Thyroid Stimulating Hormone (TSH) levels can be measured accurately down to a very low serum concentration with an immunoassay. When the serum TSH level is in the normal range, measuring the T3 and T4 levels is redundant. The objective of this study is to study the relation of TSH levels postoperatively in thyroid surgeries with the timing for thyroxin treatment as a supplemental and suppressive therapy. A prospective cohort study was done on 84 patients underwent thyroid operations in Al-Yarmouk Teaching Hospital from March 2010 through November 2012. Patients underwent different thyroid operations (lobectomy, subtotal thyroidectomy and total thyroidectomy) for different thyroid pathology. Later, they were followed up by TSH assay in periods of 2, 4, 6 and 12 months postoperatively. Variables were compared by using the analysis of variance, ANOVA test. P – values equal or less than 0.05 and 0.01 were considered to be statistically significant and highly significant, respectively. The mean age of patients was 43.30 ± 10.19 years. The females made the vast majority of study sample (85.7%). Patients were divided into six groups: simple colloid goiters (17 patients), multinodular goiters (32 patients), solitary thyroid nodules (11 patients), Hashimoto’s thyroiditis (8 patients), Graves’ disease (8 patients) and papillary and follicular carcinomas (8 patients). The study revealed that all patients with malignant thyroid nodules (i.e. those with total thyroidectomies) and the vast majority of patients with Hashimoto’s thyroiditis were in definite need for thyroxin treatment post-operatively. Other patients were variable in their need and timing of treatment according to the histopathological results and the type of operations. In conclusion; measurement of TSH level postoperatively is a good indicator for need of thyroxin treatment and for dose adjustment with the help of pathological results and the type of surgery.

Background: Thyroid cancer is the most common endocrine malignancy and its incidence continues to rise. Thyroid carcinoma in most cases presents clinically as a solitary nodule or as a dominant nodule within a multinodular thyroid gland. There are a number of well-established of predictors of malignancy in thyroid nodules. More recently studies have suggested that higher concentration of TSH, even within the normal range are associated with subsequent diagnosis of thyroid cancer in patients with thyroid nodules and even higher serum TSH levels have been found associated with advanced stages of thyroid cancer. Objectives were to determine the association between serum thyroid stimulating hormone (TSH) concentration and thyroid cancer and to estimate serum TSH levels in different stages of thyroid malignancy.Methods: A hospital based observational study was conducted in a tertiary care hospital for a period of 2 year. 120 patients presenting with thyroid nodule without an overt thyroid dysfunction during the study period were included in the study. Chi-square was used as test of significance. Independent t test was the test of significance for quantitative data between two groups.Results: In the study majority of thyroid cancer patients (106 out of 120) had serum TSH concentrations ranging 1.71mIU/L-5.5mIU/L i.e. within normal range but towards higher range. Mean serum TSH concentrations was significantly high in advanced stages of carcinoma. Mean Serum TSH was high in Stage III and Stage IV (5.17±1.36mIU/l) compared to stage I and II (4.03±1.87mIU/l).Conclusions: The study concludes that TSH levels were in the Upper reference range in majority of thyroid malignancies and high levels of serum TSH concentrations associated with advanced stage of thyroid cancer.

SUMMARY The effect of methallibure (ICI 33,828), a non-steroidal pituitary inhibitor, on serum and pituitary thyroid-stimulating hormone (TSH) levels has been investigated. A biphasic action of the drug on serum TSH levels was observed, the greatest falls occurring with the lowest doses (2mg/day). Increasing dose and period of administration induced progressive decreases in pituitary TSH content. These results are interpreted in terms of three actions on the thyroid—pituitary system: (1) inhibition of the release of TSH from the pituitary, (2) inhibition of TSH synthesis evident only at higher doses, and (3) a thyroid-blocking action, which is also only observed at the higher dose levels, with consequent pituitary stimulation via the thyroid—pituitary feedback mechanism. Effects upon body weight and weight of endocrine organs are reported, that upon the seminal vesicles being the most marked.

AbstractAssociation of Kocher-Debré-Semelaigne syndrome–a myopathy of hypothyroidism in childhood characterized by muscular hypertrophy, with rhabdomyolysis is very rare. We present a case of Kocher-Debré-Semelaigne syndrome with rhabdomyolysis secondary to Hashimoto’s thyroiditis. He had muscular symptoms simulating poly/dermatomyositis, massively elevated creatine kinase (CK) levels and high creatinine levels. All of the findings reversed on treatment of hypothyroidism. The response to the therapy strongly suggested that Kocher-Debré-Semelaigne (KDS) syndrome was the underlying etiology. Serum thyroid- stimulating hormone levels should be routinely determined in all patients with muscular symptoms and/or elevation of CK and creatinine, keeping KDS syndrome in mind.

Abstract. A 74 year old woman was found to have elevated serum thyroid-stimulating hormone (TSH) levels and elevated serum thyroid hormone levels, with clinical euthyroidism. There was no evidence of a pituitary tumour. TSH levels increased substantially during methimazole therapy. Administration of dexamethasone was followed by a prompt fall in serum TSH levels. Triiodothyronine (T3) was administered over a period of 20 days in doses from 25 μg to as much as 100 μg daily causing a rise in serum T3 above 700 ng/100 ml, a decline of T4 and a blunting of the response to thyrotrophinreleasing hormone (TRH), with normal metabolic responses (pulse rate, photomotogram, cholesterol). These results suggest that the patient's disorder is due to partial target organ resistance to thyroid hormones.

An elevated serum level of neopterin indicates the activation of the cellular immune system. Aim: The objective was to find a correlation in autoimmune thyroid patients between neopterin levels and the clinical stage of the disease and to examine whether neopterin can predict the relapse of the disease. Methods: Serum neopterin, thyroid stimulating hormone, free thyroxine, free triiodothyronine, anti-thyroglobulin and anti-thyroid peroxidase antibody levels were determined in 137 patients with Graves’ disease (in different stages), 25 with Hashimoto’s thyroiditis and 14 with toxic adenoma. Results: The neopterin levels were significantly higher in patients with Graves’ disease (hyper-, eu-, hypothyroidism and relapsed hyperthyroidism) and Hashimoto’s thyroiditis. Positive correlation was found between neopterin and anti-thyroglobulin and anti-tyhroid peroxidase antibody levels, but no correlation was detected between neopterin levels and thyroid hormones, thyroid stimulating hormone values and antibodies against thyroid stimulating hormone receptors. Conclusions: Higher level of serum neopterin reflects an underlying autoimmune process, and does not correlate with changes in thyroid hormone levels. Determination of neopterin level can be an important indicator in the exacerbation of autoimmune processes. Orv. Hetil., 2012, 153, 1127–1131.

Background: Thyroid neoplasm includes both benign and malignant tumors arising in the thyroid gland. Although thyroid cancer accounts for less than 1% of all cancers, the challenge to clinicians is to identify the minority of thyroid nodules that harbor malignancy. There are a number of well-established predictors of malignancy in thyroid nodules. More recently a few studies have suggested that higher concentration of thyroid stimulating hormone (TSH), even within the normal range are associated with subsequent diagnosis of thyroid cancer in patients with thyroid nodules and even higher serum TSH levels have been found associated with advanced stages of thyroid cancer. Methods: A prospective study was conducted on 220 cases without overt thyroid dysfunction attending Department of general surgery, Pushpagiri institute of medical science, Thiruvalla.  Results: In our study incidence of malignancy of thyroid carcinoma was highest in patients with serum TSH concentrations, in range of 3.5 mIU/l-5.25 mIU/l, 55 patients out of 220 patients. Individually, incidence of papillary carcinoma (PC) (36/55 patients), follicular carcinoma (FC) (17/55 patients) and Hurthle cell carcinoma (HCC) (2/55 patients) were more in patients with higher TSH. So, from the study it can be clearly state that elevated TSH can be used as an independent predictor of thyroid malignancy. Higher TSH values are associated with papillary thyroid carcinoma.Conclusions: An elevated TSH can be used as an independent predictor of thyroid malignancy, especially for anticipating a probability of papillary carcinoma of thyroid.
