Background: Preexisting chronic autoimmune thyroiditis is the only known risk factor for thyroid lymphomas, a rare variant of thyroid cancer. Here, we describe a male patient with previously undiagnosed Hashimoto’s thyroiditis who presented with severe airway compromise due to a thyroid lymphoma.Case report: 60 y/o, former smoker, presented with 2 month neck fullness and dyspnea that awakened him throughout the night due to malpositioning of his nec...

Hypopituitarism is a potential complication of trans-sphenoidal adenomectomy (TSA). Prediction of pituitary function (PF) recovery would inform hormonal replacement strategies. However, the frequency of re-testing of PF is variable across centres. The aim of this study was to determine rates, time and predictors of 6-weeks (6 w) recovery of hypothalamo-pituitary adrenal (HPA) and gonadal function after TSA.Methods: We performed a single-centre, retrospec...

Introduction: Familial Partial Lipodystrophies (FPLD) are rare genetic disorders characterized by marked loss of subcutaneous fat from the extremities with variable fat loss from the face and trunk. Patients with FPLD develop metabolic abnormalities including hypertriglyceridemia, insulin resistance, and diabetes mellitus, which are difficult to manage with conventional therapies including fibrates, statins and insulin. The BROADEN study evaluated the efficacy a...

Introduction: Familial Partial Lipodystrophy (FPLD) is a rare genetic disorder characterized by marked loss of subcutaneous adipose tissue from the extremities and is associated with a variety of metabolic abnormalities. While phenotypic elements of the disorder can vary across genotypes, symptomatic presentation, disease severity, and onset can also vary among individuals with the same disease-causing variant, or even among family members. Due to this variabili...

Purpose: Although quality of life (QoL) is improved in patients with acromegaly after disease control, QoL correlates only weakly with traditional biomarkers. Our objective is to investigate a potential relation between the new serum biomarker soluble Klotho (sKlotho), GH and insulin-like growth factor 1 (IGF-1) levels and QoL.Methods: In this prospective cohort study, we investigated 54 acromegaly patients biochemically well-controlled on combination tr...

Habitual post-prandial absorption of saturated fatty acids (SFAs) increases systemic atherogenic lipoproteins and a pro-inflammatory response, a condition exacerbated by obesity, insulin resistance (IR) and type 2 diabetes mellitus (T2DM). Also, gut derived bacteria (endotoxin) is absorbed coupled to damaging lipoproteins as it crosses the mucosa, which could directly impact on adipose tissue, as our previous studies suggest. The current studies addressed whether a SFA rich me...

Introduction: Various imaging modalities are used in the preoperative localization of insulinoma. CT is the modality that is in widespread use. Endoscopic ultrasound (EUS) allows the transducer to be placed in close proximity to the pancreas, thereby yielding images of higher quality, leading to accurate localization. An accurate preoperative localization results in a minimal invasive surgery and less occurrence of residual tumors, translating into a better clinical outcome. O...

Aims: Second-generation antipsychotics (SGA), especially clozapine and olanzapine, are associated with increased metabolic risk. Plasma adiponectin levels, vary in schizophrenia patients as in the general population according to gender, adiposity and metabolic syndrome (MetS).Here, we investigated whether different SGAs differentially influence plasma adiponectin levels independent of body mass index (BMI) and MetS status.Methods: ...

The 16-kDa N-terminal fragment of human prolactin (16K hPRL) is a potent angiostatic factor described to prevent tumor growth in mouse models. Using microarray experiments, we have dissected how the endothelial-cell genome responds to 16K hPRL treatment. Of the 23.000 transcripts present on the chips, 210 are regulated by 16K hPRL. Bio-informatic analysis and experiments performed on endothelial cells with various chemical inhibitors clearly suggest that NF-κB is crucial ...

Orbital fat (OF) represents a highly specialised adipose tissue depot that occupies a confined space behind the eyeball known as the orbit. OF fills most of the orbital cavity providing support to the delicate structures that link the eye to the brain, and protects against sight-threatening mechanical and inflammatory trauma. Subcutaneous (SC) and omental (OM) adipose tissues are highly active endocrine organs, regulated in part by glucocorticoids (GCs). The pre-receptor regul...
