Introduction: Monomorphic epitheliotropic intestinal T-cell lymphoma (MEITL), formerly known as type II enteropathy-associated T-cell lymphoma, is a rare and aggressive subtype of lymphoma of the gastrointestinal track typically noted in Asian or Hispanic populations. Adrenal involvement as part of MEITL is extremely rare. Herein we present a patient of Greek origin with MEITL and bilateral adrenal metastases.Case Presentation: A 74-year-old man presente...

Multiple endocrine neoplasia type 1(MEN1) is a hereditary condition caused by mutations in the MEN1 gene, which encodes menin protein. The syndrome predisposes to the development of tumors in both endocrine and non-endocrine systems. In patients with MEN1, pituitary adenomas (PA) occur in approximately 40% of all cases. If patient has MEN1 phenotype with no mutations in MEN1 gene, the condition is regarded as a phenocopy. The reason of several endocrine MEN1-...

Introduction: Prolactinomas are the commonest type of secretory pituitary tumours. In current practice, dopamine agonists (DA) remain the mainstay treatment. However, treating physicians are increasingly aware of DA-associated impulse control disorders (ICD) in their patients. We describe 4 individuals with prolactinomas, who either developed ICD on DA or deemed at ‘high risk’, successfully managed surgically with preservation of pituitary function. All decisions for...

Case history : A 44-year-old female presented with 6-week history of gradual deterioration in her left vision associated with eye pain. She saw an ophthalmologist who noted that she had reduced visual acuity (6/24) and colour vision (Ishihara colour vision score 3/15) in her left eye with left relative afferent pupillary defect (RAPD). It was thought that she may have a left retrobulbar neuritis so she was advised to attend A&E for an urgent neurology assessment. On examin...

Intracellular nicotinamide phosphoribosyltransferase (NAMPT) is the rate-limiting enzyme in the NAD salvage pathway. Abnormally elevated NAMPT can promote autoimmune and inflammatory processes. Many of these processes are key to type 1 diabetes (T1D) pathogenesis. Whilst NAMPT has been examined in other inflammatory diseases, the role of NAMPT in T1D remains unclear. To investigate the role of NAMPT in T1D, we used small molecule NAMPT modulators to determine the role of abnor...

Introduction: Over half of postmenopausal women suffer symptoms which can sometimes be non-responsive to hormone replacement therapy (HRT). Testosterone is implicated in regulating urogenital and sexual function in women. However, using testosterone therapy in postmenopausal women remains highly controversial, principally due to the lack of syndromic relationship between serum testosterone levels and onset of sexual dysfunction during menopause. Clinical practice is therefore ...

Objective: Recent evidence reports a controversial extra-gonadal role of follicle stimulating hormone (FSH). Conflicting data support that the association between FSH and obesity might be maintained by a direct or even indirect effect to the adipose tissue. The aim of this study was to evaluate the associations between FSH concentrations and various obesity indices in women after menopause.Methods: This cross-sectional study included 420 postmenopausal w...

Bile acids (BA) are potent steroid hormones that mediate a variety of metabolic effects. They play a pivotal role in cholesterol catabolism, intestine nutrient absorption, and regulate lipid, glucose and energy metabolism. 5-Beta-Reductase (AKR1D1) is a key enzyme in the BA synthesis pathway, required for cholesterol metabolism into bile acids. We generated a novel global AKR1D1 knockout (KO) mouse which, as expected, has decreased total serum and hepatic BAs and altered BA co...

Introduction: Patients with systemic sclerosis may develop cancer. The development of malignant hematological diseases has also been described in patients with systemic sclerosis. These patients may also be prone to the development of lymphoma, in most cases a B-cell lymphoma.Aim: The aim was to describe the case of a patient with systemic sclerosis who had a non-Hodgkin’s lymphoma and developed primary hypothyroidism.Case rep...

Introduction: Diseases of the gastrointestinal tract may have on effect on bone quality manifesting either as osteomalacia or as osteoporosis. Gastritis may have an effect on bone as it requires long term treatment with proton pump inhibitors. Gastrointestinal neoplasms may be accompanied by nutrient malabsorption. These diseases may also be related with vitamin D deficiency.Aim: The aim was to describe two cases of gastrointestinal diseases, namely chro...
