RESUMO
INTRODUCTION AND OBJECTIVE: Patients with the 22q11.2 deletion syndrome (22q11DS) frequently display cardiological and psychiatric diseases, but are also at increased risk for endocrine manifestations. The aim of this study was to evaluate the screening, prevalence, and management of hypoparathyroidism and thyroid disease in patients with 22q11DS, to evaluate the metabolic profile, and to compare these results with current literature and guidelines. DESIGN: We performed a retrospective study of patients with genetically confirmed 22q11DS, followed at the center for human genetics of the University Hospitals Leuven, resulting in a cohort of 75 patients. Medical history, medication, and laboratory results concerning hypoparathyroidism, thyroid dysfunction, and the metabolic profile were collected. RESULTS: Of the total cohort, 26 patients (35%) had at least one hypocalcaemic episode. During hypocalcaemia, parathyroid hormone (PTH) was measured in only 12 patients with 11 having normal or low PTH, confirming a diagnosis of hypoparathyroidism. Recurrent episodes of hypocalcaemia occurred in seventeen patients (23%). Adherence to the guidelines was low, with 13% of patients having a yearly serum calcium evaluation, 12% receiving daily calcium supplements, and 20% receiving non-active vitamin D. Hypothyroidism was present in 31 patients (44%) and hyperthyroidism in 6 patients (8%). Information on body mass index (BMI) was available in 52 patients (69%), of which 38% were obese (BMI ≥ 30 kg/m2). CONCLUSION: Hypoparathyroidism, hypothyroidism, and obesity are common endocrine manifestations in patients with 22q11DS but are probably underdiagnosed and undertreated, indicating the need for multidisciplinary follow-up including an endocrinologist.

Background: Children with Down syndrome (DS) are prone to developing autoimmune thyroid disease (AITD). Previous studies found lower selenium (Se) levels in children with AITD. Glutathione peroxidase-3 (GPx3) and selenoprotein-P (SePP) are widely used to measure Se levels. DS children tend to have lower Se levels, the main contributor to hypothyroidism in this population. This study aimed to analyze the Se's role in AITD in Indonesian children with DS. Methods: This cross-sectional study was conducted between February 2021-June 2022 at the Pediatric Outpatient Clinic of Dr Soetomo Hospital. DS children aged 1 month to 18 years were enrolled using consecutive sampling. Thyroid-stimulating hormone, free thyroxine, thyroid peroxidase (TPO-Ab) and thyroglobulin (Tg-Ab) autoantibody, GPx3, and SePP levels were measured in plasma samples using enzyme-linked immunosorbent assays. Statistical analyses used Chi-square, Mann-Whitney, and Spearman's rank correlation (r s). All results with p<0.05 were considered statistically significant. Results: Among 62 children with DS, SePP and GPx3 levels were significantly lower in those with AITD than those without AITD (p=0.013 and p=0.018, respectively). SePP and GPx3 levels correlated significantly with lower TPO-Ab (r s=-0.439 with p=1×10-5 and r s=-0.396 with p=0.001, respectively) and Tg-Ab (r s=-0.474 with p=1×10-5 and r s=-0.410 with p=0.001, respectively) levels. SePP levels correlated significantly with lower thyroid dysfunction incidence (r s=-0.252, p=0.048) in the AITD group. Conclusion: Selenium deficiency contributes to autoimmune process in the thyroid and to thyroid dysfunction in children with Down syndrome. Our findings recommend increasing Se levels through Se-containing foods to reduce the risks of AITD and thyroid dysfunction in DS children with AITD.

COVID-19 represents a worldwide public health emergency, and, beyond the respiratory symptoms characterizing the classic viral disease, growing evidence has highlighted a possible reciprocal relationship between SARS-CoV-2 infection and thyroid dysfunction. The updated data discussed in this review suggests a role of SARS-CoV-2 infection on the thyroid gland, with multiple thyroid pictures described. Conversely, no conclusion can be drawn on the association between pre-existing thyroid disease and increased risk of SARS-CoV-2 infection. In this scenario, selenium (Se), an essential trace element critical for thyroid function and known as an effective agent against viral infections, is emerging as a potential novel therapeutic option for the treatment of COVID-19. Large multicentre cohort studies are required to elucidate the mechanisms underlying thyroid dysfunction during or following recovery from COVID-19, including Se status. Meanwhile, clinical trials should be performed to evaluate whether adequate intake of Se can help address COVID-19 in Se-deficient patients, also avoiding thyroid complications that can contribute to worsening outcomes during infection.

BACKGROUND: Thyroid hormones play a vital role in regulating our body's metabolism. Two important thyroid hormones released from the thyroid gland are tri-iodothyronine (T3) and tetra-iodothyronine (T4). Thyroid-stimulating hormone and thyroid regulating hormone control the T3 and T4 levels in our body. Increased TSH levels indicate hypothyroidism and decreased TSH levels indicate hyperthyroidism. Iodine is a crucial nutrient for the synthesis of thyroid hormones and is mostly obtained from our diet. Other essential nutrients for the thyroid hormones formation include selenium, iron, vitamin D, vitamin B12, etc. Dietary changes in these nutrients can result in alterations in thyroid function and structure. Although normally, the hormonal diseases cannot be cured, but we can improve their signs and symptoms using suitable dietary supplements. OBJECTIVE: The aim of the study was to thoroughly analyze the various benefits and risks associated with the use of dietary supplements for the prevention and treatment of various thyroid disorders, like hypothyroidism, as seen in Hashimoto's thyroiditis; hyperthyroidism, as seen in Graves' disease; sick euthyroidism and subclinical hypothyroidism. METHODS: Literature was searched using the search terms "dietary supplements+thyroid diseases" on Pubmed, Google Scholar, Scopus, Cochrane Library, and other search engines, and data were collected from 1967 to November, 2021, including research inputs from the authors. The literature was thoroughly searched, and deep knowledge was acquired on this topic, which was then sequentially organized and summarized using suitable tables and figures. CONCLUSION: After analyzing various studies on this topic, we arrived at the conclusion that although there are various claimed and observed health benefits of dietary supplements in the prevention and treatment of various thyroid disorders, still several studies have shown too many risks to be associated with the use of dietary supplements, and people using these products should be aware of these risks in order to use them very judiciously for the improvement of their thyroid status.

BACKGROUND: Necrobiosis lipoidica (NL) is a rare granulomatous disorder of unknown aetiology. Randomized controlled studies are not available due to it being an orphan disease. OBJECTIVES: We evaluated patients in 2 dermatological centres to cluster data about epidemiology, the therapeutic approaches for NL, and their efficacy. MATERIALS AND METHODS: Comorbidity and the efficacy of the applied treatment was assessed for 98 patients. RESULTS: We identified 54% of patients with concomitant diabetes and 19% with thyroidal disorders. Topical steroids (85.7%) were predominantly used followed by calcineurin inhibitors (31%) and phototherapy (41.8%). Systemically, fumaric acid esters were more frequently applied (26.8%) than steroids (24.4%) and dapsone (24.4%). Steroids, compression therapy, calcineurin inhibitors, phototherapy, fumaric acid esters, and dapsone showed remarkable efficacy. CONCLUSION: Therapeutic options were chosen individually in accordance with the severity of NL and presence of ulceration. Topical calcineurin inhibitors, systemic application of fumaric acid esters, and dapsone represent effective alternatives to the use of steroids.

Adequate iodine intake is necessary for normal thyroid function. Iodine deficiency is associated with serious complications, but also iodine excess can lead to thyroid dysfunction, and iodine supplementation aimed to prevent iodine deficiency disorders has been associated with development of thyroid autoimmunity. The epidemiology of thyroid diseases has undergone profound changes since the implementation of iodoprophylaxis, notably by means of iodine-enriched salt, specifically resulting in decreased prevalence of goiter and neonatal hypothyroidism, improved cognitive function development in infancy, and reduced incidence of more aggressive forms of thyroid cancer. The main question we address with this review is the clinical relevance of the possible effect on autoimmunity exerted by the use of iodine-enriched salt to correct iodine deficiency. In animal models, exogenous iodine is able to trigger or exacerbate thyroid autoimmunity, but it is still not clear whether the observed immunological changes are due to a direct effect of iodine on immune response, or whether they represent a secondary response to a toxic effect of iodine on thyroid tissue. Previous iodine status of a population seems to influence the functional thyroid response to increased iodine intake and possibly the development of thyroid autoimmunity. Moreover, the prevalence of thyroid antibodies, regarded as hallmark of autoimmune thyroid disease, varies between populations under the influence of genetic and environmental factors, and the presence of thyroid antibodies does not always coincide with the presence of thyroid disease or its future development. In addition, the incidence of autoimmune diseases shows a general increasing trend in the last decades. For all these reasons, available data are quite heterogeneous and difficult to analyze and compare. In conclusion, available data from long-term population surveys show that a higher than adequate population iodine intake due to a poorly controlled program of iodine prophylaxis could induce thyroid dysfunction, including thyroid autoimmunity mostly represented by euthyroid or subclinical hypothyroid autoimmune thyroiditis. Close monitoring iodine prophylaxis is therefore advised to ensure that effects of both iodine deficiency and iodine excess are avoided.

BACKGROUND: Thyroid dysfunction has been observed in patients with COVID-19, and endocrinologists are requested to understand this clinical issue. Pandemic-related restrictions and reorganization of healthcare services may affect thyroid disease management. OBJECTIVE AND METHODS: To analyze and discuss the relationship between COVID-19 and thyroid diseases from several perspectives. PubMed/MEDLINE, Google Scholar, Scopus, ClinicalTrial.gov were searched for this purpose by using free text words and medical subject headings as follows: "sars cov 2", "covid 19", "subacute thyroiditis", "atypical thyroiditis", "chronic thyroiditis", "hashimoto's thyroiditis", "graves' disease", "thyroid nodule", "differentiated thyroid cancer", "medullary thyroid cancer", "methimazole", "levothyroxine", "multikinase inhibitor", "remdesivir", "tocilizumab". Data were collected, analyzed, and discussed to answer the following clinical questions: "What evidence suggests that COVID-19 may induce detrimental consequences on thyroid function?"; "Could previous or concomitant thyroid diseases deteriorate the prognosis of COVID-19 once the infection has occurred?"; "Could medical management of thyroid diseases influence the clinical course of COVID-19?"; "Does medical management of COVID-19 interfere with thyroid function?"; "Are there defined strategies to better manage endocrine diseases despite restrictive measures and in-hospital and ambulatory activities reorganizations?". RESULTS: SARS-CoV-2 may induce thyroid dysfunction that is usually reversible, including subclinical and atypical thyroiditis. Patients with baseline thyroid diseases are not at higher risk of contracting or transmitting SARS-CoV-2, and baseline thyroid dysfunction does not foster a worse progression of COVID-19. However, it is unclear whether low levels of free triiodothyronine, observed in seriously ill patients with COVID-19, may worsen the disease's clinical progression and, consequently, if triiodothyronine supplementation could be a tool for reducing this burden. Glucocorticoids and heparin may affect thyroid hormone secretion and measurement, respectively, leading to possible misdiagnosis of thyroid dysfunction in severe cases of COVID-19. High-risk thyroid nodules require a fine-needle aspiration without relevant delay, whereas other non-urgent diagnostic procedures and therapeutic interventions should be postponed. DISCUSSION: Currently, we know that SARS-CoV-2 could lead to short-term and reversible thyroid dysfunction, but thyroid diseases seem not to affect the progression of COVID-19. Adequate management of patients with thyroid diseases remains essential during the pandemic, but it could be compromised because of healthcare service restrictions. Endocrine care centers should continuously recognize and classify priority cases for in-person visits and therapeutic procedures. Telemedicine may be a useful tool for managing patients not requiring in-person visits.

Purpose: To investigate whether patients with thyroid disease are at increased risk of uveitis.Methods: Data was collected from the Taiwan National Health Insurance system and included patients newly diagnosed with thyroid disease from 2000 to 2012. The endpoint of interest was a diagnosis of uveitis.Results: In analyzing 21,396 patients with thyroid disease, yielding 85,584 matched comparisons, patients with thyroid disease to have a significantly higher cumulative incidence of uveitis when compared to the control cohort with the Kaplan-Meier analysis. This result was further confirmed by Cox regression analysis. The increased risk was persistent in both genders. The association between thyroid disease and uveitis was stronger in patients without diabetes or hypertension.Conclusion: Patients with thyroid disease were found to have a higher risk for uveitis. For certain age groups or patients without diabetes or hypertension, the role of thyroid disease might be more crucial for uveitis development.

OBJECTIVE: The aim of this study is to investigate the association between oral lichen planus (OLP) and a variety of systemic conditions, medication, and supplement usage. MATERIALS AND METHOD: A total of 156 patients diagnosed with OLP and 156 controls at Columbia University Irving Medical Center from 2000 to 2013 were selected as part of the matched (1:1) case-control study. Demographics, systemic conditions, prescription medications and supplements were extracted from the patients' medical records. A univariable conditional logistic regression (CLR) analysis was performed to calculate unadjusted odds ratio, to identify significant variables associated with OLP (p < .10). Significant variables were further tested using multivariable CLR analysis with both forward and backward selection to calculate adjusted odds ratio (aOR) and further distinguish variables associated with OLP (p < .05). RESULTS: This analysis identified six significant variables: thyroid disorder (aOR:5.1,95%CI:2.3-11.2), any form of cancer (aOR:3.4,95%CI:1.4-8.4), type 2 diabetes (aOR:2.8,95%CI:1.2-6.3), hyperlipidemia (aOR:2.3,95%CI:1.3-4.1), oral sedative usage (aOR:6.3,95%CI:1.8-22.5), and vitamin D supplementation (aOR:2.7,95%Cl:1.3-6.0). CONCLUSION: Thyroid disorders, cancer, type 2 diabetes, hyperlipidemia, sedatives, and vitamin D supplementation were found to be associated with OLP. Additional investigation is required to explore these associations, which could shed light on the potential mechanism of OLP and reinforce the idea that oral lesions could be predicative of previously undetected systemic conditions.

Little is known about iodine adequacy and gestational thyroid disorders (GTDs) in Saudi Arabia. This study measured the rates of GTDs and iodine adequacy in 810 healthy Saudi women. Concentrations of serum thyroid hormones and 24-h urine iodine (24-h UIC), and GTDs were diagnosed according to the American Thyroid Association guidelines. Dietary and socioeconomic data to determine factors associated with GTDs and iodine insufficiency were collected. GTDs were detected in 265 women (32.7%) as follows: subclinical (SCH; 20.2%) and overt (OH; 5.8%) hypothyroidism, isolated hypothyroxinemia (ISH; 4.7%) and hyperthyroidism (2%). The SCH (109.2 µg/L; IQR: 77.2-149.7), OH (95.3 µg/L; IQR: 74.3-130.5) and ISH (107.3 µg/L; IQR: 65.5-133.1) groups had median 24-h UIC below the WHO recommended limit, whereas the euthyroid (191.4 µg/L; IQR: 170.03-219.8) and hyperthyroid (159.5 µg/L; IQR: 152.9-238.3) groups were iodine sufficient. Numbers of pregnancies, less education, not consuming iodized salt and not using iodine supplements increased risk of hypothyroidism and ISH. Contrariwise, interval ≥ 3 years from last pregnancy and higher 24-h UIC decreased odds of hypothyroidism and ISH. Moreover, dairy products and egg consumption were markedly lower in all GTD groups. Dairy products and seafood consumption correlated independently with 24-h UIC of the study participants, whereas consuming yogurt, eggs, redfish and shellfish protected against GTDs. In conclusion, GTDs appear to be prevalent in pregnant Saudi women and the hypothyroid and hypothyroxinemia groups had iodine insufficiency. However, consuming iodized salt, iodine supplements, dairy products, seafoods and eggs may protect against GTDs.

Background The thyroid gland of patients with congenital heart disease may be exposed to large doses of iodine from various sources. We assessed the thyroid response after iodine exposure during conventional angiography in cardiac catheterization and angiographic computer tomography in childhood. Methods Retrospective mid- to long-term follow-up of 104 individuals (24% neonates, 51% infants, 25% children) with a median age and body weight of 104 days [0-8 years] and 5.3 kg [1.6-20]. Serum levels of thyroid-stimulating hormone, free triiodthyronine and free thyroxine were evaluated at baseline and after excess iodine. We also assessed risk factors that may affect thyroid dysfunction. Results Baseline thyroidal levels were within normal range in all patients. The mean cumulative iodinate contrast load was 6.6 ± 1.6 mL/kg. In fact, 75% had experienced more than one event involving iodine exposure, whose median frequency was three times per patient [1-12]. During the median three years follow-up period [0.5-10], the incidence of thyroid dysfunction was 15.4% (n=16). Those patients developed acquired hypothyroidism (transient n=14, long-lasting n=2 [both died]) with 10 of them requiring temporary replacement therapy for transient thyroid dysfunction, while four patients recovered spontaneously. 88 individuals (84.6%) remained euthyroid. Repeated cardiac interventions, use of drugs that interfere with the thyroid and treatment in the intensive care unit at the index date were strong predictors for acquired thyroid dysfunction. Conclusions The incidence of acquired hypothyroidism after iodine excess was 15.4%. However, most patients developed only transient hypothyroidism. Systemic iodine exposure seems to be clinically and metabolically well tolerated during long-term follow-up.

A healthy gut microbiota not only has beneficial effects on the activity of the immune system, but also on thyroid function. Thyroid and intestinal diseases prevalently coexist-Hashimoto's thyroiditis (HT) and Graves' disease (GD) are the most common autoimmune thyroid diseases (AITD) and often co-occur with Celiac Disease (CD) and Non-celiac wheat sensitivity (NCWS). This can be explained by the damaged intestinal barrier and the following increase of intestinal permeability, allowing antigens to pass more easily and activate the immune system or cross-react with extraintestinal tissues, respectively. Dysbiosis has not only been found in AITDs, but has also been reported in thyroid carcinoma, in which an increased number of carcinogenic and inflammatory bacterial strains were observed. Additionally, the composition of the gut microbiota has an influence on the availability of essential micronutrients for the thyroid gland. Iodine, iron, and copper are crucial for thyroid hormone synthesis, selenium and zinc are needed for converting T4 to T3, and vitamin D assists in regulating the immune response. Those micronutrients are often found to be deficient in AITDs, resulting in malfunctioning of the thyroid. Bariatric surgery can lead to an inadequate absorption of these nutrients and further implicates changes in thyroid stimulating hormone (TSH) and T3 levels. Supplementation of probiotics showed beneficial effects on thyroid hormones and thyroid function in general. A literature research was performed to examine the interplay between gut microbiota and thyroid disorders that should be considered when treating patients suffering from thyroid diseases. Multifactorial therapeutic and preventive management strategies could be established and more specifically adjusted to patients, depending on their gut bacteria composition. Future well-powered human studies are warranted to evaluate the impact of alterations in gut microbiota on thyroid function and diseases.

OBJECTIVES: to evaluate the implementation of an integrated care model for thyroid disease on thyroid surgery at the University Hospital "Federico II" of Naples (Campania Region, Southern Italy). DESIGN: quasi-experimental design employing an interrupted time series analysis. SETTING AND PARTICIPANTS: all subjects who were admitted to the University Hospital "Federico II" for thyroid surgery between January 2008 and December 2018. The integrated care model for thyroid disease was implemented starting from January 2016. MAIN OUTCOME MEASURES: rate of partial thyroidectomies over all thyroidectomies; rate of diagnosed thyroid cancers over all diagnosed thyroid tumours; length of stay (LOS). Differences pre- and post-interventions were assessed employing Poisson (for count outcomes) and linear (for continuous outcomes) regression models. Models were adjusted for age, gender, tumour diagnosis (none, benign, malignant), Charlson index, and discharge month. RESULTS: data on 4,233 thyroidectomies were included. There was no difference between pre- and post-intervention trends for the rate of partial thyroidectomies over all thyroidectomies (pre-intervention: IRR 1.00; 95%CI 0.99;1.00 - post-intervention: IRR 1.00; 95%CI 0.98;1.02) and for the rate of diagnosed thyroid cancers over all thyroid tumours (pre-intervention IRR 0.99; 95%CI 0.99;1.00 - post-intervention IRR 1.00; 95%CI 0.99;1.01). On the contrary, the LOS reduced from 4.5 (±4.3) days in 2008 to 3.2 (±3.2) days in 2018. The multivariate analysis confirmed this reduction, estimated to be 1.1 days on average in the pre-intervention eight-year period (pre-intervention coefficient -0.01; 95%CI -0.02;-0.01), followed by an even greater reduction in the post-intervention three-year period which was estimated to be 1.1 day (post-intervention: coefficient -0.03; 95%CI -0.05;-0.01). CONCLUSIONS: the implementation of an integrated care model for thyroid disease contributed to reduce the LOS for thyroidectomies, improving the efficiency in the management of thyroid disease. However, this intervention had no impact in reducing the rate of total thyroidectomies.

OBJECTIVES: Postnatal thyroid dysfunction is common in preterm infants but the relationship between mild dysfunction and neurodevelopment is unclear. Our aim is to describe the relationship between thyroid function and neurodevelopment. DESIGN: Cohort analysis. PATIENTS: 1275 infants born under 31 weeks' gestation; there were no exclusion criteria. SETTING: The infants were part of a UK daily iodine supplementation trial. MAIN OUTCOMES: Thyroid-stimulating hormone, thyroid-binding globulin and total thyroxine levels were measured in dried blood spots on postnatal days 7, 14, 28 and the equivalent of 34 weeks' gestation. Neurodevelopment was measured using the Bayley-III Scales of infant development at 2 years of age. RESULTS: No infant was identified as hypothyroid through routine screening. The 3% of infants consistently in the top decile of gestationally age-adjusted thyroid-stimulating hormone levels had a reduction in cognitive score of 7 Bayley units when compared with those not in the top decile (95% CI -13 to -1). A reduction in motor composite score of 6 units (95% CI -12 to <-0.1) and fine motor score of 1 unit (95% CI -2 to -0.1) was also identified. The 0.7% of infants consistently in the bottom decile of age-adjusted thyroxine levels had a reduction in motor composite score of 14 units (95% CI -25 to -2) and its two subset scores, fine and gross motor, of 2 units (95% CI respectively -4.5 to <-0.1 and -4.3 to -0.3). CONCLUSIONS: Preterm infants with consistent 'mild' thyroid dysfunction score less on neurodevelopmental tests at 2 years of age. Many of these infants will not be detected by current clinical protocols or screening programmes.

BACKGROUND: Thyroid gland is a probable goal tissue for radiation-related injury. Occupational exposure to ionizing radiation leads to thyroid dysfunction and exposure to high dose may lead to thyroid carcinoma. OBJECTIVE: Evaluation of the role of Thyroid peroxidase antibody as a predictor for thyroid dysfunction among nurses and technicians in the radiology department in Mansoura Specialized Medical hospital (MSMH). SUBJECTS AND METHODS: Subjects were Nurses and technicians who are working in (MSMH) with persistent daily duty in the last 3 years and fulfilling the inclusion and exclusion criteria. All subjects included in the study were recruited in one month and divided into two groups; Group 1: 50 subjects who were working in radiology, coronary angiography and ERCP unit, Radiation -exposed group. Group 2: 33 subjects who were working in In-patient departments and in out- patient clinics and not exposed to any type of radiation. Non fasting blood sample was taken from all enrolled subjects for measurement of TSH and Anti-TPO. RESULTS: TPO was positively and significantly correlated to age, TSH, duration of radiology/ y (r=0.388, 0.364, 0.342respectively) p value <0.05. Roc curve was done to detect the sensitivity and specificity of TSH in relation to TPO that revealed the cutoff value of TSH > 1.69 with Sensitivity and Specificity. PPV, NPV and accuracy at cutoff >1.69 were 70.6%, 51.5%, 42.8%, 77.3% and 58%. CONCLUSION: Working personnel with positive anti TPO and their TSH levels are more than 1.69 associated with symptoms of hypothyroidism, a trial of treatment is mandatory to relieve symptoms.

The influence of melasma risk factors on the effectiveness of laser toning treatment in Venezuelan females was investigated. Clinical evaluation was performed (n = 64) including ultrasound and thyroid hormone profile. All patients underwent face exposure with laser toning, eight sessions weekly. VISIA percentiles corresponding to dark brown spots determined before and after treatment were compared by ANOVA. Differences between percentile values before and after treatment for each patient were calculated and expressed as percentages. An improvement of ≥30% was considered as significant. Spearman rank correlations between improvement and clinical parameters were determined. A significant increase (p > .005) of the median of the percentiles in the overall group was observed. However, only 62.5% of the patients exhibited an improvement of ≥30% at the right malar, 73.4% at the frontal and 71.8% at the left malar areas. Hormonal contraception during treatment (right malar: p < .0001 left malar: p = .0035), thyroid disorders (right malar: p < .0001; frontal: p = .011; left malar: p < .0001) and photoaging (right malar: p = .0235; frontal: p = .0237; left malar: p = .0137) were inversely associated to melasma improvement after treatment. Prolonged use of sunscreen improved significantly (right malar: p < .001; frontal: p = .016 and left malar: p = .025) treatment effectiveness.

Hypothyroidism is one of the common endocrine complications described in patients with ß-thalassemia major (ß-TM). Studies have reported its incidence and severity depending on the region, quality of management and treatment protocols. The reported thyroid dysfunction includes overt hypothyroidism, subclinical hypothyroidism and rarely, central hypothyroidism. The main aims of this study were to identify the incidence of hypothyroidism in 82 patients with ß-TM in Syria, and also to evaluate the effect of compliance with deferoxamine (DFO) therapy on the patients' thyroid function. Out of the 82 patients included in this study, 24 had subclinical hypothyroidism (29.27%) and one patient had overt hypothyroidism (1.22%). It was demonstrated by this study that noncompliance with DFO therapy increases the risk of thyroid dysfunction 6.38-times compared to compliance with DFO [risk ratio (RR) = 6.385; 95% confidence interval (95% CI) 2.40-16.95)]. These results emphasize the importance of compliance with chelation therapy to minimize the burden of thyropathy on patients' quality of life, and also augment the rationale for a routine follow-up and endocrine evaluation for early detection and management of these complications.

BACKGROUND AND OBJECTIVES: In Australia, two public health measures were introduced between 2009 and 2010 to reduce iodine deficiency. However there has been a shortage of information regarding their effectiveness and the ongoing prevalence of iodine deficiency in Australia. The primary aim of this study was to assess the extent to which these public health measures have reduced rates of iodine deficiency among pregnant and lactating women. METHODS AND STUDY DESIGN: A review was conducted to identify all studies published since January 2010 that quantitatively measured the iodine status of pregnant and/or lactating women in Australia. RESULTS: We found 25 publications, of which seven were included in this review after our exclusion criteria were applied. Of the seven included publications, three demonstrated the pregnant and lactating women in their studies to be iodine replete (median urinary iodine concentrations (MUIC) greater than 150 µg/L, or a breast milk iodine concentration (BMIC) of greater than 100 µg/L). The remaining four publications found MUIC of pregnant and lactating women to be below the 150 µg/L threshold, in the mild-to-moderate iodine deficiency category. Only two studies, documented iodine sufficiency among pregnant and lactating women in the absence of iodine supplementation. CONCLUSIONS: Many pregnant and lactating women in Australia remain at least mildly iodine deficient. Antenatal iodine supplementation was the factor most consistently associated with an adequate iodine status. Larger, more representative studies or sentinel studies with a National coordination are needed to understand the differences in iodine status that exist across the country.

Objectives: As the relationship between diabetes mellitus and thyroid dysfunction is well known, it is important to investigate the factors influencing this association. Continuity of care is associated with better quality of care and outcomes, such as reduced complications, among diabetes patients. Therefore, the purpose of this study was to investigate the association between continuity of care and the onset of thyroid dysfunction among diabetes patients. Methods: We used Korean National Health Insurance Service National Sample Cohort data from 2002 to 2013. Our final study population included 16,806 newly diagnosed diabetes patients who were older than 45 years of age. Continuity of care was measured using the Continuity of Care index. The dependent variable was the onset of thyroid disorder. Cox proportional hazard regression models were used for statistical analyses. Results: Diabetes patients with low continuity of care were at increased risk of the onset of thyroid disorder compared with those with high continuity of care (hazard ratio (HR): 1.28, 95% confidence interval (CI): 1.07â»1.54). Subgroup analyses showed that this association was significant within patients with type 2 diabetes (HR: 1.24, 95% CI: 1.01â»1.52) or whose main attending site was a local clinic (HR: 1.32, 95% CI: 1.07â»1.64). Conclusions: Our results show that diabetes patients with low continuity of care are more likely to experience the onset of thyroid disorder. Therefore, improving continuity of care could be a reasonable method of preventing complications or comorbidities, including thyroid disorder, among diabetes patients.

PURPOSE: Iodine deficiency still remains a significant health issue worldwide. Pregnant and lactating women are at risk for iodine deficiency when living in mild iodine-deficient areas such as Italy. This study aims at evaluating the consumption of iodized salt, iodine-rich-foods and maternal micronutrient supplements in a group of women with limited access to the Italian National Health System. METHODS: A cross-sectional survey was conducted among immigrant and Italian women living in poverty and referring to 40 Non-Governmental Organization throughout Italy for their health needs. 3483 women answered the ad hoc questionnaire between January 2017 and February 2018. RESULTS: The consumption of iodized salt was very low, and even lower among immigrant women. Determinants of iodized salt consumption were the period spent in Italy for immigrant women and living in a family-type setting, parity and, particularly, the degree of education for Italian ones. 17.5% of immigrant women and 8.6% of the Italian ones reported a diagnosis of thyroid disease. 521 women, 75.4% of whom were immigrants, were pregnant or breast-feeding. The majority (57.3%) had no specific maternal supplementation. CONCLUSIONS: Both Italian and immigrating women with a low income or without access to the public health system have a poor adherence both to the salt iodization policy and to folic acid and iodine supplements in preconception and pregnancy. They also referred a low-frequency intake of iodine-rich-foods. The identification of barriers to health care access could be useful to promote specific health interventions in this target population.
