Introduction: While severe GH deficiency (GHD) is a well-established feature of Sheehan’s syndrome (SS), the effects of GH deficiency in these patients has not been extensively investigated. In the present studyh we evaluated the cardiovascular risk in patients with SS.Methods: Twenty female with SS and well-treated with cortisone and thyroid hormones was included. Metabolic syndrome according to IDF-2005 criteria and insulin resistance estimated by...

Pituitary apoplexy caused by pure infarction is rare. Here we present three cases of pituitary macroadenoma infarction following hypotension.1. An 84 year old gentleman had a 2 × 2 cm pituitary macroadenoma causing chiasmal compression and a bitemporal hemianopia. He had panhypopituitarism and was on prednisolone, thyroxine and testosterone replacement. Before surgical intervention of the macroadenoma, he fell and broke his humerus, which requi...

Increased mortality due to atherosclerotic cardiovascular disease has been described in adult patients with hypopituitarism, although the precise underlying mechanisms remain undetermined. Various abnormalities of coagulation and fibrinolysis occur in patients with thyroid diseases. Conversely, there are conflicting reports concerning the effects of growth hormone replacement on coagulation and fibrinolytic pathways in adults with hypopituitarism, and there are limited data on...

Sheehan’s syndrome (SS) may be defined as development of anterior pituitary ischemic necrosis, first of which is caused by failure to meet the blood build-up required due to pituitary expansion secondary to lactotroph cell proliferation during pregnancy. Vasospasm, thrombosis and vascular compression of hypophyseal arteries have been described among the possible causes of SS. Additionally, expansion of pituitary gland, small sella, disseminated intravascular coagulation (...

Introduction: Despite the significant associated cardiovascular morbidity, as well as the significant economic implications, little consideration has been given towards population screening for the Metabolic Syndrome (MetS). Therefore, we wished to estimate the prevalence of MetS, using both the recently published IDF, as well as the previously defined Cholesterol Education Program Adult Treatment Panel III (ATPIII), criteria. Additionally, we hypothesised that simple, inexpen...

Objective: There is currently extensive debate regarding elevated TSH (Thyroid Stimulating Hormone) concentrations and associated cardiovascular risk. This study investigated whether correlations exists between TSH concentrations within the accepted range of normality and increasing cardiovascular risk.Design: We performed a cross-sectional study of 728 asymptomatic women aged 45–60 years attending for thyroid screening over a twelve month period. P...

Elevated serum prolactin (PRL) is common, with many potential causes. We performed a retrospective audit of patients with hyperprolactinaemia from 2006 to 2008, aiming to identify the clinical indications for prolactin testing, the aetiology identified and the treatment instigated. Medical notes for 83 patients (55 female, mean age 41 years (range 17–95)) with PRL >700 mU/l were retrospectively reviewed. Indications for testing included: seizure or suspected seizure (...

Synthesis of thyroid hormones by the fetal thyroid requires the passage of iodide through the placenta. In the thyroid active iodide transport is facilitated by three transporters, the sodium iodide symporter (NIS), Pendrin (PDS) and the recently described the human apical iodide transporter (hAIT). Simultaneous expression of all three transporters appears to be thyroid restricted and although extrathyroidal expression of individual transporters has been reported, relatively l...

Background: Immune related adverse events (iRAEs) of the endocrine system are commonly recognised in Checkpoint Inhibitor Therapy treatment with current research suggesting clinically significant endocrinopathies occur in 10%. As the use of these drugs continues to rise, so too does the importance of routine endocrine monitoring in order to avoid potentially life-threatening adverse-events.Aims: To establish the frequency, severity, management and outcom...

We describe a case of 31 year young lady with Type 1 Diabetes, who started experiencing reduction in insulin requirement and hypoglycaemia episodes due to an endocrine disorder following Pregnancy. She presented with recurrent episodes of documented hypoglycaemia and amenorrhea following successful pregnancy. Her basal insulin requirements fell from 36 units to 24 units per day and she required little if any insulin as bolus (0.5 unit for every 10 gm). She did not breast feed....
