Patients with pituitary adenomas present with hypersecretion syndrome(s), and/or pituitary failure(s), and/or signs of mass effect, or incidentally. Pituitary function evaluation, visual acuity and field check-up, and MRI or at least CAT are compulsory for diagnosis, and for therapeutic approach; surgery for Cushing's disease, dopamine agonists for prolactinomas, somatostatin analogs or surgery for thyrotroph adenomas, surgery and/or somatostatin analogs and/or radiotherapy in acromegaly, surgery with additional irradiation in most adenomas of other types, or even expectation in some instances.

Mitochondrial diabetes affects up to 1% of patients with diabetes and is often unrecognised by the physicians. Maternally inherited diabetes and deafness (MIDD) resulting from the mutation 3243AG of the mitochondrial DNA is the most frequent mutation associated with mitochondrial diabetes. This review summarizes the range of clinical phenotypes associated with MIDD and outlines the advances in genetic diagnosis, pathogenesis and management of these patients.
