Orlistat and Metformin have both been shown to be beneficial in the treatment of Polycystic Ovarian Syndrome (PCOS), however, because Orlistat works by decreasing the absorption of dietary lipids, there is the potential to decrease absorption of lipophilic antioxidant substances with consequent decreased protection from oxidative stress. The objective of this study was to evaluate and compare the effect of treatment with orlistat vs. metformin on oxidative stress in pat...

Introduction: About 3% of patients treated with amiodarone develop thyrotoxicosis (amiodarone induced thyrotoxicosis, AIT). Steroids and carbimazole are the main treatment options with surgical thyroidectomy performed in resistant cases. Radioiodine is believed to be unhelpful based on presumed poor radioiodine uptake by thyroid tissue saturated with iodine. We present a case of AIT with a low technetium uptake being successfully treated with radioiodine ablation.<p class=...

Introduction: Vitamin D (Vit D) is required for maintaining optimal bone health and there is widespread campaign in the media for its use. There is however lack of awareness among the general public about therapeutic doses which if exceeded can result in harm. We present one such patient who was taking harmful quantities of vit D supplements procured over the internet which resulted in hypercalcaemia and renal failure.Case Description: 50year old lady, N...

38 year old woman presented with palpitations, chest tightness, dizziness and light headedness. There was no evidence of infection clinically or biochemically. She had a background of Alemtuzumab induced Graves’ thyrotoxicosis, relapsing remitting Multiple Sclerosis. Her regular medications included Carbimazole 20 mg three times a day, Amitriptyline 120 mg daily, Propranolol 40 mg four times a day, Tizanidine 2 mg daily (up to 18 mg), Tramadol 50 mg as required, Senna 7.5...

Introduction: Preoperative ultrasonography or Sestamibi scanning (or both) of the parathyroid glands could facilitate a focused or minimally invasive surgical approach. In this audit, we wanted to find out whether one form of imaging is superior to the other in correctly identifying a parathyroid adenoma, later confirmed on histology.Methods: Data were collected from consecutive patients who underwent parathyroidectomy for primary hyperparathyroidism, co...

Context: Respiratory failure as a component of severe hypothyroidism has high mortality and a number of pathological mechanisms have been proposed. These range from cerebral causes to neuromuscualr and pulmonary factors. Changes due to mucopolysacharide deposition in the lungs is another postulated mechanism, but radiological changes are hitherto not clinically demonstrated.Objective: A case of hypothyroidism with hypoxia associated with CT features sugg...

Objectives: There is strong epidemiological evidence that insulin resistance confers a significantly increased risk of cardiovascular disease independent of other cardiovascular risk factors. The aim of the study is to compare the insulin resistance levels in metabolic syndrome of polycystic ovarian syndrome (PCOS) with that of type 2 diabetes (T2DM).Methods: The biological variation of IR was assessed by measuring IR at four day intervals on 10 consecut...

ObjectiveIn polycystic ovarian syndrome (PCOS), C-reactive protein (CRP) concentration is elevated and inversely related to insulin sensitivity. However, no data exists on the biological variability of CRP in PCOS.MethodsBlood samples were collected after an overnight fast at four-day intervals on 10 consecutive occasions from 12 patients with PCOS and 11 weight and age matched Caucasian women (controls). Dup...

There has been controversy over the diagnostic utility of the LH/FSH ratio in polycystic ovarian syndrome, with more recent guidelines excluding it as a diagnostic test. However, LH/FSH is still often requested for that purpose and in our institution, 20% of the 12,000 annual requests for LH/FSH tests requested in a one year period had PCOS detailed on the card, at a cost of over £37,000.Objective: The aim of this study was to ascertain the biologi...

Natriuretic peptides BNP and NTpro-BNP have been suggested as being useful for the diagnosis of congestive heart failure, and have been shown to have excellent negative predictive value for excluding severe systolic left ventricular dysfunction.We have shown previously that changes in thyroid function are associated with changes in concentrations of other low molecular weight molecules through the changes on renal function. Therefore, the aim of this stu...
