Twenty-two paragangliomas from different anatomical sites and 24 thymic neuroendocrine carcinomas (carcinoid tumors) were analyzed for traditional and novel immunohistochemical markers. In the paraganglioma group, there were 8 men and 14 women between the ages of 23 and 79 years (mean, 46 years). Their symptoms depended on the location of the tumor and included neck swelling and Horner syndrome for neck tumors, whereas abdominal and chest pain was present in tumors of the abdomen and mediastinum, respectively...

OBJECTIVE: Post-partum thyroiditis (PPT) is a common phenomenon in the general population. To date there have been few studies examining the incidence of PPT in women with hypothyroidism antedating pregnancy. This study aimed to assess the incidence and potential predictors of PPT in women with treated hypothyroidism antedating pregnancy. DESIGN: Retrospective cohort study. PATIENTS AND METHODS: We compiled a cohort of 97 women with previous hypothyroidism antedating pregnancy seen in the Endocrinology in Pregnancy clinic from 1999 to 2011, collecting data on thyroid function, antibodies and levothyroxine doses post-partum...

OBJECTIVE: The objective was to correlate the number, size and extent of the nodules as determined during the preoperative clinical examination of the thyroid gland, USG, intra-operative examination and histopathology. Also, FNAC (with or without USG guidance) and USG findings suggestive of malignancy were correlated with the final histopathology. SETTING: Tertiary referral centre PATIENTS: A retrospective chart review was done for 106 patients who underwent surgery for benign or malignant nodular thyroid disease in our center, between Jan 2004-Dec 2006...

CCDC6 was originally identified in chimeric genes caused by chromosomal translocation involving the RET proto-oncogene in some thryoid tumors mostly upon ionizing radiation exposure. Recognised as a pro-apoptotic phosphoprotein that negatively regulates CREB1-dependent transcription, CCDC6 is an ATM substrate that is responsive to genotoxic stress. Here we report that following genotoxic stress, loss or inactivation of CCDC6 in cancers that carry the CCDC6 fusion, accelerates the dephosphorylation of pH2AX S139, resulting in defective G2 arrest and premature mitotic entry...

Interleukin (IL)-18 is a cloned cytokine that was identified originally as a factor having potent interferon (IFN)-gamma-inducing activity on Kupffer cells. First, we analyzed IL-18 gene expression by reverse transcription-polymerase chain reaction (RT-PCR) in rat thyroid FRTL-5 cells and human thyroid tissue samples. The expression of IL-18 mRNA in FRTL-5 cells was enhanced by thryoid-stimulating hormone (TSH) in a dose-dependent manner. 8-Bromo-cyclic adenosine monophosphate (cAMP) also increased in IL-18 mRNA levels...

BACKGROUND: The study evaluates the incidence of both early and protracted post-thyroidectomy hypocalcemia over a 6-year period (1995-2000) in a series of 330 consecutive thryoid operations. The aim was to identify the profile of patients with the greatest risk of permanent parathyroid functional insufficiency and a suitable treatment protocol. METHODS: Having performed a statistical ana-lysis of all the variables, we divided the entire population of 330 patients into 4 groups based on the extent of demolition, the method of organotherapeutic replacement with L-Thyroxine and the (eco-radioguided) procedure used to identify the parathyroids: 59 patients undergoing subtotal thyroidectomy; 155 patients undergoing total thyroidectomy who commenced replacement organotherapy from postoperative day 15-30; 94 patients undergoing total thyroidectomy who commenced replacement organotherapy from postoperative day 1; 22 patients undergoing total thyroidectomy who underwent routine intraoperative parathyroid assay...

Two cases of multi-drug-resistant pulmonary tuberculosis with para-aminosalicylic acid (PAS)-induced hypothyroidism were reported. Case 1; a 73-year-old male, complaining of edema, was admitted to our hospital. He had been treated for his multi-drug-resistant pulmonary tuberculosis during the past 1 year with an antituberculous regimen consisting of ethambutol (EB), ethionamide (ETH) and PAS. A thyroid profile performed when he was admitted to our hospital showed several marked abnormalities: serum thyroid stimulating hormone (TSH) was elevated (69...

The aim of the study was to evaluate the possible interactions and/or modulations of the serotoninergic system on hormonal parameters and the reproductive axis in amenorrheic subjects. Hypogonadotropic, underweight, amenorrheic patients (n = 8) were studied before and during cyproheptadine clorhydrate administration (4 mg/day for 3 months). A pulsatility study (4 hours, sampling every 10 minutes) and a naloxone test were performed before and after 4 and 12 weeks of treatment. Plasma luteinizing hormone (LH), follicle-stimulating hormone (FSH), growth hormone (GH), estradiol, thryoid-stimulating hormone (TSH), free tri-iodothyronine (fT3), free thyroxine (fT4) and total tri-iodothyonine (total T3), insulin-like growth factor-I (IGF-I) concentrations were determined...

Thyroid lesions develop in most NOD.H-2h4 mice 6 weeks after they are given 0.05% NaI in drinking water. B cells are required for spontaneous autoimmune thyroiditis (SAT) development, and anti-thyroglobulin autoantibody levels correlate with SAT severity. Immunohistochemical staining of thyroids obtained 2-10 weeks after administration of NaI water suggested that CD4+ T cells initially infiltrated the thryoid, followed by CD8+ T cells and B cells. Intrathyroidal CD4+ T cells are more numerous than CD8+ T cells...

Previous evidence suggests the existence of a thyroid hormone-IGF axis in the liver and changes in hepatic insulin-like growth factor binding protein (IGFBP) expression in rats with altered thyroid status have been previously reported. The aim of this study was to check if the higher IGFBP-2 mRNA levels observed in liver of hypothyroid rats could be due to a direct effect of thyroid hormone on the IGFBP-2 gene. In our experiments, cultured hepatocytes isolated from normal and hypothyroid adult rats were used...

I D McDermott, G W Watters
Two cases of papillary thryoid carcinoma presenting as a cystic lateral neck mass are reported. This tumour characteristically presents in patients under 40-years-old and in the presence of an occult primary tumour may mimic a branchial cyst. In such cases simple aspiration of the cyst will produce a chocolate-brown serous fluid which excludes the diagnosis of a branchial cyst and is characteristic of papillary thyroid carcinoma. Cytological examination of the fluid has a high degree of sensitivity and specificity in the diagnosis of thyroid malignancy and should avoid delay in diagnosis and unnecessary surgical exploration prior to definitive treatment...

Analysis of the protein composition of the thyroid colloid was performed in 28 patients operated on for hyperthyroidism. Fifteen of the patients were treated before the operation with carbimazole combined with thyroxine and 13 were treated with propranolol alone. Colloid was collected by micropuncture of single follicles in peroperative thyroid biopsies. The protein composition was analysed by microgel electrophoresis and densitometry, both in the colloid samples and in the supernatant fraction of homogenates of microbiopsies from the thyroid specimens...

Observatios were made on the rough endoplasmic reticulum (RER) of the blood capillary endothelium, pericytes, and lymphatic endothelium in the course of studies of changes occurring in the thryoid gland during the development of thyroid hyperplasia. To induce the hyperplasia, Fischer rats were fed a goitrogen (thiouracil) an a low iodine diet for various time intervals from 3-100 days. Thyroid glands were fixed by perfusion with glutaryldehyde and embedded in Epon. A noticeable increase in the RER in the capillary endothelium was seen by 3 days...

Sprague-Dawley rats were sacrificed by decapitation at 5, 7, 12, 14, 22, 26, 32, and 40 days of age. Adult animals (175 to 225 g) were also studied. Serum-free thyroxine (FT4) concentrations rose rapidly between 5 and 12 days to levels similar to adult concentrations, whereas the percentage of FT4 was relatively high between 5 and 12 days before declining to adult values by 14 days. Serum-free triiodothyronine (FT3) concentrations rose progressively to attain peak concentrations at 26 days and subsequently declined to adult levels by 40 days...

A thyroid tissue culture system has been established in which follicular morphology can be preserved for at least 30 days. The system is highly dependent on whether or not the medium supporting the cells is changed during the culture period. The high levels of TSH (40 mU/ml) normally used in thyroid culture systems enhance follicular morphology but are not a prerequisite for differentiation. In the absence of medium changes follicular morphology improves for up to 20 days after initiation of the culture. Thereafter, the cells die unless the medium is changed...

In 1976, a spontaneous outbreak of thyroid adenocarcinoma occurred in a captive population of kelp bass, Paralabrax clathratus. Of 180 adult fish that died over 18 months, more than 100 had thyroid lesions. Nodules varied in size, consisted microscopically of diffusely expansive sheets of thryoid-like follicles, were present in the gill filaments, and projected from the floor of the pharynx into the buccal cavity. Although few of the morphologic criteria for malignancy existed in individual cells, the metastatic nature of the neoplasms was evidenced by the focal presence of follicles within the internal organs of many fish...
