Background: Dysfunctional adipose tissue in obesity is known to contribute to metabolic diseases, including type 2 diabetes mellitus (T2DM). This may be due to increased gut-derived endotoxemia (LPS) reducing brown adipose tissue (BAT) activity and altering mitochondrial function. However, the effect of LPS on BAT activity in 3D culture models has not been studied, despite giving a better representation of in-vivo tissue. Therefore, this study investigated the effects of LPS o...

Introduction: Primary thyroid lymphoma (PTL) is a rare cause of malignancy, accounting for <5% of thyroid malignancies and < 2% of extra-nodal lymphomas. Most thyroid lymphomas are non-Hodgkin’s lymphomas of B-cell origin. Patients with Hashimoto’s thyroiditis are at greater risk for developing PTL. Early diagnosis is important as treatment and prognosis of PTL depend upon the histology and stage of the tumour at diagnosis. We report a rare case of primary th...

Introduction: Primary thyroid lymphoma (PTL) is a rare cause of malignancy, accounting for <5% of thyroid malignancies and < 2% of extra-nodal lymphomas. Most thyroid lymphomas are non-Hodgkin’s lymphomas of B-cell origin. Patients with Hashimoto’s thyroiditis are at greater risk for developing PTL. We report a rare case of primary thyroid lymphoma in a patient presenting with a rapidly enlarging thyroid goitre highly suspicious of anaplastic thyroid carcinom...

Background and aims: Electrolyte imbalance is common among hospital inpatients, reflecting severity of underlying illness, but also independently contributing to excess morbidity and mortality. However, studies have largely been retrospective, with incomplete data capture. We prospectively evaluated the prevalence of major Na and Ca disorders among inpatients at the Newcastle-upon-Tyne Hospitals.Method: With approval of the Information Guardian, we used ...

Introduction: Accumulating evidence suggests that one of the most significant contributors to endothelial dysfunction is increased oxidative stress. Excessive reactive oxygen species (ROS) generation can have injurious effects within the vasculature including elevated expression of adhesion molecules, stimulation of vascular smooth muscle cell proliferation, and promotion of endothelial cell apoptosis; events which culminate in the formation and progression of atherosclerotic ...

Background: Insulin dose requirements are higher during puberty and in overweight/obese individuals with type 1 diabetes mellitus (T1DM) due to insulin resistance. Through meta-analysis metformin has been shown to be beneficial as adjunctive therapy in T1DM adults independent of BMI. The large volumes of insulin required to administer higher insulin doses in insulin-resistant individuals have adverse effects on insulin absorption. Insulin degludec (Tresiba) U200 preparation al...

Background: Generally Endocrinologists strive to diagnose conditions biochemically prior to radiological investigation. Pituitary incidentalomas are observed in 10% of pituitary MRIs and together with stress induced hyperprolactinaemia, 10–20% of patients receive dopamine agonists (DAs) without a definite diagnosis. Menstrual imbalance is a common symptom of hyperprolactinaemia which can have multiple origins (e.g. hypothalamic, pituitary or ovarian). DAs have side effect...

Silent corticoptroph adenomas (SCA) are pituitary tumours positive on immunohistochemical staining for ACTH but without clinical evidence of hypercortisolism. They account for 1.1–6% of surgically removed pituitary adenomas. Most tumours are macroadenomas with suprasellar extension present in 87–100% of the cases. They present with mass effects and this is in contrast to Cushing’s disease, which is mostly attributed to microadenomas. Reports suggest that these t...

Background: The use of intra-articular (IA) glucocorticoids for reducing pain and inflammation in patients with osteoarthritis, rheumatoid arthritis, and other inflammatory arthropathies is widespread among primary care physicians, specialists and non-specialists in the United States. Injectable glucocorticoids have anti-inflammatory and analgesic properties which can be effective in improving clinical parameters such as pain, range of motion, and quality of life. After inject...

Background: Ectopic pituitary adenomas are defined by the presence of adenomatous pituitary tissue outside the sella and distinctly separate from the pituitary gland. Ectopic ACTH-secreting pituitary adenomas (EAPAs) are a rare cause of Cushing’s syndrome. Detecting these radiologically can prove difficult, in part, due to their typically small size and unpredictable anatomical location.Aim: We reviewed the current literature on all previously repor...
