Introduction: Neuroendocrine neoplasms (NENs) are a heterogeneous group of tumors arising from neuroendocrine cells in the endocrine and central nervous system, the natural history of which remains inadequately understood. Large epidemiological studies are gradually emerging from different countries worldwide, which contribute to the establishment of a spherical view about these tumors. The purpose of this study is to evaluate the epidemiological, clinical and pathological cha...

Background: We previously showed that menopausal hormone therapy (MHT) favorably affects both bone density and microarchitecture with persistent benefit after its withdrawal (1). Looking for indirect factors contributing to bone effects, we investigated the relation between MHT and changes on fat and lean (muscular) tissue. Existing results on MHT and body composition are conflicting and large cohort studies are lacking.Material and methods: The OsteoLau...

Objectives: • PCOS is defined by the presence of hyperandrogenism (clinical and/or biochemical), ovarian dysfunction (oligo-anovulation and/or polycystic ovaries), and the exclusion of related disorders.• Women are exposed to increased risk for cardiovascular disease, hypertension, type 2 diabetes mellitus and other metabolic complications• Cardiovascular disease (CVD) is one of the most common cause of mortality wor...

Background: Klinefelter syndrome (KFS) is the most common chromosomal aberration in men, characterized by an extra-X chromosome (47, XXY). Besides the well-known reproductive defects, KFS is characterized by a 4-fold increase in metabolic syndrome, cardiovascular morbidity and mortality. The exact cause of this constellation remains unclear.Methods: Data from non-mosaic KFS adults and adolescents, evaluated in the endocrine unit of Lausanne University Ho...

Objective: 17-alpha-hydroxyprogesterone caproate therapy during pregnancy has been associated with insulin resistance. The aim of this study was to highlight any possible association of 17OHP with insulin resistance in women with PCOS.Design: Forty-five women with PCOS underwent 75 g OGTT test and short Synachten test with sampling of stimulated 17OHP. Women were divided into two subgroups according to basal 17OHP cut-off level of 0.8 ng/ml.<p class=...

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...

Introduction: 21-hydroxylase deficiency (21-OHD) is a common inherited disorder accounting for 90–95% of congenital adrenal hyperplasia (CAH) cases. Some cases may be diagnosed in adulthood after the incidental discovery of adrenal masses on computerized tomography (CT).Case report: A 59-year-old male was investigated for incidentally discovered bilateral adrenal masses in an abdomen CT scan, measuring 5 cm on the right and 8 cm on the left adrenal....

Objective: Quality of life is currently considered a major factor in the assessment of disease outcome. The aim was to assess quality of life in acromegaly and the effect of somatostatin analogues on it.Design: This study included 101 patients with acromegaly, mean age 59.51±1.35 years (mean ± S.E.M.), with a disease duration of 12.88±0.96 years. All subjects completed the Acromegaly Quality of Life Questionnaire (AcroQoL) w...

Background: 25 hydroxy vitamin D (25(OH)D) vitamin levels are positively associated with bone mineral density and season, time of day and sun exposure duration influence its synthesis. Variations in daylight throughout the year and zenith angle, depending on the latitude of residence, influence u.v. solar radiation which is closely related to serum 25(OH)D levels. The aim of this study was to investigate the degree of seasonal variation of 25(OH)D serum levels in a population-...

Background and objectives: Medullary thyroid carcinoma (MTC) originates from thyroid C-cells and is a calcitonin (CT) secreting tumour with aggressive behaviour. Surgery is recommended in all patients with basal or calcium-stimulated CT values of 100 pg/ml or higher due to the high probability of MTC. The objective of this study was to investigate the utility of calcium stimulation test for CT in order to distinguish MTC from C-cell Hyperplasia (CCH) preoperatively and to exam...
