Objectives: This prospective study aimed at investigating (1) the prevalence of vitamin D deficiency and insufficiency in diabetic adolescents and children in a multi-ethnic cohort, and (2) any association between vitamin D status and ethnic background, glycaemic control (HbA1C), biomarkers of metabolic bone health and lipids.Methodology: Venous blood was drawn from 199 patients with type 1 diabetes (mean age ± SD, 8.2 ± 3.7 years) and 48 patients ...

Background: Twice-daily formulation of pasireotide, a pituitary-directed therapy, is approved for treatment of Cushing’s disease. Here we present data from a phase III study designed to evaluate the more convenient once-monthly long-acting release (LAR) formulation of pasireotide (approved for acromegaly) in patients with Cushing’s disease.Methods: Patients with persistent, recurrent, or de novo Cushing’s disease (not candidates for surger...

Introduction: The clinical outcome of patients with adrenal insufficiency (AI) has been shown to be less favorable than previously thought. Clinical studies have shown increased mortality, reduced cardiovascular and skeletal health and compromised quality of life, but the impact of this upon healthcare burden is unknown. This research utilised real-world evidence to compare comorbidities, healthcare utilization and expenditures in patients with AI.Method...

Background: Bony deformity due to primary hyperparathyroidism is a rare entity in children.Methods: We describe two children who presented with genu valgum to the Endocrine Department. Ten children with primary hyperparathyroidism presenting with genu valgum have been reported in literature and have been reviewed by us.Results: Biochemical investigations revealed parathyroid hormone dependent hypercalcemia despite a deficiency of v...

Introduction: Primary malignant thyroid teratoma is a rare neoplasm. Even rarer is the concomitance of the mentioned tumor and papillary thyroid cancer.Case report: We report a case of a 44-year old woman diagnosed with Hasimoto thyroiditis and multinodular, non-toxic goiter since 2004. The two larger, initially non palpable nodules were located in right thyroid lobe, 16 and 12 mm in diameter respectively. Under suppressive thyroxine therapy the diameter...

Introduction: Metformin induced impaired vitamin B12 absorption leading to fall in serum cobalamin levels has been described in literature as early as 1971. Approximately 10% of patients and in some studies 30% of patients on metformin therapy developed metformin related cobalamin deficiency. The risk of cobalamin deficiency is comparatively more among patients with vegetarian diet than in non-vegetarians.Objective: To evaluate the effect of dose and dur...

Mitotane (o,p’DDD) is an effective oral adrenolytic agent for treatment of advanced adrenocortical carcinoma (ACC). Inhibition of cortisol biosynthesis has been described. Cortisol metabolic clearance rate is unchanged, but decreased cortisol biovailability is indicated by increased dose requirement for hydrocortisone replacement during mitotane treatment. Urinary excretion of common cortisol metabolites (CM) has been reported to be normal but with increase of 6β-hyd...

Introduction: Graves’ disease is associated with mild hypercalcemia in about 1/5th of cases. T3, through its nuclear receptor activates osteoclasts resulting in accelerated bone turnover. Although mild hypercalcemia is common in Graves’ disease, symptomatic hypercalcemia is rare. We describe a case who presented with thyrotoxic storm and hypercalcemia.Case report: 52-year-old lady presented with thyrotoxic symptoms of weight loss, dysphagia for...

Background /Methods: Adrenal incidentalomas pose a significant burden to endocrinology services in assessing the clinical significance of these lesions. Following vetting of the incidentaloma referrals, the patients at our centre are initially seen in a nurse-led clinic for biochemical investigations and to ensure completion of radiology assessment using a structured proforma. This step facilitates efficient patient flow and quicker decision making. The clinical outcomes of th...

Background: Adrenal insufficiency is a rare but potentially life threatening complication of the antiphospholipid antibody syndrome (APS). The adrenal gland is the most commonly involved endocrine organ with adrenal insufficiency reported in 0.4% of APS cases. Adrenal failure more often follows other thromboembolic manifestations of APS.Case report: We report a 25-year-old male with systemic lupus erythematosus (SLE) with antiphospholipid syndrome (tripl...
