Management of hypogonadism from birth to adolescence
Publication date: Available online 6 June 2018Source: Best Practice & Research Clinical Endocrinology & MetabolismAuthor(s): Sasha R. Howard, Leo DunkelManagement of patients with hypogonadism is dependent on the underlying cause. Whilst functional hypogonadism presenting as delayed puberty in adolescence is relatively common, permanent hypogonadism presenting in infancy or adolescence is unusual. The main differential diagnoses of delayed puberty include self-limited delayed puberty (DP), idiopathic hypogonadotropic hypogonadism (IHH) and hypergonadotropic hypogonadism. Treatment of self-limited DP involves expectant obse...

Parathyroid hormone independent hypercalcemia in adults
Publication date: Available online 18 June 2018Source: Best Practice & Research Clinical Endocrinology & MetabolismAuthor(s): Jens Bollerslev, Mikkel Pretorius, Ansgar HeckParathyroid independent hypercalcemia is characterized by suppressed parathyroid hormone (PTH) in the presence of hypercalcemia.Well known causes and mechanisms are redistribution of calcium from the skeleton, by malignant diseases; inadequately increased intestinal calcium uptake mediated by increased vitamin D activity, and reduced renal elimination due to medications. Frequent and infrequent causes are discussed, and more recent mechanistic models pre...

Sclerosing bone dysplasias
Publication date: Available online 18 June 2018Source: Best Practice & Research Clinical Endocrinology & MetabolismAuthor(s): Eveline Boudin, Wim Van HulThe group of sclerosing bone dysplasia's is a clinically and genetically heterogeneous group of rare bone disorders which, according to the latest Nosology and classification of genetic skeletal disorders (2015), can be subdivided in three subgroups; the neonatal osteosclerotic dysplasias, the osteopetroses and related disorders and the other sclerosing bone disorders. Here, we give an overview of the most important radiographic and clinical symptoms, the underlying geneti...

Non classical complications of primary hyperparathyroidism
Publication date: Available online 18 June 2018Source: Best Practice & Research Clinical Endocrinology & MetabolismAuthor(s): I. Chiodini, E. Cairoli, S. Palmieri, J. Pepe, M.D. WalkerSeveral studies suggested that the condition of primary hyperparathyroidism (PHPT) may be associated not only with the classical bone, kidney and gastrointestinal consequences, but also with cardiovascular, neuromuscular and articular complications, impaired quality of life and increased cancer risk. However, the only cardiovascular complications associated with PHPT, which seems to improve after parathyroidectomy, is left ventricular hypertr...

Update on bone density measurements and their interpretation in children and adolescents
Publication date: Available online 18 June 2018Source: Best Practice & Research Clinical Endocrinology & MetabolismAuthor(s): Natascia Di Iorgi, Katia Maruca, Giuseppa Patti, Stefano MoraFollowing the increased awareness about the central role of the pediatric age in building bone for life, clinicians face more than ever the necessity of assessing bone health in pediatric subjects at risk for early bone mass derangements or in healthy children, in order to optimize their bone mass accrual and prevent osteoporosis. Although the diagnosis of osteoporosis is not made solely upon bone mineral density measurements during growth...
