Introduction: Non-alcoholic steatohepatitis (NASH) is part of the spectrum of non-alcoholic fatty liver disease (NAFLD). NASH commonly occurs in patients with type 2 DM and is less recognised in type 1 DM. The natural history of NASH in adult patients suggests potential development of progressive fibrosis and cirrhosis. However, secondary glycogenosis, commonly occurs in type 1 DM, is reversible when good glycaemic control is achieved, but may be misidentified as NASH b...

C-type natriuretic peptide (CNP) has recently been implicated as a key meiotic arrest factor in oocytes, and mechanistic studies suggest that the transcriptional regulation of the CNP gene (Nppc) and of its receptor, GC-B (Npr2) is sensitive to gonadotrophin-dependent cAMP accumulation. We have shown CNP to be a major regulator of gonadotrophs in the pituitary, but have yet to establish how either Nppc or Npr2 are transcriptionally controlled locally. In the current study, the...

Somatostatin (sst) receptors are expressed in many tissues and multiple subtypes are often present in the same cells. Their activation by endogenous sst as well as by sst-analogues leads to inhibition of secretion and growth in some tumor, such as the neuroedocrine ones.Pheochromocytomas (Pheos) and paragangliomas (PGLs) are neural crest-derived tumors which can be sympathetic or parasympathetic in origin and present themselves as sporadic or familial. T...

Introduction: Interferon treatment for hepatitis C has been associated with Graves’-like thyroiditis, developing in rare instances severe ophthalmopathy. The usual management is interferon withdrawal and high-dose corticosteroids, but it may interfere with the resolution of hepatitis. Hereby we report a case successfully treated with radiotherapy, which in our knowledge has never been previously reported.Case report: A 52-year-old woman was diagnose...

Dyslipidemiαs should be managed from childhood for prevention of early atheromatic vascular lesions and premature cardiovascular disease in adult life.Aim: We examined the frequency of different types of dyslipidemiα in children and the results on blood lipids of lifestyle intervention (diet and exercise).Patients and methods: We studied retrospectively 136 children, 74 boys and 62 girls, mean chronological age 8.5±3...

Background: Asian has higher prevalence of diabetic nephropathy and end-stage renal disease as compared to Caucasian. No study to date has evaluated whether multifactorial intervention was associated with remission of microalbuminuria in type 2 diabetic Asian population. We evaluated the effect of tightly controlling multiple factors on the remission of diabetic nephropathy in type 2 diabetic Chinese with microalbuminuria.Materials and methods: A total o...

Sporadic Medullary thyroid carcinoma (MTC) is an uncommon thyroid cancer. The prevalence has been studied in two large European studies(1,2). Serum calcitonin provides a highly sensitive and specific tumour marker for this. We shall present a case which typifies the presentation of MTC and discuss its relevance.A 71-year-old gentleman of Italian descent was admitted in 2001 with left lower limb cellulitis. It was documented that he had an incidental goitre, that had been p...

To investigate the blood pressure profile (BP) in active acromegaly and the effect of medical treatment of acromegaly on BP circadian rhythm, we studied 21 acromegalics before and after 3–60 months of treatment with somatostatin analogs (15/21) or pegvisomant (5/21) or both (5/21). Ambulatory 24-h BP was recorded. The 24-h mean BP (MBP), the mean systolic BP (SBP) and diastolic BP (DBP), the day-time (day) and night-time (night) MBP, SBP and DBP and the 24-h mean heart ra...

Cabergoline (CAB), a potent dopamine agonist, is one of the most effective neuromodulatory drug in the second line treatment of patients with Cushing’s disease (CD). The aim of the current study was to estimate the predictive value of the acute CAB administration on short and long term responsiveness to CAB treatment. Twenty CD patients (6 males, 14 females, 12–60 years) entered the study. The acute CAB test was performed evaluating serum cortisol every hour for 6 h ...

Introduction: Y-chromosomal azoospermia factor (AZF) microdeletions are one of the few well-established genetic causes of male infertility, specifically azoospermia or severe oligozoospermia. Since the introduction of a PCR-based method to easily detect the distinct deletion patterns, the screening of infertile men for Y microdeletions has become a very common genetic test performed frequently by a large number of laboratories. An external quality control scheme was establishe...
