The incidence of type 1 diabetes mellitus (T1DM) is rising. The demands of daily management, blood glucose variability and potential complications pose challenges in management of T1DM.The aim of this study was to determine the clinical and metabolic profiles of T1DM patients attending Midland Regional Hospital Portlaoise diabetes service in 2017 and to assess their microvascular and macrovascular complications.A retrospective anal...

We present a case of a 24 year old lady with known SDHB mutation. She was referred from the genetics clinic in view of a strong family history of premature paraganglioma at the age of 17. On initial clinic assessment she exhibits no symptoms suggestive of paraganglioma or pheochromocytoma. Her blood pressure is normal at 120/75. pulse of 60–80bpm. Physical examination was unremarkable Her Plasma normetanephrine done on two separate occasion were elevated at 1600 pmol/l a...

Objective: A descriptive study to summarize the experience on diagnosis of NET using various imaging modalities.Methods: Imaging was reviewed for 25 patients between 2002 and 2009 (22 MEN-1, 3 sporadic insulinoma). Of 13/25 had elevated fasting gut hormones. CT, MRI, endoscopic ultrasound (EUS), somatostatin receptor scintigraphy (SRS) and angiography were reviewed. (CT, MRI examined with arterial enhancement).Results: Most frequen...

We have previously attributed the hypoglycaemic effects of Syzygium cordatum leaf extract to crude ethyl acetate extract solubles (EAS) containing triterpenoid compounds. The present study was designed to isolate and characterize triterpene components EAS and investigate the antihyperglycaemic effects alone or in combination with insulin in non-diabetic and streptozotocin (STZ)-induced diabetic rats. EAS soluble extracts were obtained after defatting the S. cordatum<...

Previous studies from our laboratories indicate that the anti-diabetic effects of Syzygium cordatum (Hochst.) (Myrtaceae) leaf extract in streptozotocin-induced diabetic rats may be attributed in part to mixtures of triterpenes, oleanolic acid (OA) and ursolic acid (UA). For the bioactive compounds to have potential in diabetes management, they should also alleviate or prevent complications of diabetes mellitus; kidney function and cardiovascular disorders. This study i...

Background: In the first trimester, the foetus is dependent on circulating maternal thyroid hormones for normal brain development. Maintenance of euthyroidism is important throughout pregnancy and maternal hypothyroidism is associated with adverse foetal outcomes.Aim: To audit the management of pregnancies complicated by hypothyroidism in a joint antenatal endocrine clinic in comparison with the UK guidelines from the British Thyroid Association (2006).<...

A 63-year-old gentleman with hypopituitarism secondary to non-functioning pituitary macro adenoma, treated with trans sphenoidal surgery 16 years earlier, was admitted with chest pain. His ECG showed 3 mm ST elevation in the inferolateral leads, and his subsequent cardiac enzymes were consistent with acute myocardial infarction. A decision was made not to thrombolyse him, as any intracranial tumour is an absolute contraindication to thrombolysis. He was discussed with the tert...

A 64 old year old obese (BMI 31 kg/m2) Caucasian male was admitted to our hospital with general malaise, nausea, vomiting and dehydration. He gave no preceding history of polyuria, polydipsia or weight loss. He had been receiving oral corticosteroids for established ulcerative colitis. He was found to have random plasma glucose of 70.7 mmol/l, positive serum and urine ketones, and metabolic acidosis with PH 7.27, bicarbonate 13 mmol/l and base excess −12.4. Th...

BackgroundAppetite is complex, however to address the obesity epidemic, therapeutic agents would have to significantly influence appetite. Currently the most effective treatment for obesity is bariatric surgery because it reduces hunger and increases satiety. The satiety gut hormones such as peptide YY (PYY) and glucagon like peptide 1 (GLP-1) reduce appetite and food intake. Compared to lean and obese subjects, exaggerated postprandial responses of PYY ...

The integrity of bone marrow and its various haemopoeitic cells require several hormones including sex steroids. Sex steroids were used in the past to treat aplastic anaemia. A 27 years old Saudi male who underwent a resection of hypothalamic astrocytoma and developed panhypopituitarism was admitted to ICU with shunt related meningitis and noted to have thrombocytopenia of 90,000 anemia of 9.5 gldl, which progressed over the subsequent week following admission. He recovered fr...
