Hypomagnesaemia can cause Hypocalcaemia as magnesium interferes with parathyroid hormone action and secretion. It also causes hypokalemia due to defective membrane ATPase or urinary potassium loss. We present two patients who were admitted to our hospital with symptoms and signs of hypocalcaemia secondary to drug-induced hypomagnesaemia and describe the lessons learned.Patient 1: A 46 year-old lady presented with “pins and needles” and muscle c...

Prolactinomas are the most common pituitary adenomas. The treatment is primarily medical with dopamine agonists. The improvements in prolactin levels are accompanied by reduction in the tumour size in the majority of cases. We report a patient with a macroprolactinoma whose tumour enlarged despite achieving normal prolactin levels.A 55-year-old gentleman was referred to the ophthalmologist with worsening vision in the left eye. Clinical examination revea...

Hirsutism affects 8% of women and forms an important reason for referral to the endocrine services in patients with polycystic ovarian syndrome (PCOS). Although antiandrogens are the mainstay in treatment, one needs to bear in mind that they are not without undesirable side effects.We present the case of a 37-year old woman, diagnosed with PCOS based on menstrual irregularities and typical ultrasound appearances of her ovaries. Her main concerns were hir...

Aim: To evaluate local management of thyroid nodules in comparison with the British Thyroid Association guidelines.Methods: All patients who had fine needle aspiration cytology (FNAC) for a thyroid nodule in 2004 and 2005 were included. Data collected included: patients’ age, gender, thyroid status, FNA Cytology (including repeats) and THY classification, surgical intervention and histology (if applicable).Results: 97 patients...

Once daily Thyroxine is the treatment of choice for hypothyroidism. The dose of Thyroxine needed varies with a mean of 1.6 mcg/kg bodyweight a day. The most common cause for requiring larger doses is non-compliance although other causes such as malabsorption and drugs should be excluded. In this abstract we describe two patients with hypothyroidism that required large doses of thyroxine secondary to poor compliance in which supervised once weekly thyroxine therap...

Hypopituitary patients on conventional hormone replacement, excluding GH have a reduced quality of life (QoL) and an increased risk of cardiovascular mortality. NICE guidelines on criteria for initiation and maintenance of therapy rely on QoL score defined by the Adult GHD assessment (AGHDA) questionnaire. However, it is uncertain how this score is related to other biological effects such as vascular risk.Methods: Sixteen hypopituitary patients were recr...

AımThe aim of this study is to investigate the attitude of physicians, who are specialized in internal medicine, endocrinology, nurology and cardiology, on LDL target levels and antilipidemic treatments in Turkey.MethodsThis study outlines attitudes of physicians towards the guideline-recommended LDL target levels in diabetic dyslipidemia. An invitaiton to fill a questionnaire on demographic and professi...

Aim: To audit radioactive iodine (RAI) treatment.Methods : A retrospective audit of thyrotoxic patients, who attended the one-stop RAI clinic, between April 2005 and February 2006.Results: We included 74 patients (60 females, 14 males) with a median age 54 (22–85) years.Before RAI: Smoking history was recorded in 19/74(26%) patients. 44/74(59%) patients received drug treatment for two years or mor...

A common NOS3 polymorphism (the gene which encodes endothelial nitric oxide synthase), a variable number of tandem repeats within Intron 4 has been associated with cardiovascular disorders in which nitric oxide bioactivity is impaired including myocardial infraction. Consistent characteristic changes in the pressure pulse wave shape have been associated with ageing, risk factors for cardiovascular disease and impaired NO bioactivity. Therefore pulse waveform analysis can be ut...

Transient insulin resistance (IR) is a recognized facet of metabolic phenotype in pubertal boys. However, it remains unknown how the Y chromosome and adolescence as a transition from pubertal period to adulthood affects markers of insulin resistance, particularly in relation to body mass index, blood pressure and androgens.We analyzed associations among indicators of insulin resistance, total adiposity, androgen profile and the Y chromosome in a sample of 1745 males divided in...
