Cushing’s syndrome results from exposure to excess glucocorticoids. Ectopic Cushings is endogenous ACTH dependant form of Cushing’s associated with markedly raised ACTH and cortisol levels. This leads to an impaired immune response, setting the stage for occurrence of opportunistic infections. Nocardia is a gram positive bacterial infection caused by aerobic actinomycetes in genus Nocardia. We report a series of patients diagnosed with ectopic Cushings, with growth o...

The TNF members sRANK-L & Osteoprotegerin (OPG) are essential paracrine mediators of osteoclast function in vitro. The aim of this study was to establish the relationship between 25-hydroxyvitamin D and sRANK-L and OPG in plasma of osteoporotic patients.The study population consisted of 185 osteoporotic women (mean age 62.4 years), with bone mineral density (BMD) more than 2.5 SD below the young adult value, and 185 age-matched controls, with normal ...

The Osteoprotegerin (OPG) RANK and RANK-L system is a novel paracrine system that forms part of the mechanism of bone turnover. The aim of this study was to explore if the OPG/ RANK-L system, detectable in blood, is related to bone mineral density.The study population consisted of 185 osteoporotic women (mean age 62.4 years), with bone mineral density (BMD) more than 2.5 SD below the young adult value, and 185 age-matched controls, with normal bone miner...

If calcium intake and absorption are insufficient plasma calcium is maintained but bone loss ensues. The relationship between calcium intake and parathyroid hormone (PTH) levels in serum of 186 women (mean age 62.4 years) with bone mineral density >2.5 SD below the young adult value and 586 age-matched controls with normal bone mineral density was studied.The approximate calcium intake from dairy products was assessed by a simple questionnaire. All 77...

Introduction: Thyroid dysfunction is common affecting 5–10% of the adult population. Cardiovascular disease, including acute myocardial infarction (AMI), has been suggested as one of the adverse outcomes of thyroid disease. Furthermore, individuals with thyroid dysfunction at the time of AMI have worse outcomes. Despite this, there is scarce data on the prevalence of thyroid dysfunction in patients with AMI. We conducted a prospective observational multi-cen...

The importance of the sRANK-L / RANK / Osteoprotegerin (OPG) system in osteoclast function has clearly been demonstrated in the rat. Activating and inactivating mutations lead to severe disturbances of bone remodelling.Since this early animal work, there have been several studies designed to assess the importance of sRANK-L / RANK / OPG in diseases of the human skeleton. sRANK-L and OPG are measurable in blood.This cross-sectional ...

Background: Bilateral cataracts are rarely the initial symptom of diabetes mellitus (DM). Patients with DM who developed cataracts usually have DM for many years. The prevalence of early cataracts in paediatric DM ranges between 0.7 and 3.4%. We report a case of DM diagnosis following onset of blindness due to new bilateral cataracts.Case description: 13-year-old Caucasian girl presented with rapidly declining vision for 2 months. She was blind 2 weeks p...

Pharmacokinetics and tolerability of a new a bioadhesive buccal testosterone tablet in testosterone deficient men.RJM Ross, A Jabbar, H Jones, B Roberts, K Dunkley, A Long, H Levine, DR CullenObjectives: A phase I single centre, open label study of the pharmacokinetics and tolerability of a buccal testosterone tablet (COL1621). Design: The study was approved by The South Sheffield Ethics Committee. Twelve testosterone deficient males were treated with the buccal tablet...

Background: Non-classic adrenal hyperplasia (NCAH), comparatively a rare disease, is characterised by mild to moderate hyperandrogenemia, hirsutism, oligomenorrhea, insulin resistance which incidentally are the hallmarks of polycystic ovary syndrome (PCOS)- a common disorder among reproductive aged women. The data on 17-hydroxyprogesterone (17-OHP)serum levels in NCAH has been reported globally but there is limited data available regarding the normal range among healthy Indian...
