BACKGROUND AND OBJECTIVES: Vitamin D3 (cholecalciferol) dose required to maintain sufficiency in non- Caucasian women with postmenopausal osteoporosis (PMO) inthe tropics has not been well studied. Some guidelines mandate 800-1000 IU vitamin D/day but the Endocrine Society (US) advocates 1500-2000 IU/day to maintain 25-hydroxyvitamin-D (25(OH)D) concentration at >75 nmol/L. We aimed to establish oral cholecalciferol dose required to maintain 25(OH)D concentration at >75 nmol/L in PMO Chinese Malaysian women, postulating lower dose requirements amongst light-skinned subjects in the tropics...

Aldosterone producing adenoma and bilateral adrenal hyperplasia are the two most common subtypes of primary aldosteronism (PA) that require targeted and distinct therapeutic approaches: unilateral adrenalectomy or lifelong medical therapy with mineralocorticoid receptor antagonists. According to the 2016 Endocrine Society Guideline, adrenal venous sampling (AVS) is the gold standard test to distinguish between unilateral and bilateral aldosterone overproduction and therefore, to safely refer patients with PA to surgery...

PURPOSE: We investigated the impact of different cut-offs on the prevalence of 25-hydroxyvitamin D [25-(OH)D] deficiency. METHODS: We used baseline data of 4149 participants (45-75 years, 50% women) of the population-based Heinz Nixdorf Recall study. Serum 25-(OH)D was measured with the Roche Cobas assay. Quartiles (p25, p50, and p75) were calculated. Data were stratified by months, sex, and age. According to the recommendations of 'Dachverband Osteologie', Endocrine Society and National Institute of Health we used 25-(OH)D thresholds of 12, 20, and 30 ng/ml to estimate vitamin D deficiency...

Classical thinking in endocrine physiology squeezes our diagnostic handling into a simple negative feedback mechanism with a controller and a controlled variable. In the case of the thyroid this is reduced to TSH and fT3 and fT4, respectively. The setting of this tight notion has no free space for any additions. In this paper we want to challenge this model of limited application by proposing a construct based on a systems approach departing from two basic considerations. In first place since the majority of cases of thyroid disease develop and appear during life it has to be considered as an acquired condition...

Congenital adrenal hyperplasia (CAH) is an endocrine condition that requires parents to administer steroids up to three times daily, supplementing maintenance doses with oral or injectable doses during times of illness. The purpose of this integrative review was to explore the management, care, and associated health issues for children with CAH and the family response to the condition. Four literature indexes were searched, with 39 articles included. Four themes emerged: (a) Health- and Development-Related Issues, (a) Effects of Excess Androgens, (c) Life Experience of CAH, and (d) Managing and Averting Adrenal Crisis...

BACKGROUND: Though randomized clinical trials have demonstrated a reduction in second breast events with endocrine therapy among women with ductal carcinoma in situ (DCIS), use of these therapies remains highly variable. The purpose of this study was to evaluate patient and treatment-related factors associated with endocrine therapy initiation and medical oncology specialty utilization after DCIS. MATERIALS AND METHODS: We identified women with a DCIS diagnosis during 2006-2010 in the North Carolina Central Cancer Registry with linked public and private insurance claims in the University of North Carolina Integrated Cancer Information Surveillance System data resource...

PURPOSE: Everolimus has been shown to be effective for advanced pancreatic neuroendocrine tumours (pNETs), but its positioning in the therapeutic algorithm for pNETs is matter of debate. METHODS: With the aim to shed light on this point, we performed an up-to-date critical review taking into account the results of both retrospective and prospective published studies, and the recommendations of international guidelines. In addition, we performed an extensive search on the Clinical Trial Registries databases worldwide, to gather information on the ongoing clinical trials related to this specific topic...

Tumourigenesis is a relatively common event in endocrine tissues. Currently, specific guidelines have been developed for common malignant endocrine tumours which also incorporate advances in molecular targeted therapies (MTT), as in thyroid cancer and gastrointestinal neuroendocrine malignancies. However, there is little information regarding the role and efficacy of MTT in the relatively rare malignant endocrine tumours mainly involving the adrenal medulla, adrenal cortex, pituitary and parathyroid glands...

Low carbohydrate diets for the management of type 1 diabetes have been popularised by social media. The promotion of a low carbohydrate diet in lay media is in contrast to published pediatric diabetes guidelines that endorse a balanced diet from a variety of foods for optimal growth and development in children with type 1 diabetes. This can be a source of conflict in clinical practice. We describe a series of 6 cases where adoption of a low carbohydrate diet in children impacted growth and cardiovascular risk factors with potential long-term sequelae...

BACKGROUND: Despite being widely recognized as the most common form of secondary hypertension, among the general hypertensive population the true prevalence of primary aldosteronism (PA) and its main subtypes, aldosterone-producing adenoma (APA) and bilateral adrenal hyperplasia (BAH), remains a matter of debate. OBJECTIVES: This study sought to determine the prevalence and clinical phenotype of PA in a large cohort of unselected patients with hypertension, consecutively referred to our hypertension unit, by 19 general practitioners from Torino, Italy...

Williams Syndrome (WS) is a contiguous gene deletion disorder, caused by the deletion of approximately 26-28 genes from chromosome 7 (7q11.23). Individuals with WS have complex medical, developmental, and behavioral features, requiring multidisciplinary and interdisciplinary collaboration. Guidelines detailing the identification, evaluation, and monitoring of individuals with WS need clarification, especially for primary care providers who are first-line in their management. This report summarizes the proceedings of the 2016 Professional Conference on WS in Columbus, OH...

J Daniels, J M Turner-Cobb
Consideration of psychological distress in long term endocrine conditions is of vital importance given the prevalence of anxiety and depression in such disorders. Poor mental health can lead to compromised self-care, higher utilisation of health services, lower rates of adherence, reduced quality of life and ultimately poorer outcomes. Adjuvant psychological therapy offers an effective resource to reduce distress in endocrinological disorders. While the vast majority of work in this area has focused on psychological screening and intervention in diabetes, identification and recognition of psychological distress is equally important in other endocrinological conditions, with supportive evidence in Polycystic Ovary Syndrome and Addison's disease...

Lower blood glucose values are common in the healthy neonate immediately after birth as compared to older infants, children, and adults. These transiently lower glucose values improve and reach normal ranges within hours after birth. Such transitional hypoglycemia is common in the healthy newborn. A minority of neonates experience a more prolonged and severe hypoglycemia, usually associated with specific risk factors and possibly a congenital hypoglycemia syndrome. Despite the lack of a specific blood glucose value that defines hypoglycemia, concern for substantial neurologic morbidity in the neonatal population has led to the generation of guidelines by both the American Academy of Pediatrics (AAP) and the Pediatric Endocrine Society (PES)...

PURPOSE OF REVIEW: According to an Endocrine Society Clinical Practice Guideline published in June 2010, testosterone replacement therapy (TRT) should be administered only to men who are hypogonadal with documented low testosterone level on two morning measurements. This recommendation was based on previous studies that did not show an increased risk in cardiovascular events with TRT. In contrast, recent studies did show an increased risk which prompted the FDA to investigate further...

Molting is critical for growth, development, reproduction, and survival in arthropods. Complex neuroendocrine pathways are involved in the regulation of molting and may potentially become targets of environmental endocrine disrupting chemicals (EDCs). Based on several known ED mechanisms, a wide range of pesticides has been developed to combat unwanted organisms in food production activities such as agriculture and aquaculture. Meanwhile, these chemicals may also pose hazards to nontarget species by causing molting defects, and thus potentially affecting the health of the ecosystems...
