Bilateral inferior petrosal sinus sampling in the diagnosis of ACTH-dependent Cushing's syndrome: experience in a tertiary hospital.

Objectives: Bilateral inferior petrosal sinus sampling (BIPSS) is a useful test for differential diagnosis of central vs. ectopic adrenocorticotropic hormone (ACTH)-dependent Cushing's syndrome (CS). We provide a description of the protocol used in our Center and an analysis of its diagnostic accuracy.

Management of a ruptured intraventricular aneurysm arising from distal anterior choroidal artery (AChA): pediatric case report.

Intracranial aneurysms arising from the distal anterior choroidal artery (AChA) are uncommon entities, with less than 30 cases reported. A 4-year-old boy was admitted to the Emergency Department with a sudden onset of severe headache and vomiting.

[Acute vertebral fracture and vertebral reinforcement techniques].

The high incidence of fractures by fragility and, especially of the vertebral fractures in osteoporotic postmenopausal women, forces us to approach this subject once more. In this manuscript epidemiological data that indicates the magnitude of the problem will be updated. Treatment alternatives to decrease back pain produced by vertebral fracture are will be reviewed, and the prevention of the occurrence of new osteoporotic fractures of any type, through the administration of suitable antiresorptive and bone-forming pharmacological agents to increase bone mineral density will also be addressed.
