Precedents: Thirty-nine year old Woman. Classic phenylketonuria diagnosed for neonatal screening in Germany. Good adherence to the diet from the infancy, with good metabolic control. Not response to test with BH4.Pregnancy in 2007 with good controls of phenylalanine (Phe). Son with congenital cardiopathy.Evolution: In 2013 she planed new pregnancy, departing from very good controls (<4 mg/dl) and ingestion of 22–24 Phe&#14...

Introduction and objectives: Hyperglycemia is present in about 25% of hospitalized patients. His control is common deficient. Consequently it increases the average stay, infection rates and mortality. In order to improve we present a comprehensive protocol.Methods: We developed algorithms of subcutaneous insulin therapy for non-critical patients, insulin therapy i.v. for critical patients, management of hypoglycemia, fasting situations, diabetic ketoacid...

Introduction: Parenteral nutrition (PN) is indicated in patients in which gastrointestinal tract is inaccessible or is severely affected. In our hospital, specialists often use commercial three-compartment bags of PN that provide standard nutritional requirements regardless a total parenteral nutrition (TPN) with macro and micronutrients adjusted to each patient by Endocrinology and Nutrition Service.Objectives: To assess the use of commercial premixed P...

Background: Many patients with differentiated thyroid cancer (DTC) are treated with radiodine (I-131) after thyroidectomy, while they are hypothyroid and all are submitted to withdrawal of LT4 periodically for the evaluation of their disease. Among the tests used for follow-up is serum thyroglobulin (Tg) as a tumor marker, and occasionally, total body scan with I-131. Maximal sensitivity of the aforementioned tests is established in the hypothyroid state, under elevated thyrot...

Introduction: Fine needle aspiration biopsy (FNAB) is the initial investigation of choice for thyroid nodules.Methods: A total of 563 patients (106 males/457 females) underwent FNAB for the same number of thyroid nodules. Their mean age was 56.1±14.1 years. We correlated the demographic profile (age and gender) and sonographic features of these nodules with the FNAB outcome. The Bethesda system for reporting thyroid cytopathology was used.<p cla...

With the increase in incidence of type 1 diabetes in children and young people (CYP) and the use of intensive insulin therapies, paediatric diabetes teams are under increasing pressure to support school staff with the day to day management of their pupils with diabetes. The CYPWMDN have developed a study day to provide basic diabetes awareness education to all school staff in the West Midlands (WM) region. This work also meets the training and support responsibilities of diabe...

Background: Hypopituitarism can occur post trans-sphenoidal adenomectomy(TSA). Accurate prediction of HPA axis recovery would inform hydrocortisone replacement strategies but there are limited studies on this. In our centre, HPA axis is assessed with pre-operative short synacthen test (SST), day-8 post TSA 9am cortisol and 6-week post-TSA SST. Patients are commenced on hydrocortisone post TSA until 6 weeks review.Methods: We performed a single-centre, lo...

Background: Obesity is a major medical health problem. Human brown adipose tissue (BAT) is potently activated by cold exposure and is a potential novel anti-obesity target. The current gold standard for measuring BAT activity in humans is 18F-FDG PET/CT. However it has two major limitations – exposure to ionizing radiation and high cost. Since BAT is a thermogenic organ located in the supraclavicular and neck regions, we hypothesised that an increase in tempera...

Background: Obesity is a global health concern. Elevating energy expenditure (EE) would be a highly effective treatment approach to treat obesity but no current drugs can safely achieve this. Cold exposure potently increases EE through brown adipose tissue (BAT) thermogenesis in humans. Glucagon elevates EE via BAT in rodents but the mechanism in humans is unknown. We investigated for the first time the mechanism by which glucagon increases EE in humans....

Introduction: Some authors consider aldosteronism to be a spectrum, ranging from aldosterone-associated (or low-renin) hypertension (AAH) to primary hyperaldosteronism (PHA) due to bilateral adrenal hyperplasia. Thus, blood pressure (BP) response to mineralocorticoid-receptor blockade (MRB) could be similar.Methods: Retrospective analysis of 60 patients. Screening per Endocrine Society guidelines, positive screening: aldosterone (pg/ml) to direct-renin (...
