Background: Osteoporosis and increased fracture risk associated with cystic fibrosis (CF) are becoming more relevant with improved life expectancy in this disease. The evolution of CF-related bone disease remains unclear.Aims: To evaluate change in bone mineral density (BMD) in individuals with CF from age 10 to 30 y.Methods: Data from the UK CF Trust registry, which contains anonymised clinical information, was used to evaluate BM...

Background: Duchenne muscular dystrophy (DMD) is the most common muscular dystrophy, resulting in death at a young age. Corticosteroids improve muscle function and slow disease progression. However long-term steroid therapy is a significant risk factor for osteoporosis.Aim: To assess the effect of oral bisphosphonate (risedronate) treatment on bone mineral density in a cohort of steroid-treated children with DMD.Method: Annual bone...

Introduction/Aim: Congenital hyperinsulinism (CHI) is a cause of severe hypoglycaemia in infancy. Treatment of diazoxide unresponsive patients includes the use of somatostatin analogues (octreotide given either as four s.c. injections daily or via a pump). We aimed to evaluate the use of a long acting somatostatin analogue (Lanreotide) in children with CHI, switching them from daily oral diazoxide or s.c. Octreotide injections to 4 weekly Lanreotide injections.<p class="ab...

Introduction: Hyperinsulinaemic hypoglycemia (HH) represents the most common cause of hyperinsulinism in neonates, often termed as congenital hyperinsulinism of infancy (CHI). CHI is characterised by inappropriate raised insulin secretion from the pancreatic β-cells in relation to blood glucose concentration. Insulin suppresses NEFA and BOHB production. Neurological damage is a known risk associated with hyperinsulinaemic hypoglycaemia (HH).Aim: To ...

Polycystic ovary syndrome is the commonest cause of anovulation. The mechanism of the aberrant follicle development that is associated with anovulation remains unclear. However, data from human studies and from animal models of PCOS suggest that excess androgen production, the biochemical hallmark of PCOS, has a role in disordered follicle development. The aim of this study was to examine the direct effect of androgens on isolated mouse preantral follicles in culture. Multilay...

Aim: PCOS is associated with peripheral insulin resistance and we have previously shown that glucose uptake and metabolism are impaired in granulosa lutein (GL) cells of anovulatory women with PCOS (anovPCO). The aim of this study was to delineate insulin-signalling pathways in GL cells from women with anovPCO and to compare the response to insulin with that in GL cells from ovulatory women with (ovPCO) and without polycystic ovaries (controls).Methods: ...

Introduction: British Thyroid Association Guidelines state that the diagnosis of thyroid malignancy cannot be based on the results of an aspiration’s cytology alone and will usually require surgical removal for confirmation. There has been much debate about the management of indeterminate fine needle aspirations (Thy 3). Recent publications have reported that the prevalence of thyroid carcinoma following a Thy 3 result to be as high has 28%, emphasising the importance of ...

Aims: Treatment regimes for low testosterone are well established but reasons for treatment change and patient preferences are less well known. We looked at the type of testosterone replacement, subsequent modification of replacement and reason for that change.Methods: Data were collected from the electronic case notes of 50 patients on testosterone replacement for at least 6 months attending endocrine clinics in a University Teaching Hospital.<p cla...

Transphenoidal surgery is an effective treatment option in patients with pituitary tumours associated with compression of the optic chiasm or hormone hypersecretion. Surgery carries with it a risk of the development of new pituitary hormone deficits but also the potential for recovery of existing pituitary hormone deficits. We have examined data concerning pituitary function in 80 patients who underwent endoscopic transphenoidal pituitary surgery at Royal Preston Hospital....

Objectives: To establish the proportion of patients locally with potentially significant thyroid pathology not receiving specialist endocrine input. To look at the management of hyperthyroid patients within the Endocrinology service.Patients and methods: Utilising the laboratory database, 121 patients identified (97 female, 24 male; age range 17–93 years, average 55 years) with TFTs suggesting hyperthyroidism (raised fT4/fT3, and/or suppressed TSH) ...
