[Prevalence of vitamin D deficiency and its correlation with PTH, biochemical bone turnover markers and bone mineral density, among patients from ambulatories].

Consequences of VD deficiency include rickets and osteomalacia. However, marginal concentrations of 25-hydroxyvitamin D (25(OH)VD) are associated with secondary hyperparathyroidism and osteoporosis. In this context, levels of 25(OH)VD capable to elevate parathyroid hormone (PTH) could be considered as insufficient.

[Subclinical Cushing's disease: presentation of three cases and critical review].

Unlike subclinical Cushing's disease, adrenal subclinical Cushing's syndrome is widely recognized. It is defined as an autonomous cortisol hyperproduction of mild intensity not causing specific clinical signs, but detectable biochemically as derangements of the hypothalamic-pituitary-adrenal axis function. Although Cushing's disease accounts for the majority of hypercortisolism states, subclinical Cushing's disease has been rarely reported.
