Overt hypercortisolism causes reduction in bone mass and density. The effects of subclinical Cushing’s syndrome (SCS) on bone markers and structure are still debated. We therefore studied 56 patients with adrenal incidentaloma: group A=35 (20 F 15 M, age 43–79, mean 64.6±1.5; BMI 29.9±0.9 kg/m2) without evidence of hypercortisolism, and group B=21 (10 F 11 M, age 51–76, mean 63.4±1.9, BMI 28.0±1.2 kg/m2) with SCS (i.e. w...

Background: In polycystic ovary syndrome (PCOS), insulin resistance (IR) might be involved in the development of endocrine and metabolic abnormalities. Visfatin, a protein secreted by adipose tissue, is suggested to play a role in pathogenesis of insulin resistance. However, the biological activity and regulation of this novel adipokine are still unknown.Objectives: To study the visfatin level in PCOS in Egyptian women and its relationship with IR and ma...

Background: Adipocytokines are biologically active substances produced by adipocyte with different physiological functions. Adiponectin, an adipocyte derived protein has multiple effects on homeostatic mechanism that regulate body weight and metabolism. Leptin, a signal of satiety to the brain, is considered as a proinflammatory adipocytokine. Thyroid hormones act on several aspects of metabolic and energy homeostasis influencing body weight, thermogenesis, and lipolysis in ad...

Background & Aims: The aims of transsphenoidal surgery (restoration/preservation of vision and amelioration of hormonal excess) are balanced against the risk of inducing new post-operative pituitary deficits. This study aims to assess the rate of new anterior hormonal deficits following transsphenoidal pituitary adenoma surgery in our centre and to assess whether the visibility of normal pituitary gland on pre-operative imaging predic...
