Due to the characteristics of the thyroid gland that prevent infiltration of pathogens, suppurative thyroid gland infections causing thyroid gland abscess are rarely encountered. Herein, we report a young female who presented to our hospital with pulmonary tuberculosis and pneumonia complicated with empyema. During her admission, she developed a rapidly enlarging and tender thyroid gland that produced respiratory obstructive symptoms. Upon clinical examination and radiological imaging, the diagnosis of thyroid abscess was confirmed. Surgical incision and drainage of the abscess was performed along with proper coverage of antibiotics. Thereafter, the patient's clinical status improved dramatically. Although thyroid gland abscesses are rare in clinical practice, a rapidly enlarging thyroid gland in a patient with overt bacterial infection should raise the suspicion of thyroid abscess. Timely diagnosis and proper management can be life-saving in such cases.

BACKGROUND
Pregnancy and delivery markedly influence thyroid function. However, the comparative prevalence of gestational thyrotoxicosis (GT), new onset of Graves' disease during pregnancy (GD during pregnancy), postpartum destructive thyrotoxicosis (PPT), and postpartum Graves' thyrotoxicosis (PPGD) has not yet been determined.
METHODS
We prospectively registered and performed a review of 4127 consecutive non treated female patients with thyrotoxicosis, seen between August 2008 and December 2013 in our outpatient clinic of Kuma Hospital. 187 out of the 4127 women had new diagnosis of thyrotoxicosis during pregnancy or in the postpartum period. We investigated the prevalence of new diagnosis of GT, GD during pregnancy, PPT and PPGD and compared the characteristics of these types of thyrotoxicosis. The postpartum period is defined as twelve months after delivery.
RESULTS
Out of 187 pregnant or postpartum women, we identified 30 (16.0%) with GT, 13 (7.0%) with GD during pregnancy, 42 (22.5%) with PPT, and 102 (54.5%) with PPGD. The onset time of thyrotoxicosis during pregnancy, i.e., both GT and GD during pregnancy, was delayed by a couple of weeks when hCG peaked at 10 gestational weeks. Seventy-six percent of patients with PPT developed thyrotoxicosis between delivery and 4 months postpartum; on the other hand, 83.3% of patients with PPGD developed thyrotoxicosis at 6 months postpartum or later.
CONCLUSIONS
We named gestational thyrotoxicosis, new onset of Graves' disease during pregnancy, postpartum destructive thyrotoxicosis, and postpartum Graves' thyrotoxicosis as pregnancy-associated thyrotoxicosis. A clinically significant number of women developed Graves' disease in the postpartum period in a single thyroid centre.

Review
Genetic factors contribute for about 70% to 80% and environmental factors for about 20% to 30% to the pathogenesis of autoimmune thyroid disease (AITD). Relatives of AITD patients carry a risk to contract AITD themselves. The 5-year risk can be quantified by the so-called Thyroid Events Amsterdam-score, based on serum thyroid-stimulating hormone, thyroid peroxidase (TPO)-antibodies and family history. Subjects at risk may ask what they can do to prevent development of AITD. This review summarizes what is known about modulation of exposure to environmental factors in terms of AITD prevention. To stop smoking decreases the risk on Graves disease but increases the risk on Hashimoto disease. Moderate alcohol intake provides some protection against both Graves and Hashimoto disease. Low selenium intake is associated with a higher prevalence of thyroid autoimmunity, but evidence that selenium supplementation may lower TPO antibodies and prevent subclinical hypothyroidism remains inconclusive. Low serum vitamin D levels are associated with a higher prevalence of TPO antibodies, but intervention studies with extra vitamin D have not been done yet. Stress may provoke Graves hyperthyroidism but not Hashimoto thyroiditis. Estrogen use have been linked to a lower prevalence of Graves disease. The postpartum period is associated with an increased risk of AITD. Taking together, preventive interventions to diminish the risk of AITD are few, not always feasible, and probably of limited efficacy.

Review
Selenium (Se) supplements are commonly prescribed to autoimmune thyroiditis (AIT) patients by European endocrinologists, despite the lack of official guidelines. The majority of Europe is depleted of natural Se sources, and the daily population intake does not comply with recommended values. Optimal individual plasma Se concentration is reached when the selenoproteins (selenoprotein P, glutathione peroxidase) are fully saturated. However, Se intake has to be regulated because both Se shortage and overdose negatively impact health. In the case of AIT, Se may alleviate symptoms or prevent progression to hypothyroidism and postpartum hypothyroidism. Se supplementation in euthyroid, subclinical, or overt hypothyroid AIT patients decreased thyroid autoantibodies, lowered or maintained the TSH level, decreased the fT4/fT3 ratio, reduced the body's oxidative stress and inflammatory status, and amended quality of life and thyroid ultrasound structure and volume. In pregnant females, adequate Se intake protected them against miscarriages, preeclampsia/hypertension, preterm birth, small-for-gestational-age infants' birth, and improved child's neuropsychological development. In the elderly population, adequate Se supplementation decreased cardiovascular diseases and hypertension risk, but prolonged intake of excessive doses increased the all-cause mortality rate. Routine Se supplementation implementation requires from researchers and clinicians consideration of specific populational differences in natural Se and iodine supply, the patient's clinical situation (supplementation simultaneously or before levothyroxine treatment, AIT/non-AIT hypothyroidism), individual response to supplementation (Se and selenoprotein P assessment), predisposition (genetic testing), the status of other trace elements, and the interplay between those micronutrients. Moreover, the safety of commercially available Se formulations, doses, and duration of treatment should be determined. Proper guidelines are warranted to standardise the medical approach to Se supplementation. This article presents a comprehensive review of recent randomised-controlled trials, meta-analyses, and clinical trials concerning the risks and benefits of Se supplementation in different clinical settings and specific populations with particular emphasis on AIT in a practical manner.

The prevalence of postpartum thyroiditis (PPT) averages 5%, with a range from 1% (Thailand) to 22% (Wales, UK, and Liguria, Italy), but 3.6% in another Italian region (Puglia). Evolution of PPT into permanent hypothyroidism (PH) occurs in approximately 50% of cases. Positive thyroperoxidase autoantibodies (TPOAb) in a pregnant woman is a strong predictor of PPT. Because in previous gestational cohorts we found an approximate 12% rate of TPOAb positivity, which compares with 15% in the Liguria cohort and 6% in the Puglia cohort, we hypothesized that the currently unknown prevalence of PPT in Sicily would approximate the said Liguria prevalence. We also explored the predictive value of serum thyroglobulin Ab (TgAb) positivity and ultrasonographic signs suggestive of thyroiditis (UST) at first trimester of gestation for PPT. Of 412 pregnant women who were followed-up for 1 year after delivery, 63 (15.3%) developed PPT, and 54% of them had PH. Gestational rates of TPOAb positivity alone, TgAb positivity alone or UST were 11.4%, 7.8% or 35.0%, with associated PPT rates of 66%, 45% or 36%. TgAb assay allowed detection of 9/63 PPT women (14.3%) who were TPOAb-negative. However, TPOAb remained a better predictor compared to TgAb or UST (odds ratio = 32 10 or 13). Lowering the positivity threshold for either Ab to ≥61 U/ml, Ab-positive were 23.8% of PPT women and 17.7% of pH women. UST was detected in 82.5% of women who developed PPT, precisely 88% of those who evolved into PH and 75.9% of those who did not. Ours is the second study of the new millennium showing a PPT frequency >10%. The dual Ab and lowered threshold strategy correctly predicts more cases of PPT and PH compared to the sole TPOAb strategy. We confirm that half of the PPT women will have PH.

In Europe thyroid ultrasound has been used at outpatient endocrine clinics since many years, and in southern Sweden only during the last years. Ultrasound has a role in the investigation of Graves' disease, subacute thyroiditis, gestational thyrotoxicosis, postpartum thyroiditis, amiodarone thyrotoxicosis and goiter with or without adenoma, but adenomas are usually investigated by endocrine surgeons in Sweden. If widely used the risk for detection of incidentaloma increases. Indications have to be strictly used to avoid further investigations. If an adenoma is localized, the risk for malignancy and requirement of aspiration is estimated by use of the EU-TIRADS classification based on morphology and size. The aspirate is judged by the Bethesda classification, which determines if further investigation is needed. The use of ultrasound at the outpatient clinic has improved the diagnostic quality and follow-up of thyroid patients.

OBJECTIVE
To investigate the effects of haemodynamic indices on colour Doppler ultrasound in differential diagnosis in patients with postpartum thyroiditis and with Graves' disease.
METHODS
The cross-sectional study was conducted at the Endocrinology Polyclinic of Medical Park Hospital, Ordu, Turkey, from March 2017 to May 2018 and comprised patients referred from the Gynaecology Department for routine check-up after parturition within the first 6 months. The patients were divided into two groups. Group 1 had postpartum thyroiditis patients and Group 2 had those of Graves' disease. In both groups, parameters measured were peak systolic velocity, end-diastolic velocity and resistive index of the inferior thyroid artery with proper angle (45-60⁰) on colour Doppler ultrasound. Data was analysed using SPSS 20.
RESULTS
Of the 42 subjects,18(42.85%) were in Group 1 and 24(57.14%) were in Group 2. Peak systolic velocity and end-diastolic velocity values of the inferior thyroid artery were higher in Group 2 compared to Group 1 (p<005). (p<0.05), while the resistive index value was significantly higher in Group 1 compared to Group 2.
CONCLUSIONS
Due to its wide availability, the use of colour Doppler ultrasound parameters indicating parenchymal perfusion were found to be broadly useful in distinguishing between postpartum thyroiditis and Graves' disease.

Thyrotoxicosis can exhibit overlapping symptoms of psychosis in the general population. Each of these pathologies has well-established workups and management. Rare presentations of thyroiditis and psychosis in the postpartum state have been seen in case studies mostly, but data on the prevalence of postpartum psychosis in association with postpartum thyroiditis are not available. Here, we present a unique case of a patient with a history of bipolar disorder who originally presented with postpartum thyroiditis that was worked up and managed appropriately. However, on follow-up, the patient was found to have progressed into prominent psychosis. Both thyroiditis and psychosis were managed individually with full remission upon discharge and is doing well today. The co-occurrence of postpartum psychosis and thyroiditis presents a unique challenge for timely diagnosis and management. We present a case of a young woman initially diagnosed with postpartum thyroiditis needing further management of postpartum psychosis due to persistent symptoms. Clinical presentation supported with a prior history of mood disorder increases the likelihood of these diagnoses together.

The aim of this study was the evaluation of serum C-reactive protein (CRP) concentration as a marker of the inflammatory state in many different thyroid diseases and its dependence on the stage and duration of disease. We conducted a retrospective analysis of 444 randomly selected patients with different kinds of thyroid disease (106 men and 338 women, ranging 18-72 years of age; mean 56.2 ± 5.0 years; median 52 years). Group 1 (G1) comprised 250 patients with hyperthyroidism. Group 2 (G2) consisted of 72 euthyroid patients. Group 3 (G3) consisted of 122 patients with hypothyroidism. Free T4, free T3, and thyrotropin (TSH) levels were measured using the electrochemiluminescent method. Human serum thyroglobulin autoantibodies (Tg-Abs), thyroperoxidase autoantibodies (TPO-Abs), and autoantibodies against the thyrotropin receptor (TSHR-Abs) levels were measured by radioimmunoassay. The high-sensitive CRP (Hs-CRP) level (reference range <3 mg/L) was determined with a highly sensitive latex-based immunoassay. The mean value of Hs-CRP in G1 was 3.6 ± 2.8 mg/L, in G2 2.5 ± 1.5 mg/L and in G3 5.9 ± 5.8 mg/L. Hs-CRP (in mg/L) medians, interquartile and the total ranges in G1 were 3.0 (2.0 [0.1-21.0] 4.0); in G2: 2.3 [1.8 (0.2-9.2) 3.2]; and in G3: 4.3 [2.2 (0.3-31.5) 7.8]. We found statistically significant differences (Kruskal-Wallis test) in serum Hs-CRP values between G1 and G2 (P = 0.007), G1 and G3 (P = 0.001), G2 and G3 (P < 0.001). In G1, statistically significant correlation was confirmed between Hs-CRP and Tg-Abs (r = -0.22, P = 0.0016), CRP and TPO-Abs (r = -0.26, P < 0.001), and also between Hs-CRP and TSHR-Abs (r = -0.18, P = 0.02). In the remaining cases, differences between Hs-CRP and TSH levels (r = -0.09, P = 0.16) were not statistically significant. In G2, no statistically significant correlation was observed: Hs-CRP and Tg-Abs (r = -0.18, P = 0.13), Hs-CRP and TPO-Abs (r = -0.17, P = 0.15), Hs-CRP and TSH (r = 0.01, P = 0.91), Hs-CRP and TSHR-Abs (r = -0.19, P = 0.17). In G3, a statistically significant correlation was confirmed between Hs-CRP and Tg-Abs (r = 0.22, P = 0.012), Hs-CRP and TSH (r = -0.28, P = 0.001). No statistically significant correlation was observed between Hs-CRP and TPO-Abs (r = 0.20, P = 0.06) and between Hs-CRP and TSHR-Abs (r = -0.23, P = 0.11). Hs-CRP is increased in various types of hypothyroidism. This is particularly relevant in postpartum thyroiditis and in patients after radioiodine treatment. The impact of this situation on human health requires further research, however, one might assume that some types of thyroid disease may lead to systemic inflammatory reactions that are reflected in elevated CRP levels.
