oral prednisone. After resolution of his initial symptoms, he presented a month later with swelling in his left eye and was treated with a 6-month steroid taper with resolution of symptoms. In June 2018, the patient presented with swelling in his right eye and was treated with prednisone plus steroid sparing agents. Extraocular muscle biopsy was negative for IgG4 related disease, fungal infection, or malignant lymphoma and workup for sarcoidosis and granulomatosis with polyangiitis was unremarkable. In September 2018, the patient presented with bloody stools, diagnosed and treated for a perirectal abscess. Subsequent colonoscopy performed in January 2019 confirmed Crohn's disease. He is currently undergoing treatment with adalimumab and is in remission in terms of orbital pseudotumor.

Conclusion and Importance

In conclusion, although the association between orbital pseudotumor and Crohn's disease is very rare, medical professionals should remember this connection when a patient presents with idiopathic orbital pseudotumor. To rule out this possibility, we recommend a thorough history of GI findings should be taken on the initial patient encounter. Crohn's disease may be an underlying cause of certain cases of orbital pseudotumor, and treatment and control of the underlying Crohn's disease may help to reduce recurrence rates of orbital pseudotumor. Additional studies need to be performed to better understand the association between the two diseases.

Management of Thyrotoxicosis in Children and Adolescents: A Turkish Multi-center Experience

OBJECTIVE

To determine the demographic and biochemical features of childhood and juvenile thyrotoxicosis and treatment outcome.

METHODS

We reviewed the records of children from 22 centers in Turkey who were diagnosed with thyrotoxicosis between 2007 to 2017.

RESULTS

A total of 503 children had been diagnosed with thyrotoxicosis at the centers during the study period. Of these, 375 (74.6%) had been diagnosed with Graves’ disease (GD), 75 (14.9%) with hashitoxicosis and 53 (10.5%) with other less common causes of thyrotoxicosis. The most common presenting features in children with GD or hashitoxicosis were tachycardia and/or palpitations, weight loss and excessive sweating. The cumulative remission rate was 17.6% in 370 patients with GD who had received anti-thyroid drugs (ATDs) for initial treatment. The median (range) treatment period was 22.8 (0.3-127) months. No variables predictive of achieving remission were identified. Twenty-seven received second-line treatment because of poor disease control and/or adverse events associated with ATDs. Total thyroidectomy was performed in 17 patients with no recurrence of thyrotoxicosis and all became hypothyroid. Ten patients received radioiodine and six became hypothyroid, one remained hyperthyroid and restarted ATDs and one patient achieved remission. Two patients were lost to follow up.

CONCLUSION

This study has demonstrated that using ATDs is the generally accepted first-line approach and there seems to be low remission rate with ATDs in pediatric GD patients in Turkey.

Corticosteroids in Moderate-To-Severe Graves' Ophthalmopathy: Oral or Intravenous Therapy?

Background: Ophthalmopathy is a rare extra-thyroid manifestation of Graves’ disease, in paediatrics. Intravenous corticosteroids are the main treatment of moderate-to-severe Graves’ orbitopathy. In this paper, we describe a moderate-to-severe active Graves’ ophthalmopathy in a child and the response to oral therapy with prednisone. Case presentation: A nine-year-old male child suffering for a few months, from palpitations, tremors, and paresthesia was hospitalized in our Pediatric Clinic. At admission, the thyroid function laboratory tests showed hyperthyroidism with elevated free thyroxine (FT4) and free triiodothyronine (FT3) levels and suppressed thyroid-stimulating hormone (TSH) levels. These findings, combined with the clinical conditions—an ophthalmologic evaluation (that showed the presence of exophthalmos without lagophthalmos and visual acuity deficiency), thyroid ultrasound, and TSH receptor antibody positivity—led to a diagnosis of Graves’ disease. Therefore, methimazole was administered at a dose of 0.4 mg/kg/day. After 4 months, thyroid function was clearly improved, with normal FT3 and FT4 values and increasing TSH values, without adverse effects. Nevertheless, an eye examination showed ophthalmopathy with signs of activity, an increase in the exophthalmos of the right eye with palpebral retraction, soft tissue involvement (succulent and oedematous eyelids, caruncle and conjunctival hyperaemia and oedema) and keratopathy, resulting from exposure. We began steroid therapy with oral administration of prednisone (1 mg/kg/day) for four weeks, followed by gradual tapering. After one week of therapy with prednisone, an eye assessment showed reduced retraction of the upper eyelid of the right eye, improvement of right eye exophthalmometry and reduction of conjunctival hyperaemia. After four weeks of therapy with prednisone, an eye assessment showed reduction of the right palpebral retraction without conjunctival hyperaemia and no other signs of inflammation of the anterior segment; after twelve weeks, an eye assessment showed a notable decrease in the right palpebral retraction and the absence of keratitis, despite persisting moderate conjunctival hyperaemia. No adverse event associated with steroid use was observed during the treatment period and no problem in compliance was reported. Conclusion: Prednisone seems a better choice than intravenous corticosteroids, for treating moderate-to-severe and active Graves’ ophthalmopathy, keeping in mind the importance of quality of life in pediatric patients.

Long-term outcome of thyrotoxicosis in childhood and adolescence in the west of Scotland: the case for long-term antithyroid treatment and the importance of initial counselling

BACKGROUND

Thyrotoxicosis is both rarer and more severe in children than in adults, rendering management difficult and often unsatisfactory.

OBJECTIVE

To ascertain outcome in a geographically defined area of Scotland between 1989 and 2014.

METHOD

Retrospective case note review with follow-up questionnaire to family doctors for patients with Graves' disease and Hashimoto's thyroiditis.

RESULTS

Sixty-six patients (58 females:8 males) comprising 53 with Graves' disease and 13 with Hashimoto's thyroiditis were diagnosed at median 10.4 (2.9-15.8) years and followed up for 11.8 (2.6-30.2) years. Antithyroid drug (ATD) therapy was stopped electively in 35 patients after 4.5 (1.5-8.6) years, resulting in remission in 10/13 Hashimoto's thyroiditis and 10/22 Graves' disease. Side effects occurred in 12 patients receiving carbimazole, six of whom changed to propylthiouracil; no adverse events occurred in the latter patients.Second-line therapy was given to 37 patients (34 with Graves' disease), comprising radioiodine (22) at 15.6 (9.3-24.4) years for relapse (6), poor control/adherence (14) or electively (2); and surgery (16) at 12 (6.4-21.3) years for relapse (4), poor control/adherence (5) and electively (7). Adherence problems with thyroxine replacement were reported in 10/33 patients in adulthood.

CONCLUSIONS

Hashimoto's thyroiditis should be distinguished from Graves' disease at diagnosis since the prognosis for remission is better. Remission rates for Graves' disease are low (10/53 patients), time to remission variable and adherence with both ATD and thyroxine replacement often problematic. We recommend (a) the giving of long-term ATD rather than a fixed course of treatment in GD and (b) meticulous and realistic counselling of families from the time of diagnosis onwards.

Osteopathic Manipulative Treatment to Manage Ophthalmic Conditions

Although there is little evidence-based literature regarding osteopathic manipulative treatment for ophthalmic conditions, the general principles and techniques of osteopathic manipulative medicine can be used to manage various ophthalmic pathologic conditions. Additional research to support these treatment options and evaluate the role of OMT as a potential conservative treatment option used by ophthalmologists is needed.

Autoimmune thyroid diseases in children

Autoimmune thyroid diseases (AIT) are common in children and may present with a variety of signs and symptoms including: euthyroid goiter, hypothyroidism, or hyperthyroidism. The natural history of AIT may be different in children but in all age groups, there appear to be genetic risk factors and environmental triggers that initiate thyroid autoimmunity. Areas covered: In this review, we summarize recent studies that investigate the genetics and environmental triggers believed to be involved in thyroid autoimmunity. We also discuss the approach and controversies in the treatment of children with AIT. Expert commentary: Much has been learned about the major roles for genetics, cytokines, regulatory lymphocytes, and environmental triggers in CLT but controversies remain.
