[Treatment of severe cervicofacial hemangioma with interferon alpha-2b].

Background: Indications for active treatment of hemangiomas are those lesions which, by virtue of their size and site, compromise vital structures. The treatment of choice is oral or intravenous corticosteroids, but interferon alpha may represent alternative therapy.

Case Report: A 15-day-old girl was admitted for congenital hypothyroidism.

[Paraneoplastic Cushing's syndrome. Pseudotumors of the thymus occurring after correction of hypercorticism. 3 cases].

Ectopic ACTH-secreting tumours responsible for paraneoplastic Cushing's syndrome are invisible at radiography in about 50 percent of the cases. In this situation, the current attitude is to correct the hypercorticism and then embark on a regular morphological monitoring in search of the initial tumour with the purpose of removing it. We report the cases of 3 patients who had a paraneoplastic Cushing's syndrome of unknown origin in 1 case and consecutive, in 2 cases, to a bronchial carcinoid tumour initially occult and discovered 30 and 42 months respectively after the onset of the disease.

Usefulness of the corticotropin-releasing hormone test during bilateral inferior petrosal sinus sampling for the diagnosis of Cushing's disease.

Inferior petrosal sinus blood sampling for ACTH measurement (IPSS) is used for the differential diagnosis of ACTH-dependent Cushing's syndrome and for the preoperative location of pituitary microadenomas. Intermittent ACTH secretion from pituitary adenomas may result in insignificant differences between petrosal and peripheral ACTH levels at the time of sampling. Thus, pituitary stimulation during IPSS may improve the procedure.

Study of correlation between intradiscal pressure and magnetic resonance imaging data in evaluation of disc degeneration. Therapeutic issue with percutaneous nucleotomy.

Intradiscal pressure and volume measurements using discomanometry were correlated to features of degeneration noted with magnetic resonance (MR) imaging in 36 discs in patients scheduled for percutaneous nucleotomy. Discomanometric data (intradiscal pressure and degree of pressure loss at 0 and 60 seconds after intradiscal infusion, area under the pressure curve, and discal volume) were not correlated with the MR data (degree of disc height loss and degree of signal intensity loss on T2-weighted images). Results of nucleotomy were strongly correlated with discomanometric data but not with the studied MR factors.

[Diagnostic contribution of the new imaging systems in arterial and nerve disorders of the posterior fossa].

Giant aneurysms of the vertebrobasilar system are rare, representing only 5% of intracranial aneurysms and are the cause of severe pseudo-tumoral of hemorrhagic syndromes. Their endovascular or surgical treatment is always very dangerous. The basilar megadolicho-artery, of congenital origin, is frequently expressed by a hemispasm or facial neuralgias.
