Primary mediastinal tumors.

Primary mediastinal tumours (PMT) are rare, they include many different histological types, but lymphomas, thymomas and neurological tumours make up most of these tumours. Their symptomatology is often poor and they are in many cases discovered by routine thoracic radiography. Diagnosis mainly relies on medical imagery and on biopsy by mediastinoscopy or by CT-Scan controlled needle puncture.

Variant form of popliteal artery entrapment syndrome.

A forty-six-year-old, non smoker, patient presented with an intermittent claudication of the right calf, clinically compatible with a low popliteal artery obliteration. Arteriography showed an irregular intercondylar popliteal artery and oblitered low popliteal and anterior tibial arteries. Surgical posterior access showed a faulty insertion of the mediate gastrocnemius caput responsible for popliteal artery entrapment syndrome and for aneurysmal dilatation of the popliteal artery above compression.

Aneurysm of the descending thoracic aorta in a young woman.

The diagnosis of a thoracic aortic aneurysm in an otherwise healthy young woman is a very rare occurrence. The Authors report the case of a woman aged twenty-two in whom such an aneurysm was discovered the day after delivery. Physical signs and radiological documents are presented and early surgical treatment is described.

[The application of informatics to mercury gauge plethysmography].

In this study, the authors present a computerized mercury-gauge plethysmography device. The electrical signals collected by the plethysmograph are sent to the computer where they are analyzed by a specially devised interpretation program. The graphs are flashed on the screen, the parameters are automatically and instantly calculated, and a printed-out medical report may be obtained at the end of the test.

Consecutive infected aneurysms caused by salmonella.

Treatment of infected aneurysms consists of operation, which depends on the location and pathologic type, and antibiotic therapy, before and at least six weeks following operation. The authors present a case of two consecutive aneurysms occurring in a patient with Salmonella infection. Full recovery was obtained after surgical excision of the aneurysms, prolonged antibiotic therapy, and cholecystectomy.
