Effects of acetylmethadol on plasma testosterone.

Plasma testosterone levels were measured in a group of 13 men maintained on acetylmethadol for treatment of opiate dependence. Prior to acetylmethadol administration, plasma testosterone levels were within normal adult ranges. Four hours following ingestion of acetylmethadol, plasma testosterone levels were significantly depressed and continued to fall 7-9 hr after drug administration. Plasma testosterone levels remained low 24-25 hr after the drug was taken, but, 48 hr following drug, plasma testosterone levels rose to values approximating those prior to drug. Depression of plasma testosterone levels following acetylmethadol ingestion was not only statistically but also biologically significant, since in many patients the levels were below the normal range for adult males.

[Multiple angioleiomyomas of both lungs. Probable hamartomatous tumors. Very late death due to respiratory insufficiency].

Case presentation : Multiple tumor nodules in both lungs, identified by biopsy and necropsy, in a 48 year old woman, 8 years after radiological discovery ; death due to respiratory failure after long tolerance ; peculiar angio-leiomyomatous type pulmonary tumors. This purely pulmonary tumor disease is difficult to understand ; the most probable hypothesis envisaged is that of hamartomatosis ; comparison with certain general dysplastic disease is possible, and in particular Bourneville's disease and lymphangio-myomatosis.

[Malformed tumoral hemangioma of the mediastinum. Apropos of 10 cases].

The malformed tumoral hemangioma of the mediastinum is highly specific tumoral entity, which must be distinguished from other varieties of hemangioma -- tumors arising in young subjects above all, and frequently large tumors of the mediastinum, whose radiological discovery leads to the most disturbing suppositions. It is however a benign tumor, most frequently surgically curable. Il is not so rare as it is said to be, at least in the child: it can be evoked in certain cases and even characterized sometimes. It is always better to avoid operative surprises in this connection, in this surgery of the mediastinum.
