David Blank
Predation is usually the primary cause of infant death among ungulate species, with the annual variation in the survival of neonates over their first summer a major factor in the population dynamics of many ungulates. Consequently, the maternal rearing strategy of a species is crucial for its reproductive success. Since the roles mothers and fawns play in the implementation of antipredator strategies in hider species have been poorly understood until now, this paper considers this behavior in the goitered gazelle, which is a typical hider species...

Italy is dealing with iodine deficiency since ancient times. Indeed, iodine deficiency disorders, specifically goiter and cretinism, have been reported in some regions of Northern Italy already in the first century AD. However, a clear relationship between endemic goiter and endemic cretinism was recognized only in 1848 by an "ad hoc" committee appointed by the king of Sardinia, which identified extensive areas afflicted by these disorders in Piedmont, Liguria and Sardinia. With the identification in the early 20th century of iodine deficiency as the cause of endemic goiter1 many epidemiological studies were conducted in Italy...

The new Italian cytological classification (SIAPEC 2014) of thyroid nodules, in line with those of Bethesda and BTA-RCPath, replaces the previous TIR3 class with two new classes (TIR3A and TIR3B), which correspond to different risks of malignancy and clinical actions required. The present study was conducted to evaluate the diagnostic accuracy of the new SIAPEC classification as opposed to its previous version (SIAPEC 2007). Preoperative cytology was compared with the final histology obtained from 650 consecutive patients who underwent total thyroidectomy for multinodular goiter...

BACKGROUND: Postoperative hypocalcemia is the most common complication after total thyroidectomy. Postoperative parathyroid hormone (PTH) measurement is one of the methods to detect or prevent postoperative hypocalcemia. Prophylactic oral calcium supplementation is another method to prevent early postoperative hypocalcemia. The aim of this study is to detect the accurate timing of PTH and evaluate efficacy of routine oral calcium supplementation for postoperative hypocalcemia. METHODS: A total of 106 patients were performed total thyroidectomy...

Takotsubo cardiomyopathy is increasingly recognized as a distinct clinical entity. An association with thyroid disease has been identified in several case reports, mostly in the context of Grave disease. We report the case of a 67-year-old woman presenting with takotsubo cardiomyopathy and thyrotoxicosis secondary to toxic multinodular goiter. Previously unreported, this suggests that this association is related to the direct effects of thyroid hormone, rather than an autoimmune mechanism. Thyroid disease should be considered in patients presenting with takotsubo cardiomyopathy...

Randolph W Evans, Josefine S Timm
A 33-year-old female is presented with the first case to our knowledge of new daily persistent headache (NDPH) with a large right benign non-toxic multinodular goiter causing carotid and vertebral compression with complete resolution of the headache immediately after thyroidectomy. Although this may be quite rare, hypothyroidism or hyperthyroidism causing NDPH, migraine, or an exacerbation of pre-existing migraine is not. Clinicians should consider routinely obtaining serum thyroid-stimulating hormone (TSH) and free T4 in patients with new onset frequent headaches or an exacerbation of prior primary headaches...

PURPOSE: The characteristics of fetal thyroid on magnetic resonance (MR) imaging, including normal thyroid and disorders other than goiter have not been fully evaluated. Our aim was to assess fetal thyroid using three dimensional (3D) gradient echo (GRE) T1-weighted MR imaging and to examine the usefulness of this modality. MATERIALS AND METHODS: The study included 27 3D GRE T1-weighted images from 26 fetuses. The largest possible region of interest (ROI) within the thyroid at the slice level depicting the thyroid was manually defined and three circular ROIs on neck muscle were manually defined on the image slices showing the highest signal intensity (SI) of the thyroid...

Dilational tracheotomy is a minimally invasive method that can be performed at the bedside on patients requiring long-term mechanical ventilation. In our 70-year-old male patient, percutaneous dilational tracheotomy (Ciaglia Blue Rhino, Cook Medical Inc., Bloomington, Indiana, United States) was performed because of bilateral pneumonia with sepsis. There were no initial problems. Nine days later, while the patient was being repositioned, the tracheal cannula became dislocated. Despite extending the cervical incision it was not possible to recannulate...

MicroRNAs (miRNAs) are important post-transcriptional regulators of gene expression that modulate the vast majority of cellular processes. During development, the correct timing and expression of miRNAs in the tissue differentiation is essential for organogenesis and functionality. In thyroid gland, DICER and miRNAs are necessary for accurately establishing thyroid follicles and hormone synthesis. Moreover, DICER1 mutations and miRNA deregulation observed in human goiter influence thyroid tumorigenesis. The thyroid malignant transformation by MAPK oncogenes is accompanied by global miRNA changes, with a marked reduction of "tumor-suppressor" miRNAs and activation of oncogenic miRNAs...

BACKGROUND: The most appropriate surgical procedure for multinodular goiter (MNG) remains under debate. Incidental thyroid carcinoma (ITC) is often identified on histopathological examination after thyroidectomy performed for presumed benign MNG. AIM OF THE STUDY: The aim of the study was to determine the value of radical surgery for MNG patients considering the prevalence of ITC diagnosed postoperatively. MATERIALS AND METHODS: We conducted retrospective analysis of the medical records of 2,306 patients surgically treated for MNG between 2008 and 2013 at one center...

Water-clear cell adenoma (WCCA) of the parathyroid gland is an exceedingly rare neoplasm. To date, 17 cases have been reported in the literature, with only one of them being intrathyroidal. Here we report a case of a 34-year-old woman who presented for evaluation of a goiter and was found to have a thyroid nodule and abnormal thyroid function tests (TFT). Fine needle aspiration biopsy of the nodule revealed thyroid follicular cells without atypia and subsequent Afirma® Gene Expression Classifier (GEC) testing results were suspicious for malignancy...

Iodine nutrition is a result of geological conditions, iodine fortification and monitoring strategies within a country together with the dietary habits of the population. This review summarizes the basis for the current iodine situation in the Scandinavian countries in order to identify gaps in knowledge, determine necessary future steps, highlight landmarks in Scandinavian iodine research and consider ongoing studies in Scandinavian countries with high international impact. Historically, iodine deficiency disorders such as goiter were common in Norway and Sweden, but not in Denmark...

Iodine deficiency disorders (IDD) still represent a major public health problem, with almost 30% of the world population being exposed to the consequences of nutritional iodine deficiency (ID). In Italy, despite a sustained policy of iodine prophylaxis, more than 10% of people is still affected with goiter, and a presumably higher rate of subjects may suffer from minor cognitive deficits due to inadequate iodine supply during antenatal life. This review of systematic observational studies carried out over thirty-five years (1980-2015) in a sentinel ID area in North-eastern Sicily highlights the changing phenotypes of IDD in this region...
