Power Doppler ultrasound of gallbladder wall vascularization in inflammation: clinical implications.

We investigated the role of Power Doppler US in the diagnosis and follow-up of cholecystitis. We reviewed the examinations of 21 surgical patients aged 27-48 years with US findings of cholecystitis. We performed B-mode and then Power Doppler US. Wall thickness and US structure, the presence/absence of stones, and US Murphy's sign were assessed at B-mode US, whereas only the presence/absence of wall vascularization was studied with Power Doppler. B-mode and Power Doppler changes post treatment were also investigated. Ultrasound showed wall thickening in all patients. In addition, positive Murphy's sign and/or gallbladder stones were seen in 6 patients each at B-mode US and wall vascularization in 7 patients with Power Doppler. Acute cholecystitis was diagnosed in these patients. The other 14 patients presenting wall thickening but no vascularization and negative US Murphy's sign were diagnosed as having chronic cholecystitis; 10 of them had gallbladder stones. Two of seven acute cholecystitis patients were operated on in the acute stage for the onset of complications and histologic findings confirmed the US diagnosis. As for the remaining patients, histology diagnosed chronic cholecystitis in 17, whereas wall thickening was not inflammatory in 2 cases. All the cases with early wall vascularization were eventually diagnosed as cholecystitis. Power Doppler US permits confirmation of the diagnosis of acute cholecystitis and distinguishing of chronic disease, which helps in planning of surgery.

[Assessment of varicocele recurrence with ultrasonography, color and power Doppler].

To study the postoperative recurrences of varicocele and the relationship between recurrences and sperm variables, we reexamined postoperatively 48 patients aged 14-56 years (mean: 25 years); the patients returned within a time range of 4 to 36 months. All the patients underwent physical examination, B-mode, color and power Doppler sonography (US); the images were acquired with the patient both supine and upright, both at rest and during Valsalva maneuver. We studied the incidence of recurrences and their bilaterality, the presence of reflux with or without functional maneuvers, associated conditions, surgical complications and the improvement of sperm variables; color and power Doppler findings were compared. The incidence of recurrences (28) and that of major complications (2) were related to the type of surgery: thus, no complications but 26 recurrences were found in the patients with spermatic vein ligation, versus only 2 recurrences but also 2 major complications (1 testicular ischemia and 1 hydrocele) in the patients with ligation of the spermatic cord venous channels. A right varicocele was found in 12 patients, which confirmed the frequent bilaterality of this condition; 8 patients with recurrences had improved sperm variables and 6 presented associated conditions. Our trial confirms that B-mode US, combined with color and power Doppler, can show recurrences, bilaterality, surgical complications and associated conditions and emphasize the role of these exams in the postoperative follow-up of varicocele. However, no method alone, without the evaluation of sperm variables, permits to select the patients to be reoperated on.

[Direct radiographic enlargement in mammography in everyday practice. Indications and limitations].

One thousand mammograms of non-preselected patients were reviewed in order to assess in how many and which cases an equivocal diagnosis can be made unquestionable and to test the value of follow-up exams with direct radiographic magnification. Direct radiographic magnification was used in all questionable cases (3%): 18 lesions were characterized by microcalcifications and 12 by nodules. Four cases were diagnosed as unquestionable (13%)-1 microcalcification and 3 nodules-while 13 patients were reexamined with mammography only. Even though the percentage variation from equivocal to unquestionable diagnoses is modest but significant, direct radiographic magnification is always useful in the follow-up.

[Significance of Harris' lines in fractures of the legs. Review of 53 cases].

Metabolic deficiencies of various kinds, acute or chronic diseases, and especially bone fractures may cause the formation of transverse thickening lines--known as Harris' lines--in bone metaphysis. The authors have selected 53 cases of lower limbs fractures in young people from their clinical reports and studies. These reports included X-ray studies or other data allowing comparison of the injured segment at a significant time interval from trauma. The importance of Harris' lines, which appear in a high percentage of cases, is discussed also from a medical jurisprudence point of view, as these lines clearly indicate the time when the fracture occurred and the subsequent evolution of the repair process.

[Milk of calcium renal lithiasis: uro-echographic evaluation].

From the fortuitous observation of a rare case of "milk of calcium" lithiasis in a renal calyceal diverticulum, the authors, having examined the etiopathogenetic implications of the disease and having considered the problems of differential diagnosis, discuss whether urography and sonography are a valid means of making a correct diagnosis and the consequent implications of a therapeutic nature which this pathology would involve.

[CT in the evaluation of the extension of bronchogenic carcinoma].

The computed tomographic patterns in 52 patients with histologically proven lung cancer are reported. The AA. underline the not sobstitutive role of C.T. scan in pre-operative determination of bronchogenic carcinoma extension. C.T. revealed a very high diagnostic accuracy in assessing the primary tumor extension and in evaluating distant macrometastases; however, in showing hilar and mediastinal nodal involvement has not the same accuracy. The AA. think that, at the present time, a combinate C.T. study of the chest, upper abdomen and brain is, in the most number of cases, a rapid, accurate and practical method to evaluate the extension of lung cancer.

[Changes in the plasma magnesium content in patients subjected to cardiopulmonary bypass].

Changes in plasma magnesium content in 17 patients operated in extracorporeal circulation are reported. Values were low at the end of the operation, but rose at the end of the first day to achieve spontaneous resolution of the condition within 3 days. No close relationship between such loss and immediate postoperative arrhythmia could be discerned. Attention is, however, drawn to 3 cases in which ventricular fibrillation was not resolved until electric shock treatment was preceded by the administration of magnesium sulphate.
