Cervical hemorrhage due to non-traumatic, spontaneous rupture of the thyroid artery is rare, which usually results from arterial abnormalities or parathyroid or thyroid disorders. This report describes a 72-year-old woman who presented with a sore throat and slight neck swelling. Computed tomography (CT) revealed a large hematoma in the neck and mediastinum, due to extravasation from the major branch of the left superior thyroid artery. A follow-up CT the next day demonstrated that the extravasation had resolved...

Non-alcoholic fatty liver disease (NAFLD) is the most common liver disorder in industrialized countries and is associated with increased risk of cardiovascular, hepatic and metabolic diseases. Molecular mechanisms on the root of the disrupted lipid homeostasis in NAFLD and potential therapeutic strategies can benefit of in vivo and in vitro experimental models of fatty liver. Here, we describe the high fat diet (HFD)-fed rat in vivo model, and two in vitro models, the primary cultured rat fatty hepatocytes or the FaO rat hepatoma fatty cells, mimicking human NAFLD...

Thyroid emergencies are major life-threatening endocrine conditions associated with life-threatening disorders resulting from either severe deficiency or excess of thyroid hormones. Deficiency of thyroid hormones may present as myxedema coma whereas excessive hormone production can present as life threatening thyrotoxic storm. The diagnosis of both requires a high index of clinical suspicion. Thyroid storm, in spite of accurate diagnosis, continues to have high fatality, whereas myxedema management has markedly improved with advancement in intensive care facility...

OBJECTIVE: Hypothyroidism is defined as an underactive thyroid gland and one of the reasons for inadequate stimulation of thyroid is dysfunction of the hormone regulating brain centers. Olfaction disorders have been considered as a problem in hypothyroidism. It has been hypothesised that olfaction disorders reduce olfactory stimulation and diminished olfactory stimulus may trigger hypothyroidism. In this study an examination was made of the thyroid hormone levels, histological features of thyroid glands and vagal nerve network degradation in an experimental animal model of olfactory bulbectomy (OBX)...

BACKGROUND: Our studies over recent years have focused on some new ideas concerning the pathogenesis for the orbital reaction that characterizes Graves' ophthalmopathy namely, that there are antigens expressed by thyroid tissue and orbital tissue where they are targeted by autoantibodies and/or sensitized T cells, leading to orbital inflammation. While this has been well studied for the thyroid stimulating hormone-receptor, the possible role of another major thyroid antigen, Thyroglobulin (TG), has been largely ignored...

BACKGROUND: Autoimmune thyroiditis (AT) is one of the most common endocrine disorders affecting a significant percent of the population, especially women. It may have serious and long-lasting consequences. The etiology of AT is multifactorial and it arises from an interplas between environmental and genetic factors. Tendencies in AT prevalence and incidence are unclear. In Poland there are no national registers covering the data on AT prevalence. OBJECTIVES: The aim of the investigation was to assess changes in diagnosing AT in the largest chain of outpatient medical centers in Poland...

Dental radiology uses X-ray technology to diagnose and design treatment of various clinical problems related to the oral cavity and surrounding tissues. As technology quickly evolves, there are numerous X-ray modalities using different tools in the attempt to best image and treat efficiently these diseases, disorders or other related clinical conditions. The reported numbers of dental X-rays, the fact that these may be under-reported in many countries and because dental X-rays are performed more on younger individuals, whose teeth and dentition are still developing, calls for increased need on radiation protection...

Hyperthyroidism causes impaired glucose tolerance, insulin resistance (IR) and insulin secretion. However, the glucose variability affected by thyroid dysfunction remains unclear. Glucose variability was assessed by continuous glucose monitoring (CGM) in a non-diabetic patient with Graves' disease (GD), to the best of our knowledge, for the first time. A 28-year-old man with GD, who had been taking methimazole for 4 years, was treated with radioiodine on August 17th 2016. Although the patient exhibited normal glycated hemoglobin (HbA1c; 5...

Endocrine disruptors (EDs), chemical substances widely used in industry and ubiquitously distributed in the environment, are able to interfere with the synthesis, release, transport, metabolism, receptor binding, action, or elimination of endogenous hormones. EDs affect homeostasis mainly by acting on nuclear and nonnuclear steroid receptors but also on serotonin, dopamine, norepinephrine and orphan receptors in addition to thyroid hormone receptors. Tributyltin (TBT), an ED widely used as a pesticide and biocide in antifouling paints, has well-documented actions that include inhibiting aromatase and affecting the nuclear receptors PPARγ and RXR...

BACKGROUND: Fetal goitrous hypothyroidism is mainly caused by maternal treatment of Graves' disease. Fetal goiter sometimes compresses the trachea and esophagus and may cause polyhydramnios, preterm labor, complications of labor and delivery, and neonatal respiratory disorder. CASE PRESENTATION: We report a case of fetal goitrous hypothyroidism in which the mother had Graves' disease, which was treated with propylthiouracil. Intra-amniotic levothyroxine (L-T4) administration was performed, and the fetal goiter decreased in size...

Microscopic colitis (MC) is an inflammatory condition of the large bowel that is associated with chronic, nonbloody diarrhea. Colonoscopy usually demonstrates normal mucosa, while tissue biopsy reveals intraepithelial lymphocytes or a subepithelial collagen band. Although no specific antibody has been discovered, MC is associated with several autoimmune disorders such as celiac disease, Hashimoto's thyroiditis, and rheumatoid arthritis. There are only a small number of case reports documenting possible hereditary MC cases, but up to 12% of patients with MC have a family history of inflammatory bowel disease...

BACKGROUND: Composite pheochromocytoma/paragangliomas are very rare tumors composed of ordinary pheochromocytoma paragangliomas associated with neurogenic tumors. Several hereditary susceptibility disorders are known to be associated with pheochromocytoma/paragangliomas such as multiple endocrine neoplasia type 2 (2A or B). To the best of our knowledge, only four cases of composite pheochromocytoma/paragangliomas associated with multiple endocrine neoplasia type 2 have been reported. CASE PRESENTATION: A 40-year-old Arabic woman presented with headache, palpitations, paroxysmal hypertension, and weight loss, which she had had for the last 3 years...

PURPOSE OF REVIEW: The current review summarizes previous reports on laryngopharyngeal symptoms associated with thyroid disease. This review also includes pharyngolaryngeal symptoms caused by thyroidectomy. However, we focus on pharyngolaryngeal symptoms following uncomplicated thyroidectomy, as this is an important issue in the fields of otolaryngology. RECENT FINDINGS: An enlarged thyroid gland, as in thyroiditis, multinodular goiter, or large nodules, can cause compressive symptoms...

PURPOSE: Previous animal studies have reported that acute anticholinesterase pesticide (organophosphate and carbamate) poisoning may affect thyroid hormones. However, there is no human study investigating the association between hypothyroidism and anticholinesterase pesticide poisoning, and therefore, we conducted a retrospective nationwide population-based cohort study to delineate this issue. METHODS: We identified 10,372 anticholinesterase pesticide poisoning subjects and matched 31,116 non-anticholinesterase pesticide poisoning subjects between 2003 and 2012 from the Nationwide Poisoning Database and the Longitudinal Health Insurance Database 2000, respectively, in a 1:3 ratio by index date, age, and sex for this study...

PURPOSE: PTEN and KLLN are two tumor suppressor genes located in 10q23, share a bidirectional promoter and have roles in carcinogenesis. Formerly, the role of PTEN mutations and KLLN epimutations were identified in incidence of thyroid lesions in individuals with Cowden syndrome, a rare autosomal dominant inherited disorder. This study is the first of its type to assess PTEN and KLLN circulating levels in patients with sporadic papillary thyroid carcinoma (PTC) and compare to patients with multinodular goiter (MNG) and healthy individuals...

Cardiovascular disease (CVD) is the leading cause of morbidity and mortality in patients with end-stage renal disease. Chronic kidney disease (CKD)-associated cardiovascular mortality is more prevalent in those with diastolic heart failure and is an early predictor, while increased left ventricular mass (LVM) is a strong independent risk factor. Hypovitaminosis D is extensively being studied as a nontraditional risk factor for CVD. The aim of the present study is to look at the association of Vitamin D and other parameters of mineral bone disorder (MBD) with diastolic dysfunction and LVM in nondiabetic young adult patients with CKD...
