[Ultrasonographic study in breast immersion]. / L'esame ultrasonografico in immersione della mammella.

100 breast symptomatic patients have been examined with ultrasound, using an automated water-path scanner (Senomatic 3D CGR), and commercial B-mode or real-time scanners. All the patients were also examined with xeromammography. Normal breast patterns, as well as benign and malignant breast lesions, are presented.

[Comparative diagnostic value of echography and oral radiologic examination of the gallbladder in relation to surgical findings]. / Valore diagnostico comparato dell'ecografia e dell'esame radiologico per os della colecisti al vaglio chirurgico.

For nearly 60 years, since it was introduced by Graham and Cole (1924), oral cholecystography (OCG) has been used as the imaging technique of choice in investigation of gallbladder disorders. Recently, the future of OCG has come into doubt, principally as a result of ultrasonography, with the advent of high-resolution real-time scanning. Stones are seen as echoes within the lumen of the gallbladder and are associated with an acoustic shadow, findings which are highly specific. On this basis, to evaluate the accuracy of ultrasonography in detecting cholelithiasis, the A. have performed by real-time cholecystosonography 60 patients with not diagnostic OCG in a group of 546 patients affected by gallbladder diseases. Our results have confirmed that sonography revealed 4 normal gallbladders, 51 gallstones and 1 primary gallbladder cancer, with 5 cases of false positive. The true false negative rate has been difficult to determine, as surgery is usually not performed after a negative study. The accuracy of cholecystosonography for gallstone diagnosis was found to be 88,1% for all three Crade's categories.

[Changes in intestinal transit time induced by bromopride in functional diseases of the colon]. / Modificazioni indotte dalla bromopride su tempo di transito intestinale nelle colopatie funzionali.

Intestinal transit time was studied in two groups of 8 patients with irritable colon. In the first group, the time was longer than normal, whereas in the second it was accelerated. Three subjects in each group received a placebo, while the other five received 60 mg/day bromopride for 15 days. No change in transit time was noted in the controls. Two subjects in Group I displayed a significant reduction in transit time after bromopride, while deceleration and normalisation were observed in 4/5 patients in Group II.
