The Diabetes Control and Complications Trial (DCCT) was a landmark study that evaluated intensive versus conventional insulin therapy in patients with type 1 diabetes mellitus; the Epidemiology of Diabetes Interventions and Complications (EDIC) study continues to follow the same cohort of patients. Many of the key contributions that the DCCT and EDIC have made to our understanding of type 1 diabetes mellitus are discussed by the authors of this Review.

Biochemical control cannot be achieved by the use of somatostatin analogs alone in a large number of patients with acromegaly. Combination therapy with somatostatin analogs and the growth-hormone-receptor antagonist pegvisomant is, however, highly effective at normalizing levels of insulin-like growth factor I. In this Review, the efficacy and safety of somatostatin analog–pegvisomant combination therapy as a potential tool for the medical management of patients with acromegaly is discussed.

Very little is known about how the changes in body composition that occur around the time of menopause might affect subsequent risk of new-onset diabetes mellitus, as well as the management of pre-existing disease, in postmenopausal women. Here, Emily D. Szmuilowicz and colleagues discuss the potential relationship between menopause, diabetes mellitus and the use of postmenopausal hormone therapy.
Aromatase deficiency in men: a clinical perspective

Aromatase deficiency is an extremely rare syndrome that is characterized by congenital estrogen deprivation. Early diagnosis is a key consideration, and estrogen therapy should be initiated as soon after puberty as possible in order to avoid the skeletal complications associated with this disorder. Here, Rochira and Carani review the presentation, diagnosis and treatment of aromatase deficiency in men.
The genetic and molecular basis of idiopathic hypogonadotropic hypogonadism

Mutations in a number of genes have been identified in patients as the primary genetic cause of idiopathic hypogonadotropic hypogonadism. These genes encode proteins that regulate gonadotropin-releasing hormone (GnRH) neuron development, migration from the nasal placode to the hypothalamus, GnRH secretion or GnRH action. This Review discusses genes associated with hypogonadotropic disorders and the molecular mechanisms by which mutations in these genes may result in idiopathic hypogonadotropic hypogonadism.
