In the absence of age-related comorbidities, fracture risk remains significantly elevated in young and middle-aged adults with T1DM. Younger age does not mitigate against hip fracture risk in T1DM, and health professionals need to be aware of this risk. Further studies are needed to evaluate the mechanisms of fracture in T1DM.
Context
Multiple endocrine neoplasia 1 (MEN 1) is an autosomal dominant disease presenting as hyperplasia and neoplasia of parathyroid, pituitary and enteropancreatic tissues. Over 90% of gene carriers develop phenotypic disease by age 30 years, potentially with onset of asymptomatic disease during childhood and adolescence.
Objective
To describe the paediatric and young adult manifestations of MEN 1.
Design
Descriptive retrospective study of 180 patients with a common MEN1 genotype. The paediatric and young adult (age <22 years) manifestations were determined using hospital records and disease surveillance data.
Results
Primary hyperparathyroidism (PHPT) was identified in 42 patients (mean age 17.2 ± 3.3 years). Parathyroidectomy was performed in 16 (38.1%; mean age 17.8 ± 3.2). Four patients experienced recurrent PHPT (25%), and six (37.5%) developed permanent hypoparathyroidism. Pituitary disease was identified in 13 patients. Prolactinoma was found in nine patients (mean age 16.6 ± 2.6 years) of whom four (44.4%) had macroprolactinoma. Two patients required surgical intervention; dopamine agonists showed efficacy in six patients. Two patients with Cushing's disease were successfully treated surgically. Three patients with nonfunctioning pituitary microadenoma managed conservatively. Pancreatic neuroendocrine neoplasms (pNENs) were diagnosed in 12 patients (mean age 17.0 ± 2.6 years): three patients with insulinoma successfully resected (two resected and one exhibiting perineural invasion) and nine patients with nonfunctioning adenomas (NFAs).
Conclusion
Pituitary adenomas, PHPT and pNENs are encountered in the paediatric and young adult MEN 1 population. Successful outcomes are typically achieved using standard medical and surgical paradigms; however, parathyroidectomy was associated with a substantial complication rate.
Objective
Glucocorticoids constitute a considerable risk for developing osteoporosis in both younger and older adults. However, currently available bone imaging modalities and fracture‐risk assessment tools do not adequately capture the dramatic changes in bone microarchitecture, heterogeneity of glucocorticoid exposure, the impact of chronic disease and other osteoporosis risk factors on the assessment of osteoporosis in these individuals.
Design
A narrative review is presented, following a systematic search of the literature from 2000 to 2021.
Results
Our current appreciation of glucocorticoid‐induced osteoporosis (GIO) is focused on older populations, with limited evidence to guide the investigation, risk assessment and treatment in premenopausal women and men less than 50 years. The impact of the underlying chronic disease on secondary osteoporosis in these younger adults is also poorly understood.
Conclusion
Through this narrative review, we provide a comprehensive overview of and recommendations for optimising the management of this common cause of secondary osteoporosis younger and older adults.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
