BACKGROUND: Dichlorodiphenyldichloroethene (p,p´-DDE), the main metabolite of dichlorodiphenyltrichloroethane (DDT), has been associated with changes in human thyroid hormone levels. Maternal thyroid hormones are essential for adequate fetal neurodevelopment during the first half of pregnancy. OBJECTIVE: To evaluate the association between maternal p,p´-DDE concentration and the maternal thyroid profile during the first half of pregnancy. MATERIALS AND METHODS: We analyzed the information of 430 pregnant women from a Mexican floriculture area, with a gestational age ≤16 weeks...

BACKGROUND: Chronic supplementation can suppress the hypothalamic-pituitary-thyroid axis (HPTA) and make it difficult to assess thyroid function after withdrawal of levothyroxine. OBJECTIVES: To determine whether the HPTA is suppressed after levothyroxine administration in euthyroid dogs and the time required for resolution of any suppression. ANIMALS: Twenty-eight healthy euthyroid dogs. METHODS: A prospective, randomized study administering levothyroxine to euthyroid dogs for 8 weeks (group 1) or 16 weeks (group 2)...

INTRODUCTION: chronic urticaria (CU) is a skin disorder characterized by transient, pruritic wheals persisting for longer than 6 weeks. The etiopathogenesis of the disease is still unclear, but there is evidence that autoimmunity and endocrine dysfunction may be involved. AIM: the aim of this study was to determine whether chronic urticaria is statistically associated with thyroid autoimmunity. PATIENTS AND METHODS: in a prospective case-control study, we compared the frequency of thyroid auto-antibodies (thyroglobulin antibody, anti-Tg and thyroid peroxidase antibody, anti-TPO) in 70 patients with chronic urticaria and in 70 healthy volunteers...

Shinji Higuchi, Masaki Takagi, Yukihiro Hasegawa
There have been reports of the use of levothyroxine or levothyroxine plus liothyronine for consumptive hypothyroidism caused by hepatic hemangiomas. Administration of levothyroxine without liothyronine can be inadequate to maintain normal levels of both free T3 and free T4 in some patients. However, there is no report of treatment with liothyronine plus propranolol. We herein present a case in which we used liothyronine therapy for multifocal hepatic hemangiomas in a Japanese patient with low free T3 and normal free T4 levels...

Hysterosalpingography (HSG) using iodinated contrast medium is X-ray diagnostic test that examines the inside of the uterus and fallopian tubes in infertile women. In this study, we compared thyroid function (thyroid stimulating hormone: TSH and free-T4: FT4 levels) after HSG with an oil-soluble contrast medium (OSCM) and a water-soluble contrast medium (WSCM). One hundred and sixty-four and 94 patients with normal thyroid function received HSG with OSCM and WSCM, respectively. Approximately 25% of the women in the OSCM group developed subclinical hypothyroidism (SCH), whereas only less than 10% of the patients in the WSCM group developed SCH...

BACKGROUND: To analyze predictive factors suggesting transient congenital hypothyroidism (TCH) compared to permanent congenital hypothyroidism (PCH) or transient thyroid function test (TFT) abnormalities among children who had positive screening results at our centers over the past decade. METHODS: A retrospective chart review of 105 subjects who presented elevated TSH levels on a newborn screening test (NST) was done. TCH was defined when a trial-off therapy was successful, and PCH was defined when a trial failed or when the subject was kept on medication beyond 3 years of age...

INTRODUCTION: There is evidence, though not consistent, that offspring born to mothers with subtle decreases in thyroid function early in their pregnancies may be at risk of cognitive impairments and attention problems. However, other types of problem behavior have not been addressed thus far. We tested whether maternal thyroid function in early pregnancy is associated with several types of problem behavior in offspring at age 5-6 years. METHODS: This was a longitudinal study that included the data of 2000 mother-child pairs from the Amsterdam Born Children and their Development study...

BACKGROUND: Maternal supply of thyroid hormones during pregnancy serves a critical role in fetal development. Although animal and in vitro studies provide evidence for thyroid hormone disruption as a result of bisphenol A (BPA) exposure, there is still a lack of evidence in human studies, particularly in the context of pregnancy. OBJECTIVES: We aimed to explore the associations between urinary BPA concentrations and plasma thyroid hormone parameters during gestation in pregnant women, and also investigated potential windows of vulnerability during gestation...

BACKGROUND: Whether serum TSH undergoes seasonal fluctuations in euthyroid and hypothyroid residents of temperate climates is controversial. METHODS: Monthly TSH and thyroid hormone levels were cross-sectionally analyzed in a large cohort of euthyroid subjects (n=11,806) and L-thyroxine (L-T4)-treated athyreotic patients (n=3,934). Moreover, in a small group (n=119) of athyreotic patients treated with an unchanged dosage of L-T4 monotherapy, hormones were measured both in the coldest and the hottest seasons of the same year (longitudinal study)...

BACKGROUND: Thyroid disorders are common during pregnancy. To date, a limited number of studies have reported differences in serum thyroid hormone concentrations between different ethnic groups. We sought to establish gestational age-specific reference intervals for serum levels of thyroid hormones in a multi-ethnic population and investigate whether separate reference intervals should be used for different ethnic groups. METHODS: A total of 926 pregnant women from multiple ethnic groups attended four separate study visits spanning the three trimesters...

Sepsis is a systemic inflammatory response syndrome with high mortality, which results from severe infection and can lead to secondary organ dysfunction. It is one of the most common cause of death in intensive care unit. Clinical reports have shown that sepsis was often accompanied by thyroid dysfunction, which is called "low triiodothyronine (T3)" syndrome and characterized by decreased blood total T3 and free T3, and by normal or decreased thyroxine (T4) and thyroid stimulating hormone (TSH). This syndrome may greatly affect the prognosis of patients with sepsis...

We describe the case of four patients consulting for headache and tachycardia of brutal onset. Their biological data were compatible with primary hyperthyroidism with low TSH and high T4 serum levels. Serum thyroglobulin level was low and Tc-scintigraphy showed decreased uptake with a homogenous pattern. These results allowed to conclude a thyrotoxicosis caused by thyroid hormones intake. History taking revealed consumption of beef neck meat containing all or parts of the bovine thyroid gland. Evolution was favourable with beta-blockers...
