Introduction: Radioiodine (131-I) treatment for benign thyroid disease has a 70 year history. Among the radioactive isotopes, (131-I) can be used successfully. The intention of radioiodine treatment is primarily to induce a euthyroid or hypothyroid state, but in the case of large multinodular goitres, shrinkage represents a secondary aim of therapy. The optimal method for determining iodine-131 treatment doses for Toxic Thyroid nodule is unknown, and techniques have varied fro...

Background: Graves’ disease (GD) typically manifests as an autoimmune hyperfunction of both thyroid lobes. Less than 10 cases of unilateral GD have been described, and the pathophysiology of unilateral GD remains unknown. Co-existence of malignancy has never been reported. We report a case of GD of the left lobe with simultaneous discovery of a papillary carcinoma within the hyperfunctioning lobe.Case description: A 49-year-old patient of Middle-Eas...

Background: Data regarding the effect of gender and age on medullary thyroid cancer (MTC) presentation and prognosis is limited. Although older age and male sex were found to correlate with poorer prognosis in some studies, this correlation may reflect differences in MTC presentation between sex and age groups, or a mixture of hereditary and sporadic MTC forms.Objective: To evaluate the impact of age and sex on the presentation and outcomes of MTC.<p...

Background: The incidence of thyroid cancer in South Korea has increased rapidly. Increase in medical surveillance and access to health care services have enhanced the detection of asymptomatic tumors. We investigated the differences of tumor characteristics between South Korean patients and Northern Italian patients subject to different healthcare systems.Methods: The demographic, histopathologic and management features of thyroid cancer operated in two...

Current UK guidelines for thyroid nodules advise a thyroid ultrasound (ThyUSS) with U-Classification with or without Fine Needle Aspiration (FNA) with Thy-Classification to determine malignancy risk. We report four cases where thyroid carcinoma was diagnosed histologically following reassuring cytology and radiological examination. This is a case of 28-year-old female who presented with neck swelling. ThyUSS showed an enlarged left thyroid with cystic and solid components; FNA...

Background: Hypothalamic KNDy neurons have recently been identified as key regulators of reproductive function by releasing three neuropeptides namely kisspeptin, neurokinin B (NKB) and dynorphin. Animal studies show they interact to control pulsatile GnRH release, which is vital for fertility. In animals, kisspeptin stimulates, NKB modulates and the opioid dynorphin inhibits GnRH pulsatility. However, the interaction of these peptides has never been studied in humans. To inve...

Background: Oral semaglutide GLP1 receptor agonist is coformulated for better absorption compared to prior injectable semaglutide. Phase 2 open label, dose escalation randomized clinical trials of semaglutide and liraglutide investigating the dose-response relationship between the two. DPP-4 inhibitor produces a smaller glycemic reduction and minimal weight reduction through effect of endogenous GLP-1 receptor activity, while GLP-1RAs yield greater efficacy related to the phar...

Recent years have seen a dramatic rise in interest in preserving fertility in women facing treatment for cancer and other serious diseases, and fertility preservation is rapidly becoming a mainstream part of reproductive medicine. This approach, however, serves to remove oocytes or ovarian tissue before cancer treatment, rather than directly protecting the ovary itself. Some chemotherapies and radiotherapy have well known adverse effects on follicle number, although the detail...

Introduction: Patients with acromegaly have an increased mortality, mainly due to cardiovascular and respiratory diseases. Sleep apnea is related to hypertension, stroke and cardiovascular diseases and is reported to occur in 11–30% of acromegaly patients, according to retrospective studies based on diagnostic ICD-codes. However, in smaller prospective studies sleep apnea is found in about 70% of patients with active acromegaly and 40% after biochemical control. This diff...

Introduction: Maternal thyroid hormone during early pregnancy is important for proper fetal growth and development. Thyroid hormone receptors are widely expressed in placental tissue. Interestingly, thyroid dysfunction and suboptimal placental function have both been associated with pregnancy complications including preeclampsia, premature delivery and fetal growth restriction. First, we studied the association of the maternal thyroid and placental function and second, we inve...
