Background: Several resting state networks have been described in literature. Today, it is still unclear whether these networks are stable or can be influenced by sex hormones. Transgender persons offer a unique opportunity to study these hormonal influences.Objective: To examine the effects of cross-sex hormone treatment in transgender persons on two resting state networks involved in cognition and emotion, the default mode network and executive network...

Introduction: Hyperthyroidism and thyrotoxicosis can have multiple etiologies, varying from the most frequent described in clinical practice (Graves disease, toxic nodular goiter, thyroiditis) to very rare causes such as anaplastic thyroid cancer, thyroid lymphoma, amyloidosis or even secondary malignancy of the thyroid gland.Case report: A 53 year old man presented to our department for progressive goiter enlargement in the last two months which was acc...

Primary vaginal malignancy is uncommon, accounting for about 2% of all gynecological tract cancers, with small-cell neuroendocrine carcinoma of the vagina being exceptionally rare and aggressive. They display similar histological and immunohistochemical features to small-cell carcinomas of different origin. Few cases are reported in the literature so far and therefore, there is no current treatment protocol consensus. We report the case of a 34-year-old nulliparous patient, wh...

Introduction: Cushing disease is the most common cause of endogenous hypercortisolemia and most frequently is caused by microadenomas, but rarely, only in 10% to 20% of cases, the adenomas are large enough to produce mass effect.1Case report: We present the case of a 63 years old female patient, diagnosed in 2007 with a 22/18 mm non-secreting pituitary adenoma and panhypopituitarism. She undergone transsphenoidal surgery twice, followed by gam...

Background, aims: Acromegaly is caused by excessive growth hormone (GH) secretion, usually by a pituitary adenoma. Surgical removal of the GH-producing adenoma is the most effective treatment. Drug treatment is second-line option. Earlier work suggested Soluble (s)Klotho levels to be a supplementary biomarker to IGF-1. We tested whether IGF-1 and sKlotho serum levels show a concomitant reduction under medical treatment. If yes, is the extent of reduction in serum IGF-1 and sKl...

Objective: The aim of this retrospective study is to evaluate the bone status in patients receiving oncological treatment, like radiation, chemotherapy, adjunctive therapies, and surgery.Material and methods: Medical records of 102 womens (mean age 59.12 yrs) with breast cancer history reffered for endocrine evaluation were retrospectivelly analysed. Demographic data, bone densitometry parameters, prevalent fractures and antineoplastic treatments history...

Feral cat numbers in the UK are thought to number around one million and the Dogs Trust estimates it dealt with just over 110 000 stray and abandoned dogs in 2013. This scenario is common across the world and in the developing world in particular the control of feral populations is an ongoing challenge as well as a huge welfare issue. The only options currently available are expensive surgical neutering, or euthanasia of otherwise healthy animals. There is an urgent need to de...

Context: Primary aldosteronism (PA) represents the most frequent cause of a curable secondary arterial hypertension. Conflicting data have been published regarding the effect of aldosterone excess on glucose and lipid metabolism.Objective: Our aim was to analyze insulin sensitivity and beta cell function in a cohort of PA patients. Prospective follow-up investigations were performed in a subgroup of patients before and after adrenalectomy to assess the m...

Mass spectrometry based clinical metabolomics needs standardization of analytical assays to improve future inter-laboratory comparability and to become a successful new and established technology in clinical routine laboratories such as mass spectrometry based therapeutic drug monitoring (TDM) over the past 10 years. Steroid hormones are one of the most interesting endogenous metabolite class in clinical metabolomics today. Standardized determination of concentrations of stero...

Background: Resistin was originally proposed in animal models as a link between obesity and insulin resistance, but later studies in humans have shown a divergent role. Yet, resistin seems to be involved in the development of atherosclerosis in humans by promoting the formation of foam cells; further, its expression is induced by oxidized low-density lipoproteins (LDL) in human macrophages.Methods: We assessed the relationships between resistin and marke...
