Aim: To assess usage of newly available rapid-acting insulin analogues in the antenatal diabetes clinic, and to determine whether introduction of these agents has influenced glycaemic control.Methods: We analysed our diabetes antenatal clinic attendances from April 2002 to June 2003 using the DIABETA 3 database. 290 pregnant women were seen over this period which was divided into three groups: Group I (April to September 2002), Group II (October 2002 to ...

Mutations in the RET gene are responsible for Multiple Endocrine Neoplasia type 2A (MEN2A), characterised by Medullary Thyroid Carcinoma (MTC) and Pheochromocytoma (PCC). It is well recognised that there is a genotype-phenotype correlation regarding likelihood of endocrine tumour development. The American Thyroid Association (ATA) has published predictive grading to guide clinical management of patients with RET mutations.Aim: In this study, we aim to as...

IntroductionParagangliomas (PGLs) are neuroendocrine tumours that arise from neural crest-derived chromaffin cells. They can develop anywhere these cells exist from the base of the skull to the pelvis. All PGLs have neuro-secretory potential and can produce symptoms due to catecholamine excess. While the majority are benign they do have malignant potential. Mediastinal PGLs are rare and often have a strong genetic predisposition. A higher proportion of t...

Bladder Paragangliomas (PGLs) are a rare manifestation of sympathetic chain PGLs and occur in prone patients with SDH mutation.They often display an aggressive phenotype with metastatic disease and require long-term follow up. SDHB immunostaining plays a significant role in initial risk stratification and facilitating appropriate genetic testing. We report four cases illustrating diagnostic management and outcome issues in this rare neuroendocrine pathology; two with SDHB muta...

75% of patients presenting with a phaeochromocytoma (PCC) or paraganglioma (PGL) have no relevant family history, but a germline pathogenic variant is identified in 30–40%. In our genetic endocrine clinic, over 80% of patients with malignant PCC or PGL have SDHA/SDHB/SDHC/SDHD/MAX or FH pathogenic variants identified, confirming high heritability in severe disease.We describe a series of seven patients from fiv...

Bladder Paragangliomas (PGLs) constitute < 1% of all bladder tumours and 5% in our patient cohort of 80 patients with tumours due to SDH deficiency. They often display an aggressive phenotype with metastatic disease and require long-term follow up. SDHB immunostaining plays a significant role in initial risk stratification and facilitating appropriate genetic testing. We present four cases of bladder PGLs; two with SDHB mutation, one SDHA and one is awaiting extended genet...

Background: Tertiary adrenal insufficiency (TAI) is a complication of long-term exogenous steroid use which results in suppression of the hypothalamic-pituitary-adrenal (HPA) axis. The short synacthen test (SST) is used to assess HPA axis function and recovery during glucocorticoid weaning. This study examined the effect of steroid preparation, dosage and therapy duration on HPA axis suppression.Method: A retrospective analysis of 950 SSTs performed betw...
