[Quantitative echographic assessment of muscular physiopathology].

The evaluation of muscular contraction is one of the main variables in muscular reeducation treatment protocols. US depicts muscular structure and size, as well as changes in both. A real-time US unit with 5/7.5 MHz probes and a computer with advanced software were used; the US unit was modified so as to reduce scanning times and to yield a high number of images/second (about 45). During endoscopy, a higher number of intermediate positions can thus be found between rest and contraction, which yields more statistically significant results. The US unit is connected to a video-recorder and to an electrostimulator to obtain isometric and isotonic contractions; the latter unit is connected to the US unit so that the electric and the US energies can be emitted simultaneously and the synchronism of the contraction and of the beginning of the electric stimulation can be assessed. Besides normal control subjects, patients with hypotrophic recto-femoral muscle were examined: the results were collected in a databank useful to choose the most appropriate treatment, to follow patients during therapy, to evaluate the final results and finally to be used in sports activities.

[Ultrasound and color Doppler in the diagnosis of vasculogenic impotence].

Echo-color-doppler is a non invasive diagnostic technique which can provide data about arterial and venous vascular circle of the penis with greater precision than Doppler CW. In the tumescent phase after a PGE1 injection the systolic velocity (SV) reaches a rate higher than 25 cm/sec and the diastolic velocity (DV) higher than 2 cm/sec, resistance index (RI) > to 0.70 with evident colour marked from 1 to 3 KHz. In erection arterial flow decrease and SV is lower than 25 cm/sec with DV lower than 2 cm/sec or with negative values; RI < to 0.70 or negative. The data are confirmed by clinical investigation and traditional diagnostic exams in normal and pathological patients. Echo-color-doppler reduces invasive exams and acquires a primary position on the diagnostic scale of impotence.

[Transcutaneous renal needle-biopsy guided with ultrasonics].

Authors performed percutaneous renal biopsy guided by ultrasounds in 10 patients in whom urography was dangerous or did not provided good renal images. The advantages of this method are in the directional and dimensional accuracy of ultrasound scanning, so that the exact topography of the kidney can be established. The use of ultrasonically guided renal biopsy is mainly recommended in iodine medium idiosyncrasy, in myelomas and renal failure. This method can be preferred in order to establish the exact topography of kidney, in acute anuric renal failure, in chronic failure (when high doses of iodate contrast are needed), and in the presence of cyst.

[Thoracic outlet syndromes. Arteriographic aspects].

Chest outlet syndromes are characterized by pain symptomatology caused by (congenital or acquired reasons) compression of the vasculo-nervous bundle. After a brief mention of the anatomy of the question, the indications and angiographic technique are reported, special reference being made to certain positions and dynamic tests which increase symptomatology and highlight arteriographic findings. These are clearly identifiable in the pictures and offer documentary evidence of the cervical rib syndrome, scalenus syndrome, small pectoral syndrome, the hyperabduction syndrome and the costoclavicular syndrome. Differential diagnosis should consider a number of painful syndromes of the upper extremity of purely neurological interest (involvement of the brachial plexus). Vascular diseases such as arteriosclerosis, Takayasu's disease, etc., osteo-myo-articular and ORL sector diseases should also be taken into account. Arteriography is able to identify with precision the causes of the clinical syndrome and to guide surgical exploration of the supraclavicular fossa with excellent chances of success.

[Transhepatic percutaneous cholangiography with the Chiba needle in diagnosis of cholestasis].

A technique originally described by Okuda has been employed to study 78 patients suffering from cholestatic syndrome. Visualization of the biliary system was obtained in 70 (89.7%). Of these, 65 presented dilatation of the bile ways whereas in 5, the biliary tree was normal. The 8 cases in which no visualization was obtained were later examined with other techniques and 6 proved to be suffering from intrahepatic cholestasis. In patients with extrahepatic obstruction, the biliary system was visualized in 97%, while in intrahepatic cholestasis, the percentage was 45.5%. The main indication for PTC is the speed at which intrahepatic cholestasis can be distinguished from the extrahepatic type; in the second event, it always pinpoints the site of the impediment, though less frequently the nature of the lesion and its extent. No complications requiring emergency laparotomy were ever encountered. Percutaneous transhepatic cholangiography with Chiba needle is a simple, reliable inexpensive method which gives excellent results in the study of patients with cholestatic syndrome.
